Description

Intaglio printing press

Technical Field

The utility model relates to a printing machine, more specifically say, it relates to an intaglio printing machine.

Background

When a gravure printing machine prints, the full plate surface of a printing plate roller is inked, ink on the blank part of the plate surface is scraped off by a doctor blade, ink on the image-text part is left, then paper is fed, the back of the paper is impressed by an impressing roller, the ink on the concave part is directly transferred to the paper surface, and finally, a printed product is piled or rewound by a paper collecting part. Friction between the printing plate roller and the impression roller during printing generates a large amount of heat, and the heat can cause ink on the printing plate roller to dry too fast during printing, so that printing waste is large. This is particularly evident when printing metallic inks.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a when the printing, avoid printing plate roller and impression roller high temperature and lead to the dry intaglio press of printing ink.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides an intaglio press, includes china ink groove, printing plate roller, embossing roller and ink scraping knife, the both ends of printing plate roller and embossing roller all rotate through the axle sleeve and connect, the both ends of printing plate roller and embossing roller distribute along the circumferencial direction has a plurality of ventilation hole, still erects air cooling support on the axle sleeve at printing plate roller both ends, air cooling support's tip extends to embossing roller department, the last ventilation hole department that corresponds printing plate roller and embossing roller of air cooling support all is provided with the mounting hole, all be provided with blowing nozzle in the mounting hole, blowing nozzle has the refrigeration fan through the pipe connection.

The utility model discloses further set up to: and two ends of the printing plate roller and two ends of the stamping roller are also provided with wind blocking rings.

The utility model discloses further set up to: the connection mode of the air blowing nozzle and the mounting hole is threaded connection.

The utility model discloses further set up to: the side wall of the shaft sleeve is provided with a mounting groove, the air cooling support is clamped in the mounting groove, and one end of the shaft sleeve is provided with a fastening bolt for fastening the air cooling support.

Through adopting above-mentioned technical scheme, this practical printing machine can cool off version roller and impression roller when printing, prevents that these heats can lead to the printing ink drying on the version roller too fast at the in-process of printing to cause the printing waste product many.

Detailed Description

Embodiments of the present invention are further described with reference to fig. 1 to 3.

The utility model discloses an intaglio press, including china ink groove 1, printing plate roller 2, embossing roller 3 and ink scraping knife 4, printing plate roller 2 and embossing roller 3's both ends are all rotated through axle sleeve 5 and are connected, printing plate roller 2 and embossing roller 3's both ends distribute along the circumferencial direction has a plurality of ventilation hole 6, still erect air cooling support 7 on the axle sleeve 5 at printing plate roller 2 both ends, the tip of air cooling support 7 extends to embossing roller 3 department, ventilation hole 6 department that corresponds printing plate roller 2 and embossing roller 3 on the air cooling support 7 all is provided with mounting hole 70, all be provided with blowing nozzle 71 in the mounting hole 70, blowing nozzle 71 has cooling fan 8 through the pipe connection. And two ends of the printing plate roller 2 and the two ends of the stamping roller 3 are also provided with wind-blocking rings 9. The blowing nozzle 71 is connected with the mounting hole 70 in a threaded manner. The side wall of the shaft sleeve 5 is provided with a mounting groove 50, the air cooling support 7 is clamped in the mounting groove 50, and one end of the shaft sleeve 5 is provided with a fastening bolt for fastening the air cooling support 7.

The working principle is as follows: when the printing machine prints, the refrigerating fan 8 is turned on, the air blowing nozzles 71 blow out cold air, and the positions of the two air blowing nozzles 71 are arranged corresponding to the air vents 6 of the printing plate roller 2 and the stamping roller 3, so that the air blowing nozzles 71 continuously blow cold air towards the air vents 6 in the rotating process of the printing plate roller 2 and the stamping roller 3, the printing plate roller 2 and the stamping roller 3 can be cooled, and the phenomenon that printing ink on the printing plate roller 2 is dried too fast due to heat generated in the printing process of the printing plate roller 2 and the stamping roller 3 is prevented, so that printing waste is caused to be excessive.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection.
