PRINTING AND SETTING
Newest registration technology – Camera based model registration
Automatic registration for printing stations (Paper running direction & operation direction)
Auto register for paper running direction can be controlled on both printing section and touch screen
Auto register for operation direction can be controlled on both printing section and touch screen
360°Auto-register function, to guarantee stable register during printing. The automatic registration controller can adjust the Phrase Position of the servo motor according to the detected error, realizing the quick registration and improving the operating quality and the extent of automation, so the machine greatly reduces the labor intensity and the attrition rate of raw materials. This operation is completed when the machine is in registration condition.
Operation direction’s registration can be realized by moving plate cylinder
Plate pressure & printing pressure area adjustment will be displayed on screen
PRE-REGISTER
Before running the machine, plate cylinder tries to find correct position by itself (position is calculated by machine computer). Lower down paper waste, achieve faster job setup.
DRYING SYSTEM
Hot Air and IR
Each of the printing units is equipped separately and adopts the high-power IR light tube
I.R short-wave heating and drying system and temperature is adjustable
Warm air and natural air-drying system including exhaust fan and blower with adjustable volume
Equipped with hot air fan to make sure the drying quality
Collect the waste gas and release it through the exhaust fan
IR power can be controlled separately and automatically according to the printing speed
Single printing section temperature control is available, better adapt to different printing materials and reduce the energy consumption of the whole machine
OUT-FEED TENSION CONTROL
Tension roller is driven by servo motor, the outfeed tension is controlled by servo motor to ensure the stable tension
Specified with pressure glue roller to clutch and feed and to guarantee the stable tension
1 servo motors
1 servo driven
1 high precision gearboxes
