Abstract
The invention discloses a use method of an adjustment device capable of rapidly adjusting tensile force of a conveyor belt. The use method includes the following steps that firstly, a belt is wound around a rectangular frame, and a pressure sensor at the tail end of an air cylinder performs detection recording on action force exerted on the rectangular frame and the belt; when the recorded action force is smaller than the defined pressure value, the air cylinder begins to retreat back, a spring is stretched, and pull force generated by the spring pulls the rectangular frame in the retreat direction of the air cylinder; meanwhile, a trolley begins to move in the direction close to the air cylinder on a guide rod, and tension force of the belt is restored through pulling of a traction line on the rectangular frame; and when the action force recorded by the pressure sensor is larger than the defined pressure value, the output end of the air cylinder stretches out in the direction opposite to the rectangular frame, the spring is compressed, and elastic force generated by deformation of the spring pushes the rectangular frame in the stretching-out direction of the air cylinder output end; and meanwhile, the trolley moves on the guide rod in the same direction as the air cylinder, pulling on the traction line is stopped, and the tension force of the belt is restored to be normal repeatedly.
