AI Technical Summary

Technical Problem

The existing flat rope handle self-sealing paper bag forming device is prone to positional displacement during the paper bag conveying process, which leads to misalignment or bag deformation during hot pressing, affecting the finished product qualification rate and production efficiency.

Method used

Using guide and positioning components, the paper bag is kept centered by a sliding plate and push plate driven by an electric telescopic rod. Combined with a replaceable hot press roller structure, the hot press roller can be quickly replaced using clamping posts and trapezoidal posts, ensuring that the paper bag is in a stable position during the conveying process and can adapt to different hot pressing processes.

Benefits of technology

It improved the forming accuracy of paper bags and the production stability of the equipment, enhanced the versatility and production efficiency of the equipment, solved the problem of hot pressing misalignment and deformation caused by paper bag offset, and improved the finished product qualification rate.
