Common fault inspection and troubleshooting methods of powder quantitative packaging machine!
Title: Common fault inspection and troubleshooting methods of powder quantitative packaging machine! and equipment will inevitably have some small faults in daily use. For enterprises in industry, the machines in the workshop suddenly fail during normal operation. These questions are really annoying. Because the failure of computer automatic packing machine will not only reduce packaging efficiency, delay delivery, but also affect packaging safety, especially packaged food. In fact, it is normal for a factory's packaging machine (perhaps some part of the machine) to fail. Caused by aging or loosening. If the fault is to be solved as soon as possible, maintenance personnel need to have a relative understanding of the machinery, understand the health of the machinery, which parts are seriously damaged, and which parts are easy to loose. Some common faults and solutions of powder quantitative packaging machines. 1. The pulse cannot be transmitted to the electrical control cabinet This may be caused by the high sensitivity of the photoelectric switch of the powder quantitative packaging machine or blocked. At this time, please adjust the photoelectric sensitivity to an appropriate position or remove the obstruction. 2. Pulse increase weight decrease After adding material, the actual weight is out of tolerance. This is caused by different material levels in the hopper. After adjusting a few bags, it can go back to normal. Therefore, it is necessary to reasonably control the material level in the hopper (manual feeding) or adjust the preset number of bags (automatic feeding). 3. The zero point of the calibration weigheris unstable. There may be a large airflow (such as wind, electric fans, air conditioners) or vibration sources. Also, this phenomenon can occur if the board is wet due to high ambient humidity. At this point, carefully remove the scale's casing and use a hair dryer to blow away any moisture. Note: The hair dryer should not be too close to the circuit board, nor should it be heated for a long time to drive away moisture, so as not to damage the components. 4. The screw does not move or the measurement result is good (1) There are sundries in the material, resulting in excessive resistance or eccentricity of the material cup. In this case, please close, remove the material cup, remove debris or adjust the position of the material cup; (2) The operator can change the operation method by leaning the bottom of the container against the outlet of the material cup. 5. Inaccurate measurement after changing packaging specifications or materials (1) The position of the stirrer scraper is not suitable and needs to be adjusted so that the lower end of the scraper is about 10-15mm away from the spiral; (2) If there is leakage after filling, please add Leak-proof net. 6. The stirring motor does not run (1) The powder quantitative packaging machine will inevitably cause some machines to heat up during the operation process, and the thermal overload relay will trip. At this point, open the electrical control cabinet and you will see that the thermal overload relay trip indicator (green) has been pushed out. The cause of the fault is the excessive load of the stirring motor or the vibration when it stops. (2) The power supply is out of phase. 7. The motor cannot work normally or cannot work (1) If the grid voltage fluctuates too much, the drive power will be turned on and the driver power will lock itself; (2) The running frequency is too high, causing the stepper motor to lose steps. 8. The following faults will occur when the power supply voltage is too low (1) The driving power supply is self-locking; (2) The weight of the calibration weigheris unstable; (3) The check scale shows confusion; (4) The stepper motor is out of step, and the driving power supply Call the police.
