Description

Technical Field

[0001] This utility model relates to the field of film packaging machine technology, and more specifically, to a servo transmission device for a transparent three-dimensional film packaging machine. Background Art

[0002] Heat shrink film packaging machines use shrink film to wrap around products or packages. After heating, the shrink film shrinks and tightly wraps the product or package, fully displaying the appearance of the item, improving its marketability, and increasing its aesthetic appeal and perceived value. Items packaged by a heat shrink machine are sealed, moisture-proof, and pollution-proof, and protect the goods from external impacts, providing a certain degree of cushioning. Especially when packaging fragile items, it can prevent the contents from scattering when the container breaks. In addition, it can reduce the possibility of products being opened or stolen.

[0003] Currently, the heat sealing section of film packaging machines typically involves symmetrically sliding heat sealing plates connected to the device. When the item to be packaged enters the heat sealing area, the drive mechanism drives the heat sealing plate to heat seal the packaging film. The drive mechanism usually uses a servo cylinder, but this drive method has a limited range of movement for the heat sealing plate, resulting in a small application range and poor applicability. This utility model proposes a new solution to address the above problems. Summary of the Invention
