Description

Technical Field

[0001] This utility model relates to the field of printing technology, and in particular to a paper lifting baffle. 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 to form a paper pile. When the top sheet of the paper pile exceeds the table of the slitting device, the lifting plate moves the paper pile down, so that the top sheet of the paper pile is lower than the table of the slitting device, so that the next sheet of paper can continue to fall onto the paper pile. The paper collection area is usually equipped with baffles. When the paper moves from the slitting device to the lifting plate in the collection area, the baffles will block each sheet of paper, so that the longitudinal distance from the position of each sheet of paper on the lifting plate to the slitting device is the same, so that the paper can be stacked and kept aligned front to back.

[0003] As the paper stack grows taller, the lifting platform lowers it. The baffle can only block the upper part of the paper stack; the paper not blocked by the baffle will shift due to external forces, such as workers accidentally touching it or the lifting platform's unstable descent causing bumps that shift the stack. Since the paper stack is placed on the lifting platform, its initial height is relatively low, resulting in a high support plate. If the baffle is designed to be too long, it will be blocked by the lifting platform, making installation impossible. Conversely, using a shorter baffle will not be enough to block the back of all the paper as the stack grows taller. Utility Model Content

[0004] The purpose of this invention is to provide a paper lifting baffle to solve the above-mentioned problems.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A paper lifting baffle includes a frame with a paper receiving area at the rear end of the frame. A first moving mechanism is located outside the paper receiving area on the frame, and the first moving mechanism is connected to a mounting frame. The mounting frame has two sides slidably connected to the outer sides of the paper receiving area and moves along the longitudinal direction of the frame. A lifting mechanism is located on one side of the mounting frame. Two moving blocks are slidably connected to the top of the mounting frame, and each of the two moving blocks has a baffle passing through it. The baffles are vertically slidably connected to the moving blocks. A second moving mechanism is connected to the lifting mechanism on the side of the mounting frame, and the moving frame is vertically slidably connected to the mounting frame. The upper end of the baffle is slidably connected to the moving frame. A second moving mechanism is located at the top of the moving frame, and the upper ends of the two baffles are connected to the second moving mechanism.

[0006] Using the above technical solution, based on the length and width of the cut paper, the first moving mechanism drives the mounting frame to move longitudinally, the mounting frame drives the lifting mechanism and the moving frame to move, and the moving frame drives the second moving mechanism and two baffles above it to move, so that the baffles move away from or closer to the machine frame. The longitudinal distance from the baffles to the end of the machine frame is adjusted. Then, the second moving mechanism drives the two baffles to move laterally towards each other relative to the mounting frame and the moving frame, so that the two baffles move closer or further apart. The distance between the two baffles is adjusted so that the two baffles are located between the two straight lines on the left and right sides of the paper. The lifting mechanism drives the moving frame to descend, and the moving frame drives the two baffles to descend, so that the bottom ends of the two baffles abut against the surface of the lifting plate. After the paper with printed text and patterns is cut by the slitting device, the conveying mechanism on the machine frame conveys the paper onto the lifting plate. The paper continues to move on the lifting plate and stops after hitting the baffles. The next cut paper... The sheets continue moving to the lifting platform. The moving sheets are stopped by the baffles and fall onto the top of the previous sheets. This process continues, with the sheets stacking on the lifting platform to form a pile. When the pile reaches a certain height, the top sheet extends beyond the slitting device's table. The lifting platform lowers the pile, and simultaneously, the lifting mechanism lowers two baffles, ensuring the bottom of the baffles remains against the lifting platform surface. This allows the baffles to block each sheet in the increased pile height. For every additional length the pile rises, the lifting platform lowers it a corresponding distance, and the baffles follow, blocking the back of each sheet to prevent movement due to external forces. Once the lifting platform has enough sheets, it lowers to its lowest point. The lifting mechanism then raises the baffles, moving their bottom edges above the top sheet of the pile, allowing the sheets to be removed from the lifting platform.

[0007] Preferably, the moving mechanism consists of a sprocket and a chain and a motor. The sprocket and chain are horizontally connected to the side of the paper receiving area of ​​the frame. The sprocket in the sprocket and chain is rotatably connected to the side of the frame. The motor is fixedly connected to the side of the frame. The motor output shaft is fixedly connected to one of the sprockets in the sprocket and chain. One side of the mounting frame is fixedly connected to the chain of the sprocket, and the two sides of the mounting frame are slidably connected to the two sides of the frame, respectively.

[0008] Using the above technical solution, the motor drives the sprocket and chain to rotate, and the chain pulls the mounting frame to move longitudinally relative to the frame.

[0009] Preferably, the lifting mechanism is a lead screw, which is vertically rotatably connected to the side of the mounting frame, and the side of the movable frame is fixedly connected to the lead screw slider.

[0010] Using the above technical solution, the lead screw rotates, and its slider drives the moving frame to rise or fall. The moving frame drives the moving mechanism II and the baffle above it to rise or fall.

[0011] Preferably, the second moving mechanism is a bidirectional lead screw, which is horizontally rotatably connected to the upper part of the moving frame, and the two baffles are respectively fixedly connected to the two sliders of the bidirectional lead screw.

[0012] Using the above technical solution, the bidirectional lead screw rotates, and its two sliders drive the baffles connected to them to move laterally towards each other, so that the two sliders move closer or further apart.

[0013] Preferably, the second moving mechanism is a bidirectional lead screw, which is horizontally rotatably connected to the upper part of the moving frame, and the two baffles are respectively fixedly connected to the two sliders of the bidirectional lead screw.

[0014] Using the above technical solution, the motor drives the sprocket and chain to rotate, and the chain pulls the mounting frame to move longitudinally along the two guide rods relative to the frame. The guide rods limit and guide the mounting frame, increasing the stability of the mounting frame's movement.

[0015] Preferably, a vertical guide rod is fixedly connected to the side of the mounting frame. The guide rod passes through the side of the movable frame and is slidably connected to the movable frame.

[0016] Using the above technical solution, the lead screw rotates, and its slider drives the moving frame to rise or fall along the guide rod 2. The guide rod 2 limits and guides the moving frame, increasing the stability of the moving frame. Attached Figure Description

[0020] See Figures 1 to 3 A paper lifting baffle includes a frame 1 with a paper receiving area at its tail end. A horizontal sprocket chain 6 is connected to the side of the paper receiving area. Horizontal guide rods 10 are fixedly connected to both sides of the frame 1. A sprocket in the sprocket chain 6 is rotatably connected to the side of the frame 1. A motor 7 is fixedly connected to the side of the frame 1, and the output shaft of the motor 7 is fixedly connected to one of the sprockets in the sprocket chain 6. A mounting frame 2 is fixedly connected to the sprocket chain. The guide rods 10 on both sides of the frame 1 pass through both sides of the mounting frame 2, and the mounting frame 2 is slidably connected to the guide rods 10. The mounting frame 2 moves along the longitudinal direction of the frame 1.

[0021] See Figure 1 , Figure 2 , Figure 4 and Figure 5 The mounting frame 2 has two sliding blocks 3 slidably connected to its top. Each of the two sliding blocks 3 has a baffle 4 passing through it, and the baffle 4 is vertically slidably connected to the sliding block 3. A vertical lead screw 8 is rotatably connected to one side of the mounting frame 2, and a motor is fixedly connected to the end of the lead screw 8. The motor at the end of the lead screw 8 is fixedly connected to the mounting frame 2. A vertical guide rod 11 is fixedly connected to the other side of the mounting frame 2. The mounting frame also includes a movable frame 5. One side of the movable frame 5 is fixedly connected to the slider of the lead screw 8, and the guide rod 11 passes through the other side of the movable frame 5, slidably connected to the movable frame 5. A horizontal bidirectional lead screw 9 is rotatably connected to the top of the movable frame 5, and a motor is fixedly connected to the end of the bidirectional lead screw 9. The motor at the end of the bidirectional lead screw 9 is fixedly connected to the movable frame 5. The upper ends of the two baffles 4 pass through the top of the movable frame 5, and the two baffles 4 are fixedly connected to the two sliders of the bidirectional lead screw 9. A horizontal groove is provided where the baffle 4 passes through the movable frame 5, allowing the baffle 4 to slide along the groove.

[0022] Working Principle: The take-up area of ​​frame 1 is equipped with a lifting plate. Based on the length and width of the cut paper, motor 7 drives the sprocket and chain 6 to rotate. The chain pulls the mounting frame 2 along the two guide rods 10, moving it longitudinally relative to frame 1. Mounting frame 2 drives the lead screw 8 and the moving frame 5 to move. The moving frame 5 drives the upper bidirectional lead screw 9 and the two baffles 4 to move, moving the baffles 4 away from or closer to frame 1, adjusting the longitudinal distance between the baffles 4 and the tail end of frame 1. Then, the bidirectional lead screw 9 rotates, and its two sliders drive the two baffles 4 to move laterally towards each other relative to mounting frame 2 and moving frame 5, moving the two baffles 4 closer together or further apart, adjusting the distance between the two baffles 4 so that they are positioned between the two straight lines containing the left and right edges of the paper. Then, the lead screw 8 rotates, and its slider drives the moving frame 5 to descend along the guide rod 11. The moving frame 5 drives the two baffles 4 to descend, so that the bottom ends of the two baffles 4 abut against the surface of the lifting plate.

[0023] After the printed text and patterns on the paper are cut by the slitting device, the conveying mechanism on the frame 1 transports the paper onto the lifting plate. The paper continues to move on the lifting plate, stopping when it hits the baffle 4. The next cut paper continues to move onto the lifting plate, where it is stopped by the baffle 4 and falls on top of the previous paper. This process continues, with the paper stacking on the lifting plate to form a paper pile. When the paper pile reaches a certain height, the top paper exceeds the table surface of the slitting device. The lifting plate lowers the paper pile, and simultaneously, the lead screw 8 rotates its slider, which, through the moving frame 5, lowers the two baffles 4, ensuring that the bottom of the baffles 4 continues to press against the surface of the lifting plate, thus preventing each sheet of paper in the stack from moving. For every certain distance the paper pile rises, the lifting plate lowers the stack by a corresponding distance, and the baffles 4 also descend, blocking the back of each sheet in the stack and preventing movement due to external forces caused by the baffles 4 not being able to restrain it. Once the lifting plate has enough paper, it descends to its lowest position, the lead screw 8 rotates in the opposite direction, and its slider drives the baffle 4 to rise, so that the lowest part of the baffle 4 moves above the top of the paper stack, and then the paper can be removed from the lifting plate.
