Description

Technical Field

[0001] This utility model relates to the field of drawing device technology, specifically a drawing device for PMMA optical fiber production. Background Technology

[0002] PMMA (polymethyl methacrylate) optical fiber is widely used in modern optical communication, optical sensing, and lighting fields due to its excellent optical performance, good flexibility, and low cost. However, the fiber drawing process is crucial in the production of PMMA optical fiber, and its technical level directly affects the quality of the fiber and production efficiency.

[0003] Traditional PMMA fiber drawing equipment has revealed numerous problems in practical applications. Firstly, the clamping structure design is flawed. Early drawing devices struggled to precisely control the clamping force on the fiber. Either the clamping was too tight, causing scratches on the fiber surface and affecting its optical performance and mechanical strength; or the clamping was too loose, allowing the fiber to slip during drawing, compromising uniformity and resulting in uneven fiber thickness, severely impacting product quality. Secondly, the power transmission and adjustment systems are inadequate. Traditional devices suffer from unstable power output, making it difficult to provide constant tension according to different production needs. Furthermore, adjusting the drawing speed and tension is complex, requiring frequent manual intervention, which is not only inefficient but also prone to adjustment errors. Utility Model Content

[0022] 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.

[0023] Example

[0024] like Figure 1-3 As shown in the figure, an embodiment of this utility model proposes a drawing device for PMMA optical fiber production, including a mounting base 1: serving as the basic support structure of the entire device, it is L-shaped. It provides mounting positions for other components and is stably connected to components such as the fixing box 2 and the drive motor 9 through welding, bolting, or other methods, ensuring the overall stability of the device and bearing the weight of each component as well as the forces generated during the drawing process.

[0025] like Figure 1-3 As shown, the fixing box 2 is fixedly installed on the mounting base 1, providing installation space for the positioning block 3 and the fixing wheel 4. The positioning block 3 is fixed inside the fixing box 2 and is rotatably connected to the fixing wheel 4, allowing the fixing wheel 4 to rotate flexibly. The fixing wheel 4 is used to support and guide the optical fiber, and cooperates with the chuck 6 to restrict the movement path of the optical fiber, ensuring the stability of the optical fiber's position during the fiber drawing process.

[0026] like Figure 1-3 As shown, slider 5 engages and slides within fixed box 2, allowing it to move smoothly within the box. A retaining wheel 6 is rotatably connected to slider 5, its shape matching that of fixed wheel 4, and both are equipped with grooved rings for clamping the optical fiber. One end of threaded rod 7 is rotatably connected to slider 5, and the other end passes through the side wall of fixed box 2 and is threadedly connected to it. Rotating threaded rod 7 allows adjustment of slider 5's position within fixed box 2 via threaded transmission, thereby adjusting the distance between retaining wheel 6 and fixed wheel 4, and thus adjusting the optical fiber clamping force.

[0027] like Figure 1-3 As shown, the drive wheel 8 is fixedly mounted on the output end of the drive motor 9, which is mounted on the side wall of the mounting base 1. When the drive motor 9 is working, its output shaft drives the drive wheel 8 to rotate, providing power for optical fiber drawing and enabling the optical fiber to move within the device to complete the drawing operation.

[0028] like Figure 1-3As shown, the mounting base 1 has three slide rails 10, and the adjusting block 11 is slidably connected in the slide rails 10 to ensure that the adjusting block 11 can move along the direction of the slide rails 10. The adjusting screw 12 is rotatably connected to the adjusting block 11, passes through the mounting base 1, and is threadedly connected to the mounting base 1. When the adjusting screw 12 is rotated, the adjusting block 11 can move up and down in the slide rails 10 by means of thread transmission. The adjusting wheel 13 is rotatably connected to the adjusting block 11, of which two adjusting wheels 13 correspond to the shape of the power wheel 8 and are provided with grooved rings, which are installed on the upper part of the power wheel 8 to guide the optical fiber through and change the direction of movement of the optical fiber; the other adjusting wheel 13 has a different height, and by adjusting its position, the tension of the optical fiber can be adjusted to ensure the stability of the tension of the optical fiber during the drawing process and improve the quality of the optical fiber.

[0029] During PMMA fiber drawing, the starting end is passed sequentially through the grooved ring between the fixed wheel 4 and the retaining wheel 6, and then through two adjusting wheels 13 that correspond in shape to the power wheel 8 and are also equipped with grooved rings. At the same time, the drive motor 9 of the drawing device is connected to an external power source. After ensuring that the connections between the mechanical components are secure and after checking that everything is correct, the drive motor 9 is turned on.

[0030] The drive motor 9 starts, driving the power wheel 8 to rotate. The power wheel 8 moves the PMMA material through friction. During this movement, the threaded rod 7 is rotated. The threaded rod 7 is threadedly connected to the fixed box 2, thereby adjusting the position of the slider 5 in the fixed box 2. This adjusts the clamping force of the fixed wheel 4 and the clamping wheel 6 on the material, preventing slippage during the fiber drawing process. Additionally, the adjustable screw 12 can be rotated. The adjustable screw 12 is threadedly connected to the mounting base 1, allowing the adjusting block 11 to slide in the slide rail 10. This adjusts the position of the adjusting wheels 13 at different heights, thereby adjusting the tension of the PMMA material and ensuring the stability of the optical fiber during the fiber drawing process.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
