Description
Technical field
The utility model relates to the develop cartridge of usefulness of a kind of image processing system.
Background technology
Cartridge is that sub-image is developed the electrostatic latent image that forms on the photosensitive drum surface by the carbon dust electrostatic precipitation that the developer roll surface is carried.Existing a kind of cartridge comprises parts such as box body, carbon dust stirring apparatus, powder feeding roller, developer roll and powder delivery cutter, and developer roll is installed in the opening part of the front portion of box body, and its end is rotatably mounted by the two opposite side walls of box body.As shown in Figure 1, for prevent carbon dust in the developing chamber 11 from the both ends of developer roll (not shown) and the edge of the diapire 13 of box body 1 leak, be equipped with end seal 3 at the two ends of developer roll, below developer roll, also be provided with lower curtate seal membrane 4.Lower curtate seal membrane 4 can be PET sheet or chemglaze sheet, the one side is fixed on the outer rim place of the diapire 13 of box body by double faced adhesive tape, another side and developing roller surface Elastic Contact, and prevent that the carbon dust in the developing chamber 11 from coming out from the slot leakage of 13 of developer roll surface and box body 1 diapires.
The lower curtate seal membrane 4 of above-mentioned cartridge is the outer rim place that is fixed on the diapire 13 of box body 1 by double faced adhesive tape, all very easily be subjected to the influence of time, temperature and humidity because of the tension force of the ageing of double faced adhesive tape and lower curtate seal membrane 4, therefore lower curtate seal membrane 4 perk of coming unstuck as shown in Figure 2 easily, thereby cause carbon dusts in the developing chamber 11 to spill, pollute surrounding environment from the slit 41 of 13 of lower curtate seal membrane 4 and diapires.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of lower curtate seal membrane firm cartridge is installed.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is: cartridge, comprise: box body, inside are separated into powder storehouse and the developing chamber that is connected by meal outlet, being provided with along the opening of box body length direction extension away from powder storehouse one side of developing chamber; Developer roll can be rotated to support between two opposing sidewalls of box body; End seal is installed on the sidewall of box body and corresponding section, end developer roll, has and the contacted surface in contact in developer roll end; The lower curtate seal membrane is installed in the inboard outer rim place of box portion bottom wall along the length direction of box body, have one with developer roll contacted contact side in surface and an installation side relative with contact side; Fixture is installed in the inboard outer rim place of box portion bottom wall along the length direction of box body, and an end of its Width covers the installation side of lower curtate seal membrane, and the end of length direction is to the surface in contact of small part capped end portion packoff.
From above scheme as can be seen, fixture can be thoroughly be pressed together the bottom wall edge of lower curtate seal membrane installation side and box body, thereby prevents the edge perk of lower curtate seal membrane.
Scheme is that fixture is the strip sponge preferably, is fixed on the outer rim place, the outside of diapire after the other end turnover of its Width.Sponge is drawn materials conveniently, easily.
Better scheme be fixture by being adhesively fixed, easy for installation.
Another better scheme is the diapire outer rim place that fixture is connected to box body, and installing/dismounting is all convenient.

Fig. 3 is the structural representation of the utility model cartridge;
Fig. 4 is the axonometric drawing of the utility model cartridge;
Fig. 5 is that the utility model cartridge is not installed the structural representation under the developer roll state.
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
Embodiment
In conjunction with reference to figure 3 to Fig. 5, cartridge 100 comprises parts such as box body 1, carbon dust stirring apparatus 5, powder feeding roller 6, developer roll 2 and powder delivery cutter 7.
Box body 1 inside is separated into developing chamber 11 and powder storehouse 12, and the outside of developing chamber 11 wherein promptly is provided with an opening 111 away from powder storehouse 12 1 sides along the length direction of box body 1.Powder storehouse 12 is used to store the carbon dust of development usefulness and communicates with developing chamber 11 by meal outlet 121.
Carbon dust stirring apparatus 5 is positioned at powder storehouse 12, rotatably is supported on 14,15 of the two opposite side walls of box body 1, is used for the carbon dust in the stirring powder storehouse 12 and carries carbon dusts to developing chamber 11.
Powder feeding roller 6 is positioned at developing chamber 11, and meal outlet 121 places of closing on powder storehouse 12 are provided with, and are used for the carbon dust from powder storehouse 12 is flowed to developer roll 2.
Powder delivery cutter 7 is installed in the roof 16 of box body along the length direction of box body 1, can contact with the surface elasticity of developer roll 2, to adjust the carbon dust layer thickness on developer roll 2 surfaces.
Corresponding to the end positions place of developer roll 2, on the sidewall 14,15 of box body 1, be equipped with end seal 3, be used to prevent that the carbon dust in the developing chamber 11 from leaking from the both ends of developer roll 2.End seal 3 has and the contacted surface in contact 31 in the end of described developer roll 2.
Below developer roll 2,111 places are provided with lower curtate seal membrane 4 at developing chamber 11 openings.Lower curtate seal membrane 4 have one with developer roll 2 surperficial contacted contact sides 41 and an installation side 42 relative with contact side 41, be used to prevent that the carbon dust in the developing chamber 11 from leaking out from the slit of 13 of developer roll and box body 1 diapires.Lower curtate seal membrane 4 can be PET sheet or chemglaze sheet, is bonded in the inboard outer rim place of the diapire 13 of box body 1 along the length direction of box body 1 by installation side 42.
