[0016] 2、In the present application, the pole piece and the shell are pressed by the rolling rod and fall onto the surface of the rolling rod under the action of their own gravity, the rack moves upward to drive the gear to rotate, the rotation of the gear drives the rolling rod to rotate, the rotation of the rolling rod can ensure that the material continuously enters the processing equipment, and the pole piece and the shell will not be affected by the ionized liquid or the magnet to adhere or be stuck at the feeding point, which helps to maintain the continuity of production, avoids shutdown and interruption of production, means that more materials can be processed in a shorter time, thereby improving production efficiency and yield.

[0018] 4. In this invention, the sliding plate moves downward to squeeze the two swing plates.

The screening device includes a roller 31, a conveyor belt 32, a baffle 33, a magnet 34, a rotating column 35, a rotating block 36, and a vibrating plate 37. The magnet 34 in the conveying groove at the bottom of the conveyor belt 32 attracts the outer shell of the lithium battery electrode. The conveyor belt 32 drives the electrode attracted by the magnet 34 to move closer to the housing 2. Non-magnetic metal impurities mixed in the outer shell of the lithium battery electrode are retained at the feed point of the conveyor belt 32 under the action of their own gravity. The vibration of the conveyor belt 32 shakes the non-magnetic metal impurities adhering to the surface of the conveyor belt 32 off to the feed point of the conveyor belt 32. A motor is fixedly installed on the surface of the placement rack 1, and the roller... Roller 31 is fixedly installed at the motor output end. Conveyor belt 32 is set on the surface of roller 31.

The crushing device 41 is rotatably installed in the inner wall of the shell 2. The transmission rod 42 is fixedly installed on the surface of the crushing device 41. The rack 44 is slidably installed in the inner wall of the shell 2. The contact rod 43 is fixedly installed at the bottom of the rack 44. The rolling rod 45 is rotatably installed in the inner wall of the shell 2. The gear 46 is fixedly installed on the surface of the rolling rod 45. The rotation of the rolling rod 45 can ensure that the material continuously enters the processing equipment. The pole piece and the shell will not be affected by the ionized liquid or the magnet 34 to adhere or be stuck at the feeding position, which helps to maintain the continuity of production, avoids shutdown and production interruption, means that more materials can be processed in a shorter time, thereby improving the production efficiency and yield.
