Abstract
Description
Technical Field
[0001] This utility model relates to the field of powder processing equipment technology, specifically to a homogenizer for powder processing. Background Technology
[0002] Powder processing equipment is widely used in industries such as chemical, pharmaceutical, and food processing for grinding, mixing, or homogenizing powders to meet production requirements for particle uniformity and quality stability. With increasing industrial demand for efficient processing, homogenizers need to possess features such as high-efficiency grinding and flexible operation to adapt to various powder materials and production scenarios.
[0003] Current powder processing relies on equipment such as high-speed mixers, ball mills, and vibrating screens to achieve powder homogenization through shearing, collision, or vibration. For example, high-speed mixers use rotating blades to break down agglomerates, while ball mills refine particles through grinding balls. Patents such as CN2290604Y describe powder homogenizers that optimize mixing parameter control, while JP6403029B2 improves uniformity through mixing and homogenization. Although these technologies are widely used, additional equipment is required when processing lumpy powders.
[0004] In small factories, existing homogenizers are insufficient for effectively handling lumpy powders, often requiring separate grinding equipment (such as hammer crushers) for pretreatment. This leads to cumbersome processes, large equipment footprint, and increased operational complexity and maintenance burden. The hardness and agglomeration characteristics of lumpy powders result in uneven mixing, affecting product quality. For example, uneven distribution of pharmaceutical components can lead to unstable efficacy, or differences in the taste of food can impact consumer experience. Furthermore, existing equipment has poor adaptability to different materials, making it difficult to meet the diverse, small-batch production needs of small factories, thus limiting flexibility and efficiency.

[0020] like Figures 1 to 7 As shown, the homogenizer for powder processing includes a homogenizing chamber 1 and a grinding mechanism 2. The homogenizing chamber 1 is used to contain powder and provide processing space. A feed inlet 11 is provided at the top of the homogenizing chamber 1, serving as the channel for powder to enter the homogenizing chamber 1. A grinding plate 111 is fixedly installed inside the feed inlet 11, and the grinding plate 111 is fixed to the inner wall of the feed inlet 11 to ensure its stability during the grinding process. The grinding mechanism 2 is located directly above the grinding plate 111 and performs grinding processing on the powder on the grinding plate 111.
[0021] In actual use, the powder falls onto the surface of the grinding plate 111 through the feed inlet 11. Then, the rolling mechanism 2 is activated to perform reciprocating rolling motion along the surface of the grinding plate 111. During the rolling process, the rolling mechanism 2 comes into direct contact with the powder on the grinding plate 111, further refining the powder particles and making their particle size distribution more uniform.
[0022] In this embodiment, the compaction mechanism 2 includes two supports 21, two swing arms 22, a second motor 23, a reciprocating assembly 24, a compaction assembly 25, and a switching assembly 26. The two supports 21 are symmetrically installed on both sides of the top of the feed inlet 11. The supports 21 provide a stable mounting base for the second motor 23. The two swing arms 22 are disposed between the two supports 21. The second motor 23 is connected to the supports 21, and its output shaft passes through the supports 21 and is connected to the reciprocating assembly 24, used to drive the movement of the compaction mechanism 2. The reciprocating assembly 24 is mounted on the swing arms 22 and cooperates with the swing arms 22. The compaction assembly 25 is disposed between the swing arms 22 and is connected to the swing arms 22 through a rotating shaft or a fixed shaft, used to compact the powder. The working surface of the compaction assembly 25 rolls in contact with the grinding plate 111, which can effectively crush the powder and improve the homogenization effect. The switching assembly 26 is connected to the swing arms 22 to realize the switching of the working mode of the compaction assembly 25.
[0023] In actual use, the powder falls onto the surface of the grinding plate 111 through the feed port 11. The second motor 23 is started, and its output shaft drives the swing arm 22 to move through the reciprocating assembly 24, which in turn drives the reciprocating assembly 24 to drive the crushing assembly 25 to perform crushing motion. During the crushing process, the crushing assembly 25 switches to different forms through the switching assembly 26.
[0024] In this embodiment, the reciprocating assembly 24 includes a connecting plate 241, a slider 242, and a slide groove 243. One end of the connecting plate 241 is connected to the output shaft of the second motor 23, and the other end is connected to the slider 242. The slider 242 is fixed to the other end of the connecting plate 241. The slide groove 243 is formed on the swing arm 22, creating a linear sliding track. The slider 242 and the slide groove 243 are slidably connected.
[0025] In actual use, powder enters the homogenizing chamber 1 through the feed inlet 11 and is evenly distributed on the surface of the grinding plate 111. The second motor 23 is started, and its output shaft drives the connecting plate 241 to swing. The movement of the connecting plate 241 further drives the slider 242 to reciprocate along the groove 243 on the swing arm 22. The guiding function of the groove 243 ensures the stable movement of the slider 242, preventing deviation or shaking during the crushing process.
[0026] In this embodiment, the crushing assembly 25 includes a mounting plate 251, a rotating shaft 252, a scraper 253, and a crushing roller 254. The mounting plate 251 is the main component of the crushing assembly 25 and is located between two swing arms 22. It is rotatably connected to the two swing arms 22 via the rotating shaft 252, ensuring that the mounting plate 251 can rotate between the swing arms 22 to achieve function switching. The rotating shaft 252 passes through the center of the mounting plate 251 and is connected to the mounting plate 251. It is also rotatably connected to the corresponding holes of the two swing arms 22 via bearings. The scraper 253 is fixed to one end of the mounting plate 251. Its working edge is designed with a slight arc to efficiently remove powder residue from the surface of the grinding plate 111 and to achieve feeding. The crushing roller 254 is fixed to the other end of the mounting plate 251. The surface of the crushing roller 254 is smooth to achieve uniform crushing of powder when it rolls in contact with the grinding plate 111.
[0027] In actual use, the crushing assembly 25 moves under the drive of the swing arm 22 via the rotation of the rotating shaft 252. The mounting plate 251, supported by the rotating shaft 252, rotates around the shaft 252 between the two swing arms 22. Driven by the mounting plate 251, the crushing roller 254 rolls in contact with the surface of the grinding plate 111. At this time, the baffles 1112 on the openings 1111 on both sides of the grinding plate 111 are pushed into the feed inlet 11, blocking the openings and preventing powder from falling out of the openings 1111 under the pressure and push of the crushing roller 254. When grinding is complete, the mounting plate 251 is rotated by the switching assembly 26 to make the working edge of the scraper 253 contact the surface of the grinding plate 111. Simultaneously, the baffles 1112 can be manually removed from the feed inlet 11 to allow material to flow. Driven by the swing arm 22, the scraper 253 slides along the surface of the grinding plate 111, removing residual powder through physical scraping action. This not only prevents powder accumulation, but also allows the powder on the grinding plate 111 to be discharged through the openings 1111 on both sides by the reciprocating motion of the swing arm 22. When the scraper 253 reciprocates, it conveys the powder towards both ends of the grinding plate 111.
[0028] In this embodiment, the switching assembly 26 includes an electric push rod 261, a turntable 262, and a connecting rod 263. The electric push rod 261 is the power source of the switching assembly 26, fixed to a swing arm 22, and rotatably connected to the swing arm 22. The installation position of the electric push rod 261 ensures that its drive end can freely extend and retract without interfering with the normal movement of the swing arm 22. The drive end of the electric push rod 261 is connected to the connecting rod 263. The turntable 262 is fixedly connected to the rotating shaft 252. The turntable 262 is connected to the connecting rod 263. One end of the connecting rod 263 is rotatably connected to the drive end of the electric push rod 261, and the other end is rotatably connected to the edge connection point of the turntable 262. The length and strength design of the connecting rod 263 can withstand the pushing and pulling force of the electric push rod 261, ensuring the stable rotational movement of the turntable 262.
[0029] In practical use, the drive end of the electric push rod 261 extends or retracts, pushing or pulling the turntable 262 to rotate via the connecting rod 263. The turntable 262 is fixed on the rotating shaft 252, and its rotation drives the rotating shaft 252 to rotate, thereby driving the mounting plate 251 to rotate around the rotating shaft 252. The rotation of the mounting plate 251 causes the scraper 253 or the grinding roller 254 to come into contact with the grinding plate 111.
[0030] In this embodiment, a first motor 13, a drive assembly 14, and a stirring rod 12 are mounted on the homogenizing chamber 1. The first motor 13 is fixedly mounted on the surface of the homogenizing chamber 1 and is fixedly connected to one end of the drive assembly 14 to ensure the stability and reliability of power transmission. The drive assembly 14 is a power transmission component, including a gear set and a belt drive structure. One end is fixedly connected to the output shaft of the first motor 13, and the other end is connected to the stirring rod 12. The stirring rod 12 is installed inside the homogenizing chamber 1 and is rotatably connected to the inner wall of the homogenizing chamber 1 for stirring powdered materials.
[0031] In actual use, when the powder crushed by the crushing component 25 falls into the homogenizing chamber 1 through the scraper 253, the first motor 13 drives the stirring rod 12 to move through the drive component 14 to stir the crushed powder. When the stirring is completed, the baffle of the discharge port 15 is opened by the staff to discharge the powder.
[0032] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
