[0034] in, Figure 1 The reference direction coordinate system of the embodiment of the present application is given. Figure 1 The embodiment of the present application is described with reference to the direction shown.

[0035] The embodiment of the present application provides a paper feeding device, see Figures 1 to 7 , including a conveying mechanism 100 and a paper suction mechanism 200, the conveying mechanism 100 includes a supporting assembly 110, a first conveying assembly 120 and a pushing component 130, the supporting assembly 110 is rotatably connected to the end of the first conveying assembly 120 to support or release the cardboard, the pushing component 130 can move the cardboard from the first conveying assembly 120 to the supporting assembly 110, the paper suction mechanism 200 is arranged downstream of the conveying mechanism 100, the paper suction mechanism 200 includes a paper suction bin 210, a suction assembly 220 and a second conveying assembly 230, a paper inlet is opened at the top of the paper suction bin 210, the supporting assembly 110 is located above the paper inlet, the paper suction bin 210 is used to store the cardboard, the suction assembly 220 is located below the paper suction bin 210, and the suction assembly 220 can suck the cardboard and place the cardboard on the second conveying assembly 230.

[0036] When the paper feeding device is in use, a stack of paperboards is placed on the first conveying assembly 120, and the stack of paperboards is transported to a designated position along the first conveying assembly 120. The pushing component 130 moves the stack of paperboards transported on the first conveying assembly 120 to the supporting assembly 110, and controls the supporting assembly 110 to rotate relative to the first conveying assembly 120 to release the stack of paperboards. The stack of paperboards falls into the paper suction bin 210, and the suction assembly 220 sucks a cardboard at the bottom of the stack of paperboards and places the cardboard on the second conveying assembly 230, so as to separate a single cardboard from a stack of paperboards and transport them. The paper feeding device can reduce the number of manual paper placements and realize efficient transportation of paperboards. The paper feeding device can solve the problem that the paperboard bin space is limited and multiple manual paper placements are required, and solves the problem that the existing swing arm type paper suction and paper placement stroke is long, resulting in low efficiency of paperboard loading.

[0037] It can be understood that the support assembly 110 is a support plate, which is controlled to rotate by a cylinder. In the supporting state, the support plate holds up a stack of cardboards. In the flipping state, the support plate supports the stack of cardboards and falls into the paper suction bin 210.

[0038] In some embodiments, a paper loading mechanism 300, a paper pushing mechanism 400 and a paper feeding mechanism 500 are sequentially arranged upstream of the conveying mechanism 100 along the conveying direction of the cardboard. The paper loading mechanism 300 includes a first chain 320 and a plurality of first conveying rollers 310 arranged at intervals along the conveying direction of the cardboard. The first conveying roller 310 is provided with a first sprocket 330 meshing with the first chain 320. The paper loading mechanism 300, the paper pushing mechanism 400 and the paper feeding mechanism 500 can prevent multiple stacking of cardboards and reduce the number of manual paper placements.

[0039] In some embodiments, the paper pushing mechanism 400 includes a second chain 410 and a plurality of second conveying rollers 420 arranged at intervals. The second conveying roller 420 is arranged in parallel with the first conveying roller 310. The second conveying roller 420 is located downstream of the first conveying roller 310. The second conveying roller 420 is provided with a second sprocket 430 meshing with the second chain 410. The second sprocket 430 is driven to move by installing a motor. The movement of the second sprocket 430 drives the second conveying roller 420 to move, so that the paperboard moves forward.

[0040] In some embodiments, the paper feeding mechanism 500 includes a third conveying roller 510, a pushing assembly 520 and a slide rail 530 arranged axially along the second conveying roller 420. The third conveying roller 510 is arranged vertically to the second conveying roller 420. A slider 540 cooperating with the slide rail 530 is provided at the bottom of the pushing assembly 520. The pushing assembly 520 can move the cardboard on the second conveying roller 420 to the third conveying roller 510, that is, the paper feeding mechanism 500 and the paper loading mechanism 300 are arranged vertically, and the position between the paper feeding mechanism 500 and the paper loading mechanism 300 is reserved for using a robot to load the cardboard.

[0041] It is understandable that the paper pushing mechanism 400 can be provided with a photoelectric sensing device, which is connected to the second conveying roller 420 and is provided with a side guard plate. When a stack of cardboard reaches the side guard plate, the photoelectric sensing device senses the cardboard, stops the rotation of the second conveying roller 420, and then pushes the component 520 to push the stack of cardboard flatly to the paper feeding mechanism 500.

[0042] In some embodiments, the pushing assembly 520 includes a support rod 522 and a push plate 521 located above the second conveying roller 420, the top end of the support rod 522 is connected to the push plate 521, the bottom end of the support rod 522 is connected to the slider 540, and a first channel 421 for the support rod 522 to move is formed between the spaced second conveying rollers 420.

Two conveyor belts 121 are provided, and a second channel 123 for the first moving part to move is formed between the two conveyor belts 121. The pushing part 130 is rotatably connected to the first moving part, and the first moving part is connected to the output end of the cylinder 122.

[0044] In some embodiments, the suction component 220 includes a second moving part that can move in the height direction, and a vacuum suction cup is provided on the top of the second moving part. A block 211 for lifting the cardboard is provided on the inner wall of the paper suction bin 210, and the vacuum suction cup can drive the cardboard to escape from the block 211. The vacuum suction cup is connected to a vacuum generator, and an electromagnetic valve is provided to change the valve core so that the vacuum generator generates a vacuum, so that the vacuum suction cup has a certain adsorption force, and the bottom cardboard of a stack of cardboards is sucked. This cardboard is deformed under the action of the cardboard, gets rid of the comfort of the block 211 and escapes from the paper suction bin 210, and then the vacuum suction cup releases the adsorption of the cardboard, so that the cardboard falls on the conveyor belt 121 and is transported to the downstream process.

[0045] In some embodiments, the suction assembly 220 includes a synchronous belt and a synchronous wheel meshed with the synchronous belt. The second moving component is fixedly arranged on the synchronous belt. The synchronous belt can drive the second moving component to rise and fall, thereby driving the vacuum suction cup to rise and fall, and realizing the picking and placing of a single cardboard.

[0046] In some embodiments, a paper feeding mechanism 600 is provided downstream of the paper suction mechanism 200.

The end of the conveying chain 610 extends to the location of the bottle loading station. After the conveyor belt 121 transports a single cardboard to the conveying chain 610, the limiting hook 630 ensures the stable transportation of the single cardboard and smoothly hooks the cardboard to the cardboard loading station.

[0047] The present application also provides a paper feeding method using the above-mentioned paper feeding device, comprising the following steps: a plurality of stacks of paperboards fall onto a paper loading mechanism 300 along a paperboard conveying direction and are transferred to a paper pushing mechanism 400;

[0048] The pushing component 520 pushes a stack of paperboards flatly onto the paper feeding mechanism 500;

[0049] The paper feeding mechanism 500 conveys a stack of paperboards to the conveying mechanism 100;

[0050] The pushing component 130 moves a stack of cardboards transported by the first conveying component 120 to the supporting component 110;

[0051] The support assembly 110 rotates relative to the first conveying assembly 120 to release a stack of paperboards, and the stack of paperboards falls into the paper suction bin 210;

[0052] The suction component 220 sucks a cardboard at the bottom of a stack of cardboards and places the cardboard on the second conveying component 230;
