[0023] Furthermore, the electrode dust removal device 18 includes a conveyor belt 10, a cleaning plate 11 and an active roller 13. The front side surface of the mounting plate 2 is rotatably connected to a support roller corresponding to the lower side of the slitting machine 9. The front side surface of the mounting plate 2 is rotatably connected to one end of the support roller away from the motor 6, and three equidistantly arranged follower rollers 4 are rotatably connected. The other end of the front side surface of the mounting plate 2 is rotatably connected to two active rollers 13. The active roller 13 and the three follower rollers 4 above are transmission-connected to the conveyor belt 10. The front side surface of the mounting plate 2 is fixedly connected to the upper side of the conveyor belt 10. The conveyor belt 10 is driven to rotate by the follower roller 4 and the active roller 13, and the surface of the electrode can be cleaned by the cleaning plate 11.

[0024] Furthermore, the lower end of the cleaning plate 11 is provided with sponge blocks arranged at equal intervals, which can clean the debris and dust on the surface of the pole piece multiple times, and leave space for temporary storage of the squeezed debris.

[0025] Furthermore, the conveyor belt 10 is provided with debris leakage holes 14 arranged in a matrix, and the debris leakage holes 14 penetrate the upper and lower surfaces of the conveyor belt 10. When the debris leakage holes 14 rotate with the conveyor belt 10, the debris temporarily stored can flow to the bottom.

[0026] Furthermore, the dust storage device 8 includes a debris trough 12, a dust collecting box body 15, an suction fan 16 and a collecting drawer 17. The upper surface of the support bracket 1 is provided with a debris trough 12 corresponding to the lower part of the active roller 13, and the debris trough 12 runs through the upper and lower surfaces of the support bracket 1. The lower surface of the support bracket 1 is fixedly connected with a dust collecting box body 15 corresponding to the lower part of the debris trough 12.

[0028] Working principle: When the device is needed to slit the pole pieces of lithium batteries, the power is turned on, and the pole pieces are fed through the feeding device 3 and four follower rollers 4 to the middle of the slitting machine 9 and the support roller for cutting. The debris formed by cutting falls directly downward onto 19, and falls into the debris groove 12 under the influence of its own gravity. The other part of the debris follows the pole piece and falls onto the conveyor crawler 10. After the pole piece is cut into small pieces, it falls onto the conveyor crawler 10. The conveyor crawler 10 is driven to rotate by the active roller 13 and the upper follower roller 4 to convey the pole piece and the debris falling onto the conveyor crawler 10. When the cut pole piece enters the conveyor crawler 10 and the cleaning plate 11, the conveyor crawler 10 is rotated and the pole piece and the debris falling onto the conveyor crawler 10 are conveyed. During the movement, the sponge block at the bottom of the cleaning plate 11 will clean the surface of the electrode and block the debris falling onto the conveyor belt 10. During the movement of the conveyor belt 10, the blocked debris falls into the debris trough 12 through the debris leakage hole 14 for collection; the debris falling into the debris trough 12 will fall into the collecting drawer 17 under the attraction of the suction fan 16, and the suction force of the suction fan 16 will also absorb the smaller cutting dust generated by cutting in the dust box 7, further reducing the impact of dust and impurities generated by cutting the electrode on the environment, and the impurities or debris collected by the collecting drawer 17 can be recycled for a second time after processing, saving production costs.
