Automatic Copy paper cut-size sheeting and ream wrapping Machine Tension Control System Application Scheme

Automatic Copy paper cut-size sheeting and ream wrapping Machine is a kind of mechanical equipment that cuts wide-width paper or film into multiple narrow-width materials, and is often used in papermaking machinery and printing and packaging machinery. Its transmission system is mainly composed of a host frequency converter, an unwinding frequency converter and two winding frequency converters. Among them, the host inverter works in the open-loop vector mode to control the speed of the system. The unwinding inverter and the two rewinding inverters work in the open-loop torque mode to control the system's unwinding and upper and lower rewinding after slitting.

Automatic Copy paper cut-size sheeting and ream wrapping Machine tension control system program description:

The host inverter uses Inovance general inverter MD500 to control the running speed of the slitting machine. It works in the open-loop vector mode. The main speed is generally adjusted with a potentiometer. Its AO1 port is used as the output of the running frequency and used as the unwinding. The line speed of the inverter and the upper and lower winding inverters is given.

The unwinding inverter and the rewinding inverter use Inovance MD330 special inverter for tension. All three inverters work in open-loop torque mode; Inovance MD330 inverter is a inverter that can realize constant tension control. The real-time coil diameter of the material coil can be obtained through the internal calculation of the inverter, and the constant tension control can be obtained by controlling the output torque of the inverter;

Advantages of Automatic Copy paper cut-size sheeting and ream wrapping Machine program:

The tension control system of Automatic Copy paper cut-size sheeting and ream wrapping Machine has a simple scheme and simple debugging, and the constant tension control is basically not affected by the speed, which can realize high-speed slitting;

Automatic Copy paper cut-size sheeting and ream wrapping Machine tension control system can make up for the starting or acceleration process caused by system inertia, friction resistance and material inertia by setting reasonable system inertia compensation, friction compensation and material inertia compensation related parameters In the case of uneven speed, a very smooth tension control effect is obtained.

Moreover, the rewinding inverter can realize taper control to achieve the effect of tight rewinding. It overcomes the inherent weakness of magnetic powder, makes the control of Automatic Copy paper cut-size sheeting and ream wrapping Machine a reality, and greatly improves the reliability of the equipment.
