[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This anti-agglomeration mixing equipment for plastic additive powder utilizes a multi-motor collaborative drive composite motion mechanism in its mixing components. A second motor drives the stirring frame to achieve shearing and convection dispersion of the materials within the drum, completing the initial mixing. A first motor drives the rotating frame and mixing drum to rotate, enhancing material spatial migration and collision. A third motor, via a sprocket and transmission chain, causes the rotating frame to rotate in the opposite direction, forming a multi-dimensional, complementary motion trajectory. This multi-axis linkage effectively overcomes the limitations of traditional single-axis stirring, significantly improving dispersion efficiency and uniformity. By enhancing inter-particle friction and collision, it efficiently eliminates agglomeration, ensuring that the mixed quality of the plastic additive powder meets high-standard process requirements, providing high-quality raw materials with uniform performance for subsequent applications such as 3D printing.

[0015] 2. This plastic additive powder anti-agglomeration mixing equipment utilizes a lifting assembly. The scheme employs precise linear drive of an electric push rod, combined with the mechanical linkage of a connecting plate and a moving rack, to efficiently convert linear motion into rotary transmission via a gear set. Through the synergistic action of the rotating shaft, the first gear, and the second gear, combined with the guiding constraint of the sleeve on the lifting rack, stable and precise vertical displacement of the lifting plate is achieved. This transmission design, leveraging the high precision of the gear and rack mechanism, ensures the accuracy and stability of the mixing drum height adjustment. It can flexibly adapt to different feeding requirements under various working conditions, effectively improving the equipment's versatility and ease of operation, reducing manual intervention costs, and ensuring efficient operation of the feeding process.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4. This utility model provides a technical solution: a plastic additive powder anti-agglomeration mixing device, including a base plate 1, a lifting component 3 is provided on the base plate 1, and a mixing component 2 is provided on the lifting component 3;

[0023] The mixing assembly 2 includes a fixed frame 201, a rotating wheel 202, a rotating frame 203, a rotating frame 204, a first motor 205, a mixing tank 206, a second motor 207, a stirring frame 208, a transmission chain 209, a third motor 210, and a sprocket 211. The rotating wheel 202 is movably mounted on the fixed frame 201, the rotating frame 203 is movably mounted on the rotating wheel 202, and the rotating frame 204 is movably mounted on the rotating frame 203. The first motor 205 is mounted on the rotating frame 203, and its drive end is connected to the rotating frame 204. The mixing tank 206 is located on the rotating frame 204. The second motor 207 is mounted on the mixing tank 206. The stirring frame 208 is installed inside the mixing tank 206, and its drive end is connected to the second motor 207. The transmission chain 209 is located on the mixing tank 206. On the rotating frame 203, the third motor 210 is mounted on the fixed frame 201. The sprocket 211 is mounted on the drive end of the third motor 210 and is movably connected to the transmission chain 209. When performing the mixing and dispersion of plastic additive powder, the plastic additive powder is placed into the mixing tank 206. The second motor 207 is started, and its power output drives the stirring frame 208 to rotate at high speed in the mixing tank 206. Initial dispersion is achieved through shearing, convection and other actions. Then, the first motor 205 is driven, which drives the rotating frame 204 to perform circular motion around the axis of the rotating frame 203. The mixing tank 206 rotates synchronously with the rotating frame 204, further enhancing the spatial migration and collision of materials. At the same time, the third motor 210 is started to generate rotational power for the sprocket 211, which is transmitted to the rotating frame 203 through the transmission chain 209, causing the rotating frame 203 to rotate in the opposite direction to the rotating frame 204. This multi-axis linkage collaborative working mode utilizes the internal dispersion of the stirring rack 208, the rotation of the rotating rack 204 and the mixing tank 206, and the compound motion formed by the reverse rotation of the rotating rack 203 to significantly improve the dispersion efficiency and uniformity of plastic additive powder, effectively eliminate agglomeration, and ensure that the mixing quality of plastic additive powder meets high standards.

[0024] Furthermore, the fixing frame 201 is provided with reinforcing ribs, and the base plate 1 is provided with pads. The reinforcing ribs increase the stability of the fixing frame 201, and the pads make the base plate 1 more stable when placed.

[0025] Furthermore, the first motor 205 is fixed to the rotating frame 203 by bolts, and the stirring frame 208 is provided with several stirring blades. The first motor 205, which is fixed by bolts, is easy to install and remove on the rotating frame 203, and the several stirring blades are convenient to disperse the plastic additive powder and prevent agglomeration.

[0026] Furthermore, the lifting assembly 3 includes a sleeve 301, a lifting rack 302, a lifting plate 303, a support frame 304, a rotating shaft 305, a first gear 306, a second gear 307, a placement frame 308, a moving rack 309, an electric push rod 310, and a connecting plate 311. The sleeve 301 is mounted on the base plate 1, the lifting rack 302 is movably disposed within the sleeve 301, the lifting plate 303 is mounted on the lifting rack 302, the support frame 304 is mounted on the base plate 1, the rotating shaft 305 is movably disposed on the support frame 304, and the first gear 306 is mounted on the rotating shaft 305 and the first gear 307... The first gear 306 meshes with the lifting rack 302. The second gear 307 is mounted on the rotating shaft 305. The placement frame 308 is mounted on the base plate 1. The movable rack 309 is movably mounted on the placement frame 308 and meshes with the second gear 307. The electric push rod 310 is mounted on the placement frame 308. The connecting plate 311 is mounted on the drive end of the electric push rod 310 and connected to the movable rack 309. When the height of the mixing tank 206 needs to be adjusted to meet the feeding requirements, the electric push rod 310 is activated, using its precise linear drive capability to drive the connecting plate 311 to move. Through mechanical linkage, the connecting plate 311 causes the movable rack 309 to slide smoothly along the preset track of the placement frame 308, thereby converting linear motion into rotational motion, driving the second gear 307 to rotate. The rotational power of the second gear 307 is transmitted to the first gear 306 via the rotating shaft 305, forming a highly efficient transmission of the gear set. During this process, the rotation of the first gear 306 drives the lifting rack 302 to move vertically under the guidance and constraint of the sleeve 301. Thanks to the precise transmission characteristics of the gear and rack mechanism, the lifting plate 303 is smoothly raised and lowered. Ultimately, this allows for flexible adjustment of the height of the mixing drum 206, effectively meeting the feeding requirements under different working conditions and ensuring convenient and efficient material conveying.

[0027] Furthermore, the lifting rack 302 is adapted to the sleeve 301, and the base plate 1 is provided with a telescopic rod 312. The adapted lifting rack 302 moves more stably within the sleeve 301. Several telescopic rods 312 are provided, and several telescopic rods 312 are circumferentially arranged on the base plate 1. The fixed end of the telescopic rod 312 is installed on the base plate 1, and the movable end of the telescopic rod 312 is connected to the lifting plate 303. The movable end of the telescopic rod 312 moves with the lifting plate 303, making the movement of the lifting plate 303 more stable.

[0028] Furthermore, the support frame 304 is provided with reinforcing ribs, and the movable rack 309 is adapted to the placement frame 308. The reinforcing ribs increase the stability of the support frame 304, and the adapted movable rack 309 moves stably on the placement frame 308.

[0029] Furthermore, the second motor 207 is fixed to the mixing tank 206 by bolts, and the rotating shaft 305 is adapted to the support frame 304. The second motor 207, which is fixed by bolts, is easy to install and remove on the mixing tank 206, and the adapted rotating shaft 305 is more stable when rotating on the support frame 304.

[0030] Working Principle: When the height of the mixing drum 206 needs to be adjusted to meet the feeding requirements, the electric push rod 310 is activated, using its precise linear drive capability to move the connecting plate 311. Through mechanical linkage, the connecting plate 311 causes the moving rack 309 to slide smoothly along the preset track of the placement frame 308, thus converting linear motion into rotational motion, driving the second gear 307 to rotate. The rotational power of the second gear 307 is transmitted to the first gear 306 via the rotating shaft 305, forming a highly efficient transmission of the gear set. During this process, the rotation of the first gear 306 drives the lifting rack 302 to move vertically under the guidance and constraint of the sleeve 301. Thanks to the precise transmission characteristics of the gear and rack mechanism, the lifting plate 303 is raised and lowered smoothly. Ultimately, the height of the mixing drum 206 can be flexibly adjusted to effectively meet the feeding requirements under different working conditions, ensuring the convenience and efficiency of material conveying. When carrying out the mixing and dispersion of plastic additive powder, the plastic additive powder is placed into the mixing drum 206, and the second motor 207 is started. With its power output, the stirring frame 208 is driven to rotate at high speed in the mixing drum 206, and the initial dispersion is achieved through shearing, convection and other actions. Then, the first motor 205 is driven to drive the rotating frame 204 to move in a circle around the axis of the rotating frame 203. The mixing drum 206 rotates synchronously with the rotating frame 204, further enhancing the spatial migration and collision of materials. At the same time, the third motor 210 is started to generate rotational power for the sprocket 211, which is transmitted to the rotating frame 203 through the transmission chain 209, causing the rotating frame 203 to rotate in the opposite direction to the rotating frame 204. This multi-axis linkage collaborative working mode utilizes the internal dispersion of the stirring rack 208, the rotation of the rotating rack 204 and the mixing tank 206, and the compound motion formed by the reverse rotation of the rotating rack 203 to significantly improve the dispersion efficiency and uniformity of plastic additive powder, effectively eliminate agglomeration, and ensure that the mixing quality of plastic additive powder meets high standards.
