AI Technical Summary

Technical Problem

Due to the different tension of films of different materials, the film and PE film are not tightly bonded during hot pressing, and wrinkles are prone to occur after hot pressing, which affects the preparation effect of the PE composite film.

Method used

A high-pressure hot-pressing composite structure of a multi-layer PE film is designed, including a tension assembly and a hot-pressing assembly. The tension assembly adjusts the tension force of the tension roller through the cylinder and the air pump to ensure the appropriate film tension. The hot press assembly adjusts the position of the hot press plate by adjusting the threaded rod and nut to prevent film damage.

Benefits of technology

By adjusting the tension force and the position of the hot press plate, ensure that the film is closely fit during the hot pressing process, avoid wrinkles, and improve the hot press quality and the suitability of the composite film.

Abstract

The utility model discloses a high-pressure hot-pressing composite structure of a multilayer PE film, which comprises a box body and a tension assembly of the box body, the tension assembly comprises a guide rod fixedly arranged in the box body, a U-shaped frame is arranged on the guide rod in a sliding manner, a tensioning roller is rotatably arranged in the U-shaped frame, a guide roller A is rotatably arranged above the tensioning roller, and a guide roller B is rotatably arranged above the guide roller A; the lower part of the U-shaped frame is fixedly connected with an air cylinder, the air cylinder is provided with a pressure gauge, and one side of the air cylinder is fixedly provided with an air pump. According to the high-pressure hot-pressing composite structure of the multi-layer PE film, air pressure generated by the air pump is conveyed into the air cylinder through the air conveying pipe, so that the U-shaped frame at the end of the air cylinder is driven to move, the pressure in the air cylinder is adjusted through the pressure gauge on the air cylinder, and then the tensioning force of the tensioning roller can be observed; and therefore, the tension degree of the film can be adjusted according to different materials, and the hot pressing quality of the film is guaranteed.
