Film material compounding device

Abstract

The invention relates to a film material compounding device. The film material compounding device comprises a first compression roller mechanism, a second compression roller mechanism and a first adjusting mechanism, wherein the first compression roller mechanism comprises a base and a first compression roller rotationally arranged on the base around the axis of the first compression roller, the second compression roller mechanism comprises a fixed support, a swing seat rotationally connected to the fixed support around a rotating axis and a second compression roller rotationally connected tothe swing seat around the axis of the second compression roller, the second compression roller and the first compression roller are arranged in the first direction perpendicular to the axial directionof the first compression roller so as to abut against the two sides of a film material correspondingly, the rotating axis is perpendicular to the first direction and the axial direction of the firstcompression roller, and the first adjusting mechanism is connected with the fixed support and the swing seat and can apply acting force enabling the swing seat to rotate around the rotating axis. Andtherefore, the swing seat can be driven to rotate around the rotating axis through the first adjusting mechanism, then the second compression roller is driven to rotate around the rotating axis relative to the first compression roller, the second compression roller is parallel to the first compression roller, the compounding effect of the film material is favorably ensured, and the product qualityis improved.

Description

technical field [0001] The invention relates to the technical field of membrane material processing equipment, in particular to a membrane material composite device. Background technique [0002] At present, the composite processing of membrane materials is more and more widely used in industrial production. For example, in the production of batteries, it is necessary to use a membrane material composite device to composite the anode electrode, cathode electrode and diaphragm to form a composite film. Generally, the following two composite processes are used in the production of batteries: first, the anode pole piece and the separator are combined to form the first composite film, and the cathode pole piece and the separator are combined to form the second composite film, and then the first composite film is formed according to the battery technology. The film and the second composite film are wound to form a bare cell. The second is to first compound the anode pole piece, ...

Problems solved by technology

[0004] Based on this, it is necessary to address the fact that in the prior art, due to factors such as assembly and manufacturing errors, the central axes of the two pressure rollers used to laminate the membrane materials in the membrane material lamination device are easily offset and not parallel to each other, which seriously affects the lamination process. effect, reduce the problem of product quality, and provide a membrane composite device that improves the above defects
