AI Technical Summary
The existing twisting machines are prone to tension unstable during the twisting process, resulting in broken yarns, and the yarn is not replaced in time after the yarn is used up, resulting in the yarn continuing to transport the winding roller to produce waste yarn, which increases labor intensity and waste of raw materials. Infrared yarn breaking sensors are costly and are susceptible to external light sources.
A pneumatic large twister is designed, which uses a yarn breaking probe rod and a pressure sensor. The probe rod monitors pressure changes when the yarn is broken, controls the cylinder to drive the rocker to rise, stops the yarn transport, and avoids wrapping the roller.
It effectively avoids the generation of waste yarn caused by continued transportation of yarn, reduces labor intensity and waste of raw materials, and is low in cost and is not easily affected by external light sources.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of textile equipment, and in particular relates to a pneumatic large double twisting machine. Background Art
[0002] The twisting system is a general term for equipment that adds twist to staple yarn, silk (silk), and chemical fiber filament. The core equipment is various two-for-one twisters. The front of the two-for-one twister is a device for changing the package or merging multiple strands of single yarn. It is a supporting equipment for the two-for-one twister. During the operation of the twisting machine, the tension is unstable and the yarn breaks occasionally, or the yarn is not replaced in time after it is used up. Since the machine is not stopped in time, the yarn will continue to be transported and then entangled with the roller, resulting in waste yarn. Not only is the raw material wasted, but it also needs to be manually removed, which increases the labor intensity. Therefore, it is particularly important to equip a set of effective yarn break protection devices. At present, there are infrared yarn break sensors on the market that can solve this problem well. However, equipping infrared sensors is not only costly, but also easily affected by flying cotton and external light sources, resulting in false stops, thereby affecting the production efficiency of the twisting machine.

[0014] The principle of the utility model is as follows: first, the untwisted yarn bobbin is sleeved on the spindle 6, and the end bobbin of the yarn is inserted into the multi-stage tensioner 7 and passed out from the bottom of the spindle 6.
