The market of blow molding machines has a bright future, and users should pay attention when using and maintaining

In recent years, with the rapid development of the domestic plastic bottle market, the plastic blow molding machine industry has ushered in an opportunity for development. The blow molding machine is mainly a fully automatic stretch blow molding equipment. In other words, it is a machine for blowing bottles, which in layman's terms means a machine that can blow plastic particles (softened into liquid) or finished preforms into bottles through a certain production process. The bottle is made by a blow molding machine, so that the subsequent materials can be poured into the bottle, which saves time and effort and has high blowing efficiency. Some people in the industry pointed out that at present, my country's packaging machinery has become one of the industries with very rapid development in the traditional machinery manufacturing industry, and the annual demand is increasing. Due to the good development prospects of the plastics processing industry, it will still provide a steady stream of power for the rapid development of my country's blow molding machine industry. At present, the food, beverage, pharmaceutical and other industries have a large demand for blowing machinery. On the one hand, due to the relatively low price of plastic packaging materials, the production is simple and convenient, especially the food and beverage packaging is widely used. On the other hand, in the face of the ever-changing market changes, the production of plastic packaging materials is simple and convenient, and food packaging enterprises can respond flexibly to the shorter and shorter life cycle of packaging materials. For this reason, bottle blowing machinery is still popular in the market. According to the author's understanding, there are many kinds of blowing equipment on the market, including automatic blowing machines, semi-automatic blowing machines and other highly automated blowing machines, which can meet the technological needs of different users, and greatly improve blowing. efficiency. So, how does the user operate the blow molding machine correctly, and what needs to be paid attention to in maintenance? The technicians introduced that, first, the preform needs to be correctly placed in the preform container, and then automatically enters the preform positioning device through the conveying system. Secondly, the preform mouth should be upward to avoid the appearance of the inverted model, which will affect the quality of the bottle and cause unnecessary waste of plastic packaging materials. Immediately afterwards, the preforms are automatically loaded onto the preform fixing equipment to avoid loosening of the preforms during transportation, and then sent to the drying tunnel. In addition, after the preform is heated, it is transported to the blowing and drawing system. Then, place the preheated preform (preform) into the prepared blow mold (clamping), and then blow and draw the preform (preform) into the desired shape through low-pressure blowing, high-pressure blowing, and exhausting. bottle. Finally, the mold is opened, and after the bottle is formed, the bottle is transported from the bottle blowing platform by the automatic demoulding system device. It is worth mentioning that if the automatic blow molding machine can be operated automatically, the process of manually placing the preheated preforms (preforms) into the blow mold in the middle is eliminated, and the blowing efficiency is significantly improved. Of course, in order for the blowing machine to work normally and achieve the purpose of bottle forming, users not only need to understand and master the normal operation, but also need to maintain the blowing machine, which can not only avoid blowing during the production process to a certain extent. Machine failure, prevent economic losses caused by downtime, and also help to extend the service life of the blow molding machine. Generally speaking, if there is no feeding at the feeding position, it is necessary to quickly feed or check whether the control contactor of the hoist is energized. If there is an old feeding tray, check the length of the preform (preform). Because the length of the preform (preform) is long, it cannot be properly placed in the preform container, and the phenomenon of jamming will occur. If the bottle is blown, it cannot be removed from the mold. At this time, the user can open the mold and manually open and close the mold. Or check the exhaust time setting. If the exhaust setting is normal, and there is a fault every time the bottle is blown, it may be the problem of the exhaust valve, please open the exhaust valve to check the spring and seal condition.
