The invention relates to a feeding device, and particularly to a raw material feeding device used in the production of rubber products. In order to solve the technical problems, the invention provides the raw material feeding device which is high in production efficiency and stirring speed, has an excellent stirring and grinding effect, and does not influence subsequent machining; the raw material feeding device provided by the invention for solving the technical problems comprises a left side plate, a first transverse plate, a discharging hopper, a first discharging pipe, a second transverse plate and the like, wherein the first transverse plate is mounted at the upper part on the right side surface of the left side plate in a bolted connection manner; the discharging hopper is mounted on the right side surface of the first transverse plate in a bolted connection manner; the second transverse plate is mounted at the lower part on the right side surface of the left side plate in a bolted connection manner; a mixing tank is mounted on the right side surface of the second transverse plate in a bolted connection manner. The raw material feeding device used in the production of rubber products has the benefits that through the coordination of steel balls and third springs, the raw materials can be stirred more uniformly and rapidly.
