10. The use method of the stable packaging machine for packaging low-temperature freeze-dried green plums according to claim 1, wherein the stable packaging machine comprises: the method comprises the following steps:

s100: and a rough weighing link: utilize inlet pipe (603) to place the green plum trunk in holding seat (605), start first motor (604), first motor (604) rotation drive holds seat (605) and rotates, inside the green plum trunk gets into ring (607) automatically, under the effect of baffle (606), ensure that the green plum trunk volume of ring (607) inside is roughly the same, hold seat (605) and drive ring (607) and remove to feed opening (608) when, the green plum trunk of ring (607) inside that corresponds can pass through feed opening (608) automatic whereabouts.

S200: ring section of fine weighing: the automatic top that gets into to weighing plate (702) that runs through framework (701) of the dried green plum of whereabouts, weighing sensor (10) carry out the operation of weighing to the dried green plum, and with data transmission to controller (4), if weight is qualified, controller (4) direct start first electric putter (703) promote weighing plate (702) and drive the dried green plum downstream, if weight is lighter, controller (4) then start second motor (803), second motor (803) rotate and drive stirring roller (802) and drive the dried green plum whereabouts, if weight is great, controller (4) then start arm (903) operation, arm (903) are got unnecessary dried green plum to collecting box (902) in.

S300: and (3) packaging: the green plum that finishes of weighing runs through buffer structure (5), buffer structure (5) reduce the potential energy of gravity of the dry whereabouts of green plum, limiting plate (302) carry out the shaping to the wrapping bag on blowing roller (301) surface, the side of wrapping bag is carried out the banding in heat-seal limit structure (2) of top, the green plum is then got into to the wrapping bag under the guide of guide board (303), heat-seal limit structure (2) of below are packed the wrapping bag, when cutting knife (204) accomplishes the banding simultaneously, cut, accomplish the packing operation.
