[0002] Flour filling and packaging machine is a kind of equipment used for automatic filling and packaging of flour, usually used in industrial production lines. This machine can efficiently put flour into packaging bags, weigh and seal them as needed.

[0003] The flour is stored in a feeding system, which can be a large storage silo or a conveyor system; the filling machine usually includes a weighing system to accurately measure the weight of the flour. Once the weight of the flour reaches the set value, the filling machine will fill the flour into the pre-opened bag. The filling process usually uses a feeder or a rotary filler to quickly and accurately load the flour into the bag. After filling, the bag will be sealed, usually by heat sealing or pressure sealing to ensure the bag is sealed.

[0004] The packaging bags of existing packaging machines are generally fixed to the outside of the flour discharge port by a fixing device, but there is a large height difference between the bottom of the packaging bag and the discharge port, which causes a lot of dust to be generated during the flour bagging process, polluting the environment, causing harm to the body when inhaled by the human body, and also causing waste of flour.
