Embodiment Construction

[0013] The technical solution of the present invention will be described in further detail below through specific embodiments and accompanying drawings.

[0014] figure 1 A structural schematic diagram of an embodiment of the nozzle cleaning device provided by the present invention. like figure 1 As shown, the device may specifically include: an air compressor 11, a first container 12, a second container 13, a first fluid switch 14 and a negative pressure generating device 15, wherein:

[0015] The exhaust port of the air compressor 11 is connected with the air inlet of the first container 12, and is used for inputting the compressed air with constant pressure generated into the first container 12, so that the cleaning liquid in the first container 12 is transferred from the first container 12 to the first container 12. A discharge port of the container 12 flows out;

[0016] The ink inlet port of shower head 16 is connected with the liquid discharge port of first container...

Abstract

The invention provides an ink jet head cleaning device which comprises an air compressor, a first container, a second container, a first fluid switch and a negative pressure generating device, wherein an exhaust hole of the air compressor is connected with an air inlet of the first container, the air compressor is used for producing compressed air with a constant pressure; an ink inlet of an ink jet head is connected with a liquid outlet of the first container, an ink outlet of the ink jet head is connected with the first fluid switch, a closed space is formed between the outer surface of a nozzle and the inner surface of the second container, when the negative pressure generating device is in an opening state and the first fluid switch is in a closed state, a cleaning solution in the first container outflows through the ink inlet of the ink jet head and the nozzle; when the negative pressure generating device works, a negative pressure is formed in the second container. According to the ink jet head cleaning device, a structure of the ink jet head is prevented from being damaged by an overlarge pressure, and tiny dust is prevented from being adsorbed on the nozzle of the ink jet head to block the nozzle.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a nozzle cleaning device. Background technique [0002] During the use of inkjet printing equipment, due to the long-term adsorption of tiny dust on the nozzle of the nozzle and the solidification of the attached ink generated during the inkjet process, the phenomenon of plugging or crooked needles often occurs after the nozzle is used for a period of time, which directly affects the printing. print quality. In order to restore the working state of the nozzle and improve the plugging and crooked needle phenomenon during the inkjet printing process of the nozzle, it is necessary to clean the nozzle. [0003] In the prior art, the cleaning process is mainly completed by manually controlling the injector to inject the cleaning liquid from the ink inlet of the nozzle. [0004] However, the existing technology has the following disadvantages: the nozzle of the nozzle is exposed to ...
