Abstract

L'invention concerne un dispositif d'ouverture de navette pour une navette interne d'une navette rotative d'une machine à broder. Le dispositif comprend un arbre principal (2) et un arbre de navette rotative (1) perpendiculaire à l'arbre principal (2). Une extrémité avant de l'arbre de navette rotative (1) est pourvue d'une navette rotative (10), et une extrémité arrière est pourvue d'un engrenage de navette rotative (11). Un engrenage d'arbre principal (20) est situé sur l'arbre principal (2), l'engrenage d'arbre principal (20) étant en prise avec l'engrenage de navette rotative (11) pour entraîner l'arbre de navette rotative (1) et la navette rotative (10) en rotation. Un arbre d'entraînement d'ouverture de navette (3) est agencé en parallèle sur un premier côté de l'arbre de navette rotative (1). Une came d'entraînement d'ouverture de navette (22) est située sur l'arbre principal (2), la came d'entraînement d'ouverture de navette (22) amenant l'arbre d'entraînement d'ouverture de navette (3) à se déplacer dans la direction axiale. L'arbre d'entraînement d'ouverture de navette (3) est agencé de façon mobile à l'intérieur d'un manchon d'arbre d'entraînement d'ouverture de navette (34). Un ressort de rappel d'ouverture de navette (33) est situé entre le manchon d'arbre d'entraînement d'ouverture de navette (34) et l'arbre d'entraînement d'ouverture de navette (3). Une extrémité avant de l'arbre d'entraînement d'ouverture de navette (3) est pourvu d'un crochet d'ouverture de navette (31), le crochet d'ouverture de navette (31) agissant avec une navette interne (101) pour entraîner la navette interne en rotation dans le sens des aiguilles d'une montre. Le dispositif d'ouverture de navette pour une navette interne d'une navette rotative d'une machine à broder réduit la pression entre une navette externe et la navette interne de la navette rotative par l'intermédiaire du crochet d'ouverture de navette entraînant la navette interne en rotation dans le sens des aiguilles d'une montre, et empêche un fil de se casser ou d'être endommagé lorsque le fil sort entre la navette interne et un crochet d'arrêt.
