[0022] 2.

The transmission shaft drives the second rotating shaft to rotate through the second synchronous belt, and the second rotating shaft drives the cam to rotate, and the roller rolls from the convex section to the concave section, so that the slide bar moves downward under the limit of the slide cylinder, so that the baffle moves downward in the slide groove, and the thin plate is transported by the conveyor belt to the connecting plate of the flap assembly for flipping, and then the roller moves to the convex section, so that the slide bar drives the baffle to move up to block the subsequent thin plates, thereby achieving the effect of accurately positioning the thin plates, intercepting them and transporting them to the connecting plate of the flap assembly for flipping.
