[0029] like Figure 1 , Figure 2 and Figure 8 As shown, as a preferred embodiment of the present invention, the limiting guide mechanism 800 includes a fixed column 810, a ring 820, an adjustment column A830, an adjustment column B840, a limiting column 850, an adjusting screw 860 and a limiting guide wheel 870.

The multiple circulation components 600 drive the pressure control mechanism 900 thereon to rotate synchronously and cyclically. The pressure control mechanism 900 can effectively convey the packaging plate in contact with it below by circulating rotation, so that it can enter the feed end of the printing press stably and efficiently, meet the device's needs for conveying diversified packaging plates, significantly improve the conveying efficiency and conveying quality of the device, and thus improve the printing efficiency of the printing press.

[0034] like Figures 2 to 7 As shown, as a preferred embodiment of the present invention, the circulation component 600 includes a synchronous wheel A610, a synchronous wheel B620, a synchronous belt 630 and a sleeve 660.

[0038] In this embodiment, the pneumatic conveying equipment can not only pressurize external gas into the pressure control part 940 through the hose 910 and the connecting pipe 920, so that the pressure control part 940 expands on the synchronous belt 630, but also suck the gas in the pressure control part 940 to the outside, so that it contracts on the synchronous belt 630, thereby changing the distance between the outside of the pressure control part 940 and the device seat 100, so that the outside of the pressure control part 940 can effectively contact the surface of the packaging board of different thicknesses, thereby ensuring that the pressure control part 940 can efficiently and stably convey the packaging board it contacts to the printing press during the circulation process, thereby meeting the device's conveying requirements for diversified packaging boards, significantly improving the conveying efficiency and conveying quality of the device, and thereby improving the printing efficiency of the printing press.

[0039] In a preferred embodiment, the pressure control unit 940 can not only meet the needs of packaging board transportation through gas delivery or gas exhaust, but also reduce damage to the surface of the packaging board, ensure the overall aesthetics of the packaging board, and reduce the production scrap rate of the packaging board.

The synchronous wheel B620 can drive the synchronous belt 630 to circulate on the mobile rack 500 by cooperating with the synchronous wheel A610. The synchronous belt 630 drives the pressure control mechanism 900 thereon to circulate. The pressure control mechanism 900 can effectively transport the packaging plate in contact with it through circulatory rotation, so that it can stably and efficiently enter the feed end of the printing press. The pneumatic conveying device can not only pressurize the external gas into the pressure control part 940 through the hose 910 and the connecting pipe 920, so that the pressure control part 940 expands on the synchronous belt 630, but also suck the gas in the pressure control part 940 to the outside, so that it contracts on the synchronous belt 630, thereby changing the distance between the outer side of the pressure control part 940 and the device seat 100, so that the outer side of the pressure control part 940 can effectively contact the surface of the packaging board of different thicknesses, thereby ensuring that the pressure control part 940 can efficiently and stably convey the packaging board it contacts to the printing machine during the cyclic rotation process; When it is necessary to effectively limit and convey packaging boards of different specifications, the motor A411 drives the transmission belt A412 to rotate, and the transmission belt A412 drives a horizontal guide column 300 with threaded teeth 310 at one end to be connected, and the horizontal guide column 300 with threaded teeth 310 at one end drives a mobile frame 500 located at the end to slide through a screw sleeve 520, and the mobile frame 500 located at the end drives the connecting rod A422 thereon to rotate, and the connecting rod A422 located at the end drives the connecting rod A422 connected to it to rotate in the opposite direction. Similarly, the connecting rods A422 on multiple mobile frames 500 all rotate, thereby driving the multiple mobile frames 500 to slide synchronously and equidistantly, thereby equidistantly changing the distance between two adjacent mobile frames 500, and the multiple mobile frames 500 simultaneously drive the circulating components 600 thereon and the limiting guide mechanism 800 on one side thereof to move equidistantly; The plurality of circulation components 600 drive the pressure control mechanism 900 thereon to move equidistantly. The circulation components 600 and the pressure control mechanism 900 can effectively press and convey packaging boards of different specifications by moving equidistantly, so that they can stably and efficiently enter the feed end of the printing press, meet the conveying requirements of the device for diversified packaging boards, significantly improve the conveying efficiency and conveying quality of the device, and thus improve the printing efficiency of the printing press; the limiting guide mechanism 800 can effectively limit and guide the side walls of packaging boards of different specifications by moving equidistantly, avoid the deviation of the packaging boards during the conveying process, ensure the accuracy of the angle when the packaging boards enter the printing press, improve the printing quality of the packaging boards, and reduce the printing waste rate; The above is the working principle of the position limiting conveying device of the packaging container printing machine.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
