After the filling scale instrument is used, the dust and impurities contained in the equipment should be removed, not only to prepare for the next use, but also to maintain the equipment.

The filling scale instrument also needs to regularly check the use of the various components of the filling scale instrument, and cannot be used reluctantly, otherwise the equipment will have a big leak, so in order to effectively ensure the weighing quality of the filling scale instrument And to extend the service life of the filling scale instrument, it is necessary to do a good job of imitation. The debugging and maintenance skills of the filling scale instrument are as follows:

1. After the power is turned on and started, the quantitative packaging machine enters the automatic operation state, and the feeding device does not start.

Weighing display controller control process error, re-select." The electrical control element connected to the feeding device is damaged, replace it.

2. In the working state, after the bag is clamped, if the weighing display value reaches the quantitative value, the material will not be unloaded

The electrical control element corresponding to the unloading output of the weighing display controller is damaged, replace it." The solenoid valve that controls the unloading is damaged and does not operate, replace it.

3. The clamping force of the bag clamping device is insufficient, and the air source pressure is insufficient. Check the air source equipment. The trachea is damaged, the gas leaks, and the damaged trachea is replaced. If there is gas leakage at the air path connection, re-seal. The solenoid valve is faulty, if it cannot be repaired, replace it.

3. There are many parts that need to be cleaned on the filling scale instrument, and the timing of cleaning is also critical. After completing the packaging and weighing work, the first thing to clean is the measuring part of the filling scale instrument, such as the feeding tray, turntable, etc., Make sure it is not corroded.

4. There is a high-tech component on the filling scale instrument, which is also the focus of cleaning, such as the photoelectric tracking light-emitting head. Keeping it clean will help reduce the error of cursor tracking.

5. For the materials scattered on the material tray of the filling scale instrument, it may be cleaned in time, and the spray cleaning machine of the parts should be kept clean.

6. At the same time, the dust in the electric control box should be cleaned regularly to prevent faults such as poor contact.

7. Static verification out of tolerance, re-calibrate the scale.

8. For the newly installed filling scale instrument, after using it for a period of time, do not forget to check and refuel each transmission and moving parts to ensure its tightness and lubricity.

10. At the same time, check the screws of each part of the filling scale instrument regularly to avoid loosening.

12. Check the tolerance of eccentric load, and re-adjust the eccentric load.

12. The weighing data is inaccurate and fluctuates greatly.

14. For the electrical part of the filling scale instrument, the focus of maintenance is on waterproof, moisture-proof, anti-corrosion, etc., so as to avoid electrical failures.

15. Even when the machine is shut down, pay attention to maintenance. The 2 heat sealing rollers should be in the open position to prevent the packaging material from being scalded and affecting the packaging quality.

Check whether there is any foreign object colliding with the weighing bucket, and eliminate the collision factors. If the weighing sensor is not working properly, check the cause and eliminate it. If it is damaged, replace it. The limit device is in contact with the sensor, and the limit is adjusted to a reasonable gap.

18. The weighing display controller is not at 0 after starting up! Press the clear 0 key to clear it and continue working. If it cannot be cleared by pressing the clear 0 key, it may be that the 0 point of the weighing sensor is too large, and the scale needs to be recalibrated, such as Still can't solve the sensor replacement.

The filling scale instrument should be operated in a relatively dry place and in a well-ventilated environment during the working process. No debris is allowed around the equipment. When using it, the grounding of the equipment should be done well. Generally Under normal circumstances, precision instruments are prone to static electricity. If it cannot be eliminated in time, it is easy to damage the equipment.
