The invention discloses a use method of an automatic peeling machine. The use method specifically comprises the following steps of: 1. performing feeding: in a feeding area C, placing materials between a core clamper and a quincunx core clamper, and tightly clamping the materials under the effect of axial elastic force generated when elastically expanding, contracting and rotating the quincunx core clamper in the axial direction; 2. performing transportation: using a feeding and discharging device to drive the materials to rotate to a peeling area A; 3. performing peeling; 4. performing outputof the materials; and 5. performing re-feeding and recycling the steps of 1-5. Through the adoption of the use method, labor intensity is reduced, work efficiency is improved, and automatic production of peeling materials such as roots, stems and fruits is achieved.
