Description

Technical Field

[0001] This invention belongs to the field of cable recycling technology, specifically referring to a waste cable recycling device. Background Technology

[0002] With the rapid development of modern power networks and communication engineering, the number of waste cables generated annually due to aging lines and upgrades is increasing exponentially. Waste cables contain large amounts of high-quality copper, aluminum, and other metallic conductive cores, as well as polymer insulation materials such as polyvinyl chloride and cross-linked polyethylene. Therefore, efficient resource recycling of waste cables is necessary.

[0003] In the recycling process of waste cables, especially for medium to large diameter cables (such as reels of power cables or long-distance communication cables), the core initial pre-processing step is the stripping process, which involves mechanically breaking the outer insulation sheath to physically separate the insulation layer from the internal conductive metal core. Simultaneously, to meet subsequent requirements for metering, crushing, packaging, or transportation, segmenting and cutting long-distance or reeled waste cables to a fixed length is essential. However, existing cable recycling equipment has significant technical deficiencies in the coordination of the stripping and cutting processes when processing medium to large long cables, specifically in the following two aspects: Firstly, the process of "cutting into sections first, then stripping" is employed: For long or coiled medium-to-large cables, they are first cut into several independent short sections by a cutting mechanism, and then these short sections are fed one by one into a stripping machine to strip the insulation layer. This processing method disrupts the original continuity of the long cable, making it impossible to achieve continuous feeding in the stripping process. Operators or automated robotic arms must frequently and repeatedly perform cable loading and alignment actions, resulting in high labor intensity, extremely low production efficiency, and a high risk of stripping failure due to deviations in the feeding posture.

[0004] Secondly, the "stripping first, then cutting" process, while ensuring continuous feeding during stripping, results in the cable losing its original structural constraints and radial fastening force after the outer insulation sheath is cut open and substantially separated from the inner metal core. If the insulation and metal core are then cut simultaneously while still separated, the significant difference in yield strength and shear resistance between the two materials makes them prone to relative slippage, disarray, and structural instability under the shear stress of the cutter. This prevents the cutter from completely, accurately, and smoothly cutting the insulation and copper core simultaneously on the same cross-section, often resulting in severe burrs on the metal core cut, tearing of the insulation, and even blade chipping. Summary of the Invention

[0005] To address the above issues, this invention provides a waste cable recycling device. A servo motor drives a pressure roller to feed the cable, which is then stripped by a cutter head. A first telescopic cylinder drives a magnetic pressure following mechanism to approach the cable, using magnetic repulsion to press the arc-shaped pressure plate against the cable. The mechanism then moves forward to the front of the cutter head. After a distance sensor is triggered, the motor stops, and a circular saw cuts the cable between the pressure plate and the cutter head. The process then resets and repeats. This invention achieves a synergy between continuous stripping and smooth cutting, avoiding messy cuts, and allows for stepless adjustment of the cutting length.

[0006] The technical solution adopted by this invention is as follows: This invention proposes a waste cable recycling device, including a mounting frame. A lower platform and an upper platform are installed on the mounting frame from bottom to top. Both the lower platform and the upper platform have openings in the middle to provide space for unloading and cutting, respectively. The lower platform has multiple guides in the middle to guide the cable forward. Magnetic pressure following and binding mechanisms are symmetrically arranged on both sides of the cable on the lower platform. The magnetic pressure following and binding mechanism has a first telescopic cylinder on the side opposite to the cable and is connected to the mounting frame to drive the magnetic pressure following and binding mechanism to move closer to and away from the cable.

[0007] Furthermore, the cable is provided with stripping mechanisms on both the upper and lower sides, the upper platform is provided with a cutting mechanism for cutting the cable downwards, and the magnetic pressure following binding mechanism is provided with a reset mechanism.

[0008] Furthermore, the magnetic pressure following restraint mechanism includes a housing that slides and engages with the lower platform. The housing is provided with a translation member. Guide rods parallel to the cable axis slide through both ends of the translation member, and a pressure rod perpendicular to the cable axis slides through the middle of the translation member.

[0009] Furthermore, the guide rod is fixedly connected to the housing, the housing has a channel on the side facing the cable, one end of the pressure rod passes through the channel and is detachably connected to an arc-shaped pressure plate pointing towards the cable, the other end of the pressure rod is fixed with a magnetic block, and a magnetic strip is fixed on the inner wall of the housing away from the cable, the magnetic block and the magnetic strip are parallel and their opposite surfaces are in a state of like repulsion.

[0010] Furthermore, the reset mechanism includes a reset rod disposed on the translation member on the side opposite to the direction of cable travel. The reset rod is parallel to the guide rod and penetrates the housing. A first spring is sleeved on the reset rod, with the two ends of the first spring abutting against the outer end of the reset rod and the housing, respectively. A second spring is sleeved on the pressure rod, with the two ends of the second spring abutting against the translation member and the magnetic block, respectively.

[0011] Furthermore, a distance measuring sensor is installed on the translation component, and the detection end of the distance measuring sensor faces the inner wall of the housing in the direction of cable travel.

[0012] Furthermore, the stripping mechanism includes two sets of cutter discs and pressure rollers located on the upper and lower sides of the cable. Each set of pressure rollers is coaxially arranged on both sides of the corresponding cutter disc. The diameter of the cutter disc is larger than the diameter of the pressure roller. The wheel surface of the pressure roller is used to press and drive the surface of the cable insulation layer. The cutting edge of the cutter disc is used to cut through the cable insulation layer. It also includes two sets of synchronously running servo motors located on the lower platform and the upper platform for driving the pressure roller to rotate.

[0013] Furthermore, the cutting mechanism includes a gantry fixed to the upper platform, a second telescopic cylinder installed vertically downward on the gantry, and a circular saw driven to rise and fall by the second telescopic cylinder, the circular saw being directly opposite the cable.

[0014] Furthermore, the height of the arc-shaped pressure plates on both sides of the cable avoids the pressure rollers on the upper and lower sides, and the arc-shaped pressure plates do not spatially interfere with the pressure rollers when they close inward to press the cable.

[0015] Furthermore, when the direction of cable travel is considered forward, the initial pressing position of the arc-shaped pressure plate is located behind the cutter head, the final pressing position of the arc-shaped pressure plate is located in front of the cutter head, and the cutting trajectory of the circular saw is located between the final pressing position of the arc-shaped pressure plate and the cutter head.

[0016] Furthermore, the concave surface of the arc-shaped pressure plate is adapted to the side of the cable, and the concave surface of the arc-shaped pressure plate is uniformly distributed with protrusions for increasing friction.

[0017] Furthermore, firstly, the servo motor is started to drive the pressure roller to squeeze and push the cable forward for stripping. After the servo motor has been running for a preset time, the first telescopic cylinder is started to extend, so that the arc-shaped pressure plate presses the cable behind the cutter head and moves forward synchronously with the cable. When the distance detected by the distance sensor is less than a preset threshold, the arc-shaped pressure plate moves to the front of the cutter head, the servo motor is turned off, and the second telescopic cylinder is started to extend and drive the circular saw to cut the cable. Then, the second telescopic cylinder and the first telescopic cylinder are retracted in sequence to release the restraint on the cut cable. The arc-shaped pressure plate is then reset, and the servo motor is started again to strip the cable, thus forming a cyclic operation.

[0018] The beneficial effects achieved by the present invention using the above structure are as follows: (1) The present invention achieves continuous feeding and stripping of cables by driving the pressure roller with a servo motor. Before the cutting action occurs, the cable is pressed in advance behind the cutter head by an arc-shaped pressure plate and moves synchronously through the cutter head to the front of the cutter head by relying on friction. When the circular saw falls to cut, one end of the cutting surface is pressed tightly by the pressure roller, and the other end is firmly wrapped by the arc-shaped pressure plate. This method makes the insulation layer and metal core, which originally lost radial fastening force due to stripping, still have strong structural constraints. This avoids the relative slippage and structural instability of the insulation layer and metal core under the action of circular saw shear stress, and ensures that the circular saw can cut the two smoothly and synchronously on the same cross section. It effectively eliminates problems such as burrs on the cut, tearing of the insulation layer and chipping of the cutter. While ensuring high efficiency of continuous feeding, it achieves extremely high cutting quality.

[0019] (2) The first telescopic cylinder drives the housing to approach the cable. The magnetic strip on the inner wall of the housing and the magnetic block at the end of the pressure rod approach each other to generate a huge non-contact magnetic repulsion force. This magnetic repulsion force is directly converted into a strong radial pressure of the arc-shaped pressure plate on the cable, thereby generating sufficient static friction between the two. Since the magnetic force transmission is completely non-contact, in the direction of the cable's axial movement, the translation component only needs to overcome the very small sliding friction force on the guide rod, and does not need to bear the huge mechanical friction resistance brought about by the radial pressure. This allows the cable to drive the arc-shaped pressure plate to move forward synchronously and smoothly without any effort, realizing the coordination of radial pressure force and axial following movement, ensuring the extremely smooth and reliable operation of the mechanism.

[0020] (3) Since the speed at which the servo motor drives the pressure roller to advance the cable is constant and precisely controllable, the operator only needs to adjust the time interval between the two actions of "servo motor start feeding" and "first telescopic cylinder start clamping" in the control system to precisely change the length of the cable released before each arc-shaped pressure plate clamps. This design can achieve precise and stepless adjustment of the cutting length through pure program timing control, which greatly improves the flexible production capability of the equipment and can quickly and perfectly adapt to the diverse needs of different subsequent processing steps for cable segment length.

[0032] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0033] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, this invention proposes a waste cable recycling device. Its overall basic structure includes a mounting frame 1. A lower platform 11 and an upper platform 12 are stably installed on the mounting frame 1 from bottom to top. In order to meet the space requirements of waste cables during processing, an opening 13 is provided in the middle of both the lower platform 11 and the upper platform 12. The opening 13 of the upper platform 12 provides clearance for the cutting process, while the opening 13 of the lower platform 11 forms the unloading outlet for the cut material. Multiple guides 14 are arranged in the middle of the lower platform 11 along the cable feeding path. The arrangement of the guides 14 can effectively constrain the initial posture of the cable and guide the cable to move forward smoothly.

[0035] To achieve continuous cutting of the cable insulation layer, stripping mechanisms 4 are symmetrically arranged on the upper and lower sides of the cable. The stripping mechanism 4 includes two sets of cutter discs 41 and pressure rollers 42. Each set of pressure rollers 42 is coaxially arranged on both sides of the corresponding cutter disc 41. In terms of size design, the diameter of the cutter disc 41 is larger than the diameter of the pressure roller 42. In actual operation, the wheel surface of the pressure roller 42 is responsible for tightly pressing the surface of the cable insulation layer, providing stable radial constraint; while the cutting edge of the larger diameter cutter disc 41 can accurately cut through the cable insulation layer. Two sets of synchronously running servo motors 43 are fixedly installed on the lower platform 11 and the upper platform 12. The servo motors 43 are used to drive the pressure rollers 42 to rotate, and then rely on the friction between the pressure rollers 42 and the cable to squeeze and pull the cable forward, so as to realize the synchronous feeding and stripping.

[0036] A cutting mechanism 5 for cutting cables downwards is also provided on the upper platform 12. The cutting mechanism 5 includes a gantry frame 53 fixed on the upper platform 12. A second telescopic cylinder 52 is vertically installed on the gantry frame 53. The output end of the second telescopic cylinder 52 is connected to a circular saw 51 facing the cable. Driven by the second telescopic cylinder 52, the circular saw 51 can perform lifting and lowering actions, thereby cutting the cable passing below to a fixed length.

[0037] The core of this invention lies in the fact that two magnetic pressure following and binding mechanisms 2 are symmetrically arranged on both sides of the cable on the lower platform 11. Each magnetic pressure following and binding mechanism 2 is provided with a first telescopic cylinder 3 on the side facing away from the cable. The tail end of the first telescopic cylinder 3 is connected to the mounting frame 1, and its output end is used to drive the magnetic pressure following and binding mechanism 2 to move closer to or away from the cable.

[0038] Specifically, the magnetic pressure following restraint mechanism 2 includes a housing 21 that slides onto the lower platform 11. The housing 21 can move laterally under the push and pull of the first telescopic cylinder 3. A translation member 25 is provided inside the housing 21. Two guide rods 23 parallel to the cable axis slide through both ends of the translation member 25. The guide rods 23 are fixedly connected to the housing 21, which allows the translation member 25 to slide along the length of the cable. At the same time, a pressure rod 26 perpendicular to the cable axis slides through the middle of the translation member 25.

[0039] The housing 21 has a channel 22 on the side facing the cable. One end of the pressure rod 26 passes through the channel 22 and is connected to an arc-shaped pressure plate 27 pointing towards the cable. Preferably, the arc-shaped pressure plate 27 and the pressure rod 26 are connected by a threaded connection or other detachable method, so as to replace the appropriate arc-shaped pressure plate 27 according to the waste cable of different diameter. The concave shape of the arc-shaped pressure plate 27 is adapted to the side of the cable, and the concave surface is evenly distributed with protrusions 29. The function of the protrusions 29 is to significantly increase the static friction between the arc-shaped pressure plate 27 and the cable surface, so as to ensure the reliability of the following action. A magnetic block 28 is fixed at the other end of the pressure rod 26 away from the cable, and a magnetic strip 24 is fixed on the inner wall of the housing 21 away from the cable. The magnetic block 28 and the magnetic strip 24 are arranged in parallel. The magnetic strip 24 covers the movement range of the magnetic block 28, and the opposite surfaces of the two are in a state of like repulsion.

[0040] The magnetic pressure following restraint mechanism 2 is also equipped with a reset mechanism 6. The reset mechanism 6 includes a reset rod 61 disposed on the translation member 25 and located on the side opposite to the cable forward direction. The reset rod 61 is parallel to the guide rod 23 and passes through the housing 21. A first spring 62 is sleeved on the reset rod 61, and the two ends of the first spring 62 abut against the outer end of the reset rod 61 and the outer wall of the housing 21, respectively. A second spring 63 is sleeved on the pressure rod 26, and the two ends of the second spring 63 abut against the translation member 25 and the magnetic block 28, respectively. In addition, a distance sensor 7 is installed on the translation member 25. The detection end of the distance sensor 7 faces the inner wall of the housing 21 in the cable forward direction and is used to monitor the displacement of the translation member 25 in the housing 21 in real time.

[0041] In terms of spatial layout, the height of the arc-shaped pressure plates 27 on both sides cleverly avoids the pressure rollers 42 on the upper and lower sides, ensuring that the arc-shaped pressure plates 27 will not interfere with the pressure rollers 42 when they close inward to press the cable. With the direction of cable movement as the front, the initial pressing position of the arc-shaped pressure plates 27 is located behind the cutter head 41 (i.e., the unstripped side). As the cable moves forward, the final pressing position of the arc-shaped pressure plates 27 will move to the front of the cutter head 41 (i.e., the stripped side). The cutting trajectory of the circular saw 51 is precisely set between the final pressing position of the arc-shaped pressure plates 27 and the cutter head 41.

[0042] The mechanical transmission principle of the magnetic pressure following restraint mechanism 2 in this device is as follows: When the arc-shaped pressure plate 27 needs to press the cable and move forward synchronously by relying on friction, a huge radial pressure must be applied. If a traditional rigid mechanical push is used, a huge sliding friction will be generated between the pressure component and the translation component. According to the interaction of forces, it is extremely difficult for the translation component 25 to be driven by the cable. This invention innovatively introduces a magnetic repulsion mechanism. When the first telescopic cylinder 3 pushes the housing 21 close to the cable, the magnetic strip 24 closes to the magnetic block 28. The closer the distance, the greater the repulsion. This non-contact magnetic repulsion is converted into a huge pressing force of the pressure rod 26 on the cable. In the direction of cable movement, the translation component 25 only needs to overcome the tiny sliding friction on the guide rod 23, without having to overcome the frictional resistance caused by radial pressure. Therefore, the cable can drive the arc-shaped pressure plate 27 and the translation component 25 to move synchronously by surface friction.

[0043] The specific work process is as follows: Initial loading and debugging stage: Manually guide the waste cable to below the pressure roller 42, start the cutting mechanism 5 for initial calibration, and stop when the cut end of the cable is in the same vertical position as the circular saw 51. At this time, the other mechanisms in the device are in the reset and separation state. This initial state is equivalent to the period after the circular saw 51 cuts the cable and the first telescopic cylinder 3 retracts and the front section of the cable falls off during continuous operation. After the debugging is completed, the automated continuous operation can be carried out according to the preset process sequence.

[0044] In continuous cyclic operation: First, the servo motor 43 is started, driving the pressure roller 42 to squeeze and pull the cable forward. At the same time, the cutter head 41 continuously strips the cable. After the servo motor 43 has been running for a preset time, the first telescopic cylinder 3 is started to extend. The first telescopic cylinder 3 drives the housing 21 to move. Through the repulsive force between the magnetic strip 24 and the magnetic block 28, the arc-shaped pressure plate 27 tightly presses the cable behind the cutter head 41. As the cable continues to move forward, the pressed part passes through the cutter head 41 and is cut open. Due to the strong restraint of the arc-shaped pressure plate 27, the cable relies on static friction to drive the arc-shaped pressure plate 27 and the translation component 25 to overcome the elastic force of the first spring 62 and move forward synchronously. Although the insulation layer of the cable has been cut after passing the cutter head 41, the cut insulation layer and metal core will not be scattered due to the wrapping and restraint of the arc-shaped pressure plate 27.

[0045] When the translation component 25 moves forward, causing the distance sensor 7 to detect that the distance between it and the inner wall of the front side of the housing 21 is less than a preset threshold, it indicates that the arc-shaped pressure plate 27 has moved to the front of the cutter head 41. At this time, the system controls the servo motor 43 to turn off, the cable stops moving, and the end of the stripped cable is tightened by the arc-shaped pressure plate 27, while its rear is pressed by the pressure roller 42. The double fixation at both ends makes the cable form an extremely stable cutting surface at the cutting trajectory of the circular saw 51. Then, the control system starts the extension of the second telescopic cylinder 52, driving the circular saw 51 to smoothly cut the cable between the arc-shaped pressure plate 27 and the cutter head 41. After the cutting is completed, the second telescopic cylinder 52 first... The retraction of the circular saw 51 resets; then the first telescopic cylinder 3 retracts, moving the housing 21 away from the cable. As the magnetic strip 24 moves away, the magnetic repulsion decreases, and the second spring 63 pushes the magnetic block 28 and the pressure rod 26 back. The arc-shaped pressure plate 27 separates from the cable. At the moment the restraint disappears, the cut cable falls from the opening 13 of the lower platform 11 to be collected below. At the same time, the translation component 25, which is no longer restrained by the friction of the cable, instantly moves the arc-shaped pressure plate 27 back to the initial position behind the cutter head 41 under the reset pull of the first spring 62. Then the servo motor 43 starts again to peel and feed, starting the next working cycle.

[0046] Cable segment length adjustment: It is worth mentioning that the present invention can also adjust the segment length very conveniently. Since the speed at which the servo motor 43 drives the cable forward is constant, the length of the cable released before being clamped by the arc-shaped pressure plate 27 can be changed by simply adjusting the time interval between "servo motor 43 starts" and "first telescopic cylinder 3 starts clamping" in the control system, thereby achieving precise and stepless adjustment of the length of the cable segment cut each time.

When the distance detected by the distance sensor (7) is less than the preset threshold, the arc-shaped pressure plate (27) moves to the front of the cutter head (41), and the servo motor (43) is turned off. At this time, the second telescopic cylinder (52) is started to extend and drive the circular saw (51) to cut the cable. Then, the second telescopic cylinder (52) and the first telescopic cylinder (3) are retracted in sequence to release the restraint on the cut cable. Then the arc-shaped pressure plate (27) is reset, and the servo motor (43) is started again to strip the cable, thus forming a cycle operation.
