AI Technical Summary

Technical Problem

During the cutting process of the existing corrugated cardboard cutting device, there is sliding friction between the cardboard and the conveyor belt, resulting in a decrease in the quality of the cardboard surface, and the parts of the lifting mechanism are prone to wear and short service life.

Method used

An automatic cutting device for corrugated cardboard is designed. By setting a rolling element at the contact point between the cardboard and the conveyor belt, rolling friction between the cardboard and the rolling element is realized to avoid sliding friction. At the same time, the structure of the hoisting mechanism is optimized to reduce part wear.

Benefits of technology

It effectively avoids sliding friction between cardboard and conveyor belt, improves the surface quality of the cut cardboard, reduces the output of unqualified products, and extends the service life of the conveyor belt, and improves production efficiency.

Abstract

The invention discloses an automatic cutting device for corrugated boards. The automatic cutting device comprises a workbench, a conveying mechanism, a cutting mechanism, a limiting mechanism, a jacking mechanism and a control system. The conveying mechanism comprises a belt conveyor consisting of a group of conveying belts, a driving shaft, a driven shaft and a driving motor; the cutting mechanism comprises a driving element A and a cutting knife; the limiting mechanism comprises a baffle; the jacking mechanism comprises a driving element B and a jacking bracket; the jacking support comprises a connecting frame and a supporting strip. Rolling elements are arranged on the supporting strips, and the upper ends of the rolling elements are higher than the upper surfaces of the supporting strips. According to the automatic cutting device for the corrugated boards, specific design is adopted, sliding friction between the paperboards and the conveying belt can be avoided when the paperboards are cut, the output of unqualified products is reduced, the surface quality of the cut paperboards is guaranteed, the service life of the conveying belt is long, and then the production benefits of enterprises are improved. In addition, the invention correspondingly provides a corrugated board automatic cutting method.
