Intelligent flat knitting machine system, because of intellectual property protection reasons, only show part of the sand nozzle motor and roller motor. In the finished flat knitting machine system, there are 200 closed-loop integrated stepper motors in the sand nozzle part and one closed-loop integrated stepper motor in the roller part. Compared with the traditional flat knitting machine, which share a motor as the power system, it not only greatly improves the efficiency of flat knitting machine, but also provides a revolutionary motion control system for the upgrading of Intelligent Manufacturing in the textile industry, which makes it possible to customize and personalize the textile industry.
