Description

Technical Field

[0001] This utility model relates to the field of printing technology, and in particular to a limiting mechanism for a paper collection area. Background Technology

[0002] After the printed text and patterns are cut by the slitting device, the sheets are transported one by one to the lifting plate in the collection area and stacked. When the top of the stacked sheets exceeds the table of the slitting device, the lifting plate lowers the sheets so that the top of the sheets is below the table of the slitting device. This allows the sheets cut later to be stacked on top of the sheets cut earlier. The collection area is usually equipped with baffles. When the sheets move from the slitting device to the lifting plate in the collection area, the baffles block each sheet, ensuring that the longitudinal distance from the position of each sheet on the lifting plate to the slitting device is the same. This allows the sheets to be stacked and kept aligned front to back. Although the sheets can be aligned front to back, they cannot be aligned left to right. If too many sheets are stacked, it is more troublesome to adjust them. If the sheets are not aligned front to back and left to right, it will affect the bundling and packaging of the sheets. Utility Model Content

[0003] The purpose of this invention is to provide a limiting mechanism for the paper collection area to solve the above-mentioned problems.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A limiting mechanism for a paper collection area includes a mounting frame with a lifting plate between its two sides. The mounting frame has a first moving mechanism and a second moving mechanism on its side. It also includes a first mounting rod and a second mounting rod. The first mounting rod is horizontally slidably connected to the side of the mounting frame via a first connector, and the second mounting rod is slidably connected to the mounting frame via a second connector. The first and second mounting rods are located above the lifting plate. The first moving mechanism is connected to the first connector of the second mounting rod, and the second moving mechanism is connected to the second connector. The first mounting rod is fixedly connected to a first connecting plate, which has a lifting mechanism. The lifting mechanism is connected to a moving lever, which is vertically slidably connected to the first connecting plate. The moving lever is horizontally slidably connected to multiple baffles, with a first fixing member between each baffle and the moving lever. The second mounting rod is slidably connected to two second connecting plates, each with a second fixing member between it and the second mounting rod. Each second connecting plate has a pushing mechanism connected to a push plate.

[0005] Using the above technical solution, the mounting frame is equipped with a slitting device and a conveying device. Based on the length and width of the slitting paper, the first moving mechanism drives the first mounting rod to move longitudinally via the first connecting piece. The first mounting rod drives the first connecting plate to move, and the first connecting plate drives the lifting mechanism, the moving lever, and multiple baffles away from the mounting frame. Then, the multiple baffles on the moving lever move laterally, positioning them between the two straight lines representing the left and right sides of the paper. The baffles on the moving lever are then fixed by the first fixing piece on each baffle. Relative to the second mounting rod, the two connecting plates move laterally, driving their respective upper pushing mechanisms and push plates to move laterally, adjusting the distance between the two push plates so that the paper can enter between them. Then, the second moving mechanism drives the second mounting rod to move longitudinally via the second connecting piece. The second mounting rod drives the two second connecting plates to move, and the two second connecting plates drive their respective upper pushing mechanisms and push plate longitudinal moving mechanisms, positioning the two push plates between the two straight lines representing the front and rear sides of the paper. After the slitting device cuts the paper with printed patterns and text, the paper is conveyed by the conveying device to the lifting plate of the mounting frame, where the paper is positioned between the two push plates. In between, the moving mechanism repeatedly drives the lifting mechanism and multiple baffles to approach the tail of the paper, making the lower part of the baffles contact the tail of the paper. Two pushing mechanisms then push their respective connected push plates to move, bringing the two push plates close to the left and right sides of the paper. Next, two connecting plates move laterally, causing the two connecting plates to contact the left and right sides of the paper. The pushing mechanism then moves the two push plates back to separate from the left and right sides of the paper. The two push plates are then fixed in place by the fixing component. The conveying mechanism then transports the cut paper from behind onto the lifting plate. The moving paper is stopped by the baffles. The paper is blocked and falls onto the top of the previous sheets, and so on, conveying the paper to the lifting plate. When the paper on the lifting plate is stacked to a certain height, two pushing mechanisms push their respective connected push plates to move. The two push plates exert force on the left and right sides of the stacked paper, so that the left and right sides of each sheet are aligned with the left and right sides of the bottom sheet. This process continues, so that the paper is neatly stacked on the lifting plate. When the paper on the lifting plate is stacked high, the lifting mechanism drives the baffle to rise, so that the baffle moves away from the back of the paper, and then the paper can be removed from the lifting plate.

[0006] Preferably, the moving mechanism consists of a sprocket and chain assembly and a motor. The sprocket and chain assembly comprises two pairs, which are horizontally connected to both sides of the mounting frame. The sprockets of the sprocket and chain assembly are rotatably connected to the mounting frame and located at the same end. A connecting shaft connects the two sprockets in different pairs of sprocket and chain assemblies. The output shaft of the motor is fixedly connected to the sprocket at one end of the connecting shaft. The chains of the two pairs of sprocket and chain assemblies are each connected to a connector.

[0007] Using the above technical solution, motor 1 drives the sprocket connected to it to rotate. The rotating sprocket drives the sprockets on the same end but different pairs of sprocket chain assemblies to rotate through the connecting shaft. The rotating sprocket drives the sprockets on the same group of sprocket chain assemblies to rotate through the chain. The rotating chain drives the mounting rod to move longitudinally through the connector. The mounting rod drives the connecting plate to move. The connecting plate drives the lifting mechanism, the moving bar and multiple baffles to move longitudinally.

[0008] Preferably, the first fixing component and the second fixing component are bolt one and bolt two, respectively. Bolt one passes through the part of the baffle that is connected to the moving bar. Bolt one is threadedly connected to the baffle and the end of bolt one abuts against the moving bar. Bolt two passes through the part of the connecting plate two that is connected to the mounting rod two. Bolt two is threadedly connected to the connecting plate two and the end of bolt two abuts against the mounting rod two.

[0009] Using the above technical solution, tightening bolt one causes its end to press against the moving bar, thereby fixing the baffle on the moving bar. Similarly, tightening bolt one in the opposite direction reduces the force between its end and the moving bar, allowing the baffle to move along the moving bar. Tightening bolt two on the connecting plate causes its end to press against the mounting rod two, thereby fixing the connecting plate on the mounting rod two. Similarly, tightening bolt two in the opposite direction allows the connecting plate to move along the mounting rod two.

[0010] Preferably, the lifting mechanism is a cylinder, which is vertically fixedly connected to the connecting plate, and the moving lever is fixedly connected to the output shaft of the cylinder.

[0011] Using the above technical solution, the cylinder's output shaft extends or retracts, driving the moving lever to rise or fall.

[0012] Preferably, the pushing mechanism is cylinder two, which is horizontally fixedly connected to connecting plate two, and the push plate is fixedly connected to the output shaft of cylinder two.

[0013] Using the above technical solution, the output shaft of cylinder 2 extends or retracts, driving the push plate to move back and forth laterally.

[0014] Preferably, two horizontal guide rods are fixedly connected to the left and right sides of the mounting frame, respectively. The two guide rods on each side of the mounting frame are guide rod one and guide rod two, respectively. Connector one and connector two are slide plate one and slide plate two, respectively. There are two slide plates one and two slide plates two. The two slide plates one are connected to the chains of the two sets of sprocket and chain assemblies one, respectively. The two slide plates two are connected to the chains of the two sets of sprocket and chain assemblies two, respectively. Slide plate one is slidably connected to guide rod one located on the same side of the mounting frame, and slide plate two is slidably connected to guide rod two located on the same side of the mounting frame. The two ends of mounting rod one are fixedly connected to the two slide plates one, respectively. The two ends of mounting rod two are fixedly connected to the two slide plates two, respectively.

[0015] Using the above technical solution, the two pairs of sprocket and chain assemblies 1 respectively drive the two slide plates 1 to move along their respective connected guide rods 1, and the two slide plates 1 drive the mounting rod 1 to move; the two pairs of sprocket and chain assemblies 2 respectively drive the two slide plates 2 to move along their respective connected guide rods 2, and the two slide plates 2 drive the mounting rod 2 to move.

The sprockets of the sprocket and chain assemblies 10 are rotatably connected to the mounting frame 1, located at the same end, and connected to two sprockets in different pairs of sprocket and chain assemblies 10 by a connecting shaft 12. A motor 11 is fixedly connected to the side of the mounting frame 1, and the output shaft of the motor 11 is fixedly connected to the sprocket at the end of the connecting shaft 12. The chains of the two sprocket and chain assemblies 10 are respectively connected to sliding plates 21. The mounting frame 1 has two sprocket and chain assemblies 13 connected to its two sides. The sprockets of the sprocket and chain assemblies 13 are rotatably connected to the mounting frame 1. The two sprockets in the sprocket and chain assemblies 13, which are not in the same pair, are connected by a connecting shaft 12. The output shaft of the motor 14 is fixedly connected to the sprocket at one end of the connecting shaft 12. The chains of the two sprocket and chain assemblies 13 are respectively connected to slide plates 22. Two horizontal guide rods are fixedly connected to the left and right sides of the mounting frame 1. The two guide rods on each side of the mounting frame 1 are guide rod 19 and guide rod 20. Slide plate 21 is slidably connected to guide rod 19 on the same side of the mounting frame 1; slide plate 22 is slidably connected to guide rod 20 on the same side of the mounting frame 1.

[0020] See Figure 1 , Figures 2 to 7 It also includes mounting rod 3 and mounting rod 4. The two ends of mounting rod 3 are fixedly connected to two sliding plates 21, and the two ends of mounting rod 4 are fixedly connected to two sliding plates 22. Mounting rod 3 and mounting rod 4 are located above the lifting plate 2. Mounting rod 3 is fixedly connected to two connecting plates 5. A vertical cylinder 17 is fixedly connected to the connecting plate 5. The output shaft of cylinder 17 is fixedly connected to a moving rod 6. The two ends of the moving rod 6 are vertically slidably connected to the two connecting plates 5, and the moving rod 6 is horizontally slidably connected to multiple baffles 7. Bolts 15 pass through the baffles 7 where they connect to the moving rod 6. Bolts 15 are threadedly connected to the baffles 7, and the ends of bolts 15 abut against the moving rod 6. Mounting rod 24 has two sliding connection plates 28. Bolt 216 passes through the part of the connection plate 28 that connects to mounting rod 24. Bolt 216 is threaded to connection plate 28. The end of bolt 216 abuts against mounting rod 24. Each connection plate 28 is fixedly connected to a horizontal cylinder 218. The output shaft of cylinder 218 is fixedly connected to a push plate 9.

[0021] Working principle: The mounting frame 1 is equipped with a slitting device and a conveying device. Based on the length and width of the slit paper, motor 11 drives the sprocket connected to it to rotate. The rotating sprocket drives the sprockets on the same end of the sprocket chain assembly 10, but on different pairs of sprockets, to rotate via the connecting shaft 12. The rotating sprocket drives the sprockets on the same set of sprocket chain assembly 10 to rotate via the chain. The rotating chain drives the mounting rod 3 to move longitudinally via the sliding plate 21. The mounting rod 3 drives the connecting plate 5 to move, and the connecting plate 5 drives the cylinder 17, the moving lever 6, and the baffle 7 away from the mounting frame 1. Then, each baffle 7 on the moving lever 6 is moved laterally so that the baffle 7 is positioned between the two straight lines containing the left and right edges of the paper. Finally, the bolts 15 on each baffle 7 are tightened so that the ends of the bolts 15 press against the moving lever 6, thereby fixing the baffle 7 to the moving lever 6.

[0022] Then, the two connecting plates move laterally relative to the mounting rod 24. The two connecting plates drive the upper cylinder 218 and push plate 9 to move laterally, adjusting the distance between the two push plates 9 so that the paper can enter between the two push plates 9. Then, the motor 214 drives the sprocket and chain assembly 213 to run. The chain of the sprocket and chain assembly 213 pulls the slide plate 22 to move longitudinally along the guide rod. The slide plate 22 drives the mounting rod 24 to move longitudinally. The mounting rod 24 drives the two connecting plates 28 to move. The two connecting plates 28 respectively drive the upper cylinder 218 and push plate 9 to move longitudinally, so that the two push plates 9 are located between the two straight lines on the front and rear sides of the paper.

[0023] After the slitting device cuts the paper printed with patterns and text, the paper is conveyed by the conveying device to the lifting plate 2 of the mounting frame 1. The paper is positioned between two push plates 9. The sprocket and chain assembly 10 then drives the cylinder 17 and multiple baffles 7 to approach the tail of the paper, making the lower part of the baffles 7 contact the tail of the paper. The output shafts of the two cylinders 18 extend and push their respective connected push plates 9 to move, so that the two push plates 9 approach the left and right sides of the paper respectively. Then, the two connecting plates 28 move laterally, causing the two connecting plates 28 to drive the two push plates 9 to contact the left and right sides of the paper respectively. The output shafts of the cylinders 18 retract, causing the two push plates 9 to return and separate from the left and right sides of the paper. The bolts 16 on the connecting plates are tightened, so that the ends of the bolts 16 abut against the mounting rod 4, thereby fixing the connecting plates and push plates 9 in place. The conveying mechanism then conveys the cut paper from the rear onto the lifting plate 2. The moving paper is blocked by the baffles 7 and falls on top of the previous paper. This process continues until the paper is conveyed onto the lifting plate 2. When the paper on the lifting plate 2 is stacked to a certain height, the two cylinders 18 push their respective connected push plates 9 to move. The two push plates 9 exert force on the left and right sides of the stacked paper, so that the left and right sides of each paper are aligned with the left and right sides of the bottom paper. Every once in a while, the two cylinders 18 drive the two push plates 9 to push the two sides of the paper down in turn, so that the paper is neatly stacked on the lifting plate 2. When the paper on the lifting plate 2 is stacked high, the output shaft of the cylinder 17 drives the baffle 7 to rise, so that the baffle 7 moves away from the back of the paper, and then the paper can be transported away from the lifting plate 2.
