Problems solved by technology

[0002] In the existing printing machines, it is generally necessary to set up a scraper to scrape off the excess ink on the plate roller; however, due to reasons such as improper installation or wear and tear, the scraper is tilted or partially worn, which in turn leads to a batch reduction in printing quality
Especially when it is used for a long time and partially worn, the scraper is usually replaced directly, resulting in higher maintenance costs
Therefore, the scraper in the existing printing machine has the problems that the printing quality is easy to reduce and the maintenance cost is high when it is used.

Abstract

The invention discloses a high-precision adjusting device for a printing machine scraper. The high-precision adjusting device comprises a bottom plate and a stand; the stand is provided with two first guide rails, each of the first guide rails is provided with two first slide blocks, each of the first slide blocks is hinged with a connecting rod, and the top end of the connecting rod is connected with a hinged seat; a fixed plate is arranged above the bottom plate, a rotating shaft is connected between the bottom plate and the fixed plate, a lower connecting plate is arranged above the bottom plate, and an upper connecting plate is arranged below the fixed plate; a second slide block is connected below the lower connecting plate, and the bottom plate is provided with a second guide rail connected with the second slide block; and a scraper is connected between the bottom plate and the fixed plate. Scraper inclination and local wear of the scraper can be compensated by adjusting the scraper, and the high-precision adjusting device not only can be used for improving the printing quality, but also has the advantages of low maintenance cost, high adjusting precision, good compensation effect and convenience in installation and fixation.

Description

technical field [0001] The invention relates to a doctor blade adjustment device for a printing machine, in particular to a high-precision doctor blade adjustment device for a printing machine. Background technique [0002] In existing printing machines, it is generally necessary to set up a scraper to scrape off excess ink on the plate roller; however, due to reasons such as improper installation or use wear, the scraper is tilted or partially worn, which in turn leads to a batch reduction in printing quality. Especially when the use time is long and the part is worn out, the scraper is generally replaced directly now, resulting in higher maintenance costs. Therefore, the scraper in the existing printing machine has the problems of easy reduction of printing quality and high maintenance cost during use. Contents of the invention [0003] The object of the present invention is to provide a high-precision doctor blade adjustment device for a printing machine. The inventio...
