[0002] Flocking is a common surface treatment process that creates a velvety effect on fabric surfaces by applying an adhesive and adsorbing short fibers. Currently, flocking is widely used in clothing, home decoration, and automotive interiors. As market demands for flocked product quality increase, uniform and efficient adhesive coating has become one of the key technical challenges. Traditional flocking adhesive application methods include spraying, scraping, and dipping, but these methods have certain limitations in terms of coating uniformity, adhesive control, and production efficiency.

[0003] However, in existing roller coating equipment, it has been found that the adhesive is usually applied to the fabric surface by scraping with a scraper to achieve adhesion. This coating method not only has poor coating uniformity, but also easily causes scratches on the fabric, thus affecting the subsequent flocking effect. Utility Model Content

[0022] This roller coating device for fabric flocking, comprising an electric push rod, pressure sensor, threaded rod, and lifting seat, first activates a first motor to rotate the threaded rod. The threaded rod, connected to the lifting seat, causes the lifting seat to lower a second motor, a first limit sleeve, and the coating roller, thus adjusting the distance between the coating roller and the support roller. During coating, the pressure sensor detects the pressure, and then the electric push rod is activated to raise and lower the mounting frame, making the height of the support roller adjustable. This allows the device to adjust the distance and pressure between the support roller and the coating roller, thus... Improving coating uniformity can significantly enhance the flocking effect. When the surface of the coating roller is severely worn, the corresponding fixing bolts are removed, and the connection between the connector and the lifting seat is released. This allows the connector to move the second limiting sleeve. At this time, the connection between the second limiting sleeve and the coating roller is released, allowing the coating roller to move laterally. Then, the right end of the coating roller is disconnected from the first limiting sleeve, thus disassembling the coating roller. This facilitates the disassembly of severely worn coating rollers, making it easier to inspect and replace them, and also facilitates the replacement of coating rollers of different specifications.

[0035] Please see Figure 4 and Figure 5The inner wall of the lifting seat 9 is fitted with a second limiting sleeve 19. A connecting piece 20 is rotatably connected to the outer surface of the second limiting sleeve 19. Two fixing bolts 21 are fixedly installed between the connecting piece 20 and the lifting seat 9. The second limiting sleeve 19 is fitted onto the inner wall of the lifting seat 9 to allow it to be disassembled. The connecting piece 20 is installed on the outer surface of the second limiting sleeve 19 and is rotatably connected. By installing two fixing bolts 21 between the connecting piece 20 and the lifting seat 9, the connecting piece 20 and the second limiting sleeve 19 can be fixed, thus facilitating the disassembly of the second limiting sleeve 19. The second limiting sleeve 19 is connected to both the coating roller 12 and the first limiting sleeve 11 via keyways, allowing the second motor 10 to drive the coating roller 12 to rotate through the first limiting sleeve 11, while also facilitating the disassembly of the coating roller 12 for inspection and replacement.

[0036] The implementation principle of this application embodiment is as follows: When applying adhesive to the fabric, the fabric is first placed between the support roller 4 and the coating roller 12. Then, the first motor 7 is started to rotate the threaded rod 8. Through the connection between the threaded rod 8 and the lifting seat 9, the lifting seat 9, the second motor 10, and the first limiting sleeve 11 are lowered. Through the connection between the guide rod 15 and the lifting seat 9, the lifting seat 9 is raised and lowered stably. At this time, the distance between the coating roller 12 and the support roller 4 is adjusted. During the fabric transfer process, the second motor 10 is started to drive the first limiting sleeve 11 to rotate, thereby causing the coating roller 12 and the second limiting sleeve 19 to rotate. The adhesive is transferred through the hose 24 and the connecting pipe 23, and finally discharged through the adhesive outlet 22. The adhesive falls on the surface of the coating roller 12 and in the groove 18. The coating is completed through the cooperation of the support roller 4 and the coating roller 12. During the coating process, the pressure sensor 5... The device monitors pressure changes in real time and raises and lowers the mounting frame 3 and support roller 4 via the electric push rod 2, thereby adjusting the pressure between the support roller 4 and the coating roller 12. By adjusting the distance and pressure between the support roller 4 and the coating roller 12, the coating uniformity is improved, which in turn significantly enhances the flocking effect. When the surface of the coating roller 12 shows severe wear or a different specification of coating roller 12 needs to be replaced, the corresponding fixing bolt 21 is removed, the connection between the connector 20 and the lifting seat 9 is released, and then the connector 20 is moved to move the second limiting sleeve 19, releasing the connection between the second limiting sleeve 19 and the coating roller 12. Then, the right end of the coating roller 12 is disconnected from the first limiting sleeve 11, thus disassembling the coating roller 12. This device facilitates the maintenance and replacement of the coating roller 12 and also makes it easy to replace coating rollers 12 of different specifications.
