The utility model discloses the production environment can be improved, the security that the material used is improved to reduce production processes, improved production efficiency.
Description
Technical field
The utility model relates to environment-friendly cigarette materials application field, specifically a kind of printing equipment.
Background technology
Cigarette tipping paper refers to: cigarette filter tip and Cigarette are hinged with the dedicated paper got up.In cigarette industry is produced, cigarette tipping paper is absolutely necessary a kind of paper wrapper, often need to adopt gilding technology in this material, description this cigarette product LOGO(pattern and word) thermoprint at tipping paper, form the trade mark feature of clear-cut individuality.
UV(ultraviolet light polymerization) ink refers under Ultraviolet radiation, utilizes different wave length and the ultraviolet light of energy to make the monomer polymerization in ink adhesive become polymer, makes ink film forming and dry ink.The main cause of UV solidification is due to ultraviolet effect, under ultraviolet irradiation, Photoepolymerizationinitiater initiater in UV ink transfers free state molecule to after absorbing certain wavelength photons, become free radical, then by the transmission of intermolecular energy, make polymerizing prepolymer and sensing optical activity monomer become excitation state, produce charge-transfer complexation body, continuous cross-linked polymeric between complexing body, film-forming.The solidification process of UV ink is a photochemically reactive process, namely under the effect of ultraviolet energy, prepolymer film-forming within the extremely short time, ultraviolet is except the surface solidification causing ink, more can permeate and go deep in aqueous ultraviolet curing ink, and stimulate the further solidification of deep layer ink film.
Gold stampingly also crying " thermoprint ", is a kind of printing decoration technique.It is heated by metallic plate, executes paper tinsel, printed matter impresses out word or the pattern of gold, silver color or other color.Developing rapidly and extensive use or the thing of nearly more than ten years of thermoprint technology.Thermoprint technology is of wide application, as paper product thermoprint, and textile thermoprint, the thermoprint of art work, plastic products thermoprint etc.
Gilding technology is the principle utilizing hot pressing to shift, and the aluminium lamination in anodized aluminium is transferred to stock surface to form special metal effect, the main material of gold stamping use is electrochemical aluminum foil.Electrochemical aluminum foil is made up of multilayer material usually, and base material is often PE, is secondly to be separated coating, color coating, metal coating (aluminizing) and function of glue coating.This shows, gilding technology is complicated, cost is higher, gold stamping complete after can form a large amount of discarded object, and these discarded objects non-environmental protection material that is some mostly, gold stamping itself also exist certain potential safety hazard, as the solvent in metal complex dyes, adhesive and residual list etc., gold stamping in improvement, contribution is outstanding in appearance, but but have ignored the impact for environmental protection and safety in utilization.
In order to meet cigarette tipping paper requirement high-grade attractive in appearance, cigarette enterprise often carries out gold stamping on tipping paper.Gold stamping have many advantages: clear patterns, attractive in appearance, and color glow is wear-resisting, weather-proof.Gold stamping in planar design, can play the effect of crucial touch, outstanding design motif, especially on trade mark, login name, effect is more remarkable.The gold stamping cigarette tipping paper that is applied to also is thing in nearly more than ten years, is particularly applied on some high-end products, the general technique adopting blanching, the anodized aluminium material after painted subtly thermoprint in the lower end of tipping paper, the trade mark of outstanding product and title.But the content of gold stamping heavy metal is high, and adhesive need be adopted, is separated the organic chemicals such as coating, VOCs and residual single harm large.And after tipping paper background color and complexion print, need to transfer to gold stamping device carries out gold stamping, complex process.
UV ink has the characteristic to UV light selective absorbing, and under the irradiation of UV light, UV ink Photoepolymerizationinitiater initiater absorbs the photon of certain wavelength, is energized into excitation state, forms free radical or ion.Then by intermolecular energy trasfer, the prepolymer of polymerization and light activated monomer and polymer is made to become excitation state, the charge-transfer complex of generation.The continuous cross-linked polymeric of particle of these complexity, film-forming.The film forming of UV ink is chemical action, monomer and polymer polymerization reaction take place under the effect of initator; And the film forming of traditional ink is physical action, resin has been condensate, and the dissolution of polymer of solid is become aqueous polymer by solvent, and print is coated with on the substrate, and then solvent is through volatilizing or being absorbed, and makes aqueous polymer revert back to original solid-state shape again.
It has been ripe technology that UV ink is applied to tobacco bale, but, UV ink is applied to cigarette tipping paper and did not also meet research report, UV printing is generally used for the printing of label paper, tipping paper is thinner, and the UV typography that the ground paper that existing grammes per square metre is large is opened is not suitable for the printing that this thin paper of tipping paper is opened.
Summary of the invention
