Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rotating spinning ring designed to prevent the ingress of dust.

Traditionally, in order to increase the speed of spinning machine spindles,
Rotating rings have been considered in which the circumference of the ring is held by a bearing, or the ring is actively driven by a belt or a sliding wheel. However, in all rotating rings with the above configuration, there is always a gap between the ring holder part and the ring rotating part, so dust such as floating fibers and fine powder enters through this gap and accumulates on the sliding surface of the ring. This obstructs the rotational movement of. For this reason, there is a drawback that tension inconsistency occurs between the spindles of the spinning machine, resulting in an increase in thread breakage or inhibiting the rotation of the ring from increasing, thereby deteriorating the function of the rotating ring.

The present invention has been made to eliminate the above-mentioned drawbacks, and one embodiment thereof will be described below with reference to the drawings.

As shown in FIGS. 1 and 2, the rotating ring is composed of a ring rotating body 1, a ring support portion including a sliding body 2, a bearing 3, etc., and a holder 4.

The ring rotating body 1 has a ring flange 5 at the top, and a collar 6 is integrally formed on the outer periphery of the upper part. The flange 6 is provided with a plurality of grooves 7 carved at equal intervals on its outer periphery, or a plurality of blades fixed integrally at equal intervals. Further, on the lower end surface of the ring rotating body 1, a plurality of diagonal grooves 8 having an inclination of 30 to 60 degrees with respect to the tangent line are carved at equal intervals, or a plurality of blades are cut diagonally at equal intervals. They are arranged and fixed together.

As shown in FIG. Alternatively, as shown in FIG. 1B, it is rotatably supported by a holder 4 via a bearing 3 to form a rotating ring for spinning.

Since the rotating ring for spinning of the present invention has the above-mentioned configuration, the ring rotating body is rotated by the traveler that rotates while engaging with the ring flange, and as a result of the rotation, the ring rotating body is formed on the brim and lower end surface of the ring rotating body. The grooves and diagonal grooves generate airflow in the radial direction of the ring.

Dust floating around the ring is blown away by the air flow, and dust is prevented from entering the gap between the ring rotating body and the holder. As a result, there is no dust adhering to the ring sliding surface, and stable ring rotation can be achieved.The spindle can rotate at high speeds, resulting in high production, as well as producing high-quality yarn with less yarn breakage and yarn fuzz. It has the excellent effect of being able to be produced.
