A second gear 13 is sleeved and coaxially fixedly connected to the outer wall of the first screw 8. The first gear 12 is meshingly connected with the second gear 13. The vertical rod 4 is connected to a stirring assembly 5. The extrusion screw 9 drives an extrusion assembly 7. The first screw 8 drives a cooling assembly 6.

[0025] The stirring assembly 5 includes a rotating rod 501 that penetrates the upper wall of the stirring box 2 and is rotatably connected thereto. The lower end of the rotating rod 501 is coaxially fixedly connected to the vertical rod 4. The outer wall of the rotating rod 501 is fixedly connected to a plurality of stirring rods 502 that are evenly distributed. Two feeding hoppers 503 are fixedly arranged and connected to the upper wall of the stirring box 2 for inputting raw materials. A motor 504 that drives the rotating rod 501 to rotate is fixedly arranged on the upper wall of the stirring box 2.

[0026] The extrusion assembly 7 includes a molding box 701 disposed above the base 1, and the interior of the mixing box 2 is connected to the interior of the molding box 701 through a connecting pipe 16. The molding box 701 is fixedly connected to the upper wall of the base 1 through two fixing seats 14, and the extrusion screw 9 is arranged through the side wall of the molding box 701 and is rotatably connected thereto.
