Description

Technical Field

[0001] This utility model relates to the field of optical cable manufacturing equipment technology, specifically to an optical cable armor stranding device with pneumatic cleaning function. Background Technology

[0002] With the rapid development of the IT industry, competition among optical cable manufacturers is becoming increasingly fierce. Effectively reducing costs and improving first-pass yield has become the primary task for manufacturers to compete and enhance their survival capabilities. In a central tube optical cable structure, the armor layer is an indispensable and crucial part for protecting communication lines. The stranding cage, as a cable-bearing device that strands the metallic or non-metallic armor layers of the optical cable, produces optical cables with excellent compressive strength and resistance to biological attack. Therefore, the stranding effect of the armor layer is one of the key factors affecting the quality of the optical cable package.

[0003] Currently, when using metal wire armor or non-metal wire armor, dust is generated during SZ stranding. This continuously accumulating dust can clog the tiny threading holes inside the stranding cage, affecting the stranding process and causing uneven cable core outer diameter, or even breakage of the metal or non-metal wires in the armor layer. Existing stranding equipment cleaning technologies primarily focus on cleaning the surface of the stranding components, such as using a cleaning disc to clean the surface of the components or using an air gun.

[0004] Further analysis of existing technologies reveals the following significant shortcomings: Existing stranding cleaning techniques primarily target the surface of stranded components, neglecting the cleaning of tiny holes in the stranding equipment. Dust falling during stranding and clogging these holes is a major factor affecting stranding; therefore, the cleaning of the wire-threading holes within the stranding cage urgently needs improvement. Furthermore, existing stranding equipment cleaning is mostly continuous and indiscriminate. This method not only increases production costs and wastes resources, but the continuous use of air guns or cleaning discs also poses a risk to the quality of the finished optical cable. Cleaning should be conducted under appropriate conditions. In addition, most existing technologies lack post-cleaning processing methods, often requiring centralized processing only after production is complete. This is not only time-consuming and labor-intensive but also severely impacts production efficiency. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide an optical cable armor stranding device with pneumatic cleaning function.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A fiber optic cable armor stranding device with pneumatic cleaning function includes:

[0008] A fiber optic cable armor stranding device with pneumatic cleaning function includes:

[0009] A wire threading frame is provided with a wire threading frame through hole and a plurality of armor layer wire threading holes. Each of the armor layer wire threading holes is circumferentially distributed around the wire threading frame through hole, and a light sensor is provided on the periphery of each of the armor layer wire threading holes.

[0010] A central tube is installed on the wire threading frame through the through hole of the wire threading frame. The central tube has a wire threading hole along its length. Several winches are rotatably connected to the central tube. Several winches have wire passing holes. The wire passing holes of the winches are arranged around the circumference of the central tube.

[0011] A high-pressure air gun assembly includes a dynamic high-pressure air gun and several static high-pressure air guns. A fixing frame is installed along the length of the central tube.

The static high-pressure air gun is correspondingly arranged on the side of each winch, and the spray direction of each static high-pressure air gun is towards the cable guide hole of the winch.

[0012] The vacuuming assembly includes a vacuum fan and a dust collection box. The vacuum fan is located below the winch with its air outlet facing the winch. The dust collection box is connected to the air outlet of the vacuum fan.

[0013] Furthermore, the optical sensor is an infrared through-beam sensor.

[0014] Furthermore, both the dynamic high-pressure air gun and each of the static high-pressure air guns are connected to an air source via air supply pipes.

[0021] Compared with existing technologies, the advantages of this invention are as follows: Intelligent automatic cleaning significantly reduces the time cost of manual inspection and cleaning; automated monitoring and timely cleaning of threading hole blockages prevents production interruptions caused by blockages, ensuring the continuity of the production process. The use of an air gun for pneumatic cleaning of the auger threading holes allows for deeper cleaning than traditional manual cleaning, effectively removing residual impurities and dust. The combination of a vacuum fan and a dust collection box quickly collects and centrally processes falling dust, preventing dust accumulation from affecting the operation of production equipment and maintaining stable and efficient production.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] See appendix Figures 1-4 As shown, this application discloses a pneumatic cleaning device for optical cable armor stranding, which solves the problems of easy clogging of the threading holes, untimely cleaning, and incomplete dust treatment in existing optical cable armor stranding devices, achieving intelligent automatic cleaning, improving production efficiency and product quality. It includes a threading frame 1, a central tube 2, a high-pressure air gun assembly, and a dust collection assembly. The threading frame 1 serves as the basic support structure of the device, with threading frame through holes and several armor layer threading holes 3. Each armor layer threading hole 3 is evenly distributed circumferentially around the threading frame through holes, and each armor layer threading hole 3 is equipped with a photosensitive sensor 4 on its circumference. Through optical principles, the dust accumulation inside the hole is monitored in real time to avoid clogging and affecting threading efficiency. Preferably, the photosensitive sensor 4 is an infrared through-beam sensor, including a transmitter and a receiver, which are respectively located on both sides of the armor layer threading hole 3. A high-precision infrared through-beam photosensitive sensor monitors the degree of clogging of the threading hole in real time. When dust accumulation causes the light transmittance to fall below a preset threshold, the system automatically starts the cleaning program according to a graded logic. The central tube 2 is mounted on the cable guide frame 1 through a through-hole. The central tube 2 has a central tube through-hole 5 along its length. The central tube fiber optic sleeve passes through the central tube through-hole 5 at the entrance of the cable guide frame 1. Several winches 6 are fitted onto the central tube 2, and the winches 6 can rotate freely around the central tube 2. Each winch 6 has a winch through-hole 7, and these holes are arranged circumferentially around the central tube 2. Metal or non-metal wires pass through the winch through-hole 7 and then through the winch 6. Multiple winches 6 are twisted together via a SZ twisting process to form an armor layer, which protects the optical cable inside the central tube 2.

[0031] The high-pressure air gun assembly includes a dynamic high-pressure air gun 8 and several static high-pressure air guns 9. A fixing frame 10 is installed along the length of the central tube 2. The fixing frame 10 extends from the through hole of the wire threading frame to the inner and outer sides of the wire threading frame 1. A turntable 11 is installed on the fixing frame 10 located on the outer side of the wire threading frame 1. The dynamic high-pressure air gun 8 is connected to the turntable 11. The dynamic high-pressure air gun 8 can adjust its position by rotating with the turntable 11. The spray direction of the dynamic high-pressure air gun 8 is always aligned with the wire threading hole 3 of the armor layer. The dynamic high-pressure air gun 8 can rotate along the circumference of the outer side of the wire threading frame 1 under the drive of the turntable 11, so as to sequentially aim at different wire threading holes 3 of the armor layer for air blowing and cleaning. Each static high-pressure air gun 9 is located on a fixed frame 10 inside the cable threading frame 1. The static high-pressure air gun 9 is correspondingly positioned to the side of each winch 6, with its spray direction facing the winch cable passage hole 7. The position of the static high-pressure air gun 9 on the fixed frame 10 is adapted to the position of the winch cable passage hole 7, so as to clean all the winch cable passage holes 7 during the rotation of the winch 6. An intelligent control system is also included, which is electrically connected to the light sensor 4, dynamic high-pressure air gun 8, static high-pressure air gun 9, and turntable 11. The system is configured to control the start and stop of the dynamic high-pressure air gun 8, static high-pressure air gun 9, and turntable 11 based on the detection signal from the light sensor 4. When the light occlusion rate detected by the light sensor 4 exceeds a preset threshold, the intelligent control system triggers the dynamic high-pressure air gun 8 and static high-pressure air gun 9 to start and controls the turntable 11 to rotate. When the light sensor 4 detects no dust accumulation in the armor layer cable threading hole 3, it triggers the turntable 11 to stop rotating, and the dynamic high-pressure air gun 8 and static high-pressure air gun 9 to stop working. The intelligent control system can also adjust parameters such as pulse frequency and pulse pressure of the dynamic high-pressure air gun 8 and the static high-pressure air gun 9 according to the actual production situation, so as to realize intelligent control.

[0032] The dust collection assembly includes a dust collection fan 12 and a dust collection box 13. The dust collection fan 12 is located below the winch 6, with its air outlet facing the winch 6. The dust collection box 13 is connected to the air outlet of the dust collection fan 12 and is used to draw the blown dust into the dust collection box 13 for centralized processing.

[0033] Preferably, the intelligent control system of this embodiment further includes a signal acquisition module, a threshold comparison module, and a pulse control module. The signal acquisition module is electrically connected to the light sensor 4 and is used to acquire light transmittance signals in real time; the threshold comparison module pre-stores a first blockage threshold and a second blockage threshold and is configured to compare the real-time light transmittance with the preset thresholds; the pulse control module is electrically connected to the dynamic high-pressure air gun 8 and the static high-pressure air gun 9 and is configured to generate pulse jet commands based on the comparison results. When the light sensor 4 detects that the light transmittance in the wire hole is lower than the first blockage threshold, the intelligent control system controls the corresponding dynamic high-pressure air gun 8 and static high-pressure air gun 9 to start and perform pulse jet cleaning; when the light transmittance detected by multiple light sensors 4 is lower than the second blockage threshold, the intelligent control system controls all dynamic high-pressure air guns 8 and static high-pressure air guns 9 to start synchronously and perform comprehensive cleaning.

[0034] Preferably, in this embodiment, both the dynamic high-pressure air gun 8 and each static high-pressure air gun 9 are connected to an air source via an air supply pipe 14. The air supply pipe 14 includes a main air pipe and branch air pipes, and each branch air pipe is equipped with a solenoid valve, which is electrically connected to the intelligent control system. The intelligent control system controls the opening and closing frequency of the solenoid valves to achieve pulsed air supply to the dynamic high-pressure air gun 8 and the static high-pressure air gun 9, thereby precisely controlling the jet pressure and duration.

[0035] Preferably, the suction port of the vacuum fan 12 in this embodiment is provided with a detachable filter screen. The pore size of the filter screen is configured to intercept dust particles with a diameter greater than 50 micrometers, so as to prevent large dust particles from entering the vacuum fan 12 and damaging the equipment.

[0036] Preferably, the dust collection box 13 in this embodiment is equipped with a dust concentration sensor and a full-level alarm device. The full-level alarm device is configured to issue an alarm signal when the dust accumulation height in the dust collection box 13 reaches a preset value, reminding the operator to clean the dust collection box 13 in a timely manner. The inner wall of the dust collection box 13 is provided with an anti-stick coating, which is a Teflon coating, to prevent dust from adhering to the inner wall of the dust collection box 13. The bottom of the dust collection box 13 is provided with an inclined guide plate, and the lowest point of the guide plate is provided with a dust discharge port to facilitate the discharge and cleaning of dust.

[0037] Preferably, in this embodiment, the inner walls of the central tube wire hole 5, the armor layer wire hole 3, and the winch wire hole 7 are provided with a wear-resistant coating, and the material of the wear-resistant coating is at least one of titanium nitride, tungsten carbide, or polytetrafluoroethylene.

[0038] Preferably, the threading frame 1 and the winch 6 in this embodiment are made of aluminum alloy.

[0039] During the optical cable armor stranding process, metal or non-metal wires are stranded through the armor layer threading hole 3 and the winch threading hole 7. Simultaneously, dust gradually accumulates in these areas. The light sensor 4 continuously monitors the light transmittance within the central tube threading hole 5. When the light transmittance falls below a preset threshold, the intelligent control system activates the corresponding dynamic high-pressure air gun 8 and static high-pressure air gun 9 to perform pulse-jet cleaning of the armor layer threading hole 3 and the winch threading hole 7. The high-pressure gas emitted by the dynamic and static high-pressure air guns 8 and 9 blows the dust from these areas down, and the dust collection fan 12 draws the blown-down dust into the dust collection box 13 for centralized processing. A filter screen intercepts large dust particles, preventing them from entering the dust collection fan 12. When the dust in the dust collection box 13 accumulates to a certain height, a full-level alarm signal is activated, reminding the operator to clean it promptly. Operators can monitor the equipment's operating status in real time through a human-machine interface and manually adjust relevant parameters as needed. Simultaneously, the remote monitoring module can transmit equipment operating data to a remote control center for remote monitoring and control. The fault diagnosis system can promptly detect equipment anomalies and issue alarms, ensuring the safe and stable operation of the equipment.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
