Guilotine cutters

1. Basic principle

Frequency converter regulates the speed and torque of the motor by changing the working frequency of the motor. The use of frequency converter in paper cutting machine can precisely control the cutting speed and the movement of knives, so as to improve the cutting accuracy and productivity.


2. Frequency conversion control
The method of frequency converter to regulate the motor speed is realized by changing the frequency of input current. Generally speaking, the speed of the motor is directly proportional to the frequency of the input current. Therefore, by adjusting the frequency, precise control of the paper cutter can be realized.


3. Advantages of application in paper cutting machine
Precise control: the frequency converter can provide continuously adjustable output speed, which makes the paper cutting length more accurate.
Energy-saving effect: In low-speed operation, the frequency converter reduces motor energy consumption, which is more energy-saving than the fixed-speed drive method.
Reduce mechanical wear: through smooth acceleration and deceleration curves, frequency converter can effectively reduce the impact and wear of mechanical parts, prolonging the service life of the equipment.
Overload protection: Frequency converter usually has over-current, over-voltage and over-load protection, which can ensure that the equipment automatically stops when there is an abnormal situation to prevent damage.

4. Easy operation and multi-function
The inverter has a human-machine interface, through simple programming and operation interface, users can easily set and adjust the cutting speed, length and other parameters of the paper cutter. At the same time, the frequency converter also supports a variety of operating modes, such as constant speed operation, constant torque operation, etc., to meet different process requirements.


5. Communication and automation
Many inverters support communication with PLC, SCADA and other automation control systems. Through these communication interfaces, the paper cutter can realize automation control and improve the automation and efficiency of the production line.


Conclusion
Through the use of inverters, paper cutters can not only achieve accurate speed control and efficient energy utilization, but also reduce mechanical wear and improve the service life of the equipment, and overall improve equipment performance and productivity. Therefore, the application of frequency converters in modern paper cutting machines is particularly important.
