The driving device is mounted to one side of the label separation device. The label separation device is formed of a rotary shaft, a combination-type cutter unit, and an adjustable nail unit. The combination-type cutter unit is installed to the rotary shaft. The adjustable nail unit surrounds the combination-type cutter unit. A label-separation interval is formed between the combination-type cutter unit and the adjustable nail unit. The combination-type cutter unit includes a circular or polygonal cross-section. The adjustable nail unit includes label separating bolts. Each of the label separating bolts includes an adjustable fixed needle. The adjustable nail unit also includes a slide rail formed of concavities and convexities opposite to the concavities.
