Description
Technical field
The utility model relates to the improvement of offset press, particularly about the improvement of offset press paper feeder.
Background technology
Existing printing machine is the paper feeder of offset press for example; be on a platform, to stack smooth sufficient amount paper; rising to the certain altitude paper supply opens separator and carries one by one; in the process of defeated seal; after the paper of paper feeding platform uses up owing to pack into; shut down dress paper; Deng dress after paper finishes; can start shooting again and continue printing; owing to shut down the folding process printing is paused, produce the quality that the printing aberration influences printed matter, set about from reducing aberration; the printing that preferably do not stop is reduced to a minimum to guarantee aberration.
Summary of the invention
The technical problems to be solved in the utility model is a kind of alternately continuous paper feeder of lifting of design, reaches printing machine and do not shut down printing in printing process, reduces the printing aberration.
The utility model adopts following design to address the above problem.
Non-stopping paper feeding device for offset press; it comprises paper pushing motor; driving-chain; drive and the stacker platform that is suspended on the driving-chain end; and touch switch circuit; it is characterized in that establishing major-minor driving-chain and major-minor drive; and be suspended on the major-minor stacker platform of driving-chain end; described main stacker platform is made up of main stacker framework and the main stacker plate that rests on the main stacker framework; described secondary stacker platform is made up of secondary stacker frame and the paper transfer rod that rests on the secondary stacker frame; the main stacker framework of lifting is located in the secondary stacker frame of lifting alone alone, and the paper transfer rod is alternately displacement between main stacker framework and secondary stacker frame.
The main stacker plate that rests on the main stacker framework is fixed basically, and the paper transfer rod that rests on the secondary stacker frame is transportable, when needing, can insert in the main stacker plate on the main stacker framework, transfer to alternately lifting on the secondary stacker frame being stacked on the main stacker plate paper, thereby realize uninterrupted paper feeding.When the paper on the main stacker framework is delivered to when a certain amount of, the paper transfer rod is inserted in the main stacker plate, stacker is transferred on the secondary stacker frame, replace the work of main stacker platform.The descend paper of packing into of main stacker platform rises to certain position again; can take out the paper transfer rod that rests on the secondary stacker frame; secondary stacker frame just can drop to the height that needs; wait the arrival of the stacker on the main stacker framework; so constantly circulation; thereby realize that primary and secondary stacker platform replaces lifting, the assurance offset press is not shut down printing.
The utility model and existing single platform stacker platform stack the paper feeding of paper discontinuity and open and compare, do not influence the continuity printing of offset press, the aberration that is produced can obviously improve, owing to adopt major-minor stacker platform to replace the dynamic structure that lifting paper feeding and paper transfer rod shift on major-minor stacker platform, having solved the technical barrier of continuously uninterrupted paper feeding, is outstanding advantage of the utility model and marked improvement for present offset press.
