Description

Technical Field

[0001] This utility model relates to the technical field of wire recycling equipment, and in particular to waste recycling equipment for power cord processing. Background Technology

[0002] Power cords are a type of wire specifically designed for transmitting electrical energy. They typically use high-purity copper as the conductor and are insulated with PVC plastic. During the production or disposal of power cords, waste wires, scraps, and defective products are generated. These wastes can be recycled to extract copper and plastic, enabling resource reuse.

[0003] However, the metal particles separated by mechanical crushing often have fine insulation residue attached to their surface, which leads to a decrease in the purity of the recovered metal and affects the quality of subsequent smelting. A small amount of metal debris is still mixed in the insulation after sorting, resulting in resource waste, especially negatively impacting the recovery rate of high-value metals. To improve this problem, the industry has gradually adopted the physical stripping method, which involves longitudinally cutting the insulation with a blade and then peeling off the internal metal wires to avoid mixed contamination caused by crushing. However, due to the large size difference of power cords, peeling off the cut insulation often requires a relatively complex mechanical structure, which significantly increases equipment costs and maintenance difficulty.

[0004] Therefore, to address the problem that after power cords are mechanically crushed and sorted, metal and insulation remain together, reducing recycling purity and increasing resource waste, a waste recycling device for power cord processing can be designed to solve the above problems. Utility Model Content

[0005] In order to overcome the problems that existing mechanical crushing and sorting methods in the process of power cord recycling result in metal and insulation materials remaining together, reducing recycling purity and causing resource waste, while physical stripping methods require complex mechanical structures due to the size differences of power cords, which increases equipment costs and maintenance difficulty.

[0006] The technical solution of this utility model is as follows: a waste recycling device for power cord processing, including a lower support; and a diverter plate. An upper support is fixedly connected to the upper end of the lower support, and an upper slide is slidably connected to the upper support. A three-column fixed rotating cylinder is rotatably connected inside both the lower support and the upper slide. A cutting blade wheel is provided at one end of each of the three-column fixed rotating cylinders. A diverter plate is fixedly connected to the rear end of both the lower support and the upper slide. A herringbone-shaped stripping insert is fixedly connected to the diverter plate. A copper outlet is opened at the rear end of the diverter plate. An adjusting bolt is rotatably connected to the upper end of the upper slide. The adjusting bolt is threadedly engaged with the upper end face of the upper support. Two inclined rollers are slidably connected to the three-column fixed rotating cylinder.

[0007] Preferably, the adjusting bolts are turned to adjust the vertical distance between the lower support and the upper slide, the vertical distance between the three-column fixed rotating drum and the cutting blade wheel, and the vertical distance between the two diverter plates according to the thickness of the power cord. Then, the power cord is inserted between the upper and lower three-column fixed rotating drums and the cutting blade wheel. The upper cutting blade wheel is then rotated by a servo motor, so that the power cord is clamped and wound backward by the rotating cutting blade wheel and the driven inclined pad wheel, and the power cord is simultaneously cut by the blade fixed in the middle of the cutting blade wheel. The blade wheel cuts the upper and lower ends of the power cord in sequence. Then, as the power cord continues to move backward, two herringbone-shaped stripping inserts are inserted into the cuts at the upper and lower ends of the power cord to separate the outer sheath. The copper core passes through the copper outlet and enters the roller crusher behind it. At the same time, under the pull of the copper core moving backward and the obstruction and compression of the herringbone-shaped stripping inserts, the separated outer sheath extends vertically along the side wall of the herringbone-shaped stripping inserts and slides to the side into the collection bucket.

[0008] Preferably, the upper and lower sets of three-column fixed rotating drums and cutting blade wheels are distributed in opposite front and rear positions. The surfaces of the cutting blade wheels and the inclined pad wheels are provided with grooves to increase friction. A blade is fixed in the middle of the cutting blade wheels.

[0009] Preferably, the three-column fixed rotating drum is rotatably connected to a bidirectional threaded rod in the middle. The bidirectional threaded rod is threadedly engaged with the inclined surface washer wheel. A hexagonal column is fixedly connected to one side of the bidirectional threaded rod, and a spring is slidably connected to one side of the hexagonal column.

[0010] Preferably, a limiting tooth groove is provided on one side of the three-column fixed rotating cylinder, and a limiting gear is provided on one side of the spring that is slidably connected to the hexagonal column, with the limiting tooth groove meshing with the limiting gear.

[0011] Preferably, a first pinch anti-slip ring is fixedly connected to one side of the limiting gear, a second pinch anti-slip ring is fixedly connected to the other side of the three-column fixed rotating cylinder, and a servo motor is installed on the side end face of the upper slide, and the servo motor is connected to the cutting blade wheel via a coupling.

[0012] Preferably, a collection bin is provided on both sides of the diverter plate, a sliding plate is provided between the two collection bins, and a double roller crusher is provided at the rear end of the sliding plate.

[0013] Preferably, a pad is installed at the lower end of the lower support, the pull-up bucket is slidably connected to the pad, and the slide plate is fixedly connected to the pad.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting up a diverter plate, herringbone stripping inserts, copper outlet, and adjusting bolts, the upper and lower distances of the three-column fixed drum and the cutting blade wheel, as well as the upper and lower distances of the two diverter plates, can be adjusted by turning the adjusting bolts. Then, the rotating cutting blade wheel and the driven inclined pad wheel will wind the power cord backward and cut the upper and lower ends of the power cord sheath at the same time. The upper and lower herringbone stripping inserts will be inserted into the cut cracks at the upper and lower ends of the power cord to separate the sheath. The copper core passes through the copper outlet and enters the roller crusher at the rear. At the same time, the upper and lower ends of the power cord will extend vertically along the side wall of the herringbone stripping inserts and slide down to the side into the receiving bucket. Thus, the power cord sheath is automatically stripped through a simple mechanism and sorted and placed at the same time to reduce the cost of the equipment.

[0016] 2. By setting up a bidirectional threaded rod, hexagonal column, inclined roller, and limiting gear, the limiting gear can be pressed into the limiting tooth groove by a spring in the normal state, making the bidirectional threaded rod, the three-column fixed rotating drum, and the inclined roller a whole. This ensures that the three-column fixed rotating drum and the bidirectional threaded rod can only rotate synchronously. If the left hand pinches the second anti-slip ring to prevent the three-column fixed rotating drum from rotating, and the right hand pinches the first anti-slip ring to pull the limiting gear out of the limiting tooth groove, then the right hand can twist the limiting gear and the bidirectional threaded rod to rotate, so that the two inclined rollers move closer or further apart. By changing the size of the triangular gap between the two inclined rollers, the cutting depth of the blade on the power cord can be adjusted. This allows for flexible adjustment of the cutting depth of the blade on the power cord according to the thickness of the power cord's outer sheath, ensuring the effectiveness of the cutting and preventing the copper core from scattering when entering the roller crusher due to excessive cutting depth.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-5 This utility model provides an embodiment of a waste recycling device for power cord processing, including a lower support 1 and a diverter plate 6. An upper support 2 is fixedly connected to the upper end of the lower support 1, and an upper slide 3 is slidably connected to the upper support 2. A three-column fixed rotating cylinder 4 is rotatably connected inside both the lower support 1 and the upper slide 3. A cutting blade wheel 5 is provided at one end of each of the three-column fixed rotating cylinders 4. The diverter plate 6 is fixedly connected to the rear ends of both the lower support 1 and the upper slide 3. A herringbone-shaped peeling insert 7 is fixedly connected to the diverter plate 6, and an opening is provided at the rear end of the diverter plate 6. There is a copper outlet 8. The upper end of the upper slide 3 is rotatably connected to an adjusting bolt 9, which is threaded into the upper end face of the upper support 2. Two inclined rollers 13 are slidably connected to the three-column fixed rotating cylinder 4. By turning the adjusting bolt 9, the vertical distance between the lower support 1 and the upper slide 3, the vertical distance between the three-column fixed rotating cylinder 4 and the cutting blade wheel 5, and the vertical distance between the two diverter plates 6 can be adjusted according to the thickness of the power cord. Then, the power cord is inserted between the upper and lower three-column fixed rotating cylinders 4 and the cutting blade wheel 5, and then the servo... Motor 18 rotates the upper cutting blade wheel 5, which, along with the driven inclined pad wheel 13, clamps and winds the power cable backward. Simultaneously, the power cable is cut by the blade fixed in the middle of the cutting blade wheel 5. The two cutting blade wheels 5 cut the upper and lower ends of the power cable sequentially. As the power cable continues to move backward, two herringbone-shaped stripping tabs 7 insert into the cuts at the upper and lower ends of the power cable to separate the outer sheath. The copper core then passes through the copper outlet 8 and enters the rear... In the roller crusher 21, the separated outer skin is pulled backward by the copper core and blocked and squeezed by the herringbone peeling insert 7. Its upper and lower ends will extend vertically along the side wall of the herringbone peeling insert 7 and slide into the collecting bucket 19 along the side wall of the herringbone peeling insert 7. The upper and lower sets of three-column fixed rotating drums 4 and cutting blade wheels 5 are distributed in opposite front and rear positions. The surfaces of the cutting blade wheels 5 and the inclined pad wheel 13 are provided with grooves to increase friction. A blade is fixed in the middle of the cutting blade wheel 5.

[0025] Please see Figures 3-5In this embodiment, a bidirectional threaded rod 10 is rotatably connected to the middle of the three-column fixed rotating drum 4. The bidirectional threaded rod 10 is threadedly engaged with the inclined surface washer 13. A hexagonal column 11 is fixedly connected to one side of the bidirectional threaded rod 10, and a spring 12 is slidably connected to one side of the hexagonal column 11. Rotating the bidirectional threaded rod 10 causes the two inclined surface washer 13 to move closer or further apart. When the two inclined surface washer 13 move closer together, the triangular gap between the two inclined surface washer 13 becomes smaller, making the volume of the power cord that can be accommodated in the gap smaller, resulting in the upper and lower ends of the power cord being closer to the blade on the cutting blade wheel 5. The contact depth decreases, thus reducing the cutting depth of the blade. Conversely, the triangular slit can accommodate more volume of the power cord, increasing the contact depth between the upper and lower ends of the power cord and the blade on the cutting blade wheel 5, thereby increasing the cutting depth of the blade. A limiting tooth groove 14 is provided on one side of the three-column fixed rotating drum 4, and a limiting gear 15 is provided on one side of the spring 12, which is slidably connected to the hexagonal column 11. The limiting tooth groove 14 meshes with the limiting gear 15. In the normal state, the limiting gear 15 is pressed into the limiting tooth groove 14 by the spring 12, allowing the bidirectional threaded rod 10 to pass through the hexagonal column 11 and the limiting tooth groove. 14 and the limiting gear 15 are integrated with the three-column fixed rotating drum 4 and the inclined surface washer 13, ensuring that the three-column fixed rotating drum 4 and the bidirectional threaded rod 10 can only rotate synchronously. A first pinch anti-slip ring 16 is fixedly connected to one side of the limiting gear 15, and a second pinch anti-slip ring 17 is fixedly connected to the other side of the three-column fixed rotating drum 4. A servo motor 18 is installed on the side end face of the upper slide 3, and the servo motor 18 is driven and connected to the cutting blade wheel 5 through a coupling. While the left hand pinches the second pinch anti-slip ring 17 to prevent the three-column fixed rotating drum 4 from rotating, the right hand pinches the first pinch anti-slip ring 16 to limit the rotation. After the gear 15 is pulled out from the limiting tooth groove 14, the limiting gear 15 can be rotated by turning it with the right hand, so that the bidirectional threaded rod 10 can be rotated through the limiting gear 15 and the hexagonal column 11. Both sides of the diverter plate 6 are provided with a collection bucket 19, and a slide plate 20 is provided between the two collection buckets 19. A roller crusher 21 is provided at the rear end of the slide plate 20. The collection bucket 19 is used to collect plastic outer skin, and the roller crusher 21 is used to crush the copper core in the power cord. A pad 22 is installed at the lower end of the lower support 1. The collection bucket 19 is slidably connected to the pad 22, and the slide plate 20 is fixedly connected to the pad 22.

[0026] In use, the limiting gear 15 is normally pressed into the limiting tooth groove 14 by the spring 12, making the bidirectional threaded rod 10, through the hexagonal prism 11, the limiting tooth groove 14, and the limiting gear 15, a whole with the three-column fixed rotating drum 4 and the inclined roller 13. This ensures that the three-column fixed rotating drum 4 and the bidirectional threaded rod 10 can only rotate synchronously. While the left hand pinches the second finger anti-slip ring 17 to prevent the three-column fixed rotating drum 4 from rotating, the right hand pinches the first finger anti-slip ring 16 to pull the limiting gear 15 out of the limiting tooth groove 14. Then, the right hand can turn the limiting gear 15 to rotate, so that the bidirectional threaded rod 10 can rotate through the limiting gear 15 and the hexagonal prism 11. The rotation of the bidirectional threaded rod 10 can cause the two inclined rollers 13 to rotate synchronously. When the two inclined rollers 13 move closer or further apart, the triangular gap between them becomes smaller, allowing the power cord to fit into the gap. This results in a smaller contact depth between the upper and lower ends of the power cord and the blades on the cutting blade wheel 5, thus reducing the cutting depth. Conversely, when they move further apart, the triangular gap can accommodate a larger volume of the power cord, increasing the contact depth between the upper and lower ends of the power cord and the blades on the cutting blade wheel 5, thus increasing the cutting depth. This allows for flexible adjustment of the cutting depth of the power cord based on its outer sheath thickness, ensuring effective cutting and preventing the copper core from scattering upon entering the roller crusher 21 due to excessive cutting depth.

[0027] Subsequently, the adjusting bolt 9 is turned to adjust the vertical distance between the lower support 1 and the upper slide 3, the vertical distance between the three-column fixed rotating drum 4 and the cutting blade wheel 5, and the vertical distance between the two diverter plates 6 according to the thickness of the power cord. Then, the power cord is inserted between the upper and lower three-column fixed rotating drums 4 and the cutting blade wheel 5. The servo motor 18 then rotates the upper cutting blade wheel 5, so that the power cord is clamped and wound backward by the rotating cutting blade wheel 5 and the driven inclined pad wheel 13, and the power cord is simultaneously cut by the blade fixed in the middle of the cutting blade wheel 5. The two cutting blade wheels 5 will cut the upper and lower ends of the power cord one after the other. The power cord is cut, and as it continues to move backward, two herringbone stripping inserts 7 insert into the cut slits at the top and bottom of the power cord to separate the outer sheath. The copper core then passes through the copper outlet 8 and enters the roller crusher 21 behind it. At the same time, the separated outer sheath, under the pull of the copper core moving backward and the obstruction and compression of the herringbone stripping inserts 7, will extend vertically along the side wall of the herringbone stripping inserts 7 and slide down to the side into the collection bin 19. Thus, the outer sheath of the power cord is automatically stripped through a simple mechanism, and sorted and placed at the same time to reduce the cost of the equipment.

[0028] Through the above steps, by setting up the diverter plate 6, the herringbone stripping insert 7, the copper outlet 8, and the adjusting bolt 9, the upper and lower distances of the three-column fixed rotating drum 4 and the cutting blade wheel 5, as well as the upper and lower distances of the two diverter plates 6, can be adjusted by turning the adjusting bolt 9. Then, the rotating cutting blade wheel 5 and the driven inclined pad wheel 13 will wind the power cord backward and cut the upper and lower ends of the power cord sheath at the same time. The upper and lower herringbone stripping inserts 7 will be inserted into the cut cracks at the upper and lower ends of the power cord to separate the sheath. The copper core will pass through the copper outlet 8 and enter the roller crusher 21 at the rear. At the same time, the upper and lower ends of the power cord will extend vertically along the side wall of the herringbone stripping insert 7 and slide down to the side into the receiving bucket 19. Thus, the power cord sheath is automatically stripped through a simple mechanism, and sorted and placed at the same time to reduce the cost of the equipment.
