Embodiment 1

[0031] The present invention provides an automatic cleaning equipment for multi-station nozzles, which includes an air compressor 10 arranged at the end of the equipment frame 1, and a pressure reservoir is arranged on the equipment frame 1 on the right side of the air compressor 10 from left to right. Liquid tank 5, a row of waste ink stations, a cleaning liquid circulation cleaning station and an ultrasonic automatic cleaning station.

[0032] The waste ink discharge station is provided with a waste liquid tank 13, and the cleaning liquid circulation cleaning station is provided with a circulation cleaning recovery tank 7, and the ink tube connects the pressure liquid storage tank 5 to the ink inlet of the nozzle 2, The ink outlet of the nozzle 2 is aligned with the opening on the upper end of the recycling cleaning tank 7, and a precision pressure regulating valve 8 is arranged on the connecting ink pipe, and a liquid level sensor 9 is arranged inside the pressure storage ta...

Embodiment 2

[0039] The present invention also provides a cleaning method for multi-station nozzle automatic cleaning equipment, which is divided into the following steps:

[0040] 1) The waste ink discharge station is used to drain away the waste ink and waste residue inside the nozzle 2, clean the nozzle 2, and connect the cleaning liquid from the ink inlet of the nozzle 2 during use , discharged from the ink outlet and the nozzle 2, thereby taking away the waste ink in the nozzle 2, completing the first step of preliminary cleaning, and the cleaned waste ink will be directly discharged through the waste liquid tank 13 below ;

[0041] 2) The cleaning liquid circulation cleaning station is used to carry out long-term automatic cleaning of the clean cleaning liquid inside the nozzle 2 through a certain pressure (generally 10kPa-100kPa, adjusted according to the maximum pressure range of the different nozzles). Circular flushing is used to remove the internal impurities of the nozzle 2. W...

Abstract

The invention provides multistation spray nozzle automatic cleaning equipment and a cleaning method. According to the equipment, an air compressor is mounted at one end of an equipment framework. A pressure reservoir, a waste ink discharging station, a cleaning fluid circulating cleaning station and an ultrasonic automatic cleaning station are formed in and arranged on the equipment framework. A waste liquid groove is formed in the waste ink discharging station. A circulating cleaning recovery groove is formed in the cleaning fluid circulating cleaning station. An ink pipe is connected with anink inlet enabling ink to enter a spray nozzle from the pressure reservoir. An ink outlet of the spray nozzle is aligned with an opening in the upper end of the circulating cleaning recovery groove.A precise regulating valve is arranged on the connecting ink pipe. A liquid level sensor is arranged inside the pressure reservoir. According to the cleaning equipment and the cleaning method providedby the invention, the three stations for waste ink clearing, circulating cleaning and ultrasonic cleaning are arranged, assembly line type operation is adopted, moving among the stations is achievedthrough transverse moving slide rails and limit switches, the spray nozzle does not need to be dismounted or mounted again, operation is quite convenient and fast, and the cleaning efficiency is quitehigh.

Description

technical field [0001] The invention relates to the technical field of piezoelectric nozzle cleaning, in particular to a multi-station nozzle automatic cleaning device and a cleaning method. Background technique [0002] Piezoelectric jet printing is to press out the ink in the nozzle by applying voltage to the piezoelectric crystal, causing it to undergo high-speed and slight deformation. When the piezoelectric crystal is subjected to an external pulse voltage, the piezoelectric crystal is deformed, thereby reducing the volume of the ink chamber of the nozzle. In this way, a drop of ink is ejected from the nozzle. The piezo crystal then returns to its original shape and new ink enters the nozzle due to surface tension. By arranging a large number of nozzles side by side, the ideal print width and resolution can be achieved. [0003] Piezoelectric nozzles are generally used for high-speed inkjet printing. The nozzles have a large number of nozzles (more than 100 to 2,000)...
