Abstract
The utility model discloses a gravure immersion inking device, which comprises an impression cylinder and a plate cylinder rolling relative to the impression cylinder. The plate cylinder is embedded into an ink fountain connected with an ink box by the aid of a circulating pipeline, and a pre-scraping blade and a scraping blade are sequentially arranged in the rolling direction of the plate cylinder. By increasing the number of scraping blades from original one to two, the gravure immersion inking device successively scrapes the plate cylinder twice by the aid of the pre-scraping blade and the scraping blade, solves the problem of inking quantity change on the plate cylinder caused by printing speed change, greatly decreases an ink accumulation area between each scraping blade and the plate cylinder, ensures constant contact pressure between each scraping blade and the plate cylinder, and reduces abrasion of parts such as the scraping blades and the like.
Description
Technical field
The utility model relates to a kind of inking device, particularly a kind of gravure immersion type inking device.
Background technology
Traditional gravure immersion type inking device is that plate cylinder directly is immersed in the ink fountain, and printing ink is brought out from ink fountain, makes the double ink foundation roller usefulness of doing of plate cylinder, and is simple and practical, is convenient to regulate.But, this mechanism also comes with some shortcomings: at first, in print speed printing speed not simultaneously, the rotating speed of plate cylinder is also different, this just makes the China ink amount that goes up of plate cylinder also change thereupon, thereby the variation of China ink amount can cause transferring in the printing process quantity of ink on the stock and change and influence print quality, prints because gravure is short black road, makes that this result is more remarkable; Secondly, because doctor and plate cylinder forward are installed, between doctor and forme, can form ink collecting area, thereby wearing and tearing doctor and forme, and the variation of China ink amount also can cause the variation of ink collecting area size, thereby further influence the stability of the pressure between doctor and the forme, in addition when high speed printing, it is big that ink collecting area can become, thereby increase the pressure between cutter and version, aggravated the wearing and tearing between doctor and the forme, last, in printing process, printing ink in the ink fountain remains static, if overlong time makes the uniformity variation of printing ink easily, the viscosity that also may cause printing ink increases and problem such as skinning, and these problems will be printed much larger than the isometric black road of offset printing for the influence of short black road printing.
The utility model content
The technical problems to be solved in the utility model is: at the shortcoming and deficiency that prior art exists, provide a kind of gravure immersion type inking device that can improve printing ink uniformity, minimizing doctor and forme wearing and tearing, improve print quality.
For achieving the above object, the utility model adopts following technical scheme: comprise impression cylinder and with the plate cylinder of impression cylinder to rolling, plate cylinder is embedded on the ink fountain, ink fountain links to each other with black case by circulating line, is disposed with pre-doctor and doctor on the rotating direction of plate cylinder.
Described black case is an enclosed construction, is provided with in the black case and stirs device for ink.
1/3 of described plate cylinder is immersed in the interior printing ink of ink fountain.
The bottom of described ink fountain is the inclined-plane.
The beneficial effects of the utility model are embodied in: the gravure immersion type inking device increases to two with the quantity of doctor by original one, by pre-doctor, doctor plate cylinder is carried out twice wiping of priority, the problem of inking quantitative changeization on the plate cylinder that has solved the print speed printing speed variation and caused, not only significantly reduced the ink collecting area between doctor and the plate cylinder, guaranteed that both contact the constant of pressure, reduced the wearing and tearing of parts such as doctor, and solved in the past because the problem that the printing quality that the inking quantitative changeization is caused descends.
Description of drawings
Fig. 1 is the overall structure schematic diagram of the utility model embodiment.
The specific embodiment
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.
The utility model comprise impression cylinder 4 and with 4 pairs of plate cylinders that roll 3 of impression cylinder, plate cylinder 3 is embedded on the ink fountain 2, the bottom of ink fountain 2 is the inclined-plane, 1/3 of plate cylinder 3 is immersed in the printing ink in the ink fountain 2, ink fountain 2 links to each other with black case 1 by circulating line 7, China ink case 1 is an enclosed construction, is provided with in the black case 1 and stirs device for ink 8, is disposed with pre-doctor 6 and doctor 5 on the rotating direction of plate cylinder 3.
During inking, plate cylinder rotates and printing ink is taken out of from ink fountain 2, printing ink on the plate cylinder 3 has been spread to black layer of the printing ink of thickness homogeneous earlier by pre-doctor 6 down by the position, and then lean on last doctor 5 to contact with the position and finish wiping, printing ink China ink layer through the secondary wiping prints to stock under the effect of impression cylinder 4, by pre-doctor 6,5 pairs of plate cylinders of doctor 3 carry out twice wiping of priority, the problem of the inking quantitative changeization that has solved the print speed printing speed variation and caused, the wiping in advance of simultaneously pre-doctor 6 has reduced the China ink amount on the plate cylinder 3, significantly reduced the ink collecting area between doctor 5 and the plate cylinder 3, guaranteed that both contact the constant of pressure, have reduced the wearing and tearing of parts.
Printing ink in the China ink case 1 carries out flow at high speed by the stirring of stirring device for ink 8, and circulate at black case 1 and 2 of ink fountains by circulating line 7, simultaneously because ink fountain 2 bottoms are the inclined-plane, the printing ink that enters ink fountain 2 is lifted earlier according to ramp structure, sink by the gravity effect then, like this, printing ink has not only kept flowability and cyclicity in the circulatory system that ink fountain 2 and black case 1 constitute, simultaneously inclined-plane, the bottom structure by ink fountain 2 has been finished the flow circuit process in ink fountain 2, has thoroughly solved in the past printing ink in long-time static and inhomogeneities and skin effect phenomenon that occur.In addition, because the continuous motion of printing ink, the viscosity of printing ink is descended, make plate cylinder 3 inkings more even, the China ink layer is thinner, helps wiping and printing, and, because stir in the black case 1 that device for ink 8 is installed in sealing, rather than be directly installed in the ink fountain 2, make that printing ink can be too not high and splash because of stirring the device for ink rotating speed.
