Description

 Dyeing machine applying treatment agent to textiles

Technical field

 The invention relates to a spray-type open-width pneumatic vibration acceleration dyeing machine, referred to as a spray-type dyeing machine, which belongs to a high-efficiency environmental protection type dyeing and processing machine.

Background technique

 The spray type dyeing machine referred to in the present invention refers to that when dyeing or other processing, the dyeing liquid and the processing liquid form a fine-grained manner to contact the fabric, and the fabric can be freely expanded into the open or flat web. And through the cloth guide tube, the moving fabric in the cloth guide tube also forms a high-speed airflow at the lower end of the cloth guide tube, thereby causing an unbalanced pressure in the air flow between the upper and lower end surfaces of the cloth guide tube to form the upper end surface of the fabric. The static pressure on the upper side is greater than the static pressure on the lower end surface, so that the fabric can obtain pneumatic levitation, expansion, and acceleration by the action of high-speed airflow, and it can also use the interaction of unbalanced pressure to produce moving fabric. Periodic and violent vibration motion to accelerate the penetration of the dye into the interior of the fiber tissue. In addition to achieving high efficiency, low energy consumption, low bath ratio, and low pollution, it can also achieve fiber separation and solution for various types of fabrics. Twisting and drying functions.

 In particular, the present invention relates to the effect caused by the pressure of air currents formed by the dual polarization in the cloth guide tube. In addition to improving the accelerated penetration and diffusion of dyes, it can also quickly remove impurities between fabric fibers, making desizing, Refining, bleaching, soaping, water washing and other operations can be realized quickly, and the purpose of dyeing can be achieved in a very short time.

 Generally, the existing air-flow type dyeing machine or liquid-flow type dyeing machine, the dyeing and circulation movement force given to the fabric are completed by the action of the cloth belt wheel and the actuating nozzle, and the downstream side of the actuating nozzle Most of the cloth guide tubes also use small-diameter round tubes as circulation paths to control the kinetic energy so as not to spread excessively and stall, so as to achieve the basis of speed efficiency requirements. Therefore, when the fabric passes through the nozzle and the cloth guide tube, it is restrained and pressed to form a rope to achieve the purpose of dyeing. Therefore, the existing air-flow and liquid-flow dyeing machines, when dyeing processing, use separate air or liquid to actuate nozzles or generate power in a combined manner to force the fabric to enter through the cloth guide tube. The above-mentioned conventional air-flow type dyeing machine is defined as a person who has an air-flow operating nozzle on the upstream or downstream end of the current liquid-jet (jet) dyeing machine. Its main purpose is to soften the hard action of the dyeing liquid by using the auxiliary power and characteristics of the gas, and at the same time to obtain a dyeing operation with a low bath ratio.

Common air-flow dyeing machines are divided into high temperature and high pressure type and normal temperature and pressure type. It is big in structure Contains storage tank, cloth guide tube, belt wheel, dye-actuated nozzle, gas-actuated nozzle, cloth dispenser, dye-dye pump, blower, heat exchanger filter for temperature rise and control element, etc. Both the cloth guide tube and the storage groove are arranged axially on the upper side of the cloth storage groove. The upstream inlet end and the downstream outlet end of the cloth guide tube communicate with each end of the cloth storage tank respectively. During the dyeing process, a cloth wheel can pull the fabric in the front end of the cloth storage tank into the ^ nozzle, by ^ ^ The dyeing liquid and gas sprayed from the nozzle cause the acting force to be generated at the same time, forcing the fabric into the rear end of the storage tank through the cloth guide tube, and the dye liquid and gas discharged from the cloth guide tube pass through the cloth storage The return pipe at the upper and lower sides of the tank is guided by individual dyeing liquid pumps and blowers to pressurize the fabric entering the back of the cloth storage tank to the front of the cloth storage tank and then pulled up by the belt wheel, so it constitutes a continuous circular dyeing And processing operations.

 In the drawing, FIG. 1 shows a general air-flow dyeing machine, and FIG. 2 shows a general liquid-flow dyeing machine, which both include a cloth storage tank A and a cloth guide pipe A1. At the upstream end of A1, dyeing liquid is used as the moving nozzle All or gas is used as the moving nozzle A12 (for simplicity, the above-mentioned dyeing liquid is used as the moving nozzle All and gas is used as the moving nozzle A12. Acting nozzle A2 represents), and the downstream end outlet forms a passage with the rear end of the cloth storage tank A, so that the fabric B can circulate in the cloth guide tube and the cloth storage tank. During the dyeing process, the fabric B placed in the cloth storage tank A can be pulled up through the belt wheel A3 and introduced to the actuating nozzle A2, and the actuating nozzle A2 ejects the dyeing liquid and gas, so that the fabric B can be applied. At the same time, the fabric B is forced to fall into the cloth storage tank A through the outlet of the cloth guide tube A1, and the dyeing liquid C in the cloth storage tank A can be guided by the return pipe A4 located below the cloth storage tank A. Lead to the dye pump A5. The gas is guided from the space above the cloth storage tank A to the blower D through the return pipe A6. The fabric B entering the rear end of the cloth storage tank A can be slid to the front end of the cloth storage tank A by the inclination angle or gravity formed by the rear end of the cloth storage tank and the action of potential energy, so as to be pulled up again by the belt pulley A3 It is reintroduced into the actuating nozzle A2, and a continuous dyeing process is obtained.

The commonly used air-flow dyeing machine is mainly driven by the simultaneous force generated by the dyeing liquid and gas ejected from the operating nozzle A2 at the front entrance of the power belt cloth wheel A3 and the cloth guide tube A1. The fabric B enters through the cloth guide tube A1, and also achieves the purpose of dyeing with a low bath ratio. The structure and operating principle of the actuating nozzle A2 both adopt a circular ring-shaped cross-section as the ejection port. Please refer to FIG. 3 and FIG. 4 in the accompanying drawings. In order to achieve the control of the ejection flow rate, or to facilitate the operation For the purpose, various adjustable actuation nozzles have gradually replaced traditional fixed or replaceable actuation nozzles. In fact, the operating principle and method of the adjustable actuating nozzle is still based on the traditional actuating nozzle, and it still constitutes a rope-like binding dye when the fabric passes through. For simplicity, related The existing adjustable actuation nozzles are not repeated here.

 The conventional air-flow and liquid-flow dyeing machines shown in Figs. 1 and 2 also use the same reference numerals to indicate the same parts or components. However, in the description, the air-flow type dyeing machine is mainly used. When the nozzle A2 is actuated, the discharge direction is such that all the discharged dye liquid or gas contacts the fabric at the downstream center to form a gathering and enclosing force. The fabric is formed by a throat located at the inner center of the annular nozzle A21. The cross-section space of the part A22 passed. For the dye solution or gas leaving the annular nozzle A21, the speed energy momentum immediately diffuses into the space inside the guide tube to form a normal cross-section thrust distribution. In order to prevent the excessive diffusion of momentum from causing a sharp decrease in cloth speed and saving kinetic energy consumption, and at the same time achieve the intended dyeing purpose, generally used airflow or liquid flow dyeing machines, which are used to actuate the nozzle A2 and the guide pipe A1 path The small-diameter round tube is used as the basis for applying power and saving energy. In essence, the use of the binding-type actuation nozzle A2 to achieve the circular dyeing of fabrics will basically make most fabrics inevitably scratched. The reason is that whenever the fabric passes through the actuating nozzle A2, the fabric is bound by the throat of the actuating nozzle A2 and the wall of the cloth guide tube A1, forcing the fabric to form a rope-like inflection dyeing, resulting in a workable unit The reduction in area makes it difficult to change the energy. Therefore, the actuating nozzle A2 must have sufficient momentum to successfully reach the expected circulation rate. In contrast, whenever the fabric enters the throat of the actuating nozzle A2 at high speed, it often causes the fabric to Scratched by the impact of the peripheral wall of the throat of the moving nozzle A2. When the spray force of the moving nozzle A2 is too large, the fabric is often greeted by high-speed jets. The impact of the surface will cause excessive deformation or breakage of the fibrous tissue and detachment of the fibers, but if the spraying force of the actuating nozzle A2 is reduced, the dye solution will not easily penetrate into the interior of the folded fibrous tissue, and The moving speed of the fabric will then slow down, which will increase the cycle of the dyeing cycle, which is not conducive to the progress of dyeing.

In addition, when the fabric passes through the nozzle A2, the inflection of the fabric B in the weft direction is often excessively tight, which causes a line-shaped flower pattern or a line-shaped dead mark. From the perspective of fluid mechanics, if the activation nozzle A2 gathers all the power to a small part, it is a reasonable way to achieve the transformation of energy to accelerate the movement of the fabric, but only by the above-mentioned bound type activation nozzle The application method of A2, it is really difficult to make the dye fully penetrate into the fabric, because any object ^ other media penetrates into it, the object needs to provide the relative convection environment and space at the same time to be smooth achieve. In other words, once the dye molecules in the dye liquor are absorbed by the fabric fibers, the liquid molecules that carry the dye into the fabric fibers must leave immediately. Only in this way, other liquids with dyes can get the opportunity to enter the fiber again. However, ^ liquid molecules detach from the interior of the fiber tissue, at least the energy required to cut off the forces of mutual attraction between the liquid molecules and the fibers, so the liquid molecules trapped in the deep layer of fabric collapse, in order to get the opportunity to leave, you need to use Considerable energy to expel. Therefore, in order to make up for the blind spot of dyeing and other processing, the commonly used air-flow or liquid-flow dyeing machines need to extend the working time during the dyeing processing operation. The nozzle A2 is activated to achieve continuous dyeing or processing. The opportunity of infiltration of the liquid to achieve the desired leveling and processing purposes, resulting in a very time-consuming and laborious dyeing process.

 The moving amount of the nozzle A2 applied to the fabric is calculated based on the speed of the fabric when it passes through the central throat A22. After the fabric leaves the central throat A22, its power speed will decrease rapidly. The reason is that the nozzle is activated. The positive cross-sectional area of the annular nozzle A21 of A2 is smaller than the positive cross-sectional area of the downstream guide pipe A1, causing a diffusion effect. When the fabric leaves the central throat A22, the fabric is also directly decelerated by the diffusion of the dye solution or airflow, but because the fabric is not fluid, it can only be used as a change between the corresponding speeds in a buckled manner. Or heavier fabrics are particularly noticeable. Therefore, the fabric often overlaps too tightly in the cloth guide tube, resulting in a piston-type push. This can lead to severe creases or discoloration of the fabric, and also increase the friction between the fabric and the tube wall. In fact, in the conventional gas and liquid dyeing machines, after the fabric passes through the nozzle A2, most of the weight in the cloth guide tube will be from the upper half of the cloth guide tube due to the increase in space. The cross-section gap quickly leaves the cloth guide tube, so that the efficiency of kinetic energy work cannot be exerted. Therefore, the chance of the dye to penetrate into the fabric also decreases. When the fabric leaves the cloth guide end, the air-flow dyeing machine can The swelling characteristic blows out the bundle-like fabric to change the position of the cloth surface. However, after a long period of cyclic action, the fabric often forms a spiral columnar phenomenon. Therefore, air force still cannot solve this phenomenon. Some air-flow dyeing machines are generally not suitable for dyeing cotton fabrics with a large weight per unit length. The fabric only accepts the spraying and actuation of the actuating nozzle A2 in a condensing mode during the continuous circulating movement, which causes a lot of blind spots in the dyeing, and the dyeing effect is obviously not ideal.

The general air-flow dyeing machine is a batch dyeing machine. The amount of dyeing of a batch of fabric depends on the size of the cloth storage tank. If the capacity of the general cloth storage tank is 100 to 100 For 200 kilograms, if a large number of dyeing operations are to be performed, multiple cloth storage tanks can be combined with each other or divided into multiple grooves in a large cylindrical tank, so the dyeing capacity is divided by the space in the cloth storage tank A space. In addition to the size, there is a certain unit time limit for each cycle of passing the nozzle A2. The purpose is not to affect the leveling effect and to be applicable to different types of fiber fabrics. Therefore, the fabric dyeing cycle is generally about two minutes. The moving force of the fabric in the cloth storage tank is mainly provided by the inclined angle formed by the body of the cloth storage tank A and the gravitational potential energy generated when the fabric is stacked. In particular, air-flow dyeing machines use less liquid than conventional liquid-flow dyeing machines, so the fabrics do not have sufficient floating liquid volume and liquid flow force. The design of the cloth storage tank or appearance is generally uniform. J shape with English letters Or o, u and other font structures to correspond, the purpose is to borrow the same shape of the cloth storage tanks, to borrow the storage tanks from the front and back sides of the relatively vertical sections or high inclined angle arc surface In order to achieve the natural sliding effect of the gravity generated by the stacked fabrics, in order to prevent excessive friction on the cloth surface and reduce the sliding resistance, a lower friction panel is generally provided on the lower end plate surface of the cloth storage tank. Or round strips, so that the cloth surface will not cause abrasions. Therefore, the cloth storage tank A of a general air-flow or liquid-flow dyeing machine is to achieve the smoothness of the fabric movement, except that it depends on gravity, potential energy, and bath ratio. In addition to the weight of the dyeing solution and the allowable limit of creases caused by various types of fiber fabrics, the same cycle action principle is used to distinguish between different shape structures to achieve the purpose of dyeing processing.

 FIG. 5 shows another liquid flow dyeing machine invented by the inventor of this case, which is disclosed in Taiwan New Patent No. 89941, Chinese Utility Model Patent No. ZL93209236.5, Chinese Patent Application No. 93105099.5, and U.S. Invention Patent No. 5,381,678. The present invention is a further improvement based on the characteristics and disadvantages of the liquid dyeing machine of the prior art.

 As shown in FIG. 5, the liquid flow dyeing machine is substantially the same in circulation system structure as the common air-flow dyeing machine shown in FIG. 1, and includes a cloth storage tank A and a cloth guide pipe A1 provided above, so that The two front and rear axial ends of the two are connected to each other to form a passage, wherein an actuating nozzle A2 is provided at the front end entrance of the cloth guide tube A1, and a cloth wheel A3 is provided at the front end of the cloth storage tank A for The fabric B is pulled up from the cloth storage tank A and introduced into the operation nozzle A2 and enters the cloth guide tube A1. The function of the operation nozzle A2 is to eject the operation dye liquid to make the fabric B dye, and force the fabric B and The dyeing liquid C flows into the cloth storage tank A through the cloth guide pipe A1, and the dyeing liquid C in the cloth storage tank A can be guided to the dyeing liquid pump through a return pipe A4 provided on the lower side of the front end of the cloth storage tank A. A5, the dyeing liquid pump A5 can introduce the pressurized dyeing liquid into the actuating nozzle A2 through the pipeline A8, and then drive the fabric B to flow through the cloth guide pipe A1 by the actuating force ejected from the actuating nozzle A2, where A plurality of spaced-apart dyeing liquid guide nozzles A61 are provided on the flat tube wall on the lower side of the cloth guide tube A1, The dyeing liquid C can be pressurized by the dyeing liquid pump A5 and then passed through the pipe A7 ^ dyeing liquid driving pipe A6, and sprayed from the dyeing liquid guiding nozzle A61, and sprayed on the fabric B in the downstream direction of the cloth pipe A1 to improve the fabric B dyeing effect and increase the migration rate.

 Therefore, in view of the characteristics and defects of the existing liquid-flow dyeing machine and air-flow dyeing machine, the present invention provides another better spray-type dyeing machine.

Object of the invention

The main object of the present invention is to provide a spray-type dyeing machine, in which an actuating nozzle is not provided at the front entrance of the cloth guide tube, and the front and rear entrances and exits of the central and upstream and downstream tube walls form a flat bottom parallel wide cross-section path so During processing, the fabric can be freely expanded into an open or flat web. Through the cloth guide tube. Therefore, the fabric can no longer be constrained and oppressed by the nozzle and the small-diameter circular cloth guide tube in the past. It can solve the abrasion of the cloth surface and various thick and thin striped flowers, and the occurrence of linear dead marks. Problems that often occur with pattern dyeing.

 Another object of the present invention is to provide a spray-type dyeing machine, in which a plurality of spaced-apart airflow guide nozzles are provided on the lower flat plane pipe wall in the cloth guide pipe, and a spray is provided in the upper side of the cloth guide pipe.

Therefore, in the dyeing process, it can achieve the dyeing processing effect of low bath ratio, low energy consumption and low pollution.

 Yet another object of the present invention is to provide a spray-type dyeing machine, in which the fabric can pass through the cloth guide tube in a flat or flat web shape, and the cloth guide tube is internally caused by the high-speed pushing air flow sprayed from the lower side of the fabric. The pressure imbalance occurs on the air flow on the upper and lower sides of the fabric, which promotes the fierce counter-polarization effect of the air flow on the upper and lower sides of the fabric, which causes the fabric to move periodically and violently. Therefore, it can be used whenever the dye contacts the fabric. The action of motion promotes the dye to penetrate into the interior of the fibrous tissue, thereby increasing the exhaustion rate and diffusion rate of the dye in the fiber, so as to achieve high efficiency, and the dyeing process can be completed in a very short time.

 Still another object of the present invention is to provide a spray-type dyeing machine, in which the static pressure of the airflow on the upper side of the fabric is greater than the airflow on the lower side of the fabric when the fabric passes through the cloth guide tube. It tends to be close to the plane tube wall located at the lower end of the cloth guide tube. The static pressure on the upper side of the fabric can also be used to force the lower side of the fabric to diffuse the airflow at high speed, which can only be driven continuously through the left and right sides below the fabric. Out. Therefore, in addition to providing all the fabrics that can pass through the cloth guide tube to achieve continuous expansion, it can also effectively solve the problem of curling of general elastic fabrics.

 It is still another object of the present invention to provide a spray-type dyeing machine, in which the fabric is in the cloth guide tube during dyeing, and besides the high-efficiency dyeing purpose can be achieved by periodic violent vibration, the fabric can also be achieved at the same time. The functions of splitting, untwisting and drying, if adjusted to change the air speed, can also achieve a variety of different feel.

 Yet another object of the present invention is to provide a spray-type dyeing machine, in which, in addition to periodic and violent vibration, the fabric can achieve a dyeing effect with a small amount of liquid and a high concentration, and at the same time, the fiber content can be improved. The ability to remove pure materials enables the previous operations such as desizing, refining, bleaching, and soaping to be completed quickly.

Another object of the present invention is to provide a spray-type dyeing machine, which can also be borrowed during water washing operation. The airflow guiding nozzle changes the flow direction through the communication pipe and the control element to make it spray a larger amount of water washing liquid to promote the rapid diffusion of impurities into the water washing liquid to achieve the purpose of rapid washing out. Dyeing and processing of fabrics to make up for the lack of air-jet dyeing

In order to achieve the above object, the spray dyeing machine provided by the present invention generally includes a cloth storage tank, a cloth guide pipe, a distribution pipe, a guide nozzle, a plane reflection action substrate, a spray nozzle, a dye liquid pump, a blower, a cloth placing plate, and a belt. Cloth wheels, gas-liquid separation screens, heat exchangers, filters, and various connecting pipes and control elements, etc. Among them, the storage tank and the cloth guide tube have a circulation path, and the dyeing liquid pump and blower are returned by each return and The conveying pipeline is connected, and the dyeing liquid and gas are sucked from each circuit and pressurized, and they are respectively input into the cloth guide tube and sprayed out. Therefore, the fabric can be dyed by the spraying of the dyeing liquid, and can be accelerated by the force of the air, so that the fabric can pass the guide. The cloth tube enters the cloth storage tank, and then the dyeing liquid and gas are pumped into the cloth guide tube and sprayed out. Among them, a flat bottom wide cross-section path is formed between the front entrance of the cloth guide tube and the downstream pipe wall, and the fabric can be freely expanded to open. It enters or passes through the cloth guide tube in a web or flat manner. The lower end of the cloth guide tube is across the cut-off surface of the flat pipe wall. A plurality of spaced-apart airflow guide nozzles are provided along the axial direction. The downstream side of the nozzle of the guide nozzle forms a plane reflecting action substrate by the plane tube wall, so that the ejected propelling airflow can be advanced downstream along the end surface of the substrate, and a spray nozzle is provided on the upper side of the guide tube. Therefore, during the dyeing process, the fabric can be pneumatically lifted, expanded and accelerated by the high-speed air flow ejected from the guide nozzle, and can be moved through the cloth guide tube. It can also be sprayed by the spray nozzle to form a fine-grained dyeing solution. Disperse the fabric and obtain dyeing, which also causes unbalanced pressure in the air flow on the upper and lower sides of the fabric guide tube, which results in lower airflow speed and lower pressure, and upper airflow speed and lower pressure, respectively. Therefore, the air flow on the upper and lower sides of the fabric constitutes a bipolar interaction counteracting effect, which in turn causes the fabric in the cloth guide tube to generate a periodical distribution of violent vibrations, thereby achieving high efficiency, low energy consumption, and low energy consumption. Bath ratio, low pollution dyeing process.

The shape of the cloth storage tank 1 is generally a circular tube when used at high temperature and pressure, and a square tube when used at normal temperature and pressure. Its shape and structure are designed to cope with low baths. Compared with the dyeing machine, the fabric moves smoothly, and it is more suitable for the 0, U or inverted L in the English alphabet to achieve the best use purpose and the smallest footprint. As shown in FIG. 8, the shape is designed with an O in the English alphabet, and the cloth storage tank 1 is formed by the outer shape. The cloth guide tube 11 is disposed directly above the cloth storage tank 1 so as to be axially arranged together. The bottom part of the cloth storage tank 1 is provided with a dye liquid return pipe 151, and an upper side space portion is provided with a gas return pipe 161. A working door hole 3 and a cloth belt are provided between the upper side of the front end and the entrance of the cloth guide pipe 11. Wheel 18 „The outlet 112 of the downstream end of the cloth guide tube 11 is located at the rear end of the cloth storage tank 1, so that the cloth storage tank 1 and the cloth guide tube 11 form a path for the fabric 2 to achieve the purpose of circulating and moving. The cloth guide tube The entrance of the front end of the 11 and the downstream tube wall form a flat bottom parallel wide cross-section passage, which allows the fabric to freely expand to reach the open or flat width state. The cloth guide pipe 11 is provided with a spray nozzle 14 on the upper side of the passage, and the outside of the passage A distribution is provided on the lower part of the guide tube 11 along the axial direction The tube 12 forms a common tube wall by the flat wall at the lower end of the guide tube 11 and the upper end tube wall of the distribution tube 12, which constitutes the actuating base plate 13 and the common flat tube wall (acting base plate 13). A plurality of segmented spaced-apart guide nozzles 121 are provided along the axial direction of the cross section. At the downstream section 112 of the cloth guide tube 11, the axial portion 113 communicating with the cloth storage tank 1 is located on the path. The upstream section is provided with a cloth placing plate 17, which is composed of a flat grid plate and pivoted to the turning portion 113 in a cantilever manner. The side wall 114 can be coupled to each other by means of an external power transmission device, so that the swing plate can swing in a longitudinal manner on the passage. The downstream section is provided with a gas-liquid separation screen 19 along the peripheral wall side of the cloth storage tank 1.

 Although in the embodiments shown in FIG. 8 and FIG. 9, the reflective actuation substrate 13 is designed as a flat-bottomed and wide structure, so that the fabric can be unfolded into an open or flat width freely, thereby improving the dyeing effect, the present invention does not It is not limited to this kind of flat-bottomed parallel wide structure. In fact, as long as the lower side wall surface of the reflective actuation substrate 13 or the cloth guide tube 11 is designed to have an appropriate width, the fabric to be dyed can be unfolded into an open width. The purpose of the present invention is to promote the dyeing effect. For example, as shown in FIG. 13, it is another embodiment of the present invention, in which the lower side wall surface of the reflective actuation substrate 13 or the cloth guide tube 11 is arc-shaped in outline, approximately 10% of the cloth storage tank. Concentrically arranged, it also has a suitable width for the fabric to be unfolded into a flat or open web. Therefore, the dye-promoting effect of the present invention can also be achieved.

The spray nozzle 14 on the side sprays out onto the fabric 2 in the cloth guide tube 11 so that the dye in the dyeing liquid is absorbed by the fabric and flows to the lowest part of the cloth storage tank 11 and continuously passes through the dyeing liquid return pipe. 151. The dyeing liquid pump 15, the filter 153, and the heat exchanger 154 are sprayed to the spray nozzle 14. The supply of dye or treatment agent is injected through the injection port 1511 on the dyeing liquid return pipe 151, and the gas part is communicated with the blower 16 through the gas return pipe 161, so that the gas is compressed by the blower 16 and then borrowed by the conveying pipe. 162 enters the distribution pipe 12 and ejects toward the downstream direction in the cloth guide pipe 11 through the guide nozzle 121, and advances along the end face of the reflection actuation substrate. There is another passage between the gas conveying pipe 162 and the dye liquid conveying pipe 152 165. Direction changing control valves 166, 163, and 155 are also provided on the passage 165 and each conveying pipeline. The purpose is to wash the work period or dye particularly thick fabrics. For example, when the yard weight is more than 600 grams, it can be controlled by The valves 163 and 155 are closed and the valve 166 is opened, so that the water washing liquid passes through the passage 165, and then passes through It enters into the distribution pipe 12 from the gas conveying pipe 162, and is ejected into the cloth guiding pipe 11 by the guide nozzle 121 in a gas-like manner. The purpose is to quickly diffuse the remaining impurities attached to the fabric into the washing liquid. in.

 The circulation circuit described above is substantially the same as the conventional air-flow type or liquid-flow type dyeing machine. In addition, it should be particularly noted that the guide nozzle on the lower pipe wall of the cloth guide pipe 11 described above

121, which can be further set as an adjustable guide nozzle according to the requirements. Please refer to FIG. 12, which is basically provided with a movable guide leaf plate 12101, a pivot lever 122, a driving link 123, and a movable guide leaf plate 12101. The shaft center 12102 at its left and right ends can be fixedly pivoted on the sleeve bearing 1101 at the left and right ends of the passage of the cloth guide tube 11.

The feature of the present invention is that, in the structure of the cloth guide pipe 11, the upstream end entrance 111 is not provided with a binding type actuating nozzle, as shown in the numbers All and A12 in Figs. The throat through which the fabric passes, please refer to the number A22 in Figs. 3 and 4, and the front and rear inlets and outlets 111, 112 and the middle upstream and downstream pipe wall form a flat bottom parallel wide cross-section passage. The size of this passage can be determined according to Depending on the width of the fabric or the need for expansion, it can reach the same width in the storage tank path at the maximum. Therefore, when dyeing, the fabric can be expanded freely to reach the open or flat state through the cloth guide tube 11, the fabric is in When passing through the cloth guide tube 11, it can be sprayed by the spray nozzle 14 on the upper side of the passage to form a fine material-like dyeing liquid, so that it is completely spread and covered on the upper end surface of the fabric 2, so as to allow moisture to pass from top to bottom. The method achieves the dyeing effect. On the other lower end surface of the fabric 2, a plurality of segmented guide nozzles 121 on the lower side of the path can be used to spray air at a high speed to form a cooperative power, so that the fabric 2 can obtain Pneumatic levitation and acceleration movement Driven by the high-speed air stream 11 also effects inherent fabric cloth guide tube 2 and down stream side of the pressure imbalance, which are formed below the faster stream The pressure is lower, the air velocity above is slower and the pressure is higher, so the interaction between the air flow on the upper and lower sides of the fabric creates a fierce confrontation of bipolarity, so that the fabric 2 moving through the cloth guide tube 11 can be comprehensive. Generates periodic violent vibration motion, and also counteracts the high pressure of the airflow on the upper side of the fabric to force the diffused part of the airflow pushed at a high speed to drive out through the left and right side ends of the fabric. Therefore, when the fabric passes the cloth guide tube 11, the fabric 2 In addition to obtaining high-speed power to accelerate the airflow to impart acceleration, the expansion effect can also be obtained by driving the diffused airflow at the left and right side ends. Therefore, the fabric in the cloth guide tube 11 can continuously move in an open state. When leaving the exit end of the cloth guide tube 11 and entering the cloth storage tank 1, the cloth cloth plate 17 on the path can also be used to make the fabric 2 touch the cloth cloth plate ₁₇ and then fall into the cloth storage groove 1 to make it fall. The fabric to the cloth storage tank 1 can obtain the expected optimal folding effect. At the same time, the air-liquid separation screen of the cloth storage tank 1 along the peripheral wall side can promote all the airflow of the fabric 2 quickly. It is discharged through the mesh so that the fabric does not cause air resistance or gas backflow when it is folded, so that except for a part of the discharged gas that flows to the front end of the storage tank 1 to achieve a balanced cylinder pressure distribution, most of the airflow is introduced through the return pipe 161 Inside the blower 16, the gas is compressed again, and then enters the distribution pipe 12 through the passage of the air flow conveying pipe 162, and is distributed to each of the guide nozzles 121, so that the air is pushed at a high speed to reflect along the plane of the lower end of the guide pipe 11. The end surface of the actuating substrate is advanced in the downstream direction. Next, the effect occurring in the cloth guide tube will be further explained.

According to Bernoulli's Law: "For a flowing liquid or gas, the faster the flow, the lower the pressure." Therefore, according to the above, when a high-speed pushing air flow is generated under the fabric 2, the static pressure under the fabric will be reduced, and the static pressure air flow formed above the fabric 2 will cause the pressure to increase due to the slower speed, which in turn will make the fabric 2 Due to the pressure of the airflow above and the effect of gravity, the fabric 2 can be forced to continuously push the airflow area at high speed, so that the fabric and the high-speed airflow are in close contact to increase the friction effect. In addition, the fabric can obtain the maximum energy given by air force. Therefore, whenever the fabric continues to approach the mainstream area where the high-speed air flow is pushed, the fabric will be resisted by the positive airflow and cannot continue to lean forward. It has enough power to push the front fabric away, so that the fabric can continuously rise and float on the plane tube wall, so it also prevents contact and friction between the tube wall. Therefore, whenever the fabric 2 is forced into the mainstream region where the airflow is pushed at a high speed, the positive airflow immediately generates a pressure wave to force the fabric to leave the mainstream region quickly. The pressure wave is generated by the speed energy being resisted and converted into pressure energy. Caused by. It can be affected by the reflection of the planar reflection acting on the substrate, and it can also have the same phase relationship with another wave peak, so that another pressure wave peak is reached instantaneously, which occurs continuously in the fabric in the cloth guide tube 11 in a periodic manner. Above, so that the fabric will be cyclic in any part Vibration movement, in which the magnitude of the vibration frequency is affected by the quality of the fabric, is actually determined by the momentum of the air velocity, so when dyeing or processing, it can be guided by the nozzle 121. The opening of the nozzle opening or the power output by the blower achieves the desired purpose. The periodic waveform vibration movement generated above is an effect caused by a large amount of energy to work. Therefore, in addition to each vibration, the fabric can be promoted. The loosening of the fibrous tissue structure allows the dye solution to obtain convective pathways, and also enables the dye to obtain the energy required to accelerate penetration into the fabric's fibrous tissue, thereby increasing the exhaustion rate and diffusion rate of the dye in the fiber. Therefore, in dyeing In addition to the purpose of increasing the movement rate and obtaining a small amount of liquid, high concentration, high efficiency, low energy consumption, low bath ratio, and low pollution during operation, the fabric can also achieve the effect of fabric fibrillation and ^ ". Can improve the removal ability of impurities in the fiber, so that processing operations such as desizing, refining, bleaching, soaping, and water washing can be performed quickly Completed in a very short period of time to achieve the dyeing or processing process.
