This invention relates to an integrated clean packaging machine for scallion processing, comprising a frame, a directional sorting mechanism, a flexible transfer mechanism, a waterless clean treatment module, a compact bundling and weighing module, and a controller. The directional sorting mechanism uses a crank-rocker to drive a wedge-shaped pusher plate in conjunction with a flexible brush, achieving orderly output of individual scallions. The flexible transfer mechanism utilizes a multi-degree-of-freedom robotic arm combined with a photosensitive device to grasp and transfer scallions. The waterless clean treatment module uses a spring-driven adaptive friction sliding cover reciprocating motion to remove dead skin and dirt from the scallion surface through radial friction. The compact bundling and weighing module integrates automatic film feeding, circumferential bundling, electrothermal film cutting, and automatic weighing functions. This invention solves the problems of easy jamming during scallion processing, reliance on manual single-scallion feeding, easy spoilage due to water washing, and poor brush cleaning effect in existing technologies, achieving efficient, non-destructive, and low-energy fully automated clean processing of scallions.
