Technical Field

The present invention relates to the technical field of cable recycling, and in particular to a cable production recycling device and method.

Background technique

Cable is an electrical energy or signal transmission device, usually composed of one or more mutually insulated conductors and an outer insulating protective layer. During the upgrade and transformation of cable lines, a large number of cables need to be replaced, so a lot of scrap cables will be generated. The cable core has a very high recycling value, and the cable sheath is usually made of plastic. It is easy to pollute the environment if it is discarded at will. In order to comply with the concept of saving and environmental protection, the scrap cable sheath and metal core material need to be separated for recycling.

The patent document with announcement number CN117153497B discloses a waste cable recycling device, including a base, a stripping chamber is opened in the base, a guide tube is welded on the outer wall of the base, the guide tube extends to the stripping chamber, a mounting frame is welded on the outer wall of the guide tube, and a pair of knife holders are slidably inserted in the mounting frame. The invention can improve the cutting effect of the cutting knife by arranging a feed wheel and a cutting knife. By arranging a separation plate and welding barbs on the outer wall of the separation plate, when the two separation plates are opened, the outer skin can be grasped and pulled to both sides, simulating the effect of manual stripping and improving work efficiency.

However, the cable recovery device provided by the above patent document can only perform one separation on a single-core cable. For the recovery of multi-core cables, it is necessary to collect the internal cores one by one after the main line is separated from the core, and then perform a secondary separation on the internal cores. Therefore, the multi-core cable needs to undergo multiple separations of the outer sheath and the core during the recovery process. The process is cumbersome, time-consuming, and labor-intensive, and the recovery efficiency is low.

Detailed ways

Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

As shown in Figures 1 to 9, a cable production and recycling equipment of the present invention includes a frame 1, a first cutting mechanism, a correction component, a fixing component, a second cutting mechanism, a first driving component, a second driving component and a third driving component. The frame 1 includes a first supporting frame 11 for supporting the cable 5 and a second supporting frame 12 for supporting the wire core 52. The first cutting mechanism, the correction component, the fixing component and the second cutting mechanism are arranged sequentially along the conveying direction of the cable 5. In this embodiment, a three-core cable 5 is taken as an example. The three-core cable 5 is composed of three wire cores 52 and a filler 53 wrapped by a cable sheath 51, and each wire core 52 is composed of an inner core 522 and a wire core sheath 521 wrapped around the outside of the inner core 522.

When the cable production and recycling equipment of the present invention is in use, the waste cable 5 to be stripped is placed on the first support frame 11 and continuously transported forward. During the transportation of the cable 5, the cable sheath 51 can be cut by the first cutting mechanism to separate the cable sheath 51, the filler 53 and the wire core 52. Then, the separated multiple wire cores 52 can be corrected and positioned by the correction component, and the multiple wire cores 52 can be fixed by the fixing component. Then, the wire core sheath 521 can be cut by the second cutting mechanism to separate the wire core sheath 521 from the inner core 522. By subsequently collecting the cable sheath 51, the wire core sheath 521 and the inner core 522 separately, the waste cable 5 can be recycled.

The first cutting mechanism is used to cut the cable sheath 51 of the waste cable 5 to separate the cable sheath 51 from the wire core 52. The first cutting mechanism includes two first cutting wheel pieces 21 symmetrically arranged up and down, and a first guide piece 22 for guiding the cut cable sheath 51. The first driving component is arranged on the frame 1, and can drive the first cutting wheel piece 21 to rotate. The first guide piece 22 is provided with a lead-in opening 222 for the wire core 52 to pass through. One end of the first guide piece 22 has two first arc surfaces, and a sharp blade 223 facing the first cutting wheel piece 21 is formed between the two first arc surfaces.

Specifically, as shown in Figures 1 to 4, when the waste cable 5 moves to the first cutting mechanism, the first cutting wheel 21 is driven to rotate by the first driving assembly, and the waste cable 5 will pass through the middle of the two first cutting wheel blades 21. The two first cutting wheel blades 21 are symmetrically distributed up and down, and can cut the cable sheath 51 of the cable 5 into two halves longitudinally, thereby reducing the adhesion between the cable sheath 51 and the wire core 52, and facilitating the stripping of the cable sheath 51. As the cable 5 continues to move, the wire core 52 can continue to be transported forward through the lead-in opening 222 on the first guide member 22, and the two halves of the cable sheath 51 will be transported to both sides along the two arc surfaces after contacting the sharp blade 223 on the first guide member 22. As the cable 5 continues to be fed, the cable sheath 51 is gradually stripped off, completing the separation between the cable sheath 51 and the wire core 52.

The frame 1 also includes a fourth support frame 14, which is arranged between the first support frame 11 and the second support frame 12. The correction component is arranged on the fourth support frame 14. The correction component is used to correct multiple wire cores 52 that are separated from the cable sheath 51. The correction component includes a mounting cylinder 41, a rotating ring 42, a limiting cylinder 43 and a spring 44. The mounting cylinder 41 is fixed on the fourth support frame 14, the first guide member 22 is arranged at one end of the mounting cylinder 41 facing the first cutting wheel 21, the rotating ring 42 is arranged at one end of the mounting cylinder 41 away from the first guide member 22, the rotating ring 42 is rotatably connected to the mounting cylinder 41, a protrusion 431 is arranged on the outer wall of the limiting cylinder 43, a spiral groove 411 is opened on the inner wall of the mounting cylinder 41, and a limiting The cylinder 43 is slidably connected with the spiral groove 411 through a protrusion 431, and a plurality of limiting plates 432 for limiting the wire core 52 are arranged inside the limiting cylinder 43, and a gap for the wire core 52 to pass through is formed between two adjacent limiting plates 432, and the inner wall of the limiting cylinder 43 gradually tilts inward along the conveying direction of the wire core 52, so that when the wire core 52 passes through the limiting cylinder 43, the limiting cylinder 43 can move synchronously with the wire core 52 under the action of friction, and the spring 44 is arranged between the limiting cylinder 43 and the first guide member 22, and the first guide member 22 is provided with a guide groove 221 on the side facing the mounting cylinder 41, one end of the spring 44 is connected to the limiting cylinder 43, and the other end of the spring 44 is slidably arranged in the guide groove 221.

After the multiple cores 52 of the waste cable 5 are separated from the cable sheath 51, the core sheath 521 and the inner core 522 need to be separated. In order to facilitate the subsequent cutting of the core sheath 521, the multiple cores 52 need to be positioned and fixed. Therefore, the multiple cores 52 need to be unfolded to make them distributed in a plane. If the multiple cores 52 before unfolding are in a skewed state, the multiple cores 52 after unfolding may conflict with each other, affecting the unfolding effect of the cores 52. Therefore, before unfolding the cores 52, the cores 52 need to be corrected. In some embodiments, the cores 52 can be corrected manually. In this embodiment, the cores 52 can be corrected by a correction component. Specifically, as shown in Figures 1 to 7, the multiple cores 52 separated from the cable sheath 51 continue to be transported forward, and will contact the limiting cylinder 43, and drive the limiting cylinder 43 to move synchronously under the action of friction. During the movement of the limiting cylinder 43, under the guiding action of the spiral groove 411, the limiting cylinder 43 can rotate while moving. Until the wire core 52 can pass through the two adjacent limiting plates 432, the limiting cylinder 43 continues to rotate, driving the wire core 52 passing through the limiting plates 432 to rotate synchronously, and correcting the wire core 52. In the process of the limiting cylinder 43 moving from one end close to the first guide member 22 to the other end, under the guidance of the spiral groove 411, the limiting cylinder 43 rotates 120 degrees exactly. No matter how the multiple wire cores 52 are arranged initially, the wire core 52 will appear in the process of the limiting cylinder 43 rotating 120 degrees. 2 can just pass through between two adjacent limiting plates 432. At this time, the wire core 52 will rotate synchronously with the limiting cylinder 43 until the limiting cylinder 43 moves to the other end of the installation cylinder 41. At this time, the three wire cores 52 are arranged in a regular triangle at the lower left, lower right and upper middle, which is convenient for the subsequent unfolding of the three wire cores 52. After the recovery of the cable 5 is completed, the limiting cylinder 43 can move towards the direction close to the first guide member 22 under the action of the spring 44 to complete the reset of the limiting cylinder 43.

The fixing component is arranged on the second support frame 12, and is used to fix multiple wire cores 52 that are separated from the cable sheath 51. The fixing component includes a driving motor 15 arranged on the second support frame 12, and a fixing plate 16 connected to the output end of the driving motor 15. The fixing plate 16 is slidably connected to the second support frame 12, and an accommodating groove 100 for the wire core 52 to pass through can be formed between the lower end of the fixing plate 16 and the second support frame 12.

Specifically, as shown in Figures 1, 2, 3 and 7, after the corrected multiple wire cores 52 pass through the correction assembly, the multiple wire cores 52 are manually unfolded and placed on the second support frame 12 respectively, so that the multiple wire cores 52 are horizontally distributed, and then the fixing plate 16 is driven downward by the driving motor 15 to fix the multiple wire cores 52 in the corresponding accommodating grooves 100 respectively, so as to facilitate the subsequent cutting of the wire cores 52.

The second cutting mechanism is arranged on the second supporting frame 12, and is used for cutting the wire core skin 521 of the wire core 52, so that the wire core skin 521 is separated from the inner core 522. The second cutting mechanism includes a plurality of cutting components, and the plurality of cutting components are respectively used for cutting the plurality of wire cores 52. Each cutting component includes two cutting knives 31 symmetrically arranged on the left and right, two second cutting wheel pieces 32 symmetrically arranged on the upper and lower sides, and a second guide member 33 for guiding the cut wire core skin 521. The second guide member 33 is composed of two guide blocks 331. There is a gap between the two guide blocks 331 for the inner core 522 to pass through. The two guide blocks 331 are provided with a second arc surface on the opposite sides. Each guide block 331 has a guide tip 332 at one end facing the second cutting wheel piece 32. The second driving component is arranged on the frame 1, and can drive the cutting knife 31 to move up and down. The third driving component is arranged on the frame 1, and can drive the second cutting wheel piece 32 to rotate.

Specifically, as shown in Figures 1, 7 and 8, when the wire core 52 moves to the second cutting mechanism, the cutting knife 31 is driven by the second driving assembly to move downward to cut the wire core 52, exposing the inner core 522 on both sides of the wire core 52, so that the cut wire core 52 can pass between the two guide blocks 331, which is convenient for fixing the inner core 522 part in the subsequent cutting process, and then the cut wire core 52 part is cut again by the second cutting wheel 32, and the wire core skin 521 is cut into two halves along the longitudinal direction. The two halves of the wire core skin 521 will move to both sides along the second arc surface after contacting the corresponding guide tip 332 on the guide block 331. The second cutting mechanism is provided with a cutting knife 31 to cut the wire core 52, so that the inner core 522 on both sides of the wire core 52 is partially exposed, which can reduce the adhesion between the wire core skin 521 and the inner core 522, and facilitate the subsequent separation of the wire core skin 521 and the inner core 522.

In some embodiments, the frame 1 also includes a third support frame 13, the first drive assembly is arranged on the third support frame 13, the first drive assembly includes a first rotating shaft 23, and a first drive source 24 connected to one end of the first rotating shaft 23, the first cutting wheel 21 is sleeved on the outside of the first rotating shaft 23, and the first cutting mechanism also includes a first feed wheel 25 respectively arranged on both sides of the first cutting wheel 21, and the first feed wheel 25 is sleeved on the outside of the first rotating shaft 23.

Specifically, as shown in Figures 1 to 3, the first driving source 24 drives the first rotating shaft 23 to rotate, which can drive the first cutting wheel 21 and the first feed wheel 25 mounted on the outside of the first rotating shaft 23 to rotate. During the rotation of the first cutting wheel 21, the cable sheath 51 can be cut into two halves longitudinally. During the rotation of the first feed wheel 25, the cable 5 can be pushed forward. At the same time, a pointed tip is provided on the outer wall of the first feed wheel 25, which can effectively increase the friction between the cable 5 and the first feed wheel 25, thereby ensuring that the cable 5 can be pushed smoothly and avoiding sliding or slipping.

In some embodiments, the second driving assembly includes a second driving source 34 disposed on the fixing plate 16 , and a lifting plate 35 connected to an output end of the second driving source 34 , and the cutting blade 31 is connected to the lifting plate 35 .

Specifically, as shown in Figures 7 and 8, after the fixing plate 16 fixes the wire core 52, the lifting plate 35 is driven downward by the second driving source 34, and the cutting knife 31 set on the lifting plate 35 is driven to move downward. During the downward movement of the cutting knife 31, it can cut along the tangent direction of the inner core 522, so that the inner core 522 parts on both sides of the wire core 52 can be exposed. At this time, the remaining part of the wire core 52 can pass through between the two guide blocks 331.

In some embodiments, the third drive assembly includes a second rotating shaft 36, and a third drive source 37 connected to one end of the second rotating shaft 36. Multiple second cutting wheel blades 32 are all mounted on the outside of the second rotating shaft 36. The second cutting mechanism also includes second feed wheels 38 respectively arranged on both sides of the second cutting wheel blades 32. The second feed wheels 38 are mounted on the outside of the second rotating shaft 36. The second rotating shaft 36 located on the upper side is rotatably set on the lifting plate 35, and the second rotating shaft 36 located on the lower side is rotatably set on the second support frame 12.

Specifically, as shown in Figures 7 to 9, after the cutting knife 31 completes the cutting of the wire core skin 521, the second rotating shaft 36 is driven to rotate by the third driving source 37, which can drive the second cutting wheel 32 and the second feed wheel 38 mounted on the outside of the second rotating shaft 36 to rotate. During the rotation of the second cutting wheel 32, the wire core 52 can be longitudinally cut. During the rotation of the second feed wheel 38, the wire core 52 can be pushed forward. The second feed wheel 38 has the same structure as the first feed wheel 25, and both have the same effect.

In some embodiments, the third support frame 13 is provided with an adjustment structure for moving the first cutting wheel 21 up and down, the adjustment structure includes a slider 26 and a bolt 27, the first driving source 24 is installed on the slider 26, the bolt 27 is connected to the slider 26, and the third support frame 13 is provided with a mounting hole for the bolt 27 to pass through, so that the slider 26 and the fourth support frame 14 can be connected by the bolt 27.

Specifically, as shown in Figures 1 to 3, by adjusting the bolt 27, the first driving source 24 and the first rotating shaft 23 can be driven to move up and down. When the first rotating shaft 23 moves, the first cutting wheel 21 and the first feed wheel 25 mounted on the outside of the first rotating shaft 23 can be driven to move, thereby adjusting the cutting depth of the first cutting wheel 21 and the clamping distance of the first feed wheel 25, so that the first cutting mechanism can cut the cable sheath 51 of waste cables 5 of different sizes, thereby improving the applicability of the equipment.

After the cable sheath 51 is cut by the first cutting wheel 21, the wire core 52 continues to be transported forward, and the cable sheath 51 is transported to both sides under the action of the first guide 22. At the same time, the filler 53 inside the cable 5 will be transported to both sides along with the cable sheath 51, but there may be a part of the filler 53 with a large adhesion to the wire core 52, which will continue to be transported forward along with the wire core 52 and affect the cutting of the wire core sheath 521 in the subsequent process. Therefore, in some embodiments, the present invention also includes a blocking component, which can block the filler 53 inside the cable 5 53 is used to block, the blocking assembly includes a connecting rod 45, and a plurality of piercing members 451 arranged at one end of the connecting rod 45, a plurality of limiting plates 432 inside the limiting cylinder 43 are provided with through holes 433 for the connecting rod 45 to pass through, a protrusion 434 is connected to the inner wall of the through hole 433, a spiral groove 452 is provided on the outer wall of the connecting rod 45, the connecting rod 45 is slidably connected to the spiral groove 452 through the protrusion 434, one end of the connecting rod 45 away from the piercing member 451 is fixedly connected to the rotating ring 42, and a torsion spring is provided between the piercing member 451 and the connecting rod 45.

Specifically, as shown in Figures 3 to 6, when the wire core 52 separated from the cable sheath 51 moves toward the direction close to the limiting cylinder 43, the filler 53 attached to the wire core 52 will be driven to move synchronously. When the wire core 52 contacts the limiting cylinder 43, the limiting cylinder 43 will be driven to move, so that the limiting cylinder 43 slides along the spiral groove 411. When the limiting cylinder 43 gradually moves away from the first cutting wheel 21, the connecting rod 45 will gradually be exposed from the through hole 433 on the limiting cylinder 43. At this time, the multiple piercing members 451 on the connecting rod 45 will spread outwards under the action of the torsion spring, blocking the filler 53 attached to the wire core 52. By providing a spiral groove 2 452 on the outer wall of the connecting rod 45, the connecting rod 45 can rotate relative to the limiting cylinder 43 under the guidance of the spiral groove 2 452 during the sliding process of the limiting cylinder 43, and drive the piercing member 451 to rotate, pierce and fix the filler 53, so that the filler 53 can be peeled off from the core 52 during the subsequent forward conveying of the core 52. After completing the recovery of the cable 5, the limiting cylinder 43 is reset, so that the connecting rod 45 and the multiple piercing members 451 on the connecting rod 45 can be retracted into the through hole 433 again, so that the piercing member 451 can be separated from the filler 53.

As shown in FIGS. 1 to 9 , the present invention further provides a cable production and recycling method using the above-mentioned cable production and recycling equipment, which specifically comprises the following steps:

1) placing the waste cables 5 on the first support frame 11 and continuously conveying them forward;

2) When the cable 5 moves to the first cutting mechanism, the first driving assembly drives the two first cutting wheel pieces 21 to rotate, and the cable sheath 51 of the cable 5 is longitudinally cut into two halves, and the wire core 52 continues to be transported forward. The two halves of the cable sheath 51 are transported to both sides under the action of the first guide 22, so that the cable sheath 51 is separated from the wire core 52;

3) Correcting the plurality of wire cores 52 separated from the cable sheath 51 by means of a correction component, and fixing the plurality of wire cores 52 by means of a fixing component;
