Conveying guide roller for rapid expanding and setting of high-performance films

Abstract

The invention specifically discloses a conveying guide roller for rapid expanding and setting of high-performance films. The guide roller comprises limit mechanisms, guide-track rollers and a cloth flattening mechanism. The limit mechanisms are coaxially arranged at two ends of the guide-track roller, and limit guide-track grooves are arranged therein. The limit guide-track grooves are provided with groove platforms with height linear variation. The limit mechanisms are fixed on a cloth roll rack. The cloth flattening mechanism is arranged at the outer side of the guide-track roller. Guide-track grooves are symmetrically arranged on the outer circumferential surface of the guide-track rollers. The cloth flattening mechanism comprises a flattening slide block and a push-and-pull mechanism. The push-and-pull mechanism is arranged at one end of the flattening slide block. The flattening slide block is provided with a guide track. Through sliding fit between the guide track and the guide-track grooves, relative sliding of the cloth flattening mechanism on the surface of the guide-track rollers is realized, and the cloth flattening mechanism synchronously rotates with the guide-track rollers. The push-and-pull mechanism slides circumferentially in the limit guide-track grooves to drive the flattening slide block to reciprocate on the guide roller. Thus, cloth expanding crease-removal is realized.

Description

technical field [0001] The invention relates to the field of film processing, in particular to a high-performance film fast tenter setting conveying guide roller. Background technique [0002] The film is usually made of PE film and polyethylene film, and the film is usually produced continuously at high temperature. During the forming process of the film, the heat on the film will be transferred to the guide roller in contact with it, so that the temperature of the guide roller will also increase accordingly. The increase will cause the film to soften and stick to the guide roller; in addition, the film will cool down during the forming process, and the film will shrink to a certain extent while cooling. Shrinkage of the film will lead to unevenness and wrinkling of the film, which will affect the production quality and production efficiency of the film. Therefore, the film needs to be cooled and wrinkled in time. [0003] Application No. 201420611551.7 discloses a film co...
