The invention relates to a label peeling machine. The machine comprises a machine shell, a label peeling assembly, a label supporting mechanism and a film pressing device; the label peeling assembly is used for separating a bottom film and a label; the label supporting mechanism is used for bearing the label separated out of the bottom film; the film pressing device is used for pulling the bottom film and comprises an active film pulling mechanism and a movable film pressing mechanism opposite to the active film pulling mechanism, when the movable film pressing mechanism and the active film pulling mechanism are in abut joint, the active film pulling mechanism runs to pull the bottom film to peel the label, and when the movable film pressing mechanism and the active film pulling mechanism are separated, the active film pulling mechanism stops pulling the bottom film; due to the fact that the label peeling assembly and the film pressing device are arranged, the film pressing device automatically pulls the bottom film to move, in the process of the bottom film movement, the label peeling assembly successfully peels the label from the bottom film, the label cannot be damaged, the peeled label reaches a label supporting plate to be attached to an electronic product, and the label peeling machine obviously improves the peeling efficiency and peeling quality of labels.
