Raw material wound roll loading and unloading mechanism

The utility model relates to a raw material wound roll loading and unloading mechanism, which is used for loading and unloading raw material wound rolls with a roll core provided with a hollow part on a production line. The raw material wound roll loading and unloading mechanism comprises a rotating shaft and a raw material wound roll carrying device, wherein the raw material wound roll carrying device comprises a support rod, an ascending and descending mechanism and a vehicle body, either the butt joint end of the support rod or the butt joint end of the rotating shaft is provided with a shaft core alignment pin, the other one of the butt joint end of the support rod or the butt joint end of the rotating shaft is provided with a shaft core alignment hole, and after the shaft core alignment pin is embedded into the shaft core alignment hole, a shaft core of the support rod and a shaft core of the rotating shaft become consistent. The raw material wound roll loading and unloading mechanism according to the utility model has the advantages that during the raw material wound roll loading and unloading, the shaft core alignment pin is embedded into the shaft core alignment hole, so that whether the shaft core of the rotating shaft is consistent with the shaft core of the roll core or not can be easily judged.
