Problems solved by technology

[0003] The main structure of the gravure printing machine consists of five parts: paper feeding, ink feeding, printing, drying, and paper delivery. The printing part is the main process. In the printing part, the ink roller is rotated in the ink pool to supply ink and Transmission, the uniformity of the ink in the ink pool will change to varying degrees due to gravity, usually the lower ink is thicker than the upper ink, which causes the overall distribution of the ink in the ink pool is not very uniform, which will affect printing quality; at the same time, when the existing ink scraping device scrapes off the excess ink on the ink roller, the distance between the ink scraping device and the ink roller cannot be effectively adjusted

Abstract

The invention discloses an inking device applied to a printing machine, which includes an impression cylinder and a printing plate cylinder, and also includes an air pump, a motor, and an ink storage tank. The ink storage tank includes a lower tank body and an upper tank body, and a stirring assembly is arranged on the inner bottom of the lower tank body The stirring assembly includes a stirring shaft, a first telescopic tube, several second telescopic tubes, a movable block, and several stirring plates. One side of the upper pool body is provided with a scraping assembly, and the scraping assembly includes a fixed plate, a first scraper and several The second scraper, the fixed plate horizontally penetrates into the upper pool body, the end surface of the fixed plate located in the direction of the upper pool body is also provided with a first square hole matching the first scraper, the first scraper is located in the first square hole, A second square hole is also provided in the first scraper. The invention can stir the ink stored in the ink storage pool, and can satisfy the needs of stirring inks of different depths in the ink pool, improve the stirring effect of the ink, and at the same time, use the ink scraping assembly to quickly adjust the amount of ink on the substrate.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to an inking device applied to a printing machine. Background technique [0002] Gravure printing is a printing method in which the inked part of the printing plate is concave. By applying ink to the concave graphic part of the printing plate, the excess ink is removed by a doctor blade or other methods, and then under the action of printing pressure, the ink is transferred to the substrate to complete the printing process. Gravure printing has clear layers, thick and bright ink layer, uniform ink color, can truly reproduce the effect of the original manuscript, and the printing speed is fast. It is one of the most widely used printing methods at present. [0003] The main structure of the gravure printing machine consists of five parts: paper feeding, ink feeding, printing, drying, and paper delivery. The printing part is the main process. In the printing part, the ink roller is ...
