1.  Product Introduction

Heavy bag packing machine is engineered for granular materials like rice, beans, and animal feed in 10-20kg capacities.  This servo-driven system integrates weighing (±0.1% accuracy), bag forming, filling, and sealing at 500-600 bags/hour.  Key features include:

Multi-material compatibility: PP woven bags/kraft paper/plastic films

Triple sealing options: Sewing, heat sealing, or hybrid

Dust-proof design with pneumatic cleaning system

ISO 9001 & CE certified components

4.  Operational Guide

4.1 Pre-Operation Setup

Mount film roll (FFS models) or load pre-made bags

Calibrate load cells using 20kg test weights

Configure parameters via 10.1" HMI touchscreen:

Bag length: 700-900mm

Target weight: 10/15/20kg presets

Sealing temp: 150-180°C (plastic films)

4.2 Production Cycle

Automatic bag feeding → Position detection

Gravimetric filling via servo-controlled gates

Top sealing with batch coding (date/lot number)

Output via cleated conveyor (12m/min speed)

4.3 Maintenance Schedule

Daily:

• Clean residual particles from weighing hopper

• Check pneumatic filter moisture traps

Monthly:

• Lubricate chain drives with high-temp grease

• Inspect sealing jaw PTFE coatings

5.  Troubleshooting

5.1 Common Issues & Solutions

Problem: Inconsistent bag lengths

Solution: Adjust film tensioner pressure ±0.1MPa

Problem: Weighing fluctuations >±0.5%

Solution: Recalibrate load cells and check air cushion stability

Problem: Film jamming during forming

Solution: Realign forming collar and replace worn guide rollers

5.2 Error Codes

E101: Overweight alarm (check gate closure)

E205: Sealing temperature fault (verify thermocouples)

E307: Pneumatic pressure low (inspect compressor)

6.  FAQs

Q1: Can it handle recycled materials with varying density?

A: Yes, with optional vibration compactor for uniform packing

Q2: What's the ROI compared to manual bagging?

A: Typical payback in 12-18 months via 60% labor reduction
