Description

Technical Field

[0001] The utility model relates to the technical field of laminators for printing paper, in particular to a cooling device for a laminator. Background Art

[0002] The plastic sealing process is to use a polyester film coated with hot melt adhesive to bond the sealed items inside the plastic film through a laminating machine. Since the process is carried out under a certain pressure and high temperature, and uses high-quality polyester film and hot melt adhesive with good transparency, it can not only ensure that the plastic-sealed items are not damaged at room temperature, but also increase the visual effect of the items. In this process, the technical performance of the laminating machine is an important factor in ensuring the quality of plastic sealing.

[0003] At present, the existing laminator cannot quickly cool the surface of the product after laminating the printed paper. As a result, the surface temperature of the product will be high, and the surface laminating film will easily deform during movement or bending, affecting the quality of the product laminating. In addition, the conveying pressure roller in the laminator cannot be adjusted according to the thickness of the paper. Therefore, a cooling device for the laminator is proposed to solve the above problems. Utility Model Content
