Wide range of tension adjustment, easy to operate, convenient, compact system, reliable operation and simple maintenance.

We provide:

 1.New rotogravure press equip four sectors of floating rollers tension control

2.Old rotogravure press re-equip four sectors of floating rollers tension control.

3. Old rotogravure press update to four sectors of floating rollers tension control.

 

Application:

Kinds of tension controller widely used in gravure printing press, coating & laminating equipment, paper making equipment, complex equipment, high control precision,

Features:

1. Dancer arm tension control system, the tension can adjust through cylinder pressure, the location of the dancer arm is detected by the optical encoder;

2. Every Micro Servo control unit is independent control, noninterference in each other, and management by the center computer;

3. The tension can keep reliable, smooth during, cutting film, jointing film ,and  speed up, speed down.

4. System parameters easy modify, intuitive, and operate;

5. The digital transmission, good anti-jamming capability, accurate measurement.

6. Real-time monitoring machine operating state, input and output conditions;

7. Real-time display error of tension, torque, motor speed, the dancer arm position error and variety curve;

8. Achieve a true digital detection, optical encoder and no damage mechanical part, long life;

9. Ultra-low friction air cylinder can be sensitive and sensing tension small changes.
