[0002] During the processing of woven bags, the surface of the woven bags needs to be coated. By spraying the paint in a quantitative manner, it can be ensured that the coating is uniform and does not overflow or leak, thus avoiding waste of paint. This is of great significance to improving the production efficiency and quality of woven bags. Usually, when using a coating roller in conjunction with an ink supply device to coat the woven bags, due to the certain diffusivity of the film material, when the coating roller rotates, the film material moves downward, which will cause the uniformity of the coating to deteriorate.

At the same time, while standardizing, raw materials are saved and the quality of the coating is improved. By setting the roller at the bottom end of the slide rod, the friction between the slide rod and the eccentric cam is reduced, the service life of the device is increased, and the cost of use is reduced. In this process, when the film material falls on the coating roller, it will move downward due to gravity, resulting in poor uniformity of the coating.

[0004] Therefore, a coating device for a woven bag production line with a quantitative spraying function is proposed to solve the problem that when the film material falls on the coating roller during this process, it will move downward due to gravity, resulting in poor uniformity of the coating.

When the roller 4 rotates, the pressure roller 6 can provide pressure to squeeze out the excess paint adsorbed by the sponge cover 5, so that the paint passes through the leakage groove on the bottom side of the guide plate 8 and then falls into the sealing cover 18 through the circular hole 19 to achieve recycling. The bottom side of the sponge cover 5 is in contact with the pressure roller 6, and the bottom side of the pressure roller 6 is fixedly connected to the scraper 7. The bottom end of the scraper 7 is fixedly connected to the guide plate 8. The bottom side of the scraper 7 is provided with a leakage groove. The fixed box 1 is located at the lowest point of the guide plate 8 and is provided with a circular hole 19. One side of the guide plate 8 is in contact with the adsorption roller 9.
