Abstract
The utility model relates to a paper positioning mechanism of a paper transfer table of a sheet lithographic offset press, comprising a front gauge and side gauges, wherein, the side gauges are arranged on the two side walls of the front end of the paper transfer table and the front gauge is connected to a support of an impression cylinder through a front gauge shaft. The utility model is characterized in that a lateral air groove is arranged below the front end of the paper transfer table, a lateral air groove is connected with a plurality of small air holes at the upper surface of the front end of the paper transfer table, and the lower part of the lateral air groove is provided with an air nozzle connected with an air pump. The utility model has the advantages of simple structure, low cost, convenient use, easy adjustment, overprint accuracy guarantee and ideal effects, and the accuracy can reach more than 98%.
Description
The utility model relates to a kind of parts of individual offset print, paper passing platform paper detent mechanism in particularly a kind of individual offset print.
In existing individual offset print, its paper passing platform paper detent mechanism is made up of preceding rule and side mark, preceding rule are bearing on the frame, side mark is fixed on the paper passing platform, rule place before paper is delivered to paper by paper feed mechanism on paper passing platform, moving of the spacer restriction paper of preceding rule finished the location, front of paper.Side mark has a paper to pull to the action of side mark spacer then, the paper of reserving the position, front is pulled to the side mark spacer carry out the location, side.The paper tooth of stinging of the paper right here waiting impression cylinder of reserving is stung paper, and after impression cylinder was stung paper, preceding rule were lifted immediately, and paper is followed the impression cylinder motion and printed under the drive of stinging the paper tooth.The actuation time that the above-mentioned whole location and the process of gritting one's teeth allow on existing printing machine is very short, (3600 change/hour) only there is 1/360 second, then Yi Shang sequence of movement is difficult to adjust, rule can not be lifted in time before tending to cause when stinging the paper tooth favores with paper feed, paper is pulled open, when perhaps stinging the paper tooth and also not stinging paper before rule lift in advance, paper can not be located well, make chromatography precision lower, can only reach about 80%.
The purpose of this utility model is exactly in order to address the above problem, and provides a kind of adjustments easy, and accurate positioning can guarantee to advise and negative pressure integrated positioning mechanism before the offset press machinery of chromatography precision.
Technical solution of the present utility model:
Rule and negative pressure integrated positioning mechanism before a kind of offset press machinery, the preceding rule 2 of regulation bit slice 1 and the side mark 3 that has the side mark spacer before it includes and has, wherein side mark 3 is arranged on the paper passing platform 4 front end two sides, preceding rule 2 are connected on the support of impression cylinder by preceding rule axle 5, and it is positioned at the front end of paper passing platform 4, it is characterized in that below the front end of paper passing platform 4, being provided with horizontal air drain 6, this horizontal air drain 6 is connected with a plurality of spileholes 7 to paper passing platform 4 front end upper surfaces, and laterally air drain 6 bottoms are provided with a valve that links to each other with air pump 8.
The utility model organically is combined as a whole vacuum air pump and preceding rule side mark first, forms the negative pressure detent mechanism, and it is simple in structure, and cost is low, and is easy to use, adjusts easily, can guarantee the chromatography precision of paper, and precision can reach more than 98%, and effect is very good.Detent mechanism wide application of the present utility model all is suitable for various paper.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
As Fig. 1,2, during the utility model work, when paper 9 transfers to paper passing platform 4 front ends by transport sector with paper 9 on paper passing platform 4, blocked by preceding regulation bit slice 1, carry out the location, front of paper 9, Yi Bian side mark 3 has one paper 9 pulled to one's own side's action then, and paper 9 is abutted on its side mark spacer, carries out the side location of paper 9.Connect air pump this moment, bleed in horizontal air drain 6 by valve 8, make to form negative pressure in the air drain 6, so just paper 9 is adsorbed on the front portion of paper passing platform 4 by a plurality of spileholes 7, paper 9 is positioned on the position of being determined by preceding regulation bit slice 1 and side mark spacer 3, and keeps motionless.Rule 2 are lifted then, the paper tooth 11 of stinging on the turnover panel 10 of paper 9 wait impression cylinders is stung paper, in case after stinging on the paper tooth axle 12 one group and stinging paper tooth 11 and sting paper 9, air pump is just in inflation in horizontal air drain 6 under the control system effect, remove negative pressure, paper 9 can float with stinging paper tooth 11 and enters impression cylinder printing, finishes location, the printing work process of a piece of paper.The repetitive cycling said process can guarantee preceding rule 2 and sting 11 coordinations of paper tooth later on, guarantees chromatography precision.
