The working principle of the new rotor spinning machine
 日期:2025/4/30 9:48:00 

The working principle of the new rotor spinning machine is based on free end spinning technology, which completes fiber combing, coagulation, and twisting through high-speed rotating rotors, combing rollers, and airflow conveying systems. Its core process and technical characteristics are as follows:

1、 Core workflow

After the fiber combing and conveying cotton strips are held by the feeding roller and feeding plate, they are opened into single fibers by the high-speed rotation (speed 5000-9000 revolutions per minute) of the combing roller covered with metal needle cloth on the surface.

The fibers enter the rotor through the conveying channel with the airflow, and are conveyed under the combined action of the centrifugal force of the combing roller and the supplementary airflow.

The high-speed rotation of the fiber coagulation and twisting rotary cup (with a speed of up to 150000 revolutions per minute) generates centrifugal force, causing the fibers to slide along the cup wall into the coagulation groove and form circular whiskers.

The anti twist disc applies false twist to the yarn strip through friction, increasing the twist of the yarn strip at the peeling point and improving the connection strength between the whisker strip and the seed yarn.

The yarn guide roller holds one end of the seed yarn, and the rotating cup drives the silk strands to rotate at high speed to complete twisting. The yarn is then wound into a tube by the winding roller.

2、 Key technical features

Airflow field and negative pressure system suction type rotary cup: Negative pressure is generated at the gap between the top of the rotary cup and the lid by an external fan, and the airflow is discharged from the exhaust hole through the isolation disk guide groove to ensure stable fiber transportation.

Self exhaust rotor: The rotor opening design utilizes high-speed rotation to generate centrifugal force for exhaust, resulting in low equipment cost and low power consumption. However, the rotor speed needs to be controlled between 50000 to 70000 revolutions per minute to maintain negative pressure stability.

Optimization of spinner structure: The spinner integrates feeding, combing, impurity removal, stretching, twisting, and self stopping devices. It adopts a three-axis parallel layout to simplify the transmission mechanism, making it easy to disassemble and repair quickly.

The magnetic levitation rotor motor technology reduces mechanical friction, increases the speed to 150000 revolutions per minute, reduces energy consumption, and increases production capacity.

The intelligent control system is equipped with barcode tube control, cloud platform technology, and LED stop worker guidance system to achieve digital management of the production process.

The success rate of automatic joint technology reaches over 60 spindles for synchronous operation, reducing manual intervention and optimizing the operating experience.

3、 Technical advantages and application scenarios

The high-efficiency and energy-saving double-sided process suction system reduces the energy consumption per ton of yarn, and the magnetic levitation motor and independent drive technology reduce transmission losses, achieving energy savings of up to 10%.

The collective head production system shortens the overall machine connection time and improves production efficiency.

Diversified single spindle independent control technology enables the simultaneous spinning of multiple varieties of yarn, meeting the market's demand for rapid response.

The proprietary digital joint model ensures joint strength, shape, and success rate, and is suitable for rough style products such as denim fabrics.

Three environmentally sustainable collection box systems classify and recycle fibers, upgraded yarn guide nozzles reduce flying flowers, dust, and impurities, and extend cleaning intervals.

The host program supports online monitoring, warning, and upgrading, reducing maintenance costs and improving device stability.
