Description
Technical field
The invention relates to a kind of at a high speed (mechanical platform of＞10000 r/h), sheet-fed (perfect printing) digital ink-jet printing machine belongs to the printing machinery technical field.
Background technology
Along with the fast development of social informatization, networking, the digital ink-jet printing technology will progressively replace traditional offset lithography technology.In the past few years, magnetic, e-inks mode digital printing technology are ripe relatively, and digital duplicating machine (Kodak, Fuji, Canon etc.), e-inks digital printer (Hewlett-Packard) are popularized rapidly, and small breadth (52 specifications are following) offset press is subjected to enormous impact.The digital ink-jet printing technology is along with the lifting of ink gun technology has also had tremendous development simultaneously, the roll web digital ink-jet printing machine of all size is the marketization in succession, resolution ratio can reach 1200dpi * 1200dpi, and speed can reach 200 m/min, satisfies colored printing demand in enormous quantities substantially.Have the expert that mode of printing and seal amount were done economic analysis, magnetic, e-inks mode digital printer are fit to small lot (short run) printing, and maximum economy is limited the quantity of 1000, and the profit margin that transfinites descends fast; Printing that roll web digital ink-jet printing machine is fit to (long version) in enormous quantities, minimum economic is limited the quantity of 10000, is less than the profit margin of limiting the quantity of and also descends fast.Between two economy of 1000 ~ 10000 are limited the quantity of, it is the effective profit margin of sheet-fed digital ink-jet printing machine, in the past few years, everybody is developing sheet-fed digital ink-jet printing machine by every means, up till now, have only Israel Lan Da company to make a breakthrough, at outstanding three (S5, S7, S10) the sheet-fed digital ink-jet printing machine of in Wu Yue, 2012 De Luba printing exhibition, the highest print speed printing speed 11000 r/h, create a wonderful sensation, though it is perfect that its technology is still needed, be enough to declare publicly the digital printing technology and might replace traditional offset printing in the near future.
Lan Da company sheet-fed digital ink-jet press structure mainly is divided into four major parts: control system, ink-jet system, transfer printing belt, transfer printing platform, see accompanying drawing 5.Among the accompanying drawing figure: 11 is ink-jet system, and 12 are the transfer printing belt, and 13 is pressure roller, and 14 ~ 19 are the drum segment of transfer printing platform, and 20 is paper collecting mechanism.Ink-jet system is sprayed on transfer printing belt surface assigned address with printing ink, roll 15,19 clutches by pressure roller 13 and impression in the transfer printing belt rotary course and finish transfer printing, under the effect of contact pressure with printing ink 100% transfer printing at paper surface.The transfer printing platform adopts traditional two color offset press to fail paper, transfer, collection frame for movement, when being printed on one side, the transfer printing belt only with impression roll 15 clutches (face of rolling closes, roll mouthful from, impression rolls the clutch secondary that circles); During printed on both sides, the transfer printing belt in accordance with regulations order and impression roll 15,19 clutches (face of rolling closes, roll mouthful from, impression rolls and circles clutch once), realize printeds on both sides by upset cylinder 18.Because transfer printing belt lateral attitude when running up can be offset, particularly transfer printing belt and impression roll alternately that the clutch pressure can produce fluctuation during high speed printing, this can cause printing ink picture transfer position precision not high, is difficult to reach the requirement of colored printing, is difficult to commercialization.
Summary of the invention
In order to solve the technical problem of above-mentioned existence, the invention provides a kind of sheet-fed digital ink-jet printing machine mechanical platform.This ink-jet printer mechanical platform does not adopt the transfer printing belt, adopts cylinder transfer printing mode to realize the transfer printing function, the transfer printing precision height.
The invention is achieved through the following technical solutions: sheet-fed digital ink-jet printing machine mechanical platform mainly is made of support, paper supply unit, printing transfer printing unit, delivery unit four parts; It is characterized in that: described printing transfer printing unit be by one four times footpath transfer platen, two two-around impression cylinders, two-around transfer roller, two-around upset cylinder and list doubly the footpath cylinder that overturns constitute, described four times of footpath transfer platen and two two-around impression cylinder stars are arranged, the first two-around impression cylinder, two-around transfer roller, two-around upset cylinder, single cylinder, the second two-around impression cylinder V-shaped transfer platen below, four times of footpaths that is arranged in turn of doubly directly overturning.
Axle center with four times of footpath transfer platen is the summit, and the axial connecting line angle α scope of two two-around impression cylinders that the axle center of four times of footpath transfer platen is adjacent is between 110 ° ~ 140 °; Axle center with the first two-around impression cylinder is the summit, and line angle β scope is between 70 ° ~ 90 ° between four times of footpath transfer platen that the axle center of the first two-around impression cylinder is adjacent, the axle center of two-around transfer roller; Axle center with the second two-around impression cylinder is the summit, and the axial connecting line angle γ scope of four times of footpath transfer platen that the axle center of the second two-around impression cylinder is adjacent, single cylinder that doubly directly overturns is between 70 ° ~ 90 °.
On the described impression cylinder lining plank is installed.
Lining plank thickness is 0.5 ~ 1.5mm.
The beneficial effect of the invention: said structure is adopted in the invention, permutation and combination by transfer platen, two relevant cylinders such as impression cylinder, do not adopt the transfer printing belt, adopt cylinder transfer printing mode to realize the transfer printing function, the transfer printing precision height can be realized the printing position error less than 0.1 mm, if the ink gun jet speed of equipped ink-jet system reaches 150m/min, and can realize that printing ink 100% shifts, and gets final product commercialization.Install the lining plank of 0.5 ~ 1.5mm additional at impression cylinder, can realize single, double printing conversion.
