The Wuxi Jianying A2 single-scale and B2 dual-scale series gravity-feed small bag packaging machines are specialized equipment designed for net-weight-based packaging of 20–50 kg granular materials in small bags.Featuring a core configuration combining gravity feeding with sealed-door material distribution and a high-precision intelligent weighing control system, these machines are suitable for standalone use on medium-to-small production lines and can be integrated with sealing machines and conveyors to form simple automated packaging lines.
This net-weight gravity feeding bag packaging machine operates with manual bag insertion and automated weighing/dosing; after material filling, bags are manually replaced. It features simple operation and low learning curve, combining exceptional cost-effectiveness with stable measurement accuracy, low failure rates, and easy maintenance, making it a fundamental and widely adopted packaging solution for the fertilizer, chemical granules, and plastic particles industries.

Feature And Application
The gravity-fed small bag packaging machine features a stable discharge structure that prevents clogging, jamming, and bridging: The A2 series employs a gravity-sealed door discharge mechanism, enabling rapid filling of large batches and precise feeding of small batches through a graded material control system, thereby enhancing filling efficiency. Its sealed design provides excellent dust prevention, effectively avoiding particle blockages, clogging, and bridging issues; even for crystalline particles with moderate flowability, it ensures continuous and stable discharge, demonstrating superior adaptability.
One-click parameter adjustment for rapid production switching across multiple specifications: The equipment features an intelligent human-machine interface that allows digital setting of packaging target weights, with seamless switching within the 20–50 kg range. No mechanical adjustments are required during production changes; specification switching takes only 1–2 minutes, significantly reducing downtime for material replacement and meeting diverse production demands for various product categories and specifications.
Intelligent dynamic compensation ensures stable measurement accuracy: Equipped with a fully computerized intelligent weighing control system featuring an integrated automatic air-drop compensation algorithm, it dynamically adjusts residual material quantities in real time, consistently maintains packaging precision, eliminates weight deviations, and achieves high product qualification rates.
Automatic data statistics and intelligent production management: The equipment features a built-in smart output counter that automatically records the total number of packages per shift and the total material weight, facilitating enterprise-level team capacity assessment and production review. It comes standard with communication interfaces for direct integration with the factory's DCS central control system, enabling remote data upload and visualized monitoring.
Simple and hassle-free operation and maintenance that reduces production costs: The equipment features a streamlined and rational design with stable performance, resulting in low annual maintenance material costs under standard operating conditions, low failure rates, and high durability. It is highly suitable for the routine production needs of small and medium-sized factories, effectively saving on both operational manpower and material expenses.
Highly compatible and easily expandable: The equipment demonstrates excellent adaptability, seamlessly integrating with vertical packaging machines, belt conveyors, dust removal systems, metal detectors, and other devices to rapidly establish a complete automated packaging line. It also supports customized upgrades as needed, including conversion into explosion-proof models or fully stainless steel corrosion-resistant versions, making it suitable for various specialized production environments.
