After being coated for the first time, they are evenly powder coated for the first time by the first cleaning brush to make the coating more uniform. At the same time, with the cooperation of the first return spring 17, wires and cables of different sizes can be powder coated.

[0026] The inner side of the first rotating tube 10 and the second rotating tube 11 is provided with a spraying assembly for applying the surface layer of the insulating sheath of the wire and cable, and the spraying assembly includes a powder storage box 12 fixedly mounted on the top of the inner circumferential surface of the first rotating tube 10 and the second rotating tube 11, and the outer bottom of the powder storage box 12 and the inner circumferential surface bottom of the first rotating tube 10 and the second rotating tube 11 are evenly spaced and installed with a nozzle 13, and the powder storage box 12 and the nozzle 13 are mutually connected through a connecting pipe 14, and then the outer top of the powder storage box 12 is connected with a powder inlet pipe 15, and one end of the powder inlet pipe 15 extends to the outer circumferential surface of the first rotating tube 10 and the second rotating tube 11, respectively, and a valve is fixedly mounted on the outer circumferential surface of the powder inlet pipe 15.

[0031] At the same time, when the first rotating tube 10 and the second rotating tube 11 rotate, the talcum powder is transported to the circulation pipe through the powder suction machine arranged on the outer side of the powder storage box 12, and the wires and cables are subjected to double all-round circulation spraying through the nozzle 13, so that the sliding powder can be evenly applied to the outer surface of the wires and cables, thereby improving the uniform spraying effect.
