Abstract
The utility model is related to a kind of toner cartridge for preventing scraper from overturning, photosensitive drums, scraper and split type knife rest are equipped in shell；The split type knife rest includes tool fixing frame, movable knife rack, elastomer and guide post, the tool fixing frame is mounted on shell, the movable knife rack by guide post it is horizontally moveable be set to tool fixing frame front end, and elastomer is equipped between the tool fixing frame and movable knife rack, the scraper is fixed on the contact connectio of the surface on movable knife rack and with photosensitive drums.In this way, it can be squeezed when power will be overturn in scraper and slacken the extruding force being subject to, scraper is by natural resiliency reduction extensional deformation bending part simultaneously, the problem of being overturn to avoid scraper, toner cartridge is stable and reliable for performance, and print quality is guaranteed, and simple in structure, ingenious, production and processing is easy, and is conducive to mass production, widely available application.
Description
Technical field
The utility model belongs to printing consumables technical field more particularly to a kind of toner cartridge for preventing scraper from overturning.
Background technology
Currently, the scraper of original-pack toner cartridge and compatible toner cartridge on the market is all mounted on the knife rest of toner cartridge shell, it is fixed
Motionless, such as Fig. 1；But in print procedure, if the frictional force between photosensitive drums and scraper is excessive, extruding force that scraper is subject to
It is excessive, it is overturn so as to cause scraper, finally leads toner cartridge and can not work normally, and easy photosensitive drums and scraper are impaired, sternly
Ghost image rings print quality.
Utility model content
To solve the above-mentioned problems in the prior art, the utility model, which provides one kind, being squeezed power i.e. in scraper
The extruding force being subject to, automatic reduction are slackened when by overturning, avoids the toner cartridge of scraper overturning.
In order to solve the above technical problems, the utility model adopts the following technical solution：
A kind of toner cartridge for preventing scraper from overturning, shell is interior to be equipped with photosensitive drums, scraper and split type knife rest；The fission
Formula knife rest includes tool fixing frame, movable knife rack, elastomer and guide post, and the tool fixing frame is mounted on shell, and the movable knife rack passes through
Guide post is set to the front end of tool fixing frame horizontally moveablely, and elastomer is equipped between the tool fixing frame and movable knife rack, described to scrape
Knife is fixed on the contact connectio of the surface on movable knife rack and with photosensitive drums.
Further, the section of the movable knife rack is L-shaped, longitudinal knife frame plate by guide post it is horizontally moveable be set to
The front end of tool fixing frame, the scraper are mounted on the Horizontal tool-post plate of movable knife rack.
Further, the guide post is T shape cylinders, is fixed in tool fixing frame after passing through movable knife rack and elastomer.
Further, the elastomer is rubber strip.
The utility model has the beneficial effects that：
The utility model slackens the extruding being subject to through the above technical solutions, can be squeezed when power will be overturn in scraper
Power, while scraper, by natural resiliency reduction extensional deformation bending part, the problem of overturning to avoid scraper, toner cartridge performance is steady
Fixed reliable, print quality is guaranteed, and simple in structure, ingenious, and production and processing is easy, and is conducive to produce in enormous quantities, is general extensively
And application.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of existing toner cartridge；
Fig. 2 is a kind of structural schematic diagram of toner cartridge embodiment for preventing scraper from overturning described in the utility model；
Fig. 3 is that the structure that a kind of toner cartridge embodiment for preventing scraper from overturning described in the utility model does not install photosensitive drums is shown
It is intended to；
In figure：1-shell, 2-photosensitive drums, 3-scrapers, 4-split type knife rests, 41-tool fixing frames, 42-movable knife racks,
43-elastomers, 44-guide posts.
Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only explaining this
Utility model is not used to limit the utility model.
As shown in Figures 2 and 3：
The toner cartridge that can prevent scraper from overturning described in the utility model embodiment, shell 1 is interior to be equipped with photosensitive drums 2,3 and of scraper
Split type knife rest 4；The split type knife rest 4 includes tool fixing frame 41, movable knife rack 42, elastomer 43 and guide post 44, the stationary knife
Frame 41 is mounted on shell 1, the movable knife rack 42 by guide post 44 it is horizontally moveable be set to the front end of tool fixing frame 41, and it is fixed
Between knife rest 41 and movable knife rack 42 be equipped with elastomer 43, the scraper 3 be fixed on movable knife rack 42 and with photosensitive drums 2
Surface connects.Wherein, the section of the movable knife rack 42 is L-shaped, and longitudinal knife frame plate is horizontally moveable by guide post 44
Ground is set to the front end of tool fixing frame 41, and the scraper 3 is mounted on the Horizontal tool-post plate of movable knife rack 42；The guide post 44 can be
T shape cylinders are fixed on after passing through movable knife rack 42 and elastomer 43 in tool fixing frame 41；The elastomer 43 can be rubber strip.
When frictional force of the photosensitive drums 2 of toner cartridge described in the utility model between rotation process and scraper 3 is excessive, scraper
3 power that are squeezed will overturn and act power to movable knife rack 42, and 43 stress deformation of elastomer compresses at this time, 42 edge of movable knife rack
Guide post 44 is moved towards tool fixing frame 41, i.e., slackens the extruding force that scraper 3 is subject to, while scraper 3 is stretched by natural resiliency reduction
Bending part is opened up, the overturning of scraper 3 is avoided.
The above is preferred embodiments of the present invention, it is noted that for the ordinary skill of the art
For personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these are improved and profit
Decorations are also considered as the scope of protection of the utility model.
