Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable forming technology, and in particular to an optical cable guide wheel assembly for a cable forming machine. Background Technology
[0002] In recent years, cable line faults have become increasingly frequent, leading to greater emphasis on cable safety. As a result, some cables with embedded optical fibers have appeared on the market. During cabling, the optical fiber is twisted together with the conductor within the cable. During operation, the embedded optical fiber can detect cable vibration and temperature via optical signals. These cables are produced using cabling machines, which typically include a cradle, guide rollers, a stranding device, and a traction machine. During production, both the optical fiber reel with the wound optical fiber and the conductor reel with the wound conductor are rotated and mounted on the cradle. The optical fiber is output from the reel, extends through the guide rollers to the stranding device, and is twisted onto the conductor. After twisting, the conductor and optical fiber are connected to the traction machine, which pulls the optical fiber forward, slowly outputting it from the reel. The optical fiber causes the reel to rotate accordingly, releasing the cable. However, when the existing cabling machine stops, the optical fiber reel continues to rotate due to inertia. This can cause the cable to loosen and easily detach from the guide rollers. When the cabling machine restarts, the cable can easily become stuck at the end of the guide rollers, leading to cable damage. Utility Model Content
[0003] In order to solve the problem that optical cables in existing cable-forming machines are prone to detaching from the guide rollers, this utility model proposes a guide roller in which the optical cable is less likely to detach from the guide roller when the machine is stopped.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A fiber optic cable guide wheel assembly for a cable forming machine includes a cradle, a fiber optic cable reel, a fiber optic cable positioning component, a guide wheel, and a power mechanism. The fiber optic cable reel and the guide wheel are rotatably connected to the front side of the cradle. The fiber optic cable is wound on the fiber optic cable reel and moves forward through the guide wheel. The fiber optic cable positioning component is provided on both the inlet and outlet sides of the guide wheel. The fiber optic cable positioning component includes a positioning cylinder, a slider, and a rubber sheet. The positioning cylinder is fixedly connected to the cradle. The fiber optic cable passes through the positioning cylinder axially. A groove is radially provided on the side of the positioning cylinder away from the guide wheel. The slider is slidably connected in the groove and driven by the power mechanism. The rubber sheet is fixedly connected to the inner end of the slider, and the inner end of the rubber sheet is inclined in the direction of fiber optic cable movement.
[0006] With the above settings, when the cabling machine stops, the power mechanism can drive the rubber sheet through the slider. The rubber sheet squeezes the optical cable to prevent the optical cable from detaching from the guide wheel. In addition, when the cabling machine restarts, the rubber sheet can also provide damping in the early stage of startup, so that the optical cable will not loosen when it is twisted.
[0007] Furthermore, the guide wheel assembly also includes a connecting plate, and the positioning cylinder is fixedly connected to the front side of the cradle through the connecting plate, while the guide wheel is rotatably connected to the connecting plate.
[0008] Furthermore, the power mechanism includes a pull cable, an electric cylinder, and a fixing ring. The electric cylinder is positioned on the angle bisector between the optical cable inlet and outlet directions, with its output end facing the guide wheel. The fixing ring is positioned between the guide wheel and the electric cylinder and is fixedly connected to the connecting plate. Two pull cables are provided, with one end of each cable fixedly connected to the output end of the electric cylinder. One pull cable is connected to the slider of one optical cable positioning component via the fixing ring, and the other pull cable is connected to the slider of another optical cable positioning component via the fixing ring. The optical cable positioning component also includes a spring, which applies a force to the slider in the opposite direction to the optical cable.
[0009] With the above setup, the electric cylinder extends and retracts to drive the movement of the slider and the rubber sheet.
[0010] Furthermore, the optical cable positioning assembly also includes a first movable plate, a second movable plate, a third movable plate, a first connecting rod, and a second connecting rod. The first movable plate is fixedly connected to the outer end of the slider. The second movable plate is located on the side of the positioning cylinder near the electric cylinder and is fixedly connected to the first movable plate via the first connecting rod. The third movable plate is fixedly connected to the side of the second movable plate near the electric cylinder via the second connecting rod. The end of the pull wire away from the electric cylinder is connected to the third movable plate.
[0011] With the above setup, the pull wire is connected to the slider via the third moving plate, the second connecting rod, the second moving plate, the first connecting rod, and the first moving plate.
[0012] Furthermore, the optical cable positioning assembly also includes a fixing plate and a bushing. The fixing plate is disposed between the second moving plate and the third moving plate and is fixedly connected to the connecting plate. The bushing is fixedly connected to the fixing plate. The second connecting rod passes through the bushing and is slidably connected to the bushing. A spring compression is disposed between the second moving plate and the fixing plate.
[0013] The above settings improve the stability of the slider's movement and facilitate spring installation.
[0014] Furthermore, the inner diameter of the positioning cylinder is d, and the outer diameter of the optical cable is r, 2 <d / r<4。
[0015] Furthermore, the inner circumferences at both ends of the positioning cylinder are rounded.
[0016] The above settings prevent the optical cable from being worn when it comes into contact with the end of the positioning cylinder. Attached Figure Description

[0020] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.
[0021] like Figures 1 to 3 A cable forming machine optical cable guide wheel assembly includes a cradle 3, an optical cable reel 4, an optical cable positioning component, a guide wheel 5, and a power mechanism. The optical cable reel 4 and the guide wheel 5 are rotatably connected to the front side of the cradle 3. The optical cable 9 is wound on the optical cable reel 4 and moves forward through the guide wheel 5. The aforementioned optical cable positioning component is provided on both the inlet and outlet sides of the guide wheel 5. The optical cable positioning component includes a positioning cylinder 6, a slider 7, and a rubber sheet 8. The positioning cylinder 6 is fixedly connected to the cradle 3. The optical cable passes through the positioning cylinder 6 axially. A groove is radially provided on the side of the positioning cylinder 6 away from the guide wheel 5. The slider 7 is slidably connected in the groove and driven by the power mechanism. The rubber sheet 8 is fixedly connected to the inner end of the slider 7, and the inner end of the rubber sheet 8 is inclined in the direction of optical cable movement.
[0022] With the above settings, when the cabling machine stops, the power mechanism can drive the rubber sheet 8 through the slider 7. The rubber sheet 8 squeezes the optical cable to prevent the optical cable from separating from the guide wheel 5. In addition, when the cabling machine restarts, the rubber sheet 8 can also provide damping in the early stage of startup, so that the optical cable will not loosen when it is twisted.
[0023] Specifically, the structure of the cradle 3 can refer to existing cable forming machines. The optical cable to be stranded is wound on the optical cable reel 4, which is located near the edge of the cradle 3. The guide wheel 5 is positioned on the side of the optical cable reel 4 closest to the center of the cradle 3. The side of the guide wheel 5 closest to the optical cable reel 4 is the inlet side of the optical cable, and the direction in which the optical cable moves forward after leaving the guide wheel 5 is the outlet side of the guide wheel 5. In this application, the angle between the inlet and outlet directions of the optical cable is approximately 120°, that is, the guide wheel 5 deflects the optical cable by 60°. Two optical cable positioning components are provided, one on the inlet side of the guide wheel 5 and the other on the outlet side. The optical cable on the inlet side axially passes through the positioning cylinder 6 of the optical cable positioning component on the inlet side, and the optical cable on the outlet side axially passes through the positioning cylinder 6 of the optical cable positioning component on the outlet side. The slider 7 and the rubber sheet 8 are located on the side of the optical cable away from the guide wheel 5. Figure 1 and Figure 2 When the cabling machine is running, the inner end of the slider 7 retracts into the groove, and the optical cable does not contact the inner wall of the positioning cylinder 6 or the rubber sheet 8. The optical cable moves forward continuously as the cabling process begins, pulling the optical cable reel 4 to rotate and release the cable. The power mechanism is connected to the controller of the cabling machine. When the cabling machine stops running, the controller simultaneously sends a signal to the power mechanism, triggering its action. The power mechanism drives the slider 7 to move into the positioning cylinder 6, and the slider 7 drives the rubber sheet 8... Figure 3The rubber sheet 8 presses the optical cable tightly against the inner wall of the positioning cylinder 6. At this time, even if the optical cable reel 4 rotates under inertia, the optical cable between the optical cable positioning component on the inlet side and the optical cable reel 4 will loosen, but the optical cable between the two optical cable positioning components will not loosen, thus preventing the optical cable from separating from the guide wheel 5. When the cabling machine restarts, the rubber sheet 8 does not loosen the optical cable at first, ensuring that the optical cable on the outlet side of the guide wheel 5 is in a taut state. At this time, the rubber sheet 8 provides a damping effect. When cabling begins, the optical cable moves forward for 5 seconds after passing the rubber sheet 8. At this time, the optical cable between the optical cable reel 4 and the optical cable positioning component on the inlet side is re-taut. The controller sends a signal to the power mechanism, the power mechanism is activated, and the slider 7 is driven to move outward. The rubber sheet 8 loosens the optical cable to reduce the wear of the rubber sheet 8.
[0024] As one implementation, the guide wheel assembly also includes a connecting plate 10, with the positioning cylinder 6 fixedly connected to the front side of the cradle 3 via the connecting plate 10, and the guide wheel 5 rotatably connected to the connecting plate 10.
[0025] As one implementation, the power mechanism includes a pull cable 11, an electric cylinder 12, and a fixing ring 13. The electric cylinder 12 is located on the angle bisector 14 between the optical cable inlet and outlet directions, with its output end facing the guide wheel 5. The fixing ring 13 is located between the guide wheel 5 and the electric cylinder 12 and is fixedly connected to the connecting plate 10. Two pull cables 11 are provided, with one end of the pull cable 11 fixedly connected to the output end of the electric cylinder 12. One pull cable 11 is connected to the slider 7 of one optical cable positioning component via the fixing ring 13, and the other pull cable 11 is connected to the slider 7 of another optical cable positioning component via the fixing ring 13. The optical cable positioning component also includes a spring 15, which applies a force to the slider 7 in the opposite direction to the optical cable.
[0026] With the above settings, the electric cylinder 12 extends and retracts to drive the movement of the slider 7 and the rubber sheet 8.
[0027] Specifically, the inner diameter of the fixing ring 13 is approximately twice the outer diameter of the pull wire 11. After the two pull wires 11 pass through the fixing ring 13, the pull wires 11 will not wobble. The end of one pull wire 11 is perpendicular to the infeed direction and is connected to the slider 7 of the optical cable positioning assembly on the infeed side. The end of the other pull wire 11 is perpendicular to the outfeed direction and is connected to the slider 7 of the optical cable positioning assembly on the outfeed side. When the electric cylinder 12 shortens, the output end of the electric cylinder 12 pulls the pull wire 11 backward. The two pull wires 11 respectively pull the sliders 7 of the two optical cable positioning assemblies into the positioning cylinder 6. Figure 3 When the electric cylinder 12 extends, the pull cable 11 is released, and the slider 7 moves outward from the positioning cylinder 6 under the action of the spring 15, and the rubber sheet 8 separates from the optical cable.
[0028] As one implementation, the optical cable positioning assembly also includes a first movable plate 16, a second movable plate 17, a third movable plate 18, a first connecting rod 19, and a second connecting rod 20. The first movable plate 16 is fixedly connected to the outer end of the slider 7. The second movable plate 17 is disposed on the side of the positioning cylinder 6 near the electric cylinder 12 and is fixedly connected to the first movable plate 16 through the first connecting rod 19. The third movable plate 18 is fixedly connected to the side of the second movable plate 17 near the electric cylinder 12 through the second connecting rod 20. The end of the pull wire 11 away from the electric cylinder 12 is connected to the third movable plate 18.
[0029] With the above configuration, the pull wire 11 is connected to the slider 7 via the third moving plate 18, the second connecting rod 20, the second moving plate 17, the first connecting rod 19, and the first moving plate 16.
[0030] Specifically, the first moving plate 16, the second moving plate 17, and the third moving plate 18 are all parallel to the axis of the positioning cylinder 6. The first connecting rod 19 is vertically fixed between the first moving plate 16 and the second moving plate 17, and the second connecting rod 20 is vertically fixed between the third moving plate 18 and the second moving plate 17. Figure 2 When the cable-forming machine is running, when the second moving plate 17 abuts against the positioning cylinder 6, the first moving plate 16 disengages from the positioning cylinder 6, and the rubber sheet 8 disengages from the optical cable. Figure 3 When the cable forming machine stops, the first moving plate 16 abuts against the positioning cylinder 6, the second moving plate 17 disengages from the positioning cylinder 6, and the rubber sheet 8 presses the optical cable tightly against the inner wall of the positioning cylinder 6.
[0031] As one implementation, the optical cable positioning assembly also includes a fixing plate 21 and a bushing 22. The fixing plate 21 is disposed between the second moving plate 17 and the third moving plate 18 and is fixedly connected to the connecting plate 10. The bushing 22 is fixedly connected to the fixing plate 21. The second connecting rod 20 passes through the bushing 22 and is slidably connected to the bushing 22. The spring 15 is compressed and disposed between the second moving plate 17 and the fixing plate 21.
[0032] The above settings improve the stability of the slider 7's movement and facilitate the installation of the spring 15.
[0033] In this application, the fixed plate 21 is parallel to the third moving plate 18, and the bushing 22 penetrates the fixed plate 21 perpendicularly. When the second connecting rod 20 is slidably connected to the bushing 22, the shaking of the second connecting rod 20 can be reduced, thereby improving the movement stability of the slider 7. The extension and retraction direction of the spring 15 is perpendicular to the axis of the positioning cylinder 6. One end of the spring 15 is fixedly connected to the second moving plate 17, and the other end is fixedly connected to the fixed plate 21. When the electric cylinder 12 retracts, the second moving plate 17 moves closer to the fixed plate 21, and the spring 15 retracts. When the electric cylinder 12 extends, the spring 15 rebounds, and the slider 7 moves outward from the positioning cylinder 6.
[0034] As one implementation method, the inner diameter of the positioning cylinder 6 is d, and the outer diameter of the optical cable is r, 2 <d / r<4。
[0035] As one implementation method, the inner circumferences of both ends of the positioning cylinder 6 are provided with rounded corners 23.
[0036] The above settings prevent the optical cable from being worn when it comes into contact with the end of the positioning cylinder 6.
[0037] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
