Abstract

L'invention porte sur un dispositif de formation de corps en céramique crue de type à extrusion verticale, apte à réaliser une opération du pétrissage à la formation d'une argile de céramique dans une opération continue et qui peut produire en continu des corps formés en céramique crue (3) ayant une précision dimensionnelle élevée. Le dispositif pour la formation en continu des corps formés en céramique crue (3) possède une extrudeuse verticale (1), un dispositif de malaxage à vis (6), un mécanisme de support de corps formé (4), et un mécanisme de coupe (5). L'extrudeuse verticale (1) possède un cylindre vertical, une ouverture d'alimentation en argile de céramique disposée dans la partie supérieure du cylindre vertical, une enceinte de filière possédant un fond sur lequel une filière est montée, et une vis placée verticalement dans le cylindre de façon à distribuer verticalement l'argile de céramique distribuée à l'ouverture d'alimentation. Le dispositif de malaxage à vis (6) pétrit et désaère une matière première de céramique pour préparer l'argile de céramique et distribue l'argile de céramique préparée à l'extrudeuse verticale (1). Le mécanisme de support de corps formé (4) possède sur celui-ci une plaque de support (41) pour supporter la surface inférieure d'un corps formé en céramique (3) extrudé vers le bas à partir de la filière et permet à la plaque de support (41) de descendre de manière synchrone avec la vitesse de formation du corps formé en céramique (3) extrudé par l'extrudeuse verticale (1) pour éviter ainsi une déformation du corps formé en céramique (3) provoquée par son propre poids. Le mécanisme de coupe (5) coupe le corps formé en céramique (3) lorsqu'il atteint une longueur prédéfinie lors de son extrusion à partir de la filière.
