TECHNICAL FIELD The present invention relates to a food forming method and a forming mechanism, belonging to the field of food processing. BACKGROUND In the field of food processing, forming machines are often used for food processing. But for rolled foods such as spring rolls, because of their unique structure and shape, there is no automated forming equipment so far, and the rolls are still manually packed, which renders not only a low efficiency and relatively high personnel cost, but also a poor yield at times due to various specifications of the hand-rolled food. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a food forming method and a forming mechanism capable of automatically forming a rolled food. In order to achieve the above object, a food forming method of the present invention comprises: placing a food blank containing a wrapping skin on a supporting part;folding two sides of the food blank by two oppositely arranged turning parts, the food blank being clamped by a clamping mechanism formed by at least one of the turning parts and the supporting part;driving the clamping mechanism to rotate to form the food blank into a rolled food; anddriving the clamping mechanism to move in a direction away from the rolled food so that the clamping mechanism is drawn out from the rolled food. The present invention also provides a food forming mechanism, comprising: a supporting part configured to support a food blank on a forming station;two turning parts, which are oppositely arranged and configured to fold two sides of the food blank, wherein at least one of the turning parts cooperates with the supporting part to form clamping mechanism for clamping the food blank;a turning driving device configured to drive the turning part to reverse;a rotation driving mechanism configured to drive the clamping mechanism to rotate so as to form the food blank into a rolled food; anda drawing driving mechanism configured at least to drive the clamping mechanism to move in a direction away from the rolled food so that the clamping mechanism is drawn out from the rolled food. By using the food forming method and the forming mechanism of the present invention, the food blank can be folded by mechanical automation equipment, and then be rotated to form the rolled food, which can effectively improve the food processing efficiency, reduce labor costs, and enhance the controllability of the processing quality.
