The causes of common failures of packaging scales and the correctness of the inspection method for handling failures are very important for quickly and accurately determining the location of the failure and retreating it. Here to tell you about the common quantitative packaging scale fault and its processing methods. If the weighing of the packaging scale is inaccurate during work, it may be the elastic deformation of the weighing sensor, the linearity is poor or the sensor is broken, and the linearity can be judged by multiplying the standard weight to see whether the output display is proportional to it. It is also possible that the boom of the sensor is in contact with the outside world and is caused by the vibration and action of the outside world. It is also possible that the opening of the feed gate is too large, the impact force is too strong, and the target value is exceeded, and the fine feed is too late to control. It is also possible that the incoming materials are uneven and the drop compensation value is not well controlled. The cps value fluctuates greatly, resulting in more and less weighing time. It is also possible that the cylinder and solenoid valve are slow in action, resulting in a fast shut-off of the feed, resulting in excessive weighing. It is also possible that the signal fluctuation caused by the oxidation and poor contact of the wire joint of the weighing sensor, resulting in unstable weighing. It is also possible that the welding around the sensor is disturbed by strong current, resulting in signal instability and weighing fluctuations. It is also possible that the grounding resistance of the system cabinet and sensor shielding network is large, and the anti-interference is reduced.
