The utility model further has the characteristics of reasonable structure and convenient replacement.

Description

Offset press do not shut down a version position governor motion

Technical field

The utility model relates to a kind of offset press, especially a kind of version position governor motion of offset press.This mechanism allows offset press to do the position adjustment of non-stop-machine version in operation process.

Background technology

The version position governor motion of existing offset press can be consulted Fig. 1, it includes wallboard 4, at interior axle 2 in outer shaft 3 of the outer shaft of installing on the wallboard 2, kink, be installed in axle one end governor motion 1, be installed in axle end and the crank mechanism 7 that is connected with paper-pushing toothed-edge 8 in addition, and one be connected to drive the driven wheel 5 of interior rotation with gear drive 12.When the offset press operate as normal, the gear drive 12 drive space of a whole page rollers 11 of offset press, rubber roller 10, impression roller 9 are done synchronous rotation; Meanwhile, axle 2, crank mechanism 7 made paper-pushing toothed-edge 8 push away the paper motion in this gear drive drove by driven wheel 5 again.As adjusting the version position, then to remove to rotate interior axle by governor motion 1, and by 7 motions of interior axle drive crank mechanism, to change the original position of paper-pushing toothed-edge 8.Its shortcoming is: when adjusting the version position, must be by interior axle, and interior axle at this moment is with gear drive simultaneously and is rigidly connected and is turning round, two kinds of motions can't be carried out on an axle simultaneously; Therefore to carry out the adjusting of version position, just must shut down earlier, and can only after adjusting finishes, could start shooting again.People regulate the shutdown of the version position governor motion of existing offset press and feel inconvenience, and after adjusting to the right place when shutting down through being everlasting, and a start still error may occur and not in place, regulates repeatedly so need repeat to shut down, and are both time-consuming, require great effort, and also influence the efficient of offset printing.

Summary of the invention

The utility model is to overcome the shortcoming that exists in the above-mentioned prior art, and what a kind of offset press was provided does not shut down a version position governor motion, so that it has is easy to adjust, the carrying out that do not influence offset printing process, and characteristics such as simple and reasonable.

The utility model offset press do not shut down a version position governor motion; it contains interior axle; the governor motion of axle one end in being installed in; the driven wheel that is connected with the gear drive of roller; it is characterized in that: it also has output shaft adjacent with interior axle and coaxial line; this is from an end adjacent with interior axle; transition gear is housed successively; sun gear with the driven wheel engagement; be fixed on the interior shaft gear on the output shaft; wherein the wheel hub of transition gear is connected and its teeth and one group of pinion with interior axle by pin; and the wheel axial symmetry of pinion is installed on the wheel body of sun gear; and this wheel shaft is overhanging on sun gear, and the end tooth wheel with interior shaft gear engagement is housed on this overhanging end.

The beneficial effects of the utility model: 1) not shutting down of this practical offset press regulated version position mechanism, can be implemented in the adjustment of finishing the version position in the offset press running, this adjusts not only convenient, but also the state when adjusting is exactly the duty of offset press, thus positioning accurate and save time, laborsaving; 2) it simple and reasonable, use reliably, and it can replace existing adjustings a version mechanism easily, and need not change the overall structure of offset press, so help the update to offset press.

The specific embodiment

Embodiment: the utility model offset press do not shut down a version position governor motion, its structure can be seen from Fig. 2 and Fig. 3, axle 1 in it contains, be installed in the governor motion 1, the driven wheel 5 (representing driven wheel with double dot dash line among Fig. 3) that is connected with the gear drive 12 of space of a whole page roller 11, rubber roller 10, impression roller 9 of axle one end, a wherein interior kink is at one fixedly in the outer shaft 3 on the wallboard 4; It also has the output shaft 7e of an and coaxial line adjacent with interior axle 2, from this output shaft and the adjacent end of interior axle, transition gear 7a is housed successively, with the sun gear 7c of driven wheel 5 engagement, be fixed on the interior shaft gear 7f on the output shaft, and the wheel hub of transition gear 7a is connected with interior axle 2 by pin 2a, and its teeth and two pinion 7b engagements; The wheel axial symmetry of these two pinion 7b is installed on the wheel body of sun gear 7c, and this wheel shaft is overhanging on sun gear 7c, and the end tooth wheel 7d with interior shaft gear 7f engagement is housed on its overhanging end.

When the offset press operate as normal, power on the gear drive 12 and move through driven wheel 5 and pass to sun gear 7c, sun gear has driven the wheel shaft of pinion 7b, drive the interior shaft gear 7f that is meshed with its teeth by the wheel of the end tooth on wheel shaft 7d again, output shaft 7e is rotated and make paper-pushing toothed-edge 8 push away paper and move by crank mechanism 7.

As in offset printing process, adjusting the version position, axle 2 rotates in outer shaft 3 in then will making by governor motion 1, at this moment axle directly drives transition gear 7a and takes turns 7d and interior shaft gear 7f through transition gear driven pinion 7b, end tooth in, this motion is added on the output shaft 7e, thereby changed the phase angle of the crank mechanism 7 that is connected with output shaft 7e, even do corresponding the adjustment through 8 editions positions of paper-pushing toothed-edge.
