Description

Technical Field

[0001] The utility model relates to the field of extruders, in particular to a planetary extruder with automatic deashing and degassing. Background Art

[0002] The planetary screw extruder is an extruder in which the spiral middle section (i.e., plasticizing section) of the screw or the entire screw (only the feeding section is not a planetary screw) is a planetary screw structure. When working, the central screw is the active screw, and its outer circle has multiple small-diameter screws meshing and rotating with it. These small-diameter screws can both rotate on their own and revolve around the central screw. This is because the outer periphery of the small screw is meshed with an outer jacket with spiral teeth. This outer jacket is also a barrel, which is fixed to the front and rear barrels with bolts. The thread section of the screw is an involute tooth shape, and the spiral is a multi-start thread.
