Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel wire powder coating technology, and in particular to a device for efficient and uniform coating of steel wire drawing powder. Background Technology
[0002] Wire drawing is a common process in metal processing, which mainly involves drawing a rough steel billet into a thin wire through a series of dies. In order to improve the service life of the steel wire and its performance in specific applications, it is usually necessary to coat its surface before drawing. Coating with drawing powder can effectively improve the wear resistance, corrosion resistance and reduce friction of the steel wire, ensuring its smooth operation in subsequent processing. The steel wire powder coating process helps to achieve more efficient production and more stable product quality.
[0003] In the prior art, such as the "Lubricating Powder Coating Device in the Cold Drawing Process of Metal Wire" of Chinese Patent CN207204873U, this utility model can easily achieve dense, uniform and comprehensive coating of lubricating powder on the surface of metal wire, effectively solving various quality problems of metal wire in the cold drawing process. Moreover, the tooling is practical and easy to operate, making it an efficient tool in industrial cold drawing production.
[0004] However, in existing technologies, steel wire drawing powder coating devices lack effective temperature control structures, making it impossible to maintain a stable temperature during steel wire conveying. This results in excessively low steel wire surface temperatures, making it difficult for the drawing powder to fully adhere to the steel wire surface and affecting the subsequent adhesion effect of the drawing powder. In addition, the drawing powder may accumulate or clog in the conveying pipeline, making it difficult to ensure uniform distribution of the drawing powder and further reducing coating efficiency. Uneven powder distribution not only affects the effective coating of the drawing powder but also leads to unstable coating quality on the steel wire surface, making it impossible to efficiently and uniformly distribute on the steel wire surface, thus affecting the coating effect of the steel wire and ultimately the quality of the final product. Utility Model Content
[0005] The purpose of this invention is to solve the problems of existing steel wire drawing powder coating devices lacking an effective temperature control structure, failing to maintain a stable temperature during steel wire conveying, resulting in uneven adhesion of drawing powder and affecting the coating effect. In addition, drawing powder may accumulate or clog in the conveying pipeline, leading to uneven powder distribution, which in turn reduces coating efficiency and affects the quality of the coating on the steel wire surface, ultimately affecting product quality. Therefore, this invention proposes a high-efficiency and uniform coating device for steel wire drawing powder.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency and uniform coating device for steel wire drawing powder, comprising a feeding box, a needle electrode, and a discharge pipe. A heat preservation box is fixedly connected to the back of the feeding box, and a powder coating box is fixedly connected to the back of the heat preservation box. The needle electrode is fixedly connected at equal intervals inside the powder coating box. A powder inlet pipe is fixedly connected to the side of the powder coating box. A blower is fixedly connected inside the powder coating box, and the blower is located near the top of the needle electrode. The discharge pipe is fixedly connected to the back of the powder coating box.
[0007] In a preferred embodiment, a feeding roller is rotatably connected inside the feeding box, a motor base is fixedly connected to the side of the feeding box, a power motor is fixedly connected inside the motor base, and the feeding roller is divided into two groups. A power rod is fixedly connected to the inner wall of one group of feeding rollers, and a transmission rod is fixedly connected to the inner wall of the other group of feeding rollers.
[0008] The technical effect of adopting the above-mentioned further solution is that the design of two sets of feed rollers ensures the stability of the steel wire during the conveying process, reduces the wear of individual feed rollers, and extends the overall working life of the device.
[0009] In a preferred embodiment, the power rod and transmission rod are rotatably connected inside the feed box, and the power rod and transmission rod pass through the feed box on the side near the motor base. The power motor is fixedly connected to one end of the power rod that passes through the feed box. A power belt is rotatably connected to the outer wall of the power rod and transmission rod, and the power belt is located near the power motor.
[0010] The technical effect of adopting the above-mentioned further solution is that by connecting the power rod and the transmission rod with a power belt, the power transmission efficiency of the power motor is improved and the use of power sources is reduced.
[0011] In a preferred embodiment, a heating wire is fixedly connected inside the insulation box, and a conveying channel is provided inside the insulation box, with the heating wire wrapped around the box near the conveying channel.
[0012] The technical effect of adopting the above-mentioned further solution is that by placing the heating wire near the conveying channel, the steel wire is kept at a suitable temperature before coating, preventing the subsequent powder coating effect from being affected by the low temperature.
[0013] In a preferred embodiment, a spiral conveying blade is rotatably connected inside the powder inlet pipe, a powder inlet hopper is fixedly connected to the outer wall of the powder inlet pipe, a powder outlet pipe is fixedly connected to one end of the powder inlet pipe near the powder coating box, the powder outlet pipe is fixedly connected inside the powder coating box, and a rotating shaft is fixedly connected to the inner wall of the spiral conveying blade.
[0014] The technical effect of adopting the above-mentioned further solution is that, through the design of the spiral conveyor blade, the drawing powder is effectively and evenly conveyed to the powder outlet pipe, preventing the drawing powder from being blocked or flowing irregularly in the pipe, thereby ensuring the quality of subsequent coating.
[0015] In a preferred embodiment, the rotating shaft is rotatably connected inside the powder inlet pipe, the rotating shaft passes through the end of the powder inlet pipe away from the powder coating box, a transmission belt is rotatably connected to the outer wall of the rotating shaft, and the end of the transmission belt away from the rotating shaft is rotatably connected to the outer wall of the transmission rod.
[0016] The technical effect of adopting the above-mentioned further solution is that by connecting the transmission rod and the rotating shaft with the transmission belt, the power of the power motor is effectively transferred to the screw conveyor blade, thereby improving the overall operating efficiency of the device and reducing unnecessary power sources.
[0017] In a preferred embodiment, the top of the hair dryer is fixedly connected to an air inlet pipe, which is fixedly connected inside the powder coating box. The air inlet pipe passes through the side of the powder coating box away from the powder inlet pipe, and the bottom of the hair dryer is fixedly connected to nozzles at equal intervals.
[0018] The technical effect of adopting the above-mentioned further solution is that by installing air nozzles at equal intervals, the airflow can be evenly distributed in the powder coating box, which helps the wire drawing powder to evenly cover the surface of the steel wire, thereby improving the coating efficiency.
[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0020] When the device needs to transport steel wire, the steel wire is passed through the feed box, the power motor is started, and the power rod is driven to rotate. The power rod drives the transmission rod to rotate through the power belt, thereby rotating the feed roller and winding the steel wire in. The steel wire then passes through the heat preservation box. During this process, the heating wire is energized to heat the steel wire and maintain its temperature, preventing the subsequent powder coating effect from decreasing due to low temperature. This achieves efficient steel wire transport and maintains the steel wire temperature during transport, ensuring the quality of the subsequent powder coating process.
[0021] When the device needs to coat steel wire with powder, the steel wire enters the powder coating box, and the wire drawing powder enters the powder inlet pipe from the powder inlet hopper. The transmission rod drives the rotating shaft to rotate through the transmission belt, which in turn drives the spiral conveyor blade to rotate, stably and evenly conveying the wire drawing powder to the powder outlet pipe. The airflow is sprayed out from the air nozzle through the air inlet pipe, blowing up the conveyed wire drawing powder and distributing it evenly in the powder coating box, realizing the uniform coating of wire drawing powder on the surface of the steel wire. At the same time, the needle electrode is activated to generate an electrostatic field, which enhances the adhesion of the powder, making it easier for the wire drawing powder to adhere to the surface of the steel wire, thereby improving the efficiency and uniformity of the coating effect and reducing powder waste and uneven coating.
