Problems solved by technology
The working principle of the gravure printing machine is that the printing plate roller is soaked in the ink tank. After the plate roller rotates up, the scraper scrapes off the excess ink on the surface of the printing plate, and then presses the paper on the printing plate roller through the embossing roller to make the gravure The ink on the incoming graphic is transferred to the paper to complete the printing, but the original gravure printing machine squeegee lock may cause the squeegee to tilt during long-term use, causing batch problems in printing quality. It will be difficult to solve the phenomenon of squeegee tilting

The invention relates to the technical field of printing machines, in particular to a gravure press ink scraping blade adjusting device. An ink scraping blade is fixedly connected with a fixing seat through two fixing screws. The fixing seat is provided with a fixing seat hinge opening. A cutter rest is provided with a cutter rest hinge opening. The fixing seat and the cutter rest are hinged to the cutter rest hinge opening in the mode that a hinge shaft penetrates through the fixing seat hinge opening. First balance bolts penetrate through two first bolt holes correspondingly. Two second balance bolts penetrate through two second bolt holes correspondingly. The fixing seat is hinged to a base through a first hinge shaft. The lower end of a cylinder is fixedly connected with the upper surface of the base. When the gravure press ink scraping blade adjusting device is used, through the adjustment of the cylinder and rough adjustment of the position of the cutter rest, the position of the ink scraping blade is adjusted, and on the other hand, through fine adjustment of the two first balance bolts, the gap between a blade and an anilox roller is adjusted, and thus the printing quality of can be improved effectively. When abrasion occurs to the ink scraping blade, the position of the blade can be readjusted through the cylinder, and thus waste due to blade replacement is reduced. In addition, the gravure press ink scraping blade adjusting device is simple in structure, reasonable in design and low in manufacturing cost.
Description
technical field [0001] The invention relates to the technical field of printing machines, in particular to a doctor blade adjustment device for gravure printing machines. Background technique [0002] Gravure printing machine is the most important printing equipment in cigarette label printing enterprises. Gravure printing machine is the abbreviation of gravure printing machine. Gravure printing refers to the printing method in which text and images are lower than the surface of the printing plate. The working principle of the gravure printing machine is that the printing plate roller is soaked in the ink tank. After the plate roller rotates up, the scraper scrapes off the excess ink on the surface of the printing plate, and then presses the paper on the printing plate roller through the embossing roller to make the gravure The ink on the incoming graphics is transferred to the paper to complete the printing, but the original gravure printing machine squeegee lock may caus...
