Description

Technical Field

[0001] The utility model relates to the technical field of packaging box laminating, in particular to an anti-wrinkle packaging box laminating device based on dynamic tension control. Background Art

[0002] The packaging box lamination is to heat the packaging film through a laminating device so that the packaging film on the packaging box shrinks and is wrapped on the outer surface of the required packaging box, which can make the packaging box look more atmospheric and upscale. At the same time, after the packaging box is laminarized, its surface will not be contaminated by dust or other impurities during transportation, which plays a role in protecting the packaging box.

[0003] When the laminating roller of the existing device runs at high speed for a long time, the heat and humidity generated by friction can easily cause the laminating roller to wear and crack. The wear causes the local diameter of the laminating roller to become smaller. When the same power is applied, there is a deviation in the pressure transmitted to the film by different parts of the roller, resulting in uneven force on the film and wrinkles during lamination.
