Abstract
A bottle-mouth package permeability test system includes: a bottle-mouth mold group, a permeation amplifying cavity, a carrier gas assembly, a to-be-tested gas assembly, a pressure regulating assembly, a temperature regulating assembly, and a detection assembly. The carrier gas assembly allows a carrier gas to circulate in the bottle-mouth mold group connected in series on the carrier gas assembly. The to-be-tested gas assembly allows a to-be-tested gas to flow in the permeation amplifying cavity connected in series on the to-be-tested gas assembly. The pressure regulating assembly can regulate pressure states of the carrier gas outputted by the carrier gas assembly and the to-be-tested gas outputted by the to-be-tested gas assembly. The temperature regulating assembly can regulate temperature states of the carrier gas and the to-be-tested gas. The detection assembly is in communication with an exhaust end of the carrier gas assembly.
