Description

Gas-liquid dyeing machine

The invention relates to a cloth dyeing device, in particular to a gas-liquid dyeing machine.

As we all know, the structure of the air-liquid dyeing machine mainly includes a circuit device and a nozzle arranged in the circuit device. The circuit device is formed by connecting a machine head, a cloth guide pipe, a cloth storage tank, and the like. The principle is that the cloth to be dyed is placed in the loop device, and the high-pressure dye solution is sprayed on the cloth through the nozzle to spray the cloth, and at the same time, the jet force is generated to drive the cloth to advance in the circulation device. Return to the nozzle through the cloth guide pipe and cloth storage tank for the next spraying. For example, the No. 325063 air-liquid dyeing machine announced in Taiwan Patent Gazette in January, 1987 belongs to the above-mentioned structure.

However, there are many shortcomings to be improved in this structure. For example, the No. 337795 air-liquid dyeing machine announced in Taiwan Province Patent Gazette in July, 1987 has an improved cloth guide pipe, cloth storage tank, and is provided with a nozzle that can select forward or reverse spraying dye liquor. This kind of structure effectively improves the problems such as cloth rope wrapping and knotting.

However, in the structure of the known air-liquid dyeing machine, the nozzles are not only used for spraying dyeing, but also must spray high-pressure dyeing liquid sufficient to drive the cloth, so that the cloth can circulate. Therefore, the dye solution pump must have a large horsepower and require a large amount of dye solution to achieve the above purpose.

Furthermore, since the cloth is folded and piled up in the cloth storage tank, it will inevitably produce creases after being pushed and pushed, which will be unfavorable for the dyeing of the cloth.

The object of the present invention is to provide a kind of air-liquid dyeing machine, which sprays and drives the cloth with the mixture of atomized dye solution and air, so the dye solution pump does not need a large horsepower, and only needs to use a small amount of dye solution.

Another object of the present invention is to provide an air-liquid dyeing machine, which uses air jets to drive the cloth, so that the dye solution pump does not need a large horsepower, and only needs to use a small amount of dye solution.

Another object of the present invention is to provide an air-liquid dyeing machine, which can eliminate creases caused by accumulation and extrusion of cloth during the cyclic dyeing process.

The air-liquid dyeing machine of the present invention mainly includes components such as blower, heat exchanger, air-liquid mixer, dye liquor pump, dosing tank, dye liquor return pipe, square linear nozzle, and linear nozzle.

According to an embodiment of the present invention, the blower blows out a strong air volume, and after being heated by the heat exchanger, it reaches the gas-liquid mixer. At this time, the dye liquid pump sucks the dye liquid from the dosing tank or the dye liquid return pipe, sends it to the gas-liquid mixer, mixes with the sprayed air, enters the square linear nozzle, sprays and dyes the cloth, and drives the cloth to move forward. When the cloth is moving and falling, the one-line nozzle sprays air regularly and intermittently, so that the cloth is folded in an N shape, and when the cloth advances to the front of the square linear nozzle again, another straight-line nozzle sprays air towards the cloth, blowing the cloth into a spherical shape, so as to eliminate its creases.

According to another embodiment of the present invention, it is not provided with a gas-liquid mixer, therefore, the air ejected by the blower is directly sent to the square linear nozzles after passing through the heat exchanger, so as to drive the cloth to advance with the ejected air. The dye solution sucked by the dye solution pump is sent to a linear nozzle, and the dye solution is sprayed on the cloth for dyeing.

Because the gas-liquid dyeing machine of the present invention utilizes the gas-liquid mixture, or completely only uses air, as the energy for spraying and driving the cloth, and the dye solution pump is only used to absorb dye, so the dye solution pump does not need a large horsepower, so the dye solution The amount of liquid used is very small.

The present invention will be described in detail below in conjunction with the accompanying drawings.

As shown in Figure 1, the gas-liquid dyeing machine of the present invention mainly includes: a blower 4, a heat exchanger 3, a gas-liquid mixer 2 with a jet atomizer 22 inside, a dye liquor pump 5, for storing the dye liquor Dosing tank 13, dye liquor return pipe 20 for collecting excess dye liquor, square straight nozzle 1, and straight nozzle 6,25. The principle of the present invention will now be described in detail with reference to examples.

First, when the blower 4 starts, it sucks in air through the air return pipe 7, blows out a strong air volume, and then sends it to the heat exchanger 3 for heating through the air ejection pipe 8, and then reaches the gas-liquid mixer 2. Simultaneously, the valve 12 below the dosing tank 13 is opened, and the valve 15 of the dye liquor return pipe 20 is automatically closed. Therefore, the dye solution pump 5 can suck the dye solution from the dosing tank 13 . After the sucked dye solution is sent out by the dye solution pump 5, it is controlled by the proportional switch 14 to automatically adjust the amount of the sprayed dye solution, and sent to the gas-liquid mixer 2 through the dye solution pipe 11. At this time, by means of the spray atomizer 22 arranged in the gas-liquid mixer 2, the dye liquor can be sprayed out in mist form, and mixed with a large amount of air sprayed by the blower 4, and then mixed with the gas-liquid The tube 9 enters the square straight nozzle 1 .

Under normal circumstances, the mixture of dye liquor and air is sprayed out from the forward jet port 532 of the square linear nozzle 1, and the strong jet force entrained by the mixture of dye liquor and air can not only spray and dye the cloth 29, but also Also drive cloth 29 to spray toward baffle plate 30, and run into baffle plate 30 and fall. At this time, the air in the air pipeline 23 is intermittently opened and closed through the intermittent control valve 24 with a predetermined rule, and the linear nozzle 25 is controlled to spray air sometimes and stop the air spray sometimes, so that the cloth 29 is folded in an N-shaped manner, neat and orderly The strata are stacked in the grid slot 19 . When the stacked cloth 29 advances to the cloth wheel 16, the air in the air pipeline 21 is introduced into the linear nozzle 6 and ejected toward the cloth 29 through the opening of the pipeline switch valve 10, and the cloth 29 is blown up into a spherical shape. Expand, and then enter the square linear nozzle 1 again to circulate the spraying.

During the above process, the excess dye liquor of the spray-dyeing cloth will gather at the bottom of the screen tank 19 and flow to the dye liquor return pipe 20 for repeated spraying and dyeing. The dye liquor return pipe 20 and the dosing tank 13 are respectively provided with a valve 15, 12 to control the outflow of the dye liquor. When the dye liquor pump 5 draws and sends out the dye liquor from the dye liquor return pipe 20 or the dosing tank 13, This proportional switch 14 can regulate how much the dye liquor is sent out, so as to determine how much time the dye liquor in the dosing tank 13 takes out.

In addition, the square linear nozzle 1 in the present invention is provided with multi-stage forward jetting ports 532 and reverse jetting ports 552, and the jetting ports can adjust the size of the jetting volume, which can be separately divided into one group or multiple consecutive groups. Under normal circumstances, the mixture of air and dye liquor is sprayed out from the forward injection port 532, driving the cloth 29 to move forward; Move in reverse to untangle knots.

In addition, as shown in Fig. 3 (a) and Fig. 3 (b), a jet atomizer 22 is arranged in the gas-liquid mixer 2, and the jet atomizer 22 is in the form of a circular tube, and is connected with the dyeing liquid pipe 11. A plurality of injection holes 32 are formed thereon. When the dyeing liquid enters the gas-liquid mixer 2, the spray hole 32 on the spray atomizer 22 sprays fine atomized dye, and blows a large amount of air from the blower 4 to mix with each other. At this time, the gas-liquid forms a powerful driving force. The energy is sent to the square linear nozzle 1, on the one hand, the cloth 29 is driven to advance rapidly, and at the same time, the cloth 29 is sprayed and dyed. Therefore, the present invention uses only a very small amount of dyeing liquor.

Although only one jet atomizer 22 is arranged in the gas-liquid mixer 2 in the drawings, it can also be designed with multiple jet atomizers 22 . And, it is also possible to only establish a spray single pipe in the gas-liquid mixer 2, or insert a dye solution pipe at any position in the blower 4 outlet pipeline, so that the dye solution is atomized by the injected air, and these changes are all included in within the scope of the present invention.

In addition, since the cloth 29 is folded in an N-shape in the mesh groove 19, creases will inevitably be produced after stacking and extrusion, which will be unfavorable for dyeing. And according to the air-liquid dyeing machine of the present invention, a linear nozzle 6 is provided at the position before the cloth enters the square linear nozzle 1 . The structure of the nozzle is shown in FIG. 2( a ) and FIG. 2( b ), which is roughly an elongated cylindrical shape, and a straight spray hole 31 is arranged on it. The linear nozzle 6 is connected to the air pipeline 21 and controlled by the pipeline switching valve 10 . During the circulation process of the cloth 29, whenever it passes through the linear nozzle 6, the cloth 29 will be blown and expanded by the air ejected from the linear nozzle 6, eliminating the creases caused by accumulation and extrusion, making the cloth 29 straighter and easier dyeing. Before the cloth 29 falls after colliding with the baffle plate 30, it is again blown and unfolded by another linear nozzle 25 which sprays air intermittently, and is folded in an open-width N-type. The structure of the linear nozzle 25 is the same as that of the linear nozzle 6, so it will not be described again.

Fig. 4 is a schematic structural diagram of another embodiment of the present invention. As shown in the figure, this embodiment mainly includes: a blower 4, a heat exchanger 3, a square linear nozzle 1, a dye solution pump 5, a dosing tank 13 for storing the dye solution, and a dye solution backflow for collecting excess dye solution Tube 20 and linear nozzles 6,25. Compared with the previous embodiment, a gas-liquid mixer is not installed here. The principle of this embodiment will be described in detail as follows.

When the blower 4 starts, it inhales air through the air return pipe 7, blows out a strong air volume, and then sends it to the heat exchanger 3 through the air ejection pipe 8 for heating, then from the forward injection port 532 of the square linear nozzle 1 Or reverse injection port 552 injection. The cloth 29 can be driven to advance rapidly by the strong jet force carried by the jet air.

At the same time, through the switch control of the valves 12 and 15 , the dye solution pump 5 can suck the dye solution from the dosing tank 13 or the dye solution return pipe 20 . After the sucked dye solution is sent out by the dye solution pump 5, it is controlled by the proportional switch 14 to automatically adjust the amount of the sprayed dye solution, and is sent to the straight nozzle 6 through the dye solution pipe 11, and the straight nozzle 6 sprays the dye solution to the Cloth 29 dyed.

The cloth 29 is driven by the square linear nozzle 1 to spray towards the baffle plate 30, and hits the baffle plate 30 and falls. At this time, the air in the air pipeline 23 is intermittently opened and closed through the intermittent control valve 24 with a predetermined rule, and the linear nozzle 25 is controlled to spray air from time to time, and stop the air spray from time to time, so that the cloth 29 is folded in an N-shape, neat and orderly The strata are stacked in the grid groove 19 . When the stacked cloth 29 advances to the cloth wheel 16, it is sprayed and dyed by the linear nozzle 6 again.

As described in the above process, in addition to the gas-liquid mixture as the kinetic energy of the spraying, the design of the present invention can also be changed to completely use the air jet to drive the cloth 29, and the dye solution pump 5 is only used to absorb the dye solution for spraying, so the dyeing The liquid pump 5 does not need to have high horsepower. And in the prior art, because utilize jetting high-pressure dye liquor to drive cloth, need use quite a large amount of dye liquor, the cloth and dye liquor ratio of traditional dyeing machine is 1: 8, and existing dyeing machine also needs 1: 4, and the present invention Only need 1:1 or 1:0.5. In comparison, according to the design of the present invention, the amount of dye solution used is extremely small, and even the realm of waterless dyeing can be achieved.

Fig. 5 is a partial cross-sectional view of the square linear nozzle 1 in Fig. 1 and Fig. 4, the nozzle 1 includes an upper nozzle chamber 51 and a lower nozzle chamber 52, and its internal structure is exactly the same, but for the sake of comparison, only the lower nozzle is shown in Fig. 5 Section of chamber 52.

The square straight line nozzle 1 has two operation modes of forward jetting of dye solution and reverse jetting of dye solution. During normal jet dyeing, the upper and lower nozzle chambers 51, 52 spray high-pressure dyeing liquid to the right and obliquely from the jet port 532, so as to drive the cloth to enter the nozzle 1 from the left, as shown by the arrow in the figure, and then send it out from the right . When it is found that the cloth rope is entangled and knotted, it can be changed into a reverse operation, so that the upper and lower nozzle chambers 51, 52 are changed from the injection port 552 to spray the dyeing liquid to the left and obliquely, so as to drive the cloth to move in the opposite direction. Remove the rope-like entanglement and knotting state of the cloth. Then select forward operation again to continue with normal jet dyeing.

The detailed construction of the nozzle 1 will be described below.

The nozzle 1 includes an upper nozzle chamber 51 and a lower nozzle chamber 52, both of which have identical structures. Now use the lower nozzle chamber 52 as an example for illustration. On the side facing the upper nozzle chamber 51, a plurality of forward injection ports 532 and reverse injection ports 552 are staggeredly arranged, which are respectively used for forward and reverse ejection of dye liquor, and The opening and closing of the forward and reverse injection ports 532 and 552 are respectively controlled by a plurality of first sliders 531 and second sliders 551 .

In the lower nozzle chamber 52, there are first and second drive wheels 57, 58, first and second worm gear sets 54, 56, first and second connecting rods 53, 55, and the aforementioned first and second slides. Blocks 531, 551, wherein the first driving wheel 57 is connected to the first slider 531 by the first worm gear set 54 and the first connecting rod 53, to drive the first slider 531 to open and close the forward injection port 532, and the second driving wheel 58 is connected to the second slider 551 through the second worm gear set 56 and the second connecting rod 55, and is used to drive the second slider 551 to open and close the reverse injection port 552.

Fig. 6 shows the operation situation of spraying the dye solution in the forward injection port 532. At this moment, the first slide block 531 is opened to expose the forward injection port 532, and the second slide block 551 closes the reverse injection port 552, and the dye solution is injected by the forward direction. The port 532 is ejected to the right and obliquely to drive the cloth to advance; Fig. 7 shows the operating state of the reverse jet port 552 spraying the dye solution, at this time the first slider 531 will close the forward jet port 532, and the second slider 551 will open Reverse injection port 552, the dye liquor is sprayed leftward and obliquely by the reverse injection port 552 to make the cloth advance backward.

In addition, if the output of the nozzle needs to be adjusted due to the different thickness of the cloth, it can be realized by directly adjusting the size of the forward and reverse injection ports 532, 552, without changing the nozzle as in the prior art.

Although the present invention has been described in detail with reference to the accompanying drawings and two embodiments thereof, the present invention is not limited thereto, and any modifications and changes made according to the spirit of the present invention and the scope of the patent application all should belong to the protection scope of the present invention .
