PU synchronous belt intelligent control, multi-channel photoelectric sensor safety automatic stop device, improves the automation level of production and the safety of the workers operation. Using high xiao motor and dc bus control scheme of variable frequency motor synchronous operation of high precision and satisfies the requirement of spinning technology; Ensure flyer speed 1500 r/min, the machine power consumption is less than 10 kw, energy saving effect is obvious. Touch screen man-machine dialogue, process parameters of intelligent configuration, roving tension adjustment using full digital sectional control system, has made great variety, the adjustment of the roving tension under different conditions. Also has the function of fault diagnosis, maintenance easy to use. Due to the synchronous belt is working the tooth, tooth load distribution is not uniform has a great influence on the life of the synchronous belt, and brought to the attention of the scholars around the world, has now been published related research paper with synchronous belt transmission, represents a significant share of the content, including Switzerland, G. Jie times, Japan's rich husband, hill, outline the zhen male, the Soviet union's column has high feed, but. . . , all with load distribution among gear teeth has carried on the theoretical and experimental research.
