Deformable roller passing structure capable of automatically adjusting tension of pole piece

Abstract

The invention discloses a deformable roller passing structure capable of automatically adjusting tension of a pole piece, which comprises an inner roller and an outer roller, a center shaft concentric with the inner roller is arranged in the inner roller, and the outer roller is composed of at least two sections of arcs forming a cylindrical structure; a tension adjusting mechanism connected with the inner roller is connected to the center shaft and comprises at least two guide rods correspondingly connected with the at least two sections of arcs and connecting frames connected to the inner roller and the center shaft and corresponding to the guide rods; and the guide rods are connected to the corresponding connecting frames in a sliding mode. The guide rods are displaced in the axial direction through the magnetic force of an electromagnetic rings and the elastic effect of springs, so that the diameter of the outer roller is adjusted, and the problem that the edge of supplied foil in the width direction is loosened in lithium battery piece production is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of tension adjustment, and in particular relates to a deformable roller structure for automatically adjusting the tension of pole pieces. Background technique [0002] In the production process of power batteries, during the operation of coating machines, rolling, winding and other equipment, the tension of the incoming lithium battery foil is uneven, and one end of the incoming foil is loose in the width direction and the other is tight, resulting in frequent needs in production. Adjust the levelness and parallelism of the passing rolls of the equipment, but the degree of tension unevenness of each roll is different, and it is necessary to repeatedly adjust the installation accuracy of the passing rolls of the equipment. This operation is cumbersome, time-consuming and laborious, and cannot be realized for the actual situation of uneven tension of each roll auto-adjust. Contents of the invention [0003]...
