Abstract
The utility model discloses a waste powder storehouse of a carbon powder box. The waste powder storehouse of the carbon powder box comprises an electric conduction frame, a support and a charging roll, wherein the charging roll is arranged on the electric conduction frame and the support in a rotatable mode. The charging roll comprises a steel shaft and a rubber layer which is encircled around the steel shaft and can be compressed. A limit component is arranged on the waste powder storehouse of the carbon powder box, wherein the limit component is used for limiting the movement of the charging roll. The limit component comprises a locating part and a limit part which accommodates the steel shaft of the charging roll. Due to the fact that the end portion of the steel shaft of the charging roll is limited by the limit component, the charging roll can be effectively prevented from falling off from the waste powder storehouse of the carbon powder box.
Description
Technical field
The utility model relates to a kind of waste powder hopper of cartridge.
Background technology
Prior art discloses a kind of waste powder hopper of cartridge, cartridge is dismountable being installed in image processing system, wherein cartridge comprises charging roller, photosensitive drums, by charging roller to photosensitive drum charging, then photosensitive drums exposure forms electrostatic latent image, transmits the electrostatic latent image part of carbon dust on the photosensitive drums by developer roll, thus formation carbon dust image.
In prior art, the charging roller of waste powder bin of carbon powder box is by conduction rack and the rotatable support of bracing frame, conduction rack and bracing frame are provided with opening, due in the process of transportation, waste powder bin of carbon powder box is not generally all installed photosensitive drums, so the two ends of the roll shaft that charges easily come off from the opening part of conduction rack and bracing frame, thereby need to re-assembly, increase time cost.
The utility model content
The utility model provides a kind of waste powder hopper of cartridge, to solve the prior art waste powder hopper in the situation that do not assemble photo-sensitive cell and transport, the technological deficiency that charging roller easily comes off from conduction rack and bracing frame.
In order to solve above technical matters, the technical scheme that the utility model is taked is:
A kind of waste powder hopper of cartridge, described waste powder hopper comprises conduction rack, bracing frame and the rotatable charging roller that is supported on described conduction rack and bracing frame, described charging roller comprises the steel axle and is looped around compressible rubber layer on the steel axle, be provided with the limiting component that the described charging roller of restriction moves on described waste powder hopper, described limiting component comprises the location division and holds the limiting section of described charging roller steel axle.
Described location division is fixed by screws on described waste powder hopper.
Described limiting component has two, is arranged on respectively the two ends of described charging roller steel axle.
After adopting technique scheme, because limiting component is fixed on charging roller on waste powder hopper firmly, therefore waste powder hopper is not in the situation that assemble photo-sensitive cell and transport, charging roller can not come off from conduction rack and bracing frame under the effect of limiting component, this technical scheme technique is simple, high efficient and reliable has avoided charging roller to come off from waste powder hopper.

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 1, cartridge 1 comprises the handle 2 that is arranged on waste powder hopper and the powder filling port 3 of filling carbon dust, as shown in Figure 2, waste powder hopper comprises conducting strip 4 and is fixed on the powder outlet cutter 5 of waste powder hopper bottom, wherein be provided with two pilot hole 5a on powder outlet cutter 5, after cartridge 1 is packed image processing system into, conducting strip 4 contacts with input electrode in image processing system, as Fig. 3 to shown in Figure 4: limiting component 10 is provided with location division 10a and spacing hole 10b, and wherein charging roller 9 comprises first end 9a and the second end 9b of steel axle and is looped around rubber layer 9c on the steel axle.
The number of assembling steps of each parts of waste powder hopper is as follows: first step: as shown in Figure 2, at first with the assembly of spring 6 with conduction rack 7, spring 6 is mounted to respectively waste powder hopper with the assembly of bracing frame 8, wherein contact with conducting strip 4 with the spring 6 that conduction rack 7 coordinates, and be provided with protruding 7a on conduction rack 7, be provided with limited block 8a on bracing frame 8.Second step: as shown in Figure 4, the spacing hole 10b that first end 9a and the second end 9b of charging roller 9 steel axles inserted respectively limiting component 10 also fits in one.third step: as shown in Figure 5, the assembly of charging roller 9 and limiting component 10 is mounted to waste powder hopper, this moment, first end 9a and the second end 9b of charging roller 9 steel axles snapped in along the opening of conduction rack 7 and bracing frame 8 respectively, and the pilot hole 10a of limiting component 10 and the pilot hole 5a of powder outlet cutter 5 alignment, then be fixed on firmly limiting component 10 and powder outlet cutter 5 on waste powder hopper with screw 11, after the first end 9a of charging roller 9 steel axles and the second end 9b are respectively by conduction rack 7 and bracing frame 8 rotary supports, the first end 9a interference fit of the protruding 7a of conduction rack 7 and charging roller 9 steel axles, the second end 9b of the limited block 8a restriction charging roller 9 steel axles of bracing frame 8 moves axially, therefore can better guarantee the bearing accuracy of charging roller 9, after cartridge is packed image processing system into, first end 9a interference fit due to protruding 7a and the charging roller 9 steel axles of conduction rack 7, therefore conducting strip 4 is sent to electricity on charging roller 9 by spring 6 and conduction rack 7.
The spacing hole 10b of limited parts 10 is spacing respectively due to the first end 9a of charging roller 9 steel axles and the second end 9b, thereby has prevented that effectively charging roller 9 from coming off from conduction rack 7 and bracing frame 8.
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.
