Description

Technical Field

[0001] The utility model relates to the technical field of dust removal devices, in particular to a dust removal and air drying device for coated roll paper before coating. Background Art

[0002] Lamination, also known as "laminization", "mounting", "filming", etc., refers to the use of transparent plastic film to laminate the surface of printed matter through heat pressing to protect and increase the gloss.

[0003] The factory usually coats the rolls of paper continuously and in large quantities, so a large number of rolls of paper are usually stored in the warehouse. Then, the rolls of paper that have been stored for a long time will inevitably adhere to a lot of dust on their surface. The presence of dust will affect the coverage of the film to a certain extent, affecting the adsorption strength of the product film and the quality of the product. Therefore, it is usually necessary to remove dust from the rolls of paper. Common methods include manual dust removal and machine dust removal. For large-scale rolls of paper, the labor intensity of manual dust removal is too high, so machines are usually used for wind dust removal. The dust on the surface of the rolls of paper is removed by high-speed airflow. However, for some dust that is firmly adhered or contains a certain amount of moisture, it is difficult to remove the dust by wind. Therefore, a more efficient dust removal device needs to be designed. Utility Model Content
