Description

Technical Field

[0001] This utility model relates to the field of powder removal devices for bare copper wire surfaces, and more specifically, to a powder removal device for bare copper wire surfaces. Background Technology

[0002] High-speed enameling machines produce bare copper wires of corresponding specifications through the wire drawing process. At this stage, the surface of the bare copper wire is covered with a large amount of copper powder and drawing oil. After cleaning with RO water, it enters the enameling machine's annealing furnace for annealing, followed by surface coating and then curing in the enameling machine's baking furnace. Finally, it undergoes cooling, winding, and inspection to become the finished enameled wire. Currently, the common method for removing copper powder involves placing two wiping felts in the cleaning water tank before entering the annealing furnace and wiping the surface of the bare copper wire. However, over time, a large amount of copper powder accumulates on the wiping felts, and the aging of the felts leads to a decrease in cleaning effectiveness. As a result, the large amount of copper powder adhering to the surface of the bare copper wire cannot be completely removed, leading to poor performance indicators of the produced enameled wire products (such as appearance, adhesion, coating continuity, and salt water pinholes). This seriously affects the quality of the enameled wire products and the continuity of production, resulting in a decrease in the pass rate and a significant increase in costs. Therefore, we propose a copper powder remover for the surface of bare copper wire.

[0003] In traditional technology, the utility model authorized by CN216095058U discloses a copper powder remover for bare copper wire surfaces, including a base, a cleaning component, and a support component. The base has a cleaning ring fixedly connected to its upper surface center. The upper end of the cleaning ring has an air ring that engages with an annular through-hole at the upper end of the cleaning ring. An air inlet pipe at the top of the air ring connects to an external air source. The cleaning component is located in the middle of the cleaning ring and includes a first motor, a worm gear, a worm wheel ring, and brush strips. The first motor is located at the lower right side of the cleaning ring, and its output shaft passes through the right side wall of the cleaning ring and extends into the interior of the cleaning ring. The support component is symmetrically arranged at the front and rear ends of the upper surface of the base and also includes a control switch group located on the right side of the base. The input end of the control switch group is electrically connected to an external power source. This copper powder remover for bare copper wire surfaces has a high degree of automation and good cleaning effect. In the above-disclosed structure, a single worm gear ring is used to connect the brush strip, and then a blower structure is configured. This structure cannot be installed as a whole, is prone to misalignment and interference, and is not conducive to connecting the copper wire to the inside. It has poor adaptability and cannot perform cleaning at multiple positions and angles, which affects the cleaning effect. It needs to be improved.

[0004] In the prior art, such as the authorized announcement number CN222001304U, this utility model discloses a powder removal device for the surface of bare copper wire, including a fixed base. The upper surface of the fixed base is provided with a connecting groove. An adjusting base is slidably installed inside the connecting groove. A connecting rod is fixedly connected to one end of the adjusting base. An installation ring is fixedly connected to one end of the connecting rod. An avoidance notch is provided on one side of the installation ring. An annular through groove is provided on the other side of the installation ring. A threaded tube is slidably installed inside one end of the annular through groove. A U-shaped frame is fixedly connected to one end of the threaded tube. The U-shaped frame is located at the center of the installation ring. Cleaning brushes are fixedly connected to both sides of the U-shaped frame. The U-shaped frame has a cavity inside, which facilitates the integration of wiping and blowing positions, making it easy to combine and install. It can connect multiple positions for multi-directional wiping, improving the wiping effect, avoiding residue, and is highly efficient and stable, which is conducive to combined use.

[0005] Its blowing structure causes the powder to scatter in all directions, creating a lot of dust. The cleaning brush uses two squeezing and brushing methods to clean the surface of the copper wires, which are covered with copper powder. The squeezing and brushing is not thorough and cannot effectively remove the surface powder. Utility Model Content

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a powder removal device for the surface of bare copper wire. It uses two combined semi-circular tube shell structures with brush strips at the inner end. The copper wire passes through the semi-circular tube shells.

It effectively and completely removes surface powder without generating dust.

[0007] To solve the above problems, the present invention adopts the following technical solution.

By rotating the semi-circular tubes at high speed, the brush strips are driven to adhere to the surface of the copper wires and rotate to remove copper powder. This effectively and thoroughly removes surface powder without generating dust.
