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

The invention discloses an ink-pond ink distribution device for a photogravure press. The ink-pond ink distribution device comprises a compression roller (1), a printing roller (2), a doctor blade (3), an inking roller (4) and an ink pond (5). A grid plate (6) is arranged on the lower portion in the ink pond (5). The grid plate (6) divides the ink pond (5) into an inking area (7) and a stirring area (8). A stirring mechanism (9) is arranged on one side of the ink pond (5) and located in the stirring area (8). A lifting platform (10) is arranged at the bottom of the ink pond (5). The stirring mechanism (9) comprises a shaftless spiral stirring rod (11) which is provided with a plurality of stirring holes (12). A connecting shaft (13) is arranged at one end of the shaftless spiral stirring rod (11). One end of the connecting shaft (13) is connected with a motor (14) which is connected with a controller (15). The controller (15) is further connected with the lifting platform (10). A sealing connecting structure is located between the stirring mechanism (9) and the ink pond (5). The ink-pond ink distribution device has the characteristics that the stirring efficiency is high and ink is distributed very evenly.
Description
Technical field [0001] The present invention involves the field of printing machinery, especially a concave printing machine. Background technique [0002] The main structure of the gravure printing machine consists of five parts: paper, ink, printing, drying, and paper collection. Among them, the printing part is the main process. In the printing part, the ink roller is rotated in the ink pool to provide ink supply and ink supply and inkDue to the gravity effect of the ink in the ink pond, the uniformity of its own changes will change to varying degrees. Usually the lower ink is thicker than the upper ink, which causes the overall distribution of inks in the ink pool.Print quality.Therefore, the current concave printing machine has the problem that the ink distribution in the ink pond is not very uniform. Invention content [0003] The purpose of the present invention is to provide a uniform ink device for the concave printed machine with ink pool. It has the characteristics of...
