Technical Field

[0001] The utility model relates to the technical field of roll film slitting, in particular to a roll film slitting device for a composite current collector of a lithium battery. Background Art

[0002] The composite current collector of lithium batteries is a new type of important internal material of lithium batteries. The composite current collector roll needs to be rewound, and the current collector needs to be slit with a cutter during the rewinding process. It is necessary to ensure the accuracy of the winding edge and to ensure that the composite current collector is not contaminated by the environment. The entire process has very high requirements for the slitting equipment, Class 100 dust-free workshop, and personnel operation.

[0003] According to a publicly disclosed lithium battery composite current collector roll film slitting device (Announcement No.: CN221165295U), in the above application, the supporting plate is fixed by fixing the connecting fastener on one side of the lower knife seat, and the surface of the supporting plate can be used to place the formed roll film. At the same time, the surface fixed pressure plate of the lower knife seat on the other side will adapt to the roll film on the surface of the supporting plate. When the roll film is pushed at a uniform speed by the roller, the pressure plate is placed on the surface of the roll film and pressed onto the roll film by rotating the bolts to prevent the film roll from wrinkling and arching.

[0004] However, in actual use, although the above-mentioned equipment can press out the air bubbles in the roll film through the cooperation of the pressing plate and the supporting plate and then position and cut it, the number of times the bubbles can be pressed out is limited, and in order to ensure that the film is not damaged, the degree of fit and pressure of the extrusion structure will not be too high, and the air bubbles remaining in the roll film cannot be removed more effectively. In view of this, we propose a lithium battery composite current collector roll film slitting device. Utility Model Content

[0025] Furthermore, the connecting plate 408 is fixedly connected to the end of the connecting rod 407, the outer wall of the connecting plate 408 is fixedly connected to the limiting rod 409, the end of the limiting rod 409 is fixedly connected to the limiting block 410, the outer wall of the connecting plate 408 is fixedly connected to the hinged sleeve 411, the outer wall of the hinged sleeve 411 is hinged to the tough plate 412, the end of the tough plate 412 is fixedly connected to the bristles 413, the outer wall of the fixed plate 401 is fixedly connected to the splint 414, and the outer wall of the fixed plate 401 is fixedly connected to the top plate 415.

[0026] In an embodiment of the present invention, the number of degassing components 4 is set up in several groups, and several groups of degassing components 4 are arranged in a linear array on the outer wall of the table 1, so that bubbles in the roll film can be removed more effectively to prevent wrinkles. The sprocket 405 is adapted to the chain 406, so that the sprocket 405 can smoothly drive the chain 406 to rotate, the outer wall of the limit rod 409 is slidably connected to the inner wall of the splint 414, and the limit block 410 is adapted to the splint 414, so that the limit rod 409 can be smoothly displaced on the inner wall of the splint 414.

[0027] In addition, the outer wall of the splint 414 is provided with a wiping component 5, which includes a short plate 501, which is fixedly connected to the outer wall of the splint 414, and the outer wall of the short plate 501 is fixedly connected to a touch rubber rod 502.

Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
