Abstract
The utility model discloses seperated drum to exempt from wear structure cartridge, including seperated drum, the fission drum upper end is equipped with photosensitive drums, it is provided with spring mounting groove on the downside of its seperated drum, and spring mounting groove is internally provided with spring, spring jacking block is connected on the upside of the spring, and be equipped with photosensitive drums on the upside of spring jacking block, developer roll is installed on the upside of the photosensitive drums, and developer roll both sides are equipped with roller set.Fission drum improvement set axis cartridge, under compared with existing cartridge, developer roll both sides are symmetrically installed with roller set, its developer roll runs through roller set, and the material of roller set is rigid aluminium, the roller set of rigid aluminium material can fix the distance between photosensitive drums and developer roll, the distance between developer roll and photosensitive drums are 0.5 1mm, photosensitive drums and developer roll cooperating can preferably be made in this way, spring force low precision is avoided to influence printing effect, the diameter of spring is equal with the width of spring mounting groove, and spring is made more to stablize.
Description
Technical field
The utility model is related to cartridge technical field, specially seperated drum exempts from wear structure cartridge.
Background technology
General printer drum cartridge makes developer roll press cooperating with photosensitive drums by spring force, but
Elastic force low precision uses long easy both sides unbalance stress so that developer roll and photosensitive drums pressing cooperation are bad, influence to print matter
Amount.
Utility model content
The purpose of this utility model is to provide seperated drum to exempt from wear structure cartridge, to solve in above-mentioned background technology
It is proposed that general printer drum cartridge makes developer roll press cooperating, but elastic force with photosensitive drums by spring force
Low precision uses long easy both sides unbalance stress so that developer roll and photosensitive drums pressing cooperation are bad, influence print quality
Problem.
To achieve the above object, the utility model provides the following technical solutions：It is a kind of fission drum exempt from wear structure carbon dust
Box, including seperated drum, the fission drum upper end are equipped with photosensitive drums, spring mounting groove are provided on the downside of seperated drum,
And spring mounting groove is internally provided with spring, spring jacking block is connected on the upside of the spring, and thoughts are installed on the upside of spring jacking block
Light rouses, and is equipped with developer roll on the upside of the photosensitive drums, and developer roll both sides are equipped with roller set.
Preferably, the developer roll both sides are symmetrically installed with roller set, and developer roll runs through roller set, and the material of roller set is rigid
Property aluminium.
Preferably, the distance between the developer roll and photosensitive drums are 0.5-1mm.
Preferably, the diameter of the spring and the width of spring mounting groove are equal.
Compared with prior art, the utility model has the beneficial effects that：The fission drum is and existing with improving set axis cartridge
Under some cartridges compare, developer roll both sides are symmetrically installed with roller set, and developer roll runs through roller set, and the material of roller set is
Rigid aluminium, rigid aluminium material roller set can fix the distance between photosensitive drums and developer roll, between developer roll and photosensitive drums away from
It from for 0.5-1mm, can preferably make photosensitive drums and developer roll cooperating in this way, spring force low precision is avoided to influence printing effect
Fruit, the diameter of spring is equal with the width of spring mounting groove, and spring is made more to stablize.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model developer roll and roller casing connecting structure schematic diagram；
Fig. 3 is enlarged structure schematic diagram at A in the utility model Fig. 1.
In figure：1, developer roll, 2, roller set, 3, seperated drum, 4, photosensitive drums, 5, spring mounting groove, 6, spring jacking block, 7, bullet
Spring.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
- 2 are please referred to Fig.1, the utility model provides a kind of technical solution：It is a kind of fission drum exempt from wear structure cartridge,
Including seperated drum 3,3 upper end of seperated drum is equipped with photosensitive drums 4, and 3 downside of seperated drum is provided with spring mounting groove 5, and
Spring mounting groove 5 is internally provided with spring 7, and 7 upside of spring is connected with spring jacking block 6, and is equipped on the upside of spring jacking block 6 photosensitive
The diameter of drum 4, spring 7 is equal with the width of spring mounting groove 5, and spring 7 is made more to stablize, and 4 upside of photosensitive drums is equipped with development
Roller 1, and 1 both sides of developer roll are equipped with roller set 2,1 both sides of developer roll are symmetrically installed with roller set 2, and developer roll 1 runs through roller set 2, and
The material of roller set 2 is rigid aluminium, and the roller set 2 of rigid aluminium material can fix the distance between photosensitive drums 4 and developer roll 1, developer roll 1
The distance between photosensitive drums 4 are 0.5-1mm, can preferably make photosensitive drums 4 and 1 cooperating of developer roll in this way, avoid spring 7
Elastic force low precision influences printing effect.
Operation principle：When using the fission drum with set axis cartridge is improved, first the structure of the device is carried out simple
Understanding, spring 7 is squeezed first, photosensitive drums 4 are installed with seperated drum 3, developer roll 1 is then installed to roller
In set 2, roller set 2 ensures that the distance between developer roll 1 and photosensitive drums 4 are 0.5-1mm, installation is completed, when 7 usage time mistake of spring
When long, uneven is become for the pressing dynamics of developer roll 1 and photosensitive drums 4, the roller set 2 of rigid aluminium material limits developer roll at this time
The distance between 1 and photosensitive drums 4, to ensure that the quality of printing, here it is fission drum improvement set axis cartridges
Operation principle.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is appreciated that can these embodiments be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
