Abstract
The invention discloses a satellite intaglio printing method, which is performed according to following steps that a printed material passes through a swing roller in a traction unit from a discharging unit and enters a corona treatment unit for corona treatment after tension achieves a preset state, then the printed material is subjected to ground color printing after entering a single coating unit, a coating drying unit dries the printed material, the printed material attached with ground color enters a satellite intaglio printing unit for four-color printing, then a top drying unit bakes the printed material, the temperature of the dried printed material is reduced by a top water cooling unit, the printed material is subjected to deep line embossing treatment by a deep line embossing unit, and a heating unit is used in the deep line embossing process, so the lines of the printed material are clearer, then the printed material passes through a secondary water cooling unit, the printing embossing process is finished, and the well-printed printed material passes through an edge cutting unit, and is coiled by a large coiling unit and shaped. The satellite intaglio printing method solves the problem that the technical requirements of multicolor and precise overprinting of a direct printing process cannot be met.
Description
Technical field
The invention belongs to textile printing technical field, be specifically related to a kind of satellite-type gravure process.
Background technology
The existing leather pattern-printing stamp mode of heat transfer that adopts has been come more, its basic technology is: after the printing thin film be printed as by dispersed color and surface treatment, the leather of harvest volume enters hot transfer respectively, by the decalcomania heat sublimation in high temperature film on leather, complete leather transfer printing, the deficiency of this printing technology is, first need to be utilized by ink unit type intaglio press to print on OPP film, and then transfer printing on heat transfer machine, point two processing steps are needed, middle transfer vector OPP film cannot reuse, uneconomical environmental protection, and thermal transfer printing hourly velocity is low, the stamp speed of tens meters per minute can only be reached.
On the basis of leather transfer printing mode, the mode of direct printing is created gradually between industry, unit type intaglio press is utilized directly to carry out stamp to leather exactly, the benefit of this printing technology is adopted to be do not need OPP film to serve as offset medium, cost greatly can be reduced, economic environmental protection, and stamp speed also has a distinct increment, and can reach 40 meters per minute.But due to the easy draftability of leather, often there is chromatography and forbidden phenomenon in the pattern adopting direct printing technique to print.Therefore, current leather direct printing mainly based on monochromatic or the double-colored pattern not needing chromatography, and more than three looks needs the printing technique of accurate overprinting also to belong to blank in field of printing and dyeing.
Summary of the invention
The object of this invention is to provide a kind of satellite-type gravure process, solve the problem that can not meet direct printing technique polychrome, accurate overprinting technical requirement existed in prior art.
The technical solution used in the present invention is, satellite-type gravure process, specifically implement according to following steps: stock is from the pendulum roller of blowing unit through traction unit, enter sided corona treatment unit after making tension force reach predetermined state and carry out sided corona treatment, enter independent coater unit afterwards and stock is carried out background color printing, then be coated with drying unit and be dried process, enter into after satellite-type intaglio printing unit carries out four look stamps with the stock of background color, then stock is dried by top drying unit, stock is dried again after top water cooling unit makes its temperature decline, dark embossed is carried out again through dark embossing unit, heating unit is attended by dark embossed process, make stock lines more clear like this, again after secondary water cooling unit, printed pattern process completes, printed stock is carried out cutting edge unit, finally receive large roll unit by shaping for its rolling.
Feature of the present invention is also,
Leather after oven dry carries out stamp, leather enters in satellite-type intaglio printing unit, leather is tightly coated on breast roll, breast roll is rubber rollers, in printing process, breast roll operates together with leather, leather rotating speed is synchronous with printing plate cylinder, and whole satellite-type intaglio printing unit is by driven by servomotor, and stamp process controls automatically.
The easy draftability of leather causes the control of tension force stricter, blowing unit and traction unit realize the control of tension force by putting roller, traction unit and the coater unit be connected successively thereafter, satellite-type intaglio printing unit, top water cooling unit, dark embossing unit, cutting edge unit between any two by tension-sensing roller to realize the control of tension force, cutting edge unit realizes the control of tension force by putting roller with receiving large roll unit.
Ink big world, the Dongguan ink that printing uses, coordinates butanone and butyl ester, makes its viscosity reach 30.
During printing, of the same colour, two looks, three look drying units temperature controls at 60 DEG C ~ 80 DEG C; During embossing, the temperature of knurling rolls controls at 100 DEG C ~ 150 DEG C.
Stock after sided corona treatment unit sided corona treatment enters independently coating and printing unit, stock is carried out background color coating and printing, after background color coating and printing completes, utilize coating drying unit to dry the stock after completing background color coating and printing, then enter into satellite-type printing cell.
The invention has the beneficial effects as follows, by the mode of satellite-type intaglio printing, directly printing-ink is printed onto leather surface, use after drying, this printing technology is simple, easy to operate, the above direct printing of the five colors can be carried out, and chromatography precision is high, print speed printing speed can reach more than 50 meters per minute, it is four times of existing transfering printing process, and do not need high temperature to shift, ink is dried, and save the use of OPP film in existing process transfer stamp, reduce production cost and simplify technological process, it is a kind of economic environmental protection, high-grade, leather pattern-printing scheme at a high speed.
