[0025] A cover plate is provided on the top of the housing 1, and the cover plate is opened and closed by a cylinder mechanism (not shown in the figure) for exporting the finished product. This is a common technical means in this field, and therefore is not shown in the figure.

[0026] The raw materials and compounding agents to be mixed are introduced into the mixing tank 301, mixed under the action of the stirring structure, and after preliminary mixing, they are transported to the inside of the introduction structure 2 through the introduction pipe 302, and under the action of the introduction structure 2, the preliminary mixed raw materials are introduced into the mixing chamber 101 for processing, thereby reducing the mixing time and improving the processing efficiency.

[0027] like Figure 1-5As shown, the stirring structure includes a driving motor 303 arranged on the top of the mixing tank 301, the output shaft of the driving motor 303 is fixedly connected to the rotating shaft 304, the lower end of the rotating shaft 304 passes through the mixing tank 301, and the surface of the rotating shaft 304 is fixedly connected to the stirring rods evenly distributed and located inside the mixing tank 301; the inner wall of the introduction pipe 302 is rotatably connected to the installation shaft 305, and the surface of the installation shaft 305 is provided with a transmission mechanism 307, the other end of the transmission mechanism 307 passes through the introduction pipe 302 and is fixedly connected to the surface of the rotating shaft 304, and the surface of the installation shaft 305 is fixedly connected to the second spiral conveying blade 306, and a protective shell 308 is arranged between the two introduction pipes 302, and the two ends of the protective shell 308 pass through and extend to the inside of the adjacent introduction pipe 302, the transmission mechanism 307 is located inside the protective shell 308, and the top of the protective shell 308 is fixedly connected to a protective sleeve 309, and the cross-sectional shape of the protective sleeve 309 is a flat-topped cone;

[0028] By starting the driving motor 303, the rotating shaft 304 can be driven to rotate, and in this process, the stirring rod can be driven to mix the raw materials and compounding agents in the mixing tank 301, and the mixed materials are discharged through the two inlet pipes 302. In this process, the rotating shaft 304 can drive its mounting shaft 305 to rotate under the action of the transmission mechanism 307, so that the second spiral conveying blade 306 can be used to smoothly convey it out of the interior of the inlet pipe 302, and further mix it during the conveying process of the second spiral conveying blade 306, which effectively improves the mixing effect of the materials;

[0029] The protection shell 308 is provided to prevent the material from affecting the use of the transmission mechanism 307 , and the protection sleeve 309 can prevent the material from piling up on the surface of the protection shell 308 .

The heat generated during the processing inside the internal mixing chamber 101 can be partially transferred to the interior of the conveying chamber 205 through the connecting port 206, so that the material introduced into the conveying chamber 205 by the inlet pipe 302 is preheated. At the same time, under the action of the first spiral conveying blade 204, the material can be further mixed and extruded and conveyed to the interior of the internal mixing chamber 101 for processing, which effectively improves the processing efficiency.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
