After being fed from the previous production line or by manual loading, the product is conveyed into the "metal detection and weighing section".
1. The product enters the "detection section" of the metal detector: defective products with metal foreign objects are automatically alarmed; the product then enters the "acceleration section" of the checkweigher, where the distance between products is stretched to ensure that single products rather than multiple products enter the "weighing section"; when product sequencing is irregular, it can also be arranged by the "acceleration section".
2. The product enters the "weighing section" of the checkweigher: the weighing system quickly detects the product weight and immediately judges whether the weight is within the target weight range. If the weight is qualified, the product is accurately conveyed out of the checkweigher; if not, a rejection delay signal is given. At the same time, the system automatically records the number of qualified and unqualified products.
3. The product enters the "reject section" of the checkweigher: when the reject section detects the rejection delay signal, it performs the rejection action at the appropriate time, accurately removing unqualified products.
