Description
Technical field
The present invention relates to a kind of handle box of laser printer, particularly relate to the contactless handle box that has improved minimum clearance governor motion between photosensitive drums and developer roll.
Background technology
Electrophotographic image forming forming device such as laser printer, that a kind of electrofax principle of utilizing is formed at the equipment on medium such as paper to image, its handle box generally comprises: form the photosensitive drums of electrostatic latent image thereon, and provide developer on photosensitive drums with the developer roll of this electrostatic latent image that develops.
Whether separated from one another according to photosensitive drums and developer roll, there is a minimum clearance between the two, i.e. distance between the two axial connecting line and working surface intersection point, handle box can be divided into contact handle box and contactless handle box.
In the contact handle box, the work side face of photosensitive drums and developer roll contacts with each other, namely both are tangent from transverse section, laser printer applies DC offset voltage to developer roll, due to the voltage difference between photosensitive drums and developer roll, developer is transferred to photosensitive drums from developer roll, and this visualization way is called contact type developing.
In contactless handle box, photosensitive drums and developer roll have the minimum clearance of about 15-36 μ m to each other, in order to realize developing, need to developer roll, to apply DC offset voltage and AC bias voltage simultaneously, make with electrical developer particle, from developer roll, to jump to photosensitive drums with being magnetic, this visualization way is called contactless development, also claims great-jump-forward to develop.
Contactless handle box version the earliest is that the two ends of developer roll and photosensitive drums are bearing in respectively in the axis hole on handle box box body two relative side; Because the volume of handle box box body is larger, guarantee the accurate control of diaxon pitch of holes, not only high to the processing request of mould, but also exist the unmanageable problem of injection moulding shrink.
For addressing the above problem, in order to control better minimum clearance, be at the two ends of developer roll, to be respectively equipped with the axle sleeve of external diameter greater than developer roll working surface external diameter at present, this axle sleeve contacts with two end surfaces of photosensitive drums, thereby makes between developer roll and photosensitive drums to form and keep minimum clearance; And this technical scheme is very high to the requirement on machining accuracy of axle sleeve, and mounting process complexity, poor controllability and cost are high.
Summary of the invention
Fundamental purpose of the present invention is to provide the contactless handle box that a kind of cost is low, controllability is good.
For achieving the above object, the present invention also provides a kind of handle box, comprises box body and is positioned at the first end cap of box body one end and the second end cap of the other end, is rotatably installed in photosensitive drums and developer roll in box body.The two ends of developer roll are bearing in respectively in the first axis hole and the Triaxial hole on the second end cap that first end covers.The two ends of photosensitive drums are bearing in respectively in the second axis hole and the 4th axis hole on the second end cap that first end covers.Between the work side face of the work side face of developer roll and photosensitive drums, be formed with minimum clearance.
In this technical scheme, developer roll guarantees by the axis hole spacing on the less two end cap of the relative box body of volume with the location, position of photosensitive drums and the accurate control of minimum clearance, because the end cap volume is little, on mould, the diaxon pitch of holes is convenient to control, the injection moulding also less that shrinks, develop to the requirement of handle box structure thereby meet great-jump-forward.Compared with prior art, under equal effectively development working area condition, the developer roll of required formation and the workplace of photosensitive drums are less, save material and reduce costs; The present invention can also save two necessary spare and accessory parts axle sleeves that requirement on machining accuracy is high, makes the handle box structure simpler, simplifies mounting process, when improving efficiency of assembling, improves the quality of product, and cost is lower, and cost performance is higher.
A concrete scheme is by modes such as quadric injection mould, interference fit, to be fixed with respectively the first axle sleeve, the second axle sleeve, the 3rd axle sleeve and the 4th axle sleeve on the first axis hole, the second axis hole, Triaxial hole and the 4th axis hole.The two ends of developer roll are bearing in respectively in the axis hole of the first axle sleeve and the 3rd axle sleeve.The two ends of photosensitive drums are bearing in respectively in the axis hole of the second axle sleeve and the 4th axle sleeve.Compared with prior art, under equal effectively development working area condition, the developer roll of required formation and the workplace of photosensitive drums are less, save material and reduce costs.
The present invention also provides another kind of handle box, comprises box body and is positioned at the first end cap of box body one end and the second end cap of the other end, is rotatably installed in photosensitive drums and developer roll in box body.One end of developer roll is provided with an axle sleeve, and the external diameter of axle sleeve is greater than the external diameter of the work side face of developer roll, and the periphery of axle sleeve contacts with the surface of photosensitive drums.The other end of developer roll is bearing in the Triaxial hole on the second end cap.In photosensitive drums four axis hole of an end bearing on the second end cap corresponding with the other end of developer roll.
Visible by above scheme, only need an axle sleeve just can realize the accurate control of the minimum clearance of the location of developer roll and photosensitive drums position and an end, the minimum clearance of the other end guarantees by the axis hole spacing on the less end cap of the relative box body of volume, because volume is little, on mould, the diaxon pitch of holes is convenient to control, the injection moulding also less that shrinks, develop to the requirement of handle box structure thereby meet great-jump-forward.Compared with prior art, under equal effectively development working area condition, the developer roll of formation required for the present invention and the workplace of photosensitive drums are less, save material and reduce costs; The present invention can also save a necessary spare and accessory parts axle sleeve that requirement on machining accuracy is high, makes the handle box structure relatively simple, and mounting process is simplified, and when improving efficiency of assembling, has improved the quality of product, makes cost lower, and cost performance is higher.
A concrete scheme is by modes such as quadric injection mould, interference fit, to be fixed with respectively the 3rd axle sleeve and the 4th axle sleeve on Triaxial hole and the 4th axis hole.The other end of developer roll is bearing in the axis hole of the 3rd axle sleeve.A photosensitive drums end bearing corresponding with the other end of developer roll is in the axis hole of the 4th axle sleeve.
Another concrete scheme is that the sleeve outer circle face contacts with the work side face surface of photosensitive drums.
Another concrete scheme is that the sleeve outer circle face contacts with the axle surface of photosensitive drums.
