Printing machine scraper multi-directional adjustment device

Abstract

The invention discloses a multi-directional adjustment device of a printing press scraper. The multi-directional adjustment device of a printing press scraper comprises a base plate, wherein one connecting plate is arranged at the bottom of each of the two ends of the base plate, a double-screw bolt is arranged on each connecting plate, through holes are formed in the positions, corresponding to the double-screw bolts, of the base plate, a machine base is arranged below the connecting plates, two guide rails symmetrical to each other are arranged on the machine base in parallel, a first sliding block is arranged at the bottom of each guide rail, guide grooves connected with the sliding blocks are formed in the machine base, two second sliding blocks are connected with the top of each guide rail, each second sliding block is hinged to a connecting rod, one hinge joint base located on the bottom surface of each connecting plate is connected with the top end of each connecting rod, a fixed plate is arranged above the base plate, and a rotating shaft and a scraper are arranged between the base plate and the fixed plate. According to the multi-directional adjustment device of a printing press scraper, inclination and partial abrasion of the scraper can be compensated by adjusting the scraper in multiple directions, it can be avoided that the quality of printing is lowered, and the multi-directional adjustment device of a printing press scraper further has the advantages of being low in maintenance cost, convenient to use, assemble and disassemble, and good in stability of installation and fixation.

Description

technical field [0001] The invention relates to a doctor blade adjustment device for a printing machine, in particular to a multidirectional adjustment device for the doctor blade of 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 multi-directional adjustment device for a doctor blade of a printing machi...

AI Technical Summary

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.
