Flexographic Printing Press (Servo Motor Control)
This flexographic printing press is driven by servo motor for its transmission part. And the registration function is also implemented by servo motor simultaneously, thus featuring rapid printing speed and high printing accuracy.
We have two standard types of fully servo-driven flexographic printing presses for you to choose from. Besides, we are capable to offer custom-engineered flexo printing press for adapting to your preferences.

1. The unwind unit has double shafts which are driven by dual-motor, it facilitates operation and saves both material and time.
2. Three pneumatic cylinders are used for web splicing, with closed loop dancer tension control.
3. Designed with functions of initiative unwinding by inverter motor, automatic measuring of the roll diameter, adhesive detecting, etc.
1. The rewind unit has double shafts which are driven by dual-motor. Alarm will be activated when presets are reached, and operator is informed to quick change rolls.
2. By using closed loop dancer roll tension control and equipping with nip roll, the consistency of web tension can be maintained, enabling an optimal roll surface.
1. The infeed nip unit consists of a steel roller and a rubber roller for web pulling. And it designed with edge position control for web guiding.
2. Steel nip roller is driven by an independent servo motor having a variable speed drive, which is used in measuring the tension of web by dancer roll potentiometer, and used in closed loop tension control by PLC terminal.
3. Rubber nip roller is pneumatically activated with dual pneumatic cylinders, with self-locking function.
1. As a satellite printing unit, central impression cylinder is imported from Italia, with Siemens direct driven motor, ensuring high transmission accuracy.
2. Caliper disc brake is used for timely braking under high speed running with high safety.
3. Printing plate is designed in an integrated structure featuring high rigidity and hard to deformation, and using print sleeve for fast plate mounting.
4. Ink is scraped by chambered doctor blade with ceramic anilox roll, this allows high efficiency of ink scraping and greatly reduces ink volatilization and environmental pollution, facilitating quick wash up and shortening ink refill time and machine idle time.
1. Drying tunnel is designed with external bearing and guide roller.
2. Drying hood is pneumatically opened and closed. With a design of negative pressure inside the drying tunnel, hot air can be prevented from escaping, thus achieving automatic control of internal temperature.
Ink viscosity control—This unit aims at automatically measuring and regulating of ink and solvent, facilitating follow-up operations.
Printing plate mounting machine—This machine can be used when printing substrates are soft, it helps reducing machine tension which generates pulling force on substrates.
European brand doctor blade—Chambered doctor blades from European brands have excellent air humidity resistance, avoiding blade being corroded.
Corona treater—This corona treatment unit increases the adhesion of substrate surfaces.
