Description

Film selvedge flattening mechanism

Technical Field

The utility model relates to the technical field of conductive film production, in particular to a film clamping and flattening mechanism.

Background

The conductive film is used as a high polymer material with metal plated on the surface, is widely applied to lithium ion batteries, and is mainly used as a battery current collector. In the film production process, the operation of rolling is needed after the film is formed, and the film is required to be cooled by a cooling roller set before rolling. However, when the film passes through the cooling roll, problems such as large-area edge shrinkage and bubble sticking occur at the positions of both side edges, which directly results in an excessively high rejection rate of the film. In order to solve the problem of film wrinkling, the traditional method in the industry adopts an arc roller device, and the film is strongly flattened by utilizing the arc shape with high middle and low two sides of the arc roller. However, in the process of flattening the film by the curved roll, there are mainly two disadvantages: on one hand, due to the inherent arc characteristic of the arc roller, the height difference exists in the axial direction, so that the transverse stress of the film is uneven, the transverse deformation of the product is uneven, and the consistency of the product in the transverse performance is finally influenced; on the other hand, in the process of flattening the film by using the arc roller, the film must be entirely contacted with the roller surface of the arc roller, so that the film surface of the film is inevitably damaged, and the quality of the film is further affected.

The existing mode is to hold and guide the two sides of the film through the edge clamping assemblies symmetrically arranged at the two ends of the guide roller, so that the edge shrinkage rate is reduced. However, for such clamping mode, the film cannot be stably clamped, and the film is difficult to be placed between the clamping wheels by the existing clamping wheels, so that the clamping wheels are required to be detached for use, a large amount of time is wasted in the process, and the production efficiency is reduced.
