Description

Technical Field

[0001] The present invention relates to the technical field of optical cables, and in particular to a high-efficiency transmission dual-core optical cable and a forming device thereof. Background Art

[0002] Since the application of optical cables in the 1970s, they have now developed into the backbone of wired transmission such as long-distance trunk lines, urban telephone relays, underwater and submarine communications, local area networks, and private networks. They have also begun to develop into user access networks, from fiber to the roadside, fiber to the building, etc. to fiber to the home. Dual-core optical fiber is a special optical fiber with a special refractive index distribution. Dual-core optical fiber contains two fiber cores in the same cladding, and each core is an optical waveguide, that is, two single-core optical fibers are integrated in a dual-core optical fiber. It breaks through the refractive index distribution structure of conventional optical fibers and arranges two parallel fiber cores in the same optical fiber. It can be used as an optical transmission medium and can also be used to construct new optical devices.

[0003] Since optical cables are often exposed to various complex environmental conditions in actual applications, such as damp underground pipelines, rainy outdoor environments, and areas where water may accumulate, ordinary optical cables lack effective waterproofing measures, allowing external moisture to easily enter the interior of the optical cable, especially into the structural layer that wraps the optical fiber. Once moisture penetrates, it will cause the transmission performance of the optical fiber to deteriorate, such as increasing the attenuation of the optical signal, seriously affecting the accurate and efficient transmission of data. It will also accelerate the aging and damage of other components inside the optical cable, reducing the service life of the optical cable. Summary of the Invention

[0038] 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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] Example:

[0040] See also Figure 1The present invention provides a technical solution: a high-efficiency transmission dual-core optical cable, comprising an optical fiber 1 and an outer sheath layer 6, two optical fibers 1 are arranged inside the outer sheath layer 6, a loose tube 2 is arranged on the outside of the optical fiber 1, and a waterproof layer 3 is arranged on the outside of the loose tube 2. A buffer layer 5, a braided layer 4 and an inner lining layer 7 are arranged in sequence from the outside to the inside in the outer sheath layer 6, the two optical fibers 1 are arranged in the inner lining layer 7, and the two optical fibers 1 do not contact each other in the inner lining layer 7.

[0041] The waterproof layer 3 on the outside of the loose tube 2 can effectively prevent moisture in the external environment from entering the inside of the loose tube 2. The waterproof layer 3 on the outside can resist the intrusion of moisture at the first time, protect the optical fiber 1 and the filling material in the loose tube 2 from moisture, thereby ensuring that the transmission performance of the optical fiber 1 is not affected. The braided layer 4 can prevent the optical cable from being damaged by external mechanical forces such as extrusion and collision. When encountering stones on the ground, heavy objects in construction or other possible collision situations, the braided layer 4 can effectively disperse these external forces and protect the optical fiber core inside the optical cable from damage. It is like putting on a layer of solid armor for the optical cable, which greatly enhances the optical cable's resistance to mechanical damage. At the same time, when the optical cable is stretched, the braided layer 4 can provide a certain tensile strength and can also play a role in electromagnetic shielding. The buffer layer 5 can further disperse external impacts.

[0042] The inner lining layer 7 can provide buffering protection for the optical fiber 1 inside the optical cable, isolate the optical fiber 1 from other components in the optical cable, and prevent water vapor from entering the area around the optical fiber 1. The outer sheath layer 6 can effectively resist damage to the optical cable caused by external mechanical forces, disperse external forces, and prevent damage to the internal structure of the optical cable.

[0043] The waterproof layer 3, the braided layer 4, the buffer layer 5, the outer sheath layer 6 and the inner lining layer 7 effectively increase the efficient transmission of the dual-core optical cable.

[0044] See also Figure 2-Figure 12 The present invention provides a technical solution: a molding device for a high-efficiency transmission dual-core optical cable, which is used to produce a high-efficiency transmission dual-core optical cable, including a workbench 8, a grease storage cylinder 9 is fixedly installed on the workbench 8, a connecting frame 10 is fixedly installed below the grease storage cylinder 9, and a grease discharge port 29 is opened through the connecting frame 10, the optical fiber 1 is located above the workbench 8 and below the grease discharge port 29, an anti-blocking component is provided in the connecting frame 10, and the anti-blocking component cleans the grease discharge port 29 to prevent the grease discharge port 29 from being blocked.

[0045] The anti-blocking component includes a pin 40 and a bevel groove 41. The pin 40 moves up and down in the bevel groove 41 to clear the grease discharge port 29 to prevent the grease discharge port 29 from being blocked. At the same time, the bevel groove 41 can also prevent the grease from being retained above the grease discharge port 29.

[0046] In this embodiment, a guide and traction mechanism 42 is provided on the workbench 8, and a mounting frame 14 is fixedly installed. A rotating disk 13 is fixedly installed on the guide and traction mechanism 42, and a reciprocating motion component 11 is provided on the mounting frame 14. The guide and traction mechanism 42 drives the optical fiber 1 to be transported and provides power to the reciprocating motion component 11 through the rotating disk 13.

[0047] The guide and traction mechanism 42 includes a working motor, a worm gear, a worm and a guide roller. The optical fiber 1 is located in the guide roller and moves in one direction in the guide and traction mechanism 42. The working motor drives the worm to rotate, and drives the guide roller to rotate through the worm gear. The rotation directions of the two adjacent guide rollers are opposite. At the same time, one of the guide rollers will also drive the rotating disk 13 to rotate when it rotates, and the connection between the second connecting column 16 and the rotating disk 13 deviates from the center axis of the rotating disk 13. In this way, when the rotating disk 13 rotates, it will drive the first sliding block 15 to move back and forth on the mounting frame 14 through the second connecting column 16.

[0048] The reciprocating motion assembly 11 includes a first connecting column 12, a first sliding block 15, a second connecting column 16 and a third connecting column 17. The first sliding block 15 moves back and forth on the mounting frame 14. The first connecting column 12 is fixedly installed on the side of the first sliding block 15. The second connecting column 16 and the third connecting column 17 are movably installed on both sides of the first sliding block 15.

[0049] In this embodiment, the ends of the first connecting column 12 are respectively fixedly installed with a moving frame 26 and a connecting plate 27, and the moving frame 26 and the connecting plate 27 are both located below the connecting frame 10. The fixed column 24 and the inclined block 25 are respectively fixedly installed below the connecting frame 10, and the third sliding block 34 and the extrusion spring 35 are respectively movably installed in the connecting plate 27. The extrusion spring 35 is located above the third sliding block 34, and the end of the third sliding block 34 is fixedly connected to the movable plate 28. A rack column 36 is movably installed on the movable plate 28, and a sliding groove 37 matching the rack column 36 is opened. When the movable plate 28 moves, the rack column 36 can always slide in the sliding groove 37 to prevent the rack column 36 from separating from the connecting frame 10.

[0050] The inner cavity of the grease storage cylinder 9 is communicated with the inner cavity of the connecting frame 10 , and the grease can flow out from the grease discharge port 29 of the connecting frame 10 .

[0051] In this embodiment, a rotating gear 38 and a rack plate 39 are movably installed inside the connecting frame 10, and the rack plate 39 is fixedly connected to the ejector pin 40. The rack column 36 and the rack plate 39 are both meshed with each other about the rotating gear 38, and the rack column 36 and the rack plate 39 are symmetrical about the center of the rotating gear 38. The movable plate 28 and the inclined surface block 25 are in contact through the inclined surface. When the movable plate 28 moves horizontally, the inclined surface and the inclined surface block 25 are released, and the movable plate 28 drives the third sliding block 34 to squeeze the extrusion spring 35. When the rack column 36 moves upward, it will drive the rack plate 39 to move in the opposite direction by rotating the gear 38. In this way, when the rack plate 39 moves, it will drive the ejector pin 40 to enter the grease discharge port 29 in the connecting frame 10, thereby promoting the grease in the grease discharge port 29 to flow out onto the optical fiber 1, making it easier for the wiping roller 30 to wipe the grease on the optical fiber 1. In this way, the surface of the optical fiber 1 will be filled with grease by the wiping roller 30, and the grease will be prevented from blocking the grease discharge port 29.

[0052] The width of the rack plate 39 is greater than the width of the inclined groove 41 to prevent the ointment from flowing out.

[0053] In this embodiment, a fixed block 31 is fixedly installed in the moving frame 26, and a fan-shaped column 32 is movably installed in the fixed block 31. Wiping rollers 30 are fixedly installed on both side ends of the fan-shaped column 32. The optical fiber 1 passes through the wiping roller 30. There are two groups of wiping rollers 30. The starting position of one group of wiping rollers 30 is located directly below the grease discharge port 29 and is provided with a notch. The other group is rotationally symmetrically distributed next to it, that is, the two adjacent groups of wiping rollers 30 are staggered. The moving frame 26 is provided with a rotating groove 33 required for the rotation of the wiping roller 30. The wiping roller 30 is located on the surface of the optical fiber 1. The wiping roller 30 rotates around the optical fiber 1 when moving, and the rotating groove 33 facilitates the rotation and wiping of the wiping roller 30.

[0054] In this embodiment, the fixed column 24 passes through the fan-shaped column 32, and the fixed column 24 is inclined below the connecting frame 10. When the fan-shaped column 32 moves on the fixed column 24, it drives the wiping roller 30 to rotate, thereby promoting full contact between the grease and the optical fiber 1. When the moving frame 26 moves, it will drive the fixed block 31 to move together, and the fan-shaped column 32 inside the fixed block 31 will move together. At the same time, the fan-shaped column 32 is located on the outside of the fixed column 24. In this way, the fan-shaped column 32 will rotate around the optical fiber 1 when it moves, that is, it will wipe the grease on the surface of the optical fiber 1, so that the surface of the optical fiber 1 is coated with grease.

[0055] In this embodiment, a piston plate 20 is movably installed in the grease storage cylinder 9, and a cam rotating shaft 19 is provided on the piston plate 20. A rotating wheel is fixedly installed on the central axis of the cam rotating shaft 19. When the rotating wheel rotates, it will drive the cam rotating shaft 19 to rotate, and drive the piston plate 20 to move up and down. When the piston plate 20 moves up and down, it will drive the piston column 21 to move back and forth up and down. A second sliding block 18 is movably installed at the end of the third connecting column 17. The second sliding block 18 is located on the grease storage cylinder 9 and is in sliding contact with the inner wall of the grease storage cylinder 9, that is, the second sliding block 18 is always located on the grease storage cylinder 9 and in contact with the rotating wheel. A tooth block portion is fixedly installed on one side of the second sliding block 18, and the tooth block portion is meshedly connected with the rotating wheel, that is, the second sliding block 18 can drive the cam rotating shaft 19 to rotate through the rotating wheel.

[0056] In this embodiment, a piston column 21 is fixedly installed at the bottom end of the piston plate 20. The piston plate 20 is located outside the inner cavity of the grease storage cylinder 9. The piston column 21 is located above the grease discharge port 29, and a piston block is fixedly installed at the bottom end of the piston column 21. The piston block can squeeze out the grease in the grease storage cylinder 9 through the grease discharge port 29. At the same time, a stirring plate 22 is movably installed on the outside of the piston column 21, and a connecting groove 23 for the stirring plate 22 to stir the grease is provided on the piston column 21. The connecting groove 23 is inclined on the piston column 21. During the up and down movement of the piston column 21, the stirring plate 22 will be driven to rotate in the grease storage cylinder 9 through the connecting groove 23, thereby improving the fluidity of the grease.

[0057] An anti-blocking component is provided, including a pin 40 and a bevel groove 41. The pin 40 moves up and down in the bevel groove 41 to clear the grease discharge port 29 to prevent it from being blocked, ensuring that the grease can flow smoothly onto the optical fiber 1, facilitating subsequent processing operations.

[0058] The coordinated movement of the various components in the reciprocating motion assembly 11 causes the piston plate 20 to move up and down, driving the stirring plate 22 to stir the ointment to improve the fluidity of the ointment. At the same time, the piston column 21 squeezes the ointment out of the discharge port 291 and drops it on the optical fiber 1; the moving frame 26 drives the wiping roller 30 to apply and evenly spread the ointment on the surface of the optical fiber 1, ensuring that the entire surface of the optical fiber 1 is coated with ointment, avoiding the situation where there is no ointment coverage, thereby ensuring the uniformity and stability of the ointment application during the optical cable production process and improving the production quality of the optical cable.

[0059] The working principle of this embodiment is as follows: when in use, the optical fiber 1 is driven to transmit through the guide traction mechanism 42, and the guide traction mechanism 42 also drives the rotating disk 13 to rotate. When the rotating disk 13 rotates, it drives the second connecting column 16 to reciprocate on the mounting frame 14. When the second connecting column 16 moves, it drives the first connecting column 12 and the third connecting column 17 to reciprocate together through the first sliding block 15. When the third connecting column 17 moves, it drives the cam rotating shaft 19 to rotate through the second sliding block 18, and drives the piston plate 20 to reciprocate up and down. At the same time, the piston column 21 will also move up and down in the grease storage tube 9. In this way, the piston column 21 will drive the stirring plate 22 to rotate up and down in the inner cavity of the grease storage tube 9 through the connecting groove 23 during the up and down movement, thereby driving the grease in the grease storage tube 9 to flow. At the same time, during the up and down movement of the piston column 21, the piston block will also cause the ointment to flow out through the grease discharge port 29 and fall on the upper surface of the optical fiber 1.

[0060] At the same time, during the reciprocating movement of the first connecting column 12, it will drive the moving frame 26 and the connecting plate 27 to move reciprocally. When the moving frame 26 moves, it will drive the wiping roller 30 to apply the ointment to the surface of the optical fiber 1. When the moving frame 26 moves, the fan-shaped column 32 inside it will rotate under the action of the fixed column 24, and the two sets of wiping rollers 30 will cooperate with each other to evenly spread the ointment on the surface of the optical fiber 1, so that the surface of the optical fiber 1 is completely coated with the ointment, to prevent the surface of the optical fiber 1 from not being completely coated with the ointment.

[0061] During the movement of the connecting plate 27, the movable plate 28 will change its horizontal height through the cooperation of the inclined block 25. When the movable plate 28 moves toward the side of the inclined block 25, the extrusion spring 35 will be squeezed by the third sliding block 34, and the rack column 36 will also move in the sliding groove 37. At the same time, when the horizontal height of the movable plate 28 increases, the rack column 36 will also increase and will drive the rack plate 39 to move downward by rotating the gear 38. During the downward movement of the rack plate 39, the ejector pin 40 will be driven to enter the grease discharge port 29 to clear the grease discharge port 29.

[0062] As the reciprocating assembly 11 moves back and forth, the ejector pin 40 will continue to unscrew and clear the ointment discharge port 29 to prevent the ointment discharge port 29 from being blocked. At the same time, the wiping roller 30 will continue to apply and evenly spread the ointment on the surface of the optical fiber 1 to prevent the surface of the optical fiber 1 from being covered with ointment.

[0063] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
