[0043] When the fully automatic spraying device is needed, the user can first assemble the overall structure as shown in the figure, and then rotate it as needed before use. Figure 1 or Figure 2 In the downward spraying or horizontal spraying state shown, after installation, an external air pump injects air into the air inlet pipe 5 through a pressure regulating valve, so that the air pressure inside the oil pot 1 is at a certain pressure, and then the paint inside is output stably at a certain pressure, and is transported to the automatic spray gun 3 through the oil discharge pipe 17 and the oil outlet pipe 2, so that the automatic spray gun 3 sprays the paint on the workpiece. In addition, in this case, since the main structure of the oil pot 1 adopts a split oil pot cover 16, an oil pot body 14 and a disposable paper cup 13 as a paint carrier, in the specific use process, only manual or automatic control is required. By opening and closing the fastening device 6, the oil pot main body 14 and the disposable paper cup 13 serving as the paint carrier can be removed and the disposable paper cup 13 can be replaced. In addition, since the disposable paper cup 13 is used as the paint carrier structure, there is almost no paint residue inside the oil pot during use, thereby achieving the purpose of quickly replacing the paint and eliminating the need to clean the oil pot. At the same time, since the structural design in this case is relatively concise, the paint replacement process is achieved by only using structures such as buckling and overlapping, making this case easier to be integrated with automated equipment to achieve the purpose of automatic material replacement and fully automatic spraying.
