Abstract

The invention belongs to the technical field of industrial ink-jet printing, solves the technical problem of abnormal ink jet caused by the fact that the driving waveform of a spray head does not meetthe printing requirement in the prior art, and provides a spray head driving waveform adjusting method, a device, equipment and a storage medium. The method comprises the following steps: adjusting the pressurization rate and pulse duration of an initial driving waveform of a spray head to obtain a first driving waveform group; performing test printing by utilizing the driving waveforms of the first driving waveform group to obtain an alternative driving waveform meeting requirements; adjusting the fitting degree of the alternative driving waveform to obtain a second driving waveform group; and performing test printing by using the driving waveforms of the second driving waveform group to obtain a target driving waveform. The invention further discloses a device, equipment and a storage medium for executing the method. According to the spray head driving waveform adjusting method, the device, the equipment and the storage medium, the driving waveform of the spray head can be automatically calibrated during different types of ink printing, so that the ink-jet effect of the spray head is optimal, and the effect of printing images is ensured.

Description

technical field [0001] The invention relates to the technical field of industrial inkjet printing, and in particular to a method, device, equipment and storage medium for adjusting a driving waveform of a nozzle. Background technique [0002] Piezoelectric inkjet technology is to set many tiny piezoelectric ceramics near the nozzle position of the printer's nozzle. The two ends of the piezoelectric ceramic will bend and deform under the action of changing voltage, such as figure 1 , Figure 1a and Figure 1b As shown, the deformation of the piezoelectric ceramic will change with the change of the voltage across the piezoelectric ceramic, thus causing the volume of the ink-storing chamber of the nozzle to change. When the driving voltage is generated, the piezoelectric ceramic deforms, and the volume of the ink chamber shrinks, but at this time the nozzle is in the non-ejection position; the voltage decreases, the piezoelectric ceramic returns to its original shape, the vo...
