The general composition of building coatings includes film-forming substances, pigments and fillers, solvents, and additives.

[0003] In the actual production process, the raw materials of building coatings are poured into the mixing container in sequence, which easily causes layering in the mixing container, greatly increasing the mixing time. And there is a phenomenon of caking and agglomeration of powder raw materials before adding. Although building coatings allow the presence of agglomerated raw materials with a certain diameter, traditional mixing blades can only break large agglomerated raw materials into small pieces, and the diameter of the small raw materials far exceeds the allowable diameter range, making it difficult to mix the raw materials evenly and affecting the uniformity of building coatings. Therefore, a mixing and stirring device for building coatings is proposed. Summary of the Invention

Specific embodiments

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0023] Referring to Figure 1-7 As shown, a building paint mixing and stirring device includes a barrel body 1 and a stirring and crushing mechanism 2. A barrel cover 11 is installed on the barrel body 1. A feed inlet 13 is provided at the top of the barrel cover 11. A discharge outlet 14 is provided at the bottom of the barrel body 1. The stirring and crushing mechanism 2 is arranged in the barrel body 1 and is used for stirring the paint raw materials in the barrel body 1 and crushing the lumps in the raw materials. The stirring and crushing mechanism 2 includes a motor 21 and an inner cylinder 22. The motor 21 is installed on the barrel cover 11. The output shaft of the motor 21 penetrates the barrel cover 11 and is coaxially connected with a main shaft 211. The inner cylinder 22 is installed on the bottom inner wall of the barrel body 1. The inner cylinder 22, the main shaft 211 and the barrel body 1 are all coaxially arranged. The part of the main shaft 211 located inside the inner cylinder 22 is connected with an auger stirring blade 221. A plurality of material passing ports 222 are opened at the bottom of the inner cylinder 22.

[0024] In this embodiment, a disc-shaped top seat 23 is connected to the top of the inner cylinder 22. The top seat 23 is rotatably connected to the main shaft 211. The upper end of the main shaft 211 is slidably and rotatably connected to a conical lifting seat 24. The bottom of the lifting seat 24 is connected to a sleeve 25. A plurality of outer mesh holes 253 are formed in the sleeve 25. A plurality of inner mesh holes 223 are formed in the top region of the inner cylinder 22. A plurality of arc-shaped guide grooves 252 are formed in the annular side wall of the top seat 23. A plurality of guide blocks 251 are connected to the inner cylinder wall of the sleeve 25. Each guide block 251 is slidably connected to the corresponding guide groove 252 on the top seat 23. The inner mesh holes 223 and the outer mesh holes 253 are identical in shape and size.

[0025] In this embodiment, a lifting plate 26 is slidably connected to the upper end of the inner cylinder 22. The lifting plate 26 is slidably and rotatably connected to the main shaft 211. A first chute 231 is formed in the bottom of the top seat 23. A second chute 232 communicating with the first chute 231 is formed in the top of the top seat 23. A first slider 233 is hermetically slidably connected in the first chute 231. The lower end of the first slider 233 is connected to the lifting plate 26. A second slider 234 is hermetically slidably connected in the second chute 232. The upper end of the second slider 234 abuts against the lifting seat 24. A plurality of first springs 261 are connected to the upper end surface of the lifting plate 26. The upper ends of the plurality of first springs 261 are connected to the top seat 23. The first chute 231 and the second chute 232 are filled with hydraulic oil. The cross-sectional area of the second chute 232 is three times that of the first chute 231. When the first slider 233 is pushed to slide, the sliding distance of the second slider 34 through hydraulic transmission is one-third of that of the first slider 233, reducing the lifting distance of the sleeve 25 and facilitating the control of the overlapping aperture size of the inner mesh holes 223 and the outer mesh holes 253.

[0026] In this embodiment, a groove 27 is formed in the top of the top seat 23. A moving block 271 is slidably connected in the groove 27. An electric cylinder 272 is installed at the bottom of the groove 27. The movable end of the electric cylinder 272 is connected to the bottom of the moving block 271. The upper end of the moving block 271 is connected to a second spring 273. The upper end of the second spring 273 is connected to the lifting seat 24. The second spring 273 is always in a stretched state. By pulling the moving block 271 and the second spring 273 by the electric cylinder 272, the position of the sleeve 25 is changed, thereby controlling the overlapping aperture size of the inner mesh holes 223 and the outer mesh holes 253.

[0027] In this embodiment, a connecting rod 28 is connected to the upper end of the main shaft 211, and a spiral scraper 281 is connected to the lower end of the connecting rod 28. The inner and outer sides of the spiral scraper 281 are respectively in contact with the outer wall of the inner cylinder 22 and the inner wall of the barrel 1. When the spiral scraper 281 rotates following the main shaft 211, it can scrape off the raw materials on the outer wall of the inner cylinder 22 and the inner wall of the barrel 1, ensuring that the raw materials fully participate in the mixing.

[0028] The working process and principle of the present invention are as follows: During use, various raw materials are added into the barrel 1 through the feed port 13 on the barrel cover 11, and the automatic motor 21 drives the main shaft 211 to rotate, and the various raw materials are stirred and mixed by the rotating auger stirring blade 221 and the spiral scraper 281.

[0029] When there is no caking or agglomeration in the raw materials, the raw materials in the barrel 1 enter the inner cylinder 22 through the material passing port 222, are lifted by the auger stirring blade 221, and then flow to the upper layer of the liquid surface through the inner mesh holes 223 and the outer mesh holes 253, enabling the various raw materials to be quickly mixed, reducing the influence of the increased stirring time caused by the layering due to the batchwise extrusion of the various raw materials, and improving the stirring and mixing efficiency.

[0030] When there is caking in the raw materials, the caked raw materials are lifted by the rotating auger stirring blade 221. Under the centrifugal action of the rotation of the auger stirring blade 221, the caked raw materials will adhere to the inner wall of the inner cylinder 22. When the caked raw materials reach the height where the inner mesh holes 223 are located, the caked raw materials will be pushed into the inner mesh holes 223 after being pushed, achieving preliminary crushing. Since the initial position of the sleeve 25 at this time makes the overlapping aperture of the inner mesh holes 223 and the outer mesh holes 253 smaller, the caked raw materials with the size of the inner mesh holes 223 after preliminary crushing will be blocked in the inner mesh holes 223, affecting the flow of other raw materials. As the number of blocked inner mesh holes 233 increases, the raw materials flowing out through the inner mesh holes 223 and the outer mesh holes 253 decrease, and the amount of raw materials in the inner cylinder 22 accumulates continuously. The height of the raw materials will rise and exert pressure on the lifting plate 26, pushing the lifting plate 26 to slide upward. Through the hydraulic transmission between the first slider 231 and the second slider 232, the lifting seat 24 and the sleeve 25 will spiral upward along the guide groove 252 to the highest position, making the inner mesh holes 223 and the outer mesh holes 253 completely overlap. The caked raw materials blocked in the inner mesh holes 223 will be pushed by other raw materials through the outer mesh holes 253. After a period of time, the large caked raw materials are basically broken into caked raw materials with the size of the inner mesh holes 223 and pass through the mesh holes 223 and the outer mesh holes 253. The height of the raw materials at the top of the inner cylinder 22 will slowly decrease, and the pressure on the lifting plate 26 will gradually decrease. Under the elastic force of the first spring 261, it will push the lifting 26 to slowly slide back downward, and the sleeve 25 will spiral downward more slowly, making the overlapping aperture of the inner mesh holes 223 and the outer mesh holes 253 gradually decrease. The caked raw materials with the size of the inner mesh holes 223 will come to the top of the inner cylinder 22 again through circulation and will be squeezed and broken into caked raw materials with the size of the overlapping aperture of the inner mesh holes 223 and the outer mesh holes 253. After the pressure of the lifting plate 26 continuously decreases and the sleeve 25 continuously spirals downward to the initial position, the caked raw materials are broken multiple times to meet the requirements of architectural coatings, making the raw materials mix evenly and ensuring the quality of the mixed architectural coatings.

[0031] When mixing and stirring according to the different particle size requirements of different architectural coatings, the electric cylinder 272 can be turned on to pull the moving block 271 to slide, changing the initial staying position of the sleeve 22, and thus controlling the overlapping aperture size of the inner mesh holes 223 and the outer mesh holes 253, so as to control the crushing degree of the caked raw materials and improve the mixing and stirring efficiency on the premise of meeting the coating requirements.
