Description

Technical Field

[0001] This utility model relates to the field of cable stripping machine technology, and in particular to a cable stripping device for cable recycling. Background Technology

[0002] After prolonged use, cables may experience reduced conductivity of the copper core, deterioration of the cable sheath's insulation, and short circuits. In such cases, it is necessary to replace the old cable with a new one. The copper core of the old cable can be recycled and reused. For this purpose, some manufacturers specialize in recycling waste cables and use cable stripping machines to remove the copper core.

[0003] Patent CN219643459U discloses a waste cable recycling stripping machine, including a housing and a stripping blade. A blade holder is installed on the top surface of the housing, and the stripping blade is installed inside the blade holder with its lower end extending into the housing. A mounting base is installed on the bottom surface of the housing, and a power roller is rotatably installed on the top surface of the mounting base. A motor is installed on one side of the housing, and the power roller is rotated by the motor. Limiting components with identical structures are installed on both upper side walls of the housing. The limiting components include a sliding groove, a sliding seat, a spring, a top block, and a push rod installed on the inner side wall of the housing. The spring and the top block are installed inside the sliding seat, and the top block can slide inside the sliding seat. One end of the top block extends out of the sliding seat, one end of the spring is connected to the top block, and the other end of the spring is connected to the inner wall of the sliding seat. The spring can effectively adapt to the diameter of the cable and correct its position. The push rod can adjust the height of the slide. The device uses a stripping knife to cut the cable sheath. However, for cable sheaths that are thick or hard, the cutting knife has difficulty cutting through them. Therefore, we propose a cable recycling stripping device. Utility Model Content

[0004] To address the issues mentioned in the background section and to achieve the aforementioned objectives, the present invention employs the following technical solution:

[0005] A cable stripping device for cable recycling includes a fixed platform and a placement plate. The fixed platform has a placement channel that runs through the front and back, and the placement plate extends forward out of the placement channel.

[0006] Two protruding blocks are symmetrically arranged on the upper and lower inner walls of the placement channel. A drilling machine connected to the first hydraulic rod is arranged on the side of the protruding block facing the placement plate. A moving ring coaxial with the central axis of the placement channel is arranged at the front of the fixed platform. At least two peeling heads are symmetrically arranged on the inner circumference of the moving ring.

[0007] Preferably, the placement plate is disposed within the placement channel and is capable of moving towards and away from each other. The placement plate changes its gap width so that the central axis of the cable placed on it is the same as that of the placement channel.

[0008] Preferably, a toothed rack is fixedly installed at the front of the fixed platform, and a matching motor is installed on the outer ring of the moving ring. The matching motor drives the gear that meshes with the toothed rack to rotate.

[0009] Preferably, the drilling machine has multiple drill bits arranged on the side facing the placement plate, and the distance between each drill bit is less than the diameter of the drill bit.

[0010] Preferably, the peeling head includes a second hydraulic rod, a bending handle, a separation pry head, and a telescopic clamp. The second hydraulic rod is fixedly installed in the inner ring of the moving ring, and the second hydraulic rod controls the movement of the bending handle installed at the end of the second hydraulic rod away from the moving ring through its own telescopic adjustment.

[0011] Preferably, the bending handle is bent toward the fixed platform so that the straight line in which the pointing direction of the separation pry head fixed to the end of the bending handle is parallel to the central axis of the placement channel.

[0012] Preferably, the telescopic clamp is located on the side of the separation pry head away from the fixed platform, and a telescopic rod connected to the telescopic clamp is installed inside the bending handle to control the telescopic clamp to face or move away from the cable.

[0013] Preferably, a guide rod is provided at the front of the fixed platform to pass through the moving ring, so as to prevent the moving ring from shifting when moving horizontally.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention uses a drilling machine to drill dense holes in the outer sheath of cables with thick or hard sheaths to create a tear-resistant area. Then, a peeling head is used to tear off the cable sheath with the tear-resistant area after drilling. Compared with the existing method of using a cutting blade, this invention can better handle cables with thick and hard sheaths. Attached Figure Description

[0019] 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. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Reference Figure 1 and 2 A cable stripping device for cable recycling includes a fixed platform 1 and a placement plate 2. The fixed platform 1 has a placement channel 101 that runs through the front and back. The placement plate 2 is disposed in the placement channel 101 and can move towards and away from each other. The cable to be stripped is placed horizontally between the gaps of the placement plates 2. A portion of the placement plate 2 extends forward out of the placement channel 101 to place the cable. The placement plate 2 changes the gap width so that the central axis of the cable placed on it is the same as that of the placement channel 101.

[0021] Two protruding blocks 3 are symmetrically arranged on the upper and lower inner walls of the placement channel 101. A drilling machine 5 connected to a first hydraulic rod 4 is arranged on the side of the protruding block 3 facing the placement plate 2. The first hydraulic rod 4 controls the drilling machine 5 to face or move away from the cable by its own extension and retraction. Multiple drill bits are arranged on the side of the drilling machine 5 facing the placement plate 2. The distance between each drill bit is less than the diameter of the drill bit. After the cable is placed in the gap of the placement plate 2, the first hydraulic rod 4 extends so that the drilling machine 5 drills a dense row of perforations at the top and bottom of the cable sheath, so that the cable sheath is easily torn apart from left to right and thus the cable core can be stripped.

[0022] The front of the fixed platform 1 is provided with a movable ring 6 coaxial with the central axis of the placement channel 101. At least two peeling heads 7 are symmetrically arranged on the inner circumference of the movable ring 6. Each peeling head 7 includes a second hydraulic rod 71, a bending handle 72, a separation pry head 73, and a telescopic clamp 74. The second hydraulic rod 71 is fixedly installed on the inner ring of the movable ring 6. The second hydraulic rod 71 controls the movement of the bending handle 72, which is installed on the end of the second hydraulic rod 71 away from the movable ring 6, through its own telescopic adjustment. The bending handle 72 bends toward the fixed platform 1 so that the straight line in which the direction of the separation pry head 73, which is fixed to the end of the bending handle 72, is parallel to the central axis of the placement channel 101.

[0023] A toothed rack 8 is fixedly installed at the front of the fixed platform 1, and a cooperating motor 9 is installed on the outer ring of the moving ring 6. The cooperating motor 9 drives the gear meshing with the toothed rack 8 to rotate, thereby driving the entire moving ring 6 to move toward or away from the fixed platform 1. A guide rod 10 is provided at the front of the fixed platform 1 that passes through the moving ring 6 to prevent the moving ring 6 from deviating when moving horizontally.

[0024] After the cable sheath is drilled, the moving ring 6 and the second hydraulic rod 71 are adjusted in position and length respectively so that the separating pry head 73 can be inserted into the gap between the inner core and the outer sheath of the cable cross section. Then the moving ring 6 moves towards the fixed platform 1, and the outer sheath pryed up by the separating pry head 73 is pulled laterally and breaks and separates at the junction of adjacent holes. As the moving ring 6 moves, the junctions of each hole will break in sequence, thereby successfully peeling the cable sheath off the cable core.

[0025] The telescopic clamp 74 is located on the side of the separating pry head 73 away from the fixed platform 1. The bending handle 72 is equipped with a telescopic rod 75 that connects to the telescopic clamp 74. This rod is used to control the telescopic clamp 74 to face or move away from the cable. After the cable sheath is peeled off by the bending handle 72 and the separating pry head 73, the telescopic rod 75 extends out of the bending handle 72 and pushes the telescopic clamp 74 toward the surface of the cable core and makes it stick tightly. The telescopic clamp 74, which clamps the cable core, will move away from the fixed platform 1 along with the moving ring 6, thereby pulling out the stripped cable core so that the subsequent unstripped cable can be laid on the placement plate 2 for further stripping.
