Many people who have purchased a hot melt adhesive labeling machine know that machine debugging is actually very energy-consuming and time-consuming for people who have no experience and understanding. Perhaps, if you spend a high price to buy a good equipment without complete after-sales guidance and common sense about equipment debugging and operation, users will still feel that the equipment has many problems. People will have red lights because they don’t rest, not to mention that the equipment needs to continue running for a long time. There will also be some big and small problems for a long time. Today, we have summarized some common problems about hot melt adhesive labeling machines. .

1. The labeling machine cannot move the label

2. The labeling machine clicks on the continuous label

3. Click the labeling machine once to give two labels.

4. The labeling machine automatically does not label

5. When materials pass through the labeling machine, multiple labels will appear.

6. The label accuracy is poor and the effect is not up to standard.

7. The labeling machine often breaks the label

Next, let’s talk about the above issues. Where should we investigate them.

1. If there is a problem that the label cannot be moved, we need to pay attention to the PLC program, label feeder, label sensor, power supply, servo driver, etc.

Check that the PLC program is not downloaded or the PLC dials when it is stopped: we need to re-download the corresponding program and dial the PLC to the running state;

2. Check whether the label feeder is closed: we need to open the label feeder;

3. Check whether the bidding speed of the labeling machine is set to 0, and the bid will not be issued. We need to reset the bidding speed; make sure the machine has operating indicators;

4. Check whether the maximum bid length of the labeling machine is set to 0. We need to check the labeling machine. The MAX bid length is generally set to 2-3 times the actual label length;

5. Check whether the label sensor PLC input point of the labeling machine is connected incorrectly. You need to check whether the sensor input signal point is correct;

6. Check whether the servo drive and motor are powered on or press the emergency stop button. You need to loosen the emergency stop button, check the line status, and ensure that the power supply is connected;

7. Check whether the servo drive parameters are set. You need to set the parameters according to the setting table, and then cut off the power and restart;

8. To check whether the servo driver has a fault alarm, you need to reset the parameters or replace the driver; make sure it is normal.

2. If there is a problem with jogging continuous labels, details such as label sensors are required.

1. In order to check the label electric eye failure, we need to reset the sensitivity of the label electric eye until the label and backing paper have stable output; at this time, the electric eye state returns to normal;

2. Check whether the pre-label length is set too large. We need to ensure that the pre-label length value cannot be greater than the actual label length value;

3. Before checking the label sensor signal, we need to clean up the debris and reset the parameters;

4. We need to replace the label sensor to check whether the label sensor is damaged (it must first be determined whether it is damaged), whether the NPN or PNP signal is the same, and whether the voltage is consistent);
