One end of the U-shaped square tube 13 is slidably inserted into the square hole opened in the middle of the T-shaped box 17. The U-shaped square tube 13 is externally connected to the gas supply mechanism in the prior art, and gas is injected into the U-shaped square tube 13. A part of the gas is injected into the T-shaped box 17. 7, the air pressure acts on the T-box 17, the T-box 17 translates to drive the scraper 15, the edge of one side of the scraper 15 presses on the battery core 3, the battery core 3 rotates counterclockwise, and the scraper 15 encounters the edge of the battery core 3 and scrapes up the belt. After the battery core 3 continues to rotate, the belt gradually tilts up and extends outward, and the air in the T-box 17 is discharged through the split cylinder 16.

As the battery core 3 belt gradually extends out, a Figure 6 In the state shown, the airflow ejected from the sub-cylinder 16 flows forward rapidly, and the airflow also generates a certain adsorption force on the surroundings, so that the strip of battery core 3 is adsorbed and extended to the left along the airflow until the strip of battery core 3 is transported and attached to the mesh cylinder 8.

[0036] The mesh tube 8 is an annular tube with mesh holes, and an inner gear ring is arranged on the edge of one end of the annular tube. The long wheel 9 is an I-shaped tube, and the middle part of the long wheel 9 is fixed to the main board 1 by setting an axis.

[0038] The shaft group 14 also includes a power shaft 22 and a flat rubber disc 21. The fixed shaft plate 23 supports the power shaft 22. One end of the power shaft 22 is connected to the helical teeth on the fixed gear and the worm 24 through the meshing transmission. The other end of the power shaft 22 is contacted and driven with the push piece 6 through the fixed flat rubber disc 21. The side shaft 20, the power shaft 22 and the worm 24 are respectively movably sleeved in different through holes opened on the fixed shaft plate 23.

[0039] refer to Fig. 9 It is understood that the push piece 6 includes a double-controlled roller 26 in contact with the battery core 3, a recessed frame 25 supporting the double-controlled roller 26, a power tool 32 connected to the double-controlled roller 26, a slide 28 and a telescopic plate 29 vertically fixed on the recessed frame 25, a square plate box 31 slidably inserted by the telescopic plate 29, a hard air tube 30 fixedly connected to the square plate box 31, and a spring 27 sleeved on the slide 28, one end of the hard air tube 30 is fixedly connected to the U-shaped square tube 13, the slide 28 slides through the inner hole of the cylinder fixed on the square plate box 31, and the spring 27 is supported between the cylinder of the square plate box 31 and the ring body fixed on the slide 28, and the shaft body at the end of the double-controlled roller 26 is movably sleeved in the through hole opened at the end of the recessed frame 25.

[0040] The power tool 32 includes a vertical rubber disc 33, a head shaft 34 and a tail shaft 39. The vertical rubber disc 33 is in vertical contact with the flat rubber disc 21. One end of the head shaft 34 is fixedly connected to the vertical rubber disc 33. The other end of the head shaft 34 is connected to the vertical rubber disc 33 through a column gear and a column gear fixed at one end of the tail shaft 39. The other end of the tail shaft 39 is connected to the bevel gear fixed at the end of the double-controlled roller 26 through a fixed bevel gear.

[0041] The power tool 32 also includes a swimming plate 35 supporting a head shaft 34, a follower block 38 supporting a tail shaft 39, a limiting spring piece 36 connected between the follower block 38 and the swimming plate 35, and a horizontal square column 37 fixed on the follower block 38. The horizontal square column 37 slides through a square hole opened on the swimming plate 35. The follower block 38 is fixed on the recessed frame 25. The head shaft 34 is movably sleeved in the inner hole of the cylinder provided on one side of the swimming plate 35, and the tail shaft 39 is movably sleeved in the through hole opened on the follower block 38.

[0042] The interception group 12 includes an interception plate 40, a restraining plate 41 and a pressure spring plate 42. The restraining plate 41 is fixed on the main board 1. The interception plate 40 slides through the plate hole opened on the restraining plate 41, and one end of the interception plate 40 contacts the outer wall of the net tube 8, and the edge of the other end of the interception plate 40 contacts the pressure spring plate 42, and one end of the pressure spring plate 42 is fixed on the restraining plate 41.

[0043] The unwinding and disassembling of the battery core 3 is divided into two stages. In the first stage, the battery core 3 placed in the funnel tube 2 falls between the double-controlled roller 26 and the clamping rod 5, and then air is injected into the U-shaped square tube 13. The airflow is injected into the square plate box 31 through the hard air tube 30. The air pressure in the square plate box 31 acts on the telescopic plate 29, and the telescopic plate 29 extends from the square plate box 31. The telescopic plate 29 drives the recessed frame 25 to translate, and then drives the double-controlled roller 26 to translate. The double-controlled roller 26 pushes the battery core 3, and the other side of the battery core 3 is intercepted and clamped by the two clamping rods 5. In this way, the battery core 3 is triangularly clamped and positioned. At the same time, the translation of the recessed frame 25 will drive the power tool 32. Fig. 9 and Fig.10 It is understood that when the power tool 32 is translated to the right as a whole, the flat rubber disc 21 first intercepts and hooks the vertical rubber disc 33, so that the rotation of the flat rubber disc 21 will drive the vertical rubber disc 33 to rotate, and then the recessed frame 25 continues to translate to the right, driving the horizontal column 37 and the follower block 38 to move synchronously. During the process, the limit spring piece 36 is pulled apart, and the head shaft 34 and the tail shaft 39 are always meshed and connected. The transmission inside the power tool 32 always exists, that is, the worm 24 is externally connected to the motor drive mechanism in the prior art, and the rotation of the worm 24 drives the power shaft 22, and then the flat rubber disc 21 rotates, and the double-sided rubber disc 21 is driven by the transmission path in the power tool 32. The control roller 26 rotates, and the rotation of the double-control rollers 26 will cause the battery core 3 to rotate. While the double-control rollers 26 push the battery core 3 to translate, they will also drive the battery core 3 to rotate. The battery core 3 starts to rotate because gas is injected into the U-shaped square tube 13. After the gas injection stops, the battery core 3 stops rotating because the power tool 32 of the driving source moves in the opposite direction as a whole and resets. Finally, the vertical rubber disk 33 and the rotating flat rubber disk 21 are separated, causing the subsequent double-control rollers 26 to stop rotating. Combined with the scraping principle process of the scraper 7 on the battery core 3, it can be seen that the initial reverse winding and disassembly control node of the battery core 3 is to inject gas into the U-shaped square tube 13.

[0044] After the belt on the battery core 3 is conveyed and attached to the mesh drum 8, the air injection in the U-shaped square tube 13 is stopped, so that the double-controlled roller 26 and the scraper 15 are separated from the battery core 3, and the worm 24 rotates to drive the side shaft 20, and then the side gear 19 rotates to drive the mesh drum 8. The rotation of the mesh drum 8 will drive the adsorbed battery core 3 belt, so that the battery core 3 continues to be unwound and disassembled because it is pulled by the mesh drum 8, and the cylindrical diameter of the battery core 3 gradually decreases. Finally, the battery core 3 passes through the two clamping rods 5. The battery core 3 with a smaller diameter will be intercepted by the guide plate 11 again, and the mesh drum 8 continues to rotate, so that the battery core 3 continues to be unwound and disassembled until it is completely disassembled.

[0045] The reason why the battery core 3 strip is attached to the mesh tube 8 is because of the suction force at the air hole of the air shell 10 ring box. The L-shaped air pipe of the air shell 10 is externally connected to the air extraction mechanism in the prior art, so that the outside air is sucked into the air shell 10 ring box through the air hole on the air shell 10 ring box, and then discharged through the L-shaped air pipe of the air shell 10. The suction force at the air hole acts on the battery core 3 strip, so that the strip is transported along with the rotation of the mesh tube 8, and the battery core 3 is pulled and completely disassembled. Fig.12 The air holes of the air shell 10 ring box have a distribution range. After the battery core 3 belt body is transported away from the air holes, the suction force disappears, so that the belt body adsorbed on the mesh tube 8 will fall off. After the belt body falls completely, the belt body has been fully unfolded, and the anode and cathode sheets in the belt body are completely exposed, and can be directly and conveniently pulled off from the belt body.

[0046] A rewinding process for waste battery treatment comprises the following steps:

[0047] Step 1: Collect the battery cells 3 that meet the rewinding disassembly specifications, put the battery cells 3 into the funnel tube 2, and let the battery cells 3 fall to the disassembly station.

[0048] Step 2: The pusher 6 pushes the battery core 3 to move horizontally until the battery core 3 is intercepted and positioned by two opposite clamping rods 5. The pusher 6 drives the battery core 3 to rotate. At the same time, the scraper 7 presses and scrapes the rotating battery core 3. The outer end of the battery core 3 is scraped and lifted. At the same time, a gas flow is ejected from the scraper 7. The gas flow guides the battery core 3 to be transported to the mesh drum 8, completing the preliminary rewinding and disassembly.

[0049] Step 3: The suction force generated by the air shell 10 makes the battery core 3 adhere to the mesh drum 8, and the mesh drum 8 rotates to continue pulling the battery core 3, and the subsequent unwinding and disassembling work of the battery core 3 is completed during the transportation.

[0050] Step 4: The strip of battery core 3 is transported to a position on the mesh tube 8 where there is no suction force, and the battery core 3 will automatically fall off the mesh tube 8, making it convenient for subsequent electrode sheet collection.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
