A tension spring 58 is arranged in the hollow cylindrical tube, and one end of the tension spring is connected to a limiting tube 59 which can slide out of the outside of the hollow cylindrical tube 57. A limiting disk 591 is arranged at one end of the limiting tube 59, and the limiting disk 591 is threadedly connected to the limiting tube 59. The limiting disk is used to limit and install the coiled pole piece sleeved on the outside of the hollow cylindrical tube 57, so that the staff can quickly replace and disassemble the coiled pole piece. The movable plate 41 is arranged at the rear end of the mounting plate 1, and a plurality of guide rods are arranged on the movable plate 41. The guide rods are used to support the movable plate 41 and ensure its smooth sliding, and the guide rods are used to support the smooth sliding of the movable plate 41.

[0030] By setting up the first linear drive 42, it is convenient to adjust the linear horizontal position of the movable plate 41, and when the movable plate 41 moves, the guide rod can allow the movable plate 41 to slide smoothly, so that the two winding rollers 2 installed on one side of the movable plate can be moved linearly horizontally, and each winding roller 2 can be adjusted independently to adapt to the adjustment when the winding pole piece is offset on the winding roller 2.

[0031] See also Figures 3 to 5 As shown, the transmission mechanism 4 also includes a transmission rod 43, a screw rod 44 and a bevel gear pair 45; the transmission rod 43 is arranged on the output shaft of the first linear drive 42; the screw rod 44 is arranged on the moving plate 41 and is threadedly matched with the moving plate 41; the bevel gear pair 45 is arranged on the transmission rod 43, and the bevel gear pair 45 includes a first bevel gear and a second bevel gear, the first bevel gear is arranged at one end of the transmission rod 43, the second bevel gear is arranged at one end of the screw rod 44 and meshes with the first bevel gear, and the first bevel gear and the second bevel gear constitute a reduction mechanism.

[0032] When the first linear drive 42 rotates, the transmission rod 43 drives the bevel gear pair 45 to rotate, and then the bevel gear pair 45 transmits the screw 44 through the first bevel gear and the meshing second bevel gear. Under the deceleration effect of the bevel gear pair 45, the linear horizontal position of the movable plate 41 is adjusted to achieve fine adjustment of the winding roller 2. By setting a pair of first linear drives 42 and their corresponding transmission mechanisms 4, the positions of the two winding rollers 2 can be independently adjusted, thereby improving the adjustment efficiency of the winding roller 2.

A sliding block 56 for sliding the connecting block 51 is arranged on the outside of the positioning rod 55. The sliding block 56 is clearance-matched with the positioning rod 55. The outside of the positioning rod 55 is sleeved with a telescopic spring 592. The two ends of the telescopic spring 592 are respectively fixed to the ends of the positioning rod 55 and the sliding block 56. The telescopic spring 592 is used to drive the connecting block 51 installed on one end of the sliding block to always lean against the outside of the winding roller 2. The connecting block 51 has a pair of and is symmetrically arranged on both sides of a pair of winding rollers 2.

[0034] When the outside of the winding roller 2 is adaptively cleaned, the telescopic force of the telescopic spring drives the cleaning roller 52 rotatably installed at one end of the connecting block 51 to contact the outside of the winding roller 2, thereby achieving adaptive cleaning of the winding pole piece installed on the outside of the winding roller 2 when the winding roller 2 rotates, thereby improving the cleanliness of the winding pole piece set on the outside of the winding roller 2.

[0035] See also Figure 5 and Figure 6 As shown, the cleaning mechanism 5 also includes a circular rod 53 and a flexible cloth 54; the circular rod 53 is rotatably arranged below the connecting block 51; the end of the flexible cloth 54 is detachably arranged on the outside of the circular rod 53, and the flexible cloth 54 is located below the winding roller 2, and a mounting groove for installing the circular rod 53 is opened on the mounting plate 1, and the mounting groove is located below the connecting block 51, and the outside of the circular rod 53 is sleeved and installed between one end of the flexible cloth 54, and the flexible cloth 54 is a microfiber dust-free cloth, whose dense fiber structure can penetrate into the tiny gaps on the surface of the pole piece, absorb and take away dirt, and is not easy to wear during the wiping process and is easy to replace.

[0038] When the second linear driver 61 rotates, the screw rod connected through the coupling can easily drive the moving block 62 to move linearly and horizontally.

[0039] See also Figure 8 and Fig. 9 As shown, the limiting mechanism 6 also includes a limiting block 63, a first rolling roller 64 and a limiting roller 65; a limiting block 63 is arranged on the top of the moving block 62; there are two first rolling rollers 64, which are symmetrically fixedly mounted on the mounting plate 1 and are located above the winding roller 2; the limiting roller 65 is rotatably mounted on the moving block 62, and the limiting roller 65 is close to the side of the first rolling roller 64. The limiting block 63 is located between a pair of second linear drivers 61, and the limiting block 63 is used to limit the transmission direction of the winding pole pieces arranged outside the pair of winding rollers 2, so that the transmission of the winding pole pieces is more stable. The rear end of the mounting plate 1 is also provided with a transmission mechanism 4 for driving the first rolling roller 64 to rotate, and the transmission mechanism 4 is used to control the linear horizontal movement of the first rolling roller 64, so as to facilitate the adjustment of the position of the first rolling roller 64 to adapt to the possible transmission deviation of the winding roller 2.

Subsequently, by starting a pair of second linear drivers 61 arranged opposite to each other, a pair of moving blocks 62 and a limiting block 63 arranged on the top of the moving block 62 can be driven to move horizontally in a straight line. When the moving block 62 moves, the limiting roller 65 installed on one side of the moving block 62 will be rotated to contact the coiled material pole piece transmitted between the coiled material roller 2 and the first rolling roller 64. In this way, through the contact between the limiting roller 65 and the coiled material pole piece, the tension of the coiled material pole piece can be adjusted and controlled, and the transportation stability of the coiled material pole piece can be further improved.
