[0034] See attached document Figure 1 -Appendix Figure 6 As a first embodiment of the present invention, the present invention provides an automatic stripping and metal foil collection device for lithium battery electrodes, including a scrap box 1, the scrap box 1 is a square structure, the top of the scrap box 1 is provided with a feeding pipe 2, the inside of the scrap box 1 is provided with a scraping mechanism, the bottom of the scrap box 1 is fixedly connected with multiple support legs 3, the bottom of the scrap box 1 is provided with two separation cylinders 4, both of the separation cylinders 4 are cylindrical structures, the inside of the two separation cylinders 4 is provided with a collection mechanism, the top of the two separation cylinders 4 is provided with a cover plate 5, the outside of the separation cylinders 4 is provided with multiple ventilation slots 6, and the inside of the two separation cylinders 4 is provided with partition strips 49;

[0035] It needs to be explained that the design of multiple partition bars 49 inside the separator 4 allows the crushed material to tumble over a wider area and with a greater amplitude inside the separator 4, thereby preventing the material from accumulating inside the separator and resulting in a better subsequent stripping effect.

[0036] The crushing mechanism includes a servo motor 7, which is located on the top of the crushing box 1. The output end of the servo motor 7 is fixedly connected to a drive shaft 8, and the bottom end of the drive shaft 8 extends into the interior of the crushing box 1. A crushing blade 9 is embedded inside the crushing box 1, and the crushing blade 9 is fixedly sleeved on the outside of the drive shaft 8.

[0037] The crushing mechanism also includes two return boxes 10, which are fixedly connected to both sides of the crushing box 1. Each of the two return boxes 10 is equipped with a spiral conveyor rod 11, and the two spiral conveyor rods 11 are movably connected to the return box 10 through rolling bearings.

[0038] The top of the shredder 1 is provided with a fixed frame 12, which is located at the bottom of the servo motor 7. The fixed frame 12 is provided with a first sprocket 13 inside the fixed frame 12. The first sprocket 13 is fixedly sleeved on the outside of the transmission shaft 8. A second sprocket 14 is fixedly sleeved on the outside of one of the spiral transmission rods 11. A first chain 15 is sleeved on the outside of the first sprocket 13 and the second sprocket 14. The first sprocket 13 and the second sprocket 14 are driven and connected through the first chain 15.

[0039] The crushing mechanism also includes two transmission gears 16, which are located on the front and rear sides of the crushing box 1. A toothed ring 17 is provided on the outside of the crushing box 1, which meshes with the two transmission gears 16. The two transmission gears 16 are respectively fixedly sleeved on the outside of the two spiral conveying rods 11. Limiting frames 18 are provided on both sides of the crushing box 1. A limiting ring 19 is provided inside the limiting frame 18. The limiting ring 19 is embedded on the outside of the toothed ring 17 and slides with the toothed ring 17.

[0040] The crushing box 1 is equipped with a filter plate 20. The filter plate 20 is movably connected to the drive shaft 8 through a rolling bearing. The crushing box 1 has a discharge port 21 and a return port 22 on both the front and rear sides. The top of the filter plate 20 is equipped with multiple baffles 23, which are respectively located on both sides of the two discharge ports 21.

[0041] In this embodiment, the user places the electrode sheet into the crushing bin 1 and starts the servo motor 7. The servo motor 7 drives the drive shaft 8 and multiple crushing blades 9 to rotate. The crushing blades 9 crush the electrode sheet. The crushed material falls through the filter plate 20 into multiple collection tanks 32 at the bottom. At the same time, the electrode sheet that is not completely crushed enters the two return bins 10 through the discharge port 21. When the drive shaft 8 rotates, it drives the first sprocket 13 and the second sprocket 14 to rotate. The rotation of the second sprocket 14 drives one of the spiral conveyor rods 11 to rotate. The rotation of one of the spiral conveyor rods 11 drives the drive gear 16 and the gear ring to rotate, thereby causing the other spiral conveyor rod 11 to rotate. The rotation of the two spiral conveyor rods 11 transports the incompletely crushed material to the top and then enters the crushing bin 1 again through the return port 22, so that the crushing blades 9 can crush the incompletely crushed battery electrode sheet again, making the battery electrode sheet crushed more thoroughly.

[0042] See attached document Figure 10As a second embodiment of the present invention, the present invention provides an automatic lithium battery electrode stripping and metal foil collection device, wherein two horizontal plates 43 are provided between the support legs 3, and heating boxes 44 are provided on the outer side of the two horizontal plates 43.

The heating end of the heater 48 is located on the top of the blower fan blade 47, and the heat dissipation end of the heater 48 is located on the outer side of the heating box 44.

[0043] In this embodiment, the user starts the two blower motors 46 and the heater 48. The blower motors 46 cause the two blower fan blades 47 to rotate. The rotating blower fan blades 47 blow air into the two separation cylinders 4. At the same time, the heater 48 heats the blown air, so that the high-temperature air enters the separation cylinder 4 and peels off the electrode sheet at high temperature, so that the electrode sheet is separated from the metal foil.

[0044] See attached document Figure 7 -Appendix Figure 9As a third embodiment of the present invention, the present invention provides an automatic lithium battery electrode stripping and metal foil collection device. The collection mechanism includes a recycling box 24, which is located at the bottom of the scrap bin 1. A vacuum cleaner 25 is provided at the bottom of the recycling box 24. A filter screen 26 is provided inside the recycling box 24. A connecting pipe 50 is provided at the top of the recycling box 24. A suction pipe 27 is provided at the top of the connecting pipe 50. The two ends of the suction pipe 27 extend into the interior of two separation cylinders 4, respectively. A connecting ring 28 is provided between the separation cylinders 4 and the suction pipe 27. The suction pipe 27 and the connecting ring 28 are movably connected by a rolling bearing. Positioning frames 29 are fixedly connected to both sides of the scrap bin 1. The two positioning frames 29 are respectively sleeved on the outside of the two connecting rings 28 and movably connected to the connecting rings 28 by rolling bearings. A positioning plate 30 is provided at the bottom of each of the two positioning frames 29. A flow pipe 31 is provided at the inner end of each of the two separation cylinders 4. The positioning plate 30 and the flow pipe 31 are movably connected by a rolling bearing. Multiple openings are provided at the bottom of the scrap bin 1. Each collection trough 32 has two flow pipes 31 connected to multiple collection troughs 32. The front side of the crushing bin 1 is provided with two top plates 33, and the bottom of each top plate 33 is provided with a hydraulic rod 34. The front side of each crushing bin 1 is provided with a lifting plate 35, which is sleeved on the outside of the return bin 10. The lifting plate 35 is fixedly connected to the bottom of the two hydraulic rods 34. The bottom of the lifting plate 35 is provided with two toothed plates 36, and the front side of each toothed plate 36 is provided with a connecting gear 37. The connecting gear 37 meshes with the toothed plate 36. The front side of each of the two positioning frames 29 is fixedly connected with a fixing plate 38. A movable shaft 39 is provided between the two fixing plates 38. The movable shaft 39 is embedded in the two connecting gears 37. The outside of the movable shaft 39 is fixedly sleeved with two third sprockets 40. The outside of each of the two connecting rings 28 is fixedly sleeved with a fourth sprocket 41. The outside of the third sprockets 40 and the fourth sprockets 41 is sleeved with a second chain 42. The third sprockets 40 and the fourth sprockets 41 are driven and connected by the second chain 42.

[0045] In this embodiment, when the completely crushed battery electrode fragments enter the two separating cylinders 4 through the collection tank 32 and the flow pipe 31, the user activates the hydraulic rod 34, causing it to reciprocate. This reciprocating motion of the hydraulic rod 34 drives the lifting plate 35 to move up and down, which in turn drives the two toothed plates 36 to move up and down. This movement of the two toothed plates 36 drives the two connecting gears 37 to rotate, which in turn drives the movable shaft 39 to rotate. This rotation of the movable shaft 39 drives the third sprocket 40 and the fourth sprocket 41 to rotate, which in turn drives the two connecting rings 28 and the separating cylinders 4 to rotate. The rotation of the separating cylinders 4 causes the electrode fragments inside to be lifted up. When the heating device heats the electrode sheets inside, the electrode sheets separate from the metal foil. The lighter electrode sheets are sucked into the collection box by the vacuum cleaner 25, while the metal foil remains inside the separating cylinders 4 for easy collection by the staff.

[0046] The usage process of this invention is as follows: The user places the electrode sheet into the crushing bin 1 and starts the servo motor 7. The servo motor 7 drives the transmission shaft 8 and multiple crushing blades 9 to rotate. The crushing blades 9 crush the electrode sheet. The crushed material falls through the filter plate 20 into multiple collection tanks 32 at the bottom. At the same time, the completely crushed electrode sheet enters the two return bins 10 through the discharge port 21. When the transmission shaft 8 rotates, it drives the first sprocket 13 and the second sprocket 14 to rotate. The rotation of the second sprocket 14 drives one of the... The rotating spiral conveyor rods 11 drive the transmission gear 16 and gear ring to rotate, thereby causing the other spiral conveyor rod 11 to rotate. The rotation of the two spiral conveyor rods 11 transports the incompletely crushed material to the top, and then it re-enters the crushing box 1 through the return port 22, allowing the crushing blades 9 to further crush the incompletely crushed battery electrodes, making the battery electrodes more thoroughly crushed. The user starts the two blower motors 46 and the heater 48 to work. The blower motors 46 cause the two blower fan blades 47 to rotate, and the blower... The fan blades 47 rotate to blow air into the two separation cylinders 4, while the heater 48 heats the air, allowing the high-temperature air to enter the separation cylinders 4 and perform high-temperature peeling of the electrode plates, separating them from the metal foil. When the completely crushed battery electrode fragments enter the two separation cylinders 4 through the collection tank 32 and the flow pipe 31, the user activates the hydraulic rod 34, causing it to reciprocate. This reciprocating motion of the hydraulic rod 34 moves the lifting plate 35 up and down, which in turn moves the two toothed plates 36 up and down. The toothed plate 36 moves up and down, causing the two connecting gears 37 to rotate. The rotation of the two connecting gears 37 causes the movable shaft 39 to rotate. The rotation of the movable shaft 39 causes the third sprocket 40 and the fourth sprocket 41 to rotate. The rotation of the fourth sprocket 41 causes the two connecting rings 28 and the separation cylinder 4 to rotate. The rotation of the separation cylinder 4 causes the electrode fragments inside to be thrown up. When the heating device heats the electrode pieces inside, the electrode pieces separate from the metal foil. The lighter electrode pieces are sucked into the collection box by the vacuum cleaner 25, while the metal foil remains inside the separation cylinder 4 for easy collection by the staff.
