Description
Technical field
This utility model relates to toner cartridge technical field, is specifically related to the close-fitting structure of a kind of split toner cartridge.
Background technology
Toner cartridge is a critical component in laser printer, is topmost a kind of consumptive material.The core of laser printer
Technology is exactly electronic imaging technology, and parts associated therewith are exactly toner cartridge.Toner cartridge is mainly by photosensitive drum component and powder box group
Part forms.
Selenium drum of laser printer can be divided into integration toner cartridge and split toner cartridge by compound mode.Integration toner cartridge is photoconductor drum
The toner cartridge that (photosensitive drums), magnetic drum (developer roll) and powder box are integrated, this toner cartridge does not allows in design structure
User adds powdered ink, although part can also add powdered ink after technique improvement, but integration toner cartridge to commonly use the life-span shorter
OPC drum, when carbon dust is exhausted or opc photosensitive drum damages, whole toner cartridge must be scrapped.Split toner cartridge is powder box and drum (sense
Light drum assembly) separate, it is respectively individual components, the photosensitive drums of usual split toner cartridge uses preferable material (Se selenium or a-si pottery
Porcelain), this two kinds of photosensitive drums are the longest for service life, can print the life-span reaching 20,000, only powder box need to be consumed
Carbon dust is changed just, and the printing cost of such user the most greatly reduces, therefore split toner cartridge cost performance is higher.
Photosensitive drums is the cylinder that surface scribbles organic material, through charging roller (PCR) contact charging with electric charge；Powdered ink
Case assembly mainly includes powder cabin, puddler, powder outlet cutter, developer roll (or magnetic roller) and carbon dust, and wherein developer roll is responsible for adsorbing powder cabin
Interior carbon dust.After laser printer receives print data, the light beam that generating laser generates is swept in photosensitive drums, first exists
Photosensitive drum surface forms the latent image being made up of electric charge, when this latent image is through the developer roll of powder box, and the carbon dust on developer roll is just
Being adsorbed onto again in photosensitive drums, latent image is just converted to real image；Printing paper is admitted to subsequently, and the carbon dust of photosensitive drum surface turns
Print to be formed on printing paper image；Fixing through transfer roll again, image is just solidificated on printing paper, the printing stream of a page
Journey completes with regard to this.It can thus be seen that photosensitive drums and developer roll must keep distance (two cylinders of a reasonably stability
The most tangent), the carbon dust of developer roll just can be adsorbed in photosensitive drums, can ensure that print quality is normal.
The split toner cartridge of a kind of prior art, as illustrated in fig. 1 and 2, the conducting end of box body 1 is provided with first and determines column 11, U-shaped
Location bone 12, gear end is provided with second and determines column 13, driving gear 14.Described first determines column and second determines column correspondence respectively
Two draw-in grooves at drum two ends position, and prevent powder box from shifting up and down in drum；Recycling conducting end U-shaped location bone and drum
Frame coordinates, and gear end drives gear to coordinate with the motor driving head of printer, prevents powder box from retreating displacement in drum.
The use order of split toner cartridge is first to be entered by the column alignment drum draw-in groove oblique cutting of determining of powder box, and Gu Kacaochu positions up and down
Accuracy is higher, and then powder box is set level in drum, relies on U-shaped location bone etc. to withstand drum afterbody and makes powder box be installed to
, last drum puts into printer together with powder box, and when installation puts in place, the driving head of printer injects and drives gear, machine
Device is identified, and installs and just completes.It is fixed character owing to the conducting end U-shaped of powder box positions bone, and production technology determines
Drum has certain error with coordinating of powder box, and error is often more slightly larger than cartridge profile so that peace inside drum
Dress and replacing powder box, and drum drum imperial palace sky is yielding, therefore often occur that the location of conducting end U-shaped location bone is bad, tooth
Wheel end is owing to driving the combination of gear and printer driver head, and location preferably, causes powder box conducting end side to produce and retreats, beat
Print arises that bad phenomenon such as turning white.
