Description

Scraper clamp

Technical Field

The utility model belongs to the technical field of lithography apparatus, concretely relates to scraper anchor clamps.

Background

The scraper is a thin sheet used for scraping redundant ink on the surface of a roller on a printing machine and is divided into a metal type and a nonmetal type. The removal of the ink in the non-patterned areas is a key issue in every printing process, the ink doctor blade must have wear resistance and high efficiency to ensure high quality printing and it must be compatible with the long-lasting and high speed requirements of modern gravure printing.

Due to the increase of the demand of high-speed gravure printing machines in the market at present, machines of a plurality of printing plants need to continuously operate, the abrasion resistance of the blade is particularly important, but the scraper made of good materials is also abraded, the scraper needs to be replaced at the moment, the replacement period of the blade in the prior art is short, the replacement process is complicated, the operation of the machines and the improvement of the yield are seriously influenced, and the slow operation efficiency is low.

The Chinese patent with the application number of CN201920423047.7 discloses a scraper of a printing machine roller, which comprises a roller (1) and a knife rest (2) and is characterized in that the knife rest (2) comprises a bottom plate (3) and a scraper clamp (4), the scraper clamp (4) is cylindrical, a mounting groove (5) is formed in the surface of the scraper clamp (4), a blade (6) is arranged in the mounting groove (5), first threaded holes (7) are formed in the two sides of the blade (6), fixed blocks (8) are fixedly connected to the side surfaces of the two sides of the mounting groove (5) and located on the scraper clamp (4), second threaded holes (9) matched with the first threaded holes (7) are formed in the middle of the fixed blocks (8), the blade (6) and the fixed blocks (8) are fixedly connected through first bolts (11), a long shaft (10) penetrates through the middle of the scraper clamp (4), the number of the mounting grooves (5) is four, and the mounting grooves are uniformly and symmetrically distributed on the surface of the scraper clamp (4). When the blade is worn and replaced every time, different operators can repeatedly rotate to the worn blade due to the fact that the rotation direction is not limited, or under the condition that the blades on the scraper clamp are worn, the unknown operators still do rotation adjustment, time is delayed, and work efficiency is affected.
