[0002] In the current production process of enameled wire, in addition to the felt method for coating, liquid alkane oil can also be used as a lubricant. This type of oil itself has very good lubricity, which prevents the appearance of unevenness on the surface of the enameled wire. It is not easy to evaporate and is completely harmless to the human body.

[0003] For example, a Chinese patent application with application number 201410441310.7 discloses a method for oiling an enameled wire, comprising the following steps: preparing lubricating oil, using liquid alkane oil as the lubricating oil, and an oil pump delivers the lubricating oil in the oil storage tank to the oil tank through a liquid flow pipe; heating the lubricating oil, starting the heating plate at the bottom of the oil tank, and a temperature control device controls the heating plate to heat the lubricating oil and control the oil temperature; oiling the enameled wire, immersing the lower part of a roller in the lubricating oil, and the lower part of the roller presses the enameled wire so that the enameled wire is attached to the outer periphery of the lower end of the roller, and a motor drives the roller to rotate, and the enameled wire moves radially under the roller to complete the oiling; degreasing the enameled wire, using cowhide to scrape off excess lubricating oil on the surface of the enameled wire, so that the lubricating oil is evenly attached to the surface of the enameled wire to complete the coating.

[0033] The following is combined with Figure 1-2 This application is described in further detail.

[0034] The present application embodiment discloses an ultra-fine enameled wire oiling device. Figure 1 and Figure 2 The ultra-fine enameled wire oiling device includes an oil storage tank 1 and an oiling roller 2. The top of the oil storage tank 1 is provided with an opening. The top of the oil storage tank 1 is provided with wire wheels 3 on both sides relative to the outside. The oiling roller 2 is rotatably assembled in the oil storage tank 1. The oiling roller 2 is used to press the enameled wire into the lubricating liquid in the oil storage tank 1 and rub and convey the enameled wire. The bottom of the oil storage tank 1 is provided with an electric heating plate 4. The inner wall of the oil storage tank 1 is provided with a cold air blowing unit 5. The cold air blowing is connected to a cold air supply component 6. The cold air blowing unit 5 is used to blow cold air to the surface of the oiled enameled wire.

[0035] The beneficial technical effects of the ultra-fine enameled wire oiling device of the embodiment of the present application are roughly as follows:

[0036] After the enameled wire is coated with the overheated lubricating oil, the cold air supply component 6 and the cold air blowing unit 5 are started to cool the lubricating oil on the surface of the enameled wire, so as to quickly reduce the temperature of the lubricating oil on the surface of the enameled wire, thereby increasing the viscosity of the lubricating oil. Therefore, during the subsequent transportation of the enameled wire, the lubricating oil is not easy to flow downward due to gravity, which effectively makes the lubricating oil on the surface of the enameled wire more uniform and the oiling effect is better.

[0037] In this embodiment, there are 2-5 groups of cold air blowing units 5 (preferably, there are two groups of cold air blowing units 5), and adjacent cold air blowing units 5 are arranged at intervals, and multiple groups of cold air blowing units 5 are arranged obliquely along the conveying direction of the enameled wire. By providing multiple groups of cold air blowing units 5, the purpose of quickly reducing the temperature of the lubricating oil on the surface of the enameled wire is achieved, and the cooling effect is better.

[0038] In this embodiment, the cold air blowing unit 5 includes a mounting bracket 51, a circular tube 52 and a plurality of branch pipe heads 53. The enameled wire passes through the circular tube 52. The circular tube 52 is fixed to the inner wall of the oil storage tank 1 through the mounting bracket 51. The branch pipe heads 53 are connected to the inner side of the circular tube 52 and are arranged evenly spaced. The circular tube 52 is used to connect to the cold air supply component 6, wherein the number of the branch pipe heads 53 is between 15 and 25, and the air outlet ends of the branch pipe heads 53 are all arranged toward the center of the circular tube 52.

[0039] In order to facilitate the staff to quickly insert the enameled wire into the annular tube 52 in the early stage, a notch 521 is set on one side of the annular tube 52, and the notch 521 is used for the enameled wire to enter and exit, wherein the notch 521 and the mounting bracket 51 are respectively located on opposite sides of the annular tube 52.

[0040] In order to facilitate reliable and stable connection between the annular tube 52 and the cold air supply assembly 6, an air intake connecting pipe 522 is provided on one side of the annular tube 52 close to the mounting bracket 51, and the air intake connecting pipe 522 and the cold air supply assembly 6 are detachable and assembled.

[0041] The cold air blowing unit 5 designed above has a simple structure, is easy to manufacture, has a relatively low production and customization cost, is easy to install, and can blow cold air toward the surface of the enameled wire from multiple angles, resulting in better cooling effect and more uniform cooling.

[0042] In this embodiment, the cold air supply assembly 6 includes a cold air blower 61 and a cold air delivery pipe 62. The cold air delivery pipe 62 is connected between the cold air blowing unit 5 and the cold air blower 61. The cold air delivery pipe 62 is an elastic hose wrapped with thermal insulation cotton.

[0043] The cold air supply assembly 6 of the above design has stable operation and convenient operation, and the cold air delivery pipe 62 has a good thermal insulation effect, which effectively prevents the cold air from being heated during the delivery process. The elastic cold air delivery pipe 62 is easier to bend and install, and has a longer service life.

[0044] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the application should be included in the protection scope of the present application.
