Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production, in particular to a novel cutting mechanism. Background Art

[0002] Lithium batteries have the properties of high operating voltage, high specific energy, small size, light weight, long cycle life, low self-discharge rate, no memory effect, and no pollution, so they are used by many power equipment manufacturers. In the lithium battery manufacturing process, wide electrode sheet coils need to be slit before use and cut longitudinally into specified widths. Conventional electrode sheet slitting work is processed and produced by slitting machines, and the slitting knife is an extremely important structure on the slitting machine. The slitting knife needs to be positioned and installed on the moving roller with the knife holder for slitting. Since different lithium batteries have different electrode sheet widths, they can be adjusted and controlled by adjusting the distance between the knife holder and the blade;

[0003] The existing slitting machines need to replace the tool holder and blade according to the different widths of the pole pieces of different lithium batteries. This operation is extremely time-consuming and labor-intensive, and has low precision and is prone to errors, and the adjustment work lacks convenience. Utility Model Content
