2. Inaccurate Measurement (Large Weight Fluctuation) When a powder packaging machine malfunctions during operation, quickly locating and resolving the issue can effectively reduce downtime. Below are quick troubleshooting and solutions for common malfunctions, categorized by malfunction type:
I. Feeding System Malfunctions
1. Powder blockage/no material discharge
Quick Solution:
✅ Check the hopper: Pause the machine and manually clean any caked powder (especially moisture-sensitive powders such as milk powder and starch).
✅ Vibration/pneumatic assistance: If pneumatic feeding is used, check that the air pressure is ≥0.6 MPa; for vibration feeding, adjust the amplitude.
✅ Auger feeder: Remove the auger shaft and clear any winding or residual powder (remember to power off!).
Quick Solution:
✅ Calibrate sensor: Recalibrate the weighing module using standard weights (refer to the instruction manual).
✅ Check auger speed: Ensure that the motor speed is stable and there is no slippage (reset or replace the inverter if there is a malfunction).
✅ Powder flowability: If the powder is very humid, add desiccant or use vibration feeding assistance.
II. Sealing Issues
1. Poor sealing (powder leakage)
Quick Solution:
✅ Temperature check: Is the sealing temperature too low? Increase it by 5~10℃ (different packaging materials require adjustments, such as PE film usually 130~180℃).
✅ Pressure adjustment: Increase the sealing cylinder pressure or check for air leaks in the air bag (pneumatic type).
✅ Sealing time: Extend the sealing time by 1~2 seconds (especially for thick film materials).
2. Seal cannot be cut or has burrs
Quick Solution:
✅ Blade cleaning: After stopping the machine, wipe the cutting blade with an alcohol wipe to remove any adhering molten residue.
✅ Blade pressure: Adjust the cutting blade pressure screw to ensure even pressure on both ends.
✅ Replace blade: If the blade is dull (common after continuous operation), replace it with a new blade.
