During the production and processing of some lightbox fabrics, an environmentally friendly polyurethane coating is added to the surface of the fabric using coating equipment to improve the color stability of the fabric.
[0003] Common fabric coating equipment uses rotating coating rollers to coat the fabric surface. However, when the fabric surface is not smooth enough, uneven coating may occur during the coating process, which will affect the quality of the fabric coating process. In addition, some coating equipment uses simultaneous drying from the top and bottom. During the drying process, the coating on the fabric may drip onto the bottom drying component, affecting the drying effect.

The output end of 6 is respectively equipped with a first drying pipe 17 and a second drying pipe 18. The top of the drying tank 20 is equipped with a third guide roller 15 on both sides. The drying tank 20 is equipped with three sets of fourth guide rollers 19 inside. The bottom right side of the processing seat 1 is equipped with a discharge pipe 21. The top of the processing seat 1 is provided with a reserved groove 9. The top of the reserved groove 9 is equipped with a fixed frame 10. The top of the fixed frame 10 is equipped with a suction pump 12. The input end of the suction pump 12 is equipped with a suction pipe 11. The inside of the fixed frame 10 is equipped with a spray layer assembly 13 on both sides. The top of the spray layer assembly 13 is equipped with a connecting pipe 25. The bottom of the reserved groove 9 is equipped with a guide channel 14.
[0025] The extraction pipe 11 is installed inside the paint tank 3, the connecting pipe 25 is connected to the output end of the extraction pump 12, the guide channel 14 is connected to the interior of the reserved tank 9 and the paint tank 3 respectively, and the spraying assembly 13 is provided in two sets, each of which is equipped with an inclined nozzle.
[0026] Specifically, such as Figure 1 and Figure 4 As shown, after the fabric is soaked in the coating tank 3, it enters the fixed frame 10 through the first guide roller 7. The extraction pump 12 on the fixed frame 10 can pump the coating from the coating tank 3 to the spraying assembly 13. The spraying assembly 13 can spray the fabric on both sides fully and evenly. After spraying, the coating uniformity is improved by the transmission of the third guide roller 15. Excess coating during spraying can fall into the reserved groove 9 and then flow back into the coating tank 3 through the guide channel 14.
[0027] Two sets of the first drying pipe 17 and the second drying pipe 18 are provided. The second drying pipe 18 is installed on both sides inside the drying tank 20. The discharge pipe 2 is connected to the paint tank 3, and the discharge pipe 21 is connected to the drying tank 20.
[0028] Specifically, such as Figure 1 and Figure 3As shown, the fourth guide roller 19 inside the drying tank 20 can guide the fabric in a W-shape, which prolongs the time the fabric moves inside the drying tank 20. Moreover, the first drying tube 17 and the second drying tube 18 dry both sides of the fabric at the same time. The drying tubes are in a vertical state to prevent the paint on the fabric from dripping into the drying port.
[0029] The front and rear ends of the support frame 4 are fixedly connected to the limiting slider 22, the limiting slider 22 is provided with the fixing bolt 23, the mounting frame 6 is provided with the limiting groove 24, the limiting slider 22 is embedded in the limiting groove 24, and the fixing bolt 23 passes through the limiting slider 22 and is embedded in the mounting frame 6.
[0030] Specifically, such as Figure 1 and Figure 2 As shown, when the fabric moves inside the paint tank 3, the limiting roller 5 can keep the fabric in full contact with the paint. The tightness of the fit between the limiting roller 5 and the fabric can be adjusted. When adjusting, first unscrew the fixing bolt 23, then move the support frame 4. The limiting slider 22 on the support frame 4 slides inside the limiting groove 24, and then the fixing bolt 23 can be used to fix it.
[0031] Working Principle: In use, the first guide roller 7 guides the fabric into the paint tank 3. As the fabric moves within the paint tank 3, the limiting roller 5 ensures the fabric remains in full contact with the paint. After the fabric is immersed in the paint tank 3 and coated, it enters the fixed frame 10 via the first guide roller 7. The extraction pump 12 on the fixed frame 10 draws the paint from the paint tank 3 into the spraying assembly 13. The spraying assembly 13 sprays the fabric thoroughly and evenly on both sides. After spraying, the third guide roller 15 further enhances the uniformity of the paint. Excess paint during spraying can fall into the reserved groove 9 and then flow back into the paint tank 3 through the guide channel 14. The coated fabric can then pass through the drying tank 20. The fourth guide roller 19 inside the drying tank 20 can guide the fabric in a W-shape, which prolongs the time the fabric moves inside the drying tank 20. Moreover, both sides of the fabric are dried simultaneously through the first drying pipe 17 and the second drying pipe 18. The drying pipes are in a vertical position to prevent paint on the fabric from dripping into the drying port. This structure achieves the function of facilitating thorough drying.
