The concept, classification and function of packaging machinery

1. The concept of packaging machinery

The definition of packaging machinery in the national standard GB/T4122.2-1996 "Packaging Terminology Machinery" is: "Machines that complete all or part of the packaging process. The packaging process includes major packaging processes such as forming, filling, and wrapping, as well as related The front and rear processes, as well as the front and rear packaging processes such as cleaning, drying, sterilization, labeling, bundling, assembly and disassembly, and other auxiliary processes such as transfer and sorting.”

2. Classification of packaging machinery

1. Classification according to the degree of automation of packaging machinery

(1) Fully automatic packaging machine. The fully automatic packaging machine automatically supplies packaging materials and contents, and can automatically complete other tasks.

Machines for the packaging process.

(2) Semi-automatic packaging machine. A semi-automatic packaging machine is a machine that manually supplies packaging materials and contents, but can automatically complete other packaging processes.

2. Classify according to the type of packaging products.

(1) Special packaging machine. Special packaging machine is a machine specially used for packaging a certain product. (2) Multi-purpose packaging machine. A multi-purpose packaging machine is a machine that can package two or more products by adjusting or replacing relevant working parts.

(3) Use packaging machine. Diyong packaging machine is a machine suitable for packaging two or more different types of products within a specified range.

3. Classification according to the function of packaging machinery. Packaging machinery can be divided according to different functions: filling machinery, filling machinery, wrapping machinery, sealing machinery, labeling machinery, cleaning machinery, drying machinery, sterilization machinery, strapping machinery, container machinery, multi-functional packaging machinery, packaging materials Manufacturing machinery, packaging container manufacturing machinery, and auxiliary packaging machinery for completing other packaging operations.

4. Packaging production line. A production line composed of several packaging machines and other auxiliary equipment that can complete a series of packaging operations is a packaging production line.

3. The role of packaging machinery

Modern industrial production mainly includes three basic links, namely raw material processing, intermediate processing and packaging. Packaging is a very important link in industrial production. Packaging machinery is the fundamental guarantee for realizing packaging mechanization and automation. Therefore, packaging machinery plays an important role in modern industrial production.

(1) Packaging machinery has realized the specialization of packaging production and greatly improved production efficiency. For example, the productivity of a beer filling machine can be as high as 40,000 bottles/hour, which is unmatched by manual filling.

(2) Packaging mechanization reduces labor intensity, improves working conditions, protects the environment, saves raw materials, and reduces product costs. For example, when liquid products are packaged manually, it is easy to cause product splashing; when powdery products are packaged, dust is often caused to fly, which not only pollutes the environment, but also wastes raw materials. The use of mechanical packaging can prevent products from being lost, which not only protects the environment, but also saves raw materials.

(3) Ensure the hygiene and safety of packaged products, improve product packaging quality, and enhance market sales competitiveness. For example, the hygiene and safety requirements of medicines are very strict, and the use of mechanized packaging avoids direct contact between human hands and medicines, reducing contamination of medicines. At the same time, due to the high speed of mechanized packaging, the residence time of drugs in the air is short, which also reduces the chance of contamination and is conducive to the hygiene and safety of drugs.

(4) Extend the shelf life of products and facilitate product circulation. The use of vacuum, ventilation, sterile and other packaging machines can make the circulation range of products wider and extend the shelf life of products.

(5) The product uses a packaging machine, which can reduce the packaging site area and save infrastructure investment. When products are packaged manually, there are many packaging workers and the process is not compact, so the packaging operation occupies a large area and requires a lot of investment in infrastructure. However, when mechanical packaging is used, the supply of items and packaging materials is relatively concentrated, and the arrangement of each packaging process is relatively compact, reducing the number of The packaging area can save infrastructure investment.
