Background

The UV lamp is a gas discharge lamp, in which a certain amount of high-purity mercury is added to a vacuum quartz tube, and a voltage difference (voltage drop) is applied to electrodes at both ends to generate ion discharge, thereby generating ultraviolet radiation, which is called an ultraviolet lamp tube for short.

The existing UV paint curing device generally adopts high-pressure mercury lamps, crop lamps and other curing woodwork surface coating UV paint, and can quickly cure the UV paint of a coating layer. In order to achieve a good curing effect, it is an essential step to adjust the height of the lamp tube due to different thicknesses and materials of the plate.

Among them, the following disadvantages are present: 1, if the power supply is turned off, the lamp is extinguished, the production progress is influenced, and the whole production line stops production, 2, if the power supply is not turned off, the height of the lampshade is adjusted, and the direct light or the reflected light of the UV lamp can inevitably irradiate the skin or eyes; 3. the traditional lampshade adjusting mode has large adjusting amplitude between each section, and the optimal height is difficult to ensure, so that the optimal curing effect is difficult to realize. In addition, if the ultraviolet light directly irradiates the skin, the epidermis is necrotized, and even the hair follicle of the belt is damaged; in addition, if the eyes are used for direct vision, the eyes can feel dazzling, burning pain can be generated, and the human body is easy to be damaged.
