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 ink feeding device. The closed ink feeding device is used for gravure printing machines and comprises an ink barrel. A motor and a three-way ball valve are mounted above the ink barrel. One side of the ball valve is sequentially connected with a first ink inlet pipe, a second ink inlet pipe, a spray gun and an ink feeder. The closed ink feeding device provided by the invention is provided with an ink supply tank, a backflow pipe and a flowmeter, and printing ink is prevented from being thrown to the outside of a forme when the ink is uniformly supplied. When surplus printing ink on the forme flows down, part of the printing ink is accumulated so that the surface of a plate cylinder can be soaked in the printing ink, the ink supply condition is further improved, and the printing quality is improved.

Description

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