Description

Technical Field

[0001] This utility model relates to the field of cable processing technology, specifically a cable stripping device. Background Technology

[0002] Cables are a general term for items such as optical cables and electrical cables. In the power industry, cable stripping devices are widely used for stripping power cables. Power cables are an indispensable part of the power system, used to transmit and distribute electrical energy. Cable stripping devices can quickly and accurately remove the outer sheath of cables, providing convenience for the installation, maintenance and repair of power equipment.

[0003] A Chinese patent with publication number CN112310785B discloses a cable stripping device, including a base, a positioning mechanism, a stripping mechanism, and a stripping removal mechanism on the base. The positioning mechanism includes a fixing ring with a connecting rod on it, and a positioning wheel connected to the connecting rod. The stripping mechanism includes a stripping bracket, a stripping blade holder, a threaded rod, a nut, a lead screw, and a guide wheel. The threaded rod is threadedly connected to the nut and is connected to the stripping blade holder. The stripping removal mechanism includes a stripping bracket, a stripping roller, a second nut, a second threaded rod, and a stripping blade holder. The second nut is fixed to the stripping roller, and the second threaded rod is threadedly connected to the nut and is connected to the stripping blade holder. This invention reduces the workload of cable stripping, decreases labor intensity, improves work efficiency, and ensures safety.

[0004] When stripping cables, the blades wear down and become dull as the stripping operation continues. Existing cable stripping devices lack corresponding sharpening mechanisms, which leads to continuous wear and dulling of the blades, reducing their sharpness. Dull blades can easily cause incomplete stripping or damage to the internal conductors of the cable, thus affecting the stripping quality. Therefore, a cable stripping device is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background technology, this utility model proposes a cable stripping device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The cable stripping device of this utility model includes a base, on which a first support seat and a second support seat are fixedly connected. A housing is installed on the first support seat and the second support seat. Four first pneumatic cylinders are installed at the port of the housing. Each first pneumatic cylinder is equipped with a first pneumatic rod at its working end. The other end of each first pneumatic rod is equipped with a mounting seat. A cutter is installed in each mounting seat through a rotating shaft. A first motor is installed on one outer wall of each mounting seat. The output end of each first motor is connected to one end of the corresponding rotating shaft. When stripping the cable, the cable firstly enters the housing through the wire hole. Then, the cable is conveyed into the stripping mechanism by the limiting conveying mechanism. The first pneumatic cylinder is activated, causing the first pneumatic rod to move the cutter into the cable insulation sheath. When the cable passes between the four cutters, the high-speed rotation of the cutters completes the cutting of the cable insulation sheath. After cutting, the cut sheath is easily removed from the cable, thus completing the cable stripping process.

[0007] Preferably, each mounting base is equipped with a sharpening mechanism, which includes a second motor. The second motor is mounted on one side wall of each mounting base. The output end of the second motor is connected to a bidirectional lead screw, and the other end of the bidirectional lead screw is rotatably mounted on the other side wall of the mounting base. Two movable blocks are sleeved on the bidirectional lead screw, and a grinding stone is fixed to the bottom end of each movable block. The two grinding stones are located on opposite sides of the blade. When stripping the cable, the blade will continuously wear and become dull as the stripping operation continues. To prevent the blade from becoming dull, a sharpening mechanism is provided, which starts the second motor to sharpen the bidirectional lead screw. The rotation, in conjunction with the limiting rod and the limiting block, causes the two movable blocks to move the two grinding stones steadily closer to each other until the two grinding stones are in contact with the surface of the cutter. As the cutter 7 rotates at a uniform speed, the grinding stones help to grind the cutter evenly and effectively, thereby restoring its sharpness. Through the continuous grinding of the sharpening mechanism, the blade can always maintain a sharp state. The sharp blade can more accurately strip the cable sheath, reducing the possibility of sheath residue or damage to the internal conductor, thereby improving the stripping quality. At the same time, the sharpening mechanism can ensure that the blade maintains a consistent sharpness throughout the stripping process, thereby ensuring the consistency and reliability of the stripping operation.

[0008] Preferably, each mounting base has two limiting rods fixedly connected inside, and the two limiting rods are located on both sides of the bidirectional lead screw. Each movable block has a limiting block fixedly connected to both side walls, and the limiting rods pass through the limiting blocks. When using the device, the movement trajectory of the movable block can be limited by the cooperation of the limiting rods and the limiting blocks, so that the movable block can move stably.

[0009] Preferably, two second pneumatic cylinders are installed at the top and bottom of the circumferential surface of the housing. Each second pneumatic cylinder is equipped with a second pneumatic rod at its working end. The ends of the two second pneumatic rods at the same end are fixedly connected to mounting plates. Multiple fixed seats are connected to the two mounting plates. Each fixed seat is equipped with a pressing conveyor wheel through a rotating shaft. A third motor is installed on the side wall of the fixed seat at the first and last ends. The output end of the third motor is connected to one end of the rotating shaft. When the cable is being conveyed in a limited position, the second pneumatic cylinder is activated, causing the two mounting plates to move closer to each other, which in turn causes the two pressing conveyor wheels to move closer together until the two pressing conveyor wheels move to contact the surface of the cable. Then, the second pneumatic cylinder stops working, and the third motor is activated to make the pressing conveyor wheels rotate, thereby enabling the cable to be conveyed in a limited position. This structural design not only enables the automatic conveying of the cable but also ensures that the cable does not deviate during the conveying process.

[0010] Preferably, the first support base has a groove, and the first pneumatic cylinder located at the lowest end is disposed in the groove. One end of the housing has a wire hole. When using the device, the groove provides a space for the first pneumatic cylinder to be accommodated, allowing it to be stably installed on the first support base. The wire hole facilitates the entry of the cable into the housing.

[0011] The advantages of this utility model are:

[0012] 1. In this invention, when stripping cables, the blades will continuously wear and become dull as the stripping operation continues. To prevent the blades from becoming dull, a sharpening mechanism is set up. The second motor is started, causing the bidirectional lead screw to rotate. With the cooperation of the limiting rod and the limiting block, the two movable blocks drive the two grinding stones to move steadily closer to each other until the two grinding stones are in contact with the blade surface. As the blade 7 rotates at a uniform speed, the grinding stones help to evenly and effectively grind the blade, thereby restoring its sharpness. Through the continuous sharpening of the sharpening mechanism, the blade can always remain sharp. The sharp blade can more accurately strip the cable sheath, reducing the possibility of outer sheath residue or damage to the internal conductor, thereby improving the stripping quality. At the same time, the sharpening mechanism can ensure that the blade maintains a consistent sharpness throughout the stripping process, thereby ensuring the consistency and reliability of the stripping operation.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1 and Figure 4-6As shown, a cable stripping device includes a base 1, on which a first support 2 and a second support 3 are fixedly connected. A housing 4 is mounted on the first support 2 and the second support 3. Four first pneumatic cylinders 5 are installed at the ports of the housing 4. Each first pneumatic cylinder 5 has a first pneumatic rod mounted on its actuating end, and a mounting seat 6 is mounted on the other end of each first pneumatic rod. A cutter 7 is mounted in each mounting seat 6 via a rotating shaft. A first motor 8 is mounted on one outer wall of each mounting seat 6, and the output end of each first motor 8 is connected to a phase... One end of the corresponding rotating shaft is connected; when stripping the cable, the cable first enters the housing 4 through the wire hole 21, and then is transported to the stripping mechanism by the limiting conveying mechanism. The first pneumatic cylinder 5 is activated, and the first pneumatic rod drives the cutter 7 to move into the cable insulation sheath. When the cable passes between the four cutters 7, the high-speed rotation of the cutter 7 completes the cutting of the cable insulation sheath. After the cutting is completed, the cut sheath can be easily removed from the cable, thus completing the stripping process of the cable.

[0023] Each mounting base 6 is equipped with a sharpening mechanism, which includes a second motor 10. The second motor 10 is mounted on one side wall of each mounting base 6. The output end of the second motor 10 is connected to a bidirectional lead screw 11, and the other end of the bidirectional lead screw 11 is rotatably mounted on the other side wall of the mounting base 6. Two movable blocks 12 are sleeved on the bidirectional lead screw 11, and a grinding stone 13 is fixedly connected to the bottom end of each movable block 12. The two grinding stones 13 are located on both sides of the cutting tool 7. Two limiting rods 14 are fixedly connected within each mounting base 6, and the two limiting rods 14 are located on both sides of the bidirectional lead screw 11. Limiting blocks 15 are fixedly connected to both side walls of each movable block 12, and the limiting rods 14 pass through the limiting blocks 15. During cable stripping, as the stripping operation continues, the blade will continuously wear down and become dull. To prevent the cutting tool 7 from becoming dull, a sharpening mechanism is set up. The second motor 10 is started, causing the bidirectional lead screw 11 to rotate. With the cooperation of the limit rod 14 and the limit block 15, the two movable blocks 12 drive the two grinding stones 13 to move steadily closer to each other until the two grinding stones 13 move to contact the surface of the cutting tool 7. As the cutting tool 7 rotates at a uniform speed, the grinding stones 13 help to grind the cutting tool 7 evenly and effectively, thereby restoring its sharpness. Through the continuous sharpening of the sharpening mechanism, the blade can always maintain a sharp state. The sharp blade can more accurately strip the cable sheath, reducing the possibility of outer sheath residue or damage to the internal conductor, thereby improving the stripping quality. At the same time, the sharpening mechanism can ensure that the blade maintains a consistent sharpness during the stripping process, thereby ensuring the consistency and reliability of the stripping operation.

[0024] Please see Figure 3As shown, two second pneumatic cylinders 16 are installed at the top and bottom of the circumferential surface of the housing 4. Each second pneumatic cylinder 16 has a second pneumatic rod mounted on its actuating end. Mounting plates 17 are fixedly connected to the ends of the two second pneumatic rods at the same end. Multiple fixed seats 18 are connected to each of the two mounting plates 17. Each fixed seat 18 has a pressing conveyor wheel 19 installed inside it via a rotating shaft. A third motor 20 is installed on the side wall of the fixed seat 18 at the first and last ends. The output end of the third motor 20 is connected to one end of the rotating shaft. Before stripping the cable, the cable needs to be stably conveyed to… Inside the stripping mechanism, a limiting conveying mechanism is set up. When the cable is conveyed in a limiting manner, the second pneumatic cylinder 16 is activated, which causes the second pneumatic rod to drive the two mounting plates 17 to move closer to each other. This causes the two pressing conveying wheels 19 to move closer as well, until the two pressing conveying wheels 19 move to contact the surface of the cable. Then, the second pneumatic cylinder 16 stops working, and the third motor 20 is activated to make the pressing conveying wheels 19 rotate, thereby enabling the cable to be conveyed in a limiting manner. This structural design can not only complete the automatic conveying of the cable, but also ensure that the cable does not deviate during the conveying process.

[0025] Please see Figure 2 As shown, a groove 9 is provided on the first support base 2, and the first pneumatic cylinder 5 located at the lowest end is set in the groove 9. A wire hole 21 is provided at one end of the housing 4. When using the device, by setting the groove 9, a receiving space can be provided for the first pneumatic cylinder 5, so that it can be stably installed on the first support base 2. By setting the wire hole 21, it is convenient for the cable to enter the housing 4.

[0026] Working Principle: During cable stripping, the blades wear down and become dull as the stripping process continues. Existing cable stripping devices lack a corresponding sharpening mechanism, leading to continuous blade wear and dulling, reduced sharpness, and dull blades that can cause incomplete stripping or damage to the internal conductors of the cable, thus affecting the stripping quality. Therefore, a cable stripping device is proposed to address these issues. When stripping cables, the cable first enters the housing 4 through the threading hole 21. Then, the cable is conveyed to the stripping mechanism by a limiting conveying mechanism. The first pneumatic cylinder 5 is activated, causing the first pneumatic rod to move the blades 7 into the cable insulation. As the cable passes between the four blades 7, the high-speed rotation of the blades 7 cuts the cable insulation. After cutting, the cut insulation is easily removed from the cable, thus completing the stripping process. Cable stripping: As the stripping operation continues, the blades will gradually wear down and become dull. To prevent the blades 7 from becoming dull, a sharpening mechanism is set up. The second motor 10 is started, causing the bidirectional lead screw 11 to rotate. With the cooperation of the limit rod 14 and the limit block 15, the two movable blocks 12 drive the two grinding stones 13 to move steadily closer to each other until the two grinding stones 13 move to contact the surface of the blades 7. As the blades 7 rotate at a uniform speed, the grinding stones 13 help to grind the blades 7 evenly and effectively, thereby restoring their sharpness. Through the continuous sharpening of the sharpening mechanism, the blades can always remain sharp. Sharp blades can strip the cable sheath more accurately, reducing the possibility of sheath residue or damage to the internal conductor, thereby improving the stripping quality. At the same time, the sharpening mechanism can ensure that the blades maintain a consistent sharpness throughout the stripping process, thereby ensuring the consistency and reliability of the stripping operation.
