Weighing and Inspection Machine
A weighing and inspection machine is an online checkweighing device that can be integrated with various packaging production line conveyors. It is mainly used for online monitoring of product weight to determine if any parts or products are missing from the packaging. Online checkweighing completes the product inspection during the product conveying process, comparing the measured weight with a pre-set weight value. The control system calculates and issues instructions to reject unqualified products.
Maotong Series Weighing and Sorting Scale
The Maotong series weighing and sorting scale is a high-speed, high-precision online checkweigher designed for automatic weight inspection, tolerance verification, and weight-based classification or sorting within a wide range of automated assembly and logistics conveying systems. It can be seamlessly integrated into various packaging production lines and conveyor setups. With broad application in industries such as pharmaceuticals, food, toys, hardware, and chemicals, it also serves as a direct replacement for manual weighing—greatly enhancing production efficiency, consistency, and reliability.

Equipment Overview (see diagram):
The checkweigher consists of two sections: a matching section and a weighing section. Materials are fed at a constant speed through the matching section and then into the weighing section. The system determines whether the weighing data is acceptable or unacceptable. Acceptable materials are discharged, while unacceptable materials are alarmed and shut down.
