Light reflection single-box UV curing machine

Abstract

A light reflection single-box UV curing machine comprises a rack. A conveying bin is arranged at the position, close to the top end, of the rack. A feeding opening and a discharging opening are formed in the left side and the right side of the conveying bin. A plurality of conveying shafts are arranged in the conveying bin in the horizontal direction side by side at intervals. The conveying shafts are sleeved with wear-resisting sleeves. UV lamps are arranged between the adjacent conveying shafts. UV boxes are arranged at the positions, right opposite to the upper portions of the UV lamps, of the top end of the conveying bin. Each UV lamp comprises a mounting support, a lampshade arranged on the support in a covering manner, a vertical UV lamp tube arranged in the center of the support and a hemispherical reflector arranged below the UV lamp tube. The height of the UV lamp tubes and the height of the hemispherical reflectors are smaller than the horizontal height of the conveying shafts. The structure of the UV lamps is improved, the incident angles and the arrangement positions of the UV lamps are changed, and therefore the light curing efficiency is greatly improved, and the problems that UV ink (gloss ink) surface layer aging, closing, embrittlement and the like happen, meanwhile, the adhesive force of ink (gloss ink) is poor, and the overprint interlayer binding force is poor are effectively solved.

Description

technical field [0001] The invention relates to the field of UV board production, in particular to a UV board curing machine. Background technique [0002] Realize the UV curing machine with adjustable light source. Among them, UV is the English abbreviation of ultraviolet light. The wavelength of industrial UV is 200nm to 450nm. , called "UVCuring Process". The principle of UV curing is that ultraviolet rays irradiate special glue to make the glue polymerize and then cure. In the capacitive screen bonding process, the product is placed on the conveyor belt of the UV curing machine, and is irradiated by the UV lamp of the UV curing machine to dry the water glue applied on the capacitive screen. If the light temperature of the UV lamp is low, no matter how many times the material passes through the UV curing device, the material will not be fully cured. On the contrary, it will also make the surface layer of UV ink (varnish) age, seal, and become brittle. At the same time,...

AI Technical Summary

Problems solved by technology

If the light temperature of the UV lamp is low, no matter how many times the material passes through the UV curing device, the material will not be fully cured.

On the contrary, it will also make the surface layer of UV ink (varnish) age, seal, become brittle, etc. At the same time, the adhesion of ink (varnish) is not good, which will make the interlayer bonding of overprinting poor

The UV lamps in the existing single-illumination box are irradiated from top to bottom, the irradiation temperature is low, and the light cannot be effectively gathered, which needs to be improved
