[0023] Through the setting of the distribution component, when feeding into the interior of the mixing barrel 1, the material will fall into the annular distribution shell 7.

The output shaft of the driving motor 2 will drive the annular distribution shell 7 to rotate through the rotating rod 3. When it rotates, it will drive the distribution tube 9 to rotate inside the mixing barrel 1. The raw materials in the annular distribution shell 7 will be evenly spread in the mixing barrel 1 layer by layer through the discharge hole 10 at the bottom of the distribution tube 9, thereby achieving the purpose of pre-mixing.
