Belt-tensioning and deviation-regulating device of belt conveyer

The utility model relates to a belt-tensioning and deviation-regulating device of a belt conveyer, which is installed below a machine frame and above a belt and is composed of a circular shaft rod, a movable frame, and a deviation-regulating gravity roller which supports on the belt by means of self weight. The utility model can lead a belt machine to keep definite values for belt tension when materials change continuously and runs, and consequently, the precision of an electronic belt scale can be ensured. Both ends of the utility model are provided with deviation-regulating gravities with inverse conical structures. The roller can automatically regulate the deviation of the belt, can ensure the normal running of the belt machine, and can improve the precision of a belt scale. The belt-tensioning and deviation-regulating device of a belt conveyer simple structure, strong practicality, and obvious effects of solving belt tension and regulating deviation.
