Plastic bottle blowing process

Abstract

The invention discloses a plastic bottle blowing process. The process comprises the following steps that a preform mould is manufactured; an integrated bottle blowing machine is selected; a preform automatic feeding mechanism is arranged; a preform star wheel is arranged on the integrated bottle blowing machine; preforms are fed into a heating mechanism, and the preforms are heated; then the preforms are fed into the bottle blowing machine; and bottle blowing operation is performed, the preheated preforms are placed in the well made mould, high-pressure air inflation is performed on the interior of the mould, the preforms are taken out of the bottle blowing machine, bottle product detection is performed, and qualified products are counted by a counting system and then guided into a finished product box. According to the plastic bottle blowing process, the process steps are reasonable in design, capable of saving energy, and efficient.

Description

technical field [0001] The invention relates to the field of plastic bottle body blowing processing, in particular to a plastic bottle blowing process. Background technique [0002] PET is the abbreviation of polyethylene terephthalate. The plastic material of PET is a polymer produced by the combination of terephthalic acid and ethylene glycol. PET plastic is light in weight, high in transparency, impact resistant and not easy to break and other characteristics, PET plastic bottles are widely used in daily necessities, daily chemical packaging, health care, beverages, mineral water, reagents and other fields. This kind of bottle has a large social demand, and the existing processing technology is complicated, and it is easy to produce preforms during processing. The bottom is whitish, and the surface thickness of the finished product is uneven. Therefore, the present invention provides a plastic bottle blowing process. The process design is reasonable, and the processing of...
