Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of cable production, and more specifically, to a shaft-passing structure for a wire and cable bow stranding machine. Background Technology

[0002] In the field of wire and cable manufacturing, the cable stranding machine, as a key piece of equipment for stranding multi-strand cables, directly affects product quality and production efficiency due to the performance of its shaft-passing structure. Currently, the shaft-passing structure of traditional wire and cable stranding machines has significant defects in handling cable stranding and core arrangement.

[0003] In existing cable stranding machines, to ensure uniform stranding, the cable often needs to be wound around the main shaft multiple times. However, this multiple-winding method not only increases the risk of cable wear but also easily leads to uneven stranding tension, affecting the electrical performance and mechanical strength of the finished product. Furthermore, the fixed core placement in traditional shaft-passing structures makes it difficult to flexibly adjust according to different cable specifications, stranding process requirements, and forming conditions. When producing different types of wires and cables, operators often need to spend a significant amount of time disassembling and replacing shaft-passing assemblies, reducing production efficiency and increasing equipment maintenance costs. With the increasing demand for product diversification and customization in the wire and cable industry, the traditional shaft-passing structure of cable stranding machines can no longer meet the high-efficiency and flexible requirements of modern production. Therefore, developing a cable stranding machine shaft-passing structure that can reduce the number of times the cable is wound around the shaft and easily adjust the core placement according to the cable forming conditions is of great significance for improving the quality and efficiency of wire and cable production. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a shaft-passing structure for a wire and cable bow stranding machine, which solves the technical problem that the wire cores in the traditional shaft-passing structure are fixed in their dispersed positions, making it difficult to flexibly adjust them according to different cable specifications, stranding process requirements and forming conditions.

[0005] According to one aspect, at least one embodiment of this disclosure provides a shaft-passing structure for a wire and cable bow stranding machine, comprising:

[0006] The system comprises a base, a transmission cavity, and a rotating sleeve, wherein the transmission cavity is formed within the base and the rotating sleeve is rotatably connected within the transmission cavity.

[0007] A driving heat dissipation assembly is disposed within the rotating sleeve and the base;

[0008] A mold changing assembly is disposed outside the rotating sleeve;

[0009] The drive heat dissipation assembly includes an inner cavity, which is opened inside the base. A bottom groove is opened on one side of the bottom of the base. An external gear is arranged around the outer surface of the rotating sleeve. A drive gear that is driven by electricity is installed on one side of the base. The electric drive part of the drive gear is located in the inner cavity.

[0010] As a further technical solution, a groove is provided at the bottom of the transmission cavity, an air inlet is provided on the surface of the rotating sleeve, and an air inlet pipe is provided at the top of the bottom groove, with the air inlet pipe connected to the groove.

[0011] As a further technical solution, a locking block is provided in the groove through a vertical linear drive connection. The locking block is attached to the bottom surface of the rotating sleeve, and the contact surface between the locking block and the rotating sleeve is a frosted anti-slip surface.

[0012] As a further technical solution, the mold changing component includes an installation groove, which is formed on both ends of the rotating sleeve. A pair of splicing templates are fitted and connected inside the installation groove, and the surface of the splicing templates has several through holes.

[0013] As a further technical solution, a number of positioning blocks are provided on the inner circumference of the mounting groove, the splicing template is fitted on the positioning blocks, and a number of ear plates are provided at both ends of the outer surface of the rotating sleeve. The splicing template and the ear plates are fixedly connected by bolts.

[0014] As a further technical solution, one side of the inner cavity is an open structure, and the inner cavity is connected to the bottom groove.

[0015] As a further technical solution, a pair of anti-detachment slide rail grooves are provided around the transmission cavity, and the rotating sleeve is slidably connected in the anti-detachment slide rail grooves.

[0016] As a further technical solution, the air inlet holes are evenly distributed in a ring around the surface of the rotating sleeve.

[0017] The beneficial effects of the embodiments disclosed herein are as follows:

[0018] In this disclosure, the mold changing component precisely positions the splicing template using positioning blocks within the mounting slot, ensuring accurate perforation layout. The ear plate is bolted to the splicing template, facilitating easy disassembly and allowing for quick replacement of splicing templates to suit different cable specifications, shortening mold changeover time and adapting to diverse production needs. The sliding connection between the anti-detachment slide rail groove and the rotating sleeve ensures the stability of the splicing template during rotation, preventing offset from affecting stranding accuracy. This allows for flexible adjustment of the core distribution position across the shaft according to cable specifications, stranding process requirements, and forming conditions, solving the problems of fixed positions and cumbersome mold changes in traditional structures, thus improving production efficiency and flexibility.

[0025] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] like Figures 1-4 As shown, it illustrates a shaft-passing structure for a wire and cable bow stranding machine according to an embodiment of the present disclosure, comprising:

[0032] The base 1, the transmission cavity 2, and the rotating sleeve 3 are provided. The transmission cavity 2 is formed inside the base 1, and the rotating sleeve 3 is rotatably connected inside the transmission cavity 2.

[0033] A drive heat dissipation component 4 is disposed within the rotating sleeve 3 and the base 1;

[0034] Mold changing component 5, wherein the mold changing component 5 is disposed outside the rotating sleeve 3;

[0035] The drive heat dissipation assembly 4 includes an inner cavity 4-1, which is formed inside the base 1. A bottom groove 4-2 is formed on one side of the bottom of the base 1. An external gear 4-3 is arranged around the outer surface of the rotating sleeve 3. A drive gear 4-4, which is driven by electricity, is installed on one side of the base 1. The electric drive part of the drive gear 4-4 is located in the inner cavity 4-1. A groove 4-5 is formed at the bottom of the transmission cavity 2. An air inlet 4-6 is formed on the surface of the rotating sleeve 3. An air inlet pipe 4-7 is provided at the top of the bottom groove 4-2. The air inlet pipe 4-7 is connected to the groove 4-5. A locking block 4-8 ​​is provided in the groove 4-5 and connected by vertical linear drive. The locking block 4-8 ​​is attached to the bottom surface of the rotating sleeve 3. The contact surface between the locking block 4-8 ​​and the rotating sleeve 3 is a frosted anti-slip structure.

[0036] In some examples, a drive and heat dissipation assembly 4 is designed to achieve efficient driving and heat dissipation of the rotating sleeve 3. The electrically driven drive gear 4-4 is located in the inner cavity 4-1 of the base 1. It meshes with the external gear 4-3 on the outer surface of the rotating sleeve 3, driving the rotating sleeve 3 to rotate stably within the transmission cavity 2. The communication structure between the air inlet pipe 4-7, the groove 4-5, and the air inlet hole 4-6 allows air to flow through the bottom groove 4-2 and the groove 4-5 into the air inlet hole 4-6 of the rotating sleeve 3, forming an internal ventilation channel. This effectively removes the heat generated during bow winch operations, preventing the cable temperature from becoming too high. The vertically linearly driven locking block 4-8 ​​can be flexibly raised and lowered according to work requirements. When the locking block 4-8 ​​rises, its frosted anti-slip surface fits tightly against the bottom of the rotating sleeve 3, effectively locking it to prevent accidental rotation. When mold replacement or adjustment is required, the locking block 4-8 ​​is raised to unlock, ensuring safe and convenient operation.

[0037] The connection between the inner cavity 4-1 and the bottom groove 4-2, as well as the opening structure on one side, not only facilitates the installation and maintenance of the drive gear 4-4, but also provides space for the layout of the air intake pipe 4-7, ensuring smooth airflow for heat dissipation.

[0038] like Figures 1-4 As shown in the figure, the mold changing component 5 in this embodiment includes a mounting groove 5-1, which is formed on both ends of the rotating sleeve 3. A pair of splicing templates 5-2 are fitted inside the mounting groove 5-1. The surface of the splicing templates 5-2 is provided with several through holes 5-3. Several positioning blocks 5-4 are provided on the inner circumference of the mounting groove 5-1. The splicing templates 5-2 are fitted on the positioning blocks 5-4. Several ear plates 5-5 are provided at both ends of the outer surface of the rotating sleeve 3. The splicing templates 5-2 and the ear plates 5-5 are fixedly connected by bolts.

[0039] In some examples, a mold replacement assembly 5 is designed to meet the production needs of wires and cables of different specifications. The mounting slots 5-1 on both sides of the rotating sleeve 3 provide installation space for the splicing template 5-2. Positioning blocks 5-4 are distributed around the mounting slots 5-1, precisely defining the installation position of the splicing template 5-2 and ensuring accurate layout of the perforations 5-3. Operators can quickly remove the old template by unscrewing the bolts between the ear plate 5-5 and the splicing template 5-2, fit the new splicing template 5-2 of the appropriate specification onto the positioning blocks 5-4, and then secure it with bolts to complete the template replacement.

[0040] This modular connection method effectively shortens mold changeover time, allowing the equipment to quickly switch between producing wires and cables of different specifications. Simultaneously, the sliding connection between the anti-detachment slide rail 6 and the rotating sleeve 3 ensures the flexible rotation of the rotating sleeve 3 while preventing radial displacement during high-speed operation, thus ensuring stable operation of the splicing template 5-2 and guaranteeing cable stranding accuracy.

[0041] For example, such as Figure 3 As shown, one side of the inner cavity 4-1 is an open structure, and the inner cavity 4-1 is connected to the bottom groove 4-2.

[0042] In some examples, the opening structure allows external air to be introduced into the inner cavity 4-1, which can dissipate the heat generated by the motor that drives the gear 4-4, effectively protecting the motor and ensuring normal operation.

[0043] For example, such as Figure 3 As shown, a pair of anti-detachment slide rail grooves 6 are provided around the inside of the transmission cavity 2, and the rotating sleeve 3 is slidably connected in the anti-detachment slide rail grooves 6.

[0044] In some examples, the anti-detachment slide rail groove 6, which is formed around the circumference of the transmission cavity 2, fits tightly with the rotating sleeve 3, providing stable guidance for the rotation of the rotating sleeve 3. The structure of the slide rail groove can limit the radial displacement generated by the rotating sleeve 3 during rotation, ensuring that the rotating sleeve 3 always maintains a precise rotation trajectory. This prevents the splicing template 5-2 from being affected by the shaking of the rotating sleeve 3 during operation, thus ensuring the quality of cable stranding.

[0045] For example, such as Figure 3 As shown, the air inlets 4-6 are evenly distributed in a ring around the surface of the rotating sleeve 3.

[0046] In some examples, the air inlets 4-6 are evenly distributed in a ring around the surface of the rotating sleeve 3. This layout allows airflow to evenly cover the interior of the rotating sleeve 3, avoiding heat dissipation blind spots. The uniform ventilation effect can effectively reduce the temperature of the rotating sleeve 3 and the internal cables during the twisting process, maintaining the stable operation of the equipment.

[0047] In practical use: After fixing the base 1, a transmission cavity 2 is opened inside the base 1. The rotating sleeve 3 is rotatably connected to the transmission cavity 2. The anti-detachment slide rail groove 6 around the transmission cavity 2 is slidably connected to the rotating sleeve 3 to ensure the stable rotation of the rotating sleeve 3. The inner cavity 4-1 of the drive heat dissipation component 4 is opened inside the base 1. A bottom groove 4-2 is opened on one side of the bottom of the base 1. An external gear 4-3 is set around the outer surface of the rotating sleeve 3. An electrically driven drive gear 4-4 is installed on one side of the base 1. The electric drive part of the drive gear 4-4 is located in the inner cavity 4-1 and meshes with the external gear 4-3. A groove 4-5 is opened at the bottom of the transmission cavity 2. An annularly distributed air inlet hole 4-6 is opened on the surface of the rotating sleeve 3. An air inlet pipe 4-7 is set at the top of the bottom groove 4-2 and is connected to the groove 4-5. A locking block 4-8 ​​is connected to the groove 4-5 through a vertical linear drive. The locking block 4-8 ​​fits against the bottom of the rotating sleeve 3, and the contact surface is a frosted anti-slip structure. The mounting slots 5-1 of the mold changing component 5 are located on both ends of the rotating sleeve 3. Positioning blocks 5-4 are arranged around the circumference of the mounting slots 5-1. A pair of splicing templates 5-2 are fitted onto the positioning blocks 5-4. Ear plates 5-5 are provided at both ends of the outer surface of the rotating sleeve 3. The splicing templates 5-2 and ear plates 5-5 are fixed with bolts. Several through holes 5-3 are formed on the surface of the splicing templates 5-2. In use, the wire core is fed through the through holes 5-3, and the main shaft passes through the center of the splicing templates 5-2, driving the rotating sleeve 3 to rotate via the drive gear 4-4. During this process, the air inlet pipe 4-7 is connected to the air supply equipment, continuously blowing air into the rotating sleeve 3. The air is cooled through the bottom groove 4-2, the groove 4-5, and the air inlet hole 4-6. The locking block 4-8 ​​can be raised and lowered to lock or unlock the rotating sleeve 3. When the mold needs to be replaced, the bolts are removed to remove the old splicing template 5-2, and the new template is installed and fixed again with bolts.
