[0068] Embodiment 2:

[0070] The material compression box 13 is arranged at the bottom end of the waste collection area 3 and is used for collecting the falling edge material;

[0071] The blocking plate 14 is slidingly connected to the top end of the material compression box 13;

[0077] ​Example 3:

[0078] like Figures 1-3 As shown, based on the above embodiment 2, a waste collection vehicle 18 is provided on the outside of the outer shell 1, and a lockable door is provided on the side of the pressing box 13 away from the second electric telescopic rod 17. The feeding end of the waste collection vehicle 18 is connected to the door.

[0079] The working principle and beneficial effects of the above technical solution are as follows:

[0080] A waste collection vehicle 18 is set up on one side of the equipment. After the edge material is compacted, the box door on one side of the pressing box 13 is opened, and the second electric telescopic rod 17 is controlled to continue to extend, so that the waste material passes through the box door and moves into the waste collection vehicle 18. No manual handling is required, and the waste material is discharged quickly.

[0081] Example 4:

[0082] like Figures 3-5 As shown, based on the above embodiment 1, a scattering unit is provided at the bottom of the waste collection area 3. The scattering unit includes:

[0083] Support plate 21 is inclinedly connected to the inner wall of the outer shell 1 and located below the guide plate 12;

[0084] Back plate 22 is connected between guide plate 12 and support plate 21. Back plate 22, support plate, guide plate 12 and outer shell 1 form a receiving area for guide roller 8.

[0085] The receiving plate 23 is inclinedly disposed below the guide roller 8;

[0086] Spraying plate 24 is connected to the bottom end of receiving plate 23 and is arranged close to the feed inlet of pressing zone 2. Spraying plate 24 is shaped like a bucket.

[0087] A bent rod 25 is connected to the side edge of the spray plate 24 and extends upward. The top of the bent rod 25 is hinged to the outer shell 1 through a pivot 28, and the pivot 28 extends out of the outer shell 1.

[0088] The paddle 26 extends from the end of the guide roller 8 out of the housing 1. Multiple paddles 26 are connected to the extended end of the guide roller 8 and are evenly arranged around the circumference of the guide roller 8.

[0089] The pressure rod 27 has its bottom end connected to the rotating shaft 28, and its top end extends towards the guide roller 8. A spring is connected between the side end of the pressure rod 27 and the housing 1.

[0090] The working principle and beneficial effects of the above technical solution are as follows:

[0091] The lithium battery pole piece waste slides along the guide plate 12, and the dust and the edge material are separated during the sliding process. Since the sliding speed is fast, incomplete separation is prone to occur. Therefore, a throwing unit is arranged at the bottom of the waste collecting area 3. When the throwing unit is used, the motor is started to drive the guide roller 8 to rotate clockwise. The waste moves downward under the action of the guide roller 8 and falls on the receiving plate 23, and then slides along the receiving plate 23 to the throwing plate 24. Since the throwing plate 24 is arranged in the form of a hopper, the waste is concentrated in the hopper instead of directly falling into the pressing area 2. When the guide roller 8 rotates, the paddle 26 at the end thereof rotates with it. When the paddle 26 rotates to contact the pressing rod 27, the pressing rod 27 rotates around the rotating shaft 28 and simultaneously stores energy in the spring. The rotating shaft 28 drives the bent rod 25 to rotate, thereby driving the throwing plate 24 to rotate counterclockwise. The throwing plate 24 throws the waste in the interior thereof. After the waste is thrown out, the edge material falls into the pressing area 2 under the action of gravity because the weight of the edge material is greater than that of the dust. The dust enters the dust removal area 4 under the action of the suction force of the fan. Part of the edge material collides with the blocking plate 19 and falls under the blocking of the blocking plate 19. After completing the throwing, the pressing rod 27 is reset under the action of the spring, thereby driving the throwing plate 24 to reset. With the rotation of the guide roller 8, the above-mentioned actions are repeatedly performed to realize the cyclic throwing. The support plate 21 is arranged in an inclined manner, so that part of the edge material falling on the support plate 21 can smoothly slide down and avoid being blocked.

[0092] Through the above structural design, the waste does not directly fall into the pressing area 2 when it slides, but falls into the hopper of the throwing plate 24 and performs the cyclic upward throwing action, thereby prolonging the time of the waste in the waste collecting area 3. The edge material and the dust are better separated under the action of the throwing and suction forces, the treatment effect of the waste is improved, and the influence of the mixed too much dust in the edge material on the subsequent recycling is avoided.

[0093] Embodiment 5:

[0094] As shown in Figures 3-5 the above embodiment 4, the throwing unit further comprises:

[0095] The arc-shaped plate 29 is rotationally connected to the inner wall of the shell 1 at the top end thereof and is attached to the lower part of the guide roller 8. The bottom end of the arc-shaped plate 29 is connected to the top end of the receiving plate 23. The arc-shaped plate 29 is arranged in the form of a rubber plate.

[0096] The working principle and beneficial effects of the above technical solution are as follows:

[0097] When the dispensing unit is in use, an arc-shaped plate 29 is installed below the guide roller 8. This plate catches the waste material as it falls through the gap between the guide roller 8 and the receiving plate 23. The arc-shaped plate 29 is a flexible plate; as the receiving plate 23 rotates, it separates and unfolds from the guide roller 8. The waste material on the arc-shaped plate 29 can slide onto the receiving plate 23, preventing excessive accumulation of waste material on the support plate 21 and affecting the transmission. When the receiving plate 23 resets, the arc-shaped plate 29 also resets.

[0098] Example 6:

[0099] like Figures 4-7 As shown, based on the above embodiment 4, the spraying unit further includes:

[0100] Link 31 is connected to the bottom of the bent rod 25, and the bottom end of the link 31 extends toward the bottom end of the spray plate 24. A gear is rotatably connected to the bottom end of the link 31.

[0101] Spraying roller 32 is connected to gear shaft. Multiple blades 33 are evenly connected on the spraying roller 32, and the bottom end of the blades 33 contacts the inner wall of the spraying plate 24.

[0102] An arc-shaped rack 34 is connected to the inner wall of the housing 1. The gear meshes with the arc-shaped rack 34. A sealing cover 35 is connected to the outside of the arc-shaped rack 34. An arc-shaped groove 36 for the gear shaft to move is provided on the sealing cover 35. A sealing strip 37 is provided on the groove opening of the arc-shaped groove 36.

[0103] The working principle and beneficial effects of the above technical solution are as follows:

[0104] When the spraying unit is in use, the spraying roller 32 is installed in the hopper of the spraying plate 24 via the connecting rod 31. When the spraying plate 24 rotates, the gear on the bent rod 25 meshes with the arc-shaped rack 34, causing the spraying roller 32 to rotate. The rotation of the spraying roller 32 carries the waste material out of the hopper of the spraying plate 24, allowing the waste material to be thrown out more smoothly and improving the separation effect of edge material and dust. A sealing cover 35 is set on the arc-shaped rack 34, and the gear shaft can move along the arc-shaped groove 36. A sealing strip is set on the arc-shaped groove 36, allowing the gear shaft to pass through the arc-shaped groove 36. At the same time, the area of ​​the arc-shaped groove 36 is sealed to prevent waste material from entering the arc-shaped rack 34 and affecting the gear transmission.

[0112] The working principle and beneficial effects of the above technical scheme are:

[0113] The elastic element 40 is arranged below the material receiving plate 23, the locking bolt 47 is sequentially inserted into the lugs 44 of the upper and lower clamping plates 41 from below during installation, the end of the locking bolt 47 is clamped in the counterbore hole 46, the bolt rod of the locking bolt 47 is clamped in the arc through slot 45, the bolt rod is prevented from rotating, then the nut is arranged on the material receiving plate 23, and the material receiving plate 23 and the locking bolt 47 are tightened. When the material receiving plate 23 rotates to be close to the support plate 21, the elastic element 40 contacts the support plate 21. After the clamping plate 41 collides onto the support plate 21, pressure is applied to the flexible pipe 42, so that the flexible pipe 42 is deformed, and the support plate 21 is buffered. When the flexible pipe 42 is deformed, the adjacent flexible pipes 42 collide, the rigid bumps 43 on the adjacent flexible pipes 42 collide, vibration and movement trend are generated, the flexible pipe 42 is shaken, the support plate 21 is shaken and the shaking amplitude is more irregular, so that the residual waste on the support plate 21 is better shaken off, dust accumulation on the support plate 21 is avoided, the waste on the support plate 21 is prevented from falling back into the arc-shaped plate 29, and the reliability of the equipment is improved.
