A partition plate 13 is fixedly connected to the inner side of the crushing box 2. A spring slide bar 14 is installed on the top of the partition plate 13. A limit rod 15 is fixedly connected to the bottom of the partition plate 13. The outer side of the limit rod 15 slides A sliding plate 16 is connected, and two pull ropes 17 are fixedly connected to the outer side of the sliding plate 16, and the other ends of the two pull ropes 17 are fixedly connected to the bottom end of the spring slide bar 14, and an auxiliary rod 18 is fixedly connected to the bottom of the partition plate 13, and the outer side of the pull rope 17 is slidably connected to the outer side of the auxiliary rod 18. A plurality of discharge holes 25 are provided around the outer wall of the crushing box 2, and a material receiving trough 26 is fixedly connected to the outer periphery of the crushing box 2.

[0047] Specifically, the crushed debris will fall onto the screen 8, and at this time, the two fans 22 will blow the broken diaphragm out through the discharge port 23 and collect it with the receiving hopper 24. At the same time, driven by the crushing roller 4, the pulley 2 7 and the pulley 3 27 are linked, and the conveyor 20 is a structure composed of two groups of two sprockets and chains, and the paddle 21 is installed between the two chains, and the two rotating rods 19 are fixedly connected to the two groups of sprockets. Driven by the pulley 3 27, the chain will drive the two paddles 21 to move, and the spring slide bar 14 is composed of a spring sleeved on the outside of the rod, one end of the spring is connected to the top of the rod, and the other end is connected to the top of the partition plate 13, and the rod slides through the partition plate 13. The outside of the limit rod 15 has a protrusion, which can limit the sliding plate 16 to make its sliding stable. When the paddle plate 21 is moved, the sliding plate 16 will pull the spring slide bar 14 through the two pull ropes 17. When the paddle plate 21 moves to the head and separates from the sliding plate 16, the spring slide bar 14 will be affected by the elastic force and hit the impact block 12 to make the screen 8 move upward and then fall down by gravity.

In this way, the screen 8 is repeatedly hit to achieve a screening effect, so that the black powder inside the crushed lithium battery falls through the mesh of the screen 8 to the top of the partition plate 13, and then is discharged from the discharge hole 25 and collected by the receiving trough 26. The auxiliary rod 18 can allow the pull rope 17 to form a right angle, so that the spring slide bar 14 is more stable under the downward pulling force, and the screen 8 is tilted to facilitate the remaining copper and aluminum sheet debris to be discharged through the discharge port 61.

In addition, when the transmission rod 1 28 rotates, the pulley 6 53 and the pulley 5 52 will be linked, and the rotating rod 2 50 will drive the cam 51 to rotate, so that the ventilation plate 49 vibrates, so as to prevent part of the aluminum powder from being mixed in the copper powder. , piled on the ventilation plate 49, driven by the motor 240, the push plate 45 will push the blown aluminum powder to the side close to the discharge port 3 56 for discharge, and then be collected by the receiving hopper 3 57. When the push plate 45 moves back, it is inevitable that some aluminum powder will be pushed to the side away from the discharge port 3 56. Therefore, there are no mesh holes at both ends of the ventilation plate 49 close to the discharge port 3 56 and the feed port 60, and the wind will not blow up the aluminum powder.
