Analysis of common failure causes of automatic weighing machines
The following checkweighing machine manufacturers analyze the common failure causes of automatic weighing machines: 1) Why is the equipment weighing inaccurate? A. Check whether other items touch the weighing tray; B. Whether the equipment is calibrated and can be re-calibrated; C. Whether there is wind blowing against the equipment; D. Compare whether the static weighing and dynamic weighing are consistent, if not It can be corrected by 'dynamic learning'. 2) The rejection device does not work? A. First check whether the power supply is connected normally; B. The power supply is normal, and then click the corresponding 'rejection port' in the fault detection to see if it works; C. If it does not work, check whether the right rejection port is selected in the rejection port. 3) Static weighing does not match dynamic weighing? The weight of the object is in two states of static and winter, and there is an error in the weighing result itself, which can be corrected by 'dynamic learning'. 4) Conveyor belt not running? A. When all conveyor belts are not running: check the power supply; B. When one or two sections are not running: You can check whether the motor is driven by reversing the motor and driver; 5) Conveyor belt problem 1) If If there is abnormal operation of the equipment or deviations in accuracy and speed, please check whether the conveyor belt of consumable parts is cracked; 2) Check whether the conveyor belt is deflected. If there is deflection, adjust the adjustment devices on both sides until the belt has no deflection; 6) Accuracy and speed problems 1) Check whether the conveyor belt is cracked or deflected, such problems can be replaced or adjusted to the normal position before testing; 2) Check the operation interface, whether the parameter settings are correct; parameter setting problems , You can reset the value to be set according to the manual, and use the actual product for 10 times to check whether the accuracy is stable; 7) After disassembling or inspecting the equipment, correctly reset the connectors and parts that were disassembled for inspection. Please reset it correctly. 8) If the failure is not caused by equipment factors, such as sudden environmental changes, abnormal power supply caused by lightning or abnormal voltage, falling or impact of the machine, or direct accident causes that are not caused by normal use, it is necessary to conduct a comprehensive inspection. Checkweigher manufacturers believe that regular maintenance can not only save costs, but also make production work normally.
