Five ways to clean the nozzle of a leather digital printing machine

The rear compartment where the print head nozzle of the digital printing machine is located also includes the nozzle drive circuit board, so it is necessary to protect the drive circuit board and wrap the rear half of the compartment with the usual plastic wrap. There are several ways to clean the nozzles of printer nozzles: the first method: soaking method. Scope of application: less obstruction. Essential tools: 95% alcohol, a clean beaker and a metal container with a flat bottom. Prepare a small flat plate, put the nozzle flat in the plate, and then pour the special cleaning liquid for leather digital printing machine into the plate, and the depth shall be based on the partial immersion of the nozzle. Be careful not to splash water on the cable plug and drive circuit board. The first soaking time is about 1 to 4 hours. The second method: nozzle injection pressure flushing, applicable scope: the obstruction is more serious. Essential tools: 95% alcohol, a clean cup, a disposable syringe, and a disposable infusion set. Working principle: Use the pressure generated by the siphon action of the syringe to inject alcohol, an organic solvent, into the print head, so as to achieve the function of cleaning the dried ink head. Use a plastic tube of a disposable infusion set, one end is inserted into the 5ml syringe, the other end is inserted into the nozzle ink hole of the nozzle of the digital leather printing machine that needs to be flushed, press the distilled water in the syringe into the nozzle, and pay attention to the pressure not too much. Large, so as not to damage the waterproof isolation glue inside the nozzle. This process needs to be repeated many times until you see a thin water column spraying out from each ink outlet. In this way, the clogged nozzle is cleaned and dredged. The third method: distilled water cleaning method: scope of application: severe obstruction. Essential tools: a decoded empty ink cartridge, a disposable syringe and a bottle of medical distilled water (purified water can also be substituted). Working principle: It is similar to the working principle of the pressure cleaning method, so I don't need to go into details here. Solution: First prepare a decoded empty ink cartridge, a disposable syringe and a bottle of medical distilled water, and use the pressure generated by the siphon effect of the syringe to inhale the distilled water into the digital leather printing machine ink cartridge through the vent of the ink cartridge After a while, suck up the injected distilled water with a syringe, so that the remaining ink in the ink cartridge of the leather digital printing machine can be cleaned up repeatedly. The fourth method: ultrasonic cleaning method, the scope of application: the most severe obstruction Working principle: use the ultrasonic cleaning machine to generate strong ultrasonic waves, vibrate the water molecules violently, shake the small dry ink particles and dissolve them in water to achieve cleaning the goal of. Solution: Gently put the inkjet print head of the digital leather printing machine into the washing machine, add pure water or special print head cleaning fluid, and the pure water or special print head cleaning fluid should just cover the stainless steel rim of the print head (note Do not let the pcb board come into contact with pure water or special cleaning fluid), and it can be cleaned quickly after 10 to 15 hours of startup. The advantage is that the cleaning effect is very ideal, the print head that has been blocked for many years can be cleaned, and the operation is very simple; the disadvantage is that the maintenance cost is relatively high and the price is relatively expensive. Under normal circumstances, ultrasonic cleaners can be found in hospitals, spectacle shops or special mobile phone repair points, and in some places it is free, and ultrasonic humidifiers can also be used to modify them. It’s worth noting that you must use pure water or special print head cleaning fluid to use the cleaning fluid. You can’t use the cleaning fluid from hospitals, eyeglass stores or mobile phone special repair points, because the cleaning fluid in eyeglass stores generally contains more impurities. , The cleaning fluid of mobile phone special repair points is generally a strong organic solvent, and frequent use will cause fatal damage to the nozzle of the digital leather printing machine that is difficult to repair. The fifth method: If the nozzle has not been cleaned and dredged during the operation, it is basically a hard blockage. At this time, it is recommended to contact the leather digital printing machine manufacturer and use the manufacturer’s equipment for cleaning.
