Abstract
The invention discloses a gravure press printing device, which comprises a plate cylinder and an impression cylinder. A printing material is driven by a first driving roller and a second driving roller to be impressed by the plate cylinder and the impression cylinder, and an ink duct is positioned under the plate cylinder; a doctor is positioned at one side of the plate cylinder, and the included angle between the blade of the doctor and the tangent of the plate cylinder is between 30 degrees and 60 degrees; the thickness of a gap between the surfaces of the plate cylinder and the impression cylinder and the thickness of the printing material are equal, and the surface of the impression cylinder is coated with a rubber layer. The doctor is reasonably designed, and the included angle between the blade and the tangent of the plate cylinder is between 30 degrees and 60 degrees, so that the good ink transfer can be realized, and thus the printing quality is ensured, and the rejection rate of printed products is reduced.
Description
Technical field
The invention belongs to printing machinery technical field, relate to a kind of printing equipment, be specifically related to gravure printing machine brush device.
Background technology
Intaglio press is transferred to the ink of the picture and text part on plate cylinder on stock by squeegee pressure, it has plurality of advantages simple in structure, that press resistance rate is high, print speed printing speed is fast, print quality is good, and is applicable to the printing of lock carton, flexible package and facing paper.Intaglio press is divided into sheet-fed and web-fed gravure press by paper feeding mode, by printable fabric, is divided into paper and plastic sheeting intaglio printing press, by printing chromatic number, is divided into monochrome, double-colored and multicolour rotogravure press.Intaglio press comprises charging gear, the inking device, printing equipment, material collecting device and drying device critical piece.
The printing equipment of intaglio press comprises standard type and top nip drum cartridge type printing equipment, and the former is comprised of plate cylinder and impression cylinder.Wherein, plate cylinder is cylindrical shape, and copper coating, as plate, then, by engraving or photoetching, forms sunk picture and text at cylinder surface.The plate cylinder of intaglio press directly immerses in ink tank, ink under running up fills up plate cylinder soon, then through doctor, the ink of forme surface blank parts is scraped off, the ink of remaining picture and text groove part, roll extrusion through impression cylinder is transferred to ink on paper or other stock, becomes printed matter.
Printing machine is under regular service conditions, and existing ink knife arranges unreasonable, causes inking inhomogeneous, not only wastes ink, and has affected printing quality.
Summary of the invention
The object of this invention is to provide the gravure printing machine brush device that a kind of simple in structure, ink shifts evenly, can guarantee print quality.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is as follows:
Gravure printing machine brush device, comprise plate cylinder and impression cylinder, printable fabric impresses through the gap between described plate cylinder and impression cylinder under the drive of the first live-roller and the second live-roller, ink fountain be positioned at described plate cylinder under, doctor is positioned at a side of plate cylinder, the angle of the blade of described doctor and described plate cylinder tangent line is 30～60 °, described plate cylinder equates with the thickness of printable fabric with the gap between impression cylinder surface, and the surface of described impression cylinder is surrounded by rubber layer.
As improvement of the present invention, the thickness of above-mentioned impression cylinder surface rubber layer is 12～15mm.
Compared with prior art, the beneficial effect that the present invention has is:
Doctor of the present invention is reasonable in design, can on doctor blade, spray sodium rice metal level, thereby has greatly extended the service life of scraper, has reduced the replacing number of times of scraper, has reduced printing cost; The angle of blade and plate cylinder tangent line is 30～60 °, can realize good ink and shift, and has guaranteed printing quality, has reduced the percent defective of printing.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the structural representation of gravure printing machine brush device of the present invention.
The specific embodiment
As shown in Figure 1, gravure printing machine brush device, comprise plate cylinder 3 and impression cylinder 4, printable fabric impresses through the gap of 4 of described plate cylinder 3 and impression cylinders under the drive of the first live-roller 6 and the second live-roller 5, ink fountain 1 be positioned at described plate cylinder 3 under, doctor 2 is positioned at a side of plate cylinder 3, the angle of the blade of described doctor 2 and described plate cylinder 3 tangent lines is 30～60 °, described plate cylinder 3 equates with the thickness of printable fabric with the gap between impression cylinder 4 surfaces, and the surface of described impression cylinder 4 is surrounded by rubber layer.The thickness of described impression cylinder 4 surface rubber layers is 12～15mm.
The present invention is when operation, and impression cylinder 4 surfaces are provided with rubber layer, and printable fabric pressurized is evenly mild, can guarantee the printing quality of printable fabric, and the blade of doctor 2 is 30～60 ° with the angle of stating plate cylinder 3 tangent lines; Can realize good ink and shift, guarantee printing quality; When spray sodium rice metal level (as spraying sodium rice tungsten carbide metal layer) on doctor blade, can greatly extend the service life of scraper, reduce the replacing number of times of scraper, thereby reduce printing cost.
By reference to the accompanying drawings the present invention is exemplarily described above; obviously specific implementation of the present invention is not subject to the restrictions described above; as long as the various improvement that Bian has used method design of the present invention and technical scheme to carry out; or directly apply to other occasion without improvement, all within protection scope of the present invention.
