AI Technical Summary

Technical Problem

In the current production process of environmentally friendly paper bags, the negative pressure adsorption method requires high paper flatness. Wrinkles or uneven thickness on the paper bag surface can easily cause the glue coating position to shift. In addition, water-based glue is easy to volatilize under negative pressure, which affects the glue coating quality.

Method used

The system employs a structure consisting of a belt conveyor, an operating table, a vertical cylinder, a horizontal movement component, and a paper positioning component. The vertical cylinder drives the glue applicator head to descend, while the horizontal movement component drives the glue applicator horizontally. Springs reduce the impact force on the glue applicator head, and the paper positioning component maintains the stability and flatness of the paper, preventing negative pressure adsorption.

Benefits of technology

It improves the quality of adhesive coating, prevents paper deformation and adhesive position deviation, avoids the evaporation of water-based adhesives, and achieves a stable adhesive coating process for paper.

Abstract

This utility model relates to the technical field of paper bag production equipment and discloses an environmentally friendly paper bag production and processing device, including a belt conveyor. Limiting components are provided on both sides of the bottom end of the belt conveyor. An operating table is fixedly provided at the top of the belt conveyor, and a aligning component is provided at the bottom of the operating table. A mounting frame is provided inside the operating table, and a transverse component is provided at the top of the operating table to drive the mounting frame to move horizontally. A vertical cylinder is fixedly provided inside the mounting frame, and a pressure plate is fixedly connected to the telescopic rod of the vertical cylinder. Paper sheets for environmentally friendly paper bags can be placed on the operating table. The vertical cylinder drives the coating head to descend, and the transverse component drives the coating head horizontally to apply glue to the paper. When the coating head descends, the paper positioning component applies pressure to the paper, preventing displacement and deformation of the paper and avoiding interference with the horizontal displacement of the coating head. This maintains the stability and flatness of the paper, improving the coating quality.
