Embodiment
As accompanying drawing 1, a kind of handle box shown in accompanying drawing 2, comprise photosensitive drums 1, developer roll 2, powder feeding roller 3, the powder storehouse 4 and the waste powder hopper that are formed by powder storehouse housing, end cap 13 members such as grade, also comprise the gear set that is arranged on handle box end, gear set includes some gears, some of them direct geared is arranged on the axle head of above-mentioned running roller, other gears are on the cylinder being mounted on powder storehouse 4, after gear set is arranged on handle box, end cap 13 is installed on handle box again, cover gear set, play the effect of protection gear, make gear can not come off from running roller axle head or cylinder simultaneously.
As shown in Figure 3, on the housing in powder storehouse 4, be provided with the notch 5 for powder feeding roller 3 is installed, the bore of described notch 5 is identical with the diameter of above-mentioned powder feeding roller 3 axle heads, thus the axle head of powder feeding roller 3 can directly install and be positioned in notch 5, do not use the component of bearing or support and so on.In above-mentioned notch 5, be provided with the position-limit mechanism 6 moving for limiting powder feeding roller 3 axle heads, the displacement of restriction powder feeding roller 3, can be not mobile to continued by force direction, avoided powder feeding roller 3 further developer roll 2 to be caused to extruding, ensures the development quality of handle box.
The utility model is by the interior position-limit mechanism 6 that arranges of notch 5, thereby make powder feeding roller 3 in the situation that axle head reduces bearing or support, still can be good at work, and reduced number of components, just reduce dimension chain, reduced rigging error, improved the processing quality of product.Further, can also simplify the packaging technology of product, reduce the production cost of product.
About gear set, 3 is known with reference to the accompanying drawings, and the gear in described gear set comprises several idle pulleys and is arranged on respectively the driven wheel of above-mentioned photosensitive drums 1, developer roll 2 axle heads.Idle pulley is used for connecting each driven wheel, plays transmission power and changes the effect of velocity of rotation, and the utility model is provided with the first idle pulley 9 for connecting developer roll driven wheel 7 and powder feeding roller driven wheel 8.The speed of rotating according to each running roller, the difference of the number of turns, the diameter of driven wheel and the number of teeth are also different, and described the first idle pulley 9 preferably uses doubly-linked tooth, and doubly-linked tooth can change the ratio of gear between running roller, reduces the number of gear, makes product can become miniaturization.
When handle box work, first the power source providing from image forming apparatus acts on photosensitive drum driving gear 10, photosensitive drum driving gear 10 is connected with developer roll driven wheel 7, drive developer roll 2 to rotate, developer roll driven wheel 7 is connected with the first idle pulley 9, the first idle pulley 9 is connected with powder feeding roller driven wheel 8 again, drives powder feeding roller 3 to rotate.Other member in handle box, for example puddle support also can rotate under the drive of gear set.
Can further be learnt the stressing conditions of powder feeding roller 3 by the course of work of said gear group, accompanying drawing 4 by reference to the accompanying drawings 3,, in the time that handle box is worked, take illustrated direction as benchmark, photosensitive drums 1 clockwise rotates, developer roll 2 rotates counterclockwise, and then can learn that powder feeding roller 3 clockwise rotates.The first idle pulley 9, in the process of rotating, can apply the directed force F t described in accompanying drawing 5 to powder feeding roller driven wheel 8, and this power Ft has comprised a power Ft1 to developer roll 2 directive effects, and Fd is the acting force of developer roll 2 to powder feeding roller 3.In the time that Ft1 is greater than Fd, powder feeding roller 3 moves to developer roll 2; Otherwise in the time that Ft1 is less than Fd, powder feeding roller 3 dorsad developer roll 2 moves.When powder feeding roller 3 is when developer roll 2 moves dorsad, the inwall of notch 5 has served as the effect of position-limit mechanism 6, as shown in Figure 6, does not need to arrange projection in notch 5.In the time that powder feeding roller 3 moves to developer roll 2, position-limit mechanism 6 is arranged on the projection of notch 5 opening parts.
Below, be greater than the situation of Fd for Ft1, that is, the fitting operation of the situation that powder feeding roller 3 moves to developer roll 2 to powder feeding roller 3 and the spacing principle of position-limit mechanism 6 are further described.
In existing product, be all to adopt support or bearing to locate the axle head of powder feeding roller 3, position-limit mechanism 6 is not set.According to technology point of the present utility model, do not use support or bearing, notch 5 just need to be set, powder feeding roller 3 axle heads are arranged in powder storehouse from photosensitive drums 1 one sides of handle box, after developer roll 2 is also installed into powder storehouse, developer roll 2 will apply a power Fd to powder feeding roller 3, prevents that powder feeding roller 3 from deviating from from notch 5.But, under the effect of power Ft1, powder feeding roller 3 can move to notch 5 opening directions all the more, just there will be powder feeding roller 3 and developer roll 2 situation of extruding mutually, make powder feeding roller 3 reprint carbon dust amount on developer roll 2 unstable, affect the final printing effect of product, further also may occur the situation that the first idle pulley 9 and powder feeding roller driven wheel 8 are stuck, the serviceable life of directly reducing product.Position-limit mechanism 6 is arranged on a certain position in notch 5, can make notch 5 produce one and above-mentioned power Ft opposite effect power, weaken or the power of counteracting Ft, and then restriction powder feeding roller 3 continues to the outer movement of notch 5.
In order to improve the frictional dissipation between powder feeding roller 3 axle heads and notch 5, a wherein side or the both sides of the edge of above-mentioned notch 5 all arrange boss 11, above-mentioned boss 11 can play the effect of thickening notch 5, avoid causing notch 5 serious wear because powder feeding roller 3 and notch 5 relatively rotate for a long time, affect the serviceable life of handle box.
As shown in Figure 7, for powder feeding roller 3 is arranged on the schematic diagram on handle box, because one end of handle box has been provided with notch 5, therefore, the other end of handle box can be without the mounting structure of being arranged to again open type, and can be arranged to a mounting hole 12, to improve the stability after powder feeding roller 3 is installed, described mounting hole 12 can be circular hole, is preferably elliptical aperture, because powder feeding roller 3 is to tilt to insert in mounting hole 12, elliptical aperture can provide the axle head that more space facilitates powder feeding roller 3 to insert.
When installation, first one end of powder feeding roller 3 is inserted in mounting hole 12, its other end inserts from the peristome of notch 5 again, the aforementioned distance being arranged between the top of the position-limit mechanism 6 in notch 5 and an other side of notch 5 should be close with the diameter of powder feeding roller 3 axle heads as far as possible, or slightly little, insert when notch 5 with the axle head that makes powder feeding roller 3, can produce certain resistance, but be unlikely to make axle head to install.
