Abstract
The utility model discloses a static -removing device for sheet -fed offset press fails paper unit, including pressing the paper blow gun, press the air inlet of paper blow gun to have the air pump through the pipe connection, still be connected with the humidifier on the pipeline between pressure paper blow gun and the air pump, press the top of paper blow gun to be provided with the connecting rod, the connecting rod is connected with printing machine paper feed mechanism drive part's cam. The utility model discloses can effectual elimination paper quiet electric phenomena within a definite time to can work voluntarily, do not need manual operation, saved manpower resources the quick improvement time of destaticing, improve work efficiency greatly, simultaneously, can adjust humid air's inlet according to the thickness of paper to the messenger removes static electricity effect and reaches the best, through setting up filter equipment, can avoid the impurity in the air pump blowout gas to block up pressure paper blow gun, and then improve the life of this device, reduce the maintenance cost.
Description
Technical field
The utility model belongs to printing technology, is specifically related to a kind of Destaticizing device for the defeated paper unit of sheet-fed offset press.
Background technology
The conveyer of offset press is the important component part of offset press, and paper only has the printing that just can be reached offset press by conveyer, completes presswork smoothly.Current paper feed mechanism for offset machine is mainly based on pneumatic continous way automatic paper feed.Be separated in paper process in defeated paper part, 5 ~ 10 paper on paper stack top layer to be printed first blow pine by loose paper blow gun, then are picked up by paper stack surface a piece of paper by shaking of paper separation suction nozzle, and platen blow gun falls, push down paper stack except the paper stack below surperficial a piece of paper, and dry, between paper stack a piece of paper and second paper, form air layer, be beneficial to the separation of paper, then, paper feeding suction nozzle inhales paper, and shaking of paper separation suction nozzle puts paper simultaneously, and paper delivers to defeated cardboard by paper feeding suction nozzle.Because preceding sheet and rear a piece of paper have certain relative motion in defeated paper process, so easily produce electrostatic between paper and paper, the generation of electrostatic can have a strong impact on the stationarity of paper transmission, cause the faults such as oblique and double sheet.The existing method that destatics is generally install static bruss on the printer or manually sprinkle water earthward, to alleviate defeated paper electrostatic breakdown, but effect is general, particularly eliminate electrostatic in the mode of manually sprinkling water, ground moisture evaporation is made to reach paper surface, need long time, cause static elimination efficiency low.
Utility model content
The purpose of this utility model is to provide a kind of Destaticizing device for the defeated paper unit of sheet-fed offset press, which solves the problem that the defeated paper unit of existing sheet-fed offset press thoroughly cannot eliminate electrostatic.
The technical scheme that the utility model adopts is, a kind of Destaticizing device for the defeated paper unit of sheet-fed offset press, comprise platen blow gun, the air inlet of platen blow gun is connected with air pump by pipeline, and the pipeline between platen blow gun and air pump is also connected with humidifier; The top of platen blow gun is provided with connecting rod, and connecting rod is connected with the cam of printing machine paper feed mechanism running part.
Feature of the present utility model is also,
For being rigidly connected between platen blow gun and connecting rod.
Control valve is provided with between humidifier and platen blow gun.
The port of export of air pump is provided with filter.
Filter is filter screen.
The beneficial effects of the utility model are, by arranging the platen blow gun that can spray humid air on the defeated paper unit of sheet-fed offset press, effectively can eliminate the electrostatic phenomenon between paper, and energy automatic operation, do not need manual operation, while raising destatics the time fast, save human resources, greatly increase work efficiency; By arranging control valve, the inlet of humid air can be regulated according to the thickness of paper, thus make to destatic effect and reach best; By arranging filter, the impurity that air pump can be avoided to spray in gas blocks platen blow gun, and then improves the service life of this device, reduces maintenance cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model Destaticizing device.
In figure, 1. humidifier, 2. control valve, 3. air pump, 4. connecting rod, 5. platen blow gun, 6. filter.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
As shown in Figure 1, a kind of Destaticizing device for the defeated paper unit of sheet-fed offset press of the utility model, comprise platen blow gun 5, the air inlet of platen blow gun 5 is connected with air pump 3 by pipeline, pipeline between platen blow gun 5 and air pump 3 adopts flexible pipe, and the pipeline between platen blow gun 5 and air pump 3 is also connected with humidifier 1; The top rigid of platen blow gun 5 is connected with connecting rod 4, and connecting rod 4 is connected with the cam of printing machine paper feed mechanism running part, swings up and down to control platen blow gun 5; Be provided with control valve 2 between humidifier 1 and platen blow gun 5, the port of export of air pump 3 is provided with filter screen.
Using method of the present utility model is, platen blow gun 5 is downward platen under the effect of connecting rod 4, push down paper stack surface except the paper stack below a piece of paper, air pump 3 air feed simultaneously, while air pump 3 air feed, the gas containing certain moisture is pressed into air supply channel between air pump 3 and platen blow gun 5 by valve 2 by humidifier 1.Air with certain moisture blows out from platen blow gun 5, between paper stack surface a piece of paper and second paper, forms thin layer of air, is used for being separated paper.The water content of the gas that platen blow gun 5 is produced by boasting can be regulated by valve 2, to ensure that the water content of paper meets normal print request, the electrostatic produced due to friction between paper and paper be can significantly reduce again simultaneously, thus oblique and fault of re-opening producing in defeated paper process reduced.
