Embodiment
Fig. 1,2,3,4,5,6,7 is respectively different conditions of the present utility model and different structure position diagram, the i.e. corresponding support structural representation of photosensitive drums power receiving portion and waste powder hopper, photosensitive drums power receiving portion and waste powder hopper assembly structure synoptic diagram, photosensitive drums and waste powder hopper fit-up gap control chart, the corresponding support structural representation of waste powder hopper, photosensitive drums and waste powder hopper assembly flow charts.
According to Fig. 1,2,3,4,5,6,7 structures that show, image generation unit and image developing transfer printing unit enter the engaging hole corresponding with it 4 by the hinge engagement of a pair of coaxial line, are close to faying face 3 and realize interconnecting.On the other hand, the utility model has omitted the description to image developing transfer printing unit and affiliated toner hopper and image developing transfer device.
Referring to Fig. 1,2,3,4,7, emphasis is described the constructional aspect between laser printer powder box photosensitive drums of the present utility model and the waste powder hopper.
Among Fig. 4,7, the end relative with the power receiving portion is provided with the support holes 5 that is positioned at its middle shaft part position on the photosensitive drums 1.Image generate frame 2 be provided with photosensitive drums 1 on the support plate 22 that adapts of the opposed end of power receiving portion.Support plate 22 is fixed in image and generates on the frame 2.Pin 7 pass support plate 22 and on it corresponding manhole 6 penetrate in the support holes 5 of photosensitive drums 1, end relative with the power receiving portion on the photosensitive drums 1 is fixed.At this position, photosensitive drums 1 can be around pin 7 rotations by support holes 5.
Among Fig. 1, the middle part cylinder of photosensitive drums 1 is photosensitive position 11, is provided with the spiral gear 12 that is used to drive developing apparatus with the cylinder edge of diameter substantially with photosensitive position 11 near its power receiving portion.Axially extend outward the rotor 13 of a diameter less than photosensitive position 11 cylinder diameters in its power receiving portion along it, next-door neighbour's rotor 13 is to being outside equipped with transmission of power distortion boss 14.Adapt with power receiving portion on the photosensitive drums 1, image generates frame 2 and is provided with support plate 20.The inside surface of support plate 20 is plane.Under the state of the photosensitive drums 1 intact image generation unit of packing into, this inside surface perpendicular to photosensitive drums 1 axially and be in close proximity near the spiral gear 12 axial outer side edges edges on the cylinder power receiving portion of photosensitive drums 1.Support plate 20 is provided with circular hole 23.Circular hole 23 is coaxial with photosensitive drums 1 under the state of the photosensitive drums 1 intact image generation unit of packing into, and its diameter is equal to or slightly greater than the external diameter of rotor 13 of the power receiving portion of photosensitive drums 1, is supported in the circular hole 23 at installment state lower rotor part 13.Along photosensitive drums 1 axially on the outside surface of external support plate 20, be provided with circular hole 23 with the annulus 21 of shaft diameter greater than circular hole 23.Annulus 21 inner cylinder faces are provided with the symmetry projection 24 of pointing to its axis.Annulus 21 cooperates the location at the transmission of power position between realization powder box and the external host to cooperate with projection 24.
Fig. 2 illustrates, and the power receiving portion of photosensitive drums 1 is engaged in the circular hole 23 by rotor 13, and the external cylindrical surface of rotor 13 and the inner cylinder face of circular hole 23 are fitted mutually at this moment, and transmission of power distortion boss 14 stretches out in outside the outside surface of support plate 20.Rotor 13 can rotate with respect to circular hole 23.
Fig. 4,5,6,7 illustrates the installation process of photosensitive drums 1 on image generation frame 2.At first, the transmission of power of photosensitive drums 1 is twisted boss 14 pass from circular hole 23, at this moment, the axis of rotor 13 and photosensitive drums 1 and circular hole 23 form certain included angle.Afterwards, make it produce an elastic deformation along the axially outwards light hydraulic support plate 22 of photosensitive drums 1, reserve a distance and be a bit larger tham the space of photosensitive drums 1 length, make photosensitive drums 1 accept the rigging position that relative end enters support plate 22, lock in the circular hole 5 with pin 7 again with power.For the support plate 22 that guarantees the opposite end produces suitable elastic deformation amount when photosensitive drums is installed, prevent that it from forming permanent strain, and on it is axial, produce excessive relative displacement between control photosensitive drums and the waste powder hopper, under installment state, the distance of cylindrical rotor 13 axial inside circumference and support plate 20 inside surfaces, the photosensitive drums 1 end axial external surface at support holes 5 places and the distance of support plate 22 inside surfaces, the two sum is arranged in 0.5～1.5 millimeter scope, as shown in Figure 3.
