Abstract
A toner cartridge photosensitive drum positioning structure comprises a metal shaft. The metal shaft penetrates out of a central hole of a photosensitive drum large gear via the inside of a toner cartridge after penetrating through a photosensitive drum small gear, the diameter of the middle of the metal shaft is larger while the diameters of two end positions are smaller, and conical step structures are arranged at two ends of the metal shaft and respectively match with conical steps correspondingly arranged on a left lateral baffle plate and a right lateral baffle plate.
Description
Technical field
The utility model relates to a kind of both laser printer systems, is specially adapted to the location to the used photosensitive drum of selenium drum of printer.
Background technology
At present, the photosensitive drums locator meams of more known toner cartridges is: with the two ends that two short metal pivot pins insert photosensitive drums respectively, photosensitive drums is played a supporting role, pivot pin also plays the effect of conduction simultaneously.Two short metal pivot pins are processed together by the method for injection moulding with left side baffle plate, the right side baffle plate of toner cartridge respectively, synthesize one.
There is following shortcoming in its structure: 1) so have certain verticality and other foozle, increased difficulty and cost when making injection mold; 2) because the error that produces when adding the existence of the error of perpendicularity that produces man-hour and assembling, the center line that assembling is finished after, is difficult to guarantee two pivot pins point-blank, so the bigger coaxiality error of existence; 3) because left and right sides stub axle pin is designed to cantilever beam structure, the elasticity that moulding had so be easy to generate swing when work, influences the photosensitive drums job stability in addition; 4) owing to being to adopt two pivot pins, so when producing in enormous quantities, can influence production efficiency.
The utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of can improve the photosensitive drum of selenium drum job stability, and manufacturing process is simple, a kind of laser selenium drum photosensitive drums location structure that production efficiency is high.
The utility model for the technical scheme that solves its technical matters and adopt is: by utilize a metal shaft through photosensitive drums inside replace original about two short metal pivot pins, promptly metal shaft passes through the center pit of photosensitive drums inside from the photosensitive drums gear wheel after left end passes the photosensitive drums pinion wheel.Passing the back metal shaft contacts with sheet metal on the photosensitive drums pinion wheel.To bear pressure bigger because of the metal shaft centre position, so the centre position diameter is bigger, plays the supporting role to photosensitive drums.End positions is stressed less relatively, thereby diameter can be less relatively, to alleviate the weight of total.
In order to increase the anchorage force at two ends, metal shaft also can be designed to middle and all bigger structure of end positions diameter, and whole metal shaft like this is two ends and the bigger notch cuttype structure of mid diameter.
The two ends of metal shaft are designed to frustum of a cone stage structure, are equipped with the frustum of a cone screens that matches in the corresponding positions of left side baffle plate and right side baffle plate, the two ends of metal shaft respectively with left side baffle plate and right side baffle plate on corresponding frustum of a cone clamping matching.The left end of metal shaft exposes the left side baffle plate, plays the effect of conduction.
The beneficial effects of the utility model are that the coaxiality error that has produced when having eliminated two pivot pin cooperatings of original employing has been simplified manufacturing process, has reduced processing cost, can also effectively enhance productivity when producing in enormous quantities.

1. shells among the figure, 2. left side baffle plate, 3. metal shaft, 4. photosensitive drums, 4a. photosensitive drums pinion wheel, 4b. sheet metal, 4c. photosensitive drums gear wheel, 5. right side baffle plate.
Embodiment
In Fig. 1, photosensitive drums (4) is positioned at shell (1), and the photosensitive drums pinion wheel (4a) that metal shaft (3) is passed photosensitive drums (4) left side contacts with sheet metal (4b), passes the endoporus of photosensitive drums gear wheel (4c) at last.Left side baffle plate (2) is positioned at photosensitive drums pinion wheel (4a) end, and right side baffle plate (5) is positioned at photosensitive drums gear wheel (4c) end.Wherein metal shaft (3) runs through photosensitive drums (4), and corresponding frustum of a cone clamping matching is gone up with left side baffle plate (2) and right side baffle plate (5) respectively in the two ends of metal shaft (3).Left side baffle plate (2) and right side baffle plate (5) pass through screw retention together with shell (1).Left side baffle plate (2), right side baffle plate (5) and metal shaft (3) are formed simple beam structure jointly, play the supporting role to photosensitive drums (4).
As shown in Figure 2, the end of metal shaft (3) is designed to frustum of a cone stage structure, match with frustum of a cone screens on the left side baffle plate (2), between cooperation adopt the transition fit mode, metal shaft (3) and photosensitive drums (4) cooperate the employing gap fiting mode.The end face of metal shaft (3) exposes the surface of left side baffle plate (2), plays the effect of conduction.
As shown in Figure 4, in the middle of metal shaft (3) is designed to according to its distribution situation of bearing moment of flexure and all bigger notch cuttype structure of end positions diameter, can alleviate whole weight guaranteeing photosensitive drums (4) is played on the basis of safety supports.
During running, electric current passes through sheet metal (4b) again to photosensitive drums (4) charging through the two ends of metal shaft (3), and at this moment metal shaft (3) plays the effect of conduction.Printer driver photosensitive drums gear wheel (4c) and photosensitive drums pinion wheel (4a) rotatablely move photosensitive drums (4) generation simultaneously, metal shaft (3) produces relative rotation with photosensitive drums (4), metal shaft (3) relatively rotates with left side baffle plate (2) and right side baffle plate (5) nothing, and at this moment metal shaft (3) plays the effect of supporting photosensitive drums (4) rotation.
Claims (4)
