According to the arrangement, the two printing rollers are directly driven by the main driving shaft through the gears, and then the anilox rollers for printing the color group are directly driven by the printing rollers through the gears, so that the outer diameter of the printing rollers is greatly reduced compared with that of the printing rollers of the satellite type printer, the processing difficulty of the printing machine is reduced, the precision of the printing rollers after the processing is high, the manufacturing cost is greatly reduced, and the production and maintenance cost is low; because a sufficient space position is arranged between the two printing rollers for installing the drying device, the printing unit can be dried efficiently after printing of each color group, and the defect that the distance between the printing units of satellite printing is too short, ink is poor in drying and is easy to smear is avoided; the two printing rollers are directly driven by the same main driving shaft, and compared with a machine set type or laminated type complex transmission system, the two printing rollers are good in synchronism in rotation, simple in structure and short in transmission route, so that the transmission precision is high, and the printing quality of each color group is good; the first printing roller and the second printing roller are vertically arranged up and down, the occupied area is small, the short tension change of the idle line of the printing stock is small, and the control is easy; the compression roller compresses and bonds the printing stock on the printing roller through the air cylinder, and the pressure can be adjusted through the air cylinder, so that the bonding property of the printing stock and the printing roller is ensured, the self-adaptive adjustment according to the thickness of the printing stock can be realized, and the printing quality is ensured; the main driving shaft is driven by a servo motor, so that the on-line combination of the pre-printing and post-printing processes can be conveniently carried out.

The invention further provides that: the drying device 10 is a totally-enclosed drying box.

Through this setting, the totally closed stoving case heat loss is little energy-conserving effect obvious, and stoving temperature is stable to the stoving effectual of printing product, and drying efficiency is high, can adapt to high-speed printing production.

The invention further provides that: and a guide roller 9 is further arranged above the second printing roller 5 to guide the material to be printed 6.

Through this setting, the position is positive when the stock gets into and leaves the printing unit, and the business turn over material is smooth and easy, is favorable to improving print quality.

Compared with the prior art, the invention has the following beneficial effects:

the invention creatively provides a novel printer structure, overcomes the structural defects of the flexographic printing machine in the prior art, and has the advantages of simple transmission structure, low manufacturing and production and maintenance difficulties, low cost, good quality of printing products, high production efficiency, small occupied area, obvious energy-saving effect and easiness in carrying out pre-printing and post-printing process connection.
