Description

Technical Field

[0001] The utility model belongs to the technical field of paint processing, and in particular relates to a paint production and mixing device. Background Art

[0002] With the continuous development of society and the economy, people's living standards are constantly improving, and their pursuit of a higher quality of life is becoming increasingly demanding. Paint, in particular, is widely used in the current construction industry. This material can be applied to surfaces using various construction techniques, forming a solid, continuous film with strong adhesion and a certain strength. Modern paints are becoming a versatile engineering material and a key component of the chemical industry. Paints can be inorganic, such as electroplated copper, nickel, and zinc, or organic, such as most organic polymers, which constitute a major portion of the current coatings market. The 20th century saw significant developments in paint technology, resulting in the emergence of paints with greater adhesion, higher gloss, flame retardancy, corrosion resistance, and thermal stability in a variety of colors. As the pursuit of aesthetically pleasing paints continues to rise, multiple paints are often mixed and blended in a paint mixing can during actual use and production.

[0003] Currently, a Chinese patent with publication (announcement) number CN213528495U discloses a paint mixing device for paint production, comprising a base and a paint mixing bucket. The base is mounted with a bracket, a motor is mounted on the upper portion of the bracket via a crossbar, and a stirring shaft extending downwardly from the motor into the paint mixing bucket is mounted downwardly. The stirring shaft is characterized in that: a plurality of paddle-shaped stirring rods and spiral blades are mounted simultaneously on the stirring shaft; the spiral blades are mounted around the stirring shaft and generate a downward thrust on the paint when driven by the motor to rotate; the paint mixing bucket is provided with a bucket cover, a shaft seal is provided between the bucket cover and the stirring shaft, and the bucket cover is also provided with a discharge pipe. The stirring shaft of the utility model is designed with both stirring rods and spiral blades; the spiral blades increase the vertical convection of the paint in the paint mixing bucket, resulting in a better stirring effect and improved paint production quality.

[0004] However, the above-mentioned paint mixing device has a single stirring mode, which may prolong the time required for the paint to be fully mixed during stirring. For some paints containing multiple components with different specific gravities and different particle sizes, a single stirring force may not be able to quickly and evenly disperse these components, affecting the efficiency of stirring and mixing the paint.

The static mixer is adapted to the size of the interior of the premixing tank and can be stably placed in the premixing tank for use. A discharge pipe is installed at one end of the center of the lower surface of the premixing tank. The discharge pipe is connected to the feed pipe by a ball valve, and the discharge pipe and the feed pipe can adjust the flow state of the paint through the ball valve.

[0010] As a further solution of the present invention, the mixing assembly includes a motor, which is located at the upper end of the paint mixing box. One end of the motor output shaft is connected to a stirring shaft, and the other end of the stirring shaft is inserted into the paint mixing box.

A feed pipe 7 is provided on one side of the paint mixing box 2, and the feed pipe 7 is connected to the paint mixing box 2. A discharge pipe 13 is installed at one end of the lower center surface of the inner wall of the paint mixing box 2, and the discharge pipe 13 is also connected to the paint mixing box 2. An on-off valve 14 is installed at one end of the discharge pipe 13.

[0028] Among them, through the design of the paint mixing box 2, the premixing tank 6, and the mixing component 4, the raw materials required for paint mixing are added to the premixing tank 6 in advance during the paint mixing process, and the raw materials are preliminarily mixed by the premixing tank 6. When the raw materials enter the paint mixing box 2, the mixing time required for stirring can be reduced. Afterwards, through the coordinated use of the mixing component 4, the different paint components can be quickly and fully mixed to achieve the required color, viscosity and performance requirements, thereby improving the efficiency of the entire paint mixing process and reducing the time consumed in mixing.

[0029] See attached Figure 1 -Attached Figure 3 As shown, a tank cover 10 is installed on one end of the upper surface of the premixing tank 6 by removing bolts, and a feed port 11 is provided on the upper surface of the tank cover 10. A static mixer 12 is installed in the premixing tank 6. The static mixer 12 is adapted to the size of the interior of the premixing tank 6 and can be stably placed in the premixing tank 6 for use. A discharge pipe 9 is installed at one end of the center of the lower surface of the premixing tank 6. The discharge pipe 9 is connected to the feed pipe 7 by a ball valve 8. The flow state of the paint can be adjusted by the ball valve 8.

[0030] Among them, through the design of the premixing tank 6, the feed port 11, the static mixer 12, and the ball valve 8, when the raw materials enter the premixing tank 6 from the feed port 11, the static mixer 12 can evenly mix the paint components of different viscosities and different particle sizes, reducing quality problems caused by uneven components, thereby reducing the mixing time required for later stirring, and making the paint more uniform during the paint mixing process. Afterwards, the switch of the ball valve 8 is adjusted according to production needs to control the flow state of the paint between the discharge pipe 9 and the feed pipe 7, thereby realizing precise control of the premixing paint mixing process.

[0031] See attached Figure 4 -Attached Figure 5 As shown, the mixing assembly 4 includes a motor 401, which is located at the upper end of the paint mixing box 2. One end of the output shaft of the motor 401 is connected to a stirring shaft 402, and the other end of the stirring shaft 402 is inserted into the paint mixing box 2. A shaft seal 3 is provided between the paint mixing box 2 and the stirring shaft 402. Multiple groups of stirring paddles 403 are installed on one end of the surface of the stirring shaft 402. The stirring paddles 403 are distributed in the upper, middle and lower directions, and each group of stirring paddles 403 has a serrated groove on one end.

[0033] Working principle: The raw materials required for paint mixing are poured into the feed port 11, and then the raw materials flow into the static mixer 12 in the premixing tank 6. The poured raw materials are efficiently preliminarily mixed by the static mixer 12. The static mixer 12 utilizes the flow of the fluid itself and the special internal structure, and does not require external power. The staff then turns the ball valve 8 to switch, so that the preliminarily mixed raw materials flow from the discharge pipe 9 into the feed pipe 7 at one end, and the raw materials enter the paint mixing box 2 through the feed pipe 7. The motor 401 then drives the stirring shaft 402, so that the stirring paddle 403 and the earth-shaped stirring block 404 installed on the surface of the stirring shaft 402 evenly mix and stir the inflowing raw materials. After the stirring is completed, turn the switch valve 14 to discharge the mixed paint material from the discharge pipe 13.
