The arc-shaped telescopic cylinder 11 is used to drive the L-shaped rod 12 to rotate, so that the sealing cover 13 opens and closes the end of the discharge pipe 14. It can be understood that the arc-shaped telescopic cylinder 11 can be arranged as an arc structure as needed, and the center of the arc-shaped telescopic cylinder 11 is located on the axis of the hinge shaft between the L-shaped rod 12 and the disassembly box 4, which is conducive to the stable and reliable transmission of the arc-shaped telescopic cylinder 11.

[0046] like Figure 1 , 2 , 7 and 8, as a preferred embodiment of the present invention, the waste lithium battery disassembly equipment also includes a secondary shredding component, the secondary shredding component includes a material guide seat 15, a rotating shaft 18, a cutting knife 19 and a motor three 40, the inner bottom of the disassembly box 4 is fixed with a conical material guide seat 15, the inner bottom middle position of the material guide seat 15 is fixed with a motor three 40, the output end of the motor three 40 is fixed with a rotating shaft 18, and the upper end of the rotating shaft 18 is circumferentially fixed with a plurality of cutting knives 19, the outer end of the cutting knife 19 is inclined upward, and the cross-section of the cutting knife 19 is a cross shape, and the cutting knife 19 is driven to rotate by the motor three 40, so that the lithium batteries falling from the discharge channel 22 can be further cut, which is beneficial to the subsequent sorting and crushing; the material guide seat 15 can be used for reliable material guiding, which is beneficial to the controlled discharge through the discharge pipe 14.

[0047] In one embodiment, the upper end of the material guide seat 15 is slidably and rotatably mounted with a linkage seat 17 on the rotating shaft 18, and a paddle 16 parallel to the surface of the material guide seat 15 is fixed on the outer side of the linkage seat 17.
