Abstract
A kind of toner cartridge of wear-resisting type, it is related to a kind of laser printer technical field, sealing sponge is located at waste powder hopper both ends, for sealing the gap between photosensitive drums and waste powder hopper shell, the shape of cleaning blade is U-shaped, respectively there are one dog-ears at both ends, cleaning blade dog-ear is stepped ramp type, when being installed on waste powder hopper, it is close together close to the dog-ear of cleaning doctor and the cutting edge of cleaning doctor, the size of dog-ear is identical with the size of sealing sponge, and sealing sponge is mounted between cleaning blade and waste powder hopper shell so that 4 relative position in toner cartridge is respectively from top to bottom：Photosensitive drums, cleaning blade, sealing sponge and waste powder hopper shell, this scheme makes photosensitive drums be not in direct contact with sealing sponge, it will not be damaged because of rubs mutually, separately since scraping blade surface is smooth plane, sundries will not be accumulated, and the sealing sponge of bottom has certain elasticity, so even if photosensitive drums will not be caused to wear with photosensitive drums friction for a long time.
Description
Technical field
A kind of toner cartridge of wear-resisting type of the present invention, is related to a kind of laser printer technical field, particularly a kind of toner cartridge.
Background technology
Integral type selenium drum of laser printer by powder cabin, waste powder hopper, photosensitive drums, charging roller, cleaning doctor, go out powder scraper, magnetic
The main parts sizes such as roller and carbon dust form, and a toner cartridge is combined by certain structure, are installed in printer to develop
Imaging.Wherein waste powder hopper by waste powder hopper main body, cleaning doctor, photosensitive drums, " 7 " word felt and cleaning blade formed one closure
Space is scraped in waste powder hopper when photosensitive drums carry the carbon dust rotation for remaining in surface by cleaning doctor, opposite with cleaning doctor
Parallel position is flown out there are one waste powder hopper scraping blade with the powder that prevents from giving up after cleaning.Most of " 7 " word felt surface be wool or
Person's class wool fiber, bottom are sponge or polyurethane foam cotton, are contacted with photosensitive drums, play the role of sealing, if directly
" 7 " word felt is changed to sealing sponge material, after a period of use since photosensitive drums are rotating always, it may appear that sponge becomes
The problem of shape and leakage powder, and on the basis of prior art, in use for some time, " 7 " word felt surface will speckle with toner cartridge
The impurity such as carbon dust, powdered lubricant, shredded paper, these impurity cause photosensitive drums abrasion even to damage during being continuing with, shadow
The normal use of toner cartridge has been rung, has caused the irrational utilization of resource and economic loss.
Invention content
The present invention can reduce production cost, avoid photosensitive drums to solve the above problems, provide a kind of toner cartridge of wear-resisting type
Abrasion and damage.
Present invention employs following technical solutions：A kind of toner cartridge of wear-resisting type, includes powder cabin, waste powder hopper, photosensitive drums, charging
Roller, cleaning doctor go out powder scraper, magnetic roller, cleaning blade and sealing sponge.It is described go out powder scraper, magnetic roller and carbon dust be mounted on powder
On storehouse, the photosensitive drums, charging roller, cleaning doctor, cleaning blade and sealing sponge are mounted on waste powder hopper, waste powder hopper and powder cabin
It is combined into a toner cartridge.Shell, photosensitive drums, cleaning doctor, cleaning blade and the sealing sponge of the waste powder hopper form one and close
The space of conjunction, for storing useless powder, the sealing sponge is located at waste powder hopper both ends, for seal photosensitive drums and waste powder hopper shell it
Between gap, the shape of the cleaning blade is U-shaped, and respectively there are one cleaning blade dog-ear, cleaning blade dog-ear is step at both ends
Type, when being installed on waste powder hopper, dog-ear and the cutting edge of cleaning doctor close to cleaning doctor are close together, the size of dog-ear and close
The size for sealing sponge is identical, and sealing sponge is mounted between cleaning blade and waste powder hopper shell so that 4 is opposite in toner cartridge
Position is respectively from top to bottom：Photosensitive drums, cleaning blade, sealing sponge and waste powder hopper shell.This scheme make photosensitive drums not with it is close
Envelope sponge is in direct contact, will not be damaged because of rubs mutually, separately since scraping blade surface is smooth plane, will not accumulate miscellaneous
Object, and the sealing sponge of bottom has certain elasticity, so even if photosensitive drums will not be caused to grind with photosensitive drums friction for a long time
Damage.
A kind of advantageous effect of the toner cartridge of wear-resisting type of the present invention is：1st, the felt of high cost is changed to general sponge, dropped
Low cost；2nd, the abrasion of photosensitive drums is reduced, extends the service life of toner cartridge.
Description of the drawings
Attached drawing 1 is a kind of toner cartridge schematic diagram of the toner cartridge of wear-resisting type of the present invention, and attached drawing 2 is a kind of selenium of wear-resisting type of the present invention
Bulging waste powder hopper accessory schematic diagram, attached drawing 3 are that a kind of cleaning doctor of toner cartridge of wear-resisting type of the present invention and cleaning blade assembling are shown
It is intended to, attached drawing 4 is the present invention a kind of cleaning doctor and cleaning blade partial assembled schematic diagram of the toner cartridge of wear-resisting type.In figure：1 is
Waste powder hopper, 2 be cleaning doctor, and 3 be charging roller, and 4 be photosensitive drums, and 5 be powder scraper, and 6 be powder cabin, and 7 be magnetic roller, and 8 be carbon dust, 9
It is cleaning blade dog-ear for cleaning blade, 91.
Specific embodiment
The present invention is illustrated below in conjunction with the accompanying drawings：With reference to attached drawing 1, Fig. 2, Fig. 3 and Fig. 4, the present invention is a kind of wear-resisting
The toner cartridge of type includes waste powder hopper 1, cleaning doctor 2, charging roller 3, photosensitive drums 4, goes out powder scraper 5, is powder cabin 6, magnetic roller 7, carbon dust 8, clear
Clean scraping blade 9 and sealing sponge.It is described go out powder scraper 5, magnetic roller 7 and carbon dust 8 be mounted on powder cabin 6 on, the photosensitive drums 4, charging roller
3rd, cleaning doctor 2, cleaning blade 9 and sealing sponge are mounted on waste powder hopper 1, and waste powder hopper 1 and powder cabin 6 are combined into a toner cartridge.
Shell, cleaning doctor 2, photosensitive drums 4, cleaning blade 9 and the sealing sponge of the waste powder hopper 1 form the space of a closure, use
To store useless powder, the both ends for sealing sponge and being located at waste powder hopper 1, for sealing the sky between 1 shell of photosensitive drums 4 and waste powder hopper
Gap, the shape of the cleaning blade 9 is U-shaped, and respectively there are one cleaning blade dog-ear 91, cleaning blade dog-ear 91 is step at both ends
Type, when being installed on waste powder hopper 1, the cutting edge of dog-ear and cleaning doctor 2 close to cleaning doctor is close together, the size of dog-ear with
The size for sealing sponge is identical, and sealing sponge is mounted between 1 shell of cleaning blade 9 and waste powder hopper so that 4 in toner cartridge
Relative position is respectively from top to bottom：Photosensitive drums 4, cleaning blade 9, sealing 1 shell of sponge and waste powder hopper..
A kind of implementation method of the toner cartridge of wear-resisting type of the present invention is：Photosensitive drums 4 are not in direct contact with sealing sponge, Bu Huiyin
It is damaged for rubs mutually, but since 91 surface of cleaning blade dog-ear is smooth plane, after long-time use, surface is not
Sundries can be accumulated, and the sealing sponge of bottom has certain elasticity, can reduce the pressure between photosensitive drums 4 and cleaning blade dog-ear 91
Power so even if rubbing for a long time with photosensitive drums 4, will not cause photosensitive drums to be worn, so as to extend the service life of toner cartridge.
