[0004] When in use, the mixing device controls the feeding pipe to add material into the mixing box through the first feeding valve. The feeding pipe is fixed on the side of the mixing box, causing the added material to accumulate in one place, which requires re-mixing later, increasing the mixing time.

[0005] To address the aforementioned problems, this invention proposes a mixing device for tungsten powder preparation. Utility Model Content

[0006] To address the problems existing in the background technology, this utility model proposes a mixing device for tungsten powder preparation.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: it includes a preparation tank, a material box is fixedly inserted through the top surface of the preparation tank, a throwing plate is rotatably connected to the discharge port at the bottom of the material box, a notch is opened at one end of the throwing plate connected to the material box, and a baffle is rotatably provided at the opening at the other end of the throwing plate.

[0008] A fixed rod is fixedly connected to one side of the throwing plate. A driving assembly is installed inside the preparation tank. The driving assembly drives the fixed rod to swing back and forth. A stirring assembly is installed inside the preparation tank.

[0009] Furthermore, a feed pipe is fixedly connected to the top of the preparation tank, the bottom of the preparation tank is funnel-shaped, and a discharge pipe is fixedly connected to the bottommost end of the preparation tank, with a valve installed on the discharge pipe.

[0010] Furthermore, an arc-shaped positioning plate is fixedly connected to the discharge port at the bottom of the material box. One end of the material throwing plate connected to the material box is cylindrical. The cylindrical part at the end of the material throwing plate is rotatably connected to the inside of the positioning plate, and a notch is opened on the cylindrical part at the end of the material throwing plate.

[0011] Furthermore, connecting plates are fixedly connected to both sides of the end of the throwing plate away from the notch, and one end of the baffle is rotatably disposed between the two connecting plates;

[0012] Both sides of one end of the baffle are fixedly connected to rotating shafts, which are rotatably connected to corresponding connecting plates. Each rotating shaft is fitted with a torsion spring, one end of which is fixedly connected to the baffle, and the other end of which is fixedly connected to the corresponding connecting plate.

[0013] Furthermore, the drive assembly includes a second motor, which is fixedly mounted on the outer side of the preparation tank. The output end of the second motor is fixedly connected to a shaft, which is horizontally arranged and rotatably passes through the side of the preparation tank. One end of the shaft is fixedly connected to a straight rod, and the side of the straight rod away from the shaft is rotatably connected to a connecting rod. The end of the connecting rod is fixedly connected to a slider.

[0014] The fixed rod has a groove, and the slider is slidably connected inside the groove.

[0015] Furthermore, the stirring assembly includes a stirring rod, which is rotatably connected to the inside of the preparation tank, and a plurality of stirring bars are uniformly fixedly connected to the outer surface of the stirring rod;

[0016] The top of the preparation tank is fixedly connected to a first motor, and the top of the stirring rod rotates through the top surface of the preparation tank and is then fixedly connected to the output end of the first motor.

[0017] Furthermore, several crossbars are fixedly connected to the outer surface of the bottom of the stirring rod. The crossbars are arranged in a circumferential array about the stirring rod.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The mixing device for tungsten powder preparation is equipped with a throwing plate. The end of the throwing plate is connected to the material box through a notch, so that the material in the material box will enter the throwing plate through the notch. Then, the second motor drives the shaft to rotate, causing the straight rod and the connecting rod to rotate. This pushes the slider to slide inside the chute. At the same time, the connecting rod will rotate on one side of the straight rod, thereby pushing the fixed rod and the throwing plate to swing back and forth. This causes the throwing plate to sprinkle the material to different places in the preparation tank, increasing the sprinkling range, so as to better mix and improve the mixing efficiency.

[0020] 2. The mixing device for tungsten powder preparation is equipped with a baffle. When the driving throwing plate rotates towards the middle of the preparation tank, the baffle will move away from the opening at the end of the throwing plate due to inertia, so that the material in the throwing plate can be discharged from the opening. When the throwing plate rotates towards the inner wall of the preparation tank, the baffle will block the opening at the end of the throwing plate to prevent the material from being scattered in one place and to make the material spread evenly.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1-5 As shown, the technical solution adopted by this utility model is as follows: a mixing device for tungsten powder preparation, including a preparation tank 1, with a feed pipe 3 fixedly connected to the top of the preparation tank 1. The feed pipe 3 facilitates the introduction of tungsten powder to be mixed into the preparation tank 1.

[0029] The bottom of the preparation tank 1 is funnel-shaped, and a discharge pipe 6 is fixedly connected to the bottom of the preparation tank 1. A valve is installed on the discharge pipe 6. By opening the valve, the mixed material in the preparation tank 1 can be discharged through the discharge pipe 6.

[0030] A material box 4 is fixedly inserted through the top surface of the preparation tank 1, and the material box 4 contains additive materials for mixing. A discharge port at the bottom of the material box 4 is rotatably connected to a throwing plate 9, and a notch 10 is opened at the end of the throwing plate 9 connected to the material box 4. This allows the throwing plate 9 to communicate with the inner cavity of the material box 4 through the notch 10, so that the material in the material box 4 can enter the interior of the throwing plate 9 through the notch 10.

[0031] An arc-shaped positioning plate 20 is fixedly connected to the discharge port at the bottom of the material box 4. One end of the throwing plate 9 connected to the material box 4 is cylindrical, and the cylindrical part of the throwing plate 9 is rotatably connected to the inside of the positioning plate 20. A notch 10 is formed on the cylindrical part of the throwing plate 9. The positioning plate 20 positions the end of the throwing plate 9 on the material box 4. When the notch 10 rotates to the positioning plate 20, the positioning plate 20 will seal the notch 10.

[0032] A baffle 17 is rotatably installed at the opening at the other end of the throwing plate 9. The opening of the throwing plate 9 is inclined, and the baffle 17 is located on the side of the opening of the throwing plate 9 away from the middle of the preparation tank 1.

[0033] Both sides of the throwing plate 9, which is away from the notch 10, are fixedly connected to connecting plates 16, and one end of the baffle 17 is rotatably set between the two connecting plates 16.

[0034] Both sides of one end of the baffle 17 are fixedly connected to rotating shafts, which are rotatably connected to corresponding connecting plates 16. The baffle 17 and the connecting plate 16 are connected by the rotating shafts. A torsion spring is fitted on each of the two rotating shafts, with one end of the torsion spring fixedly connected to the baffle 17 and the other end fixedly connected to the corresponding connecting plate 16. In the initial state, the torsion spring drives the baffle 17 to rotate to the opening of the throwing plate 9, thereby blocking the opening of the throwing plate 9.

[0035] A fixing rod 14 is fixedly connected to one side of the throwing plate 9. A driving assembly is installed inside the preparation tank 1, which drives the fixing rod 14 to swing back and forth.

[0036] The drive assembly includes a second motor 5, which is fixedly mounted on the outer side of the preparation tank 1. A shaft 11 is fixedly connected to the output end of the second motor 5. The shaft 11 is horizontally arranged and rotates through the side of the preparation tank 1.

[0037] A support rod 7 is fixedly connected to the top surface of the preparation tank 1, and the shaft 11 rotates through the support rod 7. The support rod 7 increases the stability of the shaft 11.

[0038] A straight rod 13 is fixedly connected to one end of the shaft 11, and a connecting rod 15 is rotatably connected to the side of the straight rod 13 away from the shaft 11. A slider 18 is fixedly connected to the end of the connecting rod 15. When the shaft 11 rotates, it will drive the straight rod 13, the connecting rod 15, and the slider 18 to rotate.

[0039] A groove 12 is provided on the fixed rod 14, and a slider 18 is slidably connected inside the groove 12. The shaft 11 drives the fixed rod 14 to rotate through the slider 18, thereby causing the throwing plate 9 to rotate.

[0040] The preparation tank 1 is equipped with a stirring assembly.

[0041] The stirring assembly includes a stirring rod 8, which is rotatably connected to the inside of the preparation tank 1. Several stirring bars are uniformly fixed to the outer surface of the stirring rod 8. This allows the stirring rod 8 to mix the materials within the preparation tank 1 via the stirring bars.

[0042] A first motor 2 is fixedly connected to the top of the preparation tank 1. The top end of the stirring rod 8 rotates through the top surface of the preparation tank 1 and is then fixedly connected to the output end of the first motor 2. The first motor 2 drives the stirring rod 8 to rotate.

[0043] Several crossbars are fixedly connected to the outer surface of the bottom of the stirring rod 8, and these crossbars are arranged in a circumferential array about the stirring rod 8. A scraper 19 is fixedly connected to the end of each crossbar, and the scraper 19 is slidably connected to the inner wall of the bottom of the preparation tank 1. When the stirring rod 8 drives the crossbars and scraper 19 to rotate, the scraper 19 scrapes away the material on the inner wall of the preparation tank 1, thereby discharging more material and reducing waste. At the same time, the crossbars also have a stirring effect.

[0044] Working principle:

[0045] In use, tungsten powder is fed into the preparation tank 1 through the feed pipe 3, and the additives required for tungsten powder preparation are added into the material box 4.

[0046] The material in the hopper 4 will enter the interior of the throwing plate 9 through the notch 10, and the baffle 17 will block the opening at the end of the throwing plate 9.

[0047] Start the first motor 2 and the second motor 5.

[0048] The second motor 5 drives the shaft 11 to rotate, and the shaft 11 rotates on the support rod 7. The shaft 11 drives the straight rod 13 to rotate, causing the connecting rod 15 and the slider 18 to rotate around the axis of rotation of the shaft 11.

[0049] The slider 18 slides back and forth inside the groove 12, while the connecting rod 15 rotates on one side of the straight rod 13. This causes the slider 18 to push the fixed rod 14 to swing back and forth, which in turn drives the throwing plate 9 to swing back and forth.

[0050] When the throwing plate 9 rotates towards the side closer to the middle of the preparation tank 1, the baffle 17 will rotate under the action of inertia, overcoming the torsion force of the torsion spring, causing the baffle 17 to rotate away from the throwing plate 9, and causing the torsion spring to twist.

[0051] The notch 10 at the end of the throwing plate 9 will rotate to one side of the positioning plate 20, and the positioning plate 20 will seal the notch 10, thereby sealing the discharge port of the material box 4. At this time, the material in the throwing plate 9 will be discharged from the baffle 17 into the preparation tank 1, and the material will be scattered.

[0052] When the throwing plate 9 rotates towards the inner wall of the preparation tank 1, the baffle 17 will rotate to the opening of the throwing plate 9 under the action of inertia and torsion spring, so that the baffle 17 blocks the opening of the throwing plate 9.

[0053] The notch 10 of the throwing plate 9 will rotate away from the positioning plate 20, so that the material in the material box 4 can enter the throwing plate 9, preventing the material from spilling onto the inner wall of the preparation tank 1. Then the throwing plate 9 continues to rotate to spread the material.

[0054] The first motor 2 drives the stirring rod 8 to rotate, causing the stirring bar on the stirring rod 8 to rotate and mix the materials in the preparation tank 1.

[0055] After mixing is complete, open the valve on the discharge pipe 6 to discharge the material. The first motor 2 enables the scraper 19 to rotate on the inner wall of the preparation tank 1, scraping off the material on the inner wall of the preparation tank 1.

[0056] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
