Abstract
The utility model discloses a toner cartridge, which has the advantages of simple structure, good performance and low cost. The toner cartridge comprises a cartridge body (1), and a toner bin (2), a development roller (3) and a toner-feeding roller which are arranged in the cartridge body (1), one end of the cartridge body (1) is provided with a gear assembly (4), a toner-discharging cutter (5) is also arranged in the cartridge body (1), and is contacted with the development roller, the toner-discharging cutter (5) is fixedly arranged in the cartridge body (1) by bolts (6), and the end of the cartridge body (1) is also provided with a conductive toner-discharging cutter strip (7), which is contacted with the toner-discharging cutter (5). The utility model can be widely applied in the field of laser printer consumables.
Description
Technical field
The utility model relates to laser printing consumptive material field, relates in particular to a kind of cartridge.
Background technology
Fast development along with science and technology, laser printing technology also obtains fast development, and more and more be tending towards ripe, the printer material consumption series of products are brought in constant renewal in progress thereupon, cartridge as one of main printing consumables, its technology, performance whether superior directly influences printing effect, quality and prints cost; Cartridge develops into present stage, and all types of cartridges are structurally roughly the same, and principle of work is basically identical also; Cartridge commonly used at present has monoblock type cartridge and split type cartridge, the main body that so-called split type cartridge is a cartridge is divided into the two large divisions who cooperatively interacts, wherein a part is provided with parts such as powder storehouse, powder feeding roller, developer roll, another part then is provided with parts such as photosensitive drums, clearer, split type cartridge realizes that the drum powder separates, and the isolation of components of rapid wear is comparatively come out, during damage, change impaired part and get final product, thereby reduce use cost; The powder delivery cutter is arranged on one of parts of the cartridge of being with the powder storehouse, the powder delivery cutter contacts with developer roll, the thickness of carbon dust layer on the control developer roll, and assistance carbon dust frictional electrification, in cartridge, very high to the matching requirements of powder delivery cutter, evenly control the carbon dust layer thickness and effectively make carbon dust charged guaranteeing, if the undesirable print quality problems such as look shallow, stain, black line that then cause on printed product easily of assembling, even the powder situation appears leaking; In the existing carbon powder cartridge for laser printer, majority utilizes the elastic force pressure of powder delivery cutter spring to act on the powder delivery cutter, the powder delivery cutter is contacted with developer roll, the cartridge of this structure is unsatisfactory in actual applications,, described powder delivery cutter spring produces the effect that contacts that deformation influences powder delivery cutter and developer roll thereby being subjected to the influence of external force easily, therefore, utilize described powder delivery cutter spring to provide elastic force pressure to the powder delivery cutter, can not ensure effectively that powder delivery cutter and developer roll can be straight, contact equably, thereby be difficult to guarantee that the thickness of evenly controlling the carbon dust layer directly influences printing effect and print quality; And in order to prevent the dislocation of powder delivery cutter spring or to eject the cartridge outside, usually need in cartridge, add spring bumper cover is set, cover described powder delivery cutter spring, prevent its ejection, this measure has strengthened the complexity of cartridge structure undoubtedly, and increased production cost, in addition, in the cartridge of this structure, only utilize the elasticity of powder delivery cutter conducting strip self, realize contacting and conduction of powder delivery cutter conducting strip and powder delivery cutter, thereby very easily powder delivery cutter conducting strip is become flexible with the generation that contacts of powder delivery cutter because of the influence of extraneous factor, thereby cause conduction bad, further influence printing effect and quality.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of simple structure, functional, lower-cost cartridge are provided.
The technical scheme that the utility model adopted is: the utility model comprises box body, described box body inside is provided with powder storehouse, developer roll, powder feeding roller, one end of described box body is provided with gear assembly, described box body inside also is provided with the powder delivery cutter, described powder delivery cutter contacts with described developer roll, described powder delivery cutter is installed in the described box body by screw retention, and the end of described box body also is provided with powder delivery cutter conducting strip, the cooperation that contacts with described powder delivery cutter of described powder delivery cutter conducting strip.
Optimize, described powder delivery cutter conducting strip is by the fixing contact matching of described screw and described powder delivery cutter.
The beneficial effects of the utility model are: in the utility model, described powder delivery cutter is installed in the described box body by screw retention, owing to realize fixed installation by described screw between described powder delivery cutter and the described box body, therefore, can not produce displacement between described powder delivery cutter and the described developer roll, remain fixing, contact uniformly, when cartridge uses or is mobile, can not impact described powder delivery cutter, can keep straight between described powder delivery cutter and the developer roll, contact equably, thereby make the described powder delivery cutter can be, thereby ensure good printing effect and good print quality its fixed thickness of carbon dust layer retentive control.The utility model has been avoided fixedly existing defective during the powder delivery cutter of use powder delivery cutter spring, and need not to add spring bumper cover is set, thereby effectively simplifies and optimized the cartridge structure, and reaches the purpose that reduces production costs.
In the utility model, described powder delivery cutter conducting strip fixedly contacts with described powder delivery cutter by described screw, can guarantee tight contact the between powder delivery cutter conducting strip and the powder delivery cutter thus, ensures its excellent conducting performance, thereby make carbon dust charged effectively, improve print quality.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises box body 1, described box body 1 inside is provided with powder storehouse 2, developer roll 3, clearer, one end of described box body 1 is provided with gear assembly 4, described box body 1 inside also is provided with powder delivery cutter 5, described powder delivery cutter 5 contacts with described developer roll, described powder delivery cutter 5 is fixedly installed in the described box body 1 by screw 6, guarantee thus can not produce displacement between described powder delivery cutter 5 and the described developer roll, remain fixing, contact uniformly, the end of described box body 1 also is provided with powder delivery cutter conducting strip 7, described powder delivery cutter conducting strip 7 is by the fixing contact matching of described screw 6 and described powder delivery cutter 5, during assembling, described screw 6 is penetrated the pilot hole that described powder delivery cutter conducting strip 7 is offered, be screwed into the screw hole that described powder delivery cutter 5 is provided with again.At least utilize two pieces of screws 6 described powder delivery cutter 5 to be fixedly mounted on the described box body 1 at the both ends of described powder delivery cutter 5.In view of the production technology of cartridge is quite ripe, NM other features of the utility model are same as the prior art, repeat no more herein.
The utility model can be widely used in laser printer consumptive material field.
