Abstract

L'invention se rapporte à un mécanisme boucleur utilisé dans une machine à broderie de couleur informatisée, qui présente une structure simple et peut être fabriqué et assemblé facilement. Le mécanisme boucleur comporte une chambre de boucleur, sur laquelle est disposée la roue menante, l'un des côtés de cette chambre de boucleur étant doté d'un guide pour le siège du boucleur, et le siège du boucleur étant situé sur le guide. Plusieurs manchons de bouclage sont disposés longitudinalement sur le siège du boucleur, et chaque manchon de bouclage est composé d'une région de tête et d'une région axiale, et l'extérieur de la région de tête du manchon de bouclage étant doté d'un corps convexe qui a la possibilité d'entrer en contact avec la roue menante, et un trou de passage pour le fil étant situé suivant la direction axiale du manchon de bouclage. Le mécanisme se caractérise en ce que la région de tête du manchon de bouclage présente une forme de cône intégral dont la partie supérieure présente un trou de sortie du fil qui est dévié à partir du centre de cette partie supérieure, et dont la partie centrale présente un trou de positionnement d'aiguille, et dont la partie latérale présente un trou d'évacuation des fragments, qui est en communication avec le trou de positionnement d'aiguille. Ce mécanisme peut également comporter un manchon métallique dans la roue menante afin d'améliorer la fermeté du couplage.
