[0002] Cardboard boxes can be seen everywhere in our lives. When transporting items, the boxes can not only load the items, but also protect the items very well. However, the cardboard boxes in the prior art have poor moisture resistance. In humid or rainy environments, the cardboard boxes are easy to soften, and moisture will enter the interior of the cardboard boxes and cause damage to the transported items. At this time, covering the cardboard boxes with a moisture-proof film can alleviate the moisture problem of the cardboard boxes.

[0003] The existing laminating technology often adopts a cardboard laminating device for moisture-proof cartons disclosed in announcement number CN219523046U, which conveys the cardboard through a roller, cleans the cardboard using an electrostatic roller and a dust suction mechanism, and then laminates the cardboard through a laminating roller. Subsequently, a cutting mechanism is used to cut the laminated cardboard. However, when the back side needs to be laminated, the cardboard needs to be put back into the device for the laminating process, which not only requires more manpower, but also easily causes the lamination misalignment of the two sides, and seriously affects the laminating operation efficiency.
