Description

Technical Field

[0001] This invention relates to the field of optical fiber production technology, and in particular to an intelligent tensioning device for an optical fiber production line. Background Technology

[0002] The production process of optical fiber involves heating the fiber core, injection extrusion of the sheath material, and the sheath material being formed by the extrusion die and tightly wrapped around the heated fiber core, thus initially forming the optical fiber. Since the initially formed optical fiber is at a high temperature and not yet fully shaped, the production process also involves water cooling and air drying, diameter measurement, straightening, and finally, winding.

[0003] In fact, a tensioning device is installed before winding to prevent the optical fiber from falling off. The structure of this tensioning device is roughly as follows: Figure 1 As shown, optical fiber 1 is pulled from the front end of the production line to the tensioning device, wound three times each by the upper winding wheel 2 and the lower winding wheel 3, and then guided to the take-up device by the guide wheel 4. The lower winding wheel 3 is fixed on the swing arm 5, and a pressure sensor 6 is installed at one end of the swing arm 5. If the optical fiber 1 on the upper winding wheel 2 and the lower winding wheel 3 is loose, the pressure sensor 6 detects that the pressure is too low, and the swing arm 5 swings down to tension the optical fiber 1 on the upper winding wheel 2 and the lower winding wheel 3. If the optical fiber 1 on the upper winding wheel 2 and the lower winding wheel 3 is too tight, the pressure sensor 6 detects that the pressure is too high, and the swing arm 5 swings up to loosen the optical fiber 1 on the upper winding wheel 2 and the lower winding wheel 3. The entire adjustment process is participated in by the pressure sensor 6, so that the detected pressure value is always maintained within a set range.

[0004] However, since the fiber 1 is wound three times on both the upper winding wheel 2 and the lower winding wheel 3, if the fiber 1 becomes loose, it will be the outermost or innermost winding that loosens first. Then, the different windings of fiber 1 will slide relative to each other on the lower winding wheel 3 until they reach equilibrium, and only then will the pressure sensor 6 detect it. Therefore, the traditional tensioning device has certain problems: when the fiber 1 becomes loose or too tight, the different windings of fiber 1 will slide relative to each other on the lower winding wheel 3, posing a risk of falling off. Furthermore, the detection by the pressure sensor 6 has a certain lag, and the adjustment effect is not optimal. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problems by providing an intelligent tensioning device for an optical fiber production line.

[0006] The technical solution of the present invention is an intelligent tensioning device for an optical fiber production line, comprising a frame, a crossbar at the top of the frame, an adjustment box near the bottom of the frame, an upper winding wheel and a guide wheel at both ends of the crossbar, a swing arm on the adjustment box, and a lower winding wheel at the end of the swing arm. The lower winding wheel includes an outer winding wheel, a middle winding wheel, and an inner winding wheel arranged sequentially from the outside to the inside. The outer winding wheel and the middle winding wheel, as well as the middle winding wheel and the inner winding wheel, are connected by a sliding joint structure. The sliding joint structure includes a first bearing embedded in the outer winding wheel or the middle winding wheel, and a second bearing embedded in the inner winding wheel or the middle winding wheel. The first bearing has a first sliding member with a first through hole, and the second bearing has a second sliding member with a second through hole. The first sliding member and the second sliding member are slidably connected along the radial direction of the lower winding wheel. The outer winding wheel, the middle winding wheel, and the inner winding wheel are connected by spring members passing through each of the first through holes and each of the second through holes.

[0007] The outer, middle, and inner orbital wheels are respectively equipped with a first pressure sensor, a second pressure sensor, and a third pressure sensor in their grooves. The end of the swing arm is provided with a vertically oriented support rod, and a horizontally oriented support plate is provided on the support rod. The support plate is provided with a first driving member and a second driving member. The first driving member is connected to the outer side of the outer orbital wheel to drive the outer orbital wheel to generate radial displacement along the lower orbital wheel. The second driving member is connected to the inner side of the inner orbital wheel to drive the inner orbital wheel to generate radial displacement along the lower orbital wheel.

[0008] When the pressure value sensed by the first pressure sensor or the third pressure sensor is outside the set range, the first driving member and the second driving member adaptively drive the outer and inner rotating wheels to generate displacement until the pressure value sensed by the first pressure sensor or the third pressure sensor returns to the set range.

[0009] In one embodiment, the first slider includes a first protrusion, a second protrusion, and a third protrusion arranged sequentially. A first groove is provided between the first protrusion and the second protrusion, and between the second protrusion and the third protrusion. The first through hole is provided on the second protrusion.

[0010] The second slider includes two first sliders spaced apart, the two first sliders being slidably connected to the two first slide grooves respectively, and the second through hole being disposed between the two first sliders.

[0011] In one embodiment, a first connecting shaft is provided on the outer side of the outer circumferential wheel, and a first connecting member is provided at the end of the first driving member, with the first connecting shaft and the first connecting member being fixedly connected.

[0012] In one embodiment, a second connecting shaft is provided on the inner side of the inner circumferential wheel, and a second connecting member is provided at the end of the second driving member. The second connecting shaft and the second connecting member are fixedly connected.

[0013] In one implementation, both the first driving component and the second driving component are electric cylinders.

[0014] In one embodiment, the bottom of the frame is provided with a base plate.

[0015] In one embodiment, the adjustment box is provided with an adjustment device, which includes a damping sleeve coaxially connected to the swing arm. A rotating rod coaxially connected to the damping sleeve is rotatably connected to the damping sleeve. A balance bar is provided on the rotating rod. The balance bar is along the radial direction of the rotating rod. A first counterweight is provided at one end of the balance bar, and a second counterweight is provided at the other end of the balance bar. The second counterweight can be adjusted in position along the axial direction of the balance bar.

[0016] In one embodiment, a detection disc is provided at the end of the rotating rod, a mounting plate is provided on the damping sleeve, a mounting seat is provided on the mounting plate, the mounting seat is located above the rotating rod, and a detection switch is provided on the mounting seat. The detection switch is facing the detection disc and is used to detect the angular displacement of the detection disc.

[0017] In one embodiment, the mounting base and the mounting plate are detachably connected.

[0018] In one embodiment, the wires of the detection switch are fixed to one side of the mounting plate.

[0019] The advantages of this invention compared to existing technologies are that if the optical fiber becomes loose or too tight, it is the outermost or innermost coil that becomes loose or too tight first, because the outermost coil is connected to the previous workstation and the innermost coil is connected to the next workstation. If the first or third pressure sensor detects a decrease in pressure first, it controls the first or second driving component to drive the outermost winding wheel to move radially along the lower winding wheel, or to drive the innermost winding wheel to move radially along the lower winding wheel. This prevents the optical fiber on the middle winding wheel from becoming loose, i.e., prevents the coils of optical fiber from sliding relative to each other on the lower winding wheel. Furthermore, it is significantly faster than traditional tensioning devices, because traditional tensioning devices only detect the pressure sensor after the coils of optical fiber have slid relative to each other on the lower winding wheel. Because of the sliding joint structure, the winding wheels can still function normally even after displacement of the outer or inner winding wheel. Attached Figure Description

[0026] The above and other embodiments and advantages of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] In one implementation, such as Figure 2-4 As shown.

[0028] The intelligent tensioning device for the optical fiber production line provided in this embodiment includes a frame 7. A crossbar 8 is provided at the top of the frame 7, and an adjustment box 9 is provided near the bottom of the frame 7. An upper winding wheel 2 and a guide wheel 4 are respectively provided at both ends of the crossbar 8. A swing arm 5 is provided on the adjustment box 9, and a lower winding wheel 3 is provided at the end of the swing arm 5. The lower winding wheel 3 includes an outer winding wheel 10, a middle winding wheel 11, and an inner winding wheel 12 arranged sequentially from the outside to the inside. The outer winding wheel 10 and the middle winding wheel 11, as well as the middle winding wheel 11 and the inner winding wheel 12, are connected by sliding... The connecting structure 13 includes a first bearing 14 embedded in the outer revolute 10 or the middle revolute 11, and a second bearing 15 embedded in the inner revolute 12 or the middle revolute 11. The first bearing 14 has a first sliding member 17 with a first through hole 16, and the second bearing 15 has a second sliding member 19 with a second through hole 18. The first sliding member 17 and the second sliding member 19 are slidably connected along the radial direction of the lower revolute 3. The outer revolute 10, the middle revolute 11, and the inner revolute 12 are connected by a connecting structure 13. Spring members 20 are connected through each first through hole 16 and each second through hole 18; a first pressure sensor 22, a second pressure sensor 23, and a third pressure sensor 24 are respectively provided in the wheel groove 21 of the outer circumferential wheel 10, the middle circumferential wheel 11, and the inner circumferential wheel 12; a vertically oriented support rod 25 is provided at the end of the swing arm 5; a horizontally oriented support plate 26 is provided on the support rod 25; a first driving member 27 and a second driving member 28 are provided on the support plate 26; the first driving member 27 is connected to the outer side of the outer circumferential wheel 10 for driving the outer circumferential wheel 10. The inner wheel 10 is displaced radially along the lower wheel 3. The second drive member 28 is connected to the inner side of the inner wheel 12 to drive the inner wheel 12 to displace radially along the lower wheel 3. When the pressure value measured by the first pressure sensor 22 or the third pressure sensor 24 is not within the set range, the first drive member 27 and the second drive member 28 adaptively drive the outer wheel 10 and the inner wheel 12 to displace until the pressure value measured by the first pressure sensor 22 or the third pressure sensor 24 returns to the set range.

[0029] In this embodiment, the optical fiber 1 is wound three turns alternately on the upper winding wheel 2 and the lower winding wheel 3. The upper winding wheel 2 has four grooves 21, and the lower winding wheel 3 has three grooves 21. Unlike traditional tensioning devices, the lower winding wheel 3 is composed of a separate outer winding wheel 10, a middle winding wheel 11, and an inner winding wheel 12. The lower winding wheel 3 is not directly located at the end of the swing arm 5, but is instead located at the end of the swing arm 5 with a vertical support rod 25. A horizontal support plate 26 is mounted on the support rod 25, and a first driving member 27 and a second driving member 28 are mounted on the support plate 26. The first driving member 27 is connected to the outer side of the outer winding wheel 10, and the second driving member 28 is connected to the inner side of the inner winding wheel 12. Next, the pressure sensors are no longer located at one end of the swing arm 5, but are instead located in the grooves 21 of the outer winding wheel 10, the middle winding wheel 11, and the inner winding wheel 12, respectively, with a first pressure sensor 22, a second pressure sensor 23, and a third pressure sensor 24. As for the sliding structure 13, it includes a first bearing 14 embedded in the outer circumferential wheel 10 or the middle circumferential wheel 11, and a second bearing 15 embedded in the inner circumferential wheel 12 or the middle circumferential wheel 11. The first bearing 14 is provided with a first sliding member 17 with a first through hole 16, and the second bearing 15 is provided with a second sliding member 19 with a second through hole 18. The first sliding member 17 and the second sliding member 19 are slidably connected along the radial direction of the lower circumferential wheel 3. The outer circumferential wheel 10, the middle circumferential wheel 11, and the inner circumferential wheel 12 are connected by spring members 20 passing through each first through hole 16 and each second through hole 18.

[0030] Based on the aforementioned technical features, the principle of intelligent tensioning in this embodiment is that if the optical fiber 1 becomes loose or too tight, the outermost or innermost coil of the optical fiber 1 will loosen or become too tight first, because the outermost coil of the optical fiber 1 is connected to the previous station, and the innermost coil of the optical fiber 1 is connected to the next station. Taking loosening as an example, the first pressure sensor 22 or the third pressure sensor 24 will first detect a decrease in pressure. Then, the first driving component 27 or the second driving component 28 will be controlled accordingly to drive the outer winding wheel 10 to move radially along the lower winding wheel 3, or to drive the inner winding wheel 12 to move radially along the lower winding wheel 3. This prevents the optical fiber 1 on the middle winding wheel 11 from becoming loose, that is, prevents the coils of optical fiber 1 from sliding relative to each other on the lower winding wheel 3. Furthermore, it is significantly superior to traditional tensioning devices in terms of detection speed, because traditional tensioning devices only detect the pressure sensor 6 after the coils of optical fiber 1 have slid relative to each other on the lower winding wheel 3. Because of the sliding joint structure 13, each of the outer and inner rotating wheels can still be used normally after displacement of the outer rotating wheel 10 or the inner rotating wheel 12. It should be noted that the outer rotating wheel 10, the middle rotating wheel 11, and the inner rotating wheel 12 are connected by spring members 20 passing through each first through hole 16 and each second through hole 18. On the one hand, the spring 20 serves to fix the intermediate rotating wheel 11. On the other hand, when the outer rotating wheel 10 or the inner rotating wheel 12 is displaced, the spring 20 also causes the intermediate rotating wheel 11 to displace by a smaller amplitude than the outer rotating wheel 10 and the inner rotating wheel 12. This function has two aspects: if the optical fiber 1 on the outer rotating wheel 10 becomes loose, the intermediate rotating wheel 11 follows the movement of the outer rotating wheel 10, delaying the rapid transmission of the loosening of the optical fiber 1 to the inner rotating wheel 12. Similarly, if the optical fiber 1 on the outer rotating wheel 10 becomes too tight, the intermediate rotating wheel 11 follows the movement of the outer rotating wheel 10, delaying the rapid transmission of the excessive tightness of the optical fiber 1 to the inner rotating wheel 12.

A first through hole 16 is provided on the second protrusion 30. The second sliding member 19 includes two first sliding blocks 33 arranged at intervals. The two first sliding blocks 33 are slidably connected to the two first sliding grooves 32 respectively. A second through hole 18 is provided between the two first sliding blocks 33.

[0033] In this embodiment, a specific structure for the first slider 17 is provided, comprising a first protrusion 29, a second protrusion 30, and a third protrusion 31 arranged sequentially.

A specific structure for the second slider 19 is also provided, comprising two spaced-apart first sliders 33. When the first slider 17 and the second slider 19 are joined together, the two first sliders 33 are slidably connected to the two first grooves 32, thereby achieving radial displacement along the lower circumferential wheel 3.
