This utility model discloses a high-speed rewinding device, including an unwinding
assembly. The device is characterized by: a rotating disk (4) located near the
discharge end of the unwinding
assembly; an air shaft (3) arranged around the rotating disk (4); a pressing
assembly located corresponding to the
discharge end of the unwinding assembly; the pressing assembly pressing the unwound substrate tightly onto the air shaft (3) for winding; a
cutting assembly located corresponding to the winding
station to
cut the wound substrate; the rotating disk (4) driving the wound air shaft to rotate to the
discharge station; and a labeling assembly and a pushing assembly located corresponding to the discharge
station. This utility model has a simple structure and reasonable design, allowing direct rewinding and collection of the substrate on the air shaft without the need for paper core assembly, simplifying the rewinding process and improving rewinding efficiency.
