Packaging machine manufacturers share how to understand the application of slitter.

Only a better understanding of the application of the slitter can make the slitter bring better cost performance in the society. Let's introduce the application of the slitter to you.

The slitter is a pre press and post press equipment that cuts a large roll of pearl cotton, paper, film material, non-woven material, and various thin materials such as aluminum foil material and mica tape into small rolls of different width, which is commonly used in paper-making machinery, printing industry and packaging industry.

In the past, the speed of the magnetic powder clutch of the slitter can not be too high, because it is easy to cause high-speed friction of the magnetic powder during operation, and it is easy to generate high temperature, shorten its service life, and it will be stuck when it is serious, which will block the operation of the machine and bring serious consequences to production.

It seriously affects the efficiency of production. Now it is updated to double frequency conversion motor to control, so that the magnetic powder friction can be controlled at a certain value by frequency conversion motor when the diameter of winding material becomes larger. Without high temperature. High speed Slitter

The conventional control scheme of the slitter is to use a large motor to drive the winding shaft. A magnetic powder clutch can be added to the winding shaft. The resistance produced by the magnetic powder clutch can be controlled by adjusting the current of the magnetic powder clutch to control the tension of the material surface. Magnetic powder clutch and brake is a kind of special automatic actuator. It transfers torque through magnetic powder filled in the working gap. Changing the magnetic current can change the magnetic state of magnetic powder, and then adjust the transmitted torque. It can be used for stepless speed regulation from zero to synchronous speed, suitable for high-speed section fine-tuning and small and medium power speed regulation system. It is also used to adjust the torque by adjusting the current to ensure that the tension in the winding process remains constant.
