[0002] Conductive materials (such as metal wires and cables) are widely used in electrical equipment and systems. To ensure the reliability and safety of these materials in practical use, their electrical properties (such as resistance, voltage, and current) must be monitored in real time during production or processing. This monitoring typically requires the material to be in motion to simulate the operating conditions encountered in actual applications.

This method is not only time-consuming but also fails to reflect the material's performance in a dynamic operating environment, potentially leading to substandard products entering the market.

[0019] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to further illustrate the present invention.

[0020] First, combine Figures 1 and 2 The conductive wheel mechanism for metal wire detection according to an embodiment of the present invention is described. The conductive wheel mechanism is used for metal wire detection and has a wide range of application scenarios.

[0021] like Figures 1 and 2 As shown, the conductive wheel mechanism for metal wire detection according to an embodiment of the present invention comprises: a conductive wheel 1 , a conductive shaft 2 , a conductive slip ring 3 and a bracket 4 .

[0022] Specifically, if Figures 1 and 2 As shown, in this embodiment, the conductive wheel 1 is fixed on the conductive shaft 2; one end of the conductive shaft 2 is connected to the conductive slip ring 3 through a connector 5; a bracket 4 is provided at the bottom of the conductive shaft 2 to support and fix the conductive shaft 2; the conductive wheel 1 transmits the signal to the conductive slip ring 3 through the conductive shaft 2. Due to the close combination of the conductive wheel 1, the conductive shaft 2 and the conductive slip ring 3, signal transmission can achieve lossless conduction during high and medium speed operation. The signal is directly transmitted from the conductive wheel 1 to the conductive slip ring 3 through the conductive shaft 2, which reduces the complexity of the signal path and ensures efficient and low-latency signal transmission. It is particularly suitable for application scenarios requiring real-time detection.

[0023] Further, if Figures 1 and 2 As shown, in this embodiment, the conductive wheel 1 and the conductive shaft 2 are made of copper, which has high conductivity, corrosion resistance, wear resistance and high temperature stability.

[0024] Further, if Figures 1 and 2 As shown, in this embodiment, the bracket 4 is an insulating bracket 4, which ensures good electrical isolation between the conductive shaft 2 and other non-conductive parts. The conductive shaft 2 passes through the bracket 4 and is rotatably connected to the bracket 4. The bracket 4 provides stable mechanical support.

[0025] Further, if Figures 1 and 2 As shown, in this embodiment, the conductive wheel 1 is provided with a first inner tapered hole, and the conductive shaft 2 is provided with a tapered surface at the junction with the conductive wheel 1. The tapered surface cooperates with the first inner tapered hole to secure the conductive wheel 1. The cooperation between the tapered surface and the first inner tapered hole provides a self-positioning function. During assembly, the tapered structure automatically adjusts the relative position of the conductive wheel 1 and the conductive shaft 2, thereby ensuring the precise positioning of the conductive wheel 1 on the shaft. The tapered surface cooperation provides a stronger connection strength than a flat connection. The larger contact area of ​​the tapered cooperation can more evenly distribute the load, reduce stress concentration, and thus improve the connection strength between the conductive wheel 1 and the conductive shaft 2. Even when rotating at high speeds or under high torque, the conductive wheel 1 can be firmly fixed to the conductive shaft 2. During rotation, the slope of the tapered surface produces a self-locking effect, preventing the conductive wheel 1 from sliding or loosening along the axial direction of the conductive shaft 2.

[0026] Further, if Figures 1 and 2 As shown, in this embodiment, the conductive wheel 1 is fixed to the conductive shaft 2 by screws, which is stable and reliable and easy to install and disassemble.

[0027] Specifically, if Figures 1 and 2 As shown, in this embodiment, the connector 5 is a nut or an annular buckle. One end of the conductive shaft 2 is provided with a slot 21 and a second inner tapered hole 22 along its length. The outer wall of the second inner tapered hole 22 is provided with an external thread 23. The conductive slip ring 3 is conventional. The outer wall of the rotating shaft 31 of the conductive slip ring 3 is provided with a first outer tapered surface, which mates with the second inner tapered hole 22. The nut mates with the external thread 23. If the connector 5 is a nut, the nut is threaded onto the outer wall of the second inner tapered hole 22 to secure the conductive shaft 2 to the conductive slip ring 3. If the connector 5 is an annular buckle, the annular buckle directly clamps and secures the conductive shaft 2 and the conductive slip ring 3. The fit between the first outer tapered surface and the second inner tapered hole 22 provides precise centering. The connector 5 achieves a strong connection and strong adaptability, achieving an integrated state between the rotating shaft of the conductive slip ring 3 and the conductive shaft 2.

[0028] Working principle: The metal wire is connected to two sets of conductive wheels 1. The external traction machine drives the metal wire to move. The movement of the metal wire drives the conductive wheel 1 to rotate, thereby driving the rotation of the conductive shaft 2 and the conductive slip ring 3. During the rotation process, the conductive wheel 1 transmits the signal to the conductive slip ring 3. During detection, the external resistance meter can detect the resistance value on the metal wire between the two sets of conductive wheels 1 through the conductive slip ring 3 (generally calculated based on the resistance value of one meter long). It can also detect the voltage and current on the metal wire between the two sets of conductive wheels 1.

[0029] Above, refer to Figures 1 and 2 The conductive wheel mechanism for metal wire detection according to the embodiment of the utility model is described. It can achieve stable conductivity during high and medium speed operation, and has the characteristics of simple structure, easy installation and maintenance, so as to meet the demand for real-time electrical characteristics detection in the production process of conductive materials. It can not only improve production efficiency, but also effectively ensure product quality, providing reliable technical guarantee for the widespread application of conductive materials.
