Description

Technical Field

[0001] The present disclosure relates to the technical field of pole piece production, and in particular to a roller cleaning device and pole piece production rolling equipment. Background Art

[0002] During the production process of pole pieces, rollers are usually used to roll and flatten the pole pieces. During the rolling process, the coating material of the pole piece tends to adhere to the rolling surface of the roller. The coating material adhered to the rolling surface of the roller is referred to as "attachments" below. If the rolling surface carries attachments when rolling the pole piece, the roller will press the attachments into the pole piece surface, resulting in the problem of "pole piece inclusion". The subsequent process will remove the pole piece with the "pole piece inclusion" problem, resulting in pole piece waste.

[0003] Existing technologies such as patent CN218925411U2 propose a wiping roller device for electrode coating, including a wiping roller mechanism, a spray mechanism and a scraper mechanism, and the wiping roller mechanism and the scraper mechanism are arranged in sequence along the movement direction of the steel roller; the wiping roller mechanism includes a non-woven fabric, and the non-woven fabric moves from the non-woven fabric unwinding roller to the non-woven fabric winding roller; when the non-woven fabric is in relative contact with the surface of the steel roller, the non-woven fabric and the steel roller run in the same direction, so that the wiping roller mechanism and the scraper mechanism can jointly clean the surface of the steel roller; the non-woven fabric is arranged between the spray mechanism and the steel roller, so that the spray mechanism can first spray the cleaning agent onto the non-woven fabric to wet it, and then the wetted non-woven fabric can abut against the surface of the steel roller to reduce the adhesion between the attachment and the surface of the steel roller, and at the same time avoid the spray mechanism from spraying the cleaning agent directly onto the surface of the steel roller, resulting in excessive use of the cleaning agent, so that the cleaning effect of the wiping roller device is better.

[0004] However, during the working process of the above-mentioned wiping roller device, since the positions of the wiping roller mechanism and the spray mechanism are constant, when the wiping roller mechanism is too far away from the surface of the steel roller, the tension of the non-woven fabric is too small, thereby making the cleaning effect of the wiping roller device poor; when the wiping roller mechanism is too close to the surface of the steel roller, the tension of the non-woven fabric is too large, thereby making the friction between the non-woven fabric and the surface of the steel roller too large, causing the non-woven fabric to be pulled away by the steel roller, greatly reducing the cleaning efficiency of the roller; at the same time, when the spray mechanism sprays the non-woven fabric in contact with the surface of the steel roller, the wetting uniformity of the non-woven fabric is poor, and the wetting uniformity of the non-woven fabric on the surface of the steel rod after being wetted is also poor, thereby causing the local presence of attachments on the rolling surface and high adhesion to the rolling surface, especially in the area where the rolling surface is not fully wetted, resulting in poor cleaning effect of the rolling surface by the roller cleaning device, resulting in waste of pole pieces.

[0059] The present disclosure also provides a pole piece production rolling device, comprising the roller cleaning device 10 described in any of the above embodiments.

[0060] Compared with the prior art, the present disclosure has at least the following advantages:

[0061] 1. The above-mentioned electrode production rolling equipment, since the roller 500 is rotatably connected to the frame 100, the scrubbing assembly 210 is arranged on the frame 100, and one side of the cleaning end of the scrubbing assembly 210 abuts against the rolling surface of the roller 500 to clean the rolling surface of the roller 500. The cleaning end of the scrubbing assembly 210 is parallel to the axial length of the roller 500 and is equal to the axial length of the roller 500. The spray mechanism 300 includes a horizontal drive assembly 320 and a spray assembly 310. The horizontal drive assembly 320 is arranged on the frame 100, and the power output end of the horizontal drive assembly 320 is connected to the spray assembly 310. The cleaning end of the scrubbing assembly 210 is connected to the cleaning end of the scrubbing assembly 210 to drive the spray assembly 310 to reciprocate in an axial direction parallel to the roller 500. The spray port of the spray assembly 310 is arranged toward the other side of the cleaning end of the scrubbing assembly 210, so that the spray assembly 310 can spray and moisten the cleaning end of the scrubbing assembly 210 evenly, so that the moistened cleaning end of the scrubbing assembly 210 can evenly moisten the rolling surface by abutting against the rolling surface, reduce the adhesion between the attachment and the rolling surface, improve the cleaning effect of the scrubbing assembly 210 on the rolling surface, and thus greatly improve the production efficiency and production quality of the electrode.

[0062] 2. Since the pressure regulating mechanism 400 includes a telescopic drive component 410 and a connecting frame component 420, the telescopic drive component 410 is arranged on the frame 100, and the power output end of the telescopic drive component 410 is fixedly connected to the connecting frame component 420 to drive the connecting frame component 420 to move relatively closer or farther away from the roller 500, and the cleaning end of the scrubbing component 210 is slidably connected to the connecting frame component 420, so that the telescopic drive component 410 can adjust the distance between the cleaning end of the scrubbing component 210 and the rolling surface of the roller 500, so that the pressure regulating mechanism 400 can control the pressure between the cleaning end of the scrubbing component 210 and the rolling surface of the roller 500, thereby avoiding the problem of low cleaning efficiency and poor cleaning effect of the roller cleaning device 10 on the roller 500 due to the distance between the cleaning end of the scrubbing component 210 and the rolling surface being too far or too close, further improving the cleaning effect and cleaning efficiency of the scrubbing component 210 on the rolling surface, thereby further improving the production efficiency and production quality of the electrode.

[0063] The above-described embodiments merely represent several implementation methods of the present disclosure. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the scope of the present disclosure, all of which fall within the scope of protection of the present disclosure. Therefore, the scope of protection of the disclosed patent shall be determined by the appended claims.
