The five gallon semi-automatic bottle blowing machine places the preform in the preform container and automatically enters the preform positioning device through the conveying device. Automatically load the preform onto the preform holder with its mouth facing upwards, and then send it into the drying oven. After heating, the bottle embryo is sent to the blowing and pulling platform, and then locked in the mold. It undergoes low-pressure blowing and pulling, high-pressure blowing and pulling, exhaust, and finally the mold is opened. The finished bottle is removed from the blowing platform by an automatic demolding system. Beverage companies have two urgent needs for bottle blowing equipment due to technological development. One is that as plastic raw material prices continue to rise, beverage companies are constantly thinking about how to reduce packaging costs to maximize profits. Therefore, they need to use advanced bottle blowing equipment to produce lighter bottles; The second reason is that due to the rapid changes in the market, beverage production enterprises must respond flexibly to the increasingly short lifecycle of beverages. Correspondingly, there is a growing issue of product updates in PET bottle production, which requires minimizing the time for mold replacement during the production process. These two urgent demands have posed a significant challenge for bottle blowing equipment suppliers.
