Description

Technical Field

[0001] The utility model relates to the technical field of inkjet printers, in particular to a self-cleaning inkjet printer. Background Art

[0002] An inkjet printer is a device that uses software control and non-contact methods to mark products. It uses the principle of charged ink particles being deflected by a high-voltage electric field to print patterns, text and numbers on the surfaces of various objects. It is a high-tech product that integrates mechatronics. It can be used to print production date, batch number, barcode, trademark pattern, anti-counterfeiting mark and Chinese characters. It is a powerful equipment for implementing the health law and promoting packaging modernization. When the inkjet printer stops working, ink will remain on the nozzle of the inkjet printer. If it is not wiped off, it will easily affect the subsequent inkjet printing and contaminate the object to be coded. After searching, the Chinese patent with publication number CN219523394U discloses a nozzle self-cleaning inkjet printer, including a printer body, a nozzle roller, a nozzle assembly, a nozzle port and a cleaning mechanism; the number of nozzle rollers is two, and they are symmetrically distributed at the outer end of the printer body, the nozzle assembly is chiseled at the upper end of the printer body, and is located on the rear side of the nozzle roller, the nozzle port is arranged at the front end of the printer body, and is located between the two nozzle rollers, the nozzle port is connected to the nozzle assembly, the cleaning mechanism is installed at the upper end of the printer body, and is located on the upper side of the nozzle port, after the printer body finishes working , firstly, the squeezer is pressed by hand to squeeze the liquid storage bag by the squeezer, so that the detergent in the liquid storage bag enters the water outlet through the connecting frame and is sprayed out, so that the detergent enters and wets the sponge block, and while pressing the squeezer, the box body can be pulled to extend to the same level as the nozzle port, and then the squeezer is released and the pressing plate is pressed to move up and down along the fixed rod, and the first spring is used to make the pressing plate have an automatic rebound effect after being pressed down, and when the pressing plate moves up and down, it will drive the box body to rub against the end surface of the nozzle port, so that the sponge block can wipe the ink remaining on the nozzle in the nozzle port to achieve the cleaning effect, but the wiping process is relatively slow and cannot be wiped quickly, which is easy to affect the next inkjet printing, so that the inkjet printing efficiency is low. For this reason, a self-cleaning inkjet printer is designed, which is convenient for quickly completing wiping in the interval between two inkjet printings, ensuring the inkjet printing efficiency while completing the wiping, and further ensuring the inkjet printing effect.
