The rotary feeding valve 5 is a conventional mature technology, and the structure thereof is not described herein again.
The dispersing device 3 is used for dispersing the encrypted light powder 100 so as to form powder with uniform particles, and the powder is convenient for subsequent packaging and feeding.
In the dispersing device 3, the powder passing between the roller bodies 21 is physically extruded, compacted and encrypted by the two opposite rotating roller bodies 21, so that the light powder 100 is prevented from drifting away when being fed and the feeding effect is prevented from being influenced.
In order to further increase the bulk density of the light powder 100, the present embodiment further provides a preferred embodiment for the negative pressure system and the positive pressure purging system:

When the roller 21 continues to rotate and the positions of the first chamber 211 and the second chamber 212 are switched, a positive pressure region is formed in the first chamber 211, and a negative pressure region is formed in the second chamber 212, as described above.
In order to form the negative pressure chamber and the positive pressure chamber in the inner space of the roller body 21, as an alternative embodiment, referring to fig. 1, the negative pressure system comprises a suction device, and the suction device is communicated with the chamber at the upper part of the roller body 21 to make the inner part of the roller body be negative pressure; the positive pressure purging system includes an air inlet device, and the air inlet device communicates with a chamber located at the lower portion of the roll body 21 so that the inside thereof is at a positive pressure.

In order to ensure that the first chamber 211 and the second chamber 212 can be switched between the negative pressure interval and the positive pressure interval with the rotation of the roller body 21, this embodiment provides an alternative embodiment, as shown in fig. 3 and 4:
the encryption device 2 further includes: a rotating shaft 22 connected with a driving device and used for driving the roller body 21 to rotate; the driving device can adopt a motor 24 and a speed reducer which are connected, the output shaft of the motor is connected with the rotating shaft 22 through a coupling, the driving devices of the two roller bodies 21 are mutually independent, namely, the two roller bodies 21 independently run and move relatively, and the gap between the two roller bodies can realize the purpose of extruding and encrypting the light powder 100, as shown in fig. 2 and 3;
the encryption device further includes a positive and negative pressure connection member 23 which is provided at the other end of the rotation shaft 22 and allows the rotation shaft 22 to be rotated therein; wherein:

As shown in fig. 3 and 4.
To this end, in the present embodiment, the air extracting device (vacuum pump 6), the chamber (first chamber or second chamber) located at the upper part of the roller body and connected with the air extracting device, the corresponding pipeline, the positive and negative pressure connecting assembly, and the like form a negative pressure system; the positive pressure system is composed of an air inlet device (compressed gas tank 7), a chamber (a first chamber or a second chamber) which is positioned at the lower part of the roller body and connected with the air inlet device, corresponding pipelines, a positive pressure connecting component and a negative pressure connecting component.
In order to facilitate control of the positive and negative pressure regions and increase the pressure difference effect, as an alternative embodiment, each of the first chamber 211 and the second chamber 212 includes a plurality of cells independent of each other, the number of the first conduits 261 corresponds to the number of the cells in the first chamber 211, and each of the first conduits 261 is communicated with its corresponding cell; the number of second conduits 262 corresponds to the number of cells in the second chamber 212 and each second conduit 262 communicates with its respective cell.

When the size of the grid cavity in the first cavity is increased, the positive pressure interval is increased, and the negative pressure interval is reduced; the reverse is true.
When the three cells in the first cavity rotate to the upper part of the roller body 21, the three cells in the second cavity are located at the lower part, the vacuum pump 6 sucks air from the pipeline communicated with the first cavity through the air suction port 231 in the positive and negative pressure connecting assembly 23, the compressed gas tank 7 inflates the pipeline communicated with the second cavity through the air inlet 232 in the positive and negative pressure connecting assembly 23, the two parts work to ensure that the two parts do not affect each other, in other words, the upper part and the lower part in the inner space of the positive and negative pressure connecting assembly 23 are sealed.
