[0029] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0030] When in use, the user places the electrical cabinet to be sprayed onto the conveying assembly 2 through the rear inclined plate and the curtain of the frame 1, and conveys the electrical cabinet to the middle of the auxiliary spray-molded part 6 through the conveying assembly 2. The positions of the two sets of auxiliary spray-molded strips are adjusted through the auxiliary motor and the auxiliary screw, so that the distance between the two sets of spray-molded strips is slightly larger than the distance between the front and rear sides of the electrical cabinet. The material extraction pump 41 is turned on, and the material extraction pump 41 extracts external powder and sprays it through the first three-way valve 42, the second three-way valve 44, the second bifurcated pipe 46, and the two sets of auxiliary spray-molded strips.

At this time, the powder is sprayed out through the second three-way valve 44, the telescopic tube, and the vertical spraying strip 45, and is transported to the electrical cabinet through the conveying assembly 2. The top of the electrical cabinet is sprayed when passing through the vertical spraying strip 45. Finally, the second motor 32 and the screw 33 cooperate to make the spraying ends of the two groups of spraying strips 34 close to the left and right sides of the electrical cabinet respectively, so that the first three-way valve 42 is reversed. At this time, the material pump 41 supplies the two groups of spraying strips 34 through the first three-way valve 42 and the first bifurcated pipe 43, so that the two groups of spraying strips 34 spray the left and right sides of the electrical cabinet passed by. In the above-mentioned spraying process, the curtains on the front and rear sides of the frame 1 block the scattered powder to prevent the powder from drifting to the outside of the frame 1.
