Abstract

L'invention concerne un mécanisme (1) de changement de vitesse de feuille de type à transport continu et un procédé pour un dispositif d'étanchéité à ultrasons. Le mécanisme (1) de changement de vitesse de feuille est disposé au-dessous de deux ensembles de dispositifs à ultrasons (2) et comprend une came (3), une tige oscillante (4), un bras oscillant (5), un premier rouleau flottant (6) et un deuxième rouleau flottant (7). Une extrémité de la tige oscillante (4) est reliée à la came (3) et l'autre extrémité de la tige oscillante (4) est reliée à une extrémité du bras oscillant (5). Le premier rouleau flottant (6) et le deuxième rouleau flottant (7) sont disposés respectivement sur les deux extrémités du bras oscillant (5). Le premier rouleau flottant (6) est disposé sur une extrémité d'entrée d'un premier ensemble de dispositifs à ultrasons (2) et le deuxième rouleau flottant (7) est disposé sur une extrémité de sortie d'un deuxième ensemble de dispositifs à ultrasons (2). Le procédé de changement de vitesse de feuille comprend les étapes suivantes : lorsque la came (3) tourne, le premier rouleau flottant (6) et le deuxième rouleau flottant (7) sont entraînés par la tige oscillante (4) et le bras oscillant (5) pour osciller alternativement et verticalement. Lorsque le premier rouleau flottant (6) oscille jusqu'à la position la plus élevée, les deux ensembles de dispositifs à ultrasons (2) sont dans un état de non-fonctionnement. Lorsque le premier rouleau flottant (6) oscille vers la position la plus basse, les deux ensembles de dispositifs à ultrasons (2) sont dans un état de fonctionnement. Le mécanisme de changement de vitesse permet une meilleure adaptation d'un dispositif d'étanchéité à ultrasons à un transport à grande vitesse d'une feuille continue, ce qui améliore ainsi efficacement la stabilité de l'effet d'étanchéité du dispositif d'étanchéité.
