Description

Technical Field

[0001] The utility model relates to the technical field of carton production and processing, and particularly relates to a film laminating machine for carton processing. Background Art

[0002] Cartons are common packaging materials in our daily life and are widely used in the transportation, storage, and sales of goods. They are usually made of cardboard or hardboard, and have the characteristics of being lightweight, strong, low-cost, recyclable, etc. The main materials of cartons are cardboard or hardboard, and these materials are usually made from recycled waste paper, meeting the environmental protection requirements. According to the use and load-bearing requirements of cartons, the thickness and strength of the cardboard will vary. Common types of cardboard include single corrugated cardboard, double corrugated cardboard, three-layer cardboard, etc. To protect the printed patterns on the cartons, a film laminating machine is required during the production and processing of cartons.

[0003] Common film laminating machines for carton processing usually consist of structures such as a machine body, a glue spraying system, a film feeding mechanism, a heating system, a film pressing mechanism, and a transmission system. Place the carton in the designated position, start the film laminating machine, the heating system heats the hot melt adhesive to a plastic state, the glue spraying system evenly sprays the hot melt adhesive on the surface of the carton or the film, the film feeding mechanism transports the film to the film laminating position, and the film pressing mechanism firmly presses the film coated with the adhesive on the surface of the carton.

[0004] For traditional film laminating machines for carton processing, when the film drum is in long-term use, in the case of wear or exhaustion of the film material, the film drum needs to be replaced. The film drum is often fixedly installed, which means that multiple components need to be disassembled when replacing the film drum, increasing the complexity of the operation. To solve the above problems, for some film laminating machines for carton processing, fixing blocks are added at both ends of the film drum, and the fixing blocks are rotatably connected to the film drum. At the same time, the fixing blocks fix the film drum at the corresponding position of the film laminating machine through bolts, and the bolts can be rotated to disassemble and assemble the film drum, so as to achieve the purpose of facilitating the disassembly and assembly operation. However, in this way, since the film laminating machine needs to be stopped before replacing the film drum, and the stopping time of the film laminating machine is uncertain and needs to be judged according to the replacement situation of the film drum, it will not only reduce the overall production efficiency, but also break the continuity of production and processing, affecting the smooth progress of the subsequent processes of the box body. Therefore, a film laminating machine for carton processing is proposed. Content of the Utility Model
