Abstract:In order to further improve the performance of JWF1618 rotor spinning machine and ensure that the bobbin lifting device uses less material and is easy to process and assemble，the structure and processing technology of yarn bar connector are optimized according to the mechanical complexity-cost curve and the convenience of function realizing.Through the continuation of the original dynamic structure，the use of PLC solenoid valve control cylinder as the power source to achieve single spindle and single control，the original yarn bar connector turns into a single arm support，circular movement，welding fixed，using 45 steel，Q235A cold rolled steel as the supporting rod and the material of other parts，the structure of the supporting piece，technical plan and key points of technical documents of yarn bar connector are described in detail.By comparison with spinning tests，the yarn strength is stable and the average joint strength is 65%～75% of the original yarn strength.It is pointed out that the optimized yarn bar connector is easy to process and assemble，and increases the added value，which can reduce the cost and increase the efficiency for textile enterprises.
Key Words:rotor spinning machine；yarn bar connector；mechanical complexity-cost curve；bobbin；winding roller；yarn strength
