Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of optical cable production, and particularly relates to a production device for composite optical fiber embedded steel wire rope and a use method thereof. BACKGROUND

[0002] At present, in the production process of composite optical fiber, a steel wire rope needs to be embedded in the composite optical fiber (a steel wire rope is wound outside an optical fiber assembly) to improve the mechanical properties and transmission stability of the composite optical fiber, and therefore a winding production device needs to be used.

[0003] However, the existing winding production device is inconvenient for real-time detection of dynamic tension change in the steel wire rope winding process when the steel wire rope is wound. When there is a slight difference in the material quality of the steel wire rope or the unwinding speed fluctuates, the actual tension deviates from the preset value. If the tension is too large, the internal optical fiber assembly is excessively pressed, which increases the optical fiber micro-bending loss and even causes the optical fiber to break. If the tension is too small, the steel wire rope and the optical fiber assembly are loosely attached, and in subsequent use, relative friction is easily generated due to vibration, which causes the optical fiber outer sheath to wear and reduces the overall tensile strength of the composite structure.

[0004] In addition, in the traction conveying process of the optical fiber assembly, radial deviation is easily generated due to the coaxiality deviation of the traction device, guide rail vibration or gravity sag of the optical fiber assembly itself, so that the central axis of the steel wire rope winding device and the central axis of the optical fiber assembly are difficult to coincide, which causes the "partial winding" phenomenon to occur when the steel wire rope is wound. The partial winding part easily forms a stress concentration point, and long-term use may cause the steel wire rope to break or the optical fiber to be damaged by fatigue, which seriously affects the service life of the product.

[0005] Therefore, a production device for composite optical fiber embedded steel wire rope and a use method thereof are provided. SUMMARY

[0019] A use method of a production equipment for a composite optical fiber embedded steel wire rope, the use method comprising the following steps:

[0020] S1: The staff fixes the mounting plate on the composite optical fiber production line, passes the optical fiber assembly extended by the optical fiber preparation device through the hollow positioning ring and the support column, and connects the end with the traction device.

[0025] Compared with the prior art, the beneficial effects of the present application are:

[0026] 1. By setting the wireless pressure sensor in the tensioning force self-adjusting mechanism, the tensioning force of the steel wire rope can be monitored in real time, and the relative position of the anti-falling guide roller and the optical fiber assembly can be accurately adjusted by combining the dynamic extension of the wireless electric push rod: when the tensioning force of the steel wire rope is too large, the tensioning force is reduced by shortening the guide path to avoid micro-bending loss or breakage of the optical fiber assembly due to excessive extrusion; when the tensioning force is too small, the tensioning force is increased by lengthening the guide path to prevent friction and wear or decrease in tensile strength caused by loose fit of the steel wire rope and the optical fiber assembly, effectively adapting to variables such as differences in steel wire rope material and speed fluctuations during unwinding, ensuring that the tensioning force during winding is always within a reasonable range, and improving the stability and consistency of the composite structure.

[0027] 2. By setting the coaxiality positioning mechanism, the magnetic repulsion force of the energized magnetic block and the permanent magnetic block is used to drive the positioning roller to uniformly clamp the optical fiber assembly from all around, and the anti-interference displacement sensor is used to capture the radial deviation in real time and dynamically correct it, so that the optical fiber assembly always maintains the axial position and provides a stable reference for the steel wire rope winding; when the optical fiber assembly deviates due to vibration or uneven tensioning force, not only will the clamping correction of the positioning roller be triggered, but also the relative path of the steel wire rope and the optical fiber assembly in different directions will be changed, causing the tensioning force self-adjusting mechanism to respond, which not only eliminates the risk of partial winding, but also avoids the vicious cycle of tensioning force imbalance caused by deviation.

[0028] 3. By setting the traction speed detection mechanism, due to the synchronous rotation of the wheel body and the optical fiber assembly, the encoder converts the mechanical rotation speed into a pulse signal to accurately perceive the traction speed; when the speed fluctuates, the PLC controller can link the motor speed of the rotating mechanism to adjust, so that the rotation speed of the rotating frame and the moving speed of the optical fiber assembly are matched in real time, ensuring the uniformity of the steel wire rope winding interval, further ensuring the structural consistency and mechanical property stability of the composite optical fiber, and improving the controllability of the production process.

[0038] Rotating mechanism 6 is arranged between the side surface of support plate 2 and rotating frame 4, and rotating mechanism 6 is used for driving a plurality of pay-off racks 5 to rotate and winding steel wire rope on optical fiber assembly; Rotating mechanism 6 includes motor 61 fixedly arranged on the side surface of support plate 2, the output end of motor 61 is fixedly provided with gear 62, the circumferential wall of rotating frame 4 is fixedly provided with gear ring 63, gear 62 and gear ring 63 are engaged, motor 61 can drive gear 62 to rotate, gear 62 can drive gear ring 63 to rotate, so that rotating frame 4 and a plurality of pay-off racks 5 on the side wall thereof rotate together and wind steel wire rope on the outer wall of optical fiber assembly, since a plurality of pay-off racks 5 are rotating, when the steel wire rope reel sleeved on wire reel shaft 52 rotates, there will be slight shaking, which causes the steel wire rope to swing irregularly, so that the tension fluctuation of steel wire rope occurs, but the tension fluctuation is small and can be ignored within a reasonable tension range.

[0039] A plurality of tension self-adjusting mechanisms 7 are fixedly arranged on the inner side wall of the rotating frame 4 in a uniform distribution around, and the positions of the plurality of tension self-adjusting mechanisms 7 are arranged one by one corresponding to the positions of the plurality of pay-off frames 5. A battery pack for supplying power to the tension self-adjusting mechanism 7 is installed on the rotating frame 4, so that the tension self-adjusting mechanism 7 does not need to be connected with the power supply outside the equipment through wiring. The tension self-adjusting mechanism 7 comprises an L-shaped fixed plate 71 fixedly arranged on the inner side wall of the rotating frame 4. A wireless electric push rod 72 is fixedly arranged on the side of the L-shaped fixed plate 71 away from the rotating frame 4. A plug sleeve 73 is fixedly arranged on the moving end of the wireless electric push rod 72. A plug block 74 is slidably arranged in the plug sleeve 73. An anti-falling guide roller 75 is fixedly arranged on the top of the plug block 74.

A wireless pressure sensor 76 is fixedly arranged on the bottom of the plug block 74. An elastic expansion rod 77 is fixedly arranged between the bottom of the wireless pressure sensor 76 and the inner wall of the plug sleeve 73. Since the wireless electric push rod 72 and the wireless pressure sensor 76 will produce centrifugal motion, it is necessary to strengthen the element fixation, fill the buffer with potting glue, and perform early screening, regular maintenance, so as to reduce the influence of high-speed rotating centrifugal force on the internal elements of the wireless electric push rod 72 and the wireless pressure sensor 76, and ensure the stability of signal transmission.

[0040] The coaxiality positioning mechanism 8 is arranged on the side wall of the support column 3, and the center of the coaxiality positioning mechanism 8 is aligned with the center of the support column 3. The inside of the coaxiality positioning mechanism 8 is provided with the optical fiber assembly. The coaxiality positioning mechanism 8 comprises two fixed rods 81 fixedly arranged symmetrically on the side wall of the support column 3. The same hollow positioning ring 82 is fixedly arranged on the end of the two fixed rods 81 away from the support column 3. A plurality of evenly distributed positioning sleeves 83 are fixedly arranged on the inner side wall of the hollow positioning ring 82. A positioning rod 84 extending outward is slidably arranged in each of the plurality of positioning sleeves 83. A power-on electromagnetic block 85 is fixedly arranged on the inner wall of the positioning sleeve 83.

An anti-interference displacement sensor 89 is fixedly arranged between the positioning rod 84 and the permanent magnet block 86. A metal shielding shell is additionally arranged outside the anti-interference displacement sensor 89, which can avoid the influence of electromagnetic interference on the internal elements. When the current of the power-on electromagnetic block 85 decreases, the elastic force of the spring 87 will drive the permanent magnet block 86 to move towards the power-on electromagnetic block 85. At this time, the contact external force between the positioning roller 88 and the optical fiber assembly is reduced.

[0041] The traction speed detection mechanism 9 is arranged in the coaxial positioning mechanism 8, and the traction speed detection mechanism 9 is used for detecting the traction speed of the optical fiber assembly; the traction speed detection mechanism 9 comprises a shell 91 fixedly arranged at the end of the positioning rod 84, a wheel body 92 rotatably arranged in the shell 91, a mounting groove 93 is arranged on one side of the bottom of the shell 91, and an encoder 94 is fixedly arranged in the mounting groove 93; the rotating end of the encoder 94 is fixedly connected with one end of the rotating shaft of the wheel body 92; the wheel body 92 adopts an antiskid rubber wheel, so that the wheel body 92 and the outer wall of the optical fiber assembly cannot slip, the synchronous movement of the wheel body 92 and the optical fiber assembly is ensured, when the wheel body 92 rotates, the rotating end of the encoder 94 is driven to rotate together with the rotating shaft, the rotating speed of the wheel body 92 can be detected, and the traction speed of the optical fiber assembly can be indirectly reflected.

[0042] The PLC controller 10 is fixedly arranged on the side of the support plate 2, and the rotating mechanism 6, the tension self-adjusting mechanism 7, the coaxial positioning mechanism 8 and the traction speed detection mechanism 9 are electrically connected with the PLC controller 10.

[0043] The operating principle of the present application is described as follows: the staff fixes the mounting plate 1 on the composite optical fiber production line, the winding production equipment is located between the traction device and the optical fiber preparation device, and forms a complete production link, then the staff passes the optical fiber assembly extended from the optical fiber preparation device through the inside of the hollow positioning ring 82 and the inside of the support column 3, ensures that the end of the optical fiber assembly is connected with the traction device, at the same time, the staff installs a plurality of steel wire rope reels on a plurality of wire feeding racks 5, and then pulls one end of the steel wire rope, so that the steel wire rope is sequentially passed through the inside of the corresponding guide ring 11 and the anti-falling guide roller 75, and the running direction of the steel wire rope is ensured to be accurate, finally, the ends of the plurality of steel wire ropes are wound on the outer wall of the optical fiber assembly.

[0044] When the traction device pulls the optical fiber assembly, the staff operates the PLC controller 10 to start the motor 61, the motor 61 rotates to drive the gear 62 to rotate, the rotation of the gear 62 drives the gear ring 63 to rotate, so that the rotating frame 4 rotates on the outer wall of the support column 3, with the rotation of the rotating frame 4, the plurality of wire feeding racks 5 mounted thereon also rotate, so that the steel wire ropes on the plurality of wire feeding racks 5 can be synchronously wound on the outer wall of the optical fiber assembly, at the same time, the steel wire rope reel will automatically rotate in the wire feeding rack 5 due to the winding of one end of the steel wire rope on the optical fiber assembly.

[0045] In the process of winding, the external force received by the steel wire rope acts on the anti-falling guide roller 75, so that the anti-falling guide roller 75 drives the plug 74 to move in the inside of the plug sleeve 73, at the same time, the plug 74 will extrude the wireless pressure sensor 76, so that the wireless pressure sensor 76 moves downward against the elastic force of the elastic expansion rod 77, at this time, the wireless pressure sensor 76 can detect the tension of the steel wire rope in real time, and send the detected pressure value of the steel wire rope to the PLC controller 10 through the Bluetooth wireless module;

[0046] If the pressure value is larger, exceeds the threshold value preset in the PLC controller 10, it indicates that the tension of the steel wire rope is larger, and the pressure of the steel wire rope wound on the outer wall of the optical fiber assembly is also larger, at this time, the PLC controller 10 will immediately control the wireless electric push rod 72 to perform the retracting action, so that the anti-falling guide roller 75 moves towards the position of the optical fiber assembly, thereby reducing the tension of the steel wire rope and the pressure of the steel wire rope wound on the outer wall of the optical fiber assembly, so that the pressure detection value of the wireless pressure sensor 76 returns to the appropriate interval, avoiding the adverse effects on the optical fiber assembly due to over-winding;

[0047] If the pressure value decreases, exceeds the threshold value preset in the PLC controller 10, it indicates that the tension of the steel wire rope is smaller, and the steel wire rope wound on the outer wall of the optical fiber assembly is looser, at this time, the PLC controller 10 will immediately control the wireless electric push rod 72 to perform the extending action through the Bluetooth wireless module, so that the anti-falling guide roller 75 moves away from the position of the optical fiber assembly, thereby increasing the tension of the steel wire rope and the pressure of the steel wire rope wound on the outer wall of the optical fiber assembly, so that the pressure detection value of the wireless pressure sensor 76 returns to the appropriate interval, avoiding the loose winding condition, and ensuring the quality and stability of the product;

[0048] In the process of traction winding, the staff operates the PLC controller 10 to start the tension self-adjusting mechanism 7, so that the plurality of energized magnetic blocks 85 simultaneously access the same current, the energized magnetic blocks 85 after energization immediately generate a magnetic repulsion force to the permanent magnetic blocks 86, under the action of the magnetic repulsion force, the plurality of permanent magnetic blocks 86 overcome the elastic force of the springs 87, drive the positioning rods 84 and the positioning rollers 88 at the end to stretch out from the inside of the hollow positioning ring 82, until the plurality of positioning rollers 88 contact with the outer wall of the optical fiber assembly, complete the positioning of the optical fiber assembly, so that the optical fiber assembly can maintain the coaxiality through the support column 3 inside, providing a stable reference for the subsequent uniform winding of the steel wire rope;

[0049] If the fiber assembly deviates due to vibration during traction, the positioning roller 88 on one side of the deviation direction will bear greater pressure, thereby driving the corresponding positioning rod 84 to retract into the positioning sleeve 83. As the positioning rod 84 retracts, the permanent magnet block 86 gradually approaches the energized electromagnetic block 85, while compressing the spring 87. At this time, the anti-interference displacement sensor 89 installed at the end of the positioning rod 84 will sense this position change and immediately feedback an electrical signal to the PLC controller 10. After receiving the signal, the PLC controller 10 will quickly increase the current of the energized electromagnetic block 85 to enhance its magnetic repulsive force. Under the action of the enhanced repulsive force, the positioning rod 84 drives the positioning roller 88 to apply a reverse thrust force to the fiber assembly, gradually forcing the fiber assembly to return to the center position of the support column 3, ensuring that the winding process is not affected by the deviation;

[0050] When the fiber assembly deviates, it will cause the relative positions of the steel wires in different directions to change with respect to the fiber assembly. The steel wire in the deviation direction will have a sudden increase in tension due to the shortening of the path between it and the fiber assembly, while the steel wire in the opposite direction will have a sudden decrease in tension due to the lengthening of the path between it and the fiber assembly. In addition, the anti-falling guide roller 75 in the tension self-adjusting mechanism 7 will be subjected to abnormal force, driving the insert block 74 to move within the insert sleeve 73 and compressing the wireless pressure sensor 76. After the wireless pressure sensor 76 transmits the pressure signal to the PLC controller 10, the PLC controller 10 simultaneously controls the wireless electric push rod 72 on the corresponding L-shaped fixed plate 71 to act: for the steel wire with excessive tension, control the wireless electric push rod 72 to retract, so that the anti-falling guide roller 75 approaches the fiber assembly to reduce the tension; for the steel wire with insufficient tension, control the wireless electric push rod 72 to extend, so that the anti-falling guide roller 75 moves away from the fiber assembly to increase the tension;

[0051] If the steel wire has uneven tension due to material differences or unwinding fluctuations (such as a steel wire being too tight), the wireless pressure sensor 76 of the tension self-adjusting mechanism 7 will first detect the abnormality, and the PLC controller 10 will first adjust the tension of the steel wire through the wireless electric push rod 72. If the uneven tension is not completely corrected, the over-tight steel wire will pull the fiber assembly to one side, at which time the positioning roller 88 of the coaxial positioning mechanism 8 will sense the deviation, and the energized electromagnetic block 85 and the permanent magnet block 86 will push the positioning rod 84, with the symmetric positioning roller 88 thrust force canceling the lateral tension of the steel wire, pulling the fiber assembly back to the center. At the same time, the tension self-adjusting mechanism 7 will again fine-tune the tension of each steel wire based on the corrected position, ensuring that the tension of all steel wires is compatible with the center positioning of the fiber assembly;

[0052] The coaxiality positioning mechanism 8 provides a stable reference for winding by correcting and preventing the tension of the anti-falling guide roller 75 from falling off through the center of the positioning roller 88, and the tension self-adjusting mechanism 7 dynamically adapts to the positioning changes, both of which are coordinated by the PLC controller 10 to avoid tension imbalance caused by deviation and deviation aggravation caused by uneven tension, thereby ensuring the uniformity and stability of the steel wire winding on the outer wall of the optical fiber assembly;

[0053] After positioning is completed, the optical fiber assembly is pulled forward, and the wheel body 92 in contact with the optical fiber assembly rotates synchronously with the movement of the optical fiber assembly. When the wheel body 92 rotates, the rotating shaft drives the rotating end of the encoder 94 to rotate. The encoder 94 works with the photoelectric detection device through the internal grating disc. When the grating disc rotates with the rotating end, the light-transmitting stripes on the disc periodically block the light source. The photoelectric device receives the on-off change of the light signal and converts it into a pulse signal. By calculating the number of pulses per unit time, the rotational speed of the wheel body 92 can be accurately perceived. Since the wheel body 92 is always in close contact with the optical fiber assembly and moves synchronously, the rotational speed of the wheel body 92 detected by the encoder 94 can indirectly reflect the pulling speed of the optical fiber assembly.

[0054] If the pulling speed of the optical fiber assembly fluctuates, the encoder 94 will convert the speed change into a frequency change of the pulse signal and transmit it to the PLC controller 10 in real time. According to the preset standard speed parameter, the PLC controller 10 quickly responds to the adjustment. When the pulling speed is too fast, the PLC controller 10 automatically adjusts the rotational speed of the motor 61. When the pulling speed increases, the rotational speed of the motor 61 increases accordingly, so that the rotational speed of the rotating frame 4 driven by the pay-off stand 5 matches the moving speed of the optical fiber assembly. When the pulling speed slows down, the rotational speed of the motor 61 decreases accordingly, avoiding the steel wire from being wound too tightly or too loosely due to excessive rotation. Through the coordinated adjustment of the pulling speed and the rotational speed, the steel wire is always wound on the outer wall of the optical fiber assembly at a stable interval, maintaining the consistency of the production process.

[0055] After the steel wire is wound on the optical fiber assembly, the traction device sends the steel wire-wound optical fiber assembly into the head mold of the extruder. The molten material in the mold is wrapped around the outer part of the composite structure of the optical fiber assembly under the action of pressure, forming a protective sheath of a predetermined thickness, and completing the production of the composite optical fiber.

[0056] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
