in the blowing process, the air guide shaft (6) drives the stirring rotating shaft (7) to rotate, and the stirring rotating shaft (7) and the stirring plate (9) stir the paint in the material storage cavity (2) so as to keep the paint uniform;
s4, inputting the air in the air blowing cavity (3) into the air injection pipe (403) through the first hose (12) by the blast pipe (11), and rapidly injecting the air into the guide pipe (405) by the air injection pipe (403);
s5, along with the air jet pipe (403) jetting air rapidly, negative pressure is generated in the negative pressure box (402), and the paint in the storage cavity (2) enters the negative pressure box (402) along the material conveying pipe (13), the second hose (14) and the material discharging pipe (404);
s6, the air and the coating are conveyed into the mixing pipe (406) by the guide pipe (405), the coating carried by the air is sprayed out through the diffuser pipe (407), and the coating is uniformly sprayed out through spray holes uniformly distributed on the grid disc (408); in the spraying process, the air pressure in the material storage cavity (2) is increased through the pressurizing assembly (20), so that the high-pressure state is kept above the liquid level in the material storage cavity (2), and the output of the coating is facilitated;
s7, after the spraying is finished, closing a control valve on the material conveying pipe (13), heating air output from the air supply box (19) through the electric heating pipe (25), enabling the heated air to enter the air blowing cavity (3), and finally blowing hot air out through the diffuser pipe (407) so as to rapidly dry the coating at the spraying position and improve the spraying efficiency.
