AI Technical Summary

Problems solved by technology

If impurities adhere to the nozzle surface, the ink droplets ejected from the nozzle will be affected, and fluctuations will occur in the direction of ink droplet ejection, making it difficult for ink droplets to land on the specified position on the recording medium, which will cause image quality deterioration

Embodiment Construction

[0042] Hereinafter, preferred embodiments of the present invention will be described based on the drawings.

[0043] [Overall Structure of Inkjet Recording Device]

[0044] First, the overall structure of the inkjet recording apparatus using the present invention will be described.

[0045] figure 1 It is a structural diagram showing the overall structure of an inkjet recording apparatus.

[0046] The inkjet recording apparatus 10 is a cylinder direct drawing type inkjet recording apparatus, which is on a recording medium 24 (for convenience, sometimes referred to as "paper") held on a cylinder (drawing drum 70) of the drawing section 16, From the inkjet heads 72M, 72K, 72C, 72Y, ink droplets of various colors are ejected to form the required color image. It is a drop-on-demand inkjet image forming device that uses two liquid reaction (agglutination) methods to eject ink droplets. Previously, a processing liquid (here, an agglutination processing liquid) was applied to the recording ...

Abstract

The invention provides a nozzle surface cleaning device and a liquid droplet ejecting apparatus that can perform maintenance under optimal conditions by performing the wet state when wiping using a cleaning solution in accordance with a plurality of conditions. The nozzle surface cleaning device is characterized by including an ink jet head having a nozzle surface with a nozzle disposed therein, a cleaning solution supplying unit that faces the nozzle surface and supplies a cleaning solution, a movement unit that moves one of the cleaning solution supplying unit and the head in longitudinal and traverse directions of the head, and a movement amount control unit that controls a movement amount of at least one of the cleaning solution supplying unit and the head. The movement amount control unit adjusts an amount of the cleaning solution adhering to the nozzle surface by moving them in the traverse direction by using the movement unit in accordance with an uncleanness state of the nozzle surface or an operation history of the head to relatively change a position at which the nozzle surface and the cleaning solution supplying unit face and overlap with each other.

Description

Technical field [0001] The present invention relates to a nozzle surface cleaning device and a droplet ejection device, and in particular, to a nozzle surface cleaning device and a droplet ejection device that can change the adhesion amount of cleaning liquid according to the dirty and working conditions of the nozzle. Background technique [0002] Various impurities such as ink residues and paper dust are attached to the nozzle surface and nozzle edge of the nozzle used in the inkjet recording device. If foreign matter adheres to the nozzle surface, the ink droplets ejected from the nozzle are affected, and the ink droplet ejection direction fluctuates, making it difficult to make the ink droplets fall to a predetermined position on the recording medium, which can cause deterioration of image quality . Therefore, it is configured to properly clean the nozzle surface in order to avoid abnormal discharge caused by the deposits on the nozzle surface. [0003] For example, Patent Do...
