Common faults and handling methods of powder filling machine

Phenomenon 1: the device starts without any display.

Check and response: First, make sure that the power supply is correctly connected.

Phenomenon 2: The word "CHAO" appears on the display screen.

Reason analysis: This usually means that the electronic scale is overloaded.

Solution: quickly remove the items on the scale table, overload state should suspend all operations.

Phenomenon 3: Display screen flashes "E1".

Reason analysis: This is usually due to the small setting of the pulse number of the stepping motor, which may be due to the inaccurate quantitative calibration or the improper setting of the weight base value, or the large difference between the check items and the set value.

Solution: Interrupt the current state with the Exit key. After withdrawal, the number of stepping motor pulses will automatically recover to 3000. Subsequently, redo the quantitative calibration and accurately set the package weight reference value; reduce the operating frequency of the stepping motor if necessary.phenomenon

Phenomenon 4: The display screen prompts "E3".

Reason analysis: This usually means that the weight is not placed correctly when calibration the electronic scale.

Solution: Use Exit again to interrupt the current state and re-again.

Phenomenon 5: photoelectric switch reaction.

Cause analysis: it may be due to excessive dust accumulated on the photoelectric switch induction head, or its sensitivity is not set properly.

Solution: gently wipe the dust off the end surface of the photoelectric switch, and adjust its sensitivity appropriately. When wiping, ensure to enter the "bSZ" state.

Phenomenon 6: Although the photoelectric switch is blocked, the material does not fall.

Check and response: first, check whether the red light is on when blocking the photoelectric switch; second, measure whether the voltage of the photoelectric switch is normal (12V); again, check whether the signal line voltage is in the normal range (about 0V when blocked and about 11V when it is not blocked).

Phenomenon 7: Inaccurate feeding quantity.

Cause analysis: material too wet, lumps, feeding spiral steering error, spiral wound foreign body, mixer scraper improper position, unreasonable stepping motor frequency setting, wrong operation method (such as dripping or container blockage at the bottom of the material into the container), as well as the material level change, grid voltage instability and other factors may lead to this problem.

Solution: Check and adjust the above reasons to ensure the accuracy of feeding.

Phenomenon 8: Stepper motor lost the step.

Cause analysis: the step motor frequency setting is too high, the driver is damaged, or the foreign body mixed in the material increases the motor resistance may be the cause.

Solution: reduce the frequency of stepper motor; replace the driver if it is damaged; remove foreign matter from the material.

Phenomenon 9: The weighing results are not accurate.

Cause analysis: the sensor may be linear inconsistency or sensor damage.

Solution: Multiple ate sensor; replace it if it is damaged.

Phenomenon 10: Electronic scale zero drift.

Cause analysis: the scale table is unstable, nearby the airflow interference or the humidity of the control circuit board is damp.

Solution: the hot air of the electric blower drives away the moisture, and pay attention to the temperature control at 40~50℃, for about 10 minutes.

Phenomenon 11: the feeding quantity is gradually reduced to the spiral idling material.

Cause analysis: the mixing motor stops turning or the transmission chain falls off.
