Abstract

The invention belongs to the technical field of ink supply devices with scrapers, and particularly discloses a printing ink removal device. The printing ink removal device comprises an ink removal cutter. A wedge face is arranged at one end of the ink removal cutter. A cavity is formed in the ink removal cutter, and a spraying part and a recycling part are arranged in the cavity. A cleaning part is further arranged on the lower end face of the ink removal cutter. The spraying part comprises a liquid storage box, a liquid conveying pipe, spraying holes formed in the wedge face, and a drive mechanism. The liquid storage box communicates with the liquid conveying pipe. A liquid inlet is formed in the side wall of the liquid storage box, and the other end of the liquid conveying pipe communicates with the spraying holes. The recycling part comprises a backflow hole formed in the wedge face and located below the spraying holes, and baffles fixed to the two side walls of the ink removal cutter. The spraying holes communicate with the liquid storage box, and a quantitative backflow mechanism is arranged in the backflow hole. The cleaning part comprises a supporting frame and a cleaning roller, wherein the supporting frame is fixedly connected with the lower end face of the ink removal cutter, the cleaning roller is rotationally connected with the supporting frame, and a cleaning layeris arranged on the cleaning roller. According to the purpose, the problem that after an existing printing roller makes contact with paper, a small amount of ink is left on the surface is solved.

Description

technical field [0001] The invention belongs to the technical field of ink supply devices with scrapers, and specifically discloses a printing ink removal device. Background technique [0002] Printed matter is very common in daily life. Whether it is various books and newspapers or clothing and slogans, they are all products obtained through printing. [0003] At present, when printing on paper products, the paper to be printed is usually conveyed through the conveying roller group, and then the ink is printed on the surface of the paper through the printing roller. The ink in the ink tank is evenly coated on the printing cylinder, and then the excess ink is scraped off by the scraper to avoid uneven ink coating on the surface of the printing cylinder, which will affect the printing quality. [0004] However, after the printing roller prints the ink onto the surface of the paper, there will be a small amount of ink remaining on the printing roller, and the remaining small ...
