Abstract
The invention discloses a toner cartridge for a laser printer. The toner cartridge comprises a box body, and a toner cabin, a toner feeding roller, a developing roller and a photosensitive cartridge which are arranged inside the box body, wherein the developing roller is arranged on one side of the toner cabin; a scraper is arranged above the developing roller; a permanent magnet is arranged inside the photosensitive cartridge; an upper cover of the toner cabin is provided with a toner inlet; two elastic sheets which are positioned in the toner cabin are arranged below the toner inlet; outer edges of the elastic sheets are tightly connected with a lower surface of the toner cabin through rivets; and inner edges of the two elastic sheets are adjacent to each other and matched in profiles, and fully cover the toner inlet together. Through arrangement of the permanent magnet in the photosensitive cartridge, the photosensitive cartridge is prevented from being damaged by direct contact with the developing roller. A toner adding way in which the toner inlet is matched with the elastic sheets is adopted, so that convenience is brought to use, and the problem that the toner inlet is kept in an exposed state since a user forgets to close the toner inlet is solved.
Description
Technical field
The present invention relates to a kind of printer accessory, specifically a kind of Se drum for laser printer.
Background technology
Toner cartridge is one of parts important in printer, and it not only determines the quality of print quality, and also determining user in use needs the money spent how many.In laser printer, the image-forming block of more than 70% concentrates in toner cartridge, and the quality of print quality is actually determined by toner cartridge to a great extent.
It is the work that in printer use procedure it is frequently necessary to do to powder adding of selenium drum, in prior art, some production firm has opened the powder input port with switch or valve to the new powder storehouse of toner cartridge, but generally, the structure slightly complicated of switch or valve, and can forget after sometimes adding powder to reset, making powder input port keep naked state, original switch or valve will lose its due meaning.
And the visualization way of existing toner cartridge requires that photosensitive drums directly contacts with developer roll, the damage for photosensitive drums is relatively big, and driving torque is also big, and each parts precision requires high and causes that bearing cost is high simultaneously, prints cost also unstable.And after once having developed, it is necessary to utilize cleaning balde that the carbon dust of the residual in photosensitive drums is wiped off, then charging roller is again to photosensitive drum charging, remove Polaroid after rest potential, then just can carry out secondary development work, step is relatively complicated.
Summary of the invention
It is desirable to provide a kind of Se drum for laser printer.
For realizing described purpose, the present invention provides following technical scheme:
A kind of Se drum for laser printer, including box body, and is located at the powder cabin of tray interior, powder feeding roller, developer roll and photosensitive drums, and described powder cabin side is provided with developer roll, and developer roll is arranged over scraper, and the inside of described photosensitive drums is provided with permanent magnet；Described powder cabin is covered with powder input port, powder input port be connected with being positioned at the shell fragment of powder cabin, described shell fragment is two lobes, and every outer rim of lobe shell fragment and the lower surface of powder cabin are fastenedly connected by tightening of rivet, and the two adjacent profiles in lobe shell fragment inner edge match and are jointly completely covered by powder input port.
Preferably, described permanent magnet is six and is distributed in the surrounding of photosensitive drums axis in star.
Preferably, described photosensitive drums side is provided with cleaning balde, and described cleaning balde is conductive plate, and it is connected with power supply by power line.
Preferably, knife bar is fixed in the upper end of described scraper, and lower end is free end, is provided with extension spring between free end and the knife bar of scraper.
Compared with prior art, the invention has the beneficial effects as follows:
1, the mode of permanent magnet that star is set in photosensitive drums is adopted, it is to avoid photosensitive drums directly contacts with developer roll, it is prevented that photosensitive drums damage.
What 2, employing powder input port and shell fragment were worked in coordination adds powder mode, by powder input port, powder cabin can be added powder easily, and the shell fragment being positioned at powder cabin after adding powder rebounds automatically, and namely powder input port is closed, will not cause that powder input port is in exposed state owing to forgetting to close.
3, cleaning balde and charging roller are united two into one, eliminate the trouble that charging roller manufactures, reduce cost, decrease pollution simultaneously.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
Refer to Fig. 1-4, in the embodiment of the present invention, a kind of Se drum for laser printer, including box body 1, and it is located at the powder cabin 14 within box body 1, powder feeding roller 4, developer roll 5 and photosensitive drums, described powder cabin 14 side is provided with developer roll 5, and the carbon dust in powder cabin 14 is delivered to after developer roll 5 in developer roll 5 surface attachment through powder feeding roller 4, developer roll 5 is arranged over scraper 7, and the carbon dust on described developer roll 5 is adsorbed to photosensitive drums 6 surface after scraper 7 drawout.
Knife bar 8 is fixed in the upper end of described scraper 7, and lower end is free end, is provided with extension spring 9 between free end and the knife bar 8 of scraper 7.Extension spring 9 can so that the free end of scraper 7 keeps clamped condition with the surface of developer roll 5.
The inside of described photosensitive drums 6 is provided with permanent magnet 10, the carbon dust being attached to developer roll 5 surface can be attached to the surface of photosensitive drums 6 under the effect of permanent magnet 10, it is to avoid photosensitive drums 6 directly contacts with developer roll 5, it is prevented that photosensitive drums 6 is damaged.Described permanent magnet 10 is six and is distributed in the surrounding of photosensitive drums 6 axis in star.
