Description

Technical Field

[0001] The utility model belongs to the field of cable processing, and particularly relates to a core straightening device for wire and cable processing. Background Art

[0002] As a key wire product for power transmission, information transmission, and electromagnetic energy conversion, wire and cable are widely used in various fields of modern society. From the power transmission of urban power grids to the signal transmission of communication networks, the performance and quality of wire and cable directly affect the stable operation of the entire system. In the processing process of wire and cable, core straightening is a crucial process, the purpose of which is to correct the original curled inner core of the cable into a straight form, laying a foundation for subsequent processes such as coating the insulator, the overall protective layer, and the outer protective layer, and ensuring that the finished cable has good electrical and mechanical properties.

[0003] Currently, there are already various core straightening devices for wire and cable processing on the market. Taking a core straightening machine for wire and cable processing disclosed in a Chinese patent (Publication No.: CN222817827U) as an example, this device realizes the simultaneous adjustment of multiple driving wheels through the cooperation of structures such as the square grooves, driven tooth plates, driving wheels, and rotating tooth columns on the first straightening plate and the second straightening plate, improving the adjustment efficiency and reducing the adjustment error to a certain extent. However, there are still many problems to be solved in the existing technology:

[0004] On the one hand, when the bending degree of the core to be straightened is large, the traditional straightening machine faces severe challenges during operation. The straightening machine mainly relies on the roller to apply bending and tensile forces to the core to achieve straightening. However, for cores with excessive bending, the pressure generated during the straightening process is extremely likely to exceed the yield strength of the core material; especially for common metal cable cores such as copper and aluminum, under the action of excessive pressure, the internal metal structure will suffer irreversible damage. In the light case, the core will have plastic deformation and cannot be restored to the ideal straight state, affecting the appearance quality and dimensional accuracy of the cable; in the severe case, the core will break, directly resulting in the scrapping of the entire section of the cable, greatly increasing the production cost and reducing the production efficiency;

[0005] On the other hand, since mineral powder and other impurities often adhere to the surface of the cable core material during the processing process, if not cleaned thoroughly, the mineral powder will agglomerate on the surface of the core material. In traditional straightening equipment, there is a lack of an effective cleaning mechanism, allowing the core material with mineral agglomerates to directly enter the straightening link; during the straightening process, these agglomerates will move along with the core material and cause local compression on the core material, resulting in more serious bending creases on the core material, not only seriously affecting the straightening effect, but also possibly forming defects such as scratches and pits on the surface of the core material, further reducing the insulation performance and mechanical strength of the cable and posing a safety hazard;

[0006] Therefore, a core straightening device for wire and cable processing is needed to solve the above problems. Summary of the Utility Model

[0007] The purpose of the embodiments of the present utility model is to provide a core straightening device for wire and cable processing to solve the problems raised in the above background technology.

[0008] To achieve the above purpose, the present utility model provides the following technical solutions:

[0009] A core straightening device for wire and cable processing includes a straightening device main body, a fixed pipe, a protective member, and a cleaning component. The fixed pipe is connected to the top of the straightening device main body;

[0010] The protective member includes a first protective component and a second protective component. The first protective component includes two first fixing frames, which are connected to the outside of the fixed pipe. A first rotating rod is rotatably connected in each of the two first fixing frames, and one end of the two first rotating rods close to each other is connected to the same first conical pipe;

[0011] The second protective component includes two second fixing frames, which are connected to the outside of the fixed pipe. A second rotating rod is rotatably connected in each of the two second fixing frames, and one end of the two second rotating rods close to each other is connected to the same second conical pipe;

[0012] The cleaning component includes a motor, which is connected to the top of the fixed pipe. The output shaft of the motor is connected to a first gear, the first gear meshes with a second gear, a rotating pipe is connected inside the second gear, a cleaning brush is connected inside the rotating pipe, and the rotating pipe is connected to the fixed pipe through a bearing.

[0013] A further technical solution further includes a protective cover, which is connected above the straightening device main body.

[0014] A further technical solution is that both the first gear and the second gear are arranged inside the protective cover.

[0015] A further technical solution is that the positions of the first conical pipe and the second conical pipe correspond to each other, and the second conical pipe is arranged between the first conical pipe and the fixed pipe.

[0017] A further technical solution is that the second conical pipe is communicated with the fixed pipe through the first conical pipe.

[0018] Compared with the prior art, the beneficial effects of the present utility model are:

[0019] In this utility model, through the unique structural design of the first conical tube and the second conical tube, when the bent cable core passes through, if the core is bent, it will drive the first conical tube and the second conical tube to rotate, changing their relative angles. During the process of the cable core being pulled by the straightening equipment main body, the first conical tube and the second conical tube will gradually rotate and return to the position coaxial with the fixed tube. During this process, the bending angle of the core is gradually reduced, effectively alleviating the excessive pressure generated by traditional equipment when straightening cores with large bending degrees, avoiding damage or fracture of the core due to excessive force, and significantly improving the success rate and quality of core straightening;

[0020] In this utility model, impurities are thoroughly cleaned: In the cleaning component, the motor drives the first gear to rotate. Through gear meshing transmission, it drives the second gear, the rotating tube, and the cleaning brush to rotate synchronously. The rotating cleaning brush can clean impurities such as mineral powder attached to the surface of the cable core comprehensively and efficiently, ensuring the cleanliness of the core surface, avoiding secondary damage to the core caused by impurity caking during the straightening process, guaranteeing the straightening effect and surface quality of the core, and thus improving the performance and quality of the finished wire and cable products;

[0021] In this utility model, the working environment is optimized: The setting of the protective cover can not only prevent the impurities swept out by the cleaning brush from splashing everywhere, but also prevent external dust from entering the equipment, avoiding impurities and dust from adhering to the surfaces of transmission components such as the first gear and the second gear, reducing component wear, lowering the equipment maintenance cost, extending the service life of the equipment, and keeping the working environment clean;

[0022] In this utility model, the structure is compact and reasonable: The overall equipment structure is designed compactly, and the layout of each component is scientific and reasonable.

[0029] In order to make the purpose, technical solution and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0030] The following describes in detail the specific implementation of the present utility model in conjunction with specific embodiments.

[0031] Embodiment 1

[0032] As Figures 1-4 shown, the embodiment of the present utility model provides a core material straightening equipment for wire and cable processing, including a straightening equipment main body 1, a fixed pipe 2, a protective part 3 and a cleaning component 4. The fixed pipe 2 is connected to the top of the straightening equipment main body 1. The fixed pipe 2 is firmly connected to the top of the straightening equipment main body 1 and serves as the basic carrier of the core material transmission and protection and cleaning structure;

[0033] The protective part 3 includes a first protective component 31 and a second protective component 32. The first protective component 31 includes two first fixing frames 311. The two first fixing frames 311 are connected to the outside of the fixed pipe 2. A first rotating rod 312 is rotatably connected in each of the two first fixing frames 311. One ends of the two first rotating rods 312 close to each other are connected to the same first conical pipe 313;

[0034] The second protective component 32 includes two second fixing frames 321. The two second fixing frames 321 are connected to the outside of the fixed pipe 2. A second rotating rod 322 is rotatably connected in each of the two second fixing frames 321. One ends of the two second rotating rods 322 close to each other are connected to the same second conical pipe 323. The first conical pipe 313 and the second conical pipe 323 are corresponding in position, and the second conical pipe 323 is located between the first conical pipe 313 and the fixed pipe 2 to form a continuous core material guiding channel;

[0035] The cleaning component 4 includes a motor 41. The motor 41 is connected to the top of the fixed pipe 2. The output shaft of the motor 41 is connected to the first gear 42. The first gear 42 meshes with the second gear 43 to realize the transmission and conversion of power;

[0036] A rotating tube 44 is connected inside the second gear 43, and a cleaning brush 45 is connected inside the rotating tube 44. The rotating tube 44 is connected to the fixed tube 2 through a bearing 46 to ensure that the rotating tube 44 can rotate flexibly inside the fixed tube 2. A cleaning brush 45 for cleaning the surface of the core material is also provided inside the rotating tube 44.

[0037] In this embodiment, one end of the cable passes through the second tapered tube 323, the first tapered tube 313, the fixed tube 2, the rotating tube 44, and the protective cover 5 in sequence and moves into the straightening device main body 1. When the working straightening device main body 1 drives the cable to move and straighten the cable, the cable to be straightened can move inside the second tapered tube 323, the first tapered tube 313, the fixed tube 2, and the rotating tube 44. When a bend appears in the part to be straightened, the bent cable will drive the first tapered tube 313 and the second tapered tube 323 to rotate, so that the first tapered tube 313 and the second tapered tube 323 are not on the same axis. When the cable is pulled by the working straightening device main body 1, the pulled cable will pull the first tapered tube 313 and the second tapered tube 323 to rotate, so that the first tapered tube 313 and the second tapered tube 323 gradually rotate to a position coaxial with the fixed tube 2. During this process, the angle of the bent cable will gradually decrease, so that the cable with a small degree of bending will smoothly pass through the rotating tube 44 and the protective cover 5 and move into the straightening device main body 1;

[0038] Moreover, since the ends of the first tapered tube 313 and the second tapered tube 323 away from the fixed tube 2 are both tapered, the bent cable can smoothly enter the first tapered tube 313 and the second tapered tube 323 through the tapered part. And during this process, the edges of the first tapered tube 313 and the second tapered tube 323 are not likely to damage the cable.

[0039] During this process, control the motor 41 to work. The working motor 41 drives the first gear 42 to rotate. The rotating first gear 42 drives the second gear 43 to rotate. The rotating second gear 43 drives the rotating tube 44 to rotate. The rotating rotating tube 44 drives the cleaning brush 45 to rotate outside the cable. The rotating cleaning brush 45 can clean the dirt attached to the outside of the cable, so that the cable after cleaning the dirt is not likely to affect the straightening quality due to the dirt attached to its surface.

[0040] Specifically, the positions of the first tapered tube 313 and the second tapered tube 323 correspond to each other, and the second tapered tube 323 is arranged between the first tapered tube 313 and the fixed tube 2.

[0041] In this embodiment, the pulled cable will pull the first tapered tube 313 and the second tapered tube 323 to rotate, so that the first tapered tube 313 and the second tapered tube 323 gradually rotate to a position coaxial with the fixed tube 2.

[0042] Specifically, the bearing 46 is arranged in the fixed pipe 2, and the fixed pipe 2 is communicated with the rotating pipe 44.

[0043] In this embodiment, the bearing 46 can limit and fix the rotating pipe 44 and the fixed pipe 2 together.

[0044] Specifically, the second conical pipe 323 is communicated with the fixed pipe 2 through the first conical pipe 313.

[0045] In this embodiment, the cable can sequentially pass through the second conical pipe 323 and the first conical pipe 313 and enter the fixed pipe 2.

[0046] Embodiment 2

[0047] Please refer to Figures 1-4 , the difference between this embodiment and Embodiment 1 is that: it further includes a protective cover 5, the protective cover 5 is connected above the straightening equipment main body 1, and the first gear 42 and the second gear 43 are both arranged in the protective cover 5.

[0048] In this embodiment, the protective cover 5 can block the dirt swept out by the cleaning brush 45, and can also block the external dust, so that the external dirt and the swept-out dirt are not easily attached to the outside of the first gear 42 and the second gear 43, thereby causing pollution to them.

[0049] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
