[0012] A feeding method of a granular heating non-combustible tobacco solid high-speed ordered feeding mechanism, comprising the following steps:

[0013] Step S1: When the solid (4.3) in the solid enclosure (3.4) of the feeding mechanism is insufficient, the material level control sensor sends a material signal to the solid lifter, and the solid lifter acts after receiving the signal. The motor drives the equidistant strip belt to step by one unit, and the solid in the equidistant strip belt on the solid lifter falls into the upper hopper discharge port;

[0014] Step S2: At the same time, the negative pressure suction system is started, the first cylinder drives the air sealing plate to open, the negative pressure channel is connected, the solid is sucked into the negative pressure cavity in the negative pressure suction system, and one suction is completed; then the second cylinder drives the blocking plate to rotate, the lower discharge port of the negative pressure cavity is opened, and the solid falls into the solid enclosure through the wall-mounted hopper;

Mainly, according to the cylindrical characteristics of the firmware and the feeding drum wheel groove, the first level of screening reciprocating push rod is used for high-speed linear reciprocating movement to push down the firmware standing on the surface of the feeding drum wheel groove, the second level of high-speed rotating roller is used for rotating and removing the firmware in the feeding drum wheel groove beyond the surface of the feeding drum wheel groove back to the firmware surround, then the third level of high-speed rotating roller is used for gradually and orderly arranging the firmware in the feeding drum wheel groove, and finally 0-7 firmwares in the feeding drum wheel groove are arranged in order from inside to outside under the blowing action of compressed air. At this time, the firmware has been arranged from disorder to order. When the feeding drum wheel rotates to the transfer drum wheel connection position, the first firmware arranged in the innermost position of the feeding drum wheel groove is transferred to the firmware transfer drum wheel groove. After the firmware in the transfer drum wheel groove corresponds to the empty cigarette tube of the empty cigarette tube drum wheel, the preparation work for being filled into the empty cigarette tube is completed. The remaining 0-6 firmwares in the feeding drum wheel groove are returned to the firmware surround with the feeding drum wheel, and the work flow of feeding the firmware from disorder to order is completed. Then the next action cycle is repeated according to the work flow, so that the problem of feeding the firmware from disorder to order and then to order after a series of high-speed arrangement is effectively solved, and the demand for automatic production of high-speed and precise filling of the filling machine is met.
