[0002] In the current technological background of the packaging industry, the laminating machine, as an indispensable automated equipment, has significantly improved the quality and efficiency of heat shrink film packaging for packaging boxes. The equipment integrates a series of precision mechanical actions, including automatic supply of heat shrink film, precise cutting, smooth transfer, effective unfolding and precise embedding of packaging boxes, thus laying the foundation for the subsequent hot air shrinking process and ensuring that the film layer on the surface of the packaging box fits tightly, which not only beautifies the appearance but also enhances the protection effect.

[0003] However, the existing laminating machine technology in the market has exposed some limitations when facing the demand for diversified packaging box sizes, especially in the design of the packaging box transmission system.

[0004] Specifically, these devices are often limited by fixed transmission mechanism designs. They either completely lack the ability to adapt to different box widths, resulting in the ability to only process packaging boxes within a certain size range. Or, although manual adjustment is allowed to accommodate different box widths, this process is cumbersome and inefficient, and automated adjustment cannot be achieved, which seriously restricts production flexibility and efficiency.

[0005] In view of this, the inventor specially designed a box width adaptive device and a laminating machine with the device, and this case was thus generated. Utility Model Content
