Technical Field

[0001] The utility model relates to the technical field of waterborne coating production, in particular to a waterborne coating mixing device. Background Art

[0002] Any coating that uses water as a solvent or a dispersion medium can be called a waterborne coating. According to the type of binder in the coating, waterborne coatings are divided into two categories: natural waterborne coatings of natural substances or minerals and petrochemical waterborne coatings of synthetic resins. During the production process of waterborne coatings, in order to ensure their coating effect, additional auxiliary agents are often required. During the preparation process, a mixing device is often needed to mix the waterborne coating and the auxiliary agent.

[0003] The Chinese patent authorization announcement number is CN220091149U, and the name is a mixing device for the production of waterproof coatings. It includes a mixing mechanism, a support frame, a motor compartment one, and a motor compartment two. Through the mixing mechanism arranged between the motor compartment one and the motor compartment two, motors are arranged inside the motor compartment one and the motor compartment two. The mixing mechanism includes components such as a turning compartment, a feed inlet, a discharge outlet, and a stirring shaft. Under the mutual cooperation, it can realize the stirring and mixing of the raw materials of the waterproof coating, and the motor in the motor compartment two can drive the turning compartment to turn, so that the raw materials in the turning compartment are turned and poured, avoiding the situation that the materials squeezed into the corner during the stirring and mixing process cannot be well mixed with other materials, thereby reducing the production efficiency of the waterproof coating and possibly affecting the use experience of the waterproof coating during use.

[0004] The deficiencies of the above existing technical solutions are as follows: Although the above solution can effectively avoid the situation that the materials squeezed into the corner cannot be well mixed with other materials, when stirring the waterborne coating, it often takes a long time to stir to ensure that the coatings are evenly mixed together. This method is time-consuming and reduces the production efficiency of the device. Summary of the Utility Model

[0024] As Figures 1-3 shown, an aqueous paint mixing device includes a mixing tank 1, a sealing cover 2 provided on the top of the mixing tank 1, and feed pipes 3 symmetrically provided on the top of the sealing cover 2. The mixing tank 1 is used to store aqueous paint and auxiliary agents, and provides a closed space for subsequent stirring and mixing, ensuring the smooth progress of the stirring and mixing work. The sealing cover 2 seals the mixing tank 1, ensuring the tightness of the device during use and preventing foreign substances from falling into the tank and contaminating the aqueous paint. The feed pipe 3 is used to convey materials into the mixing tank 1;

[0025] It further includes a pre-mixing assembly. The pre-mixing assembly includes conveying pipes 4 symmetrically provided at the bottom of the sealing cover 2 and communicating with the feed pipes 3, a confluence pipe 5 provided between the conveying pipes 4, and a mixing pipe 6 provided at the lower end of the confluence pipe 5. Among them, the mixing pipe 6 is circular, there is a notch on the mixing pipe 6, one end at the notch bends upward and is connected to the confluence pipe 5, and the other end bends downward and is connected to the spraying pipe 8 through the connecting pipe 7.

A spiral blade 10 is arranged inside the mixing pipe 6.

And relying on the drop during spiral flow, the mixed water-based coatings can be agitated, thus further accelerating the mixing between the water-based coatings and the auxiliaries. Then, it is sprayed into the mixing tank 1 through the atomizing nozzle 9.

[0027] In this embodiment, specifically, suspension brackets 11 are symmetrically arranged at the bottom edge of the sealing cover 2. The bottom ends of the suspension brackets 11 are connected to the mixing pipe 6. The overall pre-mixing assembly is suspended and supported by the suspension brackets 11, ensuring the stability of the pre-mixing assembly during operation.

[0028] In this embodiment, specifically, a stirring shaft 12 is rotatably arranged inside the center of the sealing cover 2. A number of groups of stirring paddles 13 are sleeved outside the stirring shaft 12 at intervals. A servo motor 14 for driving the stirring shaft 12 to rotate is arranged at the center of the top of the sealing cover 2. A drain pipe 15 is arranged at the bottom of the mixing tank 1.
