Description

Technical Field

[0001] This invention relates to the field of electrical engineering technology, and more specifically to a wire stripping device. Background Technology

[0002] In electrical engineering, wire stripping equipment is a specialized tool or machine used to remove the outer insulation (plastic, rubber, Teflon, etc.) of wires / cables to expose the copper / aluminum core. The core requirement is to remove the insulation cleanly without damaging the wire core. However, existing wire stripping equipment suffers from several drawbacks: First, the blades wear out quickly and have a short lifespan. Ordinary carbon steel blades are prone to dulling when cutting copper and aluminum wires, while carbide blades are prone to chipping, requiring frequent blade replacements and resulting in high maintenance costs. Second, there is a lack of precise grinding adjustment mechanisms. Excessive grinding time further reduces blade lifespan, while insufficient grinding time fails to achieve the required sharpness, affecting the stripping effect. Third, the coordination between cable transport, cutting, and grinding during the stripping process is poor. The grinding intensity cannot be adaptively adjusted according to the cable cutting length, leading to low stripping efficiency and inconsistent results, making it difficult to meet the needs of large-scale and precise electrical engineering construction. Summary of the Invention

[0003] The present invention aims to at least partially solve one of the technical problems in the related art.

[0018] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0019] The wire stripping device 100 of the present invention will now be described in detail with reference to the accompanying drawings.

[0020] like Figures 1 to 7As shown, the wire stripping device 100 of this embodiment includes a frame 1, a conveying assembly 2, a cutting and polishing assembly 4, a timing assembly 3, and an adjusting assembly 5. The conveying assembly 2 is mounted on the frame 1 and has a conveying position for conveying cables. The cutting and polishing assembly 4 includes a cutting blade 49 and a polishing stone 414. The polishing stone 414 is mounted on the frame 1, and the cutting blade 49 moves along a first direction (e.g., ...). Figure 1 The cutting blade 49 is movably positioned (vertically) and has a cutting position and a grinding position. In the cutting position, the cutting blade 49 cuts the cable located on the conveying position. In the grinding position, the cutting blade 49 abuts against the grinding stone 414. The timing component 3 is used to count the duration of the cutting blade 49 in the cutting position. The adjusting component 5 is electrically connected to the timing component 3 to receive timing information from the timing component 3, and the adjusting component 5 is connected to the cutting and grinding component 4 to adjust the duration of the cutting blade 49 in the grinding position.

[0021] In use, the cable is placed in the conveying position, and the conveying component 2 conveys the cable. The cutting and grinding component 4 moves the cutting blade 49 to the cutting position, where it cuts the cable insulation. The timing component 3 records the duration the cutting blade 49 remains in the cutting position to obtain the length of the cut cable. By coordinating the adjustment component 5 and the timing component 3, the time the cutting blade 49 remains in the grinding position can be adjusted according to the cable cutting length, thus adjusting the grinding intensity of the cutting blade 49. This avoids excessive wear due to excessive grinding time or insufficient sharpness due to insufficient grinding time, effectively alleviating the dulling of ordinary carbon steel cutting blades 49 and the chipping of carbide cutting blades 49, reducing the frequency of cutting blade replacement and lowering maintenance costs.

[0022] To make the scheme of this application easier to understand, an example will be given, in which the first direction is the same as the up-down direction and the second direction is the same as the front-back direction. The up-down direction is as follows: Figures 1 to 3 As shown, the front and back directions are as follows Figures 1 to 3 As shown.

[0023] The wire stripping device 100 of this invention includes a frame 1, a conveying component 2, a cutting and polishing component 4, a timing component 3, and an adjustment component 5.

[0024] The rack 1 includes a chassis 11 and a mounting frame 12. The chassis 11 is located at the lower end of the mounting frame 12 and the chassis 11 is fixedly connected to the mounting frame 12.

[0025] The conveying assembly 2 is mounted on the mounting frame 12 of the frame 1. The conveying assembly 2 has a conveying position for conveying cables. The conveying assembly 2 includes a first motor 23, a first conveying roller 21, and a first guide wheel 24. The first motor 23 is mounted on the mounting frame 12 of the frame 1. The first conveying roller 21 is rotatably mounted on the mounting frame 12 of the frame 1. There are at least three first conveying rollers 21. Multiple first conveying rollers 21 are arranged at intervals along the second direction. One of the first conveying rollers 21 is drivenly connected to the first motor 23. Multiple first conveying rollers 21 are drivenly connected. The first conveying roller 21 is provided with a first guide wheel 24. Two adjacent first guide wheels 24 form a conveying position. The second direction is perpendicular to the first direction.

[0026] When the first motor 23 is started, its output end will drive a first conveying roller 21 fixedly connected to it to rotate synchronously. This first conveying roller 21 drives another first conveying roller 21 to rotate synchronously in the same direction. Multiple first conveying rollers 21 rotate synchronously, and multiple conveying positions rotate synchronously, which can stably receive cables and achieve uniform speed conveying, providing a stable feeding basis for cable cutting.

[0027] Specifically, there are three first conveying rollers 21, and one end of each of the three first conveying rollers 21 is fixedly connected to a first gear 22. A gear belt is provided on the outer side of the three first gears 22. A first motor 23 is fixedly connected to one side of the mounting frame 12, and the output end of the first motor 23 is fixedly connected to one end of one of the first conveying rollers 21.

[0028] The cutting and polishing assembly 4 includes a cutting blade 49 and a polishing stone 414. The polishing stone 414 is mounted on the mounting bracket 12 of the frame 1. The cutting blade 49 is positioned along a first direction (e.g., ...). Figure 1 The cutting blade 49 is movably set in the vertical direction and has a cutting position and a grinding position. In the cutting position, the cutting blade 49 cuts the cable located on the conveying position, and in the grinding position, the cutting blade 49 abuts against the grinding stone 414.

[0029] The cutting and grinding assembly 4 includes a telescopic component 41, a lifting plate 42, a second motor 411, and a rotating shaft 48. The telescopic component 41 is mounted on the frame 1, and its telescopic end is connected to the lifting plate 42. The lifting plate 42 has a through hole through which a grinding stone 414 passes. The second motor 411 is mounted on the lifting plate 42, and the rotating shaft 48 is rotatably mounted on the lifting plate 42. A cutting blade 49 is mounted on the rotating shaft 48. The second motor 411 is connected to the rotating shaft 48 in a transmission connection. In use, when the cable is conveyed to the conveying position, the second motor 411 is turned on, causing the rotating shaft 411 to rotate, thereby rotating the cutting blade 49. At the same time, the telescopic component 41 is activated, pushing the lifting plate 42 downward, which in turn moves the cutting blade 49 downward to the cutting position, where the cutting blade 49 cuts the cable insulation.

[0030] When the cutting blade 49 needs to be sharpened, the telescopic component 41 drives the lifting plate 42 to rise, thereby moving the cutting blade 49 upward to the sharpening position. The rotating cutting blade 49 is sharpened on the polishing stone 414 to repair the dull parts of the cutting blade 49 and to completely remove the insulation residue on the cutting blade, thus improving the wire stripping quality.

[0031] Specifically, the telescopic component 41 uses a cylinder.

[0032] Specifically, the cutting and grinding assembly 4 includes a fixed plate 47, which is mounted on the lifting plate 42. The rotating shaft 48 is rotatably mounted on the fixed plate 47. A fourth gear 410 is mounted on the fixed plate 47, and a fifth gear 412 is mounted on the output end of the second motor 411. The fourth gear 410 and the fifth gear 412 mesh and drive each other, thereby enabling the second motor 411 to drive the rotation of the cutting blade 49 on the rotating shaft 48.

[0033] The cutting and grinding assembly 4 further includes a connecting plate 45, a second conveying roller 46, and a second guide wheel 413. One end (upper end) of the connecting plate 45 is connected to the lifting plate 42, and the other end (lower end) of the connecting plate 45 is rotatably provided with the second conveying roller 46. The second guide wheel 413 is provided on the second conveying roller 46, and the second guide wheel 413 is opposite to the first guide wheel 24 in a first direction. When the telescopic member 41 drives the lifting plate 42 to move downward, it drives the second conveying roller 46 and the second guide wheel 413 to move downward. The second guide wheel 413 and the first guide wheel 24 cooperate to squeeze the cable located at the conveying position, pressing the cable tightly. While realizing the forward movement of the conveyed cable, it can enhance the stability of the cable conveying, avoid the cable from deviating or slipping during the conveying process, and reduce the stripping deviation caused by unstable conveying.

[0034] In some embodiments, the cutting and grinding assembly 4 further includes a first connecting rod 43 and a second elastic member 44. The first connecting rod 43 is slidably disposed on the lifting plate 42 and is connected to one end of the connecting plate 45. The second elastic member 44 is disposed between one end of the connecting plate 45 and the lifting plate 42. When the second guide wheel 413 cooperates with the first guide wheel 24 to compress the cable, the second elastic member 44 is in a compressed state. Utilizing its elastic force, it can flexibly compress the cable, avoiding excessive pressure that could damage the cable core. Simultaneously, it can adapt to cables of different diameters, ensuring a proper compression effect.

[0035] Therefore, the flexible clamping of the second elastic element 44 allows the first guide wheel 24 and the second guide wheel 413 to be compatible with various cable specifications, making them highly versatile and effectively protecting the wire core from being squeezed and damaged. At the same time, the second guide wheel 413 can rotate synchronously with the cable, reducing friction during cable transport, avoiding wear on the cable surface, and ensuring the integrity of the cable after stripping.

[0036] Specifically, the second elastic element 44 is a second spring, which is sleeved on the first connecting rod 43.

[0037] The timing component 3 is used to count the duration that the cutting blade 49 is in the cutting position.

[0038] The timing component 3 includes a first take-up roller 33, a second take-up roller 310, a take-up belt 311, and a sensor. The first take-up roller 33 is coaxially arranged with the first conveyor roller 21. The second take-up roller 310 is rotatably mounted on the frame 1. The second take-up roller 310 and the first take-up roller 33 are connected by a drive. One end of the take-up belt 311 is mounted on the first take-up roller 33, and the other end of the take-up belt 311 is mounted on the second take-up roller 310. The sensor abuts against the take-up belt 311 on the second take-up roller 310. The sensor is connected to the adjustment component 5.

[0039] Specifically, the second take-up reel 310 is coaxially provided with a second gear 31, and the first take-up reel 33 is coaxially provided with a third gear 32. The third gear 32 meshes with the second gear 31, and the rotation directions of the third gear 32 and the second gear 31 are opposite. The rotation directions of the first take-up reel 33 and the second take-up reel 310 are also opposite.

[0040] In operation, when the conveying assembly 2 is working, the rotation of the first conveying roller 21 drives the first take-up roller 33 to rotate. The first take-up roller 33, through the meshing of the second gear 31 and the third gear 32, drives the second take-up roller 310 to rotate. During the rotation of the two take-up rollers, the take-up belt 311 is unwound and wound accordingly. The winding length of the take-up belt 311 is proportional to the cable conveying length. Thus, the change in the winding amount of the take-up belt 311 enables accurate statistics of the cable cutting length, providing an accurate reference for timing the grinding process. Length statistics are achieved through the synchronous transmission of the conveying assembly 2, eliminating the need for an additional independent length measuring component. This simplifies the device structure and reduces manufacturing costs. Simultaneously, the gear meshing transmission ensures statistical accuracy, avoiding problems such as inaccurate grinding time and inconsistent stripping lengths caused by measurement errors.

[0041] In some embodiments, the sensing element includes a limiting plate 36, a pointer rod 37, a first elastic element 35, a pressure sensor 39, and a first tactile switch 38. A limiting groove 34 is provided on the frame 1, and a pressure sensor 39 is provided in the limiting groove 34. One end of the limiting plate 36 is slidably disposed in the limiting groove 34. A first elastic element 35 is provided between one end of the limiting plate 36 and the pressure sensor 39. A pointer rod 37 is provided at the other end of the limiting plate 36. The pointer rod 37 and the first elastic element 35 are respectively located on both sides of the limiting plate 36 in its thickness direction. The pointer rod 37 abuts against the winding belt 311 on the second winding wheel 310. The first tactile switch 38 is disposed on the frame 1. The first tactile switch 38 and the pointer rod 37 are located on the same side of the limiting plate 36. The pressure sensor 39 is electrically connected to the adjustment assembly 5.

[0042] Specifically, the first elastic element 35 is the first spring.

[0043] A limiting groove 34 is provided on the mounting bracket 12, extending vertically. The limiting plate 36 slides within the limiting groove 34 to ensure stable movement. The pointer rod 37 is located directly above the second take-up roller 310. The bottom elliptical portion of the pointer rod 37 presses against the take-up tape 311 on the second take-up roller 310. When the take-up tape 311 on the second take-up roller 310 is wound by the first take-up roller 33, the thickness of the take-up tape on the second take-up roller 310 decreases. The first elastic member 35 applies a downward force to the limiting plate 36, meaning the pointer rod 37 is subjected to a downward force. This causes the pointer rod 37 to gradually move downward as the take-up tape 311 on the second take-up roller 310 decreases. Simultaneously, the limiting plate 36 moves downward. When it reaches its final position, the limiting plate 36 touches the first tactile switch 38. At the same time, the change in pressure of the first elastic member 35 on the limiting plate 36 also synchronously affects the change in pressure on the pressure sensor 39. When the take-up tape 311 on the first take-up roller 33 is wound by the second take-up roller 310, that is, when the thickness of the take-up tape 311 on the second take-up roller 310 increases, it pushes the pointer rod 37 upward, thereby pushing the limit plate 36 upward, which in turn squeezes the pressure sensor 39 through the first elastic element 35, increasing the pressure detected by the pressure sensor 39. The timing component 3 records the working conditions in real time and synchronously feeds back the length data and pressure data to the adjustment component as the reference for adjusting the grinding parameters.

[0044] For example, when the equipment continuously feeds and cuts cables of different lengths such as 50cm, 100cm, and 200cm, the winding belt 311 completes different winding strokes accordingly, and the timing component 3 accurately records the total cutting length and provides synchronous feedback signals to provide data support for matching different grinding durations and grinding intensities in the future.

[0045] The adjustment component 5 is electrically connected to the timing component 3 to receive timing information from the timing component 3, and the adjustment component 5 is connected to the cutting and grinding component 4 to adjust the duration for which the cutting blade 49 is in the grinding position.

[0046] The adjustment component 5 includes an insulating box 55, a first conductive block 56, a second conductive block 57, an insulating block 58, a driving component, and a second tactile switch 511. The insulating box 55 is located inside the housing 11 of the frame 1. The first conductive block 56 is fixedly installed inside the insulating box 55. The second conductive block 57 is slidably installed inside the insulating box 55 and abuts against the first conductive block 56. The first conductive block 56 and the second conductive block 57 form the grinding circuit resistance of the cutting and grinding component 4. An insulating block 58 is provided on the side of the second conductive block 57 away from the first conductive block 56. The driving component is connected to the insulating block 58. The second tactile switch 511 is located on the insulating box 55 and is opposite to the moving path of the insulating block 58. The driving component is electrically connected to the timing component 3.

[0047] During use, after receiving the cutting length information from the timing component 3, the adjusting component 5 slides along the inner side of the insulating box 55, changing the contact area with the first conductive block 56. This adjusts the resistance of the grinding-related circuits, regulates the extension and retraction of the telescopic component, and consequently adjusts the contact degree between the cutting blade and the grinding stone, achieving adaptive adjustment of the grinding intensity. When the grinding reaches the preset time, the second conductive block 57 moves the insulating block 58 to the right, triggering the second tactile switch 511 to close the grinding process, completing one grinding operation. The insulating box 55 provides insulation protection, preventing short circuits and ensuring the safe operation of the device. By changing the contact area between the first conductive block 56 and the second conductive block 57, the grinding intensity is adjusted precisely and responds quickly. The grinding intensity can be flexibly matched according to the cable cutting length, avoiding over- or under-grinding.

[0048] The adjustment assembly 5 includes a second connecting rod 59 and a third elastic element 510. The second connecting rod 59 is slidably mounted on the insulating box 55. One end of the second connecting rod 59 is connected to the insulating block 58, and the third elastic element 510 is located between the other end of the second connecting rod 59 and the insulating box 55. The third elastic element 510 has a certain elasticity. When the second conductive block 57 slides for adjustment, it will drive the second connecting rod 59 to move synchronously. During the movement of the second connecting rod 59, the third elastic element 510 is compressed or stretched. The elastic force of the third elastic element 510 can buffer and reset the second conductive block 57, ensuring smooth sliding of the second conductive block 57 and avoiding fluctuations in grinding intensity caused by jamming during the adjustment process. After grinding, the third elastic element 510 can drive the second conductive block 57 to automatically reset, preparing for the next adjustment. The second connecting rod 59 and the third elastic element 510 can improve the operational stability and adjustment accuracy of the adjustment assembly 5. The reset function can ensure continuous operation of the device, reduce manual intervention, and improve work efficiency.

[0049] The adjustment assembly 5 includes a third motor 51, a threaded rod 52, and an electromagnet rod 54. The third motor 51 is mounted on the frame 1 and is connected to the threaded rod 52. A threaded block 53 is mounted on the threaded rod 52. The threaded block 53 is located between the insulating block 58 and the second tactile switch 511. The electromagnet rod 54 is mounted on the frame 1. Both the threaded block 53 and the insulating block 58 are slidably mounted on the electromagnet rod 54. An iron ring is provided on the insulating block 58.

[0050] During polishing, the threaded rod 52 can be rotated by controlling the third motor 51. Based on the pressure information fed back by the timing component, the threaded block 53 is moved to the corresponding position. The moving threaded block 53 slides on the electromagnet rod 54 and pushes the insulating block 58, thereby adjusting the contact area between the first conductive block 56 and the second conductive block 57. When it is necessary to fix the polishing intensity, the electromagnet rod 54 is energized. An iron ring is placed on the inner side of the insulating block 58 at the contact point with the electromagnet rod 54, allowing the energized electromagnet rod 54 to attract and fix the insulating block 58, thus fixing the position of the second conductive block 57. When it is not necessary to fix the polishing intensity, the power supply to the electromagnet rod 54 is disconnected, and the third motor 51 is controlled to move the threaded block 53 stepwise. The threaded block 53 pushes the second conductive block through the insulating block. When the third motor 51 is turned off, it moves to the right and resets under the action of the third elastic element 510. When the threaded block 53 triggers the second tactile switch 511, the polishing operation stops. The reset of insulating block 58 prepares for subsequent grinding and adjustment. The threaded block 53 is made of insulating material and will not affect the movement between them.

[0051] For example, when the timing component 3 detects that the cable cutting length is too short, the adjustment component 5 reduces the contact area between the second conductive block and the first conductive block by controlling the third motor 51, thereby reducing the grinding intensity and shortening the grinding time to avoid excessive wear of the cutting blade. When continuous long-distance cutting is detected, it is determined that the wear of the cutting blade 49 is too large. The adjustment component 5 increases the contact area between the second conductive block and the first conductive block by controlling the third motor, thereby increasing the grinding intensity and extending the grinding time to fully restore the sharpness of the cutting blade 49 and adapt to different working conditions.
