Abstract
The invention relates to a doctor blade device used for an inkjet printer. The doctor blade device comprises a body, wherein a plurality of convex stripes are arranged on one surface of the body. The ink scrapped by using the doctor blade device provided by the invention flows to the bottom of the doctor blade device along the extending direction of the convex stripes on the body, and can not stay on the top of the body, so that the ink is prevented from being stuck on inkjet pen point again in the process of scraping the ink residual on the inkjet pen point for the next time; and furthermore, the anti-bending strength of the body is reinforced due to the convex strips, and the ink splashing caused by the oscillation due to the deformation recovery can be alleviated.
Description
Technical field
The present invention relates to a kind of squeegee devices that is used for ink-jet printer.
Background technology
Squeegee devices is the significant components that ink-jet printer is kept the nib cleaning; Its function is the residual ink of striking off on the ink-jet nib, and ink is directed in the device of storing useless China ink, because mostly the material of general squeegee devices is the rubber material; Elasticity is fine; Therefore the recovery meeting flicks ink easily after distortion, and its hunting frequency and amplitude are all bigger, causes ink to splash easily and assembly arround can polluteing.
Summary of the invention
In view of this, the present invention provides a kind of squeegee devices, is used to keep ink-jet printer nib cleaning.
A kind of squeegee devices that is used for ink-jet printer comprises a body, and a plurality of strias are arranged on the one side of this body.
The ink that uses squeegee devices of the present invention to strike off can flow to its bottom along the bearing of trend of stria on its body; And can not stay on the top of body; Thereby prevent to be stained with on the ink-jet nib again in the process ink inside of striking off residual ink on the ink-jet nib next time; And stria has strengthened the bend resistance intensity of body, can alleviate because of recovering the problem that concussion that distortion produced causes ink to splash everywhere.

The following specific embodiment will combine above-mentioned accompanying drawing to further specify the present invention.
The specific embodiment
Please refer to Fig. 1 and 2; It has disclosed the squeegee devices 100 of an embodiment of the present invention; It comprises body 10; This body 10 is a rectangle elastic sheet, and its top 11 is used for contacting with ink-jet nib 200 and moving in ink-jet nib 200, thereby can strike off the residual ink 300 on the ink-jet nib 200.
This body 10 one sides are provided with a plurality of strias 20, on these a plurality of strias 20 are arranged on 10 of this bodies along certain orientation.In this embodiment, these a plurality of strias 20 evenly are arranged on the face that body 10 and nib 200 offset along the direction perpendicular to top 11.In other embodiments, these a plurality of strias 20 can be along the direction at 11 one-tenth certain angles of inclination of the direction that is parallel to top 11 or edge and top even or inhomogeneous being arranged on 10 of the bodies.These a plurality of strias 20 have strengthened the bend resistance intensity of body 10, the hunting range in the time of can reducing scraping blade 10 and disappeared by deformation extent and external force after the external force.In this embodiment, these a plurality of strias 20 are parallel to each other.In other embodiments, be equipped with this a plurality of strias 20 on these body 10 two sides.
The bottom of body 10 also has a pedestal 30, and pedestal 30 is used for being fixedly connected with a drive unit (figure does not show), and 10 motions of drive device drives body are so that body 10 strikes off residual ink 300 on the ink-jet nib 200.Body 10 adopts has the corrosion-resistant material of high flexible, in this embodiment, and rubber or the plastics of the material of body 10 for having high flexible.
Strike off in the process of residual ink 300 on the ink-jet nib 200 in squeegee devices 100; According to the Coanda effect in the hydrodynamics; Fluid changes original flow direction; Change into along with the mobile tendency of the body surface of protrusion; The ink 300 that body 10 strikes off can flow to its bottom along the bearing of trend of stria 20 on the body 10, and can not stay on the top 11 of body 10, thereby prevents to be stained with again on the ink-jet nib 200 in the process ink inside 300 of striking off residual ink 300 on the ink-jet nib 200 next time.
The ink 300 that uses squeegee devices 100 of the present invention to strike off can flow to its bottom along the bearing of trend of stria 20 on its body 10; And can not stay on the top 11 of body 10; Thereby prevent to be stained with again on the ink-jet nib 200 in the process ink inside 300 of striking off residual ink 300 on the ink-jet nib 200 next time; Stria 20 has strengthened the bend resistance intensity of body 10, can alleviate because of recovering the problem that concussion that distortion produced causes ink to splash everywhere.
Those skilled in the art will be appreciated that; Above embodiment only is to be used for explaining the present invention; And be not to be used as qualification of the present invention; As long as within connotation scope of the present invention, appropriate change that above embodiment did is all dropped within the scope that the present invention requires to protect with changing.
