Description

Technical field [0001] The present invention relates to the technical field of spinning equipment, in particular to a double-air rotor spinning machine. Background technique [0002] Rotor spinning is one of the new spinning technologies. Compared with traditional spinning technology, it has the characteristics of short process, high efficiency, high quality, and labor saving. It is the focus of spinning technology transformation in my country in the future. The rotor spinning machines in the prior art are divided into two types: self-exhaust type and suction type. The negative pressure airflow required for spinning by self-venting rotor spinning machine is generated by the rotation of the perforated rotor. The airflow flows from the mouth of the rotor to the bottom of the cup. Although the rotor has a large diameter and simple structure, the negative pressure inside the rotor The pressure level has a lot to do with the speed of the rotor speed, so a certain rotor speed must be ...

AI Technical Summary

Problems solved by technology

The negative pressure airflow required for spinning on the self-exhausting rotor spinning machine is generated by the rotation of the perforated rotor, and the airflow flows from the mouth of the rotor to the bottom of the cup. Although the diameter of the rotor is large and the structure is simple, the negative pressure inside the rotor The pressure level has a lot to do with the speed of the rotor speed, so a certain rotor speed must be ensured; dust and impurities are easy to accumulate in the condensate groove of the rotor; lint is easy to accumulate around the exhaust hole of the rotor, thereby reducing the Negative pressure

The negative pressure airflow required for spinning on the air suction rotor spinning machine is generated by the suction of the centrifugal fan, and the airflow flows from the bottom of the cup to the mouth of the cup. Due to the different structures of the two rotors, the direction of the airflow in the rotor is also different. The styles are quite different. Although the negative pressure is stable and consistent, it can avoid dust and impurities from accumulating in the condensate tank, and the end-break rate is low, but the yarn produced has high twist, hard hand feeling, high maintenance requirements, and low impurity content in raw materials.
