Description

Technical Field

[0001] This utility model relates to the field of cable stripping technology, specifically to an environmentally friendly metal cable stripping device. Background Technology

[0002] Metal cables are wires or cables made of metal conductors (such as copper and aluminum), widely used in power transmission, communication, and control signal transmission. Because they contain metals like copper and aluminum, they have high recycling value, making them profitable to recycle. Currently, after recycling, metal cables require the removal of the outer insulation to collect the internal metal core. Insulation removal mainly involves mechanical stripping and incineration. Incineration causes significant pollution, damages the metal core, and may result in incomplete removal, leading to the cables being discarded.

[0003] The State Intellectual Property Office website published a power cable stripping device with authorization number CN221150788U. This device uses a limiting plate to clamp and constrain the cable, thus solving the problem of having to manually strip the cable. However, in actual use, the limiting plate cannot clamp the cable too tightly, otherwise it will affect the cable's traction. If it is clamped too loosely, it cannot provide a reliable constraint effect on the cable. It requires constant adjustment during use, making it inconvenient to use. Utility Model Content

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] An environmentally friendly metal cable stripping device includes a machine base. A cable-passing sleeve is installed on the front of the machine base. Fixing plates are fixedly installed at both ends of the cable-passing sleeve and are fixed to the machine base. A cutting wheel is installed directly above the cable-passing sleeve. A cutting opening is preset on the top of the cable-passing sleeve corresponding to the position of the cutting wheel. The cutting wheel extends into the cable-passing sleeve through the cutting opening.

[0006] Furthermore, a conveyor wheel is installed on the top left side of the machine base. At least three tension rollers are installed on the front of the machine base to the right of the conveyor wheel. Two balance rollers are installed to the right of the tension rollers near the top of the machine base. A second motor is installed inside the machine base corresponding to the position of the conveyor wheel, and the output end of the second motor is fixedly connected to the corresponding conveyor wheel. The conveyor wheel pulls the cable into the stripping device, and the tension rollers are used to adjust the tension of the cable after input; currently common tension rollers are used.

[0007] Furthermore, two guide rollers are installed on the front of the machine base below the right side of the balance roller. A core-collecting roller for collecting the core is installed near the bottom right side of the machine base, and a sheath-collecting roller for collecting the sheath is installed on the right side of the machine base via a support shaft. Motor three and motor four are respectively installed at the positions corresponding to the core-collecting roller and the sheath-collecting roller on the support shaft. The output ends of motor three and motor four are fixedly connected to the corresponding core-collecting roller and sheath-collecting roller, respectively. The core and sheath are collected separately, and the two guide rollers can also guide the core in two directions to peel it out from under the sheath, thus facilitating separate collection.

[0008] Furthermore, the threading sleeve is located between two balance rollers, and a fixed base is fixedly installed on the front of the machine corresponding to the two balance rollers. A motor is installed near the top of the fixed base, and the cutting wheel is fixedly connected to the output end of the motor. One end of a fixed plate is fixedly installed to the corresponding fixed base. Using a motor-driven cutting wheel for cutting and stripping, compared to a fixed blade type, the cutting wheel experiences less resistance when encountering a metal wire core during stripping.

[0009] Furthermore, the inner wall of the cable conduit is pre-formed with multiple uniform strip grooves. The straight lines of the groove edges are used to prevent the cable from rolling.

[0010] Furthermore, multiple straightening sleeves are fixedly installed on the front of the machine base at the tension roller position. Each straightening sleeve contains at least four sets of strip rollers, with two strip rollers in each set. Each set of strip rollers is fixed to the straightening sleeve via a corresponding shaft bracket. The strip rollers abut against the outer sheath of the cable, and the four sets of strip rollers are staggered. The four sets are staggered at 45° to each other, with two rollers in each set, allowing the cable to be straightened by compression from eight directions.

[0011] Furthermore, a mounting base is fixedly installed on the front of the machine corresponding to the position of the straightening sleeve. A T-shaped rod facing the mounting base is fixedly installed on the rear side of each straightening sleeve. A support sleeve is fixedly installed on the mounting base corresponding to the position of the T-shaped rod. The T-shaped rod extends into the support sleeve and movably engages with the support. The T-shaped rod and the support sleeve cooperate to meet the position adjustment requirements of the straightening sleeve, thereby adapting to different positions of the cable.

[0012] Furthermore, the outer surface of the roller is designed with a concave arc shape, lower in the middle and higher around the edges. This concave design facilitates the straightening and compression of the cable, preventing small-area contact from exacerbating the slight bending of the cable.

[0013] Furthermore, a guide roller is installed on the front of the machine base between the guide roller and the wire core collecting roller. The wire core is supported on the surface of the guide roller. A telescopic rod is installed on the machine base at the position of the guide roller, and the telescopic rod is fixed to the machine base by a fixing frame. The guide roller is used to guide the winding position of the wire core on the wire core collecting roller, so that the wire core can be wound and collected neatly and stably on the wire core collecting roller.

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

[0015] 1. This utility model uses a cable sleeve to wrap and constrain the cable, which is fully wrapped and cannot swing, thus ensuring stability during cutting and stripping, and ensuring that the cutting wheel can accurately and reliably cut the outer sheath.

[0016] 2. In this utility model, a motor-driven cutting wheel is used to cut the cable sheath. When it accidentally comes into contact with the cable core, the running resistance between the cutting wheel and the core is smaller, and it is less likely to cause damage to the core. Combined with the strip groove in the cable sleeve, the possibility of contact with the core can be reduced.

[0017] 3. In this utility model, the cable is straightened, especially the curved cable with a small arc, so that it can pass through the cable sleeve, and at the same time, it can also ensure the precise cutting of the outer sheath by the cutting wheel.

[0018] 4. The arc-shaped concave surface of the strip roller in this utility model increases the contact surface with the cable, which on the one hand ensures the straightening effect of extrusion, and on the other hand, with multiple sets of strip rollers, it can achieve full coverage of all sides of the cable.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0028] This application provides an environmentally friendly metal cable stripping device, mainly solving the problem of cumbersome and inconvenient adjustment of the cable clamping force by the limiting plate in the prior art, and provides the following technical solution, which will be combined with... Figures 1-7 Please provide a detailed explanation:

[0029] An environmentally friendly metal cable stripping device includes a machine base 1. A conveyor wheel 2 is installed on the left side of the front of the machine base 1 near the top. At least three tension rollers 3 are installed on the front of the machine base 1 to the right of the conveyor wheel 2. Two balance rollers 4 are installed on the right side of the tension rollers 3 near the top of the machine base 1. Two guide rollers 5 are installed on the front of the machine base 1 below the right side of the balance rollers 4. The two guide rollers 5 are staggered vertically and horizontally. A wire core collecting roller 13 is installed on the bottom right side of the front of the machine base 1. A wire sheath collecting roller 14 is installed on the right side of the machine base 1 via a support shaft seat 17.

[0030] Inside the machine base 1, motors 2 15, 3 16, and 4 18 are respectively installed at the positions corresponding to the conveyor wheel 2, the core collecting roller 13, and the support shaft seat 17 at the position corresponding to the sheath collecting roller 14. The output ends of motors 2 15, 3 16, and 4 18 are respectively fixedly connected to the corresponding conveyor wheel 2, core collecting roller 13, and sheath collecting roller 14.

[0031] A fixed base 6 is fixedly installed between two balance rollers 4 on the front of the machine base 1. A motor 7 is installed near the top of the fixed base 6. A cutting wheel 8 is fixedly connected to the output end of the motor 7. A threading sleeve 9 is installed directly below the cutting wheel 8. Fixed plates 10 are fixedly installed at both ends of the threading sleeve 9. One end of the fixed plate 10 is fixedly installed to the fixed base 6 at the corresponding position. A cutting opening 11 is preset on the top of the threading sleeve 9 corresponding to the position of the cutting wheel 8. The cutting wheel 8 extends into the threading sleeve 9 through the cutting opening 11.

[0032] When using, first manually pull and install the cable 28. First, wrap the cable 28 around the conveyor wheel 2 once or twice. Then, pull the cable 28 around each tension roller 3 and pull it onto the balance roller 4. Pass it through the cable sleeve 9. Use the cutting wheel 8 to cut open the outer sheath of the cable 28. Guide the cut-open wire sheath 29 through the guide roller 5 at the corresponding position and pull it onto the wire sheath collection roller 14 for fixation. Guide the cut-open wire core 30 through the guide roller 5 at the corresponding position and pull it onto the wire core collection roller 13 for fixation. At this time, the manual pulling and installation is completed. Then, start the stripping process.

[0033] When motor 15 operates, the cable 28 is pulled by the friction of winding around the conveyor wheel 2. At the same time, the core collecting roller 13 and the sheath collecting roller 14 also pull the stripped core 30 and sheath 29 to rewind, so that the cable 28 is conveyed from left to right in the threading sleeve 9. The threading sleeve 9 constrains the entire cable 28, so that the cable 28 can maintain reliable contact with the cutting wheel 8, thereby ensuring the effective cutting and stripping by the cutting wheel 8. When motor 7 operates, it drives the cutting wheel 8 to rotate. The cutting wheel 8 cuts and slices the sheath 29 of the cable 28, and then guides it to the corresponding collecting roller through the two guide rollers 5 on the right side for winding, completing the stripping operation. For metal cables of different diameters, threading sleeves of the corresponding diameter specifications are preset for use.

[0034] In some embodiments, the inner wall of the conduit 9 is provided with a plurality of uniformly spaced grooves 12. When the cable 28 is inserted into the conduit 9, the grooves 12 are arranged such that the actual contact surface between the outer sheath of the cable 28 and the conduit 9 is not at the position of the groove 12. When the outer sheath of the cable 28 abuts against the straight edge of the groove 12, the cable 28 can be constrained, making it difficult for it to roll radially, ensuring its axial movement, and thus ensuring that the cutting wheel 8 cuts reliably and stably.

[0035] In some embodiments, multiple straightening sleeves 22 are fixedly installed on the front of the machine base 1 at the position of tension roller 3. Each straightening sleeve 22 has at least four sets of strip rollers 24 installed inside, and each set of strip rollers 24 has two rollers. Each set of strip rollers 24 is fixedly installed to the straightening sleeve 22 through a shaft bracket 23 at a corresponding position. The strip rollers 24 abut against the outer sheath of the cable 28. Depending on the diameter of the cable 28, the straightening sleeve 22, like the threading sleeve 9, is provided with various specifications of corresponding sizes. The four sets of strip rollers 24 are staggered. For example, the two rollers 24 in the first group are located at the twelve o'clock and six o'clock positions respectively; the two rollers 24 in the second group are located between ten o'clock and eleven o'clock and between four o'clock and five o'clock respectively, which are the positions of ten-thirty and four-thirty on the hour hand; the two rollers 24 in the third group are located at nine o'clock and three o'clock respectively; and the two rollers 24 in the fourth group are located between seven o'clock and eight o'clock and between one o'clock and two o'clock respectively, which are the positions of seven-thirty and one-thirty on the hour hand, so that the rollers 24 in adjacent groups are staggered at an angle of 45°.

[0036] When cable 28 passes through tension roller 3, it simultaneously passes through straightening sleeve 22. The strip roller 24 abuts against cable 28. As cable 28 is conveyed, the abutting force of strip roller 24 on the surface straightens cable 28, especially for small-radius bends. Large-radius bends after passing through tension roller 3 can be straightened by threading sleeve 9, so that cable 28 can maintain a high degree of straightness when passing through threading sleeve 9, thereby ensuring that cutting wheel 8 cuts the outer sheath but does not easily cut the internal metal wire.

[0037] In some embodiments, a mounting base 25 is fixedly installed on the front of the machine base 1 corresponding to the position of the straightening sleeve 22. A T-shaped rod 26 facing the mounting base 25 is fixedly installed on the rear side of each straightening sleeve 22. A support sleeve 27 is fixedly installed on the mounting base 25 corresponding to the position of the T-shaped rod 26. The T-shaped rod 26 extends into the support sleeve 27 and is movably sleeved for support.

[0038] The T-shaped rod 26, together with the support sleeve 27, provides fixation for each straightening sleeve 22. At the same time, the movable connection between the T-shaped rod 26 and the support sleeve 27 allows the front and rear positions of the straightening sleeve 22 to be adjusted. Thus, the straightening sleeve 22 can be pulled back and forth to make adaptive adjustments according to the position of the cable 28, avoiding pulling the cable 28 outward.

[0039] In some embodiments, the outer surface of the strip roller 24 is provided with an arc-shaped concave surface that is lower in the middle and higher around the edges. Compared with a cylindrical surface, the concave surface has a larger contact area with the surface of the cable 28, thus achieving a better extrusion and straightening effect.

[0040] In some embodiments, a guide wheel 19 is installed on the front of the machine base 1 at the position between the guide roller 5 and the wire core collecting roller 13. The wire core 30 is supported on the surface of the guide wheel 19. A telescopic rod 20 is installed on the machine base 1 at the position of the guide wheel 19. The telescopic rod 20 is fixed to the machine base 1 by a fixing frame 21. The telescopic rod 20 is any one of a hydraulic, electric or pneumatic telescopic rod.

[0041] When the wire core 30 is wound up, the telescopic rod 20 extends and retracts in an orderly and uniform manner, driving the guide wheel 19 to move back and forth within the collection range of the wire core collecting roller 13, so that the wire core 30 can be orderly wound and collected from the inside to the outside.

[0042] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
