Abstract

A spiral yarn guide hook suitable for a ring spinning automatic connector is formed by combining a yarn guide eye spiral body and a yarn guide eye supporting rod, wherein the yarn guide eye spiral body is formed by spirally winding a section of metal strip, the diameter of the metal strip is 2-4 mm, the spiral direction of the metal strip is left-handed or right-handed, the spiral winding is 360-540 degrees to form a yarn guide eye, the upper metal strip and the lower metal strip which are spirally wound and overlapped on the circumference of the yarn guide eye are alternated by 1-3 mm to form a yarn threading channel, the yarn guide eye supporting rod and the yarn guide eye spiral body are fixedly connected in a T shape, and the fixed point is located on the outer circumference of the yarn guide eye.

Description

Spiral yarn guide hook suitable for ring spinning automatic joint

Technical Field

The invention relates to a yarn guide hook of spinning equipment, in particular to a spiral yarn guide hook suitable for automatic joint of ring spinning.

Background

The existing yarn guide hook for the ring spinning frame almost adopts a circular yarn guide eye formed by a metal spiral type, yarns can be wound into the yarn guide eye of the yarn guide hook along a spiral gap, the spiral yarn guide hook can stably enclose the yarns, the influence of twist-fall is reduced, the damage to the yarns is small, and the manufacture is simple; with the continuous progress of the spinning technology, people pay more and more attention to the ring spinning automatic joint technology, in the automatic joint technology, a plurality of technologies propose to adopt an intelligent manipulator to control a yarn to penetrate into a yarn guide eye, the manipulator simulates the operation of penetrating a yarn guide hook of a human hand, the motion trail is a multidimensional motion trail, the flexibility of the manipulator in the multidimensional direction and the flexible clamping requirement on the yarn are very high, at present, no equipment and manipulator are successfully researched and developed in China, the idea of adopting the manipulator to push the yarn into the yarn guide eye is proposed in the patent ZL201510420896.3 'ring spun yarn broken end automatic intelligent joint method and device', the concept can greatly simplify the motion trail of the automatic joint manipulator of a spinning frame, the complexity of the manipulator mechanism is reduced, and in order to realize the idea, the existing spiral structure yarn guide mechanism and the yarn penetrating mode are not applicable.

Disclosure of Invention

One object of the present invention is: the spiral type yarn guide hook is suitable for automatic ring spinning splicing and is used for simplifying the mechanism track complexity of an automatic ring spun yarn splicing machine.

A spiral yarn guide hook suitable for a ring spinning automatic connector is formed by combining a yarn guide eye spiral body and a yarn guide eye supporting rod, wherein the yarn guide eye spiral body is formed by spirally winding a section of metal strip, the diameter of the metal strip is 2-4 mm, the spiral direction of the metal strip is left-handed or right-handed, the spiral winding is 360-540 degrees to form a yarn guide eye, the upper metal strip and the lower metal strip which are spirally wound and overlapped on the circumference of the yarn guide eye are separated by 1-3 mm to form a yarn threading channel, the yarn guide eye supporting rod and the yarn guide eye spiral body are fixedly connected in a T shape, and the fixed connection point is located on the outer circumference of the yarn guide eye.

Furthermore, the surface of the spiral body of the thread eye of the spiral type thread guide hook is hardened and polished.

Furthermore, the bending directions of the two ends of the spiral body of the yarn guide eye are symmetrically opposite, and the shape structure is unchanged after the spiral yarn guide hook body is turned over for 180 degrees.

The invention has the beneficial effects that:

the spiral type yarn guide hook is formed by combining the yarn guide eye spiral body and the yarn guide eye supporting rod, the yarn guide eye supporting rod and the yarn guide eye spiral body are fixedly connected in a T shape, when the yarn guide hook is penetrated through in an automatic joint, the mechanical arm can control the yarn to be pushed into the yarn guide hook from a position vertical to the axis of the yarn guide eye, the mechanical motion track is greatly simplified, and the spiral type yarn guide hook has great practical value for low-cost popularization and application of an automatic joint technology of a spinning frame.

Drawings

FIG. 1 is a schematic view showing a structure of a screw type thread guide hook suitable for a ring spinning automatic joint according to the present invention;

FIG. 2 is a schematic view showing the structure of the other side of a spiral type yarn guide hook suitable for a ring spinning automatic joint according to the present invention

Detailed Description

The technical scheme of the invention is described in detail in the following with reference to the accompanying drawings. The examples of the present invention are provided only for illustrating the specific process, the scale of the process is not limited by the examples, and any modification based on the principle of the present invention and using the common general knowledge of the skilled person in the art is within the protection scope of the present invention.

Example one

As shown in fig. 1 and 2, a spiral type yarn guide hook suitable for ring spinning automatic joint, the spiral type yarn guide hook is composed of a yarn guide eye spiral body 11 and a yarn guide eye supporting rod 12, the yarn guide eye spiral body 11 is formed by spirally winding a section of metal strip with the diameter d of 2-4 mm, the spiral direction is left-handed or right-handed, the spiral winding forms the surrounding angle of the yarn guide eye to be 360-540 degrees, the spirally wound metal strip forms the yarn guide eye a of the yarn guide hook, the interval B between the upper metal strip and the lower metal strip which are spirally wound and overlapped on the circumference of the yarn guide eye a is 1-3 mm, the gap of the interval B is a channel for the yarn to enter the yarn guide eye, the yarn guide eye supporting rod 12 is fixedly connected with the yarn guide eye spiral body 11 in a T shape, the point is fixedly connected on the outer circumference of the yarn guide eye, when the automatic joint machine threads the yarn through the yarn guide hook, a mechanical hand controls the yarn Y to be vertical to the axis O of the yarn guide eye, according to the arrow direction shown in the figure, the yarn is pushed in linearly from the gap with the distance B, when the yarn Y returns to the axis O direction of the yarn guide eye, the yarn is positioned in the yarn guide eye, after the spiral winding of the metal strip of the spiral body 11 of the yarn guide eye is completed, two ends of the metal strip are bent towards the spiral angle rising direction, the bending directions of the two ends are symmetrically reversed, the spiral type yarn guide hook is installed by turning 180 degrees, and the shape structure is unchanged.
