Problems solved by technology
After stirring through the ink pump and the gravure, the iron powder will be brought into the concave part of the gravure. Under the force of the pressure rubber roller, the iron powder and ink will be transferred to the printed matter at the same time, which will cause the graphic part of the printed matter to be missing. Iron powder is applied to the ink. After the printed matter passes through the drying system, the iron powder falls off, resulting in unprinted graphics and texts, which leads to missing printing and a large amount of waste products, which increases the production difficulty of subsequent processes.

The invention discloses a gravure printing ink adsorption device which comprises a rotating roller. The rotating roller is connected with a transmission mechanism and rotatably arranged on a fixed seat, and the fixed seat is fixed to an ink cylinder. A left-handed screw groove is formed in the outer surface of one end of the rotating roller, a right-handed screw groove is formed in the outer surface of the other end of the rotating roller, and the axis of the rotating roller is parallel to the axis of a gravure plate. The gravure printing ink adsorption device is used for filtering iron powder generated by operation of a scraper on the gravure plate, so that the quality of printed matter is improved, and the rejection rate of the printed matter is lowered.
Description
technical field [0001] The invention relates to a gravure printing ink circulation system of a gravure printing machine, in particular to a gravure printing ink absorption device. Background technique [0002] In the prior art, the gravure printing machine is mainly composed of the following parts: a paper loading unit, a paper tension unit, a printing unit, a registration unit, a drying unit, a cutting unit, a delivery unit and the like. The quality and color of the printed product in the above units are mainly completed by the cooperation of the ink supply system and the gravure transfer system. The adhesion between the ink and the gravure determines the quality of the printed matter. The ink supply system is mainly through manual mixing of the ink, the transporter ink storage tank, the ink is delivered to the ink tank of the printing unit through the ink supply pump, and the ink soaks 2 / 3 of the gravure in the ink tank, and the movement of the transmission shaft Under f...
