The bowl-shaped stopper sorting mechanism according to claim 1, characterized in that: The arc-shaped material channel structure includes: an arc-shaped material channel (19), a mounting support plate (28), and a material-blocking cylinder (29); The arc-shaped material channel (19) is mounted on the upper right side of the base plate (1) via a mounting plate (28); The arc-shaped material channel (19) is an arc-shaped structure. Its horizontal inlet end is provided with a material groove for receiving the bowl-shaped plug pushed by the secondary picking end push structure. The bowl-shaped plug is pushed into the arc-shaped material channel (19) by the picking end push structure. The bowl-shaped plug falls down along the vertical outlet of the arc-shaped material channel (19) and enters the next process. The material blocking cylinder (29) is fixedly mounted on the bottom end of the base plate (1), and its cylinder rod points to the vertical outlet of the arc-shaped material channel (19) to block the bowl-shaped plug falling from the arc-shaped material channel (19).
