Description

Technical Field

[0001] This utility model relates to the field of paper box processing technology, and in particular to a folding mechanism for a paper box gluing machine. Background Technology

[0002] A cardboard box is a paper container used to package goods. It is usually made of cardboard or other paper materials and comes in a variety of shapes and designs. It is suitable for a wide range of goods, including food, medicine, and electronic products. During the production and processing of cardboard boxes, they need to be folded using folding equipment.

[0003] For example, Chinese patent document CN220973477U describes a paper box bottom folding mechanism, including a support device. A folding frame is fixedly connected to the middle section side wall of the support device. An extrusion device is installed on the support device above the folding frame, and an extrusion block is fixedly connected to the output end of the extrusion device. Through the coordinated arrangement of structures such as a glue cylinder, piston, electric push rod, glue nozzle, and contact switch, when the user folds the paperboard by pressing it into the folding frame using the extrusion block, the paperboard triggers the contact switch, energizing the electric push rod and pushing the piston upward. This causes the glue in the glue cylinder cavity to be evenly applied through the glue nozzle to the joint of the paperboard used to form the side wall of the paper box, thus bonding the paperboard. This avoids the problem of some folding devices failing to bond the joint of the folded parts after folding the paper box, requiring the user to re-bond and fix it after folding, which greatly reduces the efficiency of paper box production.

[0004] However, the folding mechanism described above can only fold boxes of a fixed size during use, and is not convenient for folding boxes of other sizes, which has certain limitations. Summary of the Invention
