Problems solved by technology

[0002] When the printing machine is printing, the ink is scraped on the roller. When the printed material passes through the printing roller, the ink on the roller will be printed on the material. Generally, the ink is scraped on the roller directly through the scraper. Squeegee coating is carried out on the roller with the rotation of the roller, but the ink on the scraper is not evenly distributed, which will cause uneven ink distribution on the roller. When printing, some places are printed clearly, while some places are printed blurred, affecting D

Abstract

The invention discloses an ink scraping drive device which comprises a motor. The motor is connected with a first connecting rod through a gear. The first connecting rod and a second connecting rod are connected through an eccentric bearing. The second connecting rod and a third connecting rod are perpendicular to each other. The third connecting rod is connected with a fourth connecting rod on an ink scraping piece. The motor is connected with a PLC for controlling the rotating speed of the motor. The motor drives the first connecting rod to rotate. Due to the effect of the eccentric bearing, the second connecting rod drives the third connecting rod to move left and right. In the left and right moving process, the ink scraping piece enables ink on the ink scraping piece to be distributed evenly, and therefore a roller can be evenly coated with the ink in the ink scraping process.

Description

technical field [0001] The invention relates to an ink scraping driving device, which belongs to the technical field of printing machinery. Background technique [0002] When the printing machine is printing, the ink is scraped on the roller. When the printed material passes through the printing roller, the ink on the roller will be printed on the material. Generally, the ink is scraped on the roller directly through the scraper. Squeegee coating is carried out on the roller with the rotation of the roller, but the ink on the scraper is not evenly distributed, which will cause uneven ink distribution on the roller. When printing, some places are printed clearly, while some places are printed blurred, affecting D. Contents of the invention [0003] The invention relates to an ink scraping driving device, which can make the ink scrape and coat on the roller more uniformly. [0004] To achieve this goal, the structure adopted in the present invention is: a scraping ink driv...
