Description

Technical Field

[0001] This utility model relates to the field of mineral polishing technology, and in particular to a polishing device for non-metallic mineral products. Background Art

[0002] Non-metallic mineral products are various products processed from non-metallic minerals as the main raw materials, including asbestos, mica, gypsum, talc, and graphite. These minerals have different properties; for example, asbestos has high heat resistance and chemical stability, mica is insulating, heat-resistant, and corrosion-resistant, gypsum is used in construction and medicine, talc has lubricating, fire-resistant, and insulating properties, and graphite has good electrical and thermal conductivity and lubrication. Grinding equipment is mainly used to remove surface imperfections. During production or use, products may develop scratches, dents, burrs, and other defects. Grinding removes these uneven areas, making the product surface smoother and cleaner, thus improving the overall aesthetics of the product.

[0003] Existing non-metallic mineral product grinding equipment suffers from cumbersome grinding head replacement when tools are unavailable. When a worn grinding head needs replacement, the inability to do so quickly results in lengthy disassembly and reassembly procedures, consuming considerable time. This leads to prolonged equipment downtime, reducing the actual time spent grinding non-metallic mineral products, thus lowering overall work efficiency and impacting production schedules. In continuous production scenarios, the inability to quickly change grinding heads disrupts production continuity. Frequent downtime for grinding head replacement interrupts the production process, affecting upstream and downstream processes, hindering efficient assembly line operations, and negatively impacting large-scale production and stable supply for enterprises. Therefore, this paper proposes a non-metallic mineral product grinding device to address these issues. Utility Model Content

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 , Figure 3This utility model provides an embodiment of a non-metallic mineral product grinding device, comprising a base plate 1. The base plate 1 is made of heavy-duty cast iron, whose excellent hardness and stability can steadily support the weight of the entire device, ensuring no shaking during operation. A robotic arm 10 is fixedly connected to the top of the base plate 1. The robotic arm 10 is made of high-strength aluminum alloy, ensuring both lightness and flexibility while possessing sufficient strength to withstand the weight of the grinding disc 17 and various forces during operation. It can move precisely in multiple directions, accurately positioning the grinding disc 17 at the optimal grinding position for the non-metallic mineral product, thereby improving grinding accuracy and efficiency.

[0032] The other end of the robotic arm 10 is fixedly connected to a limiting shell 11. The limiting shell 11 is made of sturdy steel and has a smooth and flat internal surface after precision machining, providing good conditions for the sliding of the ball bearings 12. It is firmly connected to the robotic arm 10 to ensure that it does not loosen or fall off during grinding. Multiple ball bearings 12 are slidably connected inside the limiting shell 11. The ball bearings 12 are made of high-hardness stainless steel and are round and smooth. They roll freely during the insertion and removal of the connecting post 16, reducing frictional resistance and making the replacement of the grinding disc 17 easy and quick. The connecting post 16 is slidably connected to the inner side of the multiple ball bearings 12. The connecting post 16 is made of high-quality alloy steel and has extremely high strength and toughness. It is firmly connected to the grinding disc 17 and can withstand huge centrifugal force and impact force during high-speed rotation grinding without deformation or damage.

[0033] A limiting ring 14 is slidably connected to the outer side of the ball bearing 12. The limiting ring 14 is made of highly elastic rubber material, which tightly fits the ball bearing 12 to effectively prevent it from loosening accidentally during operation, ensuring connection stability and reliability. A limiting ring 13 is fixedly connected to the outer side of the limiting ring 14. The limiting ring 13 is made of stainless steel with a finely treated, smooth surface free of burrs, allowing operators to easily pull it to quickly change the grinding disc 17. A spring 15 is fixedly connected inside the limiting ring 13. The spring 15 is made of high-strength spring steel, which has good elasticity and durability. Under normal conditions, it keeps the limiting ring 14 tightly pressing the ball bearing 12 to ensure that the connecting post 16 is always stably connected. A slot is opened on the outer side of the connecting post 16. The slot is precisely designed to perfectly match the ball bearing 12, enhancing the connection firmness and preventing the grinding disc 17 from loosening or falling off during operation.

[0034] The other end of the connecting column 16 is fixedly connected to a grinding disc 17. The grinding disc 17 can be made of different materials and grits, such as silicon carbide and alumina, to efficiently grind non-metallic mineral products until their surfaces are smooth as a mirror. The top of the base plate 1 is fixedly connected to a worktable 2. The worktable 2 is welded from thick steel plates, making it sturdy and durable enough to withstand the weight of the mineral products and various forces during grinding. The surface is treated with rust prevention to prevent rusting and extend its service life.

[0035] Reference Figure 2 , Figure 4Two cabinet doors 20 are rotatably connected to one side of the workbench 2. These doors are made of the same steel plate as the workbench 2, and when closed, they fit tightly against the workbench 2, effectively protecting internal components from dust and debris and facilitating maintenance and repair. Multiple holes are provided on the top of the workbench 2; their carefully designed layout allows the internal suction components to better extract grinding powder, maintaining a clean working environment and reducing dust hazards to operators. A powder suction component, including a blower 19, is fixedly connected inside the workbench 2. The blower 19 is a high-efficiency, energy-saving model with powerful suction, quickly and effectively drawing powder into the workbench 2, reducing dust pollution.

[0036] The workbench 2 has two movable filter barrels 18 inside. These filter barrels 18 use high-efficiency filter materials such as activated carbon and non-woven fabric to effectively filter powder and prevent it from entering the atmosphere, protecting the environment. The top of the workbench 2 is fixedly connected to a drive assembly containing the driving parts, including a housing 3. The housing 3 is made of robust aluminum alloy and anodized, providing excellent corrosion and wear resistance, ensuring reliable protection for internal components such as the motor 4. The bottom of the housing 3 is fixedly connected to the top of the workbench 2 using high-strength bolts to ensure the stability and reliability of the drive assembly for fixing and moving mineral products.

[0037] A motor 4 is fixedly connected inside the outer casing 3. The motor 4 is a high-quality motor with appropriate power, providing efficient power output and stable performance to ensure sufficient power for the rotating plate 5, guaranteeing stable operation of fixing the mineral products. The rotating plate 5 is fixedly connected to the drive end of the motor 4. The rotating plate 5 is made of high-strength steel plate, precision-machined to have a smooth and flat surface, capable of withstanding the forces generated during connection and stably driving the connecting plate 6. Connecting plates 6 are rotatably connected to both sides of the rotating plate 5. The connecting plates 6 are made of sturdy steel with good strength and toughness, capable of transmitting power from the motor 4 to move the clamping plate 9.

[0038] Both connecting plates 6 are fixedly connected to the top of connecting posts 7. Connecting posts 7 are made of high-strength alloy steel and undergo heat treatment to achieve extremely high strength and hardness, firmly connecting connecting blocks 8 and clamping plates 9. They withstand significant forces without deformation during the fixing of mineral products. Connecting blocks 8 are fixedly connected to the outer side of connecting posts 7. Connecting blocks 8 are made of cast iron and precision-cast, possessing good strength and stability, and reliably connecting to clamping plates 9. Clamping plates 9 are fixedly connected to one side of connecting blocks 8. Clamping plates 9 are made of elastic rubber with a non-slip surface treatment, better clamping mineral products without causing damage.

[0039] The clamping plate 9 is slidably connected to the top of the outer casing 3. The smooth surface of the groove on the top of the outer casing 3 is finely machined, allowing the clamping plate 9 to move more smoothly and improving the efficiency of fixing mineral products. The top of the outer casing 3 has a groove, and the width and depth of the groove are reasonably designed to perfectly match the clamping plate 9, ensuring that the clamping plate 9 does not wobble or shift during movement. The outer side of the connecting column 7 is slidably connected to the inside of the outer casing 3. High-precision guide rails and sliders are used to ensure that the connecting column 7 moves stably during operation, enabling accurate adjustment of the clamping plate 9.

[0040] Working principle: When the worker needs to polish the mineral product, the mineral product can be placed on the top of the outer shell 3, and then the motor 4 can be started to drive the rotating plate 5. The two sides of the rotating plate 5 are rotatably connected to the connecting plate 6, and the top of the connecting plate 6 is fixedly connected to the connecting column 7. The outer side of the connecting column 7 is fixedly connected to the connecting block 8, and the outer side of the connecting block 8 is fixedly connected to the clamping plate 9. When the rotating plate 5 rotates, it will pull the two connecting plates 6 from different directions to one side, thus fixing the mineral product.

[0041] At this point, the robotic arm 10 can be activated, causing it to rotate the grinding disc 17 to grind the mineral product. When the grinding disc 17 needs to be replaced, the limiting ring 13 can be pulled upwards, causing it to move the limiting ring 14. After the limiting ring 14 moves, the multiple balls 12 will loosen, allowing the grinding disc 17 and connecting post 2 16 to be removed from the inside of the limiting shell 11. The grinding disc 17 and connecting post 2 16 are fixedly connected together, while one side of the limiting shell 11 is fixedly connected to the drive end of the robotic arm 10. Because the limiting ring 14 is always on the outside of the multiple balls 12 due to the spring 15 when the robotic arm 10 is restricted, it is used to restrict the movement of the grinding disc 17. Multiple balls 12 restrict this, and when the limiting ring 14 is driven by the limiting ring 13, the restriction on the multiple balls 12 is released. When restricted by the limiting ring 14, the inner side of the balls 12 will tightly clamp the connecting post 2 16, and the outer side of the connecting post 2 16 is provided with a groove to facilitate the restriction of the balls 12. When the balls 12 are loosened, the connecting post 2 16 can be easily removed, thereby realizing the quick replacement of the grinding disc 17. Before grinding mineral products, the blower 19 can be started, so that the powder from grinding is sucked into the interior of the base plate 1 through the hole at the top of the base plate 1 by the blower 19. The interior of the base plate 1 is provided with two filter barrels 18 to absorb the powder sucked down by the blower 19.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
