DETAILED DESCRIPTION

[0020] The utility model is now described in further detail in conjunction with the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0021] Please refer to Figure 1-6 A paint baking device based on enameled wire comprises a baking box 1, wherein a first baking tube 2 and a second baking tube 3 are arranged in the baking box 1, and a paint wrapping tube 4 is arranged between the first baking tube 2 and the second baking tube 3, and the enameled wire 5 passes through the first baking tube 2, the paint wrapping tube 4 and the second baking tube 3 in the baking box 1 in sequence; during use, the enameled wire coated with paint for the first time is firstly baked through the first baking tube 2 to make the paint surface dry and solidify, at this time, the paint surface after the first baking is prone to problems such as pinholes and bubbles, which affect the continuity of the paint film, at this time, it is then coated with paint for the second time through the paint wrapping tube 4, the secondary coating of paint can cover the pinholes and bubbles, so that the paint film is continuous and complete, and then enters the second baking tube 3 for secondary baking, so as to improve the quality of the paint film of the enameled wire; in addition, an enameled wire paint surface grinding mechanism is provided at the output end of the baking box 1, and the paint surface is prone to uneven paint film and inconsistent thickness after the secondary baking, so the uneven parts are polished by the paint surface grinding mechanism to ensure that the paint film is uniform and complete, thereby improving the overall quality.

[0022] Specifically, a first electric heating wire 21 is provided on the outer circumference of the first baking tube 2, and a second electric heating wire 31 is provided on the inner circumference of the second baking tube 3. The temperature inside the second baking tube 3 is higher than that of the first baking tube 2. When in use, the enameled wire 5 is first baked by the first baking tube 2, and the outer layer solvent evaporates. After evaporation, pinholes or bubbles appear in the paint film, and then the pinholes and bubbles are filled with paint, and then the wire is baked again by the second baking tube 3. The baking temperature of the second baking tube 3 is high, and the paint surface is baked and solidified. Then, the uneven paint film and some pinholes or bubbles are polished by an external paint surface polishing mechanism to make the paint film of the enameled wire uniform and complete.

[0023] The paint cylinder 4 is provided with through holes at both ends, and the inner diameter of the through holes is consistent with the outer diameter of the enameled wire to prevent the internal paint liquid from flowing out. The enameled wire 5 passes through the paint cylinder 4 at the through holes. The paint cylinder 4 is fixed to the inner top wall of the baking box 1 through a connecting rod 42. The paint cylinder 4 is provided with a connected paint injection pipe 41, and the paint injection pipe 41 extends upward through the baking box 1. The paint liquid enters the paint cylinder 4 through the paint injection pipe 41. When the enameled wire passes through the paint cylinder 4, the circumference of the enameled wire will be wrapped by the paint liquid again, so that the paint liquid fills the bubbles or pinholes, thereby improving the quality.

[0024] In this embodiment, the paint surface polishing mechanism includes a polishing cylinder 6, a bearing seat 11 is provided at the end of the baking box 1, the polishing cylinder 6 rotates through the bearing seat 11, and the inner wall of the polishing cylinder 6 is provided with polishing sandpaper. When the polishing cylinder 6 rotates, the polishing sandpaper polishes the circumference of the enameled wire 5; thereby removing the raised paint liquid and making the overall surface uniform.

[0025] The paint surface polishing mechanism further includes a motor 63, a driving gear 62 and a driven gear 61. The motor 63 is fixed at the end of the baking box 1. The driving gear 62 is arranged on the output shaft of the motor 63. The driven gear 61 is fixed to the circumference of the polishing cylinder 6. The driven gear 61 is meshed with the driving gear 62. The motor 63 drives the polishing cylinder 6 to rotate through the driving gear 62 and the driven gear 61, thereby realizing paint surface polishing.

[0026] The first baking tube 2, the paint wrapping tube 4, the second baking tube 3 and the polishing tube 6 are all located on the same axis to ensure that the enameled wire 5 passes through in a straight line.

[0027] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
