Description

Technical Field

[0001] The invention relates to the technical field of cable stripping, in particular to a stripping device for laying power cables. Background Art

[0002] Cable is an insulated wire composed of one or more mutually insulated conductive cores wrapped in a sealed sheath. The sealed sheath may be covered with a protective covering layer. It is used to transmit and distribute electrical energy or transmit electrical signals. The main difference between it and ordinary wires is that the cable is larger in size and more complex in structure. Cables are mostly used for multiple functions such as control installation, connecting equipment, and transmitting electricity. Cable laying is cable laying. Long-distance communication cables are generally laid directly in burial to ensure safe and reliable communication; urban trunk cables (relay and user trunk cables) are generally laid in pipelines to ensure safe and reliable communication, convenient installation and replacement, and beautiful city appearance; urban distribution cables can be laid overhead and on walls. With the development of modern urban construction, they will gradually be replaced by pipeline laying.

[0003] The existing cable stripping device cannot accurately adjust more than two cutters through one operation step, resulting in a long adjustment time for the cutters and the adjusted position of the cutters easily deviates from the original direction, further resulting in reduced cable stripping efficiency. At the same time, the insulation thickness of cables of different diameters is different, and cutting the cutter too deep will damage the metal core inside the cable. Summary of the invention

[0006] Preferably, the ring cutting assembly includes a square plate, which is located inside the arc groove and between the two fixed rings. A through hole is opened in the middle of the square plate, and a fixed rod is located inside the through hole. The fixed rod is slidably connected to the square plate through the through hole, and the end of the cable with the stripped wire is sent into the interior of the shell. After the ring cutting position is determined, the motor is connected to an external power supply, and the motor drives the connecting piece to rotate forward, so that the connecting piece drives the circular ring to rotate inside the two fixed rings. At this time, the roller slides inside the arc groove, and the roller drives the square plate to move toward the middle of the circular ring under the action of the extrusion force of the arc groove. Thereby, the fan-shaped plate drives the bottom blade to approach the cable in the middle, so that the bottom side of the fan-shaped plate fits the cable, and then by rotating the ring, more than two tools can be accurately adjusted through one operation step, so that the adjustment time of the tool is short and the position of the tool after adjustment will not deviate from the original direction, further improving the cable stripping efficiency. A roller is rotatably connected to one side of the square plate close to the arc groove, and the roller is slidably connected to the arc groove. The end of the square plate away from the roller is fixedly connected to the fan-shaped plate, and a movable groove is opened inside the fan-shaped plate, and the blade is located inside the movable groove.

[0007] Preferably, a spring plate is fixedly connected to the outer edge of the fixing ring, the spring plate is inclined, the inclination direction of the spring plate is consistent with the direction of the arc groove, the spring plate is located in the middle of the two fixing rings, there are multiple spring plates, the number of teeth of the multiple spring plates is consistent with the number of teeth of the circular ring, the fan-shaped plate contacts the cable, when the motor drives the connecting piece to rotate forward, the gear drives the circular ring to rotate, at this time the block contacts the spring plate at the edge of the fixing ring, the spring plate is compressed and deformed by force, so that the block passes through the spring plate, and the gear does not drive the fixing ring to rotate, thereby adjusting the ring cutting assembly, when the motor drives the connecting piece to rotate in the opposite direction, at this time the block contacts the spring plate, the spring plate is deformed by force of the pull rope, so that the block drives the fixing ring to rotate, at this time the wire stripping assembly performs ring cutting on the cable, because the circular ring and the fixing ring are relatively stationary, the ring cutting assembly does not move, the fixing rod is fixedly connected to a round rod away from the outer side of the spring plate, the round rod is fixedly connected to the blade at one end away from the fixing rod, and the arc groove is fixed away from the inner wall of the ring cutting assembly The outer side of the U-shaped plate is rotatably connected to the inner side of the fixing ring, and the inner side of the U-shaped plate is slidably connected to the fixing block and the U-shaped plate, so that the U-shaped plate slides on the inner side of the fixing ring.

[0008] Preferably, a side plate is fixedly connected to the outer side of the square plate, and the side plate is semi-elliptical. There are two side plates, which are symmetrically arranged with the square plate as the center. The blade is slidably connected to the fan-shaped plate through a movable groove. A circular hole is opened at one end of the square plate close to the fan-shaped plate. By setting a round rod, during the adjustment process, the square plate moves toward the middle, so that the square plate drives the fan-shaped plate to move, so that the length of the blade exceeding the fan-shaped plate becomes shorter, so that the depth of the blade can be adjusted according to cables of different diameters to prevent the blade from being too shallow and possibly failing to completely penetrate the insulation layer, resulting in incomplete wire stripping. The blade is too deep and causes damage to internal components. The circular hole penetrates the fan-shaped plate, and the circular hole is connected to the through hole, and the round rod is located inside the circular hole.

[0009] The connecting part includes a gear, which is fixedly connected to the output end of the motor. The gear is located inside the fixed frame and is rotatably connected to the outer side of the ring. A ring groove is provided at the outer edge of the gear, and blocks are fixedly connected to the inner wall of the ring groove. The number of blocks is consistent with the number of teeth on the gear.

[0010] Preferably, the shell includes an outer shell, which is fixedly connected to the base, and the outer shell is fixedly connected to a fixing frame near the bottom of the motor, the connecting piece is located inside the fixing frame, and the outer shell is fixedly connected to an intermediate ring near the inner wall of the ring cutting assembly, and a slide groove is opened on the inner wall of the outer shell. Cables with larger diameters have thicker insulation layers. Cables with thicker insulation layers need to have more insulation layers stripped off to expose sufficient conductors for connection. The stripped cable is fed into the interior of the outer shell, and the cable passes through the stripping assembly into the interior of the conical cylinder. Since the conical cylinder is elastic at one end near the through groove, when the cable diameter is the same as the minimum diameter of the conical cylinder, the cable directly passes through the conical cylinder and the end contacts the baffle. When the cable diameter is larger than the minimum diameter of the conical cylinder, the cable is squeezed against the inner wall of the conical cylinder, and the end of the conical cylinder near the baffle is deformed and expanded outward. At this time, the extension cylinder and the bracket move in the direction away from the conical cylinder inside the slide groove under the action of the extrusion force. At this time, the length of the cable that can enter the interior of the outer shell is The increase makes it possible to adjust the length of the cable stripping according to the diameter of the cable, and the bracket is slidably connected to the inside of the slide slot, and the middle ring is fixedly connected to the conical cylinder at one end near the slide slot, and the bracket is fixedly connected to the outside of the conical cylinder near the extension cylinder, and the end of the extension cylinder near the conical cylinder is set to be hook-shaped, and the end of the conical cylinder away from the middle ring is fixedly connected to an extension block.

After the ring cutting is completed, the cable is taken out and the conical cylinder is reset. Under the elastic force of the elastic rope, the extension cylinder is reset, and when the conical cylinder is close to the middle ring, a through groove is provided, and the through grooves are evenly distributed with the conical cylinder as the center, and the outer side of the extension block is fixedly connected to an elastic rope. In the initial state, the elastic rope is in a taut state, and a feeding hole is opened inside the shell, and the feeding hole is located at the bottom of the shell, and the end of the bracket away from the extension cylinder is fixedly connected to a baffle, and the elastic rope is fixedly connected to the edge of the baffle.

[0011] The present invention provides a wire stripping device for laying power cables. It has the following beneficial effects:

[0012] 1. The wire stripping device for laying power supply cables can accurately adjust two or more cutters through one operation step by rotating a ring, so that the adjustment time of the cutters is short and the positions of the cutters after adjustment will not deviate from the original directions, further improving the cable stripping efficiency.

[0013] 2. The wire stripping equipment for laying power supply cables has a sawtooth blade. The sawtooth design enables the blade to act simultaneously with multiple small cutting points when contacting the cable insulation layer, which can greatly improve the efficiency of wire stripping. At the same time, the presence of sawtooth increases the friction between the blade and the insulation layer, making it less likely for the blade to slip when cutting the cable.

[0014] 3. The wire stripping equipment for laying power supply cables uses a round rod. During the adjustment process, the square plate moves toward the middle, so that the square plate drives the fan-shaped plate to move, so that the length of the blade exceeding the fan-shaped plate becomes shorter, so that the depth of the blade can be adjusted according to cables of different diameters to prevent the blade from being too shallow and possibly failing to completely penetrate the insulation layer, resulting in incomplete stripping. The blade is too deep and causes damage to internal components.

[0015] Fourth, the wire stripping equipment for laying power supply cables expands outwardly through the deformation of the conical cylinder, so that the extension cylinder and the bracket move away from the conical cylinder inside the slide groove under the action of the extrusion force, thereby increasing the length of the cable that can enter the shell, and then the length of the cable stripping can be adjusted according to the diameter of the cable.

DETAILED DESCRIPTION

[0028] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0029] The first embodiment, as Figures 1 to 8As shown, the present invention provides a technical solution: a wire stripping device for laying power supply cables, comprising a base 1, the base 1 is L-shaped, the top of the base 1 is fixedly connected to a shell 2, the shell 2 is located at the top of the side of the base 1, a motor 3 is arranged on the outside of the shell 2, the motor 3 is fixedly installed on the top of the base 1, and the output end of the motor 3 passes through the shell 2 and extends to the inside; a wire stripping assembly 5, the wire stripping assembly 5 is rotatably connected to the inside of the shell 2, and the wire stripping assembly 5 is located on a side of the shell 2 close to the motor 3; a connecting member 4, the connecting member 4 is fixedly connected to the output end of the motor 3, the connecting member 4 is located inside the shell 2, and the connecting member 4 is rotatably connected to the wire stripping assembly 5, and the connecting member 4 and the wire stripping assembly 5 are located on the same vertical plane; wherein the wire stripping assembly 5 comprises a fixing ring 51, the fixing ring 51 is rotatably connected to the shell 2, there are two fixing rings 51, and circular rings 52 are arranged on opposite sides of the two fixing rings 51, The circular ring 52 is rotatably connected to the two fixed rings 51 on both sides. An arc groove 53 is opened inside the circular ring 52. There are three arc grooves 53, which are evenly distributed around the circular ring 52. The outer side of the circular ring 52 is toothed, and the circular ring 52 is gear-engaged with the connecting member 4. A ring cutting component 54 is slidably connected inside the circular ring 52. A fixing rod 57 is fixedly connected to the outer side of the fixing ring 51 close to the ring cutting component 54. A blade 511 is arranged on the side of the ring cutting component 54 away from the circular ring 52. The blade 511 is serrated. The serrated design enables the blade 511 to act at multiple small cutting points simultaneously when contacting the cable insulation layer, which can greatly improve the efficiency of wire stripping. At the same time, the presence of the serrations increases the friction between the blade 511 and the insulation layer, so that the blade 511 is not easy to slip when ring cutting the cable, reducing the risk of uneven cutting or damage to the internal conductor due to slipping.The ring cutting assembly 54 includes a square plate 541, which is located inside the arc groove 53 and between the two fixing rings 51. A through hole 542 is provided in the middle of the square plate 541. A fixing rod 57 is located inside the through hole 542. The fixing rod 57 is slidably connected to the square plate 541 through the through hole 542. The end of the cable with the stripped wire is sent into the interior of the housing 2. After the ring cutting position is determined, the motor 3 is connected to an external power supply, and the motor 3 drives the connecting member 4 to rotate forward, so that the connecting member 4 drives the circular ring 52 to rotate inside the two fixing rings 51. At this time, the roller 547 slides inside the arc groove 53. Under the action of the squeezing force of the arc groove 53, the roller 547 drives the square plate 541 toward the center of the circular ring 52. The fan-shaped plate 544 drives the bottom blade 511 to approach the cable in the middle, so that the bottom side of the fan-shaped plate 544 fits the cable, and then the ring 52 can be rotated to accurately adjust more than two knives through one operation step, so that the adjustment time of the knives is short and the position of the knives after adjustment will not deviate from the original direction, further improving the cable stripping efficiency. The side of the square plate 541 close to the arc groove 53 is rotatably connected with a roller 547, and the roller 547 is slidably connected to the arc groove 53. The end of the square plate 541 away from the roller 547 is fixedly connected with the fan-shaped plate 544, and a moving groove 546 is opened inside the fan-shaped plate 544, and the blade 511 is located inside the moving groove 546. ;

[0030] The second embodiment is based on the first embodiment. Fig. 9As shown, a spring plate 56 is fixedly connected to the outer edge of the fixing ring 51, and the spring plate 56 is inclined. The inclination direction of the spring plate 56 is consistent with the direction of the arc groove 53. The spring plate 56 is located in the middle of the two fixing rings 51. There are multiple spring plates 56, and the number of teeth of the multiple spring plates 56 is consistent with that of the circular ring 52. The fan-shaped plate 544 contacts the cable. When the motor 3 drives the connecting member 4 to rotate forward, the gear 41 drives the circular ring 52 to rotate. At this time, the block 43 contacts the spring plate 56 at the edge of the fixing ring 51, and the spring plate 56 is compressed and deformed by force, so that the block 43 passes through the spring plate 56, and the gear 41 does not drive the fixing ring 52. The ring 51 rotates, thereby adjusting the ring cutting assembly 54. When the motor 3 drives the connecting piece 4 to rotate in the opposite direction, the block 43 contacts the spring plate 56, and the spring plate 56 is deformed by the pulling rope, so that the block 43 drives the fixed ring 51 to rotate. At this time, the wire stripping assembly 5 performs ring cutting on the cable. Since the circular ring 52 and the fixed ring 51 are relatively still, the ring cutting assembly 54 does not move. The outer side of the fixed rod 57 away from the spring plate 56 is fixedly connected to the round rod 58. One end of the round rod 58 away from the fixed rod 57 is fixedly connected to the blade 511. The inner wall of the arc groove 53 away from the ring cutting assembly 54 is fixedly connected to a fixed block 55, the top of the fixing block 55 is flush with the inner side of the fixing ring 51, and the top of the fixing block 55 is fixedly connected with a U-shaped plate 59. The cylinder 510 is magnetic, and the cylinders 510 located on the two inner sides of the U-shaped plate have opposite magnetic properties. The connecting member 4 drives the ring 52 to rotate, and the ring 52 drives the fixing block 55 and the U-shaped plate 59 to rotate, so that the U-shaped plate 59 slides on the inner side of the fixing ring 51. At this time, the square plate 541 is located inside the U-shaped plate 59, and there is extrusion between the square plate 541 and the cylinder 510. The cylinder 510 is forced to move in a direction away from the square plate 541, so that the fan-shaped plate 544 is close to the outer side of the cable. When the circular ring 52 contacts the side, it stops rotating. The mutual attraction between the cylinders 510 on both sides is used to move the cylinder 510 toward the direction of the square plate 541, so that the cylinder 510 is located in the middle of the side plate 543 and the square plate 541. At this time, the circular cutting assembly 54 is limited and self-locked by the cylinder 510 and the arc groove 53 to prevent the fan-shaped plate 544 and the blade 511 from being separated from the cable during operation, thereby affecting the wire stripping effect. The outer side of the U-shaped plate 59 is rotatably connected to the inner side of the fixed ring 51, and the inner side of the U-shaped plate 59 is slidably connected to the cylinder 510. The cylinder 510 is symmetrically arranged with the fixed block 55 as the center.

[0031] The outer side of the square plate 541 is fixedly connected to a side plate 543, which is semi-elliptical. There are two side plates 543, and the two side plates 543 are symmetrically arranged with the square plate 541 as the center. The blade 511 is slidably connected to the fan-shaped plate 544 through a movable groove 546. A circular hole 545 is provided at one end of the square plate 541 close to the fan-shaped plate 544. By setting a round rod 58, during the adjustment process, the square plate 541 moves toward the middle, so that the square plate 541 drives the fan-shaped plate 544 to move, so that the length of the blade 511 exceeding the fan-shaped plate 544 becomes shorter, so that the depth of the blade 511 can be adjusted according to cables of different diameters to prevent the blade from being too shallow and possibly failing to completely penetrate the insulation layer, resulting in incomplete wire stripping. The blade is too deep and causes damage to the internal components. The circular hole 545 penetrates the fan-shaped plate 544, and the circular hole 545 is connected to the through hole 542, and the round rod 58 is located inside the circular hole 545.

[0032] The connecting member 4 includes a gear 41, which is fixedly connected to the output end of the motor 3. The gear 41 is located inside the fixed frame 22. The gear 41 is rotatably connected to the outer side of the ring 52. An annular groove 42 is provided at the outer edge of the gear 41. The inner wall of the annular groove 42 is fixedly connected with a block 43. The number of blocks 43 is consistent with the number of teeth of the gear 41.

[0033] The third embodiment is based on the first and second embodiments. Figure 10 to Figure 11As shown, the housing 2 includes a shell 21, the shell 21 is fixedly connected to the base 1, the shell 21 is fixedly connected to a fixing frame 22 near the bottom of the motor 3, the connecting member 4 is located inside the fixing frame 22, the shell 21 is fixedly connected to an intermediate ring 23 near the inner wall of the ring cutting component 54, and the inner wall of the shell 21 is provided with a slide groove 25. The cable with a larger diameter has a thicker insulation layer. The cable with a thicker insulation layer needs to strip off a longer length of insulation layer to expose enough conductors for connection. The cable with stripped wire is fed into the shell 21, and the cable passes through the stripping component 5 and enters the inside of the conical cylinder 24. Due to the conical cylinder The end of the conical cylinder 24 near the through groove 212 is elastic. When the cable diameter is the same as the minimum diameter of the conical cylinder 24, the cable directly passes through the conical cylinder 24, and the end contacts the baffle 211. When the cable diameter is larger than the minimum diameter of the conical cylinder 24, the cable and the inner wall of the conical cylinder 24 are squeezed, and the end of the conical cylinder 24 near the baffle 211 is deformed and expanded outward. At this time, the extension cylinder 28 and the bracket 26 move in the direction away from the conical cylinder 24 inside the slide groove 25 under the action of the squeezing force. At this time, the length of the cable that can enter the shell 21 increases, so that the cable can be adjusted according to the length of the cable. The length of the cable stripping is adjusted by adjusting the diameter. The bracket 26 is slidably connected inside the slide groove 25. The end of the intermediate ring 23 close to the slide groove 25 is fixedly connected to the conical cylinder 24. The bracket 26 is fixedly connected to the outer side of the conical cylinder 24. The end of the extension cylinder 28 close to the conical cylinder 24 is set to be hook-shaped. The end of the conical cylinder 24 away from the intermediate ring 23 is fixedly connected to an extension block 27. During adjustment, when the extension cylinder 28 moves outward for a certain distance, the extension block 27 contacts with the hook-shaped end of the extension cylinder 28 and is snap-fitted to prevent the extension cylinder 28 from separating from the conical cylinder 24. After the circumcision is completed, The cable is taken out, and the conical cylinder 24 is reset. Under the elastic force of the elastic rope 29, the extension cylinder 28 is reset. A through groove 212 is provided at one end of the conical cylinder 24 close to the middle ring 23. The through grooves 212 are evenly distributed with the conical cylinder 24 as the center. The outer side of the extension block 27 is fixedly connected with the elastic rope 29. In the initial state, the elastic rope 29 is in a taut state. A discharge hole 210 is opened inside the outer shell 21. The discharge hole 210 is located at the bottom of the outer shell 21. A baffle 211 is fixedly connected to the end of the bracket 26 away from the extension cylinder 28, and the elastic rope 29 is fixedly connected to the edge of the baffle 211.

[0034] When in use, the cable with stripped wire is fed into the interior of the housing 21, and the cable passes through the stripping assembly 5 and enters the interior of the conical cylinder 24. Since the conical cylinder 24 is elastic at one end close to the through groove 212, when the cable diameter is the same as the minimum diameter of the conical cylinder 24, the cable directly passes through the conical cylinder 24, and the end contacts the baffle 211. When the cable diameter is larger than the minimum diameter of the conical cylinder 24, the cable and the inner wall of the conical cylinder 24 are squeezed, and the end of the conical cylinder 24 close to the baffle 211 is deformed and expanded outward. At this time, the extension cylinder 28 and the bracket 26 move in the direction away from the conical cylinder 24 inside the slide groove 25 under the action of the squeezing force. At this time, the length of the cable that can enter the interior of the housing 21 is increased, so that the length of the cable stripping can be adjusted according to the diameter of the cable.

[0035] After the cable is placed and the ring cutting position is determined, the motor 3 is connected to an external power supply and starts to work. The motor 3 drives the connecting piece 4 to rotate in the forward direction, so that the connecting piece 4 drives the circular ring 52 to rotate inside the two fixed rings 51. At this time, the roller 547 slides inside the arc groove 53. Under the action of the squeezing force of the arc groove 53, the roller 547 drives the square plate 541 to move toward the middle of the circular ring 52, so that the fan-shaped plate 544 drives the bottom blade 511 to approach the middle of the cable, so that the bottom side of the fan-shaped plate 544 fits with the cable. When the motor 3 drives the connecting piece 4 to rotate in the opposite direction, the block 43 contacts the spring plate 56, and the spring plate 56 is deformed by the pulling rope, so that the block 43 drives the fixed ring 51 to rotate. At this time, the wire stripping assembly 5 performs a ring cutting on the cable.

[0036] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
