Description
Technical Field
[0001] This utility model relates to the field of enameled wire technology, specifically to an enameling device for enameled wire. Background Technology
[0002] Enameled wire is a type of electrical wire, typically consisting of a metallic wire (such as copper or aluminum) as the conductor, coated with an insulating varnish. This varnish is usually a polyamide or polyimide resin, possessing excellent insulation properties and abrasion resistance. Enameled wire is mainly used in electrical equipment such as motors, electromagnetic coils, and transformers as an insulated conductor. The insulating varnish of enameled wire can continue to function at high temperatures, protecting the conductor, reducing current loss, and preventing short circuits. During the manufacturing process, the wire needs to be coated with varnish.
[0003] However, existing wire coating methods have the following problems: they are mainly divided into immersion coating and brush coating. The former involves immersing the wire in varnish to fully wet its surface, then removing and drying it to form enameled wire. However, in actual use, it is difficult to control the thickness of the varnish on the wire surface, and paint residue is prone to appear on the wire. The latter involves using a brush or spray gun to evenly coat the wire surface with varnish, ensuring a uniform varnish layer thickness, and then drying it to form enameled wire. However, this method sometimes has blind spots in the spraying process, and the spraying method can easily lead to heavy pollution of the working environment. Therefore, it is necessary to design corresponding technical solutions to address the existing technical problems. Utility Model Content
[0004] The purpose of this utility model is to provide a device for painting enameled wire, which solves the problems of two main methods: immersion painting and brush painting. The former involves immersing the wire in varnish to fully wet the surface of the wire, then removing and drying it to form enameled wire. However, in actual use, it is difficult to control the thickness of the varnish on the wire surface, and paint residue is easily left on the wire. The latter involves using a brush or spray gun to evenly apply varnish to the surface of the wire to ensure uniform varnish thickness, and then drying it to form enameled wire. However, this method sometimes has blind spots in the painting process, and the painting method can easily lead to heavy pollution of the working environment.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a coating device for enameled wire, comprising a mounting frame, a winding device, a coating box, a drying assembly, and a wind-cooling assembly.

[0018] 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.
[0019] Please see Figure 1-4This utility model provides a technical solution: a coating device for enameled wire, including a mounting frame 1, a winding device, a coating box, a drying assembly, and a wind-cooling assembly. Two sets of winding devices are symmetrically mounted on the mounting frame 1. Each winding device includes a drive motor 2 and a winding roller 3 mounted on the power output end of the drive motor 2. The coating box is mounted on the mounting frame 1 and located between the two sets of winding rollers 3. The coating box includes a paint storage container 4, a pump body 5, a delivery pipe 6, a box body 7, and guide wheels 8. The paint storage container 4 is mounted on the back of the mounting frame 1 and connected to the pump body 5 on one side. The outlet end of the pump body 5 is connected to the box body 7 via the delivery pipe 6. The housing 7 is mounted on the mounting bracket 1. Two sets of guide wheels 8 are symmetrically installed inside the housing 7. The housing 7 is also equipped with lead wire holes 9 on both sides. The drying component is located on the right side of the housing 7 and includes a trimming tube 10, a metal tube 11, an electric heating coil 12 and a distribution box 13. The trimming tube 10 is threaded into the left end of the metal tube 11. The electric heating coil 12 is spirally embedded in the metal tube 11 and connected to the distribution box 13 through a line. The air cooling component is located on the right side of the drying component and includes a blower 14 and an air collection hood 15 installed at the air outlet of the blower 14. The air collection hood 15 is connected to an air cooling pipe 16 through a pipe.
[0020] Further improvements, such as Figure 2 As shown, the interior of the housing 7 is filled with paint. The paint level is higher than the height of the guide wheel 8 but lower than the height of the lead hole 9, which facilitates the painting of the wire.
[0021] Further improvements, such as Figure 3 As shown, the trimming tube 10 has a funnel-shaped structure with a diameter at the left end larger than that at the right end. The inner diameter at the right end of the trimming tube 10 is equal to the inner diameter of the metal tube 11. By designing the inner diameter at the right end of the trimming tube 10 to be the diameter of the required enameled wire, excess wire on the surface can be stripped off when the enameled wire is introduced after the enameled wire has been coated.
[0022] Further improvements, such as Figure 4 As shown, the air-cooled pipe 16 includes a pipe body 17 and an air guide ring 18 installed at the right end of the pipe body 17. Several sets of drainage pipes are evenly installed on the air guide ring 18. The several sets of drainage pipes are distributed in a ring shape, which facilitates uniform and rapid heat dissipation and cooling of the enameled wire.
[0023] Specifically, the drainage tube includes a hollow tube 19 and several sets of air outlet nozzles 20 installed on the hollow tube 19. The air outlet ends of the several sets of air outlet nozzles 20 face the inside of the tube body 17. The airflow is introduced into the air outlet nozzles 20 through the hollow tube 19, and the dried enameled wire is rapidly cooled by air through the air outlet nozzles 20.
[0024] In use: The wire is guided into the housing 7 through the lead hole 9 and guided by the guide wheel 8 and immersed in the paint inside the housing 7. After the paint is applied, the wire is led out from another set of lead holes 9 and enters the trimming tube 10. The inner diameter of the right end of the trimming tube 10 is designed to be the diameter of the required enameled wire. When the enameled wire is introduced after the paint is applied, the excess wire on the surface can be stripped. The trimmed enameled wire is introduced into the metal tube 11 and heated by the electric heating coil 12, which transfers the heat to the metal tube 11 to achieve the purpose of rapid drying of the enameled wire. The dried enameled wire is introduced into the air-cooling tube 16 and blown by the blower 14 into the air collection hood 15 and then into the air-cooling tube 16 through the pipe. The airflow is introduced into the air outlet nozzle 20 through the hollow tube 19 and rapidly air-cooled by the air outlet nozzle 20. Finally, it is wound up by the winding device.
