Replaceable piece wrapping roller for piece wrapping machine

Abstract

The invention discloses a replaceable piece wrapping roller for a piece wrapping machine, and relates to the technical field of piece wrapping machines. The replaceable piece wrapping roller comprises a roller shaft and a roller body; rotating shafts are fixed at two ends of the roller shaft; a plurality of adjusting holes are formed in one end of the roller shaft; fixing rods in one-to-one correspondence with the adjusting holes are hinged to the peripheral side surfaces of the roller shaft; multiple pairs of sliding groove openings are formed in the circumferential side face of the roller shaft; each pair of sliding groove openings are in one-to-one correspondence with the adjusting holes and are communicated with the adjusting holes; each fixing rodis hinged with two first connecting rods; one end of each first connecting rod is hinged to the peripheral side of the roll shaft; adjusting rods are in clearance fit with the interiors of the adjusting holes; second connecting rods are hinged to the adjusting rods; the second connecting rods are hinged to the lower surfaces of the fixing rods; fixing grooves matched with the fixing rods are arrayed in the inner wall of the roller. The roller shaft and the roller are arranged to be of a split structure, so that the problem that an existing piece wrapping roller is inconvenient to replace is solved. The roller and the roller shaft are detachably connected, so that the roller can be independently replaced and machined, so that the problem that an existing piece wrapping roller is high in machining cost is solved.

Description

technical field [0001] The invention belongs to the technical field of wrapping machines, in particular to a replaceable wrapping roller for wrapping machines. Background technique [0002] In the battery production process, there is a process of assembling the positive plate, negative plate, and separator paper into an electrode group. The separator paper is sandwiched between the positive plate and the negative plate, so it is usually called "wrapping sheet" in the industry. Or "pack board" process. [0003] The battery wrapping machine is mostly fully automated, and the wrapping process is completed by a pushing mechanism and a paper feeding mechanism. The pushing mechanism of the wrapping machine includes a plate guide rail and a push plate device that pushes the plate along the plate guide rail. In order to wrap the polar plate and the cardboard fed by the paper feeding mechanism, a pair of wrapping rollers are installed at the end of the guide rail, and the pushing pl...

Problems solved by technology

[0006] The purpose of the present invention is to provide a replaceable wrapping roller for wrapping machine, which solves the problem of inconvenient replacement of existing wrapping rollers by setting the roller shaft and the roller in a separate structure

By realizing the detachable connection between the roller and the roller shaft, the roller can be replaced and processed separately, which solves the problem of high processing cost of the existing wrapping roller
