Application Overview

Film slitting machine is a kind of equipment for slitting mother rolls with different widths, different lengths and different thicknesses into products of various specifications required by users. The precise control of the tension of the unwinding and unwinding is the key technology of the film slitting machine. It requires that the product after slitting and winding has no wrinkles, no scratches, neat end faces, and appropriate hardness of the winding surface.

Application requirements

  • Rewinding and unwinding motors with encoders, requiring inverters with PG closed-loop operation

  • The PLC outputs the given tension signal, and the position of the swing lever is used for tension feedback. The inverter is required to have a closed-loop tension control function

  • High and low speed tension is constant, the speed is stable, and the swing of the swing rod is small

  • Satisfy the system quick start and stop, emergency stop requirements

  • The inverter has built-in standard communication function, which is convenient for PLC monitoring

1、Overview of MV600T inverter

MV600T is a special tension control frequency converter developed by Megmeet Drive Technology Co., Ltd. It can automatically control the output torque or automatically adjust the speed of the controlled traction machine, so that the tension on the belt (wire) material is kept constant, suitable for papermaking , Paper processing, printing and dyeing, packaging, wire and cable, adhesive tape, textile, leather, metal foil processing, fiber, rubber and other industries. For the control of winding and unwinding, the inverter's internal winding diameter calculation module can automatically calculate the change in the diameter of the reel, making the tension control more accurate. Using the MV600T inverter can completely replace the torque motor, DC motor, tension controller, etc. to form a tension control system independently. Compared with the traditional tension controller plus inverter control scheme, using this inverter can make the system more concise and reduce costs, Easy to maintain and obtain more stable control effect.

  2、System solution

Through the touch screen, the user can set the parameters such as working speed, running tension, roll diameter, etc. At the same time, the current operating status of the device can be displayed, and the current fault information can be displayed for further processing by the user.

The PLC coordinates the actions of the peripheral equipment, and controls the operation of the equipment according to the process set by the user to make the tension setting and frequency setting for the inverter.

This system uses the MV600T tension control special frequency converter for winding and unwinding control, which can ensure constant tension and stable speed during the operation of the equipment. It is the core part of the control of the entire system.
