AI Technical Summary
Existing cardboard edge-sealing mechanisms suffer from uneven bonding between the face paper and the cardboard side, leading to bulging. Furthermore, the edge-sealing of triangular cardboard is prone to wrinkling, affecting both aesthetics and quality.
The cardboard edge-wrapping mechanism includes a worktable, cardboard positioning components, and folding components. Through the coordinated movement of the side pressure plate and the folding plate, the face paper is made to adhere smoothly to the side of the cardboard, avoiding bulges. The folding plate pushes the face paper to fold along the upper surface of the cardboard to achieve edge wrapping.
This achieves a smooth fit between the face paper and the cardboard side, avoiding bulges and improving the aesthetics and quality of the edge binding, especially for triangular cardboard edges which are wrinkle-free.

Description
Technical Field
[0001] This utility model relates to the field of cover-making machines, specifically a cardboard edge-wrapping mechanism. Background Technology
[0002] Hardcover books and gift boxes have high requirements for appearance; the outer surface of the cardboard is covered with exquisite face paper, and the face paper must also bind the edges of the cardboard. Figure 1 This is a schematic diagram of cardboard edge binding. Existing cardboard edge binding has several problems: 1. The linerboard and the cardboard side are not evenly bonded, easily causing bulges, which not only affects aesthetics but also makes it prone to damage; 2. Wrinkles appear on the edges of triangular cardboard, affecting the quality of the edge binding. Utility Model Content
[0003] In view of the technical problems existing in the background art, the technical problem solved by this utility model is to provide a cardboard edge-wrapping mechanism that provides flat and aesthetically pleasing edges.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: the cardboard edge-wrapping mechanism is characterized by including a worktable, a cardboard positioning component, and an edge-folding component;
[0005] The cardboard positioning component moves up and down relative to the worktable;
[0006] The folding component is located on the side of the workbench, and includes a folding plate, a side pressure plate, and a base.
[0007] - The side pressure plate, which is opposite to the side of the cardboard, moves on the base relative to the side of the cardboard on the worktable.
[0008] -The folding plate is above the side pressure plate and higher than the cardboard, and the folding plate moves obliquely up and down on the base relative to the upper surface of the cardboard on the worktable;
[0009] During edge binding, the cardboard positioning piece moves down and presses down on the cardboard on the worktable. The face paper is blocked by the side pressure plate or the folding plate and curls up upward. The side pressure plate moves to the side of the cardboard so that the face paper is attached to the side of the cardboard. Then the folding plate moves diagonally downward and pushes the face paper to cover the upper surface of the cardboard.
[0010] In this invention, the folding plate is higher than the cardboard. When the cardboard is not pressed down, the bottom face paper extends beyond both sides of the cardboard. This portion of the face paper is used for edge binding. The face paper for edge binding on both sides is on the folding plate. The cardboard positioning component presses down on the cardboard to fix it on the worktable. The cardboard moves downward relative to the folding plate and the side pressure plate, causing the face paper for edge binding on both sides to curl upward along the bottom edge of the cardboard, preparing for edge binding. Subsequently, the side pressure plate moves to the side of the cardboard, causing the curled-up face paper to adhere to the side of the cardboard. The pressure of the side pressure plate makes the face paper adhere to the side plate and flat, avoiding bulges on the side of the cardboard. After the face paper is pressed sideways, it is roughly vertically upward. Then, the folding plate moves diagonally downward, pushing the face paper to fold along the top edge of the cardboard towards the upper surface of the cardboard. Under the pressure of the folding plate, the face paper adheres to the upper surface of the cardboard, achieving edge binding of the cardboard with the face paper. Moreover, the edge binding is flat and aesthetically pleasing. After the edge binding is completed, the side pressure plate retracts, and the folding plate retracts diagonally upward and is higher than the cardboard, making way for the cardboard conveying.
[0011] Preferably, the folding plate is connected to the piston rod of the first cylinder, and the base is provided with a first inclined seat. The first cylinder is mounted on the first inclined seat, and the piston rod of the first cylinder forms a first angle with the horizontal plane. The extension and retraction of the piston rod drives the folding plate to move obliquely, making the cylinder drive more flexible and facilitating the adjustment and use of the folding plate.
[0012] Preferably, the side pressure plate moves obliquely up and down relative to the side of the cardboard on the worktable on the base;
[0013] After the edge binding is completed, the side pressure plate moves diagonally downward and is lower than the cardboard to make room for the cardboard. In this way, the cardboard is between the side pressure plate and the folding plate, and the cardboard can be output from between the two.
[0014] Preferably, the side pressure plate is connected to the piston rod of the second cylinder, the base is provided with a second inclined seat, the second cylinder is mounted on the second inclined seat, and the piston rod of the second cylinder forms a second angle with the horizontal plane.
[0015] Preferably, the folded edge plate is disposed on the first inclined seat, the side pressure plate is disposed on the second inclined seat, and the first inclined seat is mounted on the second inclined seat;
[0016] The base is equipped with a longitudinally arranged guide, and a movable plate is slidably mounted on the guide. The second inclined seat is rotatably mounted on the movable plate. The folding component is adjusted by moving or rotating longitudinally according to the shape of the cardboard to meet the edge-wrapping requirements of the cardboard.
[0017] The base has two sets of first and second inclined seats and a movable plate. It is suitable for edge binding of triangular cardboard. The two sets of first and second inclined seats can be equipped with two folding plates and side pressure plates, so that the two sides of the triangular cardboard are bound by the two folding plates. This makes the edge binding smooth, avoids wrinkles, and improves the edge binding quality.
[0018] Preferably, the folded edge plate is connected to the piston rod of the first cylinder, and the first cylinder is mounted on the first inclined seat;
[0019] The side pressure plate is connected to the piston rod of the second cylinder, the second cylinder is mounted on the second inclined seat, and the first inclined seat is mounted on the second inclined seat;
[0020] The base is provided with a longitudinally arranged guide, the movable plate is slidably disposed on the guide, and the second inclined seat is rotatably mounted on the movable plate;
[0021] The base is provided with two sets of the first cylinder, the first inclined seat, the second cylinder, the second inclined seat, and the moving plate.
[0022] Preferably, the base is laterally slidable on the machine base. Lateral movement of the base moves the folding edge component away from the cardboard, making room for the cardboard.
[0023] Preferably, the cardboard edge-wrapping mechanism further includes a conveying component for feeding the cardboard onto the worktable. The conveying component includes a vertically lifting suction element and a driving element for longitudinal movement of the suction element. The cardboard is fed onto the worktable by the suction element.
[0024] Preferably, the workbench includes a conveyor belt and a pallet, the pallet being positioned to the side of the conveyor belt and closer to the side pressure plate, and the cardboard positioning element pressing against the pallet. The finished cardboard is then conveyed out by the conveyor belt.
[0025] The conveyor belt is equipped with a pusher plate. The conveyor belt is driven, and the pusher plate pushes the cardboard out.
[0026] Preferably, the pallet can be replaced and mounted on the machine base, and the side of the pallet matches the side of the cardboard. Attached Figure Description

[0032] The following describes the embodiments and related details and working principles of this utility model with reference to the accompanying drawings. The cardboard edge-wrapping mechanism is used to wrap the sides of the cardboard. At this time, the cardboard 1 and the face paper 2 are bonded together, with the face paper on the bottom and the cardboard on top, and the face paper is larger than the cardboard. The excess part of the face paper 2 is used for edge wrapping. Figure 1 In the middle, the left side of cardboard 1 is triangular, and the right side is straight; the cardboard is edged from the front and back sides, and the left and right sides are not edged until the left and right sides of the cardboard are edged.
[0033] This cardboard edge-wrapping mechanism includes a worktable 3, a cardboard positioning component, and an edge-folding component. The cardboard positioning component is positioned above the worktable 3 and moves up and down relative to the worktable 3. The edge-folding component is positioned to the side of the worktable 3 and includes an edge-folding plate 4, a side pressure plate 5, and a base. The side pressure plate 5 is opposite to the side of the cardboard, i.e., parallel to the side of the cardboard. The side pressure plate 5 moves relative to the side of the cardboard on the worktable 3 on the base, including horizontal movement and oblique vertical movement. The side pressure plate 5 presses against the side of the cardboard, making the face paper adhere to the side of the cardboard and preventing bulging. The edge-folding plate 4 is above the side pressure plate 5 and higher than the cardboard. The edge-folding plate 4 moves obliquely vertically relative to the upper surface of the cardboard on the worktable 3 on the base. During edge binding, the cardboard positioning piece moves down and presses down on the cardboard on the worktable 3. The face paper is blocked by the side pressure plate 5 or the folding plate 4 and curls upward. The side pressure plate 5 moves towards the side of the cardboard and presses against the side of the cardboard, so that the face paper is in contact with the side of the cardboard. The pressure of the side pressure plate 5 makes the face paper adhere to the side plate and flat, avoiding bulges on the side of the cardboard. After the face paper is pressed sideways, it is roughly vertically upward. Then, the folding plate 4 moves diagonally downward, pushing the face paper to fold along the top edge of the cardboard towards the upper surface of the cardboard. Under the pressure of the folding plate 4, the face paper adheres to the upper surface of the cardboard, realizing the edge binding of the cardboard with the face paper. After the edge binding is completed, the side pressure plate 5 retracts, and the folding plate 4 retracts diagonally upward and is higher than the cardboard, making way for the cardboard to be conveyed.
[0034] If the cardboard has an irregularly shaped side, such as a slanted or triangular side, the side pressure plate 5 must make way for the cardboard when it is horizontally fed out after the edge binding is completed. The base 62 is slidably mounted on the machine base 6. The machine base 6 is equipped with a linear guide rail 61, and the base 62 is slidably mounted on the linear guide rail 61. The lateral movement of the base increases the lateral movement stroke of the folding component, allowing it to move away from the cardboard after the edge binding is completed, thus making way for the cardboard. If the inclination angle of the cardboard side is small, the side pressure plate can also make way for the cardboard by moving obliquely. The side pressure plate 5 moves obliquely up and down relative to the side of the cardboard on the worktable 3 on the base. After the edge binding is completed, the side pressure plate 5 moves obliquely downward and is lower than the cardboard, thus making way for it. The cardboard is between the side pressure plate 5 and the folding plate 4 and can be output from between the two. In this case, the base does not need to move laterally to make way for the cardboard. If the oblique movement of the side pressure plate alone cannot meet the need for making way, then the base must move laterally to make way for the cardboard.
[0035] The movement of the folding plate and side pressure plate can be driven by a motor combined with a cam mechanism, or by a cylinder. See appendix. Figure 4 The folded edge plate 4 is connected to the piston rod of the first cylinder 41. The base is provided with a first inclined seat 42 and a second inclined seat 52. The first cylinder 41 is mounted on the first inclined seat 42. The first inclined seat 42 makes the piston rod of the first cylinder 41 obliquely downward relative to the horizontal plane, and the piston rod of the first cylinder 41 forms a first angle A with the horizontal plane. When the piston rod of the first cylinder 41 extends, the folded edge plate 4 moves obliquely downward, and when it retracts, it moves obliquely upward. The first inclined seat 42 is mounted on the second inclined seat, and the second cylinder 51 is mounted on the second inclined seat in the figure. The side pressure plate 5 is connected to the piston rod of the second cylinder 51. The second cylinder 51 is mounted on the second inclined seat 52. If the side pressure plate moves horizontally, the piston rod of the second cylinder is parallel to the horizontal plane. If the side pressure plate moves obliquely in the up-down direction, the second inclined seat 52 causes the piston rod of the second cylinder 51 to tilt upward relative to the horizontal plane. The piston rod of the second cylinder 51 forms a second included angle B with the horizontal plane. When the piston rod of the second cylinder 51 extends, the side pressure plate 5 moves obliquely upward. When it retracts, the side pressure plate 5 moves obliquely downward.
[0036] Since cardboard has different specifications and side shapes, in order to meet the edge-wrapping requirements of different cardboard, the base is provided with a longitudinally arranged guide 63. A movable plate 64 is slidably mounted on the guide 63. The second inclined seat 52 is rotatably mounted on the movable plate 64. The second inclined seat 52 rotates on the movable plate 64, which can adjust the horizontal angle of the side pressure plate 5 and the folding plate 4. The longitudinal movement of the movable plate 64 on the guide 63 adjusts the longitudinal position of the side pressure plate 5 and the folding plate 4 relative to the worktable 3.
[0037] To improve the edge-binding quality of irregularly shaped sides, the base is equipped with two sets of the first inclined seat 42, the second inclined seat 52, and the moving plate 64. Since the folding plate and the side pressure plate are driven by cylinders, two sets of the first cylinder 41 and the second cylinder 51 are also provided. For example, when binding the edges of triangular cardboard, the two sets of first cylinders 41 drive the two folding plates 4 respectively, so that the two sides of the triangular cardboard are bound by the two folding plates 4. This results in a smooth edge binding, avoids wrinkles, and improves the edge-binding quality. Figure 1 In the middle, the left side of the cardboard is a triangular side, and the right side is a flat side. The left-side folding component uses two sets of folding plates 4 and side pressure plates 5, respectively mounted on two first cylinders 41 and two second cylinders 51. By adjusting the angle of the second inclined seat 52 on the moving plate 64 and the longitudinal position of the moving plate 64 on the guide 63, the two folding plates 4 and side pressure plates 5 correspond to the two sides of the triangular side, allowing the two sets of folding plates 4 and side pressure plates 5 to move independently, improving the flatness of the edge. The right-side folding component uses one set of folding plates 4 and side pressure plates 5, i.e., two sets of cylinders are arranged longitudinally in a straight line. The folding plates 4 are mounted on two first cylinders 41, and the side pressure plates 5 are mounted on two second cylinders 51. Figure 2 As shown. Of course, one side can also use two sets of structures for the first cylinder 41, the first inclined seat 42, the second cylinder 51, the second inclined seat 52 and the moving plate 64, and the other side can use one set of structures.
[0038] The cardboard edge-wrapping mechanism also includes a conveying component that feeds the cardboard onto the worktable 3. The conveying component includes a vertically lifting suction element and a driving element that drives the suction element to move longitudinally. The cardboard is fed onto the worktable 3 by the suction element. The worktable 3 includes a tray 32, and the cardboard positioning element is pressed against the tray 32. The tray 32 can be interchangeably mounted on the machine base 6, and the side of the tray 32 matches the side of the cardboard. (See attached image) Figure 2 The left pallet 32 has a triangular side that matches the left side of the cardboard; the right pallet 32 has a straight side that matches the right side of the cardboard. The pallets 32 provide better support for the edge binding of the cardboard, improving the binding effect. To improve efficiency, the workbench 3 also includes a conveyor belt 31. The pallets 32 are positioned to the side of the conveyor belt 31 and closer to the side pressure plate 5. The bound cardboard is output by the conveyor belt. The conveyor belt can be a suction belt, which sucks up and transports the cardboard; or the conveyor belt can be equipped with a pusher plate, and the pusher plate on the conveyor belt drives the bound cardboard forward.
[0039] The following is in conjunction with the appendix Figure 1 and 2The working principle of the preferred embodiment is further explained as follows: The two folding plates 4 and the two pressure plates 5 on the left side of the folding component are respectively arranged parallel to the two sides of the left triangle of the cardboard. The right side folding component has only one folding plate 4 and one pressure plate 5, which are parallel to the straight right side of the cardboard. In the initial state, the cardboard positioning component moves upward away from the worktable 3. The suction component feeds the cardboard onto the worktable 3. At this time, the edge-wrapping parts of the face paper on both sides of the cardboard are covered on the folding plate 4. The cardboard positioning component moves downward to press down on the cardboard and fix it on the worktable 3. Because the folding plate 4 is higher than the cardboard, the cardboard moves downward relative to the folding plate 4, so that the edge-wrapping part of the face paper curls up along the bottom edge of the side of the cardboard, preparing for the edge wrapping. Then, the side pressure plate 5 moves to the side of the cardboard so that the curled face paper is attached to the side of the cardboard. The pressure of the side pressure plate 5 makes the face paper adhere to the side plate and flat, avoiding bulges on the side of the cardboard. After the face paper is pressed sideways, it is roughly vertically upward. Then, the folding plate 4 moves diagonally downward, pushing the face paper to fold along the top edge of the cardboard side towards the upper surface of the cardboard. Under the pressure of the folding plate 4, the face paper adheres to the upper surface of the cardboard, achieving edge wrapping of the cardboard. The left side of the cardboard is triangular, and there is an overlapping part for the edge wrapping of the face paper. Therefore, it is best for the two sets of folding plates 4 to fold the edge in a staggered manner. After the edge wrapping is completed, the side pressing plate 5 moves diagonally downward and is lower than the cardboard, while the folding plate 4 moves diagonally upward and is higher than the cardboard. Both make way for the conveying of the cardboard, and the conveyor belt 31 pneumatically outputs the edge-wrapped cardboard.
