Description

Bottle blowing machine forming mechanism capable of automatically breaking off water gap

Technical Field

The utility model relates to the technical field of plastic package processing equipment, in particular to a bottle blowing machine forming mechanism capable of automatically breaking off a water gap.

Background

In the production process of plastic bottles, plastic particles are often processed into a continuous tube shape by an injection molding machine, and then the tube is placed in a blow molding mold for blow molding operation to form bottle blanks. Because the tubular material for blow molding is longer than the blow mold, redundant material, commonly called a "water gap", is formed at the upper and lower ends of the preform.
