Embodiment Construction

[0013] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0014] see figure 1 , a doctor blade for a printing machine according to a preferred embodiment of the present invention includes a knife seat 1 and a blade 2 arranged on the knife seat 1, the blade 2 and the knife seat 1 are fixed by screws 3, and the front and back sides of the blade 2 are provided with sponge4. The blade 2 is provided with three threaded holes 5 matched with the screws 3 . The blade 2 is made of stainless steel.

[0015] The present invention arranges sponge 4 on the front and back sides of the scraper. When there is too much ink, the ink will inevitably accumulate along the blade 2. At this time, the sponge 4 will absorb part of the ink to ensure th...

Abstract

The invention relates to a component of a printing machine, in particular to a scraper of a printing machine. The scraper of the printing machine comprises a knife holder and a blade arranged on the knife holder, the blade and the knife holder are fixed through a screw, sponges are arranged on the front surface and the reverse surface of the blade, when printing ink is excessive, the printing ink can be accumulated upwards along the blade necessarily, and at the moment, the sponges can absorb part of the printing ink so as to guarantee good scraping effect of the scraper.

Description

technical field [0001] The invention relates to a printing machine component, in particular to a printing machine scraper. Background technique [0002] As one of the four major printing methods today, gravure printing has been widely promoted and applied in the past ten years. Gravure printing is characterized by simple printing machine structure, high printing plate durability, fast printing speed, stable printing quality, thick printing ink color, rich layers, low cost when printing in large quantities, and is very competitive. [0003] The main components of the gravure printing machine are roller, pressure roller and scraper. The function of the scraper is to scrape off unnecessary ink from the printing plate, so that the ink with graphics and text can be clearly transferred to the printed material. [0004] However, in the process of scraping off the ink, sometimes there is too much ink, and the scraping of the scraper is not thorough enough, which will cause ink acc...
