[0002] With the further development of the scale and industry of the domestic textile industry, the doubling twisting machines belonging to the textile industry are constantly being researched and updated. Among them, the single-spindle single-control doubling twisting machine has received increasing attention in the market. It is favored by more and more enterprises because of its lower unevenness rate of yarn twist, lower yarn waste, lower labor cost, and higher yarn quality. The twisting part of the spindle is an important part of the doubling twisting machine. However, due to the split design structure of the traditional doubling twisting machine, it needs to be refueled and maintained, which causes oil pollution to the yarn. Moreover, due to its structural design, it occupies a relatively high space occupancy rate, so it is not suitable for the single-spindle single-control doubling twisting machine.
