Detailed description of the invention
It is the structural representation of this utility model Delevoping cartridge 2 as shown in Figure 1 and Figure 2.For the ease of understanding description, set all directions of Delevoping cartridge 2 in figure and be used in following description book, in Fig. 1, front left side direction is above, direction on the other side is below, in Fig. 1, the top of front left side is above Delevoping cartridge 2, on the other side for below Delevoping cartridge 2, upper left side in Fig. 1 is the left side of Delevoping cartridge 2, lower right side in Fig. 1 is the right side of Delevoping cartridge 2, wherein the front direction of Delevoping cartridge 2 is in the face of photosensitive drums box, " above " occurred in all parts of Delevoping cartridge 1 and Delevoping cartridge 1 in description, " below ", " left side ", " right side ", " on ", D score is all as the criterion with the direction shown in Fig. 1.
As shown in Figure 1 and Figure 2, Delevoping cartridge 2 includes: housing 20, and its storage inside has developing agent；Developer roll 60, rotatable it is supported in housing 20 front end, described developer roll 60 has and prolongs its axially extended axis A2, described housing 20 has the second side that the first side is axially relative with described first side with along developer roll, and the first side is on the right side of Delevoping cartridge 2, and the second side is in the left side of Delevoping cartridge 2, first side is the drive end of Delevoping cartridge 2, receiving the driving force of imaging device, the second side is the conducting end of Delevoping cartridge 2, it is achieved the electrical connection of Delevoping cartridge 2 and imaging device；First gear 21 is arranged on housing 20 first side；Second gear 22 is arranged on housing 20 second side；First lid 30, is installed on the first side of housing 20, covers at least some of first gear 21, be used for protecting and position the first gear 21, and the first lid 30 has the first auxiliary section 31 making developer roll 60 move away described photosensitive drums (not shown)；Second lid 40, is installed on the second side of housing 20, covers at least some of second gear 22, be used for protecting and position the second gear 22；Conducting bracket 50, between housing 20 and the second lid 40, conducting bracket 50 is provided with the second auxiliary section 51 making developer roll 60 move away described photosensitive drums (not shown).
Being illustrated in figure 3 the partial view of Fig. 1, when Delevoping cartridge loads photosensitive drums box, described developer roll 60 is along photosensitive drums faced by the front direction of Delevoping cartridge 2, and the first auxiliary section 31 has first 31a extended along the above-mentioned direction vertical in the face of direction.Being illustrated in figure 4 the partial view of Fig. 2, the second auxiliary section 51 has second 51a extended along the above-mentioned direction vertical in the face of direction.
It is the structural representation of conducting bracket 50 as shown in Figure 5, conducting bracket 50 is arranged on the second side of housing 20, second auxiliary section 51 is positioned on conducting bracket 50, conducting bracket 50 is additionally provided with developer roll shaft supporting part 52, supporting development roll shaft, the second auxiliary section 51 is positioned at after Delevoping cartridge 2 relative to developer roll shaft supporting part 52.
It is the view that projects along developer roll axial direction of Delevoping cartridge 2 first side as shown in Figure 6, is the view that projects along developer roll axial direction of Delevoping cartridge 2 second side as shown in Figure 7.Described Delevoping cartridge 2 also includes input portion 32, and input portion 32 has the axis A1 axially in parallel with developer roll, it is possible to the response external driving force axis around input portion 32 rotates, so that external motivating force to be delivered to the first gear 21.Delevoping cartridge 2 is when along developer roll axis projection, and the first auxiliary section 31 is between described developer roll axis A2 and input portion axis A1 (as shown in Figure 6), and the second auxiliary section 51 is between described developer roll axis A2 and input portion axis A1 (as shown in Figure 7).When developer roll 60 is from when removing photosensitive drums, the first auxiliary section 31 makes developer roll 60 move along the direction away from photosensitive drums, and the second auxiliary section 51 makes developer roll 60 move along the direction away from photosensitive drums.This kind of structural design, can make first 31a of the first auxiliary section 31 and second coordinate 51 second 51a can by stable pressure backward under the effect of photosensitive drums box, make developer roll 60 stable leave photosensitive drums.When along developer roll axis projection, first 31a is overlapping with developer roll 60, second 51a is overlapping with developer roll 60, this kind of structural design, the portion first face 31a and second 51a that is pressed of Delevoping cartridge 2 is close to developer roll 60 and is pressed by photosensitive drums box, it is ensured that developer roll 60 can reliable and stable separating photosensitive drums.
The developer roll 60 of Delevoping cartridge 2 contacts with photosensitive drums when forming image to supply toner to photosensitive drums, separates with photosensitive drums thus not supplying toner to photosensitive drums when being formed without image.When imaging device works, Delevoping cartridge 2 loads photosensitive drums box, developer roll 60 contacts with photosensitive drums, when developer roll 60 is formed without image, developer roll 60 needs to separate with photosensitive drums, pair of separated component (not shown) in photosensitive drums is by contacting with first 31a and second 51a the first auxiliary section 31 and the second auxiliary section 51 are pressed respectively, developer roll 60 is made to remove photosensitive drums, thus realizing separating of developer roll 60 and photosensitive drums.
Owing to the second lid 40 structures of Delevoping cartridge 2 are relatively complicated, second auxiliary section 51 is arranged on the second lid 40 to add the difficulty of the second lid 40 die sinking by prior art, add cost and owing to second covers 40 structure relative complex, error easily occurs during die sinking, make the second auxiliary section 51 inaccurate with the separated part location in photosensitive drums, it is impossible to realize separating of developer roll 60 and photosensitive drums very well.Second auxiliary section 51 is arranged on conducting bracket 50 by this utility model, solves the problems referred to above, can better realize separating of developer roll 60 and photosensitive drums.
Above example only in order to the technical solution of the utility model to be described, is not intended to limit；Although this utility model being described in detail with reference to previous embodiment, it will be understood by those within the art that: the technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent replacement；And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of this utility model.
