Bottle blowing machine: It is a machine that blows bottles. A very simple explanation is a machine that can blow plastic particles (soften into liquid) or finished preforms into bottles through certain technological means. 1. Features of automatic blow molding
machine Plastic hollow containers are widely used in beverage, medicine, cosmetics, food and chemical industries because of their light weight, low price and high safety. More manufacturers choose plastic containers to Instead of the conventional glass container. Today's very advanced equipment, molds and raw materials in the plastics industry are all displayed in front of us, new technologies and new applications emerge one after another, and the field of plastic hollow molding is also fruitful. With the soaring global oil price, the price of plastic raw materials remains high, and the development of alternative products with low energy consumption and low raw material consumption is also one of the market trends. 1. The oil-free airbag clamping technology is adopted, the clamping force is large, and the operating force of the toggle joint is small and the service life is long. 2. The patented technology of flying out seal is adopted to make the sealing, especially the sealing of jars easier. 3. Adopt Keyence PLC, touch screen, easier operation and high reliability. 2. Operation steps of the automatic blow molding 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 from the mouth up to the preform holder, and then send it into the drying tunnel. Step 3: After heating, the preform is sent to the blowing and drawing platform, and then the mold is locked, followed by low-pressure blowing and drawing, high-pressure blowing and drawing, exhaust, and finally mold opening. Step 4: The finished bottle is taken off the bottle blowing platform by the automatic demolding system. 3. Technical development of automatic bottle blowing machine
Beverage enterprises have two urgent needs for blowing equipment. One is that due to the continuous rise in the price of plastic raw materials, beverage enterprises are always thinking about how to reduce packaging costs to maximize profits. Therefore, it is necessary to The use of advanced blow molding equipment to produce lighter weight bottles; the second is that due to the rapid changes in the market, beverage manufacturers must respond flexibly to the shorter and shorter life cycle of beverages, corresponding to the production of PET bottles Due to the increasingly frequent product update problems in the production process, the time for changing the molds needs to be reduced to a very low level during the production process. These two urgent needs have created a big problem for bottle blowing equipment suppliers. The closed-loop technology refers to the integration of the process parameters of the 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. The intelligent machine control technology aims to improve the quality assurance system of the blow molding machine. Various data of the preform such as bottle wall thickness can be monitored through the use of the AgrPETWallplus monitoring system. During operation, the data that deviates from the rated value of the system will be identified immediately, and this information will be transmitted to the control system of the preform heating unit of the blow molding machine in time. The control system will quickly reflect and individually control the heating lamps in the heating furnace. rated value. Therefore, even if the data of each bottle is different, the quality of the produced bottle is still stable and reliable under the condition that the initially set process parameters remain unchanged.
