Abstract

The high-speed single gravure printing machine specifically comprises a printing machine body, a gravure cylinder is arranged in the printing machine body, fixing frames are arranged at the two ends of the gravure cylinder, and the fixing frames are fixed to the inner wall of the printing machine body; the scraper device is arranged on the portion, located above the gravure cylinder, of the fixing frame, and mounting openings are formed in the side faces of the fixing frame and the printing machine body; the scraper device comprises a fixed tool apron, hydraulic telescopic rods are connected to the two ends of the top of the fixed tool apron through rotating seats, a fixed seat is fixedly connected to the tops of the hydraulic telescopic rods, and the center of the bottom of the fixed seat is connected with the fixed tool apron through a universal rotating device. According to the high-speed single gravure printing machine, the levelness of the scraper can be judged through the friction force between the scraper and the gravure cylinder, self-adaptive adjustment is carried out, judgment and recognition are more accurate, adjustment is more timely, and the machining efficiency of the device is higher.

Description

technical field [0001] The invention relates to the technical field of printing machines, in particular to a high-speed single-gravure printing machine. Background technique [0002] A printing press is a machine that prints text and images. Modern printing machines are generally composed of plate loading, ink application, embossing, paper feeding and other mechanisms. Its working principle is: first make the printing plate of the text and image to be printed, install it on the printing machine, and then apply the ink to the place where the text and image are on the printing plate manually or by the printing machine, and then transfer it directly or indirectly Printing on paper or other substrates, so as to reproduce the same printed matter as the printing plate, the invention and development of printing presses play an important role in the spread of human civilization and culture. After the gravure printing machine currently used is used for a long time, the doctor blade...
