[0002] In the process of powder metallurgy, it is usually necessary to use a variety of different materials to improve the strength and other properties of the alloy. In the prior art, traditional mixing is mostly carried out by stirring, flipping the mixing barrel, etc., and the mixing effects are different. However, after the mixing is completed, the powder will remain at the bottom of the equipment under the action of its own weight. In order to facilitate the discharge, the discharge port of the equipment is usually funnel-shaped, and the inclined discharge surface is easy to cause material accumulation, which makes it difficult to discharge the material completely. Manual material selection and knocking are required, which increases labor intensity and reduces work efficiency. Therefore, a mixer for powder metallurgy is proposed. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0015] The utility model will be further described below in conjunction with the accompanying drawings.

[0016] Please refer to Figure 1-2The utility model is a mixer for powder metallurgy, comprising a mixing barrel 1, the top of the mixing barrel 1 is rotatably connected to a rotating cover 2, the bottom of the rotating cover 2 is rotatably connected to a spiral feeding rod 4, the bottom of the spiral feeding rod 4 extends to the bottom of the mixing barrel 1, and a No. 1 material guide pipe 5 is fixedly connected to both sides of the rotating cover 2. Feeding bins 9 are provided on both sides of the bottom of the mixing barrel 1, and the No. 1 material guide pipe 5 is connected to the feeding bin 9.

[0017] A servo motor 3 is fixedly connected to the top of the rotating cover 2, and the output end of the servo motor 3 passes through the rotating cover 2 and is fixedly connected to the spiral feeding rod 4. The servo motor 3 drives the spiral feeding rod 4 to rotate, so that the powder in the feeding bin 9 enters the bottom of the mixing barrel 1 through the No. 2 guide pipe 10 and can be transported upward. The bottom of the No. 1 guide pipe 5 is fixedly connected to a connecting ring 6, and the bottom of the connecting ring 6 is fixedly connected to a bellows 7. The bottom of the bellows 7 is fixedly connected to a sealing ring 8, which is plugged into the feeding bin 9, and the top of the sealing ring 8 is fixedly connected to A guide rod 12 is connected, the top of the guide rod 12 is plugged into the connecting ring 6, and a number of springs 13 are fixedly connected between the connecting ring 6 and the sealing ring 8. By lifting the sealing ring 8 upward, the sealing ring 8 can be moved out of the feeding bin 9, and then the rotating cover 2 is rotated to open the top of the feeding bin 9 to achieve the purpose of feeding. A No. 2 material guide pipe 10 is fixedly connected to the bottom of the feeding bin 9, and the bottom of the No. 2 material guide pipe 10 is connected to the bottom of the mixing barrel 1. A discharge port 11 is excavated at the bottom of the mixing barrel 1, and the discharge port 11 is detachably connected to a flange.

After the material is put, the rotating cover 2 is rotated to rotate the connecting ring 6 at the bottom of the No. 1 guide pipe 5 to the top of the feeding bin 9. The sealing ring 8 is inserted into the feeding bin 9 under the push of the spring 13 to seal the feeding bin 9. When mixing the powder, the servo motor 3 is turned on. As the output end of the servo motor 3 drives the spiral feed rod 4 to rotate, the powder entering the bottom of the mixing barrel 1 through the No. 2 guide pipe 10 is transported upward. When the powder moves to the top, it slides from the No. 1 guide pipe 5 back to the feeding bin 9. During the circulation transportation, the powder is moving to achieve the purpose of mixing. When unloading, the flange at the bottom of the discharge port 11 is opened. Since the spiral feed rod 4 is always rotating, the material is always in a flowing state, avoiding powder accumulation and difficulty in discharging.
