Product Introduction

The 50kg High-Speed Heavy Bag Packaging Machine is engineered for precision weighing and automated packaging of seeds (e.g., rice, wheat, corn) into woven PP bags. With servo-driven filling technology and PLC control, it achieves ±0.1% weight accuracy at speeds up to 300 bags/hour. Its modular design integrates bag placement, filling, sealing, and palletizing, reducing labor costs by 70% compared to manual operations.

Key Features

Multi-Layer Sealing: Heat-sealing or stitching options with dust-proof flaps for seed preservation. Smart Sensors: Infrared detection for bag positioning and load cells for dynamic weighing. Hygienic Construction: Food-grade SUS304 stainless steel contact parts (optional for organic seeds). Energy Efficiency: 5.5kW servo motors reduce power consumption by 20%.

Technical Parameters

1. Core Specifications

Bag Types: Valve bags, open-mouth woven PP bags (400–600mm width). Weighing Range: 25–50kg (±50g tolerance for seeds). Speed: 240–300 bags/hour (adjustable via touchscreen). Power: 380V/50Hz, 8kW (stable under ±10% voltage fluctuation).

2. Optional Modules

Nitrogen Flushing: Extends seed shelf life by reducing oxygen content. Palletizing Robot: Auto-stacks 50 bags/pallet (max load: 2.5 tons). Data Export: CSV/XML production logs via Ethernet for traceability.

Application field

Agriculture: Hybrid seeds, grains, fertilizers (anti-static design for dusty environments).

Food Processing: Quinoa, beans, coffee beans (FDA-compliant models available). Export Packaging: ISO-compliant bagging for international shipping.

Operating Guidelines

1. Installation & Setup

Foundation: Concrete floor (load capacity >5 tons) with vibration dampeners. Calibration: Use 50kg test weights; adjust PLC parameters for seed density.

2. Production Workflow

Bag Loading: Automatic bag clamp secures empty bags (pneumatic pressure: 0.6MPa). Filling: Twin-screw feeder fills seeds at 12kg/sec (fast + precision modes). Sealing: Heat-sealer (180°C) or sewing head (8–12 stitches/inch). Output: Motorized conveyor transfers bags to palletizer (speed: 0.5m/s).

3. Maintenance

Daily:Clean residual seeds from hopper; inspect sealing strips.

Monthly: Lubricate servo motor bearings (Shell Gadus S2 V220 grease). Annual: Replace wear-prone parts (auger screws, load cell O-rings).

Troubleshooting

Common Issues & Solutions

Inconsistent Weight Cause: Seed bridging in hopper or sensor drift. Fix: Install anti-bridging vibrators; recalibrate load cells. Bag Misalignment Cause: Loose clamp pressure or misadjusted IR sensor. Fix: Reset clamp to 0.5MPa; realign sensor brackets.Seal Failure Cause: Contaminated sealing strip or low temperature. Fix: Clean strips with alcohol; increase heat to 200°C.
