Description

Technical Field

[0001] This utility model relates to the field of coating dispersion technology, specifically a dispersion machine for preparing modified coatings. Background Technology

[0002] Dispersants are used in the modification and preparation of coatings. A disperser is a highly efficient device specifically designed for pulverizing, dispersing, emulsifying, and mixing coating raw materials during the coating preparation process. These dispersers are typically designed for slurry-like liquid raw materials of varying viscosities to ensure that the coating raw materials are uniformly and stably dispersed in the solvent, thereby achieving ideal coating performance. They play a crucial role in the modification and preparation of coatings.

[0003] According to the high-speed disperser for preparing modified polyester roller coatings with application number CN202222565068.7, this solution solves the problem that the polyester roller coating cannot be fully and uniformly dispersed and stirred, and that it is inconvenient to install and disassemble the whole unit before and after use, and it is also inconvenient to clean and maintain the dispersion components, which leads to a significant reduction in the dispersion efficiency and practicality of the high-speed disperser.

[0004] However, the following problems still exist in actual use:

[0005] (1) When dispersing coatings, the dispersion operation is carried out by using only the dispersion inclined plate and the arc-shaped dispersion blade. However, when dealing with coatings of different viscosities, the height of the dispersion component is fixed and cannot be flexibly adjusted, resulting in poor dispersion effect for high viscosity coatings. It is difficult to achieve sufficient shearing and mixing. Furthermore, for processes that require layered dispersion, it is impossible to achieve layer-by-layer dispersion by raising and lowering the dispersion component, which limits the applicability and dispersion efficiency of the equipment.

[0006] (2) When in use, the dispersing cylinder is placed directly on the base of the disperser. When the dispersing cylinder is running at high speed, due to the lack of a reliable limiting and fixing structure, it is easy to shift its position due to centrifugal force, resulting in uneven gap between the dispersing components and the cylinder wall, affecting the dispersion effect of the coating. The shaking of the dispersing cylinder may also cause equipment vibration, increase mechanical wear, reduce the service life of the equipment, and may even cause safety hazards, which will reduce the safety of operation in reality.

[0007] Therefore, this utility model introduces a dispersant for the preparation of modified coatings. Utility Model Content

[0010] Preferably, a limiting mechanism is provided on both sides of the upper surface of the base. The limiting mechanism includes a bidirectional screw, a turning block, a threaded moving block, a sliding block, and a limiting plate. The outer surface of the bidirectional screw is rotatably installed with the interior of the base. The right side of the turning block is fixedly connected to one end of the bidirectional screw. The interior of the bottom end of the threaded moving block is threadedly connected to the outer surface of the bidirectional screw. The outer surface of the sliding block is slidably connected to the inner wall of the threaded moving block. The left side of the limiting plate is fixedly installed with the right side of the sliding block.

[0011] Preferably, the front of the toothed plate is attached to the back of the support plate, and rectangular plates are fixedly installed on both sides of the toothed plate.

[0012] Preferably, a rectangular groove is provided on the back of the support plate, and the inner wall of the rectangular groove is slidably connected to the outer surface of one end of the front of the rectangular plate.

[0013] Preferably, T-shaped brackets are fixedly installed on both sides of the toothed plate, and a leak-proof ring is fixedly installed on the front of the T-shaped brackets.

[0014] Preferably, the threaded moving block has a threaded groove inside, the sliding block has a threaded groove inside, and a hand-tightening screw is threaded into the threaded groove.

[0015] Preferably, a dispersion cylinder is placed on the upper surface of the base, the outer surface of the dispersion cylinder abuts against the right side of the limiting plate, the inner wall of the dispersion cylinder is in contact with one side of the dispersion blade, and the outer surface of the dispersion cylinder is in contact with the inner wall of the leak-proof ring.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This type of disperser for preparing modified coatings, through the use of a servo motor, gears, toothed plates, connecting plates, a variable speed motor, and dispersing blades, can perform lifting and dispersing within the dispersing cylinder during coating dispersion preparation, thereby improving the dispersion range. The use of rectangular plates and grooves ensures the stability of the toothed plates as they move along the back of the dispersing cylinder. The use of a T-shaped frame and a leak-proof ring allows for synchronized lifting and dispersing operations, preventing coating from splashing out from the edge of the dispersing cylinder, thus avoiding waste and increased production costs. This solves the problem of lifting and dispersing during coating dispersion, achieving a wider dispersion range, improving the equipment's flexibility, and adapting to the dispersion of different coatings, further enhancing its applicability and dispersion efficiency.

[0018] 2. This type of disperser for preparing modified coatings, through the use of a bidirectional screw, a turning block, a threaded moving block, a sliding block, and a limiting plate, can limit and fix both sides of the dispersion cylinder placed on the upper surface of the base, achieving a safer and more stable effect during dispersion. The use of threaded grooves and hand-tightening screws allows for adjustment of the height of the limiting plate, thereby changing the height at which the dispersion cylinder is fixed, improving the stability of the dispersion cylinder during use, and thus solving the problem of how to limit and fix the dispersion cylinder. This prevents the dispersion cylinder from shaking during coating dispersion, avoids uneven dispersion, reduces equipment vibration, extends equipment lifespan, and improves safety during use.

[0026] Please see Figure 4Limiting mechanisms 23 are provided on both sides of the upper surface of the base 1. Each limiting mechanism 23 includes a bidirectional screw 15, a turning block 16, a threaded moving block 17, a sliding block 18, and a limiting plate 19. The outer surface of the bidirectional screw 15 is rotatably mounted to the interior of the base 1. The right side of the turning block 16 is fixedly connected to one end of the bidirectional screw 15. The interior of the bottom end of the threaded moving block 17 is threadedly connected to the outer surface of the bidirectional screw 15. The outer surface of the sliding block 18 is slidably connected to the inner wall of the threaded moving block 17. The left side of the limiting plate 19 is connected to the sliding block... The right side of the 18 is fixedly installed. The threaded moving block 17 has a threaded groove 20 inside, and the sliding block 18 has a threaded groove 20 inside. The threaded groove 20 is connected to a hand screw 21. Through the use of the bidirectional screw 15, the screwing block 16, the threaded moving block 17, the sliding block 18, the limiting plate 19, and the threaded groove 20, the problem of shaking of the dispersion cylinder 2 when dispersing the coating can be solved, avoiding uneven dispersion, reducing equipment vibration, improving equipment service life, and improving safety during use.

[0027] Please see Figure 1 and Figure 2 A dispersion cylinder 2 is placed on the upper surface of the base 1. The outer surface of the dispersion cylinder 2 abuts against the right side of the limiting plate 19. The inner wall of the dispersion cylinder 2 is attached to one side of the dispersion blade 10, and the outer surface of the dispersion cylinder 2 is attached to the inner wall of the leak-proof ring 14. Through the connection between the dispersion cylinder 2 and each component, the stability of the dispersion cylinder 2 during use can be ensured, the effect of scraping the inner wall of the dispersion cylinder 2 when dispersing the coating can be ensured, and the problem of coating leakage inside the dispersion cylinder 2 can be avoided.

[0028] Working principle: When using the dispersion cylinder 2 for limiting and fixing, the dispersion cylinder 2 can be placed on the upper surface of the base 1 first. Then, the outer surface of the sliding block 18 slides on the inner wall of the threaded moving block 17. According to the actual limiting and fixing requirements, the sliding block 18 drives the position of the limiting plate 19 to rise and fall. After the height of the limiting plate 19 is changed, the threaded groove 20 opened inside the sliding block 18 and the threaded moving block 17 allows the hand screw 21 to be installed inside the threaded groove 20, limiting the position of the limiting plate 19 after the height change. Finally, by turning the turning block 16, the double-direction screw 15 fixedly installed on the right side of the turning block 16 can be driven to rotate inside the base 1. This drives the threaded connection of the double-direction screw 15 to the threaded moving block 17 to move to the opposite side, allowing the limiting plate 19 to limit and fix the outer surface of the dispersion cylinder 2.

[0029] During the dispersion operation, paint can be placed inside the dispersion cylinder 2 first. Then, through the power of the servo motor 5, the gear 6 fixedly mounted on the outer surface of one end of the output shaft of the servo motor 5 can be rotated. When the gear 6 rotates, the rectangular groove 12 opened on the back of the support plate 3 and the rectangular plates 11 fixedly mounted on both sides of the toothed plate 7 sliding on the inner wall of the rectangular groove 12 can drive the position of the gear 6 meshing with the toothed plate 7 to rise and fall on the back of the support plate 3. At the same time as the position of the toothed plate 7 rises and falls, the position of the connecting plate 8 can rise and fall synchronously. Then, through the power of the variable speed motor 9, the dispersion blade 10 can be driven to disperse the paint inside the dispersion cylinder 2, which can be dispersed by lifting and lowering. When the position of the dispersion blade 10 rises and falls, through the connection of the T-shaped frame 13 fixedly mounted on both sides of the toothed plate 7, the position of the anti-leakage ring 14 can be raised and lowered synchronously on the outer surface of the dispersion cylinder 2 to prevent the paint from overflowing during the lifting and lowering dispersion.
