What are the common faults in powder packing machines? What should be done?

Any machine that has been in use for a long time will have some problems.
in order not to affect the normal operation of the machine, operators need to master some common fault repair knowledge.
the following is a summary of the common failures and repair methods of powder packaging machines, hoping to help everyone.
1, the powder packaging machine spiral does not move (i.e., stepper motor blockage) or the measurement results may be good or bad phenomenon may be: (1) there are impurities in the material, resulting in too much cup body resistance or eccentricity.
, close, remove, remove impurities, or position the cup.
(2) the operator places the bottom of the container at the mouth of the cup and changes the operation method.
2, after changing the packaging specifications or material measurement is not accurate, may be: (1) the mixer position is not suitable, need to adjust, so that the distance between the lower end of the knife and the helix is about 10-15 mm.
leakage occurs after filling (2) and the leak-proof net is added.
3, hybrid motor does not work: (1) heat overload relay release.
when you open the electrical control cabinet, you can see the hot overload relay trip indicator (green) eject.
caused by vibration when the mixer motor is under heavy load or when it is shut down.
(2) the power supply is out of phase.
4, stepper motor does not work properly or abnormally: (1) the power grid voltage fluctuations too large, drive power alarm light on, drive power self-locking.
(2) operating frequency is high, causing the stepper motor to be out of step.
5, the supply voltage is too low, there will be the following faults: (1) packaging machine drive power supply self-locking phenomenon.
(2) the weight of the calibration scale will also be unstable.
(3) If the voltage is too low, the calibration scale will show confusion.
(4) stepper motor may be out of step, driving a power alarm.
