Abstract

This utility model relates to the field of spandex yarn production and storage technology, specifically to a spandex yarn storage cylinder, including a bottom functional box and an arc-shaped adjustment plate. Several arc-shaped adjustment plates are evenly distributed circumferentially on the bottom functional box. The spandex yarn storage cylinder also includes a fixed cylinder fixedly installed on the bottom functional box. The fixed cylinder has a circumferentially circumferentially open opening in its center. In use, the several arc-shaped adjustment plates are adjusted by an adjustment mechanism to move synchronously on a guide rod. Due to the adjustment gap between adjacent arc-shaped adjustment plates, during the movement of the several arc-shaped adjustment plates, an elastic arc plate located on the back of the arc-shaped adjustment plate will also move synchronously, extending out of the adjustment gap. This allows the spandex yarn to be directly wound and stored on the surface of the elastic arc plate. If a momentary tension fluctuation occurs, the elastic arc plate will contract under force and be placed into the adjustment gap, thus completely preventing the spandex yarn from breaking.

Description

Technical Field

[0001] This utility model relates to the field of spandex yarn production and storage technology, and in particular to a spandex yarn storage tube. Background Technology

[0002] Modern textile production lines rely heavily on automated equipment. A suitable yarn unwinding design can ensure that spandex yarn can be smoothly unwound from the yarn unwinding device, thereby improving production efficiency. Therefore, using a suitable spandex yarn unwinding device is crucial for ensuring yarn quality and ease of use. Existing spandex yarn unwinding devices have expanded their applicability by adjusting the outer diameter.

[0003] For example, Chinese patent application number CN201821295187.2 discloses a storage tube for spandex yarn with an adjustable outer diameter. It includes a bottom functional box, a longitudinally placed external thread control rod mounted on the upper end of the bottom functional box, and a longitudinally placed stepper motor fixedly installed inside the bottom functional box. The longitudinally placed stepper motor controls the rotation of the longitudinally placed external thread control rod, thereby driving the upper and lower internal thread lifting cylinders to rise and fall in opposite directions. This changes the angle between the upper and lower internal connecting rods, thus changing the distance between the longitudinally placed arc-shaped adjustment plate and the upper and lower internal thread lifting cylinders. By adjusting the distance, the outer diameter of the entire storage tube can be changed, making the entire storage tube structure adjustable and greatly expanding its applicability. However, once the outer diameter of the entire storage tube is adjusted, the size is fixed and cannot adapt to the instantaneous tension fluctuations that frequently occur in practice, still resulting in spandex yarn breakage. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a spandex yarn storage tube to solve the technical problem that once the outer diameter of the entire storage tube is adjusted, the size is fixed and cannot adapt to the instantaneous tension fluctuations that often occur in practice, and the phenomenon of spandex yarn breakage still exists.

[0005] To achieve the above objectives, this utility model provides a spandex yarn storage tube, including a bottom functional box and an arc-shaped adjustment plate. Several arc-shaped adjustment plates are arranged circumferentially on the bottom functional box. The spandex yarn storage tube also includes:

[0006] A fixed cylinder is fixedly installed on the bottom functional box. A clearance opening is provided in the middle of the fixed cylinder. Guide rods are evenly distributed on the outer edge of the fixed cylinder. The arc-shaped adjusting plate is slidably disposed on the guide rods.

[0007] An adjustment gap is provided between adjacent arc-shaped adjustment plates, and an elastic arc plate is provided on the back of the arc-shaped adjustment plate, the elastic arc plate extending out of the adjustment gap;

[0008] An adjustment mechanism for adjusting the synchronous sliding of several of the arc-shaped adjustment plates on the guide rod.

[0009] Furthermore, both ends of the arc-shaped adjusting plate are detachably equipped with mounting heads, which are slidably mounted on the guide rod.

[0010] Furthermore, the adjustment mechanism includes:

[0011] A threaded rod threaded onto the fixed cylinder;

[0012] Rotate the movable seat mounted on the upper end of the threaded rod;

[0013] Several push-pull rods are hinged to the side of the movable seat, and the other end of the push-pull rods passes through the clearance opening and is hinged to the side wall of the arc-shaped adjustment plate.

[0014] Furthermore, an operation opening is provided on one side of the bottom of the bottom functional box, and a handwheel is installed at the lower end of the threaded rod, with the handwheel positioned within the range of the operation opening.

[0015] Furthermore, the threaded rod is positioned on the fixed cylinder by a fastening nut.

[0016] Furthermore, the elastic arc plate is provided with bolts, and the elastic arc plate can be detachably installed inside the arc-shaped adjustment plate by means of bolts.

[0017] Furthermore, the extension length of the plurality of elastic arc plates in the corresponding adjustment gap remains consistent.

[0018] Furthermore, the arc-shaped end faces of several of the aforementioned arc-shaped adjustment plates are located on the same circular surface.

[0019] The beneficial effects of this utility model are as follows: In use, the adjustment mechanism adjusts several arc-shaped adjustment plates to move synchronously on the guide rod. Since there is an adjustment gap between adjacent arc-shaped adjustment plates, during the movement of several arc-shaped adjustment plates, the elastic arc plate located on the back of the arc-shaped adjustment plate will also move synchronously, and the elastic arc plate will extend out of the adjustment gap, so that the spandex yarn can be directly wound and stored on the surface of the elastic arc plate. If there is an instantaneous tension fluctuation, the elastic arc plate will be forced to contract and be placed into the adjustment gap, thus completely avoiding the phenomenon of spandex yarn breakage.

[0029] The first aspect of this utility model proposes a spandex yarn storage tube, such as... Figure 1-4 As shown, the device includes a bottom functional box 1 and several arc-shaped adjustment plates 2, which are evenly distributed circumferentially on the bottom functional box 1. The spandex yarn storage tube also includes:

[0030] A fixed cylinder 3 is fixedly installed on the bottom functional box 1. An avoidance opening 4 is provided in the middle of the fixed cylinder 3. Guide rods 5 are evenly distributed on the outer edge of the fixed cylinder 3. The arc-shaped adjustment plate 2 is slidably mounted on the guide rods 5.

[0031] An adjustment gap 6 is provided between adjacent arc-shaped adjustment plates 2, and an elastic arc plate 7 is provided on the back of the arc-shaped adjustment plate 2, with the elastic arc plate 7 extending out of the adjustment gap 6;

[0032] An adjustment mechanism for adjusting the synchronous sliding of several arc-shaped adjustment plates 2 on the guide rod 5.

[0033] In this embodiment, when in use, according to the specific storage specifications of the spandex yarn, a matching arc-shaped adjustment plate 2 is selected and installed on the storage tube. Then, the adjustment mechanism is used to adjust several arc-shaped adjustment plates 2 to move synchronously on the guide rod 5. Since there is an adjustment gap 6 between adjacent arc-shaped adjustment plates 2.

[0034] During the operation of several arc-shaped adjustment plates 2, the elastic arc plate 7 located on the back of the arc-shaped adjustment plate 2 will also move synchronously, and the elastic arc plate 7 will extend out of the adjustment gap 6, so that the spandex yarn can be directly wound and stored on the surface of the elastic arc plate 7. If there is an instantaneous tension fluctuation, the elastic arc plate 7 will be forced to contract and be placed into the adjustment gap 6.

[0035] In this embodiment, as Figure 2 As shown, both ends of the arc-shaped adjusting plate 2 are detachably equipped with mounting heads 8. The mounting heads 8 are slidably mounted on the guide rod 5. By quickly replacing the appropriate arc-shaped adjusting plate 2 on the mounting head 8, it can better adapt to different roll widths and yarn types, and prevent edge collapse or yarn slippage.

[0036] In this embodiment, as Figure 2 As shown, the adjustment mechanism includes:

[0037] A threaded rod 9 is threaded onto a fixed cylinder 3;

[0038] Rotary mounting of movable seat 10 on the upper end of threaded rod 9;

[0039] Several push-pull rods 11 are hinged to the side of the movable seat 10, and the other end of the push-pull rod 11 passes through the clearance opening 4 and is hinged to the side wall of the arc-shaped adjustment plate 2.

[0040] An operating opening 12 is provided on one side of the bottom of the bottom function box 1. A handwheel 13 is installed at the lower end of the threaded rod 9. The handwheel 13 is located within the range of the operating opening 12. Specifically, the operator directly acts on the handwheel 13 through the operating opening 12. After rotating the handwheel 13, the threaded rod 9 is rotated. Then, through the movable seat 10 and the push-pull rod 11, the various arc-shaped adjustment plates 2 are driven to synchronously complete the expansion and contraction actions.

[0041] In this embodiment, as Figure 2 , Figure 3 As shown, the threaded rod 9 is positioned on the fixed cylinder 3 by the fastening nut 14. The fastening nut 14 is used to position the threaded rod 9 on the fixed cylinder 3 to prevent changes in the state of each arc-shaped adjusting plate 2.

[0042] In this embodiment, as Figure 4 As shown, the elastic arc plate 7 is provided with bolts, and the elastic arc plate 7 can be detachably installed inside the arc-shaped adjustment plate 2 by means of bolts.

[0043] In this embodiment, as Figure 4 As shown, the extension lengths of several elastic arc plates 7 in the corresponding adjustment gaps 6 are consistent.

[0044] In this embodiment, as Figure 1 As shown, the arc-shaped end faces of several arc-shaped adjustment plates 2 are located on the same circular surface.
