The invention discloses a raw material belt winding machine. The raw material belt winding machine comprises a material winding disc with a central through hole, and an annular groove for winding a raw material belt is formed in the outer side wall of the material winding disc. The raw material belt winding machine is characterized in that the annular groove is internally provided with two annularsupport rings in a sleeved mode, and the support rings are rotatably matched with the material winding disc; the two support rings are arranged at intervals in the axial direction of the material winding disc, and a material passing channel is arranged at the position, located between the two support rings, in the annular groove; the material passing channel is in communication with the central through hole of the material winding disc, and the raw material belt is wound on the support rings in the annular groove in the own length direction; and a material belt head of the innermost ring of the raw material belt extends into the central through hole through the material passing channel. The raw material belt winding machine can enable the raw material belt to be continuously wound on a workpiece to be wound, and the raw material belt wound on the workpiece is continuously flat, so that the raw material belt winding process is easy to operate and good in leakproofness, and the user operation is facilitated.
