Description
Technical field
The utility model relates to a kind of printer image forming device, more specifically is meant a kind of developer roll that is installed in printer.
Background technology
The effect of the developer roll in the printer is the absorption carbon dust, and outside transmission of this carbon dust produced visible image at last on paper.This shows that developer roll has irreplaceable effect in printing, make printer have better printing effect to become the major issue of industry and consumer's care and how to improve existing developer roll.
As Fig. 1 to 2 is common in the market developer roll, it mainly comprises, roll body 10A termination 20A and transmission gear 30A, wherein, this termination 20A is the two ends that are installed in this roll body 10A respectively, and this transmission gear 30A is provided in a side of this one of them termination 20A's, and can drive this termination and this roll body 10A rotation.
This roll body 10A has inner chamber 11A in it, and this inner chamber is that further this roll body adopts aluminum pipe to be made, and is coated with one deck conductive layer on its surface through the two ends of this roll body 10A.
This termination 20A is be installed in this roll body 10A respectively two disconnected, and its size cooperates the size setting of this roll body 10A to form, and is provided with in it and inserts chamber 21A.
This transmission gear 30A is provided in a side of on this one of them the termination 20A, it includes, web member 31A and elastic arm 32A, wherein, this elastic arm is provided in a side of on this web member 31A, and further, this web member 31A is plugged in the slotting chamber 21A of this termination 20A, this elastic arm is fastened in this slotting chamber 21A, and this transmission gear 30A can firmly be connected with this termination 20A.
In addition, also be provided with catch 40A, make this developer roll when in use, rotate more smooth and easy at another termination 21A relative with this transmission gear 30A.
By above-mentioned structure, when in use, because this roll body is to adopt the aluminum pipe manufacturing to form, this developer roll can be conducted electricity when in use, and adsorb carbon dust, and outside transmission of this carbon dust produced visible image at last on paper.And, on certain degree, alleviate the weight of whole developer roll owing to adopt the aluminum pipe manufacturing to form.But also there are many shortcomings in above-mentioned developer roll in concrete use, be described below respectively now.
At first, the roll body of this developer roll is to adopt the aluminum pipe manufacturing to form, and is coated with one deck conductive layer on its surface, in concrete the use, in case this conductive layer is worn the effect that will have influence on developer roll absorption carbon dust, and then causes the printing effect mass deviation.This is one of major defect of existing developer roll.
Secondly, because the restriction of aforesaid developer roll material and structure, existing developer roll when in use, conductive effect is unsatisfactory, in other words, existing developer roll is when the absorption carbon dust, and its absorption affinity is obviously not strong, and cause when printing, some image can not completely print.This is the another shortcoming of existing developer roll.
Once more, because the restriction of its roll body material in concrete the use, can generate heat and then produce exhaust gases ambient air quality, and this is a shortcoming again of existing developer roll.
At last, just can make it when in use, give play to the due effect of developer roll because of its roll body surface need be coated with conductive coating, but,, that is to say because of its roll body surface spraying conductive coating is not that part is easy to operation, the operation of its manufacturing is too loaded down with trivial details, makes troubles to production.This is the another shortcoming of existing developer roll.
Summary of the invention
The utility model provides a kind of developer roll, and its roll body adopts the conductive polyurethane material to make, and makes to the utlity model has stronger absorption carbon dust ability, and then makes printing effect quality height, and this is one of fundamental purpose of utility model.
The utility model provides a kind of developer roll, because its roll body adopts the conductive polyurethane material to make, makes roll body be difficult for being worn, and then prolongs serviceable life of the present utility model.This is an another purpose of the present utility model.
For achieving the above object, the technical solution adopted in the utility model is: a kind of developer roll, and it comprises, roll body, termination and iron core, wherein, this iron core is arranged in this roll body, and this termination is the two ends that are installed in this roll body respectively.
This roll body has cavity in it, and this cavity is through the two ends of this roll body.Further, this roll body is to adopt a kind of material nonmetal and that electric conductivity is good to make, such as: conductive polyurethane material etc.This polyurethane material is that the polyvalent alcohol of degree of unsaturation and one or more polyisocyanates produce and give the conductive polyurethane composition that agent is mixed and made into ionic conduction type again after cross-linking reaction forms urethane resin,
This termination is the two ends that are installed in this roll body respectively, and it has inner chamber, and the size of this inner chamber is set to more smaller than the size of this roll body,
This iron core is arranged in the cavity of this roll body, and is to be connected with the inner chamber of this termination, and its size forms according to the size setting of the inner chamber of this termination,
Further, a termination of this iron core is provided with connecting key, and by this connecting key, this iron core is connected with a transmission gear, and this transmission gear has connecting hole and driving cog, and wherein, this driving cog is arranged on the outside surface of this transmission gear.And make this rod body of the rotatable drive of this transmission gear, termination and iron core rotation by such structural design.
The beneficial effects of the utility model are: the utility model provides a kind of developer roll, because its roll body adopts the conductive polyurethane material to make, make roll body be difficult for being worn, and then prolong serviceable life of the present utility model, make this roll body have the ability of stronger absorption carbon dust simultaneously.
