[0003] The original roll-to-roll circular knife die-cutting process or hydrogen energy MEA packaging process adopts roll-to-roll material shaft unwinding. A lot of materials are used. The basic unwinding layout is up and down and on both sides (unwinding material shaft), parallel to the die-cutting knife seat, for compounding and die-cutting of multi-layer materials. When the roll material put into the material shaft is used up, it is necessary to manually stop the equipment and enter the equipment to replace the material roll, and manually tape the head and tail of the new and old rolls to complete the material replacement action.

[0004] Existing die-cutting equipment has the following problems: 1. The material strip unwinding adopts an up-and-down layout, and the material cannot be discharged from the lateral side of the die-cutting equipment, which is constrained by the space of the production line and poses a safety hazard to the operator. 2. The waste strip after discharge is often tangled into a ball, which brings difficulties to subsequent processing. Summary of the invention
