Patent Application No. 8
Abstract: A cartoner printing unit includes a movable machine table, a printing roller supporting the rotation of the machine bed, and an impression roller located on the opposite side of the printing roller. To print and transport cardboard. In this case, the embossing roller is housed in a notched housing which is located on the side of the paperboard that enters the embossing roller so that the embossing roller is cleaned directly from the gap when the embossing roller is contaminated with ink. A vacuum chamber is defined adjacent to the side of the paperboard leaving the imprinting roller. Above the vacuum chamber, several rows of conveying wheels are supported on the same plane as the imprinting roller. Under the vacuum chamber, a vacuum is used to create a vacuum in the vacuum chamber to make the printing roller and the imprinting machine. The cardboard delivered by the rollers is transported to the next station on the conveyor wheel. The utility model overcomes the shortcomings of the prior art and can directly clean the ink on the surface of the impression roller from the outside without disassembling the relevant parts of the printing unit, thereby improving the work efficiency.
