When you take off the sweater, and pull up the cover from the bed, you will hear the "crackling" sound, and you can also see the flashing sparks at night. Not only that, when your fingers touch the doorknob, faucet, chair back and other metal objects will have an electric shock, these are common electrostatic phenomena in life.Piezoelectric photo machineIs no exception, static electricity will interfere with the nozzle, resulting in drawing shielding, garbled code and other phenomena, serious will burn the nozzle. As we all know, connecting the ground wire is the work that must be done to operate the photo machine, and it is also an effective way to prevent static electricity and remove static electricity, so this work cannot be ignored.
As a photo machine user, in the daily use of the photo machine should pay attention to maintenance and maintenance work due to dry spring weather,The humidity in the air is very obvious, and even the humidity in some areas is lower than that20%The resulting electrostatic phenomenon is serious, and the direction of the ink droplets emitted before printing to the advertising material changes causing the phenomenon of paste head. If this phenomenon is not solved for a long time, the electrostatic voltage of the photo machine will reach6~10V, most likely to cause damage to the nozzle.
How is static electricity produced?Usually, when the piezoelectric photo machine is running at high speed, the trolley frame and the guide rail will have friction, and the high-speed operation is easy to cause a lot of static electricity.
Improvement method:
First of all, what needs to be done is to connect the ground wire to the photo machine, the ground wire is able to export the static electricity of the photo machine, the main methods:0.5m2The copper plate must be welded4mm2Copper wire buried in1.5Rice ground in wet soil below, and pour well salt water. Ground wire use the whole line, do not have a joint, good contact with the machine!
Secondly, it is necessary to maintain the humidity of the working environment of the photo machine, and the humidity around the photo machine is reached40~60%Relative humidity, so that the static electricity generated from the friction of the advertising material will also be transmitted from the air, will not affect the ink droplets on the nozzle, and avoid the indoor environment is too dry.
Some customers use static brushes to solve static electricity is also recommended, photo machine in the operation room for air exchange, pay attention to temperature and humidity changes!
Static electricity is not terrible, just look at how we prevent static electricity, reduce static electricity to a minimum, then hope that Audley users usually pay more attention!
