Learn about the Multicolor industrial inkjet printing machine
Multicolor industrial inkjet printing machine is currently widely used in industry, the last article we mainly introduced the basic knowledge of multicolor industrial inkjet printing machine, but about multi-colormulticolor industrial inkjet printing machine we have to learn a lot of knowledge, today we will continue to understand the relevant knowledge of multicolor industrial inkjet printing machine.
Structural composition of multicolor industrial inkjet printing machine
The multicolor industrial inkjet printing machine mechanism is mainly composed of printing head bracket, vehicle guide rail, vehicle support guide rail, drive track, stepper motor and vehicle initial position sensor. When the printing operation is performed, the stepping motor runs to drive the transmission track to rotate. The printing head bracket loaded with the printing head will then reciprocates horizontally along the guide rail under the action of the transmission track, so as to complete the horizontal printing work.
How do multicolor industrial inkjet printing machines work
When the printer motherboard received the computer printing work, immediately through its decoding into various signal pulse, first control the paper feeder into the paper, in the ink jet printer paper channel has a paper sensor, it is controlled by time pulse signal, if there is no trigger within the specified time, then the motherboard judgment paper failure, continue to enter the next time, two consecutive paper failure will be feedback to the computer a printer lack of paper signal. If the sensor is successfully triggered within the set time, the motherboard will record this data, and then the step signal is accurately controlled by the grating disk sensor, and then the ink car where the print head is located is positioned according to the lateral grating sensor. At this time, the motherboard has obtained the X and Y axis data of the print head and paper, and then you can calculate the exact coordinates based on the X and Y axis data. When the print head goes to the coordinates with the printed data, the motherboard immediately gives a pulse signal to control the print head to spray ink droplets, which repeatedly forms a pattern on the paper.
Just talked about how multicolor industrial inkjet printing machines work overall, but now let's talk about how inkjet print heads work
Now the commonly used multicolor industrial inkjet printing machines are divided into hot foam type and micro-piezoelectric type according to the working principle.
Hot foaming type: it heats the ink instantly by heating the parts, causing the ink to instantly vaporize, and then uses the pressure generated by its vaporization expansion to spray the ink from the nozzle. When the ink shoots out, the bubble disappears, and the ink pressure in the printing head returns to the initial state. Because the ink acts as a coolant when spraying, so the hot foam nozzle must not lack the ink to continue to use, it is easy to burn down because the temperature is too high.
Micropiezoelectric: The key component of the micropiezoelectric printing head is the piezoelectric element, which controls the deformation of the piezoelectric element through the current signal to produce the injection of ink backlog, which can more accurately control the size and injection direction of ink droplets and ensure the accurate control of ink. Micropiezoelectric printing head is different from hot bubble printing head. Because the whole ink injection process is completed at room temperature and does not need heating, so in principle, micropiezoelectric printing head is more durable than hot bubble printing head, in fact, it is also the case.
Domestic current production of multicolor industrial inkjet printing machine technology has been very mature, there are many do good manufacturers, such as SHZPower is a professional multicolor industrial inkjet printing machine Chinese manufacturers, if you want to know more about multicolor industrial inkjet printing machine, want to find high quality multicolor industrial inkjet printing machine, welcome to send email query at any time.
