Turnover mechanism for gas cylinder liner

The invention provides a turnover mechanism for a gas cylinder inner container. The turnover mechanism comprises a lathe bed rack, a turnover frame, a driving assembly, a feeding and discharging device and a control system. The bed body rack is of a frame structure which is formed by welding square tubes and is provided with an opening in the side end; the overturning frame is arranged close to the open end of the frame structure, one end of the overturning frame is rotationally connected into the frame structure, and the other end of the overturning frame is fixedly connected with the feeding and discharging device. One end of the driving assembly is rotationally connected into the frame structure of the lathe bed rack, and the other end of the driving assembly is rotationally connected with the feeding and discharging device. The feeding and discharging device is used for bearing the gas cylinder inner container and is driven by the driving assembly to rotate around one end of the overturning frame. The con
