Direct-injection printing process adopting water-based UV cured ink

Abstract

The invention relates to the field of printing processes, and specifically relates to a direct-injection printing process adopting water-based UV cured ink. The used direct-injection printing device comprises an installation seat, wherein ultraviolet lamps are fixedly installed around the installation seat separately; an ink injection pipe is connected into the installation seat in a sleeved manner; the bottom of the ink injection pipe penetrates through to reach the lower surface of the installation seat; and a lamp pipe is connected into each ultraviolet lamp in a sleeved manner. Through arrangement for an adjustor, a triangular plate is enabled to carry out closing action by rotating a drive gear, the drive gear is rotated by different degrees to adjust a luminous flux, so that passingultraviolet rays are ideally adjusted, influence on curing for a coating layer with a color is more obvious, and the curing speed and curing depth of the printing ink are increased; through arrangement for a light diffuser, conversion for the divergent light rays of a point light source to parallel light rays is facilitated; and in combination with a reflector, re-refraction for inclined light rays which pass through the interiors of the lamp pipes and are unbalanced due to the interference of mercury molecular reflection at the moment that the ultraviolet ray makes critical contact with ink to be cured, is facilitated.

Description

technical field [0001] The invention relates to the field of printing technology, in particular to a water-based UV curing ink direct injection printing technology. Background technique [0002] The printing process is the process of printing patterns on textiles with dyes or pigments. Printing can be divided into fabric printing, top printing and yarn printing, and fabric printing is the main method. Top printing is used to make mixed-color tweed and yarn. Printing is used to weave special styles of colorful patterned fabrics. Water-based UV curable ink is the most commonly used printing ink in the textile industry. The ink is printed on the base paper through a gravure printing machine, and then the paper is printed on the paper under high temperature and high pressure of the thermal transfer printing machine. The pattern is transferred to the textile of polyester material. Its main components are hot melt adhesive, pigment and some additives. Refers to the radiation rate...

Problems solved by technology

[0003] Under the curing of the same UV dose, high-intensity and high-flux UV light sources can increase the curing speed and curing depth. The influence of UV light intensity and high luminous flux on the curing of colored coatings is more obvious, but the existing UV light sources are not It is convenient to precisely adjust the intensity and luminous flux of ultraviolet light; after the high-intensity ultraviolet light is transmitted to the surface of the inkjet object, the ultraviolet light cannot guarantee to reach the irradiation target 100%, which is inconvenient to maximize the utilization rate of ultraviolet light irradiation. The ultraviolet light is formed by mercury vapor As a light source, when the lamp tube is turned on, the mercury liquid will be heated and sublimated into mercury vapor that walks in the lamp tube, but the existing ultraviolet lamp body has a certain risk of loosening and air leakage due to the vibration generated during the inkjet process. The airtightness of the
