It sounds like you’re experiencing an issue with a jar lid packing machine where the lids are getting crushed during the packaging process. Here are some potential causes and solutions:

Possible Causes:
1. Incorrect Machine Settings
– The pressure or speed of the machine may be too high, causing excessive force on the lids.
– The alignment of the sealing mechanism may be off.
2. Improper Lid or Jar Fit
– Lids might be slightly oversized or misaligned before sealing.
– Jars may not be positioned correctly in the packing line.
3. Worn-Out or Damaged Components
– Worn-out conveyor belts, misaligned guides, or damaged sealing heads could cause crushing.
– Check for mechanical wear and tear.
4. Material Issues
– Lids might be too thin or made of weak material that deforms under pressure.
– If using metal lids, check for dents before packing.
5. Vibration or Instability in the Line
– If .jpg)
machine vibrates excessively, jars/lids may shift and get crushed.
Troubleshooting Steps:
1. Adjust Pressure & Speed
– Reduce the sealing pressure and check if crushing stops.
– Slow down the conveyor speed to allow proper alignment.
2. Inspect Alignment & Guides
– Ensure jars are properly centered before entering the sealing station.
– Adjust guide rails to prevent misalignment.
3. Check for Mechanical Wear
– Inspect belts, rollers, and sealing heads for damage.
– Replace any worn-out parts.
4. Test with Different Lids/Jars
– Try a batch with known good lids to see if the issue persists.
– Ensure lid size matches jar specifications.
5. Monitor Machine Stability
– Secure loose components and dampen vibrations if present.
Preventive Measures:
– Regularly calibrate and maintain the packing machine.
– Use quality control checks on lids before packing.
– Train operators to detect early signs of misalignment or excessive pressure.
If the problem persists after these checks, consult the machine manufacturer for technical support or consider professional servicing.
