Description

Technical Field

[0002] A bottle blowing machine refers to a machine for blowing bottles. The simplest explanation is a machine that can blow plastic particles or preforms into bottles through certain technological means. The bottle blowing machine is convenient and fast, with a large production volume. After its appearance, it has replaced most manual bottle blowing and is adopted by most production enterprises.

[0003] However, when the bottle blowing machine blows the preform, since the preform is heated, during the bottle blowing process, the preform will stick to the mold. After the preform is blown and formed into a plastic bottle, the plastic bottle cannot be automatically unloaded. Workers need to manually take out the plastic bottle from it for unloading, which reduces the bottle blowing efficiency of the preform. At present, the mold and the mold shell often adopt a fixed connection method such as bolts and nuts. When replacing, the bolts and nuts need to be unscrewed, and then the mold needs to be replaced and fixed, which is rather cumbersome. Therefore, it does not meet the existing requirements. For this reason, we propose a plastic bottle blowing machine. Content of the Utility Model
