Description

Technical Field

[0001] This application relates to the technical field of spools, and particularly to a multi-layer anti-extrusion spool. Background Art

[0002] In the wire and cable production industry, various communication line products have high requirements for structural stability and usually require their structures not to change during use. However, most communication cables are soft in texture and prone to deformation, and this phenomenon is more obvious in wire materials with a foamed structure. After the communication cables are produced, they need to be wound and packaged on spools. However, when the communication cables are wound around the spool in multiple layers, the bottom communication cables are deformed due to extrusion, resulting in quality problems of the products. Utility Model Content

[0003] In order to solve the above technical problems, this application provides a multi-layer anti-extrusion spool, which includes a spool shaft, two side plates arranged on both sides of the spool shaft, and several layers of support components arranged between the two side plates. The support components include several support plates arranged in a ring along the center line of the spool shaft between the side plates, and both ends of the support plates are detachably connected to the side plates.

[0004] Preferably, the side plates are provided with several layer mounting holes, and fixing members connected to the support plates are inserted through the mounting holes.

[0005] Preferably, support steps are arranged on the spool shaft inside the two side plates.

[0006] Preferably, a gap for the cable to pass through is formed between two adjacent support plates.

[0007] Preferably, the height of the support step is 50 - 300 mm.

[0008] As can be seen from the above, the following beneficial effects can be obtained by applying this application: By arranging two side plates on both sides of the spool shaft and several layers of support components between the two side plates, each layer of support component is circularly distributed between the two side plates with different radii. The support components include several support plates arranged in a ring along the center line of the spool shaft between the side plates, and both ends of the support plates are detachably connected to the side plates. First, the cable is wound by the spool shaft, and the appropriate winding length is selected according to the pressure bearing capacity of the cable. Then, one layer of support component is added, and the cable is continued to be wound on the support plate. After winding a certain length, the support component can be continued to be added. Thus, the pressure on the bottom cables is dispersed through multiple layers of support components, avoiding the deformation of the bottom cables due to excessive extrusion pressure and ensuring the quality of the entire spool of cable products.

[0013] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of them. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0014] Embodiment

[0015] To solve the above technical problems, this embodiment provides a multi-layer anti-extrusion spool, as Figure 1-2 shown, which includes a disk shaft 5 and two side plates 1 arranged on both sides of the disk shaft 5. A plurality of layers of support components are arranged between the two side plates 1. Each layer of support components is circularly distributed between the two side plates 1 with different radii. The support component includes a plurality of support plates 2 arranged in a ring along the center line of the disk shaft 5 between the side plates 1. The two ends of the support plate 2 are detachably connected to the side plates 1. First, the cable is wound around the disk shaft 5, and the appropriate winding length is selected according to the pressure-bearing capacity of the cable. Then, an additional layer of support component is added, and the cable is continued to be wound on the support plate 2. After winding a certain length, the support component can be continuously added. Thus, the pressure received by the bottom-layer cable is dispersed through the multi-layer support components, avoiding deformation of the bottom-layer cable due to excessive extrusion pressure and ensuring the quality of the entire axis of cable products.

[0016] Specifically, a plurality of layer mounting holes are formed in the side plates 1, and fixing members 3 connected to the support plates 2 are inserted through the mounting holes. The fixing members 3 are inserted through the mounting holes and connected to the end faces of the support plates 2, and thus the two ends of the support plates 2 are detachably connected to the two side plates 1 through the fixing members 3. The fixing members 3 can be bolts or positioning pins, etc. Additionally, in some other embodiments, the fixing members 3 and a plurality of support plates 2 are arranged in a ring around the disk shaft 5, thereby forming a layer of support assembly, and in this way, multiple layers of support assemblies can be continuously added to disperse the pressure on the bottom-layer cables.

[0017] Furthermore, as Figure 3 shown, support steps 4 are provided on the disk shaft 5 inside the two side plates 1. Support steps 4 are provided below each layer of support assembly, and the support plates 2 of the support assembly abut against the support steps 4, thereby forming a space for accommodating cables between the support plates 2 and the disk shaft 5 and between each support assembly. First, the cables are wound by the disk shaft 5, and then after adding one or more layers of support assemblies, the winding continues.

[0018] In the above solution, a gap for the cables to pass through is formed between two adjacent support plates 2. Furthermore, after adding the support plates 2, the cables can pass through the gap and continue to be wound on this layer of support plates 2.

[0019] To ensure there is sufficient space to accommodate the wound cables, the width of the support step 4 is 1 mm - 20 mm, and the height is 50 - 300 mm. Further, in this embodiment, specific dimensions are provided. The diameter of the side plate 1 is 630 mm, the diameter of the disk shaft 5 is 315 mm, the width of the support step 4 is 5 mm, the height of the support step 4 is 65 mm, and the thickness of the support plate 2 is 10 mm. The high-speed wire cable is wound by the disk shaft 5. After the cable is wound for 550 meters, the number of winding layers is 9 layers; when the first layer of support assembly is installed, the diameter of the first layer of support assembly is 465 mm, and the winding continues on the support assembly. When the total length is 1250 meters and the number of cable layers on the first layer of support plate is approximately 9 layers, the next spool is switched to continue the wire arrangement.

[0020] In summary, in the solution of this application, two side plates are provided on both sides of the disk shaft, and a plurality of layers of support assemblies are provided between the two side plates. Each layer of support assembly is distributed in a circular shape with different radii between the two side plates. The support assembly includes a plurality of support plates arranged in a ring along the center line of the disk shaft between the side plates. The two ends of the support plates are detachably connected to the side plates. First, the cables are wound by the disk shaft. According to the pressure-bearing capacity of the cables, a suitable winding length is selected, and then a layer of support assembly is added, and then the winding continues on the support plate. After winding a certain length, the support assembly can be continuously added. Thus, the pressure on the bottom-layer cables is dispersed through multiple layers of support assemblies, avoiding deformation of the bottom-layer cables due to excessive extrusion pressure and ensuring the quality of the entire axis of cable products.

[0021] The above-described embodiments do not constitute a limitation on the protection scope of the technical solution. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the above embodiments shall be included within the protection scope of the technical solution.
