Abstract

La présente invention concerne un dispositif de coupe automatique de papier sanitaire comprenant : un élément de coupe comprimé (130) pour faire tourner deux rouleaux qui sont entraînés dans un état comprimé à l'aide d'un moteur d'entraînement de telle sorte que le papier sanitaire (10) est retiré vers le bas ; et un élément d'enroulement de papier sanitaire (150) pour enrouler du papier sanitaire (10) sous l'élément de coupe comprimé (130) autour d'une unité d'enroulement à l'aide du moteur d'entraînement dans une partie d'espace de rotation. La présente invention comprend un moyen de coupe séquentiel configuré de telle sorte que, lorsqu'une longueur appropriée de papier sanitaire est enroulée autour de l'unité d'enroulement, la rotation des rouleaux formés dans l'élément de coupe comprimé (130) est interrompue, et seul l'élément d'enroulement de papier sanitaire est mis en rotation de telle sorte qu'une extrémité de la ligne de coupe du papier sanitaire est d'abord rompue, et que la rupture se poursuit ensuite sur l'ensemble de la ligne de coupe du papier sanitaire. La présente invention est avantageuse en ce que le papier sanitaire peut être coupé facilement, la coupe de papier sanitaire est simplifiée par l'utilisation d'une force de traction concentrée tandis qu'une partie du papier sanitaire est comprimée, l'utilisateur n'a pas besoin de couper manuellement le papier sanitaire, et l'utilisateur peut dérouler facilement le papier sanitaire à partir de l'unité d'enroulement pour ensuite l'utiliser.
