Automatic roller wheel correction and regulation system of decorating machine conveyor belt

Disclosed is an automatic roller wheel correction and regulation system of a decorating machine conveyor belt. The automatic roller wheel correction and regulation system of the decorating machine conveyor belt monitors speed of a direct current motor which drives a decorating machine roller through a tachometer generator in real time, feeds the speed of the direct current motor back to a DSP (digital signal processor), and the DSP achieves regulation on the rotation speed of the direct current motor by regulating output voltage of a three phase rectifying circuit, and simultaneously harmonizes and controls speed of a stepping motor of the decorating machine conveyor belt, and therefore the purpose of automatically correcting and regulating a roller wheel of the decorating machine conveyor belt is achieved.
