Description

Technical Field

[0001] This utility model relates to the field of book cover packaging production technology, and in particular to a book cover folding flap device. Background Technology

[0002] A book cover folding flap device is a piece of equipment used in the book manufacturing process. Its main function is to perform specific folding on the book cover to form the flap. This device can precisely control parameters such as the size and angle of the fold, ensuring that the shape and size of the flap meet the requirements of the book design.

[0003] Traditional book cover folding flap devices typically use two cylinders to drive two folding plates. While this can achieve book cover folding, it has the following problems in practical applications: it is difficult to ensure that the movement of the two folding plates is synchronized, and asynchrony will lead to uneven folding of the book cover, affecting the folding quality. Furthermore, the use of two cylinders increases subsequent maintenance costs. Therefore, we propose a book cover folding flap device. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a book cover folding flap device.

[0005] This utility model is achieved by the following technical solution: a book cover folding flap device, including a first frame, a first conveyor belt is provided inside the first frame, a support frame is fixedly connected to the top of the first frame, a first baffle and a second baffle are fixedly connected to the bottom of the support frame, and a folding component is provided at the right end of the support frame;

[0006] The folding assembly includes an extension plate, a first cylinder is fixedly connected to the top of the extension plate, the output end of the first cylinder passes through the extension plate and is fixedly connected to a connecting plate, a connecting rod is hinged to the bottom of the connecting plate, a fixing rod is fixedly connected to the end of the connecting rod away from the connecting plate, a mounting seat is rotatably connected to the surface of the fixing rod, and a folding plate is fixedly connected to the surface of the fixing rod.

[0007] The above technical solution uses two first baffles to limit the book's position, and four second baffles arranged in pairs to limit the pages that need to be folded on both sides of the book. The connecting rod consists of two hinged rods that can rotate. The output of the first cylinder pushes the connecting plate downwards, causing one rod to rotate around its hinge point with the connecting plate. This causes the other rod to expand outwards, rotating the fixed rod and causing the two folding plates to rotate inwards, thus folding the protruding pages of the book into flaps. Since only one first cylinder drives the two folding plates to fold the pages, the folding is synchronized, avoiding uneven folding caused by asynchrony and reducing subsequent maintenance costs.

[0008] As a further improvement to the above solution, the left end of the extension plate is fixedly connected to the right end of the support frame, and the bottom of the mounting base is fixedly connected to the top of the first frame.

[0009] The above technical solution uses the mounting base to support and limit the fixed rod, ensuring stability during rotation.

[0010] As a further improvement to the above solution, the number of each of the connecting rod, fixing rod, mounting base and folding plate is set to two.

[0011] As a further improvement to the above solution, a second frame is fixedly connected to the right end of the first frame, and a second conveyor belt is provided inside the second frame.

[0012] The above technical solution uses a second conveyor belt to transport the folded books to subsequent processes.

[0013] As a further improvement to the above solution, a mounting plate is fixedly connected to the top of the second frame, a second cylinder is fixedly connected to one end of the mounting plate, and a push plate is fixedly connected to the output end of the second cylinder.

[0014] The above technical solution involves using a second cylinder to move a pusher plate, which then pushes the book down so that it lies flat on the second conveyor belt, making it easier to flatten the book later.

[0015] As a further improvement to the above solution, a mounting bracket is fixedly connected to the top of the second frame, and a third cylinder is fixedly connected to the top of the mounting bracket.

[0016] The above technical solution uses a mounting bracket to install and fix the third cylinder, ensuring stability during use.

[0017] As a further improvement to the above solution, the output end of the third cylinder passes through the mounting bracket and is fixedly connected to a pressure plate, and the second frame is located at the rear end of the mounting plate.

[0018] The above technical solution uses the output of the third cylinder to push the pressure plate downward, pressing the book tightly and ensuring that the folded flaps are flat.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This invention features a folding assembly. Specifically, the output end of the first cylinder pushes the connecting plate downward, causing the connecting rod to rotate around the hinge point. Simultaneously, the fixed rod rotates, causing the two folding plates to rotate inward. This folds the protruding pages of the book into flaps. Since only one first cylinder drives the two folding plates to fold the pages, the folding is synchronized, avoiding uneven folding caused by asynchrony and reducing subsequent maintenance costs.

[0021] This utility model is designed with a first cylinder, a push plate, a third cylinder, and a pressure plate. Specifically, the push plate is moved by the second cylinder, which pushes the book down so that it lies flat on the second conveyor belt. When the flat book is conveyed to the mounting frame, the pressure plate is moved downward by the output of the third cylinder, which presses the book down to ensure that the folded pages are flat.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example

[0030] Please combine Figure 1-5 A book cover folding flap device according to this embodiment includes a first frame 1, a first conveyor belt 2 is provided inside the first frame 1, a support frame 3 is fixedly connected to the top of the first frame 1, a first baffle 4 and a second baffle 5 are fixedly connected to the bottom of the support frame 3, and a folding component 6 is provided at the right end of the support frame 3.

[0031] The folding assembly 6 includes an extension plate 601. A first cylinder 602 is fixedly connected to the top of the extension plate 601. The output end of the first cylinder 602 passes through the extension plate 601 and is fixedly connected to a connecting plate 603. A connecting rod 604 is hinged to the bottom of the connecting plate 603. A fixing rod 605 is fixedly connected to the end of the connecting rod 604 away from the connecting plate 603. A mounting base 606 is rotatably connected to the surface of the fixing rod 605. A folding plate 607 is fixedly connected to the surface of the fixing rod 605. The book is conveyed to the folding assembly 607 by the first conveyor belt 2. At the position of component 6, the first cylinder 602 is activated. The output end of the first cylinder 602 pushes the connecting plate 603 downward, causing the connecting rod 604 to rotate around the hinge point. At the same time, it drives the fixed rod 605 to rotate, causing the two folding plates 607 to rotate inward, thereby folding the protruding pages of the book into flaps. Since only one first cylinder 602 drives the two folding plates 607 to fold the pages, the folding is synchronized, avoiding uneven folding caused by asynchrony, and reducing subsequent maintenance costs.

[0032] The left end of the extension plate 601 is fixedly connected to the right end of the support frame 3, and the bottom of the mounting base 606 is fixedly connected to the top of the first frame 1.

[0033] There are two of each of the following components: connecting rod 604, fixing rod 605, mounting base 606, and folding plate 607.

[0034] The right end of the first frame 1 is fixedly connected to the second frame 7, and the second frame 7 is equipped with a second conveyor belt 8.

[0035] A mounting plate 9 is fixedly connected to the top of the second frame 7. A second cylinder 10 is fixedly connected to one end of the mounting plate 9. A push plate 11 is fixedly connected to the output end of the second cylinder 10. The push plate 11 is moved by the second cylinder 10, and the book is pushed down by the push plate 11 so that it lies flat on the second conveyor belt 8.

[0036] The top of the second frame 7 is fixedly connected to a mounting bracket 12, and the top of the mounting bracket 12 is fixedly connected to a third cylinder 13.

[0037] The output end of the third cylinder 13 passes through the mounting frame 12 and is fixedly connected to the pressure plate 14. The second frame 7 is located at the rear end of the mounting plate 9. When the flat book is transported to the position of the mounting frame 12, the pressure plate 14 is pushed downward by the output of the third cylinder 13, and the book is pressed tightly by the pressure plate 14 to ensure that the folded flaps are flat.

[0038] The implementation principle of the book cover folding flap device in this application embodiment is as follows: During use, the book is placed between two first baffles 4, and the pages to be folded are placed inside the second baffle 5. The book is transported to the folding assembly 6 by the first conveyor belt 2. The first cylinder 602 is activated, and its output pushes the connecting plate 603 downwards, causing the connecting rod 604 to rotate around the hinge point. Simultaneously, this causes the fixed rod 605 to rotate, causing the two folding plates 607 to rotate inwards, thereby folding the protruding pages of the book into flaps. This is achieved using only one first cylinder. The 602 drives two folding plates 607 to fold the pages, ensuring folding synchronization and avoiding uneven folding caused by asynchrony. This also reduces subsequent maintenance costs. After folding, the book is transported to the second conveyor belt 8 via the first conveyor belt 2. The second cylinder 10 pushes the push plate 11 to move, pushing the book down so that it lies flat on the second conveyor belt 8. When the flat book is transported to the mounting frame 12, the output of the third cylinder 13 pushes the pressure plate 14 downward, pressing the book firmly to ensure that the folded edges are flat.

[0039] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
