UV oil paint solidification device for spraying industry

Abstract

The invention discloses a UV oil paint solidification device for the spraying industry. The UV oil paint solidification device for the spraying industry comprises a rack, the rack is provided with a support plate, the support plate is provided with a UV oil paint solidification box, and a transmission device is arranged between the support plate and the UV oil paint solidification box; an LED UV oil paint solidification light source is arranged in the UV oil paint solidification box; the LED UV oil paint solidification light source comprises a power circuit board, and an LED UV light emitting module and / or LED UV ultraviolet light emitting lamp beads are installed on the power circuit board; the LED UV light emitting module and the LED UV ultraviolet light emitting lamp beads are all composed of a plurality of ultraviolet light emitting semiconductors; the ultraviolet light emitting semiconductors are LED ultraviolet light emitting devices, and the wavelength coverage of the light emitted ranges from 200 nm to 500 nm. The UV oil paint solidification device for the spraying industry does not produce mercury and harmful gases; the voltage needed is low, and the occurrence of the safety production problem is avoided; no preheating is needed in use, the service life is long and can be as long as 25000-30000 hours; the production cost is reduced due to the fact that no high temperature is needed and no preheating and no additional installation of fast valves are needed.

Description

technical field [0001] The invention relates to a UV paint curing device used in the spraying industry. Background technique [0002] At present, in the spraying industry such as furniture, there has been a trend of using UV paint for spraying. Another explanation of UV paint is ultraviolet curing coating (ultraviolet curing coating), referred to as UV paint, which is a coating that can be quickly cured into a film within a few seconds under the irradiation of ultraviolet rays (ultraviolet, referred to as UV). [0003] The main features of UV paint are: after strong ultraviolet light curing treatment, the color is stable and long-lasting, which can effectively solve the problem of fading and color difference of the paint surface, and the paint film is full without orange peel; the hardness of the paint surface is twice that of other paints, and it is scratch-resistant , acid and alkali resistance, not easy to deform. [0004] Existing UV paint curing devices all adopt UV m...

Problems solved by technology

Yet this UV mercury lamp that is used for curing paint has the following problems: (1) in the UV mercury lamp, mercury, iron and harmful gases containing heavy metals are more serious to air pollution, to the injury of human body and equipment, Harm the health of operators; (2) Traditional UV mercury lamps are mainly driven by 1500V-2000V high voltage, normally about 20KW each, and only one-tenth of the power converted into useful curing effect for paint, And it must be preheated, and the practical life is only about 1000 hours. After being scrapped, the heavy metal mercury, iron and argon gas added in the lamp tube will cause irreparable damage to the environment; (3) UV mercury lamp needs to remove the mercury in the tube cavity Ultraviolet rays can only be emitted after atomization, and the temperature needs to be above 600°C. Among them, only 15%-25% of ultraviolet rays are used for UV paint curing, and more than 50% of infrared rays. The heat release is large, which is harmful to the product environment, human body, and equipment. Hazards (4) Due to the reason of the production of UV mercury lamp, the two ends of the lamp tube and the middle of the lamp tube emit uneven light, resulting in uneven curing of the UV paint of the product, and in severe cases, the batch of products are scrapped; According to the spectrum required for UV paint curing and the length of the format, the emitted ultraviolet light is adjusted to the spectrum required for UV paint curing, and the length of the curing format required for UV paint cannot be adjusted, resulting in a great waste of energy.
