Specifically, by adopting the above technical scheme, when the first rotating device 201 rotates to a certain position, the rubber plug 303 is located directly below the corresponding squeeze outlet 216, and at this time the lifting device 301 controls the star-shaped lifting plate 302 to move upwards, and the rubber plug 303 can smoothly plug the bottom of the squeeze outlet 216, preventing the paint from dripping under the influence of gravity, and also preventing the paint from contacting the air.

[0055] In the specific use process, the user first selects the specified color in the operation panel 105 through the hue ring, inputs the total demand of the pigment, and then places the pigment tray at the material taking port 104. The operation panel 105 analyzes the input data, judges the demand amount of each color pigment according to the data by using the CMKY color matching method, and then starts the lifting device 301 to control the star-shaped lifting plate 302 to descend, so that the rubber plug 303 is separated from the corresponding extrusion port 216. The first rotating device 201 is started to drive the first connecting plate 202 to rotate, so that the extrusion port 216 of the pigment of one color is located above the discharge port 106. After that, the first rotating device 201 stops, the second rotating device 204 is started, the second gear 208 is rotated through the first gear 205, and then the force is transmitted to the transmission rod 213 through the embedded transmission part 209 to control the transmission rod 213 to slowly move downward. The pigment push head 217 will extrude the pigment in the lower pigment pipe 215 from the extrusion port 216, and the extruded pigment will fall into the pigment tray through the discharge port 106. After reaching the specified amount, the second rotating device 204 immediately stops, the first rotating device 201 is started, and the above operation is repeated. After the extrusion of the pigment is completed, the first rotating device 201 is started, and after returning to the original position, the operation is stopped. The lifting device 301 is started to control the star-shaped lifting plate 302 to rise, and the rubber plug 303 blocks the corresponding extrusion port 216 to prevent the leakage of the pigment. Then the user takes out the pigment tray, stirs the pigment uniformly, and then the desired color can be obtained, and the metering and demand amount are consistent.

The ordinary technical personnel in the field knows all the ordinary technical knowledge in the technical field of the present application before the application date or the priority date, can know all the prior art in the field, and has the ability to apply the conventional experimental means before the date. The ordinary technical personnel in the field can improve and implement the present scheme based on their own ability under the inspiration of the present application. Some typical known structures or known methods should not be an obstacle for the ordinary technical personnel in the field to implement the present application. It should be noted that for the technical personnel in the field, without departing from the structure of the present application, a number of modifications and improvements can be made, which should be considered as the protection scope of the present application. These will not affect the effect and practicality of the present application.
