[0018] The utility model is implemented as follows Figure 1 As shown in the figure, an automatic mixing device for coating mixing ratio includes a mixing box 1. Preferably, the mixing box 1 is a cylindrical structure. A plurality of storage boxes 2 are arranged in the mixing box 1. Each storage box 2 is provided with a capacitive liquid level sensor 20. A feed pipe 21 and a discharge pipe 22 are also arranged on the storage box 2. The feed pipe 21 is located at the top of the storage box 2 and passes through the top of the mixing box 1. The feed pipe 21 is connected to an external feeder for supplying raw materials through a pipeline seal, or the feed pipe is covered with a sealing cover. This prevents air from entering the storage box 2 and can slow down the solidification of the raw materials. The discharge pipe 22 is located in the middle position of the bottom end of the storage box 2. The discharge pipe 22 is provided with a first solenoid valve 23 electrically connected to the capacitive liquid level sensor 20. The mixing box 1 is provided with an anti-curing mechanism to prevent the paint raw materials in the storage box 2 from solidifying. The mixing box 1 is provided with a paint mixing mechanism located below the storage box 2. The bottom end of the mixing box 1 is provided with a discharge port 10, and the discharge port 10 is provided with a second solenoid valve 11.

[0019] The amount of raw materials in the storage box 2 is sensed by the capacitive liquid level sensor 20. When the capacitive liquid level sensor 20 senses that the amount of raw materials in the storage box 2 flowing into the mixing machine box 1 reaches a set proportion, the first solenoid valve 23 is closed, so that the mixing device automatically completes the mixing ratio of the paint, which is very convenient. The capacitive liquid level sensor 20 can also be electrically connected to a feeder that supplies raw materials externally. When the capacitive liquid level sensor 20 senses that there is not enough raw materials in the storage box 2, the external feeder feeds the material into the storage box 2, thereby enhancing the degree of automation of the mixing device. At the same time, the anti-curing mechanism is used to prevent the raw materials in the storage box 2 from curing. When the paint mixing is completed, the second solenoid valve 11 is opened, and the mixed paint can be obtained from the discharge port 10.
