[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0029] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0030] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] Reference below Figure 1-Figure 2 , the implementation of the mixing and feeding device proposed in the embodiment of the utility model is described in detail.

[0032] The mixing and feeding device according to the embodiment of the utility model is suitable for mixing and feeding tungsten powder, and comprises: a support frame 1, a mixing kettle 2, a gas-electric integrated slip ring 3 and an arch-breaking member 4.

[0033] Specifically, there are rotating shafts 21 on both sides of the mixing kettle 2, and the rotating shafts 21 are rotatably connected to the support frame 1 to enable the mixing kettle 2 to rotate in the vertical direction to mix the tungsten powder. The gas-electric integrated slip ring 3 is connected to the rotating shaft 21 to provide an air source for the arch-breaking component 4. The arch-breaking component 4 has a plurality of air discs 41 and a plurality of air hammers 42. The plurality of air hammers 42 and the plurality of air hammers 42 are circumferentially arranged near the discharge port 25 of the mixing kettle 2 to jointly break the tungsten powder in the mixing kettle 2. The gas-electric integrated slip ring 3 is connected to the rotating shaft 21 to provide an air source for the arch-breaking component 4.

[0034] That is to say, in the previous process, the tungsten powder is poured into the mixing kettle 2, and the mixing kettle 2 is rotated in the vertical direction until the tungsten powder is evenly mixed; the gas path at the dynamic end of the mixing kettle 2 is connected to the gas path at the static end of the support frame 1 through the gas-electric integrated slip ring 3 to avoid cluttered gas paths; the mixed tungsten powder is broken by the cooperation of the gas disc 41 and the gas hammer 42 to prevent the tungsten powder from being retained on the inner wall of the mixing kettle 2, thereby discharging the tungsten powder from the discharge port 25 for unloading.

[0035] Thus, the tungsten powder is mixed evenly by rotating the mixing kettle 2 in the vertical direction, and after mixing, the tungsten powder in the mixing kettle 2 is broken and discharged by the arch-breaking member 4, and the dynamic and static ends of the gas path are separated by the gas-electric integrated slip ring 3 to provide a gas source for the arch-breaking member 4, so that the gas path and the rotation of the mixing kettle 2 will not interfere with each other. The mixing and discharging device can fully mix the tungsten powder, has a simple structure, and has a high discharging efficiency.

[0036] As for the opening and closing of the discharge port 25, the discharge port 25 is provided with a butterfly valve 5, which is suitable for opening when feeding to discharge the tungsten powder. It can be understood that the tungsten powder can be sealed and mixed in the mixing kettle 2 by the butterfly valve 5, so as to avoid the tungsten powder being exposed and causing pollution. At the same time, the butterfly valve 5 has little effect on the discharge of the tungsten powder after opening, which is conducive to the rapid discharge of the tungsten powder. Among them, the tungsten powder can be poured into the mixing kettle 2 from the discharge port 25.

[0037] As for the mixing kettle 2, the mixing kettle 2 has a first truncated cone cavity 22, a cylindrical cavity 23 and a second truncated cone cavity 24, which together constitute a mixing space, the rotating shaft is arranged at two opposite sides of the middle position of the cylindrical cavity 23, the feed port is arranged at the end of the first truncated cone cavity 22, and the discharge port 25 is arranged at the end of the second truncated cone cavity 24. It can be understood that the weight of the mixing kettle 2 is evenly distributed at both ends by the arrangement of the first truncated cone cavity 22 and the second truncated cone cavity 24, so that the mixing kettle 2 is more stable when rotating, and the discharge port 25 is arranged at the end of the second truncated cone cavity 24, which can facilitate the discharge of tungsten powder, thereby improving the feeding efficiency; in addition, the cylindrical cavity 23 is arranged so that when more tungsten powder is put in, the main gravity of the tungsten powder is closer to the position of the cylindrical cavity 23, so that the mixing kettle 2 is more stable when rotating and mixing.

[0038] Regarding the arrangement of the gas path, the second truncated cone cavity 24 is provided with a plurality of fixed rings 6, which are arranged circumferentially along the outer surface of the second truncated cone cavity 24 and are arranged near the air inlet end of the arch-breaking member 4. It can be understood that by setting the fixed rings 6, the air pipe or wire is connected from the gas-electric integrated slip ring 3 and then fixed on the fixed rings 6, which is convenient for providing the gas source for the gas disc 41 and the gas hammer 42, and the whole is more neat and simple. Among them, the fixed rings 6 can be welded on the outer surface of the second truncated cone cavity 24.

[0039] Furthermore, a docking flange 7 is included, which is installed on the butterfly valve 5 to dock with the receiving container when unloading. It can be understood that the docking flange 7 can be used to dock with the receiving container when unloading to avoid tungsten powder exposure and pollution during unloading, and can be docked with the entire automated production line, thereby improving the overall efficiency.

[0040] Furthermore, the butterfly valve 5 is a pneumatic butterfly valve 5. It can be understood that since the arch breaking member 4 mainly adopts pneumatic components, the pneumatic butterfly valve 5 can be used to facilitate the simultaneous arrangement of the air pipe, avoid the mixing of wires and air pipes, and make the appearance of the overall device more concise. Among them, the pneumatic butterfly valve 5 has a switch button, which can automatically control the switch of the pneumatic butterfly valve 5 or manually control it.

[0041] Regarding the installation of the air disc 41 and the air hammer 42, the air disc 41 and the air hammer 42 are both installed on the second truncated cone cavity 24 through the reinforcing plate 8. It can be understood that, through the provision of the reinforcing plate 8, the air disc 41 and the air hammer 42 are more firmly installed on the second truncated cone cavity 24, and at the same time, when the air disc 41 and the air hammer 42 are working, it is not easy to cause impact and deformation on the second truncated cone cavity 24. Among them, the reinforcing plate 8 can be welded to the outer surface of the second truncated cone cavity 24.

[0042] In addition, a reinforcing rib 9 is provided at the connection between the rotating shaft 21 and the mixing kettle 2. It can be understood that the provision of the reinforcing rib 9 makes the connection between the rotating shaft 21 and the mixing kettle 2 more secure, thereby preventing the connection between the two from being damaged due to excessive load or long-term rotation. The reinforcing rib 9 can be welded along the circumference of the rotating shaft 21.
