Packaging is a general term for the process of measuring out, wrapping, and packaging products. It protects products and makes them easy to transport, store, and sell. Food packaging must be both practical and decorative to enhance the appearance of products, promote them, and attract consumers.
Type of Packaging Equipment
There are many types of packaging: depending on the sales objectives of different products, they can be categorized into industrial packaging, commodity packaging, and military packaging; depending on their functions, they can be categorized into inner packaging (including primary packaging and intermediate packaging) and outer packaging; depending on the nature of the product, they can be classified into block packaging, granular packaging, powder packaging, liquid packaging, sauce packaging, etc.; depending on the specific requirements of the product, they can be subdivided into food packaging, moisture-resistant packaging, fragile packaging, and packaging for hazardous materials. Packaging materials must be non-toxic and comply with the requirements of the national health inspection. There must also be a requirement for easy access, and the packaging must be able to resolve the conflict between sealing and easy access.
Inner packaging is the most basic form of packaging, which includes primary packaging and secondary packaging. Primary packaging is a form of packaging in which the packaged item and the packaging material come into direct contact. Examples include candy wrappers, beverage bottles, detergent bags, toothpaste tubes, etc. Secondary packaging involves repackaging the primary-packaged products according to a specific quantity or pattern, such as packaging items in bottles or bags and then in cardboard boxes, or combined packaging of cosmetic sets.
Outer packaging Collecting a certain number of individually packaged products and repackaging them for ease of transport and storage. The outer packaging is usually placed in cardboard or wooden boxes secured with flat plastic or metal straps. Moisture-resistant items must be lined with plastic film, and shock-resistant items must be protected with foam plastic. The specifications, dimensions, and markings of the outer packaging must comply with the relevant national standards.
The Main Methods of Food Packaging Options such as bottling, canning, packaging, bundling, etc., can be selected based on the nature of the product, storage and usage requirements, regional sales practices, and consumer psychology. The same product can be packaged in various ways, such as hardcover, simple packaging, bulk packaging, large packaging, small packaging, family-size packaging, or bottling, packaging, canning, and bundling. This is done to meet the needs of different sales channels and different consumer segments.
Composition of Packaging Equipment
The structure of the packaging machine consists of three parts: the drive unit, the transmission unit, and the output unit.
To facilitate the analysis and understanding of the operating principle and structural characteristics of the packaging machine, we further break down the three main components of the packaging machine into 8 aspects based on their functions. We refer to these as the 8 elements of the packaging machine.
Quantitative Feeder: Sort, measure, arrange, and transport the items to the designated station.
Sorting and Feeding Machine: Cut, sort, and arrange packaging materials or containers by quantity, and transport them to the designated station.
Main Conveyor System: A device that transports packaging items and materials in sequence from one station to the next. This device can be omitted in single-station packaging machines.
Packaging Application Device: A machine that performs packaging operations directly, such as packing, filling, sealing, labeling, and bundling.
Device for discharging the finished product: This is a device that retrieves the packaged finished product from the packaging output device and removes it from the packaging machine.
Power machine and transmission deviceThe power source is typically an electric motor. The transmission mechanism includes a reduction gear, a mechanism for transmitting and converting power and motion, and can take various forms, such as mechanical, hydraulic, pneumatic, electromagnetic, and optical.
Control Unit: It includes the display and control unit for packaging speed, pressure, temperature, and cycle time; the monitoring and control unit for packaging quantity and quality; and various automatic safety devices for the machine.
Machine BodyIt is used to support and secure the relevant components so that they maintain their operating position and fulfill a specific protective function for the machine. The design must be easy to operate and maintain, and its appearance should be as attractive as possible.
The figure is a block diagram of the packaging machine, illustrating the relationship between the 8 components of the packaging machine. The double-line arrows in the diagram represent the main conveyor system for the packaging materials and the packaging materials themselves; the solid-line arrows represent the transmission relationship; and the dotted-line arrows represent the control relationship.
Conclusion
Packaging equipment is an important part of light industrial manufacturing. It is widely used in the production of food, daily necessities, cosmetics, medicines, textiles, office supplies, toys, household appliances, and small hardware products, and is also used in the final stage of production. Poor packaging quality has serious consequences for product quality and economic benefits.
Modern packaging equipment is changing by the day. It is evolving rapidly in terms of packaging speed, quality, types of packaging, and the mechanization and automation of the packaging process. Research and development of new packaging processes, the emergence of new production and packaging materials, and the invention and use of new technologies have made it possible to design and manufacture modern, innovative, efficient, fast, and high-quality packaging machines.
