[0002] In the paper box production process, a grooving knife structure is required to groove the paper boxes. Existing grooving knives are fixedly installed on the production line to groove the paper boxes on the line. This method limits the grooving knife to a fixed position and prevents flexible, localized grooving of the paper boxes, causing inconvenience in paper box production. To solve the above problems, this utility model provides a paper box localized grooving knife structure. Utility Model Content

[0003] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a partial grooving knife structure for cardboard boxes. This structure uses a cylinder mounted on a support rod to drive an L-shaped top plate to move back and forth, thereby driving the knife head assembly to extend and retract, enabling partial grooving at different locations on the cardboard box. This is flexible, convenient, and practical. Furthermore, the use of a cylinder fixed to the support rod results in a compact size, facilitating localized installation. This solves the technical problems mentioned in the background section.
