Description

Technical Field

[0001] This application relates to the technical field of textile equipment, and in particular to a fabric tension regulating device. Background Technology

[0002] In the process of spinning yarn into fabric, the tension of the yarn needs to be adjusted so that the tension of the spun fabric meets the required standards.

[0003] However, the yarn tension varies during the weaving process for different yarn materials and fabrics of different standards. Therefore, when weaving fabrics, the yarn tension needs to be adjusted according to the requirements.

[0004] However, current yarn tension adjustment typically relies on friction. This involves placing a fixed plate beneath the yarn, then a vertical shaft on the fixed plate, a pressure plate fitted onto the shaft, and a spring on the pressure plate. By adjusting the pressure applied by the spring to the pressure plate, the combined pressure exerted on the yarn by the fixed plate is adjusted, thus regulating the friction force on the yarn. However, the fixed plate usually has two guide holes to guide the yarn, which needs to pass through. Since yarn is relatively soft, passing through these guide holes can be difficult.

[0005] Therefore, a new technical solution is needed to address the above problems. Utility Model Content

[0006] To facilitate yarn guidance, this application provides a fabric tension adjustment device.

[0007] This application provides a fabric tension adjustment device, which adopts the following technical solution:

[0008] A fabric tension adjusting device includes a fixed plate and a tensioning assembly disposed on the fixed plate for applying resistance to the yarn. The tensioning assembly includes a fixed shaft fixed to the fixed plate, an upper pressure plate and a lower pressure plate sleeved on the fixed shaft, an elastic element that applies pressure to the upper pressure plate, and an adjusting element that adjusts the elastic force of the elastic element. The upper pressure plate is disposed above the lower pressure plate, and the yarn passes between the upper pressure plate and the lower pressure plate. The elastic element is disposed above the upper pressure plate, and the adjusting element is threadedly connected to the fixed shaft. The lower end of the adjusting element abuts against the upper end of the elastic element.

[0009] Both ends of the fixed plate are provided with guide components for guiding the yarn. The guide components include two horizontal guides arranged vertically and two vertical guides arranged horizontally. The horizontal and vertical guides are arranged in a horizontal direction. The yarn passes through the two vertical guides and the two horizontal guides. A movable part is rotatably connected to the fixed plate. The horizontal guides located at the top are set on the movable part and move with the movable part.

[0010] By adopting the above technical solution, the yarn is guided by the cooperation of vertical and horizontal guides. When the yarn is placed between the horizontal and vertical guides, it is only necessary to move the upper horizontal guide away, thus eliminating the need for threading and making the yarn guiding process more convenient.

[0011] Optionally: the horizontal guide and the vertical guide are close to each other, the horizontal guide is disposed between the two end faces of the vertical guide, and the vertical guide is disposed between the two end faces of the horizontal guide.

[0012] By adopting the above technical solution, the yarn can be connected to both the horizontal and vertical guide members simultaneously, preventing the yarn from detaching from the horizontal and vertical guide members and ensuring a stable yarn guiding process.

[0013] Optionally: The movable part is provided with a limiting component to limit its rotation. The limiting component includes a hanging lug fixed to the movable part and a hanging ring rotatably connected to the fixed plate. The hanging rod can be sleeved on the hanging lug.

[0014] By adopting the above technical solution, the rotation of the moving part is limited by the limiting component, so that the position of the moving part is not easily changed, thereby making the horizontal guide on the moving part less likely to affect the guidance of the yarn.

[0015] Optionally: both the horizontal and vertical guides have guide grooves near the yarn, and the arcs of the guide grooves on the horizontal and vertical guides intersect each other in the projected view on the virtual surface perpendicular to the yarn conveying direction.

[0016] By adopting the above technical solution, the yarn can be located in the guide groove, so that the horizontal guide and the vertical guide are less likely to come into contact with the yarn at the same time, thereby reducing the wear of the horizontal guide and the vertical guide.

[0017] Optional: Both the vertical guide and the horizontal guide are made of ceramic.

[0018] By adopting the above technical solutions, the horizontal and vertical guide components are made smoother and have higher hardness, which increases the service life of the horizontal and vertical guide components and reduces yarn wear.

[0019] Optionally: The fixed plate has mounting grooves at the positions for mounting the horizontal and vertical guides. The mounting grooves penetrate the side wall of the fixed plate perpendicular to the yarn conveying direction. The mounting grooves also have snap-fit ​​grooves on the side wall parallel to the yarn conveying direction. The horizontal and vertical guides are respectively disposed in the mounting grooves and their ends away from the guide grooves are snapped into the snap-fit ​​grooves. The movable part also has mounting grooves, and one of the horizontal guides is disposed in the mounting groove on the movable part.

[0020] By adopting the above technical solution, both horizontal and vertical guide components can be replaced after wear or damage.

[0021] Optionally: Both the vertical guide and the horizontal guide are fitted with friction strips, which abut against the inner wall of the snap-fit ​​groove.

[0022] By adopting the above technical solution, the friction strip increases the friction between the vertical and horizontal guide components and the insertion groove, making it less likely for the vertical and horizontal guide components to fall out of the insertion groove and improving stability.

[0023] Optionally, both the horizontal and vertical guide members have disassembly grooves on their sidewalls perpendicular to the yarn conveying direction.

[0024] By adopting the above technical solution, when it is necessary to remove the horizontal guide and the vertical guide from the snap-fit ​​groove, force can be applied to the disassembly groove to drive the horizontal guide and the vertical guide to move, making it easier to remove the horizontal guide and the vertical guide from the snap-fit ​​groove.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. When guiding the yarn, a combination of vertical and horizontal guides is used. When placing the yarn between the horizontal and vertical guides, simply move the upper horizontal guide away, thus eliminating the need for threading and making the yarn guiding process more convenient.

[0027] 2. Both horizontal and vertical guide components can be replaced after wear or damage. Attached Figure Description

[0032] The present application will be further described in detail below with reference to the accompanying drawings.

[0033] This application discloses a fabric tension adjustment device, such as... Figure 1 As shown, the assembly includes a fixed plate 1, a tensioning component 2 disposed on the fixed plate 1 to apply resistance to the yarn, and a guide component 3 for guiding the movement direction of the yarn. The guide components 3 are respectively disposed on both sides of the tensioning component 2. The tensioning component 2 includes a fixed shaft 21 mounted on the fixed plate 1, a lower pressure plate 23 sleeved on the fixed shaft 21, an upper pressure plate 22, an elastic element 24 that applies downward pressure to the upper pressure plate 22, and an adjusting element 25 that adjusts the elastic force of the elastic element 24. The upper pressure plate 22 and the lower pressure plate 23 are bowl-shaped, and the openings of the upper pressure plate 22 and the lower pressure plate 23 face opposite directions. The lower pressure plate 23 is disposed below the upper pressure plate 22. Both the upper and lower pressure plates 23 can be extended along the fixed shaft 21, and the yarn passes between the upper pressure plate 22 and the lower pressure plate 23. In this embodiment, the elastic element 24 is a spring. The lower end of the elastic element 24 abuts against the upper pressure plate 22. The adjusting element 25 is threaded to the upper end of the fixed shaft 21, and the lower end of the adjusting element 25 abuts against the upper end of the elastic element 24. By adjusting the position of the adjusting element 25 on the fixed shaft 21, the magnitude of the elastic force applied by the elastic element 24 to the upper pressure plate 22 is adjusted, thereby adjusting the pressure applied by the upper pressure plate 22 to the yarn, thus adjusting the magnitude of the friction force on the yarn and achieving the effect of yarn tension.

[0034] Both ends of the fixed plate 1 are provided with upwardly extending extension plates 11. Guide components 3 are respectively disposed on the extension plates 11. The guide components 3 include two horizontal guides 32 arranged vertically and two vertical guides 31 arranged horizontally. Both the horizontal guides 32 and the vertical guides 31 are made of ceramic. An installation groove 12 is provided through the side wall of the extension plate 11 perpendicular to the yarn conveying direction. The installation groove 12 passes through the upper end face of the extension plate 11. A snap-fit ​​groove 13 is provided on the vertical inner wall of the installation groove 12. One end of the vertical guide 31 is inserted into the snap-fit ​​groove 13, and the other end of the vertical guide plate is located in the installation groove 12. The two vertical guide plates correspond to each other. A snap-fit ​​groove 13 is also provided on the horizontal side wall of the installation groove 12. One end of the horizontal guide 32 is embedded in the snap-fit ​​groove 13 on the horizontal side wall of the installation groove 12, and the horizontal guide rod is disposed on the side of the vertical guide rod away from the tensioning component 2. The upper end of the extension plate 11 is also rotatably connected to a movable part 14. The length of the movable part 14 is equal to the length of the extension plate 11. A snap-fit ​​groove 13 is also provided on the end face of the movable part 14 near the mounting groove 12. The end of a horizontal guide 32 away from the yarn is snapped into the snap-fit ​​groove 13 on the movable part 14. Two horizontal guides 32 are arranged opposite to each other, and the ends of the two horizontal guides 32 away from the snap-fit ​​groove 13 are both set in the mounting groove 12.

[0035] like Figure 2 As shown, the movable part 14 is provided with a limiting component 4 to limit its own rotation. The limiting component 4 includes a hanging ear 42 fixed on the movable part 14 and a hanging ring 41 rotatably connected to the extension plate 11. The hanging ear 42 is located at the end of the movable part 14 away from its own rotation axis. The hanging ring 41 can rotate and be sleeved on the hanging ear 42, so that the movable part 14 no longer rotates, thereby limiting the relative position of the horizontal guide 32 and the vertical guide 31.

[0036] like Figure 1 As shown, the horizontal guide 32 has the same thickness as the vertical guide 31, and the distance between the horizontal guide 32 and the vertical guide 31 is less than the thickness of the horizontal guide 32. The end of the horizontal guide 32 away from the snap-fit ​​groove 13 is located between the two end faces of the vertical guide 31, and the end of the vertical guide 31 away from the snap-fit ​​groove 13 is located between the two end faces of the horizontal guide 32. When the yarn passes between the horizontal guide 32 and the vertical guide 31, the yarn can always abut against the horizontal guide 32 and the vertical guide 31.

[0037] like Figure 3As shown, in order to prevent the vertical guide 31 and the horizontal guide 32 from falling out of the snap-fit ​​groove 13, tool grooves are provided on the side walls of the horizontal guide 32 and the vertical guide 31 within the snap-fit ​​groove 13. A friction strip 33 is fitted inside the tool groove. In this embodiment, the friction strip 33 is made of rubber. The friction strip 33 can abut against the inner wall of the snap-fit ​​groove 13, thereby increasing the friction between the vertical guide 31 and the horizontal guide 32 and the snap-fit ​​groove 13, making it difficult for the vertical guide 31 and the horizontal guide 32 to fall out of the snap-fit ​​groove 13.

[0038] After prolonged use, the surfaces of the horizontal guide 32 and the vertical guide 31 will wear down, requiring them to be removed from the locking groove 13. Since both the horizontal guide 32 and the vertical guide 31 are made of ceramic and are relatively smooth, a disassembly groove 34 is provided on both side walls of the horizontal guide 32 and the vertical guide 31 perpendicular to the yarn conveying direction. By applying force to the disassembly groove 34, the horizontal guide 32 and the vertical guide 31 can be removed from the locking groove 13 and replaced.

[0039] To further enhance the guiding effect of the vertical guide 31 and the horizontal guide 32 on the yarn, guide grooves 35 are provided on the end faces of the horizontal guide 32 and the vertical guide 31 away from the snap-fit ​​groove 13. The guide grooves 35 penetrate the side walls of the horizontal guide 32 and the vertical guide 31 perpendicular to the yarn conveying direction. The guide grooves 35 are semi-circular, and the arcs of the guide grooves 35 on the horizontal guide 32 and the vertical guide 31 intersect each other in the projection view on the virtual surface perpendicular to the yarn conveying direction. Thus, when the yarn is located on the vertical guide 31 and the horizontal guide 32, the yarn can be located within the guide grooves 35 and is less likely to be located between the vertical guide 31 and the horizontal guide 32, reducing the frictional force exerted on the yarn by the horizontal guide 32 and the vertical guide 31.

[0040] The implementation principle of this embodiment is as follows: After rotating the hanging ring 41 away from the hanging ear 42, the movable part 14 is rotated away from the extension plate 11, so that the horizontal guide located above is away from the mounting groove 12. After the yarn passes through the mounting groove 12, it passes between the upper pressure plate 22 and the lower pressure plate 23. Then the yarn passes through another mounting groove 12. After the movable part 14 is rotated towards the mounting groove 12, the movable part 14 abuts against the upper end of the extension plate 11. The hanging ring 41 is rotated to connect with the hanging ear 42.

[0041] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
