Abstract
The utility model relates to a developing cartridge for a laser printer. The developing cartridge for the laser printer comprises a developing roll. Two axial ends of the developing roll are respectively supported on a framework. A sealing mat is respectively lined between two axial ends of the developing roll as well as two rims of the framework which is adjacent to the two axial ends of the developing roll. The developing roll is divided into a conceal part and an exposed part by a powder discharging blade and a sealing plate. The sealing plate is arranged on a part, close to the developing roll, of the framework. One edge of the sealing plate extends along the axial direction of the developing roll and is contacted with the outer surface of the developing roll to seal the developing roll. A paper guiding plate is fixed on the bottom of the framework. The part, close to the sealing plate, of the paper guiding plate is provided with a pressing bar for pressing the sealing plate onto the framework. According to the developing cartridge, the sealing plate is closely attached onto the framework of the developing box under the pressing of the pressing bar for pressing the paper guiding plate, so that the sealing plate can be prevented from dropping off, and the sealing performance of the developing roll can be maintained at a good state.
Description
Technical field
The utility model relates to the laser printer Delevoping cartridge, particularly includes the laser printer Delevoping cartridge of developer roll, powder feeding roller and lateral paper guide.
Background technology
With handle box 100 is that the imaging process of the laser printer of basic comprising core is, sees Fig. 1, is charged equably by charging roller 102 in photosensitive drums 101 surfaces.Laser scanner 103 contains image information and through the laser beam 104 of ovennodulation to photosensitive drums 101 external cylindrical surfaces emissions, cylindrical surface in photosensitive drums 101 after laser beam 104 irradiations forms the static charge distribution plan that its distribution has difference, that is the electrostatic latent image corresponding with image to be duplicated.Afterwards, the developer of carbon dust 106 that autography roller 105 transmits and so on is under the state of regulating bed thickness through powder delivery cutter 113 then be adsorbed on the cylindrical surface of photosensitive drums 101, after aforementioned electrostatic latent image covering, it is converted to can macroscopic visual image.Along with the rotation of photosensitive drums 101, the visual image that is formed at photosensitive drum surface by carbon dust 106 replaces to the position at transfer roll 107 places.Effect through the entrained transfer voltage of transfer roll 107, the carbon dust of visual image form is transferred on the surface of recording mediums 108 such as paper, with after after the carbon dust of the visual image form on 112 pairs of recording mediums 108 of warm-up mill 111 and backer roll carries out heating and pressurizing, carbon dust is penetrated in the fibrage of recording medium 108, and the visual image that carbon dust is formed for good and all solidifies on recording medium 108.Visual image on the aforementioned photosensitive drums 101 is after being transferred roller 107 transfer printings, residual carbon dust 109 attached to it is struck off to useless powder collecting bin by useless powder scraping blade 110, and photosensitive drums 101 surfaces return to after the corresponding electric equipment that disappears is eliminated static does not have the dustless stand-by state of electricity.So just finished a basic imaging workflow.This flow process is the result of cycle operation repeatedly, just can obtain the needed image of printing person.
For above-mentioned handle box 100, different manufacturers can produce the different product of integrated level in conjunction with the mentality of designing of oneself according to the function of handle box 100 each component parts, serviceable life etc.For example, parts such as the developer roll 105 of bearing developing function and powder delivery cutter 113 are integrated into independently Delevoping cartridge.This Delevoping cartridge has the storage developer and developer is transported to the effect on photosensitive drums 101 surfaces.101 of photosensitive drums are pre-configured in laser printer.Usually, this Delevoping cartridge has also set the lateral paper guide that paper is slided smoothly in its bottom.Lateral paper guide just is assemblied near the developer roll 105.Two members of powder delivery cutter 113 and diaphragm seal are divided into developer roll 105 towards the hidden part of powder-storage bin inner chamber with towards the exposed part of photosensitive drums 101.Diaphragm seal adopt usually bonding way be fixed on Delevoping cartridge adjoin developer roll 105 near, and in abutting connection with lateral paper guide.The bonding way of diaphragm seal often because used viscose glue progressively loses stickiness as time passes and causes that diaphragm seal comes off, causes developer roll 105 effectively not sealed.In addition, the axial two ends of developer roll 105 are supported on respectively in the dead eye of two edges of Delevoping cartridge framework.The axial two ends of developer roll 105 and with between two edges of the adjacent Delevoping cartridge framework in these two ends separately all liner seal felt is arranged, poor sealing to occur between the axial two ends that prevent developer roll 105 and two edges with the adjacent Delevoping cartridge framework in these two ends.Yet the phenomenon of coming unstuck and walking but often appears in the sealing felt when being subjected to developer roll 105 extruding, cause the sealing property decline at developer roll 105 axial two ends.
The utility model content
Cause the problem of developer roll sealing property decline at above-mentioned because of diaphragm seal comes off, the utility model purpose is to provide a kind of laser printer Delevoping cartridge.This Delevoping cartridge can effectively stop coming off of diaphragm seal, and then keeps the sealing property of developer roll in shape.
In order to reach above-mentioned utility model purpose, the laser printer Delevoping cartridge that the utility model adopts comprises the developer roll that developer is sent to photosensitive drum surface.The axial two ends of developer roll are supported on the framework respectively.At the axial two ends of developer roll and between with two edges of the adjacent framework in these two ends separately all liner seal felt is arranged.Powder delivery cutter and diaphragm seal are divided into hidden part and exposed part to developer roll.Diaphragm seal is positioned at the position of contiguous developer roll on the framework.An edge of diaphragm seal extending axially of developer roll and contacts with the sealing developer roll with the outside surface formation of developer roll.Lateral paper guide is fixed in the bottom of framework.The position of the contiguous diaphragm seal of lateral paper guide is provided with diaphragm seal is overlayed press strip on framework.
Aforementioned laser printer Delevoping cartridge, the position at the axial two ends of the contiguous developer roll of its lateral paper guide are provided with the seal felt corresponding to the axial two ends of developer roll are overlayed lock on framework respectively.
The utility model laser printer Delevoping cartridge, the problem that causes the developer roll sealing property to descend because of diaphragm seal comes off at existing Delevoping cartridge is provided with at the position of the contiguous diaphragm seal of lateral paper guide diaphragm seal is overlayed press strip on framework.Under this make, diaphragm seal is attached on the framework of Delevoping cartridge tightly because of the contention effect that is subjected to the lateral paper guide press strip, and then has stopped the phenomenon that existing Delevoping cartridge diaphragm seal comes off, thereby keeps the sealing property of developer roll in shape.In addition, by lock being set at the lateral paper guide two ends so that seal felt is overlayed make on framework, can also avoid come unstuck the walk phenomenon of existing Delevoping cartridge seal felt, thereby further keep the sealing property of developer roll in shape because of occurred by the developer roll extruding.
