AI Technical Summary

Technical Problem

In the current production of food packaging bags, excessively high glue viscosity leads to uneven coating, and uneven pressure on the composite roller results in inconsistent thickness, affecting the appearance and product quality. At the same time, the volatilization of organic solvents pollutes the working environment.

Method used

The thickness of the composite material is monitored by components such as electric telescopic cylinder, pressure sensor, force block, spring, and contact roller, and harmful gases are filtered by air extraction component and activated carbon filter plate to ensure material quality and operator health.

Benefits of technology

It enables the monitoring of the uniformity of composite material thickness and the filtration of harmful gases, thereby improving product quality and the safety of the working environment.

Abstract

The utility model relates to the technical field of food packaging bag production equipment, in particular to a compounding machine for food packaging bag production, which comprises a compounding box, and the inner wall of the compounding box is fixedly connected with a heating frame. By arranging the electric telescopic cylinder, the combination plate, the pressure sensor, the force exerting block, the spring, the U-shaped frame, the contact roller and other components, the electric telescopic cylinder pushes the contact roller to make contact with the upper side of a compounded material, when the material is stably wound by a winding piece, the contact roller is in a stable state, and when the compounded material protrudes, the contact roller is in a stable state. The thick part of the contact roller can cause counter-acting force to the contact roller, force is applied to the force applying block by extruding the spring, then data are displayed in the pressure sensor, the pressure sensor can be connected with corresponding alarm equipment, and when a numerical value changes, an alarm can be given out, so that flowing composite plastic can be monitored conveniently; and the quality of the conformed material is ensured.
