[0002] Powder metallurgy is a process technology that produces metal powder or a mixture of metal powder and non-metallic powder as raw materials, and then forms and sinters them to manufacture metal materials, composite materials and various types of products. During processing, workers often use a mixing device to mix two or more powders. Although the existing mixing device can reduce the labor intensity of the workers, in actual use, the workers usually directly add different raw materials into the tank at one time, resulting in the different raw materials being piled up together, which requires a long time of stirring to evenly distribute the materials. This not only increases energy consumption, but also reduces work efficiency, so it needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] like Figures 1 to 5 As shown, the utility model provides a mixing device for powder metallurgy processing, comprising:

[0030] A support 1, a stirring tank 2 is arranged on the top of the support 1;

[0031] A driving mechanism, which is arranged above the stirring tank 2;

[0032] A main stirring mechanism, which is arranged inside the stirring tank 2;

[0033] Among them, the driving mechanism includes a brake motor 3, which is fixedly installed on the top of the mixing tank 2. The other end of the output shaft of the brake motor 3 is fixedly sleeved with a rotating shaft 4. The front of the rotating shaft 4 is fixedly connected with a disc 5. The bottom of the front of the disc 5 is hinged with a connecting rod 6. The other end of the connecting rod 6 is hinged with a lifting rod 7. Vertical plates 8 are fixedly installed on both sides of the bottom of the lifting rod 7. The bottom of the vertical plate 8 extends to the inside of the mixing tank 2. Both sides of the top of the inner wall of the mixing tank 2 are hinged with a material removal plate 9. A push-pull rod 10 is hinged between the material removal plate 9 and the vertical plate 8. The up and down movement of the vertical plate 8 can enable the push-pull rod 10 to drive the material removal plate 9 to swing left and right.

[0034] By starting the brake motor 3, the connecting rod 6 can drive the lifting rod 7 and the vertical plate 8 to reciprocate up and down, so that the push-pull rod 10 can drive the material-pickup plate 9 to rotate reciprocatingly, thereby breaking the added powder material into different positions in the mixing tank 2.

[0035] Among them, there are:

[0036] The main stirring mechanism is composed of a driving motor 11, a circular shaft 12 and stirring blades 13;

[0037] The driving motor 11 is fixedly installed in the middle of the top of the stirring tank 2, the circular shaft 12 is fixedly sleeved on the other end of the output shaft of the driving motor 11, the bottom end of the circular shaft 12 extends to the inside of the stirring tank 2, and the stirring blade 13 is fixedly installed on the outer surface of the circular shaft 12. The circular shaft 12 drives the stirring blade 13 to rotate to stir the metal powder.

[0038] By starting the driving motor 11, the circular shaft 12 can drive the stirring blade 13 to rotate, so that the mixed metal powder can be stirred to improve the mixing degree.

[0039] Among them, also include:

[0040] The auxiliary stirring mechanism is composed of a stirring rod 14, a driven gear 15 and a driving gear 16;

[0041] There are two stirring rods 14, which are rotatably connected to the two sides of the top of the inner wall of the stirring tank 2 respectively. The driven gear 15 is fixedly sleeved on the top of the outer surface of the stirring rod 14, and the driving gear 16 is fixedly sleeved on the top of the outer surface of the circular shaft 12. The driving gear 16 and the driven gear 15 are meshed and connected.

[0042] Through the design of the driven gear 15 and the driving gear 16, when the circular shaft 12 drives the driving gear 16 to rotate, the driven gear 15 can drive the stirring rod 14 to rotate in the opposite direction, thereby improving the stirring effect and making the metal powder mixed more evenly.

[0043] Among them, feed ports 17 are fixedly installed on both sides of the top of the stirring tank 2, and a screw cover 18 is threadedly sleeved on the top of the outer surface of the feed port 17.

[0044] By screwing the screw cap 18 onto the outer surface of the feed port 17, it is possible to prevent the metal powder from scattering and overflowing when being stirred, thereby affecting the processing environment.

[0045] The bottom of the inner wall of the stirring tank 2 is inclined, and a valve 19 is fixedly installed at the bottom of the stirring tank 2 .

[0046] By opening the valve 19 to release the seal of the mixing tank 2, the metal powder will slide out of the valve 19 along the inner wall of the mixing tank 2, and the staff can collect the mixed metal powder.

[0047] The scrapers 20 are fixedly connected to both sides of the bottom of the outer surface of the circular shaft 12 , and the other end of the scraper 20 is slidably connected to the inner wall of the mixing tank 2 .

[0048] The scraper 20 is designed to scrape off the metal powder adhering to the bottom of the inner wall of the mixing tank 2 to prevent accumulation and blockage.

[0049] The vertical plate 8 has a square appearance and a smooth outer surface.

[0050] The smooth outer surface design of the vertical plate 8 can make the vertical plate 8 move more smoothly when moving up and down.

[0051] The working principle and use process of this utility model:

[0052] When adding powder materials, the staff can first unscrew the screw cover 18, and then add materials into the mixing tank 2 from the feed port 17, and start the brake motor 3 at the same time. Due to the operation of the brake motor 3, the rotating shaft 4 will drive the disc 5 to rotate, so that the connecting rod 6 can drive the lifting rod 7 and the vertical plate 8 to reciprocate up and down, and then the push-pull rod 10 can drive the material plate 9 to reciprocate, so that the added metal powder materials can be scattered to different positions in the mixing tank 2, so that the powder materials are distributed more evenly, avoiding accumulation when adding materials, and realizing the initial mixing of materials when adding, so as to facilitate subsequent stirring and mixing, and improve work efficiency.

[0053] During stirring, the staff can screw on the screw cap 18 and then start the drive motor 11. Due to the operation of the drive motor 11, the circular shaft 12, the scraper 20 and the stirring blade 13 will be driven to rotate together. When the stirring blade 13 stirs the powder material, the driving gear 16 will rotate at the same time. Since the driving gear 16 is meshed and connected with the driven gear 15, the driven gear 15 can drive the stirring rod 14 to rotate together, and then the stirring rod 14 and the circular shaft 12 rotate in the opposite direction, and stir the powder material at the same time as the stirring blade 13, thereby improving the powder mixing effect and thus improving the mixing quality. At the same time, the scraper 20 scrapes off the metal powder adhered to the inner wall of the stirring tank 2, and finally the valve 19 can be opened to collect the mixed metal powder.
