Title:
INTERNAL MIXING EXTRUDER
Document Type and Number:
WIPO Patent Application WO/2023/061336
Kind Code:
A1
Abstract:
The present application discloses an internal mixing extruder, comprising: an internal mixing mechanism, which comprises an internal mixing chamber, the rear end of the internal mixing chamber being provided with a first feed port, the front end being provided with a first discharge port, and the internal mixing chamber being internally provided with rotors arranged along the front and back; an extrusion mechanism, which is located below the internal mixing mechanism, the extrusion mechanism comprising an extrusion chamber, a second feed opening being provided at the rear end of the extrusion chamber, a mold being provided at the front end, and screw rods being provided in the extrusion chamber along the front and back; and a hopper, which is connected between the first discharge port and the second feed port. Materials are fully plasticized in the internal mixing mechanism, the fully plasticized materials enter the hopper, the hopper delivers materials to be extruded into the extrusion mechanism by using a forced feeding means, and the materials are fixed and formed by means of a mold after the extrusion process is completed. Therefore, the present application has a high automation degree, reduces manpower input, and eliminates a stirring procedure and a cooling procedure, thereby reducing energy waste, which is suitable for the application field of internal mixing extruders, and can produce the positive effect of high working efficiency.
