Due to its good feeding performance, mixing and plasticizing performance, exhaust performance, extrusion stability and other characteristics, it has been widely used in the molding processing of extruded products. When adapting to different working environments or operating requirements, traditional twin-screw extruders may need to replace equipment of different specifications or make complex adjustments. For example, the Chinese patent discloses a "twin-screw extruder" with an application number of "202122740814.7". A connecting sleeve is sleeved on the outer side of the connecting shaft, and the outer wall of the connecting sleeve is fixedly connected to a plurality of pusher plates distributed in a ring array.
