[0001] This utility model relates to the field of cardboard box production technology, specifically to a laminating device for cardboard box production. Background Technology

[0002] Cardboard boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc., and they come in various specifications and models. In the production process of cardboard boxes, a laminating device is often used to laminate the cardboard to prevent the cardboard boxes from getting damp and being damaged.

[0003] According to the patent application published on the Internet (authorization announcement number: CN 217649019U), "This utility model relates to a laminating device for carton processing, including a laminating machine. The laminating machine includes a support frame, a conveyor rod rotatably mounted on the support frame, a conveyor belt mounted on the conveyor rod, a drive motor mounted on one side of the support frame, a guide device mounted on the support frame, a support platform fixed on the support frame, a film rolling roller rotatably mounted on the support platform, a tensioning roller rotatably mounted on one side of the film rolling roller, a guide roller at the bottom of the tensioning roller, a flattening roller mounted on one side of the guide roller, a flattening groove mounted on the support frame, a flattening rod mounted in the flattening groove, a flattening block mounted on the flattening rod, and a flattening spring mounted on the flattening rod. By setting the tensioning roller and the guide roller, the carton film is tensioned and guided. By setting the flattening rod, flattening block, flattening spring, and flattening roller, the laminating quality is improved. By setting the cutting frame, cutting cylinder, and cutting knife, it is convenient to neatly cut the film on the carton, improving the laminating efficiency and finished product effect."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] During use, this utility model improves the lamination quality by ensuring the carton film adheres tightly to the carton through the use of a flattening groove, flattening rod, flattening block, flattening spring, and flattening roller.
