Abstract

L'invention concerne un mécanisme de mise sous tension de bande transporteuse, comprenant une bande transporteuse (201), une poulie d'entraînement (202) et une poulie entraînée (203), la bande transporteuse (201) étant enroulée sur la poulie d'entraînement (202) et la poulie entraînée (203), et la distance d'axe entre la poulie d'entraînement (202) et la poulie entraînée (203) étant réglable. La mise sous tension de la courroie de transmission est réalisée en changeant la distance d'axe entre les poulies, sans qu'il soit nécessaire d'utiliser une roue de mise sous tension pour mettre la bande transporteuse sous tension, et par conséquent, aucun des deux bords latéraux de la bande transporteuse ne risque de se déformer ; en conséquence, il peut être garanti qu'une transmission précise de la bande transporteuse est obtenue dans l'état où le côté lâche et le côté serré changent alternativement. La structure est simple, le fonctionnement est pratique, et l'utilisation et la popularisation sont faciles.
