Description
Technical field
The utility model relates to carbon powder cartridge for laser printer, particularly laser printer electronics photographic means cartridge.
Background technology
Common Equipment for forming image comprises duplicating machine, laser printer, facsimile recorder, colour band printer and LED printer etc.
Wherein, laser printer has performance brilliance, characteristics of high efficiency, obtains flourish in current society.The principle of work of laser printer is that laser instrument carries out high frequency modulated with the information of computing machine output, converts character pattern to by data control system.The laser beam that is loaded with character information is through optical system, along photosensitive drums axis uniform speed scanning on photosensitive drums, thereby form and the corresponding electrostatic latent image of input information, and carbon dust is adsorbed on the drum by the electric charge on the photosensitive drums, fill the image of hiding.When photosensitive drums is rotated, the visual picture development is transferred on the paper, by heating and pressurizing image is immersed in the paper fiber then, and final curing is on paper.Be used to form the developing material of image---carbon dust, often be stored in the powder storehouse of cartridge.
The disclosed cartridge of domestic application for a patent for invention prospectus CN1175013A mainly is made of developing cell and cleaning unit, can rotate mutually between Unit two.Developing cell mainly comprises toner, puddle support, developer roll and showing board, and cleaning unit mainly comprises waste powder hopper, photosensitive drums, cleaner plate and charging roller.Axial end in photosensitive drums is provided with a grounding component.The ground path electric connection of this contact element and electrographic imaging device is used to adjust, keep the voltage levvl of photosensitive drums.Particularly, this ground connection to touch part be the complete circle cylinder that metal material is made.Under the user mode, this metal cylinder inserts the photosensitive drums centre by the posting on the cartridge sidewall, cooperates with the boss of the photosensitive drums other end, cartridge is positioned on the correspondence position of printer.This metal cylinder is coaxial with the correspondence position of boss, photosensitive drums itself and the above-mentioned printer of the photosensitive drums other end.
Above-mentioned contact element is owing to have circular cross section, and its column part that inserts the photosensitive drums center is subjected to the frictional influence of photosensitive drums, forms to lag behind the servo-actuated rotation that photosensitive drums is rotated; It is arranged in the column part of above-mentioned posting, requires should be in static contact condition between the two according to the best that is electrically connected, yet because the rotation that this friction causes, makes between contact element and the above-mentioned posting and also produce certain relative rotational slide.This has just proposed higher requirement to the circular precision and the antiwear characteristic of posting.For dealing with this situation, be between contact element and posting, to form interference fit now, but this is unfavorable for the maintenance of equipment with common means.As shown in Figure 1, 2, accepting to be provided with posting 4 on the sidewall of the relative cartridge of boss 1 with photosensitive drums power.This posting 4 roughly is annular, and its center is coaxial with photosensitive drums, and it can be integrally formed with cartridge, also can be dismountable separating component.In posting 4 centres circular hole is set, contact element 2 inserts the photosensitive drums centre by this circular hole.
The utility model content
The utility model provides a kind of carbon powder cartridge for laser printer, and the photosensitive drums ground connection of this cartridge is touched between part and the posting has relative fixed and stable cooperating, and dismantles easy.
The above-mentioned purpose carbon powder cartridge for laser printer comprises image generation unit and image developing transfer printing unit.
Image generation unit has a waste powder hopper, a photosensitive drums and a cleaning device at least.Waste powder hopper, photosensitive drums and cleaning device are installed on image and generate on the frame.
The image developing transfer printing unit has a toner and an image developing transfer device at least.Toner and image developing transfer device are installed on the image developing transfer printing frame.
Image generates frame and image developing transfer printing frame flexibly connects, and for example connects by a pair of coaxial pin.
Be provided with a ground connection at photosensitive drum shaft to an end and touch part 31, be provided with posting 5 in the respective side walls of cartridge.
These cartridge characteristics are that ground connection is touched part 31 and comprised right cylinder 313,312 and rectangle cap 311.Right cylinder 313,312 coaxial connections.Right cylinder 313 diameters equal photosensitive drums end center hole, less than right cylinder 312.Right cylinder 312 the other end overlap with the rectangle end face of rectangle cap 311.The arranged outside of posting 5 has positioning cap 32, shape and himself coupling.The face shaping of positioning cap 32 and the coupling of the locating slot on the mainframe box, the position is provided with the through hole 321 of shape and rectangle cap 311 couplings in the middle.Rectangle cap 311 meshes fully with through hole 321 under the installment state.
Cartridge of the present utility model, outward appearance is the posting of annulus and ground connection touches face of cylinder fit form between the part, be adjusted into tetragonal surface engagement form, eliminate ground connection that the photosensitive drums rotation brings and touched friction rotation between part and the posting, making both become pure static immobilization cooperates, therefore the mated condition touched between the part of posting and ground connection is stable, helps improving electrical contact performance, and its dismounting is facility very also.
