Title (EN) MATERIAL EXTRUDER ASSEMBLY
(FR) ENSEMBLE EXTRUDEUSE DE MATÉRIAU
Abstract:
(EN) A material extruding assembly is provided with an extruder (2) provided with an hollow body (5) extending along a longitudinal axis (A), with at least one extrusion screw (6), which is housed in the hollow body (5) and is rotatable about a first rotation axis (B1), and with a processing channel (7), which is substantially defined by the space comprised between the least one extrusion screw (6) and the cylindrical inner surface (8) of the hollow body (5); with at least one pumping device (3) provided with a cylindrical rotor (11) rotatable about a second rotation axis (B2) and having an outer face (12) provided with at least one groove (13), with a stator (15) provided with a cylindrical seat (16), wherein the rotor (11) is housed and coupled in sliding manner to the rotor (11), and with a pumping channel (17), which is substantially defined by the space comprised between the rotor (11) and the cylindrical inner surface (19) of the stator (15); wherein the processing channel (7) and the pumping channel (17) are in direct communication through a passage (20), which is defined by the intersection of the extension of the cylindrical inner surface (19) of the stator (15) and the extension of the cylindrical inner surface (8) of the hollow body (5).
(FR) La présente invention concerne un ensemble d'extrusion de matériau pourvu d'une extrudeuse (2) pourvue d'un corps creux (5) s'étendant le long d'un axe longitudinal (A), d'au moins une vis d'extrusion (6), qui est logée dans le corps creux (5) et qui peut se mettre en rotation autour d'un premier axe de rotation (B1), et d'un canal de traitement (7), qui est sensiblement défini par l'espace compris entre la au moins une vis d'extrusion (6) et la surface interne cylindrique (8) du corps creux (5) ; au moins un dispositif de pompage (3) pourvu d'un rotor cylindrique (11) pouvant se mettre en rotation autour d'un deuxième axe de rotation (B2) et présentant une face extérieure (12) pourvue d'au moins une rainure (13), d'un stator (15) pourvu d'un siège cylindrique (16), le rotor (11) étant logé et accouplé de manière coulissante au rotor (11), et d'un canal de pompage (17), qui est sensiblement défini par l'espace compris entre le rotor (11) et la surface interne cylindrique (19) du stator (15) ; le canal de traitement (7) et le canal de pompage (17) étant en communication directe à travers un passage (20), qui est défini par l'intersection de l'extension de la surface interne cylindrique (19) du stator (15) et l'extension de la surface interne cylindrique (8) du corps creux (5).
