AI Technical Summary

Technical Problem

Existing coating equipment is prone to contaminating the tape with impurities during the adhesive recycling process, and it cannot effectively adjust the coating thickness or recycle excess adhesive.

Method used

A pressure-sensitive adhesive coating device for self-adhesive tape was designed. A purification mechanism is set up to filter the recycled adhesive, including components such as a filter plate, rollers, scraper, and lifting plate, to separate impurities and reuse the adhesive. Combined with the power transmission system of the coating roller and reciprocating roller, the device achieves uniform coating of adhesive and recycling of excess adhesive.

Benefits of technology

It effectively prevents impurities from contaminating the tape during the glue recycling process, enabling the reuse of glue, saving resources, improving work efficiency, and reducing energy waste.
