The output end of the reduction motor 32 will drive the coating roller 28 to rotate and apply glue to the surface of the PVC film.

[0032] When the position of the coating roller 28 needs to be adjusted, the second motor 15 is controlled to start, and the output end of the second motor 15 drives the screw 16 to rotate. The rotation of the screw 16 drives the two threaded blocks 17 and the two U-shaped plates 18 to approach each other. The two U-shaped plates 18 approach each other, thereby driving the two rotating plates 19 to rotate and drive the reduction motor 32, the two connecting plates 20, the adjustment plate 21, the storage box 27 and the coating roller 28 to move upward and compress the telescopic rod 31, so that the height of the coating roller 28 can be quickly adjusted according to needs, thereby improving work efficiency and reducing labor costs.

[0033] By controlling and starting the electric telescopic rod 7, the output end of the electric telescopic rod 7 will drive the sliding block 8, the tensioning roller 9 and the cleaning roller 10 to move upward, thereby adjusting the tightness of the PVC film, and the cleaning roller 10 can be used to clean the dust on the PVC film to avoid affecting the glue coating.

[0034] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
