[0002] UV glazing machine is a kind of equipment used for post-printing processing. It is mainly used for partial or full glazing of printed surfaces. By using ultraviolet (UV) curing technology, UV glazing machine can quickly dry glazing oil, thereby forming a hard, smooth and shiny protective layer on the surface of printed matter.

A dust collecting cup (10206) is provided at the bottom of the cyclone cover (10201) to collect dust separated from the air for subsequent treatment. A second interface (10302) is provided at the top of the air guide shell (10301). The second interface (10302) is connected to the other end of the connecting pipe (10106) to facilitate the airflow after dust removal to enter the blowing assembly (103) for blowing. The air inlet groove (10304) is arranged inside the air guide shell (10301) to facilitate the air 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) is an hourglass-shaped structure with a closed end 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 cup (10206) will be stirred up by the airflow, which can effectively improve the dust removal effect of the dust removal component (102), and it is convenient to observe the amount of dust collected inside the dust cup (10206) from the outside, so that the dust inside the dust cup (10206) can be processed in time. A mounting block (10205) is fixedly installed on the outside of the bottom end of the cyclone cover (10201), and the mounting slot (10208) is connected to the mounting block (10205) by snapping, so that the dust cup (10206) can be easily installed and disassembled, so that the dust collected inside can be processed conveniently.
