UV printers, whether they are tablet machines, roll machines, or plate roll integrated machines, use UV-LED optical curing technology, and the printing heads used are imported piezoelectric inkjet printing heads,
Among them, the printing head brands include Epson, Ricoh, Seiko, Kyocera, Toshiba, Konica, Sail, etc. The ink used is UV ink, and the printing head is installed in the printer's motion car (according to different color schemes, multiple nozzles can be installed in the printing car),
UV ink is supplied through the ink path system of the printer, and the printing cart is installed on the guide rail of the printer crossbeam. The cart is driven back and forth by a conveyor belt/maglev and servo motor, and the grating decoder installed on the crossbeam recognizes the cart's movement position on the X-axis
At this point, UV ink finally sprays out ink droplets through the nozzle of the printing head, which fall onto the printing medium. Thousands of ink droplets gather to form a pattern. At this time, the UV LED curing light installed on the car head quickly illuminates the printed image with ultraviolet light as the car moves
Shoot and solidify patterns. The curing principle is that there is a photoinitiator in UV ink that quickly solidifies through ultraviolet radiation. Due to the heat generated during UV LED curing, a water/air cooling device is installed to cool the UV LED lamp in a timely manner,
Thus ensuring the service life of UV LED lights.
