The main structure of gravure printing machine

The main structure of a gravure printing machine consists of five parts: paper feeding, ink feeding, printing, drying, and paper receiving.

1、The paper feeding part, sheet-fed gravure printing machine is a continuous feeding of paper in a stack, and web gravure printing machine is a continuous feeding of paper in a web.

2、In the printing part, the arrangement of the printing plate cylinder and impression cylinder is vertical, horizontal and inclined, and the printing plate cylinder is arranged at the bottom. Generally, each unit has 1 plate cylinder and 1 impression cylinder. In order to increase the printing pressure, some are equipped with 2 impression cylinders.

3, gravure printing press inking device has the plate cylinder partly immersed in the ink tank of the direct inking and by immersed in the ink tank of the ink roller will be inked to the plate cylinder indirect inking, some high-speed machines also use the inkjet method.

4, the drying part of the gravure printing machine is the use of electricity or steam heated hot air, some infrared or far-infrared lamps to dry the printed material.

5, the receiving part of the paper, sheet-fed paper is stacked into a paper pile, web paper is cut and folded paper tape stacked or rewound into a paper roll. The structure of the printing part of the web multi-color gravure printing machine has 2 types of unit type and satellite type. The former is set up according to the required number of colors, each unit has 1 plate cylinder and 1 to 2 impression cylinders, and the paper receiving part is rewound. The satellite type four-color gravure printing machine has one large impression cylinder and four sets of plate cylinders in the printing part. There is also a combination of gravure printing with lithographic printing or letterpress printing, die-cutting, etc., to meet the different requirements of printed materials.
