Problems solved by technology

Due to the frequent occurrence of air leakage during the blowing process of plastic bag production, the continuous production of plastic bags cannot be carried out. Therefore, in view of the above status quo, it is urgent to develop an instantaneous air supply device for bag making machines to overcome the current practical application. insufficient

Abstract

The invention relates to the technical field of plastic bag production, in particular to an instantaneous air supply device for a bag making machine, comprising a bottom plate, an expansion degree detection mechanism and an air supply mechanism; two side plates are symmetrically fixed on the left and right sides of the bottom plate, A top plate is fixedly installed on the top of the side plate, two first pressure rollers are arranged symmetrically above the bottom plate, and two second pressure rollers are symmetrically arranged below the top plate; the expansion degree detection mechanism is fixedly installed on a side plate The inner side; the air supply mechanism is arranged on a side plate. The invention installs an expansion degree detection mechanism on the inner side of a side plate to detect the expansion degree of the plastic bag when blowing air. When the expansion degree of the plastic bag does not meet the requirements, the air supply mechanism is started to replenish the plastic bag. Avoid air leakage of plastic bags and ensure continuous production of plastic bags.

Description

technical field [0001] The invention relates to the technical field of plastic bag production, in particular to an instantaneous air supply device for a bag making machine. Background technique [0002] Plastic bags are bags made of plastic (commonly used plastics include polypropylene, polyester, nylon, etc.) as the main raw material. They are indispensable items in people's daily life and are often used to hold other items. It is widely used because of its advantages of cheapness, light weight, large capacity and easy storage, but its production and use are banned by some countries due to the disadvantages of extremely long degradation cycle and difficult disposal of plastic bags. [0003] From the perspective of the process of making plastic bags, the incoming material is generally two layers of film stacked together in a roll, and the side edge width of one layer of film is wider than that of the other layer. When making plastic bags, glue is applied to the wide layer. ...
