Conveying line for photoelectric sorting of steel balls

The utility model belongs to the technical field of conveying lines, and discloses a conveying line for photoelectric sorting of steel balls, which comprises a rack, a photoelectric detection equipment body is arranged above the rack, a positioning block is fixedly mounted on the bottom surface of the photoelectric detection equipment body, a fixing plate is fixedly mounted in the middle of the rack, and the photoelectric detection equipment body is fixedly mounted on the fixing plate. A first electromagnet is fixedly installed on the bottom face of the fixing plate, a support is fixedly installed at the left end of the rack, and a second electromagnet is fixedly installed on the left side of the top face of the support. The photoelectric detection equipment body is pressed downwards through the gravity of the steel ball, so that the photoelectric detection equipment body sinks the length of the radius value of the steel ball relative to the feeding position, the feeding position and the feeding pipe are stag
