Description

Technical Field

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

[0002] After the aerosol can is assembled, it needs to be coded on the outer surface of the can. The inkjet printer is a device that is controlled by software and uses a non-contact method to mark the product. It generally refers to continuous inkjet technology.

[0003] At present, most of the inkjet coding devices are in use. Under the pressure of the ink supply pump, the ink passes from the ink tank through the ink pipe, adjusts the pressure and viscosity, and enters the spray gun. As the pressure continues, the ink is ejected from the nozzle. Every time the ink is ejected from the nozzle, there will be residual ink adhering to the inner wall of the nozzle. If the ink is flushed before it dries, the ink adhering to the inner wall of the nozzle can be easily cleaned. However, since the structure of the nozzle needs to be cleaned, the screws must be disassembled and installed, and the nozzle shell must be opened to clean the inside of the nozzle. The operation is more troublesome. Therefore, it is impossible to flush the nozzle in time and quickly after each coding is completed. This leads to the problem of easy clogging of the nozzle. Therefore, it is necessary to design a coding device that can quickly and at any time flush the inner wall of the nozzle without disassembling the nozzle shell to solve the above problem.
