Description
Technical field
Printer toner cartridge technical field is the utility model is related to, more particularly to a kind of developer roll of toner cartridge.
Background technology
The aluminum pipe outer surface of current developer roll is provided with conductive plastic layer, the conductive plastic layer, is generally filled by mould
The mode of note is arranged on the outer surface of aluminum pipe, complex manufacturing, and cost is high, does not bear dirty, non-refractory, short life,
, it is necessary to grind off the plastic layer of its outer surface when being recycled to aluminum pipe, process is relatively complicated, is unfavorable for environmental protection.
Accordingly, it is desirable to provide a kind of developer roll of toner cartridge is to solve above-mentioned technical problem.
Utility model content
The utility model is replaced using conductive wear-resisting glue-line mainly solving the technical problems that provide a kind of developer roll of toner cartridge
Traditional conductive rubber set is changed, production difficulty and cost is reduced, high temperature resistant, bears dirty, long lifespan, be easy to recycle, there is ring
The effect of guarantor.
In order to solve the above technical problems, the technical scheme that the utility model uses is to provide a kind of development of toner cartridge
Roller, including aluminum pipe, aluminum pipe one end set conductive head, the other end to set insulation gear end connector, and aluminum tube surfaces are coated with one layer
Conductive wear-resisting glue-line.
It is preferred that the aluminum pipe end set where the insulation gear end connector has what is gradually tightened up to aluminum pipe central axis
Three-level step, the one-level step that the oriented aluminum pipe central axis of end set of the aluminum pipe where the conductive head is tightened up, and it is described
The external diameter and the insulation gear of the one-level step tightened up to aluminum pipe central axis of the end set of aluminum pipe where conductive head
Hold the outer of the internal layer step in the gradual three-level step tightened up to aluminum pipe central axis of the aluminum pipe end set where connector
Footpath is equal.
It is preferred that the length of the developer roll of the toner cartridge is 254.9mm ± 0.1mm, the thickness of conductive wear-resisting glue-line for 0.2~
1mm。
It is preferred that external diameter is 10.99mm~11.02mm in the middle part of the aluminum pipe.
The beneficial effects of the utility model are：A kind of developer roll of toner cartridge provided by the utility model is wear-resisting using conduction
Glue-line replaces traditional conductive resistance to rubber sleeve, reduces production difficulty and cost, high temperature resistant, bears dirty, long lifespan, is easy to recovery profit
With the effect with environmental protection.
Brief description of the drawings
Fig. 1 is a kind of structural representation of a preferred embodiment of the developer roll of toner cartridge of the present utility model.
B is transversal in Fig. 1.
Embodiment
The technical solution of the utility model is described in detail with reference to diagram.
The developer roll of toner cartridge as shown in Figure 1, including aluminum pipe 21, the one end of aluminum pipe 21 set conductive head 22, the other end to set
The gear end that insulate connector 23, the surface spraying of aluminum pipe 21 has one layer of conductive wear-resisting glue-line 24.
In the utility model, traditional conductive rubber set is instead of with conductive wear-resisting glue-line 24, due to the conduction in spraying
Wear-resisting glue-line 24 can be closely bonded with the surface of aluminum pipe 21, and for this conductive layer than traditional conductive rubber set, what can be done is thin
Some, in the case of having predetermined outer diameter requirement to the external diameter of whole developer roll, aluminum pipe 21 can be increased by reducing conductive layer
External diameter.This brings very big convenience to the production and assembling of whole developer roll.And when withdrawing utilization, it is only necessary to by conductive layer
Grind off i.e. reusable, and traditional conductive rubber set is the surface that aluminum pipe is bonded in using viscose, withdraw utilize when,
Viscose is difficult to grind off, and this brings very big difficulty to recycling.
Please referring further to Fig. 1, it is preferable that the end set of aluminum pipe 21 where the insulation gear end connector 23 has gradually
The three-level step 25 tightened up to the central axis of aluminum pipe 21, the oriented aluminum pipe 21 of end set of the aluminum pipe 21 where the conductive head 22
The one-level step 26 that central axis is tightened up, and the oriented central shaft of aluminum pipe 21 of end set of the aluminum pipe 21 where the conductive head 22
The end set of aluminum pipe 21 where the external diameter for the one-level step 26 that line is tightened up and the insulation gear end connector 23 have gradually to
The external diameter of internal layer step in the three-level step 25 that the central axis of aluminum pipe 21 is tightened up is equal, be designed so that external diameter it is equal one
The end set of aluminum pipe 21 described in the external diameter of level step 26 where insulation gear end connector 23 has gradual to the center of aluminum pipe 21
Protective case can be arranged on internal layer step in the three-level step 25 that axis is tightened up, the thickness of the protective case is needed according to conductive resistance to
The thickness of mill glue-line 24 is flexibly selected, and protective case can prevent the end wear of conductive wear-resisting glue-line 24.
In a preferred embodiment of the present utility model, the length of the developer roll of the toner cartridge for 254.9mm ±
0.1mm, the thickness of conductive wear-resisting glue-line 24 is 0.2~1mm.Further, it is preferable that the middle part external diameter of aluminum pipe 21 is
10.99mm~11.02mm.
The characteristics of developer roll of toner cartridge of the present utility model, is：Aluminum pipe outer surface is injected with one layer of conductive wear-resisting glue-line,
More traditional conductive rubber set is compared using conductive wear-resisting glue-line, producting process difficulty and cost reduce, and are easy to recovery profit
With, beneficial to environmental protection, and bear dirty, long lifespan.
Embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, it is every
The equivalent structure made using the utility model specification and accompanying drawing content, or directly or indirectly it is used in other related technologies
Field, similarly it is included in scope of patent protection of the present utility model.
