Description

Technical Field

[0001] The present invention relates to the technical field of metal powder processing, and particularly to a device for mixing metal powder injection molding raw materials with rapid batching. Background Art

[0002] The metal powder injection molding process, as an important part of modern advanced manufacturing technology, poses extremely high requirements for the rapid batching and efficient mixing of raw materials. However, there are a series of problems and deficiencies in these two key links in the prior art, which seriously restrict the improvement of production efficiency and the stability of product quality.

[0003] One of the main problems of existing mechanisms is the poor mixing effect in raw material mixing. Due to the differences in physical properties such as particle size, shape, and density of raw materials, as well as design defects of mixing equipment, the raw materials after mixing are often unevenly distributed and agglomerated. This not only affects the uniformity and consistency of products, but also may cause defects such as pores and cracks during the injection molding process, thereby reducing the quality and performance of products. In addition, problems such as low mixing efficiency, insufficient adaptability and flexibility, and difficulties in maintenance and repair also seriously restrict the application and development of existing mixing mechanisms in the metal powder injection molding process.

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

[0013] 1. Through the dual agitation design of agitator base one and agitator base two in the mixing mechanism, where the blades one on agitator base one and the blades two on agitator base two face opposite directions, a reverse rotational agitation force is formed. This design enables the raw materials in the mixing barrel to be subjected to shear forces and impact forces from different directions, 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 blades one and blades two are in contact with the inner wall of the mixing barrel, ensuring full contact of the raw materials during the mixing process and further improving the mixing efficiency.

[0014] 2. The dosing component in the dosing mechanism rotates through the meshing of the toothed ring and the toothed disc, thereby controlling the opening and closing of the discharge holes and the proportion of the discharged material. This design makes the dosing process more flexible and precise, and can quickly adjust the ratio of different raw materials according to actual needs. At the same time, the sensors installed inside the dosing barrel can monitor the quantity of raw materials in real time and replenish them in a timely manner through the feeding pipe, ensuring the continuity and stability of dosing.

[0015] 3. During the mixing process, the nozzle below the aggregate tray one blows out high-pressure air flow to re-disperse and mix the mixed raw materials. 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 air flow also reduces the adhesion phenomenon of the raw materials during the mixing process and lowers the maintenance cost of the equipment.

[0030] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , Figure 6 , Figure 7 , a device for mixing raw materials for metal powder injection molding with rapid batching, comprising a mixing mechanism 1. The mixing mechanism 1 includes a mixing barrel 11. A fixed platform 12 is fixedly connected at a position near the top inside the mixing barrel 11. A stirring seat 13 is rotatably connected to the top of the fixed platform 12. A plurality of first blades 131 are evenly arranged on the outer wall of the stirring seat 13. A stirring seat 14 is rotatably connected to the top of the stirring seat 13. A plurality of second blades 141 are evenly arranged on the outer wall of the stirring seat 14. A docking groove 132 is opened at the center of the bottom of the stirring seat 13. An installation disk 122 is arranged at the position corresponding to the docking groove 132 on the top of the fixed platform 12. Docking teeth 133 are arranged on the circumferential inner wall of the docking groove 132. A first gear 123 is rotatably connected at the center between the installation disk 122 and the fixed platform 12. A second gear 124 is meshed and connected to one side of the first gear 123. The second gear 124 is meshed and connected to the docking teeth 133. A first driving motor 121 is arranged at the center inside the fixed platform 12. The output end of the first driving motor 121 penetrates through the fixed platform 12 and is fixedly connected to the first gear 123. A connecting shaft 142 is fixedly connected to the center of the bottom of the stirring seat 14. The bottom end of the connecting shaft 142 penetrates through the stirring seat 13 and the installation disk 122, and the bottom end of the connecting shaft 142 is fixedly connected to the first gear 123. An aggregate tray 16 is arranged at a position below the fixed platform 12 inside the mixing barrel 11. A spray head 17 is connected to the outer wall of the aggregate tray 16. The spray head 17 is used to connect an external air pump to blow out high-pressure air flow during the mixing process to further disperse and mix the raw materials in the mixing barrel 11. The orientations of the first blades 131 are opposite to those of the second blades 141. Both the first blades 131 and the second blades 141 are in contact with the inner wall of the mixing barrel 11.

[0031] By adopting the above technical solution, the mixing mechanism 1 is activated. The first driving motor 121 drives the first gear 123 to rotate, driving the second stirring seat 14 to rotate counterclockwise, and at the same time driving the first stirring seat 13 to rotate clockwise through the second gear 124. The first blade 131 and the second blade 141 stir against the wall. The raw materials fall on the second stirring seat 14 and are quickly dispersed, and move downward due to gravity. After leaving the second blade 141, they continue to move due to inertia and collide with the first blade 131 rotating in the opposite direction, being completely dispersed to prevent agglomeration. After mixing, they fall into the first aggregate tray 16. Among them, the first blade 131 and the second blade 141 face in opposite directions, forming a stirring force of reverse rotation. This design enables the raw materials to be subjected to shear forces and impact forces from different directions inside the mixing barrel 11, and the nozzle 17 blows high-pressure air flow during the falling process to disperse them again, ensuring thorough mixing.

[0032] It further includes a batching mechanism 2. The batching mechanism 2 includes a mounting frame 26 fixedly installed on the outer wall of the mixing barrel 11. The top of the mounting frame 26 is fixedly connected with a fixed disk 21. A second aggregate tray 22 is arranged at the bottom of the fixed disk 21. The bottom end of the second aggregate tray 22 is fixedly connected with the top of the mixing barrel 11. A number of mounting openings 211 are evenly formed at the top of the fixed disk 21. A batching component 24 is rotatably connected inside the mounting opening 211. A first fixing frame 23 is arranged at the center position of the top of the fixed disk 21, and this first fixing frame 23 is located among the batching components 24. A toothed disk 232 is rotatably connected inside the top end of the first fixing frame 23. A second driving motor 231 is arranged inside the first fixing frame 23. The output end of the second driving motor 231 is fixedly connected with the toothed disk 232. A support frame 25 is fixedly connected to the top of the fixed disk 21 near the batching component 24.

[0033] By adopting the above technical solution, the second driving motor 231 drives the toothed disk 232 to rotate. The batching component 24 makes contact with the toothed disk 232 through lifting, and controls the discharge switch of the batching component 24 through indirect contact, and at the same time controls the discharge proportion of the batching component 24.

[0034] The batching component 24 includes a batching barrel 241 rotatably installed inside the mounting opening 211. A barrel cover 242 is arranged at the top of the batching barrel 241. A number of discharge holes 243 are formed at the bottom of the batching barrel 241. At the same time, a baffle 244 is rotatably connected to the bottom of the batching barrel 241. An installation 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 above the installation ring 245. A toothed ring 246 is clamped on the outer wall of the limiting ring 2451. The bottom end of the toothed ring 246 extends into the installation ring 245 and is slidably connected to the inner wall of the installation ring 245. A number of telescopic rods 247 are arranged inside the installation ring 245. The output end of the telescopic rod 247 is fixedly connected to the bottom end of the toothed ring 246. A fixing rod 2441 is arranged at the top of the baffle 244. The fixing rod 2441 penetrates through the batching barrel 241, the barrel cover 242 and is fixedly connected to the external support frame 25.

[0035] By adopting the above technical solution, the telescopic rod 247 is used to push the toothed ring 246 upward, so that the toothed ring 246 is butted and engaged with the toothed disk 232 and driven to rotate. The rotation of the toothed ring 246 drives the batching barrel 241 to rotate, and the rotation of the batching barrel 241 drives the discharge hole 243 to move out of the shielding of the baffle 244. When there is no shielding of the baffle 244, the material will leak out through the discharge hole 243, and the proportion of the discharged material is controlled by controlling the quantity of the material leaking out through the discharge hole 243.

[0036] When the present invention is in use, the mixing mechanism 1 includes a mixing barrel 11. A fixed platform 12 is fixedly connected inside the mixing barrel 11 near the top position.

The gear two 124 is meshed and connected to the docking teeth 133. A driving motor one 121 is arranged at the center position inside the fixed platform 12. The output end of the driving motor one 121 penetrates through the fixed platform 12 and is fixedly connected to the gear one 123. A connecting shaft 142 is fixedly connected to the center position of the bottom of the stirring seat two 14. The bottom end of the connecting shaft 142 penetrates through the stirring seat one 13 and the installation disk 122, and the bottom end of the connecting shaft 142 is fixedly connected to the gear one 123. The orientations of the paddle blades one 131 are opposite to those of the paddle blades two 141. An aggregate disk one 16 is arranged inside the mixing barrel 11 at the position below the fixed platform 12. A spray head 17 is connected to the outer wall of the aggregate disk one 16. The spray head 17 is used to connect an external air pump.

[0037] The batching mechanism 2 includes a mounting frame 26 fixedly installed on the outer wall of the mixing barrel 11. A fixed disk 21 is fixedly connected to the top of the mounting frame 26. An aggregate disk two 22 is arranged at the bottom of the fixed disk 21. The bottom end of the aggregate disk two 22 is fixedly connected to the top of the mixing barrel 11. A plurality of mounting openings 211 are evenly formed at the top of the fixed disk 21. A batching assembly 24 is rotatably connected inside the mounting openings 211. A fixed frame one 23 is fixedly connected to the center position between the batching assemblies 24 at the top of the fixed disk 21. A toothed disk 232 is rotatably connected inside the top end of the fixed frame one 23. A driving motor two 231 is arranged inside the fixed frame one 23. The output end of the driving motor two 231 penetrates through the fixed frame one 23 and is fixedly connected to the toothed disk 232. A support frame 25 is fixedly connected to the top of the fixed disk 21. The support frame 25 is arranged on the outer circle of the batching assembly 24.

[0038] The batching component 24 includes a batching barrel 241 rotatably installed inside the installation port 211. A barrel cover 242 is provided at the top of the batching barrel 241. A number of discharge holes 243 are opened at the bottom of the batching barrel 241. At the same time, a baffle 244 is rotatably connected to the bottom of the batching barrel 241. A fixing rod 2441 is provided at the top of the baffle 244. The fixing rod 2441 penetrates through the batching barrel 241, the barrel cover 242 and is fixedly connected to the support frame 25. An installation 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 installation ring 245. A toothed ring 246 is clamped on the outer wall of the limiting ring 2451. The bottom end of the toothed ring 246 extends into the installation ring 245 and is slidably connected to the inner wall of the installation ring 245. A number of telescopic rods 247 are evenly arranged inside the installation ring 245. The output end of the telescopic rod 247 is fixedly connected to the bottom end of the toothed ring 246.

[0039] When the toothed ring 246 is in the normal state, it is located at the lowest position of the limiting ring 2451. When the telescopic rod 247 pushes it to rise, its height will be flush with the toothed disc 232. At the same time, the toothed ring 246 will mesh with the toothed disc 232. An inlet is opened at the top of the barrel cover 242. The inlet is used to connect the feeding pipe. Through the feeding pipe, the batching barrel 241 can be fed at any time, so that the batching barrel 241 can be kept fully supplied with materials at any time during batching. The bottom of the batching barrel 241 is a circle. The circle is divided into two halves, and the discharge holes 243 are evenly opened in one of the halves. The position of the baffle 244 is fixed. It is connected to the support frame 25 through the fixing rod 2441. In addition to fixing 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] During batching, first, the driving motor two 231 drives the toothed disc 232 to rotate. When adding materials from different batching components 24, the telescopic rod 247 in the batching component 24 to be added will push the toothed ring 246 to rise, so that the toothed ring 246 is butted and meshed with the toothed disc 232 and is driven to rotate. The rotation of the toothed ring 246 will drive the batching barrel 241 to rotate. The rotation of the batching barrel 241 will drive the discharge holes 243 to break away from the occlusion of the baffle 244. When there is no occlusion of the baffle 244, the materials will leak out through the discharge holes 243. The proportion of the discharged materials is controlled by controlling the number of materials leaking out through the discharge holes 243. An inductor is provided inside the batching barrel 241. When the batching barrel 241 discharges materials, the feeding pipe will be controlled to supply materials. The materials discharged through the discharge holes 243 will fall into the aggregate tray two 22, and the materials will be sent into the mixing mechanism 1 through the aggregate tray two 22.

[0041] When the mixing mechanism 1 is started, it will drive the first gear 123 to rotate through the first driving motor 121. The first gear 123 drives the second mixing seat 14 to rotate counterclockwise through the connecting shaft 142. At the same time, the first gear 123 drives the first mixing seat 13 to rotate clockwise through the second gear 124. The first paddle 131 and the second paddle 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 second mixing seat 14. The second mixing seat 14 drives the second paddle 141 to rotate rapidly, which will quickly pat the falling material and pre-disperse it at the same time. When the material is on the second mixing seat 14, while moving rapidly with the second paddle 141, it will also move downward due to gravity. When the material leaves the range of the second paddle 141, due to inertia, it will continue to move at high speed. And the rotation direction of the first paddle 131 is opposite to that of the second paddle 141, so the material will collide with the first paddle 131. The collision of the two forces can completely disperse the material and prevent the existence of agglomerates. Through the dispersion and stirring of the first paddle 131 and the second paddle 141, the material can be fully mixed. When the mixing is completed, it will fall onto the first collecting tray 16, and then fall into the bottom of the mixing barrel 11 through the first collecting tray 16. During its falling process, the nozzle 17 will blow out high-pressure air flow, and the material will be dispersed and mixed again by the high-pressure air flow to ensure more thorough mixing.

[0042] The mixing mechanism 1 adopts a double-stirring design. The first mixing seat 13 and the second mixing seat 14 rotate reversely, and the first paddle 131 and the second paddle 141 face in opposite directions, forming a multi-directional stirring force, effectively solving the problems of uneven mixing and agglomeration of raw materials and improving the mixing efficiency. The batching mechanism 2 controls the discharge through the engagement of the toothed ring 246 and the toothed disc 232, flexibly and precisely adjusts the ratio, and the inductor ensures continuous and stable batching. During mixing, the nozzle 17 blows out high-pressure air flow, which disperses and mixes the raw materials again, improves the effect, reduces adhesion, and reduces the maintenance cost.

[0043] The first mixing seat 13 and the second mixing seat 14 in the mixing mechanism 1 achieve synchronous but reverse rotation through the engagement of the first gear 123 and the second gear 124. This structural connection not only simplifies the transmission mechanism, reduces energy consumption, but also improves the stability and durability of the equipment. In addition, the fixed connection between the fixed ring 15 and the inner wall of the mixing barrel 11, and the rotational connection between the first mixing seat 13 and the second mixing seat 14 and the fixed table 12 ensure the stability and reliability during the mixing process.

[0044] The components of the present invention are tightly connected and the structure is clear, making the maintenance and repair of the equipment simpler and more convenient. For example, the detachable connection between the batching barrel 241 and the barrel cover 242, and the rotational connection between the first mixing seat 13 and the second mixing seat 14 and the fixed table 12 are all convenient for cleaning and repairing the equipment.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
