(Because the former POY and FDY production lines of the former spinning machine are not conducive to the development of new products because one frequency converter controls the six position winding heads. Through the development of the mobile experimental position, the "centralized" speed regulation of the six position winding heads is changed to the independent control of the winding heads at any position of the production line. The control cabinet can be moved, including three frequency converters to achieve the speed regulation of the three motors of the conflict roll, slot roll and chuck, and one PLC to achieve the logic control function)
