Abstract
The utility model discloses a cleaning scraper for removing residual developing agent on a photosensitive element. The cleaning scraper comprises a tool holder and a blade, wherein, an elastic element is arranged between the blade and tool holder; the blade is moveably arranged on the tool holder through the elastic element; a mounting groove accommodating the blade is formed on the tool holder; the elastic element is positioned at the bottom of the mounting groove; and part of the blade is mounted in the mounting groove, and the inner side edge of the blade elastically rests on the elastic element so as to realize the reciprocating movement of the blade in the mounting groove. When the cleaning scraper is mounted in a developing agent box or imaging equipment, a suitable contact pressure is always kept between the blade and the photosensitive element through adjusting the elastic element, so the problem that the blade is overturned due to overlarge contact pressure or the cleaning effect is poor due to insufficient contact pressure is avoided.
Description
Technical field
The utility model relates to a kind of cleaning doctor, more specifically, relates to a kind of cleaning doctor that is used to remove developer residual on the light activated element.
Background technology
The imaging device of electro photography like laser printer, is a kind of electrofax principle of utilizing, at least through overcharge, exposure, development, transfer printing, photographic fixing, process of cleaning, form the equipment that forms image on medium such as the paper at image.The required developer that forms images is provided by the developer box that removably is mounted to imaging device usually.
In charging process,, utilize and the surface of light activated element such as photosensitive drums is filled with predetermined electric charge equably like the corona discharge mode through charging device; At exposure process; Optionally make public in light activated element surface to filling even predetermined charge with; Because the light sensitive characteristic of light activated element; To be grounded cancellation by the electric charge of exposed areas, like this, after exposure light activated element surface form one corresponding to institute's desire form image by electrostatic latent image that CHARGE DISTRIBUTION characterized; At developing process, through developing apparatus, developer that is used to form visual image such as carbon dust, the electrostatic latent image district on the surface of light activated element is delivered in the effect of mating reaction power such as electric field force, and it is visual to make that above-mentioned electrostatic latent image obtains; In transfer process,,, transfer to image to the developer on the electrostatic latent image on light activated element surface and form on medium such as the paper like transfer roll through transfer device; At fixing, be secured in the developer of transferring on the image formation medium on the image formation medium through fixing device.At cleaning course, through cleaning device such as cleaning doctor, the developer of light activated element remained on surface is wiped off, in order to avoid make residual developer get into next imaging cycle, cause print defect.
The cleaning doctor of prior art all is fixed; Position relation between it and the light activated element is also fixed; Therefore; The effect of cleaning can be different because of physical dimension of cleaning doctor and light activated element, rigging error or the like factor, also might cause cleaning doctor to receive different pressure because of these errors and finally cause blade to overturn.In addition, knife rest is a metal material, and price comparison is expensive.
Figure 12 is the structure of a kind of cleaning doctor 10 of prior art, comprises metal knife rest 11 and plastic blade 12, and plastic blade 12 is fixed on the metal knife rest 11 through casting or bonding mode.Figure 13 is cleaning doctor and the position relation of light activated element 2 when work shown in Figure 12; Cleaning doctor 10 passes through screw retention on the housing 3 of developer box; And light activated element 2 is arranged on the housing 3 through register pin 21 rotationally; The position of light activated element 2 on housing 3 confirm, so the relative position between cleaning doctor 1 and the light activated element 2 fixes, and the plastic blade 12 of cleaning doctor 10 and the contact pressure between the light activated element 2 can not be regulated automatically.This cleaning doctor exists making the blade upset because of contact pressure is excessive or causing the not good enough problem of cleaning effect inadequately because of pressure of being caused by parts production error and rigging error.
The utility model content
The purpose of the utility model is to provide a kind of can regulate the cleaning doctor of contact pressure automatically, and the blade upset that makes because of contact pressure between blade and the light activated element is excessive that exists with the solution prior art perhaps causes the not good enough problem of cleaning effect because of pressure inadequately.
For realizing above-mentioned purpose; The utility model has adopted following technical scheme: a kind of cleaning doctor is provided; Comprise knife rest and blade, also be provided with flexible member between said blade and the knife rest, said blade is arranged on the said knife rest through said flexible member movably.
As further improvement to technique scheme; Has the mounting groove that holds said blade on the said knife rest; Said flexible member is positioned the bottom of said mounting groove; The part of said blade is positioned at said mounting groove, and the inner side edge of this blade flexibly is supported on the said flexible member, to realize the to-and-fro movement of blade in said mounting groove.
In one embodiment, the bottom of said mounting groove is formed with reference column, and said flexible member is the spring that is placed on the said reference column, and the length of said spring when not stressed is greater than the length of said reference column.In another kind of embodiment, said flexible member is the elastic caoutchouc post that is inserted in said pilot hole.In above-mentioned two kinds of embodiment, preferably, said flexible member has two at least.
In another embodiment, said flexible member is the profile of tooth elastic rubber strip that is fixed on said mounting groove bottom.
Preferably, the moulding of said knife rest for adopting plastic material to process through Shooting Technique.Because the plastic cement prices of raw and semifnished materials are compared the low and Shooting Technique production efficiency height of metal material price, so manufacturing cost is lower.
The beneficial effect of the utility model is: because blade is arranged on the knife rest through flexible member; Effect through flexible member; Blade can be realized moving back and forth with respect to knife rest, in the time of in cleaning doctor is installed in developer box or in the middle of the imaging device, through the adjusting of flexible member; Can remain suitable contact pressure between blade and the light activated element, can avoid making the blade upset perhaps cause the not good enough problem of cleaning effect inadequately because of contact pressure because of contact pressure is excessive.
