Description

Technical Field

[0001] This utility model relates to the field of printing technology, and in particular to a feeding device for paper processing. Background Technology

[0002] A single sheet of printed paper is cut into multiple individual sheets. After cutting, the paper needs to be laminated to increase its protective properties, making it more waterproof, wear-resistant, and tear-resistant. During the lamination process, workers first place a stack of cut paper on the lifting plate of the processing equipment. The lifting plate lifts the paper, bringing it closer to the worktable. Then, workers manually place the paper onto the conveyor mechanism of the equipment, typically a conveyor belt with rollers and pressure plates above it. The paper is placed between the rollers and the conveyor belt, where the rollers hold it in place. The conveyor belt then transports the paper to the processing area for processing. The pressure from the rollers keeps the paper flat as it enters the processing area, allowing for better processing. After a certain number of sheets have been processed, the number of sheets on the lifting plate decreases, increasing the distance between the paper and the worktable. The lifting plate then lifts the paper again, bringing it closer to the worktable.

[0003] Because the paper surface is smooth and has no gripping points, it is not easy to pick up the sheets one by one. Moreover, the paper is relatively thin, and if workers use too much force when picking up the paper, it can easily cause wrinkles, affecting product quality. Utility Model Content

[0004] The purpose of this invention is to provide a feeding device for paper processing to solve the above-mentioned problems.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A feeding device for paper processing includes a worktable with a conveying mechanism. A lifting mechanism is located between the two side walls at the end of the worktable, and the lifting mechanism is connected to a placement plate. A limiting mechanism is located on the side of the worktable above the placement plate. A moving mechanism is also located on the side of the worktable, connected to a connecting rod. A horizontal guide tube is fixedly connected to the connecting rod, and multiple vertical suction tubes are fixedly connected to the guide tube. An air pump is located on the side of the worktable, and a connecting pipe is provided between the air pump and the guide tube. The device also includes a rotating roller and... A support rod is provided, with the rotating roller and the support rod located between the two sides of the worktable. The rotating roller is located in front of the guide tube, and both ends of the rotating roller are rotatably connected to the two sides of the worktable. A drive mechanism is fixedly connected to the worktable, and the drive mechanism is connected to the rotating roller. Both ends of the support rod are fixedly connected to the worktable, and a mounting plate is fixedly connected to the support rod. The mounting plate is provided with a rotating mechanism, and a connecting plate is hinged to the mounting plate. The rotating mechanism is connected to the connecting plate, and a horizontal rotating rod is rotatably connected to the connecting plate. The rotating rod is located above the rotating roller, and a transmission component is provided between the rotating rod and the rotating roller. Multiple pressure rollers are fixedly connected to the rotating rod.

[0007] Using the above technical solution, the worker places a stack of cut paper on the placement plate. The lifting mechanism raises the placement plate and the paper on top of it, bringing the top layer of paper close to the workbench surface. The paper is positioned below the suction tube, and a limiting device restricts the left, right, and rear sides of the paper. The air pump starts, drawing air out of the guide tube and suction tube, creating negative pressure. The suction tube then lifts the paper below it. The rotating mechanism drives the connecting plate to rotate, which in turn drives the rotating rod to revolve. The rotating rod then drives the pressure roller to revolve. The transmission components between the rotating rod and the rotating roller separate, moving the pressure roller away from the rotating roller. The moving mechanism, via the connecting rod, moves the guide tube and the paper it holds. The guide tube moves the paper between the pressure roller and the rotating roller. The rotating mechanism, via the connecting plate, drives the rotating rod and pressure roller to rotate back, bringing the pressure roller closer to the paper. The pressure is applied to the paper, pressing it onto the rotating roller and separating it from the suction tube. The pressure roller and rotating roller press down on the top and bottom surfaces of the paper, respectively. The drive mechanism rotates the rotating roller, which in turn drives a rotating rod to rotate relative to the connecting plate via a transmission component. The rotating rod drives the pressure roller to rotate, and the rotating pressure roller and rotating roller move the paper horizontally between them, allowing the paper to enter the conveying mechanism horizontally. The conveying mechanism then transports the paper to the processing area for processing. After a certain number of papers have been processed, the distance between the paper and the suction tube increases. The lifting mechanism lifts the paper on the placement plate, reducing the distance between the paper and the suction tube. This prevents the distance between the suction tube and the paper from being too large to pick up the paper. The suction makes it easier to pick up the paper, while also avoiding excessive force during the picking process that could cause wrinkles and reduce product quality.

[0008] Preferably, the limiting mechanism includes a guide rod one, a guide rod two, and two limiting plates. The guide rod one and the guide rod two are horizontally located between the two sides of the worktable and above the placement plate. The guide rod one and the guide rod two are located behind the guide tube, the guide rod two is located at the very end of the worktable, and the guide rod one is located in front of the guide rod two. The guide rod one and the guide rod two are fixedly connected to the worktable. The guide rod one passes through the two limiting plates. The limiting plates are slidably connected to the guide rod one. A fixing member is provided between the limiting plates and the guide rod one. Two connecting blocks are slidably connected to the upper part of the guide rod two. A fixing member is provided between the connecting blocks and the guide rod two. Each connecting block is respectively fitted with a movable plate. The guide rod two is located between the movable plate and the fixing member of the connecting block. The movable plate is slidably connected to the connecting block. An elastic baffle is fixedly connected to the movable plate.

[0009] Using the above technical solution, the lifting mechanism drives the placement plate and the paper above the placement plate to rise, so that the paper on the top layer is close to the workbench surface. At the same time, the paper is located between two limiting plates. According to the length and width of the paper, the two connecting blocks move left and right along the guide rod. The two connecting blocks drive the moving plates connected to them to move, so that the two moving plates are located between the two straight lines on the left and right sides of the paper. Then, the two moving plates move back and forth relative to the connecting blocks. The moving plates drive the elastic baffle to abut against the back of the paper. Then, the connecting blocks and moving plates are fixed by the fixing parts on the connecting blocks. Then, the limiting plates on both sides of the paper are moved so that the two limiting plates contact the left and right sides of the paper respectively. Then, the limiting plates are fixed by the fixing parts on each limiting plate.

[0010] Preferably, the fixing component is a bolt, the limiting plate is integrally formed with a sliding sleeve, the guide rod one passes through the sliding sleeve of the limiting plate, the bolt on the limiting plate passes through the sliding sleeve, the bolt is threadedly connected to the sliding sleeve, and the end of the bolt on the sliding sleeve abuts against the guide rod one, the bolt on the connecting block passes through the connecting block and is threadedly connected to the connecting block, the end of the bolt on the connecting block abuts against the guide rod two, the guide rod two is located between the bolt on the connecting block and the moving plate, and the moving plate is in contact with the guide rod two.

[0011] Using the above technical solution, tightening the bolts on the limiting plate sliding sleeve moves the bolt ends away from the first guide rod, reducing the force between the bolt ends and the first guide rod. Then, the limiting plate can be moved left and right along the first guide rod. Similarly, tightening the bolts on the limiting plate sliding sleeve in the opposite direction makes the bolt ends press against the first guide rod, thus fixing the limiting plate. Tightening the bolts on the connecting block causes the bolt ends and the moving plate to exert forces on both sides of the second guide rod, causing the bolt ends and the moving plate to clamp the guide rod, thus fixing the moving plate and the connecting block. Similarly, tightening the bolts on the connecting block in the opposite direction reduces the force between the bolt ends and the moving plate on the second guide rod, allowing the connecting block and the moving plate to move left and right along the second guide rod, and simultaneously allowing the moving plate to move back and forth relative to the connecting block.

[0012] Preferably, the moving mechanism is a cylinder, which is horizontally fixedly connected to the side of the worktable. One end of the connecting rod is fixedly connected to the output shaft of the cylinder, and the other end of the connecting rod is slidably connected to the side of the worktable.

[0013] Using the above technical solution, the output shaft of cylinder one extends to push the connecting rod to move, and the connecting rod drives the guide tube to move.

[0014] Preferably, the rotating mechanism is a second cylinder, which is hinged to the mounting plate, and the output shaft of the second cylinder is hinged to the connecting plate.

[0015] Using the above technical solution, the output shaft of cylinder two extends and pushes the connecting plate to rotate. The connecting plate drives the rotating rod to revolve, and the rotating rod drives the pressure roller to revolve. The rotating rod and the pressure roller move away from the rotating roller, and the transmission components between the rotating rod and the rotating roller are separated. Similarly, the output shaft of cylinder two retracts and pulls the connecting plate to rotate back. The connecting plate drives the rotating rod and the pressure roller to return. The pressure roller moves closer to the rotating roller, and the transmission components between the rotating rod and the rotating roller are connected.

[0016] Preferably, the transmission component is a gear, and gears are fixedly connected to the ends of the rotating rod and the rotating roller, with the gear at the end of the rotating roller meshing with the gear at the end of the rotating rod.

[0017] Using the above technical solution, the rotating mechanism drives the rotating rod to revolve through the connecting plate. The rotating rod moves away from the rotating roller, and the gear at the end of the rotating rod separates from the gear at the end of the rotating roller. The rotating mechanism drives the rotating rod to approach the rotating roller through the connecting plate. The gears of the rotating rod and the rotating roller mesh, and the driving mechanism drives the rotating roller to rotate. The rotating roller drives the rotating rod to rotate through the meshing gears, and the rotating rod drives the pressure roller to rotate. Attached Figure Description

[0030] See Figure 1 , Figure 2 , Figure 5 and Figure 7 A horizontal cylinder 22 is fixedly connected to the side of the workbench 1. A slider 1 is fixedly connected to the output shaft of the cylinder 22. The slider 1 is horizontally slidably connected to the side of the workbench 1.

The air pump 6 is connected to the conduit 4 through a connecting pipe 7.

[0031] See Figure 1 , Figure 2 , Figure 4 and Figure 6It also includes a rotating roller 8 and a support rod 9. The rotating roller 8 and the support rod 9 are located between the two sides of the worktable 1. The rotating roller 8 is located in front of the guide tube 4. The two ends of the rotating roller 8 are rotatably connected to the two sides of the worktable 1. The worktable 1 is fixedly connected to a drive mechanism, which can be a motor. The motor is fixedly connected to the side of the worktable 1. The output shaft of the motor is connected to the rotating roller 8 through a synchronous belt and synchronous pulley or a chain and sprocket.

The gears 24 at the ends of the rotating roller 8 and the rotating rod 12 mesh with each other. Multiple pressure rollers 13 are fixedly connected to the rotating rod 12.

[0032] Working principle: The worker places a stack of cut paper on the placement plate 2. The hydraulic cylinder pushes the scissor frame to extend, which lifts the placement plate 2 and the paper on top of it, bringing the topmost paper close to the workbench 1. The paper is positioned below the suction tube 5 and between the two limiting plates 16. Based on the length and width of the paper, the bolts 20 on the sliding sleeves 21 of the limiting plates 16 are tightened, moving the ends of the bolts 20 away from the guide rod 14. This reduces the force between the bolt ends and the guide rod 14. Then, the limiting plates 16 are moved left and right along the guide rod 14, so that the two limiting plates 16 contact the left and right sides of the paper respectively. Then, the bolts 20 on the sliding sleeves 21 of the limiting plates 16 are tightened in the opposite direction, pressing the ends of the bolts 20 against the guide rod 14, thus fixing the limiting plates 16. Tightening the bolts 20 on the connecting block 17 causes the ends of the bolts 20 and the moving plate 18 to press against the guide rod 14. The force of 5 is reduced, and the connecting block 17 and the moving plate 18 are moved left and right along the guide rod 15, so that the two moving plates 18 are moved between the two straight lines on the left and right sides of the paper. Then, the two moving plates 18 are moved back and forth relative to the connecting block 17. The moving plates 18 drive the elastic baffle 19 to abut against the back of the paper. The bolt 20 on the connecting block 17 is turned in the opposite direction, so that the end of the bolt 20 and the moving plate 18 exert force on both sides of the guide rod 15 respectively, so that the end of the bolt 20 and the moving plate 18 clamp the guide rod, thereby fixing the moving plate 18 and the connecting block 17.

[0033] Air pump 6 starts, drawing air out of the conduit 4 and suction tube 5, creating negative pressure within them. The suction tube 5 then picks up the paper below it. The output shaft of cylinder 23 extends, pushing the connecting plate 11 to rotate. The connecting plate 11 drives the rotating rod 12 to revolve, which in turn drives the pressure roller 13 to revolve. The rotating rod 12 and pressure roller 13 move away from the rotating roller 8, and the gear 24 at the end of the rotating rod 12 separates from the gear 24 at the end of the rotating roller 8. The output shaft of cylinder 22 extends, pushing the connecting rod 3 to move. The connecting rod 3 moves the conduit 4 and the paper it holds, with the conduit 4 moving the paper between the pressure roller 13 and the rotating roller 8. The output shaft of cylinder 23 retracts, pulling the connecting plate 11 back. The connecting plate 11 drives the rotating rod 12 and pressure roller 13 back. The pressure roller 13 approaches the paper and applies pressure to it, pressing the paper onto the rotating roller 8, separating the paper from the suction tube 5. The pressure roller 13 and the rotating roller 8 press down on the upper and lower surfaces of the paper respectively. At the same time, the gears 24 of the rotating rod 12 and the rotating roller 8 mesh, and the air pump 6 stops pumping air. The output shaft of cylinder 22 retracts, driving the guide tube 4 back.

[0034] The motor drives the rotating roller 8 to rotate. The rotating roller 8, through meshing gear 24, drives the rotating rod 12 to rotate relative to the connecting plate 11. The rotating rod 12 drives the pressure roller 13 to rotate. The rotating pressure roller 13 and the rotating roller 8 cause the paper between them to move horizontally, allowing the paper to enter between the conveyor belt, rollers, and pressure plates. The conveyor belt transports the paper to the processing area for processing. During the paper transport process, the rollers and pressure plates hold the paper down to prevent it from floating, reducing the contact area between the paper and the conveyor belt. The relative movement between the conveyor belt and the paper affects the paper transport. Simultaneously, the rollers and pressure plates holding the paper down ensures it enters the processing area flat. After processing a certain amount of paper, the distance between the paper and the suction tube 5 increases. The hydraulic cylinder pushes the scissor lift to extend, causing the paper on the placement plate 2 to rise, reducing the distance between the paper and the suction tube 5. This prevents the distance from being too large for the suction tube 5 to effectively pick up the paper. Suction makes it easier to pick up the paper, while avoiding excessive force during the picking process that could cause wrinkles and reduce product quality.
