Rotating wheel type bottle blank overturning mechanism

The invention discloses a rotating wheel type bottle blank overturning mechanism. The rotating wheel type bottle blank overturning mechanism comprises a shell, a driving mechanism fixedly installed on the shell and a rotating wheel mechanism installed in the shell; an output shaft of the driving mechanism extends into the shell, and the rotating wheel mechanism is driven to rotate by the driving mechanism; a loophole allowing a bottle blank to input and output is formed in the top of the shell; the rotating wheel mechanism comprises a rotating wheel mounted on the output shaft; the rotating wheel comprises a wheel hub and a plurality of buffering baffles extending outwards in the radial direction of the wheel hub; the multiple buffering baffles are evenly distributed in the circumferential direction of the wheel hub, and a containing channel used for containing the bottle blank is formed between every two adjacent buffering baffles; and a guardrail assembly for preventing the bottle blank from falling down fr
