The invention relates to the field of
textile machinery, and provides an intelligent detection defect removal device for yarns of a circular weft knitting
machine. The intelligent detection defect removal device comprises a rotary worktable, a creel, an electronic
yarn clearer for detecting defects of the yarns, a plurality of electromagnetic valves, a PLC (
programmable logic controller), a firsttravel mechanism, a second travel mechanism, a
yarn splicer, a clamping mechanism, a rotary
yarn pulling mechanism, a support, an industrial camera and a dust removal mechanism. The rotary yarn pulling mechanism is arranged on the support, the upper-section yarns at defect positions, which are used as fixed points, of the clamped yarns can be rotationally downwardly pulled by the rotary yarn pulling mechanism, the upper-section yarns and the lower-section yarns at defect positions of the yarns can cross one another by the aid of the rotary yarn pulling mechanism to form crosses, the yarn splicer can slide on the support in the horizontal direction via the second travel mechanism, a yarn splicing opening of the yarn splicer directly faces the crossed yarns which form the crosses, and the yarns can be shorn and spliced by the yarn splicing opening. The intelligent detection defect removal device has the
advantage that the problems of incapability of effectively
processing yarns with defects detected by existing circular weft knitting machines, time and labor wastage during manual splicing, low production efficiency and influence on the quality of
textile fabrics due to factors such as the constant availability of yarn defects and manual connectors can be effectively solved by the aid of the intelligent detection defect removal device.
