[0030] Working principle: When in use, the material is first passed over the receiving roller 4, then between two drive tubes 8, then under the drive roller 6, then between two other drive tubes 8, and simultaneously over one of the processing rollers 19. The material then passes between multiple moving nozzles 33 on one of the moving components and on the other moving component. The material then passes under another processing roller 19 and is wound around the external winding device.

[0031] Then, start the connecting motor 12 on the drive assembly. The connecting motor 12 drives the connecting gear 13 to rotate. Then, the connecting gear 13 drives the two drive gears 9 to rotate. The drive gears 9 then drive the drive tube 8 to rotate, so that the multiple cleaning bristles on the drive tube 8 rotate and clean the upper and lower surfaces of the material.

[0032] Simultaneously, the water pump 14 on the water pumping assembly is started, and the water pump 14 drives the first branch pipe 15 to draw water from the inside of the housing 2, so that the water passes through the first branch pipe 15 and the second branch pipe 16 and is discharged into the U-shaped pipe 17. Then, the water passes through the U-shaped pipe 17 and is discharged into the corresponding drive pipe 8, and then is discharged from the multiple drive nozzles 10 on the drive pipe 8, so as to clean the upper and lower surfaces of the material after rinsing.

[0033] Then, the external winding device is started to wind up the material. Next, the drive motor 5 is started, which drives the drive roller 6 to rotate, so that the drive roller 6 assists in the transmission of the material. Then, the movable motor 24 is started, which drives the movable worm 26 on the movable rod 25 to rotate. Then, the movable worm 26 drives the corresponding movable worm wheel 21 to rotate.

[0035] Then, the adjusting motor 39 is started, which drives the adjusting wheel 40 to rotate.
