Many problems often occur during the use of the equipment. For example, when the paper bag machine is in use, temperature instability or no color label signal may occur. Many people do not know how to deal with this. In order to find the corresponding fault solution, you must first know what the cause of these faults is, and then you can prescribe the right medicine. Today, let's talk about the possible reasons for the temperature instability of the paper bag machine or the colorless signal.
The reasons for unstable temperature are as follows:
1． The walking of other wires interferes with the temperature or is caused by a short circuit.
2． There is a problem with the motherboard in the computer, and accurate judgment of this problem requires certain expertise.
3． Inspect the thermocouple for looseness and shedding;
4． Whether the set temperature corresponds to the set sealing knife;
5． Whether the sealing knife is installed tightly;
6. Whether the wires are scorched and loose;
7. Whether the switch in the electric cabinet is turned on;
It should be noted that when the temperature is unstable, the unstable seal number can be pressed at the channel number, so at this time, the original number should be reset to ensure that it can work normally.
After the temperature instability is solved, when the paper bag machine has a colorless signal, how to solve it?
No color signal cause:
1． Adjust photoelectric sensitivity;
2． The air pressure of the front drag roller cannot be too small, generally not lower than 0.3;
3． There is too much dust and dirt on the photoelectric head, which needs to be cleaned;
4． Heat-seal the knife, cool down to too low; (adjust the blade distance)
5． Setting the bag length does not match the actual bag length; (modify the bag length parameters)
6. The color-coded area is often too small; (not less than 1mm, not more than 3mm)

7. Incorrect polarity setting.
