Detailed implementation manners

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] As Figures 1 to 10 shown, in the embodiment of the present invention, a paint mixing device for producing intumescent fireproof paint includes a paint mixing tank 1. A mixing assembly is arranged inside the paint mixing tank 1. A tank cover 3 is installed at the top of the paint mixing tank 1. A feed inlet 4 is opened at the top of the tank cover 3. A filtering assembly and a control assembly are arranged inside the feed inlet 4. A base 2 is fixedly installed at the bottom end of the paint mixing tank 1. A discharge outlet 5 is fixedly connected to the bottom end of the base 2;

[0041] The mixing assembly includes a stirring shaft 6 arranged inside the paint mixing tank 1. Stirring paddles 7 are fixedly installed on the outer wall of the stirring shaft 6. The stirring paddles 7 are evenly arranged. A motor 8 is installed at the top end of the stirring shaft 6. The motor 8 is arranged inside the tank cover 3;

[0042] The filtering assembly includes a filter screen 9 installed inside the feed inlet 4. A stirring assembly is arranged at the top end of the filter screen 9.

[0043] When producing intumescent fireproof coatings, first, the raw materials are put into the feeding port 4. After being filtered by the filter screen 9, the raw materials enter the paint mixing tank 1. Then, the PLC is used to control the motor 8 to start. When the motor 8 starts, it drives the rotation of the stirring shaft 6. The rotation of the stirring shaft 6 drives the rotation of the stirring paddle 7 to mix the raw materials. Filtering the raw materials through the filter screen 9 can block the agglomerated raw materials with larger particle sizes and prevent them from entering the subsequent production process, thus ensuring the production quality of the coatings.

[0044] As Figures 1 to 7 shown, the stirring assembly includes a mixing plate 10 arranged at the top of the filter screen 9. A pressing component is arranged above the mixing plate 10. An annular gear 11 is fixedly installed on the outer wall of the mixing plate 10. The annular gear 11 is rotatably installed inside the tank cover 3. One side of the annular gear 11 is meshed with a gear 12. A first rotating shaft 13 is fixedly installed inside the gear 12. A pulley group 14 is arranged on the outer wall of the first rotating shaft 13. One end of the pulley group 14 away from the first rotating shaft 13 is installed on the outer wall of the stirring shaft 6.

[0045] When mixing the raw materials, the rotation of the stirring shaft 6 drives the rotation of the first rotating shaft 13 through the transmission of the pulley group 14. The rotation of the first rotating shaft 13 drives the rotation of the gear 12. The rotation of the gear 12 drives the rotation of the annular gear 11. The rotation of the annular gear 11 drives the rotation of the mixing plate 10, causing the mixing plate 10 to rotate on the top of the filter screen 9 and agitate the raw materials above. This can not only agitate the agglomerated raw materials and have a certain effect of breaking them up, but also improve the filtering effect and reduce the blockage of the filter screen 9, thus helping to improve the quality and production efficiency of the coatings.

[0046] As Figures 1 to 8 shown, the pressing component includes a pressing plate 15 arranged above the mixing plate 10. A protective plate 17 is fixedly installed on the outer wall of the pressing plate 15. A rotating ring 18 is fixedly installed on the outer wall of the protective plate 17. The rotating ring 18 is rotatably installed inside the tank cover 3. The rotating ring 18 is arranged above the annular gear 11. The top of the annular gear 11 is evenly installed with first connecting shafts 19 in an annular array. The first connecting shafts 19 are embedded in the inner wall of the rotating ring 18. A moving plate 21 is slidably connected to the outer wall of the rotating ring 18. The moving plate 21 is installed on the outer wall of the first rotating shaft 13. The moving plate 21 is threadedly connected to the first rotating shaft 13.

[0047] A reciprocating thread is arranged on the outer wall of the first rotating shaft 13. When rotating, it makes the moving plate 21 move up and down reciprocally.

[0048] A sliding groove 23 for the up and down sliding of the rotating ring 18 is opened inside the tank cover 3. The protective plate 17 is located on one side of the sliding groove 23 to prevent the raw materials from entering the inside of the sliding groove 23.

[0049] When stirring the raw materials, the rotation of the first rotating shaft 13 drives the movement of the moving plate 21. The movement of the moving plate 21 drives the movement of the rotating ring 18. The movement of the rotating ring 18 drives the movement of the protective plate 17. The movement of the protective plate 17 drives the movement of the pressure plate 15, causing the pressure plate 15 to move towards one side of the mixing plate 10. The approach of the pressure plate 15 to the mixing plate 10 helps to disperse the agglomerated raw materials, which can not only reduce the waste of raw materials in this part, but also improve the filtration efficiency, thereby improving the overall production efficiency.

[0050] As Figures 1 to 8 shown, a first connecting block 20 is fixedly installed on the outer wall of the first connecting shaft 19, and the first connecting blocks 20 are uniformly arranged in an annular array.

[0051] When the annular gear 11 rotates, through the connection between the first connecting shaft 19 and the first connecting block 20, the rotating ring 18 rotates accordingly, so that the pressure plate 15 rotates together with the mixing plate 10 and is always parallel above the mixing plate 10, facilitating pressing the materials;

[0052] And when the moving plate 21 drives the rotating ring 18 to move up and down, the rotating ring 18 slides on the outer wall of the first connecting block 20 to ensure the stability of their connection.

[0053] As Figure 10 shown, convex blocks 16 are fixedly installed on the inner wall of the pressure plate 15, and the convex blocks 16 are evenly distributed.

[0054] During pressing, it helps to disperse the raw materials and improve the effect and efficiency of pressing and dispersing.

[0055] As Figure 8 shown, a slider 22 is slidably installed inside the moving plate 21. A spring 24 is installed between the rotating ring 18 and the slider 22. The bottom end of the slider 22 is embedded in the inner wall of the chute 23, and the chute 23 is opened at the top end of the rotating ring 18.

[0056] When the rotating ring 18 rotates inside the moving plate 21, the slider 22 slides in the inner wall of the chute 23. When the moving plate 21 drives the rotating ring 18 to move downward, the pressure plate 15 approaches one side of the mixing plate 10. Through the elastic potential energy of the spring 24, it has a certain movement space, can be adaptively adjusted according to different raw material characteristics, and can also reduce the large pressure on the filter screen 9 when dispersing the raw materials, thereby ensuring the service life and filtration effect of the filter screen 9.

[0057] As Figures 1 to 6As shown, the control component includes a material control plate 29 disposed inside the feed inlet 4. A third rotating shaft 28 is fixedly installed on the inner wall of the material control plate 29. One end of the third rotating shaft 28 is provided with a second rotating shaft 27. A second bevel gear 26 is fixedly installed at the end of the second rotating shaft 27 away from the third rotating shaft 28. The bottom end of the second bevel gear 26 is meshed with a first bevel gear 25. The first bevel gear 25 is fixedly installed at the top end of the first rotating shaft 13.

[0058] When mixing the raw materials, the rotation of the stirring shaft 6 drives the rotation of the first rotating shaft 13 through the pulley group 14. The rotation of the first rotating shaft 13 drives the rotation of the first bevel gear 25. The rotation of the first bevel gear 25 drives the rotation of the second bevel gear 26. The rotation of the second bevel gear 26 drives the rotation of the second rotating shaft 27. The rotation of the second rotating shaft 27 drives the rotation of the third rotating shaft 28 through the second connecting block 31 and the second connecting shaft 30. The rotation of the third rotating shaft 28 drives the rotation of the material control plate 29, so that the material control plate 29 rotates to control the discharge amount of the raw materials, avoiding the problem of uneven mixing of the coating caused by excessive discharge at one time, enabling the raw materials to be fully filtered and dispersed, thereby improving the quality stability of the coating.

[0059] As Figure 5 、 Figure 6 and Figure 9 shown, a second connecting shaft 30 is slidably installed on the inner wall of the third rotating shaft 28. A second connecting block 31 is fixedly installed on the outer wall of the second connecting shaft 30. The second connecting block 31 is embedded in the inner wall of the second rotating shaft 27. One end of the second connecting shaft 30 is fixedly connected to a third connecting shaft 34. The third connecting shaft 34 is rotatably installed on the inner wall of the threaded rod 35. The threaded rod 35 is embedded in the inner wall of the tank cover 3. A rotating block 36 is fixedly installed at one end of the threaded rod 35. The rotating block 36 is disposed on one side of the tank cover 3.

[0060] When mixing the raw materials, when there is no need to continue feeding, rotate the rotating block 36. The rotation of the rotating block 36 drives the rotation of the threaded rod 35. Since the threaded rod 35 is threadedly connected to the inner wall of the tank cover 3, therefore, the threaded rod 35 gradually moves away from one side of the tank cover 3. At the same time, the movement of the threaded rod 35 drives the movement of the third connecting shaft 34. The movement of the third connecting shaft 34 drives the movement of the second connecting shaft 30. The movement of the second connecting shaft 30 drives the movement of the second connecting block 31, so that the second connecting block 31 slides out of the inner wall of the second rotating shaft 27. At this time, the material control plate 29 cannot rotate when the second rotating shaft 27 rotates, thereby stopping continuous feeding.

[0061] As Figure 5 、 Figure 6 and Figure 9As shown, a third connecting block 32 is fixedly installed on the outer wall of the second connecting shaft 30. The third connecting block 32 is rotatably installed inside the tank lid 3. A limiting groove 33 is provided on one side of the third connecting block 32, and the limiting groove 33 is opened on the inner wall of the tank lid 3.

[0062] The third connecting block 32 is slidably connected with the limiting groove 33;

[0063] The second connecting block 31 is slidably connected with the third rotating shaft 28;

[0064] When the second connecting shaft 30 moves inside the inner wall of the third rotating shaft 28, the movement of the second connecting shaft 30 drives the movement of the second connecting block 31 and the third connecting block 32, causing the third connecting block 32 to slide into the third rotating shaft 28 and the third connecting block 32 to be embedded in the inner wall of the limiting groove 33. The third connecting block 32 is limited by the limiting groove 33, so that the second connecting shaft 30 cannot rotate, and thus the material control plate 29 cannot rotate, preventing the material control plate 29 from rotating due to the weight of the raw materials above, so as to improve the stability and reliability of the device.

[0065] A paint mixing method for a paint mixing device used in the production of intumescent fireproof coatings includes the following steps:

[0066] S1: When producing intumescent fireproof coatings, first put the raw materials into the feed inlet 4. After the raw materials enter the feed inlet 4, they fall to the top of the filter screen 9;

[0067] S2: Then, start the motor 8 through PLC control. When the motor 8 starts, it drives the rotation of the stirring shaft 6. When the stirring shaft 6 rotates, it drives the rotation of the first rotating shaft 13 through the transmission of the pulley group 14. The rotation of the first rotating shaft 13 drives the rotation of the first bevel gear 25. The rotation of the first bevel gear 25 drives the rotation of the second bevel gear 26. The rotation of the second bevel gear 26 drives the rotation of the second rotating shaft 27. The rotation of the second rotating shaft 27 drives the rotation of the third rotating shaft 28 through the second connecting block 31 and the second connecting shaft 30. The rotation of the third rotating shaft 28 drives the rotation of the material control plate 29, so that the material control plate 29 rotates to control the discharge amount of the raw materials;

[0068] S3: At the same time, the rotation of the first rotating shaft 13 drives the rotation of the gear 12. The rotation of the gear 12 drives the rotation of the annular gear 11. The rotation of the annular gear 11 drives the rotation of the mixing plate 10, so that the mixing plate 10 rotates on the top of the filter screen 9 to stir the raw materials above, which helps the raw materials to pass through the filter screen 9 and enter the paint mixing tank 1;

[0069] S4: Meanwhile, the rotation of the ring gear 11 drives the rotation of the first connecting shaft 19, the rotation of the first connecting shaft 19 drives the rotation of the first connecting block 20, the rotation of the first connecting block 20 drives the rotation of the protective plate 17, and the rotation of the protective plate 17 drives the rotation of the pressure plate 15, causing the pressure plate 15 to rotate together with the mixing plate 10 and always be parallel above the mixing plate 10;

[0070] S5: Meanwhile, the rotation of the first rotating shaft 13 drives the up and down movement of the moving plate 21, the movement of the moving plate 21 drives the movement of the rotating ring 18, the movement of the rotating ring 18 drives the movement of the protective plate 17, and the movement of the protective plate 17 drives the movement of the pressure plate 15, causing the pressure plate 15 to move towards one side of the mixing plate 10 to disperse the agglomerated raw materials;

[0071] S6: Meanwhile, the rotation of the stirring shaft 6 drives the rotation of the stirring paddles 7 to mix the raw materials. After mixing, the raw materials are discharged from the device through the discharge port 5.
