Abstract
The utility model relates to an electrostatic ink absorbing device, which comprises an electrostatic pressure printing roller, a discharge component, a high pressure generator, electrostatic eliminating rods and a gravure printing edition roller, wherein the high pressure generator is connected with the discharge component and the electrostatic eliminating rods; the discharge component is connected with the electrostatic pressure printing roller; the electrostatic pressure printing roller is positioned above the gravure printing edition roller; a printed object penetrates through the space between the electrostatic pressure printing roller and the gravure printing edition roller; and the two electrostatic eliminating rods are respectively mounted on the front side and the rear side of a position wherein the printed object enters into an electrostatic pressure printing rubber roller. By adopting the electrostatic ink absorbing device provided by the utility model, the ink transfer rate is upgraded from about 40 percent of a traditional mode to 90 to 100 percent, and the ink is saved by 5 to 7 percent.
Description
Technical field
The utility model belongs to printing technology, relates to gravure printing apparatus, especially a kind of static blotter.
Background technology
Intaglio printing is called for short gravure, is four big mode of printings a kind of mode of printings wherein.Intaglio printing is a kind of direct printing process, it is imprinted directly into printing ink contained in the intaglio plate pit on the intaglio printing schematic diagram thing of undertaking the printing of, the deep or light level of institute's print face is to be determined by the size of pit and the depth, if pit is darker, the printing ink that then contains is more, and the China ink layer that stays on the stock of impression back is just thicker; If opposite pit is more shallow, the quantity of ink that then contains is just less, and the China ink layer that stays on the stock of impression back is just thinner.The forme of intaglio printing is by forming with the surface of corresponding pit of original copy picture and text and forme one by one.During printing, printing ink is filled in the pit, and the printing ink on forme surface is wiped off with doctor, and forme contacts with the pressure of stock Zhi Yiding, and the printing ink in the pit is transferred on the stock, finishes printing.The forme of intaglio printing in modern age mostly is produced on round cylinder surface, adopts circle to press the mode of printing of circle.Usually impression cylinder is last, and gravure printing roller is following.The gravure printing roller bottom is immersed in the ink tank, and the space of a whole page is obtained printing ink (also useful pump ink-jet or give the space of a whole page by the ink roller ink transfer that is immersed in the black groove) from groove.China ink groove top is provided with the stalloy scraper and is pressed in the gravure printing roller surface, strikes off the printing ink (also useful counter-rotating wipe ink roller cleans) at no picture and text place on the space of a whole page.Reside in the printing ink in the space of a whole page picture and text inking hole (or line), when forwarding the tangent place of two cylinders to, transfer on the paper (plastic foil, aluminium foil etc.) by this place, print off picture and text.
Owing to the fineness of paper, humidity, the viscosity of printing ink, the multiple reasons such as density of site; stock " hickie " occur through regular meeting; printing ink in the gravure printing roller space of a whole page can not discharge fully; sometimes have only about 70%; therefore install the transfer amount that the static blotter improves printing ink additional, thereby improve the effect of printing greatly.The advantage that installs the static blotter additional can also reduce the pressure of printing also not only in this, prolongs the working life of printing machine.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of static blotter is provided, and improves printing quality, improves printing efficiency.
The technical scheme that the utility model is taked is:
A kind of static blotter comprises static roller platen, discharge assembly, high pressure generator, static elimination rod, gravure printing roller, and it is characterized in that: described high pressure generator is eliminated rod with discharge assembly and static respectively and is connected; Described discharge assembly is connected with the static roller platen; Described static roller platen is positioned at the top of gravure printing roller, and stock passes between static roller platen and gravure printing roller; Described static is eliminated rod two, is installed in the front and back position that stock enters the electrostatic pressure glue-printing roller respectively.
Further, described discharge assembly is built-in with spherical spring, and spherical spring contacts with the bearing of described static roller platen, the bearing insulation against ground of static roller platen.
The beneficial effects of the utility model are:
1, preventing to occur losing China ink (showing money or valuables one carries unintentionally) on paper or the film, mainly is on middle light color;
2, because of reducing the horizontal pressure force of impression cylinder, increase the service life of impression cylinder;
3, better obtain higher print speed printing speed under the printing quality;
4, on minimum degree, do not influence the printing density of unit are;
5, realize about 40% the liftings to 90%-100% of printing ink rate of rotation from traditional approach, printing ink saving rate reaches 5%-7%.
Description of drawings
Fig. 1 is the utility model structural representation
Fig. 2 is discharge assembly and static roller platen scheme of installation
Wherein:
1, high pressure generator 4, static roller platen
2, discharge assembly 5, gravure printing roller
3, static is eliminated rod 6, stock
The specific embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
As shown in Figure 1, 2, the static blotter is made up of static roller platen 4, discharge assembly 2, high pressure generator 1, static elimination rod 3 etc.Wherein the static roller platen is positioned at gravure printing roller 5 tops, and discharge assembly is installed on the static roller platen, and the spherical spring in the discharge assembly contacts (bearing insulation against ground) with static impression roller bearing; Discharge assembly links to each other with high pressure generator, high pressure generator produces high pressure, directly produce absorption voltage by discharge assembly at the bearing of static roller platen, pass to the glue-line surface of static roller platen, form a loop by stock 6 and gravure printing roller again, so just between static roller platen and gravure printing roller, form the static district of a high pressure.Under the effect of high pressure, transferred to the surface of stock in the version roller equably by free printing ink, make the rate of transform of printing ink almost reach 100%; Static is eliminated rod and is connected with high pressure generator, is installed in the front and back that stock enters the electrostatic pressure glue-printing roller, eliminates the static that accumulates on the stock.
Claims (2)
1. a static blotter comprises static roller platen, discharge assembly, high pressure generator, static elimination rod, gravure printing roller, and it is characterized in that: described high pressure generator is eliminated rod with discharge assembly and static respectively and is connected; Described discharge assembly is connected with the static roller platen; Described static roller platen is positioned at the top of gravure printing roller, and stock passes between static roller platen and gravure printing roller; Described static is eliminated rod two, is installed in the front and back position that stock enters the electrostatic pressure glue-printing roller respectively.
