Description

Technical Field

[0001] This utility model relates to the technical field of perfect binding of books in the printing industry, and in particular to a spine pressing machine structure for spine forming. Background Technology

[0002] In the field of printing and binding, perfect binding is a common method, widely used for books, magazines, albums, and other printed materials due to its sturdy binding, easy browsing, and neat appearance. The complete perfect binding process encompasses six key stages: pre-binding preparation, collating, spine milling and roughening, gluing and binding, pressing and shaping, and trimming. In the gluing and binding stage, hot melt adhesive is evenly applied to the spine surface, and the book block is quickly pressed down to ensure full contact between each page and the adhesive. Adhesive is also applied to the inside of the cover corresponding to the spine, and the front and back pages of the book block are precisely aligned and quickly glued together. Subsequently, in the pressing and shaping stage, the glued book is placed in a pressing machine, and a uniform pressure of 5-15 kg / cm² is applied according to the paper thickness, maintained for 10-30 minutes to ensure the hot melt adhesive cools and cures.

[0003] However, traditional spine pressing machines currently on the market are mainly suitable for shaping and pressing high-end books such as leather-bound and hardcover books during the gluing process. These machines have complex overall structures, involving numerous precision mechanical components and automated control systems, resulting in high manufacturing costs. For small printing plants, their printing business typically involves small batches, especially orders for thinner books and brochures, which have lower costs. In this situation, purchasing traditional spine pressing machines not only requires a large upfront investment, tying up significant operating capital, but also suffers from cumbersome adjustment procedures for different specifications and batch sizes, making it difficult to meet the frequent and rapid adjustment needs of small-batch production. This results in high costs and low production efficiency for small printing plants when facing such binding business, putting them at a disadvantage in market competition. Therefore, developing a spine pressing machine with a simple structure, low cost, and flexible adaptation to small-batch production is of significant practical importance. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0005] This utility model provides a spine pressing machine structure for book spine forming, including a frame, a gantry frame fixed to both sides of the top of the frame, an execution component fixed to the crossbeam of the gantry frame, and a pressure plate assembly driven by the drive end of the execution component; a support plate is laid on the top of the frame to form an operating platform, a book mold is placed on the support plate, and multiple perfect bound books are placed vertically and closely together inside the book mold, with the spine of the perfect bound books in an upward position, so that the pressure plate assembly, driven by the execution component, performs a pressing and shaping operation on the spine.

[0006] The execution component includes an actuator and a connector. The actuator is fixed to the crossbeam of the gantry frame, one end of the connector is fixed to the drive end of the actuator, and the other end of the connector is fixed to the pressure plate assembly.

[0007] The connector is configured as a floating joint, with the rod end fixed to the drive end of the actuator and the load side fixed to the pressure plate assembly.

[0008] The connector is configured with a spherical bearing, with the inner ring of the spherical bearing fixed to the drive end of the actuator and the outer ring of the spherical bearing fixed to the pressure plate assembly.

[0009] The pressure plate assembly includes a transition steel plate and a wooden pressure plate that are fixedly connected to each other. The transition steel plate is used to fix the connecting parts, and the wooden pressure plate is used to flatten and shape the spine of the book.

[0010] The book mold has a base plate and side plates. At least two side plates are fixed to the base plate and are arranged vertically, thereby forming a space between the two side plates to hold multiple books.

[0011] The book mold also has a back plate, the bottom of which is fixed to the bottom plate, and the two sides of which are fixed to two side plates respectively, and one of the lateral openings formed between the two side plates is sealed.

[0012] It also includes a control pedal, which is connected to the actuator via a control circuit to control the actuator to start.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Structural Optimization and Cost Control: This utility model features a gantry frame mounted on the machine frame, with actuators driving the pressure plate assembly installed at the gantry beams. The overall structural design is simple and clear. Compared to the complex mechanical structure and automated system of traditional flattening machines, this significantly reduces the number of parts and the difficulty of manufacturing processes, effectively lowering the equipment's manufacturing cost. Simultaneously, the gantry frame structure is stable, providing reliable support for the actuators and pressure plate assembly, ensuring the stability of the equipment's operation.

[0015] 2. Parallel Pressing and Improved Binding Quality: By using floating joints or spherical bearings as connecting components, and utilizing their internal spherical bearing structure or the relative oscillation characteristics of the inner and outer rings, multi-angle micro-oscillation and micro-radial displacement can be achieved. This design can precisely compensate for the installation coaxiality error between the actuator drive end and the pressing plate assembly, effectively absorbing the lateral forces or off-center loads generated during the pressing process, ensuring that the pressing plate assembly remains parallel to the spine surface throughout the spine pressing process. This results in a tight fit between the book cover and the book block, effectively eliminating residual air between them, avoiding problems such as spine arching and loose inner pages, and significantly improving the binding quality of perfect-bound books.

[0016] 3. Adaptability and Customization Advantages: The book mold design is flexible, and its base plate and side plates can be quickly customized according to the size of the books or albums to be pressed. The height of the side plates is equal to or slightly less than the height of the books placed in the mold, ensuring that the pressure plate assembly only acts on the spine and avoids damage to the book edges; the spacing between the side plates can be flexibly adjusted according to the total thickness of the books, or an elastic clamping structure can be used to ensure that multiple books fit tightly in the mold and prevent loosening during pressing.

[0017] Therefore, this utility model has a simple structure and low cost. It ensures parallel pressing through floating joints or joint bearings, thereby improving binding quality. The book molds can be customized to meet diverse needs, combining economy and practicality, and are suitable for small-batch production in small printing factories.

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

[0027] Please see Figures 1 to 4 In this embodiment of the present invention, a spine pressing machine structure for book spine forming includes a frame 10, a gantry frame 12 fixedly connected to the top two sides of the frame 10, an execution component 30 fixedly connected to the crossbeam of the gantry frame 12, and a pressure plate component 40 driven by the drive end of the execution component 30; a bearing plate 11 is laid on the top of the frame 10 to form an operating platform, a book mold 20 is placed on the bearing plate 11, and multiple glued books are vertically placed in the book mold 20, with the spine of the glued books in an upward position, so that the pressure plate component 40, driven by the execution component 30, performs a pressing and shaping operation on the spine.

[0028] Specifically, perfect binding is a common binding method, characterized by its sturdy binding, easy page turning, and neat appearance, and is widely used in printed materials such as books, magazines, and albums. The complete binding process can be divided into six main stages: pre-binding preparation, collating, spine milling and roughening, gluing and binding, flattening and shaping, and trimming. In the gluing and binding stage, hot melt adhesive is first evenly applied to the spine surface. After application, the book block is quickly pressed together to ensure that each page is fully in contact with the adhesive. Simultaneously, adhesive is applied to the inside of the cover corresponding to the spine. Then, the cover is precisely aligned with the front and back pages of the book block and quickly glued to it. In the flattening and shaping stage, the glued book is placed in a flattening machine, and uniform pressure is applied (the pressure is adjusted according to the paper thickness, usually 5-15 kg / cm²), maintaining this pressure for 10-30 minutes (the hot melt adhesive needs to cool and cure). However, traditional flattening machines are typically suitable for shaping and flattening high-end books such as leather-bound and hardcover books during the gluing process; their overall structure is relatively complex and costly. For small printing factories, which have small printing batches, especially for thinner books and brochures with lower costs, traditional flatbed presses have too high initial investment and are not easy to adjust quickly for small-batch production, so it is necessary to improve them.

[0029] This invention utilizes a gantry frame 12 mounted on a frame 10, with an actuator 31 installed on the gantry frame 12 to drive the pressure plate assembly 40, allowing it to press against the book mold 20. This flattens and shapes the spine within the book mold 20, ensuring a tight bond between the inner pages and the cover, preventing spine arching and loosening of the inner pages, while maintaining a flat spine. Notably, the book mold 20 can be quickly customized to the specific book or album requiring flattening. Combined with the universal flattening operation of the pressure plate assembly 40, semi-automatic spine flattening and shaping is achieved. Furthermore, its simple structure and flexible operation make it particularly suitable for small-batch production binding operations in small printing factories.

[0030] like Figure 1 and Figure 3 As shown, preferably, the execution component 30 is provided with an actuator 31 and a connector 32. The actuator 31 is fixed to the crossbeam of the gantry frame 12, one end of the connector 32 is fixed to the drive end of the actuator 31, and the other end of the connector 32 is fixed to the pressure plate assembly 40.

[0031] Specifically, an actuator 31 is fixedly installed at the crossbeam position of the gantry frame 12, and the drive end of the actuator 31 maintains vertical movement, thereby driving the pressure plate assembly 40 to perform synchronous vertical movement. Due to installation errors or uneven load force, there may be a slight coaxiality deviation between the drive end of the actuator 31 and the pressure plate assembly 40. Therefore, the deviation is compensated by the connector 32 to ensure that the pressure plate assembly 40 presses in parallel.

[0032] Secondly, since the pressure plate assembly 40 is a planar component, and the pressing and shaping operation of the spine requires ensuring parallel pressing, that is, the pressure plate assembly 40 must always remain parallel to the surface of the object being pressed during the pressing process to avoid tilting caused by installation deviations or uneven force. Therefore, a connector 32 can be provided between the drive end of the actuator 31 and the pressure plate assembly 40. The connecting characteristics of the connector 32 can be used to compensate for the installation coaxiality error between the drive end and the pressure plate assembly 40; at the same time, it can absorb the lateral force or off-center load that may be generated during the pressing process to prevent the pressure plate assembly 40 from tilting.

[0033] Furthermore, the specific fixing methods at both ends of the connector 32 can be achieved using existing technologies such as welding, bolts, snap rings, flanges, or pins, as long as a stable connection is formed, which will not be elaborated further here. The actuator 31 can be a pneumatic, electric, or hydraulic actuator from the prior art, with a cylinder being the preferred choice.

[0034] In another embodiment, such as Figure 1 and Figure 3 As shown, preferably, the connector 32 is configured as a floating joint, with the rod end of the floating joint fixed to the drive end of the actuator 31 and the load side of the floating joint fixed to the pressure plate assembly 40.

[0035] Specifically, in order to optimize the parallel pressing problem between the pressure plate assembly 40 and the spine, the connector 32 is preferably set as a floating joint. The floating joint uses a spherical bearing structure to achieve multi-angle micro-oscillation (usually allowing ±5°~±10° of sway) and micro-radial displacement, which can compensate for the coaxiality error during installation and the off-center load during the pressing process.

[0036] Secondly, by setting a floating joint, the actuator 31 can eliminate the rigid constraint between the drive end of the actuator 31 and the pressure plate assembly 40 during the process of driving the pressure plate assembly 40 to flatten and shape the spine. This ensures that the pressure plate assembly 40 always contacts the spine in a parallel posture, thereby eliminating residual air between the book cover and the book block and ensuring that the book cover and the book block can fit tightly together, making them both firm and flat.

[0037] In addition, the floating joint can also protect the drive end of the actuator 31 from damage by lateral forces and extend the life of the actuator 31.

[0038] In yet another embodiment, such as Figure 1 and Figure 3 As shown, preferably, the connector 32 is provided with a spherical bearing, the inner ring of which is fixed to the drive end of the actuator 31, and the outer ring of which is fixed to the pressure plate assembly 40.

[0039] Specifically, the connector 32 can also be configured with a spherical bearing. The inner ring of the spherical bearing transmits the axial force of the actuator 31 to the spherical bearing, and compensates for the installation deviation between the piston rod and the pressure plate through the relative swing of the inner and outer rings. The outer ring of the spherical bearing evenly applies the force transmitted by the spherical bearing to the pressure plate assembly 40, while allowing the pressure plate assembly 40 to adaptively adjust within a small angle range to ensure parallel contact with the spine of the book.

[0040] Secondly, for example, a radial spherical bearing is installed on the pressure plate assembly 40, and the drive end of the actuator 31 is threaded and connected to the inner ring of the bearing by bolts. The radial spherical bearing allows for a certain angle of oscillation (±3°~±8°) to compensate for installation deviations. The spherical bearing has a higher load-bearing capacity than the floating joint, making it suitable for scenarios with larger pressing forces; its structure is relatively simple and its cost is lower than that of the floating joint.

[0041] In addition, the connection between the bearing and the pressure plate assembly 40 must be firm (such as by welding or fixing with high-strength bolts) to prevent the bearing itself from loosening and affecting the parallelism.

[0042] like Figure 3 As shown, preferably, the pressure plate assembly 40 is provided with a transition steel plate 41 and a wooden pressure plate 42 that are fixedly connected to each other. The transition steel plate 41 is used to fix the connector 32, and the wooden pressure plate 42 is used to flatten and shape the spine of the book.

[0043] Specifically, for the installation of the connector 32, a transition steel plate 41 is preferably provided. The metal material of the transition steel plate 41 facilitates the welding and fixing of the connector 32. For the pressing operation of the spine, a wooden pressing plate 42 made of wood is preferably used. The wooden pressing plate 42 has a certain buffering and elastic deformation capacity, which can apply uniform pressure to the spine, ensuring a tight fit while avoiding damage to the book.

[0044] Secondly, using a wooden pressure plate 42 can reduce the overall weight of the pressure plate assembly 40 and reduce manufacturing costs. The connection between the transition steel plate 41 and the wooden pressure plate 42 is preferably made using a combination of bolts and nuts.

[0045] like Figure 1 and Figure 4 As shown, preferably, the book mold 20 is provided with a base plate 21 and side plates 22, with at least two side plates 22 fixed to the base plate 21 and kept vertically arranged, thereby forming a space for holding multiple books between the two side plates 22.

[0046] Specifically, the spacing (accommodation space width) between the two side plates 22 can be adjusted according to the total thickness of the book, or a flexible clamping structure can be used to ensure that the book fits tightly within the space and avoids loosening during pressing. To flatten and shape the glued area (i.e., the spine) of the perfect-bound book, it is preferable to place the book vertically with the spine facing upwards. To ensure that the book does not fold during the flattening process, it is preferable to use a book mold 20 to clamp multiple books. Therefore, the vertically arranged side plates 22 on the base plate 21 can be used to clamp the books.

[0047] Secondly, the height of the side plate 22 is equal to or slightly less than the height of the book placed in the mold (vertical dimension), ensuring that the pressure plate assembly 40 only acts on the spine of the book and does not contact the edges of the book. This allows the pressure plate assembly 40 to flatten the spine during the flattening process without bending or folding the book and damaging it.

[0048] like Figure 1 and Figure 4 As shown, preferably, the book mold 20 is further provided with a back plate 23. The bottom of the back plate 23 is fixed to the bottom plate 21, and its two sides are respectively fixed to two side plates 22, and one of the lateral openings formed between the two side plates 22 is sealed.

[0049] Specifically, in order to facilitate better positioning of clamping multiple books, it is preferable to seal one of the lateral openings between the two side plates 22, that is, to set up a back plate 23 to seal one of the openings. The back plate 23 is used to abut against the non-spine side of the book to limit the lateral displacement of the book during placement.

[0050] Secondly, in order to facilitate the clamping operation of multiple books, it is necessary to ensure that the other opening of the lateral opening formed by the two side plates 22 remains open, so that the books can be placed into the receiving space of the book mold 20 from the open opening.

[0051] In addition, to facilitate the insertion of multiple books, the preferred book mold 20 is made of an elastic material (such as polyurethane rubber) with a certain degree of elasticity. At the open position, the side plate 22 can be bent to the side to accommodate the books. Vertically, the side plate 22 also has good support force, thereby supporting the pressing of the pressure plate assembly 40.

[0052] like Figure 1 As shown, preferably, it also includes a control pedal 13, which is connected to the actuator 31 via a control line, thereby controlling the actuator 31 to start.

[0053] Specifically, in order to control the actuator 31, a control pedal 13 is preferably provided so that the actuator 31 is started when the control pedal 13 is opened, and then the pressure plate assembly 40 is driven to move the book mold 20, thereby flattening and shaping the spine of the book.

[0054] Secondly, if the actuator 31 is a cylinder, the control pedal 13 starts and stops the cylinder by controlling the opening and closing of the air valve, and the air circuit connection can be done in a conventional way. The control circuit of the control pedal 13 can be set according to the type of actuator 31 used. When the actuator 31 is a cylinder, the control pedal 13 controls the start and stop of the cylinder by controlling the air valve (existing technology). That is, the control circuit of the control pedal 13 can be set to control the air valve in the prior art. The air valve is connected to the cylinder and the external air compressor through pipelines. After the control pedal 13 opens the air valve, the external high-pressure gas is introduced into the cylinder to do work on the cylinder, so that it drives the pressure plate assembly 40 to flatten and shape the spine of the book.

[0055] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
