Precautions for operation and maintenance of blow molding machine

In recent years, with the rapid development of the domestic plastic bottle market, the plastic bottle blowing machine industry has ushered in a development opportunity. The blow molding machine is a kind of fully automatic stretch blow molding equipment. In other words, it is a machine used to blow bottles, which obviously means a machine that can blow plastic particles (softened into liquid) or preforms into bottles through a certain manufacturing process. The bottle is made by the bottle blowing machine, so that the subsequent materials are poured into the bottle, which saves time and effort, and the blowing efficiency is high.

At the same time, in the face of rapid market changes, the production of plastic packaging materials is simple and convenient, and food packaging companies can respond flexibly to the shorter and shorter life cycles of packaging materials. As this, blowing machinery is still welcomed by the market. According to the author’s knowledge, a variety of blow molding equipment has appeared on the market, including fully automatic blow molding machines, semi-automatic blow molding machines and other highly automated blow molding machines, which can meet the process needs of different users and greatly improve the blowing Bottle efficiency.
So, how do users operate the bottle blowing machine correctly, and what should be paid attention to for maintenance? According to the technical staff, firstly, it is necessary to place the preform correctly in the preform container, and then manually enter the preform positioning device through the conveying system. Secondly, it is necessary to put the preform mouth up to avoid the appearance of inverted molds, which will affect the quality of the bottle and cause unnecessary waste of plastic packaging materials. Then the preforms are manually loaded onto the preform fixing device to avoid loosening of the preforms during transportation, and then sent to the drying tunnel.
In addition, after the preform is heated, it is also transported to the blowing system. Then place the preheated preform (embryo) into the blow mold (locking), and then go through low-pressure blowing, high-pressure blowing, and exhaust to blow the preform (embryo) to the desired Bottle. Finally, the mold is opened, and after the bottle is formed, the manual demoulding system is used to transport the bottle from the bottle blowing platform. It is worth mentioning that if the fully automatic bottle blowing machine can be operated manually, the process of putting the preheated preheated preform (embryo) into the blow mold is eliminated, and the blowing efficiency is significantly improved.
