Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of textile machinery, and particularly relates to a short fiber and long line composite false twisting device. BACKGROUND

[0002] In the prior art, a yarn false twisting device is disclosed in a Chinese patent document with the patent publication number CN222182617U, which comprises a first false twisting assembly for twisting yarns and a second false twisting assembly for reinforcing yarns, wherein the first false twisting assembly comprises a hollow motor and a first false twister, the hollow motor is fixedly connected with the first false twister and drives the first false twister to rotate.

[0003] The first false twister comprises a first connecting seat and a first false twisting arm, the first false twisting arm is located below the first connecting seat and is fixedly connected with the first connecting seat, the first connecting seat is a hollow structure, and the rotating shaft of the hollow motor is fixedly connected with the first connecting seat.

[0004] The first false twisting arm comprises a first supporting rod, a first limiting rod and a first connecting rod, the two ends of the first supporting rod are fixedly connected with the middle part of the first limiting rod and one end of the first connecting rod respectively, the first supporting rod and the first limiting rod are in an inverted T shape, and the connection part of the first supporting rod and the first limiting rod is smoothly transitioned through an arc surface.

[0005] During false twisting, the yarns pass through the hollow motor from the top end of the rotating shaft of the hollow motor and come out from the first connecting seat fixedly connected with the bottom end of the rotating shaft, the two yarns are separated by the first supporting rod, pass around the two sides of the first supporting rod, and are supported by the two arc transition connection parts on the two sides of the connection part of the first supporting rod and the first limiting rod, and when the hollow motor rotates at high speed, the first false twister rotates to perform first false twisting on the two yarns.

[0006] The yarns after the first false twisting need to come out from the position of the center directly below the first limiting rod and enter the second false twisting assembly, and if the yarns come out from the center of the first false twisting arm, the yarns will be tight and loose alternately, which causes the false twisting effect of the first false twisting arm to be invalid. In order to avoid the problem of invalid false twisting, the center axes of the second false twisting assembly and the first false twister coincide to guarantee the false twisting effect of the first false twisting arm, but such a design is very limited. CONTENT OF THE UTILITY MODEL

[0007] In view of the deficiencies in the prior art, the purpose of the present application is to provide a short fiber and long line composite false twisting device, which limits the yarns to come out from below the center of the false twister, improves the adaptability of the false twisting device and guarantees the false twisting effect.

[0008] The above purpose of the present application is realized through the following technical scheme:

[0009] A short fiber and long line composite false twisting device, comprising a false twister body, the false twister body comprising a connecting seat, a connecting piece and a limiting rod, the connecting piece being fixedly arranged between the connecting seat and the limiting rod, the bottom of the limiting rod being fixedly installed with a centering piece, the centering piece being provided with a threading ring with a center axis coinciding with the center axis of the false twister body, and a first vertical gap being left between the threading ring and the bottom of the limiting rod.

[0010] By adopting the above technical scheme, the two yarns pass through the threading ring, and since the threading ring is arranged directly below the bottom of the limiting rod and a first vertical gap is left between the threading ring and the limiting rod, it is ensured that the yarns can always be inside the threading ring during false twisting, the situation of yarn deviation is reduced, and the problem of poor false twisting effect caused by yarn deviation is avoided. At the same time, the vertical gap between the threading ring and the bottom of the limiting rod is designed, so that the yarns can maintain appropriate tension during false twisting, and the false twisting quality and stability are improved.

[0011] The application further provides that the shapes of the limiting rod and the centering piece are both U-shaped.

[0012] By adopting the above technical scheme, the limiting rod and the centering piece are both designed in a U shape, which can better ensure the stability of the yarns during false twisting. Specifically, the U-shaped design can reduce the friction force generated by the contact between the yarns and the limiting rod and the centering piece during movement, reduce the risk of yarn breakage, and improve production efficiency and product quality.

[0013] The application further provides that the two ends of the centering piece are welded and fixed on the two ends of the U-shaped limiting rod.

[0014] By adopting the above technical scheme, the two ends of the centering piece are welded and fixed on the two ends of the U-shaped limiting rod, so that the connection between the centering piece and the limiting rod is more stable and reliable, the position accuracy of the threading ring is ensured, and the yarn deviation during false twisting is effectively avoided, thereby ensuring the stability and consistency of the false twisting effect.

[0015] The application further provides that a plurality of locking holes are arranged on the two ends of the limiting rod in the direction of the false twister body, the centering piece is provided with a fastener, and the fastener is detachably matched with one of the locking holes after passing through the centering piece.

[0016] By adopting the above technical scheme, with the cooperation of the plurality of locking holes and the fastener, the vertical height difference between the limiting rod and the fastener is first adjusted, so that the vertical gap therebetween can be adjusted, and after the vertical gap is adjusted, the locking piece is locked and fixed, so that the threading height of the yarns at the bottom of the centering piece can be controlled, and the threading height can be actually adjusted to be higher or lower, thereby meeting different production requirements.

[0017] The application is further provided that the connecting piece comprises a Y-shaped false twist arm, one end of the Y-shaped false twist arm is fixedly connected with the bottom of the connecting seat, and the other end is fixedly connected with the middle part of the limiting rod.

[0018] By adopting the above technical scheme, the design of the Y-shaped false twist arm enables the yarn to realize false twisting, and the two yarns can be more stably distributed on both sides of the Y-shaped false twist arm during the false twisting process, avoiding the problem of yarn deviation during the false twisting process, thereby improving the false twisting effect. At the same time, the structure of the Y-shaped false twist arm can also effectively reduce the friction between the yarns, reduce the risk of yarn damage, and further improve the product quality.

[0019] The application is further provided that the centering piece comprises two L-shaped centering arms, the threading ring comprises an upper threading ring and a lower threading ring with coinciding central axes, the upper threading ring is located at the end of one of the centering arms, the lower threading ring is located at the end of the other centering arm, and a second vertical gap is left between the upper threading ring and the lower threading ring.

[0020] By adopting the above technical scheme, the two L-shaped centering arms can effectively ensure that the yarn enters from above the central axis and aligns with the center position, avoiding the problem of yarn deviation on the limiting rod. The second vertical gap between the upper threading ring and the lower threading ring further ensures the stability and uniformity of the yarn during the false twisting process, thereby improving the false twisting effect and preventing the phenomenon of one tight and one loose caused by yarn deviation.

[0021] In summary, the beneficial technical effects of the application are:

[0022] 1. By designing the centering piece and the threading ring, the yarn can always remain in the center state when passing through the false twister, avoiding the phenomenon of one tight and one loose caused by yarn deviation, and improving the stability and reliability of the false twisting effect;

[0023] 2. The vertical gap design between the threading ring and the bottom of the limiting rod ensures smooth transition of the yarn before entering the second false twisting assembly, reduces the risk of yarn breakage, and improves the safety of the overall false twisting process;

[0024] 3. The U-shaped structure of the centering piece and the limiting rod simplifies the overall design of the device, reduces the manufacturing and maintenance costs, and at the same time enhances the stability of the structure. BRIEF DESCRIPTION OF DRAWINGS
