The core features of the automatic weighing and packing scale are high precision and high efficiency. It employs a three-stage (fast, medium, slow) feeding control strategy combined with high-resolution load cells to ensure the weight error per bag is strictly controlled within the set range (e.g., ±0.2%). Fully automatic operation, from automatic bag hanging, quantitative filling to automatic bag dropping or conveying, greatly reduces labor intensity and costs. The user interface is friendly, allowing easy parameter setting (target weight, bag count, etc.), and includes data statistics and printing functions. It can be linked with bag sewing machines and conveyors to form a complete packaging line.

Specifications are usually defined by weighing range and speed. The common weighing range is 20-50kg/bag. Packaging speed depends on material characteristics and weight, generally between 200-600 bags per hour. Weighing accuracy can typically reach ±0.1% to ±0.3%. The equipment is equipped with a dust collection port to connect with the central dust removal system, maintaining cleanliness. The total power consumption is relatively low, mainly for the drive and pneumatic systems, typically 3-10kW.
