Since China joined the WTO in 2000, with the improvement of national living standards, consumers' spending habits and preferences have changed significantly, leading to higher demands for food quality. Vacuum-packaged food has become increasingly popular among consumers. To adapt to these social developments, the food industry has been continuously upgrading its equipment. In recent years, the fully automatic vacuum pouch packing machine has been developed and produced. This machine not only reduces labor costs but also improves factory production capacity. So, what exactly is an automatic vacuum pouch packing machine, and how does it work?
1. Working Principle of the Automatic Vacuum Pouch Packing Machine
The automatic vacuum packaging machine consists of a bag filling rotary system and a vacuum sealing rotary system. The vacuum sealing system rotates continuously at a constant speed. The operation is simple and convenient, and bag changes are quick and easy. Once the task requirements are entered, the weighing, packaging, and other operations are carried out automatically without the need for manual intervention. The equipment is equipped with a detection system: if the packaging conditions are not met (e.g., no bag or abnormal condition), it will not feed materials or seal. The sealing process uses instantaneous heating and rapid cooling, resulting in flat and aesthetically pleasing seals.
2. Operating Instructions for the Automatic Vacuum Pouch Packing Machine
Bag Loading: The machine picks up and delivers bags to the mechanical gripper. It provides a warning if no bag is detected, reducing labor intensity.
Printing Production Date: Equipped with ribbon detection. If the ribbon runs out, an alarm and on-screen notification are triggered, ensuring proper coding on the packaging bags.
Bag Opening: The machine detects whether the bag is opened correctly. Material will not be dropped if the bag fails to open, preventing waste.
Filling Materials: If no material is detected, neither filling nor heat sealing will occur, ensuring that no bags are wasted.
Heat Sealing: If there is an abnormal temperature, a warning is triggered to ensure sealing quality.
Cooling & Discharging: Ensures the seals are aesthetically pleasing.
3. Application Range of the Automatic Vacuum Pouch Packing Machine
This machine is widely used with various packaging materials, including paper-plastic laminate, plastic-plastic laminate, aluminum-plastic laminate, PE composites, and more. By using different metering devices, it can achieve fully automatic vacuum packaging for different product types, such as granules, powders, blocks, liquids, soft (retort pouches), toys, hardware products, and more.
The above information about the automatic vacuum pouch packing machine may seem detailed, but it plays a critical role for factory technical personnel. Although the machine involves multiple operating steps, food manufacturers do not need to worry about operating complexity. When designing the equipment, food industry manufacturers aim to reduce labor and improve digital and mechanical management. Apart from manual bag loading at the start of operation, no other steps require manual intervention – achieving truly unmanned operation.
