Description

Technical Field

[0001] The present application relates to the technical field of packaging box packaging, and in particular to a packaging box laminating device. Background Art

[0002] Packaging boxes are widely used. In order to meet application requirements, many packaging boxes need to be covered with a flexible outer film on the outside of the packaging boxes to protect the surface of the packaging boxes from scratches and have a dust-proof effect. The packaging box coating device first covers the outer surface of the packaging box with a heat shrink film, and then heats it so that the film shrinks due to the heat and completely fits the outer surface of the packaging box.

[0003] In the process of laminating and heat shrinking the packaging box, since the product is transported along the conveyor belt to the inside of the heat shrink box for heating and shrinking, the heat shrink film on the lower surface of the packaging box is pressed between the packaging box and the conveyor belt. It may not be completely heat-shrunk and adhere to the lower surface of the packaging box due to poor heating effect. Therefore, improvements are now made to a packaging box laminating equipment.
