[0012] Beneficial effects of the metal powder injection molding raw material mixing device for rapid batching of the present invention:

[0013] 1. The dual stirring design of the stirring seat 1 and the stirring seat 2 in the mixing mechanism, wherein the paddle 1 on the stirring seat 1 and the paddle 2 on the stirring seat 2 face opposite directions, forms a counter-rotating stirring force. This design causes the raw materials to be subjected to shear and impact forces from different directions in the mixing barrel, effectively solving the problems of uneven mixing and agglomeration caused by differences in the physical properties of the raw materials (such as particle size, shape, density). At the same time, both the paddle 1 and the paddle 2 fit the inner wall of the mixing barrel, ensuring full contact of the raw materials during the mixing process, further improving the mixing efficiency.

[0014] 2. The batching components in the batching mechanism rotate through the meshing of the toothed ring and the toothed disc, thereby controlling the opening and closing of the discharge hole and the proportion of the discharge. This design makes the batching process more flexible and accurate, and the proportion of different raw materials can be quickly adjusted according to actual needs. At the same time, the sensor installed inside the batching barrel can monitor the amount of raw materials in real time, and replenish them in time through the feeding pipe, ensuring the continuity and stability of the batching.

[0015] 3. During the mixing process, the nozzle below the collecting plate will blow out high-pressure airflow to break up and mix the mixed raw materials again. This design not only improves the mixing effect, but also ensures the uniform distribution of the raw materials in the mixing barrel. At the same time, the use of high-pressure airflow also reduces the adhesion of raw materials during the mixing process and reduces the maintenance cost of the equipment.

After mixing, it falls to the collecting plate 16, in which the paddle 131 and the paddle 2 141 face opposite directions, forming a counter-rotating stirring force. This design causes the raw materials to be subjected to shear force and impact force from different directions in the mixing barrel 11, and the nozzle 17 blows high-pressure airflow to break them up again during the fall, ensuring thorough mixing.

[0038] The batching assembly 24 includes a batching barrel 241 rotatably mounted inside the mounting port 211, a barrel cover 242 is provided on the top of the batching barrel 241, a plurality of discharge holes 243 are opened at the bottom of the batching barrel 241, and a baffle 244 is rotatably connected to the bottom of the batching barrel 241, a fixing rod 2441 is provided on the top of the baffle 244, the fixing rod 2441 penetrates the batching barrel 241, the barrel cover 242 is fixedly connected to the support frame 25, a mounting ring 245 is fixedly connected to the circumferential outer wall of the batching barrel 241, a limiting ring 2451 is fixedly connected to the circumferential outer wall of the batching barrel 241 at a position above the mounting ring 245, a gear ring 246 is clamped on the outer wall of the limiting ring 2451, the bottom end of the gear ring 246 extends to the inside of the mounting ring 245, and is slidably connected to the inner wall of the mounting ring 245, a plurality of telescopic rods 247 are evenly arranged inside the mounting ring 245, and the output end of the telescopic rod 247 is fixedly connected to the bottom end of the gear ring 246.

[0039] When the gear ring 246 is in normal state, it is located at the lowest point of the limit ring 2451. When the telescopic rod 247 pushes it up, its height will be flush with the gear disc 232, and the gear ring 246 will mesh with the gear disc 232. A feed port is provided on the top of the barrel cover 242, and the feed port is used to connect the feed pipe. The feed pipe can be used to feed into the inside of the batching barrel 241 at any time, so that the batching barrel 241 can be kept fully stocked at any time. The bottom of the batching barrel 241 is a circle, and the circle is divided into two halves, and the discharge holes 243 are evenly opened in one half of the area. The position of the baffle 244 is fixed, and it is connected to the support frame 25 through the fixing rod 2441. In addition to being used to fix the baffle 244, it is also used to assist in maintaining the stability of the batching barrel 241 during rotation. The number of discharge holes 243 can be opened according to actual needs.

[0040] When batching, the toothed disc 232 is first driven to rotate by driving the second motor 231. When materials in different batching components 24 need to be added, the telescopic rod 247 in the batching component 24 that needs to be added will push the toothed ring 246 to rise, so that the toothed ring 246 and the toothed disc 232 are engaged and driven to rotate. The rotation of the toothed ring 246 will drive the batching barrel 241 to rotate, and the rotation of the batching barrel 241 will drive the discharge hole 243 to break away from the obstruction of the baffle 244. When the baffle 244 is no longer obstructed, the material will leak out through the discharge hole 243. The proportion of the discharged material is controlled by controlling the amount of leakage from the discharge hole 243. A sensor is provided inside the batching barrel 241. When the batching barrel 241 discharges materials, the feeding pipe will be controlled to feed materials. The materials discharged through the discharge hole 243 will fall into the collecting disk 22, and the materials will be sent to the mixing mechanism 1 through the collecting disk 22.

[0041] When the mixing mechanism 1 is started, the gear 123 is driven to rotate by the driving motor 121, and the gear 123 drives the stirring seat 14 to rotate counterclockwise through the connecting shaft 142. At the same time, the gear 123 drives the stirring seat 13 to rotate clockwise through the gear 2 124. The paddle 131 and the paddle 2 141 are both in contact with the inner wall of the mixing barrel 11. When the material enters the mixing mechanism 1, it will first fall onto the stirring seat 14. The stirring seat 14 drives the paddle 2 141 to rotate rapidly, which will quickly beat the fallen material and pre-disperse it. When the material is on the stirring seat 14, as the paddle 2 141 moves rapidly, it will also Due to the downward movement of gravity, when the material leaves the range of blade 2 141, it will continue to move at high speed due to inertia, and the rotation direction of blade 1 131 is opposite to that of blade 2 141, so the material will collide with blade 1 131. The collision of the two forces can completely break up the material and prevent the existence of agglomerates. The material can be fully mixed by the breaking and stirring of blade 1 131 and blade 2 141. After mixing, it will fall onto collecting plate 1 16, and then fall into the bottom of mixing barrel 11 through collecting plate 16. In the process of falling, nozzle 17 will blow out high-pressure airflow, and the material will be broken up and mixed again by the high-pressure airflow to ensure that the mixing is more thorough.

[0042] The mixing mechanism 1 adopts a double stirring design, the stirring seat 13 and the stirring seat 2 14 rotate in opposite directions, and the paddle 1 131 and the paddle 2 141 face opposite directions, forming a multi-directional stirring force, which effectively solves the problem of uneven mixing and agglomeration of raw materials and improves the mixing efficiency. The batching mechanism 2 controls the discharge of materials through the meshing of the toothed ring 246 and the toothed disk 232, flexibly and accurately adjusts the ratio, and the sensor ensures continuous and stable batching. During mixing, the nozzle 17 blows out a high-pressure airflow to disperse the mixed raw materials again, improve the effect, reduce adhesion, and reduce maintenance costs.

[0043] The stirring seat 1 13 and the stirring seat 2 14 in the mixing mechanism 1 realize synchronous but opposite rotation through the meshing of the gear 1 123 and the gear 2 124. This structural connection not only simplifies the transmission mechanism and reduces energy consumption, but also improves the stability and durability of the equipment. In addition, the fixed connection between the fixing ring 15 and the inner wall of the mixing barrel 11, and the rotational connection between the stirring seat 13 and the stirring seat 2 14 and the fixed platform 12, all ensure the stability and reliability during the mixing process.

[0044] The components of the present invention are tightly connected and clearly structured, making the maintenance and care of the equipment simpler and more convenient.
