Patent ID: 6939498

Claim:
A method for manufacturing a crystallized bottleneck of a polyester beer bottle, comprising the steps of: forming a blank of a bottle made of polyester material through drying; ejecting the polyester material and shaping said ejected polyester material through cooling, thereby forming an uncrystallized blank of a bottle; placing the uncrystallized blank of the bottle for 24-72 hours in an air-conditioned environment; preheating a crystallizer for at least two hours prior to crystallizing the blank of the bottle; loading a bunker with the uncrystallized blank of the bottle; delivering to an blank horse's head via a conveyor belt; sending a bottleneck portion of the uncrystallized bottle blank into said crystallizer to heat the bottleneck portion at a high temperature and crystallize the bottleneck portion via an arbor transmission chain; at the same time, controlling the temperature of the uncrystallized portion of the blank body, so that the uncrystallized portion of the blank body is not affected by the high temperature environment of the crystallizer; discharging the polyester bottle blank through an output blank horse's head; and delivering to another conveyor belt to cool and shape the polyester bottle blank.
