Description

Technical Field

[0001] The utility model relates to the technical field related to paper box processing, in particular to a paper box laminating, dehumidifying and air-drying device. Background Art

[0002] There are multiple processing steps in the process of paper box processing, and surface coating is one of them. Paper box coating dehumidification and air drying equipment usually adopts the cooperation of drying chamber and fan to dry the film attached to the paper box. At the same time, the fan in the drying chamber can dehumidify the film on the paper box and air dry it at the same time, thereby improving the air drying efficiency and quality strength of the paper box.

[0003] A dust removal and dehumidification device for a safe laminating machine disclosed in the publication number CN211467854U is connected to an external power supply when in use, the substrate moves to the left along the base, the film to be coated is attached to the film pressing assembly, and when the substrate passes under the frame, the airflow is introduced into the heating chamber by the fan, and the airflow is heated and heated by the electric heating wire, and the generated hot air is sent downward along the air outlet on the exhaust plate, so as to dry and dehumidify the surface of the substrate, and the screw motor drives the screw to rotate, so that the nut seat is raised and lowered along the guide groove, and the height of the mounting seat at the lower end of the dust removal bracket can be adjusted, so that the anti-static dust sticking rubber roller is attached to the surface of the substrate, thereby performing adhesion and dust removal:

[0004] However, the above scheme still has the following problems when in use: when in use, the paper box is moved to the bottom of the fan through the conveying mechanism for air drying. When the paper box and the film are dried and air dried, since the drying chamber and the fan work simultaneously, the ink on the paper box has not been completely processed by the drying chamber. When the fan is running at the same time, it will cause the position of the film to shift and cause bubbles and wrinkles, etc., so when this happens, it is necessary to stop the machine for correction.

[0005] Therefore, we propose a dehumidification and air-drying device for carton lamination to solve the above problems. Utility Model Content
