Energy-saving LED UV curing device suitable for metal flat plate printing

Abstract

The invention discloses an energy-saving LED UV curing device suitable for metal flat plate printing. The energy-saving LED UV curing device suitable for metal flat plate printing comprises a base, four supporting columns are fixedly arranged on the upper end face of the base, a power supply module for providing electric energy for a curing mechanism is fixedly arranged on the upper end faces of the supporting columns, and a plurality of control buttons are arranged on one end face of the power supply module. A shell is fixedly arranged on the upper end faces of the four supporting columns, and a conveying mechanism used for transferring a metal flat plate is arranged on the end faces of the two sides of the shell. According to the energy-saving LED UV curing device, by arranging the curing mechanism, dust is removed before the metal flat plate is printed, it is avoided that dust enters the metal flat plate, and the printing quality of the metal flat plate is affected, and it is avoided that during metal flat plate printing, the metal flat plate falls due to dust; and meanwhile, by arranging a dust removal assembly, after the curing mechanism is used, external dust can be prevented from entering the curing mechanism, and the situation that next use is affected can be avoided.

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
