Air bag tension system for warp knitting and weaving high-count staple yarns

The invention provides an air bag tension system for warp knitting and weaving high-count staple yarns. With the help of the air bag tension system, wave power is transmitted to a shaft lever structure in the reverse direction of a yarn path, a shaft lever mechanism is forced and sends swinging, a lever principle is used, the wave power is transmitted to an air bag through a pressing lever, the air bag effectively absorbs vibration waves through internally-stored gas, and the fluctuation of tension is made up. The air bag is a constant tension air bag, a tension value can be preset according to the machine speed, material difference, yarn head lines and thicknesses of yarns, if a pressure sensor senses the tension of the air bag is excessive, a control system enables an air-supply device to perform return air (air deflation) on the air bag through an air opening, and if not, the air bag is inflated. According to the air bag tension system for warp knitting and weaving the high-count staple yarns, the problem
