AI Technical Summary

Technical Problem

Existing plastic bag cutting and pressing devices pose a risk of manual bag placement and make it difficult to effectively separate the bag material before and after cutting, resulting in difficulties in sorting and unloading goods.

Method used

A cutting device including a cutting and conveying mechanism, a punching mechanism, and a leveling mechanism was designed. The device uses a slanted blade and a bag clamping assembly to achieve automated clamping, cutting, and sorting of plastic bags. Through the cooperation of slanted cutting and leveling pressure bars, the waste material and the finished product are clamped on the same horizontal plane, and the waste material falls automatically after cutting.

Benefits of technology

It enables safe and automated cutting and sorting of plastic bags, avoiding the dangers of manual contact and improving production efficiency and safety.

Abstract

This utility model discloses a cutting device for PE plastic bag production, relating to the field of plastic bag production technology. It includes a cutting and conveying mechanism, with a punching mechanism connected to the upper end of the mechanism for cutting plastic bags. One end of the punching mechanism is connected to a leveling mechanism, and another end of the cutting and conveying mechanism is connected to a bag feeding mechanism. This utility model solves the problems of the inherent dangers of manually placing plastic bags in existing plastic bag cutting and pressing devices, and the difficulty in effectively separating the finished plastic bags from the waste material. By using a slanted blade in the punching mechanism, combined with the reserved space for the bag feeding mechanism and the leveling mechanism, the waste plastic bags and the finished plastic bags will interlock on the same horizontal plane after cutting. When moved to the reserved space, the waste material cannot interlock with the finished product and will fall due to lack of clamping. The cutting and conveying mechanism eliminates the need for manual contact with the cutting space at the lower end of the lifting pressure plate.
