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 the 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, thereby forms the carbon dust image.
The charging roller of waste powder bin of carbon powder box is by conduction rack and the rotatable support of bracing frame in the prior art, conduction rack and bracing frame are provided with opening, because 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, transports the technological deficiency that charging roller easily comes off to solve the prior art waste powder hopper in the situation that do not assemble photo-sensitive cell 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 the bracing frame also comprise the limiting part that prevents that charging roller from coming off from described waste powder hopper.
Described charging roller comprises first end and the second end, and described limiting part is to be connected on the described waste powder hopper.
Described limiting part is shell fragment.
Described shell fragment comprises the installation portion that is connected on the described waste powder hopper and the abutting part that stops described charging roller to come off.
The lower limb interference fit of the installation portion of described shell fragment and described waste powder hopper, first end and the second end of the described charging roller of abutting part butt of described shell fragment.
Described limiting part is iron clamp.
Described iron clamp is connected on the support portion of described waste powder hopper.
Described iron clamp is provided with first end and the second end of the described charging roller of arc-shaped depression portion butt.
Described limiting part has two.
After adopting technique scheme, because first end and the second end position at the roll shaft that relatively charges are connected with limiting part, limiting part has stoped the first end of charging roller and the second end to come off from the arcuate socket of conduction rack and bracing frame, 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 part, this technical scheme technique is simple, and 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 among the utility model embodiment, technical scheme among 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 the 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 by screws in the powder outlet cutter 5 of waste powder hopper bottom, after cartridge 1 was packed image processing system into, conducting strip 4 contacted with input electrode in the image processing system.
Extremely shown in Figure 4 such as Fig. 3: the lower edge of waste powder hopper also is pasted with scraping blade 11 and prevents that carbon dust from leaking, the number of assembling steps of each parts of waste powder hopper is as follows: 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 cooperates, be provided with protruding 7a on the conduction rack 7, be provided with limited block 8a on the bracing frame 8, after the first end 9a of charging roller 9 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, the second end 9b of the limited block 8a restriction charging roller 9 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, because the protruding 7a of conduction rack 7 and the first end 9a interference fit of charging roller 9, so conducting strip 4 is sent to electricity on the charging roller 9 by spring 6 and conduction rack 7.
The first embodiment:
It is extremely shown in Figure 6 such as Fig. 5: after charging roller 9 is installed to waste powder hopper, two shell fragments 10 are connected to respectively the position of first end 9a and the second end 9b of relative charging roller 9, wherein the lower limb interference fit of the installation portion 10a of shell fragment 10 and waste powder hopper is fixed on the waste powder hopper shell fragment 10, and the abutting part 10b of shell fragment 10 first end 9a and the second end 9b of butt charging roller 9 prevent that charging roller 9 from coming off from conduction rack 7 and bracing frame 8 respectively, because shell fragment 10 is to be pressed on scraping blade 11 surfaces, thereby so the pressure that is applied on the scraping blade 11 of shell fragment 10 make its surface that more firmly sticks on waste powder hopper effectively prevent the carbon dust leakage.
The second embodiment:
Extremely shown in Figure 8 such as Fig. 7: after charging roller 9 installations, its first end 9a and the second end 9b are by conduction rack 7 and bracing frame 8 rotatable supports, then two iron clamps 12 are connected on the support portion 13 of waste powder hopper, wherein iron clamp 12 comprises arc-shaped depression portion 12a, so first end 9a and the second end 9b of the arc-shaped depression portion 12a butt charging roller 9 of iron clamp 12, thereby charging roller 9 can prevent effectively that under iron clamp 12 arc-shaped depression portion 12a withstand effects the first end 9a of charging roller 9 and the second end 9b 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 made amendment 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.
