the servo motor drives the V-shaped groove disc and the short shaft to rotate 180 degrees, the propulsion disc assembly is not moved, the short shaft rotates on the propulsion disc assembly in a friction mode, and the short shaft is turned upside down; then the piston rod of the propulsion cylinder retracts into the propulsion cylinder body, and the propulsion disc leaves the short shaft;

the short shaft falls to the working edge of the flat belt through the blanking hole along the V-shaped groove, and the left anti-falling door II, the right anti-falling door II and the material baffle plate surround the short shaft to prevent falling; the striker plate is provided with a second in-place sensor, and the detection area of the second in-place sensor is a space surrounded by the second left anti-falling door, the second right anti-falling door and the striker plate;

when the in-place sensor II detects that a short shaft exists in the area, the electric control system enables the supporting plate cylinder piston rod to retract into the supporting plate cylinder body, the supporting plate cylinder piston rod simultaneously pulls the left rope and the right rope, the left rope and the right rope respectively pull the left hanging pin and the right hanging pin of the ropes, the left anti-falling door II and the right anti-falling door II respectively rotate around the left anti-falling door shaft II and the right anti-falling door shaft II to overcome the elastic tension of the elastic piece II, the opposite side of the two-phase connecting edge of the left anti-falling door II and the left anti-falling door shaft is separated from the opposite side of the two-phase connecting edge of the right anti-falling door II and the right anti-falling door shaft, and a channel is reserved in; the working edge of the flat belt is driven by the flat belt motor to translate from back to front, and the short shaft is conveyed to the second tapping machine along with the translation from back to front.

2. The automatic short shaft feeding, overturning and returning device for the medical incubator of claim 1, wherein the first elastic member or the second elastic member is an industrial rubber spring, a polyurethane spring or a metal coil spring.
