Embodiment
Referring to Fig. 1 and Fig. 2, powder box 100 is positioned over laying on the platform 21 of residual powder cleaning equipment 200, that is to say, platform 21 provides a placement space for powder box 100.Powder box 100 has been set up with the electric supply installation 23 of residual powder cleaning equipment 200 by path 231 and has been electrically connected.Except platform 21, electric supply installation 23, residual powder cleaning equipment 200 also comprises a drive unit that driving force can be provided to powder box, a transfer device and a cleaning device.
In the present embodiment, drive unit only represents schematically with driving head 22 that driving projection 2a direct and powder box meshes during its work, so that photosensitive drums 2 rotations, thereby make powder box enter surplus powder removing work.Drive unit can be made as one with platform 21, also can be split.In addition, drive unit also can take to utilize gear to take turns the mode that is meshed, perhaps alternate manner with powder box drum end tooth.The concrete formation of drive unit is not particularly limited, and it can provide the driving force of Yu Fenqing to get final product to powder box.Drive unit preferably directly drives the miscellaneous part of photosensitive drums rather than powder box, and its reason is that the driving force of drive unit output is less comparatively speaking, thereby energy-conservation.
Transfer device mainly comprises transfer roll 24, and it also comprises transfer voltage generator and transfer printing drive unit.Transfer voltage is provided by path 232 by the electric supply installation of residual powder cleaning equipment.For simplified design, the power of transfer roll can be provided by the drive unit of residual powder cleaning equipment.
Cleaning device comprises a cleaning doctor 25 (referring to Fig. 5) and a surplus powder storage unit 26.
Referring to Fig. 3 and Fig. 4, for say something clear for the purpose of, the box body framework of powder box 100 is omitted, only stays critical piece, comprises charging roller 1, photosensitive drums 2, developer roll 3 and powder delivery cutter 4.Drive the end that projection 2a is located at photosensitive drums 2.After powder box 100 placed on the platform 21, its photosensitive drums 2 placed the top of transfer roll 24 abreast, and the distance of a common printer paper thickness is arranged between the two approximately.
Below in conjunction with Fig. 5 and Fig. 6, the principle of work and the surplus powder collection process of residual powder cleaning equipment are done a detailed explanation.
The weak negative electricity of carbon dust band in the present embodiment is perhaps through the weak negative electricity of band with powder delivery cutter friction back.To be placed on the platform 21 and after being driven through the powder box 100 of test earlier, photosensitive drums 2, developer roll 3 begin to rotate.Residual carbon dust at first is developed the surface that roller 3 interior magnetic cores are adsorbed onto developer roll 3 in the developing chamber.With the rotation of developer roll 3, the carbon dust of its surface adsorption 10 moves to developer roll 3 and photosensitive drums 2 immediate positions through powder delivery cutter 4 after regular.In this position, owing to loaded negative DC voltage on the developer roll 3, form deflecting electric field between the photosensitive drums 2 of developer roll 3 and 0 current potential, the attractive force that the carbon dust 10 of negative electricity is broken away from magnetic core a little less than the band under effect of electric field is transferred to the surface of photosensitive drums 2 from developer roll 3.Subsequently, photosensitive drums 2 lip-deep carbon dusts 10 forward position near transfer roll 24 to photosensitive drums, form deflecting electric field between the photosensitive drums 2 owing to transfer roll 24 that has loaded positive DC voltage and 0 current potential, carbon dust 10 attracted to the surface of transfer roll 24 under the effect of electric field force.Subsequently, the carbon dust 10 on the transfer roll 24 scrapes at the downstream end of the transfer roll sense of rotation scraper 25 that is cleaned, and is collected in the storage unit 26, and the residual carbon dust value in developing chamber, on developer roll 3 and the photosensitive drums 2 reaches till the requirement.Reveal in order to collect carbon dust better and effectively to prevent, storage unit 26 can a built-in or external negative pressure accepting unit, and carbon dust is collected in the negative pressure accepting unit the most at last like this.Because the speed that carbon dust is transferred to transfer roll is far longer than print speed, so that this mode is removed surplus powder is more efficient, and surplus powder is collected afterwards recycling.
The above-mentioned voltage that is carried on developer roll 3 or the transfer roll 24 is not limited to direct current, makes carbon dust that the deflecting electric field that shifts take place as long as can form.The purpose of using direct current is that entire equipment is worked together is more stable, quickens to remove the progress of surplus powder.
In the above-mentioned enforcement, can adjust the rotating speed of each parts and the speed that each on-load voltage is accelerated or the surplus powder that slows down is removed.The rotating speed of transfer roll 24 is more preferably greater than the rotating speed of photosensitive drums 2, and surplus like this powder transfer printing will be more efficient.
The foregoing description also has various deformation, such as transfer roll is replaced with transfer belt, cleaning doctor is changed into other cleaning means etc., and it is all within protection domain of the present utility model.
