The useless powder conveyer device internal structure schematic diagram of individual embodiment.
As shown in Figure 2,3, useless powder cleaning unit 21 is by clearing up the useless powder got off in each photosensitive drums 17, by useless powder conveyer device
50 are collected, and are transported to useless powder receiving box.Concrete useless powder conveyer device 50 can include that vertical transport box 51, level are defeated
Send box 52, and the cleaning spring 53 being arranged in vertical transport box 51.
This vertical transport box 51 is connected with useless powder cleaning unit 21 by upper end, and lower end is row's powder end, and it includes outside
Vertical tranporter 511, and it is arranged on the mobilizable spring receiving pipe 512 within vertical tranporter 511.
This horizontal feed box 52 includes that the horizontal conveying pipe 521 accommodating useless powder, horizontal conveying pipe 521 pass through one end with vertical
Row's powder end of delivery cartridge 51 connects, and the relative other end is provided with useless powder outlet 524, is provided with in horizontal conveying pipe 521
Useless powder is connected one end by with row's powder end, pushes to the screw rod 522 with helical-blade 523 of useless powder outlet 524, in level
Conveying pipe 521 is outside is provided with the driving means 525 driving screw rod 522 to rotate.
This cleaning spring 53 activity is placed on spring and accommodates in pipe 512.
Vertical tranporter 511 is tightly connected with horizontal conveying pipe 521, and spring accommodates pipe 512 and is movably mounted to vertically
In conveying pipe 511.
Under normal condition, cleaning spring 53 freely falls on screw rod 522 within spring accommodates pipe 512, when driving dress
Putting 525 driving screw rods 522 when rotating, the helical-blade 523 on screw rod 522 can promote cleaning spring 53 to transport upward always
Dynamic, the motion cleaning spring 53 then can rub with the sidewall of spring receiving pipe 512, and will stick to spring receiving pipe
Useless powder on 512 sidewalls is cleared up, thus prevents the phenomenon that useless powder transfer passage blocks.
In the present embodiment, cleaning spring 53 itself possesses certain space, thus without the whereabouts of the useless powder of impact, and
Utilize existing screw rod 522 to drive cleaning spring 53, both can reach to clear up the purpose of useless powder, need not again to increase new
Parts.The quantity of concrete vertical transport box 51 can be correspondingly arranged according to the quantity of photosensitive drums 17, the row of each vertical transport box 51
Powder end is connected with horizontal feed box 52 respectively.A cleaning spring 53 can be respectively mounted in each vertical transport box 51.
Fig. 4 is the structural representation of the spring receiving pipe of one embodiment of this utility model；Fig. 5 is spring shown in Fig. 4
Accommodate the profile of pipe.
As shown in Figure 4,5, further, movable for convenience of cleaning spring 53, this spring accommodates pipe 512 axially inside
Can be divided into active segment 5122 and limit section 5121, the diameter of active segment 5122 accommodates more than the diameter of restriction section 5121, spring
Pipe 512 is connected with horizontal feed box 521 by active segment 5122 one end.Use the structure of enlarged-diameter, useless powder can be increased
Throughput, reduces the probability of useless powder blocking channel, and meanwhile, active segment 5122 can make cleaning spring 53 have bigger movable sky
Between.
In an embodiment of the present utility model, this vertical tranporter 511 can use conical structure, and it is by with useless
Powder cleaning unit 21 connects one end, is connected one end to horizontal feed box 52, and diameter is gradually increased.After using this structure, both sides
Just accommodate the spring receiving pipe 512 that diameter differs, the diameter of conveying pipe of useless powder can be increased again, to reduce blocking probability.
Fig. 6 is the structural representation of the cleaning spring of one embodiment of this utility model.
As shown in Figure 6, further, in an embodiment of the present utility model, for avoiding cleaning spring 53 by spiral
Leaf 523 blocks, this cleaning spring 53 can include centre diameter maintaining segment 531, and be positioned at diameter maintaining segment 531 two ends to
The truncated cone closing in 532 that center of circle line gradually tapers up.Truncated cone closes up and 532 forms the domatic structure intersected with helical-blade 523,
Truncated cone closing in 532 can be avoided to be clamped in helical-blade 523 and spring accommodates between pipe 512 sidewall, thus improve cleaning
The animation effect of spring 53.
The effect of cleaning spring 53, inclining of the helical-blade 523 of this screw rod 522 is promoted for improving screw rod 522 further
Angle can be more than truncated cone closing in 532 angles of inclination to axial line.By this setting so that helical-blade 523 and cleaning bullet
The contact surface of spring 53 is two relative inclined planes, thus avoids because angle is the least, and cleaning spring 53 is stuck in helical-blade
Between 523 and spring receiving pipe 512 sidewall, can also avoid causing cleaning spring 53 because of Dun Ka simultaneously and manage with spring receiving
The sound of collision is produced between 512 sidewalls.
Although the description of several embodiments of the present utility model, but these embodiments are intended only as example and propose
, it is not intended to limit scope of the present utility model.These new embodiments, it is possible to implement in other various modes,
In the range of without departing from the main idea of utility model, it is possible to carry out various omission, replace, combine and change.These embodiments
All it is contained in scope of the present utility model and main idea with its deformation, and it is new to be contained in this practicality described in claims
In type and equivalency range thereof.
