Description

Technical Field

[0001] This utility model relates to the field of cable core processing technology, and more specifically, to a cable core straightening device. Background Technology

[0002] A cable is an electrical or signal transmission device, typically composed of several or groups of conductors, a cable core, an inner sheath in an optical cable and the portion therein, an inner stranded layer containing one or more optical units, a metal tube, or a skeleton core, etc. One step in cable processing is straightening, which facilitates subsequent processing and use.

[0003] Patent application number 202322347437.X discloses a cable conductive core wire straightening device, including a support platform. From left to right, the top surface of the support platform is arranged with a wire feeding frame, a first support, a pressing component, and a third support. A drive motor is fixedly mounted on the surface of the wire feeding frame, and a wire feeding roller is mounted on the output end of the drive motor. A cable is mounted on the wire feeding roller. A cleaning component is mounted on the first support. The pressing component consists of a second support, an upper roller, a lower roller, and a wire passage hole. In this invention, by setting up a cleaning component, the conductive core wire of the cable can be cleaned before straightening, preventing dust and dirt from damaging the surface of the core wire during the straightening process, ensuring the stability and aesthetics of the core wire during use. Furthermore, by setting pulleys inside the straightening component, the friction between the conductive core wire of the cable and the straightening component can be reduced, making straightening smoother and preventing the conductive core wire from being scratched.

[0004] Regarding the aforementioned technologies, this equipment, through the setting of the cleaning component, can clean the conductive core wires of the cable before straightening them. Subsequently, the straightening component straightens the cable. However, the equipment is equipped with a tension adjustment structure, which may cause the cable to loosen during the straightening and conveying process, thus affecting the subsequent straightening effect. Utility Model Content

[0005] To solve the above problems, this utility model provides a cable core straightening device, which adopts the following technical solution:

[0006] A cable core straightening device includes a base, a bracket at the bottom end of the base, a support plate fixedly mounted on one side of the base, an unwinding rod rotatably mounted on one side of the support plate, a winding roller slidably sleeved on the side wall of the unwinding rod, a plurality of positioning blocks arranged in a circular array fixedly mounted on the side wall of the unwinding rod, a positioning groove matching the positioning blocks being opened on the inner wall of the winding roller, a first reduction motor being provided on the side of the support plate away from the base, one end of the unwinding rod penetrating the support plate and fixedly connected to the end of the output shaft of the first reduction motor, and a sealing component being provided on the end of the unwinding rod away from the first reduction motor.

[0007] Two symmetrically distributed first support rods are fixedly installed on the support plate at the end away from the first geared motor. The side walls of the two first support rods are rotatably fitted with first support wheels. Two symmetrically distributed second support rods are fixedly installed on the support plate at the end away from the first geared motor. The side walls of the two second support rods are rotatably fitted with second support wheels. A first mounting plate is fixedly installed on the side of the support plate away from the first geared motor. A third mounting plate is fixedly installed on the top of the base. The first mounting plate is located between the two first support rods, and the third mounting plate is located between the two second support rods. Tension adjustment components are provided on the opposite sides of the first mounting plate and the third mounting plate.

[0008] A second mounting plate is fixedly installed on the top of the support plate. The second mounting plate has an inverted "L" shaped cross-section. A straightening assembly is provided below the second mounting plate. A support base is fixedly installed on the side of the support plate away from the first reduction motor. Two symmetrically distributed third mounting frames are slidably installed on the top of the support base. Multiple fifth support rods arranged in a linear array are fixedly installed in each of the two third mounting frames. Third straightening wheels are rotatably sleeved on the side walls of each fifth support rod. A drive assembly is provided between the two third mounting frames and the support base.

[0009] By adopting the above technical solution, when using the equipment, the operator slides the winding roller onto the side wall of the unwinding rod. The side wall of the unwinding rod is equipped with a positioning block. The positioning block engages with the positioning groove opened in the inner wall of the winding roller, which helps to maintain the stability of the winding roller installation. After the winding roller is placed, the unwinding rod end can be blocked by the sealing component, which can restrict and position the winding roller. Then, the operator passes one end of the cable core through the first support wheel, the second support wheel, the tension adjustment component, the straightening component and the two third straightening wheels in sequence, and then connects it with the existing traction structure. The cable core is pulled by the traction structure, and then the unwinding rod is driven by the first reduction motor to rotate the winding roller, which can unwind the cable core and facilitate the straightening of the cable core.

[0010] When the cable core is being transported, the tension of the cable core can be adjusted by the cooperation of two sets of tension adjustment components, the first support wheel, and the second support wheel. This helps to keep the cable core taut during transport, preventing it from becoming loose and maintaining the transport effect. In addition, the cooperation of the two sets of tension adjustment components, the first support wheel, and the second support wheel not only adjusts the tension of the cable core during transport but also initially straightens the cable core, which helps to improve the straightening effect of the equipment.

[0011] The cable core then passes between the straightening assembly and the two third straightening rollers. The cooperation between the straightening assembly and the third straightening rollers facilitates the straightening of different sides of the cable core, thus achieving the function of straightening the cable core. Furthermore, the distance between the two third straightening rollers can be adjusted by the drive assembly, which makes it easier for the equipment to straighten cable cores of different sizes, thereby improving the applicability of the equipment.

[0012] Furthermore, the sealing assembly includes a stop cap slidably sleeved on the side wall of the unwinding rod away from the first reduction motor. A stop ring is rotatably installed on the side of the stop cap near the first reduction motor. An installation groove is opened at the top of the base, and a transmission screw is rotatably installed in the installation groove. A support block is sleeved on the side wall of the transmission screw. A connecting rod is hinged to the top of the support block. The top of the connecting rod is fixedly connected to the side wall of the stop cap. A protective box is fixedly installed on the side of the base away from the support plate. The end of the transmission screw away from the support plate passes through the protective box. A worm gear is fixedly sleeved on the side wall of the end of the transmission screw passing through the protective box. A worm gear is rotatably installed in the protective box. The worm gear meshes with the worm wheel. A handle is fixedly installed at the top of the worm gear passing through the protective box.

[0013] By adopting the above technical solution, after the winding roller is placed, the operator rotates the connecting rod to align it with the unwinding rod, along with the stop cap and stop ring. Then, the operator drives the worm gear to rotate via the handle, which in turn drives the turbine to rotate. The turbine then drives the transmission screw to rotate, which in turn drives the support block to slide within the mounting groove. The support block, along with the connecting rod, stop cap, and stop ring, moves synchronously toward the unwinding rod, causing the stop cap to be fitted onto the side wall of the unwinding rod. This stabilizes the winding roller and helps maintain the stability of the rotation of the unwinding rod with the winding roller. Furthermore, the turbine and worm gear have self-locking properties, which helps maintain the stability of the connection between the stop cap and the unwinding rod.

[0014] Furthermore, the tension adjustment assembly includes a first cylinder fixedly installed on the top of the first mounting plate and the third mounting plate, wherein the piston shaft of one of the first cylinders slides through the first mounting plate, and a support column is fixedly installed at the end of each of the piston shafts of the two first cylinders. A movable groove is opened on the opposite side of each of the two support columns, and a support rod is slidably installed in each of the two movable grooves. A spring is fixedly connected between the opposite end of each of the two support rods and the inner wall of the opposite side of the movable groove on the same side. A first mounting frame is fixedly installed at the opposite end of each of the two support rods, and an adjustment wheel is rotatably installed in each of the two first mounting frames.

[0015] By adopting the above technical solution, the first cylinder drives the same-side support column, support rod, first mounting frame and adjusting wheel to move synchronously, thereby causing the adjusting wheel to push the cable core, so as to adjust the tension of the cable core during transportation. When the adjusting wheel pushes the cable core, the adjusting wheel pushes the same-side support rod to slide in the same-side movable groove, and the support rod pushes the same-side spring to contract. The spring gives the same-side support rod a rebound force, which can play a buffering role, helping to avoid the cable core from being damaged due to excessive tension, and achieving the effect of protecting the cable core.

[0016] Furthermore, two symmetrically distributed sliders are fixedly installed on the opposite sidewalls of the two support rods, and the inner walls of the two movable grooves are provided with grooves that match the sliders on the same side.

[0017] By adopting the above technical solution, when the support rod slides in the same side movable groove, the support rod slides in the same side sliding groove along with the slider. The cooperation between the slider and the sliding groove helps to maintain the stability of the support rod sliding and helps to prevent the support rod from leaving the same side movable groove.

[0018] Furthermore, the straightening assembly includes a second cylinder fixedly installed at the top of the horizontal section of the second mounting plate. The piston shaft of the second cylinder slides through the second mounting plate. A second mounting frame is fixedly installed at the end of the piston shaft of the second cylinder. Four third support rods arranged in a linear array are fixedly installed in the second mounting frame. The sidewalls of the third support rods are rotatably fitted with first straightening wheels. Four fourth support rods arranged in a linear array are fixedly installed on the side of the support plate away from the first reduction motor. The sidewalls of the fourth support rods are rotatably fitted with second straightening wheels. The fourth support rods are located below the second mounting frame.

[0019] By adopting the above technical solution, the second mounting frame, the third support rod and the first straightening wheel are driven to rise and fall synchronously by the second cylinder, which can adjust the distance between the first straightening wheel and the second straightening wheel, so that the equipment can straighten the cable cores of different sizes. The cable cores can be straightened by the squeezing of the first straightening wheel and the second straightening wheel.

[0020] Furthermore, the drive assembly includes a mounting box fixedly installed on the side of the support base away from the support plate. The mounting box contains a second reduction motor. The top of the support base has a moving slot. A double-threaded screw is rotatably installed in the moving slot. Moving blocks are sleeved on both side walls of the double-threaded screw. The tops of the two moving blocks are respectively fixedly connected to the bottom of the third mounting frame on the same side. The end of the double-threaded screw away from the support plate passes through the mounting box and is fixedly connected to the end of the output shaft of the second reduction motor.

[0021] By adopting the above technical solution, the double-toothed screw is driven to rotate by the second geared motor. The double-toothed screw drives two moving blocks to slide in the moving groove. The moving blocks carry the third mounting frame and the third straightening wheel on the same side, thereby achieving the effect of adjusting the distance between the two sets of third straightening wheels, which facilitates the equipment to straighten and straighten cable cores of different sizes.

[0022] Furthermore, two symmetrically distributed limiting blocks are fixedly installed at the bottom of each of the two third mounting frames, and the top of the support base is provided with a limiting groove that matches the limiting block on the same side.

[0023] By adopting the above technical solution, when the two third mounting frames slide above the support base, the third mounting frames, along with the limiting blocks, slide within the limiting grooves on the same side. The cooperation between the limiting blocks and the limiting grooves helps to maintain the stability of the sliding of the two third mounting frames.

[0024] Furthermore, a frame is fixedly installed on the side of the support plate away from the first reduction motor. The frame is located between the unwinding rod and the first support rod. Two staggered balance bars are rotatably installed inside the frame. A limit ring is fixedly installed in the middle of the inner wall at the bottom of the frame. Multiple balls arranged in a ring array are rotatably installed inside the limit ring.

[0025] By adopting the above technical solution, the workers pass one end of the cable core through the limiting ring, so that the cable core slides inside the limiting ring during transportation. The limiting ring can support and stabilize the cable core, and ensure stable transportation of the cable core. In addition, the inner wall of the limiting ring is equipped with rotating balls, which helps to reduce the friction when the cable core slides, thus achieving the effect of protecting the cable core.

[0026] In summary, this utility model has the following beneficial technical effects:

[0027] (1) In this utility model, by setting two sets of tension adjustment components, the tension of the cable core is adjusted during the transport, which helps to maintain the tightness of the cable core during transport. In addition, through the cooperation of the tension adjustment components, the first support wheel and the second support wheel, the cable core can be initially straightened.

[0028] (2) In this utility model, the cooperation of the first straightening wheel, the second straightening wheel and the third straightening wheel makes it easier for the equipment to straighten different sides of the cable core, which is beneficial to maintaining the uniformity of the straightening and improving the straightening efficiency of the equipment.

[0029] (3) In this utility model, the distance between the first straightening wheel, the second straightening wheel, and the two third straightening wheels can all be adjusted, which makes it easier for the equipment to transport and straighten cable cores of different sizes, and helps to improve the applicability of the equipment.

The inner wall of the winding roller 6 has positioning grooves matching the positioning blocks 34. A first reduction motor 36 is located on the side of the support plate 30 away from the base 1. One end of the unwinding rod 33 passes through the support plate 30 and is fixedly connected to the output shaft end of the first reduction motor 36. A sealing assembly is located on the end of the unwinding rod 33 away from the first reduction motor 36. The sealing assembly includes components slidably sleeved on the unwinding rod 33 away from the first reduction motor 36. A stop cap 4 is attached to one side wall.

[0045] When using the equipment, the operator slides the winding roller 6 onto the side wall of the unwinding rod 33. The side wall of the unwinding rod 33 is provided with a positioning block 34, which engages with the positioning groove opened on the inner wall of the winding roller 6 to help maintain the stability of the winding roller 6 installation. After the winding roller 6 is placed, the operator rotates the connecting rod 3 so that the connecting rod 3, along with the stop cap 4 and the stop ring 5, aligns with the unwinding rod 33. Then, the operator drives the worm gear 44 to rotate by using the handle. The worm gear 44 drives the turbine 43 to rotate, and the turbine 43 drives the transmission screw 37 to rotate. The transmission screw 37 drives the support block 38 to slide within the mounting groove 2. The support block 38, along with the connecting rod 3, the stop cap 4, and the stop ring 5, moves synchronously toward the unwinding rod 33, so that the stop cap 4 is fitted onto the side wall of the unwinding rod 33, which can stabilize the winding roller 6 and help maintain the stability of the rotation of the unwinding rod 33 with the winding roller 6. Furthermore, the worm gear 43 and the worm shaft 44 have self-locking properties, which helps maintain the stability of the connection between the stop cap 4 and the unwinding rod 33. The connecting rod 3 is hinged to the support block 38, which makes it easy for workers to disassemble and assemble the winding roller 6.

[0046] A frame 7 is fixedly installed on the side of the support plate 30 away from the first geared motor 36. The frame 7 is located between the unwinding rod 33 and the first support rod 8. Two staggered balance bars are rotatably installed inside the frame 7. A limit ring 35 is fixedly installed in the middle of the inner wall at the bottom of the frame 7. Multiple balls arranged in a ring array are rotatably installed inside the limit ring 35.

[0047] Two symmetrically distributed first support rods 8 are fixedly installed on the end of the support plate 30 away from the first geared motor 36. First support wheels 9 are rotatably sleeved on the sidewalls of the two first support rods 8. Two symmetrically distributed second support rods 14 are fixedly installed on the end of the support plate 30 away from the first geared motor 36. Second support wheels 17 are rotatably sleeved on the sidewalls of the two second support rods 14. A first mounting plate 12 is fixedly installed on the side of the support plate 30 away from the first geared motor 36. A third mounting plate 28 is fixedly installed on the top of the base 1. The first mounting plate 12 is located between the two first support rods 8, and the third mounting plate 28 is located between the two second support rods 14. The first mounting plate 12 and the third mounting plate 28 are... Tension adjustment components are provided on both sides. The tension adjustment components include first cylinders 13 fixedly installed on the top of the first mounting plate 12 and the third mounting plate 28. The piston shaft of one of the first cylinders 13 slides through the first mounting plate 12. Support columns 11 are fixedly installed at the ends of the piston shafts of the two first cylinders 13. Movable grooves 45 are opened on the opposite sides of the two support columns 11. Support rods 15 are slidably installed in the two movable grooves 45. Springs 46 are fixedly connected between the opposite ends of the two support rods 15 and the inner wall of the opposite side of the movable groove 45 on the same side. First mounting frames 10 are fixedly installed on the opposite ends of the two support rods 15. Adjusting wheels 16 are rotatably installed in the two first mounting frames 10.

[0048] After the winding roller 6 is placed, the worker passes one end of the cable core sequentially through the limiting ring 35, the first support wheel 9, the second support wheel 17, the adjusting wheel 16, the first straightening wheel 19, the second straightening wheel 23, and the two third straightening wheels 31 to facilitate subsequent cable core transport. When the cable core is transported, the first cylinder 13 drives the same-side support column 11, support rod 15, the first mounting frame 10, and the adjusting wheel 16 to move synchronously, thereby causing the adjusting wheel 16 to push the cable core, achieving the effect of adjusting the tension of the cable core during transport. When the adjusting wheel 16 pushes the cable core, the adjusting wheel 16 pushes the same-side support rod 15 to slide in the same-side movable groove 45, and the support rod 15 pushes the same-side spring 46 to contract. The spring 46 gives the same-side support rod 15 a rebound force, which can play a buffering role and help avoid damage to the cable core due to excessive tension, thus achieving the effect of protecting the cable core.

[0049] Two symmetrically distributed sliders are fixedly installed on the opposite side walls of the two support rods 15. The inner walls of the two movable grooves 45 are provided with sliding grooves that match the sliders on the same side. When the support rod 15 slides in the movable groove 45 on the same side, the support rod 15 slides in the sliding groove on the same side with the slider. The cooperation between the slider and the sliding groove helps to maintain the stability of the sliding of the support rod 15 and helps to prevent the support rod 15 from leaving the movable groove 45 on the same side.

[0050] A second mounting plate 21 is fixedly installed at the top of the support plate 30. The cross-section of the second mounting plate 21 is inverted "L" shape. A straightening assembly is provided below the second mounting plate 21. The straightening assembly includes a second cylinder 22 fixedly installed at the top of the horizontal section of the second mounting plate 21. The piston shaft of the second cylinder 22 slides through the second mounting plate 21. A second mounting frame 18 is fixedly installed at the end of the piston shaft of the second cylinder 22. Four third support rods 20 arranged in a linear array are fixedly installed in the second mounting frame 18. The side walls of the third support rods 20 are rotatably fitted with first straightening wheels 19. Four fourth support rods 24 arranged in a linear array are fixedly installed on the side of the support plate 30 away from the first reduction motor 36. The side walls of the fourth support rods 24 are rotatably fitted with second straightening wheels 23. The fourth support rods 24 are located below the second mounting frame 18.

[0051] The second cylinder 22 drives the second mounting frame 18, the third support rod 20 and the first straightening wheel 19 to rise and fall synchronously, which can adjust the distance between the first straightening wheel 19 and the second straightening wheel 23, making it easier for the equipment to straighten cable cores of different sizes. The compression of the first straightening wheel 19 and the second straightening wheel 23 can straighten the cable core.

[0052] A support base 26 is fixedly installed on the side of the support plate 30 away from the first geared motor 36. Two symmetrically distributed third mounting frames 25 are slidably mounted on the top of the support base 26. Multiple fifth support rods 32 arranged in a linear array are fixedly installed in each of the two third mounting frames 25. Third straightening wheels 31 are rotatably sleeved on the sidewalls of the fifth support rods 32. A drive assembly is provided between the two third mounting frames 25 and the support base 26. The drive assembly includes a mounting box 27 fixedly installed on the side of the support base 26 away from the support plate 30. A second geared motor 41 is installed in the mounting box 27. A moving groove 39 is opened on the top of the support base 26, and a second geared motor 41 is rotatably mounted in the moving groove 39. The device includes a double-threaded screw 40, with movable blocks 42 fitted on both sides of the screw 40. The tops of the two movable blocks 42 are fixedly connected to the bottom of the third mounting frame 25 on the same side. The end of the double-threaded screw 40 away from the support plate 30 passes through the mounting box 27 and is fixedly connected to the output shaft end of the second reduction motor 41. The second reduction motor 41 drives the double-threaded screw 40 to rotate, which in turn drives the two movable blocks 42 to slide within the movable groove 39. The movable blocks 42 carry the third mounting frame 25 and the third straightening wheel 31 on the same side, thereby adjusting the distance between the two sets of third straightening wheels 31. This facilitates the straightening and straightening of cable cores of different sizes by the device.

[0053] Two symmetrically distributed limiting blocks are fixedly installed at the bottom of each of the two third mounting frames 25. The top of the support base 26 is provided with a limiting groove that matches the limiting block on the same side. When the two third mounting frames 25 slide above the support base 26, the third mounting frames 25 slide with the limiting blocks in the limiting groove on the same side. The cooperation between the limiting blocks and the limiting groove helps to maintain the stability of the sliding of the two third mounting frames 25.

[0054] The implementation principle of this utility model embodiment is as follows: When using the equipment, the operator slides the winding roller 6 onto the side wall of the unwinding rod 33. The side wall of the unwinding rod 33 is provided with a positioning block 34. The positioning block 34 engages with the positioning groove opened in the inner wall of the winding roller 6, which helps to maintain the stability of the installation of the winding roller 6. After the winding roller 6 is placed, the end of the unwinding rod 33 can be blocked by the sealing component, which can restrict the positioning of the winding roller 6. Then, the operator passes one end of the cable core through the first support wheel 9, the second support wheel 17, the tension adjustment component, the straightening component and the two third straightening wheels 31 in sequence, and then connects it with the existing traction structure. The cable core is pulled by the traction structure, and then the unwinding rod 33 is driven by the first reduction motor 36 to rotate with the winding roller 6, which can play the role of unwinding the cable core and facilitate the straightening of the cable core.

[0055] When the cable core is being conveyed, the tension of the cable core can be adjusted by the cooperation of two sets of tension adjustment components, the first support wheel 9 and the second support wheel 17. This helps to keep the cable core taut during the conveying process and prevents it from becoming loose. This is beneficial to maintaining the conveying effect of the cable core. In addition, the cooperation of the two sets of tension adjustment components, the first support wheel 9 and the second support wheel 17 not only adjusts the tension of the cable core during the conveying process, but also initially straightens the cable core, which helps to improve the straightening effect of the equipment.

[0056] The cable core then passes between the straightening assembly and the two third straightening wheels 31. The cooperation between the straightening assembly and the third straightening wheels 31 facilitates the straightening of different sides of the cable core, thus achieving the function of straightening the cable core. Furthermore, the distance between the two third straightening wheels 31 can be adjusted by the drive assembly, which makes it easier for the equipment to straighten cable cores of different sizes, thereby improving the applicability of the equipment.
