Grain packaging machine calibration method

Food packaging machine calibration method We usually have a wide range of applications for food packaging machines because grain packaging machines reduce our labor force in industrial production. When we use the grain grain packaging machine to enter the automatic operation state, the weighing control system opens the feeding door and starts feeding. The feeding device is a two-step feeding mode of fast and slow feeding.

When the material weight reaches the fast feed setting value, stop the fast feed and keep the slow feed. When the weight of the material reaches the final set value, the feed door is closed and the dynamic weighing process is completed; at this time, the system detects whether the bagging device is in a predetermined state. After the packaging bag has been clamped, the system sends a control signal to open the weighing hopper discharge door, and the material enters the packaging bag. After the grain packaging machine material is discharged, the unloading door of the weighing hopper is automatically closed; after unloading the material, the clamp is released. Bag device, the bag falls automatically. After the bag falls, the bag is sewn and transported to the next station. This cycle runs automatically.

However, in the daily life, the grain grain packaging machine always has a malfunction phenomenon. This time, it is not simply a maintenance problem but also we have to weigh the grain packaging machine.

For example, the boot does not display, we should first check the sensor wiring is correct, open the control cabinet power and warm up for 15 minutes before correction. If this happens, it is usually a power failure or a blown fuse. In this case, you can use the digital multimeter to measure the resistance value to determine whether it is damaged or not. After replacing the damaged device, the weighing instrument can work normally. We should use the partial load adjustment to place the 10kg weights on the two weighing points of the weighing bucket. When the weighing indicator shows â€œpositive differenceâ€, the sensor output of the grain granule packaging machine should be adjusted to decrease direction; when the weighing display shows â€œnegative differenceâ€, the sensor output should be adjusted to increase direction.

If the grain grain packaging machine is weighing inaccurately or there is power indication but no data is displayed, it may be due to the instrument failure of the package weighing. The easiest way to do this is with an analog source search. The specific steps are as follows: Disconnect the signal cable from the junction box to the instrument, insert the socket of the analog signal source into the weighing instrument interface and turn on the power to see if the weighing instrument works normally. If the weighing instrument is not normal, the fault is in the weighing instrument. The exclusion of the failure must be carried out by a special inspection personnel. Junction box failure, check the junction box for water vapor intrusion. If there is water vapor, rub it with alcohol, and then dry it with a hair dryer to keep the interior clean.

In addition, if there is a short circuit in the search circuit, the grain packaging machine shall use the digital multimeter to measure the resistance of the shielded wire and other lines in the junction box, whether there is a short circuit phenomenon, or if there is a short circuit phenomenon,
You must replace the cable.
