Intelligent yarn supply and automatic defect removing device of circular weft knitting machine

The invention relates to the technical field of textile machinery, and provides an intelligent yarn supply and automatic defect removing device of a circular weft knitting machine. The device comprises a rotary workbench, a yarn frame, an electronic yarn clearer for detecting yarn defects, a yarn sensor, a spare yarn cylinder, an air blowing yarn feeding mechanism, a telescopic push mechanism, a control system, a first traveling mechanism, a second traveling mechanism, a yarn splicer, a clamping mechanism, a rotary yarn pulling mechanism and a supporting frame. The device effectively solves the problems that traditional circular weft knitting machines can not effectively treat defect yarns or broken yarns detected, require manual connection, and are time-consuming, laborious and low in production efficiency, and yarn defects, broken yarns, artificial joints and other factors affecting fabric quality always exist. 本发明涉及纺织机械领域，提供种针织圆纬机智能供纱及纱线自动除疵装置，包括旋转工作台、纱架、检测纱线瑕疵的电子清纱器、纱线感应器、备用纱线筒、吹气送纱机构、伸缩推送机构、控制系统、第行走机构、第二
