Description

Technical Field

[0001] This utility model relates to the field of water-based coating mixing technology, specifically to a multi-raw material mixing device for water-based coatings. Background Technology

[0002] Water-based coatings are any coatings that use water as a solvent or dispersion medium. Based on the type of binder in the coating, water-based coatings are divided into two main categories: natural water-based coatings using natural substances or minerals (such as potassium silicate) and petrochemical water-based coatings using synthetic resins (such as acrylic resins). Water-based coatings refer to coatings formulated with post-emulsified emulsions as the film-forming agent. Solvent-based resins are dissolved in organic solvents, and then, with the help of emulsifiers, the resins are dispersed in water through strong mechanical stirring to form an emulsion. This is called a post-emulsified emulsion. The resulting coating can be diluted with water during application. Water-dispersible coatings mainly refer to coatings formulated with synthetic resin emulsions as the film-forming agent. During use, multiple raw materials need to be mixed using a mixing device.

[0003] The existing technology has the following problems:

[0004] Current multi-raw material mixing devices for water-based coatings have relatively simple structural performance. Furthermore, the current mixing structure is a monolithic design, resulting in significant residue buildup on its surface after mixing, making disassembly and cleaning difficult. Additionally, the lack of a filtration system means that impurities in the water-based coating can mix with it, affecting the quality of the coating.

[0005] Therefore, we need a multi-raw material mixing device for water-based coatings to solve the above problems. Utility Model Content

[0006] This invention provides a multi-raw material mixing device for water-based coatings to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0009] A filter assembly is provided on the lower surface of the end cap. A mounting column is provided at the lower end of the motor output shaft. Several stirring components are mirror-arranged on the left and right sides of the outer surface of the mounting column. A rotating shaft is movably connected to the bottom of the inner wall of the mixing tank. A rhombus-shaped block one is fixedly connected to the upper end of the rotating shaft. A rhombus-shaped block two is fixedly connected to the lower end of the motor output shaft. The outer surface of the rhombus-shaped block two is inserted into the interior of the mounting column. A scraper is slidably connected through the lower part of the outer surface of the motor output shaft.

[0010] A further improvement of this utility model is that the output shaft of the motor passes through the end cover and the filter assembly and is movably connected inside, and the outer surface of the rhomboid block is inserted into the lower end of the mounting column.

[0011] A further improvement of the present invention is that each of the several stirring components includes a U-shaped block, a mounting plate, and a stirring rod.

The inner walls of the front and rear through grooves are connected to each other on the left and right sides. Limiting grooves are provided on the upper and lower sides of the left side of the mounting plate near the circular opening, and the inner walls of the upper and lower limiting grooves are connected to the inside of the circular opening.

[0013] A further improvement of this utility model is that a circular block is fixedly connected to the left end of the stirring rod, and anti-detachment blocks are fixedly connected to both the front and rear sides of the outer surface of the circular block.

[0014] A further improvement of this utility model is that the outer surface of the circular block is inserted into the interior of the circular opening, and the outer surfaces of the front and rear anti-detachment blocks correspond to the upper and lower limiting grooves.

[0015] A further improvement of this utility model is that the spring is in a contracted state, and the end face of the spring is in contact with the surface of the circular block.

[0019] 1. This utility model provides a multi-raw material mixing device for water-based coatings. After use, the stirring rod can be pushed and the spring squeezed and contracted to separate the anti-detachment block from the limiting groove. Then, the stirring rod can be rotated to an appropriate position, and the anti-detachment block can be moved out of the through groove due to the action of the contracted spring. The setting of rhombus block one and rhombus block two facilitates the removal of the mounting column from the inside of the mixing tank.

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] Example 1: As Figures 1 to 6 As shown, this utility model provides a multi-raw material mixing device for water-based coatings, including a mixing tank 1. An end cap 2 is threadedly connected to the upper inner wall of the mixing tank 1. The threaded connection facilitates the disassembly of the end cap 2, allowing for easy entry or exit of the water-based coating. A motor 4 is fixedly connected to the middle of the upper surface of the end cap 2. The motor 4 facilitates the driving of subsequent structures, improving the mixing effect of the water-based coating. A U-shaped handle 3 is fixedly connected to the upper surface of the end cap 2, facilitating the rotation and removal of the end cap 2. A feed pipe 5 is fixedly connected through the side of the upper surface of the end cap 2 closest to the motor 4, facilitating the entry of raw materials. In addition, the motor 4 is electrically connected via a power supply and electrical wires.

[0030] A filter assembly 6 is provided on the lower surface of the end cap 2, and a mounting column 7 is provided at the lower end of the output shaft of the motor 4. Several stirring components 8 are mirror-image arranged on the left and right sides of the outer surface of the mounting column 7. This structure allows the water-based coating to be filtered first when it enters the mixing tank 1. The filtered water-based coating then enters the mixing tank 1, and the water-based coating is stirred and mixed by the cooperation of the motor 4, the mounting column 7, and the stirring components 8. A rotating shaft 11 is movably connected to the bottom of the inner wall of the mixing tank 1. A rhombus-shaped block 12 is fixedly connected to the upper end of the rotating shaft 11. A rhombus-shaped block 41 is fixedly connected to the lower end of the output shaft of the motor 4. The outer surface of the rhombus-shaped block 41 is inserted into the interior of the mounting column 7, and the outer surface of the rhombus-shaped block 12 is inserted into the lower end of the mounting column 7. In addition, diamond-shaped openings are provided at both the top and bottom of the mounting column 7 to facilitate the insertion of two diamond blocks. The structure of diamond block 12 and diamond block 41 inserted into the mounting column 7 facilitates the installation and removal of the mounting column 7 after use, making it easy to remove the mounting column 7 from the inside of the mixing tank 1 and disassemble it. A scraper 42 is slidably connected through the lower outer surface of the output shaft of the motor 4. This structure allows the scraper 42 to be removed for easy cleaning of surface residue. When the motor 4 is started during use, the scraper 42 can be rotated to prevent the accumulation of water-based coatings and speed up the filtration process. The output shaft of the motor 4 is movably connected through the end cover 2 and the filter assembly 6.

[0031] Example 2: Figures 1 to 6As shown, each of the several stirring components 8 includes a U-shaped block 81, a mounting plate 82, and a stirring rod 87. The front and rear horizontal directions of the U-shaped block 81 are fixedly connected to the surface of the mounting column 7. The surface of the mounting plate 82 is fixedly connected to the left and right horizontal surfaces of the U-shaped block 81. A spring 86 is fixedly connected to the middle of the front and rear horizontal direction of the U-shaped block 81. The spring 86 ensures that after installation, the anti-detachment block 89 is tightly fitted with the inside of the limiting groove 85 under the elastic action of the spring 86, preventing any loosening. A circular opening 83 is provided in the middle of the right side of the mounting plate 82, which facilitates the insertion of the circular block 88. The inner wall of the circular opening 83 has through grooves 84 on both the front and rear sides. During installation, the anti-detachment block 89 can be aligned with the through groove 84. The position is used for loading and unloading. The inner walls of the front and rear through grooves 84 are connected to each other on the left and right sides. The upper and lower sides of the left side of the mounting plate 82 are provided with limit grooves 85 near the circular opening 83. When the limit grooves 85 are used in conjunction with the anti-detachment blocks 89, they have a limiting function after the stirring rod 87 is installed. The inner walls of the upper and lower limit grooves 85 are connected to the inside of the circular opening 83. The left end of the stirring rod 87 is fixedly connected to a circular block 88. The outer surface of the circular block 88 is fixedly connected to the front and rear sides with anti-detachment blocks 89. The outer surface of the circular block 88 is inserted into the inside of the circular opening 83. The outer surfaces of the front and rear anti-detachment blocks 89 correspond to the upper and lower limit grooves 85, and the two are inserted to limit the movement. The spring 86 is in a contracted state, and the end face of the spring 86 is in contact with the surface of the circular block 88.

[0032] During installation, the anti-detachment block 89 is aligned with the inside of the through groove 84, and the stirring rod 87 is pushed to compress and contract the spring 86. After the circular block 88 passes through the circular opening, the stirring rod 87 is rotated to the appropriate position, aligning the anti-detachment block 89 with the limiting groove 85. Then, the stirring rod 87 is released. Due to the elasticity of the spring 86, the circular block 88 and the stirring rod 87 are moved, causing the anti-detachment block 89 to enter the inside of the limiting groove 85, thereby achieving a position locking effect and facilitating installation.

[0033] Example 3: Figures 1 to 6As shown, the lower surface of the end cap 2 is provided with an annular threaded groove 21. The filter assembly 6 includes an annular sleeve 61. The upper surface of the annular sleeve 61 is threadedly connected to the inner surface of the annular threaded groove 21. This structure facilitates installation and removal and provides a cleaning effect on the residue in the filter assembly 6. A filter plate 62 is fixedly connected to the lower inner wall of the annular sleeve 61. The filter plate 62 facilitates the filtration of water-based coatings and prevents impurities from entering. The inner diameter of the annular sleeve 61 is the same as the length of the scraper 42. The two ends of the scraper 42 are in contact with the inner wall of the annular sleeve 61 to prevent the scraper 42 from moving during rotation. The upper surface of the filter plate 62 corresponds to the lower surface of the scraper 42 and they are in contact. When the motor 4 is started, the output shaft drives the scraper 42 to rotate and stir on the surface of the filter plate 62.

[0034] Working principle: When in use, the motor 4 is started to drive the mounting column 7 and the stirring component 8 to rotate, which facilitates the stirring and mixing of the water-based coating inside the mixing tank 1. Before entering the mixing tank 1, the water-based coating first enters the interior of the filter component 6. The rotation of the scraper 42 stirs the accumulated water-based coating to accelerate the filtration speed, and then it enters the interior of the mixing tank 1 for stirring and mixing.

[0035] After use, rotate the U-shaped handle 3 to separate the end cap 2 from the inside of the mixing tank 1 and remove it. At this time, the second rhombus block 41 separates from the mounting post 7. Then move the mounting post 7 out so that the first rhombus block 12 separates from the mounting post 7. Next, push the stirring rod 87 to squeeze the spring 86 so that the anti-detachment block 89 separates from the limiting groove 85. Then rotate the stirring rod 87 to drive the circular block 88 and the anti-detachment block 89 so that the anti-detachment block 89 corresponds to the through groove 84. Move the stirring rod 87 outward to complete the disassembly operation. Then rotate the annular sleeve 61 to separate it from the annular thread groove 21 and pull the second rhombus block 41 to separate it from the output shaft of the motor 4 to facilitate cleaning of the surface residue of the parts.

[0036] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
