AI Technical Summary

Technical Problem

Existing antistatic printing rollers suffer from severe static interference when the environment changes, affecting printing quality and efficiency. Furthermore, the installation of the protective layer is complex, impacting production costs and equipment lifespan.

Method used

The system combines a conductive roller and an ion fan. Static electricity is conducted through the through holes and functional plates on the conductive roller. The graphene coating enhances the antistatic ability, and the ion fan neutralizes the static electricity, ensuring the synchronous and stable rotation of the printing roller and the conductive roller.

Benefits of technology

It effectively eliminates static electricity, improves printing quality and efficiency, extends the service life of printing rollers, simplifies operation processes, and reduces production costs.
