Fig. 2 is the structural representation under the toner supply port open mode of the utility model toner cartridge;
Fig. 3 is the structural representation of the agitating member of the utility model toner cartridge.
Below in conjunction with accompanying drawing embodiment of the present utility model is illustrated.
Embodiment
In conjunction with referring to Fig. 1 to Fig. 3, toner cartridge 100 comprises a housing 1.Housing 1 is long box shape basically, has the recurvate diapire from the lower end of antetheca 11 of an antetheca 11,12, lower wall of extending from the rear end of diapire 12 13, a cap 17 that is formed on the powder delivery cutter supporting walls 14 above the lower wall 13, the sidewall 15 that is formed on housing 1 length direction two ends and covering shell 1 upper shed backwards.Wherein, antetheca 11, diapire 12, lower wall 13, layer thickness adjusting scraping blade supporting walls 14 and sidewall 15 are integrally formed in together.On fore-and-aft direction, the inside of housing 1 is separated into two parts, and the front portion is divided into toner storage chamber 2, and the rear portion is divided into development chamber 3, is communicated with by toner supply port 4 between the two.
The toner storage is held coloured powder in the chamber 2, and is provided with agitating member 5.Agitating member 5 is used to stir toner and carries toners to development chamber 3 along on the rotatable two side 15 that is supported on housing 1 of the length direction in toner storage chamber 2.
Accommodate developer roll 6, powder feeding roller 7 and powder delivery cutter 8 in the development chamber 3.Rear portion in development chamber 3 also is provided with opening 31, in order to expose the part of developer roll 6.Powder feeding roller 7 and developer roll 6 all rotatably are supported on the two side 15 of housing 1, and wherein powder feeding roller 7 is set at the bottom of toner supply port 4 back, and developer roll 6 is located at the back of powder feeding roller 7, and setting contacts with powder feeding roller 7.Developer roll 6 is face-to-face with photosensitive drums after toner cartridge 100 is mounted to imaging device.Powder delivery cutter 8 is installed on the powder delivery cutter supporting walls 14, is positioned at developer roll 6 tops, its can with developer roll 6 Elastic Contact, in order to adjust the toner layer thickness on developer roll 6 surfaces.
Agitating member 5 comprises puddle support 51, agitating plate 52 and seal pad 53.Puddle support 51 has the turning axle 511 of a picture round bar, and this turning axle 511 can be rotated to support on the two side 15 of housing 1 of toner cartridge 100.Be provided with the gusset 512 that radially extends on the circumferential wall of turning axle 511, be used to install agitating plate 52, the length in the length of gusset 512 and toner storage chamber 2 is roughly suitable.Agitating plate 52 sticks on the gusset 512 along the length direction of puddle support 51, and extends along turning axle 512 outward radials.The length in the length of agitating plate 52 and toner storage chamber 2 is roughly suitable, and width should guarantee that its far-end 521 apart from puddle support 51 can store the inwall in chamber 2, especially diapire 12 sliding contacts with toner in agitating plate 52 rotary courses.Seal pad 53 is located at far-end 521 places of agitating plate 52, with agitating plate 52 whole formation.In particular, seal pad 53 is that the far-end 521 from agitating plate 52 extends out, and to the sense of rotation upstream side bending of agitating plate 52.Generally, angle is about 90 ± 10 degree between the extension line of seal pad 53 and agitating plate 52.Agitating plate 52 is made by materials such as PET resins with seal pad 53, all has certain elasticity and rigidity.
Can store the wall portion in chamber 2 with toner because of the far-end 521 of agitating plate 52, especially diapire 12 contacts, therefore the toner that sticks to the wall portion in toner storage chamber 2 and be deposited in the bottom in toner storage chamber can be stirred plate 52 and scrape and chip away, and filled powder and stirred, be delivered to development chamber 3, can effectively prevent residual toner in the toner storage chamber 2, avoid waste.
When the extension line of agitating plate 52 was positioned at the coboundary 41 of toner supply port 4, seal pad 53 can be with 4 sealings of toner supply port, and this moment, toner storage chamber 2 was separated fully with development chamber 3, can prevent that the toner in the toner storage chamber 2 from flowing into development chamber 3.Therefore when toner cartridge 100 dispatches from the factory, seal pad 53 can be threaded to this position, in toner cartridge 100 transportations, flow into development chamber 3, thereby avoid in toner cartridge 100 installation processes, occurring leaking powder to prevent toner.
Because the toner amount that needs in the development chamber 3 is a certain value, for different developer roll 6 and powder feeding roller 7, this numerical value is all different.For the chamber 3 that guarantees to develop can obtain the toner amount of needs, satisfy by adjusting agitating member 5 usually.52 numbers of agitating plate are many more, and the toner amount that rabbling mechanism 5 provides is just big, and is just high more for powder efficient.Therefore for obtaining good stirring and powder feeding effect, can agitating plate 52 quantity of the utility model toner cartridge 100 be defined as multi-disc according to toner amounts in the size in the toner amount of development chamber 3 needs, toner storage chamber 2 and the toner storage chamber 2, as be three, four, six or eight etc., multi-disc agitating plate 52 should evenly distribute on the circumferencial direction of puddle support 51.In the present embodiment, agitating plate 52 is four, is equipped with seal pad 53 at the far-end 521 of every agitating plate 52.
In conjunction with reference to figure 1 and Fig. 2, the course of work of agitating member 5 is described.Fig. 1 is the state of agitating member 5 when being in seal pad 53 sealing toner supply ports 4, and Fig. 3 is the state of agitating member 5 when being in agitating plate 52 powder feedings.After accepting from the driving force of imaging device, agitating member 5 begins to rotate along the arrow A direction, agitating plate 52 is in rotary course, the toner that toner can be stored in the chamber 2 fully stirs, and the promotion toner rotates together, when the extension line of agitating plate 52 is supplied with 4 lower limb 42 near toner, toner is conducted to development chamber 3 from toner supply port 42.Agitating member 5 continues rotation, the extension line that rotates to agitating plate 52 is positioned at toner when supplying with 4 coboundary 41, seal pad 53 can be with 4 sealings of toner supply port, and this moment, toner storage chamber 2 was separated fully with development chamber 3, can prevent that the toner in the toner storage chamber 2 from flowing into development chamber 3.After this, agitating member 5 rotates again, and toner supply port 4 can slowly be opened again, and operating for powder of next agitating plate 52 begins.
For obtaining good sealing property, the width of seal pad 53 should be supplied with 4 width to be slightly larger than toner, so that toner can be supplied with 4 sealings fully in transportation.But the width of seal pad 53 is also unsuitable excessive, otherwise can influence toner from of the supply of toner storage chamber 2 to development chamber 3, usually the free end of every seal pad 53 apart from the distance of its sense of rotation downstream adjacent seals plate 53 being good more than or equal to half of toner supply port 4 width.
For preventing in the whipping process that agitating plate 52 causes distortion because of the toner pressure that bears is excessive, be provided with a plurality of openings 522 on agitating plate 52.The quantity of opening 522 and big I are determined according to the toner amount in the toner storage chamber 2.
Technical conceive of the present utility model is not limited in the foregoing description, can also obtain many different concrete schemes according to design of the present utility model, can be fixed on the gusset of puddle support by alternate manners such as screws as agitating plate, the effect that obtains is identical, and change that these are small and equivalent transformation all should be included within the described scope of claim.
