All units are stationary .There is no need to move the printing unit when changing the printing plate so that the quality of overprinting can be guaranteed
Each unit of the machine is independently drive by “Rexroth ” Servo motor which is made in Germany .it has the high precision since there is no accumulated error of gears’ gap
The machine uses intelligent control and management .It can set and store multi parameter .All the function are clear on the humanized operating interface
The adjusting system is precise so that we can get a good effect when adjusting the pressure of linking and printing
The whole machine adopt an enclosed structure combined with induced draft fans outside ,which can guarantee the cleanness of internal machine as well as the precision of cardboard feeding and printing
Conveyor belts are used to increase the distance between printing units while no more induced draft fans is added in order to have the good printing quality and energy conservation

It is independently driven by servo motor ,having a long service life since there is no wear and tear of gear box . It also has the function of long-travel feeding
The induce draft fans can effective remove the dust of internal machine and the dust on the surface of cardboard together with brush to improve the printing quality
It is convenient to adjust the location of side/ front guides and the gap between feeding rollers by PLC

The printing unit is independently driven by servo motor .It has a simple mechanical structure which is easy to be maintained and can reduce the transmission error caused by mechanical wear
The unites are stationary .The distance between printing units is larger than that of traditional machines in order to avoid the influence of mechanical shocks and to extend the time of link absorption to have a good printing quality
Enclosed double doctor blade combined with ceramic anilox roller ,can distribute the ink enenly .It can improve the effect of printing dots of single color and multi colorprinting
The pneumatic diaphragm pumps are used to supply the ink .There are two inlets and two outlets in each pump which can save the ink and have a greater efficiency .The inking system is automatic circulated and will warm when lacking ink
The printing roller has the function of skew emendation to the printing plate ,which makes the hanging operation convenient
By inputting data on the human-computer ,we can have it automatic to adjust the gap between anilox roller and pressing roller as well as the location of printing roller in the direction of the breadth
The infrared drying system can be equipped as an option with each printing unit to improve the quality and speed of multicolor printing
