[0014] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0015] Depend on Figures 1 to 3 It is known that a paint color mixing device includes a tank body 1, with multiple support legs 11 at the bottom of the tank body 1, a hollow rotating shaft 2 rotatably arranged inside the tank body 1, multiple stirring rods 3 extending outward from the outside of the rotating shaft 2, a plunger 4 at the top of the rotating shaft 2, a feeding port 5 at the bottom of the rotating shaft 2, a discharge port 6 at the bottom of the tank body 1, and multiple feeding pipes 7 connected to the plunger 4 at the top of the tank body 1. The feeding pipes 7 are connected to a material cylinder 8, and a discharge pipe 9 connected to a negative pressure device 10 is provided at the upper end of the plunger 4. The discharge pipe 9 is used to suck out the paint retained in the rotating shaft 2.

[0016] In practical use, this utility model

[0017] Different base colors of paint are added to multiple barrels 8. Depending on the paint to be prepared, different volumes of paint are added to tank 1. Then, the rotating shaft 2 drives the stirring rod 3 to stir and mix them to complete the color matching.

[0018] After the paint is tinted, it is discharged from the outlet 6. Then the feeding pipe 7 is cleaned. The negative pressure device 10 is started, and the paint remaining in the rotating shaft 2 is sucked out through the discharge pipe 9, so that the paint in the pipe is adsorbed out, thereby emptying the pipe and making it easier to tint the next time, so as to avoid affecting the next tinting.

[0019] The tank body 1 is equipped with a fixed rod 12 for supporting the rotating shaft 2. A motor 13 for driving the rotating shaft 2 is fixed on the top of the tank body 1. The motor 13 drives the rotating shaft 2 to rotate on the fixed rod 12. The liquid level of the coating in the tank body 1 is lower than that of the fixed rod 12.

[0020] To facilitate the absorption of coating material from the rotating shaft 2, the plunger 4 has multiple through holes 14 that connect to the feeding pipe 7. Each through hole 14 has an air hole 15 on its side. The feeding pipe 7 is equipped with a first control valve, and the air hole 15 is equipped with a first check valve. The flow direction of the first check valve is from the outside into the air hole 15. The feeding port 5 is equipped with a second check valve. The flow direction of the second check valve is from the inside of the rotating shaft 2 to the outside. The discharge pipe 9 is equipped with a second control valve.

[0021] During feeding, the first control valve is opened, and the coating enters the rotating shaft 2 through the through hole 14 and enters the tank 1 through the second one-way valve. During cleaning, the first control valve is closed and the second control valve is opened, and the negative pressure device 10 generates negative pressure. The discharge pipe 9 extracts the coating in the rotating shaft 2. At this time, the second one-way valve is closed and the first one-way valve is opened, so that the airflow can enter the rotating shaft 2, thereby balancing the pressure in the rotating shaft 2 and allowing the coating to be discharged smoothly.

[0022] Compared with the prior art, this utility model has the following advantages: it sets up negative pressure cleaning of the pipeline, and can perform negative pressure extraction of the pipeline after the paint color is adjusted to avoid paint residue; in order to achieve further cleaning, a clean water pipeline can be connected to the outside of the air hole, and clean water enters the inside of the rotating shaft for cleaning during negative pressure extraction, thereby improving the cleaning effect, ensuring the cleanliness of the pipeline, and not affecting the next paint color adjustment.
