Description

Gripper shuttle yarn picking rod with novel structure

Technical Field

The utility model belongs to the technical field of the projectile loom, specifically speaking especially relates to a projectile yarn picking rod of novel structure.

Background

Currently, the weft thread for gripper looms comes out of the weft accumulator and passes through the eye of the take-up lever before being thrown into the gripper of the loom, which grips the weft thread and is introduced into the warp of the loom. When the yarn picking rod acts to the high position, the gripper clamp of the weaving machine receives weft yarns, the bending angle of the yarns at the porcelain eye of the yarn picking rod is the largest, the arc angle in the structure of the porcelain eye is small (10 degrees), the porcelain eye and the contact surface of the yarns form contact similar to a right angle, the strength loss caused by the abrasion of the porcelain eye to the yarns is the largest, the strength of the weft yarns is only 80 percent of the low position of the yarn picking rod, the strength of the weft yarns at the position 40cm away from the side of the yarn picking rod after the weft yarns are thrown into a cloth surface is the lowest, and the one-time.

Disclosure of Invention

In order to solve the problem, the utility model discloses a projectile picking rod with a novel structure.

The utility model discloses a realize through following technical scheme:

the projectile shuttle yarn picking rod with the novel structure is characterized in that one end of the yarn picking rod is provided with a mounting hole, the other end of the yarn picking rod is provided with a through hole, a yarn picking ring is fixed in the through hole, the aperture of the upper side and the aperture of the lower side of the yarn picking ring are larger than the aperture of the middle of the yarn picking ring, and the shape of the upper side and the lower side of the yarn picking ring is a circular arc.

The material of the yarn picking ring is ceramic.

The arc is 90 degrees.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses make the woof reduce 15% through this strong loss of choosing the yarn ring under same state, 95% when the woof is powerful to reach choosing the yarn pole low level, reach the state of corresponding with other positions are powerful basically, improved a qualification rate.

Drawings

Fig. 1 is a schematic structural diagram of the present invention;

fig. 2 is a schematic cross-sectional view of the structure of the yarn picking ring of the utility model.

In the figure: 1. mounting holes; 2. a through hole; 3. a yarn picking ring; 4. a circular arc.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

as shown in fig. 1 and 2 of the attached drawings of the specification, the projectile picking rod with a novel structure is characterized in that one end of the picking rod is provided with a mounting hole 1, the other end of the picking rod is provided with a through hole 2, a picking ring 3 is fixed in the through hole 2, the aperture of the upper side and the aperture of the lower side of the picking ring 3 are larger than the aperture of the middle part, and the upper side and the lower side of the picking ring 3 are circular arcs 4.

The material of the yarn picking ring 3 is ceramic.

The arc 4 is 90 degrees.

When the yarn picking rod acts to a high position, the gripper clamp of the weaving machine receives weft yarns, the bending angle of the yarns at the porcelain eye of the yarn picking rod is the largest, and because the yarn picking ring is made of ceramic and the arc angle is 90 degrees, the strength loss of the weft yarns passing through the yarn picking ring under the same state is reduced by 15 percent (from 20 percent to 5 percent), the weft strength of the fabric and the uniformity of the weft strength of the whole fabric are improved, and the one-time qualified rate is improved.

In summary, the present invention is only a preferred embodiment, and is not intended to limit the scope of the present invention, and all equivalent changes and modifications of the shapes, structures, features and spirit described in the claims of the present invention should be included in the scope of the present invention.
