Floating ink cleaning device for inkjet printing machine

Abstract

The invention relates to a floating ink cleaning device for an inkjet printing machine, which is mainly used in intermittent inkjet printing machines. At present, there is no floating ink cleaning device for inkjet printing machines that can effectively solve the problem of mist-like ink floating around the nozzle. The invention includes a frame, a conveyor belt, a transmission roller, a nozzle frame and a cross beam. The transmission roller is installed on the frame, the conveyor belt is connected to the transmission roller, the cross beam is fixed on the frame, and the nozzle frame is movably connected to the cross beam. It is characterized by: it also includes a left suction mechanism with an ink filter on the left and used to absorb floating ink around the nozzles of the nozzle rack when the nozzle holder moves to the right, and an ink filter on the right. , and a right air suction mechanism for absorbing floating ink around the nozzles of the nozzle frame when the nozzle frame moves to the left; the left air suction mechanism and the right air suction mechanism are respectively fixed on the left and right sides of the nozzle frame. The invention can effectively improve the printing quality and effectively prevent mist-like ink from suspending around the nozzle.

Description

technical field [0001] The invention relates to a floating ink cleaning device of an ink-jet printing machine, which is mainly used in intermittent ink-jet printing machines, and is specially used for cleaning the floating ink distributed around the nozzles. Background technique [0002] During the working process of the inkjet printing machine, there will be a large amount of mist-like ink suspended around the nozzle, which not only affects the printing effect, but also when the mist-like floating ink condenses into ink droplets, it will fall onto the printing medium, thus affecting The quality of inkjet printing products, in addition, part of the mist ink suspended around the nozzle will adhere to the nozzle, which greatly affects the printing effect of the nozzle, especially in the case of high printing accuracy requirements. [0003] There is still no effective method to solve the problem that the inkjet printing machine produces a large amount of mist ink suspended arou...

Problems solved by technology

[0002] During the working process of the inkjet printing machine, there will be a large amount of mist-like ink suspended around the nozzle, which not only affects the printing effect, but also when the mist-like floating ink condenses into ink droplets, it will fall onto the printing medium, thus affecting The quality of inkjet printing products, in addition, part of the mist ink suspended around the nozzle will adhere to the nozzle, which greatly affects the printing effect of the nozzle, especially in the case of high printing accuracy requirements.

[0003] There is still no effective method to solve the problem that the inkjet printing machine produces a large amount of mist ink suspended around the nozzle during the working process. Usually, the method of cleaning the nozzle is mainly used to overcome the above defects, but when cleaning the nozzle It is necessary to stop the inkjet printing machine, which will affect the production, and when the nozzle needs to be cleaned, a large amount of ink has accumulated on the nozzle, which has already affected the printing quality, and it is difficult to achieve the purpose of real-time cleaning. For example, the public date is 2014 On March 26, 2005, in the Chinese patent whose publication number was CN103660578A, a nozzle cleaning mechanism of an inkjet printing device was disclosed, and on July 20, 2005, the Chinese patent whose publication number was CN1640672 disclosed A nozzle cleaning device for inkjet printers, both of which are technologies for cleaning nozzles

[0004] There are also a small number of other structures to solve the problem that a large amount of misty ink is suspended around the nozzle during the working process of the inkjet printing machine. As the publication date is January 19, 2005, the publication number is CN1568261. In the Chinese patent, disclosed A nozzle guard for an inkjet printhead capable of removing residue, the printhead having an array of nozzles, the nozzle guard having an array of apertures individually corresponding to the array of nozzles through which ink droplets are ejected to a print medium On the nozzle guard, a wiper blade removes dust and residual ink stuck to the outer surface of the nozzle guard. The outer surface has grooves that are individually paired with each aperture to prevent residues carried by the blade from clogging the apertures. Although the ink droplets are sprayed through the pores to reach the printing medium, the problem of a large amount of mist ink suspended around the nozzle can be solved to a certain extent, but the structure of the nozzle guard is complicated, and because the ink droplets are sprayed from the pores Only when it reaches the printing medium, it will affect the printing quality

[0005] To sum up, there is currently no floating ink cleaning device for inkjet printing machines that has a simple structure and reasonable design, can effectively improve printing quality, and can effectively solve the problem of foggy ink suspended around the nozzles, thereby reducing the cost of inkjet printing. Overall performance of the machine
