Embodiment Construction

[0022] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Such as figure 1 As shown, a color printer nozzle includes an ink chamber 1, a driving device disposed in the ink chamber, and a nozzle 3 disposed at the bottom of the ink chamber.

[0023] The nozzle 3 includes a nozzle inlet 31 arranged in the ink chamber, a nozzle outlet 32 ​​arranged outside the ink chamber 1 , and a nozzle wall 33 connecting the nozzle inlet 31 and the nozzle outlet 32 ​​. The inner wall of the nozzle outlet 32 ​​is provided with a piezoelectric drive adjustment device for adjusting the aperture size of the nozzle outlet. The piezoelectric driving device includes a piezoelectric driving plate 321 arranged on the inner wall of the nozzle outlet, and an adjustment device electrically connected to the piezoelectric driving plate. The adjusting device adjusts the deformation of the piezoelectric driving plate by adjusting the voltage at...

Abstract

The invention relates to the technical field of printing, in particular to a spray head of a color printer. The spray head comprises an ink cavity, a drive device arranged in the ink cavity, and a spray nozzle arranged on the bottom of the ink cavity. The spray head is characterized in that the spray nozzle comprises a spray nozzle inlet arranged in the ink cavity, a spray nozzle outlet arranged below the outer part of the ink cavity, and a spray nozzle wall connecting the spray nozzle inlet with the spray nozzle outlet; the inner wall of the spray nozzle outlet is provided with a piezoelectric drive regulating device used for regulating the pore size of the spray nozzle outlet; and when electrified, the piezoelectric drive device generates deformation based on piezoelectric effect, so that the size of the pore size of the spray nozzle outlet is changed to adapt to printing ink with different particle sizes and viscosity specifications.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a color printer nozzle. Background technique [0002] When the printer is printing in color, the ink particles and viscosities of different colors or types are different. When using uniform nozzles to print ink with larger particles, it is easy to cause nozzle clogging. For example, the authorized announcement number is CN201089244Y, and the authorized announcement date is a Chinese invention patent on July 23, 2008, which discloses a combined nozzle structure of a digital inkjet printer. On the head of the inkjet printer, there are not only grayscale nozzles with high-precision and small dots, but also ordinary nozzles with low-precision and large dots. It overcomes the problem of nozzle clogging when a large number of nozzles with a single particle size are printed, and uses a combination of high-precision and low-precision nozzles to improve the best use of digital inkjet p...
