At this time, the raw materials and masterbatch fall on the material distributing disc 51, and the raw materials and masterbatch are dialed around through the material distributing disc 51 with a conical frustum structure. At the same time, the arc-shaped dial 52 is used to increase the dialing force. Control the third motor 60 to work, and drive the mixing cylinder 56 to rotate through the meshing gears 59 and gear ring 58. The raw materials and masterbatch dialed from the material distributing disc 51 are thrown onto the inner wall of the mixing cylinder 56, and the uniform mixing of the raw materials and masterbatch is realized through the rotating mixing cylinder 56. During this process, the movement of the raw materials and masterbatch is limited by the arc-shaped dial 52 to increase the mixing effect.
