Inadequate action of particle packing scales and troubleshooting of material door failure

Inadequate action of particle packing scales and troubleshooting of material door failure
Recently, I have encountered some troubles when using the packaging scales. Fortunately, there are some minor problems that can be properly resolved with a little adjustment. Although the problem of packaging scales is small, if it cannot be ruled out in time, it may also have a great impact. Therefore, it is necessary to fully grasp these skills.
One of the common problems is that the pneumatic actuator of the packaging scale is stuck and the action is not in place. The analysis proves that this is due to the high moisture content in the compressed air during the packaging process. In this case, you need to replace the engineering molecular sieve in the packing scale, and regularly drain the gas source triplet, and do not forget to regularly add grease to the actuator.
If the electromagnetic valve of the packing scale is faulty, the PLC signal of the equipment will be output, and the solenoid valve body will be stuck, causing the actuator to not move. This again reminds users that it is necessary to regularly check the solenoid valve movement in the packing scale, and disassemble the valve body in time to clean and add grease.
There is also a problem that when the start button of the packing scale is pressed, the large and small material doors cannot be opened and feeding is impossible. The analysis proves that the reason for this phenomenon is that the packaging scales have not been used for a long time, and there are still a certain number of finished products in the hoppers, causing this phenomenon to occur.
In a similar situation, the first step is to clear the hopper of the packing scale, and then clear the value of the meter. In order to avoid the recurrence of this phenomenon, if the packaging scale is not used for a long time, be sure to clear the hopper in a timely manner to keep the empty state.
