The Principle of Quantitative Packaging Scale

When the quantitative packaging scale enters the automatic operation state, the weighing control system opens the feeding door to start feeding, the feeding device is fast and slow feeding mode.When the material weight reaches the fast feeding set value, stop fast feeding and keep slow feeding. When the material weight reaches the final set value, close the feeding door to complete the dynamic weighing process, at this time, the system detects whether the bag clamping device is in the predetermined state, when the bag has been clamped, the system sends a control signal to open the weighing hopper discharge door, the material enters the bag. After the bag is clamped, the system will send a control signal to open the unloading door of the weighing hopper, the material will enter the bag, and the unloading door of the weighing hopper will be closed automatically when the material is finished. After the bag is dropped, the bag is sewn and transported to the next station. This cycle runs automatically.
