Description

In optical fiber manufacturing, winding is a necessary step to collect and store the continuously drawn and coated finished optical fiber from the production line.

[0048] This invention provides a fiber-drawing device through improvements, such as Figures 1-12 As shown, including;

[0049] 100 fiber drawing machines;

[0050] The winding mechanism 200 includes a winding reel 210 rotatably mounted on the fiber drawing equipment 100, and a plurality of positioning components 220 slidably mounted on the winding reel 210;

[0051] The positioning component 220 includes a fixed clamping arm 221 and a telescopic clamping arm 222. Both the fixed clamping arm 221 and the telescopic clamping arm 222 are rotatably equipped with clamping members 223. The clamping members 223 include a first fitting part 2231 and a second fitting part 2232. The first fitting parts 2231 on both sides are used to limit the two sides of the flange drum, and the second fitting parts 2232 on both sides are used to limit the two sides of the bare roller drum.

[0052] The innovation of this equipment lies in the winding mechanism 200, which can automatically adjust its clamping shape according to different types and specifications of reels, achieving efficient and stable winding. The fiber drawing device 100 is the main body and power source of the device. It is responsible for providing power, which may include the traction force to pull the optical fiber forward and the rotational power to drive the winding mechanism 200. Multiple positioning components 220 are key actuators; they are slidably mounted on the winding reel 210 and can move closer to or further away from the center in the radial direction of the winding reel 210.

[0053] The fixed clamping arm 221 is slidably mounted on the take-up reel 210, and the telescopic clamping arm 222 can extend and retract relative to the fixed clamping arm 221. This allows for fine-tuning of the clamping arm length to accommodate reels of different widths. The clamping member 223 is the component that directly contacts both sides of the reel. It is rotatably mounted on the fixed clamping arm 221 and the telescopic clamping arm 222, and this rotatable mounting allows it to adjust its posture according to the reel's specifications for optimal fit.

[0054] The clamping member 223 integrates two different functional contact surfaces. When winding the flange drum, in the initial state, multiple positioning components 220 retract inwards, fitting the flange drum body onto them. Then, the linkage member 224 simultaneously pulls multiple linkage plates 2227 outwards. Multiple telescopic clamping arms 222 are pulled, and the clamping member 223 is flipped, causing the first contact portions 2231 on the inner and outer clamping members 223 to clamp the flange drum on both sides. Finally, the power source 217 is activated, at which point the multiple positioning components 220 expand outwards and press against the drum body.

[0055] During the winding of the roller reel, in the initial state, multiple positioning components 220 retract inward, fitting the roller reel body onto them. Then, multiple linkage plates 2227 are simultaneously pulled outward via linkage 224. Multiple telescopic clamping arms 222 are pulled, without flipping the clamping members 223, causing the second contact portions 2232 on the inner and outer clamping members 223 to clamp the roller reel on both sides. Finally, the power source 217 is activated, at which point the multiple positioning components 220 expand outward and press against the roller body.

[0056] See appendix Figure 2 - Appendix Figure 4 A drive shaft 211 is provided on the side of the take-up reel 210 facing the fiber drawing equipment 100, and a power cavity 213 is provided inside the drive shaft 211; multiple positioning grooves 214 are provided inside the take-up reel 210, which are corresponding to multiple positioning components 220, and the multiple positioning grooves 214 are all connected to the power cavity 213; the fixed clamping arm 221 is slidably disposed in the positioning groove 214.

[0057] In this embodiment, the drive shaft 211 is a transmission component connecting the fiber drawing device 100 and the take-up reel 210. On one hand, it receives the rotational power output from the fiber drawing device 100, driving the take-up reel 210 to rotate as a whole, providing basic rotational kinetic energy for fiber winding. This is consistent with the function of the drive shaft 211 driving the material roll to rotate in common winding equipment. On the other hand, its internal power cavity 213 provides a hidden installation space for the drive component of the positioning assembly 220, avoiding problems such as fiber entanglement and dust accumulation caused by exposed power structure, while making the overall structure more compact.

[0058] In this embodiment: the power cavity 213 serves as the hub for power distribution. It can house various power components. Since it is connected to all positioning slides 214, it can distribute a single power source 217 to multiple positioning components 220. For example, the power components inside the power cavity 213 can synchronously drive all fixed clamping arms 221, thereby achieving synchronous operation of multiple positioning components 220, ensuring balanced force during clamping, and avoiding skewing of the drum due to the lag in the action of a single positioning component 220.

[0059] In this embodiment, the positioning groove 214 serves as a guide and limiting channel for the fixed clamping arm 221. The shape of the positioning groove 214 precisely matches the sliding end of the fixed clamping arm 221, restricting its movement to the length of the groove and preventing lateral displacement during clamping, thus ensuring accurate alignment of the clamping component 223 with the drum side. Simultaneously, the positioning groove 214 also provides support for the fixed clamping arm 221, dispersing the reaction force of the drum on the positioning component 220 during clamping, preventing deformation of the fixed clamping arm 221 and the telescopic clamping arm 222, and improving structural durability.

[0060] In this embodiment, the sliding characteristics of the fixed clamping arm 221 within the positioning groove 214 are key to adapting to different specifications of drums. When dealing with large-diameter flanged drums or long smooth roller drums, the fixed clamping arm 221 can slide outward along the positioning groove 214 to expand the clamping span. When dealing with small-specification drums, it retracts inward to reduce the clamping distance.

[0061] In this embodiment: when adapting the flange drum, the power component in the power chamber 213 is activated, outputting power to each positioning groove 214, pushing the fixed clamping arm 221 to slide along the groove to the distance matching the flange. Subsequently, the fixed clamping arm 221, in conjunction with the telescopic clamping arm 222, adjusts its length so that the first contact portion 2231 of the clamping member 223 is tightly against the end face of the flange. After clamping in place, the drive shaft 211 drives the take-up reel 210 and the flange drum to rotate at a uniform speed, completing the fiber winding. The power chamber 213 continuously provides stable power to ensure that the clamping force of the clamping arm remains unchanged, preventing the flange from loosening.

[0062] In this embodiment: when adapting the optical roller drum, the clamping member 223 switches to the second contacting part 2232 to contact the side surface of the optical roller drum to prevent the optical roller drum from moving axially.

[0063] See appendix Figure 2 - Appendix Figure 5 The winding reel 210 has a plurality of first slots 215 on its axial outer wall, which are provided in accordance with the plurality of positioning slides 214. In the corresponding positioning slides 214 and first slots 215, the first slots 215 are connected to the positioning slides 214.

[0064] The fixed clamping arm 221 includes a lifting block 2211 and a first clamping rod 2214. The lifting block 2211 is slidably disposed in the positioning groove 214, and the first clamping rod 2214 is fixedly connected to one side of the lifting block 2211 and passes through the first slot 215.

[0065] In this embodiment, the first slot 215 provides a channel for the first clamping rod 2214 to penetrate the axial outer wall of the take-up reel 210, allowing the force-bearing end of the fixed clamping arm 221, i.e., the lifting block 2211, and the actuating end, i.e., the first clamping rod 2214, to achieve internal and external linkage. On the other hand, it serves a precise guiding function; its slot shape is adapted to the first clamping rod 2214, restricting its movement to the extension direction of the positioning groove 214, preventing lateral deviation or wobbling during clamping. Furthermore, the first slot 215 structure reduces frictional resistance during the movement of the first clamping rod 2214, while also facilitating observation of the movement status of the positioning assembly 220, thus simplifying future maintenance.

[0066] In this embodiment, when the lifting block 2211 slides within the positioning groove 214, it can convert the power transmitted by the power chamber 213 into a linear displacement of the first clamping rod 2214. Its design, penetrating the first slot 215, allows the sliding motion of the lifting block 2211 to be converted into a clamping and releasing action on the drum. For example, when the lifting block 2211 slides outward along the positioning groove 214, it will cause the first clamping rod 2214 to simultaneously approach the drum. When sliding inward, it will cause the first clamping rod 2214 to retract, releasing the drum.

[0067] In this embodiment: when adapting to the flange drum, the lifting block 2211 moves the first clamping rod 2214 to the corresponding position, so that the first contact portion 2231 of the clamping member 223 aligns with the side of the flange and clamps and limits its position. When adapting to the optical roller drum, the sliding distance of the lifting block 2211 is adjusted similarly, and the second contact portion 2232 is switched to contact the surface of the optical roller to complete the limiting.

[0068] See appendix Figure 7 - Appendix Figure 8 and attached Figure 10 The first clamping rod 2214 has a telescopic cavity 2215 on its axial outer wall facing the telescopic clamping arm 222; the telescopic clamping arm 222 includes a second clamping rod 2221, and a telescopic rod 2222 is provided on the axial outer wall of the second clamping rod 2221 facing the first clamping rod 2214. The telescopic rod 2222 is slidably disposed in the telescopic cavity 2215; a second reset member 2224 is also provided in the telescopic cavity 2215, and the two ends of the second reset member 2224 are respectively connected to the telescopic rod 2222 and the telescopic cavity 2215.

[0069] In this embodiment, adaptive clamping of the distance between the two sides of the drum is achieved through the sliding engagement of the telescopic cavity 2215 and the telescopic rod 2222, combined with the elastic force of the second reset member 2224. The telescopic cavity 2215 provides a precise sliding track for the telescopic rod 2222, ensuring that it can only extend and retract along the axial direction of the first clamping rod 2214, thus guaranteeing the linearity and stability of the clamping action. The second clamping rod 2221 is the final mounting carrier of the clamping member 223 and directly contacts the drum.

[0070] In this embodiment: the telescopic rod 2222 slides within the telescopic cavity 2215, enabling the second clamping rod 2221 to extend or retract relative to the first clamping rod 2214, thereby changing the total length of the entire clamping arm. The second reset member 2224 provides preload force. The second reset member 2224 is a spring, which, in its natural state, pushes and pulls the telescopic rod 2222 inward, bringing the second clamping rod 2221 closer to the first clamping rod 2214, thus ensuring that the clamping members 223 on both sides tighten the drum.

[0071] See appendix Figure 6 - Appendix Figure 8 A power source 217 is provided inside the power chamber 213. An extrusion member 218 is provided at the output end of the power source 217. A first inclined surface 219 is provided on the outer wall of the extrusion member 218 facing the fixed clamping arm 221. A second inclined surface 2213 is provided on the outer wall of the lifting block 2211 facing the extrusion member 218. The extrusion member 218 drives multiple lifting blocks 2211 to slide along the positioning slide groove 214 through the first inclined surface 219.

[0072] In this embodiment: the design utilizes the principle of force decomposition of inclined planes to convert the unidirectional power output by power source 217 into the synchronous radial sliding of multiple lifting blocks 2211, thereby driving the positioning component 220 to complete the clamping action of different drums.

[0073] In this embodiment: the power source 217 serves as the core of the entire clamping action, providing a stable driving force for the extruder 218. It can be equipped with common power components such as electric actuators and hydraulic rods, and can output a continuous and controllable linear thrust. This not only meets the force required for clamping the drum, but also allows for control of the clamping tightness through stroke adjustment, adapting to the clamping force requirements of drums of different materials, and avoiding damage to the drum due to excessive force or loosening of the clamp due to insufficient force.

[0074] In this embodiment: the extrusion member 218 is a key transfer component for power transmission. It receives the thrust of the power source 217 to make linear motion, and through its own first inclined surface 219, it forms a close fit with the second inclined surface 2213 of multiple lifting blocks 2211 to achieve single power input and multi-directional power output, ensuring that all positioning components 220 can move synchronously.

[0075] In this embodiment, the first inclined surface 219 and the second inclined surface 2213 together constitute a force steering mechanism. The angle design of the inclined surfaces directly determines the force conversion efficiency. A reasonable inclination angle can save effort, reduce the load on the power source 217, and ensure the smooth sliding of the lifting block 2211. At the same time, when the two inclined surfaces slide in contact, the lubrication treatment of the contact surfaces can reduce friction loss and extend the service life of the components. The guiding effect of the inclined surfaces can also prevent the lifting block 2211 from jamming or deviating during sliding.

[0076] In this embodiment: as the extruder 218 moves, its first inclined surface 219 gradually comes into close contact with the second inclined surface 2213 on each lifting block 2211. At this time, the axial thrust of the extruder 218 is decomposed by the contact action of the two inclined surfaces, and part of the force is transmitted along the inclined surfaces and transformed into a radial force that pushes the lifting block 2211 to move.

[0077] See appendix Figure 6 - Appendix Figure 8 The positioning slide 214 is also provided with a first reset member 2212, and the two ends of the first reset member 2212 are respectively connected to the positioning slide 214 and the lifting block 2211.

[0078] In this embodiment: the first reset member 2212 can provide retraction force. When the thrust of the power source 217 is removed, the spring of the first reset member 2212 will recover from the compressed state, and the released elastic potential energy will become the force to push the lifting block 2211 to slide in the opposite direction. The first reset member 2212 will push the lifting block 2211 to slide back to its initial position along the positioning slide groove 214, thereby driving the entire fixed clamping arm 221 and telescopic clamping arm 222 assembly to retract inward and release the clamping of the drum.

[0079] See appendix Figure 8 - Appendix Figure 10 The first clamping rod 2214 includes a first storage portion 2217, and the clamping member 223 is rotatably disposed within the first storage portion 2217; the second clamping rod 2221 includes a second storage portion 2225, and the clamping member 223 is rotatably disposed within the second storage portion 2225; a first storage shaft 2218 is disposed within the first storage portion 2217, and a second storage shaft 2226 is disposed within the second storage portion 2225; the clamping member 223 also includes a flipping seat 2233, and the clamping member 223 is rotatably disposed within the first storage shaft 2218 and the second storage shaft 2226 via the flipping seat 2233.

[0080] In this embodiment, the design can adapt to different types of rolls and protect the rolls and winding materials. The first storage section 2217 and the second storage section 2225 not only serve as installation and accommodating spaces but also provide a flipping limit for the clamping member 223. Their internal contours can be designed according to the maximum flipping angle of the clamping member 223 to avoid excessive flipping that could cause the structure to jam or be damaged.

[0081] In this embodiment: the first storage shaft 2218 and the second storage shaft 2226 are equivalent to the pivot points of the clamping member 223 when it is flipped, providing stable rotational support for the flipping seat 2233, ensuring that the clamping member 223 always moves around the fixed axis when it is flipped, and avoiding misalignment caused by deviation.

[0082] In this embodiment: when positioning the flanged drum, the clamping member 223 adaptively flips via the flipping seat 2233 until the first contact portion 2231 of the clamping member 223 is fully in contact with both sides of the drum. The flipping angle is fixed, forming a stable clamping state and ensuring uniform force. After the flanged drum is wound up, the clamping member 223 rotates back to its initial angle around the first storage shaft 2218 and the second storage shaft 2226 via the flipping seat 2233, preparing for the next clamping.

[0083] See appendix Figure 8 - Appendix Figure 10 The clamping member 223 also includes a torsion spring 2234; in the fixed clamping arm 221 and the clamping member 223, the two ends of the torsion spring 2234 are respectively connected to the first storage shaft 2218 and the flipping seat 2233; in the telescopic clamping arm 222 and the clamping member 223, the two ends of the torsion spring 2234 are respectively connected to the second storage shaft 2226 and the flipping seat 2233.

[0084] In this embodiment, the torsion spring 2234 structure provides an active and continuous preload to the flip-out clamping member 223, which upgrades the entire clamping mechanism from passive adaptation to active contact, improving the stability of clamping and its adaptability to complex working conditions.

[0085] In this embodiment, the torsion spring 2234 applies a torsional force to the flipping seat 2233 in its natural state. This force pushes the clamping member 223 to rotate around its axis, ensuring that its first contact portion 2231 always has a tendency to actively contact the drum. During this process, the torsion spring 2234 is further torsionated, storing elastic potential energy and generating a rebound force proportional to the torsion angle. This rebound force is the clamping preload acting on the drum.

[0086] In this embodiment: when the roll is removed, the torsion spring 2234 releases the stored elastic potential energy, pushing the clamp 223 back to its preset initial position, in preparation for the next clamping.

[0087] See appendix Figure 3 Appendix Figure 6 and attached Figure 10 - Appendix Figure 11 The second clamping rod 2221 has a linkage plate 2227 on its radial outer wall opposite to the first clamping rod 2214. The linkage plate 2227 has a second slot 2228. The positioning assembly 220 also includes a linkage member 224, which includes multiple cantilever arms 2241 corresponding to the multiple linkage plates 2227. Each cantilever arm 2241 has an engagement part 2242 and a limiting part 2243. In the corresponding linkage plate 2227 and cantilever arm 2241, the engagement part 2242 is slidably disposed in the second slot 2228.

[0088] In this embodiment: the linkage plate 2227 serves as an extension of the second clamping rod 2221, transmitting the radial sliding motion of the telescopic clamping arm 222 to the linkage member 224. The second slot 2228 on it provides a precise sliding track for the engaging portion 2242 of the linkage member 224, and the second slot 2228 restricts the direction of movement of the engaging portion 2242, allowing it to slide only within the slot.

[0089] In this embodiment: During the installation of the drum, in the initial state, multiple positioning components 220 retract inward, fitting the drum body onto the positioning components 220. Then, multiple linkage plates 2227 are simultaneously pulled outward via the linkage 224. This pulls multiple telescopic clamping arms 222, thereby clamping the inner and outer clamping members 223 onto both sides of the drum body. Finally, the power source 217 is activated, at which point the multiple positioning components 220 expand outward and press against the drum body.

[0090] See appendix Figure 3 Appendix Figure 8 and attached Figure 10 A drive wheel 212 is mounted on the drive shaft 211, and the drive shaft 211 is connected to an external power device through the drive wheel 212. A protective cover 216 is also mounted on the winding reel 210, which is used to cover the power chamber 213. Multiple limiting grooves 2216 are spaced apart on the radial inner wall of the telescopic chamber 2215, and multiple limiting blocks 2223 are provided on the radial outer wall of the telescopic rod 2222, which are corresponding to the multiple limiting grooves 2216. In the corresponding limiting grooves 2216 and limiting blocks 2223, the limiting blocks 2223 are slidably disposed in the limiting grooves 2216.

[0091] In this embodiment, the drive wheel 212 serves as a power input interface, acting as a connecting bridge between the drive shaft 211 and external power equipment, such as a motor or reducer. Through transmission methods such as belts, chains, or gears, the rotational torque of the external power equipment is efficiently and stably transmitted to the drive shaft 211, thereby driving the entire winding reel 210 to rotate.

[0092] In this embodiment, the protective cover 216 functions to shield the power cavity 213 and its internal power source 217, extrusion component 218, and other precision and high-speed rotating components, preventing operators from accidentally coming into contact with them and getting injured, and also preventing foreign objects, such as fiber optic fragments and dust, from entering the power cavity 213 and affecting its normal operation.

[0093] In this embodiment, the limiting groove 2216 provides a precise sliding track for the limiting block 2223 on the telescopic rod 2222, ensuring that the telescopic rod 2222 can only perform linear telescopic movement along the axial direction of the telescopic cavity 2215, thus guaranteeing the linearity and stability of the telescopic action. The cooperation between the limiting block 2223 and the limiting groove 2216 effectively prevents circumferential rotation of the telescopic rod 2222 during telescopic movement, which is crucial for maintaining the correct posture of the clamping member 223.

[0094] In this embodiment, the length of the limiting groove 2216 can limit the maximum extension stroke of the telescopic rod 2222, preventing it from extending or retracting excessively, thus playing a mechanical limiting and protective role.
