Problems solved by technology

[0004] Aiming at the deficiencies of the existing technology, the present invention provides a lithium battery pole piece rolling mill, which solves the problem that the traditional pole piece is easily affected by the tension force when rolling, and when the tension force is too large, the pole piece will be transported It is inconvenient and affects production efficiency. If the tension is too small, it is prone to bending, slack, and even wrinkles. It is not conducive to subsequent hot rolling and rolling, which seriously affects processing efficiency and quality, and reduces the problem of performance.

Abstract

The lithium battery pole piece rolling mill comprises a machine body, a pressing roller and hot rolling devices, the pressing roller is arranged in the machine body and located in the center, the hot rolling devices are arranged in the machine body and located on the two sides of the pressing roller, a tensioning device is arranged in a box body and close to the end, and the hot pressing roller is arranged in the box body and close to the center. And the preheating device is arranged in the box body and close to the hot pressing roller, the bulldozing device is arranged at the end, away from the inner wall of the box body, of the supporting piece, and the pressing device is arranged on the surface of the supporting piece and close to the bulldozing device. According to the lithium battery pole piece rolling mill, the elastic tensioning effect is achieved, bi-directional and elastic tensioning can be conducted on a pole piece, the situation that the pole piece is affected by too large or too small tensioning force is not prone to occurring, and the situations of bending, loosening and wrinkling are not prone to occurring, so that subsequent hot rolling and rolling are facilitated, and the use performance is improved.

Description

technical field [0001] The invention relates to the technical field of pole piece processing equipment, in particular to a lithium battery pole piece rolling machine. Background technique [0002] As lithium-ion batteries are used more and more widely, people's requirements for the quality of batteries are also getting higher and higher. The production process of lithium battery pole pieces includes mixing, coating, rolling, slitting, tab welding and other processes. This process is the basis for ensuring the performance of lithium batteries. In the battery production process, the rolling of the pole piece is a very important production process. Therefore, it is required to ensure that the thickness of the rolled pole piece is consistent during the continuous production process of the battery pole piece. In the rolling process of the lithium battery pole piece, the tension performance of the pole piece and the hot rolling effect are one of the two important factors affectin...
