Abstract
The purpose of this utility model is to provide a kind of new powder outlet cutter, by saving two ends pad, when reaching production assembling powder outlet cutter, optimizes production process, improves production efficiency.It is characterized in that：Including knife rest, described knife rest is fixed on toner cartridge, and described toner cartridge is fixed in printer, the two ends of described powder outlet cutter are extended with pawl, and powder outlet cutter is stuck on toner cartridge, and the groove coordinated again with pawl is set on described toner cartridge, the upper end of the pawl of described powder outlet cutter, is set by fixing hole.The edge of described powder outlet cutter is upturned, two parts formation right angle.The pawl of described powder outlet cutter often holds one.The beneficial effects of the utility model are：By the combination of pawl and toner cartridge, powder outlet cutter is stuck on toner cartridge, the fixing hole set on powder outlet cutter, after pawl does not work, or after groove variations on toner cartridge, powder outlet cutter can be fixed on toner cartridge by fixing hole and be continuing with.
Description
Technical field
The utility model belongs to printer technology field, particularly belongs to a kind of new powder outlet cutter.
Background technology
In printer, toner cartridge is a very important building block, and the structure of toner cartridge includes：1st, photosensitive drums：It is photosensitive
Drum is the heart of integral type cartridge, and all other component distribution plays each different in the surrounding of photosensitive drums centered on drum
Effect.In imaging process, photosensitive drums receive charging and laser irradiation, and formation electrostatic latent image in surface further forms visual
Carbon dust image.2nd, magnetic roller：I.e. developer roll, is that one of maximum part is influenceed on density of image.It is responsible for carbon dust out of powder cabin
Suction out, and make carbon dust powered with carbon dust friction.Due to the effect of developing bias in magnetic roller so that powered carbon dust " bounce ".3、
Doctor blade：Doctor blade is installed in below magnetic rod, is responsible for the carbon powder layer thickness adsorbed in control magnetic roller, and assist carbon dust friction belt
Electricity.4th, powder cabin：So-called powder cabin is exactly the warehouse for filling carbon dust, and having in the powder cabin of part has an agitator, to ensure carbon dust
Smoothly provide.5th, waste powder hopper：For filling the warehouse of useless powder.Can not be absolutely in the carbon dust image of photosensitive drum surface formation
It is transferred on print media, a part can be remained in photosensitive drum surface, before be imaged next time, cleaning doctor is scraped, received
Collection is in waste powder hopper.6th, cleaning doctor：The carbon dust remained after light drum epigraph transfer is experienced in responsible removing.7th, conductive bar：Some
There is a carbon dust induction rod powder cabin outlet of powder box, such as C3900A/C4092A, for sense carbon Lou amount number, work as carbon dust
Not enough, when there is space between magnetic roller and conductive bar, machine will show that carbon dust runs low, and TONERLOW signals occur.8、
Charging roller：It is responsible for photosensitive drum charging and electric discharge.
Powder outlet cutter (DB) also known as control sheet, are made up of metal pedestal and polyurethane piece.The effect of powder outlet cutter：
1st, make carbon powder particle powered with magnetic roller (MR) friction；
2nd, control magnetic roller set surface carbon powder layer thickness, makes carbon dust uniformly produce.
Points for attention in powder outlet cutter use：
1st, notice that its surface arbitrarily must not be handled with chemical solvent in production operation；
2nd, metal pedestal is tried one's best does not contact with water, prevents it from getting rusty；
3rd, not handy hand is contacted or its surface of oily pollution polyurethane piece in use；
4th, powder outlet cutter must not the adhesion of jagged or impurity, this can make occur vertical bar in print image；
If the aging of polyurethane piece, adhesion or deformation printing the 5, on powder outlet cutter are bad.
Laser printer is transported on print paper by the turning handle ink powder of magnetic roller, powder outlet cutter, photosensitive drums, charging roller, is
Control magnetic roller surface with one layer equably carbon dust and carried charge, it is necessary to install a powder outlet cutter being engaged, powder outlet cutter handle
Unnecessary ink powder is scraped in magnetic roller, it is gone out powder uniform.Existing laser printer powder outlet cutter is by knife rest and on knife rest
Silica gel blade is constituted, because silica gel blade is single thin slice, due to printer work frequently and reclaim utilization, silica gel blade with
Magnetic roller contact is often rubbed against, so one is the easy aging of silica gel blade, deformation, service life is short；Two be silica gel blade in high temperature
It is easily deformed under environment, is difficult to work in particular circumstances；Three be due to that can not normally be contacted with magnetic roller after silica gel blade aging
Work, causes leakage powder and triboelectric behavior low；Four be that the elastic dynamics of silica gel blade is relatively low, and control powder is uneven, and powder outlet quantity is uneven
It is even；Five be to influence the printing effect of toner cartridge.
When powder outlet cutter is produced and assembled, a pad need to be respectively assembled in two ends on powder outlet cutter, operation is time-consuming, wastes money
Source.
Utility model content
The purpose of this utility model is to provide a kind of new powder outlet cutter, by saving two ends pad, reaches that production is assembled
During powder knife, optimize production process, improve production efficiency.
A kind of new powder outlet cutter of the present utility model, it is characterised in that：Including knife rest, described knife rest is fixed on toner cartridge
On, described toner cartridge is fixed in printer, and the two ends of described powder outlet cutter are extended with pawl, and powder outlet cutter is stuck on toner cartridge, institute
The groove coordinated again with pawl is set on the toner cartridge stated, and the upper end of the pawl of described powder outlet cutter is set by fixing hole.
Further, the edge of described powder outlet cutter is upturned, two parts formation right angle.
Further, the pawl of described powder outlet cutter often holds one.
The beneficial effects of the utility model are：
By the combination of pawl and toner cartridge, powder outlet cutter is stuck on toner cartridge, the fixing hole set on powder outlet cutter does not rise in pawl
After effect, or after groove variations on toner cartridge, powder outlet cutter can be fixed on toner cartridge by fixing hole and be continuing with.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure：1st, powder outlet cutter；2nd, fixing hole；3rd, pawl.
Embodiment
Referring to the drawings, a kind of new powder outlet cutter of the present utility model, it is characterised in that：Including knife rest, described knife rest is consolidated
It is scheduled on toner cartridge, described toner cartridge is fixed in printer, the two ends of described powder outlet cutter are extended with pawl, and powder outlet cutter is stuck in into selenium
The groove coordinated again with pawl is set on drum, on described toner cartridge, and the upper end of the pawl of described powder outlet cutter is set by fixing hole 2.
Further, the edge of described powder outlet cutter is upturned, two parts formation right angle.
