Description

Technical Field

[0001] This invention relates to the field of bookbinding technology, and in particular to a perforation device for traditional thread binding of irregularly shaped books using a special process. Background Technology

[0002] In today's rapidly developing cultural and creative industries, books are no longer limited to the traditional rectangular shape. Irregularly shaped books, with their unique visual effects and personalized designs, are widely used in gift books, cultural and creative products, and customized books, becoming an important development direction for the bookbinding industry. These irregularly shaped books often require the use of traditional thread binding techniques to enhance their artistic and collectible value. The precision of the spine perforation, a core aspect of traditional thread binding, directly determines the threading effect, binding sturdiness, and overall aesthetics, making it a key technical challenge in the production of irregularly shaped books.

[0003] In the current bookbinding field, traditional hole-punching technology is mainly designed for books with regular shapes, using hollow drill bits or ordinary bench drills with simple positioning tools. This can no longer meet the special processing needs of irregularly shaped books.

[0004] On the one hand, irregular spines of irregularly shaped books lack a unified positioning benchmark, and traditional processes lack suitable fixing structures, making it difficult to achieve precise alignment between the book's outline and the processing benchmark. This leads to book displacement and tilting during the punching process, making it impossible to accurately position multiple holes, ultimately resulting in hole offsets and uneven arrangement. This seriously affects the smooth progress of subsequent threading processes and may even lead to the scrapping of the book. On the other hand, different irregularly shaped books have significant differences in shape and thickness. Traditional fixing methods lack universality and cannot achieve stable clamping of diverse irregular structures. Moreover, the manual positioning and adjustment process is cumbersome, resulting not only in long processing cycles and low production efficiency for individual books, but also in inconsistent hole position accuracy and large differences in spine shape due to the randomness of manual operation, making it difficult to guarantee product consistency and pass rate. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and propose a punching device for special processes of irregularly shaped books, which includes a base, a puncher on the top of the base, a mounting seat detachably connected to the top of the base, and a mold assembly on the top of the mounting seat.

[0006] The top of the mounting base is provided with a fixed edge assembly, the bottom of the mounting base is provided with a drive assembly, and the bottom of the mounting base is provided with a feeding assembly.

[0007] The mounting base is equipped with a clamping component via a drive assembly, and a placement plate is rotatably connected to the mounting base.

[0008] The mold assembly includes a limiting plate, the bottom end of which is fixedly connected to the top of the mounting base. A sliding sleeve is slidably connected to the outer wall of the limiting plate, and a bolt is movably connected to the sliding sleeve. One end of the bolt is threadedly connected to a hole provided on the outer wall of the limiting plate. A mounting bracket is detachably connected to the outer wall of the sliding sleeve, and a template is rotatably connected to the outer wall of the mounting bracket.

[0009] Preferably, a limiting block is fixedly connected to the outer wall of the sliding sleeve, one end of the limiting block is in contact with the outer wall of the template, and a support rod is fixedly connected to the bottom outer wall of the template. By setting the limiting block and the support rod, the template can be limited and flipped. When the template is in use, the cooperation of the support rod, the placement plate and the limiting block will limit the template, so that the template can limit the spine of the book. After the book is punched, the placement plate no longer supports the support rod after flipping, and the template will rotate at this time, so as to facilitate the release of the spine of the book.

[0010] Preferably, the edge-fixing assembly includes a first threaded rod, the outer wall of which is threadedly connected to an ear plate provided on the top of the mounting base. One end of the first threaded rod is rotatably connected to a first edge-fixing plate. A limit rod is fixedly connected to the outer wall of the first edge-fixing plate. The outer wall of the limit rod is slidably connected to the ear plate provided on the top of the mounting base. A second edge-fixing plate is fixedly connected to the top of the mounting base. By setting the edge-fixing assembly, the edge of the book is positioned, thereby providing a clear side positioning reference for the book, avoiding left and right offset of the book during the punching process, and ensuring that the spine shape and hole position are consistent with the design standards.

[0011] Preferably, the clamping assembly includes a movable plate, on which a second threaded rod is threadedly connected. A pressing plate is rotatably connected to the bottom of the second threaded rod, and a soft pad is provided at the bottom of the pressing plate. By setting the clamping assembly, the book can be fixed. Fixing the book can secure the entire book to the mounting base, which can offset the impact and vibration when drilling, and prevent the book from splitting, curling the edges, or shifting the hole position.

[0012] Preferably, the drive assembly includes a motor, the bottom of the mounting base is detachably connected to the top of the motor, a driving bevel gear is fixedly connected to the motor shaft, a third threaded rod is rotatably connected to the mounting base, a driven bevel gear is fixedly connected to the bottom of the third threaded rod, the driven bevel gear meshes with the driving bevel gear, the outer wall of the third threaded rod is threadedly connected to a hole provided on the movable plate, a first gear is fixedly connected to the outer wall of the motor shaft, a second gear is rotatably connected to the bottom of the mounting base, the second gear meshes with the first gear, and the inner wall of the second gear... The mounting base has a slot, and a disc is rotatably connected to its bottom. A first spring telescopic rod is fixedly connected to the disc, and a locking block is fixedly connected to the telescopic end of the first spring telescopic rod. A reciprocating screw is fixedly connected to the outer wall of the disc. By setting a drive component, the clamping component and the unloading component can be linked together to connect the clamping and unloading processes. This allows the unlocking action to be automatically triggered after the book processing is completed, and the book to be unloaded and removed from the mold simultaneously. The release of the book after clamping and the unloading are connected, which can shorten the processing cycle of a single book, greatly increase the output per unit time, and thus improve production efficiency.

[0013] Preferably, a second spring telescopic rod is fixedly connected to the bottom of the mounting base, and a ball is fixedly connected to the telescopic end of the second spring telescopic rod. The ball at the telescopic end of the second spring telescopic rod fits into the groove on the disc. By setting the second spring telescopic rod, the disc is stabilized, avoiding unnecessary rotation of the disc during use, thereby preventing the rotation of the disc from driving the reciprocating screw and thus avoiding affecting the stability of the placement plate.

[0014] Preferably, a guide rod is fixedly connected to the top of the mounting base. The outer wall of the guide rod fits into the hole provided on the moving plate and the hole provided on the pressing plate. By setting the guide rod, the moving plate and the pressing plate are stabilized, thereby preventing the moving plate and the pressing plate from shaking when moving, and thus avoiding affecting the clamping of the books by the pressing plate.

[0015] Preferably, the unloading assembly includes a guide plate, the top of which is fixedly connected to the bottom of the mounting base. The guide plate is provided with a moving rod via a groove. The outer wall of the reciprocating screw is threadedly connected to a moving frame. A groove on the moving frame is slidably connected to one end of the moving rod. By setting the unloading assembly, the books are unloaded, thereby automatically removing the processed books from the mold, significantly shortening the processing cycle of a single product, and thus improving processing efficiency and continuity.

[0016] In summary, the present invention provides a perforation device for special processes of irregularly shaped books using traditional thread binding, which has the following beneficial effects:

[0017] 1. By setting up mold components, books of different shapes and thicknesses can be fixed. The mold components can make the outline of the book fit the mold structure perfectly, providing a clear benchmark for subsequent cutting and punching, thereby matching the positioning and processing requirements of irregular spines. At the same time, it can ensure the precise and uniformity of the punched holes, thereby ensuring product consistency and pass rate, and improving processing efficiency and shortening the cycle of a single book.

[0018] 2. By setting the edge-fixing component, the book edge is positioned, providing a clear side positioning reference for the book and preventing the book from shifting left or right during the drilling process. This ensures that the spine shape and hole positions are consistent with the design standards. At the same time, it can prevent the book from shifting due to vibration or force during drilling, ensuring uniform hole spacing and vertical hole positions, and avoiding problems such as uneven hole positions and tilted hole positions that make threading difficult.

[0019] 3. By setting up clamping components, the books are fixed in place. The books can be fixed as a whole to the base, which can offset the impact and vibration of drilling, prevent the books from splitting, curling the edges, or the holes from shifting. At the same time, it can prevent the two from sliding relative to each other during the cutting process, ensure that the curvature of the paper mold is accurately transmitted to the books, and prevent the books from deviating from their initial position due to external forces during the drilling process, ensuring that the hole positions and spine shapes of each book are completely consistent with the design standards.

[0020] 4. By setting up a feeding component, books can be fed into the mold automatically, which greatly shortens the processing cycle of a single product, thereby improving processing efficiency and continuity. At the same time, the feeding direction and landing point of the books can be precisely controlled, so that the books can automatically enter the subsequent processes, avoiding process interruptions or positional deviations caused by manual handling, and meeting the needs of large-scale and assembly line production of irregularly shaped books.

The mounting bracket 404 can connect the template 405 to the sliding sleeve 402, thereby fixing the spine of the book through the template 405.

[0041] like Figure 3 As shown, a limiting block 406 is fixedly connected to the outer wall of the sliding sleeve 402. One end of the limiting block 406 is in contact with the outer wall of the template 405. The limiting block 406 can limit the template 405. A support rod 407 is fixedly connected to the bottom outer wall of the template 405. The support rod 407 can limit the template 405 to prevent unnecessary flipping of the template 405.

[0042] like Figure 4As shown, the edge-fixing assembly 5 includes a first threaded rod 501. The outer wall of the first threaded rod 501 is threadedly connected to the ear plate provided on the top of the mounting base 3. The first threaded rod 501 can move left and right through the threaded connection. One end of the first threaded rod 501 is rotatably connected to a first edge-fixing plate 502. The movement of the first threaded rod 501 can drive the first edge-fixing plate 502 to move. The outer wall of the first edge-fixing plate 502 is fixedly connected to a limit rod 504. The outer wall of the limit rod 504 is slidably connected to the ear plate provided on the top of the mounting base 3. The limit rod 504 can limit the first edge-fixing plate 502 when it moves to prevent the first edge-fixing plate 502 from shaking. The top of the mounting base 3 is fixedly connected to a second edge-fixing plate 503. The second edge-fixing plate 503 can fix the edge of the book, thereby providing a clear side positioning reference for the book and preventing the book from shifting left and right during the punching process, ensuring that the spine shape and hole position are consistent with the design standards.

[0043] like Figure 1 , Figure 2 and Figure 5 As shown, the clamping assembly 6 includes a movable plate 601, on which a second threaded rod 602 is threadedly connected. The second threaded rod 602 can move on the movable plate 601 via the thread. A pressing plate 603 is rotatably connected to the bottom of the second threaded rod 602. The movement of the second threaded rod 602 can drive the pressing plate 603 to move up and down. The up and down movement of the pressing plate 603 can fix the book, thereby fixing the book as a whole on the mounting base 3. This can offset the impact and vibration during drilling by the drilling machine, and prevent the book from delaminating, the page edges from curling, or the hole position from shifting. A soft pad is provided at the bottom of the pressing plate 603, which can protect the book and prevent it from being damaged.

[0044] like Figure 2 , Figure 6 , Figure 7 and Figure 8As shown, the drive assembly 7 includes a motor 701. The bottom of the mounting base 3 is detachably connected to the top of the motor 701, allowing the motor 701 to be mounted on the mounting base 3. A drive bevel gear 702 is fixedly connected to the rotating shaft of the motor 701, enabling the motor 701 to drive the drive bevel gear 702 and thus rotate it. A third threaded rod 704 is rotatably connected to the mounting base 3, allowing a driven bevel gear 703 to rotate on the mounting base 3. The bottom of the third threaded rod 704 is fixedly connected to the driven bevel gear 703, and its rotation drives the third threaded rod 704 to rotate. The driven bevel gear 703 meshes with the drive bevel gear 702, and its rotation enables the driven bevel gear 703 to rotate, which in turn enables the third threaded rod 704 to rotate. The outer wall of the third threaded rod 704 is threadedly connected to a hole on the movable plate 601. The rotation of 04 enables the movement of the movable plate 601. A first gear 705 is fixedly connected to the outer wall of the shaft of the motor 701. The motor 701 drives the first gear 705 to rotate. A second gear 706 is rotatably connected to the bottom of the mounting base 3. The second gear 706 meshes with the first gear 705. The rotation of the first gear 705 enables the rotation of the second gear 706. The inner wall of the second gear 706 has a slot 707. Multiple slots 707 are provided inside the second gear 706. A disc 708 is rotatably connected to the bottom of the mounting base 3. A first spring telescopic rod 709 is fixedly connected to the disc 708. The first spring telescopic rod 709 is mounted on the disc 708. A locking block 710 is fixedly connected to the telescopic end of the first spring telescopic rod 709. The locking block 710 can slide on the first spring telescopic rod 709. A reciprocating screw 711 is fixedly connected to the outer wall of the disc 708. The rotation of the disc 708 enables the rotation of the reciprocating screw 711.

[0045] like Figure 2 , Figure 7 and Figure 8 As shown, a second spring telescopic rod 712 is fixedly connected to the bottom of the mounting base 3. Multiple second spring telescopic rods 712 are provided, and a ball is fixedly connected to the telescopic end of each second spring telescopic rod 712. The ball at the telescopic end of the second spring telescopic rod 712 fits into the groove on the disc 708. The cooperation between the ball on the second spring telescopic rod 712 and the groove on the disc 708 can stabilize the disc 708, thereby preventing unnecessary rotation of the disc 708 during use. This prevents the rotation of the disc 708 from driving the reciprocating screw 711, thus avoiding affecting the stability of the placement plate 9.

[0046] like Figure 5As shown, a guide rod 713 is fixedly connected to the top of the mounting base 3. One guide rod 713 is provided. The outer wall of the guide rod 713 fits into the hole provided on the moving plate 601. The guide rod 713 can limit the moving plate 601. The outer wall of the guide rod 713 fits into the hole provided on the pressing plate 603. The guide rod 713 can limit the pressing plate 603. In this way, the guide rod 713 prevents the moving plate 601 and the pressing plate 603 from shaking when moving, thereby avoiding affecting the clamping of the book by the pressing plate 603.

[0047] like Figure 2 , Figure 6 and Figure 7 As shown, the unloading assembly 8 includes two guide plates 801, each with a groove. The top of the guide plate 801 is fixedly connected to the bottom of the mounting base 3. A moving rod 803 is mounted on the guide plate 801 via the groove. The moving rod 803 can slide on the guide plate 801. A moving frame 802 is threadedly connected to the outer wall of the reciprocating screw 711. The rotation of the reciprocating screw 711 can move the moving frame 802. The groove on the moving frame 802 is slidably connected to one end of the moving rod 803. The movement of the moving frame 802 can slide on the guide plate 801. The movement of the moving frame 802 can drive the moving frame 802 to move, thereby automatically removing the processed books from the mold, significantly shortening the processing cycle of a single product, and thus improving processing efficiency and continuity.

[0048] Working principle:

[0049] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, this ancient thread binding punching device for special processes of irregularly shaped books is used by installing the equipment in the required position and inspecting it. After the equipment inspection is completed, the staff can install a suitable box under the base 1 to collect the books. When the staff needs to punch holes in the books, the pressing plate 603 is moved by rotating the second threaded rod 602 according to the thickness of the books, so as to adapt to books of different thicknesses. At the same time, the height of the sliding sleeve 402 can be adjusted by the bolt 403 to facilitate the fixation of the spine. Meanwhile, the first fixed edge plate 502 is moved by rotating the first threaded rod 501 to adapt to the width of the books.

[0050] The staff installs the books onto the placement plate 9 using the cooperation of the first fixed edge plate 502 and the second fixed edge plate 503, and installs one end of the spine into the inside of the template 405. After the books are installed, the staff starts the motor 701. The motor 701 drives the third threaded rod 704 to rotate through the driving bevel gear 702 and the driven bevel gear 703. The rotation of the third threaded rod 704 drives the moving plate 601 to move, thereby clamping the books through the pressing plate 603. After the books are clamped, holes can be punched in the books using the punch 2.

[0051] After the book is punched, the motor 701 drives the active bevel gear 702 to reverse, which in turn drives the driven bevel gear 703 and the third threaded rod 704 to reverse, thereby causing the moving plate 601 to move the pressing plate 603, thus releasing the book. At the same time, the motor 701 also drives the second gear 706 to rotate through the first gear 705. The rotation of the second gear 706 is engaged by the locking block 710 and the locking slot 707, thereby causing the disc 708 to rotate. The rotation of the disc 708 drives the moving frame 802 to move left and right through the reciprocating screw 711. The left and right movement of the moving frame 802 drives the moving rod 803 to move through the guide plate 801, thereby unloading the book and facilitating the punching of the book.

[0052] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
