Problems solved by technology

[0003] However, the working printing angle of the existing printing mechanism used in gravure printing machines is relatively fixed, and it is impossible to quickly adjust the operation according to the thickness of the actual printing material. At the same time, when the excess ink is scraped, ink dripping and waste are prone to occur. , leading to more ink usage, which in turn increases the operating cost of the printing mechanism

Abstract

The invention discloses an adjustable printing mechanism used for a gravure press. The adjustable printing mechanism comprises an installation frame, servo motors, an ink transmission roller, a firstink scraper and a second ink scraper. The overlook section layer of the installation frame is of an inverted-U-shaped structure. The ink transmission roller is rotationally connected to the outer edgepositions of the inner surface walls of the horizontal ends of the two sides of the installation frame. The number of the servo motors is two, and the two servo motors are fixed to the outer surfacewalls of the horizontal end of one side of the installation frame through bolts. The two servo motors are in transmission connection with the first ink scraper and the second ink scraper through couplers. The first ink scraper is located above the second ink scraper. In the adjustable printing mechanism, the printing mechanism can be used for reducing the waste amount of ink, surplus ink on the surface of the ink transmission roller is also removed, meanwhile, adjusting operation of the working height and the printing pressure of the ink transmission roller can also be achieved, and the printing quality is further improved.

Description

technical field [0001] The invention relates to the technical field of printing equipment, in particular to an adjustable printing mechanism for a gravure printing machine. Background technique [0002] When printing on a gravure printing machine, the entire plate cylinder is inked, and the ink on the blank part of the plate is scraped off with a squeegee, leaving the ink on the graphic part, and then passed through the paper, and the impression cylinder is pressed on the back of the paper. The ink in the concave part is directly transferred to the paper surface, and finally the printed matter is stacked or rewound through the delivery part, so the printing mechanism has become the most important component of the gravure printing machine [0003] However, the working printing angle of the existing printing mechanism used in gravure printing machines is relatively fixed, and it is impossible to quickly adjust the operation according to the thickness of the actual printing mat...
