采用气缸驱动时,因为在其行程两端减速困难,将产生冲击,可能使搬运物落下,同时对导向装置、气缸以及其它设备都有不良影响。所以常常在外部设置缓冲装置。本机构是在活塞杆伸出时,带动与其相连的齿条沿齿条导向移动,并使轴心与齿条导向相固定的小齿轮回转。与此同时,通过连结在齿轮上的曲柄,使夹爪移动到传送带上,完成供料动作。如果齿轮的直径和气缸的行程相同,在夹爪行程
When using cylinder drive, because of the difficulty of decelerating at both ends of the stroke, impact will occur, which may cause the object to fall down, and will adversely affect the guide, cylinder and other equipment. So often set in the external buffer device. In the mechanism, when the piston rod is extended, the rack which is connected with the rack rod is driven to move along the rack guide, and the pinion which is fixed with the guide shaft and the rack guide is rotated. At the same time, through the gear connected to the crank, the jaws move to the conveyor belt, to complete the feeding action. If the gear diameter and cylinder stroke the same in the jaw stroke
