The extrusion coating machine is provided with a wire inlet hole and a wire outlet hole. When in use, the wire core to be coated with the insulation layer passes through the extrusion coating machine and the extrusion coating is applied. The coating machine coats the molten plastic on the outside of the wire core, and then blows cold air to the outside of the wire core through a cooling fan, so that the plastic on the outer wall of the wire core is cooled and an insulating layer is formed on the outer wall of the wire core; the inventor believes that there are the following problems during use. After the wire core comes out of the extrusion coating machine, the temperature of the insulating layer on its outer wall is still relatively high and still has a certain viscosity, and the cooling fan blows air directly onto the insulating layer of the wire core, which easily causes dust in the air to adhere to the surface of the insulating layer of the wire core, resulting in an uneven surface of the wire core, affecting later use.
