What Are The Working Principles Of Slitting Rewinders

1. Cut the whole roll or the whole raw material in sections by the rewinder to a fixed length, such as plastic packaging materials, packaging cartons, steel plates, films, leather, cutting wood chips, and cutting control.

2. The slitting length can be set continuously, if the actual length of the cutting error, it is convenient to set the calibration method of the parameters.

3. The slitting control of the slitter rewinder is divided into static and dynamic cutting: the set length reaches a precise stop, then static cutting, cutting and restarting; within the set arrival time, in the dynamic dynamic cutting process Do not stop the cutting signal problem, the slitting machine in the material.


Structural advantages of slitting rewinder:
The front end of the main shaft is fixed on the base with a set of bearings, and the pulley is installed in the middle of a set of bearings; the compression cylinder is installed near the base, and the cylinder is supported by the cylinder. A set of support rod bearings is installed at the upper end of the rod to support the main shaft.

A plurality of blades are arranged on the upper end of the slitting rewinder, and arranged on the plurality of blades with a certain gap; the support of the main tool shaft is erected on the top of the slitting rewinder, in the cylinder in the middle of the installation.

The structural advantages of the slitter rewinder fill the gap of the automatic pipe cutting machine.

Slitting machine is a kind of mechanical equipment that cuts wide-width paper or film into multiple narrow-width materials. It is often used in paper-making machinery and printing and packaging machinery. The traditional control scheme of the slitting machine is to use a large motor to drive the rewinding and unwinding shaft. A magnetic powder clutch is added to the rewinding and rewinding shaft. The resistance generated by the magnetic powder clutch is controlled by adjusting the current of the magnetic powder clutch to control the surface tension of the material. . Magnetic powder clutch and magnetic powder brake are a kind of special automatic actuators, which transmit torque through the magnetic powder filled in the working gap. Changing the excitation current can change the magnetic state of the magnetic powder, thereby adjusting the transmitted torque.

It can be used for stepless speed regulation from zero to synchronous speed, suitable for high-speed fine-tuning and medium and small power speed regulation systems. It is also used in the unwinding or rewinding tension control system that adjusts the torque by adjusting the current to ensure that the tension remains constant during the winding process. The main feature of the slitting machine is that the magnetic powder clutch acts as a resistance device, which is controlled by the system to output a DC voltage to control the resistance generated by the magnetic powder clutch. The main advantage is that it is a passive device that can control a small tension. Its main disadvantage is that the speed cannot be high, and it is easy to cause high-speed friction of the magnetic powder during high-speed operation, resulting in high temperature, causing the magnetic powder clutch to heat up and shorten its life.发送反馈历史记录
