Description

Technical Field

[0001] This utility model relates to the technical field of adhesive roller mechanism, and in particular to an adhesive roller mechanism with automatic air drying function and a flexographic printing machine. Background Technology

[0002] Flexographic printing presses use flexible printing plates and transfer ink through anilox rollers for printing. It is a type of letterpress printing process, often abbreviated as flexographic printing. During printing, the ink fountain roller carries ink from the ink fountain box and then evenly coats the ink onto the anilox roller. The anilox roller then coats the ink onto the printing plate roller. Under the pressure of the pressure roller, the ink layer on the printing plate roller is transferred to the surface of the substrate, forming clear images and text.

[0003] Currently, flexographic printing machines on the market often suffer from inconsistent print quality due to dust adhering to the printed materials, sometimes even leading to the scrapping of the printed products. Existing technologies primarily rely on dust removal rollers to remove dust from the printed materials, which results in dust accumulation on the rollers, necessitating cleaning. After cleaning, the dust rollers in existing technologies mainly rely on natural air drying, which is time-consuming and cannot meet current usage requirements. Therefore, a dust roller mechanism and flexographic printing machine with an automatic air drying function are provided to solve the above problems. Summary of the Invention
