Twisting device

Technical Field

The utility model relates to a twisting device.

Background

When a fabric is woven from yarns, the yarns need to be twisted in order to fix two or more single yarns into a folded yarn and obtain good quality states such as forming and strength, and the twisting is a necessary means for making a fiber strip into a yarn.

In the prior art, twisting is generally realized by a steel collar, which is a steel circular ring-shaped machine part playing a role in twisting and winding in spinning machines such as spinning frames, roving frames, twisting machines and the like. The steel ring has its edge projected out, and during spinning, the yarn drives the steel ring to rotate on the steel ring track. The wire loop makes one turn, and the yarn is twisted. The steel wire ring is generally a small ring with a gap formed by bending a steel wire. It is close to the inner side of the ring runway and slides due to the action of centrifugal force when rotating on the ring. Because the relative speed of the steel wire ring and the steel collar is very high, abrasion and high temperature (above 300 ℃) are generated due to friction, so that the steel wire ring is broken off, burnt or unstable in rotation, and the yarn is broken. Therefore, the combination of the ring and the traveler is required to be capable of high-speed operation with less breakage and to extend the life of the ring. The main operational performance of rings and travelers is often expressed in terms of the linear speed that can be achieved during normal spinning. With the development of the technology, the running speed of the steel wire ring is improved to be more than 40 m/s. However, with the increasing demand for production, how to further increase the output of single ingot becomes one of the research directions in recent years, wherein the increase of the rotation speed of the front roller is one of the important indexes, and the increase of the rotation speed of the front roller in the prior art needs to increase the ingot speed, which is limited by the angular speed of the steel wire ring.

In the prior art, the angular speed of a steel wire ring is improved by reducing the size of a steel collar, but the size of a bobbin is limited. And the design of rotating the steel ring is also provided, so that when the angular speed of the steel wire ring is increased, the relative speed of the steel wire ring and the steel ring cannot be increased, and the reduction of the service life of the steel wire ring caused by the increase of the running speed of the steel wire ring is avoided. However, in the prior art, the rotary ring is generally in a transmission design, and a transmission belt and other structures are required to be arranged, so that the rotary ring is easy to wear and has a short service life; the design of using a ball bearing and a dynamic pressure air bearing to realize the rotation of the steel collar is also available, but the structure is very complex, the failure is easy to occur, the installation and the maintenance are complex, and the steel collar is not suitable for popularization and use.
