The voltage of the digital printing machine is too high during the working process, and its nozzle cannot withstand such high voltage, which will directly cause damage to the piezoelectric crystal to a certain extent, which will cause the phenomenon of nozzle burning. In the dry air season, the printing process of the digital printing machine is easy to generate and accumulate a large amount of static electricity. In severe cases, the nozzle will burn. At this time, it is recommended that everyone must make a ground wire for the digital printing machine, while keeping the indoor humidity between 35%-65%.
The positive and negative poles of the power supply of the digital printing machine are connected reversely: this is rare, but it is not ruled out that some operators will connect the positive and negative poles of the power supply in unfamiliar situations. Therefore, equipment operators must be familiar with the principle of the circuit, and do not easily plug or unplug the circuit without confirming it to avoid the operation of the positive and negative poles of the power supply.
The so-called static electricity is a kind of charge that is in a static state or that does not flow. When electric charge accumulates on an object or surface, it forms what we call "static electricity".
Digital printing machine is a wide-format printing equipment that relies on computer to control image output. Its core components are nozzles and various motherboard chips. In other words, digital printing machine is also a kind of precision equipment, so the internal circuit spacing of the machine is short. , The area is small, and the sensitivity voltage is between 0-200V, so it is easily affected by static electricity, causing printing abnormalities and other failures.
In order to avoid unnecessary losses, we must know how to scientifically and effectively prevent and eliminate static electricity in the workplace of the digital printing machine.
At present, in the working environment of digital printing machines, there are three ways to control and prevent static electricity:
1. Use a ground wire. Connecting wires is a simple way to control and prevent static electricity. Generally, digital printing machines are also equipped with corresponding grounding wires when they leave the factory. When actually operating the output, you must strictly follow the instructions of the digital printing machine's grounding wire plate to do the grounding work, and effectively lead the static electricity into the ground to prevent static electricity from flowing between the equipment parts.
2. Use electrostatic paint or electrostatic scavenger. When the digital printing machine is dry and hot and the output continues for a long time, the probability of static electricity is greatly increased. This requires firstly applying anti-static paint on the ground and wall in the digital printing machine workshop, and secondly adding static elimination around the equipment To eliminate static electricity, ion fans and ion air guns are commonly used.
3. Control indoor temperature and humidity. To effectively reduce or prevent static electricity, you must first control the room temperature and humidity in the working room of the digital printing machine. Generally speaking, the humidity is 35%-65% and the temperature is between 20℃-35℃. Static electricity on the equipment or printing materials It is more difficult to be transmitted, and the static electricity is smaller. Secondly, it is also necessary to pay attention to the ink selection of the digital printing machine. It is recommended to choose the original ink of the equipment. Influence, so the print screen is better.https://www.opmprinter.com/
