Abstract

The utility model discloses a time switch controller for a servo motor for a packaging machine. The time switch controller comprises a time base circuit, a switch, a relay, a potentiometer, a diode, a light emitting diode, a triode, a bridge type rectification circuit, a transformer, a first capacitor, a second capacitor, a third capacitor, a first resistor, a second resistor, and a fourth resistor. The time switch controller is advantageous in that, when a button switch is pressed, the output terminal of the time base circuit outputs a high level, so that the triode is conducted, the relay pulls in, contacts pull in, and a commercial power output circuit is connected. In the meantime, a power supply charges the third capacitor via the potentiometer. When the input terminal voltage of the servo motor reaches 2/3 of the power supply voltage, the circuit overturns, the output terminal of the time base circuit is at a low level, so that the triode is cut off and output is converted from the high level to the low level, the triode is cut off and the relay is released, and the contacts cut off the commercial power output circuit.
