uv curing machine and its uv light box

Abstract

The embodiment of the present invention relates to a UV curing machine and its UV light box. The UV light box includes a reflector with an arc shape and an inner arc as a reflective surface, a UV lamp arranged on one side of the reflective surface of the reflector, and a UV lamp arranged on the The fan on one side of the outer arc of the reflector and the wind guide plate located between the reflector and the UV lamp near the arc top of the reflector and extending along the length direction of the reflector. The plate faces the through hole and has a width greater than the size of the through hole in the width direction of the air guide plate. In the embodiment of the present invention, the high-speed airflow blown by the fan blows on the arc top of the outer arc surface of the reflector and flows along the two sides of the outer arc surface. Part of the airflow also passes through the through hole and blows on the air guide plate, and then blows to The reflective surface of the reflector flows along the reflective surface, blowing and cooling both inside and outside the reflector, which is conducive to improving the reflectivity of UV energy, and the airflow flowing along the reflective surface is finally blown on the product to be cured for air cooling and heat dissipation, which is beneficial Improve curing effect.

Description

technical field [0001] The embodiment of the present invention relates to the field of UV curing technology, in particular to a UV curing machine and its UV light box. Background technique [0002] The UV curing machine uses a UV light box (for example: LED-UV lamp) to cure UV ink, UV glue, UV coating, etc., and is widely used in many fields such as communications, electronics, optics, and printing. The UV lamp and other components inside the UV light box generate a lot of heat when they work, and the higher the temperature of the reflector, the lower its UV energy reflection ability. In actual production, it is necessary to dissipate heat from the UV lamp in time. [0003] A kind of existing UV curing machine, the UV lamp box that it adopts comprises UV lamp, and described UV lamp one side is provided with reflective plate, and reflective plate is used for also reflecting the UV energy that UV lamp emits toward the direction away from the product to be cured to the product ...

AI Technical Summary

Problems solved by technology

With this heat dissipation structure, only the side surface of the reflector away from the UV lamp is blown by the wind, and the heat dissipation effect of the reflector itself is not ideal, and the UV lamp and the product to be cured are blocked by the reflector and cannot be blown by the wind. The heat of the UV lamp is also easy to accumulate and cause the temperature of the UV lamp to be too high, which will affect the service life of the UV lamp, and the high temperature of the product to be cured will also affect the curing effect
