Description

Computer Direct Control Transfer Plotter Using Viscous Colorants

technical field

The invention relates to a plotter, in particular to a plotter which can directly transfer the viscous color paste to the surface of objects such as fabrics, roads or flat places under the control of a computer.

Background technique

At present, there are many known drawing methods. For relatively large graphic printing production, screen printing, heat transfer printing, color inkjet printing, plotter and manual methods are often used. When marking lines and patterns are painted on the road, they are generally drawn manually.

Screen printing is widely used, but it has the following disadvantages: For large-scale graphic printing, the size of the screen is required to be relatively large. Generally, it is necessary to use a letter cutter to draw the pattern on the paper, and then use a blade to hollow out the pattern. , consuming paper and manpower. If film is used, the cost will increase. Printing large patterns requires multiple plate making and splicing. After printing, the screen needs to be cleaned.

For the thermal transfer printing method, use a letter cutter to engrave the outline of the designed graphic on the composite color paper, and then pass the engraved part and the cloth to be printed through the thermal transfer machine, and heat it at high temperature. The pigments on the colored paper solidify on the cloth. This method has the following disadvantages: heating is required during transfer printing, and power consumption is large. When the color paper pigment is heated, part of the pigment will be dispersed in the air after heating, and not all of it will be printed on the cloth, which will pollute the environment to a certain extent. adverse effects on the health of workers. Compared with the screen printing method, the color contrast of the advertising banner printed by the thermal transfer method is poor, and the hiding power of the color is not strong. The color of thermal transfer is limited to the color of the color paper that has been produced, and cannot be adjusted arbitrarily, so the color is not rich.

Color inkjet printing technology is also commonly used in the form of printing. Its disadvantage is that when the size is large, the inkjet cloth itself has considerable weight, so be very careful when hanging it to prevent tearing; it cannot be directly sprayed on the cloth, nor can it be sprayed on the road.

The disadvantage of commonly used plotters is that they can only draw lines on paper.

Marking signs, marking lines and reminder texts on the road are generally filled in the corresponding positions manually with color paste. The disadvantage is that there are large errors in the reproduction of patterns and characters, and the construction efficiency is low. In the disclosed "multi-component road marking paint spraying and marking machine" (ZL200520136857.2) patent technology, the method of pressurized spraying is used to paint the road markings. The essence of this method is still to manually control the outline of the marking line. In the process of spraying, relatively cumbersome pressurized equipment is required, and the drawing of complex patterns cannot be automatically completed. At the same time, part of the paint is wasted in the form of mist during the spraying process, and the noise is also very large.

There are two main types of fabric printing materials commonly used, namely dyes and coatings. Paste is added to the dye used for printing to make a thick and viscous color paste. Paste is one of the main components of printing paste. No matter what kind of dye is used for printing on any fabric, a certain amount of paste is added to the printing paste, and the dye and chemicals are transferred to the fabric by means of the paste. Pigment printing materials are generally composed of paint colors, adhesives, fillers and additives. The biggest feature of pigment printing materials is that it is not affected by the properties of textile fibers. The paint color has no affinity with textile fibers. It forms a strong film with the help of adhesives and is firmly adsorbed on the fibers. In order to print a clear pattern and make the printing paste have certain rheology and thixotropy, it is necessary to add a thickener when preparing the color paste.

The commonly used adhesive printing materials mentioned above are low in cost, wide in sources, bright in color, can be colored on the surface of various materials, and have unique characteristics in terms of color hiding power. But there is no device that can directly use sticky printing material and utilize computer to carry out direct drawing.

Contents of the invention

The purpose of the present invention is to provide a transfer drawing device using commonly used viscous color paste as printing material. Under the control of the computer, large-scale drawing can be carried out on the surface of cloth, roads, flat places and materials suitable for coloring. Text transfer printing, accurately reproduce the original text content, and can change different colors to draw patterns with multiple colors.

In order to achieve the above object, the principle of the transfer plotter of the present invention is to use a hollow color paste box, which can hold the color paste inside, and the color paste flows slowly downwards naturally under the action of gravity, and flows to the color paste under the box. There is a transfer wheel and a squeegee mechanism at the opening below the color paste box. When the transfer printing wheel rotates at a certain speed and rotation angle under the control of the computer, the color paste on the printing wheel is scraped off by the squeegee blade, and the side is basically scraped off, while the outer peripheral surface is left with an appropriate thickness. Color paste.

The color paste box mechanism is installed in a transfer head mechanism, and the transfer head mechanism is installed on a multidirectional translational movement mechanism. The multi-directional translational movement mechanism can perform translational movement in three directions: horizontal X, vertical Y, and vertical Z. Among them, the longitudinal Y can realize the lateral translation movement with an included angle with the longitudinal Y under the action of the steering mechanism, and can perform translation movement in any direction and within a specified distance on the horizontal plane, and can reach any point in the plane work site.

In the transfer head mechanism, there is an angle deflection mechanism that makes the color paste box rotate on the horizontal plane, so that the rolling direction of the transfer wheel on the color paste box is the same as the moving direction of the entire color paste box, so that the printing transfer machine can The drawing of various patterns is completed in the combined translational movement of the three directions of horizontal X, vertical Y, and vertical Z.

The operation control of the transfer plotter in the present invention is accomplished by using a wireless network and remote control software between a fixed master computer and another controlled computer installed on the transfer plotter. There is a power supply device on the transfer plotter, so the working range of the transfer plotter is limited to the transmission and reception distance of the wireless network equipment, which can meet the drawing requirements of various large-scale patterns.

The speed and rotation angle of the transfer wheel on the color paste box are precisely controlled by the stepping motor driven by the computer. The linear speed of the surface is almost equal to the moving speed between the entire color paste box and the surface of the material, so that the transfer wheel can roll on the material surface with almost no friction, and the color paste on the outer periphery of the transfer wheel is transferred to the contact material. On the rolling track, the same thickness of color paste will be left on the rolling track to achieve a uniform coloring effect. The remaining color paste on the periphery of the transfer wheel is brought back to the inside of the color paste box under the continuous rotation of the transfer wheel, so that the color paste does not leak.

The color paste box mechanism can be easily loaded and unloaded from the opening in the transfer head, and the transfer wheels of the color paste box can be made into different widths to be suitable for transfer printing with different resolutions. The color paste box can contain color pastes of different colors, and can be adapted to printing of different colors.

Since the present invention can use fabric printing color paste and general viscous paint color paste, the color paste can be directly transferred to the surface of various materials suitable for coloring such as cloth, wood board, leather, road surface, etc. by using a computer for precise control. Compared with printing, there is no plate making process, no screen is used, and the pattern accuracy after transfer is high. Compared with thermal transfer printing technology, it does not require heating process, no pollution, and no health hazard to human body. Compared with inkjet technology, it can use general cloth and printing materials, and the cost is lower. Compared with plotters and manual drawing patterns, it can replace manual drawing of various precise and complex marking lines on the road to prompt text.

The present invention will be illustrated by preferred embodiments with reference to the accompanying drawings.

A transmission gear 293 and a synchronous wheel 300 are fixed on the transmission shaft 294 and rotate through two bearings 296 . A synchronous wheel 301 is fixed on the drive shaft 295 and rotates through two bearings 296 . When the drive shaft 295 rotates, it drives the fixed transfer wheel 309 to rotate. The outer peripheral surface of the transfer wheel 309 has a transfer wheel circumferential elastic layer 310, which is made of rubber or silica gel and has certain elasticity. When the color paste box transfer wheel transmission mechanism 25 transmits the rotation of the stepper motor 263 to the transmission gear 293 through the gear 260, the synchronous belt 302 drives the synchronous wheel 301 to rotate, and then drives the transfer wheel 309 to rotate synchronously. The function of the circumferential elastic layer 310 of the transfer wheel is to buffer the pressure of the transfer wheel on the colored surface, and to evenly spread the color paste.

As shown in Figures 15 and 28, the wide-stroke color paste box mechanism 28 can be placed at the opening 205 of the driven body support color paste box, and the color paste box placement protrusion 289 plays a positioning role, so that the wide-stroke color paste box mechanism 28 The transmission gear 293 and the transmission gear 260 on the color paste box transfer wheel transmission mechanism 25 can meet the correct meshing conditions, so that it is very convenient when changing the wide stroke color paste box mechanism 28.

As shown in Fig. 23 and Fig. 24, the scraping principle at the bottom of the wide-stroke color paste box mechanism 28 is: the position of the transfer wheel 309 and the circumferential elastic layer 310 of the transfer wheel is at the position of the return baffle 303 and the circumferential scraper of the transfer wheel 305 forms the inner and outer sides of the angled slurry leakage port. The inner part of the transfer wheel 309 and the circumferential elastic layer 310 of the transfer wheel can be in contact with the color paste, and the outer part cannot be in contact with the color paste. At the bottom of the color paste box mechanism 28 , a transfer wheel circumferential scraper 305 and a transfer wheel side scraper 308 are installed through bolts 312 , and a slurry return stopper 303 is installed on another slope. The side scraper 308 of the transfer wheel is not completely fixed by the bolt 312, leaving a certain gap, so that the side scraper 308 can be properly rotated around the bolt 312, and the rotation plane is parallel to the circumferential scraper 305 of the transfer wheel. The scraper spring 311 on the side of the transfer wheel pulls the two side scrapers 308 to the side of the transfer wheel 309 with a pulling force, and has an appropriate pressure on the side of the transfer wheel 309 . There is a proper gap between the circumferential scraper opening 306 of the transfer wheel and the circumferential elastic layer 310 of the transfer wheel. There is a proper gap between the opening 304 of the slurry return baffle and the circumferential elastic layer 310 of the transfer wheel, but the width of the gap is larger than the gap between the opening 306 and the circumferential elastic layer 310 of the transfer wheel. There is a proper gap between the slurry return baffle opening 304 and the two sides of the transfer wheel 309 . When the transfer wheel 309 is driven to rotate by the stepping motor, the direction of rotation is to make the elastic layer 310 turn from the side in contact with the color paste to the side not in contact with the color paste through the circumferential scraper opening 306 of the transfer wheel. The gap between the opening 306 and the circumferential elastic layer 310 of the transfer wheel makes the outer layer of the elastic layer 310 have a suitable thickness of color paste, and the color paste on the side of the transfer wheel 309 is removed under the action of the scraper 308 on the side of the transfer wheel. Or with a little color paste. When the transfer wheel 309 continues to rotate, after contacting with the surface of the substrate and transferring, it turns back to the side that can contact the color paste through the opening 304 of the slurry returning baffle. Because the gap between the slurry return baffle opening 304 and the circumferential elastic layer 310 of the transfer wheel is greater than the gap between the opening 306 and the circumferential elastic layer 310 of the transfer wheel, and at the same time, there is an appropriate gap between the two sides of the transfer wheel 309. gap. The width of the gap is adjustable, and its width range is: it can ensure that there is a color paste layer suitable for transfer thickness on the circumferential elastic layer 310 of the transfer wheel, and the color paste will not flow out arbitrarily. The remaining color paste on the circumferential elastic layer 310 of the transfer wheel and a little color paste left on the two sides of the transfer wheel 309 can be turned into the inside of the color paste box through the opening 304 of the return baffle. Through the continuous one-way rotation of the transfer wheel 309, the purpose of transferring the color paste to the surface of the printing object is achieved. Since the rotating speed of the transfer wheel 309 can be realized by controlling the stepping motor 253 by a computer, the surface linear velocity of the circumferential elastic layer 310 of the transfer wheel can be the same as or close to the moving speed between the entire transfer head and the printing material, so as to realize the printing accuracy. The color paste with uniform thickness is transferred on the material, and there is only the pressure perpendicular to the surface of the material during transfer between the surface of the circumferential elastic layer 310 of the transfer printing wheel and the printing material, and there is no friction parallel to the surface of the material. Material is transferred without wrinkling or slipping.

As shown in Fig. 25, Fig. 26, and Fig. 27, the fine-stroke color paste box mechanism 33 mainly consists of a color paste box 330, a color paste box support bearing seat 331, a color paste box support placement protrusion 332, a color paste box upper cover 333, and a color paste box. Pulp leakage round mouth 334 below the slurry box, transmission gear 335, transmission shaft 336,337, transfer printing oblique shaft 338, bevel gear 339,340,341, bearing 342, transfer printing ball 343 and form. Wherein the bevel gear 339 and the transmission gear 335 are fixed on the transmission shaft 336 , and the rotation is realized by two bearings 342 . The bevel gear 340 is fixed on the transmission shaft 337 and rotates through two bearings 342 . One end of the transfer oblique shaft 338 is connected to the transfer ball 343 , and the other end is connected to the bevel gear 341 , and the rotation is realized by the bearing 342 on the color paste box support bearing seat 331 . The three bevel gears 339, 340, 341 meet the correct meshing conditions. There is an appropriate gap between the transfer printing ball 343 and the slurry leaking round mouth 334 below the color paste box, so that the color paste inside the color paste box 330 can reach the upper end of the spherical surface of the transfer printing ball 343 without allowing the color paste to flow out arbitrarily. The distance between the center of the ball 343 of the transfer printing ball 343 and the axis of the slurry leakage circular opening 334 below the color paste box is not zero, but has a slight deviation. Therefore, the gap formed between the lower edge surface of the slurry leakage circular opening 334 below the color paste box and the transfer ball 343 is wide or narrow. When the transfer ball 343 is rotated, the surface of the transfer ball 343 turns out from a smaller gap, and then turns into a wider gap, so as to achieve the purpose of continuously transferring the color paste to the surface of the material in the form of fine strokes , and it will not cause the color paste to flow out randomly. When the transfer ball rotates, the surface linear speed is the same or close to the moving speed between the entire transfer head and the printing material. Since the transfer printing ball 343 can be made into a sufficiently small size, the contact area between it and the material is also very small, thereby realizing thinner strokes. There is an angle greater than zero between the transfer oblique axis 338 and the transfer material plane, so that only the transfer printing ball 343 connected to the transfer oblique axis 338 and the transfer material at the bottom of the fine stroke color paste box mechanism 33 have the smallest distance .

As shown in Figure 28, the outer dimension of the fine stroke color paste box mechanism 33 is the same as that of the wide stroke color paste box mechanism 28, which can be easily loaded and unloaded from the opening 205 below the driven main body support to realize the transfer printing required by different colors. When the fine-stroke color paste box mechanism 33 is installed at the opening 205, due to the positioning effect of the color paste box bracket placing protrusion 332, the transmission gear 335 on the fine-stroke color paste box mechanism 33 is connected with the color paste box transfer wheel transmission mechanism 25. The correct meshing condition can be satisfied between the transmission gears 260 .

As shown in FIG. 29, after the program starts to run, in step 1001, the type and quantity of colors to be transferred in the image file are determined. In step 1002, specify one of the colors to be transferred, and then go to step 1003. In step 1003, when a color is specified, no matter how complicated the pattern is, an appropriate program can be compiled to obtain a set of plane coordinate sequences of points according to the stroke width of the transfer wheel, that is, a single pattern can be decomposed into several Sub-strokes are respectively transferred to the effect of cumulative effect, and the plane coordinate sequence of a group of points represents a single stroke from pen-down to pen-start. In step 1004, according to the plane coordinate sequence of each group of points, the number of pulse signals that the vertical and horizontal motors need to rotate is calculated from the coordinates of two adjacent points, and the connection line between the two points and the initial position of the transfer head are calculated. The amount of angular deflection between the angles, and then calculate the number of pulses that the stepper motor 210 needs to run for angular deflection, and the number of pulses that the transfer wheel needs to rotate can be calculated from the straight-line distance between two points. Thus, the sequence of stepping motor pulse numbers required for completing all single strokes is obtained in the vertical direction, horizontal direction, angular deflection, and transfer wheel. After the calculation is completed, enter the transfer program. In step 1005, it is judged in step 1005 that in the pulse sequence of each motor operation of a group of points to be processed, whether the current pulse sequence to be processed belongs to the starting point, if it is the starting point, then enter step 1006, even if the vertical stepping motor 146, horizontal stepping The motor 155 and the angle deflection stepping motor 210 perform interpolation operation, so that the transfer head reaches the starting point of the transfer, and then run step 1007, driven by the rotation of the vertical stepping motor on the vertical motion mechanism 16, the transfer head is moved to the top of the transfer head. The surface of the outer peripheral surface 310 of the transfer wheel reaches the surface of the substrate, that is, the pen-down action. Then enter step 1008, according to the pulse sequence of each point, the vertical stepper motor 146, the horizontal stepper motor 155, the angular deflection stepper motor 210 and the transfer wheel stepper motor 253 run synchronously with interpolation. If it is judged in step 1005 that it is not the starting point, repeat step 1008. Step 1008 will check whether there is an instruction to interrupt the running every time the pulse sequence of a point is completed, and if so, step 1011 will inquire whether the program needs to be terminated. If yes in step 1011, then exit the transfer process, if no, then enter step 1010, check whether the end point of this group of coordinate sequences is reached, if no, then return to step 1008, if yes, then execute step 1012, That is, driven by the rotation of the vertical stepping motor 160 , the surface of the outer peripheral surface 310 of the transfer wheel on the transfer head is separated from the surface of the substrate, that is, the action of raising the pen. Then enter step 1013, check whether there are unprocessed coordinate sequence groups. If yes, then return to step 1005, if no, it indicates that the transfer of the specified color is completed, and then enter step 1014 to check whether to start transferring the next color. If yes, return to step 1002, if no, end the transfer procedure. After the work of the above-mentioned main process, the computer can instruct the motion mechanism where each stepping motor is located to complete various actions, thereby completing the transfer task.

As shown in Figure 30, it is a flow chart of the computer controlling the stepper motor to realize lateral movement. After the program starts, enter step 2001, that is, the steering stepper motor 130 continues to rotate, and stops when the motion direction of the road wheels 145B is perpendicular to the lateral motion direction. Enter step 2002, input the deflection angle between the current point and the starting point to be reached, enter step 2003, turn to the stepper motor 130 to rotate an angle, enter step 2004, input the linear distance to be moved, enter step 2005, stepper motor 140 Rotate to drive the entire transfer plotter to the predetermined starting point. Enter step 2006, check whether the current starting point is suitable. If not, then get back to step 2002, and re-locate the starting point, if yes, then enter step 2007, even if the steering motor 130 is reset, and arrives at a position perpendicular to the lateral movement direction, then the program ends.
