Description

Technical Field

[0001] This utility model relates to the field of optical fiber thermal fusion drawing technology, specifically to a diameter control structure for optical fiber thermal fusion drawing. Background Technology

[0002] Fiber optic thermal fusion drawing technology is a key process in fiber optic manufacturing. The principle is to place a preform made of high-purity quartz glass and other materials, with the required fiber refractive index distribution structure already formed inside, in a high-temperature drawing furnace. The end of the preform is softened and melted by resistance heating, induction heating or laser heating. Then, using a traction device, the softened glass is drawn into fibers, i.e., optical fibers, at a constant speed.

[0003] This technology requires strict control of parameters such as temperature, drawing speed, and tension. Excessive temperature may cause excessive evaporation of the glass, affecting the quality of the optical fiber. Improper control of speed and tension may result in uneven optical fiber diameter or internal stress. By continuously optimizing these parameters, low-loss, high-strength, and high-capacity optical fibers can be manufactured.

[0004] Currently, in existing optical fiber drawing processes, there is a coupling effect between diameter fluctuations and winding tension changes. When the diameter control system adjusts the traction speed or furnace temperature, the instantaneous change in the optical fiber linear velocity will cause fluctuations in winding tension, resulting in uneven tension on the optical fiber during the winding process.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model embodiment provides a diameter control structure for optical fiber thermal fusion drawing, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the device includes a collection box 1, a yarn inlet 2 on one side of the collection box 1, a box door 3 on the collection box 1, an adjustment component 4 inside the collection box 1, an auxiliary component 5 inside the collection box 1, a variable speed motor 6 fixedly connected inside the collection box 1, a connecting belt 7 sleeved on the output shaft of the variable speed motor 6 through a pulley, and a take-up roller 8 fixedly connected to the inner wall of the connecting belt 7 through a pulley. The variable speed motor 6 and the take-up roller 8 form a rotating structure through the connecting belt 7, and the connecting belt 7 is located between the variable speed motor 6 and the take-up roller 8, which enhances the connection effect between the variable speed motor 6 and the connecting belt 7, so that the variable speed motor 6 can drive the take-up roller 8 to rotate by driving the connecting belt 7.

[0023] The auxiliary component 5 includes a bracket 501, which is fixed inside the collection box 1. A drive motor 502 is mounted on the bracket 501. A lead screw 503 is fixedly connected to the output end of the drive motor 502. A movable plate 504 is threadedly connected to the outer wall of the lead screw 503. The drive motor 502 and the movable plate 504 form a threaded movement structure through the lead screw 503 and the movable plate 504. The outer diameter of the lead screw 503 matches the inner diameter of the movable plate 504, and the outer wall of the lead screw 503 fits against the inner wall of the movable plate 504, which enhances the connection between the drive motor 502 and the lead screw 503. This allows the drive motor 502 to rotate within the movable plate 504 by driving the lead screw 503.

[0024] A guide rod 505 is slidably connected to the movable plate 504. The movable plate 504 and the bracket 501 form a sliding structure through the guide rod 505. The inner diameter of the movable plate 504 matches the outer diameter of the guide rod 505, and the outer wall of the guide rod 505 fits against the inner wall of the movable plate 504, which strengthens the connection between the movable plate 504 and the guide rod 505, so that the movable plate 504 can slide by relying on the guide rod 505.

[0025] A device frame 506 is fixedly connected to one side of the movable plate 504. An auxiliary roller 507 is rotatably connected to the bottom of the device frame 506. By starting the variable speed motor 6, the winding roller 8 can be driven to rotate by the connecting belt 7, and the winding roller 8 can wind up the optical fiber. The winding speed can be adjusted by the variable speed motor 6 so that it can be precisely adjusted when the drawing speed changes. In the production process, the drawing speed can be precisely adjusted, and the winding speed can be matched with the drawing speed to maintain tension and achieve diameter stability.

[0026] In addition, during the drawing process, the optical fiber will directly enter the inlet 2 and pass through the auxiliary roller 507 on the equipment frame 506 and be wound on the outer wall of the winding roller 8. At this time, during the winding process, the drive motor 502 can be started to drive the lead screw 503 to rotate in the moving plate 504, so that the moving plate 504 can slide along the outer wall of the guide rod 505, thereby allowing the moving plate 504 to drive the auxiliary roller 507 to transport the optical fiber back and forth, reducing the occurrence of uneven winding.

[0027] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the adjusting component 4 includes a threaded sleeve 401, which is fixed to one side of the collection box 1. A screw 402 is threadedly connected to the inside of the threaded sleeve 401. An adjusting disc 403 is fixedly connected to one end of the screw 402. The adjusting disc 403 forms a threaded adjusting structure with the threaded sleeve 401 through the screw 402. The outer diameter of the screw 402 matches the inner diameter of the threaded sleeve 401, and the outer wall of the screw 402 fits against the inner wall of the threaded sleeve 401, which strengthens the connection between the adjusting disc 403 and the screw 402. This allows the adjusting disc 403 to rotate within the threaded sleeve 401 by driving the screw 402.

[0028] The other end of the screw 402 is rotatably connected to a mounting plate 404. A groove 405 is provided on the mounting plate 404, and a slide rod 406 is slidably connected inside the groove 405. A side plate frame 407 is fixedly connected to one side of the mounting plate 404, and an adjusting roller 408 is fixedly connected to one side of the side plate frame 407. The mounting plate 404 and the slide rod 406 form a sliding structure through the groove 405, and the inner diameter of the groove 405 matches the outer diameter of the slide rod 406. Furthermore, the outer wall of the slide rod 406 is fitted against the inner wall of the groove 405, strengthening the connection between the mounting plate 404 and the slide rod 406. The mounting plate 404 can slide along the outer wall of the slide rod 406 via the slide groove 405. Furthermore, by rotating the adjusting disc 403, the adjusting disc 403 can drive the screw 402 to rotate, allowing the screw 402 to rotate within the threaded sleeve 401. This allows the screw 402 to push the mounting plate 404 to move, enabling the mounting plate 404 to slide along the outer wall of the slide rod 406 via the slide groove 405. Additionally, the adjusting roller 408 on the side plate frame 407 can push the optical fiber to adjust the winding tightness.

[0029] Working Principle: During use, the variable speed motor 6, connected by the belt 7, drives the take-up roller 8 to rotate, allowing it to wind the optical fiber. The variable speed motor 6 can adjust the winding speed, enabling precise adjustment when the drawing speed changes. During production, the winding speed matches the drawing speed to maintain tension and achieve diameter stability. Furthermore, during the drawing process, the optical fiber directly enters the inlet 2 and passes through the auxiliary roller 507 on the equipment frame 506, winding onto the outer wall of the take-up roller 8. During winding, the drive motor 502 can be activated to drive the lead screw 503 to rotate within the moving plate 504, allowing... The movable plate 504 can slide along the outer wall of the guide rod 505, thereby driving the auxiliary roller 507 to transport the optical fiber back and forth, reducing uneven winding. In addition, by rotating the adjusting plate 403, the adjusting plate 403 can drive the screw 402 to rotate, allowing the screw 402 to rotate within the threaded sleeve 401. The screw 402 can push the mounting plate 404 to move, allowing the mounting plate 404 to slide along the outer wall of the slide rod 406 using the slide groove 405. This allows the adjusting roller 408 on the side plate frame 407 to push the optical fiber to maintain constant optical fiber tension and thus maintain stable winding.
