Abstract
The utility model relates to a gravure colour printing machine ink transfer device, comprising an ink duct containing printing ink and a printing cylinder. The surface of the printing cylinder is above the liquid of the printing ink. The utility model is provided with a feed roller driven by power. The surface of the lower part of the feed roller is submerged in the printing ink and the surface of the upper part is above the liquid of the printing ink. The surface of the upper part of the feed roller is close to or contacted with the surface of the printing cylinder; the shaft of the feed roller is parallel to the shaft of the printing cylinder; the rotation direction of the feed roller is opposite to the rotation direction of the printing cylinder; the liner velocity of the feed roller is 1/5 to 1/4 of the liner velocity of the printing cylinder. The utility model is additionally provided with a feed roller whose rotation brings the printing ink out of the ink duct to the printing cylinder to print. The printing cylinder does not directly contact with the printing ink in the ink duct. As the liner velocity of the feed roller can be 1/5 to 1/4 of the liner velocity of the printing cylinder, the restriction on the liner velocity of the printing cylinder is greatly decreased, the phenomenon of ink splashing during high-speed printing is avoided, and the printing ink waste, the increase in the cost and abnormal operation of the machine caused by ink splashing are avoided.
Description
Technical field
The utility model relates to the intaglio plate chromatic printing machine, specifically, relates to a kind of intaglio plate chromatic printing machine printing ink transfer device.
Background technology
The inking device of existing intaglio plate chromatic printing machine comprises the ink tank and the plate cylinder that fill printing ink, and the plate cylinder direct part is immersed in the ink tank, and when plate cylinder rotated, its surface printing ink, prints then.This structure can be used in low speed printing fashion, but when print speed printing speed is that the linear velocity of plate cylinder is during greater than 100 meters/minute, leave printing ink liquid level place at plate cylinder and black phenomenon will occur spattering, the plate cylinder linear velocity is big more, it is serious more to spatter China ink, this not only wastes printing ink, increases production cost, also can cause printing equipment normally not move when serious.
Summary of the invention
For remedying the deficiencies in the prior art, the intaglio plate chromatic printing machine printing ink transfer device that is fit to high speed printing is provided, the utility model proposes a kind of intaglio plate chromatic printing machine printing ink transfer device, its technical scheme is as follows:
A kind of intaglio plate chromatic printing machine printing ink transfer device comprises the ink tank and the plate cylinder that fill printing ink, and it is characterized in that: the plate cylinder surface is higher than the printing ink liquid level; Be provided with one by power-actuated fountain roller, this fountain roller lower surface is immersed in the printing ink, upper face is higher than the printing ink liquid level, its upper face is pressed close to mutually with the plate cylinder surface or is contacted, and its axle with plate cylinder is parallel, the direction of rotation of its rotation direction and plate cylinder.
Above-mentioned fountain roller can be a rubber rollers.
Above-mentioned fountain roller linear velocity preferably the plate cylinder linear velocity 1/5～1/4.
The diameter of above-mentioned fountain roller can be 80～120 millimeters, and the degree of depth that is immersed in the printing ink approximately is 15～30 millimeters.
The utility model sets up one by power-actuated fountain roller between printing ink and plate cylinder, fountain roller is rotated printing ink is taken up and transfer to plate cylinder printing from ink tank, plate cylinder not with ink tank in printing ink directly contact.Because the fountain roller linear velocity can be 1/5～1/4 of a plate cylinder linear velocity, when the plate cylinder linear velocity was 100 meters/minute, the fountain roller linear velocity can be 25 meters/minute; When the plate cylinder linear velocity reaches 400 meters/minute, the fountain roller linear velocity still can be arranged on below 100 meters/minute, this reduces the suffered restriction of plate cylinder linear velocity greatly, occur when avoiding high speed printing spattering black phenomenon, thereby avoid that printing ink waste, cost that China ink causes increase and the irregular operating of machine owing to spattering.In addition, because fountain roller is different with the plate cylinder linear velocity, fountain roller is close on the plate cylinder again, has certain pressure so can make between fountain roller and the plate cylinder, thereby makes the printing ink coating weight more even.
Description of drawings
Accompanying drawing is the structural representation of the utility model one embodiment.
The specific embodiment
Intaglio plate chromatic printing machine printing ink transfer device as shown in drawings, comprise the ink tank 2 and the surperficial plate cylinder 3 that is higher than printing ink 1 liquid level that fill printing ink 1, and one by power-actuated fountain roller 4, these fountain roller 4 lower surface are immersed in the printing ink 1, upper face is higher than printing ink 1 liquid level, its upper face contacts with plate cylinder 3 surfaces, its axle with plate cylinder 3 is parallel, and the direction of rotation of its rotation direction and plate cylinder 3, linear velocity are 1/5 of plate cylinder 3 linear velocities.
Above-mentioned fountain roller 4 is rubber rollers, and its diameter is 100 millimeters, and the degree of depth that is partially immersed in the printing ink is 20 millimeters.
When fountain roller 4 is rotated under power drive, the surface go up printing ink 1, again printing ink 1 is transferred to plate cylinder 3, plate cylinder 3 not with ink tank 2 in printing ink 1 directly contact, because fountain roller 4 linear velocities are 1/5 of plate cylinder 3 linear velocities,, it is 80 meters/minute for the linear velocity of film roller 4 even be the linear velocity of plate cylinder 3 when reaching 400 meters/minute in print speed printing speed, be lower than 100 meters/minute, leave printing ink 1 liquid level place in fountain roller 4 and still can not spatter black phenomenon.Because fountain roller 4 is different with plate cylinder 3 linear velocities, fountain roller 4 is close to again on the plate cylinder 3, has certain pressure so can make between fountain roller 4 and the plate cylinder 3, thereby makes printing ink 1 coating weight more even.
