In an embodiment of the invention, the filling mover 6 is any commonly used automated equipment, such as a rectangular robot, an industrial robot, etc., preferably a horizontal articulated robot. The filling mover 6 moves the filling actuator 5 at the moving end thereof to obtain a spatially arbitrary position movement. The fill flip driver 502 of the fill actuator 5 may drive the fill flip vessel 503 either open up or open down. The filling turn-over vessel 503 is upward, and the filling turn-over vessel 503 can contain a metal mixed powder of the metal element species n. The filling turn-over vessel 503 is opened downward, and the metal mixed powder of the metal element species n contained in the filling turn-over vessel 503 is rapidly entered into a cell 701 of the cell array 7 in the opened upward state through the filling fixed point replenishment device 504.
Specifically, when the buffer flip-flop 302 is opened upward, the buffer flip-flop 302 may contain a metal mixed powder of the metal element species n. When the buffer flip-flop 302 is opened downward, the metal powder of the metal element type n contained in the buffer flip-flop 302 falls down, and rapidly enters into the filling flip-flop 503 in the opened upward state through the buffer fixed-point replenishment 4. The purpose of the powder buffer 3 is to allow the metal powder production work of the powder mill 1 and the powder mixer 2 to be parallel to the filling work of the honeycomb array 7 by the filling actuator 5 and the filling mover 6, thereby realizing high throughput execution efficiency. The buffer spot-size compensator 4 is used to pour the metal mixed powder, the metal mixed powder is dispersed to have an area that is several orders of magnitude larger than the area of the honeycomb opening, and in order to prevent the metal mixed powder from being dispersed into the adjacent honeycomb 701, and to cause the alloy components to be disordered, the buffer spot-size compensator 4 is required to compensate for the difference in the number level of the metal mixed powder dispersed area and the honeycomb opening area, and to enable the metal mixed powder to fall into the powder filling actuator accurately at a fixed point.
The invention provides a high-flux preparation device of a honeycomb array high-temperature alloy material, which has the working principle that: the powder mixer 2 mixes and guides n kinds of granular metal powder into a buffer overturning vessel 302 with an upward opening, and the buffer overturning vessel 302 can contain granular metal mixed powder with a metal element kind of n. The buffer flip driver 301 drives the buffer flip vessel 302 to open downwards, and the metal powder contained in the buffer flip vessel 302 rapidly enters the filling flip vessel 503 in an opening-up state through the buffer fixed-point replenishment device 4. The filling mover 6 moves the filling actuator 5 at its moving end to any position in space so that the lower opening of the filling setpoint supplement 504 is aligned within the cell 701 of one of the individual units within the cell array 7. The filling turn-over driver 502 drives the filling turn-over vessel 503 to turn over to the opening-down direction, and the metal powder contained in the filling turn-over vessel 503 is promptly entered into a honeycomb 701 in the opening-up state through the filling set-point replenishment 504.

And in a pulverizing unit, a plurality of pulverizing machines 1 are arranged on one pulverizing machine 2, and the pulverizing machines 2 are used for mixing powder, so that the pulverizing machines 1 can work in parallel, and the pulverizing efficiency is further improved.
