Description

Gravure press

Technical Field

The utility model relates to a lithography apparatus field especially relates to an intaglio printing machine.

Background

The intaglio printing press transfers the ink of the image-text part on the printing plate cylinder to the printing stock by means of printing pressure, has the advantages of simple structure, high printing resistance, high printing speed and good printing quality, and is suitable for printing folding paper boxes, flexible packages and decorative paper. The intaglio printing press is classified into a sheet-fed and web-fed intaglio printing press according to the paper feeding mode, a sheet-fed and plastic film intaglio printing press according to the printing material, and a monochromatic, bicolor and multicolor intaglio printing press according to the printing color number. The gravure printing machine comprises a feeding device, an inking device, a printing device, a receiving device and a drying device.

The printing unit of the intaglio printing press comprises a standard type and a top-pressure cylinder type printing unit, the former consisting of a plate cylinder and an impression cylinder. The printing plate cylinder is cylindrical, the surface of the printing plate cylinder is plated with copper as a plate material, and then concave pictures and texts are formed on the surface of the printing plate cylinder through engraving or photo corrosion. The plate cylinder of the gravure press is directly immersed into the ink tank, the ink running at high speed quickly fills the plate cylinder, then the ink on the blank part of the plate surface is scraped off by the doctor blade, the ink on the groove part of the image-text is left, and the ink is transferred to paper or other printing stocks by the rolling of the impression cylinder, thus forming the printed matter.

An intaglio printing press is generally provided with an ink transfer roller for transferring ink in an ink tank to a plate cylinder, and the prior art ink transfer roller is not provided with a heating device inside, so that when the ink adheres to the surface of the ink transfer roller, the ink cannot be sufficiently transferred to the plate cylinder due to the low temperature of the ink, the viscosity increase, the poor fluidity, and the poor transferability, resulting in printing accidents.

The ink fountain top among the prior art is open to set up and its inside agitating unit that does not set up, and the mobility of printing ink is very poor, and printing ink solidifies easily, and the surface of printing ink exposes in the air completely moreover, and printing ink can lead to printing plate cylinder surface irregularity because oxidation reaction, dry too fast and mobility difference form one deck "printing ink skin" when "printing ink skin" attaches to on the printing plate cylinder, leads to the printed matter to appear polluting, the printing accident appears.

The utility model provides an intaglio press, including the china ink groove, china ink groove upper portion both sides respectively set up an apron, and two apron clearances set up, and wherein the apron below of one side sets up the distributor roller, sets up the plate cylinder between two apron, and the bottom height that the bottom of distributor roller is less than the bottom height of plate cylinder, the inside oil pipeline that sets up of distributor roller, oil pipeline set up oil inlet and oil-out respectively in the both sides end shaft department of distributor roller, the china ink inslot sets up at least one stirring roller, the stirring roller includes interconnect's roller and stirring roller end shaft, sets up biax gear motor in the roller, and stirring leaf is indulged to biax gear motor's output shaft, and every indulges the rigid coupling has at least one violently to stir the leaf on the stirring leaf.

Furthermore, an ink inlet pipe is arranged at the upper part of one side of the ink tank, and an ink outlet pipe is arranged at the lower part of the other side of the ink tank.

Further, a doctor blade is arranged on the upper portion of one side of the plate cylinder.

Further, the cover plate is hinged with the side wall of the ink groove.

Further, the cover plate is detachably arranged.

Further, the number of the stirring rollers is two.

Furthermore, four transverse stirring blades are fixedly connected to each longitudinal stirring blade, and the transverse stirring blades are symmetrically arranged relative to the longitudinal stirring blades.

The utility model discloses following beneficial effect has:

1. because set up oil pipeline and set up oil inlet and oil-out respectively in the both sides end shaft department of distributor roller in distributor roller, so can heat distributor roller through the conduction oil, guarantee distributor roller surface temperature, increase the mobility and the transferability of printing ink, reduce the viscidity of printing ink, guarantee that printing ink can the capacity transfer to the plate cylinder on, avoid the emergence of printing accident.

2. Because the upper portion at the china ink groove has set up detachable and china ink groove lateral wall articulated apron and has set up the stirring roller in china ink groove inside, so can reduce the evaporation oxidation and the solidification rate of printing ink, avoid the production of printing ink skin, guarantee the normal clear of printing.

Detailed Description

As shown in fig. 1, 2 and 3, an intaglio printing press, including the china ink groove 1, china ink groove 1 upper portion both sides respectively set up a apron 11, and two apron 11 clearance settings, the apron 11 below of one side sets up ink transfer roller 3, set up plate cylinder 2 between two apron 11, and the bottom height of ink transfer roller 3 is less than plate cylinder 2's bottom height, the inside oil pipeline 33 that sets up of ink transfer roller 3, oil pipeline 33 set up oil inlet 31 and oil-out 32 respectively in the both sides end shaft department of ink transfer roller 3, set up at least one stirring roller 4 in the china ink groove 1, stirring roller 4 includes interconnect's roller 41 and stirring roller end shaft 42, sets up biax gear motor 43 in the roller 41, and the output shaft of biax gear motor 43 indulges stirring leaf 44, the rigid coupling has at least one horizontal stirring leaf 45 on every indulging stirring leaf 44.

An ink inlet pipe 12 is arranged at the upper part of one side of the ink tank 1, and an ink outlet pipe 13 is arranged at the lower part of the other side of the ink tank.
