2. All units are stationary, independently driven by "Rexroth" Servo motor which is made in Germany, It has the high precision since there is no accumulated error of gears' gap.
"Rexroth" Servo motors
3. Can easily add any unit for upgrade more color.
4. There is no need to move the printing unit when changing the printing plate so that the quality of overprinting can be guaranteed.
5. All the machine uses intelligent control and management. It can set and store multi parameter.1000 carton phase and size can be store in the machine. full automatic adjustment, All the functions 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 inking and printing.
6. The whole machine adopts 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.
5. Timing conveyor belts are used to increase the distance between printing units, induced draft fan is added in order to have the good printing quality and energy conservation. We can also upgrade with top infrared ray dryers installation.
6. Bearing adopt the famous brand like HRB and NSK.
7. All the PLC adopt "Seimens" brand, the contactor adopt "SEIMENS" brand. the touch screen adopt Taiwan "DELTA" brand.
8. the Doctor blade is double closed type doctor blade, Auclear brand.
9. Ceramic roller adopt PRAXAIR brand from America.
10. All the servo motor and servo control system is Rexroth brand from original Germany.

1. Cardboard feeding unit.
.It is independently driven by "Rexroth" Servo motor made in Germany to carry out the lead edge feeding, having a long service life since there is no wear and tear of gear box. It also has the function of long-travel feeding. Extend feeding with servo motor, can decrease the feeding pressure to protect the corrugate hardness.
.With destaticizing device, fans and multi brush, can effectively remove the dust on the surface of cardboard to improve the printing quality.
.It is convenient to adjust the location of side/front guides and the gap between feeding rollers by PLC and touch screen.
2. The printing Unit and coating unit.
. Servo motor drive each unit,so has a simple mechanical structure which is easy to be maintained and can reduce the transmission error caused by mechanical wear.
. The units 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 ink absorption to have a good printing quality.
. Enclosed double doctor blades combined with ceramic roller, can distribute the ink evenly. It can improve the effect of printing dots of single color and the effect of multi color overprinting.
. The double direction 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 warn when lacking ink. The printing roller has the function of skew emendation to the printing plate, which makes the hanging operation of printing plate convenient.
. By inputting data on the human-computer interface(colorful touch screen), we can have it automatic to adjust the gap between ceramic 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.(need additional price)
. The printing roller material is cast steel, with easy adjustment device in the roller, while the printing plate fix not balance in four corner, no need take off the printing plate, can be adjust by printing roller and save the time.
3. The drying and conveying unit.(for ink dryer)
. This unit is independently driven by servo motor. It has a simple mechanical structure which can reduce the transmission error caused by mechanical wear.
. The conveying distance is enlarged to dry the ink and avoid scratch printing. The breadth of infrared drying system can be adjusted according to the size of cardboard and the power can be adjusted according to the feeding speed to save the energy.
The drying unit
. timing belt and vacuum transmission the corrugate board.
.with infrared ray dryer arrangement on the top of timing belt.used fo water base oil dryer.
. Dryer power can be adjust the capacity accord the speed and coating area.
4.The electric control system
The centralized control of electric system can automatic control the units of feeding, printing, coating and conveying. Each unit of the machine is independently driven by "Rexroth" Servo motor which is made in Germany to carry out the operation of feeding, printing and oil coating etc. of cardboard. The centralized control of German "Rexroth" Servo motor is combined with IO expansion and sensor inspection of each unit, which can control and inspect the distance between the units and warn. The operation interface of upper computer can centralized control and store the parameter of orders in each unit. With function of human-computer interaction, the operator can adjust the speed, production quantity, the gap and the location by inputting parameters. Each unit is equipped with human-computer interface, with which we can adjust the parameter of gap and location of this unit.
