Description

Technical Field

[0001] This utility model relates to the technical field of fiber drawing devices, specifically to a fiber drawing device with constant tension speed. Background Technology

[0002] Optical fiber, short for optical waveguide fiber, is a type of fiber made of glass or plastic that can be used as a means of transmitting light. The transmission principle is "total internal reflection of light".

[0003] In the optical fiber manufacturing process, the fiber drawing process is an extremely critical step. During the drawing process, the stability of the tension on the optical fiber and the precise control of the drawing speed play a decisive role in the quality of the optical fiber. If the tension is unstable, it will lead to uneven fiber thickness, affecting its optical performance and mechanical strength; while fluctuations in the drawing speed may cause internal structural defects in the optical fiber, reducing its transmission performance.

[0004] Currently, some fiber drawing devices on the market have numerous shortcomings in controlling tension and speed. Some devices use simple mechanical counterweights to maintain tension, but this method makes it difficult to adjust the tension according to actual production conditions. Other devices rely on manual adjustment by operators based on feel, which is not only inefficient but also makes it difficult to achieve precise and stable speed control. This seriously affects the consistency and stability of fiber optic product quality and fails to meet the high-precision and high-efficiency requirements of modern fiber optic production. Therefore, a fiber drawing device with constant tension and speed is needed to solve the aforementioned problems. Utility Model Content

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a fiber drawing device with constant tension speed, which has the following advantages:

[0017] The lifting assembly is driven by a drive component to raise and lower the fiber optic cable. When the lifting assembly raises and lowers, it also raises and lowers the mounting frame and mounting slot. When the tension wheel moves downwards, the tension required for the fiber optic cable to press against the tension wheel during winding increases, simultaneously compressing the spring. When the tension wheel moves upwards, the tension required for the fiber optic cable to press against the tension wheel decreases, simultaneously compressing the spring. This reduces the spring's elasticity, thus adjusting the fiber optic cable tension. A tachometer can measure the speed at the center of the outer circumference of the tension wheel in real time. Since the rotation between the tension wheel and the fiber optic cable reflects the fiber optic cable speed, the winding speed of the winding mechanism can be adjusted based on the speed measured by the tachometer. This provides a constant tension speed fiber optic cable drawing device that allows for adjustment of tension according to actual production conditions. It eliminates the need for manual adjustment of the fiber optic cable speed by operators, thus improving the consistency and stability of fiber optic product quality and meeting the high precision and efficiency requirements of modern fiber optic production.

Detailed Implementation

[0023] 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.

[0024] Example

[0025] Please see Figures 1-4 A fiber constant tension speed drawing device includes a drawing tower 1, an optical fiber 2 and a first guide wheel 3. The optical fiber 2 is rotatably connected to the first guide wheel 3. The device also includes a first mounting plate 4 and two sets of second guide wheels 5. The first mounting plate 4 is installed on one side of the drawing tower 1, and the two sets of second guide wheels 5 are installed at the front end of the first mounting plate 4.

[0026] The tension adjustment assembly is located between the two sets of second guide wheels 5. The tension adjustment assembly includes a tension wheel 6, a mounting groove 7, a slide rod 8, a spring 9, two sets of first guide rods 10, a mounting frame 11, a lifting assembly, and a deceleration drive assembly. The lifting assembly is installed at the front end of the first mounting plate 4. The deceleration drive assembly is used to drive the lifting assembly to lift. The mounting frame 11 is installed at the bottom end of the lifting assembly. The two sets of first guide rods 10 are slidably connected to the mounting frame 11. A first through hole is provided through the bottom end of the mounting frame 11. The slide rod 8 is slidably connected to the first through hole. The bottom end of the slide rod 8 and the bottom end of the two sets of first guide rods 10 are both connected to the top end of the mounting groove 7. The spring 9 is fitted with the slide rod 8. The top end of the spring 9 is connected to the bottom end of the mounting frame 11. The bottom end of the spring 9 is connected to the top end of the mounting groove 7. The tension wheel 6 is rotatably connected to the mounting groove 7. The optical fiber 2 is rotatably connected to the two sets of second guide wheels 5 and the tension wheel 6.

[0027] The winding mechanism is used to wind up the optical fiber filament 2. A speed measuring instrument 25 is installed at the top of the inner side of the mounting slot 7. The lifting assembly is driven by the drive component to lift and lower. When the lifting assembly lifts and lowers, it can drive the mounting frame 11 to lift and lower, and at the same time drive the mounting slot 7 to lift and lower. When the tension wheel 6 moves downward, the tension required for the optical fiber filament 2 to squeeze the tension wheel 6 upward during winding needs to increase, and at the same time squeeze the spring 9. When the tension wheel 6 moves upward, the tension required for the optical fiber filament 2 to squeeze the tension wheel 6 upward during winding decreases, and at the same time squeeze the spring 9 decreases, so that the elastic force of the spring 9 decreases, thus achieving adjustment. The tension of the fiber filament 2 can be measured in real time by a speed measuring instrument 25, which measures the speed at the center of the outer circumference of the tensioning wheel 6. Since the rotation between the tensioning wheel 6 and the fiber filament 2 reflects the speed of the fiber filament 2, the winding speed of the winding mechanism can be adjusted based on the speed measured by the speed measuring instrument 25. Therefore, a constant tension speed fiber drawing device is provided, which can adjust the tension according to actual fiber production conditions and eliminates the need for operators to manually adjust the fiber filament speed based on feel. This improves the consistency and stability of fiber optic product quality and meets the high precision and high efficiency requirements of modern fiber optic production.

[0028] Please see Figures 1-4 The lifting assembly includes a second mounting plate 12, two sets of second guide rods 13, a lifting screw 14, and a rotating sleeve 15. The second mounting plate 12 is installed at the front end of the first mounting plate 4. A rotating hole is provided through the top of the second mounting plate 12. The rotating sleeve 15 is rotatably connected to the rotating hole. The screw is connected to the inner side wall of the rotating sleeve 15. The bottom end of the screw and the bottom end of the two sets of second guide rods 13 are connected to the top of the mounting frame 11. The two sets of second guide rods 13 are slidably connected to the second mounting plate 12. The rotation of the rotating sleeve 15 can drive the screw that cooperates with it to lift and lower, and at the same time drive the two sets of second guide rods 13 to lift and lower, thereby adjusting the tensioning speed.

[0029] Please see Figures 1-4 The reduction drive assembly includes a first motor 16, a drive shaft 17, a first bevel gear 18, and a second bevel gear 19. The first motor 16 is mounted on the second mounting plate 12. The drive shaft 17 is connected to the output end of the first motor 16. The first bevel gear 18 is connected to the drive shaft 17. The second bevel gear 19 is connected to the rotating sleeve 15. The first bevel gear 18 and the second bevel gear 19 are meshed. The diameter of the first bevel gear 18 is much smaller than the diameter of the second bevel gear 19. When the first motor 16 is powered on and started, it can drive the drive shaft 17 and the first bevel gear 18 to rotate, and at the same time drive the second bevel gear 19 to rotate, and at the same time drive the rotating sleeve 15 to rotate. Since the diameter of the first bevel gear 18 is much smaller than the diameter of the second bevel gear 19, the reduction function is achieved when driving the rotating sleeve 15 to rotate, making the lead screw lifting more stable and smooth.

[0030] Please see Figures 1-4 The winding mechanism includes a third mounting plate 20, a mounting frame 21, a winding shaft 22, and a second motor 23. The third mounting plate 20 is mounted on the front end of the first mounting plate 4, the mounting frame 21 is connected to the top end of the first mounting plate 4, the winding shaft 22 is rotatably connected to the mounting frame 21, the second motor 23 is mounted on the mounting frame 21, and the output end of the second motor 23 is connected to the input end of the winding shaft 22. The optical fiber filament 2 is wound on the winding shaft 22. Powering on and starting the second motor 23 can drive the winding shaft 22 to perform winding work. The speed of the optical fiber filament 2 can be measured in real time by a speed measuring instrument 25. Therefore, the winding speed of the winding shaft 22 can be adjusted according to the speed measured by the speed measuring instrument 25.

[0031] Please see Figures 1-4 A fixing plate 24 is provided at the top of the slide rod 8; the fixing plate 24 can prevent the slide rod 8 from sliding out of the first through hole.

[0032] In summary, when this constant tension speed fiber drawing device is in use, the lifting assembly is driven by the drive component to move up and down. When the lifting assembly moves up and down, it can drive the mounting frame 11 to move up and down, and at the same time drive the mounting groove 7 to move up and down. When the tension wheel 6 moves downward, the tension of the fiber filament 2 pressing upward on the tension wheel 6 during winding needs to increase, and at the same time, it squeezes the spring 9. When the tension wheel 6 moves upward, the tension of the fiber filament 2 pressing upward on the tension wheel 6 during winding decreases, and at the same time, the force squeezing the spring 9 decreases, so the elasticity of the spring 9 decreases. Therefore, the tension of the fiber filament 2 can be adjusted. The speed of the middle position of the outer circumference of the tension wheel 6 can be measured in real time by the speed measuring instrument 25. Since the rotation between the tension wheel 6 and the fiber filament 2 can reflect the speed of the fiber filament 2, the winding speed of the winding mechanism can be adjusted according to the speed measured by the speed measuring instrument 25.

[0033] The first motor 16, the second motor 23, and the speed measuring instrument 25 are commercially available devices known to those skilled in the art. We are simply using them here without making any structural or functional improvements, so we will not go into detail here. The first motor 16, the second motor 23, and the speed measuring instrument 25 are equipped with matching control switches. The installation position of the control switches is selected according to actual usage requirements to facilitate operation and control by the operator.

[0034] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
