A stone paper carton processing indentation device

Abstract

The utility model provides a kind of indentation device for stone paper carton processing, the stone paper paperboard used when stone paper carton processing is sequentially conveyed by first conveyor belt, guide roller and second conveyor belt, so that stone paper paperboard is passed through steam softening mechanism, with the conveyance of stone paper paperboard, upper steam injector is aimed at preset indentation line position and emits steam to wet stone paper paperboard, reduce the brittleness of preset indentation line position stone paper paperboard and make its toughness and ductility be improved, and then when stone paper paperboard is conveyed to guide roller, the indentation roller above guide roller rotates, so that the indentation ring corresponding with steam injector above it is set and the preset indentation line of steam softened stone paper paperboard is indented, so as to ensure that stone paper paperboard does not produce rupture when indentation, so as to improve the load capacity and structural stability of the stone paper carton made.
