Pillow Packaging Machine Fault Diagnosis and Solutions

The pillow packaging machine common Fault Phenomena and Immediate Solutions

1. Film Feeding Issues

• Cause: Machine stops due to empty film roll

• Solution: Replace with new packaging film immediately

2. System Control Failure

• Cause: Controller self-check failure alarm

• Solution: Contact original equipment manufacturer; press ESC to reset system if fault clears

Five Critical Fault Phenomena Analysis

1. Color Mark Misalignment

• Primary Causes:

  • Color mark tracking function disabled

  • Faint color mark contrast

  • Film drive slippage

2. Product Damage During Cutting

• Root Problems:

  • Push rod and cutter timing mismatch

  • Improper knife seat height adjustment

  • Excessive packaging speed

3. Seal Burn Marks

• Contributing Factors:

  • Overheating of sealing elements

  • Insufficient machine speed

  • Poor heat resistance of packaging film outer layer

4. Weak Seals or Leakage

• Key Reasons:

  • Inadequate sealing temperature

  • Excessive operational speed

  • Substandard inner layer heat seal properties

5. Temperature Control Failure

• Potential Component Failures:

  • Damaged heating elements

  • Burned out solid state relays

  • Faulty thermocouples

  • Defective temperature control module

Comprehensive Troubleshooting Guide

For Tracking and Cutting Issues:

1. Activate “Tracking Cut” mode in HMI interface

2. Adjust electric eye sensitivity per manual specifications

3. Calibrate glue stick pressure or brake tension

For Mechanical Synchronization Problems:

1. Realign push finger position as per technical manual

2. Adjust end seal component height to center on product

3. Reduce packaging speed for better synchronization

For Thermal Regulation:

1. Recalibrate temperature settings

2. Optimize machine speed parameters

3. Consider upgrading to higher quality film materials

Component Replacement Protocol:

1. Swap damaged heating elements

2. Install new solid state relays

3. Replace faulty thermocouples

4. Upgrade defective temperature control units

Preventive Maintenance Recommendations

• Regularly inspect film tracking systems

• Monthly calibration of thermal components

• Quarterly verification of mechanical synchronization

• Annual comprehensive system diagnostics
