Introduction

The Automatic Open Mouth Bagging Machine represents a technological leap in bulk material packaging, specifically engineered for rice, beans, and similar granular commodities. With weighing accuracy reaching ±0.1% and operational speeds exceeding 250 bags/hour, this system combines German-engineered load cells with Japanese servo motors for unparalleled reliability. The modular design accommodates diverse production environments while maintaining compliance with ISO 9001 and CE standards.

Technical Specifications

Powered by a 380V electrical system with 5.5kW consumption, the machine features a stainless steel contact surface (SUS304) resistant to corrosion and abrasion. The pneumatic clamping system operates at 0.6-0.8MPa pressure, accommodating bag sizes from 25kg to 50kg with optional extensions for 1000kg jumbo bags. The integrated PLC control panel supports 12 language interfaces and generates real-time production reports via Ethernet connectivity.

Critical components include: Twin-screw feeding mechanism with anti-clogging design Laser-guided bag positioning sensors Dual-stage dust collection system (3000m³/hr capacity) Optional nitrogen flushing module for oxidation-sensitive materials

Application Scenarios

In agricultural processing plants, the machine handles paddy rice, milled rice, and various bean varieties (soybeans, mung beans) with minimal product breakage. Chemical manufacturers utilize its sealed version for packing fertilizer pellets and industrial compounds. The food-grade variant meets HACCP standards for sugar, salt, and flour packaging. Special configurations exist for: Valve-type bag filling in cement plants Heat-sealed packaging for hygroscopic materials Palletizing-integrated systems for automated warehouses

Operational Guidelines

Installation PhaseFoundation preparation requires a 150mm thick concrete base with M20 anchor bolts spaced at 400mm intervals. Pneumatic connections should use 8mm diameter polyurethane tubes with quick-release fittings. Electrical wiring follows IP65 protection standards with separate grounding (<4Ω resistance). Daily OperationThe four-step workflow begins with bag placement on the servo-controlled clamp, followed by: Gross weighing phase (fills 90% capacity in 3 seconds) Precision dosing (achieves target weight within ±50g) Automatic bag shaking for product settling Stitch or heat sealing (configurable 150-200°C)

Maintenance Protocol

Weekly tasks include auger screw inspection for wear and torque verification (35±2 Nm).

Monthly maintenance involves:

Load cell calibration with certified test weights

Dust filter replacement (HEPA Grade H13) Conveyor belt tension adjustment (deflection<5mm)

Troubleshooting MatrixSymptom:

Inconsistent Fill Weight

Possible causes:

Material bridging in hopper (resolve with vibrator activation) Compressed air pressure fluctuation (maintain 0.7±0.05MPa) Load cell contamination (clean with anhydrous ethanol) Symptom: Bag MisalignmentSolutions: Adjust photoelectric sensor angle (30° optimal) Replace worn clamp pads (thickness<8mm triggers alert) Recalibrate conveyor tracking (center tolerance ±2mm)
