Roll replacing mechanism

Abstract

The invention discloses a roll replacing mechanism. The mechanism comprises a first material rolling shaft and a second material rolling shaft, the first material rolling shaft and / or the second material rolling shaft are / is sleeved with multiple material rolls, when one of the first material rolling shaft and the second material rolling shaft is an unrolling shaft, the other one is a preparing shaft. When the unrolling shaft is located on the unrolling station, and the unrolled old material roll is about to be used up, the new material roll, on the unrolling station, of the preparing shaft isconnected to a material belt of the old material roll and enables the preparing shaft to become the new unrolling shaft, and the roll replacing efficiency is improved.

Description

technical field [0001] The invention relates to a roll changing mechanism, which belongs to the technical field of automation equipment. Background technique [0002] In the battery production process, it is often necessary to use coiled materials, such as pole pieces, separators and other materials, which are usually used in the form of coiled materials, and then enter the machine after being rotated and discharged by the material reel. When the roll material roll is used up, it is necessary to start the spare roll to complete the roll change. The existing automatic roll change mechanism mostly adopts two sets of suction cups on the left and right, after absorbing the material of the material roll and the stock roll, cutting and then receiving the material. This type of roll changing mechanism has a complex structure and takes up a lot of space; when receiving materials, tapes must be prepared to fit the tail of the old material roll and the head of the new material roll. ...

AI Technical Summary

Problems solved by technology

This type of roll changing mechanism has a complex structure and takes up a lot of space; when picking up materials, tapes must be prepared to fit the tail of the old roll and the head of the new roll, so there are many operating procedures, the roll change is troublesome, and the efficiency is low.

At the same time, only one set of spare rolls can be stored, and new rolls need to be replaced after each roll change. The stocking is insufficient and the roll change efficiency is low.
