Description

Technical Field

[0001] This invention belongs to the field of wire stripping technology, specifically a wire stripping machine suitable for wires of different thicknesses. Background Technology

[0002] Electrical wires consist of a conductive core made of metal and an insulating sheath that surrounds the conductive core. During electrical construction or waste recycling, it is necessary to strip the insulation sheath from the wires. Currently, this is sometimes done by stripping a section of the wire, and sometimes by stripping the insulation sheath from the entire wire.

[0003] A patent with publication number CN113695763B discloses a wire stripping machine suitable for wires of different thicknesses. This patent uses two sets of clamping blocks to clamp the outer surface of the wire end. Then, an electric telescopic device drives a universal ball bearing and rollers to move synchronously towards one side of the wire until six sets of rollers wrap around the outer circumference of the wire, achieving "wrapping and limiting" of the wire. An electric track drives an electric slider to slide on its upper surface. Under the action of the blades, the blades automatically cut the insulation layer. There are two sets of blades, cutting synchronously from top to bottom, dividing the insulation layer in two. Subsequently, the output end of an electric push cylinder drives a toothed plate forward, which meshes with and drives a driven gear to rotate. The upper and lower sets of blades rotate 90 degrees respectively, and in opposite directions. The drive motor inside the drive unit drives the connecting frame, ring sleeve, and blade components to rotate clockwise. The upper and lower sets of blades perform circumferential cutting of the insulation layer's cutting end, allowing the halved insulation layer to quickly detach from the exposed wire core, eliminating the hassle of manual tearing.

[0004] The above-mentioned solution still has some problems in practical application. Usually, one end of the wire is inserted into the wire stripping machine, and the gears inside the machine rotate to move the wire. During the movement of the wire, the stripping machine uses a cutting blade to cut a slit along the outer sheath of the wire. Then, the worker separates the cut wire sheath from the wire core from one end of the wire, pulling the wire core with one hand and the outer sheath with the other to strip the wire. However, when stripping long wires, the stripping machine needs to cut the entire wire first, and then the worker has to tear the wire sheath from the wire core to strip the entire wire. This is not only cumbersome, but the wire sheath and the wire core are also stuck together, making it very difficult for the operator to separate the wire sheath from the wire core later, which is not conducive to effectively improving the efficiency of wire stripping.

[0005] Therefore, the present invention provides a stripping machine suitable for wires of different thicknesses. Summary of the Invention

[0020] The beneficial effects of this invention are as follows:

[0021] 1. The present invention discloses a wire stripping machine suitable for wires of different thicknesses. By driving a cutting adjustment component to expand and adjust the position of the cutting blade, a fastening bolt locks the crank handle and the first slider. Simultaneously, a rotating cylinder is driven to transport and move the wire, thereby using the cutting blade to cut an opening in the wire's outer sheath. The cutting of the wire's outer sheath involves two symmetrical openings. Combined with the pressure from the rotating cylinder, the cut outer sheath is loosened and removed, making it easier for workers to peel off the wire's outer sheath later. This improves the efficiency of wire core recovery and solves the problem of existing wire stripping machines, which, when stripping wires of different diameters, require multiple cuts and stripping operations to remove the wire core due to the inconvenience of adjusting the cutting blade length. Conversely, when cutting thinner wires, if the cutting blade length exceeds the thickness of the outer sheath, it may cut the wire core, causing damage to both the core and the cutting blade.

[0022] 2. The present invention provides a wire stripping machine suitable for wires of different thicknesses. By driving the stripping assembly to move the semi-circular stripping frames closer together, it can be adjusted according to the wire core to be stripped, so that the wire core can slide between the semi-circular stripping frames. One end of the sliding rod is triangular, which can easily cut into the pre-cut opening in the wire to strip the wire. The outer side of the semi-circular stripping frame is also triangular, which can easily cut between the wire core and the outer sheath. After the rotating cylinder squeezes and conveys the stripped wire into the semi-circular stripping frame, the wire is automatically stripped. This solves the problem that existing wire stripping machines usually require the stripping machine to cut a slit along the wire, and then the worker to peel the outer sheath from the wire core from one end of the wire while pulling the wire core with one hand and the outer sheath with the other. This is not only cumbersome to operate, but also cannot effectively improve the stripping efficiency. Attached Figure Description

[0040] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments. Example

[0041] like Figures 1 to 10 As shown in the figure, a stripping machine suitable for wires of different thicknesses according to an embodiment of the present invention includes a base 1, a fixing frame 2 installed on the upper end surface of the base 1, and a transmission component 4 disposed inside the upper end surface of the fixing frame 2.

[0042] The transmission assembly 4 includes two sets of bidirectional threaded rods 47 rotatably connected in the inner cavity of the fixed frame 2, and the two bidirectional threaded rods 47 are a set, symmetrically arranged in the inner cavity of the fixed frame 2. Each set of bidirectional threaded rods 47 is externally threaded to two first sliders 5, and a conveying and stripping assembly 6 is provided between the first sliders 5 for adjusting the spacing between the conveying and stripping assemblies 6 according to the diameter of the wire to be cut.

[0043] The conveying and uncoating assembly 6 includes four rotating cylinders 61 rotatably connected between the first slider 5, with two rotating cylinders 61 forming a group and the two groups of rotating cylinders 61 arranged symmetrically to each other for extruding and conveying the wires. A cutting and adjusting assembly 7 is provided between every two rotating cylinders 61.

[0044] Furthermore, the cutting adjustment assembly 7 includes a fixed cylinder 71 disposed between the rotating cylinders 61, and two cutting blades 76 are disposed on the outside of the fixed cylinder 71 for cutting and stripping the wires.

[0045] Specifically, in existing technology, one end of the wire is usually inserted into the wire stripping machine, and the gears inside the machine rotate to move the wire. During the movement of the wire, the stripping machine uses a cutting blade to cut a slit along the outer sheath of the wire. Then, the worker separates the cut wire sheath from the wire core from one end of the wire, pulling the wire core with one hand and the outer sheath with the other to strip the wire. However, the current method of stripping is not only cumbersome to operate, but the wire sheath and the wire core are also stuck together, making it very difficult for the operator to peel off the wire sheath and the wire core later, which makes it difficult to effectively improve the stripping efficiency of the wire.

[0046] This invention solves the aforementioned problems by placing the wire between two sets of rotating cylinders 61 and simultaneously driving the bidirectional threaded rod 47 to rotate. This causes the first slider 5, driven by the threaded rod 47, to move closer together, which in turn causes the rotating cylinders 61 to move closer together. This allows for adjustment of the spacing according to different wire thicknesses and clamping and fixing the wire. Simultaneously, the rotating cylinders 61 rotate, driving the cutting blade 76 to slide out of the rotating cylinders 61. During rotation, the rotating cylinders 61 compress and transport the wire, while the cutting blade 76 cuts and removes the insulation. After making two symmetrical cuts on the wire, the cutting blade 76, using the compressive force of the rotating cylinders 61 to transport the wire, further compresses and opens the cut wire insulation, facilitating subsequent stripping operations and improving the convenience of wire core recovery.

[0047] like Figure 1 , Figure 3 and Figure 9 As shown, a rotating groove 20 is provided inside the upper end of the fixed frame 2. A rotating shaft 46 is rotatably connected to the inner cavity of the rotating groove 20. Three driven bevel gears 44 are evenly fixed to the outside of the rotating shaft 46. One end of the bidirectional threaded rod 47 passes through the fixed frame 2 and is fixed to an auxiliary bevel gear 45 located in the inner cavity of the rotating groove 20. The auxiliary bevel gear 45 is meshed with the driven bevel gear 44.

[0048] like Figure 1 , Figure 3 and Figure 9 As shown, a cylinder 48 is rotatably connected to the inner cavity of the rotating groove 20. Three transmission bevel gears 43 are rotatably connected to the outside of the cylinder 48. Two transmission bevel gears 43 located at both ends of the cylinder 48 are meshed with driven bevel gears 44. A knob 41 is rotatably connected to the upper end of the fixed frame 2. A drive bevel gear 42 is fixedly connected to one end of the knob 41 located in the inner cavity of the rotating groove 20. The drive bevel gear 42 is meshed with the transmission bevel gear 43.

[0049] Specifically, during the stripping of the wires, the drive knob 41 is rotated, which in turn drives the bevel gear 42 to rotate, which in turn engages with the transmission bevel gear 43 to rotate, causing the cylinder 48 to rotate. The cylinder 48, in turn, drives the transmission bevel gear 43 to rotate, which in turn engages with the driven bevel gear 44 to rotate. Simultaneously, the driven bevel gear 44 drives the rotating shaft 46 to rotate, which in turn drives the driven bevel gear 44 to engage with the auxiliary bevel gear 45 to rotate, which in turn drives the bidirectional threaded rod 47 to rotate. At the same time, the threaded first slider 5 moves closer to each other, and the first slider 5 also drives the rotating cylinder 61 to move closer to each other. This allows the spacing of the rotating cylinders 61 to be adjusted according to the different thicknesses of the wires, and the wires to be clamped and fixed, improving the stability of the wire transport.

[0050] like Figures 3 to 6 and Figure 10 As shown, two first rotating columns 17 and two second rotating columns 18 are rotatably connected between the first sliders 5, and each second rotating column 18 is fixedly connected to the fixed cylinder 71. The two first rotating columns 17 and the two second rotating columns 18 are symmetrically arranged. The interior of the first rotating column 17 is hollow. The four rotating cylinders 61 are rotatably connected to the exterior of the two first rotating columns 17 and the two second rotating columns 18, respectively.

[0051] like Figures 3 to 6 and Figure 10 As shown, the first rotating column 17 and the second rotating column 18 are both fixedly connected to multiple fixed blocks 64 outside the inner cavity of the rotating cylinder 61. One end of each fixed block 64 is rotatably connected to a push rod 65. One end of the push rod 65 is rotatably connected to a connecting column 62. Both ends of the connecting column 62 are fixedly connected to sliding plates 63. The sliding plates 63 are slidably connected to the inner wall of the rotating cylinder 61. The outside of the sliding plates 63 is provided with an anti-slip rubber layer for pressing the wire conveying and opening the cut wire shell.

[0052] Specifically, when extruding and opening the outer sheath of wires of different thicknesses, the first rotating column 17 and the second rotating column 18 are rotated, causing the first rotating column 17 and the second rotating column 18 to drive the fixed block 64 to rotate. At the same time, the fixed block 64 drives the push rod 65 to rotate, which in turn causes the push rod 65 to pull the connecting column 62 to move, thereby causing the sliding plate 63 to slide inside the rotating cylinder 61. The length of the sliding plate 63 outside the rotating cylinder 61 is adjusted. After the position of the sliding plate 63 sliding out of the rotating cylinder 61 is adjusted, the first rotating column 17 and the second rotating column 18 are inserted and fixed to the rotating cylinder 61. Then, the rotating cylinder 61 is driven to move closer to each other, extruding and fixing the wire. At the same time, the rotating cylinder 61 is driven to move closer to each other. 1. Rotation drives the wire to be transported, thereby squeezing the cut outer sheath and loosening the wire core. This makes it easier for operators to peel off the outer sheath of the wire core later, improving the efficiency of wire core recycling. This solves the problem that existing wire stripping machines suitable for different wire thicknesses usually use gears to clamp the wire for transport. During the transport process, a cutting blade makes a cut on the outside of the wire, and then workers peel off the outer sheath and recycle the wire core. However, since only one cut is made on the wire, and the outer sheath is still stuck to the wire core, it takes a long time to separate the outer sheath from the wire core, which is not only time-consuming and labor-intensive, but also affects the efficiency of wire core recycling.

[0053] like Figure 1 , Figure 5 and Figure 7As shown, a crank handle 72 is rotatably connected to the inner cavity of the fixed cylinder 71. A rotating frame 73 is fixedly connected to the outside of the inner cavity of the fixed cylinder 71. A pull rod 74 is rotatably connected to the outside of the rotating frame 73. An adjusting rod 75 is rotatably connected to one end of the pull rod 74. The adjusting rod 75 is slidably connected to the inner wall of the fixed cylinder 71. One end of the adjusting rod 75 is fixedly installed to the cutting blade 76. The crank handle 72 can be inserted into and locked to the first slider 5.

[0054] Specifically, when stripping the outer sheath of wires of different diameters, the crank handle 72 is turned, causing the rotating frame 73 to rotate. The rotating frame 73 and the pull rod 74 are electrically controlled for intelligent rotation. Simultaneously, the pull rod 74 pulls the adjusting rod 75 to move. When the adjusting rod 75 is adjusted to a certain position, the rotating frame 73 and the pull rod 74 are locked at that angle by system control, similar to a robotic arm automatically fixing itself at that position after rotating to a certain angle. This prevents the adjusting rod 75 from being subjected to the reverse force of the wire sheath. The adjusting rod 75 will then rotate towards the rotating frame 73 along with the pull rod 74. The adjusting rod 75 then slides inside the fixed cylinder 71, causing the cutting blade 76 to expand. Then, the crank handle 72 is locked to the first slider 5 using a fastening bolt, simultaneously driving the rotating cylinder 61 to transport the wire. The cutting blade 76 makes symmetrical cuts to the outer sheath of the wire. Combined with the pressure from the rotating cylinder 61, this loosens and removes the outer sheath, making it easier for workers to peel it off later. This improves the efficiency of wire core recovery and solves the problem of existing wire stripping machines, which are suitable for different wire thicknesses, having difficulty adjusting the cutting blade length. This results in multiple cuts and stripping operations for thicker wires to extract the core, while for thinner wires, the blade length exceeds the sheath thickness, causing damage to both the core and the cutting blade. Example

[0055] like Figure 1 , Figure 3 and Figure 4 As shown, a driven pulley 19 is fixedly connected to the outside of one end of the rotating cylinder 61 and the first slider 5. A belt 15 is externally connected to the driven pulley 19. A drive pulley 13 is internally connected to one end of the belt 15. A wire straightening assembly is rotatably connected between the drive pulleys 13 for straightening and conveying the wire.

[0056] like Figure 1 , Figure 3 and Figure 4As shown, the wire straightening assembly includes two limiting slide pins 9 fixed in the inner cavity of the fixing frame 2, and four second sliders 10 are symmetrically slidably connected to the outside of the two limiting slide pins 9, with two sliders sliding outside the limiting slide pins 9 in groups. A spring 16 is fixedly connected to one end of each second slider 10, and one end of the spring 16 is fixedly connected to the inner wall of the fixing frame 2 and the base 1. A fixing plate 8 is fixedly connected between the second sliders 10, and two transmission rollers 11 are rotatably connected between every two fixing plates 8. The transmission rollers 11 are I-shaped and are externally connected to a conveyor belt 12. The conveyor belt 12 is provided with a rubber toothed rack to increase the friction with the wire. One end of the transmission roller 11 passes through the fixing plate 8 and is fixedly connected to the transmission pulley 13. A servo motor 14 is installed at one end of the fixing plate 8, and the output shaft end of the servo motor 14 is fixedly connected to the transmission roller 11.

[0057] Specifically, during the stripping of the wire, one end of the wire is inserted between the conveyor belts 12, and the wire pushes the conveyor belts 12 away from each other, causing the conveyor belts 12 to drive the transmission rollers 11 to move synchronously. This causes the fixing plates 8 to move away from each other, which in turn causes the fixing plates 8 to drive the second slider 10 to slide outside the limiting slide post 9, compressing the spring 16 and moving it away from each other. Then, the rebound force of the spring 16 pushes the second slider 10 closer together, causing the fixing plates 8 and the transmission rollers 11 to move synchronously. At the same time, the conveyor belts 12 clamp and fix the wire. The conveyor belts 12 are uniformly provided with rubber toothed strips on the outside to increase the friction with the wire and ensure the stability of the wire conveying. Then, the servo motor 14 is started to drive the transmission rollers 11 to rotate, and the transmission rollers 11 drive the conveyor belts 12 to rotate, thus causing the conveyor belts 12 to transport the wire. The transmission rollers 11 are I-shaped, thus transporting the wire. During the wire movement, after the wire passes between the conveyor belts 12, the wire is straightened to prevent bending from affecting the cutting position. It also prevents bent wires from deviating during transport and failing to pass under the cutting blade 76, thus preventing the wire from being cut. Furthermore, as the transmission roller 11 rotates, it drives the transmission pulley 13 to rotate, which in turn drives the transmission belt 15 to rotate, and simultaneously drives the driven pulley 19 to rotate, thereby driving the conveyor stripping assembly 6 to cut and strip the wire. This solves the problem that existing wire stripping machines suitable for different wire thicknesses cannot accurately strip the outer sheath if the wire is not straightened during transport. The twisted or messy state of the wire prevents the wire stripping machine from doing so accurately, and the blades or rollers of the wire stripping machine cannot fully adhere to the outer sheath, resulting in uneven stripping or insufficient stripping depth, which affects the stripping effect and, in severe cases, damages the wire core.

[0058] like Figure 1 , Figure 8 and Figure 10As shown, a molting assembly 3 is installed on one side of the fixing frame 2, and the molting assembly 3 includes a mounting frame 31 installed on one side of the fixing frame 2. Two first drive shafts 35 are rotatably connected inside the upper and lower ends of the mounting frame 31. A second bevel gear 37 is fixedly connected to both ends of the first drive shaft 35. The second bevel gear 37 is meshed with a third bevel gear 38. A second drive shaft 39 is fixedly connected between the third bevel gears 38.

[0059] like Figure 1 , Figure 8 and Figure 10 As shown, a connecting bevel gear 33 is fixedly connected to the outside of the first drive shaft 35. The connecting bevel gear 33 is meshed with a first bevel gear 34. A threaded rod 36 is fixedly connected to one end of the first bevel gear 34. A sliding rod 310 is threadedly connected to the outside of the threaded rod 36. One end face of the sliding rod 310 is triangular. The sliding rod 310 is slidably connected to the mounting bracket 31. A semi-circular stripping frame 311 is fixedly connected to one end of the sliding rod 310. The semi-circular stripping frame 311 is triangular in shape and is used to slide between the wire core and the outer sheath for stripping work. A T-shaped bevel gear 32 is rotatably connected to the upper end of the mounting bracket 31. The T-shaped bevel gear 32 is meshed with the connecting bevel gear 33.

[0060] Specifically, after the cut wire is exfoliated by squeezing it with the rotating cylinder 61, the T-shaped bevel gear 32 is rotated, which in turn engages with the connecting bevel gear 33, causing the first drive shaft 35 to rotate. Simultaneously, the first drive shaft 35 drives the second bevel gear 37, which in turn engages with the third bevel gear 38. During its rotation, the third bevel gear 38 drives the second drive shaft 39, which in turn engages with the second bevel gear 37, causing the first drive shaft 35 to rotate. This, in turn, drives the connecting bevel gear 33, which in turn drives the first bevel gear 34, which in turn drives the threaded rod 36. Simultaneously, the threaded rod 36 and the threaded drive slide bar 310 slide close to each other inside the mounting bracket 31, causing the slide bar 310 to... The semi-circular stripping frame 311 moves synchronously, allowing adjustment according to the wire core to be stripped, so that the wire core can slide between the semi-circular stripping frames 311. One end face of the slide rod 310 is triangular, which can easily cut into the pre-cut opening in the wire to strip the insulation. The outer side of the semi-circular stripping frame 311 is also triangular, which can easily cut between the wire core and the outer sheath, thus achieving automatic stripping of the wire. This solves the problem that existing stripping machines suitable for wires of different thicknesses usually require the stripping machine to cut a slit along the wire, and then the worker to peel the outer sheath from one end of the wire while pulling the wire core with one hand and the outer sheath with the other. This is not only cumbersome to operate, but also cannot effectively improve the stripping efficiency of wires.

[0061] Working principle: When stripping wires, the drive knob 41 is rotated, which in turn drives the bevel gear 42 to rotate, which in turn meshes with the transmission bevel gear 43 to rotate, causing the cylinder 48 to rotate. During the rotation of the cylinder 48, the transmission bevel gear 43 is driven to rotate, which in turn meshes with the driven bevel gear 44 to rotate. At the same time, the driven bevel gear 44 drives the rotating shaft 46 to rotate, and during the rotation of the rotating shaft 46, the driven bevel gear 44 meshes with the auxiliary bevel gear 45 to rotate, which in turn drives the bidirectional threaded rod 47 to rotate. Simultaneously, the threaded first slider 5 moves closer to each other, and the first slider 5 drives the rotating cylinder 61 to move closer to each other. This allows the spacing of the rotating cylinder 61 to be adjusted according to the different thicknesses of the wires, and the wires to be clamped and fixed.

[0062] When extruding and opening the outer sheath of wires of different thicknesses, the first rotating column 17 and the second rotating column 18 are rotated, causing the first rotating column 17 and the second rotating column 18 to drive the fixed block 64 to rotate. At the same time, the fixed block 64 drives the push rod 65 to rotate, which in turn causes the push rod 65 to pull the connecting column 62 to move, thereby causing the slide plate 63 to slide inside the rotating cylinder 61. The length of the slide plate 63 outside the rotating cylinder 61 is adjusted. After the position of the slide plate 63 sliding out of the rotating cylinder 61 is adjusted, the first rotating column 17 and the second rotating column 18 are inserted and fixed to the rotating cylinder 61. Then, the rotating cylinder 61 is driven to move closer to each other and extrude and fix the wire. At the same time, the rotating cylinder 61 is driven to rotate, thereby driving the wire to be transported. This allows the outer sheath of the cut wire to be extruded and the wire core to be loosened, so that the operators can more easily peel off the outer sheath of the wire core later, improving the efficiency of wire core recycling.

[0063] When stripping the outer sheath of wires of different diameters, the crank handle 72 is turned, which drives the rotating frame 73 to rotate, and then pulls the pull rod 74 to rotate. At the same time, the pull rod 74 pulls the adjusting rod 75 to move, and then the adjusting rod 75 slides inside the fixed cylinder 71. This causes the adjusting rod 75 to drive the cutting blade 76 to expand and move. Then, the crank handle 72 is locked to the first slider 5 by the fastening bolt. At the same time, the rotating cylinder 61 is driven to drive the wire to move and thus the cutting blade 76 cuts an opening in the outer sheath of the wire. When cutting the outer sheath of the wire, two openings are made symmetrically. With the help of the rotating cylinder 61 squeezing the wire, the outer sheath of the wire can be loosened and removed, so that the workers can more easily peel off the outer sheath of the wire later, which improves the recycling efficiency of the wire core.

[0064] After the cut wire is de-insulated by squeezing it with the rotating cylinder 61, the T-shaped bevel gear 32 is rotated, which in turn engages with the connecting bevel gear 33, causing the first drive shaft 35 to rotate. Simultaneously, the first drive shaft 35 drives the second bevel gear 37, which in turn engages with the third bevel gear 38. During its rotation, the third bevel gear 38 drives the second drive shaft 39, which in turn engages with the second bevel gear 37, causing the first drive shaft 35 to rotate. This, in turn, drives the connecting bevel gear 33, which in turn drives the first bevel gear 34, causing the first... The bevel gear 34 drives the threaded rod 36 to rotate, while the threaded rod 36 and the threaded transmission slide rod 310 slide close to each other inside the mounting bracket 31. This causes the slide rod 310 to drive the semi-circular stripping frame 311 to move synchronously. This allows for adjustment according to the wire core to be stripped, so that the wire core can slide between the semi-circular stripping frames 311. One end face of the slide rod 310 is triangular, which can easily cut into the cut of the wire to strip the wire. The outer side of the semi-circular stripping frame 311 is triangular, which can easily cut between the wire core and the outer sheath, thus realizing automatic stripping of the wire.
