The connecting plates 203 and the connecting plates 204 are rotatably connected to each other through the rotating rod 1 202. The inside of the feed hopper 3 is fixedly connected to an inner cylinder 211, and the outer wall of the inner cylinder 211 is fixedly connected to an electric heating wire 210. The hot wire 210 heats the inner cylinder 211 to heat the rubber solution and reduce its viscosity.
