Description

Technical Field

[0002] UV curing is ultraviolet curing. UV is the abbreviation of ultraviolet rays. Curing refers to the process of converting a substance from a low molecular weight to a high molecular weight. UV curing generally refers to the curing conditions or requirements of coatings (paints), inks, adhesives (glue) or other potting sealants that need to be cured by ultraviolet rays. It is different from heating curing, crosslinking agent (curing agent) curing, natural curing, etc. UV printing is a printing process that dries and cures inks through ultraviolet light. It is necessary to match inks containing photosensitizers with curing lamps. The application of UV printing is one of the most important contents in the printing industry.

[0003] At present, the surface of the ultraviolet curing lamp used in UV printing is easily contaminated during operation. If it is not cleaned in time, the curing effect will be reduced. At the same time, the ultraviolet curing lamp will emit a large amount of heat during operation. Coupled with long-term operation, the service life will be shortened. Therefore, a UV curing device in a UV printer is needed. Utility Model Content
