Description

Technical Field

[0001] The present application relates to the technical field of cable recycling, and in particular to a cable stripping device. Background Art

[0002] In the field of waste cable recycling, cable stripping is of great significance. Waste cables contain a large amount of reusable metal resources, such as copper and aluminum. These metals have high economic value. However, the insulation material on the outer layer of the cable will hinder the effective recycling of the internal metal. Through stripping, the metal conductor can be separated from the insulating sheath, so that the metal can be recycled and refined and put back into industrial production, realizing the recycling of resources and reducing dependence on primary metal resources. At the same time, it reduces the potential pollution risk of waste cables to the environment, which is in line with the environmental protection concept of sustainable development.

[0003] In the related art, a stripping machine is usually used to strip the insulation layer of the cable. When the cable passes through the equipment, the tool contacts the cable sheath and cuts and strips it. Its working principle is to rely on a motor to drive the cable or tool to move, and use the sharp edge of the tool to cut into the sheath to achieve stripping. However, this stripping machine has poor adaptability and can usually only strip cables within a specific diameter range. When the diameter of the scrap cable exceeds its design range, it either cannot be stripped normally or will cause excessive damage to the cable, resulting in a high equipment idle rate during the cable recycling process, increasing the recycling cost. In addition, the cable is prone to displacement, shaking or twisting during stripping, which not only affects the accuracy and quality of stripping, resulting in incomplete or damaged metal conductor recovery, but may also cause equipment failure or safety accidents, threatening the personal safety of operators.

DETAILED DESCRIPTION

[0021] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0022] The cable stripping device according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0023] The cable stripping device provided in the embodiment of the present application can be used in the recycling process of waste cables for stripping waste cables. It can flexibly cope with cables of various diameters and different insulation thicknesses, thereby effectively reducing the equipment idle rate caused by differences in cable specifications, thereby effectively reducing costs in the cable recycling process. In addition, it can also effectively improve the stability of the cable stripping process and reduce the probability of safety hazards caused by unstable factors such as cable shaking and deviation during the stripping process.

[0024] like Figure 1-Figure 4 As shown, the cable stripping device of the embodiment of the present application may include an operating platform 1, a support frame 2, a first opposite driving mechanism 3, a second opposite driving mechanism 4, two cutting mechanisms 5, two conveying mechanisms 6 and two positioning and guiding mechanisms 7.

[0025] Among them, the support frame 2 is fixedly set on the operating platform 1, the first opposite driving mechanism 3 and the second opposite driving mechanism 4 are respectively arranged on the operating platform 1, and the first opposite mechanism and the second opposite driving mechanism 4 are respectively located on both sides of the support frame 2, the two cutting mechanisms 5 are respectively arranged on the first opposite driving mechanism 3, and the two cutting mechanisms 5 are respectively located above and below the support frame 2, the two conveying mechanisms 6 are respectively arranged on the second opposite driving mechanism 4, and the two conveying mechanisms 6 are respectively located between the two cutting mechanisms 5, and the two positioning guide mechanisms 7 are respectively arranged on the support frame 2, and the two positioning guide mechanisms 7 are respectively located on the front and back of the two conveying mechanisms 6.

[0026] Specifically, when the waste cable needs to be stripped, the relevant personnel first drive the two cutting mechanisms 5 to move towards each other according to the diameter information of the cable through the first opposite driving mechanism 3, and adjust them to a suitable spacing to adapt to the outer diameter of the cable and the thickness of the insulation layer. During the cutting process, the first opposite driving mechanism 3 can also provide a stable driving force to ensure that the tool of the cutting mechanism 5 cuts into the cable insulation layer evenly, and can be precisely controlled according to the preset cutting depth parameters to prevent excessive cutting from damaging the internal metal conductor.

[0027] Then, the relevant personnel drive the two conveying mechanisms 6 to move towards each other through the second opposite driving mechanism 4, so that they are in close contact with the cable and provide appropriate clamping force. The surface of the conveying mechanism 6 uses anti-slip materials, such as rubber or textured metal, to increase the friction between the cable and ensure that the cable can be stably conveyed during the stripping process. The operating speed of the conveying mechanism 6 can be adjusted according to factors such as the material and diameter of the cable. For example, for thicker and harder cables, the conveying speed is reduced to ensure the quality of cutting and stripping. For thinner cables, the conveying speed can be appropriately increased to improve work efficiency. During the entire stripping process, the conveying mechanism 6 continuously and stably conveys the cable forward, so that the cable passes through the cutting mechanism 5 and the positioning guide mechanism 7 in turn to complete the stripping operation.

[0028] The positioning guide mechanism 7 can automatically adjust the guide spacing according to the diameter of the cable, so that the cable can be accurately located between the two cutting mechanisms 5, and maintain linear motion during the stripping process to avoid shaking, deviation, etc. of the cable.

[0029] In one embodiment of the present application, Figure 1-Figure 4 As shown, the first opposite driving mechanism 3 may include a first bidirectional screw 301 , a first limiting rod 302 , two movable frames 303 and a first turning handle 304 .

[0030] Among them, the first bidirectional screw 301 is rotatably arranged on the operating platform 1, the two movable frames 303 are respectively threadedly connected to the first bidirectional screw 301, and the two movable frames 303 are respectively threadedly connected to the threaded sections in opposite directions on the first bidirectional screw 301, the first limit rod 302 is fixedly arranged on the operating platform 1, and the first limit rod 302 is respectively slidably connected to the two movable frames 303, and the first turning handle 304 is fixedly arranged on one end of the first bidirectional screw 301.

[0031] In one embodiment of the present application, two cutting mechanisms 5 are respectively disposed on two movable frames 303 , and the cutting mechanisms 5 may include a first motor 501 , a driving rod 502 and a cutting tool 503 .

[0032] The driving rod 502 is rotatably arranged on the movable frame 303 , the first motor 501 is arranged on the movable frame 303 , and the output shaft of the first motor 501 is coaxially connected to one end of the driving rod 502 through a coupling, and the cutting tool 503 is sleeved on the driving rod 502 .

[0033] In one embodiment of the present application, the second opposite driving mechanism 4 may include a second bidirectional screw 401 , a second limiting rod 402 , two lifting frames 403 and a second turning handle 404 .

[0034] Among them, the second bidirectional screw 401 is rotatably arranged on the operating platform 1, the second bidirectional screw 401 is located on the side of the support frame 2 away from the first bidirectional screw 301, the two lifting frames 403 are respectively threadedly connected to the second bidirectional screw 401, and the two lifting frames 403 are respectively threadedly connected to the threaded sections in opposite directions on the second bidirectional screw 401, the second limiting rod 402 is fixedly arranged on the operating platform 1, and the second limiting rod 402 is respectively slidably connected to the two lifting frames 403, and the second turning handle 404 is fixedly arranged on one end of the second bidirectional screw 401.

[0035] In one embodiment of the present application, two conveying mechanisms 6 are respectively disposed on two lifting frames 403 , and the conveying mechanism 6 may include a conveying roller 1 601 , a conveying roller 2 602 and two second motors 603 .

[0036] Among them, the ends of the conveying roller 1 601 and the conveying roller 2 602 that are away from each other are respectively rotatably connected to the lifting frame 403, and the conveying roller 1 601 and the conveying roller 2 602 are respectively located on both sides of the cutting tool 503, and the two second motors 603 are respectively arranged on both sides of the support frame 2, and the output shafts of the two second motors 603 are coaxially connected to the ends of the conveying roller 1 601 and the conveying roller 2 602 that are away from each other through couplings.

[0037] In one embodiment of the present application, the positioning and guiding mechanism 7 may include two electric push rods 701 , two fixing frames 702 and a guide roller 703 .

[0038] Among them, the fixed ends of the two electric push rods 701 are respectively fixedly set on the support frame 2, and the movable ends of the two electric push rods 701 are set close to each other, the two fixed frames 702 are respectively fixedly set on the movable ends of the two electric push rods 701, and the two guide rollers 703 are respectively rotatably connected to the two fixed frames 702. The two guide rollers 703 are respectively located on the side where the two fixed frames 702 are close to each other, and the two guide rollers 703 are respectively perpendicular to the conveying roller 1 601 and the conveying roller 2 602.

[0039] As a possible situation, the first handle 304 and the second handle 404 described in the above embodiment can be replaced by existing servo motors on the market, and the servo motors are connected to the remote control system and the power supply to further improve the control accuracy of the cutting tool 503 and the conveying mechanism 6.

[0040] As another possible situation, one of the conveying mechanisms 6 described in the above embodiment may not be provided with the second motor 603 to further reduce the production cost of the present application.

[0041] Specifically, the relevant personnel operate the first handle 304 to adjust the first opposing driving mechanism 3 according to the approximate diameter range of the waste cables to be processed. The first handle 304 is turned to drive the first bidirectional screw 301 to rotate. Since the two movable frames 303 are respectively connected to the threaded sections in opposite directions on the first bidirectional screw 301 and are limited by the sliding of the first limit rod 302, the two movable frames 303 will move toward or away from each other. The two movable frames 303 are initially adjusted to a suitable spacing, which is slightly larger than the expected maximum diameter of the cable, to facilitate subsequent precise adjustment.

[0042] Similarly, for the second opposite driving mechanism 4, the second handle 404 is turned to rotate the second bidirectional screw 401, thereby driving the two lifting frames 403 to move toward or away from each other under the restriction of the second limit rod 402, and preliminarily adjusting the conveying mechanism 6 on the two lifting frames 403 to a suitable height position so that the conveying roller 1 601 and the conveying roller 2 602 can be at approximately the same horizontal height as the cable and have enough space to accommodate the cable.

[0043] Subsequently, the relevant personnel placed the waste cable on the operating table 1, placed it close to the positioning guide mechanism 7, and started the electric push rod 701. According to the actual diameter of the cable, the movable end of the electric push rod 701 drove the fixed frame 702 to move, and then adjusted the distance between the two guide rollers 703, so that the cable can be accurately located between the two guide rollers 703. The two guide rollers 703 are perpendicular to the conveying roller 1 601 and the conveying roller 2 602, which can effectively limit the horizontal and vertical position of the cable, ensuring that the cable is in the correct position and remains in a straight state before entering the conveying mechanism 6, avoiding the cable from being offset or twisted.

[0044] Then, the relevant personnel start the second motor 603. The output shaft of the second motor 603 drives the conveying roller 1 601 and the conveying roller 2 602 to rotate through the coupling. The two conveying rollers 1 601 and 602 cooperate with each other and convey the cable by relying on the friction force with the cable surface. The conveying rollers 1 601 and 602 are located on both sides of the cutting tool 503, which can stably clamp and convey the cable to ensure the continuity of the stripping process. When the cable is transported to the cutting mechanism 5, according to the diameter of the cable and the thickness of the insulation layer, The first opposing driving mechanism 3 is precisely adjusted again, and the distance between the two movable frames 303 is finely adjusted by rotating the first turning handle 304, so that the cutting tool 503 is tightly fitted to the outer periphery of the cable and can accurately cut into the insulation layer, and the first motor 501 is started. The output shaft of the first motor 501 drives the driving rod 502 to rotate through the coupling, thereby causing the cutting tool 503 sleeved on the driving rod 502 to rotate at a high speed. Driven by the first opposing driving mechanism 3, the cutting tool 503 cuts and strips the insulation layer of the cable from the upper and lower directions of the cable.

[0045] As the cable is continuously conveyed, the cutting tool 503 completely strips off the insulation layer of the cable, and the internal metal conductor smoothly passes through the cutting area under the conveyance of the conveying mechanism 6, completing the entire stripping process. During the entire process, various mechanisms work together, the positioning and guiding mechanism 7 ensures a stable conveying path for the cable, the conveying mechanism 6 provides stable conveying power, the cutting mechanism 5 accurately performs the stripping operation, and the first opposite driving mechanism 3 and the second opposite driving mechanism 4 flexibly adjust the positions of each component to adapt to cables of different specifications, thereby efficiently and safely realizing the stripping processing of waste cables.

[0046] In summary, the cable stripping device of the embodiment of the present application can flexibly cope with cables of various diameters and different insulation layer thicknesses, thereby effectively reducing the equipment idle rate caused by differences in cable specifications, thereby effectively reducing costs in the cable recycling process. In addition, it can also effectively improve the stability of the cable stripping process and reduce the probability of safety hazards caused by unstable factors such as cable shaking and deviation during the stripping process.
