Spray head, ink-jet printer and ink-jet printing method

Abstract

The invention relates to a spray head, an ink-jet printer and an ink-jet printing method. The spray head comprises a charging panel and a plurality of groups of deflection plates, wherein the chargingvoltage of the charging panel is a fixed value, and a first ink line channel for ink droplets to pass through is formed in the charging panel; each group of deflection plates comprises a positive plate and a negative plate, the positive plate and the negative plate are arranged oppositely, and a gap is formed between the positive plate and the negative plate and used for forming a second ink linechannel for the ink droplets to pass through; the second ink line channels of the multiple groups of deflection plates are communicated; the deflection plates are arranged adjacent to the charging panel; and the second ink line channels and the first ink line channel are communicated to form a movement channel for the ink droplets. The charging voltage of the charging panel is a fixed value, so that the electric charge quantity of all the single ink droplets passing through the charging panel is the same, in the ink-jet printing process, the charging panel can be always in a power-on state, the ink droplets are charged uninterruptedly, in the abovementioned way, the jet printing speed of the ink-jet printer can be not limited, and the service life of the charging panel can be prolonged.

Description

technical field [0001] The invention relates to the field of coding technology, in particular to a spray head, a coding machine and a coding method. Background technique [0002] The inkjet printer is a device that marks products in a non-contact manner, including structures such as nozzles, ink systems, electronic systems, and chassis. Among them, the nozzle prints high-quality characters in the form of dot matrix, which is the main component of printing information and can meet the special needs of different industries. The nozzle of the prior art splits the ink line through the ink chamber to form ink droplets. The ink droplets are charged with electricity through the charging plate, and the charged ink droplets enter between two opposite deflection plates, deflected under the action of the electric field force, and pass through the outlet. The ink port falls on the product, and the required logo is printed out with the movement of the product, and the uncharged ink drop...

AI Technical Summary

Problems solved by technology

[0003] The nozzles of traditional inkjet printers have the following defects: first, when the charging board charges the ink droplets, the falling interval of each drop of ink must be greater than or equal to the charging time for the charging board to charge the ink droplets to the maximum charging capacity, thus limiting The printing speed of the inkjet printer

Second, during the printing process, the charging board needs to continuously perform the process of "turning on → charging → closing" for different lengths of time, which will damage the working load and service life of the charging board
