Inking device applied to printer

Abstract

The invention discloses an inking device applied to a printer. The inking device comprises an impression cylinder and a plate cylinder, and further comprises an air pump, a motor and an ink storage pool; the ink storage pool comprises a lower pool body and an upper pool body; a stirring assembly is arranged at the inner bottom of the lower pool body; the stirring assembly comprises a stirring shaft, a first telescopic pipe, a plurality of second telescopic pipes, a movable block and a plurality of stirring plates; an ink scraping assembly is arranged on one side of the upper pool body and comprises a fixing plate, a first scraping plate and a plurality of second scraping plates; the fixing plate horizontally penetrates through the upper pool body; a first square hole matched with the firstscraping plate is further formed in the end face, located in the direction of the upper pool body, of the fixing plate; the first scraping plate is located in the first square hole; and second squareholes are further formed in the first scraping plate. According to the inking device applied to the printer, printing ink stored in the ink storage pool can be stirred, the requirement for stirring the printing ink of different depths in the ink storage pool can be met, the stirring effect of the printing ink is improved, and meanwhile the ink feeding amount of a printing stock can be rapidly adjusted through the ink scraping assembly.

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 ...

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
