Description

Technical Field

[0001] The present application relates to the technical field of textile machinery, and in particular to a yarn tension linear variation control mechanism and a winding machine. Background Art

[0002] During the winding process, the magnitude and uniformity of the tension directly affect the uniformity of the yarn, which in turn affects the subsequent processes and the quality of the fabric. Therefore, the tension adjustment capability of the winder is one of the important parameters for measuring the performance of the winder. Depending on the tension loading method, the tension mechanism of the winder is mainly divided into a disc tension mechanism and a gate tension mechanism. Among them, the gate tension mechanism mainly adjusts the yarn tension by adjusting the comb tension and spring force of the gate teeth to change the angle of the yarn around the comb teeth. It is mainly used for long filaments such as polyester. At present, most gate tension mechanisms adjust the angle of the gate teeth by changing the weight and number of weights to obtain the required yarn tension. However, the yarn tension adjusted by this scheme has poor stability and a small adjustment range, and cannot achieve stepless adjustment to obtain a yarn package with consistent density inside and outside.

[0031] Figure 1 and Figure 2 Schematic diagram of the structure of the yarn tension linear change control mechanism 100 provided in the embodiment of the present application at different angles, such as Figure 1 and Figure 2 As shown, an embodiment of the present application provides a yarn tension linear change control mechanism 100, including a yarn clamping component 10 and a tension adjustment component 20.

[0032] The yarn clamping assembly 10 is used for clamping yarn, and includes a bracket 11 , a fixed clamping member 12 , a movable clamping member 13 , a weighting member 14 , and a first connecting rope 15 .

[0033] The fixed clamping member 12 is fixedly mounted on the bracket 11, and the movable clamping member 13 is rotatably mounted on the bracket 11. A gap is provided between the fixed clamping member and the movable clamping member 13 for the yarn to pass through, and the yarn can pass through this gap from bottom to top. When the movable clamping member 13 rotates closer to the fixed clamping member 12 to a certain extent, the gap between the two decreases, thereby clamping the yarn. When the movable clamping member 13 rotates away from the fixed clamping member 12 to a certain extent, the gap between the two increases, and the yarn is released.

[0034] As an example, both the fixed clamping member 12 and the movable clamping member 13 are ceramic gates, and the two gates are staggered. When the two gates are staggered and engaged, the yarn can be clamped, and when the two gates are separated, the yarn can be released. As another example, both the fixed clamping member 12 and the movable clamping member 13 are clips. The gates and clips can be respectively suitable for different types of yarns, and those skilled in the art can select them according to their needs.

[0035] A weight member 14 is disposed on the side of the fixed clamping member 12 facing away from the movable clamping member 13 and is connected to the movable clamping member 13 via a first connecting rope 15. The weight member 14 is used to provide the clamping force required by the movable clamping member 13 to clamp the yarn. The first connecting rope 15 can be made of nylon, polyester fiber, or other flexible material. As an example, the weight member 14 is a weight and the first connecting rope 15 is a nylon rope.

[0036] The tension adjusting assembly 20 is used to adjust the clamping force of the yarn clamping assembly 10 on the yarn, so that the tension of the yarn changes linearly. Specifically, the tension adjusting assembly 20 is used to adjust the clamping force of the movable clamping member 13 on the yarn.

[0037] The tension adjustment assembly 20 includes a swing arm 21, a rotating shaft 22, a support member 23, a pulley 24, and a second connecting rope 25. The middle portion of the swing arm 21 is mounted on the horizontally arranged rotating shaft 22, and the swing arm 21 is rotatable in a vertical plane around the rotating shaft 22. One end of the swing arm 21 is close to the yarn clamping assembly 10 and a support member 23 is mounted thereon, and the support member 23 provides support for the first connecting rope 15. The other end of the swing arm 21 is away from the yarn clamping assembly 10 and a pulley 24 is mounted thereon. One end of the second connecting rope 25 is connected to the pulley 24, and the other end of the second connecting rope 25 is used to connect to the cradle arm 400 connected to the end of the winding drum 200 (see Figure 3 ).

[0038] As an example, the swing arm 21 includes a long arm portion 211 and a short arm portion 212, and the long arm portion 211 and the short arm portion 212 are arranged at an obtuse angle. A support member 23 is installed on one end of the long arm portion 211, and a pulley 24 is installed on one end of the short arm portion 212. The other end of the long arm portion 211 and the other end of the short arm portion 212 are connected and the connection is installed on the rotating shaft 22; the support member 23 is a rod body; and the second connecting rope 25 is a steel wire rope.

[0039] The support member 23 may be provided with a through hole for the first connecting rope 15 to pass through. The through hole can prevent the first connecting rope 15 from falling off the support member 23 , thereby improving the stability of the support member 23 in supporting the first connecting rope 15 .

[0040] The embodiment of the present application further provides a winding machine, which mainly includes the above-mentioned yarn tension linear change control mechanism 100, a winding bobbin 200, a friction roller 300 and a cradle arm 400.

[0041] The winding bobbin 200 cooperates with the friction roller 300 , and the end of the winding bobbin 200 is connected to the cradle arm 400 , and the cradle arm 400 is connected to the other end of the second connecting rope 25 .

[0042] Figure 3 This is a front view of the winding machine provided in an embodiment of the present application when the winding bobbin 200 is in an empty bobbin state. Figure 4 The side view of the winding machine provided in the embodiment of the present application when the winding bobbin 200 is in an empty bobbin state, as shown in FIG. Figure 3 and Figure 4 As shown, when the winding bobbin 200 is in an empty bobbin state, the winding bobbin 200 naturally rests on the friction roller 300, the end where the pulley 24 of the swing arm 21 is located is at a low position, and the end where the support member 23 of the swing arm 21 is located is at a high position.

[0043] As the yarn winding proceeds, the diameter of the winding bobbin 200 increases linearly, and the winding bobbin 200 drives the cradle arm 400 to lift up, and the cradle arm 400 drives the second connecting rope 25 to pull up, and the second connecting rope 25 drives the swing arm 21 to rotate clockwise around the rotating shaft 22. The support member 23 lowers its position as the swing arm 21 rotates clockwise, so that the length of the force arm from the weight-applying member 14 to the movable clamping member 13 decreases linearly, and the lateral component of the weight-applying member 14 on the movable clamping member 13 decreases linearly, so that the clamping force of the movable clamping member 13 on the yarn, that is, the tension of the yarn, is linearly reduced.

[0044] final, Figure 5 This is a front view of the winding machine provided in an embodiment of the present application when the winding bobbin 200 is in a full bobbin state. Figure 6 The side view of the winding machine provided in the embodiment of the present application when the winding bobbin 200 is in a full bobbin state, as shown in FIG. Figure 5 and Figure 6As shown, the winding bobbin 200 is in a full bobbin state, wherein, compared with the position of the swing arm 21 when the winding bobbin 200 is in an empty bobbin state, the end where the pulley 24 of the swing arm 21 is located is in a high position, and the end where the support member 23 of the swing arm 21 is located is in a low position.

[0045] In summary, the embodiment of the present application provides a yarn tension linear change control mechanism, which includes a yarn clamping assembly and a tension adjustment assembly, wherein the first connecting rope connecting the weight-applying member of the yarn clamping assembly is supported by a support member of the tension adjustment assembly, and the support member is installed at one end of the swing arm, and the swing arm is rotatable around its middle part, and the other end of the swing arm is connected to a second connecting rope through a pulley, and the second connecting rope is connected to the cradle arm connected to the end of the winding drum. During operation, as the winding diameter of the yarn on the winding drum increases, the lateral component of the force of the weight-applying member on the movable clamping member decreases linearly, thereby achieving the effect of linearly reducing the clamping force of the movable clamping member on the yarn, that is, the tension of the yarn, so that a yarn package with consistent internal and external density can be obtained.

[0046] The above is only a specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the field can easily think of various changes or replacements within the technical scope disclosed in the present application, which should all be included in the scope of protection of the present application.
