Printing nozzle device suitable for ink-jet printer

Abstract

The invention relates to the technical field of ink-jet printing, and discloses a printing nozzle device suitable for an ink-jet printer. The printing nozzle device comprises a nozzle shell, a high-voltage electrode deflection plate fixedly connected to the middle lower part of an inner cavity of the nozzle shell, and a fixed clamping block fixedly connected to the middle part of the inner cavityof the nozzle shell. According to the printing nozzle device suitable for the ink-jet printer provided by the invention, an ink collecting pipe, an S-shaped sliding pipe and an ink droplet charging device are matched, when accelerated downward ink drops obtained by the high-voltage electrode deflection plate reach the top end of the left side of the ink collecting pipe, power is generated to drivethe ink drops to slide along the ink collecting pipe and the S-shaped sliding pipe to be converted into centripetal force, and the ink drops slide into the ink cavity along the S-shaped sliding pipe,and ink flowing into the ink cavity again drives a conical driven plate to rotate, and then a cleaning plate is pushed to slide relative to the inner wall of the ink cavity, so that the ink is prevented from standing still, the uniformity of the ink concentration is kept, and the effect of printing characters by the ink-jet printer is improved.

Description

technical field [0001] The invention relates to the technical field of inkjet printing, in particular to a printing nozzle device suitable for an inkjet printer. Background technique [0002] Inkjet printing is through the vibration of the crystal rod to cause the ink jet to split and then form ink droplets, and then the ink droplets pass through the charging electrode with different electric charges, and the charged ink droplets enter the electric field and are deflected by the force of the electric field. Different, the deflection position is different, a dot matrix character or pattern is formed, and the uncharged ink drop enters the recovery tube. [0003] When the existing inkjet printers are printing, the printed characters need to carry out the electric field formed by the electrode to carry the corresponding electric quantity, and then shift to the corresponding paper surface by the electric field force, so as to form the corresponding digital symbol, but it is not c...

Problems solved by technology

[0004] The present invention provides a print nozzle device suitable for inkjet printers, which can maintain the uniformity of ink concentration, improve the effect of inkjet printers printing out fonts, and effectively drive the kinetic energy generated by ink to drive the guide block 55 to generate electric energy for power supply, effectively The advantages of using energy to improve the energy saving of inkjet printers, solve the problem that when the existing inkjet printers are printing, the characters that need to be printed carry out the electric field formed by the electrode with the corresponding electric quantity, and then offset by the electric field force to the corresponding paper surface to form the corresponding digital symbols, however, the uncharged ink drop moves vertically downward along the ink line, and then falls into the recovery tube. The existing ink in the recovery tube needs to be It is collected with the help of a power device, and then poured into the ink tank, which increases the production cost, and the ink in the existing ink tank is mixed with various raw materials in a certain proportion, so during use, the ink The ink solution on the bottom side of the inner cavity of the box will solidify on the side wall, resulting in uneven concentration of the ink solution, and then easily making the color depth (width) of the printed handwriting uneven, affecting the effect of printing the font, and the ink is printing When it comes out, it needs to be charged with external power, and it has a certain charge to push the ink drop to move, so it needs to consume more power, and it cannot effectively use the kinetic energy generated by the dripping ink, which increases its operating cost.
