Background

Plastic bottles are a common container, and are widely used for medical liquid containers, medical powder containers, medicine containers, beverage containers, seasoning containers, etc., and thus are very large in demand.

The bottle blowing process of plastic bottles is divided into a one-step method and a two-step method, and the two-step method is relatively wide in application because of high machine yield, but the one-step method has advantages in energy saving because of utilizing the residual temperature of bottle blanks, 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 advantages are obvious.

In addition, the plastic bottle filling and sealing process is often separated from the plastic bottle manufacturing process, so that corresponding sterilization treatment is needed before filling and sealing of the plastic bottle, and the problems of incomplete sterilization, impurity introduction and the like are easy to occur.

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