AI Technical Summary

Technical Problem

Existing loose-type dryers have problems such as partial adhesion in the middle of the fabric, edge shrinkage, and width instability in the fabric feeding section under high humidity and heat conditions. This results in poor fabric flatness and width consistency, affecting the stability of continuous production and the finished product qualification rate.

Method used

Within the same guide fabric action area, a local pressure relief and anti-sticking structure and an active expansion structure are integrated. The biomimetic micro-valve anti-sticking guide fabric roller assembly and state sensing unit are used for adaptive adjustment to achieve central anti-sticking guide fabric and expansion of both sides. Air pressure is adjusted in combination with the combined state of interface adhesion risk and expansion instability risk.

Benefits of technology

It effectively avoids the superposition of problems of central adhesion obstruction and edge retraction, improves the stability and width consistency of the guide cloth, reduces air consumption, and enhances the adaptability of the device to different types of cloth and working conditions.
