The operating principle of vacuum premade bag packaging machine

The operating principle of the vacuum premade bag packaging machine is mainly based on a series of automated and mechanized steps to ensure efficient and accurate completion of the packaging process. The following is a detailed explanation of its operating principle:

1.Bag supply and positioning: Firstly, the vacuum premade bag packaging machine automatically feeds the prefabricated packaging bags into the machine through the bag feeder. These bags are accurately positioned and fixed in the working area of the machine through mechanical or pneumatic devices.

2.Opening and preparation: Once the bag is positioned, the machine will perform the opening operation. This usually involves opening the bag for subsequent material filling and vacuum treatment. Some advanced vacuum premade bag packaging machine also have detection functions to ensure that the bags are opened correctly without any damage or errors.

3.Material filling: Next, the machine accurately places the material to be packaged into the opened bag. This can be achieved in different ways, such as controlling the amount of material through measuring devices or using automatic feeding systems.

4.Vacuum treatment: After the material is filled, the vacuum feeder starts the vacuum pump and extracts the air inside the bag through the vacuum chamber. This process helps to remove excess air from the bag and tightly compress the material, making the packaging more compact.

5.Sealing and Completion: Finally, the machine closes the opening of the bag through heat sealing or other sealing methods, completing the entire packaging process. The sealing operation should ensure that the bag is tightly sealed to prevent material leakage or external contamination.
