AI Technical Summary

Technical Problem

Existing label-free PET bottles can only perform laser marking with a small amount of content on the bottle body, and cannot achieve the demand for single bottle sales and large-format and high-capacity production.

Method used

An automatic production equipment for label-free packaging bottles is designed, and multiple laser heads are distributed in fan rings. Multiple angle marking of bottles is achieved through active ring discs and rotating motors, and efficient bottle conveying and marking is achieved through conveying lines and inlet and outlet dials.

Benefits of technology

It realizes large-format and high-capacity marking operations of label-free packaging bottles, supports mass production, simplifies the recycling process, and reduces the utilization of plastics in the production process.
