Description

Technical Field

[0001] This invention belongs to the field of electrophoretic paint processing technology, specifically a high-efficiency dispersion system for the production of surface-treated titanium dioxide electrophoretic paint. Background Technology

[0002] Electrophoretic coating, as an advanced coating technology, has been widely used in various industries such as automobiles, home appliances, and hardware due to its advantages such as good film uniformity, high coating efficiency, environmental friendliness, and excellent corrosion resistance. To meet the market demand for white, high-coverage coatings, titanium dioxide (titanium dioxide) is added as the main white pigment to the electrophoretic coating formula, forming titanium dioxide electrophoretic coating. Titanium dioxide, with its excellent hiding power, high whiteness, and good weather resistance, can give the electrophoretic coating a bright white appearance and effectively improve the decorative and protective properties of the film. However, as a fine powder with a high specific surface area, titanium dioxide has a serious tendency to agglomerate during the production and processing of electrophoretic coatings. If it is not sufficiently dispersed, these undispersed titanium dioxide agglomerates will lead to a series of quality problems in the final film, such as insufficient hiding power, poor gloss, uneven film, grainy surface, and decreased coating stability, seriously affecting the overall performance of the electrophoretic coating.

[0003] The existing authorized patent (publication number: CN221062371U) discloses a high-efficiency disperser for electrophoretic paint production. This disperser achieves dispersion by simply driving the dispersion disc with rotating rods of different directions. This dispersion process has a simple structure, poor dispersion effect, and long processing time. Therefore, improvements are needed to address the above problems. Summary of the Invention

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] (1) This dispersion system has a multi-functional dispersion processing structure. This multi-functional dispersion processing structure realizes the efficient dispersion processing operation of titanium dioxide electrophoretic paint through revolution, rotation, reciprocating movement up and down and rotation in different directions at the upper and lower ends, thereby effectively ensuring the effect and quality of dispersion processing, and improving the efficiency and speed of titanium dioxide electrophoretic paint processing.

[0014] (2) By starting the motor, the connecting shaft and the connecting plate are driven to rotate. The rotation of the connecting plate will drive the two upper stirring shafts, the two lower stirring shafts and the dispersing plate to rotate in circles, so that the dispersing plates on the upper stirring shafts and the lower stirring shafts will revolve and stir and disperse.

[0015] (3) When the connecting plate drives the two upper stirring shafts, the two lower stirring shafts and the dispersing plate to rotate in a circle, it will drive the two rollers to roll up and down in the continuous wave-shaped groove. The up and down rolling of the two rollers will drive the lifting slide plate to slide up and down on the slide rod through the mounting shaft. The up and down sliding of the two lifting slide plates will drive the two upper stirring shafts to slide up and down continuously through the connecting block. The up and down sliding of the two upper stirring shafts will drive the two lower stirring shafts and the dispersing plate to slide up and down synchronously. Thus, the rotating upper and lower stirring shafts can perform up and down stirring and dispersing operations through the dispersing plate.

[0016] (4) When the connecting plate drives the two upper agitator shafts and the two lower agitator shafts to rotate in a circle, it will drive the two transmission gears to roll on the surface of the toothed ring sleeve. At the same time, when the lifting slide plate slides up and down, it will cause the two transmission gears to slide on the surface of the toothed ring sleeve and maintain effective meshing and rolling rotation. The rolling rotation of the two transmission gears will drive the two transmission shafts to rotate. The transmission shaft will drive the bevel gear four to rotate and drive the bevel gear three to rotate. The rotation of the bevel gear three will drive the adjusting shaft and the large bevel gear to rotate. The rotation of the large bevel gear will accelerate the transmission rotation of the bevel gear two and the bevel gear one. The rotation of the bevel gear one and the bevel gear two will drive the upper agitator shaft and the lower agitator shaft to rotate in different directions for adjustment. The upper agitator shaft and the lower agitator shaft rotating in different directions will drive the dispersion plate on them to perform agitation and dispersion operations in different directions.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0027] Example 1, by Figures 1 to 6 The present invention includes a base 1, a mixing tank 2 is placed on the top of the base 1, the top of the base 1 is provided with a placement groove for placing the mixing tank 2, a discharge pipe is installed at the bottom of the mixing tank 2, and a control valve is installed on the discharge pipe, so as to stably place the mixing tank 2 and enable the mixing tank 2 to effectively perform the discharge operation.

[0028] An L-shaped fixing plate 3 is fixedly installed on the top of the base 1. A telescopic cylinder 4 is installed through the upper part of the L-shaped fixing plate 3. The telescopic cylinder 4 is located directly above the middle of the mixing tank 2. An installation plate 5 is installed on the telescopic end of the telescopic cylinder 4. A connecting frame 29 is fixedly installed on the top of the installation plate 5. The middle part of the top of the connecting frame 29 is fixedly connected to the telescopic end of the telescopic cylinder 4. Two connecting arms 30 are rotatably connected to both sides of the top of the installation plate 5. Rotating arms 31 are rotatably connected to the top of the four connecting arms 30. The tops of the four rotating arms 31 are rotatably connected to the top of the inner side of the L-shaped fixing plate 3. This allows for stable and effective lifting and lowering adjustment of the installation plate 5, and enables the components under the installation plate 5 to rotate and disperse stably and effectively.

[0029] A motor 6 is installed in the middle of the top of the mounting plate 5. A round tube sleeve 7 is fixedly installed at the bottom of the mounting plate 5. A connecting plate 8 connected to the motor 6 is installed at the bottom of the round tube sleeve 7. Two upper stirring shafts 9 are symmetrically and movably installed through the connecting plate 8. The upper stirring shafts 9 are both located inside the mixing tank 2. A lower stirring shaft 10 is rotatably installed through the middle of the two upper stirring shafts 9. A dispersing plate 11 is fixedly installed at equal distances on the lower part of the surfaces of the two stirring shafts 9 and the two lower stirring shafts 10.

[0030] This dispersion system features a multi-functional dispersion processing structure. This structure achieves efficient dispersion of titanium dioxide electrophoretic paint through revolution, rotation, reciprocating movement, and rotation in different directions at the upper and lower ends. This effectively ensures the dispersion effect and quality, and improves the efficiency and speed of titanium dioxide electrophoretic paint processing. At the same time, this multi-functional dispersion processing structure is simple in design, convenient to use, and provides stable and reliable dispersion operation. Its performance meets the dispersion requirements of titanium dioxide electrophoretic paint production and processing.

[0031] In Example 2, based on Example 1, a connecting shaft 12 located inside the cylindrical sleeve 7 is rotatably mounted in the middle of the mounting plate 5. The top of the connecting shaft 12 is fixedly connected to the output end of the motor 6, and the bottom of the connecting shaft 12 is fixedly connected to the middle of the top of the connecting disk 8. A number of balls that roll in contact with the top of the connecting disk 8 are installed at equal intervals in a ring at the bottom of the cylindrical sleeve 7, so that the connecting disk 8 can drive the upper stirring shaft 9, the lower stirring shaft 10 and the dispersing disk 11 to revolve and perform dispersion operations.

[0032] The starting motor 6 drives the connecting shaft 12 and the connecting disk 8 to rotate. The rotation of the connecting disk 8 will drive the two upper stirring shafts 9, the two lower stirring shafts 10 and the dispersing disk 11 to rotate in a circle, so that the dispersing disk 11 on the upper stirring shafts 9 and the lower stirring shafts 10 will perform a revolution stirring and dispersing operation.

[0033] In Example 3, based on Example 1, two pairs of sliding rods 13 are symmetrically fixedly installed on the top of the connecting plate 8. Each pair of sliding rods 13 is equipped with a lifting slide plate 14, and each lifting slide plate 14 has two symmetrically opened vertical through holes 15. The sliding rods 13 are inserted into the interior of the vertical through holes 15. Connecting blocks 16 are fixedly installed on the lower part of the opposite side of the two lifting slide plates 14. The upper parts of the two upper stirring shafts 9 are rotatably connected to the two connecting blocks 16 through bearings, so as to effectively install the upper stirring shafts 9.

[0034] Two lifting slide plates 14 are fixedly mounted with mounting shafts 21 on the middle of opposite sides. Rollers 22 are fixedly mounted on opposite ends of the two mounting shafts 21. A continuous wave-shaped groove 23 is opened on the lower part of the surface of the round tube sleeve 7. The two rollers 22 are installed inside the continuous wave-shaped groove 23, so as to effectively drive the two upper stirring shafts 9 and the two lower stirring shafts 10 to continuously move up and down and adjust.

[0035] When the connecting plate 8 drives the two upper stirring shafts 9, the two lower stirring shafts 10, and the dispersing plate 11 to rotate in a circle, it will drive the two rollers 22 to roll up and down reciprocally inside the continuous wave-shaped groove 23. The up and down reciprocating rolling movement of the two rollers 22 will drive the lifting slide plate 14 to slide up and down on the slide rod 13 through the mounting shaft 21. The up and down reciprocating sliding movement of the two lifting slide plates 14 will drive the two upper stirring shafts 9 to continuously slide up and down through the connecting block 16. The up and down reciprocating sliding movement of the two upper stirring shafts 9 will drive the two lower stirring shafts 10 and the dispersing plate 11 to slide up and down synchronously. Thus, the rotating upper stirring shafts 9 and lower stirring shafts 10 can perform up and down stirring and dispersing operations through the dispersing plate 11.

[0036] In Example 4, based on Example 3, bevel gear 17 is fixedly installed on the upper part of both upper agitator shafts 9, and bevel gear 28 is fixedly installed on the top of both lower agitator shafts 10. Bevel gear 28 is located directly above bevel gear 17. Adjusting shaft 19 is rotatably installed through the middle of both connecting blocks 16. Large bevel gear 20 is fixedly installed on the opposite ends of the two adjusting shafts 19. The large bevel gear 20 meshes with the adjacent bevel gear 17 and bevel gear 28.

[0037] Both adjusting shafts 19 are fixedly mounted with bevel gears 24 at their opposite ends. Both lifting slides 14 are rotatably mounted with drive shafts 25 on their upper opposite sides. Both drive shafts 25 are fixedly mounted with bevel gears 26 at their bottoms, which mesh with bevel gears 24. Both drive shafts 25 are fixedly mounted with drive gears 27 at their tops. Both cylindrical sleeves 7 are fixedly mounted with toothed rings 28 on their upper surfaces. Both drive gears 27 mesh with toothed rings 28, thereby effectively driving the upper stirring shaft 9 and the lower stirring shaft 10 to rotate in different directions.

[0038] When the connecting disc 8 drives the two upper stirring shafts 9 and the two lower stirring shafts 10 to rotate in a circle, it will cause the two transmission gears 27 to roll on the surface of the toothed ring sleeve 28. At the same time, when the lifting slide plate 14 slides up and down, it will cause the two transmission gears 27 to slide on the surface of the toothed ring sleeve 28 and maintain effective meshing and rolling rotation. The rolling rotation of the two transmission gears 27 will drive the two transmission shafts 25 to rotate. The transmission shafts 25 will drive the fourth bevel gear 26 to rotate and drive the third bevel gear 24 to rotate. The rotation of the third bevel gear 24 will drive the adjusting shaft 19 and the large bevel gear 20 to rotate. The rotation of the large bevel gear 20 will accelerate the rotation of the second bevel gear 18 and the first bevel gear 17. The rotation of the first bevel gear 17 and the second bevel gear 18 will drive the upper stirring shafts 9 and the lower stirring shafts 10 to rotate in different directions for adjustment. The upper stirring shafts 9 and the lower stirring shafts 10 rotating in different directions will drive the dispersing discs 11 on them to perform stirring and dispersing operations in different directions.

[0039] Ultimately, the dispersing disk 11 revolves, rotates, moves up and down reciprocally, and rotates in different directions at its upper and lower ends, thereby enabling the dispersing disk 11 to perform efficient dispersion processing of titanium dioxide electrophoretic paint, effectively ensuring the effect and quality of dispersion processing, and improving processing efficiency and speed.
