Description

Technical Field

[0001] This utility model relates to the field of wire stripper technology, and more specifically, to a low-voltage power distribution network cable stripper. Background Technology

[0002] In existing technologies, low-voltage power distribution network cable strippers typically face several problems, particularly during cable stretching, where tension is difficult to adjust and cable securing and stripping operations are not convenient. Specifically, maintaining appropriate tension during cable stretching is crucial for smooth stripping; however, traditional equipment often lacks precise tension adjustment capabilities, leading to potentially excessive or insufficient tension during the stretching process. This can affect stripping effectiveness, and may even damage the cable's outer layer or result in uneven stripping.

[0003] In addition, existing wire strippers have inconveniences when fixing cables. Traditional fixing devices mostly use manual clamping or mechanical clamps. This design usually results in the cable not being firmly fixed and is prone to slipping or shifting during the stripping process. Especially when dealing with long or thick cables, the insecure fixing not only affects the accuracy of the operation, but also increases the labor intensity and reduces the work efficiency.

[0004] In addition, the wire stripper's stripping operation sometimes lacks sufficient flexibility. For example, when faced with cables of different specifications and materials, the existing equipment may need to be adjusted frequently or cannot quickly adapt to different cable types and needs, resulting in inconvenience and wasted time and effort.

The roller pulling mechanism includes a drive motor, a mounting frame, a main shaft, a driven shaft, a main tooth, and a driven tooth. The drive motor and the mounting frame are mounted on the base frame. The main shaft and the driven shaft are rotatably mounted on the mounting frame. The main shaft is connected to the drive motor. The driven shaft clamps the cable on the main shaft. The main tooth and the driven tooth are mounted at one end of the main shaft and the driven shaft, and the main tooth and the driven tooth mesh with each other. The clamping stripping mechanism includes a stripping tube, a limiting tooth, a helical tooth plate, a mounting groove, a fitting sleeve, and a razor.

[0009] The present invention is further configured such that the wire stripping auxiliary mechanism includes a threaded ring, a friction ring, a rotating block, a bottom fixing plate, a tightening block, and a tightening spring. The rotating block is installed at the bottom end of the limiting tooth, the bottom fixing plate is installed at the bottom end of the wire stripping tube, and multiple sets of tightening blocks are slidably installed at the top end of the bottom fixing plate. The tightening spring connects adjacent tightening blocks, and the rotating block passes between two sets of tightening blocks in sequence, so that the limiting tooth can rotate stably. The threaded ring is threadedly connected to the outer wall of the clamping tube, and the friction ring is installed at the bottom end of the threaded ring. The friction ring presses against the top end of the limiting tooth, fixing the limiting tooth in the rotation direction.

[0010] The present invention is further configured such that a protective shell is installed at the top end of the base frame, and the protective shell is installed at the outer end of the main tooth and the driven tooth. The protective shell protects the main tooth and the driven tooth, prevents the operator from accidentally touching them, and improves safety.

[0011] The present invention is further configured such that a transmission belt assembly is installed at the output end of the drive motor, and the other end of the transmission belt assembly is connected to the main shaft. The transmission belt assembly buffers the load impact and reduces mechanical wear.

[0012] The present invention is further configured such that a longitudinal plate is installed at the top end of the base frame, and a through groove is opened on the longitudinal plate. A wire stripper is installed on the longitudinal plate, and an external cable passes through the wire stripper and the through groove in sequence to connect with the main shaft.

[0013] The present invention is further configured such that a connecting plate is installed at the bottom end of the side wall of the stripping tube, and the connecting plate is fixedly installed on one end face of the longitudinal plate, and the stripping tube is connected to the through groove. The setting of the connecting plate facilitates the stable installation of the stripping tube.

[0014] The present invention is further configured such that a centripetal rail is installed at the top end of the bottom fixing plate, and the tightening block is configured to slide centripetally on the centripetal rail. The configuration of the centripetal rail facilitates the clamping action of the tightening block.

[0015] The present invention is further configured such that a directional bearing is installed at the bottom end of the threaded ring, and the bottom end of the directional bearing is in contact with the top end of the friction ring.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a low-voltage power distribution network cable stripper, which has the following advantages:

[0018] This utility model is equipped with a roller pressing and pulling mechanism. The main shaft is driven to rotate by a drive motor. The driven shaft and the main shaft clamp the cable together to achieve stable cable pulling. The meshing transmission between the main teeth and the driven teeth ensures synchronous transmission between the main shaft and the driven shaft, improving the stability of cable conveying. The main teeth and the driven teeth are equipped with protective shells to effectively prevent operators from accidentally touching the rotating parts and improve safety.

[0019] This utility model features a clamping and stripping mechanism. A toothed plate inside the stripping tube, in conjunction with a fitting sleeve, rotates and clamps the cable, enabling the razor to perform precise stripping operations with higher quality. The limiting teeth and the toothed plate engage in a ring, stabilizing the plate's rotation and improving clamping consistency during stripping. The stripping assembly is integrated within the stripping tube, resulting in a compact structure that facilitates quick positioning and stripping, improving overall work efficiency. The fitting sleeve, working with the toothed plate, automatically adjusts the clamping force to adapt to the stripping needs of cables of different specifications.

[0020] This invention features a wire stripping auxiliary mechanism with multiple sets of tightening blocks that slide in conjunction with tightening springs and radial rails, making the rotation of the limiting teeth more stable and controlled, preventing deviation during wire stripping. The friction ring and threaded ring work together, with the cooperation of a directional bearing, to precisely limit the rotation direction of the limiting teeth, preventing misoperation. The threaded ring can adjust the friction clamping force by rotating, indirectly controlling the rotation damping of the limiting teeth and the rotary tooth plate, thus fixing the clamping force.

[0030] Please see Figures 1-5A low-voltage power distribution network cable stripper includes a base frame 1, a roller pressing and pulling mechanism, a clamping and stripping mechanism, and a stripping auxiliary mechanism. The roller pressing and pulling mechanism includes a drive motor 2, a mounting frame 3, a main shaft 4, a driven shaft 5, a main gear 6, and a driven gear 7. The drive motor 2 and the mounting frame 3 are mounted on the base frame 1. The main shaft 4 and the driven shaft 5 are rotatably mounted on the mounting frame 3. The main shaft 4 is connected to the drive motor 2. The driven shaft 5 clamps the cable on the main shaft 4. The main gear 6 and the driven gear 7 are installed at one end of the main shaft 4 and the driven shaft 5. The tooth 6 is engaged with the tooth 7. The clamping and stripping mechanism includes a stripping tube 8, a limiting tooth 9, a spiral tooth plate 10, a mounting groove 11, a fitting sleeve 12, and a razor 13. The limiting tooth 9 is rotatably mounted on the outer wall of the stripping tube 8. The mounting groove 11 is set on the stripping tube 8. The spiral tooth plate 10 is rotatably mounted in the mounting groove 11. The spiral tooth plate 10 is circumferentially engaged with the limiting tooth 9. The fitting sleeve 12 is mounted on one end of the spiral tooth plate 10. The rotating fitting sleeve 12 clamps the cable. The razor 13 is mounted on the top end of the fitting sleeve 12.

[0031] In this embodiment, the roller pulling mechanism is the power source and cable transmission part of the entire wire stripper. The drive motor 2 drives the main shaft 4 to rotate through the transmission belt assembly 21. The main gear 6 on the main shaft 4 meshes with the driven gear 7 on the driven shaft 5, driving the driven shaft 5 to rotate synchronously. The main shaft 4 and the driven shaft 5 form a pair of rollers. When the cable is placed between the two shafts, the two shafts cooperate to clamp the cable, ensuring the stability and consistency of cable transportation. When the cable passes through the stripping tube 8, the user operates the rotation of the limiting gear 9, which drives the rotary tooth plate 10 to rotate in the mounting groove 11. The fitting sleeve 12 connected to the rotary tooth plate 10 rotates accordingly, firmly clamping the cable. The razor 13 at the top end of the fitting sleeve 12 precisely cuts the cable sheath while the cable moves, realizing the stripping function. Throughout the process, the meshing of the limiting gear 9 and the rotary tooth plate 10 ensures the precise control of the stripping action.

[0032] The wire stripping auxiliary mechanism includes a threaded ring 14, a friction ring 15, a rotating block 16, a bottom fixing plate 17, a tightening block 18, and a tightening spring 19. The rotating block 16 is installed at the bottom end of the limiting tooth 9, and the bottom fixing plate 17 is installed at the bottom end of the wire stripping tube 8. Multiple sets of tightening blocks 18 are slidably installed at the top end of the bottom fixing plate 17. The tightening spring 19 holds adjacent tightening blocks 18 together, and the rotating block 16 passes between two sets of tightening blocks 18 in sequence, so that the limiting tooth 9 can rotate stably. The threaded ring 14 is threadedly connected to the outer wall of the clamping tube. The friction ring 15 is installed at the bottom end of the threaded ring 14 and presses against the top end of the limiting tooth 9 to fix the limiting tooth 9 in the rotation direction.

[0033] In this embodiment, the wire stripping accuracy is improved through precise pressure control and rotation stabilization mechanism. The rotating block 16 at the bottom of the limiting tooth 9 passes between the tightening blocks 18. The tightening spring 19 keeps the tightening block 18 under appropriate radial pressure. The centripetal rail 25 on the bottom plate 17 guides the centripetal sliding of the tightening block 18, ensuring the stable rotation of the limiting tooth 9 ring and realizing the stable wrapping of the cable by the fitting sleeve 12. At this time, the threaded ring 14 can be adjusted on the outer wall of the stripping tube 8. The friction ring 15 at the bottom applies pressure to the limiting tooth 9, fixing the limiting tooth 9 in the rotation direction, so that the fitting sleeve 12 and the razor 13 are stably wrapped on the outside of the cable.

[0034] Please see Figures 1-5 As a supplementary embodiment of a low-voltage power distribution network cable stripper comprising a roller pressing mechanism, a clamping stripping mechanism, and a stripping auxiliary mechanism: A protective shell 20 is installed at the top end of the base frame 1, and the protective shell 20 is installed on the outer ends of the main teeth 6 and the driven teeth 7. A transmission belt assembly 21 is installed at the output end of the drive motor 2, and the other end of the transmission belt assembly 21 is connected to the main shaft 4. A longitudinal plate 22 is installed at the top end of the base frame 1, and a through groove 23 is opened on the longitudinal plate 22. The stripping tube 8 is installed on the longitudinal plate 22. External cables pass through the stripping tube 8 and the through groove 23 in sequence and are connected to the main shaft 4. A connecting plate 24 is installed at the bottom end of the side wall of the stripping tube 8, and the connecting plate 24 is fixedly installed on one end face of the longitudinal plate 22. The stripping tube 8 is connected to the through groove 23. A radial rail 25 is installed at the top end of the bottom fixed plate 17, and the tightening block 18 is slidably mounted on the radial rail 25. A directional bearing 26 is installed at the bottom end of the threaded ring 14, and the bottom end of the directional bearing 26 is in contact with the top end of the friction ring 15.

[0035] More specifically, the cable is inserted through one end of the stripping tube 8, and then passes through the slot 23 between the main shaft 4 and the driven shaft 5. The drive motor 2 is started to rotate the main shaft 4, and the main gear 6 drives the driven gear 7 to rotate. The main shaft 4 and the driven shaft 5 clamp the cable, and the fitting sleeve 12 rotates to fix the cable. The cable moves forward at a constant speed under the action of the rollers. The razor 13 on the top of the fitting sleeve 12 cuts into the cable sheath. The limiting tooth 9 and the rotary tooth plate 10 control the stripping depth. The stripping tube 8 guides the direction of cable movement. The tightening block 18 slides on the centripetal rail 25. The tightening spring 19 maintains the tension between the tightening blocks 18. The rotating block 16 passes through the tightening block 18 to provide stability. The cable sheath is precisely cut by the razor 13. The rollers continue to pull the cable forward. After the stripping is completed, the drive motor 2 is stopped, and the stripped cable is taken out.

[0036] In summary, when the overall equipment is in use or running: when the roller pressing and pulling mechanism is required to run, the roller pressing and pulling mechanism is the power source and cable transmission part of the entire wire stripper. The drive motor 2 drives the main shaft 4 to rotate through the transmission belt assembly 21. The main gear 6 on the main shaft 4 meshes with the driven gear 7 on the driven shaft 5, driving the driven shaft 5 to rotate synchronously. The main shaft 4 and the driven shaft 5 form a pair of rollers. When the cable is placed between the two shafts, the two shafts cooperate to clamp the cable, ensuring the stability and consistency of cable transportation.

[0037] When the wire stripping mechanism is in operation, it is responsible for the actual cable stripping operation. When the cable passes through the stripping tube 8, the user operates the rotation of the limiting tooth 9, which drives the rotary tooth plate 10 to rotate in the mounting groove 11. The fitting sleeve 12 connected to the rotary tooth plate 10 rotates accordingly, firmly clamping the cable. The razor 13 at the top of the fitting sleeve 12 precisely cuts the cable sheath while the cable moves, realizing the wire stripping function. Throughout the process, the meshing of the limiting tooth 9 and the rotary tooth plate 10 ensures precise control of the wire stripping action.

[0038] When the wire stripping auxiliary mechanism is in operation, the wire stripping accuracy is improved through precise pressure control and rotation stabilization mechanism. The rotating block 16 at the bottom of the limiting tooth 9 passes between the tightening blocks 18. The tightening spring 19 keeps the tightening block 18 under appropriate radial pressure. The centripetal rail 25 on the bottom plate 17 guides the centripetal sliding of the tightening block 18 to ensure the stable rotation of the limiting tooth 9 ring and realize the stable wrapping of the cable by the fitting sleeve 12. At this time, the threaded ring 14 can be adjusted on the outer wall of the stripping tube 8. The friction ring 15 at the bottom applies pressure to the limiting tooth 9 to fix the limiting tooth 9 in the rotation direction, so that the fitting sleeve 12 and the razor 13 are stably wrapped on the outside of the cable.

[0039] The cable is inserted into one end of the stripping tube 8 and passes through the slot 23 between the main shaft 4 and the driven shaft 5. The drive motor 2 is started to drive the main shaft 4 to rotate, and the main gear 6 drives the driven gear 7 to rotate. The main shaft 4 and the driven shaft 5 clamp the cable, and the fitting sleeve 12 rotates to fix the cable. The cable moves forward at a constant speed under the action of the rollers. The razor 13 on the top of the fitting sleeve 12 cuts into the cable sheath. The limiting tooth 9 and the rotary tooth plate 10 control the stripping depth. The stripping tube 8 guides the direction of cable movement. The tightening block 18 slides on the centripetal rail 25. The tightening spring 19 maintains the tension between the tightening blocks 18. The rotating block 16 passes through the tightening block 18 to provide stability. The cable sheath is precisely cut by the razor 13. The rollers continue to pull the cable forward. After the stripping is completed, the drive motor 2 is stopped, and the stripped cable is taken out.
