The nearly four kinds of modes of traditional printer deviation correction mechanism: all correction wheels of the first are contained on the same correction wheel shaft, spring is pressed in the both sides of correction wheel shaft, this linearity to axle requires very high, simultaneously when narrower paper passes through a side of correction passage, owing to have only side correction wheel stressed, will inevitably cause the crooked of correction wheel shaft, thereby make the correction power of paper both sides inconsistent, bring unfavorable rectifying effect.If guarantee not crookedly, just must increase mechanism and guarantee to rectify a deviation and lift synchronously about wheel shaft or depress, this will certainly cause mechanism's complexity, cost increase.It two is per two correction wheels to be contained in constitute correction wheel assembly, total some groups on the axle.Each group all has a spring to be pressed in the centre of correction wheel shaft.Though mode has been avoided first kind of mode to the higher linearity of axle, and the requirement of left and right sides lazy-tongs in this.But because spring is the centre that is pressed in axle, like this when paper during simultaneously by two correction wheels in the correction wheel assembly, the pressure that correction is taken turns paper is 1/2 of spring pressure.When paper is that this correction wheel will be 1/4 of spring pressure to the pressure of paper by a correction wheel in one group of correction wheel assembly.This paper that will cause same thickness is when the diverse location of correction passage passes through, and it is bigger that correction power can differ.It three is that all correction wheel all is independently, and each correction wheel all has the independent rotation axle, and independently spring though this is beneficial to rectifying effect, also can cause mechanism's complexity, cost increase.It four is to adopt elasticity to brush paper, though this mode is simple in structure, price is also cheap, and the correction time is longer, influences office efficiency, and rectifying effect is undesirable, especially to ground paper.
Elasticity wheel body in the traditional printer correction wheel has and adopts rubber, have to adopt the axial elasticity reed, has to adopt correction wheel deadweight.The employing rubber elastomer, because rubber parts hardness uniformity is bad, precision be cannot say for sure to demonstrate,prove, and is difficult to guarantee the uniformity of correction power; Employing axial elasticity reed, existing radial deformation when reed is out of shape also has axial deformation, and this is unfavorable to the stationarity that guarantees the correction wheel rim; Adopt the correction wheel to conduct oneself with dignity, because correction wheel self gravitation is constant, can be along with paper thickness change and change, very difficult ground paper and the thin paper of being suitable for simultaneously.
In the such scheme, the performance that has is good inadequately, the complex structure that has, and part is more, and cost is higher.
Summary of the invention:
The purpose of this utility model provides a kind of paper deviation correction mechanism that is applicable to impact printer, by simple frame mode, overcomes the some shortcomings part of conventional printer, more perfectly realizes the needed function in market.Paper adaptability to different-thickness is strong, any position of paper in the correction passage, correction power unanimity.Simple in structure, with low cost, installation, easy to maintenance.
The utility model is achieved in that the paper deviation correction mechanism that is applicable to impact printer, by some correction wheel assemblies, reed and pressure regulating shaft constitute, every correction wheel assembly comprises two correction wheels and the support between two correction wheels, each correction wheel comprises a radial elastic claw and a correction wheel rim, the correction wheel rim is wrapped in the outer ring of radial elastic claw, radial elastic claw and support casing are contained on the correction wheel shaft, the reed fixing with the pressure regulating shaft is pressed on the support, and correction wheel assembly and drive roll are installed side by side.Therefore, be pressed on the paper by elasticity of spring leaf correction wheel assembly, will produce different pressure to different paper sheet thickness, promptly the paper to different-thickness produces corresponding paper feed frictional force, thereby realizes the deviation-correcting function of paper.
The end of elastic spring is provided with two supporting legs, support is provided with two contact jaws corresponding with two supporting legs, elastic spring is pressed in the support two ends of correction on the wheel assembly, and when making two correction wheels in the correction wheel assembly contact with paper simultaneously or separately, correction power variation of each correction wheel not quite.
The beneficial effects of the utility model are: different to the pressure of the paper of different-thickness by reed with elastic pawl, obtain different pressure and frictional force.It is simple in structure, and is with low cost.According to the utility model structure, can obtain reliable paper automatic deviation correction mechanism, install, easy to maintenance.
Description of drawings:
Below in conjunction with accompanying drawing and specific embodiments the utility model is described in further detail.
Fig. 1 is the lateral plan of correction wheel
Lateral plan when Fig. 2 works for the correction wheel assembly
Front view when Fig. 3 works for the correction wheel assembly
Fig. 4 is the 3D topology view of deviation correction mechanism
Referring to Fig. 1,2,3,4, this deviation correction mechanism mainly is made up of following parts: 1 correction wheel rim, 2 elastic claws, 3 supports, 4 correction wheel shafts, 5 reeds, 6 pressure regulating shafts, drive roll on 7,8 shaft couplings, 9 times drive rolls, 10 paper, 11 gates.
The specific embodiment:
Fig. 1 is the lateral plan of correction wheel.The correction wheel is made up of correction wheel rim and elastic claw, and the correction wheel rim can produce by elastic claw and move radially.The correction wheel rim is contained on the outer ring of elastic claw of radial elastic pawl, and the paper of different-thickness makes elastic support generation radial deformation during by the correction wheel rim, thereby obtains different pressure.
Lateral plan when Fig. 2 works for the correction wheel assembly.Correction wheel drive paper moves forward during correction, and gate is used for top of form is ajusted.Paper thickness difference, the pressure of reed are also different, and correction power will increase along with the increase of paper sheet thickness.
Front view when Fig. 3 works for the correction wheel assembly.Correction wheel and last drive roll all are contained on the correction wheel shaft, constitute the correction wheel assembly.The elastic force of reed makes the correction wheel assembly be pressed on the paper, the correction wheel is bigger than last drive roll, when paper sheet thickness is relatively thinner, because the elastic force of the elastic claw on the correction wheel, make and have only the correction wheel to contact, be lifted, do not run into paper and go up drive roll with paper, correction frictional force is less relatively like this, helps the correction of thin paper.When paper was thicker, because the reed distortion is bigger, elastic force was also bigger, and the elastic force of elastic claw is not enough to lift drive roll, and therefore the correction wheel all contacts with paper with drive roll, and the frictional force of at this moment rectifying a deviation is bigger, and this helps the correction of ground paper.Each correction wheel assembly all has reed to be pressed in the support two ends of correction on the wheel shaft, this makes when the correction wheel at correction wheel assembly two ends contact with paper simultaneously or separately, and the correction power unanimity that each correction is taken turns has avoided a spring to be pressed in defective when middle.
Fig. 4 is the 3D topology view of deviation correction mechanism, and several correction wheel assemblies connect by shaft coupling, can be suitable for different printer width.Certainly generally speaking, every printer comprises a pair of correction wheel assembly at least.
Elasticity wheel body in the correction wheel adopts the radial elastic claw, every radial elastic claw has five to 12, the correction wheel rim is installed in outer ring on the elastic claw (Fig. 1), the correction wheel rim produces by elastic claw and moves radially like this, because elastic claw has only radial deformation, therefore the correction wheel can be not crooked, and operating ratio is more steady.
Reed is pressed in the two ends (Fig. 3) of support, this makes when the correction wheel at correction wheel assembly two ends contacts with paper simultaneously or separately, the correction power unanimity of each correction wheel, all very near 1/2 of reed group pressure, so any position of paper in the correction passage can obtain identical rectifying effect.
As mentioned above, the utility model has adopted simple structure, has realized the function that needs, and has leading advantage at the paper of carrying different-thickness, adapts to the needs of domestic various print states more.
