Description

TECHNICAL FIELD

[0001] The utility model relates to an alumina fiber twisting and winding integrated equipment and belongs to the technical field of alumina fiber spinning equipment. BACKGROUND

[0002] Continuous alumina (Al2O3) fiber is one of the recognized new high-performance inorganic fibers, which has a series of excellent performance characteristics, such as high melting point, high hardness, corrosion resistance, good thermal insulation, etc. These properties make alumina fiber have a wide application prospect in high-temperature industrial equipment, aerospace, military, high-performance sports equipment, etc. In addition, alumina fiber also has good chemical stability and can be used in acidic environment, oxidizing atmosphere, reducing atmosphere and vacuum conditions. It also has certain corrosion resistance to alkaline environment.

[0003] During the twisting process of alumina fiber by the traditional twisting machine, due to the unevenness of mechanical action, when the yarn passes through the triangular area, the yarn is subjected to a large tensile and torsional force due to the twisting force. This mechanical action easily leads to uneven distribution of fibers inside the yarn and loose structure. Moreover, during the twisting process, the hairiness on the surface of the yarn is prone to increase, which not only affects the appearance of the yarn, but also increases the breakage rate during weaving, further affecting the quality and performance of the fabric. In addition, the traditional twisting machine often requires a large amount of manual operation, which not only increases the labor cost and operation difficulty, but also may lead to unstable production efficiency and quality due to human factors. The degree of intelligence is low, and there is a lack of advanced intelligent control system, making it difficult to realize the automation and intelligent management of the production process, which brings great difficulty to the improvement of the efficiency and energy consumption of alumina fiber production.

[0004] At present, the existing alumina fiber is twisted by a twisting machine. The single rope is first made by winding multiple wrapping wires on a core wire through the self-rotation of the twisting disc, and the multiple single ropes are twisted into a multi-strand rope by the self-rotation of the bottom disc driven by the self-rotation of the twisting disc. However, during actual work, the bottom disc may generate a certain amount of energy during the revolution due to speed changes or impacts, which may cause vibration and shaking between the bottom disc and the twisting disc, resulting in instability of the equipment deviation. In severe cases, it may cause the winding of alumina fiber. In addition, during the twisting process of alumina fiber, the equipment is often driven by a pure mechanical chain for winding, and the shelf driven by the motor realizes reciprocating traverse for winding. At this time, the yarn is subjected to a large tension, the alumina fiber itself has poor strength and is prone to brittle fracture, and the fiber is prone to breakage due to torsion during the twisting process, resulting in poor twisting effect and large damage to the yarn.
