Description

Technical Field

[0001] The utility model relates to the technical field of pearlescent glass flake grinding, in particular to a glass flake grinding device. Background Art

[0002] Flake glass powder is a powder material widely used in the fields of industry and cosmetics. It has unique lamellar structure, excellent surface flatness, high reflectivity and other characteristics. After depositing high refractive index nano metal oxide on its surface, it can produce diamond-like purity and brilliance. It can be widely used in various cosmetics, car paints, plastics and high-end decorative materials, thus giving the product a strong visual effect.

[0003] When preparing glass-based pearlescent pigments, the glass powder needs to be ground and graded according to demand so that its particle size meets the usage requirements. The existing grinding device uses a rigid grinding wheel in a closed space to repeatedly grind and crush glass flakes to refine the powder particle size. Since the rigid grinding wheel easily scratches the glass surface and destroys the surface flatness of the glass flakes, the subsequent nanoparticle surface deposition process produces diffuse reflection due to the surface unevenness, resulting in a significant impact on the color purity and brightness of the pearlescent.

Therefore, the terms describing the positional relationship in the figures are only used for illustrative purposes and cannot be understood as limitations on the present invention. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0036] like Figure 1-2 As shown, the present application provides a glass flake grinding device, including a grinding cylinder 10, a driving assembly and a grinding block 31. The grinding cylinder 10 is used to contain glass powder and grinding media. The driving assembly is used to drive the grinding block 31 to rotate circumferentially in the grinding cylinder 10. The grinding block 31 is used to stir the glass during the movement. The top of the grinding cylinder 10 is open. A flexible layer 32 is provided on the surface of the grinding block 31. In the present application, the purpose of providing the flexible layer 32 is to prevent the glass surface from being scratched during the movement of the grinding block 31, so as to ensure the deposition effect of nanoparticles.

[0037] A mounting rod 33 is provided on one side of the grinding block 31. The driving assembly includes a motor 21 and a rotating shaft 22. A cylinder cover 11 is provided at the open end of the grinding cylinder 10. The motor 21 is arranged on the cylinder cover 11, and one end of the rotating shaft 22 is connected to the output end of the motor 21. A mounting hole for the mounting rod 33 to pass through is provided on the rotating shaft 22. The free end of the mounting rod 33 passes through the mounting hole. When the motor 21 drives the rotating shaft 22 to rotate, it can drive the mounting rod 33 and the grinding block 31 to rotate around the rotating shaft 22. A flexible layer 32 is also provided at the free end of the mounting rod 33. The flexible layer 32 can preferably be a nylon structure or a plastic. In the present application, rubber is used as the flexible layer 32. In the present application, the motor 21 and the rotating shaft 22 are used as the driving assembly for driving the grinding block 31. In actual use, the motor can also be used to cooperate with the first bevel gear structure of the bevel to drive the grinding block 31. In the present application, the motor and the rotating shaft are directly used, the structure is simple, and it is easy to install. During the rotation of the grinding block 31 and the mounting rod 33 , the glass flakes and the grinding media can be stirred, so that the glass flakes and the grinding media are fully in contact with each other, and the glass flakes are ground.

[0038] Preferably, in order to improve the stirring efficiency of the grinding block 31 and the mounting rod 33, two or more sets of mounting rods 33 and grinding blocks 31 can be arranged on the rotating shaft 22. In the present application, a scraper 34 is fixedly arranged at one end of the rotating shaft 22 away from the motor 21. The scrapers 34 are evenly or unevenly distributed along the axial direction of the rotating shaft 22. The scrapers 34 can stir the glass powder at the bottom of the grinding cylinder 10 to improve the grinding effect.

[0039] In order to improve the stirring efficiency of the grinding block 31, in the present application, a structure for driving the grinding block 31 near the bottom of the grinding cylinder 10 to rotate is provided. Specifically, the mounting rod 33 is rotatably connected to the rotating shaft 22. A first bevel gear 35 is provided on the circumference of the mounting rod 33. A second bevel gear 36 is provided at the bottom of the grinding cylinder 10. During the rotation of the mounting rod 33 around the rotating shaft 22, the first bevel gear 35 is always engaged with the second bevel gear 36. In this way, the mounting rod 33 and the grinding block 31 rotate themselves during the revolution around the rotating shaft 22, thereby improving the stirring effect.

[0040] The existing grinding device usually needs to dump all the glass powder out after grinding the glass powder, and it is impossible to take out the glass powder that has been ground to the required size during the grinding process. This will cause the glass powder that has been ground to continue grinding as a whole, increasing the probability of scratching the glass surface. In view of this problem, improvements have also been made in this application. Specifically, Figure 2The bottom of the grinding cylinder 10 is provided with a filter hole 12. The diameter of the filter hole 12 matches the size of the required grinding wheel powder. An output component 40 is provided below the grinding cylinder 10. The output component 40 is used to output the glass powder falling out of the filter hole 12. The output component can be a conveyor belt, or a vibrating conveyor belt, etc.

[0041] like Figure 3 The device also includes a bracket 14, which is used to install the grinding cylinder 10 above the output component. In order to prevent the glass powder from falling outside the output component 40, the present application provides a funnel 13 at the bottom of the grinding cylinder 10, and the funnel 13 is used to guide the glass powder to fall onto the output component.

[0042] The method of using the utility model is as follows:

[0043] When the motor 21 drives the rotating shaft 22 to rotate, it can drive the mounting rod 33 and the grinding block 31 to rotate synchronously. During this process, the grinding block 31 and the mounting rod 33 will stir the glass powder and the grinding medium in the grinding cylinder 10 to make them fully contact and rub. The flexible layer 32 on the surface of the grinding block 31 and the mounting rod 33 can ensure that the glass surface is not scratched during the stirring process of the grinding block 31 and the mounting rod 33. The grinding block 31 and the mounting rod 33 will also rotate during the rotation process, thereby improving the stirring efficiency.

[0044] The above embodiments are only used to illustrate the technical solution of the utility model and are not intended to limit it. Although the utility model is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
