Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of network cable manufacturing, in particular to a wire stranding device for network cable production. BACKGROUND

[0002] Network cable is a subclass of communication cable, specifically a cable used for transmitting data information. The network cable production stranding device is a component of cable production equipment, and is specially used for the stranding process of network cable cores. In the operation of intelligent power distribution systems and facilities, network cable, as the "nerve plexus" of intelligent power distribution systems, needs to be optimized in performance throughout the selection, construction, and maintenance processes. As a physical carrier for data transmission, the wire stranding device (stranding device) plays a decisive role in the electrical performance, mechanical strength, and signal transmission quality of network cable.

[0003] However, in the actual production and application of the wire stranding device, on the one hand, due to the differences in the properties of the wire itself, the materials (such as copper, copper-clad aluminum), diameters, stranding directions, or hardnesses of different cores, the tensile force bearing capacity is different. For example, thin cores are more prone to breakage due to excessive tension than thick cores, and cores with hard insulation layers may generate additional resistance when unwinding, so there is often a problem of unbalanced tension in the unwinding process. This may result in structural defects such as back stranding and loose stranding, or even breakage due to excessive tension or defects in the wire material, directly affecting the quality of the finished network cable.

[0004] In the prior art, to solve the above problems, an authorized invention of a tension control anti-breakage automatic adjustment control device for a communication cable stranding device (CN108597689B) is disclosed, which has the beneficial effect of "improving the unwinding speed to some extent and improving the production efficiency, and avoiding the problem of reduced cable quality caused by manual splicing by protecting the twisted cores from being broken and strained". However, the comparative document cannot quickly adjust the material and size of the guide wheel according to the actual situation.

[0005] On the other hand, to enhance the wear resistance, waterproofness, corrosion resistance, and structural stability of the cable bundle, and to prevent loosening during stranding, a small amount of thermosetting glue (such as epoxy resin) or hot melt adhesive is applied after stranding, and after curing, an integral structure is formed. In production, the cable bundle often needs to be treated with glue spraying. However, the traditional static spraying method (such as fixed nozzle or brush coating) is limited by factors such as fluctuations in the running speed of the cable bundle and changes in the viscosity of the glue, which can easily cause uneven coating thickness, especially in the gap between the twisted lines.

[0006] In the prior art, in order to solve the above problems, an authorized invention of a full-automatic stranding device and method for composite cable production with publication number CN117524600A is disclosed, which has the beneficial effect of "injecting glue from multiple glue injection holes to coat each cable skin moving to the left, and the three spiral glue scraping pieces of the glue scraping mechanism scrape the glue coated on the outside of the cable, so that the glue can be uniformly coated on the surface of the cable", but the comparative document relies on passive rotation of the cable movement, which easily causes the problem of insufficient coordination between the glue coating direction and the stranding pitch, resulting in gap leakage.

[0007] Therefore, a wire stranding device for network cable production is provided. SUMMARY

[0036] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0037] The embodiments provided by the present application include the following:

[0038] Embodiment one:

[0039] Please refer to Figures 1 to 3 and Figures 6 to 9 As shown in the figure, a wire stranding device for network production includes a plurality of tension adapting assemblies, the tension adapting assemblies are used for stranding a plurality of single wires 13 into a network core wire 14, the plurality of single wires 13 all pass through a wire reel 11, and the network core wire 14 is guided and limited by a stranding frame 12.

[0040] Among them: the wire reel 11 is connected with a driving motor not shown in the figure, the driving motor is used for driving the wire reel 11 to rotate, and the network core wire 14 away from the wire reel 11 is pulled by a traction device not shown in the figure, the traction device is a prior known technology, the traction device is used for pulling the stranded network core wire 14 at a constant speed, and the stranding process is ensured to be stable, in actual use, the driving motor drives the wire reel 11 to rotate, the plurality of single wires 13 on the wire reel 11 are synchronously rotated in the rotating process of the wire reel 11, the stranding action is realized, the plurality of single wires 13 are stranded into the network core wire 14 under the action of the stranding action, and the stranded network core wire 14 is pulled away from the stranding frame 12 by the traction device.

[0041] A plurality of tension adaptation assemblies are arranged in an annular array on the wire disc 11, and the tension adaptation assembly comprises a wire laying groove 21 which is arranged on the wire disc 11, and the wire laying groove 21 is provided with an L-shaped bottom plate 22 on the groove wall close to the side of the center of the wire disc 11, the L-shaped bottom plate 22 is fixedly connected with an electric telescopic rod 23 away from the center of the wire disc 11, the electric telescopic rod 23 comprises a fixed shaft and a telescopic shaft, the telescopic shaft end of the electric telescopic rod 23 is fixedly connected with a micro pressure sensor 24, the micro pressure sensor 24 is fixedly connected with an L-shaped support 25 away from the side of the electric telescopic rod 23, the L-shaped support 25 is clamped with a square plate 26 away from the side of the micro pressure sensor 24, the square plate 26 is fixedly connected with a circular plate 27, the circular plate 27 is fixedly connected with a middle shaft 28 away from the side of the square plate 26, the middle shaft 28 is rotatably connected with a guide wheel 29, and the square plate 26 is fixedly connected with a threaded column 210 away from the side of the circular plate 27.

[0042] As shown in Figure 3 、 Figure 8 , the single wire 13 passes through the inside of the wire laying groove 21, and the single wire 13 is in contact with the guide wheel 29, and the guide wheel 29 plays a role of supporting and guiding the single wire 13.

[0043] It should be noted that, as shown in Figure 1 、 Figure 3 、 Figure 7 , during the plying process of the single wire 13, the end of the single wire 13 close to the stranding frame 12 is in the plying direction, and thus the single wire 13 is subjected to the pressure in the direction of the center of the wire disc 11, and since the guide wheel 29 plays a role of supporting and guiding the single wire 13, i.e. the single wire 13 applies pressure to the guide wheel 29 in the direction of the center of the wire disc 11 during the contact with the guide wheel 29.

[0044] It should be noted that, as shown in Figure 1 、 Figure 3 、 Figure 7 , the micro pressure sensor 24 is located on the side of the guide wheel 29 close to the center of the wire disc 11, and the guide wheel 29 is connected with the micro pressure sensor 24 through the L-shaped support 25, i.e. the pressure applied by the single wire 13 to the guide wheel 29 is transmitted to the L-shaped support 25, and the L-shaped support 25 has an electrical connection relationship between the control system and the electric telescopic rod 23, and the micro pressure sensor 24 is provided with a pressure interval through the control system.

[0045] When the micro pressure sensor 24 detects that the pressure is too large and is not in the normal pressure range, at this time the single wire 13 exerts a large pressure on the guide wheel 29, at this time the single wire 13 tension is out of limit, and then the micro pressure sensor 24 transmits an electrical signal to the control system, the electric telescopic rod 23 is driven by the output shaft of the control system to retract, moving the guide wheel 29 to the center of the wire reel 11, and then the single wire 13 in contact with the guide wheel 29 moves synchronously to the center of the wire reel 11, that is, the tension of the single wire 13 is out of limit, and the single wire 13 is relaxed, that is, the pressure exerted by the single wire 13 on the guide wheel 29 will be reduced compared to when the tension is out of limit, when the micro pressure sensor 24 detects that the pressure is in the normal range, at this time the control system stops the telescopic shaft of the electric telescopic rod 23 from retracting, and the position of the single wire 13 with adjusted tension is stabilized.

[0046] When the micro pressure sensor 24 detects that the pressure is too small and is not in the normal pressure range, at this time the single wire 13 exerts a small pressure on the guide wheel 29, and the single wire 13 is too relaxed, and then the micro pressure sensor 24 transmits an electrical signal to the control system, the electric telescopic rod 23 is driven by the output shaft of the control system to extend, moving the guide wheel 29 away from the center of the wire reel 11, so that the guide wheel 29 moves synchronously with the single wire 13, and the single wire 13 is tightened, when the micro pressure sensor 24 detects that the pressure is in the normal range, at this time the control system stops the telescopic shaft of the electric telescopic rod 23 from extending, and the position of the single wire 13 with adjusted tension is stabilized.

[0047] In summary: in the traditional stranding process, single wire tension imbalance can easily cause structural defects such as back stock and loose stock, and even cause the technical problem of wire breakage due to tension out of limit, through the tension adaptive assembly, the position of the guide wheel 29 can be automatically adjusted according to the real-time tension of the single wire 13, the tension of the single wire 13 is dynamically balanced, and the tension of the single wire 13 is always maintained in the ideal range during the stranding process, avoiding over-tightening and breaking or over-loosening and deforming, precise tension control can reduce defects such as back stock and loose stock, and ensure the consistency of the physical structure of the network cable; at the same time, stable tension helps to optimize the stranding pitch and direction, and improves the electrical performance of the network cable, meeting the requirements of intelligent power distribution system for high-frequency data transmission cable.

[0048] Wherein: refer to Figures 7 to 9As shown, the L-shaped support 25 is divided into a vertical surface and a horizontal surface, a square groove is formed on the vertical surface of the L-shaped support 25, and the square groove of the L-shaped support 25 is adaptively connected with the square plate 26. The square plate 26, the circular plate 27, the middle shaft 28, and the threaded column 210 form a special-shaped shaft. The threaded column 210 is detachably connected with the L-shaped support 25 through a nut. In actual use, the circular plate 27 and the nut are respectively abutted on both sides of the vertical surface of the L-shaped support 25, and the axial direction of the special-shaped shaft is limited through fastening of the nut, so as to ensure that the special-shaped shaft will not affect the axial direction stability of the special-shaped shaft when the guide wheel 29 is driven to rotate by the single-wire 13. At the same time, the square groove of the L-shaped support 25 and the square shape of the square plate 26 can prevent the rotation of the guide wheel 29 from affecting the tightening state of the nut of the special-shaped shaft, and ensure that the radial direction of the special-shaped shaft is limited.

[0049] In the prior art, the material and diameter of the single-wire 13 can change, and the guide wheel 29 supporting and guiding the single-wire 13 needs to be replaced according to the change of the single-wire 13. When the guide wheel 29 needs to be replaced, the user unscrews the nut and removes the nut on the threaded column 210, removes the guide wheel 29 together with the special-shaped shaft from the L-shaped support 25, then installs the guide wheel 29 with corresponding material and size on the L-shaped support 25, and tightens the nut to ensure the stability of the guide wheel 29 and the special-shaped shaft, so as to realize quick replacement of the guide wheel 29.

[0050] In summary, through quick replacement of the guide wheel 29, different single-wire 13 characteristics can be quickly matched. For single-wire 13 with large hardness difference such as copper core, aluminum core and optical fiber, the guide wheel 29 with different surface roughness can be quickly replaced to avoid problems such as surface scratching and plating falling off of the single-wire 13 due to mismatch of materials, and to ensure the electrical performance of the cable wire.

[0051] At the same time, when some guide wheels 29 on the wire disc 11 abnormally wear or jam, the detachable design allows individual replacement of faulty parts, avoids safety accidents such as whole line shutdown or wire breakage caused by local problems, ensures production continuity, and improves production efficiency of multi-category cable network.

[0052] It needs to be added that: a plurality of wire grooves 21 are uniformly arranged on the disc 11, but not every wire groove 21 is provided with an L-shaped bottom plate 22 inside, which serves as: due to the fluctuation of the number of stranded wire produced by the network line, the user can adjust the number of single-stranded wire 13 according to the needs, use the corresponding number and position of the wire groove 21, and install the L-shaped bottom plate 22 inside the corresponding position of the wire groove 21 through bolts, which can realize the correspondence between the actual situation of the tension adaptation assembly and the number of stranded single-stranded wire 13, avoid the waste caused by setting multiple tension adaptation assemblies when the number of stranded single-stranded wire 13 is small, and can make the position and use of the tension adaptation assembly freely controlled by the user, improve the overall use and universality of the tension adaptation assembly.

[0053] In summary, compared with the prior art, the tension adaptation assembly can realize self-adaptive adjustment of the tension of the single-stranded wire 13, and the guide wheel 29 of the corresponding material according to the actual use can be quickly changed, the position and use of the tension adaptation assembly can be freely controlled by the user, and the overall use and universality of the tension adaptation assembly are improved.

[0054] Embodiment two:

[0055] Referring to Figure 1 , Figure 2 and Figure 4 , Figure 5 , the stranding frame 12 is provided with a glue coating and rolling assembly, the glue coating and rolling assembly comprises a support plate 31, the support plate 31 is fixedly connected to one side of the stranding frame 12 away from the disc 11, and the top end of the side of the support plate 31 away from the stranding frame 12 is fixedly connected with a ring-shaped shell 32. The inner wall of the ring-shaped shell 32 is symmetrically rotatably connected with two side plates 33, the top of the ring-shaped shell 32 is fixedly connected with a liquid pipe 34, the outer surface of the side plate 33 close to the stranding frame 12 is fixedly connected with a synchronous hollow ring 35, one side of the stranding frame 12 close to the ring-shaped shell 32 is fixedly connected with a servo motor 36, the servo motor 36 is divided into a fixed end and an output shaft, and the output shaft of the servo motor 36 and the synchronous hollow ring 35 are connected through a synchronous belt 37. The side of the two side plates 33 close to each other is fixedly connected with a middle pipe 38, and the inner surface of the middle pipe 38 is fixedly connected with a rubber ring 39.

[0056] Among them: the top of the liquid pipe 34 is connected with a glue delivery device, and can also be connected with a suction pump.

[0057] Among them: referring to Figure 5 , a plurality of liquid leakage holes are formed in the middle pipe 38 and the rubber ring 39, the ring-shaped shell 32, the two side plates 33, the middle pipe 38, the rubber ring 39 and the synchronous hollow ring 35 are all sleeved on the network core wire 14, and the network core wire 14 is located at the center position of the ring-shaped shell 32, the two side plates 33, the middle pipe 38, the rubber ring 39 and the synchronous hollow ring 35.

[0058] wherein: referring to Figure 5 As shown in the figure, the rubber material of the rubber ring 39 has the property of deformation, so that the rubber ring 39 can be in close contact with the core wire 14 of the network, the purpose is to make the rubber rolling assembly can adapt to different diameter of the core wire 14 of the network, the servo motor 36 is electrically connected with the external remote controller.

[0059] It should be noted that the output shaft rotation direction of the servo motor 36 is consistent with the rotation direction of the wire reel 11, that is, the output shaft rotation direction of the servo motor 36 is the direction of the core wire 14 of the network.

[0060] It should be noted that referring to Figure 5 As shown in the figure, the two side plates 33, the middle tube 38 and the annular shell 32 together constitute a hollow cavity, which is communicated with the outside through the liquid leakage hole formed on the middle tube 38 and the rubber ring 39.

[0061] When the rubber rolling assembly is used, the end of the core wire 14 of the network away from the wire reel 11 is pulled by the traction device to the side away from the wire reel 11, that is, at this time the core wire 14 of the network passes through the inside of the annular shell 32, the two side plates 33, the middle tube 38, the rubber ring 39 and the synchronous hollow ring 35 to the side away from the wire reel 11, and the core wire 14 of the network extrudes the rubber ring 39, so that the rubber ring 39 produces elastic deformation.

[0062] At this time, the user starts the external glue conveying device and the servo motor 36 through the remote controller, with the start of the external glue conveying device, the glue in the external glue conveying device can flow into the cavity composed of the two side plates 33, the middle tube 38 and the annular shell 32 through the liquid pipe 34, and the glue gradually fills in the cavity, and the glue is coated on the core wire 14 of the network through the liquid leakage hole formed on the middle tube 38 and the rubber ring 39.

[0063] And with the start of the servo motor 36, the output shaft of the servo motor 36 drives the synchronous hollow ring 35 to rotate synchronously through the synchronous belt 37, the synchronous hollow ring 35 drives the adjacent side plate 33 to rotate synchronously, and the two side plates 33 are connected through the middle tube 38, and then the two side plates 33, the middle tube 38 and the rubber ring 39 rotate synchronously, and the rotation direction of the two side plates 33, the middle tube 38 and the rubber ring 39 is the direction of the core wire 14 of the network, that is, when the rubber ring 39 is in close contact with the core wire 14 of the network, the rubber ring 39 rotates along the distribution direction of the multiple single wires 13 on the core wire 14 of the network.

[0064] In summary, with the operation of the rubber rolling assembly, the middle tube 38 can rotate around the core wire 14 of the network as the rotation axis, and in the process of rotation, the glue is coated on the core wire 14 of the network, and at the same time the rubber ring 39 rotates along the distribution direction of the multiple single wires 13 on the core wire 14 of the network.

[0065] In summary, by rotating the glue coating and rolling assembly along the distribution direction of the plurality of single wires 13 on the core wire 14 of the mesh wire and coating glue, the coated glue is filled into the gap of the stranded mesh wire 14 along the spiral direction of the stranded structure, avoiding the "blind area" of the static spraying in the prior art. Meanwhile, the middle tube 38 can uniformly cover the core wire 14 of the mesh wire in 360 degrees when rotating, avoiding the uneven thickness caused by the traditional one-sided spraying in the prior art, and the glue overflow and dripping caused by excessive one-sided spraying.

[0066] Meanwhile, by rotating and abutting the rubber ring 39 along the distribution direction of the plurality of single wires 13 on the core wire 14 of the mesh wire, the rubber ring 39 is filled into the gap of the stranded mesh wire 14 along the stranded spiral direction, and the glue is "rubbed and pressed" into the spiral gap of the multi-layer stranded wire. After the core wire 14 of the mesh wire passes through the rubber ring 39, the excess glue on the surface of the core wire 14 of the mesh wire can be scraped off, avoiding excess glue on the surface of the stranded mesh wire 14.

[0067] In addition, when the device is not in use, the excess glue in the cavity formed by the liquid tube 34 and the two side plates 33, the middle tube 38 and the annular shell 32 can be pumped out and discharged by connecting a suction pump to the liquid tube 34.

[0068] In summary, compared with the prior art, the glue coating and rolling assembly can actively rotate and coat glue, and the rotation direction is consistent with the stranded direction, ensuring that the glue is filled into the gap along the thread direction.
