According to the carbon powder box, not only can the homogeneity of the power outlet amount of the carbon powder box be kept, but also residual test powder in the carbon powder box can be conveniently eliminated, the carbon powder box is simple and convenient in production operation, and high in labor production efficiency, and the carbon powder box is good in imaging quality.
Description
Technical field
The present invention relates to the main accessories of laser printer in a kind of office equipment, specifically the cartridge of modified laser printer.
Background technology
Usually, the major function piece of the cartridge of drum, powder integral type laser printer comprises: photoelectric conversion unit, charhing unit, developing cell.The main member of photoelectric conversion unit is photosensitive drums.Charhing unit mainly comprises the charging roller of positive charge grid-control formula corona charging roller or other form.Developing cell is made of the storage powder chamber, developing room and the developer roll that are used for the storage carbon dust.Developer roll and powder outlet cutter are chargeable so that carbon dust is electrically charged, thereby carbon dust can be transferred on photosensitive drums by the effect of electric field force, and the carbon dust layer thickness of developing roller surface deposition is controlled by the Elastic Contact of powder outlet cutter and developing roller surface.The visible powder outlet cutter of prior art generally comprises metal knife rest and plastic blade, the free end surface of plastic blade along the radial elastic of developer roll be pressed on the circumferential surface of developer roll, plane and the tangent formation angle of developing roller surface at free end place; And the plussage that free end exceeds contact point has the 2mm left and right, formation storage powder space between the circumferential surface of this part and developer roll; Importantly, the contact area of free end and developing roller surface is very little, is almost a kind of some contact.Due to powder outlet cutter prerequisite elasticity determined that it has larger hardness, cartridge its developing roller surface in long-term use procedure will be subject to the long-time friction of powder outlet cutter, cause developing roller surface progressively to produce cut, cause developing roller surface carbon dust deposition inhomogeneous, or white space without carbon dust absorption occurs, and then have a strong impact on printing effect.If but the pressure of powder outlet cutter reduces, contact fully not, can not well guarantee again to make the control powder effect of powder outlet cutter to cause developing roller surface carbon dust deposition thickness inhomogeneous, this carbon dust layer is transferred on photosensitive drums, can cause again image quality inconsistent.
In addition, in the toner cartridge of laser printer production run, after cartridge installs, need to carry out comprehensive quality printing test to each cartridge.Because can not tear powder storehouse strip of paper used for sealing, just need to add a small amount of test toner on developer roll, namely utilize a sharp mouth bottle that carbon dust is spread on magnetic developer roll, and will be evenly distributed on its surface.Need remaining powder removing work after test passes, otherwise remaining powder is in transportation, or the user can spill in using first between the cartridge seam of powder box, pollute packing and laser printer.The prior art solution has two kinds, and a kind of is to reduce to add test toner as far as possible, but test toner very little, just possibly can't satisfy the required carbon dust amount of printing test page, therefore, is difficult to hold on amount.Another kind of way is to adding the too many remaining powder of test toner repeatedly to print, and expectation exhausts remaining powder, and this processing is repeated multiple times, not only consumes paper, and labor productivity is low, and is exactly a kind of meaningless loss to cartridge itself.
For the problems referred to above, on January 3rd, 2007, Chinese utility model patent Granted publication CN 2854652Y discloses a kind of carbon powder cartridge for laser printer, just the position of powder outlet cutter is improved, it is positioned at powder outlet cutter integral body in developer roll outside surface contact position along downstream one side of developer roll powder feeding direction.Keep the free end of the powder outlet cutter of Elastic Contact to be circular arc on the cross section axial perpendicular to developer roll with developing roller surface.The virtual extension plane of powder outlet cutter blade and the face of developer roll depart from the developer roll axis, although this cartridge can reduce the scraping damage between powder outlet cutter and developer roll.But this structure needs the cartridge box body to redesign, and the cartridge box body on Chinese market is supporting ripe, so performance difficulty, and this cartridge does not also solve the processing problem of the remaining powder of test.
Summary of the invention
The objective of the invention is for the deficiencies in the prior art, a kind of cartridge of modified laser printer is provided; It not only can keep the homogeneity of cartridge powder outlet quantity; Can also conveniently remove the remaining powder of cartridge test, production operation is easy, and labor productivity is high; Use simultaneously the present invention, image quality is good.
For solving above-mentioned technical problem underlying, the cartridge of modified laser printer provided by the invention comprises box housing, developer roll, powder outlet cutter, photosensitive drums and charging roller; The box housing has the powder storehouse that can be used for holding carbon dust, is used for installing the drum frame of photosensitive drums; The box powder delivery chamber that holds developer roll is arranged between powder Hatch Opening and drum frame; It is characterized in that at the two ends of described box powder delivery cavity shell, respectively be reserved with respectively a duct of leading to the housing appearance in the described box powder delivery chamber, plugging device is all arranged on two ducts; Described powder outlet cutter is arranged on a side of developer roll; Metal knife rest and plastic blade are arranged on powder outlet cutter, the free end surface of plastic blade along the radial elastic of developer roll be pressed on the circumferential surface of developer roll; And free end exceeds the plussage that compresses a little 1.2mm.
Further, on described two ducts, plugging device is the adhesive sticker bar.
Further, on described two ducts, plugging device is soft plug.
Production period of the present invention, when carrying out comprehensive quality printing test, process means adds test toner routinely; After test passes, open the plugging device on two ducts, wherein a duct is air-breathing to the brigadier with the negative pressure device for inhaling powdery substances, another duct nature return-air; Rotate on magnetic roller of selenium drum and inhale once again, just remaining powder can be removed clean.Subsequently, then shutoff two ducts, get final product.
When the present invention uses, due to the plastic blade at the powder outlet cutter of cartridge, exceed than its free end of prior art and compress exceeding by amount and shorten a little.Then forming storage powder space and between the circumferential surface of developer roll reduces, pressure is because the shortening of plastic blade increases, like this, the pressure that increases forms with developer roll and contacts more uniformly, offset its metal knife rest and produced the possibility of distortion, add that the carbon dust that is adsorbed on developer roll reduces, the carbon dust of transfer printing correspondingly reduces, thereby avoids to a great extent the problem of print quality.Also overcome simultaneously the problem that the page powder consumption is large, page yields poorly.
The present invention's beneficial effect compared with the prior art is: after 1. production and assembly are completed, when carrying out comprehensive quality printing test, can conveniently remove the remaining powder of cartridge test, reduce the paper consumption, labor productivity is high.Through the practical operation check, can improve labor productivity more than 300%.2) by plastic blade free end length rationally is set, the carbon dust of transfer printing is correspondingly reduced, keep the homogeneity of cartridge powder outlet quantity; Also reduce significantly simultaneously the page powder consumption, reduced user's use cost.
