Problems solved by technology

[0012] On the other hand, in the technique of Patent Document 1, the washing liquid can be uniformly impregnated, but since a small amount of washing liquid is supplied to the wiping member, there is a disadvantage that it takes a long time for the wiping member to spread evenly until it becomes wet.
In addition, since the fog floats, there is also a problem of polluting the inside of the facility
[0013] In addition, in Patent Document 2, the uniformity of the cleaning liquid in the wiping member and the problem of liquid dripping caused by excessive cleaning liquid cannot be solved.
In addition, when wiping is performed without supplying the cleaning liquid, there is also a problem that the liquid-repellent film on the nozzle surface of the head is damaged.

Abstract

The dripping of washing liquid and the infiltration of washing liquid from a nozzle surface of a head when the nozzle surface is wiped is suppressed and discharge stability is improved. A wiping unit (100) includes a conveying portion (110) for conveying a wiping web (112), a washing liquid supplying portion (140) for supplying washing liquid to the wiping web, and a washing liquid collecting portion (150) for collecting washing liquid from the wiping web to which washing liquid has been supplied. After washing liquid is supplied to the wiping web, which is conveyed by the conveying portion, at washing liquid supplying portion, surplus washing liquid is collected from the wiping web at the washing liquid collecting portion. The wiping web from which washing liquid has been collected is wound on a pressure roller (122) and comes into press contact with the nozzle surface of the head, thereby wiping web wipes and cleans the nozzle surface.

Description

technical field [0001] The present invention relates to a nozzle surface cleaning device and an inkjet recording apparatus, and particularly relates to a head cleaning technique for wiping the nozzle surface of an inkjet head with a wiping member to which cleaning liquid is applied. Background technique [0002] In an inkjet recording device, when the nozzle surface (the surface on which the nozzle is formed) of the nozzle is contaminated, ejection failure occurs. Therefore, it is necessary to regularly clean the nozzle surface. [0003] As a method of cleaning the nozzle surface, a method of wiping the nozzle surface with a scraper, a method of wiping the nozzle surface with a web, and the like are conventionally known. [0004] Patent Document 1 discloses a technique in which, when spraying a cleaning liquid on a frictional contact sheet for wiping the nozzle surface of a droplet ejection head, a masking mechanism is used to delineate the spraying area of ​​the cleaning l...
