Abstract
Description
Technical Field
[0001] This invention belongs to the field of material pulverization technology, and specifically relates to a device for pulverizing and grinding cosmetic raw materials. Background Technology
[0002] Cosmetics refer to chemical industrial products or fine chemical products used by applying, spraying, or other similar methods to achieve the purpose of cleansing, maintaining, beautifying, modifying, and changing appearance, and maintaining a good condition. In the processing and production of cosmetics, many solid raw materials are used. These solid raw materials have a large particle size, which cannot meet the needs of cosmetic production. Therefore, these solid raw materials need to be ground. In the current cosmetic production process, depending on the different properties of different cosmetics, multiple raw materials usually need to be ground, pulverized, and mixed. The precision and efficiency of the grinding equipment directly affect the quality of cosmetics and is an indispensable core link in the modern beauty industry.
[0003] Cosmetic raw material crushing and grinding equipment is a key piece of equipment in cosmetic production to achieve fine processing of raw materials. Its core function is to precisely reduce the particle size of raw materials to the target fineness through multi-stage mechanical force to meet the requirements of different formulations for texture, color and stability. In the initial crushing stage, high-speed rotating rollers decompose large pieces of raw materials into particles through extrusion and shearing forces. Then, through the impact and friction of the grinding media inside the cylinder, the raw materials are deeply ground to refine the particles into the required mineral powder, thereby achieving the crushing and grinding of raw materials.
[0004] In the current cosmetic raw material processing process, the cosmetic industry has extremely strict standards for raw material particle size, requiring extremely small and uniform particle size to ensure that the product has a good texture and excellent absorption effect. However, after the cosmetic raw materials are crushed and ground, there are still some larger particles in the powder. The larger particles need to be screened to ensure the uniformity of powder particle size. After screening, the larger particles need to be collected by workers and then transported to the top of the crushing device for secondary crushing and grinding. The process is cumbersome and time-consuming, reducing the production efficiency of powder crushing and grinding.
[0005] Therefore, the present invention provides a cosmetic raw material pulverizing and grinding device. Summary of the Invention

[0017] The beneficial effects of this invention are as follows: 1. The cosmetic raw material pulverizing and grinding device of the present invention uses a sieving component to finely sieve the raw material powder after it has been refined by the grinding component, effectively separating the fine powder that meets the particle size requirements from the larger particles that do not meet the requirements. This avoids the larger particles from being mixed in the powder and affecting the overall quality of the cosmetics, ensuring that the raw materials entering the subsequent production stages are all fine powders with uniform particle size, thereby ensuring the delicate texture of the cosmetics and improving key performances such as the absorption effect of the product.
[0018] 2. The cosmetic raw material crushing and grinding device of the present invention collects larger particles screened out by the screening component through a recovery component and transports them back to the crushing chamber. These particles are then crushed and ground again with new raw materials entering the crushing chamber, forming a complete circular production process. This avoids waste of larger particles, improves the overall utilization rate of raw materials, and the circular operation mode ensures that the raw materials are fully crushed and ground. After multiple processing steps, the final powder meets the requirements, reducing production interruptions and repetitive operations caused by substandard raw materials, and improving overall production efficiency.
[0019] 3. The cosmetic raw material pulverizing and grinding device of the present invention, through the opening and closing component, initially blocks the opening of the recovery chamber with a blocking plate, preventing qualified powder that meets the particle size requirements after being screened by the fine sieve plate from accidentally entering the recovery chamber. This ensures that qualified powder can smoothly converge to the bottom of the arc-shaped material plate according to the predetermined process. When the fine sieve plate rotates downward, its bottom end applies a force to the blocking plate, causing the blocking plate to slide along the limiting slide groove and compress the torsion spring, thereby opening the opening of the recovery chamber. When the bottom end of the fine sieve plate aligns with the opening of the recovery chamber, larger particles can accurately enter the recovery chamber. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0024] like Figures 1 to 9 As shown, the present invention provides a technical solution: a cosmetic raw material crushing and grinding device, including a grinding chamber 1, a crushing chamber 2 fixedly connected above the grinding chamber 1, a feeding bin 3 fixedly connected above the crushing chamber 2, crushing rollers 4 symmetrically rotatably connected to the inner wall of the crushing chamber 2, transmission gears 5 fixedly connected to one end of the shaft of each crushing roller 4, the teeth of the two transmission gears 5 meshing with each other, a motor 6 fixedly installed outside the crushing chamber 2, the output shaft of the motor 6 fixedly connected to one end of the shaft of one of the crushing rollers 4, a sliding table 7 symmetrically fixedly installed inside the crushing chamber 2, a grinding component and a screening component arranged inside the grinding chamber 1, the screening component located below the grinding component, the grinding component is used to grind the raw material, the screening component is used to screen the ground raw material, and a recycling component is also arranged on the side of the screening component, the larger raw material particles after screening can be recycled back into the crushing chamber 2 through the recycling component.
[0025] During operation: The raw materials to be processed are continuously fed from the feeding hopper 3. The raw materials can enter the crushing chamber 2 through the feeding hopper 3. Under the guidance of the two sliding platforms 7, the raw materials can accurately enter between the two crushing rollers 4. Driven by the motor 6, one of the crushing rollers 4 rotates, and under the meshing relationship of the two transmission gears 5, the two crushing rollers 4 rotate simultaneously, and the rotation directions are exactly opposite. When the two crushing rollers 4 rotate in opposite directions, the raw materials falling above will be continuously squeezed, thereby completing the initial crushing. After crushing, the raw materials will first fall into the grinding component inside the feeding hopper 3. The grinding component can grind the initially crushed raw materials. Under the continuous action of the grinding component, the raw materials can be refined into powder. Because cosmetics have very strict requirements for the particle size of raw materials, the particles need to be extremely small and uniform after grinding to ensure the texture, absorption effect, and other properties of the product. After a single crushing and grinding, uneven grinding may occur, and larger particles will still be mixed in with the powder. These larger particles mixed in with the powder will affect the texture of the cosmetic. After grinding, the raw materials fall into the screening component, which can screen out the larger particles mixed in with the powder, thereby removing the larger particles from the powder. After screening, the larger particles can be recycled back into the crushing chamber 2 through the recycling component, and then crushed and ground again with the raw materials entering the crushing chamber 2. The larger particles are then screened and recycled again, and this cycle is repeated until the powder that meets the requirements is obtained. In this way, the large particles after screening are recycled and crushed through the recycling component, eliminating the need for a separate transfer and processing step, reducing energy waste, achieving energy saving, and improving production efficiency. Through the above embodiments, the screening component meticulously screens the raw material powder refined by the grinding component, effectively separating fine powder that meets the particle size requirements from larger particles that do not. This prevents these larger particles from mixing in the powder and affecting the overall quality of the cosmetics, ensuring that the raw materials entering subsequent production stages are all fine powders with uniform particle size. This guarantees the delicate texture of the cosmetics and improves key performance aspects such as product absorption. The recycling component collects the larger particles screened out by the screening component and transports them back into the grinding chamber 2. They are then crushed and ground again with the new raw materials entering the grinding chamber 2, forming a complete circular production process. This avoids the waste of larger particles and improves the overall utilization rate of raw materials. The circular operation mode allows the raw materials to be fully crushed and ground, and after multiple processing steps, the final powder that meets the requirements is obtained. This reduces production interruptions and repetitive operations caused by unqualified raw materials, and improves overall production efficiency.
[0026] like Figures 5 to 6 As shown, the grinding assembly includes a feed plate 8, which is located below the crushing roller 4. The feed plate 8 is fixedly installed inside the grinding chamber 1. A grinding arc plate 9 is fixedly connected inside the grinding chamber 1. Several mesh holes are evenly opened on the surface of the grinding arc plate 9. A grinding roller 10 is arranged above the grinding arc plate 9. A dual-drive assembly is arranged outside the grinding roller 10. The dual-drive assembly can drive the grinding roller 10 to revolve and rotate along the upper surface of the grinding arc plate 9.
[0027] During operation: After being crushed by the crushing roller 4, the raw material falls above the feed plate 8. Guided by the inclined surface of the feed plate 8, the raw material enters the upper surface of the grinding arc plate 9 from the tail opening of the feed plate 8. The grinding roller 10 revolves and rotates along the upper surface of the grinding arc plate 9. During the revolution, the grinding roller 10 makes a circular motion around a certain center point in the grinding chamber 1. This allows the grinding roller 10 to contact different areas of the upper surface of the grinding arc plate 9 in sequence, and to fully cover and grind the raw material that enters the upper surface of the grinding arc plate 9 from the tail opening of the feed plate 8. The rotation of the grinding roller 10 makes the grinding roller 10 rotate continuously, which enhances its crushing and friction on the raw material. With the cooperation of revolution and rotation, the raw material is subjected to continuous and multi-directional forces between the grinding roller 10 and the grinding arc plate 9. It is constantly squeezed, sheared and rubbed, thus rapidly refining it. Finally, the ground raw material will fall through the mesh to the screening component.
[0028] like Figures 5 to 6As shown, the dual-drive assembly includes a servo motor 11, which is fixedly installed on the outer wall of the grinding chamber 1. The output shaft of the servo motor 11 is fixedly connected to a main rotating shaft 12, which is rotatably connected to the inner wall of the feed plate 8. A swing rod 13 is symmetrically fixedly connected to the outer wall of the main rotating shaft 12, and a self-rotating shaft 14 is rotatably connected between the two swing rods 13. The grinding roller 10 is fixedly connected to the outer wall of the self-rotating shaft 14.
[0029] During operation: When the servo motor 11 starts, its output shaft drives the main rotating shaft 12 to rotate. During the rotation of the main rotating shaft 12, it drives the symmetrical swing rod 13 on its outer wall to make a circular motion. While the swing rod 13 revolves around the main rotating shaft 12, it drives the grinding roller 10 to revolve along the upper surface of the grinding arc plate 9, so that the grinding roller 10 can contact different areas of the upper surface of the grinding arc plate 9 in sequence to grind the raw materials that fall above the grinding arc plate 9.
[0030] like Figures 5 to 6 As shown, the dual-drive assembly also includes two gears 15, which are fixedly connected to both ends of the rotation shaft 14. The teeth of the gears 15 are meshed with arc-shaped rack plates 16, which are fixedly connected to the outer wall of the grinding chamber 1.
[0031] During operation: As the grinding roller 10 revolves along the upper surface of the grinding arc plate 9, the gear 15 rolls along the arc-shaped rack plate 16 as the rotation shaft 14 revolves. Under the meshing transmission action of the gear 15 and the arc-shaped rack plate 16, the rotation shaft 14 drives the grinding roller 10 to rotate, thereby realizing the motion process of the grinding roller 10 revolving and rotating along the upper surface of the grinding arc plate 9, which fully grinds the raw materials.
[0032] like Figures 5 to 6 As shown, a scraper 17 is fixedly connected between the bottoms of the swing rods 13. One end of the scraper 17 is set as a pointed tip and fits against the bottom of the grinding arc plate 9.
[0033] During operation: When the swing arm 13 revolves around the main rotating shaft 12, it drives the scraper 17 to revolve along the bottom of the grinding arc plate 9. During the revolution, the tip of the scraper is always in contact with the bottom of the grinding arc plate 9, continuously scraping off the powder adhering to the bottom surface of the grinding arc plate 9. This effectively avoids the powder from adhering and accumulating on the bottom of the grinding arc plate 9 for a long time, preventing the accumulation from affecting the normal feeding function of the mesh holes of the grinding arc plate 9, reducing the waste of raw materials, and scraping off the adhering powder in time so that it can enter the subsequent production process, thereby improving the utilization rate of raw materials.
[0034] like Figures 7 to 8As shown, the screening assembly includes two fine screen plates 20, which are symmetrically arranged inside the grinding chamber 1. A vibrator 23 is fixedly installed at the bottom of each fine screen plate 20. An arc-shaped material plate 21 is fixedly connected to the inner wall of the grinding chamber 1. One end of the fine screen plate 20 is in contact with the inner wall of the arc-shaped material plate 21. A second feeding plate 18 is symmetrically fixedly connected to the inner wall of the grinding chamber 1. The second feeding plate 18 is located above the fine screen plate 20. A discharge hopper 22 is fixedly connected to the bottom of the arc-shaped material plate 21.
[0035] During operation: After grinding, the raw material falls onto the upper surface of the fine sieve plate 20. Initially, the two fine sieve plates 20 are in a V-shape. At this time, the feed plate 18 guides the material, ensuring that the raw material falls accurately to the top of the fine sieve plate 20 after grinding. Then, it slides down the slope of the fine sieve plate 20. During the sliding process, under the action of the vibrator 23, the surface of the fine sieve plate 20 is always in a state of micro-vibration. The vibrator 23 usually contains an eccentric block and a motor. When the motor drives the eccentric block to rotate through the transmission component, the eccentric block generates centrifugal inertial force to impact the bottom of the fine sieve plate 20, causing the bottom of the fine sieve plate 20 to vibrate slightly. Under the action of slight vibration, the surface tension of the fine sieve plate 20 changes. This micro-vibration state can effectively prevent powder from clogging the sieve holes. This process ensures smooth sieving and allows the raw materials to bounce slightly on the fine sieve plate 20. This facilitates the rapid passage of uniformly sized powder through the sieve holes of the fine sieve plate 20, causing it to fall onto the surface of the arc-shaped material plate 21. After falling onto the arc-shaped material plate 21, the powder naturally gathers at the bottom of the arc-shaped material plate 21 due to its arc structure and flows smoothly out of the discharge hopper 22 for easy collection. Larger particles that cannot pass through the sieve holes of the fine sieve plate 20 flow down the slope of the fine sieve plate 20 and gather at the intersection of the fine sieve plate 20 and the arc-shaped material plate 21, remaining at the bottom of the slope of the fine sieve plate 20. This completes the sieving process of the raw materials after grinding, effectively separating powder that meets the particle size requirements from larger particles and ensuring the quality of the final cosmetic raw materials.
[0036] like Figures 7 to 8 As shown, both sides of the arc-shaped material plate 21 are fixedly connected to the recovery chamber 27. One end of the fine screen plate 20 is fixedly connected to the inner wall of the rotating shaft 19, which is rotatably connected to the inner wall of the grinding chamber 1. Support components are provided below the fine screen plate 20 to support the bottom of the fine screen plate 20. One side of the recovery chamber 27 is provided with an opening and closing component to seal and open the opening end of the recovery chamber 27.
[0037] During operation: In the initial state, the bottom end of the fine sieve plate 20 maintains a stable V-shape under the solid support of the support components. Under the continuous action of the vibrator 23, the fine sieve plate 20 will only rotate slightly upwards. The opening end of the recovery chamber 27 is closed under the effective sealing of the opening and closing components. At this time, the qualified powder that falls above the arc-shaped material plate 21 after being screened by the sieve holes of the fine sieve plate 20 will not accidentally enter the recovery chamber 27, but will smoothly gather at the bottom of the arc-shaped material plate 21 and flow out from the discharge chamber 22 for collection. When the amount of larger particles accumulated above the bottom end of the fine sieve plate 20 reaches a certain level... First, the support component removes the support for the bottom of the fine screen plate 20. Without support, the fine screen plate 20 will rotate downward around the pivot rod 19 under the combined action of its own weight and the pressure of the particles above. As the bottom end of the fine screen plate 20 rotates downward along the surface of the arc-shaped material plate 21, it will trigger the opening and closing component to put it in the open state. Finally, when the bottom end of the fine screen plate 20 rotates to form a docking relationship with the opening end of the recovery chamber 27, the accumulated larger particles will enter the interior of the recovery chamber 27 and then enter the recovery component, where they will participate in the crushing and grinding operation again along with the newly added raw materials.
[0038] like Figures 7 to 8 As shown, the support assembly includes a fixed plate 24, which is fixedly connected to the inner wall of the grinding chamber 1. Arc-shaped telescopic rods 25 are fixedly connected to both sides of the fixed plate 24. Support balls 26 are fixedly connected to the output ends of the arc-shaped telescopic rods 25. The outer wall of the support balls 26 is in contact with the bottom of the fine sieve plate 20.
[0039] During operation: In the initial stage, the support ball 26 is tightly attached to the bottom of the fine screen plate 20, providing stable support and maintaining the fine screen plate 20 in a stable V-shape. When a certain number of larger particles accumulate above the bottom of the fine screen plate 20, the arc-shaped telescopic rod 25 begins to retract, and its output end drives the support ball 26 to move closer to the fixed plate 24. As the support ball 26 moves, the support for the bottom of the fine screen plate 20 is gradually removed. At this time, under the combined action of its own weight and the pressure of the larger particles above, the fine screen plate 20 rotates downward around the pivot rod 19. The bottom end of the fine screen plate 20 rotates downward along the surface of the arc-shaped material plate 21 until it connects with the opening end of the recovery bin 27, allowing the larger particles to enter the recovery bin 27 for further processing. Afterward, when the larger particles are cleared, the arc-shaped telescopic rod 25 extends, pushing the support ball 26 back to the bottom of the fine screen plate 20, restoring the support for the fine screen plate 20 and returning it to its initial stable V-shape, ready for the next screening operation.
[0040] like Figures 7 to 8As shown, each of the opening and closing components includes a blocking plate 28. One side of the blocking plate 28 is slidably connected to the inner side of the arc-shaped plate 21. The inner side of the arc-shaped plate 21 is symmetrically and fixedly connected to a limiting groove 30. The outer wall of the blocking plate 28 is slidably connected to the inner wall of the limiting groove 30. A torsion spring 29 is fixedly connected between one side of the blocking plate 28 and the inner side of the limiting groove 30.
[0041] During operation: In the initial state, the blocking plate 28, under the elastic force of the torsion spring 29, tightly seals the opening of the recovery chamber 27, preventing powder from accidentally entering the recovery chamber 27. When the support assembly removes its support for the bottom of the fine sieve plate 20, as the fine sieve plate 20 rotates downwards around the pivot rod 19, its bottom end contacts the blocking plate 28 and applies a force towards the inside of the recovery chamber 27. Under this force, the blocking plate 28 slides along the inner wall of the limiting groove 30, compressing the torsion spring 29, thereby gradually opening the chamber. When the bottom end of the fine screen plate 20 rotates to form a docking relationship with the opening end of the recycling bin 27, the blocking plate 28 is fully opened, allowing larger particles to smoothly enter the recycling bin 27. After the larger particles are cleared, the fine screen plate 20 returns to its initial support state under the action of the support component. Under the rebound force of the torsion spring 29, the blocking plate 28 slides in the opposite direction along the limiting slide groove 30, re-sealing the opening end of the recycling bin 27 and returning to the initial sealing state, waiting for the next screening and recycling operation.
[0042] like Figure 2 and Figure 9 As shown, the recycling assembly includes two return cylinders 31, which are fixedly connected to both sides of the grinding chamber 1. The return cylinders 31 are rotatably connected to the inside of the return cylinders 31. A second motor 33 is fixedly installed at the top of each return cylinder 31. The output shaft of the second motor 33 is fixedly connected to the shaft of the second motor 32. One end of the recycling bin 27 is fixedly connected to the bottom end of the return cylinder 31. A return material bin body 34 is fixedly connected to the top of each return cylinder 31. The outlet end of the return material bin body 34 is in contact with the surface of the sliding table 7.
[0043] During operation: When larger particles enter the recycling bin 27, they fall to the bottom of the return conveyor 31, which is fixedly connected to it, due to their own gravity. At this time, the motor 33, which is fixedly installed at the top of the return conveyor 31, starts. Its output shaft drives the spiral conveyor blades 32 to rotate, which in turn causes the spiral conveyor blades 32 to rotate inside the return conveyor 31. Under the rotation of the spiral conveyor blades 32, the larger particles that fall to the bottom of the return conveyor 31 are gradually conveyed upward. As the spiral conveyor blades 32 continue to rotate, the larger particles are lifted to the top of the return conveyor 31 and then discharged through the return hopper 34, which is fixedly connected to the top of the return conveyor 31. Since the outlet end of the return hopper 34 is in contact with the surface of the sliding table 7, the discharged larger particles fall onto the sliding table 7 and, guided by the sliding table 7, participate again in the subsequent crushing and grinding process.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
