The tension of warp and weft run through the whole weaving process in knitted carpet weaving equipment. The performance of delivering warp mechanism and guiding weft mechanism in this kind of equipment influences the quality of carpet directly. A self-adjusting delivering warp mechanism is designed in this thesis, which is used in knitted carpet weaving equipment or other textile equipment that delivers warp by warp-spindle and demands even warp tension. The self-adjusting delivering warp mechanism consists of the device for setting and detecting warp tension, the device for driving warp-spindle in different speed, and the device for transmitting warp-spindle movement. The device for setting and detecting warp tension can determine initialization tension of warp, according to the technical requirements, can detect and feed back warp tension in real time. The device for driving warp-spindle in different speed makes the rotating speed of warp-spindle change according to the warp tension. The self-adjusting delivering warp mechanism realizes the function on controlling the rotating speed of warp-spindle in closed loop, and on stabilizing delivering warp tension.
