Plasticizing stretcher with anti-deviation structure

By setting an anti-deviation component on the plasticizing stretching machine, and using a limit plate and guide plate in conjunction with a servo motor to drive the lead screw to adjust the distance, the problem of film deviation on the wrapping shaft is solved, achieving stable film stretching and winding, and adapting to the limiting requirements of films of different widths.

AI Technical Summary

Technical Problem

Existing plasticizing and stretching machines lack anti-deviation structures during the film winding process on the wrapping shaft, causing film position deviation, affecting normal plasticizing, stretching, and winding, and causing inconvenience to users.

Method used

An anti-deviation component, including a limiting plate and a guide plate, is installed on the plasticizing stretching machine. The distance between the limiting plate and the guide plate is adjusted by driving the forward and reverse lead screws with a servo motor to achieve anti-deviation limiting of the film.

Benefits of technology

It effectively prevents the film from shifting on the wrapping shaft, ensures normal stretching and winding, adapts to the limiting requirements of films of different widths, and improves the stability of the preparation operation.

Abstract

The utility model relates to the technical field of plasticization stretching machines, in particular to a plasticization stretching machine with an anti-deviation structure, which comprises a plasticization stretching machine main body, a bypassing shaft and a surrounding shaft, a bottom plate is arranged on the plasticization stretching machine main body, and an anti-deviation component is arranged on the bottom plate. The anti-deviation assembly comprises two limiting discs which sleeve the surrounding shaft and are in sliding connection with the surrounding shaft and two guiding discs which sleeve the bypassing shaft and are in sliding connection with the bypassing shaft, connecting rods are fixedly installed between the corresponding limiting discs and the corresponding guiding discs, vertical plates are fixedly installed at the bottoms of the connecting rods, threaded sleeves are fixedly installed on the vertical plates, and the threaded sleeves are fixedly connected with the limiting discs. The anti-deviation assembly further comprises a servo motor, a forward lead screw is fixedly installed at the tail end of an output shaft of the servo motor, a reverse lead screw is fixedly installed at the tail end of the forward lead screw, and the forward lead screw and the reverse lead screw penetrate through the corresponding threaded sleeves and are in threaded connection with the threaded sleeves. The device can prevent the film from deviating, facilitates processing operation, and is convenient to use.
