During the on-site commissioning and production process of automatic quantitative packaging scale weighing packaging machine products, the following problems sometimes occur. A simple analysis is as follows:
1. When the automatic quantitative packaging scale works, there is no bag clamping, and the scale bucket cannot discharge materials. This situation is usually caused by the bag clamping and bagging switch, as well as the solenoid valve and cylinder controlling the bag clamping.
2. The size feeding door of the automatic quantitative packaging scale, the hopper discharge door cannot be opened or the discharge door cannot be closed. After the mechanical failure is eliminated, it is generally the problem of the cylinder and the control solenoid valve.
3. After the weighing of the material weighing bucket, the automatic quantitative packaging scale cannot automatically open the blanking door for discharging and loosening the bag. If you press the manual discharging button, it will not work. Generally, there is a problem with the solenoid valve or cylinder controlling the material door, and it will return to normal after replacing the spare parts.
4. Material leakage at the bucket mouth or bag mouth of the automatic quantitative packaging scale is usually caused by the loose sealing of the scale body, insufficient air pressure (check the air source is greater than 0.4MP) solenoid valve or cylinder.
5. The automatic quantitative packaging scale is inaccurate, and the instrument display is unstable. It may be the zero drift of the instrument (recalibration of the standard weight is required) or the parameter setting needs to be corrected again, or it may be the fault of the weighing sensor (check and replace the calibration of the sensor weight)
6. If the system cannot discharge materials normally, set the selection switch to manual.
