[0019] The specific workflow is as follows:
[0020] Before adding liquid, open the exhaust valve 121 to exhaust the air in the passage 12 to ensure that the sprayed liquid is not mixed with air and the flow rate of each spray gun is consistent, connect the hose on the diaphragm pump 2 to the liquid inlet 305 on the pressure tank with a clamp, connect the corresponding branch pipe 13 to the corresponding spray gun (not shown in the figure) through the hose, and the corresponding spray gun is set in the corresponding coating pot 11 through the bracket. Close the second manual valve 304 and the first manual valve 303, open the diaphragm pump 2, and transport the liquid in the liquid preparation barrel 1 to the pressure tank 3. After the transportation is completed, remove the clamp, close the liquid inlet 305, open the first manual valve 303, and when pressurizing the pressure tank 3, compressed air enters the pressure tank 3 through the air inlet 307, and the system uses compressed air to transport the liquid in the pressure tank 3 through the outlet The liquid is transported to the pipeline 12 at the liquid inlet 306, and the exhaust valve 121 is opened manually. When the operator sees liquid flowing out of the exhaust pipe, the exhaust valve 121 is closed in time, and a single spray gun flow is set on the display screen 8, and the opening and running time of the liquid inlet valve is set. The spray gun switch (i.e., the corresponding liquid inlet valve switch) is clicked, and the corresponding liquid inlet valve 9 is opened. The system is opened according to the set liquid inlet valve running time, and the spray gun in the corresponding coating pot 11 starts to coat the material in the coating pot 11 with liquid. After the running time set by the system is reached, the liquid inlet valve 9 is automatically closed, and the spray gun in the coating pot 11 stops spraying liquid. During the operation, the operator can also use the liquid inlet valve manual switch 10 to open and close the spray gun according to needs.

The problem that manual spraying of coating liquid not only consumes a lot of labor and has a low degree of automation, but also each coating machine is equipped with a pressure tank and an electronic scale, which makes the equipment occupy a large space and increases the cost of equipment investment. The existing traditional manual control of the spraying method is difficult to control during pressurization, and the amount of the spray cannot be kept consistent. The important parameters of the equipment (spraying pressure, time, etc.) cannot be set and recorded in the control system. In addition, due to manual operation techniques and proficiency, the thickness of the sugar coating on the surface of pills and tablets between different batches is prone to uneven.
