The winding mechanism 8 is located on the side of the drying chamber 7 away from the cloth feed end.

[0045] The implementation principle of a textile fabric coating device in the embodiment of the present application is as follows:

[0046] During work, the operator lays the cloth on the top of the cloth guide roller 11, and lets the cloth pass through the coating space formed between the two groups of coating components 21, the scraping space formed between the two scrapers 31 and the drying chamber 7 in sequence, and finally the cloth is rolled up together by the rolling mechanism 8.

[0047] During the movement of the cloth, the operator opens the nozzle 211 and starts the pressure pump 223 through the control box 222, so that the pressure in the storage box 221 increases, and the paint enters the paint box 212 through the feed pipe 224 and then reaches the nozzle 211, and then the nozzle 211 sprays the paint onto the surface of the cloth; when the cloth only needs to be coated on one side, the operator only needs to open the nozzle 211 in one group of paint components 21.

[0048] When the thickness of the cloth changes or the distance between the nozzle 211 and the cloth needs to be adjusted, the operator starts the two first motors 411 at the same time, and the rotation of the output shaft of the first motor 411 drives the first screw rod 412 to rotate. The rotation of the first screw rod 412 drives the two paint boxes 212 to move closer to or away from each other, and the nozzles 211 on the two paint boxes 212 can move closer to or away from each other, thereby adjusting the distance between the nozzle 211 and the cloth.

[0049] During the movement of the cloth, the two scrapers 31 always contact the surface of the cloth to smooth the paint on the cloth. The cloth treated by the scrapers 31 enters the drying chamber 7 for drying. After the drying of the cloth is completed, the winding mechanism 8 winds up the cloth.

[0050] After long-term operation, paint may accumulate on the scraper 31. After the coated cloth is rolled up, the operator starts the second motor 62. The rotation of the output shaft of the second motor 62 drives the second screw 63 to rotate. The rotation of the second screw 63 drives the scraper block 61 to move. During the movement of the scraper block 61, it always contacts the side wall of the scraper 31 to scrape off the paint accumulated on the scraper 31, and the scraped paint falls into the material receiving box 67 for collection.

[0051] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
