Problems solved by technology

[0003] The main problems are: (1) the outer leg of the traveler collides with the outer runway of the steel ring instantly, which is easy to cause broken ends; (2) the contact length between the existing steel ring and the traveler is limited, and the contact length of the flat steel ring is only 1.5-2.5mm, and the contact length of the tapered steel ring is only 3-5mm, so that the traveler wears seriously, the service life is short, and the traveler needs to be replaced frequently. At the same time, the temperature of the traveler is high, which is easy to damage the fiber and affect spinning Quality; (3) The traveler is only in contact with the inner track of the steel ring, and the high-speed operation of the traveler on the steel ring is prone to frequent shaking or swinging, resulting in more yarn end breakage, hairiness, and neps.

Embodiment 1

[0025] like figure 1 The lower supporting ring 1 shown is provided with an inner runway 1a and an outer runway 1b, the angle between the inner runway 1a and the horizontal coordinate axis is α1, and α1=65~89°, which constitutes the lower supporting tapered steel ring , in the cone ring, when the angle between the inner runway 1a and the horizontal coordinate axis is less than 65°, it is the upper support cone ring; when the angle between the inner runway 1a and the horizontal coordinate axis is greater than 65°, it is the lower support For the support cone ring, 65° is the dividing point between the upper and lower support cone rings. As the lower supporting ring, during normal spinning, the matching lower supporting traveler is under the upward force F and is in the lifting operation state; on the contrary, when the upper supporting ring is normally spinning, the supporting upper supporting traveler is under the upward force F The downward force F is in the pull-down operat...

Embodiment 2

[0031] like Figure 4-6 As shown, the lower support ring 1 and the lower support traveler 2 are basically similar to the embodiment 1, and the difference from the embodiment 1 is that the inner track 1a is an arc surface, and the radius of the arc is R2, R2=4~20mm, The angle between the inner runway 1a and the horizontal coordinate axis is α1, which is the angle between the chord of the arc and the horizontal coordinate axis.

[0032] like image 3 , in the size design of the lower support ring 1, the side width B1=2.4~4mm, preferably 3.2mm; the width of the top protrusion B2=0.5~2mm, preferably 1.2mm; the radius of the top protrusion R1=0.2~1mm , preferably 0.5mm; the depth of the top outer depression h1=1~3mm, preferably 1.4mm; the inclination angle of the bottom slope of the top depression α2=5°~20°, preferably 10°; the inclination angle of the inner slope of the top depression α3=5° ~20°, preferably 10°; the minimum wall thickness of the ring h2=0.5~1.5mm, the inner trac...

Abstract

The invention discloses a combined structure of a lower support double-runway conical ring and a steel wire ring, wherein an included angle alpha 1 between the inner runway (1a) of a lower support ring (1) and a horizontal coordinate axis is equal to 65-89 degrees; a dent with a depth of h1 is arranged on the outer side of the top of the lower support ring (1); the outer end of the dent is lower than the inner end of the dent so that an inclined surface with an inclined angle alpha 2 is formed; when yarns (3) run normally on the lower support ring (1) along with a lower support steel wire ring (2), the lower support steel wire ring (2) is at a lifting running state by means of an acting force of F; and simultaneously, the ab segment inner leg of the lower support steel wire ring (2) is tightly attached to the inner runway (1a) of the lower support ring (1) together, and the cd segment outer leg of the lower support steel wire ring (2) is tightly attached to the outer runway (1b) of the lower support ring (1) together. Through the structure, the contact area between the ring and the steel wire ring is increased, stable movement of the steel wire ring on the ring is ensured, the service life of the steel wire ring is prolonged, broken ends are reduced, and the spinning quality is improved.

Description

technical field [0001] The invention relates to components on textile equipment, in particular to a combined structure of a lower-support double track cone steel ring and a steel traveler. Background technique [0002] At present, in the design and manufacture of steel rings for cotton spinning equipment, there are flat steel rings and conical surface steel rings, and the conical surface steel rings are divided into upper support conical surface steel rings and lower support conical surface steel rings. The steel ring is a ring, whether it is a flat steel ring or a tapered steel ring, the inner runway is designed as the main runway. Figure 7 Shown is the combined structure of the plane steel ring and the traveler. During normal spinning, the yarn 3 rotates on the steel ring 1 with the traveler 2 at high speed, and the centrifugal force generated makes the traveler 2 close to the inside of the steel ring 1. Running on the runway 1a, while the traveler 2 is suspended on the o...
