UV curing device with large irradiation range

Abstract

The invention relates to the technical field of UV curing equipment, and particularly relates to a UV curing device with a large irradiation range. The UV curing device comprises a main rack, UV curing lamps, a centrifugal fan and a driving motor. According to the UV curing device with the large irradiation range, the inverted V-shaped structural design is adopted in the UV irradiation section, through the direct irradiation and reflection phase structure, the irradiation stroke is greatly increased under the condition that the number of the UV curing lamps is not changed, and the curing effect is improved; heat generated by the irradiation section can be rapidly pumped away, and the stability and durability of the equipment are improved; the irradiation range of the UV curing device is adjustable, and the application range is wider; and an elastic lateral tensioning roller is installed between a guide roller laterally arranged on the inner side face of the main rack and an inner supporting roller, the attaching performance and tensioning degree of a belt conveying mechanism and the surface of a middle guide support can be improved, and the conveying stability is guaranteed.

Description

technical field [0001] The invention relates to the technical field of UV fixed telephone equipment, in particular to a UV curing device with a large irradiation range. Background technique [0002] UV curing is ultraviolet curing. UV is the English abbreviation of ultraviolet light. Curing refers to the process of changing a substance from a low molecular weight to a high molecular weight. UV curing generally refers to the curing conditions or requirements of coatings, inks, adhesives or other potting sealants that need to be cured by ultraviolet light, which is different from heating curing, adhesive curing, natural curing, etc. [0003] The UV curing device is a device that uses a UV light source to cure UV coatings. It reacts chemically with the photosensitizer in the UV coatings to dry and cure instantly. [0004] The UV curing device on the market mainly completes the curing through direct vertical irradiation of UV lamp tubes. The irradiation area is limited by the d...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is: in order to solve the problems in the above-mentioned background technology, an improved UV curing device with a large irradiation range is provided to solve the problem that the irradiation area of ​​UV curing devices on the market is affected by the diameter and number of UV lamp tubes. The limitation is relatively large, resulting in a very limited irradiation range, and the irradiation stroke cannot be controlled and adjusted, and long-term irradiation will cause heat accumulation due to the relatively high optical power density, which will affect the service life of the equipment and the problem of curing stability.
