Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of coating production devices, in particular to a grinding device for processing water-based nano heavy-duty anti-corrosion coatings. Background Art
[0002] Anti-corrosion coatings are liquid or solid materials that, under certain conditions, form a thin film when applied to surfaces, providing protection, decoration, or other special functions. Because early coatings were mostly based on vegetable oils, they were also called paints. Synthetic resins have largely or completely replaced vegetable oils, hence the name "coating." Anti-corrosion coatings primarily serve three functions: protection, decoration, and concealing product defects, thereby enhancing their value. The preparation of anti-corrosion coatings requires a grinding device. Existing grinding equipment relies solely on a pair of grinding rollers, resulting in low grinding efficiency and often incomplete grinding, affecting the coating's final use. Furthermore, the heating generated by the grinding rollers during grinding can cause solvent volatilization in the coating, altering the composition of the coating, potentially causing chemical changes in certain components, and changing the coating's viscosity, thus affecting the coating's quality.

[0018] See also Figure 1-Figure 3 This embodiment provides a grinding device for processing water-based nano heavy-duty anti-corrosion coatings, including a base 1, a grinding box 2 is provided on the top of the base 1, and a crushing box 3 is provided on the top of the grinding box 2.
[0019] A crushing motor 4 is mounted on the top of the crushing box 3. The output shaft of the crushing motor 4 extends vertically downward through the top of the crushing box 3 and is secured to a vertically mounted rotating shaft 5. A crushing blade 6 is mounted at the bottom of the crushing box 3. A partition 8 is mounted on one side of the top of the grinding box 2. A baffle 10 is mounted above the partition 8 and slides between the partition 8 and the top wall of the grinding box 2. A horizontally mounted electric telescopic rod 9 is secured to one side of the grinding box 2. The output shaft of the electric telescopic rod 9 extends through the side wall of the grinding box 2 and is connected to one side of the baffle 10. When the crushing box 3 is operating, the baffle 10 is positioned at the location of the discharge opening 7. After the crushing box 3 completes its operation, the baffle 10 moves horizontally toward the side of the electric telescopic rod 9, allowing material from the crushing box 3 to enter the grinding box through the discharge opening 7.
[0020] The grinding box 2 is provided with two horizontal and parallel grinding rollers 20, and roller shafts 21 are connected to both ends of the grinding roller 20. The roller shaft 21 is a tubular structure. A cooling water flow space is provided inside the grinding roller 20. The roller shafts 21 at both ends of the grinding roller 20 are connected to the cooling water flow space. The cooling water flow space can be a spiral structure space provided inside the grinding roller 20, and its two ends are respectively connected to the roller shaft 21. The roller shaft 21 is rotatably connected to the side wall of the grinding box 2. The ends of the roller shaft 21 located at the left end of the two grinding rollers 20 are respectively connected to the output pipe 29 through the output rotating connector 28. The two output pipes 29 are connected to the return pipe 31 through the junction joint 30. The return pipe 31 is connected to the water tank 32 arranged at the bottom of the base 1. The water tank 32 is connected to the water pump 34 through the input pipe 33. The water pump 34 is connected to the diversion joint 36 through the connecting pipe 35. The diversion joint 36 is connected to two water pipes 37. The ends of the two water pipes 37 are respectively connected to the roller shaft 38 at the right end through the input rotary joint 38.
[0021] Two gears 26 meshing with each other are fixed to the ends of the roller shafts 21 on the same side of the two grinding rollers 20, one of the roller shafts 21 is fixed with a driven wheel 24, a grinding motor 22 is fixed to the top of the base 1, and a driving wheel 23 is fixed to the motor shaft of the grinding motor 22, and the driving wheel 23 and the driven wheel 24 are connected through a conveyor belt 25.
[0022] The paint is first crushed and ground in the crushing box 3 by the crushing motor 4, rotating shaft 5, and crushing blade 6, and then enters the grinding box for secondary grinding. During the secondary grinding, the grinding motor 22 is in operation, and through the connection relationship between the driving wheel 23, the driven wheel 24, and the conveyor belt 25, and the meshing connection relationship between the two gears 26, it drives the grinding roller 20 to rotate and grind the paint. During the grinding process, the water pump 34 is in operation, drawing water from the water tank and flowing it through the connecting pipe, the diverter joint 36, the water pipe 37, and the input rotary joint 38 into the roller shaft 21 at the right end. The water flows through the roller shaft 21 at the right end and flows into the cooling water flow space inside the grinding roller. Then, through the roller shaft at the left end 21, it flows through the output pipe 29, the junction 30, the return pipe 31, and finally enters the water tank 32. This cycle is repeated to cool the grinding roller 20 to prevent the heating of the grinding roller from affecting the quality of the paint.
[0023] Based on the fact that paint accumulates at a fixed position during grinding in the prior art, thus affecting the efficiency and quality of grinding, this embodiment provides a screed box 12 and an upper guide rod 11 above the grinding roller 20. The upper guide rod 11 is a cylindrical structure. The upper guide rod 11 is fixed to the side wall of the grinding box 2; the screed box 12 is a box with an open top; the upper guide rod 11 passes through the top of the screed box 12 and is slidably connected to the screed box 12; a screw 13 and a lower guide rod 17 are provided at the front and rear sides below the bottom of the screed box 12, respectively. The screws 13 and the lower guide rod 17 are parallel to the upper guide rod 11. The screws 14 threadedly connected to the screw 13 and the slider 16 slidably connected to the lower guide rod 17 are provided at the front and rear sides of the bottom of the screed box 12, respectively. The screw 13 is driven by the screed motor 5.
[0024] The bottom of the screed box 12 has a conical longitudinal cross-section, with a feed port 18 located at the center of the conical bottom. When the screed motor 5 is activated, the screed box 12 moves back and forth along the screw 13, directing the paint from the feed port 18 toward the grinding position of the grinding roller and distributing the paint back and forth along the length of the grinding roller. This prevents paint from accumulating at a fixed position on the grinding roller and improves grinding efficiency. During operation, the screed box 12 moves back and forth, ensuring that the top opening of the screed box 12 is aligned with the feed port 7.
