Automatic Fertilizer Packaging Machine with PLC Control System for Granular Fertilizer at 480-600bag/h in Carbon Steel Construction

The BLD-K50/S fully automatic packing machine addresses labor shortages, rising labor costs, and inconsistent manual operation quality in the granule industry. Utilizing PLC control systems, it performs bag positioning, inner bag thermal sealing, bag sewing, and labeling operations.

This intelligent packaging system connects with weighing equipment and palletizing equipment to achieve fully automated production, with capacity reaching 500-600 bags per minute. Designed specifically for granular and irregular materials, it employs pneumatic gate feeding or belt feeding modes with advanced electrodeless frequency conversion technology.

The machine requires manual placement of empty bags and labels, with storage capacity for 400 labels and 300 empty bags. The storage system includes alarm functions to alert operators when supplies are running low.

• Empty Bag Inspection: Bags are checked before filling position; damaged, curved, or improperly sealed bags are automatically rejected
• Bag Placement Monitoring: System signals weighing scale to prevent failure filling when bags are incorrectly positioned
• Sewing Error Detection: Alarms activate for label unavailability, broken sewing lines, or particle interference; system halts until issues are resolved

The quantitative filling and packaging scale machine comprises four main components: automatic weighing, conveying equipment, bag sealing equipment, and computer control systems.

• Dual-frequency spiral propulsion with dual-cylinder measurement
• Advanced digital frequency conversion control technology
• Automatic error compensation and correction capabilities
• Reasonable structure with stable operation and energy efficiency
• User-friendly operation with precise weighing accuracy
