Cutting machine is a large roll of paper, film, non-woven fabrics, aluminum foil, mica tape, etc. Various kinds of thin material cutting into different width smaller volume before printing, post-press equipment, often used in paper making machinery and printing and packaging machinery.

Before cutting machine of magnetic powder clutch speed can not high, because of the magnetic powder at runtime high-speed friction, produce high temperature, shorten its life, serious stuck, when they make the machine run, have serious consequences for production.


Heavy impact on production efficiency. Now, the dual-frequency converter motor is adopted to control the magnetic powder friction at a certain value under the condition that the diameter of the winding material becomes larger. There's no heat.

Traditional control scheme of the cutting machine is the use of a large rolling shaft, motor to drive on and scroll with magnetic powder clutch, by adjusting the current of magnetic powder clutch to control the resistance, to control the tension of the material surface. Magnetic powder clutch and brake is a special kind of automation equipment, it is work by filling the gap magnetic powder transmission torque, changed the magnetic current can change the state of magnetic powder, and then adjust the transmission of torque. It can be used for stepless speed regulation from zero to synchronous speed. It is suitable for speed regulation system with fine tuning of high speed section and small power. It is also used to adjust torque by adjusting current to ensure the uncoiling or rewinding tension control system with constant tension during winding.

The cutting machine is constantly changing from single motor control to double motor, and the development of three motors makes the machine more stable and efficient under the condition of faster machine speed.

The main characteristic of the slitting machine is that magnetic powder clutch, as a resistance device, can output a dc voltage through the system control to control the resistance of magnetic powder clutch. The main advantage is that it is passive and can control less tension.

Disadvantages: the speed can't be high, and it is easy to cause high speed friction of magnetic powder when running at high speed, resulting in high temperature, resulting in heating of magnetic powder clutch and shortening its life. A device for cutting lengthwise sections of a material of a certain width with a cutter and cutting several narrow strips into sections. After installing it in calender, extruder, gluing machine and other unit devices, it can complete continuous cutting, often with winding device. Cutting knife can be used flat blade knife and round mouth knife.

Paper products processing machinery series of products: paper disk cutting machine, small disk paper cutting machine, drum paper cutting machine, high speed cutting machine

Metal cutting machines: strip cutting machines, copper sheet cutting machines, aluminum sheet cutting machines, stainless steel cutting machines, tinplate cutting machines, etc.

Tension control

The magnetic powder brake device of the cutting machine is divided into the winding group of the cutting machine, which is connected with the pneumatic expansion shaft by the drive part. The speed of winding is controlled by controlling the torque of the magnetic powder brake

Rewinding magnetic powder brake

Rewinding magnetic powder brake

Degrees. Magnetic powder brake is selected according to the size of the whole coil material in the coiling group of the cutting machine. The common specifications of magnetic powder brake of the cutting machine are 12Nm, 25Nm, 50NM, 100Nm, 200Nm and 400Nm. Cutting machine magnetic powder brake is mainly to provide balanced and stable torque, can cooperate tension controller to adjust the torque, the rolling work of cutting machine and the whole efficiency, enhance its quality.

Magnetic powder brake tension control precision, simple and convenient, can prevent the cutting machine put volume group materials and cutting machine magnetic powder brake used DC24V dc voltage, heat dissipation optional natural cooling fan for cooling (air) or device. When installing, please keep the magnetic powder brake of the cutting machine on the horizontal axis and the surrounding environment not too wet.

Equipment features: 1. Centralized panel operation, integrated circuit control. All parts of the machine focus on panel operation control. 2. Main functions of the panel: a. spindle speed adjustment b. winding length setting c. winding tension adjustment d. winding tension setting e. starting. Stop button. 3. The cutting tool is round up and down. The cutting width can be changed according to different cutting width, and the cutting width can be adjusted to achieve high quality cutting quality.

Using the environment

The machine should be installed in a place with proper temperature, dry, ventilated, good light and convenient operation.
