Automatic checkweigher for every step from packing to precise screening

On the busy logistics line, every express parcel carries the expectations of customers and the responsibilities of merchants. After these parcels are carefully packed by the packing machine and tightly sealed by the sealing machine, they embark on a new journey - the automatic checkweigher. Here, it is a key stop to ensure that the weight of the parcel is accurate.

**Step 1: Accelerate the journey and ensure independence**

The express parcels first enter the "acceleration section" of the checkweigher, which seems to be their small runway. Here, the distance between the parcels is cleverly opened to ensure that each parcel can enter the next "weighing section" in the best condition. Even those parcels with slightly messy arrangements can become orderly under the guidance of the acceleration section and prepare for accurate weighing.

**Step 2: Accurate weighing, strict quality control**

As the parcel slowly enters the "weighing section", a silent weight contest quietly takes place. The high-precision weighing system captures the weight information of the parcel at lightning speed and quickly makes a judgment: Is the weight of this parcel up to standard? If the package meets the preset target weight range, it will be released smoothly and continue its logistics journey; if the weight is found to be inconsistent, the system will immediately send out a rejection signal and record the unqualified "score".

**Step 3: Accurate rejection to ensure quality**

The package that receives the rejection signal will then face the rigorous test of the "rejection section". Here, the robotic arm or conveyor belt performs the rejection action with amazing accuracy, accurately sending those unqualified packages to the unqualified product area, ensuring that only qualified packages can continue to move forward.

**Step 4: Intelligent monitoring to prevent congestion**

After the package passes the rejection section smoothly, it does not mean that their journey ends. The photoelectric sensing area is like a keen sentinel, always monitoring the smoothness of the conveyor line. Once signs of congestion are found on the conveyor line, the photoelectric feedback system will take immediate action and send a command to the packing machine to pause or delay the packing, effectively avoiding the occurrence of logistics bottlenecks.

Every step of the automatic checkweigher is a double guarantee for the quality of the package and the efficiency of logistics. Here, the power of science and technology is fully utilized, providing solid support for the smooth operation of modern logistics.
