Introduction

    A fully automatic horizontal round bottle labeling machine is widely used for labeling unstable cylindrical objects such as oral liquid bottles, pen barrels, lipsticks, and other small round containers. It adopts a horizontal conveying and labeling method, which enhances stability and improves labeling efficiency.

    However, during operation, users may encounter issues such as label liner breakage, labeling misalignment, sensor malfunctions, unstable label dispensing, bubbles, wrinkles, or even complete machine failure. This article provides a detailed analysis of common problems and practical troubleshooting solutions to help you maintain smooth production.

1. Label Liner Breakage

Ø Possible Causes:

Low-quality label liner that easily breaks

Scratches on the liner during the feeding process

Labels sticking together, causing them to tear when pulled

Ø Solutions:
Choose high-quality glassine liners and ensure label suppliers control die-cutting depth to avoid damage to the liner.
Inspect the label path for any sharp edges that may cause scratches and adjust the feeding route.
Control the label dispensing length to ensure the next label does not stick to the previous one.

2. Labeling Misalignment

Ø Possible Causes:

Label tape deviation or misalignment with the conveyor

Slippage of the traction wheel

Product size variation affecting labeling precision

Ø Solutions:
Loosen the traction mechanism, gently pull the label back and forth to correct its path, then tighten the position-limiting rings
Adjust the tilt angle of the labeling head to ensure parallel alignment with the conveyor
Check for traction wheel wear or loose screws and tighten or replace the wheel as needed

3. Continuous Label Dispensing or No Label Dispensing

Ø Possible Causes:

Improper sensitivity setting of the label sensor

Label tape deviation, causing the sensor to miss label detection

Ø Solutions:
Adjust the sensitivity of the label sensor according to the manufacturer’s guide
Reposition the label sensor to ensure it properly detects the label

4. Loose Label Liner at Peeling Plate

Ø Possible Causes:

Traction speed is too low

Slippage in the traction mechanism

Ø Solutions:
Increase the traction speed appropriately
Tighten the traction roller locking screws to prevent slippage

5. Label Skipping Issues

Ø Possible Causes:

The distance between labeled objects is too small, causing multiple objects to be detected             simultaneously by the sensor

Labeling speed is too high

Ø Solutions:
Reduce the conveyor speed or adjust the labeling rhythm

6. Label Wrinkling or Bubbling

Ø Possible Causes:

The labeling belt is not parallel to the labeling surface

Label dispensing speed does not match conveyor speed

Ø Solutions:
Adjust the labeling belt angle to ensure uniform label adhesion
Reduce the label dispensing speed to match the conveyor speed

7. Machine Not Responding

Ø Possible Causes:

Power supply issues or a blown fuse

Internal wiring is loose

Ø Solutions:
Ensure the power supply is properly connected and check the fuse for any damage
If the issue persists, contact a professional technician for repair
