Background

Along with the continuous development of the textile industry, the application of the hank reeling machine is more and more extensive, and the hank reeling machine is convenient to operate and high in working efficiency, so that the production cost can be greatly reduced.

The reeling machine is a machine for winding bobbin yarn on a rotary yarn frame to form a hank, the existing reeling machine generally comprises a frame, the rotary yarn frame rotationally connected to the frame, a motor or a rocking handle and the like for driving the rotary yarn frame to rotate, and the bobbin yarn is wound on the rotary yarn frame for a certain number of turns to form a hank. After the skein is finished, yarn knotting operation is needed, the traditional yarn knotting device clamps the yarn through a clamping hook head with scissors to rotate to form a loop, and then the scissors cut the tail yarn to form knots. Although the mechanism is simple, the hook head is small, and the opening angle of the hook head clamp and the scissors cannot be too large, so the mechanism is not suitable for knotting thick yarns and multi-strand yarns. And because the looping ratio is small, the tail yarn is not easy to pass through the loop, and the knotting reliability is not high.

Detailed Description

The invention is described in detail below with reference to the figures and specific embodiments.

As shown in fig. 1, a knotting device for an automatic hank reeling machine comprises a knotting head 1, a thread hook 2, a knocking-over push rod 3, a knocking-over rocker 4, a thread shifting rocker 5, scissors 6, an upper baffle 8 and a lower baffle 7, wherein the knotting head 1, the thread hook 2 and the knocking-over push rod 3 are mutually matched, the knotting head 1 and the knocking-over push rod 3 are rotatably arranged relative to the thread hook 2, the knotting head 1 and the thread hook 2 are telescopically arranged relative to the knocking-over push rod 3, the thread shifting rocker 5, the scissors 6 and the upper baffle 8 are arranged above the knotting head 1, the thread hook 2 and the knocking-over push rod 3, and the knocking-over rocker 4 and the lower baffle 7 are arranged below the knotting head 1, the thread hook 2 and the knocking-over push rod 3.

In this embodiment, the pivot section of knot tying head 1 is installed in the sliding sleeve, and it can be at the sliding sleeve internal rotation with flexible slip, the knockover push rod 3 is installed on the pivot section of knot tying head 1 through the spout to follow knot tying head 1 and rotate together, and the rotatable block design of the other end of knockover push rod 3 simultaneously can not follow knot tying head 1 concertina movement when knot tying head 1 stretches out and draws back and slides together. In addition, the rotating shaft section of the knotting head 1 is of an inner hollow structure, the wire hook 2 is telescopically arranged in the rotating shaft, and the wire hook 2 faces to one side of the arranged binding wire, such as the wire hook 2 to the right in fig. 1 and the wire hook 2 to the inner side in fig. 2.

In this embodiment, the knotting head 1 is an "L" shaped structure, and the knotting thread at the end of the knotting head is inclined inward and becomes thinner, so that the thread can be unhooked at the later stage. The wire shifting rocker 5 is rotatably arranged below the upper baffle 8, and the end part of the wire shifting rocker is provided with an elbow convenient for wire shifting. The knot-removing rocker 4 is rotatably arranged above the lower baffle 7, and the end part of the knot-removing rocker is provided with an elbow convenient for thread removal. The outer side end faces of the upper baffle plate 8 and the lower baffle plate 7 are in V-shaped structures, and therefore the stranded wires can be gathered conveniently.

The working process of the device is as follows: firstly, the plurality of binding strands 9 can be gathered and tightly attached between the lower baffle 7 and the upper baffle 8 through the yarn restraining device. The gathering point of the lower baffle 7 should be more forward than that of the upper baffle 8 so that the multi-strand yarn 9 is inclined so that the knotting head can be completely hooked to the binding strand 9, and the knotting head is positioned at the right side of the binding strand 9, as shown in fig. 1 and 2.

The knotting head then starts a rotation of one turn counter-clockwise, the "L" shaped knotting head being able to hook onto the inclined binding strand 9 and loop, as shown in figure 3. The knotting head continues to rotate after looping, but moves axially backwards at the same time, so that the knotting head can be positioned behind the gathering point of the binding strand to the upper baffle plate 8 when rotating for the second circle. At this moment, the wire hook 2 and the wire pulling rocker 5 also start to move, the wire hook 2 moves forwards along the axial direction, the wire hook is exposed out of the knotting head to be hooked with a wire, the wire pulling rocker 5 rotates in a fixed axis mode, and the movement of the wire pulling rocker 5 has two purposes: firstly, the binding strand 9-2 at the tail end is poked into the wire hook 2, and secondly, the binding strand 9 is sent to the scissor opening of the scissor 6 to be cut off. When the binding strand 9 is pulled into the wire hook 2, the knotting head also moves to the rearmost end, and because the drag ring push rod 3 is kept static in the axial direction, the axial movement of the knotting head causes the drag ring push rod 3 to push the previously formed ring out of the knotting head shaft neck to form knocking-over, as shown in fig. 4.

And finally, closing the edge of the scissors 6 to cut off the tail end binding stranded wire 9-2. At this time, as shown in fig. 5, when the second circle is rotated to half, on one hand, the knotting head 1 makes a forward axial movement, and the wire hook 2 hooks the tail end binding wire 9-2 to make a backward axial movement, so that the tail end of the binding wire 9 forms a knot through the circle which is separated from the shaft neck; on the other hand, the hook mouth of the knotting head 1 rotates to be close to the knotting rocker 4, the knotting rocker 4 rotates around a fixed shaft, the front binding wire 9-1 is dragged to move backwards, and formed knots are separated from the knotting head 1 under the action of the lower baffle 7 and the knotting head 1 moving outwards. The binding strand at the tail end retained in the wire hook 2 is also pulled out along the same trend, and meanwhile, the formed knot is tightened, so that the knotting reliability of the device is ensured. At this point, the knotting motion is finished, the knotting head 1 continues to rotate for the latter half circle, and all the parts return to the initial positions to prepare for the next knotting.

The cut tail yarn can be collected to a waste yarn box by a negative pressure generator, all actions on the device can be driven by the same power, and the knotting device is convenient to install and disassemble and is beneficial to later maintenance of the knotting device.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the scope of the present invention in any way, and all technical solutions obtained by using equivalent substitution methods fall within the scope of the present invention.
