The automatic checkweigher is mainly completed by three parts: buffer part, dynamic weighing part and weight sorting part. Buffer section: mainly used for placing products, the speed is a little slower than the last two sections, mainly used as a buffer, so that the products enter the dynamic weighing section at a constant speed. Dynamic weighing: the products are dynamically weighed during the movement of the belt, and the weighing data is fed back to the control system. Weight Sorting Section: According to the weight data fed back from the dynamic weighing section, it determines the sorting action at which level of exit, and executes the rejecting action after the products run to the corresponding rejecting port.

Weighing conveyor will pass through the material on the belt, through the weighing scale frame under the load cell to detect the weight, the feeding controller will be the flow and set the flow rate for comparison, the output signal from the controller to control the frequency converter speed regulation, to achieve the requirements of quantitative feeding. It is an automatic scale that continuously weighs the bulk material on the conveyor belt without the need to subdivide the mass or interrupt the movement of the conveyor belt.
