Weighing and checking machine is composed of load cell and conveyor and rejection device, combined with microprocessing technology can count the number of products, conveying flow, etc., intelligent artificial display interface of modern intelligent equipment. Mainly used for automated packaging assembly line through the product on-line dynamic weighing automation equipment, can detect the weight of the continuous process of unqualified products, and can be automatically categorized and statistics on the product.

With high speed dynamic weight reading to check the weight of the products on the production line, it can detect the products with unqualified weight in the continuous production line, and accordingly execute the up and down line judgment or the control of automatic weight sorting, especially suitable for checking the missing pieces in the packaging products. Packaged products are weighed and detected by the checkweigher, qualified products are sent back to the original conveyor belt, and unqualified products are rejected (or alarmed and stopped), and it has the functions of classifying and counting products according to the settings.

The goods are put into the weighing conveyor belt of the front section of the automatic sorting scale, and transported to the weighing platform of the equipment for weighing. After the goods enter the weighing section one after another, the control system quickly recognizes that the goods have entered the weighing belt according to the photoelectric signal. Depending on the speed of the weighing section and the length of the conveyor, the control system can determine when the product has left the weighing section. From the time the product enters the weighing platform to the time it leaves the weighing platform, the weighing module will detect the signal, and the controller will select the signal from the signal stabilization area for processing to obtain the weight of the product.

It adopts continuous dynamic automatic weighing method to detect the weight of the products, equipped with automatic rejecting mechanism, thus realizing high-speed and high-precision weight detection and sorting on the assembly line. It is suitable for loading shortage inspection of finished products in small packaging industry. Unique design of mechanical structure and operation interface, very convenient for users to operate and data management statistics. When in use, the operator only needs to simply set the upper and lower limits of the inspected articles' over-difference values and then press the [Start] button, the system will enter into the full-automatic working state, the qualified products will pass through and the unqualified products will be rejected automatically. At the same time in the human-machine interface comprehensively display the quantity, speed, weight, product information and other information. The machine is used for package inspection, thus realizing the full inspection of products out of the factory, and also achieving the effect of saving labor.
