Troubleshooting Sealing Problems in Strapack Machine
Issue:
The Strapack machine is experiencing sealing problems, leading to incomplete or weak strap seals. Below are the main causes and step-by-step solutions to resolve the issue.
Heater Cable is Broken or Circuit Protector Shuts Down the Heater Circuit
Possible Causes:
Heater cable is
damaged or disconnected.
Circuit protector has tripped, shutting
off the heater circuit.
Solution:
Step 1: Check
the heater cable for any visible damage. If broken, replace it.
Step 2: Inspect the circuit
protector. If it has tripped, reset it and observe the machine.
Step 3: If the issue persists,
check the electrical connections and call a technician if needed.
Improper Temperature Setting
Possible Causes:
The heater temperature is too low or too high for proper sealing.
Solution:
Step 1: Check the heater temperature setting in the
control panel.
Step 2: Adjust the temperature according to the strap thickness and
material (refer to the machine manual for recommended settings).
Step 3: Test by running a few
straps through the machine and inspect the seal strength.
Too Much Tension (Especially on Hard or Small Packages)
Possible Causes:
Excessive tension
prevents proper strap fusion.
Small or hard packages cause
misalignment in strap sealing.
Solution:
Step 1: Reduce the strap tension setting on the
machine.
Step 2: Ensure the package size and hardness are suitable for the
selected strap tension.
Step 3: Run a test strapping cycle and adjust further if needed.
Heater is Not Inserted Between Straps
Possible Causes:
The heater is not correctly positioned between the overlapping straps, causing weak or no sealing.
Solution:
Step 1: Open the heater section and verify if the
heater is properly aligned.
Step 2: Adjust the heater position to ensure it is fully inserted
between the overlapping straps.
Step 3: Run a test cycle and check if the seal improves.
Strap Does Not Reach the Strap Stop Guide
Possible Causes:
The strap is misaligned or too short to reach the strap stop guide, preventing proper sealing.
Solution:
Step 1: Check
the strap feed and make sure it reaches the strap stop guide.
Step 2: Clean any dust or debris
from the strap path.
Step 3: Adjust the strap length
setting to ensure proper feeding and alignment.
Step 4: Run a test cycle and
verify if the issue is resolved.
