Abstract
The utility model discloses a gravure printing-ink scraping device of a gravure printing machine. The gravure printing-ink scraping device comprises a sleeve and end covers fixed at two ends of the sleeve, circular supporting frames are evenly and axially installed in the sleeve, the outer circumferential surface of each supporting frame is provided with a groove, a permanent magnet is installed inside each groove, the shapes of the permanent magnet are matched with those of the grooves, and a spiral colloidal body is installed on the outer circumferential surface of the sleeve. When the gravure printing-ink scraping device rolls in a printing ink groove, the permanent magnets keep that the spiral colloidal body of the outer circumferential surface of the sleeve makes contact with the surface of a gravure plate. When the spiral colloidal body rolls, the spiral colloidal body serves as a plain milling cutter to work, and bubbles on the surface of the gravure plate are scraped into gap channels on two sides of the spiral colloidal body and discharged. Besides, the hardness of the spiral colloidal body is lower than that of the gravure plate, so that the spiral colloidal body cannot scrape the gravure plate when making contact with the gravure plate. Therefore, the bubbles are prevented from being attached to the gravure plate, and meanwhile printing quality is improved.
Description
Technical field
The utility model relates to intaglio printing press production line servicing unit, especially a kind of intaglio printing press intaglio plate ink scraping apparatus.
Background technology
Intaglio printing is a kind of as typography, and, advantages such as saturation degree high, forme press resistance rate height, print quality stable, print speed printing speed fast real, bright-colored with its printing product China ink bed thickness occupy extremely important status in printing packaging and picture and text publishing area.The intaglio printing press production line of China is mainly introduced overseas equipment, when the intaglio printing press cylinder rotates in the printing ink high speed, thereby a large amount of bubbles have been produced, these bubbles depend on the intaglio plate, doctor blade also can't be removed it fully, and the doctor misoperation also causes scuffing to intaglio plate, if the bubble accumulation for a long time, make the printing finished product produce the flower version, cause a large amount of printed matters to scrap.
As from the foregoing, above-mentioned existing intaglio printing press printing equipment obviously has defective and exists, and remains to be improved.
Summary of the invention
At the deficiencies in the prior art, the utility model aims to provide a kind of intaglio printing press intaglio plate ink scraping apparatus, guarantees in printing process, and printing ink produces bubble and can't depend on the intaglio plate, improves printing quality.
For solving the problems of the technologies described above, the technical solution adopted in the utility model: a kind of intaglio printing press intaglio plate ink scraping apparatus, comprise sleeve pipe and the end cap that is fixed in the sleeve pipe two ends, the annular bearing support axially evenly is set in sleeve pipe, the outer circumference surface of bearing support is provided with groove, permanent magnet is installed in groove, and the shape and the groove of permanent magnet are complementary, and are provided with the helical form gel at the outer circumference surface of sleeve pipe.
With said apparatus in ink tank intaglio printing press cylinder front, owing in sleeve pipe, be provided with permanent magnet, this device is in ink tank in the rolling process like this, permanent magnet keeps the helical form gel of sleeve pipe outer circumference surface to contact with the intaglio plate surface, in the helical form gel rotation process, it is the same to be equivalent to plain milling cutter work, the clearance channel that the bubble on intaglio plate surface is blown into shape gel both sides is discharged, and gel hardness is lower than intaglio plate, when gel contacts with intaglio plate, can not scratch intaglio plate, stop bubble like this and depended on the intaglio plate.
The utility model test of many times is effectively stopped the bubbles of ink on the intaglio plate, has improved the intaglio printing press printing quality.
Description of drawings
Fig. 1 is the utility model structural representation;
In the accompanying drawing: 1 sleeve pipe, 2 end caps, 3 permanent magnets, 4 bearing supports, 5 gels, 6 clearance channel.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, sleeve pipe 1 adopts tube and pipe of aluminium alloy to be processed into, be fixed with end cap 2 at sleeve pipe 1 two ends, one end of end cap 2 and sleeve pipe 1 endoporus are interference fit, end cap 2 adopts nylon material to make, end cap 2 is sealed at both ends with sleeve pipe 1, annular bearing support 4 axially evenly is set in sleeve pipe 1, annular bearing support 4 adopts nylon material to make, the outer circumference surface of bearing support 4 is provided with groove, and groove integral body also is annular, and permanent magnet 3 is installed in groove, for the ease of mounting permanent magnet 3, permanent magnet 3 is processed into the subdivision body; Outer circumference surface at sleeve pipe 1 is provided with helical form gel 5, and promptly cross section is that square gel 5 spirals are around in sleeve pipe 1 outer surface; Axial at sleeve pipe 1, space between the adjacent gel 5 forms clearance channel 6, when the intaglio printing press cylinder is worked, because cylinder makes printing ink produce bubble in the rotation of ink tank high speed, these bubbles depend on the intaglio plate, and the helical form gel 5 of sleeve pipe 1 outer surface can scrape the bubble on the intaglio plate, drives away from clearance channel 6, thereby has guaranteed the finished product printing quality of intaglio printing press.
