[0045] Working principle:

[0046] The relative positions of the upper guide roller 7 and the lower guide roller 10 and the rolling roller 2 are adjusted by the set screws on the upper guide roller side plate top block 75 and the lower guide roller side plate top block 10, so that the non-woven fabric is wrapped on the surface of the rolling roller.

[0047] Then, the sliding plate 912 is pushed by the air cylinder 94, and then the pressing plate 913 is pushed out to tightly press the non-woven fabric on the surface of the rolling roller 2. The pressing plate 913 is a structure with a rubber-coated sheet metal main body, and the part in contact with the rolling roller is made of soft rubber material to avoid scratching the roller surface. The water spraying device 8 sprays the solvent on the non-woven fabric to wet the non-woven fabric. During the rotation of the rolling roller 2, the residual carbon powder on the surface is wiped off with the wet non-woven fabric. After running for a period of time, the pressing plate 913 is retracted by the air cylinder 94. The non-woven fabric roll 157 starts to wind up under the drive of the motor 1510. After the soiled non-woven fabric is taken away, the clean non-woven fabric turns to the position of the pressing plate. The pressing plate 913 is pushed out again by the air cylinder 94 to tightly press the non-woven fabric on the surface of the rolling roller 2, and the wiping roller action is repeated. The residual sewage on the roller surface is scraped off by the scraper 11 and flows into the water receiving box 13 for discharge. The air blowing pipe 12 blows air on the roller surface at the same time to dry the roller surface, and the dry wipe 14 further wipes off the remaining water streaks to ensure that there are no water streaks remaining on the roller surface and will not affect the pole piece.

[0048] The upper guard plate 51 is a structure with an aluminum alloy frame wrapped by a transparent PC board, which can not only prevent the water mist from spreading everywhere, but also facilitate observing the water spraying situation of the water spraying device 8. The support rod 6 plays a supporting role for the non-woven fabric to prevent the non-woven fabric from sagging and contacting and interfering with the water spraying device 8, causing damage to the non-woven fabric.

[0049] A detection switch 73 is arranged in the upper guide roller device 7, and a detection iron sheet is arranged on the upper guide roller 71. Through the detection of the detection switch 73, the number of rotations of the upper guide roller 71 during the winding of the non-woven fabric is counted and controlled, so as to control the winding speed and winding length of the non-woven fabric each time, ensure that the winding speed of the non-woven fabric is uniform and the winding length is the same each time, and avoid the fluctuation of the winding speed and winding length of the non-woven fabric due to the change of the diameter of the non-woven fabric roll 157 during winding.

[0050] A cylinder fixing plate top block 91 and a pressing plate upper limit seat top block 98 are arranged in the pressing plate assembly 9 to adjust the relative position of the pressing plate 913 and ensure the degree of fit between the pressing plate 913 and the roller surface. The upper limit seat of the pressing plate 99 is a split structure and is connected together by a five-star handle 911. When the pressing plate 913 is disassembled and assembled, the five-star handle 911 is removed, and the upper limit seat of the pressing plate 99 can be separated, which is convenient for disassembling and assembling the pressing plate 913.

[0051] In the unwinding and rewinding assembly 15, a trapezoidal lead screw 152 and a rotary chuck 156 are used to fix the non-woven fabric roll 157. A clamping groove is provided on the barrel of the non-woven fabric roll 157, and a clamping block is provided on the rotary chuck 156, which is matched with the clamping groove on the barrel of the non-woven fabric roll 157 for fixation. The motor 1510 drives the rewinding, and the magnetic powder brake 1511 gives a certain braking force to the non-woven fabric to prevent the non-woven fabric from loosening and sagging during rewinding.

[0052] In this patent, a detection switch is provided in the upper guide roller device to control the rewinding speed and rewinding length of the non-woven fabric each time, ensuring that the rewinding speed of the non-woven fabric is uniform and the rewinding length is the same each time, and avoiding fluctuations in the rewinding speed and rewinding length of the non-woven fabric due to changes in the diameter of the non-woven fabric roll during rewinding.
