[0002] A bottle blowing machine refers to a machine for blowing bottles. The most simple explanation is that it is a machine that can blow plastic particles (softened into liquid) or finished bottle embryos into bottles through certain process means. The bottle blowing machine is convenient and fast, and has a large molding volume. After its appearance, it replaced most manual bottle blowing and was adopted by most beverage companies.

[0003] During the processing of the bottle blowing machine, the preform is generally placed in the mold and then the bottle is blown. However, in the prior art, the traditional bottle blowing machine has the following defects. For example, during use, the temperature of the preform is generally high. After the bottle blowing is completed, if it is not cooled in time, the molding effect will be poor and the shape cannot be quickly fixed. The traditional cooling method mostly adopts natural cooling, and the cooling efficiency is poor. Therefore, the utility model proposes a PET high-speed fully automatic bottle blowing machine to solve the above problems. Utility Model Content
