[0002] In the production process of hardcover books, applying adhesive backing is a crucial step, which directly affects the binding quality and durability of the book.

[0003] The traditional gluing process for hardcover books relies heavily on manual labor, including meticulous paper stacking and compacting steps. This process involves arranging the individual sheets cut by a paper cutter into neat stacks, with the height of each stack typically limited to approximately 500 mm to ensure ease of operation and even distribution of glue.

[0004] The stacking of sheets requires extreme care to ensure the front and back of each sheet are precisely aligned. Heavy objects are then used to compact the stack and reduce the gaps between sheets. These steps are not only time-consuming but also require great skill, as any unevenness can lead to uneven glue application, affecting the strength of the spine and the overall appearance of the book. Furthermore, manual operation is prone to fatigue and can lead to a lack of consistency, especially in mass production. Utility Model Content

[0031] The present application will be further described below in detail through specific embodiments in conjunction with the accompanying drawings.

[0032] In the description of this application: unless otherwise specified, the meaning of "plurality" is two or more. The terms "first", "second", "third", etc. in this application are intended to distinguish the objects referred to and do not have any special meaning in terms of technical connotation (for example, they should not be understood as emphasizing the importance or order, etc.). Expressions such as "including", "comprising", "having", etc. also mean "not limited to" (certain units, components, materials, steps, etc.).

[0033] The terms such as "upper", "lower", "left", "right", "middle", etc. cited in this application are usually used to indicate the general relative position relationship for the convenience of intuitive understanding by referring to the drawings, and are not absolute limitations on the position relationship in the actual product.

[0034] A glue brushing and tightening device, refer to Figure 1-Figure 3 The structure comprises a lower support 1, an upright post 2, a straightening mechanism, and a pressing mechanism. The lower end of the upright post 2 is rotatably connected to the front end of the lower support 1. A rotating rod 3 is also vertically fixed to the bottom front side of the upright post 2. The rotating rod 3 can rotate relative to the lower support 1 along with the upright post 2. Two upright posts 2 and two rotating rods 3 are provided, one at the left and right ends of the lower support 1.

[0035] The straightening mechanism includes a positioning assembly and a vibration motor 4. The positioning assembly is mounted on the vertical pole 2 and is used to position the paper stack. Specifically, the positioning assembly includes a base 5, a main board 6, a side panel 7, and an upper panel 8. The main board 6 is fixedly mounted on the front side of the vertical pole 2 and is parallel to the vertical pole 2, and is used to support the back of the paper stack. The base 5 is mounted on the rotating rod 3. A plurality of support plates 9 are provided at the bottom of the base 5. The positions of the support plates 9 and the rotating rod 3 are staggered to avoid interference. The provision of the support plates 9 can raise the base 5 above the ground or platform for easy access. The side panel 7 is provided on one side of the main board 6 and is perpendicular to the main board 6 and the base 5. A space for the paper stack to be placed is formed between the base 5, the side panels 7, and the main board 6, and the paper stack is positioned on three sides respectively. The upper panel 8 is parallel to the base 5 and is used to press the paper stack from above.

[0036] To facilitate paper stack placement, the side panels 7 are designed to be movable. Specifically, a transverse support 10 is fixed to one side of the upright 2. A telescopic cylinder 11 is mounted on this support 10 to move the side panels 7 forward and backward. Before placing the paper stack, the side panels 7 are first moved to the rear of the main board 6. After the paper stack is placed on the main board 6 and the base 5, the side panels 7 are moved forward to position the stack from one side.

[0037] To achieve the rotation of the upright 2, an electric cylinder 12 can be installed between the lower support 1 and the upright 2. The two ends of the electric cylinder 12 are hinged to the lower support 1 and the upright 2, respectively. To achieve the rotation of the upright 2, there is a certain distance between the hinge point of the electric cylinder 12 and the upright 2 and the hinge point of the upright 2 and the lower support 1. The electric cylinder 12 can drive the upright 2 to rotate.

[0038] When placing a paper stack, first place the base support 5 on the rotating rod 3 and hold it against the main plate 6. Then, using an electric steel, the vertical rod 2 drives the main plate 6 to rotate backward a certain angle, tilting the main plate 6 and the base support 5. The paper stack is placed on the main plate 6 and the base support 5, and the telescopic cylinder 11 drives the side plate 7 forward, so that the bottom, rear, and one side of the paper stack are all pressed tightly together to achieve preliminary straightening.

[0039] Furthermore, a vibration motor 4 is mounted on the rear side of the upright 2 to drive the positioning assembly (main board 6) and the paper stack to vibrate together. After the paper stack undergoes the aforementioned initial straightening operation, the electric cylinder 12 drives the upright 2 to rotate further backward, increasing the tilt angle of the paper stack. The vibration motor 4 is then turned on, and the vibration process further straightens the paper stack, completing the operation.

[0040] Reference Figure 1 、 Figure 4-Figure 5 The pressing mechanism is installed on the vertical pole 2 and includes a rope 13 and an elastic component. The rope 13 is used to bundle the positioning component and the paper stack, and the elastic component is used to adjust the tightness of the rope 13.

[0041] The tensioning assembly includes a housing 14, a movable plate 15, a rack 16, and a spindle 17. The movable plate 15 is positioned on one side of the housing 14 and can be moved away from or toward the housing 14. A rack 16 is positioned between the movable plate 15 and the housing 14, with one end of the rack 16 inserted into the housing 14. To enhance the stability of the movable plate 15, multiple telescopic rods 18 are positioned between the movable plate 15 and the housing 14. The telescopic rods 18 extend and retract parallel to the direction of movement of the rack 16, thereby maintaining the stability of the movable plate 15.

[0042] The main shaft 17 is rotatably connected to the interior of the box body 14 and is perpendicular to the rack 16. A gear 19 and a wire pulley 20 are provided on the main shaft 17. The gear 19 is rotatably connected to the main shaft 17 and meshes with the rack 16. The rack 16 moves downward to drive the gear 19 to drive the main shaft 17 in forward rotation, while the rack 16 moves upward to drive the gear 19 in reverse rotation. The wire pulley 20 is fixed to the main shaft 17 and is used to wind the rope 13. Openings 21 for the rope 13 to pass through are opened on both sides of the box body 14 perpendicular to the main shaft 17. The two ends of the rope 13 pass through the openings 21 and are manually clamped on the base 5.

[0043] Specifically, grooves are provided on the bottom surfaces of the left and right sides of the base 5. When securing the rope 13, a stick can be tied to the end of the rope 13 and inserted into the groove to clamp the end of the rope 13 onto the base 5. Correspondingly, slots for inserting the rope 13 are provided on the left and right sides of the base 5. Once the stick is inserted into the groove, the rope 13 is also inserted into the slot instead of being wrapped around the end of the base 5. This arrangement helps the rope 13 to be closer to the surface of the paper stack, thereby improving the compression effect.

[0044] To reduce wear during the tensioning of the rope 13, pulleys 22 are installed on both sides of the upper plate 8. The axis of the pulleys 22 is perpendicular to the extension direction of the rope 13, and the rope 13 can be wound around the peripheral walls of the pulleys 22. This converts sliding friction into rolling friction, reducing friction and increasing the life of the rope 13.

[0045] Furthermore, the main shaft 17 is also provided with a ratchet 23, a first rotating disk 24, and a second rotating disk 25. The ratchet 23 and the second rotating disk 25 are fixed to the main shaft 17. The first rotating disk 24 is rotatably connected to the main shaft 17, and the ratchet 23 is located between the first rotating disk 24 and the second rotating disk 25. The second rotating disk 25 is rotatably connected to the side of the first rotating disk 24. The end of the pawl 26 can engage with the ratchet 23 to prevent the ratchet 23 from driving the main shaft 17 in reverse. With the cooperation of the ratchet 23 and the pawl 26, the main shaft 17 cannot rotate, which also limits the rotation of the wire reel 20, thereby ensuring that the rope 13 can remain taut.

[0046] Furthermore, a latch 27 is fixed to the first rotating disk 24. The end of the latch 27 extends toward and contacts the pawl 26. A handwheel 28 is also rotatably connected to the main shaft 17. The handwheel 28 is fixedly connected to the first rotating disk 24 and rotates synchronously. A release lever 29 is fixed to the handwheel 28. Both the release lever 29 and the handwheel 28 are located outside the housing 14.

[0047] After the paper stack is glued, the release lever 29 is actuated to drive the clamping column 27 to drive the pawl 26 away from the ratchet 23, and the rope 13 is automatically loosened, so that the paper stack can be removed.

[0048] Furthermore, in order to prevent the movable plate 15 from loosening and the rack 16 from moving up to drive the gear 19 to reverse, a one-way bearing is provided between the gear 19 and the main shaft 17. The one-way bearing is used to limit the main shaft 17 from reversely rotating with the gear 19. The provision of the one-way bearing can further limit the main shaft 17.

[0049] Corresponding to the pressing mechanism, an upper support 30 is installed on the top of the vertical rod 2 , and a pressing cylinder 31 is installed on the front side of the upper support 30 . The pressing cylinder 31 is used to drive the moving plate 15 to approach the box body 14 .

[0050] During implementation, after the paper stack is placed, the upper plate 8 is pressed against the top of the paper stack, the side plate 7 is retracted to the rear of the main plate 6, and the compression assembly and rope 13 are placed above the upper plate 8, with the box body 14 close to the upper plate 8 and the movable plate 15 above the box body 14. The rope 13 is pulled outward, and the ends of the rope 13 are clamped to the ends of the base 5. During this process, it is necessary to ensure that the rope 13 is as close to the paper stack as possible without being too loose. After the ends of the rope 13 are fixed, the compression cylinder 31 drives the movable plate 15 downward to press against the box body 14, driving the rack 16 downward. Under the meshing action, the gear 19 drives the main shaft 17 to rotate forward. The rotation of the main shaft 17 drives the wire wheel 20 to rotate forward, winding and tightening the rope 13. After tightening the rope 13, the paper stack, compression assembly, and compression mechanism can be removed. After the glue is applied, the rope 13 is loosened by the release lever 29, and the paper stack can be removed.

[0051] The technical features of the above embodiments can be combined arbitrarily (as long as there is no contradiction in the combination of these technical features). In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.
