Description

Technical Field

[0001] This invention relates to the field of cable recycling technology, and in particular to a device for recycling and utilizing waste high-voltage cables. Background Technology

[0002] Electric wires and cables are key transmission materials in the power industry. They are made of copper and aluminum cores and covered with an outer insulation layer. Compared with conventional cables, high-voltage cables have thicker insulation layers, multi-layer shielding structures, and armored protective layers. After they are scrapped, they must be stripped to recycle the metal core and the outer insulation layer, thereby reducing material waste and avoiding environmental pollution.

[0003] Existing wire and cable stripping equipment requires manual adjustment of the distance between the upper and lower stripping blades to accommodate cables of different sizes. This is time-consuming and labor-intensive in large-scale recycling operations. In addition, high-voltage cables are more difficult to process than conventional cables due to their multiple layers of shielding, higher insulation thickness, and armor structure. After cutting, the insulation layer of some cables is easily trapped between the wire cores and cannot be automatically separated, requiring secondary processing. Furthermore, the cables are prone to slippage and deviation during the squeezing and cutting process, leading to repeated cutting, which seriously affects recycling efficiency and quality. Summary of the Invention

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Example 1, referring to Figure 1 - Figure 2 The first embodiment of the present invention provides a waste high-voltage cable recycling device. The device includes an operating table 1, a cutting unit 2 securely mounted on the operating table 1, and a feeding unit 3 securely mounted on the cutting unit 2.

[0029] The cutting unit 2 includes a drive assembly 21 that is securely mounted on the operating table 1, which drives the cutting assembly 23 to rotate; a positioning assembly 22 that is securely mounted on the operating table 1, which cooperates with the cutting assembly 23 to perform correction when cutting the cable; and a cutting assembly 23 that is rotatably mounted on the positioning assembly 22. Both the positioning assembly 22 and the cutting assembly 23 are fixedly connected to the drive assembly 21 to cut and separate the outer sheath of the cable, while preventing the cable from shifting during cutting.

[0030] Furthermore, the unloading unit 3 includes a material distribution component 31 that is securely mounted on the positioning component 22, which guides the cut cable sheath and outputs the copper wire inside the cable, and a guide component 32 that is securely mounted on the operating table 1, which is used to collect the cable sheath in a unified manner.

[0031] During use, the waste cable to be recycled is first placed inside the positioning component 22, and the drive component 21 starts to operate, causing the cutting component 23 to rotate. At the same time, the cable is engaged and conveyed. Simultaneously, the positioning component 22 pre-corrects and conveys the cable, and the corrective component 227 inside the positioning component 22 engages and squeezes the input cable to prevent the cable from deviating or running off course when the cutting component 23 engages and cuts the cable. Through the forced correction and limiting cooperation of the drive component 21 and the positioning component 22, the cutting component 23 performs bite cutting on the cable. At the same time, the pre-meshing compression of the positioning component 22 can also cause the cable with armor to be squeezed and deformed, making it easier for the cutting component 23 to cut. In addition, the cutting component 23 can also adaptively adjust the cutting diameter of different cables, avoiding multiple adjustments when cutting cables of different sizes. After the cutting component 23 completes the cutting, the cable sheath separates to both sides and is blocked and guided by the material distribution component 31, so that all the cut sheaths are transported into the guide component 32. The guide component 32 collects the cutting waste, preventing the waste from accumulating on the operating table 1. Meanwhile, the copper wires inside the cable are directly transported out through the material distribution component 31, thus completing a complete assembly line process from positioning, correction, and preliminary compression treatment before cutting, to cooperation during the cutting process, and then to waste separation after cutting.

[0032] Example 2, refer to Figure 1 - Figure 6 This is the second embodiment of the present invention, which differs from the first embodiment in that: the drive assembly 21 includes a motor 211 fixedly mounted on the operating table 1, which drives the drive wheel 212 and the cutting assembly 23 to rotate; the drive wheel 212 fixedly mounted on the output end of the motor 211; a timing belt 213 slidably mounted on the outer wall of the drive wheel 212; and a rotating wheel 214 slidably mounted on the inner wall of the timing belt 213. The motor 211 drives the drive wheel 212 to rotate, and at the same time, the timing belt 213 on the outer wall of the drive wheel 212 synchronously drives the rotating wheel 214 to rotate.

[0033] Compared to Embodiment 1, the positioning component 22 further includes a support member 221 fixedly installed on the operating table 1; a receiving plate 222 fixedly installed on the support member 221; a connector 223 fixedly installed on the receiving plate 222; a limiting groove 224 fixedly installed on the connector 223 for limiting the movement of the limiting rod 225, while the limiting rod 225 can rotate and move inside the limiting groove 224; the limiting rod 225 slidably installed on the inner wall of the limiting groove 224 for rotating connection with the straightening member 227; and the straightening member 227 fixedly installed on the other end of the limiting rod 225 for initially compressing the cable and engaging and limiting it.

[0034] Furthermore, a spring plate 216 is slidably installed on the outer wall of the connector 223, and an adjusting wheel 215 is fixedly installed on the other end of the spring plate 216. The adjusting wheel 215 is slidably connected to the timing belt 213. When the rotating wheel 214 moves and adjusts with the cutting assembly 23, the adjusting wheel 215 moves and adjusts in conjunction with the timing belt 213, so that the drive wheel 212 can stably drive the timing belt 213 to drive the rotating wheel 214 to rotate.

[0035] Furthermore, a connecting rod 226 is rotatably mounted on the outer diameter of the limiting rod 225 for connecting the sliding block 232 and moving up and down together with the sliding block 232. A positioning component 228 is fixedly mounted on the top of the receiving plate 222 for straightening the cable. A conveying component 229 is fixedly mounted on the top of the operating table 1 for rolling the cable.

[0036] Furthermore, the cutting assembly 23 includes a rotating rod 231 fixedly mounted on the rotating wheel 214, the rotating rod 231 being connected to the rotating wheel 214 so that the rolling roller 235 rotates together; a sliding block 232 that passes through and is rotatably mounted on the outer wall of the rotating rod 231, used to cooperate with the rolling roller 235 for sliding adjustment; and an adjusting member 234 fixedly mounted on the sliding block 232, and the adjusting member 234 being fixedly connected to the connecting member 223, used to buffer the rolling roller 235 when it moves and adjusts, ensuring that the rolling roller 235 can stably fit against the surface of the internal cable.

[0037] Furthermore, the adjusting member 234 includes a mounting shell 2341 fixedly mounted on the connector 223 for rolling the return spring 2342; a return spring 2342 fixedly mounted on the inner wall of the mounting shell 2341 for connecting the tension block 2343 and restricting its movement; and a tension block 2343 fixedly mounted on the other end of the return spring 2342, and the tension block 2343 is fixedly connected to the sliding block 232, so that the sliding block 232 and the rolling roller 235 can always fit against the outer diameter of the cable of different sizes.

[0038] Furthermore, an adjusting rod 233 is rotatably mounted on the top of the sliding block 232, and the adjusting rod 233 is rotatably connected to the connecting piece 223, for adjusting the cutting width between the rolling rollers 235, and at the same time adjusting the buffer space of the adjusting piece 234.

[0039] Furthermore, a rolling roller 235 is fixedly installed at one end of the rotating rod 231 for positioning and engagement when cutting the cable. A cutting blade 236 is fixedly installed on the outer wall of the rolling roller 235 for cutting the cable. A meshing groove 237 is fixedly installed on the outer wall of the cutting blade 236, and the outer wall of the rotating rod 231 is rotatably connected to the connecting rod 226. When the cutting blade 236 is used to cut the cable, the cutting blade 236 can be stably engaged on the outer wall of the cable to prevent the cable from shifting.

[0040] During operation, the cable is first placed on the conveyor 229 and simultaneously squeezed into the positioning component 228. The positioning component 228 automatically engages and adjusts according to the cable width, performing initial straightening of the cable. Simultaneously, the cable is inserted between the straightening component 227 and the rolling rollers 235, and the motor 211 is then activated. Under the coordinated action of the drive wheel 212, the synchronous belt 213, and the rotating wheel 214, the upper and lower rolling rollers 235 begin to rotate. At the same time, the cutting blades 236 on the outer wall of the rolling rollers 235 begin to cut the cable.

[0041] Before cutting, when the cable is inserted between the rollers 235, the rollers 235 cause the rotating rod 231 and sliding block 232 to move upward due to the cable's own compression. Simultaneously, the adjusting member 234 pulls the sliding block 232 downward, ensuring that the rollers 235 and the cutting blade 236 are firmly attached to the cable surface. Furthermore, as the rollers 235 move, the rotating wheel 214 also moves synchronously. At the same time, the timing belt 213 drives the adjusting wheel 215 and spring plate 216 to move on the connecting member 223, ensuring that the drive wheel 212 and the rotating wheel 214 remain stable through the transmission of the timing belt 213.

[0042] In addition, the cutting height of the roller 235 can be adjusted by rotating the adjusting rod 233, and the buffer zone of the adjusting member 234 can be adjusted simultaneously. When the cutting blade 236 on the roller 235 cuts the cable, the straightening member 227 cooperates with the roller 235 to perform preliminary engagement and compression on the cable to prevent some cables from being unable to be cut due to the internal armor protection. Through the preliminary compression of the straightening member 227, the armor is deformed, thereby cooperating with the cutting blade 236 to complete the cutting operation.

[0043] Meanwhile, when the roller 235 is adjusting to adapt to the cable, the straightening component 227, in cooperation with the connecting rod 226 and the limiting rod 225, is also adjusted in the limiting groove 224 to match the movement of the roller 235. When the cutting blade 236 cuts the cable, the meshing groove 237 on the outer wall of the cutting blade 236 also meshes with the inside of the cable, effectively preventing the cable from shifting during cutting.

[0044] By pre-deforming the armored cable, the difficulty of cutting is reduced, and the cutting component 23 can adaptively adjust the cutting diameter, eliminating the need for manual adjustment of the stripping blade spacing and saving time and costs for large-scale recycling operations.

[0045] The remaining structure is the same as that in Example 1.

[0046] Example 3, referring to Figure 1 - Figure 8This is the third embodiment of the present invention, which differs from the second embodiment in that: the material separating component 31 includes a guide plate 311 fixedly installed on the receiving plate 222, which serves to guide the cable during cutting; it also includes a conveying roller 312 rotatably installed on the inner wall of the guide plate 311 for guiding and conveying the outer sheath of the cut cable; and an adjusting shaft 314 rotatably installed on the inner wall of the guide plate 311, and a conveying plate 313 fixedly installed on the adjusting shaft 314. The conveying plate 313 is rotatably connected to the guide plate 311. By rotating the adjusting shaft 314, the tilt angle of the conveying plate 313 can be adjusted, thereby adjusting the separation effect of waste and copper wire after the cable is cut.

[0047] Compared to embodiment 2, the guide assembly 32 further includes a waste guide 321 fixedly installed on the operating table 1, which can guide the waste outer skin and output copper wire; it also includes a waste collection component 322 fixedly installed on the waste guide 321, and the waste collection component 322 is fixedly connected to the operating table 1 for uniform collection of waste outer skin.

[0048] During use, the cable is first cut by the cooperation of the positioning component 22 and the cutting component 23. After the cutting is completed, the copper wire inside the cable and the waste material outside are separated by the conveying plate 313. At the same time, the conveying plate 313 guides the cable sheath into the conveying roller 312. Under the guidance of the conveying roller 312, the sheath enters the waste guide 321. Finally, the sheath and the waste material are collected in the waste collection component 322.

[0049] Furthermore, after the feed plate 313 separates the outer sheath, it does not affect the copper wire inside the cable, allowing the copper wire to be output stably. At the same time, the tilt angle of the feed plate 313 can be adjusted by rotating the adjusting shaft 314, thereby adapting to the width of the copper wire inside different cables. This eliminates the step of manually adjusting the spacing of the stripping blades repeatedly, saving time and costs for large-scale recycling operations. After cutting, the cable sheath is separated and collected, while the copper wire is directly conveyed out, realizing the automatic separation of the wire core and the insulation sheath without secondary processing, thus improving the efficiency and quality of cable recycling.

[0050] The remaining structure is the same as that in Example 2.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
