[0031] Please refer to Figure 4 and Figure 5As shown in the figure, the driving assembly includes a driving motor 12, a rotating shaft 121, and a gear set 122. A rotating shaft 121 is rotatably connected between the left and right sides of the middle movable frame 7. A gear set 122 is connected between the right side of the rotating shaft 121 and the screw 11. The gear set 122 is composed of a large gear and a small gear. The large gear is fixedly sleeved on the screw 11, and the small gear is fixedly sleeved on the rotating shaft 121. The small gear meshes with the large gear. A driving motor 12 is installed at the lower part of the left side surface of the middle movable frame 7. The end of the output shaft of the driving motor 12 is fixedly connected to the left end of the rotating shaft 121.

[0032] Please refer to Figures 6-8 As shown in the figure, it further includes a twisting assembly installed on the U-shaped frame 3. The twisting assembly includes a sliding frame 14, a double-acting cylinder 141, a double-shaft moving machine 142, a U-shaped plate 143, an electric rotating rod 144, a rotating block 145, a screw head 1451, and a switching assembly. The sliding frame 14 is slidably connected to the left and right sides of the U-shaped frame 3 symmetrically. The upper parts of the sliding frames 14 on the left and right sides are both installed with double-shaft moving machines 142. U-shaped plates 143 are fixedly connected to the moving parts of the double-shaft moving machines 142 on the left and right sides. An electric rotating rod 144 is installed on the U-shaped plate 143. Rotating blocks 145 are rotatably connected to the ends of the electric rotating rods 144 on the left and right sides close to each other. Three screw heads 1451 are fixedly connected to the rotating block 145 at equal intervals. The models of the three screw heads 1451 are different. A double-acting cylinder 141 is fixedly connected to the rear side of the top of the U-shaped frame 3. The end parts of the telescopic rods on the left and right sides of the double-acting cylinder 141 are respectively fixedly connected to the sliding frames 14 on the left and right sides. A switching assembly is arranged between the rotating block 145 and the electric rotating rod 144. When the switching assembly operates, the switching assembly can drive the rotating block 145 to rotate to switch the screw heads 1451; the switching assembly includes a disc 146, a connecting rod 147, a turntable 148, and a stepping motor 149. A disc 146 is fixedly sleeved on the front side of the shaft part of the rotating block 145. A stepping motor 149 is fixedly connected to the inner side of the electric rotating rod 144. The end of the output shaft of the stepping motor 149 is fixedly connected to a turntable 148. A connecting rod 147 is rotatably connected between the front side surface of the turntable 148 and the front side surface of the disc 146.

[0033] First, the operator places the lithium battery pack on the closing plate II 43, and then starts the driving motor 12 to drive the rotating shaft 121 to rotate. The rotation of the rotating shaft 121 drives the screw 11 to rotate through the gear set 122. The rotation of the screw 11 drives the left and right internal threaded tubes 10 to move outward synchronously. The outward movement of the internal threaded tubes 10 drives the left and right movable frames 7 to move outward synchronously. The outward movement of the left and right movable frames 7 drives the left and right electric limit frames 8 and the support frame 9 to move outward synchronously. When the left and right electric limit frames 8 and the support frame 9 move outward to a position suitable for limiting the plastic shell of the lithium battery pack, the driving motor 12 is turned off, and the lithium battery pack is pushed backward, so that the plastic shell of the lithium battery pack is embedded in the movable frame 7 and the support frame 9, and then the electric limit frame 8 is started to move. The electric limit frame 8 presses and limits the top of the plastic shell of the lithium battery pack, and then the stepper motor 149 is started to drive the turntable 148 to rotate. The turntable 148 rotates and drives the disc 146 to rotate through the connecting rod 147. The rotation of the disc 146 drives the rotating block 145 to rotate. The rotation of the rotating block 145 drives the three screw heads 1451 to rotate. When the screw head 1451 matched with the screw on the lithium battery pack rotates to be parallel to the electric rotating rod 144, the stepper motor 149 is turned off, the turntable 148 stops driving the disc 146 to rotate through the connecting rod 147, and the disc 146 stops driving the screw head 1451 to rotate through the rotating block 145. In this way, screws of different types can be loosened, and then the dual-axis movement is started. The machine 142 drives the electric rotating rods 144 on the left and right sides to move up and down and forward and backward through the U-shaped plate 143. The electric rotating rods 144 drive the screw heads 1451 on the left and right sides to move through the rotating block 145. When the screw heads 1451 move to correspond to the screws of the lithium battery pack, the double-axis moving machine 142 is turned off, and the screw heads 1451 stop moving. Then, the two-way cylinder 141 is started to drive the sliding frames 14 on the left and right sides to move in a direction close to each other. The sliding frame 14 drives the U-shaped plates 143 on the left and right sides to move in a direction close to each other through the double-axis moving machine 142. The U-shaped plates 143 drive the electric rotating rods 144 on the left and right sides to move in a direction close to each other. The electric rotating rods 144 drive the screw heads 1451 on the left and right sides to move in a direction close to each other through the rotating blocks 145 on the left and right sides. The screw head 1451 moves in the direction of being screwed, and when the screw head 1451 is engaged with the screw, the two-way cylinder 141 is closed, and the screw heads 1451 on the left and right sides stop moving in the direction of approaching each other, and the electric rotating rod 144 can be started to drive the screw head 1451 to rotate through the rotating block 145. The screw head 1451 rotates to unscrew the screw on the lithium battery pack, and the screw moves outward during the unscrewing process. At this time, the two-way cylinder 141 is started to make the screw head 1451 move outward synchronously, and the screw can be completely unscrewed. The unscrewed screw falls downward and loses contact with the screw head 1451, and then the two-axis moving machine 142 is started again to make the screw head 1451 correspond to the next screw. The screw can be unscrewed according to the above operation. This process is repeated to unscrew all the screws on the lithium battery pack.After all the screws are removed, start the double-acting cylinder 141 to drive the sliding frames 14 on the left and right sides to move and reset in the direction away from each other, so that the screw heads 1451 on the left and right sides move and reset in the direction away from each other. Then start the electric opening and closing plate 4 to move forward to the maximum stroke, and the electric opening and closing plate 4 stops to close the box body 2. Start the driving motor 12 to drive the rotating shaft 121 to rotate, so that the movable frames 7 on the left and right sides drive the electric limit frames 8 and the support frames 9 on the left and right sides to move outwards. The electric limit frames 8 and the support frames 9 on the left and right sides move outwards to pull the plastic shells on both sides of the lithium battery pack outwards, and the main body of the lithium battery pack is separated from the plastic shells on both sides to complete disassembly. Due to the function of the electric limit frame 8, it can prevent the plastic shell of the lithium battery pack from becoming loose and difficult to separate from the main body of the lithium battery pack. Turn off the driving motor 12, and the electric limit frames 8 and the support frames 9 on the left and right sides stop moving. Then start the electric push plate 13, and the electric push plate 13 moves downwards to contact the main body of the lithium battery pack. The electric push plate 13 pushes the main body of the lithium battery pack downwards to drop into the box body 2, and the main body of the lithium battery pack contacts the electric crushing roller 201. After all the main bodies of the lithium battery pack are pushed down, start the electric push plate 13 to move upwards to reset, and at the same time start the electric limit frame 8 to move upwards to disengage from the plastic shell of the lithium battery pack. The plastic shell of the lithium battery pack stops being limited, and the plastic shell of the lithium battery pack also drops down into the box body 2 to be contacted by the electric crushing roller 201. Then start the electric opening and closing plate 4 to move backwards to reset and continue to close the box body 2. Start the electric crushing roller 201 to rotate to start crushing the main body of the lithium battery pack and the plastic shell of the lithium battery pack. The electric opening and closing plate 4 can prevent the fragments from shooting out of the box body 2 and affecting the environment. The fragments generated by crushing are discharged from the discharge port of the box body 2 for collection. After all the fragments are discharged, the above operations can be performed to disassemble and crush the next lithium battery pack. After all the lithium battery packs are disassembled and crushed, turn off the electric crushing roller 201, start the driving motor 12 to drive the rotating shaft 121 to rotate in the reverse direction. The rotating shaft 121 drives the screw rod 11 to rotate in the reverse direction through the gear set 122. The screw rod 11 drives the movable frames 7 on the left and right sides to move inwards to reset through the internal thread tube 10. The movable frames 7 drive the electric limit frames 8 and the support frames 9 on the left and right sides to move and reset, and then the fragments can be recycled subsequently. In this way, by adjusting the positions of the electric limit frame 8 and the support frame 9, it is possible to adapt to the disassembly and crushing of lithium battery packs with different widths of plastic shells, meet the needs of diversified lithium battery recycling, and thus improve the adaptability.

[0034] Please refer to Figures 9-11As shown, the lithium battery recycling crushing and disassembling equipment further includes a material distribution component installed on the box body 2. The material distribution component includes a swing plate 15, a return spring 1501, a wire winding wheel 151, a wire 152, a U-shaped rod 153, a double-rod cylinder 154, a wire guide frame 155 and a transmission component. A U-shaped rod 153 is vertically and slidably inserted through the rear side of the return frame 3. The top of the U-shaped rod 153 contacts the rear side of the bottom of the closing plate I 42. When the U-shaped rod 153 moves upward, the U-shaped rod 153 can push the closing plate I 42 to swing. A double-rod cylinder 154 is fixedly connected to the middle of the outer rear side of the box body 2. The end of the telescopic rod of the double-rod cylinder 154 is fixedly connected to the bottom of the U-shaped rod 153. A wire guide frame 155 is fixedly inserted through the lower part of the outer rear side of the box body 2. A swing plate 15 is rotatably connected between the lower parts on the left and right sides of the box body 2. The swing plate 15 can close the discharge port of the box body 2. A return spring 1501 is symmetrically connected between the upper part of the swing plate 15 and the inner side of the box body 2 on the left and right. Wire winding wheels 151 are symmetrically and fixedly sleeved on the left and right sides of the shaft part of the swing plate 15. Wires 152 are wound around the wire winding wheels 151. The tails of the wires 152 on the left and right sides pass through the wire guide frame 155 and are fixedly connected to the bottom of the U-shaped rod 153. A transmission component is arranged between the closing plate I 42 and the closing plate II 43. When the transmission component operates, the transmission component can drive the closing plate II 43 to swing. The transmission component includes a connecting rod 156 and a swing rod 157. Swing rods 157 are symmetrically and fixedly sleeved on the left and right sides of the shaft parts of the closing plate I 42 and the closing plate II 43. A connecting rod 156 is rotatably connected between the tails of the corresponding swing rods 157 on the front and rear sides.

[0035] When the electric opening and closing plate 4 moves forward to the maximum stroke and stops to close the box body 2, the main body of the lithium battery pack is pushed into the box body 2 by the electric push plate 13 and contacts the electric crushing roller 201. Then, start the electric opening and closing plate 4 to move backward and reset to close the box body 2. Start the electric crushing roller 201 to rotate to crush the main body of the lithium battery pack. The fragments generated by the crushing of the main body of the lithium battery pack are discharged from the discharge port on the front side of the box body 2 for collection. When all the main body of the lithium battery pack is crushed and discharged, start the double-rod cylinder 154. The telescopic rod of the double-rod cylinder 154 extends to drive the U-shaped rod 153 to move upward. The upward movement of the U-shaped rod 153 pushes the rear side of the closing plate I 42 to swing upward, and the tension spring 44 is stretched. The upward swing of the rear side of the closing plate I 42 drives the support frame 9 to swing, and the connecting spring 91 is compressed. At the same time, the upward swing of the rear side of the closing plate I 42 also causes the front side to swing downward. The closing plate I 42 swings and disengages from the closing plate II 43. At the same time, the swing of the closing plate I 42 drives the rear swing rod 157 to swing downward. The downward swing of the rear swing rod 157 drives the front swing rod 157 to swing upward through the connecting rod 156. The upward swing of the front swing rod 157 drives the closing plate II 43 to swing downward to an inclined state. The closing plate II 43 and the closing plate II 43 stop closing the box body 2 at this time. At the same time, the upward movement of the U-shaped rod 153 drives the pull wire 152 to move upward. The upward movement of the pull wire 152 drives the left and right winding wheels 151 to reverse through the wire guide frame 155. The reverse rotation of the winding wheel 151 drives the swing plate 15 to swing forward, and the return spring 1501 is stretched. The forward swing of the swing plate 15 closes the discharge port on the front side of the box body 2. The swing plate 15 stops closing the discharge port behind the box body 2. Then, start the electric limit frame 8 to move upward and disengage from the plastic shell of the lithium battery pack. The plastic shell of the lithium battery pack drops downward into the box body 2 and is crushed by the electric crushing roller 201. The fragments generated by the crushing are discharged and collected through the discharge port on the rear side of the box body 2. When all the plastic shells of the lithium battery pack are crushed and discharged, start the double-rod cylinder 154 to drive the U-shaped rod 153 to move downward and reset. The reset of the U-shaped rod 153 stops limiting the closing plate I 42. Due to the action of the tension spring 44, the swing plate of the closing plate I 42 resets and drives the support frame 9 to swing and reset. The reset of the support frame 9 causes the connecting spring 91 to reset. The reset of the closing plate I 42 drives the closing plate II 43 to swing upward and reset through the swing rod 157 and the connecting rod 156. The reset of the U-shaped rod 153 relaxes the pull wire 152. Due to the action of the return spring 1501, the swing plate 15 swings backward and resets to drive the winding wheel 151 to rotate forward and reset. The forward rotation of the winding wheel 151 winds up the pull wire 152. The swing plate 15 resets to close the discharge port on the rear side of the box body 2. In this way, the fragments of the main body of the lithium battery pack and the fragments of the plastic shell can be separated for collection, which is convenient for subsequent recycling and treatment of the fragments.

[0036] Please refer to Figure 1As shown in the figure, the lithium battery recycling, crushing and disassembling equipment further includes a corrugated cover 16. Corrugated covers 16 are fixedly connected to both discharge ports of the box body 2, and the corrugated covers 16 can block the dust generated during the discharging process.

[0037] When the debris is discharged from the discharge port of the box body 2, the debris is discharged into the corrugated cover 16, and the debris in the corrugated cover 16 is discharged for collection and treatment. The corrugated cover 16 can block the dust generated during the discharging process. In this way, the dust generated during the discharging process can be prevented from affecting the surrounding environment, thus ensuring a good working environment.
