How does turret slitter rewinder machine work?
Dec 17, 2024
The working principle of the turret slitter rewinder machine is as follows:
1. Unwinding part
The large roll of raw materials to be slit is installed on the unwinding mechanism. The unwinding mechanism is usually equipped with a tension control system, which is driven by a motor or a pneumatic device to make the raw materials unfold smoothly under a certain tension. The tension control system will automatically adjust the unwinding tension according to different material properties and production requirements to ensure that the raw materials will not be too loose to cause deviation during the slitting process, nor will they be too tight to affect the physical properties of the material.
2. Slitting part
Turret structure: There are multiple slitting knife seats installed on the turret, and each knife seat is equipped with a circular blade or other slitting tool. The turret can rotate accurately under the drive of the motor to achieve rapid switching of different slitting knife seats.
Slitting process: When the raw material passes through the slitting part, according to the set slitting width, the blade on the corresponding slitting knife seat will slit the raw material horizontally into small rolls of the required width. The position and spacing of the slitting blades can be adjusted according to production requirements to ensure the accuracy of slitting.
Tool adjustment: Slitting tools can usually be fine-tuned to adapt to materials of different thicknesses and different slitting accuracy requirements. At the same time, the material and sharpness of the tool will also affect the slitting effect and quality.
3. Rewinding part
Rewinding mechanism: The slitting small roll material enters the rewinding part, and the rewinding mechanism is usually composed of one or more rewinding shafts. The rewinding shaft rotates under the drive of the motor to rewind the slitting small roll material into a neat and tight roll.
Tension control: During the rewinding process, a tension control system is also required to ensure the quality of the rewinding. The tension control system will automatically adjust the rewinding tension according to factors such as the diameter change of the roll and the production speed, so that the roll maintains the appropriate tightness during the rewinding process.
Roll diameter detection: The diameter of the rewinding roll is detected in real time through sensors and other devices. When the roll reaches the set diameter, the rewinder will automatically stop or change the roll.
4. Control system
The control system of the turret slitting rewinder is usually composed of PLC (programmable logic controller), touch screen, sensor and actuator. The operator can input slitting parameters such as slitting width, rewinding speed, tension, etc. through the touch screen. PLC controls the motor speed, turret rotation, tool position adjustment, etc. according to these parameters to realize the automatic operation of the equipment. At the same time, the sensor will monitor the operating status of the equipment in real time, such as tension, speed, reel diameter, etc., and feed this information back to PLC so that PLC can make real-time adjustments and fault diagnosis.
