Description of drawings
Accompanying drawing 1 is a pneumatic ink-feeding device structural representation of the present invention.
Accompanying drawing acceptance of the bid keep the score state as follows: 1-coining roller; 2-gravure forme; The 3-scraper; The 4-ink tank; The 5-ink reclaiming pipe; The 6-ink tank; The 7-paper tape; 8-ink supply pipe; 9-printing ink; The pneumatic black cylinder of 10-; 11-ink supply suction pipe; The 12-agitator air.
The specific embodiment
Below the relevant technologies problem is described in further detail, and in conjunction with the accompanying drawings the specific embodiment of the present invention is made detailed description.Be noted that at first frosted printing alleged among the present invention has been a mature technology of the prior art, in multi-field, be applied.Its principle and process are: a kind of UV light-curable ink is printed onto on the paper, under ultraviolet light (UV) irradiation, make printing ink obtain solidifying (promptly dry) again, the ink particle of staying on the paper presents the etched effect of a kind of metalloid, so claim this type of to be printed as the frosted printing.Wherein employed UV light-curable ink has been matured product of the prior art, and existing diversified UV light-curable ink product emerges.A difficult problem of the prior art is though had varied UV light-curable ink product, also to have had the ripe method that the UV light-curable ink is formed the ground-glass appearance frosted finish effect.But (seeing that application number is the Chinese patent application of 2005100325517 denominations of invention for " large tracts of land frosted and specular light become the technology of antifalse effect pattern ") also only adopted in large tracts of land frosted printing described in the prior art in serigraphy; because most of serigraphys are all printed one by one; the quantity of ink that it uses is more; printed layers is thicker; large tracts of land flower version problem can solve than being easier to; and; in case occur that silk screen is blocked or printing ink generation problem; can shut down and handle (screen printer is 3 thousand sheets per hour generally, can shut down at any time).And intaglio printing press is stock with the roll web, and intaglio printing press is in case start is (intaglio printing press is produced continuously, 120 meters on per minute seal) that can not shut down easily, and shutdown can cause bigger economic loss.On the other hand, if adopt intaglio printing press to carry out large tracts of land frosted printing, the quantity of ink that it uses is few, and printed layers is thinner, and the possibility that produces the flower version is much bigger than silk-screen.And, carry out the frosted printing with intaglio printing press and roll web, in case produce the flower version, the percent defective in the product will be surprising, economic loss will be very heavy.Therefore, the technical problem to be solved in the present invention is exactly how stably to transfer to the UV frosted ink on the printed matter, for this reason, the applicant has carried out many tests, the rule of UV light-curable ink and the characteristics that intaglio printing press printing ink shifts have been found, thereby proposed to be applicable to the technical measures of gravure, the characteristics that UV light-curable ink rule and intaglio printing press printing ink are shifted combine, and have finished the present invention.
Described frosted printing is by forming behind the particle photocuring in the printing ink, and for the uniformity that guarantees frosted finish effect and the fineness of printed article, we have selected the very little UV light-curable ink of particle size distribution range for use.But the particle diameter distribution always can not be on all four in the printing ink, and along with the carrying out of printing process, the sand powder of tiny particle diameter can preferentially be transferred, and the ratio regular meeting of ink-well medium coarse sand powder progressively increases, at this moment the sand sense grow on the printed matter.For the aesthetic property of frosted printed matter, in the frosted printing in the frosted ink the conforming requirement of particle diameter very high, when in silk-screen frosted printing, running into this situation, can shut down the replacing new ink.And in gravure was produced, shutdown can cause a certain amount of spillage of material, cheap for the continuity that guarantees to produce and production cost, and we have adopted the method for adding sand sense replenishers, and adopting the less printing ink of the same type of particle diameter is sand sense replenishers.
Gravure is frosted ink to be transferred to the middle boundary thing of paper, the ink cell openings of sizes of the quality of frosted finish effect and gravure and version is dark directly links to each other, the present invention adopts electronics or the meticulous engraving of laser, according to different picture and text types, adopt different ink cell openings of sizes and version dark, guarantee that printing ink transfers to the accuracy on the paper, thereby satisfy the fineness of printed matter frosted finish effect.
The viscosity of UV light-curable ink is higher, and the traditional ink feeding system that uses on the intaglio printing press is an electrodynamic pump, and there is the ink supply defect of insufficient in electrodynamic pump for the UV light-curable ink, very easily causes frosted flower version.The present invention adopts air driven pump ink supply mode, the characteristics of air driven pump ink supply are that each ink supply amount is big, adopt discontinuous ink supply mode, air driven pump is also ceaselessly mixing printing ink in the time of ink supply, and this helps the abundant mixing of the sand powder of various particle diameters in the frosted ink.
