An energy-saving leduv curing device suitable for metal lithography

Abstract

The invention discloses an energy-saving LEDUV curing device suitable for metal lithographic printing, which includes a base, four support columns are fixedly arranged on the upper end surface of the base, and a set is fixedly arranged on the upper end surface of the support column for providing electric energy to the curing mechanism. The power supply module, one end of the power supply module is provided with a plurality of control buttons, the upper end of the four support columns is fixed with a housing, and the two sides of the housing are provided with a transportation mechanism for transferring the metal plate. By setting the curing mechanism to remove dust before entering the metal lithography, avoid dust entering the metal plate, affecting the printing quality of the metal plate, avoiding the metal plate falling off due to dust during metal lithography, and setting the dust removal component to make the curing After the mechanism is used, it can prevent external dust from entering, which will affect the next use.

Description

technical field [0001] The invention belongs to the field of metal lithographic printing, in particular to an energy-saving LED UV curing device suitable for metal lithographic printing. Background technique [0002] Metal printing (Metal Printing) is a kind of practical printing, commonly known as iron sheet printing, it is a printing method that uses hard materials such as metal plates, metal forming products and metal foils as substrates, and its printing materials mainly include tinplate (plated iron) Tin steel plate), tin-free thin steel plate (chemically treated steel plate TFS), zinc iron plate, black steel plate, aluminum plate, aluminum stamping container and aluminum, white iron sheet composite materials, etc. Surface printing on flat metal is an important step in the production process of metal flat In the process, most of the coatings with excellent process resistance are used, and the ink and coating on the metal surface are cured by curing equipment; [0003] ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, high-pressure mercury lamps are often used for curing, which has low curing efficiency and has an impact on the metal surface. When used for a long time, high temperatures will be generated. In severe cases, the internal circuit of the equipment will be burned, and the life of the UV lamp will be seriously affected. Lamp-type UV curing belongs to surface curing, and inks and coatings cannot be cured deeply, so metal lithographic printing is not completely cured and easy to fall off. However, LEDUV curing devices are used to cure metal lithographic inks, and ultraviolet light with a wavelength of 200-450nm is used as radiation. Energy triggers chemically reactive liquid printing inks and coatings to quickly turn into solids. Under the radiation of ultraviolet light, inks and coatings can be quickly dried and cured within a few seconds. However, long-term use of LEDUV curing devices will cause a series of problems; ( 1) A higher temperature is generated, and the internal circuit of the equipment is burned in severe cases; (2) There are often certain dead angles when the metal plate is irradiated by the light source, and the ink and paint cannot fully receive the light, so that there are some dead angles after metal lithography printing. There are defects in the process of using; (3) when solidifying, after the dust of the outside enters on the metal plate, it will have a certain impact on the printing of the metal plate, and there is no device in the prior art that can solve the problem of the metal plate Solve the above problems when curing
