If the operator encounters trouble in the process of using the automatic quantitative packaging scale

The automatic quantitative packaging scale has a high degree of automation, and its use is also very convenient. The obtained weighing results and packaging quality also meet the requirements. It is a very ideal packaging weighing equipment. However, there are also operators who encounter troubles in the process of using the automatic quantitative packaging scale. For example, the automatic quantitative packaging scale does not make ingredients after it is started. What is the problem?

After connecting the automatic quantitative packaging scale to the power supply and turning it on, pressing the start button found that the machine did not respond, and the packaging scale did not make ingredients. In this case, you may wish to take the elimination method to eliminate the root cause of the fault, so as to take targeted solutions.

The first is to check whether the magnetic reed switch on the cylinder of the scale door of the automatic quantitative packaging scale is closed in place. When it is closed in place, a display will appear on the touch screen. Reed switch, it is enough to lock the reed switch after the display is displayed.

Secondly, check whether the working state of the automatic quantitative packaging scale is automatic. If not, just click the switch to return to normal. Next, check whether the pause button is pressed to self-lock; whether the pause in the manual operation interface of the touch screen is self-locking. If it is self-locking, please switch to the non-self-locking state.

In the process of using quantitative packaging scales for finished product packaging, one of the problems with high frequency is the over-tolerance phenomenon. Not only are there many reasons for the over-tolerance, but the same quantitative packaging scale may also have different degrees and different phenomena. Difference.

If each bag is out of tolerance, and the out-of-tolerance is very serious, it is necessary to observe the large material door, small material door or weighing hopper door first. It must be an abnormal phenomenon in one of them, and the closed one is not closed. In other words, if one of the large and small material doors or the scale hopper door is always open after the quantitative packaging scale starts feeding, it will cause the phenomenon of out-of-tolerance.

After careful inspection, it can be found that the solenoid valve of the corresponding material door is always electrified. After analysis, it is confirmed that this phenomenon occurs because the output relay in the quantitative packaging scale PLC is used due to high frequency. open. To solve this problem, just replace the output of one PLC and change its corresponding program.

If during the packaging process of the quantitative packaging machine, the out-of-tolerance phenomenon occurs only occasionally for several consecutive bags, and the out-of-tolerance value is not large, it means that the large material door does not move smoothly during the closing process, and there is an instant stuck phenomenon. Due to the fast flow rate of the finished product, the instant stagnation will cause a large number of finished products to fall into the weighing hopper, resulting in out of tolerance.
