Description

Technical Field

[0001] This invention relates to the field of cable processing equipment technology, specifically to a cable stripping device for cable production that avoids scratching the wire core. Background Technology

[0002] As a key medium for transmitting electricity or signals, cables have an extremely wide range of applications, from household electricity to industrial automation and complex communication networks. Various types of cables are indispensable. Since cables usually contain high-value metals such as copper and aluminum, if substandard products are found during the cable production process, the insulation layer is usually removed by a stripping device in order to recover the metal materials in the core, thereby achieving the reuse and conservation of raw materials.

[0003] However, during the process of stripping cables, if the device comes into contact with a hard core, it can easily scratch or even cut the internal metal conductor or optical fiber. This damage will reduce the effective cross-sectional area of ​​the metal, thereby affecting its conductivity. In severe cases, the damaged part needs to be completely removed, thereby reducing the quantity and quality of recyclable metal. Even slight scratches can lead to increased resistance, affecting the current transmission efficiency.

[0004] Therefore, the present invention proposes a stripping device for cable production that avoids scratching the wire core, in order to make up for and improve the shortcomings of the prior art. Summary of the Invention

[0005] In view of the deficiencies of the existing technology, the present invention provides a stripping device for cable production that avoids scratching the wire core, which can effectively solve the above-mentioned technical problems.

[0006] The technical implementation of this invention is as follows: A support frame is included, with multiple electric rollers slidably connected to both sides of the support frame. A drive assembly is provided on the inner side of each electric roller. A bidirectional lead screw is rotatably connected to one side at each end of the support frame. One end of each adjacent electric roller is threaded to the outer surface of the bidirectional lead screw. Material receiving components are fixedly connected to both sides of the bottom upper surface of the support frame. A rotating frame is rotatably connected to both sides of the middle of the support frame. A cutting component is slidably connected to the outer surface of the rotating frame in a ring shape. A second sliding frame is symmetrically slidably connected to the side of the rotating frame that is far apart from each other. A guide component is slidably connected to the outer surface of the side of the rotating frame that is far apart from each other. Multiple second connecting rods are rotatably connected to the outer surface of the second sliding frame in a ring shape. The other end of each second connecting rod is rotatably connected to the outer surface of both sides of the guide component. A pin is slidably connected to the side of the guide component that is close to each other, and the outer surface of the pin penetrates the inner side of the cutting component. After the cutting component moves downward and unlocks by the pin, when the cutting component encounters a harder internal wire core during cutting, the cutting component can automatically rise, thereby effectively preventing it from continuing to penetrate and scratch or cut the wire core.

[0007] More preferably, the outer surface of the rotating frame is fixedly connected with multiple guide frames in a ring shape. The ends of the guide frames that are far apart from each other are inclined. The inner sides of the ends of the guide frames that are far apart from each other are slidably connected with third sliding frames. The inner sides of the third sliding frames are fixedly connected to the outer surface of the pin. When the third sliding frames slide up and down in the inclined groove of the guide frames, the pin can automatically insert and release the cutting workpiece.

[0008] More preferably, the ends of the electric rollers that are far apart from each other are rotatably connected to a first connecting rod, and the ends of the adjacent first connecting rods that are close to each other are rotatably connected to a moving shaft. The two sides of the outer surface of the second sliding frame are symmetrically fixedly connected to the first sliding frame, and the other ends of the first sliding frame are rotatably connected to the outer surface of the moving shaft. When the adjacent electric rollers move to the side that are close to each other, the cutting piece can be automatically inserted into the insulation layer of the cable.

[0009] More preferably, each of the pins has a spring fixedly fitted onto its outer surface, and one end of each spring is fixedly connected to the outer surface of the third sliding frame. The spring can drive the cutting piece to reset and move when the cutting piece moves upward.

[0010] More preferably, the outer surfaces of the rotating frame on the sides close to each other are fixedly connected to gear discs, and the upper surface of one side of the support frame is fixedly connected to a protective shell. Spur gears are rotatably connected to both sides inside the protective shell, and the outer surfaces of the spur gears mesh with the outer surfaces of the gear discs. A first motor is fixedly connected to the upper surface of the bottom of the protective shell, and the output shaft of the first motor is connected through to the inner side of the protective shell. A first bevel gear is fixedly connected to the output shaft of the first motor. A second bevel gear is symmetrically fixedly connected to the side of the spur gears that are far apart from each other, and the outer surfaces of the first and second bevel gears mesh with each other. When the first motor rotates, the cutting parts on both sides will perform circular cuts on the cable in different directions, causing the torque generated during the cutting process to cancel each other out, thereby effectively preventing the cable from twisting during processing.

[0011] More preferably, a reciprocating screw is rotatably connected to one side of each receiving component that is close to the other. A push plate is threaded onto the outer surface of each reciprocating screw. The lower surface of the push plate at the end away from the reciprocating screw is slidably connected to the upper surface of the receiving component. A second motor is fixedly connected to one side of one of the receiving components. The output shaft of the second motor is fixedly connected to one end of one of the reciprocating screws. A belt is driven through the outer surface of the output shaft of the second motor. The end of the belt away from the second motor is driven through the outer surface of one end of the other reciprocating screw. As the push plate moves back and forth, the insulating waste material received inside the receiving component can be pushed out, effectively preventing the accumulation of waste material from affecting the normal operation of the equipment.

[0012] More preferably, the inner diameter of the rotating frame gradually increases on the opposite sides, which facilitates the discharge of waste materials.

[0013] More preferably, one end of each receiving component is rotatably connected to a rotating shaft, and a shielding cloth is fixedly wrapped around the outer surface of each rotating shaft. One end of each shielding cloth passes through one side of the receiving component and is fixedly connected to the upper surface of the push plate. When the shielding cloth is unfolded by the push plate, the upper surface of the shielding cloth can receive the waste material and effectively prevent the waste material from scattering.

[0014] More preferably, both ends of the rotating shaft are fixedly connected to a shielding cloth, and the ends of the shielding cloths that are far apart from each other are fixedly connected to the inner side of one end of the receiving component. The torsion spring can drive the shielding cloth to reset and rewind through the rotating shaft.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. When the cutting component is engaged by disengaging the pin, it automatically rises when encountering a hard internal wire core during the cutting operation, effectively preventing it from further penetrating and scratching or cutting the wire core, thus ensuring that the electrical performance and mechanical strength of the cable are not affected. When the pin is pulled out and inserted into the inside of the cutting component, it can stably insert into the insulation layer during the initial cutting stage, avoiding premature shrinkage due to unexpected factors. During the cutting process, after the pin is disengaged from the cutting component, it can achieve precise cutting, thus effectively protecting the internal wire core from damage.

[0017] 2. When the output shaft of the first motor rotates, the cutting components on both sides make circular cuts on the cable in different directions. This causes the torque generated during the cutting process to cancel each other out, thereby effectively preventing the cable from twisting during processing. The cable remains stable and centered during the cutting process, improving the smoothness and controllability of the cutting process. In addition, the cutting components act on the insulation layer from different directions at the same time, making the cutting force more evenly distributed on the circumference of the cable. This avoids local overcutting or eccentric cutting caused by excessive force on one side, thereby achieving a more uniform and stable cutting effect.

[0018] 3. When the reciprocating screw drives the push plate to move back and forth, the push plate can push out the insulation waste material inside the receiving part, effectively preventing the waste material from accumulating and affecting the normal operation of the equipment, and at the same time facilitating the centralized collection and recycling of waste material; when the push plate drives the shielding cloth to unfold, the falling waste material is caught by the shielding cloth, and during the reset movement of the shielding cloth, the waste material can be transported back into the receiving part, thereby effectively preventing the waste material from scattering.

Detailed Implementation

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Next, we will combine the appendix Figures 1-5 A specific embodiment of the present invention will be described in detail below.

[0027] Reference Appendix Figure 1 A cable stripping device for avoiding scratching the wire core includes a support frame 1. Multiple electric rollers 12 are slidably connected to both sides of the support frame 1. Each electric roller 12 is equipped with a drive device inside. A bidirectional lead screw 11 is rotatably connected to the front side of both ends of the support frame 1. The front ends of adjacent electric rollers 12 are threadedly connected to the outer surface of the bidirectional lead screw 11. The bidirectional lead screw 11 is used to adjust the spacing between the electric rollers 12.

[0028] When it is necessary to strip the cable, the operator can pass the cable through the inside of the electric rollers 12 and insert it into the inside of the support frame 1. By rotating the top of the bidirectional screw 11, the bidirectional screw 11 will cause the adjacent electric rollers 12 to move closer to each other, so that the outer surfaces of the electric rollers 12 will be in contact with the surface of the cable. As the electric rollers 12 rotate, they will cause the cable to move to the right, so that the inside of the support frame 1 will cut the cable sheath.

[0029] As described in the background art, during the process of stripping the cable, if the device comes into contact with a hard wire core, it is easy to scratch or even cut the internal metal conductor or optical fiber. This damage will reduce the effective cross-sectional area of ​​the metal, thereby affecting its conductivity. In severe cases, the damaged part needs to be completely removed, thereby reducing the quantity and quality of recyclable metal. Even slight scratches will lead to increased resistance and affect the current transmission efficiency.

[0030] Reference Appendix Figure 1 and Figure 3 To address the issue of damage to the inner core during cutting, this embodiment employs the following technical solution: Rotating frames 301 are rotatably connected to both sides of the middle section of the support frame 1. A cutting element 302 is slidably connected to the outer surface of the rotating frame 301 in a ring-like manner. The cutting element 302 is used for stripping the cable insulation. A second sliding frame 33 is slidably connected to the opposite ends of the rotating frame 301. A guide element 35 is slidably connected to the opposite outer surface of the cutting element 302. Multiple second connecting rods 34 are rotatably connected to the outer surface of the second sliding frame 33 in a ring-like manner. The other ends of the second connecting rods 34 are rotatably connected to the outer surface of the guide element 35. The second sliding frame 33 is used to drive the guide element 35 to slide via the second connecting rods 34. A pin 38 is engaged on the inner side of each guide element 35, and the outer surface of the pin 38 slides through the inner side of the cutting element 302. The guide element 35 is used to drive the cutting element 302 to move synchronously via the pin 38.

[0031] The outer surface of the rotating frame 301 is fixedly connected with multiple guide frames 36 in a ring shape. The ends of the guide frames 36 that are far apart from each other are inclined. The inner side of the ends of the guide frames 36 that are far apart from each other is slidably connected with a third sliding frame 37. The inner side of the third sliding frame 37 is fixedly connected to the outer surface of the pin 38. The third sliding frame 37 is used to drive the pin 38 to move. The outer surface of the cutting piece 302 that is far apart from each other is fixedly sleeved with a spring 39. The other end of the spring 39 is fixedly connected to the surface of the guide piece 35. The spring 39 is used to drive the guide piece 35 to reset and move.

[0032] When the cable is placed inside the support frame 1 for stripping, the operator can move the second sliding frame 33 to the side away from each other. At this time, the second sliding frame 33 drives the guide 35 to move downward through multiple second connecting rods 34 that are rotatably connected to its outer surface. Since the pin 38 is engaged between the guide 35 and the cutting piece 302, the downward movement of the guide 35 drives the cutting piece 302 to move synchronously through the pin 38, so that the side of the cutting piece 302 that is close to each other is inserted into the insulation layer of the cable.

[0033] As the pin 38 moves downward, it drives the third sliding frame 37 to move synchronously. The third sliding frame 37 slides along the inclined surface of the guide frame 36, causing the third sliding frame 37 to shift to the right while moving downward. This causes the outer surface of the pin 38 to gradually separate from the inner side of the cutting piece 302, but the pin 38 remains inside the guide frame 35. At this time, the movement of the cutting piece 302 in the vertical direction is no longer restricted by the guide frame 35, thus providing flexible adjustment space for subsequent cutting operations.

[0034] As the cable is fed to the right, the front end of the cutter 302 cuts through the cable insulation layer. When the cutter 302 contacts the harder inner core, the core applies reverse pressure to the cutter 302, causing it to slide upward and compress the spring 39. The compressed state of the spring 39 effectively prevents the cutter 302 from cutting further, thus avoiding damage to the inner core and ensuring that the electrical performance and mechanical strength of the cable are not affected. After the cutter 302 passes the core, the spring 39 returns to its original state, pushing the cutter 302 to reset and allowing it to cut through the cable insulation layer again.

[0035] In the initial cutting stage, the pin 38 is inserted into the inside of the cutting element 302 to ensure stable cutting into the insulation layer and prevent the cutting element 302 from retracting prematurely due to unexpected factors. During the cutting process, after the pin 38 is released from the restriction of the cutting element 302, the cutting element 302 can achieve precise cutting, further protecting the internal wire core from damage.

[0036] When the cable insulation stripping operation is completed, the worker presses the second sliding frame 33 towards one side. As the second sliding frame 33 moves, it drives the guide 35 to move upward through the second connecting rod 34. Since the outer surface of the pin 38 still slides on the inner side of the guide 35, as the guide 35 moves upward, it not only drives the cutting piece 302 to move synchronously through the spring 39, but also drives the third sliding frame 37 to move synchronously through the pin 38. When the third sliding frame 37 slides along the inclined surface of the guide frame 36, its outer surface interacts with the inclined surface of the guide frame 36, causing the third sliding frame 37 to shift to the left, thereby driving the pin 38 to re-insert into the inner side of the cutting piece 302, thus facilitating the subsequent movement of the cutting piece 302 to cut open the cable insulation layer.

[0037] Both ends of the electric roller 12, which are far apart from each other, are rotatably connected to a first connecting rod 3. A movable shaft 31 is rotatably connected between the ends of adjacent first connecting rods 3 that are close to each other. The electric roller 12 is used to drive the movable shaft 31 to move through the first connecting rods 3. The outer surface of the second sliding frame 33 is symmetrically fixedly connected to a first sliding frame 32. The first sliding frame 32 is used to drive the second sliding frame 33 to move. The side of the first sliding frame 32 that is far apart from each other is rotatably connected to the outer surface of the movable shaft 31. The movable shaft 31 is used to drive the first sliding frame 32 to move.

[0038] Before stripping the cable, the operator needs to rotate the bidirectional screw 11 to move the adjacent electric rollers 12 closer to each other. When the electric rollers 12 move, they will drive the first connecting rod 3 to move synchronously. When the first connecting rod 3 moves inward, it applies a squeezing force to the moving shaft 31, thereby driving the first sliding frame 32 to stretch and move away from each other. The movement of the first sliding frame 32 further drives the second sliding frame 33 to unfold synchronously, causing the cutting piece 302 to automatically insert into the insulation layer of the cable, improving the continuity and automation of the overall operation of the equipment.

[0039] After the cable stripping operation is completed, the operator rotates the bidirectional screw 11 in the opposite direction, causing the electric roller 12 to move back to the side away from each other. At this time, the first connecting rod 3 drives the moving shaft 31 to move to the side closer to each other, and drives the second sliding frame 33 to reset synchronously through the first sliding frame 32, so that the cutting piece 302 slides away from each other and detaches from the cable insulation layer, making it easier to carry out the next stripping operation.

[0040] When stripping the insulation of a cable, the insulation layer is cut by moving the cable longitudinally while keeping the cutting piece 302 fixed. This method can easily lead to eccentric cutting, resulting in one side being cut too deeply while the other side is not completely cut, affecting the quality of stripping. Cutting in a fixed direction will generate a force in one direction on the cable, which can easily cause the cable to twist or shift, affecting not only the cutting effect but also potentially damaging the internal structure of the cable.

[0041] Reference Appendix Figures 1-2To address the issue of eccentric cutting during cable cutting, this embodiment employs the following technical solution: A geared disc 2 is fixedly connected to the outer surface of the rotating frame 301 on one side, and the geared disc 2 drives the rotating frame 301 to rotate. A protective shell 21 is fixedly connected to the upper surface of the front side of the support frame 1. A spur gear 22 is symmetrically rotatably connected to the inner side of the protective shell 21. The outer surface of the spur gear 22 meshes with the outer surface of the geared disc 2, and the spur gear 22 drives the geared disc 2 to rotate. A first motor 25 is fixedly connected to the upper surface of the bottom of the protective shell 21, and the output shaft of the first motor 25 passes through the inner side of the protective shell 21. A first bevel gear 23 is fixedly connected to the output shaft of the first motor 25, and the first motor 25 drives the first bevel gear 23 to rotate. A second bevel gear 24 is symmetrically fixedly connected to the side of the spur gear 22 that is far apart from each other. The outer surface of the first bevel gear 23 meshes with the outer surface of the second bevel gear 24, and the first bevel gear 23 drives the spur gear 22 to rotate through the second bevel gear 24.

[0042] When the cable insulation layer is cut, the first motor 25 starts, and its output shaft drives the first bevel gear 23 to rotate. The first bevel gear 23 transmits the rotational power synchronously to the spur gears 22 on both sides through the two second bevel gears 24 meshing with it, so that the left and right spur gears 22 rotate in opposite directions, causing the left spur gear 22 to rotate clockwise and the right spur gear 22 to rotate counterclockwise.

[0043] Furthermore, the left spur gear 22 meshes with the left gear disk 2, causing the left rotating frame 301 to rotate counterclockwise, thereby driving the left cutting piece 302 to perform a counterclockwise circular cut; similarly, the right spur gear 22 meshes with the right gear disk 2, causing the right rotating frame 301 to rotate clockwise, thereby driving the right cutting piece 302 to perform a clockwise circular cut.

[0044] The cutting elements 302 on both sides make circular cuts in different directions, so that the torque generated during the cutting process cancels each other out, thereby effectively preventing the cable from twisting during processing. The cable remains stable and centered during the cutting process, improving the smoothness and controllability of the cutting process. In addition, the cutting elements 302 act on the insulation layer from different directions at the same time, making the cutting force more evenly distributed on the circumference of the cable, avoiding local overcutting or eccentric cutting caused by excessive force on one side, thus achieving a more uniform and stable cutting effect.

[0045] As the rotating frame 301 continues to cut the insulation layer of the cable, the cut waste will fall into the receiving part 13 for collection. As the cable is continuously cut, the waste will continue to accumulate at the bottom of the equipment, making the equipment susceptible to interference and affecting its operation.

[0046] Reference Appendix Figures 4-5To address the problem of continuous waste accumulation inside the receiving component 13, this embodiment employs the following technical solution: Reciprocating screws 45 are rotatably connected to the sides of the receiving components 13 that are close to each other. Push plates 46 are threadedly connected to the outer surfaces of the front ends of the reciprocating screws 45. The lower surface of the other end of the push plate 46 is slidably connected to the upper surface of the receiving component 13. The reciprocating screws 45 drive the push plates 46 to slide back and forth, and the push plates 46 are used to compress the waste. A second motor 43 is fixedly connected to the front end of the left receiving component 13. The output shaft of the second motor 43 is fixedly connected to the front end of the left reciprocating screw 45. A belt 44 is driven to the outer surface of the output shaft of the second motor 43. The other end of the belt 44 is driven to the front end of the right reciprocating screw 45. The second motor 43 drives the reciprocating screws 45 on both sides to rotate synchronously. The inner diameter of the rotating frame 301 gradually increases on the sides that are far apart from each other, and the inner wall of the rotating frame 301 is used to guide the waste.

[0047] When the cutting piece 302 makes a ring cut on the insulation layer of the outer surface of the cable, the cut waste material falls into the rotating frame 301. Since the inner diameter of the rotating frame 301 gradually increases from the center to both sides, the waste material is guided to both sides and falls into the receiving part 13 by the combined action of centrifugal force and guide surface during the rotation of the rotating frame 301. As the waste material continues to accumulate inside the receiving part 13, the output shaft of the second motor 43 will drive the reciprocating screw 45 on the left side to rotate. When the output shaft of the second motor 43 rotates, it will drive the reciprocating screw 45 on the right side to rotate synchronously through the belt 44. When the reciprocating screws 45 on both sides rotate synchronously, the reciprocating screws 45 can drive the push plate 46 to move back and forth along the upper surface of the receiving part 13, so that the push plate 46 can push the waste material inside the receiving part 13 backward, effectively preventing the accumulation of waste material from affecting the normal operation of the equipment.

[0048] The front side of each receiving component 13 is rotatably connected to a rotating shaft 4. A shielding cloth 41 is fixedly wound around the outer surface of each rotating shaft 4. The rear end of the shielding cloth 41 passes through the front side of the receiving component 13 and is fixedly connected to the upper surface of the push plate 46. The push plate 46 is used to drive the shielding cloth 41 to unfold. The shielding cloth 41 is used to shield the waste material. Torsion springs 42 are fixedly connected to both sides of the rotating shaft 4. The ends of the torsion springs 42 that are far apart from each other are fixedly connected to the inner side of the front end of the receiving component 13. The torsion springs 42 are used to drive the shielding cloth 41 to reset and rewind through the rotating shaft 4.

[0049] When the push plate 46 moves backward, it pulls the rear end of the shielding cloth 41, causing it to unfold and cover the upper surface of the receiving part 13. During this process, the stretching of the shielding cloth 41 causes the rotating shaft 4 to rotate, which drives the torsion spring 42 to undergo elastic deformation and store force. The unfolded shielding cloth 41 can effectively shield the upper surface of the receiving part 13 and receive the waste material falling from the inside of the rotating frame 301.

[0050] When the reciprocating screw 45 continues to rotate, causing the push plate 46 to move forward to reset, the rear end of the shielding cloth 41 moves forward synchronously with the push plate 46. At this time, the torsion spring 42, which is in a stored state, will roll up the shielding cloth 41 through the rotating shaft 4. During this process, the shielding cloth 41 slides past the front side of the receiving part 13, and the waste material remaining on its upper surface is brought into the receiving part 13 to complete the recycling of waste material and prevent the waste material from scattering during the movement of the push plate 46.
