How does paper slitter rewinder machine work?

The working principle of the paper slitter rewinder machine is as follows:
1. Unwinding part
The large roll of paper is installed on the unwinding shaft, and the unwinding shaft is rotated at a uniform speed by a motor drive or other power device to release the paper. The unwinding part is usually equipped with a tension control system, which detects the tension of the paper through a sensor and adjusts the unwinding speed according to the preset tension value to keep the paper in an appropriate tension state during the unwinding process. This prevents the paper from being loose or too tight, affecting the subsequent slitting and rewinding quality.

2. Slitting part
Cutter system: When the paper passes through the slitting part, a set of circular blades or other knives will slit it horizontally into narrow rolls of the required width. The position and spacing of the knives can be adjusted according to the requirements of the slitting width.
Slitting method: Slitting can be done by flat knife slitting, circular knife slitting and other different methods. Flat knife slitting is suitable for thicker paper, while circular knife slitting is suitable for thinner paper, with the advantages of fast slitting speed and high precision.
Guide device: In order to ensure that the paper maintains a straight line during the slitting process, the slitting part is usually equipped with guide devices, such as guide rollers, guide plates, etc. These guide devices can guide the paper to pass through the cutter accurately to ensure the accuracy of the slitting size.

3. Rewinding part
Rewinding shaft: The narrow roll paper after slitting enters the rewinding part and is wound on the rewinding shaft. The rewinding shaft is driven by a motor and rotates at a certain speed to rewind the paper into a neat and tight roll.
Tension control: During the rewinding process, a tension control system is also required to keep the tension of the paper stable. The tension control system detects the tension of the paper through a sensor and adjusts the speed of the rewinding shaft according to the preset tension value to ensure that the rewound roll has good flatness and tightness.
Roll diameter detection: In order to control the diameter of the rewound roll, the rewinding part is usually equipped with a roll diameter detection device. When the roll diameter reaches the preset value, the equipment will automatically stop or change the roll.

4. Electrical control system
The electrical control system is the core part of the paper slitter rewinder machine, which is responsible for precise control of various parts of the equipment. The electrical control system usually consists of PLC (Programmable Logic Controller), touch screen, sensor, motor driver, etc. The operator can set parameters such as slitting width, rewinding speed, tension, etc. through the touch screen, and monitor the operating status of the equipment in real time. PLC controls the motor speed, tool position, tension, etc. according to the preset parameters and the signal feedback from the sensor to realize the automatic operation of the equipment. At the same time, the electrical control system also has fault diagnosis and protection functions. When the equipment fails, it can issue an alarm in time and take corresponding protection measures to ensure the safe operation of the equipment.
