[0001] The utility model relates to the technical field of packaging machines, and more specifically to a cam top box device of a transparent three-dimensional film packaging machine. Background Art

[0002] The heat shrink film packaging machine wraps the product or package with shrink film. After heating, the shrink film shrinks and wraps the product or package tightly, fully displaying the appearance of the item, improving the product's marketability, and increasing its aesthetics and value. Items packaged in the heat shrink machine are sealed, moisture-proof, and anti-contamination, and protect the goods from external impacts. It has a certain cushioning effect, especially when packaging fragile items, which can prevent the container from scattering when broken. In addition, it can reduce the possibility of product disassembly and theft.

[0003] The top box device for lifting the packaging box in the currently used heat shrink film packaging machine generally uses a servo cylinder or a swing servo cylinder as a power source to lift the top plate and make reciprocating motion to lift the packaging box. However, there is a lack of a buffer component between the power source and the top plate. During use, the impact of the reciprocating motion will make the equipment run unsteadily, and the swing height is difficult to adjust, which limits its use. The utility model proposes a new solution to the above problems. Summary of the Invention
