Packaging is a general term for the process of quantitative loading, wrapping, and packaging of products. It protects products and makes them easy to transport, store, and sell. Food packaging should be both practical and decorative to beautify and promote products and attract consumers.

Type of Packaging Equipment

There are many types of packaging: according to the sales targets of different products, it can be divided into industrial packaging, commodity packaging, and military packaging; according to the packaging functions, it can be divided into inner packaging (including direct packaging and intermediate packaging) and outer packaging; according to the nature of the product, it can be divided into block packaging, granule packaging, powder packaging, liquid packaging, sauce packaging, etc.; according to the special requirements of the product, it can be divided into food packaging, moisture-proof packaging, fragile packaging, and dangerous goods packaging. Packaging materials should be non-toxic and meet national health inspection requirements. There should also be a requirement for easy access, and the packaging should be able to solve the contradiction between sealing and easy access.

Inner packaging is the most basic form of packaging, including direct packaging and intermediate packaging. Direct packaging is a form of packaging in which the packaged object and the packaging material are in direct contact. Such as candy paper packaging, beverage bottle packaging, laundry detergent bag packaging, toothpaste hose packaging, etc. Intermediate packaging is to package the directly packaged products again according to a certain quantity or pattern, such as packaging in bottles or bags and then in cartons, or combined packaging of cosmetic series.
Outer packaging is to collect a certain number of products that have been packaged internally and repackage them for the convenience of transportation and storage. Outer packaging is mostly packed in cardboard or wooden boxes, with plastic or iron flat straps. Moisture-proof items should be lined with plastic film, and shock-proof items should be cushioned with foam plastic. The specifications, dimensions and markings of the outer packaging should comply with relevant national standards.
The main food packaging methods include bottling, canning, boxing, bagging, boxing, wrapping, bundling, etc., which can be selected according to the nature of the product, storage and use requirements, regional sales habits and customer psychology. The same product can have a variety of different packaging methods, such as hardcover, simple packaging, bulk; large packaging, small packaging, family packaging; or bottling, boxing, canning, and bagging. To meet the needs of different sales objects and different consumer levels.

Composition of Packaging Equipment

The packaging machinery structure is composed of three parts: power part, transmission part and execution part.
In order to facilitate the analysis and understanding of the working principle and structural characteristics of the packaging machine, we further decompose the three major components of the packaging machine into 8 aspects according to their working functions, and call them the 8 elements of the packaging machine.

Quantitative feeding device： Sort, measure, arrange and transport the items to the predetermined station.
Sorting and feeding device：Quantitatively cut or sort and arrange the packaging materials or containers and transport them to the predetermined station.
Main conveying device： A device that transports the packaging items and materials from one station to the next station in sequence. This device can be omitted for single-station packaging machines.
Packaging execution device： A device that directly performs packaging operations such as wrapping, filling, sealing, labeling, and bundling.
Finished product output device：This is a device that unloads the packaged finished product from the packaging execution device and sends it away from the packaging machine.
Power machine and transmission device： The power machine is generally an electric motor. The transmission device includes a reducer, a transmission and conversion mechanism for power and motion, and can be in various forms such as mechanical, hydraulic, pneumatic, electromagnetic, and optical.
Control device： It includes the indication and control device for packaging speed, pressure, temperature, and action time, the monitoring and control device for packaging quantity and quality, and various automatic protection devices for the machine.
Machine body：It is used to support and fix the relevant parts to maintain their specified working positions and play a certain protective role for the machine. Its structure should be easy to operate and maintain, and its appearance should be as beautiful as possible.
The figure is a block diagram of the packaging machine, which shows the relationship between the 8 elements of the packaging machine. The double-line arrows in the figure represent the main conveying system of the packaging materials and packaging materials, the single solid line arrows represent the transmission relationship, and the dotted line arrows represent the control relationship.

Packaging equipments is an important equipment in light industrial production. It is widely used in the production industries of food, daily necessities, cosmetics, medicines, textiles, stationery, toys, household appliances and small hardware products, and is used in the last process. Poor packaging quality will have a serious impact on product quality and economic benefits.
Modern packaging equipment is changing with each passing day. It is developing rapidly in terms of packaging speed, quality, types and mechanization and automation of the packaging process. The research and development of new packaging processes, the emergence of new manufacturing materials and packaging materials, and the invention and use of new technologies have made the design and manufacture of modern new, efficient, high-speed and high-quality packaging machinery possible.
