Abstract

The invention relates to a lithium strip composite calendaring device and a method. The lithium strip composite calendaring device comprises a feeding device, a rolling calendaring device and a rolling-up device, wherein the feeding device comprises a tinsel unreeling shaft, two lithium strip unreeling shafts and two PE (polyethylene) unreeling shafts, which are sequentially arranged, and the lithium strip unreeling shafts and the PE unreeling shafts are respectively and symmetrically arranged on two sides of tinsel; the feeding device and the rolling-up device further comprise traction devices and a plurality of auxiliary wheels. According to the device and the method, the composite automatic control of a lithium strip and the tinsel is realized, and the quality and production efficiency of products are effectively improved.

Description

Technical field [0001] The invention belongs to the field of metal material composite technology, and relates to a lithium belt composite calendering device and a method thereof. Background technique [0002] At present, the composite materials of lithium and other metals in the battery industry are developing extensively, and the application territory is constantly expanding. However, it is understood that the production method of composite materials is hand-spliced, by simple rolling and then hand-cutting. Its disadvantages are: its work efficiency and yield are relatively low, the quality cannot be guaranteed stably, and the product does not have a complete standard standard configuration, which will affect the production cost. Summary of the invention [0003] In view of this, the purpose of the present invention is to provide a lithium belt composite calendering device and method. [0004] To achieve the above objective, the present invention provides the following technical ...
