Description

Leakage-proof toner cartridge

Technical Field

The utility model relates to a cartridge, in particular to prevent leaking powder cartridge.

Background

As shown in fig. 1 and 2, currently, a sealing method is formed by a way of processing a powder bin body of a compatible brother toner cartridge, wherein the sealing way is formed by a way of forming by a developing roller, two felts, a long sponge, a powder outlet knife, a square sponge and a sealing scraping blade; the surface layer of the felt 1a used in the prior art is designed to be punctiform plush, the surface of the felt becomes smoother after the felt is rotated and rubbed by a developing roller, and a good sealing effect cannot be achieved, so that carbon powder is easy to flow and leak from the surface, the surface of the original felt 1a is loose, not compact and poor in wear resistance, the torsion of the carbon powder box is not easy to solve, and a layer of silicone grease is required to be coated on the surface of the felt to consolidate the sealing effect; in the prior art, two square sponges 3a are adhered to a powder outlet knife 2a and laminated with a felt 1a to form sealing, and because the steel sheet of the powder outlet knife 2a is provided with a bent design, a small gap is formed after the bent sponge contacts the surface of the felt 1a, the leveling effect cannot be achieved, and sealing silicone grease is coated at the gap to achieve sealing; therefore, the prior art has the following defects: 1. the labor cost is increased 2, the material cost is increased; 3. the toner has a problem of leakage.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that overcome prior art not enough, provide one kind and improve production efficiency, save the cost and effectively solve the more big powder cartridge that prevents leaking of cartridge torsion.

The utility model adopts the technical proposal that: the utility model discloses a powder storehouse with set up in developer roll on the powder storehouse, the play powder mouth department in powder storehouse is provided with out the powder sword, the developer roll is located go out the one end of powder sword, go out the both sides of powder sword with all paste between the both sides of developer roll and have erect the hair felt, go out the square sponge in the portion of bending and the portion of bending of powder sword cancellation original both ends, will it becomes the straight powder sword that goes out of no portion of bending to go out the powder sword.

Furthermore, the vertical hair felt comprises a sponge body, a plurality of hairs are transversely arrayed on the surface layer of the sponge body, and the hairs are uniformly oriented towards the inner direction of the powder bin when the vertical hair felt is pasted.

Furthermore, the powder discharging knife comprises a knife rest and a straight steel sheet, the straight steel sheet is fixed on the knife rest, and the straight steel sheet and the developing roller are parallel and tangent

The utility model has the advantages that: because the utility model comprises a powder bin and a developing roller arranged on the powder bin, a powder outlet of the powder bin is provided with a powder outlet knife, the developing roller is positioned at one end of the powder outlet knife, the two sides of the powder outlet knife and a vertical hair felt are respectively stuck between the two sides of the developing roller, the vertical hair felt comprises a sponge body, a plurality of hairs are arranged on the surface layer of the sponge body in a transverse array, when the vertical hair felt is stuck, the hairs move towards the inner direction of the powder bin uniformly, the design can effectively prevent the carbon powder from leaking outwards, the powder outlet knife cancels the bending parts at the two ends and the square sponge on the bending parts, the powder outlet knife is changed into a straight powder outlet knife without the bending parts, the design solves the problem that the bending parts of the powder outlet knife press the felt to generate gaps, and cancels the coating of sealing silicone grease, so the utility model cancels the step of coating sealing silicone rubber, the production efficiency is improved, the production cost is reduced, in addition, the improved vertical hair felt enables the developing roller to achieve a tight sealing effect with the vertical hair felt in the rotating process, meanwhile, the step of coating silicone grease on the vertical hair felt can be omitted due to the sealing characteristic of the vertical hair felt, the production efficiency is improved, the production cost is reduced, the wear resistance of the vertical hair felt is good, and the problem that the torsion of the carbon powder box is large can be effectively solved.

Detailed Description

As shown in fig. 3 to 5, in this embodiment, the utility model discloses a powder storehouse 1 with set up in developer roll 2 on the powder storehouse 1, the powder outlet department in powder storehouse 1 is provided with out powder sword 3, developer roll 2 is located go out the one end of powder sword 3, go out the both sides of powder sword 3 with it has perpendicular hair felt 4 all to paste between the both sides of developer roll 2, go out the square sponge in the portion of bending and the portion of bending that powder sword 3 cancelled original both ends, will go out the straight powder sword that powder sword 3 changes into the portion of no bending.

In this embodiment, the raised hair felt 4 comprises a sponge body, a plurality of hairs are transversely arrayed on the surface layer of the sponge body, and the hairs are uniformly oriented towards the inner direction of the powder bin 1 when the raised hair felt 4 is stuck; when the felt is processed and produced, the trend of the felt is required to be uniformly oriented in one direction, and finally the vertical wool felt 4 with the required size is formed by punching the designed size of a plate.

Go out powder sword 3 and include knife rest 31 and straight steel sheet 32, straight steel sheet 32 is fixed in on the knife rest 31, just straight steel sheet 32 with the parallel tangent of developer roll 2, the torsion of the reduction product that this design can be great, and need not to paste square sponge 3a again, has effectively solved 3 department of bending of powder sword and has pressed the felt and produce the problem in gap, has cancelled simultaneously and has scribbled sealed silicone grease.

The utility model discloses be applied to the technical field of printing consumables.

While the embodiments of the present invention have been described in terms of practical embodiments, they are not intended to limit the scope of the invention, and modifications of the embodiments and combinations with other embodiments will be apparent to those skilled in the art in light of the present description.
