Packaging machine common problems and solutions

In the daily use of the packaging machine, there are often many problems such as material breakage, uneven packaging film, tight sealing of the packaging bag, and inaccurate positioning of the color standard. Due to the limited technical ability of the operator in the packaging machine, it often leads to The packaging machine can't work normally. What is the reason why the packaging machine can't work normally? Let us take a look at the common faults of the packaging machine and how to solve it?

Fault analysis and elimination
malfunction the reason Method of exclusion
Pulling off the packaging material 1. The packaging material has joints and excessively broken edges. 2. The paper supply motor has a faulty line or poor line contact. 3. The paper supply proximity switch is damaged. 1. Remove the unqualified paper segments.
2. Overhaul the paper feed motor circuit.
3. Replace the paper feed proximity switch.
Bag sealing is not tight 1. The inner layer of the packaging material is uneven.
2. The sealing pressure is not uniform.
3. The sealing temperature is low.
1. Remove unqualified packaging materials.
2. Adjust the sealing pressure.
3. Increase the heat sealing temperature.
Improper road closure 1. The position of the heat sealer is incorrect. 1. Re-adjust the position of the heat seal body.
The bag is cut continuously or partially cut continuously to cause the bag

1. The position adjustment of the cutter is not suitable.
2. The cutter blade becomes dull.

1. Adjust the position of the cutter.
2. Grind or replace the cutter.
Heat sealer body does not heat up 1. The heating tube is damaged.
2. Line failure.
3. The insurance is broken.
1. Replace the heating tube.
2. Check the line.
3. Replace the fuse.
Heat sealer body temperature is out of control 1. The thermocouple is broken.
2. The temperature controller is damaged.
1. Replace the thermocouple.
2. Replace the temperature regulator.
The paper feed motor does not turn or turn around 1. The paper feed lever is stuck.
2. The paper supply proximity switch is damaged.
3. The starting capacitor is damaged.
4. The fuse is broken or the power board is faulty.
1. Solve the cause of the jam.
2. Replace the paper feed proximity switch.
3. Replace the starting capacitor.
4. Replace the fuse and check the power board to troubleshoot.
Color point positioning does not work 1. The set length of the bag length is not suitable. Usually, the actual bag length is less than the standard length of the color standard.
2, the roller pattern is smoothed, the friction is reduced
1. Increase the set value of the bag length so that the actual bag length is slightly larger than the standard length of the color mark.
2. Replace the roller.
Do not pull the bag (the bag motor does not work) 1. Line failure.
2, the pull bag proximity switch is damaged or the distance between the pull bag and the sending cam is far.
3. The control board is faulty.
4. The stepper motor driver is faulty.
1. Check the line to troubleshoot.
2. Change the pull bag proximity switch or adjust the pull bag to send the cam distance.
3. Replace the control board.
4. Replace the stepper motor driver.
The bag is always blocked above the cutter 1. The timing of pulling the bag is ahead of schedule.
2. The position of the upper bag is wrong.
1. Re-adjust the timing of pulling the bag.
2. Adjust the position of the upper bag.
The weight of the liquid machine package is unstable and not filled. 1. The cock rocker is loose.
2. The range of material level changes is large.
3, the pipeline is blocked;
4, the position of the cock is wrong
1. Tighten the cock rocker screw.
2. Control the range of material levels.
3, dredge the pipeline,
4. Adjust the position of the cock.
Filling motor does not work 1. The position of the filling proximity switch is improper; the control board is broken.
2, the drive, the filling motor is broken
1. Adjust the proximity switch position to send it; change the control panel.
2. Replace the drive or motor.
