A first fixed circular block 2 is fixedly connected to one side of the connecting shaft 1. A plurality of fixed plates 3 are arranged in a ring array on one side of the first fixed circular block 2. Mounting blocks 4 are fixedly connected to one side of each of the fixing plates 3. A through hole is opened on the surface of the mounting block 4. A movable sleeve 5 is slidably connected to the inner cavity of the through hole. A second fixed circular block 6 is slidably connected to the inner cavity of the movable sleeve 5. The second fixed circular block 6 is disposed in the inner cavity of the through hole. A first spring 7 is sleeved on the surface of one end of the second fixed circular block 6 and is disposed on the inner wall of the movable sleeve 5. A first fixed rod 8 is fixedly connected to the inner cavity of the second fixed circular block 6. A sliding rod 9 is provided at one end of the first fixed rod 8 and the inner cavity of the sliding rod 9 is slidably connected to the surface of the first fixed rod 8. A second spring 10 is fitted onto the surface of the second fixed block 6, and the other end of the second spring 10 is fixedly connected to the inner cavity of the second fixed block 6. One end of the sliding rod 9 is fixedly connected to a first movable coupling 11. A first groove is formed at one end of the second fixed block 6, and a plurality of rollers 12 are arranged in the inner cavity of the first groove. A movable block 13 is arranged in the inner cavity of one end of the second fixed block 6, and a second groove is formed at one end of the movable block 13, with the rollers 12 in contact with the second groove. A second fixed rod 14 is fixedly connected to the inner cavity of the movable block 13, and a second movable coupling 15 is slidably connected to the surface of the second fixed rod 14.

[0023] Specifically, a fixed plate 17 is fixedly connected to one side of the mounting block 4. The surface of the fixed plate 17 is provided with several sliding grooves.

When the internal structure of the mounting block 4 is damaged, the rotation baffle 19 can be triggered by rotating the rotating disk 21, thereby making it easy to take out the internal components of the mounting block 4 for repair or replacement, which improves the ease of operation.

[0025] Specifically, threaded holes are provided on both sides of the surface of several fixing plates 3, and bolts 22 are threadedly connected to the inner cavity of the threaded holes.

[0026] In this embodiment, the fixing plate 3 can be firmly fixed in the designated position by the use of threaded holes and bolts 22, ensuring its stability and reliability during operation.

[0027] Specifically, a kneading wheel 23 is fixedly connected to one side of the movable circular block 13.

[0028] In this embodiment: by setting the flattening roller 23, the two ends of the battery cell 25 are evenly flattened, which effectively eliminates the unevenness or minor defects on the end face of the battery cell 25, thereby improving the assembly accuracy and overall performance of the battery cell 25, and ensuring that the battery cell 25 can better cooperate with other components in the subsequent production process.

[0029] Specifically, a center pin 24 is fixedly connected to the central axis of the mounting block 4, a battery cell 25 is provided at one end of the center pin 24, a support frame 26 is provided on the bottom surface of the battery cell 25, and a flattening wheel 23 is rotatably connected to the surface of one end of the battery cell 25.

[0030] In this embodiment: by setting the flattening roller 23, during the flattening process of the end of the center needle 24, the flattening roller 23 is inserted into the center hole of the battery cell, so that the flattening roller 23 can play a positioning role, ensuring that each bolt 22 rotates relative to the central axis of the center needle 24, and ensuring the flattening quality of the end of the center needle 24.

[0031] Specifically, a sliding groove is provided on one side of the mounting block 4, and a movable block 27 is slidably connected to the inner cavity of the sliding groove, and the movable block 27 is fixedly connected to the surface of the movable sleeve 5.

[0032] In this embodiment, the movable block 27 plays a key role in disassembling the internal structure of the device. Pulling the movable block 27 can drive the movable sleeve 5 to move within the cavity of the mounting block 4, thereby providing greater flexibility and convenience for the disassembly process.

[0033] The working principle and usage process of this utility model are as follows: The user fixes the connecting shaft 1 to the output end of the kneading machine, then places the battery cell 25 on the surface of the inner cavity of the support frame 26, aligns one end of the center pin 24 with the central axis of the battery cell 25, and fixes the connecting shaft 1 to the first fixed round block 2 on one side. A fixing plate 3 is provided on the surface of the first fixed round block 2, and threaded holes are opened at both ends of the fixing plate 3. Bolts 22 are threaded into the inner cavity of the threaded holes, which can fix the mounting block 4 to the surface of the first fixed round block 2 and facilitate the disassembly and maintenance of the mounting block 4. At this time, the kneading machine is started, which drives the connecting shaft 1 to rotate, so that the kneading wheel 23 can rotate to achieve kneading of the battery cell 25. Over time, the kneading roller 23 may develop surface damage and unevenness, requiring replacement. To replace it, the user pushes the movable block 27 on the surface of the mounting block 4. The movable block 27 is fixedly connected to the movable sleeve 5, which slides within the inner cavity of the mounting block 4. At this point, the movable sleeve 5 no longer obstructs or presses the roller 12. The user then pulls the movable round block 13, causing the roller 12 to enter the inner cavity of the mounting block 4 through the movement of the second groove in the movable round block 13. The movable round block 13 can then be removed. During installation, the kneading roller 23 moves the movable round block 13 within the inner cavity of the mounting block 4 and the second fixed round block 6. As the movable circular block 13 moves within the inner cavity of the mounting block 4, it causes the second movable connector 15 to press against the inner cavity of the second fixed circular block 6. At this time, the inner cavity of the second movable connector 15 and the inner cavity of the sliding rod 9 slide on the surfaces of the second fixed rod 14 and the first fixed rod 8, respectively. Ultimately, the second movable connector 15 presses against the first movable connector 11. When the movable circular block 13 moves, the surface of one end of the movable circular block 13 causes the roller 12, which was originally in the groove of the second fixed circular block 6, to move outwards. The roller 12 moves to the inner wall of the movable sleeve 5. When the surface of one end of the movable circular block 13 contacts the second fixed circular block 6, the roller 12, having no obstruction, will slide... The material falls into the first groove of the second fixed round block 6 and the second groove of the movable round block 13, thus stabilizing the movable round block 13. The second spring 10 and the third spring 16 mainly play the role of elastic reset, so that the second movable coupling 15 and the first movable coupling 11 can return to their original state after being squeezed, making it convenient to continue working next time. When it is necessary to repair or replace the movable sleeve 5, the second fixed round block 6 and its internal structure, the rotating disk 21 provided on one side of the mounting block 4 is rotated to retract the rotating baffle 19, so that the internal structure of the mounting block 4 can be taken out for repair and replacement. When the rotating baffle 19 is in the closed state, it mainly plays the role of blocking the internal mechanism of the mounting block 4.

[0034] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
