Description

Cartridge

Technical field

The utility model relates to the powder development agent supply arrangement of using electric charge figure electrograving technology, specifically is removably mounted on the carbon dust feed cassette in the duplicating machine.

Background technology

CN1207511A Chinese invention patent ublic specification of application discloses a kind of ink powder supplying box, which comprises at least following components: the storage area of an ink powder; The meal outlet of one discharging ink powder; The transport portion that ink powder in the box is carried to meal outlet; The mixing part that ink powder in the box is stirred; And transport portion and mixing part power drive receiving unit independently separately.

This ink powder supplying box has two power drive receiving units, when laying in duplicating machine, needs two receiving units are partly docked with power drive exactly.

The mixing part of this ink powder supplying box is assembled by a plurality of parts, need ask the multiple tracks processing and assembling.The mixing part is made of axle and blade, and blade is made of a rigid element and dress flexible portion thereon again, and flexible portion is tightly scraped the box wall powder is swept transport portion, and blade is parallel with axle.

Summary of the invention

The purpose of this utility model provides a kind of improved cartridge, and make it to have the driving receiving portion and be provided with rationally, the characteristics of being convenient to install, and processing technology is simple, and cost reduces.

Therefore, the utility model adopts following technical scheme: supporting one puddle support and a feeding worm screw between the end walls of the tubular box body that is used for the splendid attire carbon dust, one of them end wall also is provided with meal outlet, the wall of box body constitutes by comprising two different faces of cylinder of radius at least, and promptly its tubular section has the shape of approximate " 8 " word.The unique power intake of whole cartridge is an end that stretches out the outer worm screw of meal outlet, and closely there are a gear and puddle support gearing mesh in its other end, and puddle support obtains power by this to meshed gears.It is on the same periphery at center and continuous vertically that the puddler of puddle support is positioned at the shaft.

The structure of puddler can be designed to multiple shape, as is a straight-bar; Or be a curved bar, the axis of curved bar is a constant pitch helical; Also can be made of one section straight-bar and one section curved bar, wherein the axis of curved bar is the constant pitch helical.Puddler can be many, rotates the circumferentially uniform of the face of cylinder, place along it.The gear that is positioned on the worm screw can be a face gear, and it is identical also to can be helical gear oblique rotation direction with worm screw, and adopting helical gear advantage is that transmission is more steady, and noise is lower, simultaneously, plays the effect of feeding worm screw in the gear caliper zones.

Because adopt technique scheme, through being located at the gear set transmission of cartridge inside, cartridge has only a power intake that cooperates with duplicating machine to the driving force of puddle support by worm screw, and is simpler relatively than two power intakes when packing duplicating machine into.Adopt the rod-type puddle support to replace leaf structure, do not had scraping between blade and box body to rub, reduced the running resistance of puddle support, reduced noise simultaneously.If puddler is selected suitable bar number and is had certain pitch, then can partly play the effect that carbon dust is driven to meal outlet, promptly when finishing loose carbon dust function, also can assist worm screw to carry out carbon dust and carry.

Be described further below in conjunction with embodiment.

Embodiment

Referring to Fig. 1, two end wall 40a of tubular box body 5,40b is supporting puddle support 4 and worm screw 6, an end wall of box body 5 also is provided with a meal outlet 7, the right-hand member of worm screw 6 is a power intake 8, power intake 8 has rectangular cross section and stretches out in meal outlet 7, also be slidingly matched when having the salable meal outlet of capping 9 left ends of rectangular opening 7 with power intake 8, right part with cooperate with the duplicating machine power source, pack into behind the duplicating machine, capping 9 will move to right to opening meal outlet 7 by earlier relative power intake 8 under the effect of duplicating machine power source, drive worm screw 6 work then under the power source

effect.End cap

1,3 seals the bearing seat 42,41 of worm screw 6 and puddle support 4 respectively, prevents that carbon dust from leaking.End cap 2 is used to seal the powder filling port 43 of cartridge.

Referring to Fig. 2 and Fig. 3, it roughly is two section configurations that circle is tangent that the section that constitutes the cylindrical body of box body 5 has, and lays respectively at the circle centre position of two circles in conjunction with the axle of the visible worm screw in position of each

capping

1,2,3 among Fig. 1 and Fig. 3 and puddle support.Capping 9 is in the sealing state with meal outlet 7 jam-packs before cartridge uses.

Below stress outstanding feature of the present utility model, referring to Fig. 4, the end of worm screw 6 is unique power intake 8 of cartridge, and the other end has a coaxial spiral gear 22 identical with hands of worm, in-line gears 13 engagements of it and puddle support 4.Puddle support mainly is made of axle 18 and straight line puddler 14, curve puddler 17, supporting 19 and stiffener 15,16 etc., and perverse nail 11 is used for the carbon dust between loose gear 13 and box portion left end wall, and caltrop 20 is used for the carbon dust between loose supporting 19 and box portion right end wall.With regard to design concept, puddler 14,17 can be the shape that Fig. 4 shows, also can be a straight-bar, can also be a curved bar; The supporting 19 of this example is a discoid body, also can be the body of rod of two ends difference coupling shaft 18 and puddler end, and the version of similar stiffener 16 is arranged.Whole puddle support 4 is an integral piece, and worm screw 6 also is so, all adopts glass fibre to add acrylonitrile-butadiene-styrene once-forming.Because be subjected to the restriction of releasing process, puddle support 4 and worm screw 6 will be adopted special plug connector with connecting also of box body end wall bearing seat, therefore, there is plug connector to be subjected to mouth 10 and button bit 12 at axle 18 left ends, the other end also has plug connector to be subjected to mouth and button bit 21; The worm screw left end also has plug-in unit to be subjected to mouth 23 and button bit.

Referring to Fig. 5, gear 13 is positioned at the left end of axle 18, the extension of 24 axles 18 of plug connector and with the mating reaction of bearing seat 41, penetrate from bearing seat 41 left ends, the elastic hook 45 of its front end snaps in button bit 12 when putting in place, thereby form the support relation of axle 18 on end wall, capping 3 is covered in bearing seat 41 external port and is made it sealing.

Referring to Fig. 6, supporting 19 is positioned at axle 18 other ends, and the elastic hook 46 of plug connector 25 1 ends is stuck in the button bit 21, and the other end has one to be subjected to mouthful and to have button bit, another plug connector 26 to cooperate with it and be through in the axis hole on the end wall.

Can be clear that the connecting relation between

plug connector

26 and 25 among Fig. 7, leak from box body for preventing carbon dust, be that the two sides of bearing seat is provided with O-

ring seal

27,28 at the box body axis hole.

Referring to Fig. 8, the left end of worm screw 6 is a spiral gear 22, tooth oblique with worm screw in the same way, plug connector 30 elastic hooks 49 ends from worm screw be subjected to mouthful penetrate and be stuck in the button bit, oneself be subjected to mouthful accept another plug connector 29, thereby make in the ring groove 31 of bearing saddle bore between two plug connectors on the box body end wall.
