Description

Technical Field

[0001] The invention belongs to the technical field of coating production, and in particular relates to a dispersion kettle for coating production. Background Art

[0002] During the paint production process, film-forming substances (resins, emulsions), pigments (including extenders), solvents, and additives (auxiliaries) must be stirred and dispersed to produce a coating that meets the desired finish. When mixing these raw materials, a dispersing kettle is used. A high-speed agitator generates strong shear and centrifugal forces, evenly dispersing solid particles such as pigments and fillers in the liquid medium. This ensures thorough mixing of the various ingredients, ensuring uniformity and stability of the finished coating.

[0003] In the prior art, a narrow gap is formed between the dispersion disk and the bottom and inner wall of the kettle body.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0030] The present invention provides a dispersion kettle for coating production, such as Figures 1 to 3 As shown, it comprises a kettle body 1, a tank cover 2 is provided on the top of the kettle body 1, and a stirring device is provided on the top of the tank cover 2;

[0031] The stirring device includes a first motor 3, a rotating shaft 4, a first rotating rod 5, a driving assembly, a mounting plate 6, a connecting rod 7, a protective shell 8, a dispersion piece 9, an adjusting assembly and a stirring assembly. The output shaft of the first motor 3 is fixedly connected to the rotating shaft 4. The inner wall of the top of the rotating shaft 4 is rotatably connected to the first rotating rod 5. The top of the rotating shaft 4 and the top of the first rotating rod 5 are provided with a driving assembly. The bottom of the first rotating rod 5 is rotatably connected to two mounting plates 6. Dispersing pieces 9 are provided on the two mounting plates 6. Adjusting assemblies are provided on the dispersing pieces 9 and the mounting plates 6. The tops of the two mounting plates 6 are fixedly connected to the protective shell 8. The bottom of the rotating shaft 4 is connected to the protective shell 8 located above. Fixed connection, the upper mounting plate 6 is fixedly connected to the top of the protective shell 8 located below through the connecting rod 7, a stirring assembly is provided in the middle of the tank cover 2, a mounting bracket 10 is fixedly installed on the top of the tank cover 2, the first motor 3 is fixedly installed on the top of the mounting bracket 10, the first motor 3 is located on both sides of the stirring assembly, the stirring assembly includes a second motor 11, a stirring shaft 12 and a stirring rod 13, the second motor 11 is fixedly connected to the top of the mounting bracket 10, the output end of the second motor 11 is fixedly connected to the stirring shaft 12, the rotating shaft 4 and the stirring shaft 12 both pass through the mounting bracket 10 and the tank cover 2 and extend to the inside of the kettle body 1, and the bottom of the stirring shaft 12 is fixedly connected to the stirring rod 13.

[0032] The mounting bracket 10 facilitates the installation of the first motor 3 and the second motor 11 on the top of the tank cover 2 to improve stability. By putting materials into the kettle body 1, the second motor 11 is started to drive the stirring shaft 12 and the stirring rod 13 to rotate, so that the materials are fully mixed and a uniform mixture is initially formed. The two mounting plates 6 are conveniently connected through the connecting rod 7. The protective shell 8 can protect the mounting plate 6 and the adjustment components on the dispersion piece 9 to prevent the adjustment components from being damaged and affecting the use. According to the characteristics of different materials, the driving component and the adjustment component are used to adjust the angle of the dispersion piece 9, adjust the shear force, reduce the dispersion dead angle, and promote the exchange of upper and lower materials. For high-viscosity materials or when the upper and lower mixing needs to be strengthened, the first motor 11 is started to drive the stirring shaft 12 and the stirring rod 13 to rotate, so that the materials are fully mixed and a uniform mixture is initially formed. The first motor 3 ... mixed. The overall mixing uniformity of the material inside the kettle 1 can be effectively improved. When the first motor 3 is turned on to drive the rotating shaft 4 and the protective shell 8 to rotate, the mounting disc 6 drives the dispersion piece 9 to rotate. When the mounting disc 6 located above rotates, it drives the connecting rod 7 to rotate, so that the protective shell 8 located below drives the mounting disc 6 and the dispersion piece 9 to rotate. Then, a strong shear force is generated by the rotation of the two high-speed mounting discs 6 and the multiple dispersion pieces 9 to break up the agglomerated solid particles and realize fine dispersion of the material. After the material stirring and mixing is completed, the material is transported out of the kettle body 1 for the next process. By adjusting the angle of the dispersion piece 9, the stability and uniformity of the dispersion can be improved, thereby ensuring the stability and consistency of the product quality.

[0033] like Figures 2 to 4 As shown, the driving assembly includes a third motor 14, a movable shaft, a first gear 15 and a second gear 16. The top of the third motor 14 is fixedly connected to the inner wall of the top of the rotating shaft 4. The third motor 14 is located on one side of the first rotating rod 5. The output end of the third motor 14 is fixedly connected to the movable shaft, and the bottom end of the movable shaft is fixedly connected to the first gear 15. The second gear 16 is engaged with one side of the first gear 15, and the middle part of the second gear 16 is fixedly connected to the first rotating rod 5.

[0034] By installing the third motor 14 inside the rotating shaft 4, the third motor 14 can be protected by the rotating shaft 4. When the third motor 14 is started to drive the movable shaft and the first gear 15 to rotate, the second gear 16 drives the first rotating rod 5 to rotate along the top inner wall of the rotating shaft 4, so that the first rotating rod 5 can drive the adjusting component inside the protective shell 8 to rotate, and then adjust the angle of the dispersion piece 9 to adapt to the characteristics of different materials and change the distribution of shear force around the mounting plate 6. This can allow the material to be more evenly sheared at different positions inside the kettle body 1, thereby improving the overall dispersion uniformity and facilitating the improvement of dispersion efficiency.

[0035] like Figures 3 to 6As shown, the adjustment assembly is located inside the protective shell 8, and the adjustment assembly includes: a third gear 17, a fourth gear 18, a movable rod 19 and a connecting frame 20. The bottom of the third gear 17 is rotatably connected to the top of the mounting plate 6, the middle of the third gear 17 is fixedly connected to the first rotating rod 5, the outer side of the third gear 17 is meshed with the fourth gear 18, the middle part of the fourth gear 18 is fixedly connected to the movable rod 19, the top of the movable rod 19 is fixedly connected to the connecting frame 20, the bottom of the connecting frame 20 is rotatably connected to the top of the mounting plate 6, one side of the connecting frame 20 is fixedly connected to the dispersion piece 9, the first rotating rod 5 is rotatably connected to the middle of the protective shell 8, the dispersion piece 9 is located outside the mounting plate 6, the third gear 17 is located inside the protective shell 8, the number of dispersion pieces 9, the fourth gear 18 and the connecting frame 20 is the same, and they are distributed in a circular array in the center of the mounting plate 6.

[0036] When the first rotating rod 5 rotates, it drives the third gear 17 to rotate along the top of the mounting plate 6, so that the fourth gear 18 drives the movable rod 19 to rotate. When the movable rod 19 rotates, it drives the connecting frame 20 and the dispersion piece 9 to rotate, thereby adjusting the angle of the dispersion piece 9. The mounting frame 10 can improve the stability of the dispersion piece 9 installed on the mounting plate 6. Through the rotation of the third gear 17, multiple fourth gears 18, the connecting frame 20 and the dispersion piece 9 can be rotated at the same time, thereby adjusting the angles of multiple dispersion pieces 9 at the same time, improving the efficiency of the adjustment, and allowing the dispersion piece 9 to be adjusted according to the characteristics of different materials, thereby ensuring that the material can be evenly and effectively dispersed at various positions inside the kettle body 1, reducing quality problems caused by uneven dispersion.

[0037] like Figures 4 and 5 As shown, a movable opening 21 is opened on the outside of the protective shell 8, and the end of the connecting frame 20 away from the fourth gear 18 is arc-shaped. The arc-shaped end of the connecting frame 20 is located in the movable opening 21, and arc-shaped baffles 22 are fixedly connected on both sides thereof, and the bottom of the arc-shaped baffle 22 is rotatably connected to the top of the mounting plate 6.

[0038] Under the protection of the protective shell 8 on the adjustment component, the movable opening 21 can also drive the dispersion plate 9 to rotate by utilizing the action of the fourth gear 18, the movable rod 19 and the connecting frame 20 when the third gear 17 rotates, and adjust the angle of the dispersion plate 9. The curved side of the connecting frame 20 is connected to the curved baffle 22, and the movable opening 21 can be always blocked when the connecting frame 20 rotates to prevent the material from entering the interior of the protective shell 8 through the movable opening 21, thereby affecting the rotation of the third gear 17, the fourth gear 18 and the connecting frame 20, and affecting the stability of the angle adjustment of the dispersion plate 9.

[0039] like Figures 5 to 7As shown, an arc-shaped groove is provided on the top of the mounting plate 6, and the arc-shaped groove is located at the bottom of the connecting frame 20 and the fourth gear 18. One end of the movable rod 19 is rotatably connected to a limiting block 23, and the limiting block 23 is located in the arc-shaped groove. The number of limiting blocks 23 is the same as the number of movable rods 19. A mounting block 24 is provided between two adjacent limiting blocks 23, and the mounting block 24 is fixedly installed on the inner wall of the top end of the arc-shaped groove.

[0040] The arc groove facilitates the installation of the limiting block 23 and the limiting structure, and the fourth gear 18 and the limiting block 23 are connected by the movable rod 19. When the third gear 17 drives the fourth gear 18 to rotate, the fourth gear 18 drives the movable rod 19 to rotate along the limiting block 23. The limiting structure is conveniently installed in the arc groove through the mounting block 24, which facilitates the improvement of the firmness of the dispersion piece 9 installed on the mounting plate 6. The limiting block 23 is fixed by the limiting structure, so that the movable rod 19, the fourth gear 18, the connecting frame 20 and the dispersion piece 9 can be stably fixed on the mounting plate 6, which facilitates the improvement of the service life of the dispersion piece 9.

[0041] like Figures 7 and 8 As shown, a limiting structure is provided at the bottom of the mounting block 24, and the limiting structure is located between two adjacent limiting blocks 23. The limiting structure includes: a knob 25, a second rotating rod, a moving block 26, a pushing plate 27, a movable block 28 and a fixed block 29. The bottom end of the knob 25 is fixedly connected to the second rotating rod, and one end of the second rotating rod is threadedly connected to the moving block 26. Both sides of the moving block 26 are slidably connected to the inner wall of the arc groove, and the bottom of both ends of the moving block 26 are hinged with a pushing plate 27, and one end of the pushing plate 27 is hinged with a movable block 28. The top of the movable block 28 is fixedly connected to the fixed block 29. The knob 25 is provided at the top of the mounting block 24, and the second rotating rod passes through the mounting block 24 and is rotatably connected to the inner wall of the bottom of the arc groove. Limiting openings are opened on both sides of the limiting block 23, and the fixed block 29 is plugged into the limiting opening. The bottom of the movable block 28 is slidably connected to the inner wall of the bottom of the arc groove.

[0042] When the dispersion sheet 9 needs to be replaced, the protective shell 8 is first removed from the mounting plate 6, and the second rotating rod is driven to rotate along the bottom inner wall of the arc groove by turning the knob 25. Since the moving block 26 is threadedly connected to the second rotating rod, both sides of the moving block 26 are slidably connected to the inner wall of the arc groove. When the second rotating rod is rotated, the moving block 26 moves upward along the second rotating rod, thereby driving one end of the pushing plate 27 to deflect, and the pushing plate 27 drives the movable block 28 to move along the bottom inner wall of the arc groove, so that the movable block 28 drives the fixed block 29 to move in the direction close to the second rotating rod, and separates from the limiting mouth and no longer fixes the limiting block 23, and then moves the connecting frame 20 upward to drive the dispersion sheet 9 and the fourth gear 20. The wheel 18, the movable block 28 and the limiting block 23 move out of the arc groove, so that the limiting block 23 is no longer inserted in the arc groove, so that the dispersion piece 9 is removed for replacement, and then the new dispersion piece 9, the connecting frame 20, the fourth gear 18, the movable rod 19 and the limiting block 23 are inserted into the arc groove, and the knob 25 is rotated in the opposite direction to rotate the second rotating rod, and the movable block 26 is moved downward to drive the push plate 27 to deflect, pushing the movable block 28 and the fixed block 29 to move away from the second rotating rod, so that the fixed block 29 is plugged into the limiting port, fixing the limiting block 23, and then fixing the dispersion piece 9 on the mounting plate 6, so as to improve the stability of the dispersion piece 9, improve the uniformity of dispersion, and facilitate reuse.

[0043] Figure 1 The picture shows the complete state of the actual product. Due to the large overall structure, it is installed in two layers in the factory. Figure 9 The display part is on the second floor, which is convenient for viewing and setting the instruments on the top. Another part is on the first floor, passing through the ceiling, which is convenient for staff to operate the bottom and surrounding areas of the kettle.

[0044] Working principle:

[0045] like Figures 1 to 9As shown, when in use, when the third motor 14 is started to drive the movable shaft and the first gear 15 to rotate, the second gear 16 drives the first rotating rod 5 to rotate along the top inner wall of the rotating shaft 4. When the first rotating rod 5 rotates, it drives the third gear 17 to rotate along the top of the mounting plate 6, so that the fourth gear 18 drives the movable rod 19 to rotate. When the movable rod 19 rotates, it drives the connecting frame 20, the dispersion piece 9 and the arc baffle 22 to rotate. When the connecting frame 20 rotates, it drives the arc baffle 22 to rotate to block the movable opening 21 to prevent materials from entering the protective shell 8. Through the rotation of the third gear 17, multiple fourth gears 18, the connecting frame 20 and the dispersion piece 9 can be rotated at the same time, thereby adjusting the angles of the multiple dispersion pieces 9 at the same time and adjusting the shear force of the dispersion piece 9. Each dispersion piece 9 can adapt to the characteristics of different materials. After the angle adjustment of the dispersion piece 9 is completed, the material is first put into the kettle body 1, and the second motor 11 is started to drive the stirring shaft 12 and the stirring rod 13 to rotate, so that the material is fully mixed and a uniform mixture is initially formed. Then the first motor 3 is turned on to drive the rotating shaft 4 to rotate, so that the rotating shaft 4 drives the protective shell 8, the mounting disk 6 and the dispersion piece 9 to rotate. When the mounting disk 6 located above rotates, the connecting rod 7 is driven to rotate, so that the protective shell 8 located below drives the mounting disk 6 and the dispersion piece 9 to rotate, and then a strong shear force is generated through the rotation of the two high-speed mounting disks 6 and multiple dispersion pieces 9 to break up the agglomerated solid particles and realize fine dispersion of the material. When the material stirring and mixing is completed, the material is transported out of the kettle body 1 for the next process.

[0046] When the dispersion sheet 9 needs to be replaced, the protective shell 8 is first removed from the mounting plate 6, and the second rotating rod is driven to rotate along the bottom inner wall of the arc groove by turning the knob 25. Since the moving block 26 is threadedly connected to the second rotating rod, both sides of the moving block 26 are slidably connected to the inner wall of the arc groove. When the second rotating rod is rotated, the moving block 26 moves upward along the second rotating rod, thereby driving one end of the pushing plate 27 to deflect, and the pushing plate 27 drives the movable block 28 to move along the bottom inner wall of the arc groove, so that the movable block 28 drives the fixed block 29 to move in the direction close to the second rotating rod, and separates from the limiting opening and no longer fixes the limiting block 23, and then moves the connecting frame 20 upward. , driving the dispersion piece 9, the fourth gear 18, the movable block 28 and the limiting block 23 to move out of the arc groove, so that the limiting block 23 is no longer inserted in the arc groove, thereby removing the dispersion piece 9 for replacement, and then inserting the new dispersion piece 9, the connecting frame 20, the fourth gear 18, the movable rod 19 and the limiting block 23 into the arc groove, rotating the knob 25 in the opposite direction, so that the second rotating rod rotates, moving the movable block 26 downward, driving the push plate 27 to deflect, pushing the movable block 28 and the fixed block 29 to move in the direction away from the second rotating rod, so that the fixed block 29 is plugged into the limiting port, fixing the limiting block 23, and then fixing the dispersion piece 9 on the mounting plate 6 for continued use.

[0047] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
