How to achieve constant linear speed of slitting and rewinding machine?

The realization of constant linear velocity (CLV) by the slitter rewinder machine mainly relies on the following key technologies:

Variable frequency drive technology: Slitter rewinder machines are usually equipped with variable frequency drives, which can precisely control the running speed of the motor. By adjusting the motor speed, the material can be maintained at a constant linear speed during the slitting and rewinding processes.

Tension control system: The realization of constant linear speed requires precise control of the tension of the material. The automatic tension control system can automatically adjust the tension according to the thickness, elasticity and other characteristics of the material, as well as load changes during slitting and rewinding, to maintain the flatness of the material and prevent stretching or wrinkles.

Synchronous control technology: All aspects of unwinding, slitting and rewinding in the slitter rewinder machine need to be synchronized. The synchronous control system ensures that the speed of each part matches to avoid material damage or reduced production efficiency caused by speed mismatch.

PLC control: The programmable logic controller is the brain of the slitter rewinder machine. It can control the entire slitting and rewinding process according to the preset program. PLC can monitor and adjust the speed of each part in real time to ensure the realization of constant linear speed.

Photoelectric sensor: During the slitting and rewinding process, the photoelectric sensor can monitor the running status of the material in real time, such as detecting whether there is material, whether the material is flat, etc. The sensor data is fed back to the control system to adjust equipment operating parameters.

Material detection and feedback: By online monitoring of parameters such as material thickness and width, the control system can adjust the speed in real time according to the actual state of the material to ensure the realization of a constant linear speed.

Operation interface: The operation interface of the slitter rewinder machine allows the operator to set the required line speed, and the control system will automatically adjust the equipment operating parameters according to the operator's settings to achieve a constant line speed.

Through the combined use of these technologies, the slitter rewinder machine can maintain a constant linear speed under different working conditions, thereby improving the accuracy and efficiency of slitting and rewinding and ensuring product quality.
