Technical Field

[0001] The utility model relates to a filtering device for UV curing paint, and belongs to the technical field of UV curing paint processing. Background Art

[0002] UV curing coating is an environmentally friendly coating that cures quickly through ultraviolet (UV) irradiation. It has the advantages of fast curing, high hardness, high gloss, wear resistance, chemical corrosion resistance, etc. Since it does not contain volatile organic compounds (VOC) and is environmentally friendly, it is widely used in surface coating and protection in the fields of electronic products, wood products, plastics, paper, etc.

[0003] During the processing of UV-curing paint, a filtering device is needed to filter it. However, since the feed port of the filtering equipment corresponds to a part of the filter, when a large amount of UV-curing paint that needs to be filtered passes through the feed port and enters the filter surface for filtration, the UV-curing paint will be concentrated and fall to the same part of the filter. Long-term use may cause the filter to become blocked, and at the same time, the functionality of the filter will not be fully utilized.

[0004] Therefore, a filtering device for UV curing coating is proposed. Utility Model Content
