Problems solved by technology

[0003] At present, the control method of the slip motor controller at home and abroad is: the slip motor is composed of an asynchronous motor and an electromagnetic slip clutch, and there is also a speed measuring device, and the electric signal obtained by the speed is fed back and compared to amplify and control the electromagnetic slip clutch The current achieves the purpose of manual given speed regulation. This method has the following disadvantages: 1) The speed characteristic is unstable; 2) There is no closed-loop automatic detection and adjustment function; 3) There is no pure torque function

Embodiment Construction

[0042] Control principle: The tension developed by the material during the production and processing process is converted into an electrical signal through the pressure displacement sensor; or through the swing rod device composed of the cylinder, the rocking rod and the encoder, the position of the rocking rod that the material passes through is adjusted by adjusting the air pressure Change, calculate the number of pulses of the encoder, convert the pulse equivalent into an electrical signal, or convert the angle change of the potentiometer into an electrical signal in the same way; thus output a variable linear DC voltage DC 0V-5V (volts) Or 0V-10V (volt), current 0mA-200mA (milliampere) voltage and current, the tension effect on the material is converted into an electrical signal and then sent to the controller for comparison with the set standard value. When the detected value is greater than or less than the standard value When the value is set, the controller automaticall...

Abstract

The invention relates to a slip motor automatic control device. The device comprises a slip motor, a tension signal acquisition device and a slip motor controller, wherein the tension signal acquisition device is used for converting the tension expanded when materials are processed into a tension signal; and the slip motor controller is used for comparing the tension signal with the preset normal value and automatically controlling the slip motor according to the comparison result. The device adopts the closed loop tension automatic control mode, and sets the normal value according to the characteristics of the materials; and when a tension senor detects a tension error of the materials, the voltage and the current needed by the slip motor are automatically regulated and outputted after automatic comparison, so that the automatic circulation functions of target determining, automatic detection, automatic comparison and automatic regulation are achieved.
