Description

Technical Field

[0001] This invention belongs to the field of cable recycling technology, specifically a device for removing the metal conductor of cable insulation core. Background Technology

[0002] Cables consist of a metal conductor and an insulation layer. Used cables require proper disposal to achieve the recycling of metals (copper, aluminum, etc.) and insulation materials (plastic, rubber, etc.), reducing both resource waste and environmental pollution. Typically, the insulation layer is cut open to remove the metal conductor.

[0003] A search revealed that patent CN112309638B discloses a cable insulation core metal conductor removal device. By activating a hydraulic cylinder, the cable outer sheath can be pulled to facilitate the removal of the cable insulation core metal conductor. Simultaneously, a traction plate moves a third plate, enabling the suction head to move vertically back and forth, increasing the dust suction range and effectively removing the dust generated during the removal of the cable insulation core metal conductor.

[0004] Waste cables utilize three-point support to automatically adapt to changes in cable diameter. However, the distance between the three points is relatively large, and the waste cables are often bent. There is space between the three points where the cable bends. When the cutter cuts the insulation layer, it will cut into the metal conductor (especially aluminum and copper). The continuous friction of axial cutting will generate a large number of sparks and may even cause a fire. Summary of the Invention

[0005] The purpose of this invention is to provide a device for removing the metal conductor from the insulation core of a cable, in order to solve the problems mentioned in the background art.

[0006] The technical solution of the present invention: A device for removing the metal conductor from the insulation core of a cable, comprising a workbench, wherein a take-up roller for traction of the metal conductor is rotatably connected to the inner wall of the workbench, and further comprising:

[0007] A centering guide component includes a fixed ring, a guide cylinder fixedly installed at the center of the fixed ring, multiple equally spaced rotating cylinders rotatably connected to the guide cylinder, an arc-shaped block slidably connected to the inner wall of the rotating cylinder, and a centering guide rotating cylinder parallel to the axis of the rotating cylinder rotatably connected to one side of the arc-shaped block located inside the rotating cylinder via a rotating shaft. A first hydraulic telescopic rod is fixedly installed at the end of the fixed ring, and an inner inclined ring that contacts the arc-shaped block is fixedly installed at the end of the first hydraulic telescopic rod. The side of the arc-shaped block that contacts the inner inclined ring is an arc surface.

[0008] A cable is threaded through the center of the guide cylinder, and multiple centrally located straight rotating cylinders are arranged in a ring at equal angles around the cable.

[0009] Optionally, a protruding ring is fixedly installed on the inner wall of the inner inclined ring. The protruding ring contacts the arc surface of the arc block. The further the arc block is from the inner inclined ring, the smaller the curvature of the arc surface of the arc block.

[0010] Optionally, the unfolding component includes two parallel welcoming plates. The outer wall of the welcoming plate is rotatably connected to a motor-driven conveying roller. The inner wall of the welcoming plate is slidably connected to a counterweight. The side of the counterweight is rotatably connected to a lifting cylinder. A press-type hydraulic pump is fixedly installed between the top of the lifting cylinder and the welcoming plate. The press-type hydraulic pump is connected to a first hydraulic telescopic rod through a hydraulic pipe.

[0011] Optionally, the transmission component includes teeth, which are fixedly installed on the outer wall of the rotating drum. The arc-shaped block slides up and down along the rotating drum. A gear is rotatably connected to the inner wall of the worktable, and the gear meshes with the teeth.

[0012] Optionally, the top of the workbench is provided with an inlet deceleration component, which includes a docking ring. The docking ring is fixedly installed on the top of the workbench and located at the end of the guide cylinder. A slip ring is slidably connected inside the docking ring. A ring-shaped, equally angled retraction force-bearing rubber sheet is fixedly installed on the inner wall of the slip ring. A cable passes through the center of the plurality of retraction force-bearing rubber sheets.

[0013] Optionally, a lower insertion block is fixedly installed at the bottom of the slip ring, and a sliding switch for controlling the motor speed is slidably connected to the inner wall of the mating ring, with the bottom of the lower insertion block fixedly connected to the sliding switch.

[0014] Optionally, the top of the workbench is provided with a separator for the insulation layer of the traction cable. The separator includes two gears connected by a chain. A docking block is fixedly installed on the outer wall of the chain. A clamping plate is rotatably connected to the inner wall of the docking block. A return spring is elastically connected between the clamping plate and the docking block.

[0015] Optionally, a vertical plate is fixedly installed on the top of the workbench, a second hydraulic telescopic rod is fixedly installed on the inner wall of the vertical plate, a guide rail is fixedly installed at the end of the second hydraulic telescopic rod, the guide rail adopts a horizontal U-shaped structure, and a ball bearing is fixedly installed at the end of the clamping plate, the ball bearing sliding along the guide rail.

[0016] Optionally, a spring sheet is elastically connected between the end of the guide rail and the upright plate, and the second hydraulic telescopic rod is connected to a press-type hydraulic pump through a hydraulic pipe.

[0017] Optionally, an electric telescopic rod is fixedly installed on the inner wall of the lifting cylinder, and a cutting blade for cutting cable insulation is fixedly installed at the end of the electric telescopic rod.

[0018] Compared with the prior art, the present invention has the following beneficial technical effects:

[0019] 1. This invention uses a cable to lift a counterweight block and compress a hydraulic pump. After the hydraulic pump presses, the first hydraulic telescopic rod retracts. The larger the diameter, the less pressure the inner inclined ring exerts on the arc-shaped block. The greater the distance between the central straightening rotating cylinder and the axis of the guide cylinder, the straightening rotating cylinder can straighten cables of different diameters. Since the arc-shaped block is further away from the inner inclined ring, the curvature of the arc surface is smaller. This results in different straightening pressures on cables of different diameters from the central straightening rotating cylinder. This avoids insufficient straightening pressure on thick cables, which could cause the metal conductor to be cut, and also avoids excessive straightening pressure on thin cables, which could cause the metal conductor to be pinched and broken.

[0020] 2. In this invention, after the bent cable is straightened, the bent portion of the cable extends inside the guide cylinder. The extended portion of the cable drives the slip ring to move. The slip ring, the lower insert block, and the sliding switch work together to slow down the rotation speed of the conveying roller, thereby slowing down the speed at which the conveying roller delivers the cable into the guide cylinder. This prevents the straightened portion of the cable from extending and accumulating inside the guide cylinder after being straightened, thus avoiding conveying congestion.

[0021] 3. As the cable diameter changes, the clamping force applied by the two clamps to the cable is non-linear. The insulation layer of the thicker cable experiences greater resistance when separating from the metal conductor, so the clamping force of the two clamps on the thicker cable is greater; the insulation layer of the thinner cable is thinner, so the clamping force on the thinner cable is smaller to avoid being clamped and broken.

[0037] Example 1

[0038] This embodiment proposes a device for removing the metallic conductor from the insulation core of a cable, such as... Figures 1 to 6 As shown, the device includes a workbench 1, and a take-up roller 2 for pulling a metal conductor is rotatably connected to the inner wall of the workbench 1. The metal conductor is pulled by rotating the take-up roller 2, thereby pulling the cable.

[0039] The top of the workbench 1 is provided with a central guide 3 for a straight cable. The central guide 3 includes an unfolding component, which includes two parallel welcoming plates 31. The outer wall of the welcoming plate 31 is rotatably connected to a motor-driven conveying roller 7, and the transmission cable is assisted by the conveying roller 7.

[0040] A counterweight 33 is slidably connected to the inner wall of the welcoming plate 31. A lifting cylinder 32 is rotatably connected to the side of the counterweight 33. A press-type hydraulic pump 34 is fixedly installed between the top of the lifting cylinder 32 and the welcoming plate 31. The larger the diameter of the cable, the higher the lifting cylinder 32 is lifted. The lifting cylinder 32 uses the counterweight 33 to press the press-type hydraulic pump 34.

[0041] A fixing ring 35 is fixedly installed on the top of the workbench 1. A guide cylinder 36 is fixedly installed at the center of the fixing ring 35. Multiple equally spaced rotating cylinders 37 are rotatably connected to the guide cylinder 36. An arc-shaped block 39 is slidably connected to the inner wall of the rotating cylinder 37. A centrally located straight guide cylinder 311 parallel to the axis of the rotating cylinder 37 is rotatably connected to one side of the arc-shaped block 39 inside the rotating cylinder 37 via a rotating shaft. A cable is threaded through the center of the guide cylinder 36. Multiple centrally located straight guide cylinders 311 are arranged in a ring at equal angles around the cable. An electric telescopic rod is fixedly installed on the inner wall of the lifting cylinder 32. A cutting blade 5 for cutting the cable insulation layer is fixedly installed at the end of the electric telescopic rod. The cutting position can be adjusted by extending and retracting the cutting blade 5.

[0042] The end of the fixed ring 35 is fixedly installed with a first hydraulic telescopic rod 313, and the end of the first hydraulic telescopic rod 313 is fixedly installed with an inner inclined ring 310 that contacts the arc-shaped block 39.

[0043] The counterweight 33 is lifted by the cable, thereby compressing the press-type hydraulic pump 34. The larger the diameter of the cable, the more the press-type hydraulic pump 34 is compressed, the more the first hydraulic telescopic rod 313 retracts, and the less the inner inclined ring 310 squeezes the arc-shaped block 39. The centering guide cylinder 311 on the side of the arc-shaped block 39 is farther from the axis of the guide cylinder 36. The smaller the diameter of the cable, the less the press-type hydraulic pump 34 is compressed, the less the first hydraulic telescopic rod 313 retracts, the more the inner inclined ring 310 squeezes the arc-shaped block 39, and the closer the centering guide cylinder 311 on the side of the arc-shaped block 39 is to the axis of the guide cylinder 36. Thus, the spacing between multiple centering guide cylinders 311 can be adjusted according to different cable diameters, so that multiple centering guide cylinders 311 can adapt to different cable diameters. At the same time, multiple centering guide cylinders 311 keep the cable on the axis of the guide cylinder 36, which plays a role in centering the cable.

[0044] The side of the arc-shaped block 39 that contacts the inner inclined ring 310 is an arc surface. A protruding ring is fixedly installed on the inner wall of the inner inclined ring 310. The protruding ring contacts the arc surface of the arc-shaped block 39. The further the arc-shaped block 39 is from the inner inclined ring 310, the smaller the curvature of the arc surface of the arc-shaped block 39. Therefore, when the first hydraulic telescopic rod 313 extends and uses the inner inclined ring 310 to squeeze the arc-shaped block 39, the movement of the arc-shaped block 39 is not linear. The larger the diameter of the cable, the thicker its insulation layer and the larger the diameter of the metal conductor, the less likely it is to be straightened, so more force is needed. On the other hand, the smaller the diameter of the cable, the thinner its insulation layer and the smaller the diameter of the metal conductor, the easier it is to be straightened, but it is also easier to be pinched off. The further the arc block 39 is from the inner inclined ring 310, the less curved the arc surface of the arc block 39 is, so that cables of different diameters are subjected to different guiding pressures by the central guiding rotating cylinder 311. The larger the diameter of the cable, the greater the guiding pressure, and the smaller the diameter of the cable, the less the guiding pressure.

[0045] The top of the workbench 1 is provided with an unfolding component connected to the centrally guided rotating cylinder 311. The transmission component includes a tooth 38, which is fixedly installed on the outer wall of the rotating cylinder 37. The arc-shaped block 39 slides up and down along the rotating cylinder 37. The inner wall of the workbench 1 is rotatably connected to a gear 312 connected to the output end of the motor. The gear 312 meshes with the tooth 38.

[0046] The motor drives the gear 312 to rotate, which in turn drives the tooth 38 to rotate. The tooth 38 drives the rotating drum 37 and the arc block 39 to rotate, so that the centering guide rotating drum 311 on the side of the arc block 39 rotates around the cable, thereby straightening each part of the cable and avoiding bending.

[0047] The more the hydraulic pump 34 is compressed, the greater the force required to press the clamping plate 64, thus allowing the lifting cylinder 32 to apply different pressures to cables of different diameters, avoiding the influence of cable bending on the measurement of cable diameter by the lifting cylinder 32 and the conveying roller 7.

[0048] In this embodiment, the counterweight 33 is lifted by the cable to compress the press-type hydraulic pump 34. After the press-type hydraulic pump 34 presses, the first hydraulic telescopic rod 313 retracts. The larger the diameter, the less the inner inclined ring 310 squeezes the arc-shaped block 39. The central straightening rotating cylinder 311 is farther away from the axis of the guide cylinder 36, so that the central straightening rotating cylinder 311 guides and straightens cables of different diameters. Since the arc-shaped block 39 is farther away from the inner inclined ring 310, the curvature of the arc surface of the arc-shaped block 39 is smaller. This makes the straightening pressure of the central straightening rotating cylinder 311 on cables of different diameters different. This avoids the central straightening rotating cylinder 311 from having insufficient straightening pressure on thick cables, which would cause the metal conductor to be cut. At the same time, it avoids the central straightening rotating cylinder 311 from having excessive straightening pressure on thin cables, which would cause the metal conductor to be pinched and broken.

[0049] Example 2

[0050] Based on Embodiment 1, this embodiment proposes a device for removing the metallic conductor from the insulation core of a cable, such as... Figures 5 to 7 As shown, the top of the workbench 1 is provided with an inlet deceleration component 4. The inlet deceleration component 4 includes a docking ring 41. The docking ring 41 is fixedly installed on the top of the workbench 1 and located at the end of the guide cylinder 36. A slip ring 42 is slidably connected inside the docking ring 41. A ring-shaped, equally angled retraction force-bearing rubber sheet 43 is fixedly installed on the inner wall of the slip ring 42. A cable passes through the center of the multiple retraction force-bearing rubber sheets 43.

[0051] During cable transmission, the cable uses the retracting force-bearing rubber sheet 43 to drive the slip ring 42 to the extreme position at the left end of the docking ring 41. After being straightened by multiple centrally aligned straightening rotating cylinders 311, the curved cable will extend towards the docking ring 41 after its curved part is straightened. When the curved part of the cable is straightened, the cable will retract, and the cable uses the retracting force-bearing rubber sheet 43 to drive the slip ring 42 to move towards the extreme position at the right end of the docking ring 41.

[0052] A lower insertion block 44 is fixedly installed at the bottom of the slip ring 42, and a sliding switch 45 for controlling the motor speed is slidably connected to the inner wall of the mating ring 41. The bottom of the lower insertion block 44 is fixedly connected to the sliding switch 45.

[0053] The lower insertion block 44 is driven to slide by the slip ring 42. The lower insertion block 44 adjusts the position of the sliding switch 45 to change the speed of the motor, thereby slowing down the speed at which the conveying roller 7 conveys the cable into the guide cylinder 36.

[0054] In this embodiment, after the bent cable is straightened, the bent portion of the cable extends within the guide cylinder 36. The extended portion of the cable drives the slip ring 42 to move. The slip ring 42, the lower insert block 44, and the sliding switch 45 work together to slow down the rotation speed of the conveying roller 7. This slows down the speed at which the conveying roller 7 delivers the cable into the guide cylinder 36, preventing the straightened portion of the cable from extending and accumulating within the guide cylinder 36 after being straightened, thus avoiding conveying congestion.

[0055] Example 3

[0056] Based on the above embodiment one or embodiment two, this embodiment proposes a device for removing the metal conductor of the cable insulation core, such as... Figure 8 and Figure 9 As shown, the top of the workbench 1 is equipped with a separator 6 for the insulation layer of the traction cable. The separator 6 includes two gears 61 connected by a chain 62. A docking block 63 is fixedly installed on the outer wall of the chain 62. Two symmetrically arranged clamping plates 64 are rotatably connected to the inner wall of one docking block 63. A return spring is elastically connected between the clamping plate 64 and the docking block 63. The docking block 63 and the clamping plate 64 form a clamp.

[0057] The gear 61 drives the chain 62 to rotate, causing the clamp to pull the cable insulation layer, and cooperates with the winding roller 2 to wind up the metal conductor, thereby separating the metal conductor and the insulation layer.

[0058] A vertical plate 66 is fixedly installed on the top of the workbench 1. A second hydraulic telescopic rod 67 is fixedly installed on the inner wall of the vertical plate 66. A guide rail 68 is fixedly installed at the end of the second hydraulic telescopic rod 67. The guide rail 68 adopts a horizontal U-shaped structure. A ball bearing 65 is fixedly installed at the end of the clamping plate 64. The ball bearing 65 slides along the guide rail 68. A spring plate is elastically connected between the end of the guide rail 68 and the vertical plate 66. The second hydraulic telescopic rod 67 is connected to a push-type hydraulic pump 34 through a hydraulic pipe.

[0059] When the clamping plate 64 moves into the interior of the upright plate 66, the ball bearings 65 at the end of the clamping plate 64 move along the spring plate and guide rail 68. Two second hydraulic telescopic rods 67 are provided and are symmetrical about the horizontal center line of the upright plate 66. Rubber serrations for increasing friction are fixedly installed on the push-type hydraulic pump 34.

[0060] The larger the diameter of the cable, the more the press-type hydraulic pump 34 is pressed, resulting in a longer extension of the second hydraulic telescopic rod 67, closer parallelism of the clamping plates 64, and a larger opening between the two clamping plates 64; the smaller the diameter of the cable, the less the press-type hydraulic pump 34 is pressed, resulting in a shorter extension of the second hydraulic telescopic rod 67 and a smaller opening between the two clamping plates 64.

[0061] Since the clamping plate 64 forms a lever on the mating block 63, as the clamping plate 64 changes from parallel to inclined, the angle change at the end where the ball 65 is located is smaller under the same height change, that is, the speed at which the opening of the two clamping plates 64 becomes smaller is slower.

[0062] Therefore, the two clamping plates 64 apply different clamping forces to different cables, and the force changes non-linearly. The clamping force of the two clamping plates 64 is greater for thick cables and less for thin cables to avoid them being clamped and broken.

[0063] In this embodiment, as the cable diameter changes, the clamping force applied by the two clamping plates 64 to the cable is nonlinear. The insulation layer of the thick cable experiences greater resistance after separating from the metal conductor, so the clamping force of the two clamping plates 64 on the thick cable is greater; the insulation layer of the thin cable is thinner, so the clamping force on the thin cable is smaller to avoid being clamped and broken.

[0064] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
