Abstract
The invention discloses an ink scraping device for an offset printing proofing machine. The device consists of a cutting tool, wherein the cutting tool consists of a cutter bit and a fixed body; the cutter bit is connected to the front end of the fixed body and consists of a solid elastic body; a blade part is arranged at the front end of the cutter bit and consists of two intersecting oblique surfaces; one oblique surface has the height of 1mm and the width of 0.5mm, and the cutter bit has the height of 5mm; the cutter bit consists of a solid elastic body such as rubber, has high elasticity and can be used for applying higher pressure onto an ink scraping cutter, so that the cutter bit can be tightly contacted with the surface of an ink distributing roller, more printing ink can be scraped off, and an ink scraping cutter bit and the ink distributing roller cannot be damaged; and an oblique angle of which the width is 0.5mm and the height is 1mm is formed on the head part of the ink scraping cutter, and an oblique surface which can be tightly attached to the surface of the ink distributing roller is formed on the ink scraping cutter bit, so that an ink scraping effect is improved.
Description
Technical field:
The present invention relates to mechanical field, relate in particular to printing machinery, particularly offset proofing press, concrete is a kind of device for ink of scraping that is used for offset proofing press.
Background technology:
Offset proofing press can only carry out drawing a design of a color at every turn, changes when drawing a design color and must earlier the residual ink in black groove and the ink roller be removed totally, could add new printing ink then.Offset proofing press strikes off residual ink on the wavers by the device for ink of scraping that is installed in other one of wavers and is similar to blade shapes, and the material of scraping device for ink is the PVA material.When carrying out wiping work, regulate position and the pressure of scraping device for ink, it is contacted with the wavers surface, rotate wavers simultaneously, finish the work of removing residual ink.But scraping device for ink is the PVA material, and quality is harder, can not be close to the wavers surface, the wiping cutter head in the wiping process and the contact area between the wavers less, wiping is abundant inadequately, need expend the long period and the printing ink on wavers surface could be removed clean.In addition, it is harder to scrape the device for ink material, contacts the back for a long time with the metal wavers and is worn than being easier to, and causes doctor blunt in front, the wiping deleterious.
Summary of the invention:
The object of the present invention is to provide a kind of device for ink of scraping that is used for offset proofing press, described this scraping device for ink and will solving prior art and scrape device for ink and the wavers contact area is little, the wiping amount is little, easy to wear technical problem of offset proofing press that be used for.
This device for ink of scraping that is used for offset proofing press of the present invention, constitute by a cutter, wherein, described cutter is made of cutter head and fixed body, described cutter head is connected the front end of fixed body, cutter head is made of solid elastomer, and the front end of cutter head is provided with blade, and blade is made of two crossing inclined-planes.
Further, the height on a described inclined-plane is 1mm, and wide is 0.5mm.
Further, the height of described cutter head is 5mm.
Operation principle of the present invention is: cutter head is by solid elastomer, and for example rubber constitutes, have better elastic, can apply bigger pressure, it is closely contacted with the wavers surface doctor, scrape more printing ink, and can not cause damage wiping cutter head and wavers; At the doctor head, make a wide 0.5mm, the oblique angle of high 1mm becomes an inclined-plane that itself and wavers surface can be fitted tightly at the doctor capitiform.
The present invention and prior art are compared, and its effect is actively with tangible.The present invention scrapes the solid elastomer of employing in the device for ink as cutter head offset proofing press, can fully contact with wavers, once can scrape more printing ink, increases work efficiency; The cutter head front end is provided with a little inclined-plane, and cutter and wavers surface can be fitted tightly, and improves the wiping effect.
Description of drawings:
Fig. 1 is a kind of structural representation of scraping device for ink that is used for offset proofing press of the present invention.
Fig. 2 is a kind of schematic perspective view of scraping device for ink that is used for offset proofing press of the present invention.
The specific embodiment:
Embodiment 1:
As depicted in figs. 1 and 2, a kind of device for ink of scraping that is used for offset proofing press of the present invention, constitute by a cutter, wherein, described cutter is made of cutter head 1 and fixed body 2, and described cutter head 1 is connected the front end of fixed body 2, and cutter head 1 is made of solid elastomer, the front end of cutter head is provided with blade, and blade is made of the inclined-plane 3 and the inclined-plane 4 that intersect.
Further, the height on inclined-plane 4 is 1mm, and wide is 0.5mm.
Further, the height of described cutter head is 5mm.
Claims (3)
