Problems solved by technology

Gravure printing is printed by direct printing with circular pressure. The printing plate is directly made on the printing plate cylinder, and the ink is supplied by immersion or inkjet. The printing machine must supply ink evenly when it is running, especially for high-speed gravure printing machines. The job requirements are higher. When the existing printing machine is running, due to the flow control and ink supply defects, it is easy to cause uneven printing and affect the printing quality.

Abstract

The invention discloses a closed type ink feeding device used for a gravure printing machine. The closed type ink feeding device comprises an ink barrel, a motor and a three-way ball valve are installed above the ink barrel, and one side of the ball valve is sequentially connected with a first ink feeding pipe, a second ink feeding pipe, a spraying gun and an ink feeding device body. The closed type ink feeding device is provided with an ink supplying groove, a backflow pipe and a flowmeter. Ink is prevented from being thrown outside a plate while being supplied evenly, when surplus ink on the plate flows down, part of ink will be accumulated to soak the surface of a plate cylinder, the ink supplying situation is further improved, and the printing quality is improved.

Description

technical field [0001] The invention relates to a closed ink supply device. Background technique [0002] When printing on a gravure printing machine, the entire plate cylinder is inked, and the ink on the blank part of the plate is scraped off with a squeegee, leaving the ink on the graphic part, and then passed through the paper or pet film, and the impression cylinder is printed on the paper or pet. The back of the film is embossed, so that the ink in the concave part is directly transferred to the surface of the paper or PET film, and finally the printed matter is stacked or rewound through the delivery paper or the PET film. Gravure printing is printed by direct printing with circular pressure. The printing plate is directly made on the printing plate cylinder, and the ink is supplied by immersion or inkjet. The printing machine must supply ink evenly when it is running, especially for high-speed gravure printing machines. The requirements for this work are higher. Wh...
