[0014] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0015] like Figures 1 to 4 As shown, an embodiment of the present invention provides a uniform feeding machine structure for aluminum nitride powder, including a feeding body 1, a stirring assembly 2, a heating assembly 3, a feeding cylinder 4, and a feeding component 7.

[0016] This utility model provides a uniform aluminum nitride powder feeding machine structure. Through the arrangement of the stirring component 2 and the heating component 3, heat conduction and stirring of the aluminum nitride powder inside the feeding cylinder 4 are achieved, ensuring uniform heating and preventing the aluminum nitride powder from becoming damp, condensing, and sticking to the inner wall of the feeding cylinder 4. The arrangement of the feeding cylinder 4, pressure valve 5, feeding valve 6, and feeding component 7 allows for the control of aluminum nitride powder discharge inside the feeding cylinder 4 through negative pressure adsorption, ensuring uniform discharge of aluminum nitride powder and preventing excessive or insufficient discharge, thus improving the manufacturing effect of the mechanical equipment.

[0017] In this embodiment of the invention, during use, aluminum nitride powder is poured into the feeding cylinder 4, the stirring motor 22 is energized and started, and the output power drives the stirring rod 24 through the stirring shaft 23 to stir the aluminum nitride powder. At the same time, the heating rod 32 is energized to heat the liquid inside the heating box 31. Then, the delivery pump 33 is energized and started to transport the heated liquid through the delivery pipe 34, so that it conducts heat to the aluminum nitride powder inside the feeding cylinder 4, heats it, and keeps the aluminum nitride powder dry. When it is necessary to discharge the powder, the exhaust pump 72 is energized and started to discharge the air inside the feeding box 71. Then, the discharge valve 6 is opened. Due to the negative pressure inside the feeding box 71, the pressure valve 5 is opened, so that the aluminum nitride powder in the feeding cylinder 4 falls into the feeding box 71 under the action of gravity. When the pressure inside the feeding box 71 is the same as the external pressure, the pressure valve 5 will close, thereby enabling quantitative discharge of aluminum nitride powder and reducing the situation of too much or too little aluminum nitride powder being discharged during the manufacturing of mechanical equipment.

[0021] like Figure 3 and Figure 4As shown, in a further embodiment of this utility model, the feeder 41 is funnel-shaped, and a first discharge hole is provided on the end face of the feeder 41, which is connected to the pressure valve 5; the funnel-shaped feeder 41 allows the aluminum nitride powder inside the feed cylinder 4 to be subjected to gravity, resulting in good discharge efficiency. Figure 4 As shown, in a further embodiment of this utility model, the feeding hopper 73 is funnel-shaped, and a second feeding hole is provided on the end face of the feeding hopper 73. The second feeding hole is connected to the discharge valve 74, and an exhaust pipe is fixedly connected to the end face of the exhaust pump 72.
