Detailed Technical Features

Core Spinning Technology

• 
  

  Spin box heart of rotor spinning: Through comprehensive collection and analysis of experimental data, we optimize the channel of spin box to realize a perfect combination between optimal spinning and yarn quality. Equipped with patent trash-removal system, it can be sued to process a wider range of raw materials, allowing the customers to face the market changes more leisurely and reduce the labor intensity of workers. The opening of channel is embedded with high-strength ceramics, which can reduce the wear-and-tear of fiber to cavity and extend the service life.

• 
  

  Digital joint technology-guarantee of high speed spinning: Equipped with pneumatic lifting device as standard configuration, with broken end response time only 0.1 second. After millions of tests, it has high reliability. The unique joint system can store yarn after holding under the action of the roller and the guiding roller, so as to avoid the influence of the bobbin size on the joint quality. The special mathematical model of the joint and the step roller for sliver feeding and yarn guiding can precisely control the sliver feeding amount, sliver feeding time and yarn length to ensure the strength, shape and success rate of the joint. Under the same conditions, the strength of the joint is 10% higher than that of the original joint.

Automation & Efficiency

• 
  

  Automatic Doffing robots powerful automation ability: With powerful automation ability, the doffing, paper tube changing of rotor spinning are all replaced by manipulators, which further liberates labor force and takes a big step for the realization of automatic factory.

• 
  

  Collective joint System after power off: The system is mainly used for automatic joint under conditions of normal shutdown or abnormal grid power failure, which can reduce the joint time of the whole machine, reduce the labor intensity of worker.

System & Control Optimizations

• 
  

  Optimize the details to pursue perfection: Servo drives transverse yarn guiding, with the deliverying speed up to 300m/min. Stepping-driven inching mechanism to reduce the wear-and-tear of yarn to the roller. Optimized machine frame to reduce operating height, supporting can of 1200mm at most. Variable frequency drive of the whole machine to realize energy-saving effect. Separate independent transmission to reduce auxiliary time in production.

• 
  

  Health Internet System: Host program of machine can be upgraded online, support functions of online monitoring and early warning towards main transmission components, and clients can get the actual operation of equipment in real time at any places around the world.

• 
  

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

• 
  

  Electronic Tension System: The digital control mode can reduce the work of complicated mechanical adjustments. The user can adjust the tension coefficient directly on the screen of headstock, with the adjustment precision up to 0.001, which ensures stable forming of winding package.

• 
  

  Integrated control: Distributed control, fast response, intuitive signal, easy operation and maintenance.

• 
  

  Global Sourcing to Guarantee Quality: We carry out strategic cooperation with well-known suppliers (including VAN DE WIELE, EXTRUSION, LGL, ABB, STÄUBLI, Schneider Electric, OMRON, SIEMENS, Panasonic), with special components purchased via global sourcing to ensure equipment quality. Perfect and sound quality management system ensures product quality.

Maintenance & Design

• 
  

  Color Change of Whole Machine: The color system of machine is redesigned completely by Italian company. Compared with present design, the color system turns to be more abundant with a sense of layering, and brings new visual impact to user.

• 
  

  Rotor bearing assembly free device: The device reduces the labor intensity of maintenance work significantly, ensures the stability of space distance, and improves product consistency.
