Typically mounted on the bottom or side of the platform, the load cell generates an electrical signal by contact with the item or by sensing changes in its weight. Different types of load cells have varying accuracy, ranges, and applicable environments; the appropriate load cell should be selected based on actual needs. The conveyor mechanism, consisting of a drive motor, conveyor belt, rollers, and chains, is responsible for conveying items. The drive motor provides power, enabling the conveyor mechanism to operate at a specific speed. The conveyor belt, rollers, or chain is selected based on the item's shape, weight, and conveying requirements to ensure smooth conveyance. The control system controls the operation of the weighing and rechecking conveyor platform, including signal acquisition from the load cell, speed regulation of the conveyor mechanism, and triggering of alarms. The control system can be based on a PLC, microcontroller, or industrial computer, offering high stability and reliability. Operation can be via a touchscreen, buttons, or remote control, making parameter settings and control more convenient.
