RFRS30D Rotor Spinning Machinery Details

spinner-heart-of-the-rotor-spinning-machine.png

  • Spinner----Heart of The Rotor Spinning Machine

    It fully collects and analyzes the experimental data,  optimizes the channel of spinner to realize a perfect combination between optimal spinning and yarn quality; With the patent trash-removal system and it can process more raw materials of different kinds, making the customers face the market changes at a leisurely pace and reducing the labor intensity of workers; The opening of channel is covered with ceramics of high strength, reducing the wear-and-tear of fiber to cavity and prolonging the service life‘’

    Optimal_Joint_System.png

  • Optimal Joint System--The Promise Of High-Speed Spinning

    The standard pneumatic lifting device whose breaking response is 0.1 sec only; millions of experiments have proved it has high reliability. With the unique joint system, the roller is prior to the winding roller to guide the yarn when jointing to avoid the influence of bobbin to the quality of the joint. The exclusive mathematic jointing mode and stepping roller feeding accurately control the feeding volume and time to ensure the strength and shape of joint.

    color-change-of-whole-machine.png

  • Color Change of Whole Machine

    Beginning of intelligent, it starts the mode of semiautomatic machine to instead of labor work, to realize automatic doffing with no break ends, to reduce labor intensity. High efficiency, from fixed position to doffing, one standard doffing working time is within 20s. Intelligent, can realize automatic and manual mode of doffing.

    Rotor_Bearing__Free_Disassembly_Device.png

  • Rotor Bearing  Free Disassembly Device

    The device greatly reduces the labor intensity of the maintenance work, ensures the grid distance stability, and improves product consistency.

    Synchro_Piecing.png

  • Synchro Piecing

    The system is mainly used for automatic joint of normal shutdown or abnormal grid power failure, which can reduce the piecing time of the whole machine, reduce the labor intensity of the  worker.

Health_Internet_System.png

  • Health Internet System

    Program of machine can be upgraded online, online monitoring and early warning of th main transmission components, and user can know the actual operation of equipment in real time around the world.


    Electronic_Tension_System.png

  • Electronic Tension System
    The digital control can reduce the complicated mechanical adjustment work. The user can directly adjust the tension coefficient in the monitor of headstock, and the adjustment precision can reach 0.001, which ensures the stable forming for winding package.




Barotropic_Cooling_System.png

  • Barotropic Cooling System

    The system can reduce the accumulation of flying and dust in the inner cavity of headstock and tail box, reduce the laborintensity of maintenance workers, improve the heat cooling condition of electrical components, and thereby increase the operation stability and reduce energy consumption.


    Automatic_Take_Out_Impurity_System.png

  • Automatic Take Out Impurity System

    The system will reduce the labor intensity of the operator, and also provide a more stable negative pressure environment for the machine, which makes spinning production more stable and improves the consistency of the yarn quality.




Color_Change_of_Whole_Machine.png

  • Color Change of Whole Machine
    The color of machine was completely by the ltalian company.

    The color will be plentiful and more layered than now, and it will bring new visual impact to user.


    Optimize_The_Details_To_Be_Perfect.png

  • Optimize The Details To Be Perfect

    ○ Servo drives transverse yarn guiding and the deliverys speed can reach up to 200 m/min;

    ○ The stepping micro-drive organs reduce the wear-and-tear of yarn to the roller;

    ○ The optimized machine frame reduces the operating height and can be equipped with the can of 1200mm at most;

    ○ The whole machine is driven with converse frequency, reserving the energy and reducing consumption;  The two sides are transmitted independently  which decreases the production assistance time of production.

    Global_Sourcing_to_Guarantee_Quality.png

  • Global Sourcing to Guarantee Quality

    We carry out strategic cooperation with well-known suppliers, with special components purchased via global sourcing to ensure equipment quality. Perfect and sound quality management system  ensures product quality.
