Abstract

This invention relates to the field of cable processing technology and discloses a cable stripping and recycling device, including a machine tool and a cable cutting system above it. The cable cutting system includes a mounting cover fixed to the top wall of the machine tool and two cutting feed wheels that are rotatably mounted inside the mounting cover and are positioned vertically opposite each other. The two cutting feed wheels rotate in opposite directions along the wire feeding direction to cut the cable armor layer and apply axial thrust. A stripping sleeve is provided on the front side of the mounting cover and is coaxial with the two wheel tracks. It slides in the guide rail on the top wall of the machine tool. A co-transmission system is connected to the stripping sleeve via a rocker arm and drives it to move linearly along the cable direction. In the working state, the co-transmission system drives the two cutting feed wheels to rotate in opposite directions, synchronously cutting the upper and lower ends of the armor layer to create a gap. At the same time, it drives the rocker arm to swing circumferentially, causing the stripping sleeve to insert into the gap and apply axial shearing impact force to the adhered part, thereby realizing the automatic separation of the armor layer and the wire core.

Description

Technical Field

[0001] This invention relates to the field of cable processing technology, and more specifically to a cable stripping and recycling device. Background Technology

[0002] Cable stripping devices are commonly used equipment in cable recycling, splicing, and processing. Their main function is to physically separate the outer insulation (such as rubber, PVC, etc.) of the cable from the inner metal core (copper, aluminum, etc.). A typical cable stripping process includes three steps: positioning, cutting, and stripping. First, the cable is fixed by rollers or manually. Then, a cutter is used to cut into the insulation layer. Finally, the insulation layer is separated from the conductor by pulling or pushing. To achieve the above functions, existing stripping devices are usually equipped with key components such as feed / output wheels, cutting blades, drive systems, and control systems.

[0003] For example, Chinese patent document CN212875270U discloses a stripping device for cable processing, which includes a frame, a feeding mechanism for feeding cables on the frame, a stripping mechanism for peeling off the cable sheath on one side of the feeding mechanism, and a cutting mechanism for cutting off the stripped cable sheath on one side of the stripping mechanism. The device feeds cables of different specifications through the feeding mechanism, and performs cutting operations on the upper and lower ends of the cable simultaneously through the stripping mechanism. The cutting depth can be flexibly adjusted according to the cable specifications. Then, the cutting mechanism cuts off the separated cable sheath, which improves the flexibility and separation quality of stripping to a certain extent.

[0004] However, in practical applications, the aforementioned existing technologies still have the following shortcomings: During the stripping process, simply using the stripping mechanism to simultaneously cut the upper and lower ends of the cable often makes it difficult to completely and smoothly peel the insulation layer (especially the armor layer or other thick or complex outer sheaths) from the surface of the wire core; in actual operation, it is often necessary for operators to pull the cut insulation layer outwards to fully separate it from the surface of the wire core, and manual intervention still accounts for a considerable proportion; this affects the automation level and overall efficiency of the stripping operation to some extent, and increases labor costs and operational intensity. Summary of the Invention

[0005] Based on the above background technology, the technical problem that this application actually aims to solve is: how to improve the automatic stripping effect of the cable stripping device on the armor layer without relying on manual pulling, so as to achieve full separation of the armor layer and the wire core.

[0006] This invention provides the following technical solution: a cable stripping and recycling device, comprising a machine tool and a cable slitting system located above it for axially cutting the armor layer along the surface of the cable. The cable slitting system includes a mounting cover fixed to the top wall of the machine tool, and two cutting feed wheel sets arranged vertically opposite each other and rotatably mounted inside the mounting cover. The two cutting feed wheel sets rotate in opposite directions along the cable feeding direction to cut the armor layer of the cable inserted therein while applying axial thrust, controlling the cable to continuously feed forward to complete subsequent cutting; a cooperative transmission system is provided on one side of the cable slitting system to control its movement, within the mounting cover. The front side is equipped with a stripping sleeve that is coaxial with the clamping area between the upper and lower cutting feed wheel sets. It slides linearly within a guide rail fixed to the top wall of the machine tool. The cooperative transmission system is connected to the stripping sleeve via a rocker arm. In operation, the cooperative transmission system drives the two cutting feed wheel sets to rotate in opposite directions, simultaneously cutting the upper and lower ends of the armor layer to create a gap between it and the wire core. At the same time, it drives the rocker arm to perform a circumferential rocker motion, thereby causing the stripping sleeve to move linearly along the cable direction, inserting into the gap between the armor layer and the wire core, and applying axial shearing impact force to the adhered part to achieve the separation of the armor layer and the wire core.

[0007] Furthermore, the cutting feed wheel assembly is horizontally positioned inside the mounting cover perpendicular to the cable movement direction. It includes a friction roller capable of contacting the inserted cable, a cutting blade fixed to the end face of the friction roller and capable of cutting the armor layer along the cable extension direction, and a rotating shaft coaxially fixed with the friction roller. The end of the rotating shaft is rotatably mounted on the side wall of the mounting cover and fixed to the corresponding first gear or second gear after passing through the mounting cover.

[0008] Furthermore, the mounting cover is provided with a wire sleeve for guiding the cable to be aligned and inserted along the gap area between the two cutting feed wheel sets. The top and bottom walls of the wire sleeve are provided with openings for the friction roller and the cutting blade to contact the cable when they rotate. An extension tube extends axially from the front end of the wire sleeve and is close to the guide rail.

[0009] Furthermore, the cooperative transmission system includes a first gear fixed to the shaft end of one cutting feed wheel set and a second gear fixed to the shaft end of another cutting feed wheel set and meshing with the first gear. The shaft ends of the two cutting feed wheel sets establish a coupling transmission with opposite directions through the first gear and the second gear, thereby pulling the cable forward. The cooperative transmission system also includes a driven wheel disk rotatably arranged between the mounting cover and the guide rail and meshing with the first gear or the second gear. The rotation of the driven wheel disk triggers the circumferential swing arm movement of the rocker arm.

[0010] Furthermore, the center of the driven wheel is rotatably mounted on a support via a central shaft. The support is fixed to the top wall of the machine tool to position the rotation of the driven wheel. A crank pin is fixed at the edge of the driven wheel away from the central shaft. The crank pin is rotatably connected to one end of a rocker arm, and the other end of the rocker arm extends toward the peeling sleeve and is rotatably set therewith.

[0011] Furthermore, the stripping sleeve includes a slider that can slide along a pre-set slide groove on the top wall of the guide rail. The top of the slider is fixed with a stripping ring that is coaxial with the cable and is used to perform secondary stripping of the armor layer and the part of the wire core that are bonded together. The bottom of the slider extends downward with a connecting arm. A drive pin is installed perpendicular to the direction of the connecting arm and moves through the through groove of the side wall of the guide rail. The drive pin is rotatably connected to the near end of the rocker arm. The stripping ring is set with a conical ring blade at one end of the cable being connected.

[0012] Furthermore, a shearing system is provided on the side of the stripping sleeve away from the mounting cover, located above the machine tool. It is linked with the stripping sleeve to cut the passing cable. The shearing system includes a pusher fixed to the drive pin and slidable axially along the top wall of the machine tool, a gantry installed above the machine tool for the pusher to slide through, and a shearing part located inside the gantry and capable of opening or closing the clamps under the push of the pusher.

[0013] Furthermore, the shearing unit includes two cross-opposing shearing arms, which are hinged in the mounting slot at the top of the gantry. When in the open clamping state, the two shearing arms open outwards, leaving a channel for the cable to pass through. At this time, the bottom ends of the shearing arms hang freely on the top wall of the machine tool. The shearing arm includes a hinge shaft rotatably mounted in the mounting slot. The bottom of the hinge shaft is fixed with a swing arm that hangs on the top wall of the machine tool without external force, so that the top of the hinge shaft is fixed with a shearing blade that opens outwards. The inner side of the shearing blade has a cutting edge.

[0014] Furthermore, the pushing part includes a push block, a slide bar fixed to the bottom of the push block and sliding along the top wall of the machine tool, and a connecting rod installed on the side wall of the push block and extending toward and fixed to the drive pin; the push block has a wedge-shaped inclined surface on the side near the mounting cover, and as it enters the inclined surface below the gantry, the height of the inclined surface gradually increases, and the swing arms on both sides are gradually spread apart, causing the shearing blades to rotate toward each other around the hinge axis and cross and overlap to cut the passing cable.

[0015] Furthermore, the swing arm is provided with an adjustment groove, and a sliding support foot is slidably connected in the adjustment groove; two guide protrusions extend upward from the two bottom corners along the inclined surface of the push block, gradually approaching the center line.

[0016] The technical effects and advantages of this invention are as follows:

[0017] By utilizing the opposing rotation of the upper and lower parts, the upper and lower ends of the armor layer are simultaneously cut off by the cable feeder, creating a gap between the armor layer and the wire core. During this process, the circular motion is converted into a reciprocating linear movement along the cable direction through a synchronously driven, coaxially aligned rotational transmission. This allows the armor layer to be inserted axially into the gap between the armor layer and the wire core, applying axial shearing impact force to the adhered parts. This achieves automatic separation of the armor layer and the wire core without manual pulling. Compared to static stripping tools, the dynamic motion provides an axial shearing effect, significantly improving stripping quality and efficiency. Simultaneously, the entire stripping process is coordinated with the continuous cable feed, resulting in a high degree of automation, reducing labor costs and operational intensity, and effectively solving the problems of reliance on manual pulling and insufficient stripping in existing technologies.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The cable stripping and recycling device involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Reference Figures 1 to 7As shown, this invention provides a cable stripping and recycling device, including a machine tool 1 and a cable slitting system located above it for axially cutting the armor layer along the surface of the cable. The cable slitting system includes a mounting cover 2 fixed to the top wall of the machine tool 1, and two cutting feed wheel sets 3 arranged vertically opposite each other and rotatably mounted inside the mounting cover 2. The two cutting feed wheel sets 3 rotate in opposite directions along the cable feeding direction to cut the armor layer of the cable inserted therein while applying axial thrust, controlling the cable to continuously feed forward to complete subsequent cutting. A cooperative transmission system for controlling the movement of the cable slitting system is provided on one side, in front of the mounting cover 2. A stripping sleeve 9 is provided, which is coaxial with the clamping area between the upper and lower cutting feed wheel sets 3. It slides linearly within the guide rail 10 fixed on the top wall of the machine tool 1. The cooperative transmission system is connected to the stripping sleeve 9 via the rocker arm 8. In the working state, the cooperative transmission system drives the two cutting feed wheel sets 3 to rotate in opposite directions, cutting the upper and lower ends of the armor layer simultaneously, creating a gap between it and the wire core. At the same time, it drives the rocker arm 8 to perform a circumferential rocker arm movement, so as to drive the stripping sleeve 9 to move linearly along the cable direction, insert it into the gap between the armor layer and the wire core, and apply axial shear impact force to the adhered part, thereby realizing the separation of the armor layer and the wire core.

[0034] The cooperative transmission system includes a first gear 4 fixed to the shaft end of one cutting feed wheel set 3 and a second gear 5 fixed to the shaft end of another cutting feed wheel set 3 and meshing with the first gear 4. The shaft ends of the two cutting feed wheel sets 3 establish a coupling transmission with opposite directions through the first gear 4 and the second gear 5, thereby pulling the cable forward. The cooperative transmission system also includes a driven wheel 7 rotatably arranged between the mounting cover 2 and the guide rail 10 and meshing with the first gear 4 or the second gear 5. The rotation of the driven wheel 7 triggers the circumferential swing arm movement of the rocker arm 8.

[0035] The machine tool 1 is also equipped with a drive device 6 for providing power to the cooperative transmission system; the drive device 6 includes a gearbox fixed above the machine tool 1 and a motor connected to the input end of the gearbox. The output power of the motor is transmitted to one side of the first gear 4 or the second gear 5 via the gearbox to provide a power source for the operation of the equipment.

[0036] The cutting feed wheel assembly 3 is horizontally positioned inside the mounting cover 2 perpendicular to the cable movement direction. It includes a friction roller 31 that can contact the inserted cable, a cutting blade 32 fixed to the end face of the friction roller 31 and capable of cutting the armor layer along the cable extension direction, and a rotating shaft 33 coaxially fixed with the friction roller 31. The end of the rotating shaft 33 is rotatably mounted on the side wall of the mounting cover 2 and fixed to the corresponding first gear 4 or second gear 5 after passing through the mounting cover 2. The cable armor layer is cut into by the rotating cutting blade 32 until the armor layer contacts the friction roller 31 and pulls the cable forward under the action of friction. The cutting blade 32 then cuts off the upper and lower ends of the armor layer simultaneously, so that a crack can be generated between the armor layer and the wire core, so that it can be loosened in an unconstrained state.

[0037] The mounting cover 2 is equipped with a wire sleeve 21 for guiding the cable to be inserted into the clamp area between the two cutting feed roller sets 3. The top and bottom walls of the wire sleeve 21 are provided with openings for the friction roller 31 and the cutting blade 32 to contact the cable when they rotate. An extension tube 22 extends axially from the front end of the wire sleeve 21 and is close to the guide rail 10. The cable that has completed the cutting step is continued to be conveyed forward along the extension tube 22 under the drive of the friction roller 31 and protrudes from the port of the extension tube 22 to compensate for the problem of the increased distance between the stripping sleeve 9 and the mounting cover 2 caused by the setting position of the driven wheel 7.

[0038] The inner diameter of the conductor sleeve 21 and the extension conduit 22 is adapted to the outer diameter of the cable, so that the armor layer cut by the cutting blade 32 is still wrapped around the surface of the wire core under the constraint of the tube wall when it does not protrude from the port of the extension conduit 22, so as to facilitate docking with the stripping sleeve 9 and performing a secondary stripping action.

[0039] The center of the driven wheel 7 is rotatably mounted on the support 72 via the central shaft 73. The support 72 is fixed to the top wall of the machine tool 1 to position the rotation of the driven wheel 7. A crank pin 71 is fixed at the edge of the driven wheel 7 away from the central shaft 73. The crank pin 71 is rotatably connected to one end of the rocker arm 8. The other end of the rocker arm 8 extends toward the stripping sleeve 9 and is rotatably set therewith. The driven wheel 7 rotates around the central shaft 73 with the crank pin 71 near its edge. The crank pin 71 pulls one end of the rocker arm 8 to swing circumferentially around the central shaft 73. Since the distance between the two ends of the rocker arm 8 is constant, the other end of the rocker arm 8 synchronously follows and pulls the stripping sleeve 9 to slide axially back and forth along the direction constrained by the guide rail 10. That is, the circumferential motion of the crank pin 71 is converted into the linear movement of the stripping sleeve 9 along the cable direction by the rocker arm 8. The top wall of the machine tool 1 is provided with a groove 15 for the driven wheel 7 and the rocker arm 8 to move, so as to ensure reasonable structural layout and reliable operation.

[0040] The stripping sleeve 9 includes a slider 93 that can slide along a pre-set slide groove 101 on the top wall of the guide rail 10. The top of the slider 93 is fixed with a stripping ring 91 that is coaxial with the cable and is used to perform secondary stripping of the armor layer and the core bonded portion. The bottom end of the slider 93 extends downward to the connecting arm 94. A drive pin 95 is installed perpendicular to the connecting arm 94 and moves through the through groove 102 on the side wall of the guide rail 10. The drive pin 95 is rotatably connected to the near end of the rocker arm 8. The stripping ring 91 is set with a conical ring blade at one end of the cable being connected. The stripping ring 91 can be inserted into the gap between the armor layer and the core along the surface of the core and peel off the bonded portion that is tangled with the core along the axial direction to achieve complete separation of the core wall. The stripping sleeve 9 may also include multiple cutting blades 92 that are radially fixed to the side wall of the stripping ring 91 for cutting the armor layer into multiple parts.

[0041] In order to continuously cut the stripped cables for recycling, refer to Figures 8 to 13 As shown, a shearing system is provided on the side of the stripping sleeve 9 away from the mounting cover 2, located above the machine tool 1. It is linked with the stripping sleeve 9 to cut the passing cable. The shearing system includes a pushing part 11 fixed to the drive pin 95 and slidable axially along the top wall of the machine tool 1, a gantry 12 installed above the machine tool 1 for the pushing part 11 to slide through, and a shearing part located inside the gantry 12 that can open or close the clamp under the push of the pushing part 11. The shearing part intermittently opens and closes the clamp to cut the passing cable into multiple small segments for easy recycling.

[0042] The shearing unit includes two cross-shaped shearing arms 13, which are hinged in the mounting groove 121 at the top of the gantry 12. When in the open clamping state, the two shearing arms 13 open outwards, leaving a channel for the cable to pass through. At this time, the bottom end of the shearing arm 13 hangs freely on the top wall of the machine tool 1. The shearing arm 13 includes a hinge shaft 131 rotatably mounted in the mounting groove 121. The bottom of the hinge shaft 131 is fixed with a swing arm 133 that hangs on the top wall of the machine tool 1 without external force, so that the top of the hinge shaft 131 is fixed with a shearing blade 132 that opens outwards. The inner side of the shearing blade 132 has a cutting edge. When the swing arms 133 on both sides rotate outwards about the hinge shaft, the shearing blade 132 on the corresponding side rotates towards the side closer to the central axis. The two cross and overlap to cut the passing wire core and the stripped armor layer.

[0043] The pushing unit 11 includes a push block 111, a slide bar 113 fixed to the bottom of the push block 111 and sliding along the top wall of the machine tool 1, and a connecting rod 112 installed on the side wall of the push block 111 and extending toward and fixed to the drive pin 95. The push block 111 has a wedge-shaped inclined surface on the side near the mounting cover 2. As it enters the inclined surface below the gantry 12, the height of the inclined surface gradually increases, and the swing arms 133 on both sides are gradually spread apart, causing the shearing blades 132 to rotate toward each other around the hinge axis and cross and overlap to cut the passing cable. The edges at the top of the left and right sides of the push block 111 are inclined inward and retracted to avoid interference with the swing arms 133 during the process of being smoothly supported by the inclined surface.

[0044] As the height of the push block 111 changes as it enters the inclined plane below the gantry 12, the point of contact between it and the swing arm 133 changes. Therefore, the swing arm 133 and the push block 111 are optimized and adjusted: an adjustment groove 1331 is provided in the swing arm 133, and a sliding support foot 134 is slidably connected in the adjustment groove 1331; two guide protrusions 114 extend upward from the two bottom corners along the inclined plane of the push block 111 and gradually approach the center line; the sliding support foot 134 is guided by the guide protrusions 114 as it rises along the inclined plane and automatically adjusts its sliding position in the adjustment groove 1331 to adapt to the change in the fulcrum position between the swing arm 133 and the push block 111 as the swing arm 133 gradually opens.

[0045] The sliding support 134 includes a sliding member 1341 that is slidably engaged in the adjusting groove 1331, and a connecting block 1342 that rotates at the bottom end of the sliding member 1341 via a pin 1343, so that the connecting block 1342 can be kept vertically downward under the action of gravity. The bottom end of the connecting block 1342 is coaxially rotatably connected to a steering member 1344, which is used to continuously correct the direction of the roller 1345 moving along the guide ridge 114. A roller 1345 that can contact the inclined surface is rotatably installed in the steering member 1344.

[0046] To prevent the shearing part from blocking and interfering with the continuous feed of the cable at the moment of clamping, an elastic retraction mechanism is provided at the bottom of the gantry 12 in the groove 15. This allows the gantry 12 to adaptively retract outward under the push of the subsequent feed cable when the clamp is closed to cut the cable, and to push the gantry 12 back to its original position when the cable is no longer obstructed after the clamp is opened. The elastic retraction mechanism includes a baffle 16 fixed to the side wall of the groove 15 and a spring 14 connected between the gantry 12 and the baffle 16. The bottom end of the gantry 12 slides in the side wall of the groove 15, allowing it to move elastically within a certain range.

[0047] Working principle of this invention:

[0048] After the equipment is started, the output power of the motor is transmitted to the shaft end of the lower cutting feed wheel set 3 through the gearbox. The shaft ends of the upper and lower opposing cutting feed wheel sets 3 are coupled in opposite directions through the first gear 4 and the second gear 5, so that the two cutting feed wheel sets 3 rotate in opposite directions along the wire feeding direction. The operator aligns the cable to be processed with the wire sleeve 21 and inserts it into one side of the upper and lower opposing cutting feed wheel sets 3 and applies a certain axial thrust, so that the inlet end of the cable armor layer is cut by the rotating cutting blade 32 until the armor layer contacts the friction roller 31 and pulls the cable forward under the action of friction. The cutting blade 32 then cuts the upper and lower ends of the armor layer simultaneously, causing the armor layer and the wire core to crack and loosen. The cable that has completed the cutting step continues to be conveyed forward along the extension guide tube 22 under the drive of the friction roller 31 and protrudes from the port of the extension guide tube 22. At this time, the armor layer loses the constraint of the tube wall and a gap is generated between it and the wire core under its own tension.

[0049] Simultaneously, the first gear 4 synchronously drives the driven wheel 7 to rotate. The driven wheel 7 then rotates around the central axis 73, carrying the crank pin 71 near its edge. The crank pin 71 pulls one end of the rocker arm 8 to oscillate around the central axis 73. Since the distance between the two ends of the rocker arm 8 is constant, the other end of the rocker arm 8 synchronously follows and pulls the stripping sleeve 9 to slide axially back and forth along the direction constrained by the guide rail 10. This converts the circular motion of the crank pin 71 into linear movement of the stripping sleeve 9 along the cable direction via the rocker arm 8. Because the cable has a certain degree of flexibility, after extending a certain length beyond the port of the extension conduit 22, its free end droops due to gravity. At this time, the operator needs to use an auxiliary device to... Using a tool such as clamps, align the free end of the wire core with the stripping ring 91 until the wire core extends beyond the maximum retraction range of the stripping sleeve 9. Release the tool to prevent subsequent wire cores from detaching from the tube due to the retraction of the stripping ring 91. As the stripping sleeve 9 reciprocates along the cable direction, the stripping ring 91 can insert into the gap between the armor layer and the wire core along the wire core surface, axially peeling away the adhesive portion that is connected to the wire core, achieving complete separation of the core wall. When the dynamically moving stripping ring 91 retracts and accumulates power in each round before moving towards the direction of the feed cable, it applies an axial shearing impact force between the armor layer and the wire core. Compared to a static stripping tool structure, it has an axial shearing effect, further improving the stripping effect.

[0050] At the same time, the drive pin 95 pulls the pusher 11 to move backward in the axial direction. When the push block 111 has not contacted the bottom end of the two cross-hinged shearing arms 13, the free ends of the two swing arms 133 fall freely under the influence of gravity until the sliding support 134 contacts the table of the machine tool 1 and is supported. The corresponding shearing blades 132 deviate away from the central axis, leaving a channel between the cross-opposed shearing blades 132 for the stripped cable to pass through, that is, the shearing part is in the open clamp state. When the push block 111 moves closer to the stripping sleeve 9, the bottom edge of the inclined surface of the push block 111 contacts the sliding support 134 first, and as it enters... As the slope below the gantry 12 gradually increases in height, the sliding feet 134 on both sides are gradually raised. During this process, the sliding feet 134 automatically adjust their sliding position in the adjusting groove 1331 under the guidance of the guide convex strip 114 as they rise along the slope. This adapts to the change in the fulcrum position between the swing arm 133 and the push block 111 as the swing arm 133 gradually expands. This smoothly pushes the swing arms 133 on both sides to rotate outward around the hinge axis, expanding them. This causes the shearing blade 132 on the corresponding side to rotate towards the side closer to the central axis. Through the cross-over overlap of the two blades, the penetrating wire core and the stripped armor layer are cut into several small sections that are easy to recycle, transport, or use.

[0051] The above description is merely 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 technical scope disclosed in the present invention, in accordance with the technical plan and improved concept of the present invention, should be included under the protection of the present invention.
