The side walls of the four raw material frames 31 are all provided with transparent windows, and the four raw material frames 31 are fitted together. A discharge port is opened at the bottom of each raw material frame 31, and four guide pipes 21 are symmetrically connected to the top of the mixing barrel 2, and the guide pipes 21 are directly opposite to the discharge port at the bottom of the raw material frame 31.

[0026] like Figure 3 and Figure 4As shown, in the embodiment of the present invention, a guide cylinder 32, a pressurizing mechanism 4 and a round cover 5 are also included. The guide cylinder 32 is fixedly arranged in the middle of the limiting frame 3. The pressurizing mechanism 4 includes a slide bar 41, an extrusion frame 42, an elastic member I43, a ring frame 44, a screw 45 and a fan-shaped plate 46. A ring frame 44 is slidably arranged on the outer wall of the guide cylinder 32, and a slide bar 41 is slidably arranged in the guide cylinder 32. An elastic member I43 is arranged between the ring frame 44 and the slide bar 41.
