Description
Technical field
The utility model relates to the mechanism using on a kind of rotary offset machine, the especially a kind of permanent tension force feeding-in roll of passive type mechanism of rotary offset machine.
Background technology
So-called rotary offset machine is generally comprised of paper feeding machine, printing unit, folding machine three each major parts.In the multicomputer colored printing of rotary offset machine, the no paper tape with stable tension that provides of paper feeding function, is the key factor that can multicomputer chromatography correct.And domestic existing paper supplying machine is used tension control system one time at present, can only provide a kind of macroeconomic stability to paper tape, the extremely unsettled paper tension of microcosmic.The unsettled web tension of this fluctuation, enter after printing unit, superimposed with the printing tension force that the inner printing of printing unit produces, thereby variation and the fluctuation of the inner printing of printing unit tension force have been strengthened, the variation of this tension force and fluctuation just have influence on the correctness of printing chromatography, that is to say the quality that can have influence on printing.
In order to address this problem, some producers have set up feeding-in roll between paper feeding machine and printing unit.Feeding-in roll is controlled by mechanical buncher, and is connected with the main transmission of printing unit, is moved, and produce tension force by feeding-in roll driving paper tape, Here it is active feeding-in roll.By this active feeding-in roll, can cut off unstable tension force of paper supplying machine fluctuation to printing the impact of the inner paper of unit road tension force, and provide adjustable constant-tension for printing unit.But the feeding-in roll of this mechanical transmission has two large shortcomings:
One, complex structure, inconvenient operation;
Two, the vibration of printing unit itself and the irregular operation that produces because of roller notch, can have influence on the tension variation of feeding-in roll paper feeding by main transmission, the feeding-in roll that affected by main transmission, and also hope can be improved.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide paper supplying machine a kind of both capable of blocking that the unstable tension force of paper tape is provided, microoscillations and the trace that can further stablize again the inner paper of printing unit road tension force change, further improve the printing condition of multicomputer printing, the permanent tension force feeding-in roll of the passive type mechanism of the rotary offset machine of the chromatography effect of raising multicomputer printing.
The technical scheme providing according to the utility model, the permanent tension force feeding-in roll of the passive type mechanism of described rotary offset machine, comprise wallboard and feeding-in roll, on wallboard, rotating turret is provided with paper feeding roll shaft, on paper feeding roll shaft, be fixed with feeding-in roll, be fixed with controller and bearing on wallboard, bearing is socketed on paper feeding roll shaft, on bearing, be fixed with brake, brake is connected by cable with controller; On described wallboard, be hinged with swinging mounting, on swinging mounting, be fixed with nip drum axle, on nip drum axle, be rotatablely equipped with pressure roller, on wallboard, be fixed with cylinder block, cylinder is installed on cylinder block, in the piston rod end of cylinder, is fixed with connector, connector is hinged on described nip drum axle.
Described brake is magnetic-powder-type brake.Described pressure roller is rubber type pressure roller.
The pulling force of feeding-in roll of the present utility model is controlled by brake, and brake is controlled by controller, and the pulling force of feeding-in roll and the tension force of paper tape just can be adjusted easily on controller.It is compared with traditional machine driving, buncher, the utlity model has simple in structure, easy to operate, reliable, be convenient to the advantages such as maintenance, and the vibration of printing unit itself can not have influence on the work of the utility model feeding-in roll mechanism conversely.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is the actual schematic diagram that uses of the present utility model.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.
The permanent tension force feeding-in roll of the passive type mechanism of this rotary offset machine, comprise wallboard 18 and feeding-in roll 20, on wallboard 18, rotating turret is provided with paper feeding roll shaft, on paper feeding roll shaft, be fixed with feeding-in roll 20, on wallboard 18, be fixed with controller 15 and bearing 17, bearing 17 is socketed on paper feeding roll shaft, is fixed with brake 16 on bearing 17, brake 16 is connected by cable with controller 15, and the model of described appliance controller 15 is KTC800A; On described wallboard 18, be hinged with swinging mounting 21, on swinging mounting 21, be fixed with nip drum axle, on nip drum axle, be rotatablely equipped with pressure roller 19, on wallboard 18, be fixed with cylinder block 23, cylinder 22 is installed on cylinder block 23, in the piston rod end of cylinder 22, be fixed with connector 24, connector 24 is hinged on described nip drum axle.
Described brake 16 is magnetic-powder-type brake.Described pressure roller 19 is rubber type pressure roller.
The paper tape 14 that printing roller drives, is coated on feeding-in roll 20 surfaces, and the swinging mounting 21 of being controlled by cylinder 22, pressure roller 19 is pressed on feeding-in roll 20, feeding-in roll 20 under the drive of paper tape 14, passive transfer.Brake 16 is under the control of controller 15, and energising produces braking moment, stops feeding-in roll 20 to rotate, thereby produces tension force, and the size of tension force is that controlled device 15 is controlled, till being adjustable to and printing out satisfied printing.
Paper feeding machine 2 is provided with paper roll 1 and tension mechanism 3, at the 4th printing unit 9 rears, is provided with folding unit 11, is provided with collecting roller mechanism 10, reticulate pattern feeding-in roll 12 and folding set square 13 on folding unit 11.During work, between paper feeding machine 2 and the first printing unit 5, paper tape has tension force F1, between the first printing unit 5, the second printing unit 7, the 3rd printing unit 8, the 4th printing unit 9, there is web tension F2, on the second printing unit 7, be provided with between printing roller 6, the four printing units 9 and folding machine 11 and have tension force F3.Tension force F1, F3 fluctuate, and tension variation is larger, and F2 is the tension force of the inner paper tape of printing unit, is metastable tension force.If there is no feeding-in roll mechanism 4 and collecting roller 10, forward pull F1, backward pull F3 can have influence on the first printing unit 5 to web tension F2 between the 4th printing unit 9, and the fluctuation variation of F2 just directly has influence on the error of chromatography.After setting up feed roll mechanism 4 and collecting roller mechanism 10, can block forward pull F1, backward pull F3 impact and the interference on the inner web tension F2 of printing unit.Thereby the larger printing condition that improves, improves the quality of printing chromatography.
Due to, feeding-in roll 20 passive transfer under the pulling of printing unit paper tape 14, and under the effect of electric current, brake 16 produces braking moment, braking moment stops the rotation of the feeding-in roll 20 of passive transfer, paper tape 14 produces pulling force, and this pulling force can be constant, and the tension force that is to say paper tape 14 is also constant.This constant tension force is overlapping with the inner web tension of printing unit, merges, and forms the more stable tension force of the inner web tension of a kind of ratio printing unit, and due to the improvement of printing condition, during multicomputer printing, chromatography meeting is more accurate.And the fluctuation tension force of the paper tape that paper supplying machine 2 provides is also blocked by feeding-in roll, can not have influence on again the variation of printing unit web tension.And the electric current of brake 16 can adjust arbitrarily by controller 15, that is to say tension force provided by the utility model be constant be also adjustable.
