What are the advantages and disadvantages in the use of asymmetric travelers and ordinary travelers?
Many people have misunderstandings or do not understand “What are the advantages and disadvantages of asymmetric travelers and ordinary travelers?“. Next, let the editor take you to have a discussion with all your friends. Share and explore knowledge about “The advantages and disadvantages of asymmetric travelers and ordinary travelers during use?“…
There are many ways to classify travellers. If classified according to the presence or absence of a symmetrical centerline method (the vertical line drawn at the midpoint of the line connecting the two legs of the traveler can be understood as the symmetrical centerline of the traveler), it can be divided into Symmetrical travelers and asymmetrical travelers.
There are many types of symmetrical wire rings, such as 6903 type, FO type, G type, OSS type, 2.5W type, W321 type, EL type, EW type, EM type, MM type and UM type, etc., and PG1 type, PG1/2 type and PG2 type three types of flat steel rings are used together and are widely used in the matching needs of various spinning technologies such as compact spinning, siro spinning, core spinning, and color spinning.
There are three main types of asymmetric travellers: BC6, BC9 and PG12. They are all products that have obtained national patents. Among them, BC series tapered wire rings such as BC6 type and BC9 type are specially developed and produced in conjunction with BC series tapered wire rings such as BC6 type, BC7 type and BC9 type. They are widely used in chemical fibers, blended chemical fiber fabrics, silk Spinning fibers are widely used by customers in Fujian, Jiangxi, Zhejiang, Jiangsu, Hubei and other places. Its superior spinning performance has been specially introduced in many materials and will not be described here. Here we focus on the PG12 asymmetric traveler, which has obtained the national invention patent. It is used in conjunction with the PG1 flat steel ring.
The PG12 asymmetric traveler is designed according to the spinning tension characteristics and has a unique asymmetric geometry and asymmetric track. The contact area of the PG12 type traveler and the PG1 type flat steel ring during the spinning process of the ring spinning machine is 2 to 3 times that of the general symmetrical traveler and the PG1 type flat steel ring. Therefore, when spinning chemical fibers and blended chemical fibers When weaving fibers, the yarn quality is particularly good. Under the same conditions, the service life of the PG12 type traveler is 1-2 times longer than that of the symmetrical type traveler. Its main spinning characteristics are as follows:
, the contact area between the steel ring and the traveler is large, and the pressure per unit area is small, which prolongs the service life of the traveler; secondly, the spinning channel formed by the steel ring and the traveler is large, and has better dynamics during the twisting process Stability, the steel ring has good anti-wedge performance; third, the spinning yarn tension fluctuation is small during the spinning process, and the stability is good, which is beneficial to reducing the breakage of the spinning yarn; the package characteristics are good, which is conducive to the realization of large packages; third Fourth, when the traveler is running at high speed on the steel ring, due to the large contact area between the steel ring and the traveler, the heat dissipation is fast, so the temperature of the working surface is low, and the fibers will not be damaged during spinning, which is beneficial to improving the quality of the yarn, and is very suitable. Chemical fiber and blended chemical fiber fabric fibers; fifth, the traveler has good adaptability to temperature and humidity changes in the spinning environment; sixth, due to the special asymmetric geometric structure of the PG12 traveler, the traveler is embedded with steel There is a directional choice in the leading track, that is, the end with the curved legs and the long tail must be on the inner track of the steel ring, otherwise, the traveler cannot operate normally on the steel ring; therefore, under the same conditions, the time for the PG12 type traveler to be embedded in the steel ring A little more than the symmetrical traveler, which is the fly in the ointment.
