Description

Technical Field

[0001] This invention relates to the field of fiber wrapping machine technology, and in particular to a vertical fiber wrapping machine. Background Technology

[0002] Optical fiber is a type of fiber made of glass or plastic. It is a light transmission tool that uses the principle of total internal reflection to transmit light within these fibers. To ensure the stability of the optical signal propagation in the fiber core, a cladding and protective layer need to be wrapped around the fiber core. Common manufacturers generally use wrapping tape to wrap the outside of the optical fiber, which can ensure that the optical signal is enclosed in the fiber core during use and protect the optical fiber for easy wrapping of the protective layer. However, because optical fibers are too thin, the wrapping tape will apply a large torque to the optical fiber when using a wrapping machine, making the optical fiber prone to rotation or even breakage, thus affecting the stability of the optical fiber cladding.

[0003] To address the aforementioned technical problems, Chinese patent CN214956196U discloses a high-speed optical fiber drawing and stranding machine, comprising an optical fiber material pay-off frame, a wrapping machine, an armoring machine, traction rollers, and a take-up shaft. The optical fiber material pay-off frame includes a mounting plate with an equal number of staggered first placement shafts and covering material placement shafts. The first placement shafts and covering material placement shafts are located on opposite ends of the mounting plate and are perpendicularly connected to the mounting plate. A wrapping machine is installed at one end of the mounting plate with the covering material placement shafts. An armoring machine is installed at the output end of the wrapping machine, and a traction roller is installed at the output end of the armoring machine. A take-up shaft is installed in the output direction of the traction rollers. This invention is used to strand optical fibers into multiple strands, but it cannot overcome the problem of self-rotation caused by the excessively small diameter of the optical fiber during the winding process.

[0004] Therefore, it is necessary for those skilled in the art to provide a vertical fiber wrapping machine to prevent the fiber from rotating during the wrapping process and to improve the stability and efficiency of the wrapping. Summary of the Invention

[0005] The purpose of this invention is to provide a vertical optical fiber wrapping machine to solve the technical problem that in the prior art, when the wrapping machine wraps the optical fiber, the wrapping tape applies a large torque to the optical fiber, which makes the optical fiber easy to rotate or even break, thus affecting the stability of the optical fiber wrapping layer.

[0006] The technical solution adopted by this invention to solve its technical problem is: a vertical optical fiber wrapping machine, used to wrap the wrapping tape on the tape roll onto the optical fiber. The vertical optical fiber wrapping machine includes a main shaft, a drive mechanism, a wrapping mechanism, a traction mechanism, and a tension mechanism. The drive mechanism is located at one end of the main shaft, and the traction mechanism is located at the other end of the main shaft. The wrapping mechanism is rotatably mounted on the main shaft and located between the drive mechanism and the traction mechanism. The wrapping mechanism is rotatably mounted on the main shaft. The tape roll is mounted on a mandrel. The mandrel is rotatably provided inside the main shaft. A fixing tube is connected to the mandrel. The optical fiber is located inside the fixing tube. The fixing tube has a hollow tubular structure. Molds are threaded to both ends of the fixing tube. The molds have fine holes that mate with the optical fiber. The diameter of the fine holes is smaller than the inner diameter of the fixing tube, and the length of the fine holes is smaller than the length of the molds.

[0007] Furthermore, the mold is cylindrical, and a conical surface is provided inside the mold, with the conical surface coinciding with the axis of the fine hole.

[0008] Furthermore, the wrapping mechanism includes a disc fixedly connected to one end of the main shaft and a first guide roller rotatably mounted on the disc. The disc has a waist-shaped groove and a driven gear rotatably mounted on it, with a potentiometer connected to the driven gear. The tension mechanism includes a synchronous wheel and a tension motor. The synchronous wheel is rotatably mounted on the main shaft and is driven to rotate by the tension motor. A connecting rod is threaded onto the synchronous wheel, passing through the waist-shaped groove and rotatable relative to it. A driving gear is mounted on one end of the connecting rod, meshing with the driven gear. A rocker arm is fixedly mounted on the driving gear, and a second guide roller is rotatably mounted on the rocker arm. The wrapping tape on the wrapping roll is wound sequentially around the first and second guide rollers. The tension motor and the potentiometer are both electrically connected to the controller.

[0009] Furthermore, a ceramic brake is connected to the tension motor, and the drive gear is in the form of an incomplete gear mechanism.

[0010] Furthermore, the wrapping mechanism also includes a baffle and a fixing frame. The baffle is mounted on the mandrel and abuts against the shoulder of the mandrel. The wrapping tape roll is sleeved on the mandrel and abuts against the baffle. The fixing frame is sleeved outside the cable conduit and presses the wrapping tape roll. The disc body is provided with a fixing post. One end of the fixing post is threaded to the disc body, and the other end of the fixing post is threaded to a fly ring. Both ends of the fixing frame are threadedly fixed to the fly ring using bolts or screws or other fasteners.

[0011] Furthermore, the fixed frame is provided with multiple mounting slots, which penetrate the wall of the fixed frame, and guide posts are detachably connected inside the mounting slots; the fixed frame is provided with mounting holes, and mounting openings are provided on the fixed frame along the radial direction of the mounting holes, which penetrate the wall between the inner wall of the mounting holes and the fixed frame; a locking threaded hole is provided on the side of the fixed frame, and the axis of the locking threaded hole is perpendicular to the symmetry plane of the mounting opening.

[0012] Furthermore, the vertical fiber optic wrapping machine also includes a housing, in which the drive mechanism, wrapping mechanism, and tension mechanism are all fixedly installed, and the traction mechanism is located at the top of the housing.

[0013] Furthermore, the traction mechanism includes a traction wheel, a clamping belt, a cylinder, and a traction motor. The traction wheel is fixedly connected to the rotating shaft of the traction motor, the end of the clamping belt is fixedly connected to the telescopic end of the cylinder, the clamping belt abuts against the traction wheel, and the optical fiber is located between the traction wheel and the clamping belt.

[0014] Furthermore, the drive mechanism includes a first drive motor and a second drive motor, a first drive wheel is sleeved on the main shaft, a second drive wheel is sleeved on the spindle, the first drive motor is belt-connected to the first drive wheel, and the second drive motor is belt-connected to the second drive wheel.

[0015] The beneficial effects of this invention are:

[0016] This invention features a fine hole on the fixing tube, matching the diameter of the optical fiber, for clamping the fiber and preventing its rotation without hindering its movement. During use, the synchronous wheel, drive gear, and controller are interconnected and rotate to dynamically adjust the wrapping tape tension, ensuring tension stability during operation, preventing excessive stretching and wear of the wrapping tape, and improving the production quality of optical fiber products. A ceramic brake is connected to the tension motor for more precise control and adjustment of its rotation, achieving efficient and accurate adjustment of the wrapping tape tension. The drive gear eliminates teeth on both sides that do not require meshing, making the meshing between the drive and driven gears more accurate and reducing processing costs. Compared to existing technologies, this invention adds a fixing tube and a mold inside the mandrel. The fine hole in the mold provides higher friction for the optical fiber, facilitating clamping and preventing rotation within the fixing tube, thus improving operational stability.

[0028] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0029] Please see Figure 2 , Figure 3 , Figure 4The present invention provides a vertical fiber optic wrapping machine for wrapping tape on a tape roll 201 onto an optical fiber. The vertical fiber optic wrapping machine includes a main shaft 60, a drive mechanism 10, a wrapping mechanism 20, a traction mechanism 30, and a tension mechanism 40. The drive mechanism 10 is located at one end of the main shaft 60, and the traction mechanism 30 is located at the other end of the main shaft 60. The wrapping mechanism 20 is rotatably mounted on the main shaft 60 and located between the drive mechanism 10 and the traction mechanism 30.

[0030] In use, the main shaft 60 is vertically arranged, the optical fiber passes through the main shaft 60 and is connected to the traction mechanism 30. The traction mechanism 30 pulls the optical fiber up and down, while the drive mechanism 10 drives the main shaft 60 to rotate and drives the wrapping mechanism 20 to rotate together, thereby wrapping the wrapping tape on the wrapping tape roll 201 around the optical fiber. During the wrapping tape roll 201 winding process, the tension mechanism 40 is used to adjust the tightness of the wrapping tape to ensure that the wrapping tape can be firmly wrapped around the optical fiber.

[0031] Further, please refer to Figure 2 , Figure 4 , Figure 5 , Figure 7 The wrapping mechanism 20 includes a disc body 21 fixedly connected to one end of the main shaft 60 and a first guide roller 22 rotatably mounted on the disc body 21. The disc body 21 has a waist-shaped groove 203, and a driven gear 45 is rotatably mounted on the disc body 21. A potentiometer 46 is connected to the driven gear 45. The tension mechanism 40 includes a synchronous pulley 41 and a tension motor 42. The synchronous pulley 41 is rotatably mounted on the main shaft 60 and is driven to rotate by the tension motor 42. A connecting rod 43 is threaded onto the upper part of the connecting rod 43, which passes through the waist-shaped groove 203 and can rotate relative to the waist-shaped groove 203. A drive gear 44 is installed at one end of the connecting rod 43, and the drive gear 44 meshes with the driven gear 45. A rocker arm 47 is fixedly installed on the drive gear 44, and a second guide roller 48 is rotatably installed on the rocker arm 47. The wrapping tape on the wrapping tape roll 201 is wound around the first guide roller 22 and the second guide roller 48 in sequence. The tension motor 42 and the potentiometer 46 are both electrically connected to the controller (not shown in the figure).

[0032] Understandably, the controller refers to a master control device that controls the starting, speed regulation, braking, and reversing of the motor by changing the wiring of the main circuit or control circuit and changing the resistance value in the circuit in a predetermined sequence.

[0033] In use, the main shaft 60 rotates under the drive of the drive mechanism 10, which in turn drives the wrapping mechanism 20 to rotate. The tension motor 42 drives the synchronous wheel 41 to rotate, which in turn drives the connecting rod 43 and the drive gear 44 to rotate together. When the tension of the wrapping tape increases due to the decrease in the diameter of the wrapping tape roll 201, the controller controls the tension motor 42 to change its speed. The speed of the connecting rod 43 changes accordingly, causing the connecting rod 43 to rotate a certain angle within the waist-shaped groove 203. At this time, the swing rod 47 and the second guide roller 48 deflect along with the connecting rod 43, reducing the distance between the first guide roller 22 and the second guide roller 48, thereby reducing the tension of the wrapping tape. At the same time, the drive gear 44 also deflects at a certain angle, thereby changing the rotation speed of the driven gear 45. The change in the speed of the driven gear 45 causes the potentiometer 46 to output an analog signal to the controller. The controller controls the speed of the take-up motor according to the analog signal, thereby controlling the take-up speed and reducing the take-up speed to adapt to the gradually decreasing wrapping tape release speed. This invention utilizes the interconnection and rotation of the synchronous wheel 41, the drive gear 44, and the controller to achieve dynamic adjustment of the tape tension, ensuring the stability of the tension during use, preventing the tape from being excessively stretched or worn, and improving the production quality of optical fiber products.

[0034] In this embodiment, a ceramic brake is connected to the tension motor 42 to more accurately control and adjust the rotation of the tension motor 42, thereby achieving efficient and accurate adjustment of the tension of the strap.

[0035] In this embodiment, the driving gear 44 is in the form of an incomplete gear mechanism. Since the driving gear 44 rotates at a small angle, only some teeth will mesh with the driven gear 45. Therefore, the teeth on both sides of the driving gear 44 that do not require meshing are removed, so that the driving gear 44 can mesh with the driven gear 45 more accurately, thereby reducing processing costs and improving the performance.

[0036] Please see Figure 5 , Figure 6 , Figure 7 The main shaft 60 has a rotatable mandrel 61 inside, and a fixed tube 62 is connected inside the mandrel 61. The optical fiber is located inside the fixed tube 62. The wrapping mechanism 20 is rotatably mounted on the main shaft 60, and the wrapping tape roll 201 is mounted on the mandrel 61. In use, the mandrel 61 drives the wrapping tape roll 201 to rotate, and the main shaft 20 drives the wrapping mechanism 20 to rotate together. Under the drive of the mandrel 61, the wrapping tape roll 201 realizes the active tape release function, effectively preventing the wrapping tape from being excessively stretched or worn, and ensuring the performance of the wrapping tape.

[0037] Furthermore, the wrapping mechanism 20 also includes a baffle 23 and a fixing frame 24. The baffle 23 is mounted on the spindle 61 and abuts against the shoulder of the spindle 61. The wrapping tape roll 201 is sleeved on the spindle 61 and abuts against the baffle 23. The fixing frame 24 is sleeved on the wire guide tube 62 and presses the wrapping tape roll 201. The disc body 21 is provided with a fixing post 204. One end of the fixing post 204 is threaded to the disc body 21, and the other end of the fixing post 204 is threaded to a fly ring 25. Both ends of the fixing frame 24 are threadedly fixed to the fly ring 25 using bolts or screws or other fasteners.

[0038] In use, the fixing frame 24 abuts against the tape roll 201, fixing the tape roll 201 to the mandrel 61. At the same time, the fixing frame 24 is threaded onto the fly ring 25, thereby ensuring the stability of the tape roll 201 during installation.

[0039] Specifically, the fixed frame 24 is provided with multiple mounting slots 26, which penetrate the wall of the fixed frame 24. Guide posts 27 are detachably connected to the mounting slots 26 using fasteners such as bolts or screws. The fixed frame 24 is provided with mounting holes 241, and mounting openings 242 are provided along the radial direction of the mounting holes 241. The mounting openings 242 penetrate the wall between the inner wall of the mounting holes 241 and the fixed frame 24. Thus, when the mounting openings 242 are closed, the diameter of the mounting holes 241 decreases, and when the mounting openings 242 are open, the diameter of the mounting holes 241 increases. Locking threaded holes 243 are provided on the side of the fixed frame 24, and the axis of the locking threaded holes 243 is perpendicular to the plane of symmetry of the mounting openings 242.

[0040] In use, the fixing frame 24 is fitted over the fixing tube 62, and bolts or screws or other fasteners are threaded into the locking threaded hole 243 to close the installation opening 242, thereby locking the fixing frame 24 to the outside of the fixing tube 62, thus achieving quick installation of the fixing frame 24.

[0041] Furthermore, the guide post 27 is rotatably mounted on the fixed frame 24. After being tensioned by the first guide roller 22 and the second guide roller 48, the tape passes through the guide post 27 in sequence and is finally wound around the cable core. The guide post 27 can guide the release of the tape, which is beneficial for the tape to be wound around the cable core.

[0042] In this embodiment, the first guide rollers 22 are arranged in pairs, and there are two pairs. Each time they are used, only the two first guide rollers 22 on one pair are active. When wrapping the tape, one end of the tape goes around one of the first guide rollers 22 and then around the second guide roller 48, then around the other first guide roller 22, and then around the guide post 27. Figure 10 The direction indicated by the middle arrow is a schematic diagram of how the strap is wrapped.

[0043] Please see Figure 8 , Figure 9 The fixing tube 62 has a hollow tubular structure, and both ends of the fixing tube 62 are threadedly connected to molds 63. The molds 63 are cylindrical and have fine holes 64 inside. The fine holes 64 cooperate with the optical fiber. In use, the optical fiber is inserted into the fixing tube 62 through the fine hole 64 of one mold 63 and exits through the fine hole 64 of the other mold 63. The fine holes 64 on the molds 63 provide high friction for the optical fiber, which facilitates clamping the optical fiber, prevents the optical fiber from rotating inside the fixing tube 62, and improves the stability of use. In this invention, the molds 63 for fixing the optical fiber are detachably set on the fixing tube 62, which facilitates the replacement of different specifications, increases the processing range, and facilitates replacement.

[0044] Furthermore, the mold 63 is provided with a conical surface 65, which faces the optical fiber installation direction and coincides with the axis of the fine hole 64. The present invention provides a conical surface 65 on the surface of the mold 63 where the optical fiber enters, so as to improve the convenience of optical fiber installation and facilitate the control of the length of the fine hole 64, thereby improving the portability of processing. Preferably, the tolerance between the optical fiber and the fine hole 64 is less than or equal to 0.02 mm.

[0045] In this embodiment, the diameter of the fine hole 64 is smaller than the inner diameter of the fixing tube 62, and the length of the fine hole 64 is smaller than the length of the mold 63. Since the fine hole 64 clamps the optical fiber by friction, the magnitude of the friction force can be accurately controlled by controlling the length of the fine hole 64 to prevent excessive friction force from affecting the movement of the optical fiber.

[0046] Furthermore, please refer again. Figure 4 , Figure 5 , Figure 8 The fixed tube 62 is also equipped with a limiting post 202, and a gap (not shown in the figure) is formed on the limiting post 202. The gap is connected to the fine hole 64. After the optical fiber passes through the mold 63, it enters the gap. After passing through the guide post 27, the wrapping tape passes through the gap and wraps around the outside of the optical fiber to complete the wrapping tape.

[0047] Please see Figure 1 , Figure 2 , Figure 3 The vertical fiber optic wrapping machine also includes a housing 50. The drive mechanism 10, wrapping mechanism 20, and tension mechanism 40 are all fixedly installed inside the housing 50. The traction mechanism 30 is located at the top of the housing 50. In use, the fiber optic cable is installed from the bottom of the housing 50 into the cable conduit 62, and then the traction mechanism 30 is used to pull the fiber optic cable out from the top of the housing 50.

[0048] In this embodiment, the traction mechanism 30 includes a traction wheel 32, a clamping belt 33, a cylinder 31, and a traction motor 34. The traction wheel 32 is fixedly connected to the rotating shaft of the traction motor 34. The end of the clamping belt 33 is fixedly connected to the telescopic end of the cylinder 31. The clamping belt 33 abuts against the traction wheel 32, and the optical fiber is located between the traction wheel 32 and the clamping belt 33. The clamping belt 33 includes a support body (not shown in the figure), two drive wheels (not shown in the figure) rotatably mounted on the support body, and a conveyor belt (not shown in the figure) sleeved on the two drive wheels. The cylinder 31 controls the clamping belt 33 to abut against the traction wheel 32, thereby clamping the optical fiber and improving the stability of traction. The traction motor 34 drives the traction wheel 32 to rotate, thereby driving the conveyor belt on the clamping belt 33 to move. The optical fiber located between the traction wheel 32 and the clamping belt 33 moves together, thereby achieving traction of the optical fiber.

[0049] In use, the optical fiber is placed between the traction wheel 32 and the clamping belt 33. The cylinder 31 is started, so that the clamping belt 33 abuts against the traction wheel 32 and clamps the optical fiber onto the traction wheel 32. The traction motor 34 is started, and the clamping belt 33 rotates accordingly, which in turn drives the traction wheel 32 to rotate. The optical fiber located between the traction wheel 32 and the clamping belt 33 also moves accordingly, thus achieving the traction of the optical fiber.

[0050] In another embodiment, the traction mechanism 30 is a take-up drum, and the end of the optical fiber is fixedly connected to the take-up drum. By rotating the take-up drum, the wrapped cable can be wound up.

[0051] Further, please refer to Figure 2 , Figure 3 , Figure 4 The drive mechanism 10 includes a first drive motor 11 and a second drive motor 12. A first drive wheel 13 is sleeved on the main shaft 60, and a second drive wheel 14 is sleeved on the spindle 61. The first drive motor 11 is connected to the first drive wheel 13 by a belt, and the second drive motor 12 is connected to the second drive wheel 14 by a belt. In use, the first drive motor 11 drives the main shaft 60 to rotate, and the second drive motor 12 drives the spindle 61 to rotate, thereby realizing power output.

[0052] The specific usage of this invention is as follows: Step 1: Insert the optical fiber from the lower part of the outer shell 50. The end of the optical fiber passes through the fine hole 64 of one mold 63 into the fixed tube 62 and exits through the fine hole 64 of another mold 63. Place the end of the optical fiber between the traction wheel 32 and the clamping belt 33. Start the cylinder 31 so that the clamping belt 33 abuts against the traction wheel 32 and presses the optical fiber onto the traction wheel 32. Start the traction motor 34, and the traction wheel 32 rotates accordingly, thereby driving the clamping belt 33 to rotate. The optical fiber located between the traction wheel 32 and the clamping belt 33 also moves accordingly, realizing the installation and traction of the optical fiber.

[0053] Step 2: Start the first drive motor 11 and the second drive motor 12. The first drive motor 11 drives the main shaft 60 to rotate, and the second drive motor 12 drives the mandrel 61 to rotate. The mandrel 10 drives the wrapping tape roll 201 to rotate, and the main shaft 20 drives the wrapping mechanism 20 to rotate together. The wrapping tape roll 201 actively releases the tape under the drive of the mandrel 10, thereby wrapping the tape around the optical fiber. Start the tension motor 42 to adjust the tightness of the wrapping tape and complete the wrapping of the cable.

[0054] This invention utilizes the interconnected rotation of a synchronous pulley 41, a drive gear 44, and a controller to achieve dynamic adjustment of the wrapping tape tension, ensuring tension stability during use, preventing excessive stretching and wear of the wrapping tape, and improving the production quality of optical fiber products. A ceramic brake 43 is connected to the tension motor 42 for more precise control and adjustment of its rotation, achieving efficient and accurate tension adjustment of the wrapping tape. The drive gear 44 eliminates the non-contact teeth on both sides, making the meshing between the drive gear 44 and the driven gear 45 more accurate, while reducing processing costs. Compared with existing technologies, this invention adds a fixing tube 62 and a mold 63 inside the mandrel 61. The fine holes 64 on the mold 63 provide higher friction for the optical fiber, preventing it from rotating within the fixing tube 62 and improving stability during use.

[0055] It is understood that the present invention has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the invention. Furthermore, under the teachings of the present invention, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of the present invention.
