AI Technical Summary

Technical Problem

In existing food packaging bag folding and forming devices, the fixed spacing design of the upper and lower conveyor rollers cannot adjust the squeezing force according to the thickness and material characteristics of the roll film, which makes the film easy to slip and deviate during conveying, and thick film easy to stretch and deform during conveying, affecting the folding and forming accuracy.

Method used

It adopts an adjustable upper and lower conveyor roller structure, and the distance between the rollers can be adjusted by motor drive, sprocket and chain drive and gear meshing. Combined with tensioning and cleaning components, it ensures stable delivery and cleanliness of the film roll material.

Benefits of technology

It enables precise adjustment based on the thickness and material of the roll film, improving conveying stability and forming accuracy, reducing insufficient friction and stretching deformation during conveying, and ensuring the quality of the packaging bags.
