The plastic bag sealing circuit is composed of power supply circuit and heating control circuit, the circuit is shown as the chart. Power supply circuit is composed of the power button S, resistors R1, R2, rectifier diode VD1 and filter capacitor C1. Heating control circuit consists of transistor V, thyristor VT, resistors R4 ~ R6, potentiometer RP, power transformer T, light-emitting diode VL and strip heater EH. power button S is controlled by the heating operating handle. When people use it, the plastic bag should be pressed on the strip heater EH, and after pressing the operating handle, the AC 220V voltage is limited and bucked by R1, rectified by VD1 and filtered by C1, then it provides DC operating power for V by R4, RP and R5.
