Abstract

L'invention concerne un dispositif de granulation de matières plastiques comprenant une tête (3) de granulation et une tête porte-lames (6) prévue à l'intérieur d'un boîtier (5) pouvant être raccordé à la tête de granulation, dont l'arbre (8) de tête porte-lames pouvant être entraîné par un moteur (7) traverse une paroi frontale (9) du boîtier qui est monté de manière à pouvoir coulisser sur un guidage (12) s'étendant en direction de l'arbre (8) de tête porte-lames. L'invention vise à régler la pression de compression de la tête porte-lames sur le disque perforé (4) de la tête de granulation. L'invention propose à cet effet que le moteur disposé sur un chariot (11) monté de manière à pouvoir coulisser en direction de l'arbre de tête porte-lames soit guidé de manière à pouvoir coulisser axialement sur un épaulement de guidage (13) de la paroi frontale du boîtier, et que le chariot soit relié à un entraînement à broche (16) prenant appui sur le boîtier.
