Problems solved by technology

[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 the bottle body of the plastic bottle can be effectively completed, and the thickness of the peripheral wall of the bottle body is uniform. , high yield

Embodiment Construction

[0018] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0019] The bottle blowing technique of described a kind of plastic bottle comprises the steps:

[0020] The first step: the production of preform mold

[0021] The preform mold is made by injecting molten material into the mold with an injection machine. The powdery or granular plastic is sent from the hopper of the injection machine into the heated barrel. It is compressed and moved forward, through the nozzle at the front of the barrel, it is injected into the closed mold cavity with low temperature at a fast speed, after a certain period of cooling and shaping, the mold is opened to obtain the product;

[0022] The second step: choose an integrated bottle blowing machine,

[0023] The upper...

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.
