Checkweigher completes the measurement of the weight of the product during the conveying process, and compares the measured weight with the pre-set range, and the controller sends out the instruction to reject the products with unqualified weight, or distribute the products with different weight ranges to the designated area. Online sorting scale consists of weighing conveyor, controller and inlet/outlet conveyor. The weighing conveyor collects the weight signals and sends them to the controller for processing. The in-feed conveyor ensures adequate spacing between products by increasing the speed. The outfeed conveyor is used to transport the inspected products away from the weighing area.

The working process of the checkweigher is as follows: weighing prepares the product to enter the infeed conveyor, the speed setting of the infeed conveyor is generally determined jointly with the spacing of the products and the required speed. The purpose is to ensure that only one product can be on the weighing platform during the checkweigher's working process. WEIGHING PROCESS When the product enters the weighing conveyor, the Weighing system recognizes that the product to be inspected has entered the weighing zone according to external signals, such as photoelectric switch signals, or internal level signals. Depending on the speed of the weighing conveyor and the length of the conveyor, or on the level signal, the system can determine the time at which the product leaves the weighing conveyor. From the time the product enters the weighing platform to the time it leaves the platform, the weighing module will detect the weight signal, and the weighing instrument will select the signal in the stable agricultural area for processing, and then the weight of the product will be obtained. Sorting processWhen the controller gets the weight signal of the product, the system will compare it with the pre-set weight range and sort the product, the sorting type will be different according to the application.
