A kind of cartridge

Technical field

The utility model relates to a kind of dismountable cartridge that is arranged in image processing system.

Background technology

Prior art discloses a kind of cartridge, and cartridge is dismountable being arranged in image processing system, and wherein cartridge comprises the magnetic roller, photo-sensitive cell, and carbon dust is transported on photo-sensitive cell by the magnetic roller, so forms the carbon dust image on the surface of photo-sensitive cell.

as extremely shown in Figure 2 in Fig. 1, the disclosed cartridge of prior art comprises photo-sensitive cell 1, wherein photo-sensitive cell 1 by pin 2 by powder storehouse end cap 3 rotary supports, due in daily production run, after each assembling parts of cartridge is completed, need to prevent that it is exposed for the photosensitive drums 1 black paper of parcel, completing this step needs pin 2 is extracted from the cylindrical hole 3a of powder storehouse end cap 3, thereby an end of photosensitive drums 1 is pulled down, because the terminal surface of the cylindrical hole 3a on the end face of pin 2 and powder storehouse end cap 3 is concordant, therefore the logical common tool 4 of the operating personnel drum end that inserts photosensitive drums 1 locates to prize pin 2 with the gap of powder storehouse end cap 3, the excessive instrument 4 of can causing damages photosensitive drums 1 and powder storehouse end cap 3 if operating personnel exert oneself, cause the print quality of cartridge bad.

The utility model content

The utility model provides a kind of cartridge, and solving prior art in the process of dismounting cartridge photosensitive drums, instrument prizes the technological deficiency that pin easily damages photosensitive drums end and powder storehouse end cap from the gap of photosensitive drums and powder storehouse end cap.

In order to solve above technical matters, the technical scheme that the utility model is taked is:

A kind of cartridge that is removably mounted in image processing system, described cartridge comprises box body, be positioned at the powder storehouse end cap of described box body side, be positioned at the photo-sensitive cell of box body and be arranged on the end cap of described powder storehouse be positioned at described powder storehouse end cap on the pin that coordinates of cylindrical hole, described pin can insert in described photo-sensitive cell and at the described photo-sensitive cell of described powder storehouse end cap upper support, is provided with the teat of giving prominence at described cylindrical hole terminal surface on described pin.

Be provided with a lug cap on described teat, be provided with groove between described lug cap and described cylindrical hole terminal surface.

Described groove is annular groove.

The cross-sectional area of described teat is larger than the cross-sectional area of the in-profile of described cylindrical hole.

After adopting technique scheme, be provided with groove on teat due to pin, therefore the groove of instrument insertion pin can be extracted pin easily, this scheme technique is simple, cost is low, and the instrument in the process of prior art dismounting cartridge photosensitive drums of having solved easily damages the technical matters of photosensitive drums end and powder storehouse end cap.

Embodiment

For the purpose, technical scheme and the advantage that make the utility model embodiment clearer, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.

as shown in Figure 3, cartridge 10 is assembled by the waste powder hopper 17 that photosensitive drums 11 is installed and powder storehouse 18 that magnetic roller 13 is installed, cartridge 10 comprises pin 12 and powder storehouse end cap 16, wherein be provided with cylindrical hole 16a on powder storehouse end cap 16, and cylindrical hole 16a also comprises terminal surface 16b, pin 12 coordinates with the cylindrical hole 16a of powder storehouse end cap 16, the end of photosensitive drums 11 is provided with gear 11a, powder storehouse 18 also comprises magnetic roller 13, idle pulley 14 and puddle support gear 15, wherein idle pulley 14 meshes simultaneously with magnetic roller gear 13a and puddle support gear 15, after cartridge 10 is packed image processing system into, thereby pin 12 contacts conductive supporting photosensitive drums 11 with input electrode (not shown) in machine.

Embodiment one:

To shown in Figure 6, pin 12 comprises the teat 12a that gives prominence in the cylindrical hole 16a terminal surface 16b outside, wherein is provided with annular groove 12b on teat 12a as Fig. 4.

the cylindrical hole 16a outside of giving prominence at powder storehouse end cap 16 due to the annular groove 12b on pin 12, therefore in the process of the photosensitive drums 11 black paper of parcel, the annular groove 12b that only need insert with the top 19a of instrument 19 pin 12 stirs outside cylindrical hole 16a, can easily extract pin 12, thereby after pulling down photosensitive drums 11 and wrap up the black paper of one deck, the photosensitive drums 11 that then will be enclosed with black paper is retightened on the powder storehouse of cartridge 10 end cap 16 by pin 12, effect due to annular groove 12b on pin 12, make the time of the cartridge 10 photosensitive drums 11 black paper of parcel shorter, improved the efficiency of assembling of cartridge 10, avoided simultaneously in the process of dismounting photosensitive drums 11 instrument 19 to damage photosensitive drums 11 and powder storehouse end cap 16.

Embodiment two:

To shown in Figure 10, be provided with teat 12c as Fig. 7 on pin 12, teat 12c is the terminal surface 16b outside of giving prominence at cylindrical hole 16a.And the cross-sectional area of teat 12c is larger than the cross-sectional area of cylindrical hole 16a in-profile.

therefore in the process of the photosensitive drums 11 black paper of parcel, the teat 12c that only need stir with the top 19a of instrument 19 pin 12 stirs outside cylindrical hole 16a, can easily extract pin 12, thereby after pulling down photosensitive drums 11 and wrap up the black paper of one deck, the photosensitive drums 11 that then will be enclosed with black paper is retightened on the powder storehouse of cartridge 10 end cap 16 by pin 12, effect due to the pin 12 upper process 12c of section, make the time of the cartridge 10 photosensitive drums 11 black paper of parcel shorter, improve the efficiency of assembling of cartridge 10, avoided simultaneously in the process of dismounting photosensitive drums 11 instrument 19 to damage photosensitive drums 11 and powder storehouse end cap 16.

It should be noted that at last: above embodiment only illustrates the technical solution of the utility model, is not intended to limit; Although with reference to previous embodiment, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of each embodiment technical scheme of the utility model.
