Description

Selenium drum

[ technical field ] A method for producing a semiconductor device

The utility model belongs to the technical field of the printer accessory, concretely relates to selenium drum.

[ background of the invention ]

The toner cartridge is an important accessory in the printer, the toner cartridge is also called a photosensitive drum, more than 70% of imaging components are concentrated in the toner cartridge, and the quality of printing is actually determined by the toner cartridge to a great extent.

In the printing process, the traditional laser can penetrate through one end of the groove body on the powder scraping plate, and along with the increase of the printing times, printing black spots can be left on printing paper, so that the printing quality is seriously influenced.

[ Utility model ] content

In order to solve the existing problem existing in the background art, the utility model provides a selenium drum.

The utility model adopts the following technical proposal:

the utility model provides a selenium drum, includes the powder storehouse casing, powder storehouse internal rotation is equipped with the magnetic roll and the developer roll that are parallel to each other, the inside magnetic roll below that is located of powder storehouse casing is equipped with scrapes the powder board, the joint can be dismantled to the two side outsides of powder storehouse casing has first baffle and second baffle, it has the rectangular channel to scrape the shaping on the powder board, keeps the magnetic roll to be located developer roll top position and just right the rectangular channel is located rectangular channel right side one end sets up the portion that is in the light for block laser irradiation.

Further, the light blocking part is integrally formed in the rectangular groove.

Furthermore, the light blocking part is arranged at the right side end of the rectangular groove through a light blocking sheet.

Further, the light blocking sheet is a metal sheet or a non-metal sheet.

Further, the selenium drum further comprises an integrated protective cover, wherein the protective cover is detachably matched with the first baffle and covers the position between the first baffle and the second baffle, and the protective cover is used for protecting the developing roller.

Further, the protective cover is a plastic shell component.

The utility model has the advantages as follows:

one end of a rectangular groove formed on the powder scraping plate is sealed by light blocking, laser penetrates when the printing is carried out, the defect that black spots are formed on printing paper by the laser is avoided, and the printing quality is improved;

the safety cover of integral type replaces traditional detachable safety cover, when using directly take off can, it is convenient to use, does not cause the use influence.

[ detailed description ] embodiments

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention.

As shown in figures 1-4, the toner cartridge of the present invention comprises a powder bin housing 1, a magnetic roller 2 and a developing roller 3 parallel to each other are rotatably disposed in the powder bin housing 1, a powder scraping plate 4 is arranged below the magnetic roller 2 in the powder bin shell 1, a first baffle 5 and a second baffle 6 are detachably clamped outside the two sides of the powder bin shell 1, the powder scraping plate 4 is formed with a rectangular groove 41, the surface of the magnetic roller 2 in the toner cartridge is coated with organic materials which are pre-charged, when light irradiates, the irradiated part can generate resistance reaction, the transmitted data signal controls the emission of laser, the light scanning on the surface of the selenium drum is changed continuously, thus, a place can receive irradiation, when the surface of the charged toner cartridge passes through the inking roller, the charged portions attract toner particles, and the latent image becomes a true image. When the toner cartridge rotates in operation, the printing system conveys printing paper, the printing paper is charged with electric charges which have the same polarity as the toner cartridge surface but are much stronger, then the paper passes through the toner cartridge with toner, the toner on the toner cartridge surface is attracted onto the printing paper, an image is formed on the paper surface, a light source which is very important in the printing process during laser, after long-time work of transfer printing and printing, the ink can penetrate through a groove body on a powder scraping plate to cause the defect of forming printing black spots on printing paper, the printing quality is seriously influenced, therefore, the magnet roller 2 is kept in the upper direction of the developing roller 3 and is opposed to the rectangular groove 41, the light blocking portion 42 is provided at the right side end of the rectangular groove 41, effectively block laser through the portion of being in the light 42 to having solved present this problem defect, simple structure and reasonable in design have solved present not enough through simple design.

The current rectangular channel with scrape whitewashed board central line symmetry, in this scheme, the portion 42 that is in the light through foretell effectively supports and blocks laser transmission, certainly, the portion 42 that is in the light has multiple form structure, can one end of integrated into one piece rectangular channel 41 mend a part with rectangular channel 41, its length preferred is less than 1/3 of the whole length of rectangular channel 41, what this kind of structure scrape whitewashed board 4 direct integrative injection moulding can, technology shaping efficiency is high.

Of course, preferably, the light blocking portion 42 is installed on the rectangular groove 41 through a light blocking sheet, the light blocking sheet is a metal sheet or a non-metal sheet, and the light blocking sheet is directly fixed on the right side end of the rectangular groove 41, so as to effectively block laser transmission.

In addition, the traditional protective covers are all non-integrated, are rotatably arranged outside the powder bin shell 1 and are used for protecting the developing roller 3 from being damaged, the protective covers need to be opened when in use, are easy to block after being opened, so that the normal operation of other parts in the printer is influenced, and the opening and the assembly are complicated; therefore 7 safety cover of formula as an organic whole of safety cover of this selenium-enriched drum, like fig. 3, 7 detachably of safety cover match the lid and close on the outside between first baffle 5 and the second baffle 6, more, safety cover 7 is the plastics shell spare, directly buckles protection developer roll 3 with 7 of safety cover, when needing to adorn the printer with the selenium-enriched drum on, directly takes off the safety cover, and convenient quick not influence printer internals work again promptly, unusual practicality.

The utility model has the advantages that:

It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of the invention or which are equivalent to the scope of the invention are embraced by the invention.
