Description

Technical Field

[0001] The utility model relates to the technical field of laminating machines, in particular to an automatic laminating machine for packaging gift boxes. Background Art

[0002] In order to improve the appearance and sealing of gift boxes, it is usually necessary to coat the gift boxes with film, so various coating devices are proposed in the prior art. For example, the Chinese utility model patent with announcement number CN215945087U proposes a wine box hot-pressing laminating machine, which limits and guides the wine box through a guide plate, so that the wine box will not be placed incorrectly when the plastic packaging is cut and sealed, thereby avoiding the occurrence of holes after the wine box is coated, affecting the sealing of the overall packaging; at the same time, the distance between the two guide plates is adjustable, which makes the laminating machine suitable for wine boxes of different sizes.

[0003] Usually, the conveyor belt of a laminating machine is generally divided into a loading conveyor belt, a film wrapping conveyor belt and a thermoplastic conveyor belt. However, the above-mentioned prior art only transports the gift box backwards by the friction of the traditional conveyor belt, and does not have a structure and function to further push the gift box on the loading conveyor belt. The resistance of the film will push the gift box toward the loading conveyor belt, resulting in the gift box not being smoothly transported from the loading conveyor belt to the film wrapping conveyor belt, and the gift box is not stable enough when wrapped with the film.
