Roll changing device for lithium battery pole piece coating machine

Abstract

The invention discloses a roll changing device for a lithium battery pole piece coating machine. The roll changing device comprises a first supporting plate, a second supporting plate and a base material; a rotating rod is arranged between the first supporting plate and the second supporting plate, the rotating rod penetrates through the first supporting plate through a through opening, a limitingmechanism is arranged between the rotating rod and the first supporting plate, one end of the rotating rod is rotationally connected with the second supporting plate, and the other end of the rotating rod is fixedly connected with a crank; the end, away from the rotating rod, of the crank is sleeved with a rubber sleeve; the outer side of the rotating rod is symmetrically sleeved with a first fixing disc and a second fixing disc, the first fixing disc and the second fixing disc are fixedly connected with the rotating rod, and four motors are fixedly connected with the end, away from the second fixing disc, of the first fixing disc through mounting bases; and four winding drums are arranged between the first fixing disc and the second fixing disc. According to the roll changing device, thewinding drums can be rapidly replaced, halt for a long time is not needed, the production efficiency is greatly improved, meanwhile, the winding drums full of base materials can be conveniently replaced, and operation is quite convenient.

Description

Technical field [0001] The invention relates to a roll changing device for a lithium battery pole piece coating machine, and belongs to the technical field of lithium battery production. Background technique [0002] Lithium batteries are a type of batteries that use lithium metal or lithium alloy as the negative electrode material and use a non-aqueous electrolyte solution. In 1912, the lithium metal battery was first proposed and researched by Gilbert N. Lewis. In the 1970s, M.S. Whittingham proposed and began to study lithium-ion batteries. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become the mainstream. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. A coating machine is needed in the production of lithium batteries. The coating ...
