Description

Technical Field

[0001] This invention relates to the field of optical cable manufacturing technology, and in particular to a stranding device with an extended structural design. Background Technology

[0002] Optical cables are mainly composed of optical fibers, plastic protective sheaths, and plastic outer jackets. They are communication cable assemblies that use one or more optical fibers placed in the protective sheath as the transmission medium and can be used individually or in groups. The basic structure of an optical cable generally consists of several parts, including the cable core, reinforcing steel wires, filler, and sheath. In addition, depending on the requirements, there may be waterproof layers, buffer layers, insulated metal conductors, and other components.

[0003] In the fiber optic cable manufacturing process, stranding devices are used to wind and fix multiple strands of cable to form a whole. Currently, most stranding devices used in fiber optic cables have a fixed structure and cannot be adjusted according to the number, diameter, and position of strands, resulting in a limited range of applications. They also cannot adjust the distance between stranded cables in real time during the stranding process. Stranding equipment is exposed when not in use, leading to a limited lifespan. Furthermore, fiber optic cable grease cannot be directly and evenly filled into the cable during stranding, requiring subsequent operations, which involve numerous procedures and high processing costs. Summary of the Invention

[0004] The technical problem to be solved by this invention is that most stranding devices currently used in optical cables have fixed structures and cannot be adjusted according to the number, diameter and position of strands in the optical cable, resulting in a limited range of applications. The stranding equipment is directly exposed when not in use, resulting in a limited service life. Moreover, optical cable grease filling is required in the later stage, which involves many procedures and high processing costs.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a stranding device with an extended structure design, including a main frame, a drive motor, a first body and a second body mounted on the main frame, a lateral mounting cover for mounting the drive motor fixedly mounted on the outer side of the first body, a centrally located wire through hole opened inside the first body and the centrally located wire through hole of the first body is installed with an electrically controlled telescopic limiting guide stranding component, and a lateral storage groove for internally installing a flipping guide device is opened on the left side wall of the second body, and the drive motor is connected to the electrically controlled telescopic limiting guide stranding component through a belt drive pulley assembly.

[0006] The upper surface of the main frame is equipped with a horizontal guide tube for connecting the first body and the second body via a mounting bracket. The first body and the second body are movably assembled with the main frame via lateral mounting tubes on both sides of the lower end, which are sleeved on the outside of the horizontal guide tube.

[0007] An annular lateral mounting groove is provided on the right side wall of the first body, which is connected to the centrally placed through hole.

[0008] The electrically controlled telescopic limiting guide twisting assembly includes an inner drive ring movably installed inside the annular lateral assembly groove, an electrically controlled telescopic support rod fixed on the side wall of the inner drive ring, an inner extrusion limiting frame axially fixed on the telescopic section of the electrically controlled telescopic support rod, an arc-shaped lateral extrusion frame fixed on both sides of the inner extrusion limiting frame, and an inclined guide wheel installed on the inner extrusion limiting frame.

[0009] The right side wall of the first machine body is fixedly fitted with an external limiting cover for limiting the electrically controlled telescopic limiting guide twisting assembly at the opening of the annular lateral assembly groove.

[0010] The flip-type material guide device includes a flip-type wire bracket movably assembled in a lateral storage groove and a side-mounted flip-type support rod movably installed inside the lateral storage groove for controlling the flip-type wire bracket to flip.

[0011] An arc-shaped assembly frame is fixedly mounted on the side wall of the internal extrusion limiting frame, located around the electrically controlled telescopic support rod. A side guide rod is fixedly mounted on the side wall of the arc-shaped assembly frame. A side guide tube that cooperates with the side guide rod is fixed on the outside of the internal extrusion limiting frame.

[0012] The transverse guide tube is internally fitted with a built-in electrically controlled adjusting screw. The outer side of the transverse guide tube has a strip-shaped transition opening at the end of the lateral assembly tube. The inner side of the lateral assembly tube has an internal threaded mounting seat that is threadedly assembled with the built-in electrically controlled adjusting screw.

[0013] An annular guide groove is provided on the inner side of the central through hole of the first machine body. An annular cover is installed inside the annular guide groove. The annular cover is fixedly assembled with the outer side of the internal extrusion limiting frame through a lateral assembly bracket. A scraping brush is installed on the side wall of the annular cover. An upper feed pipe is fixed on the upper surface of the first machine body. A lower discharge pipe is fixed on the lower surface of the first machine body. An upper guide flow channel communicating with the inside of the upper feed pipe is provided on the top surface of the annular guide groove. A lower guide flow channel communicating with the inside of the lower discharge pipe is provided on the bottom surface of the annular guide groove.

[0014] The beneficial effects of this invention are:

[0015] (1) The twisting device with an extension structure design of the present invention adopts a split structure design, connecting the first body and the second body to the horizontal guide tube on the upper surface of the main frame. The distance between the first body and the second body can be adjusted as needed, thereby improving the applicability range. Moreover, it can be stored when not in use, improving the durability of the twisting adjustment device.

[0016] (2) An electrically controlled telescopic limiting guide twisting assembly is installed inside the centrally placed wire through hole of the first body. By telescopically extending inside the centrally placed wire through hole, the cable is adapted and limited, thus making it suitable for different cable diameters and improving applicability.

[0017] (3) The drive motor installed on the outside of the first machine body drives the belt drive wheel assembly to drive the electronically controlled telescopic limiting guide twisting assembly, which can greatly improve the twisting efficiency and improve the synchronization. At the same time, the staggered arc-shaped lateral extrusion frame and the inclined guide wheel installed on the internal extrusion limiting frame reduce the friction while ensuring the fit.

[0018] (4) Optical cable grease can be evenly applied to the cable during the stranding process, reducing the subsequent processes and production costs.

[0019] (5) A flip-type material guide device is installed inside the lateral storage groove on the left side wall of the second body, which can increase the number of cables wound by flipping.

[0020] (6) The electrically controlled telescopic limiting guide twisting assembly with a detachable structure design facilitates later maintenance and reduces later usage costs;

[0021] (7) The first body and the second body are adjusted by the built-in electronically controlled adjusting screw located inside the horizontal guide tube, which can change the distance between them in real time, greatly improving the guiding and limiting performance.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0030] Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The stranding device shown includes a main frame 1, a drive motor 2, a first body 3 and a second body 4 mounted on the main frame 1. A lateral mounting cover 5 for mounting the drive motor 2 is fixedly mounted on the outer side of the first body 3. Both the first body 3 and the second body 4 have a centrally located wire through hole 6. An electrically controlled telescopic limiting guide stranding assembly is installed inside the centrally located wire through hole 6 of the first body 3. A lateral storage groove 7 for mounting a flipping guide device is opened on the left side wall of the second body 4. The drive motor 2 is connected to the electrically controlled telescopic limiting guide stranding assembly through a belt drive pulley assembly 8.

[0031] To facilitate lateral assembly, the upper surface of the main frame 1 is fitted with a horizontal guide tube 9 for connecting the first body 3 and the second body 4 via a mounting bracket. The first body 3 and the second body 4 are movably assembled with the main frame 1 via lateral mounting tubes 10 on both sides of the lower end, which are fitted around the outside of the horizontal guide tube 9.

[0032] The second body 4 consists of an outer shell 41 with a horizontally fixed guide tube 9 on the outside and an internal wire-holding cylinder 42 movably installed inside the outer shell 41. The internal wire-holding cylinder 42 has a horizontally placed wire-holding through hole inside, and a lateral receiving groove 7 is formed on the left outer wall of the internal wire-holding cylinder 42. The outer shell 41 movably limits the internal wire-holding cylinder 42 inside by lateral closing flanges 43 on both sides.

[0033] To facilitate lateral assembly, an annular lateral assembly groove 100 is provided on the right side wall of the first body 3, which is connected to the centrally located through hole 6.

[0034] To facilitate rotation and telescopic control, the electrically controlled telescopic limiting guide twisting assembly includes an inner drive ring 11 movably installed inside the annular lateral assembly groove 100, an electrically controlled telescopic support rod 12 fixed on the side wall of the inner drive ring 11, an inner extrusion limiting frame 13 axially fixed on the telescopic section of the electrically controlled telescopic support rod 12, an arc-shaped lateral extrusion frame 14 fixed on both sides of the inner extrusion limiting frame 13 with offset arrangement, and an inclined guide wheel 15 installed on the inner extrusion limiting frame 13.

[0035] The drive motor 2 is connected to the electrically controlled telescopic limiting guide twisting assembly via the transmission belt on the belt drive pulley assembly 8, which is sleeved on the annular pulley on the inner side of the inner drive ring 11. An inner transition groove for storing the transmission belt is provided inside the first body 3.

[0036] The electrically controlled telescopic support rod 12 is existing technology. By extending its telescopic section, it controls the internal extrusion limiting frame 13 to extend into the centrally placed wire through hole 6. The arc-shaped lateral extrusion frames on both sides of its extrusion surface cooperate with the adjacent arc-shaped lateral extrusion frames to extrude and limit the cable. Then, it rotates in the same direction as the built-in wire-holding drum.

[0037] To facilitate the lateral limiting assembly, an external limiting cover 16 for limiting the electrically controlled telescopic limiting guide twisting assembly is fixedly mounted on the right side wall of the first body 3 at the opening position of the annular lateral assembly groove 10.

[0038] To facilitate the flipping adjustment, the flipping guide device includes a flipping wire bracket 17 movably mounted in the lateral storage groove 7 and a side-mounted flipping support rod 18 movably mounted inside the lateral storage groove 7 for controlling the flipping of the flipping wire bracket 17.

[0039] The flip-type cable holder 17 has three circular cable placement holes 171. An internal adjustment port 172 with a transverse mounting shaft is opened on the side wall of the flip-type cable holder 17. An external fitting 173 for connecting the internal adjustment port 172 is axially fixed to the top of the telescopic rod of the existing side-mounted flip-type support rod 18. The side-mounted flip-type support rod 18 is movably connected to the flip-type cable holder 17 by the external fitting 173 being sleeved on the outside of the transverse mounting shaft. The side-mounted flip-type support rod 18 controls the flip-type cable holder 17 to flip and adjust by telescoping. The flip-type cable holder 17 flips outward so that the three circular cable placement holes 171 inside are at different heights, thereby facilitating the wiring of different cables.

[0040] In order to cooperate with the inner guide and improve the bending resistance of the inner extrusion limiting frame 13, an arc-shaped assembly frame 19 is fixedly installed on the side wall of the inner extrusion limiting frame 13 around the electric telescopic support rod 12. A side guide rod 20 is fixedly installed on the side wall of the arc-shaped assembly frame 19. A side guide tube 21 that cooperates with the side guide rod 20 is fixed on the outside of the inner extrusion limiting frame 13.

[0041] To facilitate translation adjustment, a built-in electrically controlled adjusting screw 22 is movably mounted inside the horizontal guide tube 9. A strip-shaped transition port is opened on the outer side of the horizontal guide tube 9 at the assembly end of the lateral mounting tube 10. An internal threaded mounting seat 23 is provided on the inner side of the lateral mounting tube 10 for threaded assembly with the built-in electrically controlled adjusting screw 22.

[0042] The built-in electronically controlled adjusting screw 22 is existing technology. It consists of a screw drive motor 221 fixed on the outside of the horizontal guide tube 9 and a horizontal screw 222 movably assembled inside the horizontal guide tube 9. The screw drive motor 221 and the horizontal screw 222 are connected by a transmission gear assembly. The screw drive motor 221 drives the horizontal screw 222 to drive the internal thread mounting seat 23 to move externally.

[0043] To facilitate the application of grease to the cable, an annular guide groove 24 is provided on the inner side of the central cable through hole 6 of the first body 3. An annular cover 25 is installed inside the annular guide groove 24. The annular cover 25 is fixedly assembled with the outer side of the internal extrusion limiting frame 13 via a lateral mounting bracket 26. A scraper brush 27 is installed on the side wall of the annular cover 25. An upper feed pipe 28 is fixed on the upper surface of the first body 3, and a lower discharge pipe 29 is fixed on the lower surface of the first body 3. An upper guide flow channel 30, which communicates with the interior of the upper feed pipe 28, is provided on the inner top surface of the annular guide groove 24. A lower guide flow channel 31, which communicates with the interior of the lower discharge pipe 29, is provided on the inner bottom surface of the annular guide groove 24.

[0044] The external oil supply pipe is connected to the upper feed pipe 28, and the cable grease is fed into the annular guide trough 24 through the upper guide channel 30. The grease is squeezed into the scraper brush 27 through the guide port at the connection end of the scraper brush 27. Then, the annular cover 25 rotates to drive the scraper brush 27 to move in a circle along the cable, so that the grease inside is evenly applied to the cable. Then, the excess grease can flow back into the annular guide trough 24 through the guide port, and finally flow into the lower guide channel 31 due to gravity, and finally be discharged from the lower discharge pipe 29.

[0045] Twisting method: The core wire passes through the central wire through hole 6 inside the first body 3 and the second body 4, and then the outer cable passes through the horizontal wire through hole. Then, the flip-type wire bracket 17 is flipped and adjusted by adjusting the extension and retraction of the side-mounted flip support rod 18, so that the three circular wire through holes inside the flip-type wire bracket 17 are at different heights, which facilitates the wiring of the outer cable in the horizontal wire through hole through the circular wire through hole at different positions. Then, the electrically controlled telescopic support rod 12 drives the internal extrusion limit frame 13, the arc-shaped side extrusion frame 14 and the inclined guide wheel 15 to extrude into the central wire through hole 6, thereby extruding the outer cable to the outside of the core wire. Then, the built-in wire drum 42 is rotated to perform the twisting operation.

[0046] A horizontal telescopic synchronizing rod can be fixed on the outside of the inner drive ring 11. A side guide blind hole that cooperates with the horizontal telescopic synchronizing rod is opened inside the built-in wire-holding drum 42. The horizontal telescopic synchronizing rod is inserted into the side guide blind hole to ensure that the inner drive ring 11 and the built-in wire-holding drum 42 rotate synchronously in the same direction.

[0047] To facilitate lateral assembly, an annular lateral assembly groove 10 is provided on the right side wall of the first body 3, which is connected to the centrally located through hole 6.

[0048] To facilitate rotation and telescopic control, the electrically controlled telescopic limit guide twisting assembly includes a component movably mounted inside the annular lateral mounting groove 10.
