Description

Technical Field

[0001] The utility model relates to the field of tension regulation, in particular to a cotton yarn tension regulating device. Background Art

[0002] Cotton yarn is a textile fabric formed by weaving cotton yarns. When multiple cotton yarns are moving, the tension needs to be regulated to avoid the breakage of the cotton yarns due to excessive tension, and also to avoid the cotton yarns being too loose due to too low tension, which would cause "horizontal stripes" to appear on the cotton yarn weaving process.

[0003] In the prior art, tension is generally controlled automatically through tension sensors. However, in the fabric weaving process, there are a large number of warp and weft threads, and each thread has a different unwinding roller for unwinding, making synchronous control impossible. If multiple tension sensors are used for distributed control, the cost is relatively high. Utility Model Content

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-2 In an embodiment of the utility model, a cotton yarn tension control device comprises a handle 1 and a fixed block 5, wherein the handle 1 is rotatably connected to a support surface, and the fixed block 5 is fixedly connected to the support surface;

[0019] The top of the outer periphery of the handle 1 is fixedly connected with a lower connecting buckle 2, the bottom end surface of the fixed block 5 is connected with an upper connecting buckle 4, and the two ends of the tension spring 3 are respectively hooked with the lower connecting buckle 2 and the upper connecting buckle 4;

[0020] A rod portion 6 is integrally formed at one end of the handle 1 , and a downwardly extending rotating ear 7 is integrally formed at the end of the rod portion 6 . A rotating wheel 8 for guiding the cotton yarn 9 is rotatably connected to the inner side of the rotating ear 7 .

[0021] In this embodiment: one end of the cotton yarn 9 is connected to the unwinding roller, and the other end of the cotton yarn 9 is woven into a cotton yarn cloth through warp and weft. The cotton yarn cloth is wound up by the winding roller after being woven and formed. The cotton yarn is always in contact with the rotating wheel 8 during the process. When the tension is too large, the cotton yarn pulls the rotating wheel 8, the rotating wheel 8 pulls the rotating ear 7, the rotating ear 7 pulls the rod 6, and the rod 6 pulls the handle 1, thereby realizing the downward rotation of the device to avoid the breakage of the cotton yarn caused by excessive tension;

[0022] During the above process, the tension spring 3 is stretched, and when the tension changes from large to small, the tension spring 3 is reset, pulling the handle 1 to rotate upward, giving the cotton yarn 9 enough tension to prevent the cotton yarn from forming "horizontal stripes" on the cotton yarn fabric due to excessive relaxation.

[0023] Please refer to Figure 1 and Figure 2 A rotating part 10 is integrally formed at one end of the handle 1 away from the rod 6. An axial hole is opened on the rotating part 10. An axial body is fixedly connected to the inner wall of the axial hole. The axial body is rotatably connected to the supporting surface through a bearing.

[0024] In this embodiment: when the handle 1 is subjected to force, the handle 1 drives the rotating part 10 to move synchronously, and the rotating part 10 drives the shaft body to rotate synchronously, and the shaft body and the supporting surface rotate relative to each other, thereby realizing the up and down rotation of the device.

[0025] Please refer to Figure 1 and Figure 2 A rotating hole is opened on the rotating ear 7, and the inner wall of the rotating hole is rotatably connected with a rotating shaft through a bearing, and the rotating shaft is integrally formed with the end surface of the rotating wheel 8.

[0026] In this embodiment: during the movement of the cotton yarn 9, the cotton yarn 9 contacts the rotating wheel 8, and the rotating wheel 8 rotates under the action of friction. The rotating wheel 8 drives the rotating shaft to rotate in the rotating hole, and the bearing can effectively reduce the friction during the rotation process.

[0027] Please refer to Figure 1 and Figure 2 The outer periphery of the rotating wheel 8 is formed with an inwardly recessed annular groove, which contacts the outer wall of the cotton yarn 9.

[0028] In this embodiment, the annular groove can limit the position of the cotton yarn 9 to a certain extent, so as to prevent the cotton yarn 9 from contacting the rotating ear 7 or separating from the rotating wheel 8 during movement, thereby preventing the cotton yarn 9 from breaking due to excessive friction.

[0029] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
