Description

A flexible guide wheel structure for a cable straightening machine Technical Field

[0001] This utility model relates to the field of cable processing equipment technology, and in particular to a flexible guide wheel structure for a cable straightening machine. Background Technology

[0002] Cable straightening is a crucial step in cable production and processing, directly impacting cable performance and lifespan. Cable straightening refers to the process of restoring cables that have been bent or deformed due to improper transportation, storage, or construction to a straight state. Cable straightening technology involves materials science, mechanical engineering, and electrical engineering, and its core lies in restoring the cable's geometry through physical or mechanical means while avoiding damage to its internal structure and insulation properties.

[0003] However, traditional cable straightening machines use rigid guide rollers. This rigid roller structure easily scratches the cable surface during straightening, affecting the cable's appearance and potentially damaging the insulation layer, thus reducing its electrical performance. Furthermore, due to differences in the curvature and stiffness of different cables, rigid guide rollers cannot guarantee uniform and effective straightening for all types of cables, resulting in unsatisfactory straightening effects and a high scrap rate. Therefore, developing a flexible guide roller structure is of significant practical importance.

[0004] For example, direct contact between metal guide rollers and cables can easily lead to localized stress concentration, causing scratches or micro-cracks in the insulation layer of high-voltage cables and reducing their withstand voltage level. At the same time, if metal debris, sludge, or other contaminants are attached to the cable surface, these impurities can cause secondary scratches during the straightening process under the pressure of the rigid guide roller structure. Furthermore, foreign objects stuck in the gap between the guide rollers can cause equipment failure. Summary of the Invention

[0005] This utility model discloses a flexible guide wheel structure for a cable straightening machine, which aims to solve the technical problem that the cable surface is easily scratched during the cable straightening process, affecting the appearance quality of the cable, and may even damage the insulation layer of the cable and reduce the electrical performance of the cable.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A flexible guide wheel structure for a cable straightening machine includes a straightening machine body, a cable frame, and a guide wheel support arm. It further includes: a cleaning mechanism: the cleaning mechanism includes a first adjusting device disposed on the bottom outer wall of the guide wheel support frame, and a second adjusting device disposed on the outer outer wall of the guide wheel support frame. A guide wheel body is connected to the guide wheel support frame, the first adjusting device, and the second adjusting device. The guide wheel body has micro-holes on its surface, and these micro-holes are pneumatically connected to the straightening machine body. A flexible protection mechanism is disposed on the guide wheel body.

[0008] In this solution, the cleaning mechanism can blow away oil, metal debris, and other impurities from the cable surface through the micro-holes on the guide wheel surface. In actual use, appropriate parameters are set through the first and second adjustment devices. After the cable enters the straightening system of the straightening machine, the straightening machine body precisely controls the air jet frequency and air pressure of the micro-holes on the guide wheel surface through the proportional valve, which can self-clean impurities on the cable surface, avoid damage to the cable surface insulation layer and affect the straightening accuracy during the straightening process. The structure is simple and easy to use.

[0009] In a preferred embodiment, the flexible protection mechanism includes a flexible layer disposed on the outer wall of the guide wheel body, a steel wheel base layer disposed inside the guide wheel body, the flexible layer covering the outer surface of the guide wheel body, and the flexible layer being composed of a polyurethane layer and a gradient foaming layer.

[0010] By using the flexible contact of the guide wheel surface to reduce the hard friction of the wire insulation layer, and combined with the anti-slip micro-texture to increase traction and prevent slippage, "zero damage" straightening is achieved.

[0011] In a preferred embodiment, an inlet guide sleeve is provided at one end of the guide wheel support arm near the cable rack, an inlet hole sleeve is connected to the inlet guide sleeve, and a cleaning brush is provided on the inner wall of the inlet hole sleeve.

[0012] The cable straightener integrates a cleaning brush into the inlet sleeve. The brush bristles remove dust, impurities, and attachments from the cable surface, achieving multiple benefits. It effectively prevents foreign objects such as mud and sand from entering the guide roller assembly, avoiding wear on precision components and scratches on the insulation layer. At the same time, it improves the uniformity of straightening pressure and significantly enhances the compatibility with cables in complex environments. Balancing safety and cleaning efficiency, it further realizes the technological upgrade from passive protection to active optimization, becoming a key innovation for improving the stability of the straightener and the quality of the cable.

[0013] As described above, a flexible guide wheel structure for a cable straightening machine includes a straightening machine body, a cable frame, and a guide wheel support arm. It also includes: a cleaning mechanism: the cleaning mechanism includes a first adjusting device disposed on the bottom outer wall of the guide wheel support frame, and a second adjusting device disposed on the outer outer wall of the guide wheel support frame.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] The flexible guide wheel structure of the cable straightening machine disclosed in this utility model is mainly used in scenarios where traditional rigid guide wheels cause scratches on the cable surface during the straightening process, affecting the appearance quality of the cable, damaging the insulation layer of the cable, and reducing the electrical performance of the cable.

[0022] Referring to Figures 1 and 2, a flexible guide wheel structure for a cable straightening machine includes a straightening machine body 1, a cable frame 2, and a guide wheel support arm 3. It also includes: a cleaning mechanism: the cleaning mechanism includes a first adjusting device 5 disposed on the bottom outer wall of the guide wheel support frame, and a second adjusting device 6 disposed on the outer side wall of the guide wheel support frame. A guide wheel body 4 is connected to the guide wheel support frame, the first adjusting device 5, and the second adjusting device 6. The guide wheel body 4 has micro-holes 10 on its surface, and these micro-holes 10 are pneumatically connected to the straightening machine body 1; and a flexible protection mechanism: the flexible protection mechanism is disposed on the guide wheel body 4.

[0023] In practical use, after setting appropriate parameters through the first adjustment device 5 and the second adjustment device 6, once the cable enters the straightening system of the straightening machine, the straightening machine body 1 precisely controls the air jet frequency and air pressure of the micro-holes 10 on the surface of the guide wheel through the proportional valve. This can self-clean impurities on the cable surface, avoid damage to the cable surface insulation layer and affect the straightening accuracy during the straightening process. The structure is simple and easy to use.

[0024] Referring to Figures 1 and 4, in a preferred embodiment, the flexible protection mechanism includes a flexible layer 7 disposed on the outer wall of the guide wheel body 4 and a steel wheel base layer 9 disposed inside the guide wheel body 4. The flexible contact of the guide wheel surface reduces the hard friction of the wire insulation layer, and the anti-slip micro-texture increases the traction force to prevent slippage and achieve "zero damage" straightening.

[0025] The flexible layer 7 covers the outer surface of the guide wheel body 4. The flexible layer 7 can be made of materials with high elasticity, wear resistance and low coefficient of friction, such as rubber and polyurethane, to provide flexible support and straightening force for the cable. The steel wheel base layer 9 can be made of high-strength and wear-resistant alloy materials to ensure the durability and stability of the guide wheel.

[0026] A pressure sensor 8 is installed at the connection between the flexible layer 7 and the steel rotating base layer 9. The pressure sensor 8 provides real-time data feedback, and the pneumatic system adjusts the pressure to the optimal value to achieve dynamic pressure regulation. Closed-loop pressure regulation ensures consistent straightening quality and realizes intelligent control.

[0027] Referring to Figures 1 and 3, in a preferred embodiment, an inlet guide sleeve plate 11 is provided at one end of the guide wheel support arm 3 near the cable rack 2, an inlet hole sleeve 12 is connected to the inlet guide sleeve plate 11, and a cleaning brush 13 is provided on the inner wall of the inlet hole sleeve 12.

[0028] Specifically, a cleaning brush 13 is integrated into the inlet sleeve 12 of the cable straightening machine. The brush bristles remove dust, impurities, and attachments from the cable surface, achieving multiple benefits. It effectively prevents foreign objects such as mud and sand from entering the guide roller assembly, avoiding wear on precision components and scratches on the insulation layer. At the same time, it improves the uniformity of straightening pressure and significantly enhances the compatibility with cables in complex environments. It balances safety and cleaning efficiency, further realizing a technological upgrade from passive protection to active optimization, becoming a key innovation to improve the stability of the straightening machine and the quality of the cable.

[0029] The cleaning brush 13 is made of soft materials such as nylon or horsehair. The cleaning brush 13 is electrically connected to the straightening machine body 1. The soft material can avoid scratching the cable. At the same time, the electrically connected adjustable brush bristle contact pressure can adapt to different specifications of cables.

[0030] Referring to Figures 1 and 3, in a preferred embodiment, the guide wheel support arm 3 is connected to the first adjusting device 5 and the second adjusting device 6 by bolts and nuts.

[0031] Specifically, by adjusting the position or tightness of fasteners such as bolts and nuts, the position or angle of the guide wheel body 4 can be finely adjusted, which can adapt to the straightening requirements of cables of different specifications and materials, improve the straightening accuracy and effect, and further improve the adaptability and straightening accuracy of the flexible guide wheel.

[0032] Working principle: During use, the cable is led out from the cable rack 2, passes through the inlet hole sleeve 12 of the inlet guide sleeve plate 11, and the cleaning brush 13 on the inner wall of the inlet hole sleeve 12 removes dust and other impurities from the cable surface. Then, after the cable enters the straightening system, the parameters are set by the first adjustment device 5 and the second adjustment device 6. The straightening machine body 1 precisely controls the air jet frequency and air pressure of the micro-holes 10 on the surface of the guide wheel through the proportional valve, which self-cleans the impurities on the cable surface and avoids damage to the insulation layer and affecting the straightening accuracy. During the straightening process, the flexible layer 7 outside the guide wheel body 4 makes flexible contact with the cable to reduce hard friction. The anti-slip micro-texture increases the traction force and prevents slippage. The steel wheel base layer 9 ensures the durability and stability of the guide wheel. The pressure sensor 8 at the connection between the two provides real-time feedback data. The pneumatic system adjusts the pressure to the optimal value accordingly to achieve dynamic pressure adjustment and consistency of straightening quality.

[0033] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
