UV curing machine provided with 360-degree rotary light source

Abstract

The invention discloses a UV curing machine provided with a 360-degree rotary light source. The UV curing machine comprises a UV curing machine body, the UV curing machine body is provided with a feed inlet, a discharge port, an exhaust fan and a transmission table, and an electronic control device is further arranged in the machine. The electronic control device is installed above the feed inlet of the UV curing machine body. A UV lamp is rotationally installed in the UV curing machine body through a rotary bearing. The rotary bearing is connected with the electronic device through a wire and is controlled by the electronic control device to rotate. By means of the design, the illumination range and stability of the light source are guaranteed, and product quality is improved.

Description

technical field [0001] The invention relates to a light curing device, in particular to a UV curing machine with a 360-degree rotating light source, belonging to the technical field of curing equipment. Background technique [0002] Realize the UV curing machine with adjustable light source. Among them, UV is the English abbreviation of Ultra-Violet Ray. The industrial UV wavelength is 200nm to 450nm as its application range. Use UV to irradiate "UV irradiation hardenable materials" and The process that makes it harden is called "UVCuringProcess". 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, the material cannot be fully cured no matt...

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 completely cured.

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

At present, due to the high light temperature of the UV lamp, the white ink on the white cover plate is found to turn yellow after the white cover plate is pasted and cured, which seriously affects the quality of the product.
