Automatic workpiece conveying device

The invention relates to an automatic workpiece conveying device which comprises a steel frame body. The steel frame body is of a cuboid frame structure formed by connecting stand columns, long cross beams and wide cross beams end to end. The parts at one end of the steel frame body and along the two stand columns of the steel frame body are each provided with a loading lifting device, the loading lifting devices are provided and connected with electrical apparatus control system boxes, inlets are formed in the bottoms of the loading lifting devices, a row of horizontal roller paths are fixedly arranged in front of the inlets in a connection mode, iron drum circulating boxes are installed in the loading lifting devices, a row of rails arranged along the long cross beams of the steel frame body are connected to outlets in the upper portions of the loading lifting devices, feeding trolleys are installed on the upper faces of the rails, a plurality of hoppers are hung on the lower faces of the rails, the outer sides of the two loading lifting devices are each fixedly provided with a pedestrian path, and handrails are installed on the outer sides of the pedestrian paths. The automatic workpiece conveying device is simple in structure, the structure of automatic loading and automatic feeding is adopted, full automatic production is achieved, the production effect is improved, the labor intensity of workers is lowered, and labor is saved.
