Description

Technical Field

[0001] This utility model relates to the field of packaging box processing technology, and in particular to a packaging box edge cutting device. Background Technology

[0002] Packaging boxes are containers used to hold and protect products. They can be categorized by material (paper boxes, tin boxes, wooden boxes, acrylic boxes, etc.) and by purpose (gift boxes, food boxes, tea boxes, etc.). They not only protect products during transport through their physical structure but also enhance product quality and brand value through exquisite design.

[0003] In the processing of paper packaging boxes, it is usually necessary to trim the paperboard raw materials according to the production requirements of the packaging boxes. However, the existing trimming equipment is difficult to automatically adjust the trimming position of the paperboard raw materials. When different edges of the paperboard need to be trimmed, the staff usually need to manually adjust the fixed position of the paperboard multiple times, which greatly reduces the trimming efficiency of the paperboard.
