AI Technical Summary

Technical Problem

In the prior art, the edge of the lid film is raised affecting the appearance, and the imperfect pressing leads to overflow of nitrogen inside the tank and the entry of external oxygen, causing tea leaves to oxidize, affecting taste and nutrition.

Method used

An artificial can sealing mechanism is designed, and two sets of membrane pressing devices are used to press the cover film in sequence to ensure that the edge of the cover film is tightly wrapped in the tank opening position, and the cover film is automatically absorbed and placed through the cover film assembly to reduce manual operation.

Benefits of technology

Through tight cover film pressing, ensure that nitrogen is retained in the tank, preventing oxygen from entering, extending the quality duration of tea leaves, and improving the aesthetics of the product and customer satisfaction.
