[0002] Amid the rapid growth and increasing demands for precision in the electronics manufacturing industry, powder, as a fundamental raw material, faces a crucial impact on the performance of the final product, particularly due to its quality and mixing uniformity. Powders are typically composed of fine particles with varying physical and chemical properties. Interactions between powder particles, such as van der Waals forces and electrostatic forces, can cause the particles to agglomerate during storage and use, forming large aggregates. This agglomeration not only affects the powder's fluidity but, more importantly, its uniformity during mixing. Therefore, to ensure the quality and performance of electronic products, effective powder mixing is essential to break down agglomerates and achieve uniform particle distribution.

[0003] The utility model with Chinese patent publication number CN220589842U discloses a semi-vacuum variable speed powder stirring device including a stirring barrel and a cleaning structure. The top surface of the stirring barrel is covered with a barrel cover, and a motor is provided on the surface of the barrel cover. The bottom surface of the motor is fixedly connected to a connecting stirring rod. The cleaning structure includes an insertion groove and a connecting plate. An insertion groove is provided at the opening of the connecting stirring rod. A compression spring is fixedly connected to the surface of the insertion groove, and a circular slide is fixedly connected to the side of the compression spring away from the insertion groove. This solves the problem that when the existing powder mixer is stirring powder, a large amount of powder will stick to the inner wall of the stirring barrel due to the high-speed operation of the internal stirring device, thereby causing a large amount of powder mucus to accumulate on the inner wall of the stirring barrel and affecting the normal operation of the mixer.

[0004] In this patent, the compression springs are all arranged on the surface of the insertion groove. During operation, the compression springs will be exposed inside the mixing barrel and rotate with the stirring rod. During this process, the compression springs will contact and collide with the powder, which may easily cause damage to the compression springs and affect the normal operation of the stirring device.

[0028] In order to make the purpose, technical solutions and advantages of the embodiment of the present invention clearer, the following will be combined with the appended drawings of the embodiment of the present invention. Figure 1-5 , clearly and completely describing the technical solutions of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field fall within the scope of protection of the present invention.

[0029] like Figure 1-5 As shown: This embodiment provides a powder stirring device, including a rotating column 100 and an adjusting component 200, the middle of the rotating column 100 is fixedly connected to a plurality of connecting plates 101 arranged in a ring array, the middle of the connecting plates 101 are each provided with an adjusting component 200, the adjusting component 200 includes a connecting cylinder 201, a spring 202, a pressing plate 203 and a positioning column 204, the side of the connecting plate 101 away from the rotating column 100 is fixedly connected to a plurality of connecting cylinders 201 arranged in an upper and lower array, the interior of the connecting cylinder 201 is clamped with a spring 202, the inner wall of the connecting cylinder 201 is provided with a limiting groove, and the spring 202 is located at the adjacent connecting cylinder 2 01, the outer diameter of the spring 202 is equal to the diameter of the limiting groove, the middle of the connecting tube 201 is slidably connected with a positioning column 204, the diameter of the positioning column 204 is smaller than the diameter of the positioning column 204, the middle of the positioning column 204 is fixedly connected with a pressure plate 203, one side of the pressure plate 203 is in contact with the end of the adjacent spring 202 away from the connecting plate 101, the diameter of the pressure plate 203 is greater than the diameter of the spring 202, the diameter of the pressure plate 203 is greater than the inner diameter of the connecting tube 201, the diameter of the pressure plate 203 is equal to the inner diameter of the limiting groove, and one end of the positioning column 204 on the same side is provided with a scraping assembly 300;

[0030] When in use, the transmission end of the rotating column 100 is connected to the motor, and the rotating column 100 is driven to rotate by the motor. When the rotating column 100 rotates, the connecting plate 101 and the adjusting assembly 200 are driven to rotate synchronously. At the same time, the spring 202 is in a compressed state in the limiting groove and continuously applies pressure to the pressing plate 203. The pressing plate 203 begins to move under the pressure, and at the same time drives the positioning column 204 to move along the axis of the connecting cylinder 201, thereby causing the scraping assembly 300 to move accordingly, so that the scraping assembly 300 can fit the inner wall of the mixing container. The scraping assembly 300 cleans the inner wall of the mixing container while rotating with the adjusting assembly 200;

[0031] During this process, the spring 202 is always located in the inner wall of the connecting tube 201 in the limiting groove, effectively avoiding excessive contact between the powder and the spring 202, protecting the spring 202 from the influence of the powder, and extending the service life of the spring 202. At the same time, the positioning column 204 is always located in the middle of the spring 202 when the spring 202 contracts and cooperates with the limiting groove to position the position of the spring 202, ensuring the stability of the spring 202 during compression and rebound. The guidance of the positioning column 204 effectively reduces unnecessary shaking of the spring 202 and the scraping assembly 300 during movement, and effectively reduces the wear of the spring 202 caused by shaking. When the pressure of the spring 202 is applied, the pressure plate 203 transmits the elastic force to the positioning column 204. When the pressure plate 203 moves excessively, it will fit with the inner wall of one end of the limiting groove and be limited. By limiting the pressure plate 203, the position of the adjusting assembly 200 as a whole and the scraping assembly 300 is effectively limited, thereby improving the stability of the device operation. During the process of the scraping assembly 300 being fitted to the inner wall of the mixing container, the pressure on the pressure plate 203 by the spring 202 allows the scraping assembly 300 to maintain close contact with the inner wall, effectively cleaning the attachments on the inner wall and ensuring the efficiency of the mixing process.

[0032] The scraping assembly 300 is as follows Figure 1 As shown,

[0033] The scraping assembly 300 includes a fixed plate 301 and a curved plate 302. The pressure columns on the same side are all fixedly connected to the same fixed plate 301 at one end. The side of the fixed plate 301 away from the rotating column 100 is connected to the curved plate 302 via bolts 303. The outer curved surface of the curved plate 302 faces the side away from the rotating column 100.

[0034] When the scraping assembly 300 moves with the adjustment assembly 200, the outer curved surface of the curved plate 302 fits tightly against the inner wall of the mixing container. Due to the curved surface design of the curved plate 302, it can better adapt to the inner wall of the mixing container. When the rotating column 100 drives the connecting plate 101 and the adjustment assembly 200 to rotate, the scraping assembly 300, under the pressure of the spring 202, fits against the inner wall of the mixing container and performs a scraping action along the inner wall of the mixing container, effectively cleaning the attachments on the inner wall and ensuring the efficiency of the mixing process. At the same time, the bolt 303 allows the curved plate 302 to be replaced according to the diameter of the inner wall of the container to adapt to mixing containers of different diameters. When the scraping assembly 300 needs to be replaced or adjusted, it only needs to loosen the bolt 303 to quickly replace or adjust the position of the curved plate 302, making it convenient for maintenance and replacement. At the same time, the guiding effect of the positioning column 204 effectively reduces unnecessary shaking of the spring 202 and the scraping assembly 300 during movement, improving the stability of the device operation.

[0035] The guide mechanism 400 is as follows Figure 1 、 2As shown,

[0036] The guide mechanism 400 is further comprised of a guide post 401 and a guide plate 402. A plurality of guide posts 401 arranged in an upper and lower array are fixedly connected to one side of the fixed plate 301 close to the rotating post 100. A plurality of guide plates 402 arranged in an axial array along the connecting cylinder 201 are fixedly connected to the middle portion of the connecting cylinder 201 on the same side. The middle portions of the guide posts 401 are slidably connected to the middle portions of adjacent guide plates 402. A limit block 403 is fixedly connected to one end of the guide post 401 close to the rotating post 100. The diameter of the limit block 403 is larger than the diameter of the guide post 401.

[0037] When the scraper assembly 300 moves under the control of the adjustment assembly 200, the guide post 401 slides within the guide plate 402. The stop block 403 restricts excessive movement of the guide post 401, ensuring its stable position within the connecting cylinder 201. This allows the guide post 401 to effectively guide the scraper assembly 300 during operation, reducing the shaking of the spring 202 and the scraper assembly 300 during movement, further enhancing the stability and reliability of the entire powder mixing device. The sliding connection between the guide post 401 and the guide plate 402 allows the scraper assembly 300 to more flexibly adapt to changes in the shape and size of the inner wall of the mixing container, thereby achieving a more uniform and thorough mixing effect.

[0038] The fixing assembly 500 is as follows Figure 1 、 2 As shown,

[0039] A fixing assembly 500 is provided on one side of the connecting plate 101. The fixing assembly 500 includes a fixing post 501 and a clamping plate 502. The fixing post 501 is fixedly connected to the middle portion of one side of the connecting plate 101. The middle portion of the fixing post 501 is slidably connected to the middle portion of the adjacent guide plate 402. The end of the fixing post 501 away from the rotating post 100 is fixedly connected to the clamping plate 502. The clamping plate 502 is in contact with the side of the adjacent guide plate 402 away from the rotating post 100.

[0040] When this device is operating, the adjustment component 200, the scraping component 300 and the guide component all rotate with the rotating column 100, and the fixed component 500 is directly driven by the rotating column 100 and the connecting plate 101. As the transmission column and the connecting plate 101 rotate, the guide plate 402 is also driven to move. The clamping plate 502 fits tightly with the guide plate 402 to avoid shaking during movement. The transmission of the fixed component 500 effectively improves the stability and reliability of this device during operation.

[0041] Working principle:

[0042] The motor drives the rotating column 100 to rotate, driving the connecting plate 101 and the adjusting assembly 200 to rotate synchronously. The spring 202 is compressed in the limiting groove, applying pressure to the pressure plate 203. The pressure plate 203 moves, driving the positioning column 204 to move along the axis of the connecting cylinder 201, thereby moving the scraping assembly 300 to fit the inner wall of the mixing container. The scraping assembly 300 includes a fixed plate 301 and an arc plate 302. The outer arc surface of the arc plate 302 fits tightly with the inner wall of the mixing container. Under the pressure of the spring 202, the scraping assembly 300 scrapes along the inner wall to clean the container. To prevent attachments and ensure stirring efficiency, the guide mechanism 400 includes a guide post 401 and a guide plate 402. The guide post 401 is slidably connected to the guide plate 402. The limit block 403 limits excessive movement of the guide post 401, ensuring its stable position within the connecting cylinder 201, reducing the shaking of the spring 202 and the scraping assembly 300, and enhancing the stability and reliability of the device. The fixed assembly 500 includes a fixed post 501 and a clamping plate 502. The fixed post 501 is slidably connected to the guide plate 402, and the clamping plate 502 is in contact with the guide plate 402. The fixed assembly 500 is directly driven by the rotating column 100 and the connecting plate 101, driving the guide plate 402 to move. The transmission of the fixed assembly 500 improves the stability and reliability of the device during operation.
