Description
Technical field
The utility model relates to a kind of cartridge structure.
Background technology
The cartridge of laser type printer mainly includes the parts such as toner, waste powder hopper, powder feeding roller, developer roll, photosensitive drums, charging roller, powder outlet cutter and cleaning doctor, the effect of developer roll is the absorption carbon dust, make it charged, and be sent to photosensitive drum surface to print work.Yet in use, we usually can find not to be to lack in the situation of carbon dust, still have to print blank situation, and by researching and analysing, whether the contact that main cause must be attributed between developer roll and the photosensitive drums is good.Generally speaking, the developer roll of printer is pressed against (maintenance certain interval) on the photosensitive drums by check lock lever, because during operating personnel's rotation lock bar, move too fast too quickly, cause easily the check lock lever torsional deformation, can not lock developer, the excesssive gap of developer roll and photosensitive drums, carbon dust can not jump on the photosensitive drums, has also just occurred printing blank.Moreover, because to a certain degree wearing and tearing and consumption can occur first for developer roll and the long-time use of photosensitive drums, also can cause the gap of developer roll and photosensitive drums to increase gradually, affect print quality.
In addition, cartridge under the prior art, such as Fig. 1, Fig. 2, shown in Figure 3, toner 1 and waste powder hopper 2 are connected, and developer roll 3 and photosensitive drums 4 all are arranged between toner and the waste powder hopper, their position is determined along with the setting of toner and waste powder hopper both sides end cap, be shaped in case produce, the position relationship of developer roll and photosensitive drums just can't be adjusted, if the generation said circumstances can only be dismantled cartridge and repair or replace, and could improve the print quality of printer, do like this and not only improved the printing cost, also increased many unnecessary work troubles.And with toner and waste powder hopper Integral design, because cartridge structure relative complex is offered grinding tool and seemed very loaded down with trivial details, also very inconvenient when the parts such as installation developer roll, photosensitive drums and powder outlet cutter, producting process difficulty is high, is unfavorable for enhancing productivity.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provides a kind of and reduce producting process difficulty, is convenient to production and processing, enhances productivity and improves the cartridge structure of print quality.
The technical scheme that the utility model adopts is: the utility model is comprised toner, waste powder hopper, powder feeding roller, developer roll, photosensitive drums and charging roller, described developer roll is arranged at described toner sidepiece, described photosensitive drums is arranged at described waste powder hopper sidepiece and remains that described developer roll contacts cooperation with described photosensitive drums, the bottom of described toner and the bottom of described waste powder hopper are rotatably assorted, and the top of described toner and the top of waste powder hopper are connected by elastic device.
Preferably, the middle part of described toner adopts pin to be connected with the middle part of described waste powder hopper.
Preferably, described elastic device is made as spring.
Preferably, described toner and waste powder hopper are equipped with the joint pin adaptive with described spring, and the two ends of described spring are fixedly connected with described joint pin.
Preferably, described elastic device is made as extension spring.
Preferably, described elastic device is made as torsion spring.
The beneficial effects of the utility model are: because the utility model comprises toner, waste powder hopper, powder feeding roller, developer roll, photosensitive drums and charging roller, described developer roll is arranged at described toner sidepiece, described photosensitive drums is arranged at described waste powder hopper sidepiece and remains that described developer roll contacts cooperation with described photosensitive drums, the bottom of described toner and the bottom of described waste powder hopper are rotatably assorted, and the top of described toner and the top of waste powder hopper are connected by elastic device; Be assembled together again by the described toner of powder box and described waste powder hopper are separately produced, reduce production and processing and technology difficulty, when the assembling cartridge, the parts such as powder feeding roller, developer roll, photosensitive drums and charging roller can be installed easily, enhance productivity.
In addition, described developer roll is arranged on the described toner, described photosensitive drums is arranged on the described waste powder hopper, and described toner and described waste powder hopper be rotationally connected by an end, the mode that the other end adopts elastic device to connect, under the effect of described elastic device, join domain between described toner and the described waste powder hopper can be regulated, and then can regulate the contact gap of described developer roll and described photosensitive drums, particularly work as described developer roll and described photosensitive drums and do not reach technical requirement because of the Design Orientation error, or be that described developer roll and described photosensitive drums occur in the situation of to a certain degree loss, the contact gap of developer roll and photosensitive drums can be adjusted in the suitable scope by described spring assembly, guarantee good print quality.

Embodiment
Such as Fig. 4, Fig. 5, Fig. 6, shown in Figure 7, the utility model relates to a kind of cartridge structure, it comprises toner 5, waste powder hopper 6, powder feeding roller, developer roll 7, photosensitive drums 8 and charging roller, described developer roll 7 is arranged at described toner 5 sidepieces, described photosensitive drums 8 is arranged at described waste powder hopper 6 sidepieces, the bottom of the bottom of described toner 5 and described waste powder hopper 6 is rotatably assorted, and specifically the bottom of described toner 5 and the bottom of described waste powder hopper 6 can be connected through the hinge.The top of the top of described toner 5 and waste powder hopper 6 is connected by elastic device, described elastic device can be spring 9, extension spring or torsion spring, and it is general preferred with spring 9, described toner 5 and waste powder hopper 6 are equipped with the joint pin adaptive with described spring 9, and the two ends of described spring 9 all are fixedly connected with described joint pin.Described toner 5 be connected waste powder hopper 6 by an end is rotationally connected, the other end adopts elastic device to connect mode, under the effect of described elastic device, join domain between described toner 5 and the described waste powder hopper 6 can be regulated, and then can regulate the contact gap of described developer roll 7 and described photosensitive drums 8.The middle part of described toner 5 adopts pin 10 to be connected with the middle part of described waste powder hopper 6, described pin 10 is used for fixing the connection status of current described toner 5 and waste powder hopper 6, prevents that described toner 5 and waste powder hopper 6 from loosening phenomenon in use occuring.The utility model can effectively be avoided greatly having improved print quality because of the excessive or too small print quality problem that affects of the contact gap between developer roll and the photosensitive drums.
The utility model is widely used in the cartridge field.
