Aluminum-plastic film packaging rolling machine for soft-pack lithium battery and rolling method for aluminum-plastic film packaging

Abstract

The invention relates to a rolling machine for aluminum-plastic film packaging of soft-pack lithium batteries and a rolling method for aluminum-plastic film packaging, including a supporting base plate, a placing frame, a pressing branch chain and a flattening device. The upper end surface of the middle part of the supporting base plate A placing frame is installed on the top, and a square groove is arranged on the right end and rear side of the placing frame. A pressing branch chain is installed on the front and rear ends of the supporting base plate, and the pressing branch chain is located outside the placing frame, and the leveling device is installed on the placing frame. on the top of the left end; the leveling device includes a leveling support plate, a leveling position push rod, a leveling bracket, a leveling adjustment plate, a leveling sliding column, a height pusher, a smoothing plate, a positive position mechanism and a rolling mechanism. The present invention can solve the problem that the existing aluminum-plastic film on the outer packaging of the soft-packed lithium battery is folded and packaged. After the aluminum-plastic film is folded, it is automatically rolled and scraped to equalize the problem.

Description

Technical field[0001]The invention relates to the technical field of lithium battery production, in particular to a soft-packed lithium battery aluminum-plastic film packaging rolling machine and an aluminum-plastic film packaging rolling method.Background technique[0002]The soft pack lithium battery is a kind of lithium battery. The soft pack lithium battery is just the liquid lithium ion battery covered with a polymer shell. The structure is packaged with aluminum plastic film. In the case of potential safety hazards, the soft pack battery will only Blowing and cracking; in the processing of soft-packed lithium batteries, the aluminum-plastic film of the outer packaging needs to be stamped and formed, and then the battery core is placed in the stamping space. The battery core occupies a quarter of the area of ​​the aluminum-plastic film Left and right, after the battery core is placed, the aluminum-plastic film is folded in half along the middle position to encapsulate the aluminu...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the above problems, the present invention provides a soft-pack lithium battery aluminum-plastic film packaging rolling machine and an aluminum-plastic film packaging rolling method, which can solve the problems existing in the folding and packaging of the existing soft-pack lithium battery outer packaging aluminum-plastic film The rotation point of the aluminum-plastic film will shift when it is folded, the position of the left and right ends of the aluminum-plastic film will deviate when it is packaged, and it will not be possible to automatically roll and scrape the aluminum-plastic film after it is folded; it can realize the aluminum-plastic film It has the function of neat folding and scraping, and the rotation point of the aluminum-plastic film will not shift when it is folded. There is no deviation in the position of the left and right ends of the aluminum-plastic film when it is packaged. Advantages of rolling scraping
