AI Technical Summary

Technical Problem

In the existing film production line's transverse stretching and pre-cutting process, the material roller is only placed on the inclined groove of two support rods, which results in insufficient stability during the transverse stretching of the film, affecting the film's conveying and cutting quality.

Method used

A guide roller mechanism for transverse pre-cutting in a film production line is designed, including a stretching component and a feeding component. The axial movement of the material roller is restricted by the engagement of the annular protrusion on the holding block with the annular groove of the fixed sleeve. The position of the material roller is adjusted by a motor-driven screw and sliding block. Combined with the tension adjustment component, the film is prevented from deviating, ensuring the continuity and stability of the feeding process.

Benefits of technology

It effectively restricts the axial movement of the material roller, ensuring the continuity and stability of the film feeding process, preventing the material roller from coming off, and ensuring the smooth conveying and cutting quality of the film.

Abstract

The utility model discloses a transverse stretching and pre-cutting guide roller mechanism for a thin film production line, and belongs to the technical field of thin film production. The stretching device mainly comprises a stretching assembly which comprises a supporting frame. The discharging assembly comprises a bottom plate, two sets of supports are installed on the bottom plate, and a certain distance is formed between the two sets of supports; mounting grooves are formed in the support in a penetrating mode, a material roller is placed between the two mounting grooves, roller shafts are arranged at the two ends of the material roller, and containing grooves matched with the roller shafts are formed in the bottom faces of the inner walls of the mounting grooves. Roller shafts at the two ends of the material roller are sleeved with fixing sleeves, annular grooves are formed in the fixing sleeves, the support is in threaded connection with two sets of screws, one ends of the two sets of screws are in bearing connection with pressing blocks, and annular protruding parts matched with the grooves are installed on the pressing blocks. According to the guide roller mechanism for transverse stretching and pre-cutting of the thin film production line, it is guaranteed that the material roller is stably placed and discharged through the discharging assembly, disengaging is avoided, and rotation is stable.
