Working steps of bottle blow moulding machine

The bottle blow moulding machine is a very useful machine for producing plastic beverage bottles. Once launched, it was widely welcomed by the market. The bottle blow moulding machine greatly improves the production efficiency and quality of plastic beverage bottles. Many people are interested in bottle blow moulding machine. This article will introduce you to the working steps of bottle blow moulding machine and let you have a better understanding of it.

1. Working steps of bottle blow moulding machine

The working steps of the bottle blow moulding machine are very simple. First place the preform in a suitable container, and the conveying device will send it to the preform positioning device. The bottle blow moulding machine will automatically load the preform onto the fixed container and send it to the heating and drying tunnel. After heating, the bottle blow moulding machine will lock the mold, and then perform low-pressure blowing and high-pressure blowing. After the bottle blow moulding machine is exhausted, the finished plastic bottle is taken from the bottle blowing platform by the automatic demoulding system.

2. Explanation of the key working steps of bottle blow moulding machine

bottle blow moulding machine is a machine that blows plastic particles softened into liquid or finished preforms into bottles through certain technological means. So bottle blowing is a very important step.

Bottle blowing is a two-way stretching process. In this process, the PET chain is extended and arranged in two directions, thereby increasing the mechanical properties of the bottle wall, improving the tensile, tensile and impact strength, and has a good gas Tightness. Although stretching helps to increase the strength, it should not be overstretched. The stretch-inflation ratio should be controlled: the radial direction should not exceed 3.5 to 4.2, and the axial direction should not exceed 2.8 to 3.1. The wall thickness of the preform should not exceed 4.5mm.

3. Matters needing attention in the work of bottle blow moulding machine

The working steps of the plastic bottle blowing machine are simple and the processing speed is very fast. But every step must be well coordinated. Stretching and pre-blowing determine the overall distribution of the material and the quality of the bottle blowing. Therefore, before operation, you need to adjust the stretching start timing, stretching speed, pre-blowing start and end timing, pre-blowing pressure, pre-blowing flow, etc. Blowing is carried out between the glass transition temperature and the crystallization temperature, generally controlled between 90 and 120 degrees. In this temperature range, PET behaves in a highly elastic state and can be quickly formed. After cooling and setting, the preform can become a transparent bottle. In order to make the bottle blow moulding machine work better, please remember to lubricate the moving parts of the bottle blow moulding machine in time. We recommend that you add lubricating oil to the swing arm once every 3-4 days. The large and small chains of the heating machine can be lubricated once a month. Before the bottle blow moulding machine is officially working, please remember to check whether the moving parts of the PET bottle blower are firm and whether the screws are loose or falling off, especially where the impact force is strong. Be sure to check for any abnormalities. Only in this way can work safety be ensured and avoid yi
