Description
Technical field
The invention relates to a kind of mechanical platform for high speed (> 10000 r/h), sheet-fed (perfect printing) Digital ink-jet printer, belongs to printing machinery technical field.
Background technology
Along with the fast development of social informatization, networking, digital ink-jet printing technology will progressively replace conventional litho offset printing.In the past few years, magnetic, e-inks mode digital printing technology relative maturity, digital duplicating machine (Kodak, Fuji, Canon etc.), e-inks digital printer (Hewlett-Packard) are popularized rapidly, and small breadth (below 52 specifications) offset press is subject to enormous impact.Simultaneously digital ink-jet printing technology there has also been tremendous development along with the lifting of ink gun technology, the roll web Digital ink-jet printer of all size is in succession market-oriented, resolution ratio can reach 1200dpi × 1200dpi, and speed can reach 200 m/min, substantially meets colored printing demand in enormous quantities.Have expert to do economic analysis to mode of printing and print amount, magnetic, e-inks mode digital printer are applicable to small lot (short run) printing, maximum economy limitation 1000, and the profit margin that transfinites declines fast; Roll web Digital ink-jet printer is applicable to (long version) in enormous quantities printing, and minimum economic limits the quantity 10000, is less than limitation profit margin and also declines fast.Between two economic limitations of 1000 ~ 10000, it is the effective profit margin of sheet-fed Digital ink-jet printer, in the past few years, everybody is developing sheet-fed Digital ink-jet printer by every means, up till now, Lan Da company of Israel is only had to make a breakthrough, outstanding three sections of (S5, S7, S10) sheet-fed Digital ink-jet printer in exhibition are printed in Wu Yue, 2012 De Luba, the highest print speed printing speed 11000 r/h, create a wonderful sensation, although its technology is still needed perfect, be enough to declare publicly digital printing technology and likely replace traditional offset printing in the near future.
Lan Da company sheet-fed Digital ink-jet printer structure is mainly divided into four major parts: control system, ink-jet system, transfer printing belt, transfer printing platform, sees accompanying drawing 5.In accompanying drawing figure: 11 is ink-jet system, 12 for transfer printing belt, and 13 is pressure roller, and 14 ~ 19 is the drum segment of transfer printing platform, and 20 is paper collecting mechanism.Ink is sprayed on transfer printing belt surface assigned address by ink-jet system, rolls 15,19 clutches and completes transfer printing, under contact effect, ink 100% is transferred in paper surface in transfer printing belt rotary course by pressure roller 13 and impression.Transfer printing platform adopts the defeated paper of traditional two color offset press, transfer, collection frame for movement, when being printed on one side, transfer printing belt only roll with impression 15 clutches (face of rolling is closed, roll mouth from, impress and roll the clutch secondary that circles); During printed on both sides, transfer printing belt by regulation order and impression roll 15,19 clutches (face of rolling is closed, roll mouth from, impression roll circle clutch once), by upset cylinder 18 realize printed on both sides.Because transfer printing belt lateral attitude when running up can offset, particularly during high speed printing, transfer printing belt and impression roll alternately clutch pressure and can produce fluctuation, this can cause ink picture transfer position precision not high, is difficult to the requirement reaching 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 Mechanical platform of digital ink-jet printer of single sheet.This ink-jet printer mechanical platform does not adopt transfer printing belt, and adopt cylinder transfer modes to realize transfer printing function, transfer printing precision is high.
The invention is achieved through the following technical solutions: Mechanical platform of digital ink-jet printer of single sheet is formed primarily of support, paper supply unit, printing transfer printing unit, delivery unit four part; It is characterized in that: described printing transfer printing unit is overturn cylinder formed by four times of footpath transfer platen, two two-around impression cylinders, two-around transfer roller, a two-around upset cylinder and single times of footpaths, four times of described footpath transfer platen and two two-around impression cylinder star arrangement, the first two-around impression cylinder, two-around transfer roller, two-around upset cylinder, single times of footpath upset cylinder, the second two-around impression cylinder is V-shaped is in turn arranged in below four times of footpath transfer platen.
With the axle center of four times of footpath transfer platen for summit, 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 °; With the axle center of the first two-around impression cylinder for summit, 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, line angle β scope is between 70 ° ~ 90 °; With the axle center of the second two-around impression cylinder for summit, 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 times of footpath upset cylinder is between 70 ° ~ 90 °.
Described impression cylinder installs lining plank.
Lining plank thickness is 0.5 ~ 1.5mm.
The beneficial effect of the invention: the invention adopts said structure, by the permutation and combination of the associated drum such as transfer platen, two impression cylinders, do not adopt transfer printing belt, cylinder transfer modes is adopted to realize transfer printing function, transfer printing precision is high, can realize printing position error and be less than 0.1 mm, if the ink gun jet speed of equipped ink-jet system reaches 150m/min, and ink 100% can be realized shift, get final product commercialization.Impression cylinder installs additional the lining plank of 0.5 ~ 1.5mm, single, double surface printing conversion can be realized.
