Problems solved by technology
[0005] Compared with the high-pressure mercury lamp and metal halide lamp UV curing method, the UV light-emitting diode curing method can greatly reduce energy consumption, no ozone and volatile organic substance emissions are generated during the curing process, the light source has a long service life, and no preheating and cooling are required. It is especially beneficial for label printing and printing of heat-sensitive printing materials, but the light source irradiation range and light source irradiation intensity of the existing UV LED curing device are fixed, and the light source cannot be adjusted in time according to the width of the printed matter and the printing speed. The irradiation range and light source irradiation intensity, large energy consumption, low system stability and control accuracy, poor UV curing effect,

The invention provides an ultraviolet combined light source rapid solidification device for a label printing machine. The ultraviolet combined light source rapid solidification device for the label printing machine is composed of a rectangular box, a light source controller, a first rectangular water-cooling radiator, a second rectangular water-cooling radiator, a third rectangular water-cooling radiator, a fourth rectangular water-cooling radiator, a first surface light source, a second surface light source, a third surface light source, a fourth surface light surface, a fifth surface light source, a sixth surface light source, a first big parabolic cylindrical lens, a second big parabolic cylindrical lens, a small parabolic cylindrical lens, a width detection mechanism and a speed sensor. According to the ultraviolet combined light source rapid solidification device for the label printing machine, two sets of intense light sources with the light intensity being doubled are formed by ultraviolet light emitting diodes and the parabolic cylindrical lenses, and printing ink on the surface layer and the deep layer of label paper is solidified at the same time; and in addition, by detecting the label printing width and the label printing speed in real time through the device, the irradiation range and the irradiation intensity of the two sets of light sources can be adjusted in real time.
Description
Technical field: [0001] The invention relates to an ultraviolet curing device, in particular to an ultraviolet composite light source rapid curing device for a label printing machine. Compared with the traditional ultraviolet curing device, the device is more energy-saving, environmentally friendly, fast and efficient, and can replace the existing label printing The UV curing device of the machine. Background technique: [0002] Curing refers to the process in which inks, coatings, adhesives, sealants, etc. are transformed from a liquid state to a solid state. Ultraviolet curing is a method that uses ultraviolet rays and photoinitiators added to inks, coatings, and sealants to produce photochemical reactions to achieve rapid curing. [0003] The rapid curing of ink in label printing is an important part of the label printing process. However, in the label printing industry, most of the point and line light sources composed of high-pressure mercury lamps and metal halide lamp...
