Wuxi Jianying has introduced two automatic weighing and bagging machines, the BZJ-01 and BZJ-02, specifically designed to meet the quantitative filling requirements of powder and granular materials respectively, while adapting to diverse material properties and production conditions. Equipped with a mature mechanical structure and an intelligent electrical control system, these systems excel in operational stability, weighing accuracy, and safety protection. Their compact yet robust design ensures low failure rates and broad material compatibility, making them suitable for both conventional batch production and specialized automated packaging applications, thereby facilitating standardization and automation upgrades across industrial production lines. The key difference between the models lies in their bag retrieval mechanism: the BZJ-01 features a side-suction design that delivers higher packaging efficiency than the BZJ-02. Both models handle powder and granular materials used in chemical, metallurgical, pharmaceutical, and pesticide industries. With proven operational reliability, low learning curve, long-term stable performance, minimal measurement errors, and simple maintenance, they are ideal choices for routine automated packaging tasks in small-to-medium production lines.

Feature And Application
The automatic weighing and bagging machine is equipped with a high-speed automatic bag loading module, enabling unmanned operation throughout the entire process of bag retrieval, opening, and feeding. The equipment operates with uniform and stable rhythm, exhibits low failure rates, and supports prolonged high-load continuous mass production in factories, significantly enhancing packaging speed and production continuity across the entire line. Manual operation involves placing empty bags into the bag storage bin; a bag retrieval mechanism then lifts the bottom of the packaging bags from the bin, which are subsequently conveyed by a chain conveyor to the opening station.
A vacuum suction cup opens both sides of the bag opening, while a fork mechanism inserts itself into the opening to shape it. Finally, a robotic arm secures both sides of the packaging bag and transports it to the bag-clamping discharge unit.
Comprehensive safety interlock protection configuration across the entire system: All actuators integrate safety control and interlock mechanisms, featuring complete overload, material jamming, and fault-based automatic shutdown functions. This design balances equipment safety with personnel protection, reduces intermediate shutdowns, and ensures uninterrupted packaging operations.
