Description

Technical Field

[0001] The present invention belongs to the technical field of cable recycling, and specifically relates to a power cable circumcision device. Background Art

[0002] A cable is an insulated wire composed of one or more mutually insulated conductive wire cores enclosed in a sealed sheath. A protective covering layer can be coated outside the sealed sheath. It is used to transmit and distribute electrical energy or convey electrical signals. The main difference between it and ordinary wires is that the cable is larger in size and more complex in structure. Cables are mostly used for control installation, connecting equipment, transmitting electricity, etc.

[0003] After old cables are recycled, the metal inside needs to be extracted. Therefore, these cables need to be circumcised to separate the outer sheath and the inner cable core of the cable. When the existing circumcision machine peels a long cable, it will first cut the cable into small segments, and then cut and peel the small segments of the cable. This causes the cutting tool to wear more severely, and it is easy to mix with the residual outer skin attached to the outer surface when collecting small segments of the cable, and further cleaning work is required, which is very inconvenient and needs to be improved. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the technical solution adopted by the present invention to solve its technical problems is: a power cable circumcision device, including a power base, a pulling cylinder device is arranged on the left side of the inner wall of the power base, a cutting device is arranged on the right side of the inner wall of the pulling cylinder device, a thick cable is arranged at the axis center of the inner wall of the cutting device, and a limiting device is arranged on the right side of the inner wall of the power base;

[0005] The pulling cylinder device includes a receiving cylinder shell, an inner sliding ring plate is arranged on the right side of the inner wall of the receiving cylinder shell, traction ropes are symmetrically arranged on the side of the outer surface of the inner sliding ring plate away from the cutting device, and one end of the traction rope away from the inner sliding ring plate is fixedly connected to a winding device;

[0006] The cutting device includes an axis limiting ring, and tangent modules are uniformly arranged on the outer surface of the axis limiting ring; each tangent module includes a filling shell, a sliding slice is slidably connected to the axis center of the inner wall of the filling shell, the bottom part of the sliding slice is an arc-shaped blade with a groove, and the upper part is a sliding cylinder structure that can slide along the axis center of the filling shell. Insert rod connectors are symmetrically arranged on both sides of the top of the sliding slice, and one end of the insert rod connector away from the sliding slice is fixedly connected to an inner pulling cylinder. The inner pulling cylinder controls the sliding slice to perform up and down sliding movement through the insert rod connector. A steering cutting rod is slidably connected to the inner wall of the sliding slice, the bottom end of the steering cutting rod is a sharp blade, and the top end of the steering cutting rod is rotatably connected to a control outer cylinder. The control outer cylinder can control the rod body of the steering cutting rod to rotate, thereby changing the direction of the blade at the bottom end of the steering cutting rod.

[0007] Further, the number of the tangent modules is four. The outer surface of the filling housing is fixedly connected to the outer surface of the axial center limiting ring. One side of the outer surface of the filling housing away from the axial center limiting ring is fixedly connected to the right side of the inner wall of the storage cylinder shell. The outer surface of the plug rod connector is slidably connected to the axial center of the inner cavity of the filling housing through a through hole.

[0008] Further, a thick cable is arranged at the axial center of the inner wall of the axial center limiting ring. The outer surface of the sliding slice is slidably connected to the inner cavity of the axial center limiting ring, and the bottom end of the sliding slice is pressed against the outer surface of the thick cable. The outer surface of the control outer cylinder is fixedly connected to the outer surface of the storage cylinder shell. The top end of the steering cutting rod extends to the outside of the storage cylinder shell through a through hole.

[0009] Further, the side surface of the inner sliding ring plate is slidably connected to the right side of the inner wall of the storage cylinder shell through a return spring. The number of the winding devices is two. The outer surfaces of the winding devices are fixedly connected to the inner wall of the storage cylinder shell. A sliding rotating plate is rotatably connected to the outer surface of the storage cylinder shell. The storage cylinder shell rotates around the turning cutting groove on the outer surface of the sliding rotating plate through the rollers inside the sliding rotating plate, so that the arc-shaped blade at the bottom end of the sliding slice can perform circumferential cutting on the outer surface of the thick cable. The bottom end of the sliding rotating plate is slidably connected to the inner wall of the power base.

[0010] Further, the limiting device includes a horizontal sliding box. The bottom end of the horizontal sliding box is fixedly connected to a height-adjusting rod. The bottom end of the outer surface of the height-adjusting rod is slidably connected to the inner wall of the power base through a roller. A wire clamping device is arranged on the top of the horizontal sliding box. The horizontal sliding box includes a grooved box shell. The bottom of the inner wall of the grooved box shell is fixedly connected to a pull plate inner box. Bent connecting plates are symmetrically arranged on both sides of the inner cavity of the pull plate inner box. The top ends of the bent connecting plates are fixedly connected to side pressing pull plates.

[0011] Further, the wire clamping device includes a guiding rotating shaft. Flexible connecting plates are symmetrically arranged on both sides of the outer surface of the guiding rotating shaft. One end of the flexible connecting plate away from the guiding rotating shaft is fixedly connected to a fixed hard shell. The side positions of the flexible connecting plates on the upper and lower sides can rotate around the guiding rotating shaft, so that the flexible connecting plates are deformed. Since the distance between the fixed hard shells on the upper and lower sides is reduced, the clamping force on the thick cable will increase. Fixed motors are uniformly arranged on the inner wall of the fixed hard shell. A friction concave wheel is fixedly connected to the outer surface of the output shaft of the fixed motor. When pressing the thick cable, the squeezing force of the friction concave wheels on the upper and lower sides on the thick cable will also increase.

[0012] Further, the outer surface of the flexible connecting plate is rotationally connected to the outer surface of the guiding rotating shaft through a rotating cutting groove. The outer surface of the friction cam is mutually extruded with the outer surface of the thick cable. The top of the side pressing and pulling plate is rotationally connected to the upper part of the outer surface of the fixed hard shell. The top end of the bent connecting plate extends to the outside of the pulling plate inner box, and the top of the outer surface of the bent connecting plate is slidably connected to the inner cavity of the grooved box shell through an outer cutting sliding groove. The outer surface of the lower fixed hard shell is fixedly connected to the center of the upper surface of the grooved box shell.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. The sharp face at the bottom of the sliding slicer of the device first performs a circumferential cutting operation on the thick cable, and then, with the cutting groove generated by the circumferential cutting, the sharp face at the bottom of the steering cutting rod performs a transverse cutting operation on the outer skin of the thick cable. Through the pushing action of the axial center limiting ring, the cable skin is completely peeled off from the cable core. Since the sliding slicer and the steering cutting rod only contact the outer surface of the cable when performing corresponding operations, the force application directions of their own sharp faces are the same as the direction of the cutting edge, thereby effectively reducing the wear problem of the cutting edge and improving the service life of the cutting tool.

[0015] 2. The device can cut the cable skin sleeved on the outer surface of the cable core into four strip-shaped cable skins. At this time, peeling off the cable skin can effectively reduce the residual amount of the cable skin on the outer surface of the cable core, and when the axial center limiting ring slides from right to left, the resistance generated by the cable skin on the axial center limiting ring will be smaller, making the peeling work easier, and the resistance received by the receiving cylinder shell will also be smaller, thereby reducing the load of the power base and achieving the effect of easily peeling the cable skin.

[0016] 3. The device can perform a cyclic cutting operation on a long whole thick cable to completely peel off the cable skin on the outer surface of the cable. Since the peeled cable skin will be pushed to the left by the inner sliding ring plate after each cutting and gathered in the left area of the receiving cylinder shell to complete the collection work of the cable skin, the internal cable core and cable skin will ultimately achieve a zoning effect, avoiding the problem that the separated cable core and cable skin are mixed together again, resulting in a more cumbersome and inconvenient cleaning work.

[0017] 4. The limiting device of the device can not only push the external thick cable into the receiving cylinder shell to perform a cyclic cutting operation, but also fix the right side of the thick cable when the axial center limiting ring slides from right to left to prevent the problem that the whole cable is driven by the axial center limiting ring and the cable outer skin cannot be peeled off. Since the flexible connecting plate has a certain deformation ability, when fixing the thick cable, the thick cable will not be cut due to the excessive extrusion force exerted on it by the fixed hard shell, ensuring that a long thick cable can achieve a continuous processing effect in this device.

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thus design various embodiments with various modifications suitable for specific purposes.

[0031] Example 1, please refer to Figures 1-5 , the present invention provides a technical solution: a power cable circumcision device, including a power base 1, a drawing cylinder device 3 is arranged on the left side of the inner wall of the power base 1, a cutting device 4 is arranged on the right side of the inner wall of the drawing cylinder device 3, a thick cable 5 is arranged at the axis center of the inner wall of the cutting device 4, and a limiting device 2 is arranged on the right side of the inner wall of the power base 1;

[0032] The drawing cylinder device 3 includes a receiving cylinder shell 32, an inner sliding ring plate 31 is arranged on the right side of the inner wall of the receiving cylinder shell 32, traction ropes 33 are symmetrically arranged on the outer surface of the inner sliding ring plate 31 on the side far from the cutting device 4, and one end of the traction rope 33 far from the inner sliding ring plate 31 is fixedly connected to a winding device 34;

[0033] The cutting device 4 includes an axis limiting ring 41, and tangent modules 42 are uniformly arranged on the outer surface of the axis limiting ring 41; the tangent module 42 includes a filling outer shell 421, a sliding slice 424 is slidably connected to the axis center of the inner wall of the filling outer shell 421, the bottom part of the sliding slice 424 is a grooved arc-shaped blade, and the upper part is a sliding cylinder structure that can slide along the axis center of the filling outer shell 421. On both sides of the top of the sliding slice 424, there are symmetrically arranged plug rod connectors 425. One end of the plug rod connector 425 far from the sliding slice 424 is fixedly connected to an internal drawing cylinder 426. The internal drawing cylinder 426 can drive the output rod body at the top to perform up and down sliding movement through the internal motor, functioning as a power source. The internal drawing cylinder 426 controls the up and down sliding movement of the sliding slice 424 through the plug rod connector 425. A steering cutting rod 423 is slidably connected to the inner wall of the sliding slice 424. The bottom end of the steering cutting rod 423 is a sharp blade, and the top end of the steering cutting rod 423 is rotatably connected to a control outer cylinder 422. The control outer cylinder 422 can control the rod body part of the steering cutting rod 423 to rotate, thereby changing the direction of the blade at the bottom end of the steering cutting rod 423.

[0034] The number of the tangent modules 42 is four. The outer surface of the filling outer shell 421 is fixedly connected to the outer surface of the axis limiting ring 41. The side of the outer surface of the filling outer shell 421 far from the axis limiting ring 41 is fixedly connected to the right side of the inner wall of the receiving cylinder shell 32. The outer surface of the plug rod connector 425 is slidably connected to the axis center of the inner cavity of the filling outer shell 421 through a through hole.

[0035] At the axis center of the inner wall of the axis limit ring 41, a thick cable 5 is provided. The outer surface of the sliding slice 424 is slidably connected to the inner cavity of the axis limit ring 41, and the bottom end of the sliding slice 424 is pressed against the outer surface of the thick cable 5. The outer surface of the control outer cylinder 422 is fixedly connected to the outer surface of the storage cylinder shell 32. The top end of the steering cutting rod 423 extends to the outside of the storage cylinder shell 32 through the through hole.

[0036] The side of the inner sliding ring plate 31 is slidably connected to the right side of the inner wall of the storage cylinder shell 32 through a return spring. The number of winding devices 34 is two, and the outer surfaces of the winding devices 34 are fixedly connected to the inner wall of the storage cylinder shell 32. The outer surface of the storage cylinder shell 32 is rotatably connected to a sliding transfer plate 35. The sliding transfer plate 35 enables the storage cylinder shell 32 to rotate axially around the rotation cutting groove on the outer surface of the sliding transfer plate 35 through the internal rollers, so that the arc-shaped blade at the bottom end of the sliding slice 424 can perform circumferential cutting on the outer surface of the thick cable 5, and the bottom end of the sliding transfer plate 35 is slidably connected to the inner wall of the power base 1.

[0037] Before using this device to perform circumferential cutting on the cable, pass the thick cable 5 through the axis centers of the limit device 2 and the cutting device 4 in sequence, ensure that the left end of the thick cable 5 is inserted into the interior of the storage cylinder shell 32, and then complete the online work to prepare for cutting the thick cable 5.

[0038] Inside each tangent module 42, the sliding slice 424 is pushed downward towards the filling outer shell 421 by means of a downward pull rod connecting part 425. At this time, the bottom end of the sliding slice 424 is pressed against the part of the thick cable 5 inserted into the axis center of the axis limit ring 41. Subsequently, the sliding transfer plate 35 controls the left storage cylinder shell 32 to rotate, and the built-in pulling cylinder 426 also continuously applies a downward pressure on the sliding slice 424 through the rod connecting part 425, thereby enabling the sliding slice 424 to achieve the effect of circumferentially cutting the outer skin of the thick cable 5.

[0039] After the circumferential cutting of the sliding slice 424 is completed, the bottom part of the sliding slice 424 is retracted into the inner part of the axial limiting ring 41 through the built-in draw tube 426, without contacting the thick cable 5. Then, the outer cylinder 422 is controlled to push the steering cutting rod 423 downward, so that the sharp surface at the bottom end of the steering cutting rod 423 is inserted into the cut groove generated by the circumferential cutting of the thick cable 5. At this time, the limiting device 2 clamps and fixes the right side of the cable. Subsequently, the power base 1 pushes the sliding rotating plate 35 to the left, and the axial limiting ring 41 slides along the outer surface of the thick cable 5 from right to left, so that the bottom end of the steering cutting rod 423 performs a transverse sliding cutting operation on the outer skin of the thick cable 5. At this time, with the ring cut as the base point, the outer skin of the thick cable 5 on the left side that is slid cut by the steering cutting rod 423 will be divided into four cut strips, and will be peeled off from the cable core under the pushing action of the axial limiting ring 41 and fall into the inner part of the storage cylinder shell 32. Then, the power base 1 resets the sliding rotating plate 35 to the right, the limiting device 2 releases the thick cable 5, and pushes the cable to the left, thereby realizing the effect of circularly cutting the outer skin of the cable until the outer skin of the entire cable is completely cut.

[0040] After each completion of the cable skin peeling work, the winding device 34 on the left side will push the inner sliding ring plate 31 along the inner wall of the storage cylinder shell 32 to the left by winding and pulling the traction rope 33. At this time, it sweeps through the inner area of the storage cylinder shell 32, and the peeled cable skin will be pushed by the inner sliding ring plate 31 and gathered in the left area of the storage cylinder shell 32 to complete the collection work of the cable skin.

[0041] Embodiment 2, please refer to Figures 1-11 , the present invention provides a technical solution: on the basis of Embodiment 1, the limiting device 2 includes a horizontal sliding box 21. The bottom end of the horizontal sliding box 21 is fixedly connected with a height-adjusting rod 23. The bottom end of the outer surface of the height-adjusting rod 23 is slidably connected with the inner wall of the power base 1 through rollers. A wire clamping device 22 is arranged on the top of the horizontal sliding box 21. The horizontal sliding box 21 includes a slotted box shell 211. The bottom of the inner wall of the slotted box shell 211 is fixedly connected with a pull plate inner box 214. The two sides of the inner cavity of the pull plate inner box 214 are symmetrically provided with bent connecting plates 213. The top ends of the bent connecting plates 213 are fixedly connected with side pressure pull plates 212. As Figure 10 shown, a chute allowing the top ends of the bent connecting plates 213 to slide up and down is opened at a position above the slotted box shell 211. The slotted box shell 211 drives the bottom ends of the bent connecting plates 213 to perform up and down sliding movements through the way of rotational friction of the inner cavity roller shaft, so as to achieve the effect of pulling the side pressure pull plate 212.

[0042] The wire clamping device 22 includes a guiding rotating shaft 221. On both sides of the outer surface of the guiding rotating shaft 221, flexible connecting plates 223 are symmetrically arranged. One end of the flexible connecting plate 223 away from the guiding rotating shaft 221 is fixedly connected with a fixed rigid shell 222. The side positions of the flexible connecting plates 223 on the upper and lower sides can rotate around the guiding rotating shaft 221, thereby deforming the flexible connecting plates 223. Since the distance between the fixed rigid shells 222 on the upper and lower sides decreases, the clamping force on the thick cable 5 will increase. The inner wall of the fixed rigid shell 222 is uniformly provided with fixed motors 224. The outer surface of the output shaft of the fixed motor 224 is fixedly connected with friction concave wheels 225. When pressing the thick cable 5, the extrusion force of the friction concave wheels 225 on the upper and lower sides on the thick cable 5 will also increase.

[0043] The outer surface of the flexible connecting plate 223 is rotationally connected with the outer surface of the guiding rotating shaft 221 through a rotating cutting groove. The outer surface of the friction concave wheel 225 is mutually extruded with the outer surface of the thick cable 5. The top of the side pressure pulling plate 212 is rotationally connected with the upper part of the outer surface of the fixed rigid shell 222. The top end of the bent connecting plate 213 extends to the outside of the pulling plate inner box 214, and the top of the outer surface of the bent connecting plate 213 is slidably connected with the inner cavity of the slotted box shell 211 through an outer cutting sliding groove. The outer surface of the lower fixed rigid shell 222 is fixedly connected with the center of the upper surface of the slotted box shell 211.

[0044] When performing the cable pushing work, the fixed rigid shell 222 drives the thick cable 5 to slide from right to left along the center of the fixed rigid shell 222 through the friction concave wheels 225 on the upper and lower sides, so as to continuously supply the cable to the cutting device 4. When it is necessary to clamp the cable for peeling work, the bottom pulling plate inner box 214 will pull the side pressure pulling plate 212 downward through the bent connecting plate 213. The fixed rigid shell 222 presses down the flexible connecting plate 223 to deform the flexible connecting plate 223, and clamps the cable by clamping the thick cable 5 through the friction concave wheels 225 on both sides.

[0045] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art without special instructions and limitations.
