[0002] Powder coatings are a type of solid powder coatings, and their main components are resins, pigments, fillers, and auxiliaries, etc. The particles of powder coatings are in powder form and do not contain solvents. Compared with traditional liquid coatings, they have advantages such as environmental protection and high efficiency. The dispersion medium of powder coatings is air, and it has the characteristics of no solvent pollution, 100% film formation, and low energy consumption. As a type of coating that can effectively save energy and has an environmental protection effect, powder coatings are being widely popularized.

[0017] The water tank 11 is fixedly installed at the right end of the base 1 through the third bracket 12. A water suction pump 13 is fixedly installed on the water tank 11. The water inlet end of the water suction pump 13 is fixedly connected and communicated with a first water suction pipe 14. The other end of the first water suction pipe 14 hangs into the water cup 7. The water outlet end of the water suction pump 13 is fixedly connected and communicated with a first water outlet pipe communicated with the water tank 11. The suction cylinder 16 is fixedly installed on the third bracket 12 through the fourth bracket 17. An inlet and an outlet are respectively provided below the suction cylinder 16. A piston 18 is movably installed in the suction cylinder 16. A pressing block 19 is provided at the upper end of the piston 18. One end of the second water inlet pipe 20 is fixedly connected and communicated with the water tank 11, and the other end is fixedly connected and communicated with the inlet of the suction cylinder 16. One end of the second drain pipe 21 is fixedly connected and communicated with the outlet of the suction cylinder 16, and the other end hangs into the water cup 7. Check valves are respectively communicated and installed on the second water inlet pipe 20 and the second drain pipe 21. A scale ruler 22 is provided on the suction cylinder 16.

[0018] The screw feeding mechanism 10 includes a material guiding pipe 23 and a motor 25. A screw blade 24 is rotatably installed in the material guiding pipe 23.

[0019] Working principle: When 100 grams of a certain colorant is needed, the piston 18 is lifted upward to the 100 ml scale ruler 22. At this time, the check valve of the second drain pipe 21 is closed, and the check valve of the second water inlet pipe 20 is opened. Water enters the suction cylinder 16, and then waits for the pressing block 19 to press the water in the suction cylinder 16 into the water cup 7. Then the power is turned on.

The position induction switch 26 starts the motor 25, and the motor 25 rotates the screw blade 24 to slowly put the colorant into the colorant cup 6. When the weight in the colorant cup 6 is the same as the weight of the water, the induction switch 26 receives the induction piece 27, stops the motor 25, and at the same time the induction switch 26 starts the water suction pump 13 to suck the water in the water cup 7 back into the water tank 11.

Finally, the power is turned off, and the colorant cup 6 is taken out. In this way, colorants with accurate measurement are obtained, realizing that each colorant is stored in a dedicated bin, and the amount needed can be accurately taken out at one time, greatly improving the work efficiency and making the measurement scheme more scientific.
