Description

Technical Field

[0001] The invention relates to the technical field of network cable manufacturing, in particular to a wire stranding device used for network cable production. Background Art

[0002] Network cables are a subcategory of communications cables, specifically cables used for transmitting data. Network cable stranding devices are a component of cable production equipment, specifically used for twisting network cable cores. In the operation of intelligent power distribution systems and facilities, network cables serve as the "nerves" of intelligent power distribution systems, and their performance optimization must be integrated throughout the entire process from selection to construction and maintenance. Furthermore, as the physical carrier of data transmission, the stranding device (twisting device) is a core piece of production equipment in the cable manufacturing process. Its operating precision and craftsmanship play a decisive role in the electrical performance, mechanical strength, and signal transmission quality of the network cables.

[0003] However, in the actual production application of wire stranding devices, due to differences in the inherent characteristics of the wires, different wire core materials (such as copper, copper-clad aluminum), diameters, twist directions, and insulation hardness may vary, resulting in different tensile stress tolerances. For example, thinner wire cores are more susceptible to breakage due to excessive tension than thicker wire cores, while wire cores with harder insulation may create additional resistance during payout. As a result, unbalanced single-wire tension often occurs during the payout process. This can lead to structural defects such as back strands and loose strands at the very least, and even breakage due to excessive tension or material defects, directly affecting the qualified rate of the finished network cable.

[0004] In the prior art, in response to the above problems, there is an authorized invention, such as the publication number CN108597689B, which describes a tension control and anti-breakage automatic adjustment control device for communication cable cabling equipment. It records the beneficial effects of "increasing the pay-off speed to a certain extent, improving production efficiency, and protecting the twisted wire core from breakage and strain, thereby avoiding the problem of cable quality degradation caused by manual splicing." However, the comparative document cannot quickly adjust the material and size of the guide wheel according to actual conditions.

[0005] On the other hand, to enhance the wear resistance, waterproofness, corrosion resistance, and structural stability of cable harnesses, and to prevent loosening when plying multiple cores, a small amount of thermosetting glue (such as epoxy resin) or hot melt adhesive is applied after twisting to form an integrated structure after curing. However, traditional static spraying methods (such as fixed nozzles or brush coating) are limited by factors such as fluctuations in the running speed of the harness and changes in glue viscosity, which can easily lead to uneven coating thickness. This is especially prominent in the gaps between the strands of multi-stranded wire, where coating leaks are particularly prominent.

[0006] In the prior art, in response to the above problems, there is an authorized invention with publication number: CN117524600A, which records the beneficial effect of "injecting glue from multiple injection holes, thereby coating the surface of each cable moving to the left, and the three spiral scrapers in the scraping mechanism scrape the glue coated on the outside of the cable, so that the glue can be evenly coated on the surface of the cable." However, the comparative document relies on the passive rotation of the cable movement, which easily causes insufficient coordination between the glue coating direction and the twisted wire pitch, resulting in gap leakage.

[0007] To this end, a wire stranding device for network cable production is proposed. Summary of the Invention

[0008] The object of the present invention is to provide a wire stranding device for network cable production to solve the problems raised in the above background technology.

[0009] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a wire stranding device for network cable production, comprising multiple tension-adaptive components, the tension-adaptive components being used to twist multiple single-strand wires into a network cable core wire, the multiple single-strand wires all passing through the cable drum, the network cable core wire is guided and limited by the twisting frame, and the multiple tension-adaptive components are arranged in a circular array on the cable drum, the tension-adaptive components comprising a wire-releasing groove, the wire-releasing groove is opened on the cable drum, an L-shaped bottom plate is provided on the groove wall on the side of the wire-releasing groove close to the center position of the cable drum, an electric telescopic rod is fixedly connected to the side of the L-shaped bottom plate away from the center of the cable drum, the electric telescopic rod comprises a fixed shaft and a telescopic shaft, the telescopic shaft end of the electric telescopic rod is fixedly connected to a micro pressure sensor, the micro pressure sensor is fixedly connected to an L-shaped bracket on the side away from the electric telescopic rod, a square plate is clamped on the side of the L-shaped bracket away from the micro pressure sensor, a circular plate is fixedly connected to the square plate, the circular plate is fixedly connected to the central axis on the side away from the square plate, a guide wheel is rotatably connected to the central axis, and a threaded column is fixedly connected to the side of the square plate away from the circular plate.

[0010] Furthermore, a glue coating and rolling assembly is provided on the stranding frame, and the glue coating and rolling assembly includes a support plate, which is fixedly connected to the side of the stranding frame away from the wire drum, and the top of the support plate on the side away from the stranding frame is fixedly connected to an annular shell, and the inner wall of the annular shell is symmetrically connected to two side plates, and the top of the annular shell is fixedly connected to a liquid pipe, and the outer surface of the side plate close to the stranding frame is fixedly connected to a synchronous hollow ring, and the side of the stranding frame close to the annular shell is fixedly connected to a servo motor, and the servo motor is divided into a fixed end and an output shaft, and the output shaft of the servo motor and the synchronous hollow ring are connected by a synchronous belt through a synchronous wheel transmission, and the side of the two side plates close to each other is fixedly connected to a middle tube, and the inner surface of the middle tube is fixedly connected to a rubber ring.

[0011] Furthermore, the L-shaped bracket is divided into a vertical surface and a horizontal surface, and a square groove is provided on the vertical surface of the L-shaped bracket.

[0012] Furthermore, the single strand of wire conflicts with the guide wheel, the square groove of the L-shaped bracket is snap-fitted with the square plate, and the threaded column is detachably connected to the L-shaped bracket through a nut.

[0013] Furthermore, multiple leakage holes are provided on the middle tube and the rubber ring. The annular shell, two side plates, middle tube, rubber ring and synchronous hollow ring are all sleeved on the network cable core wire, and the network cable core wire is located at the center of the annular shell, two side plates, middle tube, rubber ring and synchronous hollow ring.

[0014] Furthermore, the servo motor is electrically connected to the external remote control, and the rotation direction of the output shaft of the servo motor is consistent with the rotation direction of the cable drum, that is, the rotation direction of the output shaft of the servo motor is the plying direction of the core wires of the network cable.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The tension adaptation component automatically adjusts the guide wheel position based on the real-time tension of the individual strands, dynamically balancing the tension of the individual strands to ensure that the strand tension remains within the ideal range during twisting, preventing breakage due to excessive tension or deformation due to excessive looseness. Precise tension control reduces defects such as back strands and loose strands, ensuring the consistency of the cable's physical structure. Furthermore, stable tension helps optimize the twist pitch and direction, improving the cable's electrical performance and meeting the requirements of intelligent power distribution systems for high-frequency data transmission cables. By quickly replacing the guide wheel, the characteristics of different single-strand cables can be quickly matched. For single-strand cables with large differences in hardness, such as copper core, aluminum core, and optical fiber, guide wheels with different surface roughness can be quickly replaced to avoid problems such as single-strand cable surface scratches and coating shedding caused by material mismatch, thereby ensuring the electrical performance of the cable. At the same time, if a guide wheel on the cable drum is abnormally worn or stuck, the detachable design allows for individual replacement of the faulty component, avoiding safety accidents such as full line shutdown or cable breakage caused by local problems, ensuring production continuity and improving the production efficiency of multiple types of cables and network cables. Compared with existing technologies, the tension adaptation component can realize adaptive adjustment of the tension of a single strand, and quickly and more quickly adapt the guide wheel to the material and size according to actual usage. It can also realize the position and number of tension adaptation components to be freely controlled by the user, thus improving the comprehensiveness and versatility of the tension adaptation component. The glue coating and rolling assembly rotates and applies glue along the distribution direction of multiple single strands on the core of the network cable, so that the applied glue is filled into the gaps of the core wires of the network cable after being twisted along the spiral direction of the twisted structure, avoiding the "blind area" of static spraying in the existing technology. At the same time, when the middle tube rotates, it can achieve 360-degree uniform coverage of the core wire of the network cable, avoiding the uneven thickness caused by traditional one-sided spraying and the overflow and dripping of glue caused by excessive one-sided spraying in the technology. At the same time, the rubber ring rotates and resists along the distribution direction of multiple single-strand wires on the network cable core wire, and the rubber ring fills into the gap between the strands of the network cable core wire along the twisted spiral direction, "kneading" the glue into the spiral gap between the multi-layer twisted wires, and after the network cable core wire passes through the rubber ring, the excess glue on the surface of the network cable core wire can be scraped off to avoid excess glue on the surface after the network cable core wire is twisted; In summary, compared with the existing technology, the glue coating and rolling assembly can realize active rotary gluing and the rotation direction is consistent with the direction of the twisted wire, ensuring that the glue fills the gap along the thread direction.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0019] The present invention provides the following embodiments: Example 1: See also Figures 1 to 3 and Figures 6 to 9 As shown, a wire stranding device for network cable production includes multiple tension adaptation components, which are used to twist multiple single-strand wires 13 into a network cable core wire 14. The multiple single-strand wires 13 all pass through the wire drum 11, and the network cable core wire 14 is guided and limited by the twisting frame 12.

[0020] Among them: the wire drum 11 is externally connected to a driving motor not shown in the figure, and the driving motor is used to drive the wire drum 11 to rotate, and the network cable core wire 14 is pulled by a traction device not shown in the figure on the side away from the wire drum 11. The traction device is an existing known technology. The traction device is used to pull the twisted network cable core wire 14 at a constant speed to ensure that the twisting process is stable. In actual use, the driving motor drives the wire drum 11 to rotate, and the rotation of the wire drum 11 drives the multiple single-strand wires 13 thereon to rotate synchronously to realize the twisting action, so that the multiple single-strand wires 13 are twisted into the network cable core wire 14 in the single-strand wire 13 under the action of the twisting action, and the twisted network cable core wire 14 is pulled away from the twisting frame 12 by the traction device.

[0021] Multiple tension adaptation components are arranged in a circular array on the wire drum 11, and the tension adaptation components include a wire pay-off groove 21, which is opened on the wire drum 11, and an L-shaped bottom plate 22 is provided on the groove wall of the wire pay-off groove 21 on the side close to the center of the wire drum 11. The side of the L-shaped bottom plate 22 away from the center of the wire drum 11 is fixedly connected to an electric telescopic rod 23, and the electric telescopic rod 23 includes a fixed axis and a telescopic axis. The telescopic axis end of the electric telescopic rod 23 is fixedly connected to a micro pressure sensor 24, and the side of the micro pressure sensor 24 away from the electric telescopic rod 23 is fixedly connected to an L-shaped bracket 25. The side of the L-shaped bracket 25 away from the micro pressure sensor 24 is clamped with a square plate 26, and a circular plate 27 is fixedly connected to the square plate 26. The side of the circular plate 27 away from the square plate 26 is fixedly connected to the central axis 28, and a guide wheel 29 is rotatably connected to the central axis 28. The side of the square plate 26 away from the circular plate 27 is fixedly connected to a threaded column 210.

[0022] Among them: reference Figure 3 、 Figure 8 As shown, the single-strand wire 13 passes through the wire-releasing groove 21 , and the single-strand wire 13 contacts the guide wheel 29 , which supports and guides the single-strand wire 13 .

[0023] Please note: Refer to Figure 1 、 Figure 3 、 Figure 7 As shown, during the stranding process of the single-strand wire 13, since the end of the single-strand wire 13 close to the stranding frame 12 is in the stranding direction, the single-strand wire 13 is exerted with pressure toward the center of the wire drum 11. Since the guide wheel 29 supports and guides the single-strand wire 13, that is, during the process of the single-strand wire 13 contacting the guide wheel 29, pressure is exerted on the guide wheel 29 toward the center of the wire drum 11.

[0024] It should be added that: Figure 1 、 Figure 3 、 Figure 7 As shown, the micro pressure sensor 24 is located on the side of the guide wheel 29 close to the center of the wire drum 11, and the guide wheel 29 is connected to the micro pressure sensor 24 through the L-shaped bracket 25, that is, the pressure applied to the guide wheel 29 by the single strand of wire 13 will be transmitted to the L-shaped bracket 25, and there is an electrical connection between the L-shaped bracket 25 and the electric telescopic rod 23 through the control system, and the micro pressure sensor 24 is set with a pressure range through the control system.

[0025] When the micro pressure sensor 24 detects that the pressure is too high and is not within the normal pressure range, the pressure applied by the single-strand wire 13 to the guide wheel 29 is large, and the tension of the single-strand wire 13 exceeds the limit. Then the micro pressure sensor 24 transmits an electrical signal to the control system, and the electric telescopic rod 23 is driven by the control system to retract the output shaft, and the guide wheel 29 is moved toward the center of the circle of the wire drum 11. Then the single-strand wire 13 that conflicts with the guide wheel 29 is synchronously moved toward the center of the circle of the wire drum 11, and the tension exceeding the limit of the single-strand wire 13 is alleviated, and the single-strand wire 13 is caused to relax, that is, the pressure applied by the single-strand wire 13 to the guide wheel 29 will be reduced compared to when the tension exceeds the limit. When the micro pressure sensor 24 detects that the pressure is within the normal range, the control system stops the contraction of the telescopic shaft of the electric telescopic rod 23, and stabilizes the position of the single-strand wire 13 with adjusted tension.

[0026] When the micro pressure sensor 24 detects that the pressure is too low and is not within the normal pressure range, the pressure applied by the single-strand wire 13 to the guide wheel 29 is small, and the single-strand wire 13 is too loose. Then the micro pressure sensor 24 transmits an electrical signal to the control system, and the electric telescopic rod 23 is driven by the control system to extend the output shaft, and the guide wheel 29 moves away from the center of the circle of the wire drum 11, so that the guide wheel 29 drives the single-strand wire 13 to move synchronously, causing the single-strand wire 13 to be tightened. When the micro pressure sensor 24 detects that the pressure is within the normal range, the control system stops the extension of the telescopic shaft of the electric telescopic rod 23, and stabilizes the position of the single-strand wire 13 whose tension has been adjusted.

[0027] In summary: In the traditional stranding process, unbalanced single-wire tension can easily lead to structural defects such as back strands and loose strands, and even technical problems such as wire breakage due to excessive tension. The tension adaptation component can automatically adjust the position of the guide wheel 29 according to the real-time tension of the single-strand wire 13, dynamically balance the tension of the single-strand wire 13, and ensure that the tension of the single-strand wire 13 is always maintained in the ideal range during the twisting process, avoiding being pulled apart by excessive tension or deformed by excessive looseness. Accurate tension control can reduce defects such as back strands and loose strands, and ensure the consistency of the physical structure of the network cable; at the same time, stable tension helps to optimize the twisting pitch and direction, improve the electrical performance of the network cable, and meet the requirements of the intelligent power distribution system for high-frequency data transmission cables.

[0028] Among them: reference Figures 7 to 9 As shown, the L-shaped bracket 25 is divided into a vertical surface and a horizontal surface. A square groove is provided on the vertical surface of the L-shaped bracket 25. The square groove of the L-shaped bracket 25 is snap-fitted with the square plate 26. The square plate 26, the circular plate 27, the central axis 28, and the threaded column 210 constitute a special-shaped shaft. The threaded column 210 is detachably connected to the L-shaped bracket 25 through a nut. In actual use, the circular plate 27 and the nut respectively contact and fit on both sides of the vertical surface of the L-shaped bracket 25, and the axial direction of the special-shaped shaft is limited by the tightening of the nut, ensuring that the special-shaped shaft will not affect the axial stability of the special-shaped shaft when the guide wheel 29 is driven to rotate by the single strand 13. At the same time, the square shape design of the square groove of the L-shaped bracket 25 and the square plate 26 is to prevent the rotation of the guide wheel 29 from affecting the tightening state of the nut of the special-shaped shaft, ensuring that the radial direction of the special-shaped shaft is limited.

[0029] In the prior art, the material and wire diameter of the single-strand wire 13 will change, and the guide wheel 29 that supports and guides the single-strand wire 13 needs to be replaced according to the changes of the single-strand wire 13. When the guide wheel 29 needs to be replaced, the user loosens the nut and removes the nut on the threaded column 210, removes the guide wheel 29 and the special-shaped shaft from the L-shaped bracket 25, and then installs the guide wheel 29 of corresponding material and size on the L-shaped bracket 25, and tightens the nut thread to ensure the stability of the guide wheel 29 and the special-shaped shaft, thereby achieving rapid replacement of the guide wheel 29.

[0030] In summary: by achieving rapid replacement of the guide wheel 29, the characteristics of different single-strand wires 13 can be quickly matched. For single-strand wires 13 with large differences in hardness such as copper core, aluminum core, and optical fiber, the guide wheels 29 with different surface roughness can be quickly replaced to avoid problems such as scratches on the surface of the single-strand wire 13 and peeling of the coating due to material mismatch, thereby ensuring the electrical performance of the cable wire.

[0031] At the same time, when a guide wheel 29 on the cable drum 11 is abnormally worn or stuck, the detachable design allows the faulty component to be replaced individually, avoiding safety accidents such as full line shutdown or wire breakage caused by local problems, ensuring production continuity, and improving the production efficiency of multiple categories of cable and network cables.

[0032] It should be added that: multiple wire-releasing troughs 21 are evenly opened on the wire drum 11, but not every wire-releasing trough 21 is provided with an L-shaped bottom plate 22. The function is: since the number of stranded wires in the production of network cables is volatile, the user can strand the single strands 13 according to the needs, use the corresponding number and position of wire-releasing troughs 21, and install the L-shaped bottom plate 22 inside the wire-releasing trough 21 at the corresponding position through bolts, so that the tension adaptation component can correspond to the actual number of strands of the single strands 13, avoiding the waste of setting multiple tension adaptation components when the number of strands of the single strands 13 is small, and the position and usage quantity of the tension adaptation component can be freely controlled by the user, thereby improving the comprehensiveness and versatility of the use of the tension adaptation component.

[0033] In summary, compared with the existing technology, the tension adaptation component can realize adaptive adjustment of the tension of the single strand 13, and quickly and more quickly correspond to the material and size of the guide wheel 29 according to actual usage. It can also realize the position and usage quantity of the tension adaptation component by the user, thereby improving the comprehensiveness and versatility of the tension adaptation component.

[0034] Example 2: Reference Figure 1 、 Figure 2 as well as Figure 4 、 Figure 5 As shown, a glue coating and rolling assembly is provided on the stranding frame 12, and the glue coating and rolling assembly includes a support plate 31, which is fixedly connected to the side of the stranding frame 12 away from the wire drum 11, and the top of the support plate 31 away from the stranding frame 12 is fixedly connected to an annular shell 32, and the inner wall of the annular shell 32 is symmetrically connected to two side plates 33, and the top of the annular shell 32 is fixedly connected to a liquid pipe 34, and the outer surface of the side plate 33 close to the stranding frame 12 is fixedly connected to a synchronous hollow ring 35, and the side of the stranding frame 12 close to the annular shell 32 is fixedly connected to a servo motor 36, and the servo motor 36 is divided into a fixed end and an output shaft. The output shaft of the servo motor 36 is connected to the synchronous hollow ring 35 through a synchronous wheel transmission with a synchronous belt 37, and the side of the two side plates 33 close to each other is fixedly connected to a middle tube 38, and the inner surface of the middle tube 38 is fixedly connected to a rubber ring 39.

[0035] The top end of the liquid pipe 34 is externally connected to a glue delivery device and may also be externally connected to a suction pump.

[0036] Among them: reference Figure 5As shown, a plurality of leakage holes are provided on the middle tube 38 and the rubber ring 39. The annular shell 32, the two side plates 33, the middle tube 38, the rubber ring 39, and the synchronous hollow ring 35 are all sleeved on the network cable core wire 14, and the network cable core wire 14 is located at the center position of the annular shell 32, the two side plates 33, the middle tube 38, the rubber ring 39, and the synchronous hollow ring 35.

[0037] Among them: reference Figure 5 As shown, the rubber material of the rubber ring 39 has a deformable property, so that the rubber ring 39 can resist and fit the network cable core wire 14. The purpose is to enable the glue-coated and rolled assembly to adapt to network cable core wires 14 of different diameters. The servo motor 36 is electrically connected to the external remote control.

[0038] It should be noted that the rotation direction of the output shaft of the servo motor 36 is consistent with the rotation direction of the cable drum 11 , that is, the rotation direction of the output shaft of the servo motor 36 is the plying direction of the network cable core wires 14 .

[0039] It should be noted that: Figure 5 As shown, the two side plates 33 , the middle tube 38 and the annular shell 32 together form a hollow cavity, which is communicated with the outside through a leakage hole jointly provided on the middle tube 38 and the rubber ring 39 .

[0040] When the glue coating and rolling assembly is in use, the end of the network cable core wire 14 away from the wire drum 11 is pulled toward the side away from the wire drum 11 by the traction device. That is, at this time, the network cable core wire 14 passes through the annular shell 32, the two side plates 33, the middle tube 38, the rubber ring 39, and the synchronous hollow ring 35 toward the side away from the wire drum 11, and the network cable core wire 14 squeezes the rubber ring 39, causing the rubber ring 39 to produce elastic deformation.

[0041] At this time, the user starts the external glue delivery device and the servo motor 36 through the remote control. As the external glue delivery device is started, the glue inside the external glue delivery device is able to flow through the liquid pipe 34 into the cavity formed by the two side plates 33, the middle pipe 38 and the annular shell 32. The glue gradually fills the cavity and is coated on the network cable core wire 14 through the leakage holes jointly opened on the middle pipe 38 and the rubber ring 39.

[0042] As the servo motor 36 is started, the output shaft of the servo motor 36 drives the synchronous hollow ring 35 to rotate synchronously through the synchronous belt 37, and the synchronous hollow ring 35 drives the adjacent side plates 33 to rotate synchronously, and the two side plates 33 are connected by the middle tube 38, so that the two side plates 33, the middle tube 38 and the rubber ring 39 all rotate synchronously, and the rotation direction of the two side plates 33, the middle tube 38 and the rubber ring 39 is the plying direction of the network cable core wire 14, that is, when the rubber ring 39 is in contact with the network cable core wire 14, the rubber ring 39 rotates along the distribution direction of the multiple single strands 13 on the network cable core wire 14.

[0043] In summary, as the glue coating and rolling assembly operates, the middle tube 38 can rotate with the mesh cable core wire 14 as the rotation axis, and glue is applied to the mesh cable core wire 14 during the rotation process. At the same time, the rubber ring 39 rotates along the distribution direction of multiple single strands 13 on the mesh cable core wire 14.

[0044] In summary, the glue coating and rolling component rotates and applies glue along the distribution direction of multiple single strands 13 on the network cable core wire 14, so that the coated glue is filled into the gap of the network cable core wire 14 after the twisted structure along the spiral direction of the twisted structure, avoiding the "blind spot" of static spraying in the existing technology. At the same time, when the middle tube 38 rotates, it can achieve 360-degree uniform coverage of the network cable core wire 14, avoiding the uneven thickness caused by traditional one-sided spraying in the technology, and the glue overflowing and dripping caused by excessive one-sided spraying.

[0045] At the same time, the rubber ring 39 rotates and collides along the distribution direction of the multiple single wires 13 on the network cable core wire 14, and the rubber ring 39 fills into the gap of the network cable core wire 14 along the twisted spiral direction, and "kneads" the glue into the spiral gap of the multi-layer twisted wire. After the network cable core wire 14 passes through the rubber ring 39, the excess glue on the surface of the network cable core wire 14 can be scraped off to avoid excess glue on the surface of the network cable core wire 14 after the network cable core wire 14 is twisted.

[0046] Furthermore, when the device is not in use, the liquid pipe 34 can be connected to an external suction pump to extract and discharge excess glue in the cavity formed by the liquid pipe 34 , the two side plates 33 , the middle pipe 38 and the annular shell 32 .

[0047] In summary, compared with the existing technology, the glue coating and rolling assembly can realize active rotary gluing and the rotation direction is consistent with the direction of the twisted wire, ensuring that the glue fills the gap along the thread direction.
