Ewinall QZB-1600 5-25kg Fully Automatic Woven Bag Packaging Machine | High-Speed Grain, Rice & Seed Packing

Double the Throughput, Half the Labor – The QZB-1600 Redefines Industrial Bagging

When your production line demands 5-25kg bags of rice, seeds, grains, or fertilizers at a pace that manual or semi-automatic machines cannot sustain, the Ewinall QZB-1600 Fully Automatic Packaging Machine steps in. This industrial-scale unit uses a unique double-station design to achieve 700 to 1,400 bags per hour, nearly doubling the output of conventional single-station packers.

Built for woven bags—whether flat, buckle-handle, or edge-folded—the QZB-1600 handles the entire sequence: automatic bag feeding, opening, precision weighing, filling, and sewing, without operator intervention. A touch screen with PLC centralized control and servo-driven transmission let you switch products in seconds. If you package rice, seeds, feed, sugar, or other granular bulk materials in woven bags and need a fully automatic bagging machine that scales with your business, this is the machine your line is missing.

What Makes the QZB-1600 a Production Powerhouse

• Double-Station Design for Maximum Speed
  While one station fills and seals a bag, the other is already positioning the next. This overlap cuts idle time and pushes throughput to up to 1,400 bags per hour, making the QZB-1600 one of the fastest woven bag packaging machines in its class. Mills, processing plants, and contract packers that struggle with seasonal spikes find this speed critical.
• One-Click Product Changeover
  Switching from 5kg long-grain rice to 25kg soybean meal? Select the pre-saved recipe on the MCGS touch screen. The machine automatically adjusts the quantitative scale, bag size parameters, and sewing position—no manual mechanical recalibration required. This automatic woven bag packing machine turns product changeovers into a 10-second task.
• True All-in-One Automation: Feed, Fill, Sew
  The combined automatic bag feeder works with flat woven bags, buckle-handle bags, and edge-folded bags. It picks a bag, opens it cleanly, positions it under the filling spout, and releases it only when the target weight is confirmed. The integrated sewing head then closes the bag securely and uniformly. Every bag emerges with a consistent weight and a neat, professional seal.
• Servo-Driven Precision Weighing
  The quantitative scale uses a servo motor for feeder control and a three-sensor load-bearing structure for fast, accurate weight measurement. All weighing components are housed in a sealed, dust-proof chamber, protecting sensitive electronics from the corrosive dust and humidity common in grain and fertilizer plants. This extends component life and maintains measurement accuracy over years of continuous operation.
• PLC Centralized Control & Servo Transmission
  Omron PLC and servo drives (Inovance) coordinate every motion—bag feed, clamp, fill, sew, and discharge—with precise timing. The system constantly monitors motor loads, sensor signals, and air pressure. When something goes wrong, a fault self-check system displays an easy-to-understand prompt on the screen, so your line technician can identify the issue without scrolling through cryptic codes.
• Safety by Design
  Full perimeter guarding, safety interlock doors, and enclosed moving parts (bearings, chains, sewing mechanism) meet international safety expectations. The machine is grounded with a TN-S system, and all electricals (Eaton low-voltage components) come with overload and leakage protection.
• Built for Tough Environments
  The frame is heavy-duty steel, powder-coated to resist rust. The sealed weighing chamber, IP-rated sensors (Sick photoelectrics, Omron proximity switches), and Japanese SMC/Airtac pneumatics ensure this industrial bagging equipment keeps running even in dusty, high-humidity rice mills and feed plants.
