Introduction of Automatic Blow Molding Machine Equipment

Automatic blow molding machine: It is a bottle blowing machine. The most simple explanation is a machine that can blow plastic particles (softened into liquid) or preforms into bottles through certain technological means.

First, the characteristics of the automatic blow molding machine

Plastic hollow containers are widely used in beverage, medicine, cosmetics, food and chemical industries due to their light weight, low price, and high safety. They have attracted more manufacturers to choose plastic containers instead of glass containers. Today, the most advanced equipment, molds and raw materials in the plastics industry are presented to us one by one, new technologies and new applications are emerging one after another, and the field of plastic hollow molding is also fruitful. With the soaring world oil prices, the price of plastic raw materials is also high, and the development of alternative products with low energy consumption and low raw materials is also one of the market trends.

1. Using oil-free airbag mold clamping technology, the clamping force is large, and the toggle operation is less forceful and has a long life.

2. Adopting the patented flying-out sealing technology to make sealing easier, especially for jars.

3. Using KEYENCE PLC, touch screen, easy operation and high reliability.

Second, the operation steps of the automatic bottle blowing machine

Step 1: Place the preform in the preform container and automatically enter the preform positioning device through the conveying device.

Step 2: Automatically load the preform with the preform mouth upwards onto the preform holder, and then send it into the drying tunnel.

Step 3: After heating, the preform is sent to the blowing platform, and then the mold is locked, followed by low pressure blowing, high pressure blowing, exhaust, and finally mold opening.

Step 4: The finished bottle is taken off the bottle blowing platform by the automatic demoulding system.

3. Technical development of automatic bottle blowing machine

Beverage companies have two urgent needs for bottle blowing equipment. One is that due to the continuous increase in the price of plastic raw materials, beverage companies are always thinking about how to reduce packaging costs to maximize profits. Therefore, they need to use advanced blowing equipment to produce lighter weight. The second is that due to the rapid changes in the market, beverage manufacturers must respond flexibly to the shorter and shorter life cycles of beverages. Corresponding to this is the increasingly frequent product update problem in the production of PET bottles. It is necessary to minimize the time to replace the mold. These two urgent needs have created a big problem for the bottle blowing equipment supplier.

Closed-loop technology refers to the integration of the process parameters for online verification into the process control system of the stretch blow molding machine to form a closed production cycle process that combines automatic control and automatic adjustment. Intelligent machine control technology aims to improve the quality assurance system of the bottle blowing machine. Through the use of the AgrPETWallplus monitoring system, various data such as bottle wall thickness and other preforms can be monitored. When working, the data deviating from the rated value of the system will be recognized immediately, and this information will be transmitted to the control system of the preform heating unit of the blow molding machine in time, and the control system will quickly reflect and individually control the heating lamps in the heating furnace The rating. Therefore, even if the data of each bottle is different, the quality of the bottle produced is still stable and reliable under the condition that the initially set process parameters remain unchanged.
