Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of paint dilution equipment, and in particular to a paint dilution device for architectural paint production. Background Technology
[0002] Architectural coatings are materials used for painting building surfaces, primarily for decoration and protection. They typically consist of film-forming substances (such as resins), pigments, solvents, and additives. During production or application, coatings need to reach a specific viscosity to meet the requirements of spraying, brushing, or rolling. Dilution devices precisely adjust the viscosity of the coating by adding diluents (such as water or solvents) to make it more suitable for application.
[0003] In existing architectural coating production technologies, the mixing process of coatings and thinners mainly relies on the rotation of stirring blades. While this mixing method can mix materials to a certain extent, the stirring blades are limited to their own rotational motion during the mixing process, and the tank itself does not rotate with them. This leads to dead zones and stratification during the mixing process, especially in large-capacity tanks, where the mixing effect is poor. Since the tank cannot rotate with the stirring blades, the flow of materials mainly depends on the rotational power of the stirring blades. This flow method often fails to cover all corners of the tank, especially near the bottom and side walls, where the problem of insufficient material mixing is particularly prominent. This not only affects the uniformity and quality of the coating but may also increase energy consumption and maintenance costs during the production process. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Reference Figure 2 , Figure 3 and Figure 5This utility model provides an embodiment of a paint dilution device for architectural coating production, comprising a support base 1, a motor 13 fixedly connected inside the support base 1, a rotating shaft 14 fixedly connected to the output end of the motor 13, a driving pulley 15 fixedly connected to the outside of the rotating shaft 14, a driven pulley 17 connected to the driving pulley 15 via a belt 16, a transmission rod 18 fixedly connected inside the driven pulley 17, a mounting frame 21 fixedly connected to the upper part of the transmission rod 18, a motor 22 fixedly connected inside the mounting frame 21, a rotating rod 23 fixedly connected to the output end of the motor 22, and a rotating rod 23 fixedly connected to the outside of the rotating rod 23. A stirring assembly is fixedly connected to all four sides of the tank body 3. The stirring assembly is used to stir the coating. The stirring assembly includes rings 24 and stirring blades 25. Multiple rings 24 are fixedly connected to the outer periphery of the rotating rod 23. Multiple stirring blades 25 are fixedly connected to the outer periphery of the multiple rings 24. Multiple stirring blades 25 are rotatably connected to the inside of the tank body 3. A discharge pipe is fixedly connected to the front of the tank body 3. Connecting rods 19 are fixedly connected to all four sides of the bottom of the tank body 3. Limiting blocks 20 are fixedly connected to the bottom of multiple connecting rods 19. Limiting grooves are opened inside the fixed base 2. Multiple limiting blocks 20 are slidably connected inside the limiting grooves.
[0025] Paint and thinner are conveyed into the tank 3 through the feed pipe 12. The feed pipe 12 serves as a material input channel, responsible for conveying the paint and thinner into the tank 3. Subsequently, motor 13 is started, and its output drives the rotating shaft 14 to rotate. The rotation of the rotating shaft 14 drives the drive pulley 15 to rotate. The drive pulley 15 transmits power to the driven pulley 17 through the belt 16. The rotation of the driven pulley 17 then drives the transmission rod 18. The rotation of the transmission rod 18 causes the mounting frame 21 and motor 22 to rotate accordingly. The rotation of 21 drives the tank body 3 to rotate. At the same time as the tank body 3 rotates, multiple connecting rods 19 also rotate. The rotation of the connecting rods 19 drives the limiting block 20 to slide smoothly in the limiting groove, controlling and stabilizing the rotational movement of the tank body 3 and preventing excessive tilting or vibration. In addition, the motor 22 is started, and its output end drives the rotating rod 23 and the ring 24 to rotate. The rotation of the ring 24 drives the stirring blade 25 to perform efficient stirring inside the tank body 3, so that the paint and diluent are fully mixed. The discharge pipe is used to discharge the stirred paint from the tank body 3.
[0026] Reference Figure 1 , Figure 2 and Figure 4A fixed base 2 is fixedly connected inside the support base 1. A tank body 3 is rotatably connected inside the fixed base 2. A support plate 4 is fixedly connected to the upper part of the support base 1. A storage tank 5 is fixedly connected to the upper part of the support plate 4. A hydraulic cylinder 7 is fixedly connected to the upper part of the storage tank 5. A baffle 8 is fixedly connected to the output end of the hydraulic cylinder 7. A feed hopper 6 is fixedly connected to the left side of the storage tank 5. Limiting rods 9 are fixedly connected to both sides of the upper part of the baffle 8. A circular plate 10 is fixedly connected to the upper part of both limiting rods 9. Both limiting rods 9 are slidably connected to the inner sides of the tank body 3. A return spring 11 is sleeved on the outside of both limiting rods 9. One end of both return springs 11 is fixedly connected to the bottom of the circular plate 10. The other end of both return springs 11 is fixedly connected to the upper part of the storage tank 5. A discharge pipe 12 is fixedly connected to the bottom of the storage tank 5. The discharge pipe 12 is located on the upper part of the tank body 3. A scale is provided at the front of the storage tank 5.
[0027] Start hydraulic cylinder 7, its output end pushes baffle 8 downward. Baffle 8 transmits power and controls the amount of material added. During the movement of baffle 8, it drives limit rod 9 to slide inside storage tank 5. The sliding action of limit rod 9 drives circular plate 10 to move downward. Circular plate 10 compresses return spring 11. Return spring 11 stores energy to provide power for subsequent reset actions. Under the synergistic action of the two limit rods 9, baffle 8 moves downward inside storage tank 5 to the predetermined position. A scale is set at the front of storage tank 5, which provides intuitive position indication, allowing operators to easily monitor the movement of baffle 8 and ensure that it accurately reaches the predetermined position. When baffle 8 reaches the designated position, the operator can add paint and thinner into storage tank 5 through feed hopper 6.
[0028] Working principle: First, hydraulic cylinder 7 is started. The output end of hydraulic cylinder 7 pushes baffle 8 downward. When baffle 8 moves, it drives limit rod 9 to slide inside storage tank 5. When limit rod 9 moves, it drives circular plate 10 downward, causing circular plate 10 to squeeze return spring 11. Under the action of the two limit rods 9, baffle 8 moves downward inside storage tank 5. A scale is set at the front of storage tank 5. When baffle 8 moves to the designated position, paint and thinner are added into storage tank 5 through feed hopper 6, realizing quantitative addition of materials, ensuring accurate ratio of paint to thinner, reducing manual intervention, shortening mixing time, and improving production efficiency. Paint and thinner are transported into tank 3 through discharge pipe 12. Then, motor 13 is started. The output end of motor 13 drives shaft 14 to rotate. The rotation of shaft 14 drives drive pulley 15 to rotate. The driving pulley 15 drives the driven pulley 17 to rotate via the belt 16. The driven pulley 17 drives the transmission rod 18 to rotate. The rotation of the transmission rod 18 drives the mounting frame 21 and the second motor 22 to rotate. The mounting frame 21 drives the tank body 3 to rotate. When the tank body 3 rotates, it drives multiple connecting rods 19 to rotate. The rotation of the connecting rods 19 drives the limiting block 20 to slide inside the limiting groove. Under the action of the limiting block 20, the tank body 3 rotates inside the fixed seat 2. At the same time, the second motor 22 is started. The output end of the second motor 22 drives the rotating rod 23 and the ring 24 to rotate. The rotation of the ring 24 drives the stirring blade 25 to rotate inside the tank body 3, so that the stirring blade 25 stirs the paint and diluent. Finally, the stirred paint is discharged through the discharge pipe, realizing more comprehensive material mixing, effectively reducing dead corners and stratification, improving mixing efficiency, and ensuring that the paint and diluent are mixed more evenly.
