Description

Technical Field

[0001] This utility model relates to the field of tensioner technology, specifically to an installation structure and a tensioner. Background Technology

[0002] Tensioners are key devices used in the textile industry in conjunction with warping machines. They are mainly used to control the tension of yarn during the warping process, ensuring uniform yarn arrangement and consistent tension, thereby improving the quality and efficiency of subsequent weaving processes. During warping, the yarn is drawn from the bobbin, adjusted by the tensioner, and then wound onto the warp beam with a constant tension.

[0003] Tensioners are typically equipped with mounting structures to attach them to the target rod. Figure 1 An installation structure for a tensioner in the prior art is shown. A bayonet 200 is provided on the base 100 of the tensioner. Two clamping edges 300 at a certain angle are formed on the left side of the bayonet 200, and a clamping screw 400 is provided on the right side of the bayonet 200. When the target rod 500 is placed within the bayonet 200, rotating the clamping screw 400 tightens the right side of the target rod 500, while the left side is supported and limited by the two clamping edges 300, thereby fixing the tensioner. However, this installation structure has poor adaptability, only suitable for round rods; if the target rod 500 is a square rod, it is difficult to stably install the tensioner on the square rod.

[0036] Example 1:

[0037] like Figure 2-6As shown, this embodiment provides an installation structure for fixing a tensioner or similar device to a target rod. Specifically, the installation structure includes a base 1 and a fixing member 2. The base 1 is the main housing of the tensioner or similar device. A pressing plane 11 and a pressing groove 12 are formed on the base 1, with the pressing groove 12 recessed from the pressing plane 11. The fixing member 2 is movably connected to the base 1. The fixing member 2 can move away from the pressing plane 11 and the pressing groove 12 to accommodate the target rod, and can also move close to the pressing plane 11 and the pressing groove 12 to cooperate with the pressing plane 11 or the pressing groove 12 to press the target rod, thus clamping and fixing the tensioner or similar device to the target rod.

[0038] During installation, the target rod is positioned between the fixing member 2 and the pressing plane 11. One side of the target rod is pressed by the fixing member 2, and the other side is supported and limited by the pressing plane 11. The pressing plane 11 is used to adapt to a target rod. For example, when the target rod is a square rod with a square outer profile, it has two opposing planes. One plane is pressed by the fixing member 2, and the other plane is in contact with the pressing plane 11.

[0039] Alternatively, the target rod can be positioned between the fixing member 2 and the clamping groove 12, with one side of the target rod clamped by the fixing member 2 and the other side supported and limited by the clamping groove 12. The clamping groove 12 is used to adapt to another target rod; for example, when the target rod is a round rod with a circular cross-section, one side of its arc surface is clamped by the fixing member 2, and the opposite side is supported and limited by the clamping groove 12. The clamping groove 12 is preferably an arc-shaped groove, where the arc surface of the round rod fits against the arc-shaped groove, increasing the contact area and enabling better fixation; alternatively, the clamping groove 12 can also be formed as a triangular groove, i.e., ... Figure 1 The diagram shows two clamping edges at a certain angle, which together limit the load on the round rod.

[0040] In other embodiments, the outer contour of the target rod can also be other shapes. The shape of the clamping groove 12 can be adapted as needed, and the clamping can be performed by either the clamping plane 11 or the clamping groove 12 as needed.

[0041] Thus, the installation structure provided in this embodiment has a pressing plane 11 and a pressing groove 12 on the base 1. The pressing plane 11 can be used to fit target rods such as square rods, and the pressing groove 12 can be used to fit target rods such as round rods. Both can be reliably fixed and installed, and the installation adaptability is better.

[0042] Preferably, the clamping groove 12 is located in the middle of the clamping plane 11, for example, at the exact center. This allows for a smaller clamping space for various target rods, and the dimensions of the base 1 and the fixing member 2 can be reduced accordingly.

[0043] Preferably, the fixing member 2 in this embodiment includes a fixing plate 21 and a fixing pin 22. The fixing plate 21 is movably connected to the base 1. The fixing plate 21 can move away from and towards the pressing plane 11 and the pressing groove 12 to achieve avoidance and pressing. The fixing pin 22 may be, but is not limited to, an internal hexagon screw, which is threaded to the middle of the fixing plate 21 and is disposed through the fixing plate 21.

[0044] The fixing plate 21 is provided corresponding to the pressing plane 11. One side of the target rod can be pressed by the fixing plate 21, and the other side is supported and limited by the pressing plane 11, for example, when the target rod is a square rod. The fixing pin 22 is provided corresponding to the pressing groove 12. One side of the target rod can be pressed by the fixing pin 22, and the other side is supported and limited by the pressing groove 12, for example, when the target rod is a round rod. Assuming the target rod is a square rod and the distance between the two pressed surfaces is 20mm, it can be pressed by the fixing plate 21 and the pressing plane 11. If the target rod is a round rod with a diameter of 20mm, since the pressing groove 12 is recessed relative to the pressing plane 11, a positioning pin can be provided. The positioning pin can be screwed into the pressing groove 12 relative to the fixing plate 21, thereby pressing the round rod.

[0045] In other embodiments, the fastener 2 may also be... Figure 1 As shown, the fixing element 2 is a screw, which is threaded into the base 1 and can be screwed in and out relative to the pressing plane 11 and the pressing groove 12. Various target rods are pressed by the screw, which is the fixing element 2.

[0046] Preferably, in this embodiment, a pressing protrusion 211 is formed in the middle of the fixing plate 21, and the fixing plate 21 presses the target rod through the pressing protrusion 211. The pressing protrusion 211 can be adapted to the size of the target rod for reliable pressing; and the area of ​​the pressing protrusion 211 is relatively small, which can prevent uneven pressing caused by local unevenness in the large area of ​​the fixing plate 21. The base 1 and the fixing member 2 are preferably made of plastic. In order to improve the thread strength and durability, the fixing plate 21 is also provided with a metal insert 212 that is threaded with the fixing pin 22.

[0047] In this embodiment, an extension arm 13 is formed on the side of the receiving space of the target rod on the base 1. One end of the fixing plate 21 is rotatably connected to the extension arm 13, and the other end is detachably connected to the base 1. A connecting arm 14 is also formed on the other side of the receiving space of the target rod on the base 1. The other end of the fixing plate 21 is connected to the connecting arm 14 by screws. A metal locking piece 15 is also fixedly fitted inside the connecting arm 14. The metal locking piece 15 has a threaded hole that mates with the screws, which improves the connection effect and service life. In other embodiments, the extension arm 13 can also be provided with a metal locking piece 15 for connection, that is, both ends of the fixing plate 21 are fixed by screws. Compared with this connection method, in this embodiment, one end of the fixing plate 21 is hinged to the base 1, which makes installation and disassembly more convenient, and there is no problem of the fixing plate 21 being lost.

[0048] As can be seen from the above, the installation structure provided in this embodiment has better installation adaptability, enabling devices such as tensioners to be reliably installed on various target rods, and the installation is also very convenient.

[0049] Example 2:

[0050] This embodiment provides a tensioner, which includes an installation structure as described in Embodiment 1, and is installed on a target rod through the installation structure; multiple tensioners can be vertically fixed sequentially on a target rod.

[0051] like Figure 2-7 As shown, the tensioner in this embodiment includes the base 1, on which a partition 16 is integrally formed. Compared with a split partition, this reduces the number of parts, assembly steps, and assembly errors. The partition 16 is provided with an inlet component 17, such as an inlet for ceramic eyes. The base 1 is also equipped with a pretensioning component 3 and a tensioning component 4.

[0052] Furthermore, the pretension assembly 3 includes yarn guides 31 such as yarn guides fixedly mounted on the base 1. The yarn guides 31 are fixed to the base 1 by screws. A lower pressure sheet 32, an upper pressure sheet 33, and a counterweight sheet 34 are sequentially fitted onto the yarn guides 31. A U-shaped groove 311 is formed on the yarn guides 31 to allow the yarn to pass through. The yarn is introduced from the inlet 17 in the partition 16, passes between the lower pressure sheet 32 ​​and the upper pressure sheet 33, is provided with a certain pretension, passes through the U-shaped groove 311 on the yarn guides 31, and then passes through the tension assembly 4 before being led out to the warping machine.

[0053] Furthermore, the base 1 has a mounting plane 18 for mounting the tension assembly 4, and a protruding ring 181 is formed on the mounting plane 18. The tension assembly 4 is mounted inside the protruding ring 181. The tension assembly 4 includes an upper yarn guide wheel seat 41 and a lower yarn guide wheel seat 44, both of which are preferably circular plates. A plurality of yarn guide rods are provided between the upper yarn guide wheel seat 41 and the lower yarn guide wheel seat 44, and the yarn is wound around the outer periphery of these yarn guide rods. The upper surface of the lower yarn guide wheel seat 44 is coplanar with the upper surface of the protruding ring 181.

[0054] In this embodiment, a convex ring 181 is provided on the mounting plane 18. A mounting space of a certain size is formed inside the convex ring 181, and the upper surface of the convex ring 181 is coplanar with the upper surface of the lower guide wheel seat 44 in the tension assembly 4. There is only a small rotational gap between the lower guide wheel seat 44 and the convex ring 181. When the warp beam of the warping machine suddenly stops, the tension assembly 4 will continue to operate for a period of time. Even if the yarn wrapped around the outer periphery of the tension assembly 4 becomes loose, it will not move below the lower guide wheel seat 44. When the warp beam starts again, the yarn can continue to move around the tension assembly 4 without breaking. Furthermore, this embodiment only provides a small convex ring 181, which is easy to manufacture using molds or other methods.

[0055] Preferably, in this embodiment, the upper surface of the convex ring 181 and the upper surface of the lower guide roller seat 44 are both inclined at a certain angle towards the yarn inlet side, for example, 2-3 degrees. This facilitates the smooth entry of the yarn from the inlet side into the tension assembly 4, and prevents the yarn from contacting the top edge of the convex ring 181 near the yarn inlet side, thus preventing damage to the yarn and affecting its tension. In addition, by setting the inclination angle, impurities such as lint and fibers can slide directly off or slide off under vibration onto the mounting plane 18 outside the convex ring 181. Since the convex ring 181 occupies a small proportion of the mounting plane 18, the mold structure can be simplified, making it easier to manufacture, and allowing impurities such as lint and fibers to fall onto the mounting plane 18 outside the convex ring 181 more quickly.

[0056] The tension assembly 4 in this embodiment also includes a hysteresis device 47. The center of the upper guide wheel seat 41 is connected to the rotating shaft 48 of the hysteresis device 47, for example, by direct fixation or by means of pins, keys, etc. An inclined mounting surface 182 is recessed on the mounting plane 18 inside the convex ring 181. A mounting base 183 is mounted on the inclined mounting surface 182. The lower guide wheel seat 44 is connected to the mounting base 183 via a bearing 184, such that the centerline of the lower guide wheel seat 44 is inclined at a certain angle relative to the centerline of the upper guide wheel seat 41. Through holes are provided on the mounting base 183 and the mounting plane 18 to allow the rotating shaft 48 to pass through.

[0057] Furthermore, the yarn guide rod includes a plurality of upper yarn guide rods 42 and lower yarn guide rods 45 arranged sequentially at intervals. For example, each upper yarn guide rod 42 is adjacent to two lower yarn guide rods 45, and each lower yarn guide rod 45 is adjacent to two upper yarn guide rods 42. The upper yarn guide rods 42 are distributed circumferentially along the upper yarn guide wheel seat 41. One end of each upper yarn guide rod 42 is fixedly connected to the upper yarn guide wheel seat 41, and the other end is inclined outward at the same preset angle, for example, 3-7 degrees. A corresponding lower movable hole 46 is provided on the lower yarn guide wheel seat 44, and the other end of each upper yarn guide rod 42 extends into the lower movable hole 46 on the lower yarn guide wheel seat 44. The lower guide rods 45 are distributed circumferentially along the lower guide wheel seat 44. One end of each lower guide rod 45 is fixedly connected to the lower guide wheel seat 44, and the other end is inclined inward at a set angle, for example, 3-7 degrees. A corresponding upper movable hole 43 is provided on the upper guide wheel seat 41, and the other end of each lower guide rod 45 extends into the upper movable hole 43 on the upper guide wheel seat 41. In this way, the yarn can spiral upward along the outer circumference of each guide rod during movement, and it ensures that when the yarn winds around the outer circumference of each guide rod, it will not detach directly from above or below.

[0058] The hysteresis 47 is mounted on the bottom of the mounting plane 18 inside the convex ring 181 by means of mounting screws. The mounting plane 18 inside the convex ring 181 has a countersunk hole 185 corresponding to the mounting screws; this does not affect the setting of the mounting base 183.

[0059] The tensioner also includes a bottom cover 5, and a control board 54 is installed inside the bottom cover 5. The control board 54 is horizontally arranged at the bottom of the hysteresis 47. The hysteresis 47 is electrically connected to the control board 54 and is controlled by the control board 54 to operate in order to generate appropriate tension.

[0060] In existing tensioners, the control board 54 is typically positioned vertically to the side of the hysteresis coil 47, for example... Figure 7 On the right side of the tensioner. Compared with the prior art, the tensioner in this embodiment places the control board 54 at the bottom of the hysteresis coil 47. The size of the control board 54 can be set to be larger, allowing for functional expansion as needed and facilitating the arrangement of components on the control board 54. Furthermore, a speed detection sensor can be easily installed on the control board 54 to detect the speed of the hysteresis coil 47, thereby detecting problems such as wire breakage. In addition, space is reserved on the side of the hysteresis coil 47 to facilitate cable arrangement and the addition of other components.

[0061] The bottom cover 5 is preferably made of metal, and more preferably of a non-magnetic material such as aluminum, to reduce interference with the hysteresis device 47. The metal material of the bottom cover 5 allows heat from the tensioner to dissipate quickly, especially the control plate 54 mounted on the bottom cover 5, whose heat can be directly and rapidly dissipated through the bottom cover 5. Several nut posts 53 can be provided on the bottom surface of the bottom cover 5 to support the control plate 54, with corresponding through holes on the control plate 54 for installation with screws; the nut posts 53 can be fixed to the bottom cover 5 by riveting or other methods. The base 1 is preferably made of plastic, which is lightweight, low-cost, and easy to manufacture.

[0062] Furthermore, in this embodiment, the outer edge of the bottom surface of the bottom cover 5 is bent towards the base 1 to form a flange 51. The inner side of the flange 51 and the bottom surface of the bottom cover 5 form the mounting space for the control board 54. In this way, in addition to the bottom of the control board 54, the heat around the control board 54 can also be dissipated outwards more quickly. The flange 51 is also bent outwards to form a mounting edge 52. The mounting edge 52 is provided with multiple mounting holes 521. A plurality of connecting posts 19 are correspondingly formed in the base 1. The mounting can be connected to the connecting posts 19 by screws passing through the mounting holes 521 for installation.

[0063] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
