Abstract

An internal mixing extruder includes an internal mixing mechanism including a mixing chamber, where the mixing chamber includes a rear end provided with a first feed port, and a front end provided with a first discharge port, and a rotor is provided in the mixing chamber along a front-rear direction; an extrusion mechanism located below the internal mixing mechanism, where the extrusion mechanism includes an extruding chamber, the extruding chamber includes a rear end provided with a second feed port, and a front end provided with a mold, and a screw is provided in the extruding chamber along the front-rear direction; and a hopper, where the hopper is connected between the first discharge port and the second feed port. Materials are plasticized fully in the internal mixing mechanism. The fully plasticized materials enter the hopper. The hopper conveys to-be-extruded materials to the extrusion mechanism in a forced feeding manner.
