[0002] An electrode is a sheet-like device used to conduct current or electrical signals. It is often used as a component of an electrode and is widely applied in medical, industrial, and electronic fields.

[0003] In the existing technology, tabs are often used in conjunction with electrode sheets. Both are important components of lithium batteries. After the electrode sheet completes the ion reaction, the current is conducted to the external load through the tab. Together, they determine the battery's internal resistance and energy efficiency. When manufacturing electrode sheets, electrode coatings are generally first applied to both sides of the electrode sheet, and then the desired finished electrode sheet is obtained by rolling. Rolling is generally performed using a rolling press.

[0004] However, the pressure roller of a roller press is a very critical and important component. Currently, the pressure roller structure of roller presses generally adopts an integral roller sleeve baked on the roller shaft. The roller sleeve is a wear part, and its main failure mode is roller surface wear and peeling. After the roller sleeve fails, the roller press needs to be disassembled, the old pressure roller is removed, and a new pressure roller is replaced, or it can be repaired by welding on site and reused. However, the downtime is long, the welding quality is difficult to guarantee, the cost is high, and it directly affects the overall machine operating rate. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1: Please refer to Figures 1 to 11 This utility model provides a technical solution: a wood material preparation component for extending lithium electrode tabs of high-pressure compacted material. A positioning groove 10 is opened on one side surface of the roller sleeve 9, and a positioning slide rail 11 is fixed on the other side surface of the roller sleeve 9. The roller sleeve 9 is connected to the pressure roller 7 by snap-fit ​​and is limited by the positioning mechanism to fix the roller sleeve 9 on the surface of the pressure roller 7. Therefore, the roller sleeve 9 can be removed from the surface of the pressure roller 7 without welding or tools, which improves the maintenance efficiency. A limiting ring groove 12 is opened on the inner wall of the roller sleeve 9 near the end. A limiting ring block 17 is movably provided on the inner wall of the limiting ring groove 12. The limiting ring block 17 limits the roller sleeve 9 so that the roller sleeve 9 cannot move.

[0031] A pressure roller 7 is movably mounted on the inner surface of the worktable 1. A drive sleeve 15 is movably mounted on the surface of the pressure roller 7. A spring 14 and a limiting sleeve 21 are movably mounted inside the drive sleeve 15. A first toothed block 13 is fixed to the inner wall of the drive sleeve 15 near the port. A second toothed block 22 is fixed to one end of the limiting sleeve 21. Pushing the limiting sleeve 21 toward the center of the pressure roller 7 moves the first toothed block 13 and the second toothed block 22 so that they are no longer stuck. At this time, the limiting between the drive sleeve 15 and the pressure roller 7 disappears and can rotate.

[0032] Based on Embodiment 1, the pressure roller 7 is provided with two sets of rollers arranged symmetrically. One set of pressure roller 7 has a motor 4 fixed at its end and a transmission belt 3 movably provided at its end. The transmission belt 3 connects the two sets of pressure roller 7. The inner side of the worktable 1 is provided with an unwinding roller 5 and a winding roller 8. An electrode sheet 2 is sleeved on the outer surface of the unwinding roller 5. The pressure roller 7 is located between the unwinding roller 5 and the winding roller 8. The roller sleeve 9 is movably provided on the outer surface of the pressure roller 7.

[0033] The roller sleeve 9 is provided in multiple sets, which are distributed in a circumferential manner. This component divides the roller sleeve 9 into multiple identical parts. When the roller sleeve 9 is damaged, only the damaged part of the roller sleeve 9 needs to be replaced, instead of replacing the entire roller sleeve 9, which reduces the working cost. The positioning groove 10 corresponds to the positioning slide rail 11 and is movably locked. The inner wall diameter formed by the multiple sets of roller sleeves 9 is the same as the maximum diameter of the drive sleeve 15.

[0034] A transmission rod 19 is fixed to one side of the limiting ring block 17, and a groove 20 is formed on the other side of the limiting ring block 17. A protrusion 18 is fixed to the side of the pressure roller 7. The protrusion 18 corresponds to the groove 20 and is movably engaged. A transmission groove 6 is formed on one side of the drive sleeve 15. The transmission groove 6 corresponds to the transmission rod 19 and is movably engaged. When the drive sleeve 15 is rotated, the transmission rod 19 is engaged in the transmission groove 6. The transmission groove 6 is arc-shaped, with its upper end close to the outside of the drive sleeve 15 and its lower end close to the axis of the drive sleeve 15. Therefore, rotating the drive sleeve 15 will drive the transmission rod 19 to move towards the axis of the drive sleeve 15. However, since the protrusion 18 and the groove 20 are engaged with each other, the limiting ring block 17 will not follow the rotation of the drive sleeve 15 but will move in a straight line. Therefore, the limiting ring block 17 will move downward towards the axis of the drive sleeve 15, so that the limiting ring block 17 is no longer engaged in the limiting ring groove 12.

[0035] A limiting groove 16 is formed on the outer surface of the end of the pressure roller 7. A limiting block 23 is fixed on the inner wall of the limiting sleeve 21. The limiting groove 16 and the limiting block 23 correspond to each other and are movably locked. The first tooth block 13 and the second tooth block 22 correspond to each other and are movably locked. The locking of the limiting block 23 and the limiting groove 16 prevents the limiting sleeve 21 from rotating on the surface of the pressure roller 7. Furthermore, the locking of the first tooth block 13 and the second tooth block 22 prevents the drive sleeve 15 from rotating on the surface of the pressure roller 7.

[0036] The specific solution is as follows: Since the roller sleeve 9 is not a whole but is divided into multiple groups of the same size, when a part is damaged, the motor 4 is turned off to stop the two groups of pressure rollers 7. Then, the limiting sleeve 21 is pushed towards the center of the pressure roller 7. The movement of the limiting sleeve 21 will squeeze the spring 14, and at the same time, the first tooth block 13 and the second tooth block 22 will no longer be stuck. At this time, the limit between the drive sleeve 15 and the pressure roller 7 disappears and can rotate.

[0037] Rotating the drive sleeve 15 causes the transmission rod 19 to be engaged in the transmission groove 6, which is arc-shaped with its upper end close to the outside of the drive sleeve 15 and its lower end close to the axis of the drive sleeve 15. Therefore, rotating the drive sleeve 15 will cause the transmission rod 19 to move toward the axis of the drive sleeve 15. Since the protrusion 18 and the groove 20 are engaged with each other, the limiting ring block 17 will not follow the rotation of the drive sleeve 15 but will move in a straight line. Therefore, the limiting ring block 17 will move downward toward the axis of the drive sleeve 15, so that the limiting ring block 17 is no longer engaged in the limiting ring groove 12.

[0038] At this point, the limiting ring block 17 loses its limiting effect on the roller sleeve 9. The damaged part of the roller sleeve 9 can be pushed to move horizontally to the left or right until it is separated from the other parts of the roller sleeve 9. The same applies to the properly assembled roller sleeve 9.

[0039] This component divides the roller sleeve 9 into multiple identical parts. When the roller sleeve 9 is damaged, only the damaged part of the roller sleeve 9 needs to be replaced, instead of replacing the entire roller sleeve 9, which reduces the labor cost. At the same time, the roller sleeve 9 is connected to the pressure roller 7 by snap-fit ​​and is limited by the positioning mechanism to fix the roller sleeve 9 on the surface of the pressure roller 7. Therefore, the replacement of the roller sleeve 9 does not require welding or other methods, and the roller sleeve 9 can be removed from the surface of the pressure roller 7 without the use of tools, which improves the efficiency of maintenance.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
