The invention relates to an unformed adaptive discharging mechanism which comprises a base, and is characterized in that at least one roller shaft group is arranged on the base and comprises a left roller shaft and a right roller shaft; the left roller shaft and the right roller shaft rotate in opposite directions. The unformed adaptive discharging mechanism has the benefits that 1, the left roller shaft and the right roller shaft rotate in opposite directions, so that parts between the left roller shaft and the right roller shaft are automatically arranged to a column so as to be conveyed, precision discharging is realized, and the problem that a conventional structure cannot precisely execute discharging by a vibration mode; 2, a vibrator is matched with a V-shaped material trough, and uniform part arrangement is facilitated; 3, by the use of a front vibration stick, a large stack of parts can be effectively scattered, and the precision is improved; 4, the left roller shaft and the right roller shaft are meshed, so that the parts can be prevented from falling off a clearance during conveying.
