Description

Technical Field

[0001] The utility model belongs to the technical field of gluing equipment, in particular to a gluing equipment for paper box production. Background Art

[0002] Cardboard boxes are a commonly used packaging method in the circulation of products. They are mainly used to protect products, facilitate storage and transportation, and promote sales. This packaging method is mainly made of paper boxes, which have the characteristics of easy material acquisition, light weight, easy printing, easy design and molding, and low cost. Cardboard boxes are generally square, and according to the different requirements of the quality of the gift boxes, the cardboard boxes include two layers: an inner lining and an outer shell, which is not easy to be damaged. On the existing production line, it is necessary to manually apply glue to the outer side of the inner lining shell, and then glue the outer shell to the outer side of the inner lining shell. However, the efficiency of manual gluing is relatively low, resulting in high production costs. In addition, there is no fixing mechanism during the gluing process. Holding the outer side of the inner lining shell can easily interfere with the glued part, affecting work efficiency. Utility Model Content
