Abstract

The utility model discloses a liquid nitrogen cooling blow molding rim charge mechanism and a blow molding processing device, a cooling assembly is placed beside a transmission belt, liquid nitrogen is filled in a liquid nitrogen storage tank, the liquid nitrogen is conveyed to a spray head through a conveying pipeline, the spray head is aligned with the transmission belt in a cooling chamber, blow molding rim charges to be cooled are placed on the transmission belt and are conveyed into the cooling chamber, and the blow molding rim charges are cooled by the spray head. Starting a spray head to atomize liquid nitrogen and uniformly spray the atomized liquid nitrogen on the blow molding rim charge; liquid nitrogen cooling is adopted, so that the cooling time of blow molding rim charges can be greatly shortened, and the production efficiency is improved; in addition, the blow molding rim charge can be quickly shaped due to the ultralow temperature of the liquid nitrogen, deformation and internal stress are reduced, and the material performance is improved; in addition, the liquid nitrogen is inert gas, cannot chemically react with the blow molding rim charge, and is free of residues after vaporization, environment-friendly and pollution-free.
