Technical field
The present invention is a kind of structure-improved of duplicating machine, particularly relates to the magnetic roller structure-improved of duplicating machine.
Background technology
At present; The duplicating machine of medium and small model is because all, and so the for example compactedness of duplicating machine design and cost etc. are when duplicating; Might exist in certain condition with the autotype image on the both sides of its page orientation and to bite; Specifically, exactly light to being beyond recognition, thereby might cause a series of copy quality problems near the local autotype picture drop-out of some millimeters of two edges or concentration.
Trace it to its cause, duplicating machine has a very important core part on the magnetic roller in developing device, and the structure of magnetic roller is made up of its inner magnetic magnetic pole plug and outside metallic sheath; The outside surface of metallic sheath bucket generally is shaped by lathe finishing pole, and surface smoothness is better, and purpose is to strengthen to show the seal effect; The magnetic roller is packed into behind the apparent seal cabin; With many apparent printing mechanism part high speed rotating, utilize the magnetic attraction ink powder, transfer to the optical conductor surface and form visual image.Simultaneously, in order to prevent that ink powder is escaped with magnetic roller high speed rotating in the apparent seal cabin, disperse to out of my cabin, it is inner to pollute duplicating machine, and the plane of generally adopting the wool felt interference fit to protect cover barrel two ends root is sealed.
The defective of prior art is; Wool fibre on the wool felt and this plane produce violent friction, and magnetic roller two ends do not stay trickle machining screw stria mark, the threaded line that stays after the machine work unavoidably after the lathe machine work; Wool fibre moves to lentamente under the effect of the axial expulsive force that threaded line produced of rotation and shows in the seal cabin; Mix and stir with ink powder in the cabin, like this, just stopped that ink powder shows the seal path in the cabin; Because the barrier present position is the left magnetic roller end, so just can see on copy paper that the image on the both sides of page orientation is bitten or very light.Like this, just directly influence copy quality.Generally, show seal cabin and magnetic roller two end in contact parts, additional wool felt contacts, rubs not severe with the magnetic roller in new; But in use for some time; Wool felt has fluffed, and wool fibre inwardly is involved in from magnetic roller two ends gradually, and the quality of both sides is duplicated in influence.Trickle observation and research and since lathe from magnetic roller one end to other end turning, therefore whole magnetic forms the threaded line of a sense of rotation; So structure cause magnetic roller two ends wool fiber one end along with threaded line is involved in to showing seal shell inboard, cabin; The other end then rolls out towards showing the shell outside, seal cabin, the paper that runs off, after a time; Wherein the fog-level of a side is serious, and so phenomenon and defective are that the prior art duplicating machine is inevitable.
Abroad, in order to guarantee to duplicate quality, be 20,000 of duplicating the serviceable life that generally limits the magnetic roller, and we are domestic, and in order to economize on resources, generally limiting the life-span is 40,000, so, causes the duplicating poor quality in later stage.
To duplicate quality in order improving abroad, also to have and adopt the left magnetic roller two ends to be nested with the scheme of magnetic seal circle again, but improved cost first, also higher to the configuration requirement of magnetic seal circle in addition.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, a kind of magnetic roll structure of duplicating machine is provided, avoid and eliminate when duplicating machine and use a period of time, during the wool felt fluffing, wool fiber is not involved in the defective that shows in the shell of seal cabin.
The object of the invention is solved by following technical scheme:
A kind of magnetic roll structure of duplicating machine is characterized in that:
The two ends of magnetic roller have the threaded line of opposite rotation direction respectively,
The threaded line sense of rotation of each end is: make and will extend to magnetic roller outer end with magnetic roller sense of rotation threaded line.
Adopt the present technique scheme, even the wool felt that contacts with magnetic roll end friction fluffing, wool fiber has dropped; Will be with magnetic roller sense of rotation threaded line to the threaded line of magnetic roller outer end extension; Be with wool fiber to transfer outward, can not getting into to show and print in the shell of cabin, can not influence the quality of duplicating.
Threaded line is divided into left-handed or dextrorotation, both along with the axial rise trend of an oriented end when circumference rotates.The two ends of prior art magnetic roller or all be left-handed perhaps all are dextrorotation, and adopt the present invention, then two ends wherein an end be left-handed; One end is dextrorotation, and which end is for left-handed actually, and which end is dextrorotation; Be to decide, reach that the threaded line at two ends rises to the outside, two ends respectively along with the rotation on the threaded line left magnetic roller according to the sense of rotation of magnetic roller; The wool fiber that drops can guarantee can not block the paper of duplicating along the threaded line at two ends respectively to the outer side shifting at two ends, guarantees to duplicate quality.
Further, threaded line is a negative line.
Further, the pitch of threaded line is the 0.1-1 millimeter.
In order to overcome the quality problems that cause near biting of both sides autotype picture drop-out, the present invention can address this problem effectively, and effect is remarkable, the simple and practical and low processing cost of method.
The method that solves is: in the time of the face lathe machining on left magnetic roller two ends root surface; Again design the pitch and the direction of lathe threaded line; This hand of spiral is according to magnetic roller rotation and fixed; Purpose is that left magnetic roller normally duplicates direction when rotating, and utilizes the magnetic attraction developer and rotates when developing, and makes the wool fiber that comes off because of violent friction discharge to show along threaded line and prints out of my cabin; Therefore, of paramount importance is that the two ends of this magnetic roller must possess a pair of mutually opposite threaded line.Just, the surface of magnetic roller is not that a lathe cutter turning from one end to the other side forms, must be at twice, and turning is distinguished at two ends, causes the threaded line of mutual reverse rotation.
Effect of the present invention is: be the present invention's microcosmic ground research first and found that generation defective and key of problem belong in this area; Overcome long-term the turning a blind eye to and prejudice in market and this area; Adopted and the improvement technical scheme that is different from other people so far fully; Be that the present invention has proposed a kind of ingenious, targeted, cost-effective solution first, therefore, have very strong originality.
The problem that the present invention can prevent wool fibre to come off effectively the autotype both sides stopping up the ink powder feed path and cause bite; Also do not cause new problem through experiment, and this programme is simple in structure, is skillfully constructed; Do not increase part; Do not change fit, increase cost hardly and just solved this area and fail the crux of problem for a long time, not have technology, the quality difficult problem of solution for a long time.Even domestic duplicating machine uses to 40,000 quality problems that also can not cause a side, prolonged magnetic roller high-quality serviceable life greatly, the saving data improves the use value of copier part, and it is creative to have very strong patent.
Duplicating machine is the huge office accommodations of present domestic and international market owning amount, even seem small improvement, the growth in serviceable life; The saving of material, the energy is gathered together, and its economic worth and social benefit are very considerable; Therefore, creativeness of the present invention is very outstanding.
