[0002] Optical cables are communication transmission media composed of multiple optical fibers (glass or plastic fibers) combined with a specific protective structure. Their core structure includes the fiber core (transmitting optical signals), cladding (reflecting light waves), coating layer (mechanical protection), and outer sheath (tensile / compression / moisture-proof). Typical types, such as GYTA (stranded armored) and GYXTW (central loose tube), have the characteristics of large capacity (up to 100Tbps per fiber), low loss (0.2dB / km), and resistance to electromagnetic interference. They are widely used in telecommunications backbone networks, 5G base stations, submarine communications and other scenarios. Modern optical cables use color marks to distinguish the fiber serial numbers and use materials such as aramid yarn and steel tape to enhance mechanical properties.

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0020] Please refer to Figures 1-4 The coating machine includes a high-frequency machine 1, a steel wire 5 and an optical fiber 6.

[0021] The high-frequency machine 1, auxiliary wheel mechanism 2, coating machine 3, and air-cooling device 4 are arranged from left to right, with the entire production line 1000mm above the ground.

[0022] Specifically, the output end of the coating machine 3 is provided with a coating head 7, and the surface of the coating head 7 is respectively provided with a feed port 8 and a coating hole 9; The coating machine 3, with its optimized screw and new screw barrel design, speed regulation by a Jiale 4kW frequency converter, and a BJ122 gearbox, gives the extruder the following advantages; High plasticity, uniform melt, and continuous and stable production. High-performance gearbox reducers feature high torque, long service life, and low noise. The drive motor is an AC motor with frequency conversion control, and its center height is 1000mm. Screw diameter: 30mm; Length-to-diameter ratio: 30:1 Material: 38CrMoAl A Surface treatment: Nitriding, polishing Maximum speed: 96 r / min Barrel material: 38CrMoAl-A; Inner surface treatment: Nitriding, scouring Heating control zone: 3 zones; Heating method: ceramic heating coil with stainless steel fan cover.
