The outer packaging of beverages is a great tool for attracting consumers. Throughout the relevant packaging on the market today, the materials can be varied, such as paper, metal cans, plastic bottles, etc. However, the beverage box has seam marks. Metal cans also have gaps to follow, plastic bottles are basically one-piece molding, are you as curious as the author, the color is diverse, and the plastic bottle of plastic material is made of what kind of equipment?
In the production process of plastic beverage bottles, the blowing machine can be called the number one. Just like the information transmitted by the name, the plastic bottle is blown out. The raw material is softened into liquid or made into plastic preforms. These raw materials have become familiar plastic bottles after being blown by the blow molding machine. At present, the blowing methods of blow molding machines are hollow extrusion and one-step blowing and two-step blowing. The blow molding machine needs to first illuminate the preform through an infrared high-temperature lamp, so that it can be softened to a suitable degree and then start the blowing process.
Blowing machine adapts to different sizes of bottles according to the size of the cavity. The volume of the bottle is between 0.25L-10L. The larger the blown bottle, the lower the production efficiency. Take the company's products, the company The small cavity series blow molding machine (suitable for 0.75L or less) can reach 81000 bottles/hour, while the large cavity series blower has a maximum capacity of 14,000 bottles/hour.
Nowadays, the competition in the food and beverage market is becoming more and more fierce. More and more food companies are paying attention to the improved production of packaging. They hope to attract consumers' attention through a variety of bottles, which will drive their desire for consumption. There are more and more shaped bottles on the market. The blow molding machine adapts to the special-shaped bottles mainly relying on the replacement of the bottom mold and the mold. The blow molding equipment manufacturers have considered this problem in the initial design of the equipment, using the easy-to-remove, assembled functional parts. A person can complete a mold change in just two or three minutes.
In the beverage industry, carbonated beverages are a special type of beverage products. When the gas filled in the bottle undergoes collision and temperature rise, the state changes, so the requirements for the bottle are higher. Most of the blow molding machines on the market today. It can adapt to the high requirements of carbonated beverages for bottles. The products can adapt to the production of ordinary water bottles as well as CSD bottles specially designed for carbonated beverage equipment. At present, the same equipment will have a lower production capacity when producing CSD bottles. Enterprises need to ask clearly when purchasing products.
Beverages and foods are a waste of resources in the production process. Nowadays, with the increasing slogan of environmental protection and energy conservation, how to solve problems for related companies has become a major focus of blow molding equipment. Although the blow molding machine does not involve water resources utilization, In the production process, it is necessary to heat the mold, and it is also necessary to use gas resources such as high pressure gas and low pressure gas. It is reported that some enterprises have changed the original pneumatic stretching of the blowing machine to servo stretching, and the pneumatic sealing to mechanical sealing, saving Low-pressure gas; three-time blowing, two new recycling processes to save high-pressure gas consumption of about half.
As a kind of equipment in the packaging process, the bottle blowing machine needs to cooperate with the bottle washing machine, filling production line and other equipment in the actual production process, which is bound to face the cooperation problem between the equipment. For many enterprises, their equipment is not the same. A company produces a blow molding machine that works in conjunction with other company equipment. Many blow molding machines can independently complete the blowing process by improving their own equipment processes, or they can be connected to the filling line, and can also be placed in the blowing and swirling Work in the all-in-one machine.
The author refers to the well-known foreign blow molding equipment manufacturers, and found that their maximum capacity of small bottle blowing equipment can reach 82,000 bottles / hour, the corresponding equipment in China is almost the same. But the production capacity of carbonated beverage bottles, large and medium bottle blowing machines and other equipment is relatively high. Large gap. Under this circumstance, China's related blow molding equipment manufacturers still need to recognize their limitations, increase equipment R & D investment, and achieve the catch-up of blowing equipment as soon as possible.
