Description

Technical Field

[0001] This utility model relates to the field of perfect binding after printing, and in particular to a flipping mechanism for horizontal format books used in perfect binding. Background Technology

[0002] Books are important information carriers in daily life, and their production process typically includes printing, cutting, and binding. Perfect binding is a common binding method, using glue to bond pages to the spine, thus securing and shaping the book. However, in actual production, landscape-format books (i.e., books with the long side as the binding edge) require flipping during the binding process because their binding direction is inconsistent with the paper feed direction of the perfect binding equipment. Failure to flip the book can lead to weak binding or uneven glue distribution, thus affecting the book's quality.

[0003] Existing perfect binding flipping mechanisms are primarily designed for portrait-format books, typically employing mechanical clamping or a conveyor belt with rollers to achieve the flipping. These devices are simple in structure and stable in operation, making them widely used in perfect binding production lines for standard portrait-format books. However, their flipping mechanisms are usually fixed to the specifications and shape of portrait-format books, often failing to provide sufficient flexibility for flipping landscape-format books, thus limiting their practical application. Therefore, this paper proposes a landscape-format flipping mechanism for perfect binding to address these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a horizontal book flipping mechanism for perfect binding, aiming to improve the problem that the existing technology, which is fixed to adapt to the specifications and shape of vertical books, has a limited scope of application for flipping horizontal books.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figs. 1-3This utility model provides an embodiment of a book-folding mechanism for perfect binding, comprising a base plate 1. A climbing spring 8 is fixedly connected to the top of the base plate 1. The climbing spring 8 has a certain inclination angle, and its top end supports the book block 7 during the folding process, effectively guiding the book block 7 to gradually rise and providing a stable fulcrum for its folding, ensuring a smooth folding process. A lower side plate 2 is fixedly connected to the top of the base plate 1. Each side of the lower side plate 2 has a pre-drilled winding rod hole 9. The winding rod position can be adjusted according to different specifications of book blocks 7 through the pre-drilled winding rod holes 9, enhancing the adaptability of the device. A winding rod 10 is arranged between the lower side plates 2. The winding rod 10 cooperates with the climbing spring 8 to form a folding fulcrum, allowing the book block 7 to complete the folding action under the pushing action of the push rod 4, effectively realizing the gradual adjustment of the posture of the book block 7. A flipping funnel 11 is fixedly connected inside the base plate 1. The flipping funnel 11 is used to assist the flipping process of larger book blocks 7, providing an additional support surface to ensure the stability of the book block 7 during flipping, preventing misalignment or displacement, and further improving the reliability and efficiency of the equipment when handling book blocks 7 of different sizes. A second winding rod 12 is set between the lower side plates 2. The second winding rod 12 serves as another key fulcrum for the flipping of the book block 7, ensuring that the book block 7 can smoothly complete a 90-degree flip during the center of gravity shift. A push rod 4 is set at the top of the lower side plate 2. A support block 5 is fixedly connected to the side wall of the push rod 4. A chain 6 is connected to the side wall of the support block 5. The chain 6 drives the push rod 4 to move in a straight line. The push rod 4 plays a power transmission role in pushing the book block 7 to slide, climb, and flip along the base plate 1 in sequence, ensuring that the flipping action of the entire mechanism is smooth and efficient. A aligning lever 13 is set at the top of the base plate 1. The aligning lever 13 is located at the end of the movement path of the book block 7, which can neatly position the book block 7 after it has been flipped. A stop 15 is provided on the side wall of the alignment lever 13. The stop 15 is fixedly connected to the spring 14. The spring 14 enables the alignment lever 13 to automatically reset after the book block 7 is neatly arranged, ensuring the accurate position of the book block 7 after flipping, preparing for subsequent processes and improving the overall processing quality. An upper side plate 3 is provided on the top of the base plate 1. The book block 7 is placed between the upper side plate 3 and the lower side plate 2. The upper side plate 3 and the lower side plate 2 are used to limit the lateral displacement of the book block 7 during the flipping process, effectively preventing the book block 7 from shifting during sliding and flipping, ensuring that the book block 7 flips and slides along the predetermined path, further improving the stability and flipping accuracy of the equipment. Through the cooperation of the above structures, the flipping mechanism can achieve a 90-degree flipping of the book block 7 without affecting the function of the existing perfect binding line. It has a simple structure, strong adaptability, significantly improves the production efficiency of horizontal perfect binding and reduces production costs.

[0028] Working principle: The long side of the book block 7 first contacts the base plate 1, and slides along the base plate 1 for the first time under the push of the push rod 4. The push rod 4 moves in a straight line driven by the chain 6, pushing the book block 7 to the position of the climbing spring 8. During the climbing process, the front end of the book block 7 gradually rises along the climbing spring 8 fixed on the base plate 1, and the center of gravity shifts. When the book block 7 climbs to the top of the climbing spring 8, it uses the top of the climbing spring 8 as a fulcrum and, under the pushing force of the push rod 4, performs the first flip around the top of the climbing spring 8, causing its front end to tilt downwards and its lower left corner to approach the push rod 4. After completing the first flip, the book block 7 continues to slide forward and performs the second slide using the fulcrum of the winding rod 10 and the top of the climbing spring 8. When the book block 7 moves to the position of the winding rod 10, it performs the second flip around the winding rod 10 under the pushing force, using the winding rod 10 as a fulcrum. At this time, the center of gravity of the book block 7 is further adjusted, and the push rod 4 begins to contact the bottom of the book block 7. Subsequently, under the push of the push rod 4, the book block 7 slides for the third time along the support path between the first winding rod 10 and the base plate 1. When the front end of the book block 7 contacts the second winding rod 12, the second winding rod 12 completes the third flip, causing the book block 7 to rotate 90 degrees, changing from contacting the base plate 1 with its long side to contacting the base plate 1 with its short side, thus completing the flipping action. After the flipping is completed, the book block 7 continues to slide for the fourth time under the push of the push rod 4, entering the next station. At this time, the alignment lever 13 set at the end of the flipping mechanism uses the elastic force of the spring 14 to neatly arrange the book blocks 7, ensuring that the posture of the book block 7 is stable and parallel to the conveying path. For larger book blocks 7, during the flipping process, the flipping funnel 11 set on the base plate 1 provides auxiliary support to prevent the book block 7 from shifting or slipping during the flipping process, further improving the stability and applicability of the flipping.
