Include extending list for detecting the multi-functional ultrasonic range finder, analog-to-digital conversion module, PLC for leading material coil diameter size on the position that goes into operation
Member, for receiving touch screen from externally input material initial tension, for being driven according to material initial tension and calendering owner
Motor speed exports PLC, the frequency converter for controlling variable-frequency motor output torque, variable-frequency motor and the rotation of Frequency Converter Control parameter
Turn encoder；The ultrasonic range finder connects the analog-to-digital conversion module, and the analog-to-digital conversion module connects the PLC extensions
Unit, the PLC expanding elements connect the PLC, the PLC connections touch screen and the frequency converter, the frequency converter
The variable-frequency motor and the rotary encoder are connected, the variable-frequency motor connects the rotary encoder.
Further include the direct-current switch power supply for providing operating current, connects the ultrasonic range finder.
The PLC expanding elements are I/O expansion modules.
The utility model has the following advantages and advantageous effect：
1, the utility model overcomes traditional control method, and tension force bad phenomenon when material coil diameter size variation is answered
It is combined with vector converter technology and ultrasonic range finder, control is multi-functional to lead the initial tension that goes into operation, and can follow calendering host row
Vehicle speed and material coil diameter size variation apply initial tension to material, ensure that cord does not have cloth pleat when rolling rubberizing while going back
It is not subject to crushing, improves adhesive plaster quality.
2, the utility model leads the position that goes into operation after vector converter technology and ultrasonic range finder are applied to calender, makes calendering
Machine cord leads out feeder process and applies constant initial tension, and applicable raw material range is wide, and simulation material is suffered in practical applications
