The working principle of the rotary spinning machine is mainly based on the high-speed rotation of the rotary cup and the negative pressure inside the cup to complete the process of fiber transportation, coagulation, merging, and double twisting into yarn. The following is a detailed explanation of the working principle:
Overview of Working Principle
Fiber transportation: Fiber raw materials (such as cotton, wool, linen, silk, synthetic fibers, etc.) are pre treated and transported to the combing area of the rotary spinning machine through a feeding mechanism.
Combing into single fibers: Under the action of the combing roller, the strips are combed into single fibers. These single fibers are ready to be further processed into yarn.
Fiber coagulation and coalescence: Due to the centrifugal force generated by the high-speed rotation of the rotor or the suction effect of the fan, a certain negative pressure is formed inside the rotor. This negative pressure forces the single fibers decomposed by the combing roller to be sucked into the spinning cup and slide into the coagulation groove on the cup wall to form coagulation strands.
Twisted into yarn: When the yarn is led through the yarn guide tube, it is also sucked into the coagulation groove and connected to the formed strands. Under the friction grip of the spinning cup, the fibers are twisted into yarn.
Yarn extraction and winding: The yarn is extracted from the spinning cup by the yarn guide roller, passed through the false twisting disc and yarn guide tube, and finally wound into a tube by the rotation of the winding roller (groove tube).
Technical features and advantages
High spinning speed: The rotor spinning machine achieves high-speed spinning through the high-speed rotating rotor and optimized airflow system, greatly improving production efficiency.
Short process flow: Compared with traditional ring spinning, rotor spinning eliminates some twisting and winding components, simplifies the process flow, and reduces production costs.
Wide applicability of raw materials: Rotary spinning machines are widely used for spinning various raw materials such as cotton, wool, linen, silk, and synthetic fibers, with high flexibility and adaptability.
High degree of automation: Modern rotor spinning machines are equipped with advanced technologies such as automatic joint devices, automatic winding, single spindle single control, and electronic yarn clearer, achieving efficient and intelligent production.
Development Trends
High speed: With the continuous advancement of technology, the speed of rotor spinning machines is constantly increasing to further improve spinning efficiency.
High yield: By optimizing the design and increasing the number of equipment heads, the output of the rotor spinning machine has been significantly improved.
Intelligence: The application of intelligent technology enables the rotor spinning machine to achieve more precise control and more efficient operation.
Energy conservation and environmental protection: Pay attention to energy conservation, consumption reduction, and environmental protection requirements in the design and production process, and promote the sustainable development of the textile industry.
In summary, the working principle of the rotor spinning machine is based on the high-speed rotation of the rotor and the negative pressure effect to achieve the process of fiber transportation, coagulation, merging, and double twisting into yarn. Its technical characteristics and advantages make rotor spinning machines have broad application prospects and development space in the textile industry.
