AI Technical Summary

Technical Problem

It is difficult for existing production equipment to achieve unified hole punching of PET foamed plates on the production line, resulting in low production and forming efficiency of PET foamed plates.

Method used

A drilling device for a PET foamed plate production line is designed, including a conveyor roller, a drilling assembly and a lifting assembly. The lifting assembly realizes adsorption and lifting of the PET foam plate through the lifting body and the driving part, and performs drilling operations in conjunction with the drilling assembly.

Benefits of technology

The production and forming efficiency of the PET foam plate is improved, and it can synchronize with the beat of the production line, and the PET foam plate after drilling is transported to the next station in one direction, and the stability of the PET foam plate when it is drilled is improved.
