Abstract
Description
Technical Field
[0001] This application belongs to the field of dynamic cable technology, and more specifically, relates to a wrapping tape and wrapping process for a dynamic cable. Background Technology
[0002] Floating platforms at sea require electrical and optical signals to be transmitted via cables and fiber optic cables. Because these platforms move horizontally and vertically on the sea surface due to the influence of waves, this movement causes the cables to move as well. Using traditional cables laid on the seabed would increase the risk of cable damage at the points of contact with the mud. Therefore, floating platforms at sea need to employ dynamic cables to transmit electrical and optical energy.
[0003] Dynamic cables are cables that need to withstand bending, tension, and torsion over long periods. Therefore, dynamic stability must be considered during the design process. Typically, flexible wrapping tape is used to spirally wrap around the cable core and reinforcing elements to make the cable structure compact. However, under long-term bending, tension, and torsion, conventional wrapping tape may loosen or even break at the overlaps, causing the reinforcing elements to detach from the loose or damaged areas and thus lose their reinforcing function. Summary of the Invention
[0004] In view of the above-mentioned defects or improvement needs of the existing technology, this application provides a dynamic cable wrapping tape and wrapping process, which aims to solve the technical problem that the wrapping tape of the current dynamic cable becomes loose and damaged during long-term dynamic process.
[0005] To achieve the above objectives, in a first aspect, this application provides a wrapping tape for a dynamic cable, the wrapping tape including a wrapping tape body and a connecting layer located on the surface of the wrapping tape body, wherein when the wrapping tape body is wrapped around the cable core, the connecting layer is used to connect and fix the overlapping portions of the wrapping tape bodies.
[0006] Preferably, the connecting layer includes a rough surface and a hook surface; the rough surface is located on the outer or inner surface of the wrapping tape body, and the hook surface is located on the other surface of the wrapping tape body; the hook surface is densely covered with hooks, and the rough surface is densely covered with curly fluff; when the wrapping tape body is wrapped around the cable core, the hook surface and the rough surface at the overlap overlap each other, and the hooks on the hook surface and the curly fluff on the rough surface lock together.
[0007] Preferably, the connecting layer is a hot melt adhesive.
[0008] Preferably, the connecting layer is a photocurable adhesive.
[0009] Preferably, the connecting layer is located on the outer surface of the wrapping tape body.
[0010] Preferably, the connecting layer is located at the overlap when the wrapping tape body is wrapped around the cable core, and the width of the connecting layer is the same as the width of the overlapping portion at the overlap.
[0011] Preferably, the wrapping tape body has staggered axial reinforcing ribs and cable-directed reinforcing ribs; the direction of the axial reinforcing ribs is parallel to the axis of the wrapping tape body, and the direction of the cable-directed reinforcing ribs is parallel to the axis of the cable core.
[0012] Preferably, the wrapping tape body is made of non-woven fabric.
[0013] Secondly, this application provides a wrapping process for a dynamic cable, specifically including the following steps:
[0014] A layer of hot melt adhesive is applied to the outer surface of the wrapping tape body;
[0015] The wrapped tape body is heated so that the hot melt adhesive at the overlap melts and bonds the overlapping parts of the wrapped tape body together.
[0016] Thirdly, this application provides a wrapping process for a dynamic cable, specifically including the following steps:
[0017] A layer of UV-curable adhesive is coated on the outer surface of the wrapping tape body;
[0018] The wrapped tape is then exposed to light, which cures the UV-cured adhesive at the overlap, bonding and fixing the overlapping parts of the wrapping tape together.
[0019] Overall, the technical solutions conceived in this application have the following beneficial effects compared with the prior art:
[0020] (1) This application adds a connecting layer with adhesive function to the surface of the wrapping tape body. During the process of wrapping the dynamic cable with the wrapping tape, the connecting layer will connect and fix the overlapping part of the wrapping overlap, thereby strengthening the wrapping tape of the dynamic cable, so that the wrapping tape is not easy to loosen, break and fall off during long-term dynamic process.
[0021] (2) The connection layer of this application uses a nylon buckle structure to bond and fix the overlapping part of the wrapping. The density, material and size of the nylon buckle structure can be adjusted to flexibly obtain the required bonding force. Moreover, the use of this structure does not require modification of the existing wrapping process and has strong adaptability to existing equipment.
[0022] (3) The bonding layer of this application uses hot melt adhesive or light-curing adhesive to bond and fix the overlapping parts of the wrapping. The above two materials are easy to obtain, have good bonding effect, and the wrapping process based on the above materials is simple and easy to implement.
[0023] (4) The wrapping tape body of this application is made of non-woven fabric. Hot melt adhesive and UV-cured adhesive can easily penetrate and fuse into the non-woven fabric in the molten state. In this way, the overlapping parts of the non-woven fabric can be more firmly bonded together after the hot melt adhesive and UV-cured adhesive have solidified. Similarly, nylon buckles are also easier to process onto the non-woven fabric wrapping tape body.
[0024] (5) The wrapping tape body of this application is provided with reinforcing ribs in a staggered manner in a specified direction. The arrangement direction of the reinforcing ribs is consistent with the force direction of the wrapping tape during dynamic process, which further increases the stability of the wrapping tape and improves the stability and lifespan of dynamic performance.

Detailed Implementation
[0032] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0033] This application proposes a wrapping tape for a dynamic cable, comprising a wrapping tape body and a connecting layer with adhesive function located on the surface of the wrapping tape body. After the wrapping tape body is wrapped around the cable core of the dynamic cable, the connecting layer connects and fixes the overlapping portions of the wrapping tape body. This increases the stability of the wrapping tape under long-term dynamic conditions. The technical solution of this application will be described in detail below through several embodiments.
[0034] Example 1:
[0035] like Figure 1 The image shown is a side view of a wrapping tape proposed in this application. It can be seen that the wrapping tape includes a wrapping tape body 1 and a connecting layer 2 located on the surface of the wrapping tape body 1. The connecting layer 2 uniformly covers the outer surface of the wrapping tape body 1. The material of the connecting layer 2 is hot melt adhesive or UV-cured adhesive, or other cured adhesives with good bonding properties that are waterproof and corrosion-resistant.
[0036] In this embodiment, the hot melt adhesive can be selected from ethylene-vinyl acetate copolymer, polyamide, polyester, polyethylene, polypropylene, polyvinyl chloride, or polyurethane, etc. It is essential to ensure that the melting point of the selected hot melt adhesive is lower than the melting point of the materials contained in the cable.
[0037] UV-curable adhesives can be made of epoxy resins, acrylates, unsaturated polyesters, polyurethane acrylates, polysiloxane acrylates, or acrylate-polyurethane mixtures, etc.
[0038] like Figure 5 As shown, after the wrapping tape body 1 wraps around the cable core 3, the wrapping tape body 1 will form an overlapping part at the overlap 4. At the overlapping part, the connecting layer 2 located on the outer surface of the wrapping tape body 1 and the inner surface of the wrapping tape body 1 come into contact. Through the adhesive ability of the connecting layer 2, the outer surface and the inner surface of the overlapping part of the wrapping tape body 1 are bonded and fixed, thereby ensuring that the wrapping tape is not easy to loosen, break or fall off during long-term dynamic processes.
[0039] As those skilled in the art will know, the connecting layer covering the inner surface of the wrapping tape can also bond and fix the overlapping parts of the wrapping tape after the wrapping tape wraps around the cable core.
[0040] Example 2:
[0041] like Figure 2 The image shown is a top view of a wrapping tape according to this application. It includes a wrapping tape body 1 and a connecting layer 2 located on the surface of the wrapping tape body 1. Figure 2 As can be seen, the connecting layer 2 covers part of the outer surface of the wrapping tape body 1. This part of the outer surface is the overlapping part of the wrapping tape body 1 at the overlap after wrapping the cable core. The width of this part of the outer surface is the same as the width of the overlapping part of the wrapping tape body 1.
[0042] Since only the overlapping part of the wrapping tape body 1 needs to be fixed, the bonding layer 2 with adhesive capability only needs to cover part of the outer surface of the wrapping tape body 1 to achieve the wrapping reinforcement function.
[0043] In this embodiment, the material of the bonding layer is hot melt adhesive or light-curing adhesive, or other curing adhesives with good adhesion, waterproof and corrosion resistant properties.
[0044] like Figure 5 As shown in this embodiment, after the wrapping tape wraps around the cable core 3, the wrapping tape body 1 will form an overlapping part at the overlap 4. At the overlapping part, the connecting layer 2 located on the outer surface of the wrapping tape body 1 and the inner surface of the wrapping tape body 1 are in contact. Through the adhesive ability of the connecting layer 2, the outer surface and the inner surface of the overlapping part of the wrapping tape body 1 are connected and fixed, thereby strengthening the wrapping tape of the dynamic cable, so that the wrapping tape is not easy to loosen, break and fall off during long-term dynamic process.
[0045] As those skilled in the art will know, the connecting layer covering the inner surface of the wrapping tape body 1 can also connect and fix the overlapping parts of the wrapping tape after wrapping the cable core.
[0046] Example 3:
[0047] like Figure 3 The image shown is a side view of a wrapping tape according to this application. The wrapping tape includes a wrapping tape body 1 and a connecting layer 2. The connecting layer 2 includes a rough surface 2a and a hook surface 2b. The rough surface 2a is located on the outer surface of the wrapping tape body 1, and the hook surface 2b is located on the inner surface of the wrapping tape body 1. Of course, the bonding ability of the connecting layer 2 is not affected even if the positions of the rough surface 2a and the hook surface 2b are interchanged.
[0048] The hook side 2b is densely covered with hooks, and the nap side 2a is densely covered with curly nap; the size, density, and material of the hooks and nap can be flexibly adjusted according to the required bonding ability.
[0049] When the wrapping tape body 1 wraps around the cable core 3, the rough surface 2a and hook surface 2b of the overlap 4 overlap each other, and the curled fibers on the rough surface 2a and the hooks on the hook surface 2b lock together. This strengthens the wrapping tape of the dynamic cable, making it less likely to loosen, break, or fall off during long-term dynamic operation.
[0050] Example 4:
[0051] like Figure 4 The image shown is a perspective view of a wrapping tape provided in an embodiment of this application. In this embodiment, the wrapping tape body 1 is made of non-woven fabric. Hot melt adhesive and UV-curable adhesive easily penetrate and fuse into the non-woven fabric in their molten state. This allows the overlapping portions of the non-woven fabric to bond more firmly after the hot melt adhesive and UV-curable adhesive have solidified. Similarly, nylon fasteners are also easier to process onto the non-woven fabric wrapping tape.
[0052] The wrapping tape body 1 has staggered axial reinforcing ribs and cable-oriented reinforcing ribs; the direction of the axial reinforcing ribs is parallel to the axis of the wrapping tape body 1, and the direction of the cable-oriented reinforcing ribs is parallel to the axis of the cable core. The arrangement direction of the reinforcing ribs is consistent with the direction of force on the wrapping tape during dynamic processes, thereby reducing the dynamic amplitude of the wrapping tape and further increasing the stability of the wrapping tape.
[0053] Example 5:
[0054] like Figure 5 The image shows a wrapping tape proposed in this application. The connecting layer 2 includes both a rough surface 2a and a hook surface 2b, as well as an adhesive layer 2c made of hot melt adhesive or UV-curable adhesive.
[0055] As shown in the figure, the adhesive layer 2c and the rough surface 2a cover part of the outer surface of the wrapping tape body 1. This part of the outer surface is the overlapping part of the wrapping tape body 1 at the overlap after wrapping the cable core. The width of this part of the outer surface is the same as the width of the overlapping part of the wrapping tape.
[0056] The hook face 2b is located on a portion of the inner surface of the wrapping tape body 1. This portion of the inner surface and the nap face are symmetrical about the wrapping tape. At the same time, the width of the hook face 2b and the nap face 2a are the same. In this way, after wrapping, the hook face 2b and the nap face 2a can completely overlap each other, and the hook of the hook face 2b and the curled nap face 2a lock together.
[0057] At the same time, after wrapping, in the overlapping part, the adhesive layer 2c on the outer surface and the inner surface of the wrapping tape body 1 come into contact. Through the adhesive ability of the adhesive layer 2c, the outer surface and the inner surface of the overlapping part of the wrapping tape body 1 are connected and fixed, thereby strengthening the wrapping tape of the dynamic cable, so that the wrapping tape is not easy to loosen, break and fall off during long-term dynamic process.
[0058] As those skilled in the art will know, swapping the positions of the rough and hook sides does not affect the bonding ability. The adhesive layer covering the inner surface of the wrapping tape body 1 can also connect and fix the overlapping parts of the wrapping tape after wrapping the cable core.
[0059] In this embodiment, adhesive bonding and nylon fastening are used in combination, which can give full play to the advantages of the two connection and fixation technologies during the wrapping process.
[0060] Example 6:
[0061] like Figure 6 The image shows a wrapping process for a wrapping tape according to an embodiment of this application:
[0062] First, a layer of hot melt adhesive is coated on the outer surface of the wrapping tape body 1; the melting point of the hot melt adhesive is lower than the melting point of the material contained in the cable.
[0063] Then, the cable core 3 is wrapped with the wrapping tape body 1. After wrapping, a far-infrared heating device is added to the production line to heat the wrapped wrapping tape body 1, so that the hot melt adhesive at the overlapping part of the overlap 4 melts and firmly bonds and fixes the overlapping part of the wrapping tape body together.
[0064] Example 7:
[0065] This embodiment proposes another wrapping process:
[0066] First, during the wrapping process, a glue injection head linked with the wrapping head is used to spray a light-curing resin onto the outer surface of the overlap 4 of the wrapping tape body before wrapping.
[0067] A UV curing unit is added at the rear end of the wrapping production line to irradiate the overlapping parts of the wrapping tape body with ultraviolet light, so that the UV-cured resin cures and firmly bonds and fixes the overlapping parts of the wrapping tape body together.
[0068] Comparative experiments demonstrate:
[0069] Experiment 1: A dynamic test was conducted on the dynamic cable obtained by wrapping the cable according to the present application. The dynamic cable was dynamically moved by a dynamic wheel and subjected to 10,000 fatigue tests. The breakage of the wrapping tape was observed and recorded.
[0070] Experiment 2: A dynamic test was conducted on the dynamic cable obtained by the conventional wrapping method. The dynamic cable was dynamically moved by a dynamic wheel and subjected to 10,000 fatigue tests. The breakage of the wrapping tape was observed and recorded.
[0071] Comparing the recorded results of Test 1 and Test 2, it can be seen that the wrapping tape of this application is more intact and undamaged than the conventional method. It is more suitable for long-term dynamic environments.
