Background
Continuous alumina (Al 2O3) fiber is one of the accepted novel high-performance inorganic fibers, and has a series of excellent performance characteristics such as high melting point, high hardness, corrosion resistance, good heat insulation and the like. The performances enable the alumina fiber to have wide application prospects in the fields of high-temperature industrial equipment, aerospace, military industry, high-performance sports equipment and the like. In addition, the alumina fiber has good chemical stability, can be used in acid environment, oxidizing atmosphere, reducing atmosphere and vacuum condition, and has certain corrosion resistance to alkaline environment.
In the process of twisting the alumina fiber by the conventional twisting machine, the yarn passes through the triangular region due to the non-uniformity of the mechanical action, and is greatly stretched and twisted due to the action of the twisting force.

In addition, the traditional twisting machine often needs a large amount of manual operation, which not only increases labor cost and operation difficulty, but also possibly causes unstable production efficiency and quality due to human factors, has lower intelligent degree, lacks an advanced intelligent control system, and is difficult to realize automatic and intelligent management of the production process, thereby bringing great difficulty to the improvement of the production of alumina fiber in the aspects of efficiency, energy consumption and the like.

However, in the existing rope twisting machine, certain energy can be generated by speed change or impact of the chassis in the revolution process in the actual working process, and the energy can vibrate and shake between the chassis and the twisting disc, so that equipment deviation is unstable, and alumina fiber can be wound under severe conditions. In addition, in the twisting process of the alumina fiber, the pure mechanical chain drives equipment to roll, the motor-driven frame realizes reciprocating traverse to roll, at the moment, the tension born by the yarn is particularly high, the strength of the alumina fiber is poor, the alumina fiber is easy to brittle fracture, the fiber is easy to fracture due to torsion in the twisting process, the twisting effect is poor, and the damage to the yarn is large.
