AI Technical Summary

Technical Problem

When processing cartons with small cross-sectional areas and high heights, existing vertical carton erectors suffer from high resistance on the top cover plate and its low position relative to the clamping conveyor belt. This results in uneven resistance between the upper and lower parts of the carton, making it prone to tipping over and affecting the forming quality and tape adhesion.

Method used

The top cover pressure plate structure adopts a combination of buffer springs and thin-walled stainless steel tubes. The conveyor belt is driven by a geared motor. The buffer springs provide elastic support and the rolling friction of the thin-walled stainless steel tubes balances the resistance of the upper and lower parts of the carton, preventing it from tipping over.

Benefits of technology

This achieves a balance of resistance between the upper and lower parts of the carton, improves the flatness of the tape application and the working efficiency of the equipment, prevents the carton from tipping over, and ensures stable transportation.
