[0005] To achieve the above object, the utility model adopts the following technical solutions: A coating mechanism for enameled wire lubricant of the utility model includes a lubricant tank. A transverse partition is provided inside the lubricant tank, which divides the inner part of the lubricant tank body into a felt installation chamber and a lubricant chamber. A communication hole is provided on the transverse partition to connect the felt installation chamber and the lubricant chamber. Along the movement direction of the wire body in the felt installation chamber, an upper and lower felt assembly and a front and rear felt assembly are respectively provided. On both side chamber walls of the felt installation chamber along the movement direction of the wire body, an inlet and an outlet for the wire body to pass through are provided. An oil overflow port is also provided on the chamber wall of the felt installation chamber, and an oil inlet is provided on the chamber wall of the lubricant chamber. In the utility model, the lubricant is transported into the lubricant chamber through the oil inlet, enters the felt installation chamber through the communication hole, and continuously infiltrates the felts in the upper and lower felt assembly and the front and rear felt assembly to ensure the coating amount. The wire body enters through the inlet and exits through the outlet. Among them, the upper and lower felt assembly clamps the wire longitudinally up and down (Z direction), and the front and rear felt assembly clamps the wire horizontally front and back (Y direction). When the wire body passes through the upper and lower felt assembly and the left and right felt assembly, the felt can completely surround the wire body 360°, there is no coating dead angle, and the lubricant is evenly coated.

[0006] Preferably, the upper and lower felt assembly includes an upper felt and a lower felt arranged opposite to each other up and down. The upper felt and the lower felt are respectively fixedly connected to the upper chamber wall and the lower chamber wall of the felt installation chamber.

[0007] Preferably, the front and rear felt assembly includes a front felt and a rear felt arranged opposite to each other front and back. The front felt and the rear felt are respectively fixedly connected to the front chamber wall and the rear chamber wall of the felt installation chamber.

[0008] Preferably, the coating mechanism for enameled wire lubricant further includes a high-level lubricant box and a low-level lubricant box. The high-level lubricant box is higher than the lubricant tank and is connected to the oil inlet through a pipeline; the low-level lubricant box is lower than the lubricant tank and is connected to the oil overflow port through a pipeline. By setting the high-level lubricant box and the low-level lubricant box, the automatic replenishment of the lubricant in the lubricant chamber is realized by using the height difference, and at the same time, the automatic discharge of the lubricant in the felt installation chamber is realized, and the circulating flow of the lubricant is realized, ensuring the stability and uniformity of the siphon effect of the felt on the lubricant.

[0009] Preferably, a liquid flow meter is connected to the pipeline between the low-level lubricant box and the lubricant tank.

[0010] Preferably, a constant temperature heating plate is provided at the bottom of the lubricant tank. The constant temperature heating plate conducts constant temperature heating management on the lubricant tank, keeps the temperature of the lubricant in the lubricant tank constant, and further ensures the stability of the viscosity to ensure the stability of the coating amount.

[0011] Therefore, the utility model has the following beneficial effects:

[0012] (1) The lubricant in the lubricant chamber can enter the felt installation chamber through the communication holes to continuously soak the felts in the upper and lower felt assemblies and the front and rear felt assemblies, ensuring the coating amount.

[0013] (2) The upper and lower felt assemblies and the front and rear felt assemblies are provided in the felt installation chamber. When the wire body passes through the upper and lower felt assemblies and the left and right felt assemblies, the felt can completely surround the wire body 360°, there is no coating dead angle, and the lubricant is evenly coated. 9 Description of the Drawings
