Title (EN) DEVICE FOR CONTINUOUSLY DOSING PLASTIC MATERIAL, ESPECIALLY FOR A UNIT FOR PRODUCING COMPONENTS MADE OF PLASTIC MATERIAL OR THE LIKE
(FR) DISPOSITIF DE DOSAGE EN CONTINU DE MATIERE PLASTIQUE NOTAMMENT POUR UNITE DE PRODUCTION DE COMPOSANTS EN MATIERE PLASTIQUE OU SIMILAIRE
Abstract:
(EN) The invention relates to a dosing device (8) for dosing plastic material or the like, comprising an extrusion head (10) that has a dispensing opening (12) commonly called a die and a punch (11) extending into the dispensing opening (12), coaxially thereto, for continuously extruding a plastic material in the form of a tubular or annular body, and cutting means (14) for separating a dose of said plastic material in the form of a tubular or annular section. Said device is characterised in that said cutting means (14) consist of at least two elements (16) having at least one sharp or cutting edge, extending on either side of the dispensing opening (12) and secured to driving means generating a symmetrical movement of said elements (15, 16) in relation to the longitudinal axis of the extruded tubular body until the tubular body is severed by said elements in order to form a dose.
(FR) La présente invention concerne un dispositif de dosage (8) de matière plastique ou similaire comprenant une tête d'extrusion (10) ayant un orifice de distribution (12) communément appelé filière et un poinçon (11) s'étendant dans l'orifice de distribution (12) coaxialement à celui-ci pour extruder en continu un matériau plastique sous la forme d'un corps tubulaire ou annulaire et des moyens de coupe (14) pour séparer une dose dudit matériau plastique sous la forme d'une section tubulaire ou annulaire; ledit dispositif est remarquable en ce que lesdits moyens de coupe (14) sont constitués d'au moins deux éléments (16) présentant au moins une arrête vive ou tranchante, s'étendant de part et d'autre de l'orifice de distribution (12), et solidaires de moyens d'entraînement procurant un mouvement symétrique desdits éléments (15,16) par rapport à l'axe longitudinal du corps tubulaire extrudé jusqu'à ce que le corps tubulaire soit sectionné par lesdits éléments pour former une dose.
