For example, the metal powder mixing equipment currently on the market usually adopts traditional physical mixing methods, which have low mixing accuracy and make it difficult to achieve uniform powder mixing, resulting in unstable material properties and low production efficiency in some scenarios.

[0003] The above problems indicate that traditional metal powder mixing equipment currently on the market is unable to effectively meet the new requirements for high precision and uniform mixing under complex formulations.

[0021] The present invention will be further described in conjunction with the following embodiments.

[0022] Example 1:

[0023] like Figure 1-3 As shown, a metal powder mixing device includes a mixing chamber 1, a multi-stage mixing mechanism, and an intelligent flow regulation mechanism. The mixing chamber 1 is the core component of the entire device, with a feed inlet 2 at the top and a discharge outlet 3 at the bottom for inputting and outputting metal powder. A drive motor 4 is installed through the top of the mixing chamber 1, and the drive motor 4 is connected to the multi-stage mixing mechanism via a coupling, thereby driving the multi-stage mixing mechanism to rotate inside the mixing chamber 1. An intelligent flow regulation mechanism is also provided on the upper part of the mixing chamber 1, which is connected to the mixing chamber 1 via a feeding channel 12 and is used to control the feeding speed and sequence of different types of metal powder. The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] The multi-stage mixing mechanism mainly includes a rotating shaft 5, stirring blades 6, layered guide plates 7, and turbulence-inducing components 8. The rotating shaft 5 passes through the top of the mixing chamber 1 and extends into the interior of the mixing chamber 1. Its top is fixedly connected to the output shaft of the drive motor 4. When the drive motor 4 starts, the rotating shaft 5 rotates accordingly. The stirring blades 6 are installed at the bottom of the rotating shaft 5. The stirring blades 6 are designed with an arc-shaped structure, which can effectively improve the flowability of metal powder at the bottom of the mixing chamber 1 and avoid material accumulation. The layered guide plates 7 are sleeved in the middle of the rotating shaft 5. The layered guide plates 7 are distributed along the axial direction of the rotating shaft 5 and are used to divide the internal space of the mixing chamber 1 into multiple layers, thereby realizing multi-level mixing processing. Two sets of turbulence-inducing components 8 are installed on the layered guide plates 7, and each set of turbulence-inducing components 8 is sleeved with elastic turbulence-inducing plates 9. The design of the elastic baffle 9 has a certain degree of flexibility, allowing it to contact the inner wall of the mixing chamber 1 during rotation, thereby creating a turbulent effect on the metal powder and further improving the mixing uniformity. In addition, limit rings 19 are installed at both the upper and lower ends of the elastic baffle 9. The function of the limit rings 19 is to prevent the elastic baffle 9 from shifting or falling off during high-speed rotation. Wear-resistant pads 20 are also installed on the limit rings 19 near the bottom of the elastic baffle 9 to reduce frictional loss between the elastic baffle 9 and the inner wall of the mixing chamber 1, extending the service life of the equipment. A buffer section 17 is set in the center of the rotating shaft 5. A shock-absorbing spring 18 is installed inside the buffer section 17. The shock-absorbing spring 18 can absorb vibration energy during equipment operation, reduce equipment operating noise, and protect the rotating shaft 5 from excessive impact.

[0025] The intelligent flow regulation mechanism mainly includes a flow sensor 10, a regulating valve group 11, and an electrically controlled valve 15. The flow sensor 10 is installed at the inlet of the regulating valve group 11 to monitor the flow rate of the metal powder in real time and transmit the monitoring data to the control system via the signal line 13. The top of the regulating valve group 11 is provided with metal powder inlets 14 to receive metal powder raw materials from different storage devices. The bottom of the regulating valve group 11 is connected to the feeding channel 12, through which the metal powder enters the mixing chamber 1. The bottom of the regulating valve group 11 is provided with electrically controlled valves 15, and metal powder flow regulating plates 16 are installed on the electrically controlled valves 15. The metal powder flow regulating plates 16 are inserted into the inner wall of the regulating valve group 11. By adjusting the opening and closing degree of the metal powder flow regulating plates 16, the feeding speed of different metal powders can be precisely controlled. The electrically controlled valves 15 are connected to the control system. The control system dynamically adjusts the opening degree of the electrically controlled valves 15 according to the data fed back by the flow sensor 10, thereby realizing real-time monitoring and dynamic adjustment of the metal powder feeding process.

[0026] In practical applications, the working principle of this invention is as follows: First, different types of metal powder raw materials are loaded into their respective storage devices. The storage devices are connected to the metal powder inlet 14 via pipes. After the equipment is started, the control system opens the electrically controlled valves 15 in the regulating valve group 11 according to the preset formula ratio, allowing different types of metal powder to enter the mixing chamber 1 through the feeding channel 12 at a set speed. During this process, the flow sensor 10 monitors the feeding flow rate of each type of metal powder in real time and transmits the monitoring data to the control system. If the feeding flow rate of a certain type of metal powder deviates from the set value, the control system will automatically adjust the opening of the corresponding electrically controlled valve 15. Until the feed flow rate returns to the set range, the drive motor 4 starts, driving the rotating shaft 5 and its stirring blades 6, layered guide plates 7 and turbulence components 8 to rotate. The stirring blades 6 perform preliminary mixing of the metal powder at the bottom of the mixing chamber 1. The layered guide plates 7 guide the metal powder to different layers. The elastic turbulence plates 9 on the turbulence components 8 further improve the mixing uniformity by turbulently turbulent the metal powder. During the mixing process, the friction generated by the contact between the elastic turbulence plates 9 and the inner wall of the mixing chamber 1 is effectively relieved by the wear-resistant pads 20, thereby extending the service life of the equipment. When the mixing is completed, the uniformly mixed metal powder is discharged through the discharge port 3, completing the entire mixing process.

[0027] This invention achieves high-precision and uniform mixing of complex metal powder formulations through the coordinated operation of an intelligent flow regulation mechanism and a multi-stage mixing mechanism. The intelligent flow regulation mechanism can monitor and dynamically adjust the mixing process in real time, significantly improving mixing accuracy and reducing the need for manual intervention. The multi-stage mixing mechanism, through the multi-layer mixing treatment of stirring blades 6, layered guide plates 7, and turbulence components 8, ensures thorough mixing of metal powder within the mixing chamber 1. Furthermore, the design of the buffer section 17 and shock-absorbing spring 18 in the center of the rotating shaft 5 effectively reduces vibration and noise during equipment operation, improving the stability and reliability of the equipment. The design of the limiting rings 19 and wear-resistant pads 20 at the upper and lower ends of the elastic turbulence plate 9 further enhances the durability of the equipment, enabling it to adapt to long-term, high-intensity production requirements. In summary, this invention not only meets the high-precision mixing requirements of complex metal powder formulations but also features high efficiency, stability, and durability, making it suitable for various metal powder processing scenarios.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
