A led-uv curing varnish machine

Abstract

The invention discloses an LED-UV gloss oil solidifying machine. According to the technical scheme, a rack is successively provided with a film feeding mechanism, a film printing and gloss oil feedingmechanism, a film conveying mechanism, a gloss oil solidifying mechanism and a film discharging mechanism, wherein the film feeding mechanism is used for conveying stacked films into the film printing and gloss oil feeding mechanism; the film printing and gloss oil feeding mechanism is used for printing gloss oil on printing surfaces of the films; the film conveying mechanism is used for receiving the printed films so that the printed films pass through the gloss oil solidifying mechanism and are conveyed into the film discharging mechanism; the gloss oil solidifying mechanism is used for solidifying the gloss oil on the printing surfaces of the films; the gloss oil solidifying mechanism comprises a base mounted on the rack and UV-LED lamp modules distributed on the base; and luminous surfaces of the UV-LED lamp modules are opposite to the printing surfaces of the films. The temperature of the UV-LED lamp modules is low, when the films pass through the UV-LED lamp modules, the circumstance that the films become crisp due to high temperature on the films can be avoided, and the LED-UV gloss oil solidifying machine has the characteristics that the films are protected, and the film solidifying quality is improved.

Description

technical field [0001] The invention relates to the field of varnish machine equipment, in particular to an LED-UV curing varnish machine. Background technique [0002] Plastic box is a kind of packaging box, which refers to the product outer packaging box made of PPC, PVC, PET / APET film, which is processed by a series of processes such as printing, die-cutting, and box gluing. [0003] In the production process of plastic box printing, it is first necessary to smear UV varnish on the film as the bottom layer for protection, and then print colored ink on the film to complete the first step of printing the film. Among them, on the film After the varnish is applied to the film, the varnish needs to be cured so that the varnish forms a film on the surface of the film. [0004] Traditional varnish curing usually adopts the form of high-pressure mercury lamp to cure solvent-based varnish. High-pressure mercury lamp is a kind of ultraviolet curing lamp. High-pressure mercury lamp...

Problems solved by technology

[0004] Traditional varnish curing usually adopts the form of high-pressure mercury lamp to cure solvent-based varnish. High-pressure mercury lamp is a kind of ultraviolet curing lamp. High-pressure mercury lamp means that the mercury vapor pressure is 51-507kPa, and the main emission wavelength is 365.0nm. For a mercury vapor arc lamp with an equivalent energy of 327.3kj / mol, the mercury vapor pressure is 2 to 5 atmospheres when ignited. In the process of curing varnish, the power of a mercury lamp is 9.7kw. Generally, a varnish machine is made of Composed of three mercury lamps, the total power is 29.1kw. Therefore, the high-pressure mercury lamp releases high heat temperature and ozone, which needs to be purified and discharged to the outside. After the film passes through the mercury lamp, the film is better The temperature can easily cause the surface of the film to become brittle due to heat, so there is some improvement
