Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable production, and in particular to a cable stranding auxiliary device. Background Technology
[0002] Cable stranding is a core process in the production of wires and cables, and the tightness of the stranding directly determines the structural stability, electrical performance, and mechanical protection capabilities of the cable. During the cable stranding process, an auxiliary pressing device is used to apply pressure to the stranded cable, squeezing the gaps between the cable cores to ensure that the stranded cable structure is compact and not easily loosened.
[0003] In existing technologies, cable stranding and pressing devices mostly adopt a fixed radial pressure roller structure. The pressure rollers of such devices can usually only apply static pressure along the radial direction of the cable and cannot rotate synchronously to apply pressure in accordance with the spiral direction of cable stranding. This results in the pressure rollers squeezing the cable in a direction inconsistent with the stranding direction, making it difficult to continuously squeeze the gap along the stranding spiral trajectory. This can easily lead to problems such as insufficient gaps and tightness after cable stranding, affecting subsequent key performance aspects such as sheathing and bending resistance.
[0004] Meanwhile, existing pressure roller assemblies generally lack wear compensation mechanisms: pressure rollers are mostly made of easily worn materials such as rubber, and after long-term friction with the cable surface, dimensional wear will occur. The traditional fixed-installation pressure roller structure cannot automatically compensate for wear, causing the pressure roller's holding force on the cable to decrease rapidly with wear. This requires frequent machine stops to adjust the pressure roller position or replace the pressure roller, which not only interrupts the production rhythm and reduces production efficiency, but also easily leads to uneven holding force due to errors in manual adjustment, affecting the consistency of stranding quality. In traditional cable stranding, sufficient stranding tension is maintained entirely by the stranding pull. However, this method requires high stability in the stranding process and is prone to problems such as increased local stranding gaps, which affect quality. Utility Model Content
[0005] The purpose of this utility model is to provide a cable stranding auxiliary device to solve the problem of low local compactness in the traditional stranding process.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cable stranding auxiliary device, including a fixed frame, a rotating frame rotatably connected to the fixed frame, a rotating disk slidably disposed on the inner wall of the rotating frame, and a pressure roller assembly that is pressed and rotated by the rotating frame to move the axis of rotation. The rotating frame is fixed with a power input pulley, which drives the rotating frame to rotate in the direction of the cable forming spiral. The rotating frame holds the pressure roller assembly and the rotating disk to rotate, providing the pressure roller assembly with continuous pressure towards the axis to hold the cable and squeeze its gaps.
[0007] As a further description of the above technical solution: the rotating frame includes a base cylinder that rotates through a fixed frame, the outer side wall of the base cylinder has a plurality of pressing parts arranged in a rotating array, the outer edge of the plurality of pressing parts is integrally formed with a fixed extension, and the fixed extension is fitted with a limiting ear that cooperates with the limiting rotating disk to slide on the fixed extension by screws.
[0008] As a further description of the above technical solution: the inner wall of the pressing part is arc-shaped and presses the pressure roller assembly.
[0009] As a further description of the above technical solution: the pressure roller assembly includes a wheel seat, through which a rotating shaft is rotatably passed, and a wheel body is sleeved on the rotating shaft and fixed by a mounting component on the rotating shaft.
[0010] As a further description of the above technical solution: the rotating disk is provided with several strip-shaped sliding holes for limiting the sliding of the wheel seat.
[0011] As a further description of the above technical solution: the edge of the wheel facing the cable is provided with an arc-shaped chamfer, and the wheel is made of rubber.
[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: The swivel frame rotates synchronously along the cable stranding spiral direction, and the pressure roller assembly continuously applies axial pressure to the cable in the stranding direction, squeezing the cable stranding gaps, effectively improving the tightness of the cable stranding, and avoiding problems such as looseness and excessive gaps.
[0013] The arc-shaped structure of the clamping part can always clamp the wheel seat of the clamping roller assembly. Even if the wheel body wears down due to long-term use, it can still ensure that the wheel body continues to be in contact with the cable surface, avoiding wear that leads to a decrease in clamping force and ensuring the stability and consistency of clamping force during the production process.
[0014] The wheel body is assembled with the shaft via mounting parts. Wearing wheels can be quickly replaced by removing the mounting parts without disassembling the entire structure, reducing maintenance difficulty, minimizing equipment downtime, and controlling maintenance costs.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] like Figure 1 - Figure 5 As shown, the present invention provides a cable stranding auxiliary device, including a fixed frame 1, a rotating frame 2 rotatably connected to the fixed frame 1, a rotating disk 3 slidably disposed on the inner wall of the rotating frame 2, and a pressure roller assembly 4 rotatably passing through the rotating disk 3 and subjected to the pressure of the rotating frame 2 to rotate the axis. The rotating frame 2 is fixed with a power input pulley 5, which drives the rotating frame 2 to rotate in the direction of the cable forming spiral. The rotating frame 2 presses the pressure roller assembly 4 and the rotating disk 3 to rotate, providing the pressure roller assembly 4 with continuous pressure towards the axis to press the cable and squeeze its gaps.
[0019] Power is input to the spinning frame 2 via pulley 5, causing the spinning frame 2, spinning disk 3, and pressure roller assembly 4 to rotate synchronously. The pressure roller assembly 4 then continuously applies pressure along the spiral direction of the cable, providing stable, continuous, and consistent axial holding force during cable stranding. This causes the cable strands to automatically align densely along the spiral path during extrusion, significantly improving stranding tightness and uniformity. The arc-shaped inner wall of the holding part 22 continuously applies pressure to the pressure roller assembly 4 as the spinning frame 2 rotates. This automatically compensates for pressure wear on the roller body 43, ensuring reliable contact between the pressure roller assembly 4 and the cable surface. This prevents pressure reduction due to wear and guarantees long-term stability of stranding quality. Furthermore, the roller body 43 of the pressure roller assembly 4 can be quickly disassembled and replaced via mounting parts 44, improving maintenance convenience and production line continuity while ensuring holding reliability. This results in excellent durability and stable stranding production capacity.
[0020] Specifically, such as Figure 4As shown, the rotating frame 2 includes a base cylinder 21 that rotates through the fixed frame 1. The outer side wall of the base cylinder 21 has a plurality of pressing parts 22 arranged in a rotating array. The outer edge of the plurality of pressing parts 22 is integrally formed with a fixed extension 23. The fixed extension 23 is fitted with a limiting ear 24 that slides with the limiting rotating disk 3 by screws.
[0021] The limiting ear 24 is located below the fixed extension 23. After it is fixed, the limiting disc 3 will not slip when it rotates inside it.
[0022] The axial continuous pressing of the pressure roller assembly 4 by the rotating frame 2, and its synchronous rotation along the stranding helix direction, achieves continuous compression and tight forming of the cable gap, thereby ensuring the stability of the stranding quality. The arc-shaped structure of the pressing part 22 can still maintain effective pressure after the wheel body 43 wears, and also has the ability to quickly replace the wheel body 43, significantly improving the reliability and long-term stability of the device.
[0023] The fixed extension 23 can synchronize multiple pressing parts 22, improve structural strength, and fit the rotating disk 3 to maintain its rotational stability.
[0024] Specifically, such as Figure 5 As shown, the inner wall of the pressing part 22 is arc-shaped and presses the pressure roller assembly 4.
[0025] The wheel seat 41 of the pressure roller assembly 4 is in direct contact with the inside of the pressure holding part 22, so that during the rotation, the rotating frame 2 pushes the rotating disk 3 to rotate synchronously through the wheel seat 41, and provides a thrust towards the axis of the wheel seat 41 based on the inner arc surface.
[0026] Specifically, such as Figure 3 As shown, the pressure roller assembly 4 includes a wheel seat 41, through which a rotating shaft 42 is rotatably driven. A wheel body 43 is sleeved on the rotating shaft 42 and fixed by a mounting piece 44 on the rotating shaft 42.
[0027] By setting the wheel seat 41, which slides within the sliding hole 6, the wheel seat 41 supports the rotating shaft 42. The rotating shaft 42 can support the rotation of the wheel body 43, and the excessively worn wheel body 43 can be easily replaced through the mounting part 44.
[0028] Specifically, such as Figure 5 As shown, the rotary disk 3 has several strip-shaped sliding holes 6 for limiting the sliding of the wheel seat 41.
[0029] The sliding hole 6 is located on the rotating disk 3 and faces the axis, so as to guide the directional movement of the wheel seat 41.
[0030] Specifically, such as Figure 3 As shown, the edge of the wheel body 43 facing the cable has an arc-shaped chamfer, and the wheel body 43 is made of rubber.
[0031] The wheel body 43 has an arc-shaped chamfer on the front, which can better fit the surface of the cable. When the cable is initially passed through, it can be squeezed outwards and kept in close contact by the arc-shaped chamfer.
[0032] In use, this solution uses a motor and belt to drive the pulley 5 to rotate, which in turn drives the base cylinder 21 of the rotating frame 2 to rotate. The base cylinder 21 rotates along with the fixed extension 23 and the limiting ear 24 via the pressing part 22. At this time, the rotating disk 3 is limited by the limiting ear 24 and the pressing part 22, keeping the rotating disk 3 rotating within it. At the same time, the pressing part 22 pushes the pressure roller assembly 4 to move together with the protection, so that the rotating disk 3 also rotates synchronously. Furthermore, the arc-shaped design of the pressing part 22 provides clamping force to the cable by pressing the pressure roller assembly 4 along the axial direction, and rotates with the whole, and the rotation is consistent with the direction of the cable stranding helix, so that the extrusion process continues to press along the stranding direction, maintaining the tightness of the stranding. As the wheel body 43 wears down over time, the arc-shaped design of the pressing part 22 maintains pressure on the wheel seat 41, ensuring that the wheel body 43 is always pressed against the cable surface, thus avoiding pressure reduction caused by wear. Furthermore, the wheel body 43 can be replaced by disassembling the mounting part 44. The overall structure is stable and reliable, ensuring stable stranding production.
[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
