Description

Technical Field

[0001] This invention relates to the field of cable recycling technology, and more particularly to a cable recycling device for multi-core cables. Background Technology

[0002] Cable recycling is used to separate the rubber insulation from the copper wires of the cable for recycling.

[0003] Multi-core cables are cables with one or more insulated cores. Existing cable recycling devices mostly perform a single insulation sheath separation. For the recycling of multi-core cables, after the main cable is separated from the inner core, the inner cores are collected one by one, and then the insulation sheaths of the inner cores are separated a second time. Therefore, multi-core cables need to go through multiple separations of insulation sheaths and cores during the recycling process, which is cumbersome, time-consuming, labor-intensive, and has low recycling efficiency. Summary of the Invention

[0004] The purpose of this invention is to solve the problem of low recycling efficiency of multi-core cables in the prior art, and to propose a cable recycling device for multi-core cables to improve the recycling efficiency of multi-core cables.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cable recycling device for multi-core cables includes a frame comprising a top frame and a bottom frame. Along the cable entry direction, the frame is equipped with a main cable sheath removal assembly, a filler removal assembly, and a core cable sheath removal assembly. The main cable sheath removal assembly separates the outer sheath of the main cable; the filler removal assembly separates the inner core filler portion from each individual core wire; and the core cable sheath removal assembly separates the sheath from the core of each individual core wire.

[0007] Furthermore, the main wire sleeve removal assembly includes a main feed roller group, a cutting blade, an extension block, and an outer sleeve gripping roller arranged sequentially along the wire infeed direction.

[0008] The aforementioned main feed roller assembly is used for active feeding of the main line. Specifically, the main feed roller assembly includes an upper main feed roller and a lower main feed roller arranged in pairs. The upper main feed roller is connected to the top frame through a feed cylinder, and the lower main feed roller is rotatably connected to the base frame. The top frame is equipped with a drive unit that drives the upper main feed roller to rotate actively. The main line passes between the upper and lower main feed rollers and enters the support platform of the base frame to achieve feeding.

[0009] Furthermore, the cutting blade and extension block of the main cable removal assembly are connected to the top frame via a cutting blade telescopic cylinder. The extension block is a tapered block that expands from the tip to both sides, and the cutting blade is fixedly connected to the tip of the extension block. When the main cable passes through the cutting blade, the cutting blade is used to cut open the outer sheath of the main cable, and the extension block is used to unfold the outer sheath at the cut, so that the outer sheath separates from the inner core of the main cable.

[0010] Furthermore, the extension block is provided with a side pressing block, which is connected to the extension block through an unfolding cylinder arranged vertically on the axis. The unfolding cylinder is used to press the side pressing block onto the unfolded outer cover, so that the outer cover is spread out on the support platform of the base frame.

[0011] Furthermore, the outer sleeve gripping roller is used to grip the outer sleeve. The outer sleeve gripping roller is located below the extension block and is rotatably connected to the support platform of the base frame. A synchronous pressure roller is provided on one side of the outer sleeve gripping roller. When the outer sleeve passes between the outer sleeve gripping roller and the synchronous pressure roller, the synchronous pressure roller presses the outer sleeve against the outer sleeve gripping roller. The outer sleeve gripping roller includes a gripping needle, a rotating rod, and a gripping sleeve. The gripping needle and gripping sleeve are respectively fixedly connected to the rotating rod. The base frame is provided with a driving component to drive the rotating rod to rotate, and the rotating rod can drive the gripping needle and gripping sleeve to rotate.

[0012] Furthermore, the gripping needle is located inside the gripping sleeve, and the gripping sleeve is provided with an opening for the gripping needle to extend out, the gripping needle being positioned corresponding to the side pressure block. Preferably, the side pressure block has a recessed hole on the surface opposite to the gripping needle to accommodate the tip of the gripping needle.

[0013] When the outer jacket is spread on the gripping roller of the base support platform, the gripping needle extends from the gripping sleeve, and the tip of the gripping needle pierces through the outer jacket and enters the concave hole of the side pressure block. The gripping needle completes the gripping of the outer jacket. The gripping needle and the gripping sleeve rotate synchronously, so that the outer jacket enters between the gripping sleeve and the synchronous pressure roller, so that the outer jacket is completely separated from the inner core.

[0014] Furthermore, the base frame is equipped with an outer jacket collection box for collecting the outer jacket of the main line. The inlet of the outer jacket collection box is connected to the outlet between the gripping sleeve and the synchronous pressure roller. The outer jacket can enter the outer jacket collection box. The inlet of the outer jacket collection box is equipped with an outer jacket cutting knife, which is used to cut and collect the outer jacket.

[0015] Furthermore, the filling removal assembly includes a rolling block, a spreading seat, a positioning block, an upper baffle, a lower baffle, and a filling collection roller assembly arranged sequentially along the feed direction.

[0016] The rolling block is used to roll the inner core, separating the core wires inside. Specifically, a telescopic rod is fixedly connected to the top of the rolling block, and the telescopic rod is connected to a reciprocating slide. The reciprocating slide is slidably connected to the top frame in a direction perpendicular to the wiring direction. The top frame is equipped with a driving component to drive the reciprocating slide to move back and forth, realizing the reciprocating rolling of the inner core on the support platform by the rolling block, thereby loosening the inner core and separating the core wires from the filler.

[0017] Furthermore, the rolling and spreading seat is connected to the rolling block, and the rolling and spreading seat is used to spread the loose inner core so that the core wires are distributed in a plane. Specifically, the rolling and spreading seat includes a rolling and spreading disc and a partition plate. The rolling and spreading disc is rotatably connected to the rolling and spreading seat, and the partition plate is fixedly connected to the rolling and spreading seat. The rolling and spreading seat is provided with a driving component to drive the rolling and spreading disc to rotate.

[0018] Furthermore, the grinding disc includes a flexible contact bladder and a rigid support cover, with the flexible contact bladder connected to the lower part of the rigid support cover. The bottom of the flexible contact bladder includes a contact area and a recessed area that contact the inner core. The contact area and the recessed area are arranged adjacent to each other and spaced apart, so that the bottom of the flexible contact bladder forms a flexible friction surface. When the bottom of the flexible contact bladder rotates relative to the inner core, the core wire unfolds and fills the plane on the support platform.

[0019] The top surface of the isolation plate is in contact with more than half of the bottom of the flexible contact bladder, keeping the part of the flexible contact bladder rotating in the same direction in contact with the inner core, thereby improving the efficiency of core wire separation and expansion from the filler.

[0020] Furthermore, the positioning block is connected to the top frame via a positioning cylinder, and is used for positioning each core wire. Preferably, the positioning block includes multiple positioning strips, a simulation rod, and a simulation sleeve. Each positioning strip is slidably connected to the positioning block, and the positioning strips are also slidably connected to each other. The simulation rod is fixedly connected to the top of each positioning strip, a compression spring is provided between each positioning strip and the positioning block, and the simulation rod is movably connected to the simulation sleeve.

[0021] As the core wire and filler pass the positioning block, the positioning cylinder pushes the positioning block to press slightly against the support platform. The core wire and filler then push the corresponding positioning strip upwards, causing the simulation rod to enter the simulation sleeve. The top of the simulation rod forms half of the corresponding core wire's outline upon entering the simulation sleeve. The signal from this half-outline can be received by the controller of this cable recovery device. A signal transmitter is installed at the top of the simulation rod, and a sensor is installed inside the simulation sleeve to detect the position of the top of the simulation rod.

[0022] Furthermore, the base frame is equipped with a filler collection box and a filler collection roller assembly. The inlet of the filler collection box is located between the positioning block and the upper baffle. The filler collection roller assembly is rotatably connected to the base frame and is used to collect the filler, allowing it to enter the filler collection box and further separating the filler from the core wire.

[0023] Furthermore, a filling cutter is provided below the filling collection roller assembly at the inlet of the filling collection box. The filling cutter is used to cut the filling, which facilitates the collection of the filling collection box.

[0024] Furthermore, the upper baffle is connected to the top frame, and the lower baffle is connected to the bottom frame. The upper and lower baffles are positioned correspondingly, and the upper and lower baffles cooperate to block the filling.

[0025] Specifically, the upper baffle includes an upper baffle strip and an upper adjusting cylinder. The upper baffle strip is slidably connected to the upper baffle, and multiple upper baffle strips are also slidably and sealingly connected to each other. Multiple upper baffle strips are combined to form an upper isolation plate. The top of each upper baffle strip is connected to the upper baffle via the upper adjusting cylinder, which is used to adjust the bottom contour of the upper baffle strip.

[0026] Similarly, the lower baffle includes a lower baffle strip and a lower adjusting cylinder. The lower baffle strip is slidably connected to the lower baffle, and multiple lower baffle strips are also slidably and sealingly connected to each other. Multiple lower baffle strips are combined to form a lower isolation plate. The bottom of each lower baffle strip is connected to the lower baffle through the lower adjusting cylinder, which is used to adjust the top contour of the lower baffle strip.

[0027] Furthermore, the bottom of the upper baffle bar is opposite to the top of the lower baffle bar. After the core wire is positioned, the controller of the cable recovery device sends the position signal of the core wire to the upper and lower adjustment cylinders, so that a through hole is formed between the bottom of the upper baffle bar and the top of the lower baffle bar for the core wire to pass through. The core wire enters the core wire sleeve removal component through the through hole. The filler is isolated in front of the upper baffle bar and the lower baffle bar, and the filler can enter the inlet of the filler collection box.

[0028] Furthermore, a torsion telescopic cylinder is fixedly connected to the top of the upper baffle, and a sliding block is rotatably connected to the top of the torsion telescopic cylinder. The sliding block is slidably connected to the top frame in the direction of travel. The sliding block and the torsion telescopic cylinder work together to make the upper part of the upper baffle tilt upwards, which facilitates the filling to enter the inlet of the filling collection box downwards and be carried into the filling collection box by the filling collection roller group.

[0029] The beneficial effects of this invention are: This multi-core cable recycling device is used for the recycling of multi-core cables. This cable recycling device can cut open the outer sheath of the main wire of the cable to obtain the inner core, then separate the filling of the inner core part from the core wire, and then separate the sheath of the core wire from the core part. This cable recycling device is specifically designed for the efficient recycling of multi-core cables, with a compact structure and practical function. Attached Figure Description

[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0041] Reference Figure 1A cable recycling device for multi-core cables includes a frame comprising a top frame 1 and a bottom frame 2. Along the cable entry direction, the frame is equipped with a main cable sheath removal assembly, a filler removal assembly, and a core cable sheath removal assembly. The main cable sheath removal assembly is used to separate the outer sheath 19 of the main cable; the filler removal assembly is used to separate the filler portion of the inner core 20 from each core wire; and the core cable sheath removal assembly is used to separate the sheath and core portion of each core wire.

[0042] Furthermore, the main wire sleeve removal assembly includes a main feed roller group 3, a cutting blade 4, an extension block 5, and an outer sleeve gripping roller 6 arranged sequentially along the wire infeed direction.

[0043] The aforementioned main feed roller group 3 is used for active feeding of the main line. Specifically, the main feed roller group 3 includes an upper main feed roller 31 and a lower main feed roller 32 arranged in pairs. The upper main feed roller 31 is connected to the top frame 1 through a feeding cylinder, and the lower main feed roller 32 is rotatably connected to the base frame 2. The top frame 1 is provided with a driving component that drives the upper main feed roller 31 to rotate actively. The main line passes between the upper main feed roller 31 and the lower main feed roller 32 and enters the support platform of the base frame 2 to realize feeding.

[0044] Furthermore, the cutting blade 4 and extension block 5 of the main wire sleeve removal assembly are connected to the top frame 1 via the cutting blade telescopic cylinder 41, as shown in the reference. Figure 2 The extension block 5 is a conical block that extends from the tip to both sides, and the cutting blade 4 is fixedly connected to the tip of the extension block 5. When the main line passes through the cutting blade 4, the cutting blade 4 is used to cut open the outer jacket 19 of the main line, and the extension block 5 is used to unfold the outer jacket 19 at the cut, so that the outer jacket 19 is separated from the inner core 20 of the main line.

[0045] refer to Figure 2 and Figure 3 The extension block 5 is provided with a side pressing block 51. The side pressing block 51 is connected to the extension block 5 through an unfolding cylinder 52 that is vertically arranged on the axis. The unfolding cylinder 52 is used to press the side pressing block 51 onto the unfolded outer jacket 19, so that the outer jacket 19 is spread out on the support platform of the base frame 2.

[0046] Furthermore, the outer gripping roller 6 is used to grip the outer sleeve 19. The outer gripping roller 6 is located below the extension block 5 and is rotatably connected to the support platform of the base frame 2. A synchronous pressure roller 64 is provided on one side of the outer gripping roller 6. When the outer sleeve 9 passes between the outer gripping roller 6 and the synchronous pressure roller 64, the synchronous pressure roller 64 is used to press the outer sleeve 9 against the outer gripping roller 6. The outer gripping roller 6 includes a gripping needle 61, a rotating rod 62, and a gripping sleeve 63. The gripping needle 61 and the gripping sleeve 63 are respectively fixedly connected to the rotating rod 62. The base frame 2 is provided with a driving component to drive the rotating rod 62 to rotate. The rotating rod 62 can drive the gripping needle 61 and the gripping sleeve 63 to rotate.

[0047] Furthermore, the gripping needle 61 is located inside the gripping sleeve 63, and the gripping sleeve 63 is provided with an opening for the gripping needle 61 to extend out. The position of the gripping needle 61 corresponds to that of the side pressure block 51. Preferably, the side pressure block 51 has a recessed hole 511 on the opposite side to the gripping needle 61 to accommodate the tip of the gripping needle 61.

[0048] When the outer jacket 19 is laid out on the gripping roller 6 of the support platform of the base frame 2, the gripping needle 61 extends out from the gripping sleeve 63, and the needle tip of the gripping needle 61 pierces the outer jacket 19 and enters the concave hole 511 of the side pressure block 51. The gripping needle 61 completes the gripping of the outer jacket 19. The gripping needle 61 and the gripping sleeve 63 rotate synchronously, so that the outer jacket 19 enters between the gripping sleeve 63 and the synchronous pressure roller 64, so that the outer jacket 19 completely separates from the inner core 20.

[0049] Furthermore, the base frame 2 is provided with an outer jacket collection box 14 for collecting the outer jacket of the main line. The inlet of the outer jacket collection box 14 is connected to the discharge port between the gripping sleeve 63 and the synchronous pressure roller 64. The outer jacket 19 can enter the outer jacket collection box 14. The inlet of the outer jacket collection box 14 is provided with an outer jacket cutting knife 141, which is used to cut and collect the outer jacket 19.

[0050] Furthermore, the filling removal assembly includes a rolling block 7, a spreading seat 8, a positioning block 9, an upper baffle 10, a lower baffle 11, and a filling collection roller group 16 arranged sequentially along the feed direction.

[0051] The rolling block 7 is used to roll the inner core 20, causing the core wire 21 inside the inner core 20 to separate. Specifically, the top of the rolling block 7 is fixedly connected to a telescopic rod 71, which is connected to a reciprocating slide table 72. The reciprocating slide table 72 is slidably connected to the top frame 1 in a direction perpendicular to the wiring direction. The top frame 1 is provided with a driving component to drive the reciprocating slide table 72 to move back and forth, so as to realize the reciprocating rolling of the inner core 20 on the support platform by the rolling block 7, thereby loosening the inner core 20 and separating the core wire 21 from the filler.

[0052] Furthermore, the spreading seat 8 is movably connected to the rolling block 7 in the vertical direction. The spreading seat 8 is used to spread the loose inner core 20, so that the core wires 21 are distributed in a planar manner. Specifically, refer to... Figure 4 and Figure 5 The milling and spreading base 8 includes a milling and spreading disc 81 and a partition plate 82. The milling and spreading disc 81 is rotatably connected to the milling and spreading base 8, and the partition plate 82 is fixedly connected to the milling and spreading base 8. The milling and spreading base 8 is provided with a driving component to drive the milling and spreading disc 81 to rotate.

[0053] Furthermore, the milling disc 81 includes a flexible contact bladder 811 and a rigid support cover 812, with the flexible contact bladder 811 connected to the lower part of the rigid support cover 812. The bottom of the flexible contact bladder 811 includes a contact area 8111 and a recessed area 8112 that contact the inner core 20. The contact area 8111 and the recessed area 8112 are arranged adjacent to each other, with the contact areas 8111 spaced apart, so that the bottom of the flexible contact bladder 811 forms a flexible friction surface. When the bottom of the flexible contact bladder 811 rotates relative to the inner core 20, the core wire 21 unfolds and fills the plane on the support platform.

[0054] refer to Figure 4 The top surface of the isolation plate 82 is in contact with more than half of the bottom of the flexible contact bladder 811. The isolation plate 82 is used to isolate the bottom of the flexible contact bladder 811, keeping the part of the flexible contact bladder 811 that rotates in the same direction relative to the support platform in contact with the inner core 20, thereby improving the efficiency of separation and unfolding of the core wire 21 from the filling.

[0055] Furthermore, the positioning block 9 is connected to the top frame 1 via a positioning cylinder, and the positioning block 9 is used for positioning each core wire 21. (See reference) Figure 6 The positioning block 9 includes multiple positioning strips 91, a simulated rod 92, and a simulated sleeve 93. Each positioning strip 91 is slidably connected to the positioning block 9, and each positioning strip 91 is slidably and sealingly connected to the others. The simulated rod 92 is fixedly connected to the top of each positioning strip 91. A compression spring 94 is provided between each positioning strip 91 and the positioning block 9. The simulated rod 92 is movably connected to the simulated sleeve 93.

[0056] refer to Figure 6 When the core wire 21 and the filler pass through the positioning block 9, the positioning cylinder pushes the positioning block 9 to press slightly against the support platform. The core wire 21 and the filler then push the corresponding positioning strip 91 upwards, causing the simulation rod 92 to enter the simulation sleeve 93. The top of the simulation rod 92 forms half of the outline of the corresponding core wire 21 within the simulation sleeve 93. The signal from this half-outline can be received by the controller of this cable recovery device. A signal transmitter is installed at the top of the simulation rod 92, and a sensor is installed inside the simulation sleeve 93 to sense the position of the top of the simulation rod 92.

[0057] refer to Figure 1 The base frame 2 is equipped with a filling collection box 15 and a filling collection roller assembly 16. The inlet of the filling collection box 15 is located between the positioning pressure block 9 and the upper baffle plate 10. The filling collection roller assembly 16 is rotatably connected to the base frame 2. The filling collection roller assembly 16 is used to collect the filling, allowing the filling to enter the filling collection box 15 and completing the further separation of the filling from the core wire 21.

[0058] Furthermore, a filling cutter 151 is provided below the filling collection roller group 16 at the inlet of the filling collection box 15. The filling cutter 151 is used to cut the filling, which facilitates the collection of the filling collection box 15.

[0059] Furthermore, the upper baffle 10 is connected to the top frame 1, and the lower baffle 11 is connected to the base frame 2. The upper baffle 10 and the lower baffle 11 are positioned correspondingly, and the upper baffle 10 and the lower baffle 11 cooperate to block the filling.

[0060] refer to Figure 7 The upper baffle 10 includes an upper baffle strip 101 and an upper adjusting cylinder 102. The upper baffle strip 101 is slidably connected to the upper baffle 10, and multiple upper baffle strips 101 are also slidably and sealingly connected to each other. Multiple upper baffle strips 101 are combined to form an upper partition plate. The top of each upper baffle strip 101 is connected to the upper baffle 10 via the upper adjusting cylinder 102, which is used to adjust the bottom contour of the upper baffle strip 101.

[0061] Similarly, the lower baffle 11 includes a lower baffle strip 111 and a lower adjusting cylinder 112. The lower baffle strip 111 is slidably connected to the lower baffle 11, and multiple lower baffle strips 111 are also slidably and sealingly connected to each other. Multiple lower baffle strips 111 are combined to form a lower partition plate. The bottom of each lower baffle strip 111 is connected to the lower baffle 11 via the lower adjusting cylinder 112, which is used to adjust the top contour of the lower baffle strip 111.

[0062] Furthermore, the bottom of the upper baffle 101 is opposite to the top of the lower baffle 111, for reference. Figure 7 Once the core wire 21 is positioned, the controller of the cable recovery device sends a position signal of the core wire 21 to the upper adjustment cylinder 102 and the lower adjustment cylinder 112, so that a through hole for the core wire 21 to pass through is formed between the bottom of the upper baffle 101 and the top of the lower baffle 111. The core wire 21 enters the core wire sleeve removal assembly through the through hole, and the filler is isolated in front of the upper baffle 10 and the lower baffle 111. The filler can enter the inlet of the filler collection box 15.

[0063] Furthermore, a torsion telescopic cylinder 18 is fixedly connected to the top of the upper baffle 10, and a sliding block 17 is rotatably connected to the top of the torsion telescopic cylinder 18. The sliding block 17 is slidably connected to the top frame 1 in the directional direction. (Reference) Figure 8 The sliding block 17 and the torsion telescopic cylinder 18 work together to form the upper part of the upper baffle 10 to tilt downward, which can cause the filling feed direction V2 to move downward, so that the filling can enter the inlet of the filling collection box 15 and be carried into the filling collection box 15 by the filling collection roller group 16. The core wire 21 enters the core wire sleeve removal assembly in the feeding direction V1.

[0064] In this embodiment, the structure of the core wire sleeve removal assembly is the same as that of the main wire sleeve removal assembly. Multiple core wire sleeve removal assemblies are used to correspond to different core wires.

[0065] Unlike the main wire sleeve removal assembly, the core wire sleeve removal assembly also includes an upper slide 12 and a lower slide 13. The upper slide 12 is slidably connected to the top frame 1 in a direction perpendicular to the wire routing direction, and the lower slide 13 is slidably connected to the base frame 2 in a direction perpendicular to the wire routing direction. The upper slide 12 and the lower slide 13 move synchronously in a direction perpendicular to the wire routing direction. (Reference) Figure 1 The upper and lower rollers of the auxiliary feed roller group of the core wire sleeve removal assembly are movably connected to the upper slide table 12 and the lower slide table 13, respectively, so that the corresponding core wire 21 can enter from the auxiliary feed roller group of the core wire sleeve removal assembly. The cutting blade 4 and the extension block 5 of the core wire sleeve removal assembly are connected to the upper slide table 12. The outer gripping roller 6 and the inner sleeve collection box 131 of the core wire 21 are located on the lower slide table 13. The lower slide table 13 is also equipped with an auxiliary discharge roller 132 and a core cutting blade 133. The auxiliary discharge roller 132 is used for discharging the core of the core wire 21, and the core cutting blade 133 is used for cutting the core. A core collection box is provided at the discharge end of the cable recycling device to collect the core of the core wire.

[0066] The working process of a multi-core cable recycling device is as follows:

[0067] Step 1: The main line enters the support platform of the base frame 2 from the main feed roller group 3. The cutting blade 4 cuts open the outer jacket 19 of the main line, and the extension block 5 unfolds the outer jacket 19 at the cutting point.

[0068] Step 2: The unfolding cylinder 52 pushes the extension block 5 downward, pressing the side pressing block 51 onto the unfolded outer jacket 19, so that the outer jacket 19 is spread out on the support platform of the base frame 2; at the same time, the gripping needle 61 extends out from the gripping sleeve 63 to complete the gripping of the outer jacket 19. The gripping needle 61 and the gripping sleeve 63 rotate synchronously, and the outer jacket 19 enters between the gripping sleeve 63 and the synchronous pressure roller 64, so that the outer jacket 19 is completely separated from the inner core 20 and collected by the outer jacket collection box 14.

[0069] Step 3: The head of the inner core 20 enters below the rolling block 7. The rolling block 7 reciprocates and rolls the inner core 20 on the support platform to loosen the inner core 20 and separate the core wire 21 from the filler.

[0070] Step 4: The head of the inner core 20 enters below the rolling seat 8, the rolling block 7 stops rolling, the rolling disc 81 rotates, so that the bottom of the flexible contact bladder 811 rotates relative to the inner core 20, and the core wire 21 and the filling are spread out on the support platform.

[0071] Step 5: The core wire 21 and the filler head pass through the positioning block 9. The positioning cylinder pushes the positioning block 9 to press slightly against the support platform. The core wire 21 and the filler push the corresponding positioning strip 91 to move upward. The corresponding simulation rod 92 enters the simulation sleeve 93. The top of the simulation rod 92 forms half of the outline of the corresponding core wire 21 in the simulation sleeve 93. The signal of this half outline can be received by the controller of this cable recycling device to complete the positioning and size simulation of the core wire 21.

[0072] Step Six: After the core wire 21 is positioned, the controller of the cable recycling device assigns the position and size of the core wire 21 to the upper adjustment cylinder 102 and the lower adjustment cylinder 112, so that a through hole for the core wire 21 to pass through is formed between the bottom of the upper baffle 101 and the top of the lower baffle 111. The core wire 21 enters the core wire sleeve removal assembly through the through hole. The filler is isolated in front of the upper baffle 10 and the lower baffle 111. Then the upper baffle 10 is tilted, and the filler can enter the inlet of the filler collection box 15 and be collected by the filler collection box 15.

[0073] Step 7: The head of the core wire 21 continues to move forward, and the upper slide table 12 and the lower slide table 13 move so that the head of the core wire 21 can enter the auxiliary feed roller group of the core wire sleeve removal assembly, thereby separating the inner sleeve of the core wire 21. The separation process is the same as Step 1 and Step 2.

[0074] Step 8: The core of the core wire 21 is cut off by the core cutting knife 133 and then collected;

[0075] It is worth noting that when the head of the outer sleeve 19 is actively fed by the gripping sleeve 63 and the synchronous pressure roller 64, the head of the core wire 21 is actively fed by the auxiliary feeding roller group, and the head of the inner sleeve of the core wire 21 is actively fed, the side pressure block 51, the gripping needle 61, the rolling and spreading seat 8 and the positioning pressure block 9 stop working.

[0076] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
