Description
Technical Field
The utility model relates to a seed kind of laser printer selenium drum seal structure.
Background
The laser printer is a common device in office and family, and the common laser printer for household or office mainly comprises a main machine body and a processing box which can be assembled and disassembled from the main machine body. The processing box mainly comprises a photosensitive drum, a developing roller, a powder bin shell and a waste powder bin shell, wherein the photosensitive drum is arranged in the waste powder bin shell; the developer roll adopts the magnetism roller and adorns in powder storehouse casing, be equipped with the boss in the powder storehouse casing relatively, be equipped with the half slot on the boss, the both ends of magnetism roller are arranged in the half slot, and be equipped with banding powder outlet between the half slot, it is sealed through sealed felt between boss top surface and magnetism roller, still be equipped with accuse powder scraper in the powder storehouse casing, scrape the carbon dust through accuse powder scraper and rub and take the charge after the developer roll adsorbs the carbon dust, the structure of scraper is including an iron support and rubber strip usually, the edge and the developer roll contact of rubber strip when iron support is fixed with powder storehouse casing, concrete structure is as follows: the developer roll contains magnetic core and aluminum pipe, be equipped with installation sand grip and play powder mouth on the powder storehouse wall of powder storehouse casing, it is sealed that the play powder mouth passes through joint strip, the part that the powder storehouse wall is located between installation sand grip and the play powder mouth constitutes welds a platform, joint strip's side and weld a platform welded seal, in former structure, the iron stand is fixed in installation sand grip top surface, then the rubber strip pastes on the iron stand, then extend away and developer roll surface contact, therefore at the installation sand grip, the rubber strip, it hides the powder region to form a similar triangle-shaped between the platform to weld, simultaneously by the direction of rotation in the aluminum pipe towards this triangle-shaped region, and the adsorption of the interior magnetic core of developer roll in addition, the carbon dust is piled up and can not be taken away by the developer roll and participate in the development or fall and form the carbon dust in getting back to the powder storehouse at this place always, thereby cause the waste.
And the structure before in order to guarantee the sealed of during operation, the position at the both ends of rubber strip need set up and seal the powder sponge, guarantees sealedly through the elastic contact who seals powder sponge and rubber strip. In addition, when the toner is dry in winter, the toner is easy to carry over high charges to form clusters, but the rubber strip and the surface of the developing roller can only be in line contact, so that the toner is difficult to be scraped uniformly, and finally, a ripple-like line is easy to generate during printing; and the elastic force of the two end parts of the rubber strip is weaker than that of the middle part, so the powder control effect of the two end parts is poor, and black edges are easy to appear during printing.
Therefore, the applicant designs a powder-hiding-free elastic powder control structure of a laser printer to solve the problems, but the structure is not complete enough, the end face of the sponge strip is partially in contact with and sealed with the side face of the sealing felt because the mounting convex strip is higher than the lug boss, but a gap is always generated between the end face of the sponge strip and the side face of the sealing felt because the side face of the sealing felt is soft and uneven, powder is easily piled in the gap, and carbon powder is also easily leaked from the gap after the piled powder is excessive.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides a laser printer selenium drum seal structure.
The utility model provides a technical scheme that its technical problem adopted is:
laser printer selenium drum seal structure, including powder storehouse casing and developer roll, the developer roll contains magnetic core and aluminum pipe, be equipped with the installation department on the powder storehouse wall of powder storehouse casing, weld sealing, boss, play powder mouth, it is sealed that the play powder mouth passes through joint strip, and joint strip's side and weld sealing welded seal, the terminal surface of installation department intersects with the side of boss, and is equipped with sealed felt, its characterized in that on the boss: be equipped with the elastic strip on the installation department, the elastic strip has a non-hole working face, this non-hole working face and developer roll surface contact, just the both ends of elastic strip all are equipped with the sealing, this sealing be located the boss and with the end face contact of sealed felt.
The installation department is for setting up the installation sand grip on the powder storehouse wall, the installation sand grip includes an medial surface, and the elasticity strip sets up on the medial surface, and this elasticity strip is located and hides in the powder region.
Be equipped with the double faced adhesive tape on the elastic strip, the elastic strip is pasted on the installation sand grip through the double faced adhesive tape.
The utility model has the advantages that: the utility model discloses an elasticity strip carries out accuse powder, elasticity strip elasticity itself is good, and contact with the developer roll through non-hole working face, the relatively smooth sclausura of non-hole working face, therefore can prevent that the carbon dust from blockking up the space and losing elasticity and accuse powder evenly, and after developer roll and non-hole working face contact extrusion, non-hole working face bending deformation pastes formation face contact on the developer roll, therefore scrape the carbon dust easily and scatter evenly, thereby printing quality has been improved, and need not to install again behind the elasticity strip and seal the powder sponge, original costly iron stand play powder sword has also been replaced simultaneously, the process has been simplified like this, the installation degree of difficulty has been reduced, thereby the cost has also been saved.
And the elastic strip is fixed on the inner side surface, so that a powder storing area is eliminated, the condition of carbon powder accumulation is avoided, the carbon powder can not be left and can fully participate in printing, the waste is avoided, the environment is protected, and the printing quantity is increased. Through the actual measurement of my company, the weight of the residual carbon powder in the selenium drum with the old structure is generally 8 g, and the weight of the residual carbon powder after the improvement of my company is only about 2 g.
And the clearance between the end face of the elastic strip and the side face of the sealing felt is eliminated through the sealing part, so that the sealing effect is improved.
