The EMI filter, the rectifier, the voltage regulator and the DC voltage converter are electrically connected in sequence, and the power signal output by the DC voltage converter provides the required voltage source for the device.
[0030] When detecting foreign objects in food, the user turns on the power and adjusts the speed of the conveyor belt through the control button. The MCU processing chip receives the signal from the photoelectric switch and controls the first relay to turn on the X-ray detector to detect foreign objects in the food passing through the detection box.
