AI Technical Summary

Technical Problem

In existing technologies, the sizing process of HEPA filter paper relies on manual application, which leads to uneven sizing, glue loss, and reduced filtration area after curing. Furthermore, it is difficult to maintain the stability of the "V"-shaped structure of the filter paper, affecting product quality control.

Method used

A high-efficiency filter paper gluing device was designed. By setting support blocks and figure-eight plates on the conveyor line to limit the filter paper, and combining the gluing components and the gluing roller, the device can automatically and evenly apply glue and cure it during the conveying process. This ensures that the glue is mainly applied to the creases and avoids leakage and loss.

Benefits of technology

This achieves uniform distribution of the adhesive, avoids uneven application and loss, improves product quality control, and ensures the stable shape and filtration efficiency of the filter paper.

Abstract

The application discloses the technical fields of filter paper sizing processing technology, and aims to solve the problems of uneven usage and lateral overflow caused by manual sizing at the crease position of filter paper in the prior art. The application comprises a paper folding machine, a conveying line is arranged at the paper outlet end of the paper folding machine, the conveying line is composed of a plurality of belt conveying components, a plurality of supporting blocks are arranged below the conveying line, a mounting rack is arranged directly above the supporting blocks, eight-shaped plates are mounted on the mounting rack, each eight-shaped plate can be pressed on the corresponding supporting block by extruding the filter paper, the eight-shaped plate can reserve the tip part of the filter paper after pressing the filter paper, and a sizing assembly is further arranged on the mounting rack. The application is used for automatically realizing the pre-sizing process at the crease position of the filter paper, can efficiently and stably and uniformly apply glue to the crease position of the folded filter paper, is favorable for avoiding glue loss and lateral overflow from affecting the filtering surface, and thus improves the product quality control capability.
