Description

Technical Field

[0001] This utility model relates to a release device for optical fiber winding, specifically to a fiber release device for winding optical fiber rings. Background Technology

[0002] Existing fiber optic winding devices typically consist of a main shaft, a moving disk, and a fiber supply module. The main shaft is the core component, responsible for driving the moving disk and the fiber supply module mounted on it to rotate. The moving disk acts as a bridge connecting the main shaft and the fiber supply module, ensuring synchronous movement between them. The fiber supply module usually consists of a feed wheel, a swing arm, and a tension wheel. Fiber optic cables are wound on the feed wheel. As the winding process progresses, the fiber optic cable is released from the feed wheel, and the tension wheel adjusts the tension on the cable before guiding it to the winding position. The swing arm is connected to the tension wheel, and its position is adjusted to regulate the fiber optic cable tension. When reversing direction, the fiber supply module on the moving disk disengages from the moving disk. Due to the change in the position of the feed module, the path of the fiber optic cable to the winding position also changes accordingly. The angle between the contact point between the fiber optic cable and the output end of the feed module changes. This change in angle causes localized stress when the fiber optic cable contacts this contact point, resulting in tension fluctuations that can damage the fiber optic cable or even cause it to break. Utility Model Content

[0003] The purpose of this invention is to provide a fiber release device for winding optical fiber rings, and the technical problem to be solved is how to reduce tension fluctuations during optical fiber release.

[0004] This utility model is achieved through the following technical solution:

[0005] A fiber feeding device for winding an optical fiber ring includes a fiber feeding assembly, a tension adjustment assembly, and a guide assembly, wherein the fiber feeding assembly and the guide assembly are respectively disposed on both sides of the tension adjustment assembly.

[0006] The aforementioned guide assembly includes a base, a guide wheel assembly, and a slider assembly. Each slider in the slider assembly includes a first driver and a telescopic shaft. One end of the telescopic shaft is connected to the output shaft of the first driver, and the other end of the telescopic shaft is connected to a slider.

[0007] The base is provided with a first through hole, and the telescopic shaft is used to pass through the first through hole and drive the telescopic shaft to move by the first driver; the base is provided with a limit shaft, and the slider is provided with a second through hole, and the limit shaft is used to pass through the second through hole;

[0008] The guide wheels in the guide wheel assembly and the sliders in the slider assembly are arranged in a one-to-one correspondence.

[0009] The aforementioned slider is provided with a first connecting shaft, and the guide wheel is sleeved on the first connecting shaft;

[0010] The axes of the guide wheels in the above-mentioned guide wheel group are parallel to each other, and there is a gap between adjacent guide wheels, which is used to pass through the optical fiber.

[0011] Because each of the aforementioned sliding components is equipped with a first driver and a telescopic shaft, the guide wheels can be dynamically adjusted according to the fiber's direction. When the fiber needs to be reversed, the corresponding sliding component can control the extension and retraction of the telescopic shaft through the first driver, thereby driving the slider to move along the limit shaft, and thus adjusting the position of the guide wheel. This dynamic adjustment can effectively reduce or eliminate the angular changes between the fiber extending from the guide wheel and the guide wheel during reversal, ensuring a smooth fiber transition. Each guide wheel has an independent drive system (i.e., a first driver), meaning that the position of each guide wheel can be controlled individually. During reversal, the position of the guide wheel can be adjusted individually according to the drive strategy, which helps maintain stable fiber tension and avoids fiber damage or performance degradation caused by tension changes. The gap design between the guide wheels in the guide wheel assembly allows the fiber to pass smoothly, while the parallel axes of the guide wheels ensure that the fiber maintains consistent directionality and straightness when passing through multiple guide wheels. By adjusting the position of each guide wheel to adapt to reversal requirements, friction and angular deviation between the fiber and the tooling are reduced. By reducing the angle change between the optical fiber extending from the guide wheel and the guide wheel, the lateral force on the optical fiber during commutation can be reduced, thereby reducing wear on the fiber surface and damage to the internal structure. This is very important for improving the quality of the optical fiber and extending its service life.

[0012] Furthermore, a first bearing is fitted onto the first connecting shaft, and a guide wheel is fitted onto the first bearing.

[0013] The aforementioned first bearing reduces the friction between the guide wheel and the first connecting shaft. When the guide wheel rotates, it does not generate additional resistance due to excessive friction, thus reducing the additional tension or pressure on the optical fiber. The presence of the first bearing makes the rotation of the guide wheel smoother, better maintaining the straightness and directionality of the optical fiber. During optical fiber reversal, the mobility and self-rotation of the guide wheel enable a rapid and accurate response to position changes, ensuring a smooth transition of the optical fiber.

[0014] Furthermore, the fiber feeding assembly includes a fiber feeding wheel, a second connecting shaft, and a second driver. One end of the second connecting shaft is connected to the output shaft of the second driver, and the other end of the second connecting shaft is connected to the fiber feeding wheel. The fiber feeding wheel is used for winding optical fibers.

[0015] The aforementioned second driver can control the rotational speed of the fiber feeding wheel, thereby ensuring a constant fiber speed during the feeding process. This helps maintain stable fiber tension throughout the winding process and avoids tension fluctuations caused by sudden speed changes. The second driver can work in conjunction with the first driver in the guiding assembly to adjust fiber tension and enable smooth fiber commutation by controlling the fiber feeding speed and the position of the guide wheel.

[0016] Furthermore, the aforementioned tension adjustment assembly includes a tension wheel, a swing element, a third connecting shaft, and a third driver, with one end of the third connecting shaft connected to the output shaft of the third driver;

[0017] The aforementioned swing component includes a swing arm and a connecting rod, with the connecting rod and the third connecting shaft vertically disposed at both ends of the swing arm;

[0018] The aforementioned connecting rod is fitted with a second bearing, and the aforementioned tension wheel is fitted with the second bearing;

[0019] The aforementioned tension wheel is used for winding the optical fiber that extends from the fiber feeding wheel. The optical fiber contacts the tension wheel surface furthest from the fiber feeding wheel, and the optical fiber extending from the tension wheel extends to the guide wheel.

[0020] The rotation of the third connecting shaft is controlled by the third driver, dynamically adjusting the position of the oscillating component, thereby changing the position of the tension wheel. This dynamic adjustment capability allows the tension wheel to adjust the tension in real time according to the actual needs of the optical fiber, ensuring that the tension of the optical fiber is always in an optimal state during the winding process. The L-shaped oscillating component allows the tension wheel to swing freely within a certain range, thus automatically adapting to changes in optical fiber tension. When the optical fiber tension changes, the oscillating component automatically adjusts its position to maintain tension stability. After the optical fiber extends from the fiber feeding wheel, it first passes through the tension wheel and then extends to the guide wheel. The function of the tension wheel is to pre-tension the optical fiber before it enters the guide wheel, ensuring that the tension of the optical fiber is in a relatively stable state when it enters the guide wheel. The oscillating component allows the tension wheel to be finely adjusted according to the actual tension of the optical fiber. When the position of the guide wheel changes, the tension on the optical fiber before entering the guide wheel also changes accordingly. Combined with the adjustment of the position of the tension wheel by the oscillating component, its tension is kept constant.

[0021] Furthermore, the fiber feeding device also includes an auxiliary component, which is disposed between the fiber feeding component and the guiding component;

[0022] The aforementioned auxiliary components include an auxiliary wheel, a fourth connecting shaft, a magnetic sensor, and a counter. The fourth connecting shaft is fitted with a third bearing, and the auxiliary wheel is fitted onto the third bearing.

[0023] The aforementioned magnetic sensor is located beside the auxiliary wheel, and a magnet is provided at one edge of the auxiliary wheel;

[0024] The aforementioned magnetic sensor and counter are connected. When the auxiliary wheel rotates, the magnetic sensor generates a pulse signal every time the magnet approaches it. The magnetic sensor is used to send the pulse signal to the counter, which records the number of pulse signals.

[0025] A magnet is placed on the aforementioned auxiliary wheel, and a magnetic sensor generates a pulse signal. Every time the auxiliary wheel rotates once, the magnet will approach the magnetic sensor once, generating a pulse signal. A counter records the number of pulse signals, thereby calculating the length of the optical fiber extension. The auxiliary wheel is connected to the fourth connecting shaft through a third bearing to ensure smoother rotation of the auxiliary wheel and reduce optical fiber jitter and offset caused by vibration.

[0026] Furthermore, the aforementioned auxiliary component is disposed between the fiber feeding component and the tension adjustment component. The aforementioned auxiliary wheel is used for winding the optical fiber extending from the fiber feeding wheel. The optical fiber contacts the auxiliary wheel surface furthest from the fiber feeding wheel, and the optical fiber extending from the auxiliary wheel extends to the tension wheel.

[0027] The aforementioned auxiliary wheel, acting as a tension assist component, provides tension conditions to the tension wheel. By winding around the auxiliary wheel, the stress on the optical fiber is dispersed, reducing stress concentration caused by the abrupt change from the fiber-laying wheel to the tension wheel, thus protecting the optical fiber from damage. The optical fiber undergoes initial tensioning via the auxiliary wheel before entering the tension wheel for tension adjustment; this gradual tensioning method improves the accuracy of controlling the optical fiber tension. As the fiber is continuously released during the rotation of the fiber-laying wheel, tension fluctuations occur during release, and these fluctuations also occur when adjusting the position of the tension wheel. The auxiliary wheel absorbs some of these tension fluctuations, reducing tension fluctuations caused by instantaneous changes in the fiber-laying wheel or tension wheel, and improving the tension stability of the fiber-laying device. The auxiliary wheel is connected to the fourth connecting shaft via a third bearing, ensuring smoother rotation and reducing fiber jitter and misalignment caused by vibration. The combination of a magnetic sensor and a counter monitors the length of the optical fiber, ensuring length control during release and avoiding tension changes due to length errors.

[0028] Furthermore, the aforementioned auxiliary component is disposed between the tension adjustment component and the guide component. The aforementioned auxiliary wheel is used for winding the optical fiber extending from the tension wheel. The optical fiber contacts the auxiliary wheel surface furthest from the tension wheel, and the optical fiber extending from the auxiliary wheel extends to the guide wheel.

[0029] The aforementioned auxiliary wheel not only provides tension conditions for the tension wheel but also provides guidance conditions for the guide wheel. Since the positions of both the guide wheel and the tension wheel are adjustable, this not only allows for a wider angle range when the optical fiber enters the guide wheel but also introduces tension fluctuations. The fixed position of the auxiliary wheel reduces tension fluctuations to some extent and narrows the angle range when the optical fiber enters the guide wheel, thus simplifying tension adjustment.

[0030] Furthermore, the aforementioned auxiliary components include at least two, wherein,

[0031] An auxiliary component is disposed between the fiber feeding component and the tension adjustment component. The auxiliary wheel of the auxiliary component is used for winding the optical fiber extending from the fiber feeding wheel. The optical fiber contacts the surface of the auxiliary wheel furthest from the fiber feeding wheel, and the optical fiber extending from the auxiliary wheel extends to the tension wheel.

[0032] An auxiliary component is disposed between the tension adjustment component and the guide component. The auxiliary wheel of the auxiliary component is used for winding an optical fiber extending from the tension wheel. The optical fiber contacts the auxiliary wheel surface furthest from the tension wheel, and the optical fiber extending from the auxiliary wheel extends to the guide wheel.

[0033] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0034] Because each of the aforementioned sliding components is equipped with a first driver and a telescopic shaft, the guide wheels can be dynamically adjusted according to the fiber's direction. When the fiber needs to be reversed, the corresponding sliding component can control the extension and retraction of the telescopic shaft through the first driver, thereby driving the slider to move along the limit shaft, and thus adjusting the position of the guide wheel. This dynamic adjustment can effectively reduce or eliminate the angular changes between the fiber extending from the guide wheel and the guide wheel during reversal, ensuring a smooth fiber transition. Each guide wheel has an independent drive system (i.e., a first driver), meaning that the position of each guide wheel can be controlled individually. During reversal, the position of the guide wheel can be adjusted individually according to the drive strategy, which helps maintain stable fiber tension and avoids fiber damage or performance degradation caused by tension changes. The gap design between the guide wheels in the guide wheel assembly allows the fiber to pass smoothly, while the parallel axes of the guide wheels ensure that the fiber maintains consistent directionality and straightness when passing through multiple guide wheels. By adjusting the position of each guide wheel to adapt to reversal requirements, friction and angular deviation between the fiber and the tooling are reduced. By reducing the angle change between the optical fiber extending from the guide wheel and the guide wheel, the lateral force on the optical fiber during commutation can be reduced, thereby reducing wear on the fiber surface and damage to the internal structure. This is very important for improving the quality of the optical fiber and extending its service life. Attached Figure Description

[0048] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0049] First embodiment:

[0050] like Figure 4 and Figure 6As shown, a fiber feeding device for winding an optical fiber ring includes a housing 5, on which a fiber feeding assembly 1, a tension adjusting assembly 2, and a guiding assembly 3 are disposed, with the fiber feeding assembly 1 and the guiding assembly 3 respectively disposed on both sides of the tension adjusting assembly 2.

[0051] The aforementioned guide assembly 3 includes a base 31, a set of guide wheels 32, and a set of sliders 34. The set of guide wheels 32 and the set of sliders 34 are disposed on the base 31, which is disposed on the upper surface of the housing 5. Each slider 34 in the set of sliders 34 includes a first driver 37 (which may be a hydraulic cylinder) and a telescopic shaft 36. One end of the telescopic shaft 36 is connected to the output shaft of the first driver 37, and the other end of the telescopic shaft 36 is connected to a slider 35.

[0052] The base 31 is provided with a first through hole 61, and the telescopic shaft 36 is used to pass through the first through hole 61 and is driven to move by the first driver 37; the base 31 is provided with a limit shaft 33, and the slider 35 is provided with a second through hole 62, and the limit shaft 33 is used to pass through the second through hole 62.

[0053] The aforementioned guide wheel 32 group consists of two guide wheels 32, and the slider 34 group consists of two sliders 34. The two guide wheels 32 are respectively mounted on the two sliders 34. The two sliders 34 are symmetrically arranged about the vertical plane of the base 31, and the sliders 35 are opposite to each other.

[0054] The aforementioned slider 35 is provided with a first connecting shaft 38, on which a first bearing 39 is sleeved, and a guide wheel 32 is sleeved on the first bearing 39. The first bearing 39 not only reduces the friction between the guide wheel 32 and the first connecting shaft 38, but also reduces the friction between the optical fiber and the guide wheel 32. When the optical fiber moves, it drives the guide wheel 32 to rotate. The optical fiber will not generate additional resistance due to excessive friction, thereby reducing the additional pulling or pressing force on the optical fiber.

[0055] The axes of the two guide wheels 32 are parallel to each other, and there is a gap between the guide wheels 32 for the optical fiber to pass through. The surface of the guide wheel 32 contacts the optical fiber.

[0056] Since each of the aforementioned sliding elements 34 is equipped with a first driver 37 and a telescopic shaft 36, the guide wheel 32 can be dynamically adjusted according to the direction of the optical fiber. When the optical fiber needs to be reversed, the corresponding sliding element 34 can control the extension and retraction of the telescopic shaft 36 through the first driver 37, thereby driving the slider 35 to move along the limiting shaft 33, and thus adjusting the position of the guide wheel 32. This dynamic adjustment can effectively reduce or eliminate the angle change between the optical fiber extending from the guide wheel 32 and the guide wheel 32 during reversal, reduce tension fluctuations when the optical fiber is released, and ensure a smooth transition of the optical fiber. Each guide wheel 32 has an independent drive system (i.e., the first driver 37), which means that the position of each guide wheel 32 can be controlled individually. During the reversal process, the position of the guide wheel 32 can be adjusted individually according to the drive strategy, which helps to maintain the stability of the optical fiber tension and avoid optical fiber damage or performance degradation caused by tension changes. The gap design between the guide wheels 32 in the guide wheel group 32 allows the optical fiber to pass smoothly. Simultaneously, the parallel axes of the guide wheels 32 ensure that the optical fiber maintains consistent directionality and straightness as it passes through multiple guide wheels 32. Adjusting the position of each guide wheel 32 adapts to commutation requirements, reducing friction and angular deviation between the optical fiber and the tooling. By reducing the angular change between the optical fiber extending from the guide wheel 32 and the guide wheel 32, the lateral force on the optical fiber during commutation can be reduced, thereby reducing wear on the fiber surface and damage to the internal structure. This is crucial for improving the quality of the optical fiber and extending its service life.

[0057] Specific implementation examples, such as Figure 2 As shown, the fiber feeding assembly 1 includes a fiber feeding wheel 11, a second connecting shaft 12, and a second driver 13 (which may be a stepper motor). One end of the second connecting shaft 12 is connected to the output shaft of the second driver 13, and the other end of the second connecting shaft 12 is connected to the fiber feeding wheel 11. The second driver 13 is disposed on the lower surface of the housing 5, and the second connecting shaft 12 passes through the housing 5 and extends to the upper surface of the housing 5. The fiber feeding wheel 11 is located on the upper surface of the housing 5. The fiber feeding wheel 11 is used for winding optical fibers.

[0058] The second driver 13 can control the rotational speed of the fiber feeding wheel 11, thereby ensuring a constant speed of the optical fiber during the feeding process. This helps maintain stable tension of the optical fiber throughout the winding process and avoids tension fluctuations caused by sudden speed changes. The second driver 13 can work in conjunction with the first driver 37 in the guide assembly 3 to adjust the optical fiber tension by controlling the feeding speed and the position of the guide wheel 32, thus enabling smooth optical fiber reversal.

[0059] Specific real-time, such as Figure 3As shown, the tension adjustment assembly 2 includes a tension wheel 21, a swing member 22, a third connecting shaft 23, and a third driver 24 (which may be a stepper motor). One end of the third connecting shaft 23 is connected to the output shaft of the third driver 24.

[0060] The aforementioned swing member 22 includes a swing rod 27 and a connecting rod 26, with the connecting rod 26 and the third connecting shaft 23 vertically disposed at both ends of the swing rod 27;

[0061] The connecting rod 26 is fitted with a second bearing 25, and the tension wheel 21 is fitted with the second bearing 25. The function of the second bearing 25 is similar to that of the first bearing 39. The third driver 24 is disposed on the lower surface of the housing 5. The third connecting shaft 23 passes through the lower surface of the housing 5 and extends to the upper surface of the housing 5. The swing member 22 passes through the upper surface of the housing 5. The connecting rod 26 passing through the upper surface of the housing 5 is fitted with a second bearing 25, and the tension wheel 21 is fitted with the second bearing 25.

[0062] The aforementioned tension wheel 21 is used for winding the optical fiber extending from the fiber feeding wheel 11, and the optical fiber contacts the surface of the tension wheel 21 furthest from the fiber feeding wheel 11 (e.g., Figure 1 As shown), the optical fiber extending from the tension wheel 21 extends to the guide wheel 32.

[0063] The rotation of the third connecting shaft 23 is controlled by the third driver 24, dynamically adjusting the position of the oscillating member 22, thereby changing the position of the tension wheel 21. This dynamic adjustment capability allows the tension wheel 21 to adjust the tension in real time according to the actual needs of the optical fiber, ensuring that the tension of the optical fiber is always in the optimal state during the winding process. The L-shaped oscillating member 22 allows the tension wheel 21 to swing freely within a certain range, thus automatically adapting to changes in the tension of the optical fiber. When the tension of the optical fiber changes, the oscillating member 22 will automatically adjust its position to maintain the stability of the tension. After the optical fiber extends from the fiber feeding wheel 11, it first passes through the tension wheel 21 and then extends to the guide wheel 32. The function of the tension wheel 21 is to pre-tension the optical fiber before it enters the guide wheel 32, ensuring that the tension of the optical fiber is in a relatively stable state when it enters the guide wheel 32. The oscillating member 22 allows the tension wheel 21 to be finely adjusted according to the actual tension of the optical fiber. When the position of the guide wheel 32 changes, the tension of the optical fiber before entering the guide wheel 32 also changes accordingly. Combined with the adjustment of the position of the tension wheel 21 by the oscillating member 22, the tension is kept constant.

[0064] Second embodiment:

[0065] Based on the first embodiment, the fiber feeding device further includes an auxiliary component 4, which is disposed between the fiber feeding component 1 and the guide component 3;

[0066] like Figure 5As shown, the auxiliary component 4 includes an auxiliary wheel 41, a fourth connecting shaft 42, a magnetic sensor (optional SS495A, MR200, CSD-1) and a counter (optional FX2N-10CT, CT310, CTR300). The fourth connecting shaft 42 is disposed on the upper surface of the housing 5, and a third bearing 43 is sleeved on the fourth connecting shaft 42. The auxiliary wheel 41 is sleeved on the third bearing 43.

[0067] The aforementioned magnetic sensor is disposed on the side of the auxiliary wheel 41, and a magnet 44 is disposed on one edge of the auxiliary wheel 41;

[0068] The magnetic sensor and the counter are connected. When the auxiliary wheel 41 rotates, the magnetic sensor generates a pulse signal every time the magnet 44 approaches the magnetic sensor. The magnetic sensor is used to send the pulse signal to the counter, and the counter records the number of pulse signals.

[0069] A magnet 44 is installed on the auxiliary wheel 41. A magnetic sensor generates a pulse signal. Each time the auxiliary wheel 41 rotates once, the magnet 44 will approach the magnetic sensor once, generating a pulse signal. A counter records the number of pulse signals to calculate the length of the extended optical fiber. The auxiliary wheel 41 is connected to the fourth connecting shaft 42 through the third bearing 43 to ensure smoother rotation of the auxiliary wheel 41 and reduce optical fiber jitter and offset caused by vibration. By monitoring the length of the optical fiber in real time, the rotation speed of the fiber feeding wheel 11, the position of the tension wheel 21 and the guide wheel 32 are adjusted in a timely manner to ensure that the tension of the optical fiber is constant during the extension process. Specifically, the counter, the first driver 37, the second driver 13 and the third driver 24 can be connected to the MCU. The MCU calls the existing adjustment strategy and issues instructions. The existing adjustment strategy is not described in detail.

[0070] Third embodiment:

[0071] Based on the second embodiment, such as Figure 7 As shown, the auxiliary component 4 is disposed between the fiber feeding component 1 and the tension adjustment component 2. The auxiliary wheel 41 is used for winding the optical fiber extending from the fiber feeding wheel 11. The optical fiber contacts the surface of the auxiliary wheel 41 furthest from the fiber feeding wheel 11, and the optical fiber extending from the auxiliary wheel 41 extends to the tension wheel 21.

[0072] The auxiliary wheel 41, as a tension assist element, provides tension conditions for the tension wheel 21. By winding the auxiliary wheel 41, the stress on the optical fiber is dispersed, reducing stress concentration caused by the abrupt change from the fiber-laying wheel 11 to the tension wheel 21, thus protecting the optical fiber from damage. The optical fiber is initially tensioned by the auxiliary wheel 41 before entering the tension wheel 21 for tension adjustment; this gradual tensioning method improves the accuracy of controlling the optical fiber tension. Since the optical fiber is continuously released as the fiber-laying wheel 11 rotates, tension fluctuations occur during the release process, and tension fluctuations also occur when adjusting the position of the tension wheel 21. The presence of the auxiliary wheel 41 can absorb some of these tension fluctuations, reducing tension fluctuations caused by instantaneous changes in the fiber-laying wheel 11 or the tension wheel 21, and improving the tension stability of the fiber-laying device. The auxiliary wheel 41 is connected to the fourth connecting shaft 42 via the third bearing 43, ensuring smoother rotation of the auxiliary wheel 41 and reducing optical fiber jitter and misalignment caused by vibration. The combination of a magnetic sensor and a counter can monitor the length of the optical fiber, ensuring length control during the release process and avoiding tension changes due to length errors.

[0073] Fourth embodiment:

[0074] Based on the second embodiment, such as Figure 8 As shown, the auxiliary component 4 is disposed between the tension adjustment component 2 and the guide component 3. The auxiliary wheel 41 is used for winding the optical fiber extending from the tension wheel 21. The optical fiber contacts the surface of the auxiliary wheel 41 furthest from the tension wheel 21, and the optical fiber extending from the auxiliary wheel 41 extends to the guide wheel 32.

[0075] The aforementioned auxiliary wheel 41 not only provides tension conditions for the tension wheel 21, but also provides guidance conditions for the guide wheel 32. Since the positions of both the guide wheel 32 and the tension wheel 21 are adjustable, not only is the angle range when the optical fiber enters the guide wheel 32 larger, but tension fluctuations also occur. The position of the auxiliary wheel 41 is fixed, which reduces tension fluctuations to a certain extent and also narrows the angle range when the optical fiber enters the guide wheel 32, reducing the difficulty of tension adjustment.

[0076] Fifth embodiment:

[0077] Based on the second embodiment, such as Figure 9 As shown, the aforementioned auxiliary component 4 has two parts, wherein,

[0078] An auxiliary component 4 is disposed between the fiber feeding component 1 and the tension adjustment component 2. The auxiliary wheel 41 of the auxiliary component 4 is used for winding the optical fiber extending from the fiber feeding wheel 11. The optical fiber contacts the surface of the auxiliary wheel 41 furthest from the fiber feeding wheel 11, and the optical fiber extending from the auxiliary wheel 41 extends to the tension wheel 21.

[0079] An auxiliary component 4 is disposed between the tension adjustment component 2 and the guide component 3. The auxiliary wheel 41 of the auxiliary component 4 is used for winding the optical fiber extending from the tension wheel 21. The optical fiber contacts the surface of the auxiliary wheel 41 furthest from the tension wheel 21, and the optical fiber extending from the auxiliary wheel 41 extends to the guide wheel 32.

[0080] Sixth embodiment:

[0081] Based on the second embodiment, such as Figure 1 and Figure 10 As shown, there are three auxiliary components 4 arranged in a triangle; for easy distinction, the three auxiliary components 4 are named Auxiliary Component 4-1, Auxiliary Component 4-2, and Auxiliary Component 4-3.

[0082] The aforementioned auxiliary component 4 is disposed between the fiber feeding component 1 and the tension adjustment component 2. The auxiliary wheel 41 of the auxiliary component 4 is used for winding the optical fiber extending from the fiber feeding wheel 11. The optical fiber contacts the surface of the auxiliary wheel 41 furthest from the fiber feeding wheel 11, and the optical fiber extending from the auxiliary wheel 41 extends to the tension wheel 21.

[0083] The aforementioned auxiliary component 42 is disposed between the tension adjustment component 2 and the guide component 3. The auxiliary wheel 41 of the auxiliary component 42 is used for winding the optical fiber extending from the tension wheel 21. The optical fiber contacts the surface of the auxiliary wheel 41 furthest from the tension wheel 21, and the optical fiber extending from the auxiliary wheel 41 extends to the auxiliary wheel 41 of the auxiliary component 43.
