The gravure printing machine is one of the printing processes, and it is called the four printing methods together with lithography, letterpress printing, and screen printing. Gravure printing is a direct printing method. The groove on the printing plate is printed text and pattern. When printing, the ink is filled in the groove, and the excess ink on the printing plate (the ink on the non-printing surface) is scraped. The ink knife is scraped, and then the printing plate is pressed by the embossing roller to press the ink from the concave surface of the printing plate onto the printed matter to achieve the purpose of printing. This article will introduce you to the gravure printing machine manufacturer.
The gravure press blade should be placed at an appropriate height. The blade should be adjusted according to the printing speed. The printing speed is fast, the distance from the embossing point is far, the printing speed is slow, and the embossing point is closer.
The tension control of the unwinding tension zone of the gravure printing press is mainly performed by the uncoiler. Tension control is a main function of the uncoiler, so the control principle of the tension zone is consistent with the working principle of the uncoiler. The clutch, tension roller and tension controller form a closed-loop control system.
During the printing process, the paper is not easy to be separated, the paper on the delivery table is not properly received, or the paper on the paper feeding table is skewed and the overprinting is not allowed, etc., which may be caused by static electricity. To eliminate printing static electricity, a static eliminator is generally installed on the printing machine to ionize the air around the printing machine, thereby neutralizing the positive and negative static electricity on the paper. It is also possible to spray an appropriate amount of water mist around the gravure printing machine or behind the impression cylinder to remove static electricity from the paper. In addition, increasing the humidity in the printing shop is conducive to the elimination of static electricity.
On the gravure printing machine, the VE series inverter that can be used for constant tension control introduced by Delta is used, and the control of the motor by the inverter can automatically achieve the purpose of constant tension of the printing machine. The whole application has the characteristics of convenient adjustment and high cost performance.
