Description

Technical Field

[0001] This utility model relates to the field of wire and cable processing technology, specifically to a core straightening device for wire and cable processing. Background Technology

[0002] As key wire products for power transmission, information transmission, and electromagnetic energy conversion, wires and cables are widely used in various fields of modern society. From power transmission in urban power grids to signal transmission in communication networks, the performance and quality of wires and cables directly affect the stable operation of the entire system. In the wire and cable processing flow, core straightening is a crucial step. Its purpose is to straighten the originally coiled cable core into a straight shape, laying the foundation for subsequent processes such as insulation coating, overall protective layer, and outer sheath, ensuring that the finished cable has good electrical and mechanical properties.

[0003] A search revealed that Chinese patent application CN222817827U discloses a core material straightening machine for wire and cable processing. By rotating a rotating gear column, multiple driven gear plates move upward or downward simultaneously, causing the moving wheels and fixed wheels to move closer or further apart at the same time. This achieves simultaneous adjustment of multiple moving wheels, ensuring that the moving distances of the multiple moving wheels are the same, reducing errors in the moving wheel adjustment process, and improving adjustment efficiency.

[0004] However, the following technical problems still exist when implementing the above technical solutions: the inability to clamp and fix the wires and cables will lead to unstable fixing of the core material, causing the straightening device to twist and damage the wires and cables. In addition, since the surface of the cable core material often has impurities such as mineral powder attached during the processing, if it is not cleaned, the core material with mineral lumps will directly enter the straightening process, which will cause more serious bending and creases in the core material.

[0005] Therefore, the problem that this utility model urgently needs to solve is to provide a core straightening device for wire and cable processing that can stably clamp cables of different diameters during use, and can also clean the cable surface to avoid impurities affecting subsequent processing, thereby improving the overall processing quality of the cable. Utility Model Content

[0006] To address the aforementioned technical problems, the purpose of this utility model is to overcome the limitations of existing technologies that cannot clamp and fix wires and cables, leading to unstable core material fixation and causing twisting damage to the wires and cables by the straightening device. Furthermore, during cable core material processing, impurities such as mineral powder often adhere to the surface. If these impurities are not cleaned, the core material with mineral clumps entering the straightening stage will result in more severe bending and creases. Therefore, this invention provides a core material straightening device for wire and cable processing that can stably clamp cables of different diameters and clean the cable surface to prevent impurities from affecting subsequent processing, thereby improving the overall processing quality of the cable.

[0019] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0020] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0021] Reference Figures 1-6 As shown, a core material straightening device for wire and cable processing includes: a first straightening seat 101 and a second straightening seat 102, which are fixedly mounted adjacently on a base 100 for straightening the cable body 103 at multiple angles. Both the first straightening seat 101 and the second straightening seat 102 are provided with straightening mechanisms 400 for straightening the cable body 103. Furthermore, a clamping mechanism 200 for fixing cables of different diameters and a cleaning mechanism 300 for cleaning the cable surface are sequentially arranged on the base 100 in front of the first straightening seat 101 and the second straightening seat 102. The clamping mechanism 200 includes: a clamping seat 202, on which a first turntable 203 is rotatably mounted, and multiple sets of rotating rods 206 that slide in cooperation with the first turntable 203 are hinged along the circumferential direction on the clamping seat 202, and a clamping roller 207 that contacts the surface of the cable body 103 is rotatably mounted at the top of the rotating rod 206.

[0022] In use, according to the diameter of the cable body 103 to be processed, the first turntable 203 on the clamping seat 202 is rotated. Since the rotating rod 206 is hinged along the circumference of the clamping seat 202 and slides with the first turntable 203, the rotation of the first turntable 203 will drive multiple sets of rotating rods 206 to rotate synchronously, causing the clamping rollers 207 at the top of the rotating rods 206 to move closer to or away from the cable body 103 until the multiple sets of clamping rollers 207 are in close contact with the surface of the cable body 103, thus completing the fixation of the cable. One end of the cable body 103 is then passed through the adjusted clamping mechanism 200, so that it is stably clamped by the clamping rollers 207. Subsequently, the cable body 103 enters the cleaning mechanism 300, which cleans impurities, dust, etc. on the surface of the cable to prepare for the subsequent straightening process. After cleaning, the cable body 103 first enters the first straightening seat 101, where the straightening mechanism 400 performs straightening treatment on the cable at a specific angle. Next, the cable body 103 continues to move to the second straightening seat 102. The straightening mechanism 400 on the second straightening seat 102 straightens the cable again from different angles. Through the synergistic effect of the first straightening seat 101 and the second straightening seat 102, the cable body 103 is straightened at multiple angles.

[0023] Reference Figures 3-4 As shown, the clamping mechanism 200 further includes: a fixed seat 201 fixedly installed on the base 100, the clamping seat 202 fixedly installed on the fixed seat 201, and a second turntable 204 fixedly installed on the first turntable 203 by a support rod. A sliding sleeve 205 corresponding to the rotating rod 206 is fixedly provided between the first turntable 203 and the second turntable 204. The rotating rod 206 is slidably sleeved in the sliding sleeve 205. The clamping seat 202 is provided with a driving mechanism 500 for driving the first turntable 203 and the second turntable 204 to rotate, thereby driving the rotating rod 206 to rotate and adjusting the clamping distance.

[0024] In the above scheme, when it is necessary to adjust the clamping distance of the clamping mechanism 200, the drive mechanism 500 on the clamping seat 202 is activated, and the drive mechanism 500 drives the first turntable 203 and the second turntable 204 to rotate synchronously. Since the rotating rod 206 is slidably sleeved in the sliding sleeve 205 between the first turntable 203 and the second turntable 204, and the rotating rod 206 is hinged along the circumferential direction of the clamping seat 202, the rotation of the first turntable 203 and the second turntable 204 will apply a force to the rotating rod 206 through the sliding sleeve 205, causing the rotating rod 206 to rotate around the hinge point. During the rotation of the rotating rod 206, the clamping roller 207 at its top end moves closer to or further away from the cable body 103, thereby realizing the adjustment of the clamping distance.

[0025] Reference Figure 4 As shown, the drive mechanism 500 includes: a fixed block 501 fixedly installed on the clamping seat 202, a threaded rod 502 rotatably passing through the fixed block 501, a threaded block 504 threadedly sleeved on the threaded rod 502, a connecting rod 505 hinged on the threaded block 504, one end of the connecting rod 505 being hinged to the first turntable 203, and a throttle 503 fixedly installed at the top end of the threaded rod 502.

[0026] In the above scheme, when the clamping distance needs to be adjusted, the operator rotates the handle 503 at the top of the threaded rod 502. The handle 503 drives the threaded rod 502 to rotate within the fixed block 501. The rotation of the threaded rod 502 causes the threaded block 504 to move axially along the threaded rod 502. When the threaded block 504 moves, its hinged connecting rod 505 moves accordingly. The connecting rod 505 pulls or pushes the first turntable 203 to rotate around its center. The rotation of the first turntable 203 drives the second turntable 204 to rotate synchronously, which in turn drives the rotating rod 206 to rotate through the sliding sleeve 205, causing the clamping roller 207 to move closer to or away from the cable body 103, thus completing the adjustment of the clamping distance.

[0027] Reference Figure 5 As shown, the cleaning mechanism 300 includes: a cleaning seat 301 fixedly installed on the base 100, the cleaning seat 301 having an avoidance groove 302 coaxially arranged with the clamping seat 202, and the inner sidewall of the avoidance groove 302 being fixedly provided with a plurality of cleaning brush heads 303 that contact the surface of the cable body 103.

[0028] In the above scheme, when the cable body 103 is conveyed to the cleaning mechanism 300 by the clamping mechanism 200, the cable body 103 passes through the clearance groove 302 on the cleaning seat 301. Since the clearance groove 302 is coaxially arranged with the clamping seat 202, the cable body 103 maintains axial stability during the conveying process, and the multiple sets of cleaning brush heads 303 on the inner sidewall of the clearance groove 302 are in close contact with the surface of the cable body 103. As the cable body 103 continues to move, the cleaning brush heads 303 brush away impurities, dust, etc. on the cable surface, completing the cleaning of the cable surface. The cleaned cable continues to move towards the straightening mechanism 400.

[0029] Reference Figures 5-6 As shown, the straightening mechanism 400 includes: multiple sets of first straightening rollers 402 rotatably mounted on the first straightening seat 101 and the second straightening seat 102 at intervals; the first straightening seat 101 and the second straightening seat 102 are respectively provided with sliding grooves 404; sliding seats 401 are slidably disposed in the sliding grooves 404; and the bottom surface of the sliding grooves 404 is provided with guide grooves 403 for the sliding seats 401 to slide; second straightening rollers 407 corresponding one-to-one with the first straightening rollers 402 are rotatably disposed on the sliding seats 401; and the first straightening seat 101 and the second straightening seat 102 are provided with adjusting components for driving the sliding seats 401 to slide in the sliding grooves 404 to straighten cable bodies 103 of different diameters.

[0030] In the above scheme, based on the diameter of the cable body 103, the sliding seat 401 is driven by an adjusting component to slide within the grooves 404 of the first straightening seat 101 and the second straightening seat 102. The sliding seat 401 moves stably along the guide groove 403, causing the second straightening roller 407 on it to move closer to or further away from the corresponding first straightening roller 402, until the distance between the first straightening roller 402 and the second straightening roller 407 matches the cable diameter. When the cable body 103 enters the straightening mechanism 400, multiple sets of first straightening rollers 402 and second straightening rollers 407 clamp and straighten the cable. During the cable movement, bending deformation is eliminated by compression at different angles. The straightening mechanisms 400 on the first straightening seat 101 and the second straightening seat 102 work together to achieve multi-angle straightening.

[0031] Reference Figure 6 As shown, the adjusting component includes a screw 405 threaded through the sidewalls of the first straightening seat 101 and the second straightening seat 102, the top end of the screw 405 being rotatably connected to the sidewall of the sliding seat 401 via a bearing 406.

[0032] In the above scheme, when adjusting the distance between the first straightening roller 402 and the second straightening roller 407, the screw 405, whose threads pass through the side walls of the first straightening seat 101 and the second straightening seat 102, is rotated. The screw 405 pushes or pulls the sliding seat 401 through the bearing 406, causing it to slide along the guide groove 403 within the slide groove 404. The sliding seat 401 drives the second straightening roller 407 to move closer to or further away from the first straightening roller 402 until the distance between them matches the diameter of the cable body 103. After adjustment, the screw 405 is fixed in position under the self-locking action of the thread, and the sliding seat 401 and the second straightening roller 407 remain stable, ensuring a constant clamping force on the cable during the straightening process.

[0033] Reference Figures 1-6 As shown, the first straightening roller 402 and the second straightening roller 407 are spindle-shaped, with large ends and a small middle.

[0034] In the above scheme, the spindle-shaped first straightening roller 402 and the second straightening roller 407 contact the cable surface. Due to their shape, which is larger at both ends and smaller in the middle, they can form a good fit with the cable surface of different diameters. During the cable movement, the straightening rollers apply the main straightening force to the middle of the cable through the thinner middle part, while the thicker ends provide auxiliary restraint to prevent the cable from deviating.

[0035] In summary, the present invention provides a core straightening device for wire and cable processing. During use, the clamping distance of the clamping mechanism 200 is adjusted by the drive mechanism 500 according to the diameter of the cable body 103 to be processed. Rotating the handle 503 at the top of the threaded rod 502 causes the threaded rod 502 to rotate within the fixed block 501. The threaded block 504 moves along the threaded rod 502, pushing the first turntable 203 to rotate via the connecting rod 505. The first turntable 203 then drives the second turntable 204 to rotate synchronously. The rotating rod 206 slides within the sliding sleeve 205 and rotates with the turntable, causing the clamping rollers 207 at the top to approach the cable body 103 until multiple sets of clamping rollers 207 are in close contact with the cable surface, completing the clamping and fixing. One end of the cable body 103 is then passed through the clamping rollers 207 of the clamping mechanism 200 and moved towards the cleaning mechanism 300 under traction. When the cable passes through the clearance groove 302 of the cleaning seat 301, multiple sets of cleaning brush heads 303 on the inner wall contact the cable surface, brushing away surface impurities and dust as the cable moves. After cleaning, the cable continues to be conveyed to the straightening mechanism 400. The straightening mechanism 400 on the first straightening seat 101 and the second straightening seat 102 is adjusted according to the diameter of the cable body 103. The screw 405 is rotated, and the sliding seat 401 is pushed along the guide groove 403 of the slide groove 404 through the bearing 406, so that the second straightening roller 407 on the sliding seat 401 approaches the first straightening roller 402, until the distance between the spindle-shaped first straightening roller 402 and the second straightening roller 407 matches the cable diameter. The screw 405 is then stopped, the sliding seat 401 is fixed in position, and the cleaned cable body 103 first enters the straightening mechanism 400 of the first straightening seat 101. Multiple sets of first straightening rollers 402 and second straightening rollers 407 cooperate to perform the first angle straightening of the cable. Subsequently, the cable continues to move to the straightening mechanism 400 of the second straightening seat 102. The straightening roller group on the second straightening seat 102 straightens the cable again from different angles. Through the synergistic effect of the two straightening seats, the cable body 103 is straightened at multiple angles, and the straightening process of the cable core material is finally completed.

[0036] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0037] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction.
