Description

Technical Field

[0001] This utility model relates to the field of textile equipment accessories technology, and in particular to a yarn frame for fixing yarn frames. Background Technology

[0002] Yarn winding racks are primarily used to wind yarn and then feed it to automated equipment, serving as a yarn supply system for textile machinery. Previously, yarn winding racks were made of wood, making them heavy and inconvenient for operators to handle. Current yarn winding racks are mainly supported by plastic and metal frames, and some are even equipped with drive motors. While these are heavier and more convenient to use, they also increase manufacturing costs.

[0003] Meanwhile, the existing yarn frame's outer metal frame is fixed on the central support shaft, making it difficult to deflect and keeping the yarn frame's outer diameter fixed. This makes it difficult to meet the winding needs of different yarns in daily use, thus requiring further improvement.

[0004] Therefore, a new technical solution is urgently needed to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a yarn frame for fixing yarn frames, so as to overcome the defects mentioned in the background art.

[0006] A yarn frame for fixing a yarn frame includes a shaft body, a coaxial spindle rotatably connected inside the shaft body, and further includes:

[0007] A fixed disk, comprising two disks respectively fixedly connected to both ends of the shaft body;

[0008] A winding frame, comprising a plurality of equally spaced members surrounding the shaft, each winding frame comprising two legs and a frame connecting the legs, wherein the two legs are rotatably connected to the end face of a fixed plate, and the axis of rotation is parallel to the axis of the shaft.

[0009] The end cap includes two end caps that are opposite to the fixed plate and are respectively located outside the fixed plate and fitted onto the shaft. One end of the end cap is provided with a cavity that houses the fixed plate. A limiting groove corresponding to the leg and allowing the leg to pass through is opened on the circumferential side wall of the cavity.

[0010] The positioning disk includes at least one corresponding to the end cover and is disposed on the outside of the end cover. The positioning disk is fixedly connected to the shaft or the fixed disk, and the fixed disk has gear teeth on its circumferential surface.

[0011] The locking structure includes two corresponding positioning discs, which are respectively disposed at the end of the end cover and are elastically abutted against the gear teeth of the positioning discs to lock the position of the end cover and the positioning discs.

[0012] Furthermore, the locking structure includes a mounting groove radially formed along the end cover, a pin axially connected within the mounting groove, one end of the pin extending toward the gear of the positioning disk to abut against the gear, and the other end extending toward the outside of the end cover to form a pulling end. The locking structure also includes an elastic element disposed within the mounting groove, the elastic element abutting against the pin to provide an elastic force to the pin toward the positioning disk.

[0013] Furthermore, a protrusion is formed on the side of the end cap, and the mounting groove is formed on the protrusion.

[0014] Furthermore, a pull ring is rotatably connected to the pulling end.

[0015] Furthermore, a connecting portion that bends inward is provided on the leg;

[0016] The fixed plate end face is provided with connecting holes that are equally spaced and correspond to the connecting parts respectively. The connecting parts pass through and are rotatably connected to the connecting holes. A limit block is provided on the fixed plate end face and on one side of each connecting hole to abut against the surface of one side of the leg.

[0017] Furthermore, the limiting block includes a main body, a limiting wall extending in a radial direction is provided on one side of the main body facing the connecting hole, and a reinforcing portion protruding in a direction away from the connecting hole is formed on the side of the main body facing away from the connecting hole.

[0018] Furthermore, each end of the shaft is provided with a fixed connection part, and at least one limiting plane is formed on the circumferential surface of the fixed connection part. The fixed plate is provided with a limiting through hole on the fixed connection part along the axis, and the inner wall of the limiting through hole is provided with a planar inner wall that matches the limiting plane.

[0019] Furthermore, the cavity is provided with a through hole for the fixing part to pass through, and a boss protruding towards the fixing plate is formed on the inner wall of the cavity. The boss abuts against the end face of the fixing plate and defines a gap space between the end face of the fixing plate and the bottom of the cavity for the leg to pass through.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] During use, the two ends of the mandrel are rotatably mounted on the textile equipment, allowing the mandrel to rotate. When it is necessary to adjust the outer diameter defined by the winding frame for different yarns, if the winding frame cannot rotate with the mandrel when held, or if the end cap is locked, rotating the mandrel will drive the fixed plate to rotate. At this time, the rotation of the fixed plate and the end cap, which are interlocked, causes the legs of the winding frame to rotate relative to the end cap, thus positioning the legs in the fixed plate. The bending of the section between the disc and the end cap reduces the overall length of the winding frame located outside the end cap, thereby reducing the radius of the edge defined by the winding frame body. This changes the overall size of the winding frame to accommodate different yarn windings. After the outer diameter is fixed, the locking structure contacts the gear teeth of the positioning disc, thereby locking the position of the positioning disc and the end cap, that is, locking the relative position of the end cap and the shaft. This ensures that the adjusted outer diameter of the winding frame is maintained and fixed, thus ensuring the stability of the winding frame during yarn winding.

[0022] This utility model embodiment provides a yarn frame for fixing yarn frames. Multiple winding frames pass through the limiting groove of the end cover and are rotatably connected to the fixed plate. After the winding frame is held, the rotating shaft drives the fixed plate to rotate, thereby causing the winding frame to deflect. This causes the portion of the winding frame located within the fixed plate and end cover to bend, thereby reducing the outer diameter defined at the end of the winding frame. The fixed plate and the bottom cover are fixed by a locking structure cooperating with the positioning plate, thus fixing the winding frame and maintaining the defined outer diameter size. This can meet the needs of winding different yarns and fix the defined outer diameter size of the winding frame, improving stability.

[0034] This utility model embodiment provides a yarn frame for fixing yarn frames. Multiple winding frames 300 pass through the limiting grooves 411 of the end cover 400 and are rotatably connected to the fixing plate 200 by their legs 310. After the winding frame 300 is held, the rotating shaft 100 drives the fixing plate 200 to rotate, thereby causing the winding frame 300 to deflect. This causes the portion of the winding frame located within the fixing plate 200 and the end cover 400 to bend, thereby reducing the outer diameter defined at the end of the winding frame 300. The fixing plate 200 and the bottom cover are fixed by a locking structure cooperating with the positioning plate 500, thereby fixing the winding frame 300 and maintaining the defined outer diameter size. This can meet the needs of winding different yarns and fix the defined outer diameter size of the winding frame 300, improving stability.

[0035] In this technical solution, such as Figure 1-7As shown, this embodiment provides a yarn frame for fixing yarn frames, including a shaft 100, with a coaxial spindle 110 rotatably connected inside the shaft 100, and also including a fixing plate 200, a winding frame 300, an end cap 400, a positioning plate 500, and a locking structure. Specifically, the fixing plate 200 includes two that are respectively fixedly connected to both ends of the shaft 100; the winding frame 300 includes a plurality of winding frames that are equally spaced around the shaft 100, and each winding frame 300 includes two legs 310 and a frame 320 connected between the legs 310, and the two legs 310 are respectively rotatably connected to the end face of the fixing plate 200, and the axis of rotation is parallel to the axis of the shaft 100; the end cap 400 includes two that are opposite to the fixing plate 200, and are respectively located at... The fixed plate 200 is fitted onto the shaft 100. One end of the end cover 400 is provided with a cavity 410 that houses the fixed plate 200. A limiting groove 411 corresponding to the leg 310 and allowing the leg 310 to pass through is provided on the circumferential side wall of the cavity 410. The positioning plate 500 includes at least one corresponding to the end cover 400 and is provided on the outside of one of the end covers 400. The positioning plate 500 is fixedly connected to the shaft 100 or the fixed plate 200, and gear teeth 501 are provided on the circumferential surface of the fixed plate 200. The locking structure includes at least one corresponding to the positioning plate 500 and is provided at the end of the end cover 400. It is used to elastically abut against the gear teeth 501 of the positioning plate 500 to lock the position of the end cover 400 and the positioning plate 500.

[0036] During use, the two ends of the mandrel 110 are rotatably mounted on the textile equipment, allowing the shaft 100 to rotate. When it is necessary to adjust the outer diameter defined by the winding frame 300 for different yarns, the winding frame 300 can be held to prevent it from rotating with the shaft 100, or the end cap 400 can be locked. Rotating the shaft 100 will then drive the fixed plate 200 to rotate. At this time, the fixed plate 200 and the end cap 400 rotate alternately, causing the legs 310 of the winding frame 300 to be rotatably connected to the fixed plate 200 to deflect relative to the end cap 400, thereby causing the legs 310 to be positioned in the fixed plate 200. The portion between the fixed plate 200 and the end cap 400 bends, causing the overall length of the winding frame 300 located outside the end cap 400 to decrease. This reduces the radius of the edge defined by the frame 320 of the winding frame 300, changing the overall size of the winding frame 300 to accommodate different yarn windings. After fixing the outer diameter, the locking structure contacts the gear teeth 501 of the positioning plate 500, thereby locking the position of the positioning plate 500 and the end cap 400, that is, locking the relative position of the end cap 400 and the shaft 100. This allows the adjusted outer diameter of the winding frame 300 to be maintained and fixed, ensuring the stability of the yarn frame during yarn winding.

[0037] like Figure 3-7 As shown, specifically, the locking structure includes a mounting groove 401 radially opened along the end cover 400. A pin 420 is disposed within the mounting groove 401 and axially movably connected thereto. One end of the pin 420 extends towards the gear of the positioning disk 500 to abut against the gear, while the other end extends outwards from the end cover 400 to form a pulling end 421. The locking structure also includes an elastic element 430 disposed within the mounting groove 401. The elastic element 430 abuts against the pin 420 to provide an elastic force to the pin 420 in the direction of the positioning disk 500. To facilitate pulling the pin, a pull ring (not shown in the figure) is rotatably connected to the pulling end 421.

[0038] To improve the fit with the positioning disc 500, a protrusion 402 is formed on the side of the end cover 400, and a mounting groove 401 is formed on the protrusion 402. That is, the protrusion 402 allows the mounting groove 401 to protrude from the surface of the end cover 400, better aligning with the gear teeth 501. This facilitates the pin 420's elastic engagement with the gear teeth 501 under the elastic thrust of the elastic element 430, locking the positioning disc 500. When releasing the positioning disc 500, pulling the pin 420's pulling end 421 separates the pin 420 from the gear teeth 501, thus releasing the relative position between the end cover 400 and the positioning disc 500 or the shaft 100, allowing for the winding frame 30 to be adjusted. Adjustments are made to 0. In this embodiment, in order to keep the pin released from the positioning plate, the pull ring is rotated to swing towards the protrusion, so that the free end of the pull ring can abut against the end of the protrusion. Under the action of elastic force, the pull ring and the protrusion maintain a contact relationship. At this time, by setting the diameter of the pull ring, the length of the pin, and the length of the protrusion, the abutting end of the pin can remain separated from the gear teeth when the pull ring and the protrusion are in contact, so that the pin remains released from the positioning plate.

[0039] In this embodiment, in order to adjust the winding frame 300, the portion of the leg 310 located between the fixing plate 200 and the end cap 400 is bent, such as... Figure 3-6 As shown, a connecting part 311 that bends inward is provided on the leg part 310; a connecting hole 201 that is equally spaced at an angle and corresponds to the connecting part 311 is provided on the end face of the fixing plate 200; the connecting part 311 passes through and is rotatably connected to the connecting hole 201; and a limiting block 202 is provided on the end face of the fixing plate 200 and on one side of each connecting hole 201 to abut against one side surface of the leg part 310.

[0040] During the adjustment of the winding frame 300, when the shaft 100 drives the fixed disk 200 to rotate, the relative position of the end cap 400 remains fixed. When the fixed disk 200 rotates, the leg 310 is pushed to deflect due to the limiting groove of the fixed end cap 400, causing the leg 310 located between the fixed disk 200 and the end cap 400 to bend. This adjusts the outer diameter of the cylinder defined at the end of the winding frame 300. To restrict the rotation direction of the shaft, allowing it to rotate only in one direction to adjust the diameter of the cylinder defined at the end of the winding frame, a limiting block is provided on the fixed disk. When the shaft rotates in the opposite direction, one side of the limiting block 202 abuts against the side wall of the leg 310, thus blocking the leg of the winding frame and preventing it from rotating in the opposite direction.

[0041] In this embodiment, in order to ensure that the limiting block 202 has sufficient strength during the adjustment of the winding frame 300, such as Figure 6 As shown, the limiting block 202 includes a main body 2021. A limiting wall 2022 extending in the radial direction is provided on one side of the main body 2021 facing the connection hole 201, and a reinforcing part 2023 protruding in the direction away from the connection hole 201 is formed on the other side of the main body 2021 facing away from the connection hole 201.

[0042] In this embodiment, the shaft 100 and the fixed disk 200 are fixedly connected by a limiting structure, thereby enabling the fixed disk 200 to rotate along with the shaft 100. Specifically, as shown below... Figure 7 As shown, the shaft 100 has a fixed connection portion 120 at each end. At least one limiting plane 121 is formed on the circumferential surface of the fixed connection portion 120. The fixed disk 200 is coaxially provided with a limiting through hole 210 that is fitted onto the fixed connection portion 120. The inner wall of the limiting through hole 210 is provided with a planar inner wall 211 that matches the limiting plane 121. Through the mutual cooperation of the limiting plane 121 and the planar inner wall 211, the fixed disk 200 can rotate with the shaft 100, and the fixed connection is achieved by means of interference fit or other methods.

[0043] In this embodiment, in order to allow the leg 310 to have sufficient space to move between the fixed plate 200 and the end cap 400, a through hole for the fixing part 120 to pass through is provided inside the cavity 410, and a boss 412 protruding towards the fixed plate 200 is formed on the inner wall of the cavity 410. The boss 412 abuts against the end face of the fixed plate 200 and defines a gap space between the end face of the fixed plate 200 and the bottom of the cavity 410 for the leg 310 to pass through.

[0044] For those skilled in the art, various other corresponding changes and modifications can be obtained based on the structure and principles disclosed in this utility model, and all such changes and modifications fall within the protection scope of this utility model.
