[0002] A UV varnishing machine is a device used for post-printing processing, primarily for partial or full varnishing of printed surfaces. Using ultraviolet (UV) curing technology, UV varnishing machines rapidly dry varnish, forming a hard, smooth, and glossy protective layer on the surface of printed materials. This not only enhances the visual quality of the product but also protects the printed content and increases its durability. Dust adhering to paper can affect the varnishing effect. Traditional methods primarily use a cleaning brush and a vacuum cleaner to remove dust from the paper surface. Static eliminators are also used to eliminate static electricity on the paper to prevent dust absorption. However, excessive suction from the vacuum cleaner can affect the conveyor's transport of the paper, while insufficient suction fails to remove dust from the paper surface, making it inconvenient to use.

The air inlet groove (10304) is provided inside the air guide shell (10301) to facilitate the air flow after dust removal. The air enters the air flow nozzle (10303) from the air inlet groove (10304), and is ejected from the air blowing slot (10306) under the guidance of the air flow nozzle (10303), forming a narrow and concentrated air flow. This air flow can form a thin air layer on the surface of the paper to help remove dust and light impurities, but will not exert enough force on the paper to blow it up, and will not affect the transmission of the paper by the conveyor belt. The dust cup (10206) has an hourglass-shaped structure with a closing in the middle, and the dust cup (10206) is made of transparent plastic, which is convenient for avoiding the dust cup (10206). The dust collected inside the dust collecting cup (10206) will be stirred up by the air flow, which can effectively improve the dust removal effect of the dust removal component (102), and is convenient for observing the amount of dust collected inside the dust collecting cup (10206) from the outside, so that the dust inside the dust collecting cup (10206) can be processed in time. The installation card block (10205) is fixedly installed on the outside of the bottom end of the cyclone cover (10201), and the installation card slot (10208) is engaged with the installation card block (10205), so that the dust collecting cup (10206) can be easily installed and disassembled, and the dust collected inside can be processed conveniently.
