1. A roll replacing device, comprising:
an unwinding mechanism comprising a sliding bracket and an unwinding assembly mounted on the sliding bracket; the sliding bracket is configured to controllably move along a first direction, and the unwinding assembly is used for outputting a working material strip and a spare material strip;
a first fixing mechanism provided on the sliding bracket and located downstream of the unwinding assembly, capable of controllably fixing the working material strip and the spare material strip output from the unwinding assembly;
a second fixing mechanism arranged downstream of the first fixing mechanism to form a strip connection station between the first fixing mechanism and the second fixing mechanism, the second fixing mechanism capable of controllably fixing the working material strip and the spare material strip passing through the first fixing mechanism; wherein the working material strip and the spare material strip located between the first fixing mechanism and the second fixing mechanism are arranged at intervals along the first direction;
a cutting mechanism used for cutting off the working material strip and the spare material strip at the strip connection station; and
a strip connection mechanism arranged corresponding to the strip connection station;
wherein the first fixing mechanism is capable of following the sliding bracket to move along the first direction until the spare material strip fixed by the first fixing mechanism and the working material strip fixed by the second fixing mechanism are aligned at the strip connection station, and allows the strip connection mechanism to connect the working material strip and the spare material strip which are aligned at the strip connection station.
