Printer and sprayer cleaning device thereof

Abstract

The invention discloses a sprayer cleaning device including ink pads in one-to-one correspondence with sprayers and fitting with spray nozzles of the sprayers in a sealed manner, a buffer bottle used for enabling all ink pads to be communicated with each other, a diaphragm pump communicated with the buffer bottle, and a micro-metering valve arranged between the buffer bottle and the diaphragm pump and used for adjusting pressure. According to the invention, the added buffer bottle enables all the ink pads to be communicated with each other, so that pressure received by all the sprayers is generally the same. Therefore, problems of inconsistent dredging and cleaning of the sprayers due to different pressure are avoided and time and cost are saved effectively. Besides, pressure adjustment is also performed by using the micro-metering valve, so that sprayer damage due to too large or too small pressure is avoided; the service lifetime of the sprayers is prolonged; the cost is reduced; and the cleaning and dredging effects of the sprayers are guaranteed. The invention also discloses a printed including the above sprayer cleaning device.

Description

technical field [0001] The invention relates to the field of printer equipment, in particular to a nozzle cleaning device. In addition, the present invention also relates to a printer including the above nozzle cleaning device. Background technique [0002] With the popularization of commercial printers, more and more attention has been paid to the cleaning and dredging efficiency of printers. For printers, the nozzles used for inkjet may be blocked by solidified ink or impurities may appear in daily use. At this time, it is necessary to Clean and unclog the nozzle. [0003] like figure 1 As shown, the nozzle cleaning device in the prior art includes an ink pad 1 and a diaphragm pump 4 , the ink pad 1 and the diaphragm pump 4 are communicated through a pipeline, and each ink pad 1 is directly communicated with the diaphragm pump 4 individually. When the nozzle needs to be cleaned or dredged, stop the nozzle holder 7 at the moisturizing position (that is, keep the nozzle w...

AI Technical Summary

Problems solved by technology

[0004] However, in the prior art, since each ink pad 1 is individually connected to the diaphragm pump 4, and the pressure generated between different diaphragm pumps 4 is different, in the process of cleaning and dredging the nozzles, individual nozzles will not be cleaned. In order to make the printer work normally, cleaning and dredging will be carried out many times, which will waste a lot of time and directly or indirectly increase the working cost
