The SZX-308 connected unit's flexographic printing machine and high-speed die-cutting machine replace traditional snowball waste discharge, perfectly cooperating with automatic non-stop equipment for uninterrupted waste discharge, achieving true non-stop production of flexographic printing machines, improving production efficiency and yield. The waste enters the compactor through the conveyor belt and is compressed and extruded, which can reduce the volume of waste, save storage space, and facilitate transportation.
