Abstract
Description
[Technical Field]
[0001] This utility model relates to a spindle, specifically a re-twisting spindle for a primary and secondary twisting integrated machine, and belongs to the field of textile machinery technology. [Background Technology]
[0002] The spindle is an important component of yarn production equipment such as twisting machines and winding machines. It twists the yarn by rotating and drives the yarn bobbin to rotate, thereby winding the twisted yarn into shape.
[0003] The existing spindles, as shown in the applicant's earlier utility model patent No. 202020424236.9, twist the yarn by driving the twisting spindle to rotate through a twisting motor. However, since the twisting spindle is installed vertically and only has support at the bottom, it can only be used to produce finer yarns and cannot be used to produce coarser yarns, which has certain limitations.
[0004] The yarn guiding mechanism is a crucial component within the spindle, guiding the yarn radially along the yarn bobbin and winding it onto the bobbin. Existing yarn guiding mechanisms, such as those described in the applicant's earlier utility model patent No. 201420209017.3, utilize a motor rotating in both directions to drive a steel wire wheel, which in turn drives a steel wire rope. This rope, in turn, causes the yarn guide head to reciprocate, thus guiding the yarn. However, the reciprocating movement of the yarn guide head in these mechanisms creates uneven tension on the yarn. For example, the yarn tension differs depending on whether the guide head is in the middle of the bobbin or at either end, resulting in inconsistent tension as the yarn winds onto the bobbin and negatively impacting the quality of the wound yarn.
[0005] Therefore, in order to solve the above-mentioned technical problems, it is indeed necessary to provide an innovative retwisting spindle for a primary and secondary retwisting integrated machine to overcome the defects in the prior art. [Utility Model Content]

Detailed Implementation Methods
[0028] Please refer to the instruction manual appendix. Figure 1 To be continued Figure 10 As shown, this utility model is a retwisting spindle of a primary and secondary twisting integrated machine, which is installed on the frame 10. It consists of several parts, including a left main shaft 11, a right main shaft 12, a turntable 2, a flying wing 3, a left mounting plate 41, a right mounting plate 42, a retwisting overfeed 5, a yarn guiding device 6, a friction roller 7, and a bobbin frame 8.
[0029] The left spindle 11 and the right spindle 12 are horizontally and coaxially arranged and mounted on the frame 10, so that the two ends of the retwisting spindle are supported on the frame 10 and installed horizontally. Since the two ends of the retwisting spindle are supported by the left spindle 11 and the right spindle 12 respectively, it has a large load-bearing capacity and runs smoothly, making it particularly suitable for the production of coarser yarns.
[0030] The left main shaft 11 is hollow and connected to an external power source for inputting external power. The turntable 2 is connected to the left main shaft 11 and rotates with the left main shaft 11. The edge of the turntable 2 has a yarn passage hole 21. A yarn 13 passes through the yarn passage hole 21 into the turntable 2 and then into the center of the left main shaft 11. The retwisting overfeed 5 is pivotally connected to the left main shaft 11, and the yarn 13 is wound onto the retwisting overfeed 5 after passing through the left main shaft 11.
[0031] The flying wing 3 is connected to the right main shaft 12 and rotates with the right main shaft 12. Specifically, an intermediate shaft 14 is pivotally connected between the left mounting plate 41 and the right mounting plate 42. Drive pulleys I141 are mounted at both ends of the intermediate shaft 14. Drive pulleys II142 are mounted on the left main shaft 11 and the right main shaft 12, respectively. Drive pulleys I141 and II142 are connected by a synchronous belt I143, enabling the left main shaft 11 to drive the right main shaft 12. The right main shaft 12 then drives the flying wing 3, causing the yarn 13 to rotate with the turntable 2 and the flying wing 3, thus forming a yarn loop.
[0032] Furthermore, an intermediate pulley 144 is provided on the intermediate shaft 14, and the intermediate pulley 144 drives a generator 9 through a belt 145 to generate electricity. The generator 9 is electrically connected to and supplies power to electrical components such as the retwisting overfeed 5, the yarn guiding device 6, and the friction roller 7, thereby eliminating the need to use wires to transmit external power to the yarn loop, making the twisting performance stable and reliable, and greatly reducing the failure rate.
[0033] The left mounting plate 41 is mounted on the left spindle 11 via bearings; the right mounting plate 42 is mounted on the right spindle 12 via bearings. A horizontal mounting seat 44 is provided between the left mounting plate 41 and the right mounting plate 42. The left mounting plate 41, the right mounting plate 42, and the horizontal mounting seat 44 remain stationary due to their own weight, while the left spindle 11 and the right spindle 12 can rotate.
[0034] A retaining ring 46 is installed around the edge of the left mounting plate 41. The yarn 13 abuts against the retaining ring 46, preventing the yarn 13 from touching the components inside the retaining ring 46 when it rotates, and ensuring that the yarn air loop expands. An overfeed motor 51 is further installed on the left mounting plate 41. The overfeed motor 51 is connected to and drives the retwisting overfeed 5 via a synchronous belt II 52, causing the retwisting overfeed 5 to rotate and feed the yarn.
[0035] The yarn guiding device 6, friction roller 7, bobbin holder 8, and generator 9 are respectively mounted on the horizontal mounting base 44, while the intermediate shaft 14 is located below the horizontal mounting base 44 to prevent broken yarn from winding onto the intermediate shaft 14. The yarn fed in by the retwisting overfeed 5 moves back and forth left and right under the guidance of the yarn guiding device 6. The bobbin holder 8 is equipped with a yarn bobbin 81, which abuts against the friction roller 7. The rotation of the friction roller 7 drives the rotation of the yarn bobbin 81, thereby winding the yarn 13 onto the yarn bobbin 81. The friction roller 7 and bobbin holder 8 are existing technologies, so they will not be described in detail here.
[0036] The yarn guiding device 6 is assembled from several parts, including a yarn guiding base plate 62, a yarn guiding wheel 631, a yarn guiding motor 632, a synchronous belt III 633, a yarn guiding head 64, a guide rail 65, a slider 66, a coil spring 67, and a steel wire rope 68.
[0037] The yarn guide base plate 62 is fixed to the left mounting plate 41 and the right mounting plate 42, and is horizontally arranged. The yarn guide wheels 631 are pivotally connected to the yarn guide base plate 62, and there are two of them, located on the left and right sides of the yarn guide base plate 62.
[0038] The yarn guiding motor 632 is mounted on the yarn guiding base plate 62, and is connected to and drives one of the yarn guiding wheels 631. The synchronous belt III 633 is sleeved on the two yarn guiding wheels 631 and is driven by the yarn guiding wheels 631, thereby realizing the movement of the synchronous belt III 633.
[0039] The yarn guide head 64 is fixed to the synchronous belt III 633 and is driven by the synchronous belt III 633 to move back and forth. The yarn guide head 64 drives the yarn 13 to move left and right, so that the yarn is distributed radially on the yarn bobbin 81. Specifically, the yarn guide motor 632 rotates in the forward or reverse direction and drives the yarn guide wheel 631. The yarn guide wheel 631 drives the synchronous belt III 633, which in turn drives the yarn guide head 64, causing the yarn guide head 64 to move back and forth, thereby guiding the yarn 13.
[0040] A yarn guide seat 621 is installed on the yarn guide base plate 62, and a guide groove 622 is provided on one side of the yarn guide seat 621. A guide block 641 is provided on one side of the yarn guide head 64. The guide block 641 cooperates with the guide groove 622 to limit the yarn guide head 64, so that the yarn guide head 64 can only move back and forth along the extension direction of the guide groove 622, and prevent the yarn guide head 64 from deflecting. A shielding cover 623 is provided on the top of the yarn guide seat 621. The shielding cover 623 shields the synchronous belt III 633, protects the synchronous belt III 633, and prevents lint from accumulating on the synchronous belt III 633.
[0041] The guide rail 65 is installed on one side of the yarn guide base plate 62. The slider 66 cooperates with the guide rail 65. One end of the steel wire rope 68 is connected to the coil spring 67, and the other end is connected to the slider 66. The slider 66 is provided with a thread guide wheel 61; the yarn 13 is wound onto the thread guide wheel 61. The yarn 13 and the steel wire rope 68 are located on different sides of the thread guide wheel 61, so that the steel wire rope 68 or the yarn 13 can pull the slider 66 respectively, so that the slider 66 can move along the guide rail 65.
[0042] The coil spring 67 is mounted on the right mounting plate 42, and it pulls the slider 66 by winding the steel wire rope 68.
[0043] Furthermore, a cover 69 is installed on one side of the yarn guide plate 62, and a limiting groove 691 is provided on the cover 69; the slider 66 is located in the limiting groove 691 to limit the movement range of the slider 66. The cover 69 and the right mounting plate 42 are respectively provided with thread guide nozzles 692 on the side near the coil spring 67; the wire rope 68 passes through the thread guide nozzles 692 to achieve deflection, and is located below the cover 69 to protect the moving wire rope 68.
[0044] As attached Figure 8As shown, when the yarn guide head 64 moves to the left, that is, away from the coil spring 67, the yarn guide head 64 drives the yarn 13 to move to the left. If the slider 66 is fixed, the tension of the yarn 13 reaches its maximum when the yarn guide head 64 reaches the far left. This design uses the yarn 13 to drive the slider 66 to move to the left along the guide rail 65. The slider 66 pulls the wire rope 68 to release the coil spring 67, and the elasticity of the coil spring 67 counteracts part of the tension on the yarn 13, thus reducing the tension on the yarn. (See attached diagram) Figure 9 As shown, conversely, when the yarn guide head 64 moves to the right, that is, when it approaches the coil spring 67, the elastic restoring force of the coil spring 67 pulls the slider 66, causing the slider 66 to move to the right along the guide rail 65.
[0045] The working process of the retwisting spindle in this utility model's integrated primary and secondary twisting machine is as follows: The external power drives the left main shaft 11, which in turn drives the turntable 2 via the intermediate shaft 14, and the right main shaft 12 in turn drives the wing 3. The yarn 13 passes through one end of the wing 3 and enters through the yarn passage hole 21 of the turntable 2. Twisting is achieved by forming a yarn air ring through the rotation of the turntable 2 and the wing 3. The yarn 13 then enters the center of the left main shaft 11 and exits from the shaft end, entering the retwisting overfeed 5 within the yarn air ring. The yarn fed by the retwisting overfeed 5 is guided by the yarn guide device 6 and moves back and forth. The rotation of the friction roller 7 then drives the yarn bobbin 81 to rotate, thereby winding the yarn 13 onto the yarn bobbin 81.
[0046] The above-described specific embodiments are merely preferred embodiments of this invention and are not intended to limit this invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
