Problems solved by technology
[0002] 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. The supply and transmission of ink is carried out by the inking roller rotating in the ink pool. Due to the action of gravity, the uniformity of the ink in the ink pool will change to varying degrees. Usually, the lower ink is thicker than the upper ink, so The overall distribution of the ink in the ink pool is not very uniform, which will affect the printing quality
Therefore, the current gravure printing machine has the problem that the ink distribution in the ink pool is not very uniform

Description
technical field [0001] The invention relates to the field of printing machinery, in particular to an ink pool and ink distribution device for a gravure printing machine. Background technique [0002] 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 print quality. Therefore, the current gravure printing machine has the problem that the ink distribution in the ink pool is not very uniform. Contents of the invention [0003] The object of the present invention is to provide a device for distributing ink in an ...
