Description

Technical Field

[0001] This utility model belongs to the field of copper core recycling technology, and specifically relates to a peeling device for recycling waste copper cores. Background Technology

[0002] Against the backdrop of resource recycling and environmental protection policies, the recycling and processing of waste wires and cables has become an important resource regeneration pathway. Copper cores, as a high-value precious metal, not only reduce resource waste through efficient recycling but also bring significant economic benefits to individuals, households, and small recycling workshops. For small-batch waste wire recycling scenarios (such as idle household wires, leftover short wires from renovations, and wires from dismantled small electronic devices), various household-grade small wire strippers have emerged in the market. These devices are widely used due to their compact size, simple structure, low investment cost, and portability.

[0003] However, existing household-use small-scale wire strippers have significant functional limitations in practical use, making it difficult to meet the core requirement of efficient recycling. These devices typically work by using blades or rollers to make circular cuts or axial incisions in the wire insulation layer, only achieving surface damage and failing to automatically separate the insulation layer from the copper core. The subsequent insulation stripping process still relies on manual operation; operators must manually tear and peel the cut insulation layer from the copper core surface, which is not only labor-intensive but also extremely inefficient, making it unsuitable for small-scale recycling needs.

[0004] Meanwhile, manual stripping is difficult to control the force applied, and improper operation can easily cause scratches, deformation, or even breakage of the copper core surface, directly reducing the purity and value of the copper core for recycling. Furthermore, the edges of the cut insulation layer are sharp, which can easily cut hands during manual stripping, posing a serious operational safety hazard. The consistency of manual separation is poor, and some insulation layer remains on the surface of the copper core, which is difficult to completely remove. This requires additional time for cleaning, further increasing recycling costs and affecting the secondary utilization of the copper core. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a peeling device for recycling waste copper cores.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a peeling device for recycling waste copper cores, comprising two supports arranged symmetrically, with a guide roller between the two supports. A collar is provided on one side of the guide roller, and a through hole is provided on the inner side of the collar. Both ends of the through hole are formed with transition edges. A support is provided between the two supports, and a rotating ring is provided on the inner side of the support. A cutting element is rotatably sleeved at the center of the surface of the rotating ring. A screw is coaxially inserted into the inner side of the rotating ring, and both ends of the screw penetrate into the inner side of the support.

[0007] Preferably, a rotating rod is coaxially fixedly inserted into the inner side of the guide roller, and both ends of the rotating rod pass through the bracket and are rotatably connected to the bracket. A crank handle located on one side of the bracket is snapped onto one end of the rotating rod.

[0008] Preferably, the support has insertion holes on both sides, and the insertion holes are used to insert and cooperate with the screw. The bracket has a longitudinal groove on the inner side, and the longitudinal groove is used to move and pass through the screw.

[0009] Preferably, the surface of the screw is threaded with fastening nuts located at both ends of the rotating ring, and one side of the support is provided with fastening bolts arranged symmetrically. The inner side of the support is provided with mounting holes that are threadedly engaged with the fastening bolts. The mounting holes are connected to the insertion holes, and one end of the fastening bolt is in contact with the surface of the screw.

[0010] Preferably, a screw rod two is rotatably connected to the side of the support away from the cutting part, the surface of the screw rod two is threaded with a threaded part, and a knob is snapped onto the end of the screw rod two away from the support. A horizontal plate is fixedly sleeved on the surface of the threaded part, and the horizontal plate is snapped onto the bracket.

[0011] Preferably, a supporting cutting ring is provided on one side of the cutting member, and a polished surface is formed on the outer surface of the supporting cutting ring near the end of the cutting member.

[0012] Preferably, the end of the supporting cutting ring away from the cutting member is integrally formed with a middle part, and both ends of the middle part are formed with symmetrically arranged inclined surfaces. The end of the middle part away from the supporting cutting ring is integrally formed with a guide ring, and both ends of the guide ring are designed with an outward arc shape.

[0013] Preferably, the outer surface of the support ring is fitted with symmetrically arranged support rods, and one end of the support rod and the surface of the rotating ring are fitted with mounting plates, and the mounting plates are fastened to the bracket by bolts.

[0014] In summary, this utility model has the following beneficial effects: 1. This wire stripping device achieves automatic separation of the copper core and insulation layer through the coordinated action of the support cutting ring and the progressive movement of the wire during the wire stripping process. Its overall structural design is simple and compact, eliminating the need for complex transmission components and effectively reducing the equipment investment cost for waste copper core recycling. Simultaneously, the stable operation of the device relies on the coordinated action of multiple components, including the collar, guide roller, cutting element, and support cutting ring. Compared to existing technologies that only cut the insulation layer and require subsequent manual stripping, this significantly reduces reliance on manual operation, avoiding the inefficiencies and high labor intensity associated with manual separation. While ensuring the stripping effect, it achieves precise control of recycling costs, balancing economic efficiency and practicality. 2. As the guide rollers continuously rotate, the wire continues to advance. The end of the support cutting ring facing the cutting element has a sharp cutting surface, providing reliable protection for the insulation layer cutting. As the wire steadily advances along the preset path, the rigid support of the wire itself, combined with the sharp cutting surface of the support cutting ring, automatically completes the separation of the insulation layer from the copper core. Simultaneously, any remaining insulation layer on the wire surface is guided outwards through the inclined surface of the middle component. Furthermore, the guide ring's two ends feature an outer arc structure design, ensuring smooth guidance of the wire, preventing deviation during transport, and confining the stripped insulation layer within its outer arc, achieving complete separation of the insulation layer from the copper core. This design not only improves the cleanliness of the cutting and separation process but also facilitates the operator's separate collection of the copper core and individual processing of the insulation layer, ensuring the standardization and efficiency of the recycling process. 3. During the use of the cutting component, its rotating ring is positioned in a preset position between two fastening nuts. By symmetrically tightening the fastening nuts on both sides of the rotating ring, the threaded locking force forms an axial limit, firmly locking the rotating ring onto the surface of the screw rod, preventing axial movement during subsequent use. During installation, the fastening bolt passes through the mounting hole on the support and is screwed in until the end of the fastening bolt tightly abuts against the surface of the screw rod. The radial tightening force achieves radial limitation and circumferential fixation of the screw rod inside the support, ultimately completing the reliable assembly of the three components. This method facilitates the long-term use of the device. Attached Figure Description

Detailed Implementation

[0017] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0018] The specific embodiments of this utility model are described below with reference to the accompanying drawings: Example

[0019] refer to Figures 1-7 A stripping device for recycling waste copper cores includes two supports 100 arranged symmetrically. A guide roller 101 is provided between the two supports 100. A collar 200 is provided on one side of the guide roller 101. A through hole 201 is provided on the inner side of the collar 200. Transition edges 202 are formed at both ends of the through hole 201. A support 400 is provided between the two supports 100. A rotating ring 402 is provided on the inner side of the support 400. A cutting element 403 is rotatably sleeved at the center of the surface of the rotating ring 402. A screw 401 is coaxially inserted into the inner side of the rotating ring 402. Both ends of the screw 401 penetrate into the inner side of the support 400.

[0020] Specifically, during the wire stripping process, this stripping device achieves automatic separation of the copper core and insulation layer through the coordinated action of the supporting cutting ring 800 and the progressive movement of the wire. Its overall structural design is simple and compact, eliminating the need for complex transmission components and effectively reducing the equipment investment cost for waste copper core recycling. Simultaneously, the stable operation of the device relies on the coordinated action of multiple components, including the collar 200, guide roller 101, cutting component 403, and supporting cutting ring 800. Compared to existing technologies that only cut the insulation layer and require subsequent manual stripping, this significantly reduces reliance on manual operation, avoiding the inefficiencies and high labor intensity associated with manual separation. While ensuring the stripping effect, it achieves precise control of recycling costs, balancing economic efficiency and practicality. A rotating rod 102 is coaxially fixedly inserted into the inner side of the guide roller 101, and both ends of the rotating rod 102 pass through the bracket 100 and are rotatably connected to the bracket 100. A crank 103 located on one side of the bracket 100 is snapped onto one end of the rotating rod 102.

[0021] Specifically, the guide roller 101 adopts an arc-shaped roller surface adapted to the outer diameter of the wire to guide and constrain the wire's posture. During operation, the operator rotates the crank handle 103, which drives the rotating rod 102 and the guide roller 101 to rotate. With the help of the friction between the guide roller 101 and the surface of the wire, the wire is driven to move smoothly along the preset conveying path, providing stable preconditions for the subsequent insulation layer cutting process.

[0022] The support 400 has insertion holes 500 on both sides, and the insertion holes 500 are used to insert and cooperate with the screw 401. The bracket 100 has a longitudinal groove 503 on the inner side, and the longitudinal groove 503 is used to move and pass through the screw 401. The screw 401 has a threaded connection to a fastening nut 404 located at both ends of the rotating ring 402. The support 400 has a symmetrically arranged fastening bolt 501 on one side, and the support 400 has a mounting hole 502 that is threaded to the fastening bolt 501 on the inner side. The mounting hole 502 is connected to the insertion hole 500, and one end of the fastening bolt 501 is in contact with the surface of the screw 401.

[0023] Specifically, to ensure reliable assembly of the screw 401, rotating ring 402, and support 400, the screw 401 is first inserted into the insertion hole 500 of the support 400 along the pre-set longitudinal groove 503 on the bracket 100, so that part of the screw 401 extends into the inside of the support 400, leaving an exposed section to meet subsequent assembly requirements. Then, the fastening nuts 404 and rotating ring 402 are sequentially fitted onto the surface of the screw 401, ensuring that the rotating ring 402 is in a pre-set position between the two fastening nuts 404. By symmetrically tightening the fastening nuts 404 on both sides of the rotating ring 402, the threaded locking force forms an axial limit, firmly locking the rotating ring 402 onto the surface of the screw 401, preventing axial movement during subsequent use.

[0024] Next, adjust the installation position of screw 401 so that both ends of screw 401 are fully embedded in the corresponding insertion holes 500 of the support 400, ensuring the coaxiality of screw 401 and insertion holes 500. Finally, pass the fastening bolt 501 through the mounting hole 502 on the support 400 and screw it in until the end of the fastening bolt 501 is in tight contact with the surface of screw 401. The radial tightening force achieves radial limiting and circumferential fixation of screw 401 inside the support 400, thus completing the reliable assembly of the three components.

[0025] A screw 600 is rotatably connected to the side of the support 400 away from the cutting part 403. A threaded part 602 is threaded on the surface of the screw 600, and a knob 601 is snapped onto the end of the screw 600 away from the support 400. A horizontal plate 700 is fixedly sleeved on the surface of the threaded part 602, and the horizontal plate 700 is snapped onto the bracket 100.

[0026] Specifically, rotating knob 601 drives screw 600 to rotate synchronously. Through the threaded engagement between screw 600 and threaded part 602, the rotational motion is converted into axial movement of screw 600, which in turn drives support 400 to move synchronously.

[0027] The support 400 is constrained by the bracket 100 and can only move longitudinally in a preset direction. It cannot rotate circumferentially with the screw 600, which effectively avoids attitude deviation during the movement of the support 400 and lays a stable foundation for the coordinated work of subsequent related components.

[0028] A supporting cutting ring 800 is provided on one side of the cutting part 403, and a polished surface 801 is formed on the outer surface of the supporting cutting ring 800 near the end of the cutting part 403. A middle part 802 is integrally formed at the end of the supporting cutting ring 800 away from the cutting part 403, and both ends of the middle part 802 are formed with symmetrically arranged inclined surfaces 803. A guide ring 804 is integrally formed at the end of the middle part 802 away from the supporting cutting ring 800, and both ends of the guide ring 804 are designed with an outward arc shape. A symmetrically arranged support rod 900 is snapped onto the outer surface of the supporting cutting ring 800. A mounting plate 300 is snapped onto one end of the support rod 900 and the surface of the rotating ring 402, and the mounting plate 300 is fastened to the bracket 100 by bolts.

[0029] Specifically, the end of the support cutting ring 800 facing the cutting part 403 is machined with a sharp cutting surface. During operation, part of the insulation layer at the end of the wire needs to be peeled off first, and then the exposed copper core section is placed inside the support cutting ring 800. The unpeeled insulation layer is sleeved on the outside of the support cutting ring 800 to ensure accurate positioning of the cutting part.

[0030] As the wire steadily advances along the preset path, the insulation layer and copper core are automatically separated by the wire's own rigid support and the sharp cutting surface of the support cutter 800. At the same time, any remaining insulation layer on the wire surface is guided to the outside through the inclined surface 803 of the middle part 802 when it comes into contact with the middle part 802.

[0031] The guide ring 804 features an outer arc-shaped structure at both ends, ensuring smooth guidance of the wire and preventing deviation during wire transport. It also confines the stripped insulation layer within its outer arc, achieving complete separation of the insulation layer from the copper core. This design not only improves the cleanliness of the cutting and separation process but also facilitates the separate collection of the copper core and the individual processing of the insulation layer, ensuring the standardization and efficiency of the recycling process. The working principle of this invention is as follows: When stripping waste wires, the operator prioritizes selecting a collar 200 and a supporting cutting ring 800 that match the wire size, and installs them at an appropriate position on the bracket 100 using the mounting plate 300. Initially, the cutting piece 403 is close to the horizontal plate 700 and away from the guide roller 101. The wire is placed in the center of the surface of the guide roller 101, which uses an arc-shaped roller surface adapted to the outer diameter of the wire to guide and constrain its posture.

[0032] Next, the position of the cutting piece 403 is adjusted, and the screw 600 is driven to rotate synchronously by rotating the knob 601. Through the threaded engagement between the screw 600 and the threaded part 602, the rotational motion is converted into axial movement of the screw 600, which in turn drives the support 400 to move synchronously. Once the cutting piece 403 approaches the guide roller 101 and partially inserts into the wire insulation layer, the operator rotates the crank handle 103, causing the crank handle 103 to drive the wire roller to transmit the wire, thus transferring the wire. During this transfer, an opening is gradually cut into the wire insulation layer.

[0033] Once the cut wire is long enough to contact the support cutting ring 800, the operator manually separates the copper core from the insulation layer of that section, placing the exposed copper core section inside the support cutting ring 800, while the remaining insulation layer is placed on the outside of the support cutting ring 800, ensuring precise positioning of the cutting area. The actual wire stripping process can then begin.

[0034] As the guide roller 101 rotates continuously, the wire continues to advance. The end of the support cutting ring 800 facing the cutting element 403 is machined with a sharp cutting surface. As the wire steadily advances along the preset path, the sharp cutting surface of the support cutting ring 800 automatically completes the cutting and separation of the insulation layer and the copper core. Furthermore, the guide ring 804 adopts an outer arc structure design at both ends, which not only ensures the smooth guidance of the wire and prevents deviation during wire transportation, but also confines the stripped insulation layer inside its outer arc, achieving complete separation of the insulation layer and the copper core.

[0035] When it is necessary to replace the cutting part 403, the operator should first loosen the fastening bolt 501. After the screw 401 is released from the confinement in the socket 500, move the screw 401 so that one end is disengaged from the socket 500. At this time, the fastening nut 404 can be rotated so that the rotating ring 402 can move on the surface of the screw 401 until it is removed from the surface of the screw 401. Then the fastening nut 404 and the rotating ring 402 can be removed from the inside of the support 400.

[0036] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
