Description

The digital thermoprint module of a kind of high speed UV

Technical field

The utility model relates to thermoprint field, particularly relates to the digital thermoprint module of a kind of high speed UV.

Background technology

Along with the raising of national economy, the development of press-packaging industry, people require top grade, fineness, environmental protection, are rich in personalization the external packing of product, and in the post-press finishing of packaging product, hot stamping process is liked by people because of its unique surface finish effect always.

Gold stampingly mainly contain three kinds of functions, the one, incrustation, gold stamping picture and text present strong metallic luster, color glow, will never fade.Especially gold stamping silver, printed matter surface has been interspersed in splendid with it, exquisite graceful decoration, strengthen the artistry of printing, play the effect of publicity of projecting motif, and its bright degree has substantially exceeded bronze printing and Yin Yin, make product there is high-grade sensation and give beautiful enjoyment, greatly having improved value-added content of product.The 2nd, give product higher anti-counterfeiting performance, adopt holographic locating thermoprint trademark, anti-counterfeiting, guarantor's famous brand; The 3rd, protection printing, because gold stamping layer has good physics, chemical property, printing product plays a very good protection.

But current gilding technology also exists limitation: the preparation of printing plate causes thermoprint process time to be grown, operation is many, high pollution, cannot realize large area, cannot realize one and play thermoprint, cannot realize printing and get, therefore, gilding technology can't be applied to the incrustation of the common advertising carriers of advertising sector such as large format placard, personalized wall calendar, post stand.

Modal gilding technology comprises blanching gold and cold wave gold.

Tradition blanching gold

The main material of blanching gold is anodized aluminium (also claiming gold and silver paper tinsel or gilding film), it is taking mylar as sheet base, coat alcohol dissolubility dyeing resin layer, through vacuum-metallize aluminium, coat adhesive layer again and make, being formed by base membrane layer, alcohol dissolubility dyeing resin layer (can be divided into again separation layer, dye layer), aluminium lamination and adhesive layer.Base membrane layer is other carrier of each layer of electrochemical aluminum foil, plays supporting role, and base membrane layer material used is the thick mylar of 12~16 μ m; It is easily separated when separation layer can make the dye layer of electrochemical aluminum foil and base membrane layer thermoprint; Dye layer is in order to show the color of electrochemical aluminum foil, and it is made up of with dyestuff melamine air aldehyde resin, organic siliconresin etc.; Aluminium coated can make electrochemical aluminum foil present the gloss as metal, and aluminium is good light reflecting material, and gaseous aluminum can be attached to equably dye layer surface under vacuum; Adhesive layer is mainly made up of methacrylate or shellac, in order to make electrochemical aluminum foil coated adhesive to printable fabric when the thermoprint, and plays protection aluminium coated.

The technological process of blanching gold comprises: lock up → make-ready → hot pressing → peel off → waste discharge

Its technique is mainly the principle of utilizing hot pressing to shift.Under combined pressure effect, anodized aluminium contacts with printing plate, stock, because making printing plate, the intensification of electric hot plate there is certain heat, after being heated, anodized aluminium makes dyeing resin layer and the adhesive fusing of hot melt, dyeing resin layer viscous force reduces, and viscosity increases after the fusing of special heat-sensitive adhesive, aluminium lamination and basement membrane have been transferred on stock when peeling off, along with the removal of pressure, the rapid cooling curing of adhesive, thermoprint layer is firm.

The technical disadvantages of blanching gold: printing plate mask-making technology complexity, consuming time, power consumption, high pollution, traditional blanching flexible operation degree is poor simultaneously.

Traditional cold is gold stamping

The anodized aluminium that cold wave gold uses is a kind of extraordinary anodized aluminium, not gluing of its back side, adhesive was directly coated on the position that base material need to decorate in when printing, and when transfer, anodized aluminium contacts with adhesive, under the effect of adhesive, anodized aluminium is also attached on printed matter surface.

Cold stamping process flow process comprises: lock up → applying glue → cold pressing → peel off → waste discharge

Its technique is mainly to utilize the principle of colding pressing and peeling off.Printing UV ink, needs gold stamping position to print extraordinary adhesive in ink pellet surface---UV cure adhesive; Then pass through UV drying device by the moisture removal of adhesive to a certain extent, form full-bodied, the very thin pressure sensitive adhesive of one deck; Then, start cold wave gold, under the effect of pair of metal cylinder, aluminium foil is integrated with adhesive contact pressing.Because adhesive is large with putting forward cohesive force between aluminium foil, so when waste discharge, printed matter surface is stayed at the position that aluminium foil contacts with adhesive, become one with printed matter, the other parts of aluminium foil are with waste discharge traditional blanching gold.

The technical disadvantages of cold wave gold: in the time of printed matter surface application of adhesive, as adopted offset printing must prepare forme; Print adhesive as adopted and must adopt special UV flat-panel printer, this flat-panel printer price exceedes 1,000,000, UV curing apparatus has ozone discharge, ultraviolet ray large to human injury, and operational danger is high, and pressing, receiving/releasing volume complicated operation

Utility model content

The technical problems to be solved in the utility model be to provide a kind of simple in structure, cost is low, easy and simple to handle, automaticity is high, convenient and swift, the digital thermoprint module of the high speed UV that can be used in conjunction with other printing machines.

For reaching above-mentioned purpose, the digital thermoprint module of a kind of high speed UV of the utility model, described module comprises let off roll, wind-up roll, thermoprint roller, high velocity projector and UV drying box, described let off roll and described wind-up roll are for the transmission of cold stamping film, between described let off roll and described wind-up roll, be provided with described thermoprint roller, described cold stamping film one side and described thermoprint roll-in are tight, opposite side is provided with described UV drying box, carrying out thermoprint for the ultraviolet irradiation of thermoprint process solidifies, described thermoprint roller upstream is provided with high velocity projector, for the glue spraying before roll web thermoprint.

Wherein also comprise the cold stamping film transfer roller between described let off roll and described wind-up roll, for cold stamping film is transmitted and supported.
