Title
(DE) ANTRIEB FÜR EINE MISCHVORRICHTUNG MIT BESCHICKUNGSSCHACHT, UND DARAUF BEZOGENES VERFAHREN
(EN) DRIVE FOR A MIXING DEVICE WITH A FEED SHAFT, AND METHOD RELATED THERETO
(FR) ENTRAÎNEMENT POUR UN DISPOSITIF DE MÉLANGE COMPRENANT UN PUITS DE CHARGEMENT ET PROCÉDÉ ASSOCIÉ
Abstract
(DE) Mischvorrichtung (100) für eine Kautschuk-Mischung umfassend eine Mischkammer (1) zum Mischen der Kautschuk-Mischung, einen Beschickungsschacht (2) zur Zuführung der Kautschuk- Mischung in die Mischkammer (1), einen Stempel (4), der in dem Beschickungsschacht (2) angeordnet ist und der dazu ausgebildet ist, die Kautschuk-Mischung aus dem Beschickungsschacht (2) in die Mischkammer (1) zu pressen, und einen Hauptantrieb (9) und einen Nebenantrieb (8), die dazu ausgebildet sind, den Stempel (4) zu bewegen, wobei der Hauptantrieb (9) so ausgebildet ist, dass er eine höhere Leistung als der Nebenantrieb (8) aufbringt und dazu ausgebildet ist, den Stempel (4) anzutreiben, wenn der Stempel (4) in Kontakt mit der Kautschuk-Mischung ist, und der Nebenantrieb (8) dazu ausgebildet ist, den Stempel (4) anzutreiben, wenn der Stempel (4) nicht in Kontakt mit der Kautschuk-Mischung ist.
(EN) The invention relates to a mixing device (100) for a rubber mixture, comprising a mixing chamber (1) for mixing the rubber mixture, a feed shaft (2) for supplying the rubber mixture into the mixing chamber (1), a plunger (4) which is arranged in the feed shaft (2) and is designed to press the rubber mixture out of the feed shaft (2) and into the mixing chamber (1), and a main drive (9) and an auxiliary drive (8) which are designed to move the plunger (4), wherein the main drive (9) is designed to apply a greater output than the auxiliary drive (8) and is designed to drive the plunger (4) when the plunger (4) is in contact with the rubber mixture, and the auxiliary drive (8) is designed to drive the plunger (4) when the plunger (4) is not in contact with the rubber mixture.
(FR) L'invention concerne un dispositif de mélange (100) pour un mélange de caoutchouc, qui comprend une chambre de mélange (1) pour mélanger le mélange de caoutchouc, un puits de chargement (2) pour amener le mélange de caoutchouc dans la chambre de mélange (1), un poinçon (4) qui est disposé dans le puits de chargement (2) et qui est conçu pour faire sortir le mélange de caoutchouc du puits de chargement (2) et le faire entrer dans la chambre de mélange (1), et un entraînement principal (9) et un entraînement secondaire (8), qui sont conçus pour déplacer le poinçon (4) ; l'entraînement principal (9) étant conçu pour appliquer une puissance supérieure à celle de l'entraînement secondaire (8) et étant conçu pour entraîner le poinçon (4) lorsque ledit poinçon (4) est en contact avec le mélange de caoutchouc, et l'entraînement secondaire (8) étant conçu pour entraîner le poinçon (4) lorsque ledit poinçon (4) n'est pas en contact avec le mélange de caoutchouc.
