[0044] It is worth mentioning that the material transfer mechanism is not only one, and each material transfer mechanism sequentially receives the detected objects sent by the material taking mechanism, and then distributes them to the subsequent detection station 3, thereby greatly improving the detection efficiency. The X-ray detection machine 31 here can be directly integrated with the existing online detection equipment, which will not be described here.
