[0022] The screening structure 4 includes a bellows cover 41, an installation shell 42, a screening plate 43, a first motor 44, a cam 45, an installation plate 46 and a spring 47.

When the first motor 44 is turned on, the output shaft of the first motor 44 will drive the upper cam 45 to rotate. The rotating cam 45 will collide with the installation shell 42, causing the installation shell 42 to move forward. The lower bellows cover 41 will be stretched. After the spring 47 is compressed, it will rebound. The installation shell 42 is pushed back to its original position by the spring 47. Through the rotation of the cam 45 and the rebound of the spring 47, the installation shell 42 sways back and forth to perform vibrating screening treatment on the battery materials.

[0023] The rotating structure 8 includes a second motor 81, a sprocket 82, a toothed ring 83 and a chain 84. The second motor 81 is fixed to the top of the mounting table 7. The sprocket 82 is fixed to the right end of the output shaft of the second motor 81. The toothed ring 83 is fixed to the left side of the surface of the screening cylinder 6.

Brackets 13 are fixed to the left and right sides of the inner wall of the fixing frame 1, and guide wheels 14 are rotatably connected to the front and rear of the top of the bracket 13. Guide frames 15 are fixed to the left and right sides of the surface of the screening cylinder 6, and the guide wheels 14 are located inside the guide frames 15 and are in rolling connection with the inner walls of the guide frames 15. After the preliminarily screened battery materials enter the inside of the screening cylinder 6, the staff turns on the second motor 81, so that the output shaft of the second motor 81 drives the sprocket 82 to rotate, causing the chain 84 to start moving. The chain 84 drives the toothed ring 83 to rotate, so that the entire screening cylinder 6 rotates. The guide wheels 14 at the bottom of the screening cylinder 6 will roll inside the guide frames 15, thereby guiding the screening cylinder 6 and increasing the stability of the screening cylinder 6 during rotation. Thus, while the screening cylinder 6 re-screens the battery materials, it conveys the battery materials to the right side.

The connecting table 104 is fixed to the front side of the bottom of the inner wall of the fixing plate 101, and the threaded rod 103 passes through the connecting table 104 and is rotatably connected to the connecting table 104. The connecting frame 105 is arranged below the fixing plate 101, and the rear side of the top of the connecting frame 105 is movably connected to the fixing plate 101. The threaded rod 103 passes through the connecting frame 105 and is threadedly connected to the connecting frame 105. The flapping block 106 is arranged below the connecting frame 105, and the rear side of the bottom of the connecting frame 105 is slidably connected to the flapping block 106. Guide strips 16 are fixed to the left and right sides of the front of the bottom of the fixing plate 101 and the left and right sides of the front of the top of the flapping block 106. Guide blocks 17 are fixed to the front of the upper and lower sides of the connecting frame 105, and the guide strips 16 pass through the guide blocks 17 and are slidably connected to the guide blocks 17. When the screening cylinder 6 screens the battery materials inside it, the staff turns on the upper third motor 102, so that the threaded rod 103 rotates. The connecting frame 105 moves on the surface of the threaded rod 103, so that the connecting frame 105 extends and contracts reciprocally. The guide blocks 17 slide on the surface of the guide strips 16, and the lower flapping block 106 moves up and down, continuously flapping the surface of the screening cylinder 6 to make the screening cylinder 6 vibrate, preventing the battery materials from clogging the mesh holes of the screening cylinder 6.

[0025] Working principle: When the staff needs to screen battery materials, the staff first pour the battery materials to be screened above the screening plate 43 and turn on the first motor 44 at the rear, so that the screening plate 43 vibrates, and the battery materials on the surface of the screening plate 43 are screened and fall into the feeding hopper 3 below. The battery materials enter the inside of the screening cylinder 6 through the feeding pipe 5 below the feeding hopper 3. At this time, the staff turn on the second motor 81, so that the screening cylinder 6 starts to rotate and conveys the battery materials inside the screening cylinder 6 to the right. The battery materials are screened again by the screening cylinder 6. When the screening cylinder 6 rotates, the staff turn on the third motor 102 above, and the beating block 106 above the screening cylinder 6 will move up and down reciprocally, so that the beating block 106 collides with the surface of the screening cylinder 6, so that the whole screening cylinder 6 vibrates, so as to prevent the battery materials from blocking the mesh holes on the surface of the screening cylinder 6. The screened battery materials will fall to the left side inside the collection box 11, while the unqualified battery materials will fall to the right side inside the collection box 11 and are separated by the partition plate 12, so that the staff can process the unqualified battery materials again later.
