Detailed description of the invention
Referring to figs. 1 through Fig. 2, the utility model printing machine embodiment is described further.
As described in Figure 1, a kind of printing machine, it has pay-off 1, printing equipment 2 and folding apparatus 3.After roll web rolls out by pay-off 1, be fed through printing equipment 2 and carry out presswork, after presswork terminates, be fed through folding apparatus 3, carry out folding after send to outside.
The printing equipment 2 of the present embodiment has Liang Ge printing mechanism, and Liang Ge printing mechanism breaches traditional kind of drive, and adopts power transmission shaft 22 to carry out Synchronous Transmission.
Particularly, owing to needing the mainly roller class A of geometric unitA driven in printing mechanism, and the driving of roller class A of geometric unitA normally adopts gear-box 21, is provided with multiple gear controlling differential roller respectively in gear-box 21.All roller class A of geometric unitA are all realize unified driving by engaging each other of gear.And when needs roller class A of geometric unitA rotating speed is different, the requirement of gear different rotating speeds just can be realized by the modulus changing gear.And the driving of gear-box 21 is gears by linking with motor shaft realizes.
By above-mentioned, the present embodiment adds power transmission shaft 22 between original motor and gear, is used as synchronously driven medium.Namely, first drive power transmission shaft 22 by motor shaft, then carry out the gear in driving gearbox 21 by power transmission shaft 22, achieve the normal work of gear-box 21.
Consider further, all devices due to printing machine is in same work straight line, and Ze Liangge printing mechanism is arranged in a linear along the direction of displacement of roll web.So, power transmission shaft 22 successively through Liang Ge printing mechanism, can realize to carry out transmission point-blank.
As described in Figure 2, the present embodiment is provided with bearing 23 in the side, front and back of gear-box 21, is used for accepting the power transmission shaft 22 through gear-box 21, and the part being positioned at gear-box 21 at power transmission shaft 22 is provided with transmission conical tooth 25.Suitablely, the present embodiment is transformed into as the driving cog of driving input the conical tooth 24 engaged with transmission conical tooth 25 using in gear-box 21.
By above-mentioned structural design, the Liang Ge printing mechanism of the present embodiment achieves synchronous operation by power transmission shaft 22, efficiently solves printing mechanism in prior art and runs asynchronous, cause printing the problem occurring deviation.
Power transmission shaft 22 between Liang Ge printing mechanism cuts off by the present embodiment further, forms two and independently holds axle, is fixed between two end axles by shaft coupling again.The object of such design is, makes printing mechanism's independent of the present embodiment, blocking.When without the need to Liang Ge printing mechanism, by opening shaft coupling, realizing the separation of two end axles, being suitable for industrial production.
It is worth mentioning that, the circumference that the power transmission shaft 22 of the present embodiment can realize motor shaft and power transmission shaft 22 by synchronous cog belt and electric machine shaft driving links.
In addition, top margin of a page gear-box 33 has power shaft 331, power shaft 331 and power transmission shaft 22 coaxial linkage, power shaft 331 and output shaft 332 pass through meshed transmission gear, the upper synchronous pulley 311 of the input roller coaxial linkage of top margin of a page transmission case, Timing Belt 312 and the lower synchronous pulley 313 with power transmission shaft 22 coaxial linkage, upper synchronous pulley 311 and lower synchronous pulley 313 are by Timing Belt 313 transmission.
Top margin of a page gear-box 33 has jackshaft 333, and after power shaft 331 is linked by gear and jackshaft 333, jackshaft 333 is linked by gear and output shaft 332, output gear 3331 and jackshaft 333 coaxial linkage.
So, the folding apparatus 3 of the present embodiment can keep synchronous operation with printing equipment 2, and when placement folding apparatus 3 is asynchronous with printing equipment 2, paper purses up and enters air, makes folding apparatus 3 fold out-of-flatness.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
