Description

Technical Field

[0001] The present invention relates to the technical field of bookbinding machines, and particularly to an intelligent control device for the length of side glue cutting of a bookbinding machine. Background Art

[0002] A bookbinding machine is a device that binds sheets of paper into a book using hot melt adhesive, and is widely used in the production of books, periodicals, picture albums, etc. Traditional binding methods such as thread binding and saddle stitching have problems such as low binding strength, low efficiency, or poor aesthetics, and it has become difficult to meet the requirements of modern printing and binding for efficiency, quality, and aesthetics. With the development of hot melt adhesive technology, especially the wide application of EVA and PUR adhesives, the binding effect of bookbinding machines has been significantly improved. At the same time, the introduction of automation and intelligent control technology has enabled bookbinding machines to have functions such as automatic paper feeding, precise temperature control, and rapid binding, greatly improving production efficiency and binding quality, and becoming an important device for modern post-press processing.

[0003] During the bookbinding process, side glue and cut glue are carried out mainly to improve the firmness, readability, and aesthetics of book binding. During the bookbinding process, in order to make the hot melt adhesive penetrate more firmly between the sheets of paper and improve the binding strength, side glue is usually applied on both sides of the spine to increase the bonding area between the book block and the cover and prevent the pages from falling off. At the same time, too much or uncontrolled hot melt adhesive is likely to overflow to both sides of the book, affecting aesthetics and even causing difficulty in turning pages. Therefore, cut glue treatment is required to remove the excess glue material, making the edges of the book neat and beautiful and ensuring the quality of the finished product.

[0004] Existing side glue cutting devices of bookbinding machines are generally set to be adjustable in length to meet books of different sizes. However, adjustments need to be made before each use, which may cause some problems: in the use of small graphic studios, frequent adjustments are required, resulting in a long processing time and low processing efficiency; secondly, even for the same batch of books of the same size, there are still certain length deviations. Using a fixed cut glue distance may result in incomplete cut glue or even damage to the books.

[0005] In view of the above situation, in order to overcome the above technical problems, the present invention designs an intelligent control device for the length of side glue cutting of a bookbinding machine, which solves the above technical problems. Summary of the Invention

Specific Embodiments

[0022] To better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0023] As Figures 1-10 shown, an intelligent control device for the edge glue cutting length of a bookbinding machine provided by the present invention mainly includes: a bracket 1, a mounting component 2, a driving component 3, a cutting mechanism 4, and a fixing component 5. The bracket 1 is the basic structure of the device, fixedly installed on the ground, generally arranged on the adjacent side of the bookbinding part of the bookbinding machine. The main function of the bracket 1 is to provide stable support for the entire glue cutting and pressing mechanism, ensuring good stability and load-bearing capacity of the relevant structures during the working process. At the same time, the position setting of the bracket 1 facilitates the immediate entry into the glue cutting and solidifying operations after the book is bound, improving the overall production efficiency.

[0024] The mounting component 2 is installed on the upper part of the bracket 1 and is a key component connecting the other functional modules. A sliding groove 22 is provided on this component, which is used to restrict the internal moving member (such as the fixing component 5) to perform linear reciprocating motion along a preset trajectory. Through the structural design of the sliding groove 22, it can effectively prevent the moving parts from shifting or shaking, thereby improving the accuracy and reliability of the glue cutting operation. In addition, the mounting component 2 also serves as the mounting base for the driving component 3 and the cutting mechanism 4, providing mechanical guidance for their operation.

[0025] The driving component 3 is installed in the mounting component 2, and its function is to drive the cutting mechanism 4 to move along a set path and accurately position it at the edge area of the bound book. Driven by the driving component 3, the cutting mechanism 4 moves from both sides of the bound book towards the middle, and can be adaptively adjusted according to the actual width and length of the book, realizing the edge glue cutting operation for books of different specifications. This mechanism has good adjustment ability and can effectively avoid affecting the quality of the bound finished product due to excessive or insufficient glue cutting.

[0026] The fixing component 5 is arranged in the mounting component 2 and is driven by a telescopic cylinder 25, and is used to press and fix the side of the book before glue cutting. This step can not only play the role of solidifying and pressing the glue, promoting the uniform penetration of the hot melt glue and enhancing the adhesion, but also ensure that the book is in a stable state during the glue cutting process, effectively improving the accuracy and consistency of the glue cutting process, thereby ensuring the overall bookbinding quality. This device has a high degree of integration and strong intelligent control, and is suitable for the bookbinding processing of books of multiple specifications.

[0027] The installation component 2 includes key components such as an installation plate 21, a sliding groove 22, a limiting groove 23, an installation frame 24, and a telescopic cylinder 25. The installation plate 21, as the basic structure of the entire installation component 2, is firmly installed on the bracket 1 and serves as a carrier and support. The sliding groove 22 is opened on the central axis of the installation plate 21 and is symmetrically distributed to ensure that the sliding component moves smoothly in a straight line during operation. This sliding groove 22 is mainly used to guide the fixed component 5 to perform reciprocating motion along a set trajectory, preventing deviation during the motion process, thereby improving the operation accuracy and stability of the overall device.

[0028] As Figures 2-3 shown, a limiting groove 23 is further opened on the inner side of the sliding groove 22. The cross-section of the limiting groove 23 is trapezoidal in structure. This structural design facilitates closer cooperation with the corresponding guide components, effectively restricting the movement range of each moving part in the installation component 2 and avoiding unstable operation caused by poor sliding or excessive gaps. The installation frame 24 is installed below the installation plate 21 and serves as the fixed base of the telescopic cylinder 25, providing a stable installation position and support space. The telescopic cylinder 25 is installed inside the installation frame 24. The two telescopic cylinders 25 are arranged on both sides of the sliding groove 22 and can drive the two fixed components 5 respectively.

[0029] During the operation of the device, the telescopic speeds of the two telescopic cylinders 25 are kept consistent, enabling the two fixed components 5 to move towards the middle simultaneously and at the same speed, applying synchronous pressure fixation to both sides of the glued book. This synchronous action can not only effectively improve the uniformity of clamping but also ensure that the force on the spine glue layer during the gluing process is consistent, further enhancing the firmness and overall quality of the glued finished product.

[0030] As Figures 2-3 shown, the driving component 3 mainly includes a protective shell 31, a through hole 32, a guide post 33, and a driving motor 34, which is the core structure in the present invention to achieve precise telescoping and positioning of the cutting mechanism 4. The protective shell 31 is installed above the installation component 2 and serves as the external structural shell of the driving component 3. Its interior is hollow-designed to accommodate and protect the internal transmission and guiding elements, preventing dust, debris, or accidental impacts from damaging the internal mechanism and extending the service life of the device. A through hole 32 is provided on the inner side of the protective shell 31, which is connected to the cutting mechanism 4 and serves as the path channel for the forward and backward movement of the cutting mechanism 4.

[0031] The inner wall of the through hole 32 is provided with a spiral pattern, which is used to cooperate with the cutting mechanism 4 to realize the telescopic movement of the cutting mechanism 4 along the axial direction. The spiral structure is similar to a screw drive, which can convert the rotational movement into a linear movement, so that the cutting mechanism 4 can adaptively move to the middle or both sides according to the length of the book. Guide columns 33 are also provided on both sides of the through hole 32 to guide the movement of the cutting mechanism 4, limit its rotation tendency, ensure that the cutting mechanism 4 only performs linear telescopic movement, does not deviate or rotate, and improves the stability and accuracy of the glue cutting operation.

[0032] The drive motor 34 is installed on the side of the protective shell 31 and is the core power source for driving the entire cutting action. The drive motor 34 is connected to the drive worm 41 to drive it to rotate, thereby driving the cutting mechanism 4 to move in an efficient and controllable linear manner through the spiral transmission system to achieve accurate glue cutting. This structure has good mechanical stability and automatic adjustment capabilities, ensuring that accurate and fast edge glue cutting operations can be completed under different book size conditions.

[0033] like Figure 4 As shown, the cutting mechanism 4 is the key execution structure for realizing accurate cutting of the edge glue in the present invention, and its structural design is reasonable, the transmission is smooth, and the positioning is accurate, which ensures the efficient operation of the whole machine and the reliability of the glue binding quality. The cutting mechanism 4 mainly includes five main parts: a driving worm 41, a rotating assembly 42, a telescopic rod 43, a connecting bearing 44, and a cutting assembly 45.

[0034] The driving worm 41 is installed inside the driving assembly 3 and is one of the core components of power transmission. One end of the driving worm 41 is connected to the driving motor 34. When the motor is working, the driving worm 41 is driven to start rotating. The rotation of the driving worm 41 further drives the rotating assembly 42 installed thereon to move together. The rotating assembly 42 is arranged inside the protective shell 31, and is mainly used to transmit the rotational power of the worm to the telescopic rod 43, and convert the rotational action into linear displacement through structural conversion, thereby realizing the cutting action.

[0035] The telescopic rod 43 is installed on the side of the rotating assembly 42. Its main body is cylindrical, and its outer surface is precisely processed with a spiral groove, which precisely meshes with the spiral pattern in the hole 32 of the aforementioned driving assembly 3. Driven by the rotation of the rotating assembly 42, the telescopic rod 43 generates a stable and smooth axial telescopic movement through the "rotation-guide spiral groove" mechanism, realizing the precise advancement or retraction of the cutting mechanism 4 in the horizontal direction, which meets the requirements of cutting the edge glue of books of different widths.

[0036] A connecting bearing 44 is provided at one end of the telescopic rod 43. On the one hand, the connecting bearing 44 serves to connect the telescopic rod 43 and the cutting assembly 45. On the other hand, through its internal structure, a flexible rotational connection is maintained between the cutting assembly 45 and the telescopic rod 43. In this way, the cutting assembly 45 can always maintain a horizontal posture during the advancement of the telescopic rod 43, effectively fitting the two sides of the book, and avoiding the risk of uneven glue cutting or damaged book pages caused by cutting angle errors.

[0037] Finally, the cutting assembly 45 is installed outside the connecting bearing 44 and is the executing element that directly contacts the two sides of the glued book and performs the cutting and glue cutting tasks. Its blade or cutting part fits the edge of the book and performs a smooth cut when the telescopic action is completed, precisely removing the excess edge glue, improving the neatness and beauty of the book edge, and at the same time ensuring the consistency and quality of the glued finished product. The entire cutting mechanism 4 is closely coordinated and operates efficiently, and is particularly suitable for multi-specification and multi-batch graphic quick printing and glue binding production scenarios.

[0038] As Figure 6 shown, the rotating assembly 42 is the key mechanical structure for realizing the axial advancement and precise positioning of the cutting mechanism 4, mainly including components such as a driving worm gear 421, a mounting shaft 422, a rotating shaft 423, and a connecting convex block 424. They are closely coordinated and have a stable structure to ensure smoothness and efficiency during the operation of the whole machine. The driving worm gear 421 is installed below the driving worm 41 and realizes power transmission with the driving worm 41 in a standard worm and worm gear meshing manner. The driving motor 34 transmits power to the driving worm gear 421 through the rotation of the driving worm 41, thereby driving the entire rotating assembly 42 to rotate and work. This worm and worm gear structure has the advantages of good self-locking performance, smooth transmission, and large output torque, and is particularly suitable for precise telescopic or adjustment mechanisms.

[0039] The mounting shaft 422 is provided on one side of the driving worm gear 421, and one end is installed on the inner side surface of the protective shell 31 and is rotationally connected through a bearing or a rotating bracket 1. The mounting shaft 422 is mainly used to support the driving worm gear 421 and allow it to rotate freely on the shaft, ensuring uniform force on the worm gear and no eccentricity. On the other side of the driving worm gear 421, there is a rotating shaft 423 connected to it. The rotating shaft 423 is fixedly connected to the driving worm gear 421, that is, the two rotate synchronously. The rotating shaft 423 not only plays a role in transmitting power but also is the core component connecting the telescopic mechanism. At the top of the rotating shaft 423, there is a connecting convex block 424. The connecting convex block 424 has a circular structure and is used to achieve a snap-fit with the connecting chute 431 on the inner wall of the telescopic rod 43. This design ensures a firm rotational connection between the rotating shaft 423 and the telescopic rod 43, thereby driving the telescopic rod 43 to rotate synchronously.

[0040] The telescopic rod 43 is a hollow cylindrical structure, the interior of which is used to accommodate the rotating shaft 423, and the inner wall of which is provided with a connecting groove 431 that matches the connecting protrusion 424. The design of the groove can ensure that the connecting protrusion 424 is firmly engaged during rotation, while allowing the telescopic rod 43 to rotate along a set path driven by the connecting protrusion 424. When the rotating shaft 423 rotates, the connecting protrusion 424 is embedded in the groove to drive the telescopic rod 43 to rotate. Since the outer part of the telescopic rod 43 cooperates with the spiral pattern, its rotation will be converted into axial linear displacement, thereby driving the cutting assembly 45 to perform precise telescopic movement.

[0041] The design of the rotating assembly 42 cleverly converts rotational motion into linear motion, and improves the mechanical efficiency and transmission accuracy of the device through the hollow and slotted structure. It has a stable structure and strong adaptability, and is suitable for multiple specifications and multiple frequency glue cutting operations, with good practicality and reliability.

[0042] like Figure 7 As shown, the cutting assembly 45 is an important device for accurately cutting the excess glue layer at the edge of the glue-bound book in the present invention. It mainly includes a bonding block 451, a guide cylinder 452, a guide hole 453, a bonding slot 454 and a cutting knife 455. The coordinated work of these components ensures high-quality cutting and neat appearance of the glue-bound book.

[0043] The laminating block 451 is one of the core structures of the cutting assembly 45. It is installed outside the connecting bearing 44, and its side is tightly fitted with the side of the bound book. During the binding process, the laminating block 451 can stabilize the position of the book and ensure that the edge of the book is firmly fixed, providing accurate positioning support for the operation of the cutting knife 455. The design of the laminating block 451 can effectively prevent the book from shifting or shaking during the cutting process, thereby ensuring cutting accuracy.

[0044] The guide cylinder 452 is installed on the side of the bonding block 451 to guide and limit the bonding block 451. The guide cylinder 452 slides with the guide column 33 to fix the movement direction of the bonding block 451 and prevent it from rotating unnecessarily. The guide hole 453 is provided inside the guide sleeve to further enhance the stability and accuracy of the cutting assembly 45 and ensure that the bonding block 451 moves smoothly along the predetermined trajectory.

[0045] A bonding slot 454 is provided on the side of the bonding block 451, and a cutting knife 455 is arranged in the slot. The cutting edge of the cutting knife 455 faces the edge of the glue-bound book, and can accurately cut the excess solid glue layer and remove the excess glue portion at the edge of the book. Through this cutting process, the appearance of the glue-bound book can be ensured to be neat and tidy without excess glue layer, thereby improving the overall quality and durability of the book.

[0046] like Figure 8As shown, the fixing component 5 is a key component in the present invention for applying pressure and maintaining pressure on the glued book, ensuring that the book does not displace or deform during the gluing process, thereby improving the gluing quality. The fixing component 5 is composed of a telescopic block 51, a mounting block 52, a limiting block 53, a mounting sleeve 54, a contact component 55, an extrusion block 56, etc. Each component works together to provide stable support and pressure application functions.

[0047] The telescopic block 51 is installed below the mounting component 2, and its side is fixedly connected to the telescopic cylinder 25 through a connecting piece. Driven by the telescopic cylinder 25, the telescopic block 51 can move up and down to achieve precise pressure application actions. The movement of the telescopic block 51 is the core of the entire fixing component 5, which provides the necessary power support for subsequent pressure application actions.

[0048] The mounting block 52 is installed on top of the telescopic block 51, and its main function is to provide fixed support and carry the limiting block 53 and the mounting sleeve 54. The limiting block 53 is located on the side of the mounting block 52, and its cross-sectional shape is designed as a trapezoid for cooperation with the limiting groove 23. The function of the limiting groove 23 is to ensure that the limiting block 53 does not shift or fail during movement, thereby ensuring the stability and accuracy of the fixing component 5.

[0049] The mounting sleeve 54 is installed on the side of the mounting block 52, and the contact component 55 is installed inside it. The contact component 55 is connected to the extrusion block 56 through the mounting sleeve 54. The extrusion block 56 is installed below the mounting sleeve 54 and directly applies pressure to the glued book. Through the coordinated work of this series of components, the fixing component 5 can effectively apply pressure during the gluing process, ensure the neat edges of the book, firm gluing, and avoid deformation or loosening of the book caused by uneven pressure after gluing.

[0050] As Figure 9 shown, the design of the mounting sleeve 54 plays a crucial role in the bookbinding machine of the present invention. It is not only the support structure of the entire fixing component 5 but also has the function of precisely controlling the movement of the contact component 55. A telescopic chute 541 is opened inside the mounting sleeve 54. The main function of the telescopic chute 541 is to accommodate the limiting convex block 552 and limit the telescopic range of the contact component 55. In this way, the contact component 55 can perform precise telescopic movements during the gluing process, thereby realizing key operations such as pressure application and positioning of the glued book. The length of the telescopic chute 541 is designed to be three-quarters of the length of the mounting sleeve 54 to ensure that the contact component 55 has sufficient movement space to adapt to books of different thicknesses and sizes. However, the telescopic chute 541 is not provided at the very front end of the mounting sleeve 54. Such a design can effectively prevent the telescopic column 551 from falling off during operation, ensuring the stability and safety of the equipment operation.

[0051] To better support the movement of the contact component 55, a support spring 542 is also installed inside the mounting sleeve 54. The support spring 542 can provide additional support force during the movement, maintain the stability of the contact component 55, and prevent the contact frame 553 from losing its precise positioning due to vibrations or external forces generated during the movement. The function of the spring can not only relieve the impact burden of the device but also ensure that the contact component 55 remains stable during movement, thereby ensuring that both sides of the glued book are evenly pressurized without loosening or uneven pressurization.

[0052] As Figure 10 shown, the contact component 55 is an important execution unit in the fixed component 5. It consists of four parts: a telescopic column 551, a limit bump 552, a contact frame 553, and a contact pulley 554. The telescopic column 551 is installed inside the mounting sleeve 54 and cooperates with the limit bump 552 through the telescopic chute 541 to achieve precise telescopic movement. A limit bump 552 is installed outside the telescopic column 551. The main function of the limit bump 552 is to cooperate with the telescopic chute 541 so that the telescopic column 551 does not deviate from the predetermined trajectory during movement, thus ensuring the stable operation of the contact component 55.

[0053] The contact frame 553 is installed on the side of the telescopic column 551. The function of the contact frame 553 is to provide a fixed support for the contact pulley 554 and at the same time enable the contact pulley 554 to slide freely along the predetermined trajectory. The contact pulley 554 is installed inside the contact frame 553 and is the key execution part of the contact component 55. The main function of the contact pulley 554 is to come into contact with the side of the glued book first and perform preliminary positioning on it. Through the contact between the pulley and the glued book, the contact component 55 can ensure the accurate positioning of the book edge, providing a stable foundation for subsequent extrusion and reinforcement operations. The design of the contact pulley 554 ensures that the glued book will not have wrinkles or irregular deformations during extrusion and reinforcement, ensuring the neat and standard appearance of the book.

[0054] The extrusion block 56 can evenly pressurize both sides of the glued book through the precise control of the contact component 55. This can not only maintain the stable shape of the book but also effectively enhance the adhesion of the glue, improving the durability and service life of the glued book. The various components of the contact component 55 cooperate with each other in a coordinated and precise manner, ensuring the quality of the glued book and thus improving the efficiency and accuracy of the entire gluing process.

[0055] During the working process of the present invention, the glued book is placed on the upper surface of the mounting plate 21 by a manipulator after being glued. The telescopic cylinder 25 is activated to drive the fixing assembly 5 to fit and press on both sides of the glued book. The contact pulley 554 will first contact the side surface of the glued book and apply an initial pressure to it, thereby reducing the possibility of creases appearing on the glued book. Then, the extrusion block 56 contacts the glued book and extrudes it, thereby ensuring the quality of gluing and squeezing the excess glue to the side part of the glued book; Then, the drive motor 34 is activated. By driving the drive worm 41 to rotate, the drive worm wheel 421 is driven to rotate. Under the restriction of the mounting shaft 422, the drive worm wheel 421 always drives the rotating shaft. Through the clamping action of the connecting convex block 424 and the connecting chute 431, the telescopic rod 43 also rotates accordingly. Threaded patterns and threaded grooves are respectively provided on the surfaces of the telescopic rod 43 and the through hole 32 in contact therewith. Therefore, the telescopic rod 43 will move outwards when rotating; Due to the existence of the connecting bearing 44, the cutting assembly 45 will not rotate with the telescopic rod 43, but will move outwards. And the guiding cylinder 452 is on the guiding column 33, so that the cutting assembly 45 maintains a horizontal state during the movement until the fitting block 451 fits the side surface of the glued book. At this time, the drive worm 41 cannot continue to rotate, and due to the self-locking property of the worm and worm wheel, the cutting assembly 45 and the glued book can be kept in a tightly fitting state. After the sensor inside the drive motor 34 detects that it cannot continue to rotate, the power supply of the drive motor 34 is stopped, and a signal is sent to make the cutting knife 455 cut downwards to complete the operation of cutting off the glue.
