[0030] A cardboard printing and loading device according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0031] Reference Figure 1 , the utility model aims to provide an embodiment of a cardboard printing and feeding device.

[0032] A cardboard printing and feeding device according to an embodiment of the utility model comprises a conveying mechanism, a lifting mechanism and a feeding mechanism.

[0033] The conveying mechanism includes a first conveying roller set 100 and a first motor 110 for driving the first conveying roller set 100 for conveying. The first conveying roller set 100 is used to convey the stacked cardboards.

[0034] The lifting mechanism includes a lifting frame 120 , a second conveying roller set 130 arranged on the top of the lifting frame 120 , and a second motor 140 driving the second conveying roller set 130 to convey. The second conveying roller set 130 is used to receive the cardboard from the first conveying roller set 100 .

[0035] Therefore, the first motor 110 is used to drive the first conveyor roller group 100 to rotate, and the first conveyor roller group 100 conveys the stacked cardboards to the second conveyor roller group 130. The top of the second conveyor roller group 130 supports the stacked cardboards. The lifting frame 120 is used to lift the second conveyor roller group 130 to a suitable height to facilitate the transfer of the top layer of cardboards to the feed port of the printing press, thereby providing a basis for cardboard loading and improving the degree of automation of the equipment.

[0036] The feeding mechanism includes a material blocking assembly and a material pushing assembly located above the second conveying roller, and a bracket 150 connecting the material blocking assembly and the material pushing assembly. Figure 1 and Figure 2 The material blocking assembly includes a baffle 160 and a first cylinder 170 that drives the baffle 160 to move horizontally. The baffle 160 is used to abut against one side of the stacked cardboard. The material pushing assembly includes a push plate 180 and a second cylinder 190 that drives the push plate 180 to move horizontally. The stacked cardboard is accommodated between the push plate 180 and the baffle 160. In the vertical direction, the height of the bottom of the push plate 180 is greater than the height of the top of the baffle 160.

[0037] After the top layer of cardboard on the second conveyor roller set 130 is lifted to a suitable height, the first cylinder 170 is used to drive the baffle 160 close to the side of the stacked cardboard, and the stacked cardboard enters the space between the baffle 160 and the push plate 180. In addition, the second cylinder 190 is used to drive the push plate 180 to move horizontally. The push plate 180 can push the multiple cardboards on the upper layer to the feed end of the printing press. The baffle 160 can prevent the cardboards on the lower layer from moving and prevent the stacked cardboards from collapsing. In this way, the cardboards are loaded instead of being loaded by the operator, which improves the loading efficiency and reduces the cost of cardboard printing.

[0038] In some embodiments of the present invention, the pushing assembly further includes a third cylinder 200 for driving the second cylinder 190 to move up and down. The piston rod of the third cylinder 200 is provided with a connecting plate 210 , which is connected to the second cylinder 190 .

[0039] Therefore, when the stacked cardboards are transferred from the first conveying roller set 100 to the second conveying roller set 130, the third cylinder 200 drives the second cylinder 190 to rise, so that the push plate 180 rises to a certain height to avoid interference between the push plate 180 and the cardboards.

[0040] During loading, the third cylinder 200 drives the second cylinder 190 to descend, so that the second cylinder 190 can push the push plate 180 to move and push the paperboard.

[0041] In some embodiments of the present invention, a guide rod 220 is provided on the top of the connecting plate 210, and a guide sleeve 230 is provided on the bracket 150. The guide rod 220 and the guide sleeve 230 are connected to each other in an upward and downward sliding manner.

[0042] When the second cylinder 190 drives the push plate 180 to move, the second cylinder 190 will generate a horizontal force on the third cylinder 200. The cooperation between the guide rod 220 and the guide sleeve 230 can reduce the external force on the third cylinder 200 and reduce the deformation problem of the piston rod of the third cylinder 200.

[0043] In some embodiments of the present invention, the second conveying roller group 130 is provided with a through-beam photoelectric sensor, which has a transmitter 240 and a receiver 250. The transmitter 240 and the receiver 250 are used to detect stacked cardboards. Therefore, when the stacked cardboards enter the area between the transmitter 240 and the receiver 250, the through-beam photoelectric sensor detects the cardboards and feeds back the signal to the relevant control system, causing the second conveying roller group 130 to stop conveying and wait for loading.

[0044] In some embodiments of the present invention, a transition platform 260 is provided on the side of the second conveying roller set 130 away from the first conveying roller set 100 , and a plurality of rollers 270 are provided on the top of the transition platform 260 , and the rollers 270 are used to support the stacked cardboards.

[0045] Therefore, the push plate 180 can push the cardboard toward the transition platform 260 , and the cardboard moves on the rollers 270 , which can reduce the friction between the cardboard and the transition platform 260 , so that the cardboard can smoothly enter the feed port of the printing press.

[0046] In some embodiments of the present invention, referring to Figure 3A first vertical plate 280 and a second vertical plate 290 connected to one side of the first vertical plate 280 are provided on the side of the bracket 150 away from the second conveying roller group 130. The second vertical plate 290 is arranged away from the second conveying roller group 130. The first cylinder 170 is connected to the second vertical plate 290. Therefore, the first cylinder 170 is arranged away from the second conveying roller group 130. The first cylinder 170 can drive the baffle 160 to move, so that the baffle 160 is away from the second conveying roller group 130, so that the push plate 180 can push the bottom cardboard to the feed port of the printing press.

[0047] In some embodiments of the present invention, two material blocking assemblies are provided, and the two material blocking assemblies are respectively provided on both sides of the second conveying roller set 130 .

[0048] By blocking the stacked cardboards with two blocking assemblies, the area of the baffle 160 can be reduced, which is beneficial to reducing the space occupied by the blocking assemblies and at the same time ensures that the blocking assemblies have sufficient force to block the cardboards.

[0049] In some embodiments of the present invention, referring to Figure 4 and Figure 5 The lifting mechanism also includes a base plate 300, and a first rotating frame 310 and a second rotating frame 320 are hinged to each other between the base plate 300 and the lifting frame 120, and a power part that drives the first rotating frame 310 and the second rotating frame 320 to rotate. One side of the first rotating frame 310 is slidably connected to the top of the base plate 300, and the other side of the first rotating frame 310 is hinged to the bottom of the lifting frame 120. One side of the second rotating frame 320 is hinged to the top of the base plate 300, and the other side of the second rotating frame 320 is slidably connected to the bottom of the lifting frame 120.

[0050] It is understandable that the first rotating frame 310 and the second rotating frame 320 are hinged to form an X shape. The power member drives the first rotating frame 310 and the second rotating frame 320 to rotate relative to each other, so that the lifting frame 120 can be lowered to a lower position, so that the cardboards can be stacked higher.

[0051] In some embodiments of the present invention, the power component is a hydraulic cylinder 330, one end of the hydraulic cylinder 330 is hinged to the base plate 300, and the other end of the hydraulic cylinder 330 is hinged to the second rotating frame 320. Therefore, the hydraulic cylinder 330 is used to drive the second rotating frame 320 to rotate, so that the first rotating frame 310 rotates synchronously, thereby enabling the lifting frame 120 to be raised and lowered.

[0052] In some embodiments of the present invention, referring to Figure 4 and Figure 5 The second rotating frame 320 is provided with a guide wheel 340 , and a limiting groove 350 is provided at the bottom of the lifting frame 120 , and the guide wheel 340 moves along the limiting groove 350 .

[0053] It should be noted that the first rotating frame 310 may also be provided with a guide wheel 340 , and the top of the base plate 300 may also be provided with a limiting groove 350 , and the guide wheel 340 moves along the limiting groove 350 .

[0054] Therefore, the first rotating frame 310 and the second rotating frame 320 rotate smoothly, ensuring that the lifting frame 120 can be lifted and lowered smoothly.
