Abstract
(EN) The present application provides a 3D printer and a belt tensioning apparatus thereof. The belt tensioning apparatus comprises a first synchronous wheel, a second synchronous wheel, a synchronous belt, a first adjustment block, a second adjustment block, and an adjustment member. The first synchronous wheel and the second synchronous wheel are connected by means of the synchronous belt, and the synchronous belt is an open-type toothed synchronous belt. The first adjustment block is connected to one open end of the synchronous belt, and is provided with a first adjustment hole. The second adjustment block is connected to the other open end of the synchronous belt, and is provided with a second adjustment hole. The adjustment member is connected to the first adjustment hole and the second adjustment hole for driving the first adjustment block and the second adjustment block to move toward each other or move back to back. According to the present application, the tensioning degree of the synchronous belt can be conveniently adjusted.
(FR) La présente demande concerne une imprimante 3D et son appareil de tension de courroie. L'appareil de tension de courroie comprend une première roue synchrone, une seconde roue synchrone, une courroie synchrone, un premier bloc de réglage, un second bloc de réglage et un élément de réglage. La première roue synchrone et la seconde roue synchrone sont reliées au moyen de la courroie synchrone, et la courroie synchrone est une courroie synchrone dentée de type ouvert. Le premier bloc de réglage est relié à une extrémité ouverte de la courroie synchrone, et présente un premier trou de réglage. Le second bloc de réglage est relié à l'autre extrémité ouverte de la courroie synchrone, et présente un second trou de réglage. L'élément de réglage est relié au premier trou de réglage et au second trou de réglage pour amener le premier bloc de réglage et le second bloc de réglage à se déplacer l'un vers l'autre ou dos à dos. Selon la présente demande, le degré de tension de la courroie synchrone peut être réglé de manière commode.
(ZH) 本申请提供一种3D打印机及其皮带张紧装置，皮带张紧装置包括第一同步轮、第二同步轮、同步带、第一调节块、第二调节块及调节件。第一同步轮与第二同步轮通过同步带连接，同步带为开口式齿形同步带。第一调节块与同步带的一开口端连接，第一调节块设置有第一调节孔。第二调节块与同步带的另一开口端连接，第二调节块设置有第二调节孔。调节件与第一调节孔及第二调节孔连接，用于驱动第一调节块与第二调节块相向运动，或者相背运动。本申请可实现方便地调节同步带的张紧程度。
