Description
Technical field
The present invention relates to a kind of parts of offset press, relate in particular to a kind of roller control device of offset press.
Background technology
Printing enterprise, in using the production of offset press printing printing, need to require to change forme according to printing, and when starting to print, " white edge " phenomenon appears in several Zhang Yinpin that usually can encounter above, thereby these printed sheets are all waste products.When this phenomenon occurs in the printing of long version, impact may be little, but in the increasing situation of printing of short run now, the waste that " white edge " causes is just very important.The reason that produces " white edge " is: encapsulate roller is to carry out one step completed (seeing Fig. 1) by a cylinder 3 with the combined pressure of forme roller, impression roller respectively, this mechanism also comprises connector 1, the first rocking bar 2 and the second rocking bar 4, one side of the first rocking bar 2 is connected with the lower end of connector 1, one side of the second rocking bar 4 is connected on a fixed axis 6, another side of the second rocking bar 4 be connected to one vertically to axis body 7 on, the intermediate ends of the second rocking bar 4 is connected with cylinder 3.According to encapsulate roller 10 respectively with the arrangement mode (seeing Fig. 2) of forme roller 20, impression roller 30, when the imperfect portion 100,200 of encapsulate, forme roller has alignd, encapsulate, no alignment of the imperfect portion of impression roller 100,300, vice versa.Addressing this problem must be in the imperfect portion alignment punishment time combined pressure of imperfect portion alignment place of encapsulate, forme roller and encapsulate, impression roller.Because twice response time of the magnetic valve of control cylinder cannot coordinate with the time of covering two imperfect portions, if therefore complete gradation combined pressure by a cylinder, be difficult to realize.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of and can reduce waste product incidence, the roller control device of the offset press improving the quality of products.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of roller control device of offset press, comprise the connector connecting successively from top to bottom, the first rocking bar, cylinder and the second rocking bar, the pedestal of the encapsulate roller of the upper end of described connector and described offset press, the centre of described the first rocking bar is provided with a fixing rotating fulcrum, one side of described the first rocking bar is connected with the lower end of described connector, one side of described the second rocking bar is connected on a fixed axis, another side of described the second rocking bar be connected to one vertically to axis body on, it is characterized in that: described cylinder is comprised of the first cylinder and the second cylinder, both are with one upwards, another downward back-to-back series system connects, the piston rod of described the first cylinder is connected with another side of described the first rocking bar, the piston rod of described the second cylinder is connected with the intermediate ends of described the second rocking bar.
Described the first cylinder and the second cylinder are two-way cylinder also respectively by a solenoid control.
The piston rod of described the first cylinder is connected with another side of described the first rocking bar by a bearing.
Compared with prior art, the beneficial effect that the present invention has is:
The present invention adopts the cylinder series connection of two different strokes to place, and controlled respectively by two magnetic valves, imperfect portion alignment punishment in imperfect portion alignment place of encapsulate, forme roller and encapsulate, impression roller realizes encapsulate, forme roller combined pressure and encapsulate, impression roller combined pressure for twice, thereby eliminated " white edge " phenomenon, reduce waste product incidence, improved product quality.

Fig. 3 is the structural representation of the roller control device of a kind of offset press of the present invention.
In figure, be labeled as: connector 1, the first rocking bar 2, cylinder 3, the first cylinder 31, bearing 310, the second cylinder 32, the second rocking bar 4, pedestal 5, the interior ring ring heart 51, the outer shroud ring heart 52, fixed axis 6, axis body 7, the first fixed body 81, the second fixed body 82, encapsulate roller 10, forme roller 20, impression roller 30, the imperfect portion 100 of encapsulate roller, the imperfect portion 200 of forme roller, the impression imperfect portion 300 of roller.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
As shown in Figure 3, a kind of roller control device of offset press, comprises the connector 1, the first rocking bar 2, cylinder 3 and the second rocking bar 4 that connect successively from top to bottom.Wherein:
The upper end of connector 1 is connected on pedestal 5, the interior ring ring heart of this pedestal 5 51 and the outer shroud ring heart 52 decentraction, and its inner circle is enclosed within the axis coinciding that makes the ring ring heart 51 and encapsulate roller 10 it in the rotating shaft of encapsulate roller 10 of offset press;
The centre of the first rocking bar 2 is provided with a swing fulcrum, and its side is connected with the lower end of connector 1, and another side connects cylinder 3;
One side of the second rocking bar 4 is connected on a fixed axis 6, another side of the second rocking bar 4 be connected to one vertically to axis body 7 on, the high and low position of this side is adjustable, regulates the position of this side can make sleeve mechanism adapt to the requirement of different-thickness paper to different printing pressure;
Operation principle of the present invention is: stretching out or retracting of the first cylinder 31 or the second cylinder 32 piston rods all can drive the first rocking bar 2 to rotate, by the first rocking bar 2, pull or promote connector 1, connector 1 pulls or promotes pedestal 5 again, can rotate around the outer shroud ring heart 52 of pedestal 5; Pedestal 5 is fixing by the first fixed body 81, the second fixed body 82, and when connector 1 pulls or during impeller-hub bearing 5, the outer shroud ring heart 52 is motionless, but the position of the interior ring ring heart 51 of pedestal 5 is changing.Due to the interior ring ring heart 51 of pedestal 5 and the axis coinciding of encapsulate roller 10, so the axle of encapsulate roller 10 also changes with the change in location of the interior ring ring of pedestal 5 heart 51, thereby changed the distance (seeing Fig. 2) between encapsulate roller 10 and forme roller 20 and impression roller 30, realized clutch pressure.Cylinders retract is combined pressure state.Be chosen in encapsulate roller and, control the piston rod of the first cylinder 31 and retract when relative with the imperfect portion of version roller, complete the combined pressure of encapsulate roller 10 and forme roller 20.In roller, turn over after certain angle, when encapsulate roller is alignd with the impression imperfect portion of roller, control the piston rod of the second cylinder 32 and retract, complete encapsulate roller 10 and the combined pressure that impresses roller 30.
Those of ordinary skill in the art will be appreciated that, above embodiment is only for the present invention is described, and be not used as limitation of the invention, as long as within the scope of connotation of the present invention, to the variation of the above embodiment, modification, all will drop within the scope of claim of the present invention.
