Description

Linear injection-blow-filling-sealing integrated plastic bottle packaging equipment

Technical Field

The invention relates to the technical field of plastic bottle forming, in particular to linear plastic bottle packaging equipment integrating injection, blowing, filling and sealing.

Background

Plastic bottles are a common container widely used for medical liquid containers, medical powder containers, medicine containers, beverage containers, seasoning containers, and the like, and thus are in great demand.

The bottle blowing process of the plastic bottle comprises a one-step method and a two-step method, the two-step method bottle blowing is relatively widely applied due to high machine yield, but the one-step method bottle blowing has the advantage in the aspect of energy saving due to the utilization of the residual heat of a bottle blank, and if the yield of the one-step method bottle blowing machine can be improved to reach the level of the two-step method bottle blowing, the advantage is highlighted.

Two representative bottle blowing machines at present are respectively Japanese solid Qingmu and Japanese essence. Wherein, the blue wood adopts disc type three-station, the technological process is blank injection, bottle blowing and bottle discharging; the method adopts a disc type four-station process, and the technological process comprises the steps of blank injection, preheating, bottle blowing and bottle discharging. Although the processes of the two are slightly different, the disc type structure is adopted. However, the disc type structure severely limits the yield of blown bottles, and accordingly affects the yield of plastic bottles.

In addition, the plastic bottle filling and sealing process is often separated from the plastic bottle manufacturing process, so that corresponding sterilization treatment is required before the plastic bottle is filled and sealed, and the problems of incomplete sterilization, impurity introduction and the like are easily caused.

In addition, after the output of the same batch of plastic bottles is increased, how to perform synchronous and stable sealing operation on a plurality of plastic bottles also becomes a problem to be solved.
