Description

A longitudinal cutting machine with deviation correction function

Technical Field

The utility model relates to the technical field of longitudinal cutting machines, in particular to a longitudinal cutting machine with a deviation correction function.

Background Art

In the production of corrugated cardboard, a slitting machine is usually used to cut the corrugated cardboard. The slitting machine is a material processing equipment that uses a tool material to cut longitudinally to obtain the required size. It is often used for cutting corrugated cardboard, fabrics and metal foils.

During the production process, the staff places the corrugated cardboard on the conveying device of the longitudinal cutting machine. The conveying device transports the corrugated cardboard to the circular cutting knife for cutting and trimming, and divides the corrugated cardboard into strips.

However, when the longitudinal cutting machine feeds paper, it cannot ensure that the corrugated cardboard is always in the center position, which causes the relative position of the corrugated cardboard and the circular cutter to deviate, resulting in skewed cutting of the corrugated cardboard in the subsequent slitting process, affecting the accuracy of subsequent corrugated cardboard slitting.

In view of this, we propose a longitudinal cutting machine with a deviation correction function.
