The rotating part 200 comprises a rotating shaft 210, a rotating roller 220 and a gear 230. The rotating shaft 210 is rotatably arranged in the mixing cavity 110 and extends to outside of the shell 100 at one end. The rotating roller 220 is coaxially connected outside the rotating shaft 210. The rotating rollers 220 in the two sets of rotating parts 200 are spaced apart. The gear 230 is coaxially connected to the extended end of the rotating shaft 210. The gears 230 in the two sets of rotating parts 200 are meshed with each other. In actual use, driving force is provided for one set of rotating parts 200, for example, the rotating shaft 210 of one set is connected with the output end of an output motor. When the output motor is started, the set of rotating parts 200 can be rotated. Through the meshing of the gears 230 in the two sets of rotating parts 200, the rotating directions of the two rotating rollers 220 are opposite, so that the EPDM rubber particles in the mixing cavity 110 are mixed.

The inner feeding part 320 is arranged in the outer feeding part 310. The outer feeding part 310 and the inner feeding part 320 are used for feeding two different rubber particles into the mixing cavity 110.

[0027] In combination Figures 1-4 The upper edges of the outer down feeder 310 and the inner down feeder 320 are coplanar, and the lower edges of the outer down feeder 310 and the inner down feeder 320 are coplanar, that is, the top of the outer down feeder 310 and the top of the inner down feeder 320 have the same height, and the bottoms of the two have the same height, which is beneficial to plugging the top and the bottom; the upper edge of the outer channel 313 is higher than the upper edge of the outer material pipe 312, so that the outer channel 313 is communicated with the outer down feeder 310 at the height of the outer material bin 311, and the inlet is prevented from being plugged.
