Title:
COLD-PRESS EXTENSION MECHANISM AND COLD-PRESS DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/190635
Kind Code:
A1
Abstract:
A cold-press extension mechanism (100) comprises a drawing assembly (110) and a press roller assembly (120) disposed along a conveying path of the cold-press extension mechanism. The drawing assembly is used to press two side surfaces of a first portion of a film, and the press roller assembly is used to press two side surfaces of a second portion of the film. The drawing assembly and the press roller assembly have a speed difference therebetween, thus allowing the first portion and the second portion of the film to be rolled in a synchronous manner. Further provided is a cold-press extension device. The cold-press extension mechanism draws and rolls different portions of a film by means of the drawing assembly and the press roller assembly respectively, so as to avoid the problem of uneven rolling resulting from inconsistent film thicknesses or other structural issues, thereby preventing inconsistent extension.
