Problems solved by technology

However, this solution also has some defects: on the one hand, when the inkjet head is not working properly and the cleaning time is not up, the abnormal inkjet head will continue to work, which will affect the printing quality.
Obviously, due to the particularity of the work of inkjet printers, this monitoring method cannot be directly applied to inkjet printers, so how to make timely and accurate judgments on the working status of inkjet heads, and timely processing according to the judgment results is of great importance. more technically difficult

Embodiment 1

[0034] As shown in Figure 1, the automatic monitoring method of the inkjet head of this printer is realized through the following process: A. In the process of printing the pattern, the printer prints out the pre-set strips simultaneously on the edge of the printing medium. B. The detection head synchronously collects the detection pattern information printed by the inkjet head on the edge of the printing medium; C. Combines the collected detection pattern information with the pre-stored standard pattern information For comparison, if the two are consistent, the printer will continue to print; if they are inconsistent, the printer will interrupt the printing operation, and move the inkjet head out of the printing area to clean the inkjet head. After the cleaning process is completed, move the inkjet head Go back to the printing area and perform the printing operation again.

[0035] The above-mentioned automatic cleaning process of the inkjet head and the mutual switching of t...

Embodiment 2

[0042] As shown in Figure 4, in this embodiment, in step C, the cleaning of the inkjet head is powered by compressed air, and the ink is forced to flow out of the inkjet head for a period of time to clean the inkjet head. Wait for a while after completion before moving the inkjet head back to the print area.

[0043] The interrupt unit 3c is connected to the inkjet head 4 through the cleaning device 5 . Since the inkjet head 4 is cleaned by flushing, in this embodiment, the interruption unit 3 c is connected to the cleaning device 5 , and the cleaning device 5 is connected to the inkjet head 4 through the inkjet control system 6 . When the inkjet head 4 stops printing operation, the ink control system 6 is controlled by the cleaning device 5 to flush the inkjet head 4 with ink.

Abstract

The invention relates to an automatic monitoring method and a device for an inkjet head of a printer. In this method, the collected detection pattern information is compared with the pre-stored standard pattern information. If the two are consistent, the printer will continue to print; Clean the inkjet head. After the cleaning process is completed, move the inkjet head back to the printing area and restart the printing operation. Compared with the prior art, the cleaning of the inkjet head in the present invention is not carried out regularly according to the preset time, but decides whether to clean according to the real-time working state of the inkjet head. It has high degree of automation, obvious cleaning effect and good working stability. It can monitor the working status of the inkjet head in real time, and clean the inkjet head in time according to the monitoring results. The data processing volume is small and the processing speed is fast. features.

Description

technical field [0001] The invention relates to the field of inkjet printers, in particular to an automatic monitoring method and device for an inkjet head of a printer. Background technique [0002] Inkjet printers spray ink droplets of various colors onto the printing medium through the nozzles to form printing patterns. Because it uses ink, it is easy to dry, condense, and agglomerate on the nozzle, so that the ink cannot be ejected from the nozzle smoothly, thereby seriously affecting the printing quality. In addition, because the ink contains a small amount of impurities, air bubbles, etc., it may cause clogging or lack of ink to the nozzles of the nozzles when it is used continuously for a long time; Offset, fogging, or even failure to jet due to lack of ink or clogged nozzles. [0003] In order to meet the high-quality printing requirements, people have conducted long-term explorations and proposed various solutions for the characteristics of printers using various ...
