Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of wire reels, and in particular to a detachable winding structure. Background Technology
[0002] Synthetic yarn is a man-made thread made by processing polymer raw materials such as PET and PP into fibers, and it is widely used in the textile industry.
[0003] The general process for producing synthetic yarn includes sandblasting, texturing, twisting, setting, and unwinding. Each of these processing steps requires a large number of rolls, which are currently made of paper. However, using paper rolls has the following drawbacks: due to their poor strength and disposable nature, the cost of paper rolls constitutes a significant proportion of the total production material cost. Therefore, to address these shortcomings, this application proposes a reusable, detachable winding structure to replace paper rolls. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a reusable detachable winding structure that can replace paper tubes.
[0005] The objective of this utility model is achieved through the following technical solution:
[0006] A detachable winding structure, comprising:
[0007] The outer cylinder, wherein the outer cylinder has a non-closed rolled structure; and
[0008] The tensioning assembly includes a central column and two tensioning members, which are respectively disposed at both ends of the central column. The central column drives the two tensioning members to pass through the outer cylinder. Each tensioning member includes an adjusting rod, a pressing block, an elastic element, and several tension blocks. The adjusting rod passes through the pressing block and is screwed to the end of the central column. Each tension block is slidably disposed at the end of the central column and is circumferentially distributed around the outer periphery of the pressing block. The elastic element is sleeved on each tension block and drives each tension block to move closer to the pressing block. The adjusting rod drives the pressing block to push each tension block away from each other, thereby causing each tension block to open up the outer cylinder.
[0009] Optionally, the outer cylinder is made of rolled iron sheets.
[0010] Optionally, the outer cylinder has multiple through holes.
[0011] Optionally, the diameter of the extrusion block gradually decreases towards the center of the central column, so that the outer wall of the extrusion block has an inclined wall structure.
[0012] Optionally, the angle between the outer side wall of the extrusion block and the end face of the extrusion block is 84° to 87°.
[0013] Optionally, the inner wall of the tensioning block is adapted to the outer wall of the extrusion block.
[0014] Optionally, the central column includes a column body and two end blocks, with the two end blocks respectively disposed at both ends of the column body.
[0015] Optionally, a locking seat is provided on the side of the end block away from the column, and the adjusting rod is screwed to the locking seat.
[0016] Optionally, a clearance groove is provided on the outer side wall of the tensioning block, and the elastic element is accommodated in the clearance groove.
[0017] Optionally, the elastic element is a spring.
[0018] Compared with the prior art, the present invention has at least the following advantages:
[0019] By rotating the adjusting rod in the forward direction, when the extrusion block approaches the central column, it compresses the tensioning blocks, causing them to collectively expand the outer cylinder and thus tighten the yarn coil. When the adjusting rod rotates in the reverse direction, moving the extrusion block away from the central column, it stops compressing the tensioning blocks. Under the elastic force of the elastic element, the tensioning blocks contract, and the outer cylinder contracts towards the center, allowing it to be pulled out of the yarn coil. Compared to existing paper tube structures, the detachable winding structure of this application can be reused repeatedly, thus saving a significant amount of cost associated with disposable paper tubes.

[0026] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.
[0027] like Figures 1 to 3 As shown, a detachable winding structure 10 includes an outer cylinder 100 and a tensioning assembly 200. The outer cylinder 100 is a non-closed rolled structure. The tensioning assembly 200 includes a central post 210 and two tensioning members 220, which are respectively disposed at both ends of the central post 210. The central post 210 is used to drive the two tensioning members 220 into the outer cylinder 100. The tensioning member 220 includes an adjusting rod 221, a pressing block 222, an elastic member 223, and several tensioning blocks 224. The adjusting rod 221 passes through... Each tensioning block 224 is slidably disposed at the end of the central column 210 and is located on the extrusion block 222 and screwed to the end of the central column 210. Each tensioning block 224 is circumferentially distributed on the outer periphery of the extrusion block 222. An elastic element 223 is sleeved on each tensioning block 224. The elastic element 223 is used to drive each tensioning block 224 to move closer to the extrusion block 222. An adjusting rod 221 is used to drive the extrusion block 222 to push each tensioning block 224 away from each other, thereby causing each tensioning block 224 to open the outer cylinder 100.
[0028] It should be noted that the outer cylinder 100 is a non-closed rolled structure. In one embodiment, the outer cylinder 100 is made of rolled iron sheet. Specifically, the iron sheet is wound from one end to the other, with the two ends of the iron sheet overlapping each other. In one embodiment, the thickness of the iron sheet is 1mm to 2mm. The outer cylinder 100 is the basis for winding the wire. The central column 210 and the two tensioning members 220 pass through the outer cylinder 100, so that the two tensioning members 220 expand the outer cylinder 100, allowing the outer cylinder 100 to stably support the wire. Further, for any tensioning member 220, the adjusting rod 221 passes through the pressing block 222, and the adjusting rod 221 is screwed to the end of the central column 210. Each tensioning block 224 is slidably mounted on the end of the central column 210, and each tensioning block 224 is distributed around the outer periphery of the pressing block 222. The elastic element 223 is sleeved on the outer wall of each tensioning block 224. Under the elastic force of the elastic element 223, each tensioning block 224 moves towards the central pressing block 222. Thus, by rotating the adjusting rod 221 forward, when the pressing block 222 approaches the central column 210, the pressing block 222 presses against each tensioning block 224, causing the tensioning blocks 224 to collectively expand the outer cylinder 100, thereby allowing the outer cylinder to expand outward and tighten the yarn roll. When the adjusting rod 221 rotates in the reverse direction, causing the pressing block 222 to move away from the central column 210, the pressing block 222 no longer presses against the tensioning blocks 224. Under the elastic force of the elastic element 223, each tensioning block 224 contracts, and the outer cylinder 100 contracts towards the center, allowing it to be pulled out from the yarn roll. Compared to existing paper tube structures, the detachable winding structure 10 of this application can be reused repeatedly, thus saving a significant amount of cost associated with disposable paper tubes.
[0029] In one embodiment, both the tensioning block 224 and the compression block 222 are made of plastic, thus ensuring sufficient friction between the tensioning block 224 and the compression block 222.
[0030] In one embodiment, in one of the tensioning members 220, three tensioning blocks 224 are provided, and the three tensioning blocks 224 are distributed circumferentially at equal angles on the outer periphery of the extrusion block 222.
[0031] like Figure 1 As shown, in one embodiment, the outer cylinder 100 has a plurality of through holes 110. In this way, the friction between the yarn roll and the outer cylinder 100 can be increased through the through holes 110, so that the yarn roll can be stably wound on the outer cylinder 100.
[0032] In one embodiment, the diameter of the extrusion block 222 gradually decreases towards the center of the central column 210, so that the outer wall of the extrusion block 222 has an inclined wall structure.
[0033] It should be noted that the extrusion block 222 has a frustum structure. When the adjusting rod 221 is rotated under force, the extrusion block 222 moves closer to the central column 210, causing the extrusion block 222 to open up each tensioning block 224.
[0034] like Figure 3 As shown, in one embodiment, the included angle D between the outer wall of the extrusion block 222 and the end face of the extrusion block 222 is 84° to 87°.
[0035] It should be noted that the included angle D can also be 85° or 86°. In this way, when the adjusting rod 221 is subjected to force and drives the pressing block 222 to approach the central column 210, the inclined wall surface of the pressing block 222 reliably expands each tensioning block 224.
[0036] like Figure 3 As shown, in one embodiment, the inner wall of the tensioning block 224 is adapted to the outer wall of the compression block 222.
[0037] It should be noted that the inclination direction of the inner wall of the tension block 224 is opposite to the inclination direction of the outer wall of the compression block 222, so that the inner wall of the tension block 224 and the outer wall of the compression block 222 are adapted to each other. Thus, whether the compression block 222 opens each tension block 224 or the elastic element 223 drives each tension block 224 to contract, it ensures that the inner wall of the tension block 224 and the outer wall of the compression block 222 are tightly fitted. This allows the outer wall of the tension block 224 to be tightly fitted to the inner wall of the outer cylinder 100 when the tension block 224 slides at the end of the central column 210, thereby ensuring that the outer cylinder 100 is reliably opened by each tension block 224.
[0038] like Figure 2 and Figure 3 As shown, in one embodiment, the central column 210 includes a column body 211 and two end blocks 212, which are respectively disposed at both ends of the column body 211.
[0039] It should be noted that the two end blocks 212 are welded to the column 211 respectively, and the two end blocks 212 are parallel to each other. Two tensioning members 220 are located on the two end blocks 212 respectively. Specifically, in one of the tensioning members 220, each tensioning block 224 is slidably mounted on the end block 212. For example, the end block 212 has oblong holes distributed along its axial direction. Bolts pass through these oblong holes and are screwed onto the tensioning blocks 224, ensuring that the bolts and tensioning blocks 224 do not clamp the end block 212, allowing the tensioning blocks 224 to slide on the end block 212.
[0040] like Figure 3 As shown, in one embodiment, a locking seat 213 is also provided on the side of the end block 212 away from the column 211, and the adjusting rod 221 is screwed to the locking seat 213.
[0041] It should be noted that the lock seat 213 is welded to the outer surface of the end block 212. The lock seat 213 has an internal threaded hole, and the adjusting rod 221 is screwed into the internal threaded hole.
[0042] like Figure 2 and Figure 3 As shown, in one embodiment, a clearance groove 2241 is provided on the outer side wall of the tensioning block 224, and the elastic element 223 is accommodated in the clearance groove 2241.
[0043] It should be noted that, in order to avoid the elastic element 223 from contacting the inner wall of the outer cylinder 100, a clearance groove 2241 is laterally formed on the outer wall of the tensioning block 224, so that the elastic element 223 is accommodated in the clearance groove 2241. In one embodiment, the elastic element 223 is a spring, and the spring is connected end to end in the clearance groove 2241, so that each tensioning block 224 has a tendency to move closer to each other and contract under the elastic force of the spring.
[0044] like Figure 3 As shown, in one embodiment, the tensioning member 220 further includes a return spring 225, which is sleeved on the outer wall of the adjusting rod 221 and abuts against the pressing block 222 and the locking seat 213 respectively.
[0045] Thus, under the elastic thrust of the return spring 225, the pressing block 222 tends to move away from the lock seat 213 in its natural state. Therefore, when the adjusting rod 221 is removed from the lock seat 213, the pressing block 222 will follow the adjusting rod 221 away from the lock seat 213, thereby making each tensioning block 224 reliably contracted by the elastic element 223.
[0046] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
