The slitting machine is a large sheet of paper, film, non-woven fabric, aluminum foil, mica tape and other thin materials into different width of small volumes of prepress, Postpress equipment, commonly used in papermaking machinery and printing and packaging machinery.
The speed of magnetic particle clutch of the slitter is not high, because it can cause high speed friction and high temperature and shorten the service life of the magnetic powder during operation, which will block the machine seriously and cause the machine running blocked, which will bring serious consequences to the production.
Heavy impact on production efficiency. The dual variable frequency motor is used to control the friction of the magnetic powder under the control of the variable frequency motor. There is no high temperature.
The traditional control scheme of the slitter is to use a large motor to drive the shaft of the retractable coil. The magnetic particle clutch is added to the retractable reel, and the resistance produced by controlling the current of the magnetic particle clutch is controlled to control the tension on the surface of the material. Magnetic particle clutch and brake is a special automatic executive element. It transfers torque through magnetic powder filled in the working gap, changing the magnetic current, changing the magnetic state of magnetic powder, and adjusting the torque transferred. It can be used for stepless speed regulation from zero start to synchronous speed, and it is suitable for speed regulation system of high speed section and small and medium power. It is also used to adjust the torque by adjusting the current to ensure the unwinding or rewinding tension control system that keeps the tension constant during the winding process.
The cutting machine is constantly controlled from single motor to double motor, and the three motor is developed. It is more stable and efficient in the condition of faster machine speed.The main characteristic of the slitter is the magnetic particle clutch as a resistance device. Through the system control, a DC voltage is output to control the resistance produced by the magnetic particle clutch. The main advantage is that it is a passive device that can control smaller tension.
Shortcomings: the speed can not be high, high speed running easy to cause high speed friction of magnetic powder, produce high temperature, cause magnetic powder clutch heating and shorten its life. The tool used to roll a certain width of the longitudinal cutting section, cut device for a number of narrow segments. After being installed in a calender or a extruder or a coating machine, the continuous cutting strip can be completed, often with a winding device. Slitting knife knife and circular knife available flat sheet.
