AI Technical Summary

Technical Problem

Containers manufactured in existing equipment are not cooled sufficiently, especially before labeling, leading to stress cracks and leaks after filling, which affects inventory quality.

Method used

Using gas or a mixture of gases as the cooling medium, the cooling section extends into the interior of the labeling unit, especially along the labeling turntable and labeling component area, providing more comprehensive cooling, including bottom cooling, to ensure that the container reaches sufficient stability before labeling and filling.

Benefits of technology

This effectively prevents stress cracks from forming in the container during subsequent processing, ensuring the integrity of the container and the safety of the inventory, and improving production efficiency and equipment space utilization.
