Description

Technical Field

[0001] The utility model relates to the technical field of drying equipment, in particular to a digital UV drying system. Background Technique

[0002] The main function of the digital UV drying system is to use ultraviolet radiation for rapid drying and curing. The digital UV drying system is widely used in many fields such as electronics, optical fibers, liquid crystal displays, printing, packaging, etc., such as for the drying and curing of printed products, the UV light-curing glue dispensing and curing of electronic parts, the drying and curing of UV oil and glue on the surfaces of plastic buttons, metal plates, etc.

[0003] During the use of the digital UV drying system, it is usually the conveying equipment that drives the materials to be dried to move. When the materials to be dried move to the lower side of the ultraviolet irradiation lamp, through the regulation of the control equipment, the ultraviolet irradiation lamp starts to operate, and the ultraviolet irradiation lamp emits high-intensity ultraviolet rays, which react chemically with the UV ink on the surface of the materials, so that the UV ink is quickly cured, thereby achieving the effect of curing and drying.

[0004] In the process of working of the existing digital UV drying system, since the positions of the ultraviolet irradiation lamps are fixed, when there are irregular shapes such as depressions or protrusions on the surface of an object during the use of the ultraviolet irradiation lamp, there will be some irradiation dead angles. The fixed ultraviolet lamps are difficult to completely irradiate these areas. Some areas will be over-irradiated, while other areas may be under-irradiated. Finally, there will be a problem that the drying quality is reduced due to incomplete local drying of the UV ink. For this reason, we propose a digital UV drying system. Content of the Utility Model
