Description

Technical Field

[0001] This utility model relates to the field of textile accessories technology, and in particular to a twist reducer that can adjust yarn twist. Background Technology

[0002] In textile processing, the untwisting device is a crucial auxiliary equipment, primarily used to eliminate the internal stress generated during the twisting process of yarn or fiber, ensuring the stability and uniformity of the yarn structure. Its core function is to counteract the original twist of the yarn by applying reverse force or movement, thereby improving the yarn's physical properties and performance. Untwisted yarn is softer and fluffier, reducing breakage and defect rates in subsequent weaving or knitting processes, while also improving the fabric's hand feel and appearance quality. Furthermore, the untwisting device can adjust the yarn's tension balance, preventing fabric deformation or color differences caused by uneven twist. In the processing of specialty yarns (such as high-elasticity yarn and core-spun yarn), the role of the untwisting device is particularly prominent, precisely controlling the final shape of the yarn to meet the needs of functional textiles. Through this process, the yarn's processability and finished product quality are significantly optimized, laying a solid foundation for subsequent dyeing and finishing processes.

[0003] A search revealed that patent specification CN208776903U discloses an adjustable yarn twist reducer, comprising a twist reducer body fitted onto a yarn bobbin rod. The twist reducer body includes a sleeve rod, a large disc, and a small disc. The large and small discs each have a central hole and a threading hole. The sleeve rod passes sequentially through the central holes of the large and small discs, which are spaced apart on the sleeve rod. The sleeve rod is a hollow rubber rod fitted onto the yarn bobbin rod, and the diameter of the central holes of the large and small discs matches that of the sleeve rod. This adjustable yarn twist reducer can adjust the twist and prevent yarn curling.

[0004] The aforementioned twist reducer has several shortcomings in use. First, the angle between the threading holes in the large and small discs cannot be quickly adjusted as needed, and their positions do not change arbitrarily after adjustment. Second, the large and small discs are not easy to disassemble and replace. Therefore, the inventors aim to optimize and improve it. Summary of the Invention

[0005] The purpose of this invention is to overcome the aforementioned problems in traditional technology and provide a twist reducer with adjustable yarn twist.

[0006] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution: An adjustable yarn twist reducer includes a first support column, a second support column, a first fastening screw, a small disc, a snap-fit ​​post, a compression spring, a large disc, a second fastening screw, and a mounting clip. One end of the first support column has a first internal thread groove. The small disc is mounted on the first support column by the first fastening screw screw, which is screwed into the first internal thread groove. The other end of the first support column has a snap-fit ​​groove, the inner end of which has a second internal thread groove. One end of the second support column has a snap-fit ​​post that snaps into the snap-fit ​​groove. Both the second support column and the snap-fit ​​post have a clearance through hole that mates with the second fastening screw. The large disc and the mounting clip are respectively mounted on the outer sides of the second support column and the snap-fit ​​post by the second fastening screw screw screwed into the second internal thread groove. A compression spring is sleeved on the outer side of the snap-fit ​​post, with both ends of the compression spring abutting against the second support column and the large disc, respectively.

[0007] Furthermore, in the aforementioned adjustable yarn twist reducer, the small disc has a first central hole at its center. The diameter of the first central hole matches the outer diameter of the rod body in the first fastening screw, and the outer diameter of the first central hole is smaller than the outer diameter of the end of the first fastening screw.

[0008] Furthermore, in the aforementioned adjustable yarn twist reducer, the large disc has a second central hole at its center, and the diameter of the second central hole matches the outer diameter of the snap-fit ​​post.

[0009] Furthermore, in the aforementioned adjustable yarn twist reducer, the outer diameters of the first support column and the second support column are equal, the outer diameter of the second support column is greater than the outer diameter of the compression spring, and the outer diameter of the compression spring is greater than the outer diameter of the snap-fit ​​column.

[0010] Furthermore, in the aforementioned adjustable yarn twist reducer, the large disc and the small disc are made of metal or plastic materials.

[0011] Furthermore, in the aforementioned adjustable yarn twist reducer, the second support column and the large disc are provided with a rough layer to increase frictional resistance at the contact position near the compression spring.

[0012] Furthermore, in the aforementioned adjustable yarn twist reducer, the small disc has a first perforation at an eccentric position, and a first shock-absorbing rubber ring is installed in the first perforation; the large disc has a second perforation at an eccentric position, and a second shock-absorbing rubber ring is installed in the second perforation.

[0013] Furthermore, in the aforementioned adjustable yarn twist reducer, the distance between the axes of the first perforation and the second perforation and the axis of the first support column is equal.

[0014] The beneficial effects of this utility model are: 1. The angle of the threading hole can be quickly adjusted and the position is stable: The angle between the threading holes on the large and small discs can be quickly adjusted as needed, and the positions of the two will not change arbitrarily after adjustment, which improves the flexibility and stability of the untwisting operation.

[0015] 2. Easy to disassemble and replace: The large and small discs are easy to disassemble and replace, and the parts can be adjusted according to different yarn types or processing requirements, which improves the versatility and applicability of the equipment.

[0016] 3. Stable structure: The structure of the anti-twist device is stable, with the connection between the various parts of the device being securely connected through the snap-fit ​​posts, snap-fit ​​grooves and fastening screws. This ensures the stability of the structure during operation and reduces the impact of equipment shaking on the yarn anti-twist effect.

[0017] 4. Shock absorption function: Shock-absorbing rubber rings are installed in the perforations of the small and large discs, which can reduce problems such as yarn breakage caused by vibration during the untwisting process and improve the yarn processing quality.

[0018] 5. Increase frictional resistance: A rough layer is set at the contact point between the second support column and the large disc near the compression spring, which increases frictional resistance and helps to better fix the position of the large disc and prevent it from rotating at will.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-5 As shown, this embodiment provides an adjustable yarn twist reducer, including a first support column 1, a second support column 2, a first fastening screw 3, a small disc 4, a snap-fit ​​post 5, a compression spring 6, a large disc 7, a second fastening screw 8, and a mounting clip 9. One end of the first support column 1 has a first internal thread groove, and the small disc 4 is mounted on the first support column 1 by the first fastening screw 3 screwed into the first internal thread groove. The other end of the first support column 1 has a snap-fit ​​groove, and the inner end of the snap-fit ​​groove has a second internal thread groove. One end of the second support column 2 has a snap-fit ​​post 5 that snaps into the snap-fit ​​groove, and both the second support column 2 and the snap-fit ​​post 5 have a clearance through hole that mates with the second fastening screw 8. The large disc 7 and the mounting clip 9 are respectively mounted on the outer sides of the second support column 2 and the snap-fit ​​post 5 by the second fastening screw 8 screwed into the second internal thread groove. A compression spring 6 is sleeved on the outer side of the snap-fit ​​post 5, and the two ends of the compression spring 6 abut against the second support column 2 and the large disc 7, respectively.

[0024] In this embodiment, the small disc 4 has a first central hole at its center. The diameter of the first central hole matches the outer diameter of the rod body in the first fastening screw 3. The outer diameter of the first central hole is smaller than the outer diameter of the end of the first fastening screw 3.

[0025] In this embodiment, the large disc 7 has a second central hole at its center, and the diameter of the second central hole matches the outer diameter of the snap-fit ​​post 5.

[0026] In this embodiment, the outer diameters of the first support column 1 and the second support column 2 are equal, the outer diameter of the second support column 2 is greater than the outer diameter of the compression spring 6, and the outer diameter of the compression spring 6 is greater than the outer diameter of the snap-fit ​​column 5.

[0027] In this embodiment, the large disk 7 and the small disk 4 are made of metal or plastic materials.

[0028] In this embodiment, the second support column 2 and the large disc 7 are provided with a rough layer to increase frictional resistance at the contact position near the compression spring 6.

[0029] In this embodiment, the small disc 4 has a first through hole at an eccentric position, and a first shock-absorbing rubber ring 10 is installed in the first through hole; the large disc 7 has a second through hole at an eccentric position, and a second shock-absorbing rubber ring 11 is installed in the second through hole.

[0030] In this embodiment, the distance between the axes of the first perforation and the second perforation and the axis of the first support column is equal.

[0031] The specific application of this embodiment is as follows: Installation process: The small disc 4 is screwed into the first internal thread groove at one end of the first support column 1 through the first fastening screw 3, thereby installing the small disc 4 on the first support column 1. At this time, the rod of the first fastening screw 3 passes through the first central hole of the small disc 4. Since the outer diameter of the first central hole is smaller than the outer diameter of the middle end of the first fastening screw 3, the small disc 4 is fixed between the end of the first fastening screw 3 and the first support column 1.

[0032] The snap-fit ​​pin 5 of the second support column 2 is snapped into the snap-fit ​​groove at the other end of the first support column 1. At the same time, the second fastening screw 8 passes through the clearance through hole opened by the second support column 2 and the snap-fit ​​pin 5, and is screwed into the second internal thread groove at the inner end of the snap-fit ​​groove, so as to realize the connection and fixation between the second support column 2 and the first support column 1.

[0033] The compression spring 6 is placed on the outside of the snap-fit ​​post 5, and then the large disc 7 is placed on the snap-fit ​​post 5 through its second central hole, so that the two ends of the compression spring 6 abut against the second support post 2 and the large disc 7 respectively. Finally, the mounting clip 9 is installed on the outside of the snap-fit ​​post 5 through the second fastening screw 8 to further fix the large disc 7.

[0034] Adjustment process: When it is necessary to adjust the angle between the threading holes (first and second holes) on the large disc 7 and the small disc 4, the large disc 7 and the second support column 2 are relatively fixed in position when not subjected to a large external force, due to the action of the compression spring 6 and the rough layer. When a certain external force is applied to overcome the elastic force of the compression spring 6 and the frictional force generated by the rough layer, the large disc 7 can be rotated, changing the relative angle between the second hole on it and the first hole on the small disc 4, thereby adjusting the angle between the threading holes. After adjusting to a suitable angle, the external force is stopped, and the position of the large disc 7 remains fixed under the action of the elastic force of the compression spring 6 and the frictional force of the rough layer, and will not move arbitrarily.

[0035] Twist reduction process: The yarn passes sequentially through the first perforation of the small disc 4 (where the first shock-absorbing rubber ring 10 reduces yarn vibration) and the second perforation of the large disc 7 (where the second shock-absorbing rubber ring 11 reduces yarn vibration). During the yarn movement, the relative positional relationship of the threading holes on the large disc 7 and the small disc 4, as well as the interaction between the yarn and the shock-absorbing rubber rings inside the perforations, applies a reverse force or movement to the yarn, counteracting the original twist of the yarn and achieving the twist reduction function. This makes the yarn softer and fluffier, reducing the breakage rate and defect rate in subsequent weaving or knitting processes, and improving the hand feel and appearance quality of the fabric.

[0036] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to specific implementation methods. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
