Abstract
The utility model discloses a carbon powder box which comprises a powder bin, a magnetic roll, a magnetic sealing part and an elastic sealing part, wherein the powder bin is used for containing magnetic carbon powder; the magnetic roll is used for bearing the magnetic carbon and is supported between two longitudinal side walls of the powder bin rotatably; the magnetic sealing part is arranged at the end part of the magnetic roll and is in clearance fit with the peripheral surface of the magnetic roll; and the elastic sealing part which is contacted with the peripheral surface of the magnetic roll is arranged on the surface of the magnetic sealing part, close to the magnetic roll, and the elastic sealing part is fixedly connected with the magnetic sealing part. The carbon powder box has the benefits that: as no clearance exits between the sealing structure of the end part of the magnetic roll and the peripheral surface of the magnetic roll, when the carbon powder box installed in a printer is impacted by the outside, magnetic powder gathered at two ends of the magnetic roll are blocked by a felt and can not cross the clearance to the outside of the carbon powder box, therefore, pollution is avoided.
Description
Technical field
The utility model relates to a kind of cartridge, relates in particular to the magnetic roll end hermetically-sealed construction of cartridge.
Background technology
Laser printer is one of present most widely used computing machine output peripheral equipment, and it utilizes the physics, the principles of chemistry of light, electricity, heat by interaction output character or image.Basic process can be divided into seven steps such as charging, exposure, development, transfer printing, photographic fixing, the electricity that cleans, disappears.At first, photosensitive drum surface is charged equably by charging roller.Laser scanner is launched the laser through ovennodulation that contains image information to photosensitive drums, forms and the electrostatic latent image for the treatment of that duplicating image is corresponding at photosensitive drum surface.Then, from the carbon dust of developer roll then be adsorbed on and make electrostatic latent image convert visual image on the photosensitive drum surface.Along with the rotation of photosensitive drums and the positive voltage effect that the recording medium back sides such as paper is applied through transfer roll, the electronegative carbon dust that has formed visual image at photosensitive drum surface is produced attractive force, and the visual image that is formed by carbon dust promptly is transferred on the recording medium such as paper.Enter the photographic fixing assembly that warm-up mill and backer roll form subsequently, carbon powder particles fuses in the fiber of recording medium under the effect of heat and pressure, so the visual image full solidification that carbon dust forms is on recording medium.So basic imaging action has just been finished.
In the disclosed developing device structure of Chinese invention patent CN1119714C, usually adopt developer roll (magnetic roller) absorption to be arranged in the magnetic carbon dust in powder storehouse with magnetic, magnetic carbon dust on the magnetic roller then be adsorbed on and make electrostatic latent image convert visual image on the photosensitive drum surface then, for preventing that carbon dust from leaking, adopt the circumferencial direction at the two ends of magnetic seal spare left magnetic roller to seal, the gap of magnetic seal spare and magnetic roller circumferential surface is usually between 0.5-1mm.Under most of working environment condition, the effect at the sealing magnetic roller two ends of above-mentioned magnetic seal spare is effective, otherness increase along with user's working environment, use printer as the user at environment such as the means of transport that moves such as aircraft, automobile, trains, the number of times that causes printer to be subjected to extraneous impact increases, after being installed in cartridge in the printer and being subjected to foreign impacts, the carbon dust of assembling the left magnetic roller two ends will be crossed the gap and appear at the cartridge outside surface, forms and pollutes.
The utility model content
The purpose of this utility model is the defective at prior art, and a kind of cartridge with excellent sealing effect is provided.
For solving the problems of the technologies described above, the utility model has adopted following technical scheme: design a kind of cartridge, comprising: the powder storehouse that holds the magnetic carbon dust; Be used to carry the magnetic roller of magnetic carbon dust, rotatably be supported between vertical two side in described powder storehouse; Be distributed in the magnetic seal spare of described magnetic roll end, described magnetic seal spare is clearance fit relationship with described magnetic roller outer peripheral face; Wherein, the surface of the close magnetic roller of described magnetic seal spare is provided with the elastic sealing element that contacts with described magnetic roller outer peripheral face, and this elastic sealing element is fixedly connected on described magnetic seal spare.
Preferably, described elastic sealing element adopts felt to make.
Preferably, described end seal structure is curved, and its outer peripheral face along the magnetic roller extends.
The beneficial effects of the utility model are: owing to do not have the gap between magnetic roll end hermetically-sealed construction of the present utility model and the magnetic roller outer peripheral face, after cartridge in being installed in printer is subjected to foreign impacts, the carbon dust of assembling the left magnetic roller two ends is stopped by felt, can not cross the gap and appear at the cartridge outside, thereby avoid pollution.
Description of drawings
Fig. 1 is the structural representation of a kind of cartridge of the present utility model.
Fig. 2 is the cross-sectional view of cartridge shown in Fig. 1, and slice location is magnetic roll end hermetically-sealed construction place.
Fig. 3 is the structural representation of cartridge shown in Figure 1 after having hidden the magnetic roller.
Embodiment
Referring to Fig. 1, a kind of cartridge 1 of the present utility model comprised the powder storehouse 2 that holds the magnetic carbon dust and has been used to carry the magnetic roller 3 of magnetic carbon dust, and magnetic roller 3 is arranged on outlet 4 places in powder storehouse 2, and between the rotatable vertical two side that is supported on powder storehouse 2.The two ends of described magnetic roller 3 are respectively equipped with the end seal structure 5 that is fixedly connected on 2 frameworks of powder storehouse, and described end seal structure 5 is curved, and its outer peripheral face along magnetic roller 3 extends.Wherein each end seal structure 5 has comprised a magnetic seal spare 51 and an elastic sealing element 52, and this elastic sealing element 52 is fixedly connected on magnetic seal spare 51.Magnetic seal spare 51 is clearance fit relationship with magnetic roller 3 outer peripheral faces, and elastic sealing element 52 is arranged on the outer peripheral face of close magnetic roller 3 of magnetic seal spare 51, and elastic sealing element 52 contacts with the outer peripheral face of magnetic roller 3.In the present embodiment, elastic sealing element can adopt felt to make.
Owing to do not have the gap between magnetic roll end hermetically-sealed construction of the present utility model and the magnetic roller outer peripheral face, after cartridge in being installed in printer is subjected to foreign impacts, the carbon dust of assembling the left magnetic roller two ends is stopped by felt, can not cross the gap and appear at the cartridge outside, thereby avoid pollution.
Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from inventive concept of the present utility model; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
