Description

Technical Field

[0001] This utility model relates to the field of book block processing equipment, and in particular to a drying mechanism for applying glue to the side of a book block. Background Technology

[0002] The book block is made up of dozens or even hundreds of sheets of paper stacked together. In the production process of the book block, applying glue to the sides is an essential step. After applying the glue, the glue needs to be dried to ensure the quality and stability of the book block.

[0003] However, existing glue-applying and drying mechanisms often employ simple mechanical blocking and other positioning methods. Since the size of the book block varies significantly depending on the book's specifications, the positions of the baffles in existing mechanical blocking and positioning mechanisms are mostly fixed by welding or manually adjusted by bolts. Manual adjustment requires stopping the machine, removing the bolts, moving the baffle, and re-fixing it, which is time-consuming. Furthermore, the adjustment accuracy depends on the operator's experience and is prone to deviation. In production scenarios involving batch switching of different sized book blocks, frequent machine stops for adjustment can lead to a decrease in production line efficiency and fail to meet the demands of modern continuous production. Therefore, to address the above issues, this utility model provides a drying mechanism for applying glue to the side of the book block. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a drying mechanism for applying glue to the side of a book block.

[0005] This utility model is achieved through the following technical solution:

[0006] A drying mechanism for applying glue to the side of a book block includes a fixed frame, a conveyor belt mounted on one side of the fixed frame, two fixed frames fixedly mounted on the top of the fixed frame, and a positioning mechanism between the two fixed frames. The positioning mechanism includes a connecting frame fixedly mounted between the two fixed frames, a T-shaped slider slidably mounted inside the connecting frame, an electric telescopic rod fixedly mounted at the bottom of the T-shaped slider, a fixed plate fixedly mounted at one end of the electric telescopic rod, multiple connecting cylinders fixedly mounted at the bottom of the fixed plate, connecting rods slidably mounted inside the connecting cylinders, a pressure plate fixedly mounted at one end of the connecting rods, and multiple springs fixedly mounted between the fixed plate and the pressure plate. The springs are sleeved on the surfaces of the connecting cylinders and connecting rods, and a rubber layer is fixedly mounted at the bottom of the pressure plate.

[0007] As can be seen, the above technical solutions can accurately fix the book block, prevent displacement during drying, and provide gentle elasticity to avoid excessive compression of the book block, thereby improving the quality of book block glue drying and work efficiency.

[0008] Optionally, in one possible embodiment of a drying mechanism for applying glue to the side of a book block, two protruding plates are fixedly provided on both sides of the pressure plate, and a guide rod is fixedly provided on the top of the protruding plate; a guide sleeve is sleeved on the surface of the guide rod, the guide sleeve is provided on both sides of the fixed plate, and a limit block is fixedly provided at one end of the guide rod.

[0009] As can be seen, the above technical solution improves the safety of structural operation. The limiting block at one end of the guide rod can prevent the guide rod from slipping off the guide sleeve, prevent the component from falling off and being damaged, ensure the stable operation of the guide structure, and indirectly improve the reliability of the positioning and drying process.

[0010] Optionally, in one possible embodiment of a drying mechanism for gluing the side of a book block, a drying box is fixedly installed on the inner wall of the conveyor belt. Multiple ventilation heads are fixedly connected to one side of the drying box, and multiple conveying pipes are connected through the other side of the drying box. One end of each conveying pipe passes through a fixed frame and extends outward from the fixed frame. A connecting pipe is fixedly connected to one end of the conveying pipe. A hot air blower is fixedly installed on the top of the fixed frame, and the output end of the hot air blower is connected through the connecting pipe. A stepper motor is fixedly installed on one side, and a threaded rod is fixedly installed at the output end of the stepper motor. The threaded rod is threadedly connected to a T-shaped slider.

[0011] As can be seen, the above technical solution features efficient hot air delivery, providing sufficient heat for the drying of the book block adhesive. Moreover, the multiple ventilation heads on one side of the drying box can evenly blow hot air onto the glued area of ​​the book block, avoiding insufficient drying in certain areas and improving the drying quality.

[0012] The beneficial effects of this utility model are:

[0013] This utility model employs a positioning mechanism that ensures precise and stable positioning. A stepper motor drives a threaded rod, which in turn drives a T-shaped slider to adjust its position. This, combined with an electric telescopic rod, moves the pressure plate downward, accurately aligning with and fixing the book block. This prevents the book block from shifting during drying, ensuring uniform drying and effectively protecting the book block. The rubber layer at the bottom of the pressure plate is elastic, preventing damage to the book block surface. When the spring is compressed, it generates a gentle elastic force that both securely fixes the book block and prevents excessive pressure that could damage it, thereby improving the quality and efficiency of the book block gluing and drying process.

[0014] Meanwhile, the hot air generated by the hot air blower reaches the drying box directly through the connecting pipe and the conveying pipe. The conveying path is short and well-sealed, reducing heat loss and improving heat utilization efficiency. Secondly, the drying is uniform and thorough. The multiple ventilation heads of the drying box can blow hot air evenly, and the stepper motor drives the threaded rod to make the T-shaped slider carry the book block horizontally. In conjunction with the synchronous operation of the conveyor belt, the relative position of the book block and the ventilation head is adjusted to ensure that the glued area is covered by hot air from all directions, avoiding drying dead corners and further improving the overall quality of the book block glued drying operation.

Therefore, they should not be construed as limitations on the utility model.

[0023] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0024] Example 1: As Figure 1-5 As shown, this embodiment provides a drying mechanism for applying glue to the side of a book block, including a fixed frame 1, a conveyor belt 2 installed on one side of the fixed frame 1, two fixed frames 3 fixedly installed on the top of the fixed frame 1, and a positioning mechanism provided between the two fixed frames 3.

[0025] The positioning mechanism includes a connecting frame 4 fixedly disposed between two fixed frames 3. A T-shaped slider 5 is slidably disposed inside the connecting frame 4. An electric telescopic rod 6 is fixedly disposed at the bottom of the T-shaped slider 5. A fixed plate 7 is fixedly disposed at one end of the electric telescopic rod 6. Multiple connecting cylinders 8 are fixedly disposed at the bottom of the fixed plate 7. A connecting rod 9 is slidably disposed inside the connecting cylinder 8. A pressure plate 10 is fixedly disposed at one end of the connecting rod 9. Multiple springs 11 are fixedly disposed between the fixed plate 7 and the pressure plate 10. The springs 11 are sleeved on the surfaces of the connecting cylinders 8 and the connecting rods 9. A rubber layer 12 is fixedly disposed at the bottom of the pressure plate 10. Two protruding plates 13 are fixedly disposed on both sides of the pressure plate 10. A guide rod 14 is fixedly disposed at the top of the protruding plate 13. A guide sleeve 15 is sleeved on the surface of the guide rod 14. The guide sleeve 15 is disposed on both sides of the fixed plate 7. A limit block 16 is fixedly disposed at one end of the guide rod 14.

[0026] As can be seen, in the above technical solution, the worker places the glued book block on the conveyor belt 2, starts the conveyor belt 2 at low speed to move the book block towards the drying operation area, and when the book block is close to the positioning area on the side of the connecting frame 4, the conveyor belt 2 stops, first starts the stepper motor 22, which drives the threaded rod 23 to rotate, so that the T-shaped slider 5 slides in the connecting frame 4, adjusts the electric telescopic rod 6 and so on to align with the book block, then starts the electric telescopic rod 6 again, which extends and moves the fixing plate 7 and so on downward, the guide rod 14 slides along the guide sleeve 15 and the anti-pressure plate 10 tilts, the limit block 16 prevents slippage, the rubber layer 12 touches the book block first, and continues to move downward so that the connecting rod 9 retracts into the connecting cylinder 8, the spring 11 compresses to produce elastic force, and the pressure plate 10 gently presses the book block to prevent displacement during drying.

[0027] Usage process: The staff places the book block with the side glue applied on the surface of the conveyor belt 2, starts the drive device of the conveyor belt 2, and the conveyor belt 2 starts to run at a stable low speed, moving the book block towards the drying operation area between the two fixed frames 3. When the book block is about to reach the positioning area on one side of the connecting frame 4, the conveyor belt 2 stops running, the book block stops moving, and the positioning mechanism is ready to be activated.

[0028] Before the positioning mechanism is started, the stepper motor 22 on one side of the connecting frame 4 is started. The stepper motor 22 starts to run, and its output end drives the threaded rod 23 to rotate synchronously. Since the threaded rod 23 is threadedly connected to the T-shaped slider 5, the rotation of the threaded rod 23 will be converted into the sliding of the T-shaped slider 5 inside the connecting frame 4. By controlling the rotation direction of the stepper motor 22, the position of the T-shaped slider 5 is adjusted so that the electric telescopic rod 6, the fixing plate 7 and other components below are aligned with the top of the book block that is about to be reached, and the position adjustment is made for accurate positioning.

[0029] Next, the electric telescopic rod 6 is started. The electric telescopic rod 6 begins to extend, and one end of it drives the fixed plate 7 to move downward. The fixed plate 7 simultaneously drives the multiple connecting cylinders 8, connecting rods 9, pressure plate 10 at the bottom, and springs 11 sleeved on one side of the connecting cylinders 8 and connecting rods 9 to move downward.

[0030] As the pressure plate 10 moves downward, the guide rods 14 on the top of the protruding plates 13 fixed on both sides of the pressure plate 10 will slide along the guide sleeves 15. The guide sleeves 15 are fixed on both sides of the fixed plate 7. The cooperation between the guide rods 14 and the guide sleeves 15 plays a guiding role, preventing the pressure plate 10 from tilting during the up and down movement, and ensuring that the pressure plate 10 always moves downward in a horizontal state. At the same time, the limiting block 16 at one end of the guide rod 14 can prevent the guide rod 14 from slipping out of the guide sleeves 15, ensuring the stable operation of the guiding structure.

[0031] As the electric telescopic rod 6 continues to extend, the rubber layer 12 at the bottom of the pressure plate 10 first contacts the top of the book core. Since the rubber layer 12 has a certain elasticity, it can avoid damaging the surface of the book core. As it continues to move downward, the book core generates an upward reaction force on the pressure plate 10, causing the connecting rod 9 to slide into the connecting cylinder 8. At the same time, the spring 11 between the fixing plate 7 and the pressure plate 10 is compressed. The elastic force generated by the spring 11 acts on the pressure plate 10, so that the pressure plate 10 can press the book core tightly and gently on the conveyor belt 2, completing the positioning and fixing of the book core, and preventing the book core from shifting during the subsequent drying process and affecting the drying effect.

[0032] Example 2: Figure 3-5 As shown, this embodiment provides a drying mechanism for gluing the side of a book block. A drying box 17 is fixedly installed on the inner wall of the conveyor belt 2. Multiple ventilation heads 18 are fixedly connected to one side of the drying box 17, and multiple conveying pipes 19 are connected through the other side of the drying box 17. One end of the conveying pipe 19 passes through the fixed frame 3 and extends to the outside of the fixed frame 3. A connecting pipe 20 is fixedly connected to one end of the conveying pipe 19. A hot air blower 21 is fixedly installed on the top of the fixed frame 3. The output end of the hot air blower 21 is connected through the connecting pipe 20. A stepper motor 22 is fixedly installed on one side of the connecting frame 4. A threaded rod 23 is fixedly installed on the output end of the stepper motor 22. The threaded rod 23 is threadedly connected to the T-shaped slider 5.

[0033] As can be seen, in the above technical solution, the hot air blower 21 on the fixed frame 3 is started, and the hot air enters the drying box 17 on the inner wall of the conveyor belt 2 through the connecting pipe 20 and the conveying pipe 19. Then, multiple ventilation heads 18 blow the hot air evenly onto the glued area of ​​the book core for drying. During drying, the stepper motor 22 starts synchronously with the conveyor belt 2, driving the threaded rod 23 to rotate, so that the T-shaped slider 5 carries the book core horizontally to ensure that the glued area is fully heated. After drying reaches the standard, the electric telescopic rod 6 shortens, the pressure plate 10 separates the book core, the stepper motor 22 drives the T-shaped slider 5 to reset, and finally the conveyor belt 2 conveys the book core out, and the process ends.

[0034] Usage process: After the book block is positioned, start the hot air blower 21 at the top of the fixed frame 3. The hot air blower 21 starts working and the generated hot air is delivered from its output end to the connecting pipe 20. Since the connecting pipe 20 is connected to the conveying pipe 19, and one end of the conveying pipe 19 passes through the fixed frame 3 and is connected to the drying box 17 fixed to the inner wall of the conveyor belt 2, the hot air enters the conveying pipe 19 through the connecting pipe 20 and is then delivered to the inside of the drying box 17 by the conveying pipe 19. Multiple ventilation heads 18 connected and fixed on one side of the drying box 17 blow the hot air in the drying box 17 evenly out and blow it toward the glued part on the side of the book block to dry the glue.

[0035] During the drying process, the stepper motor 22 and the conveyor belt 2 start simultaneously to achieve synchronous movement, which drives the threaded rod 23 to rotate, causing the T-shaped slider 5 to drive the electric telescopic rod 6, the fixing plate 7 and the positioned book block to move horizontally, thereby adjusting the relative position of the book block and the ventilation head 18 to ensure that the glued parts of the book block can be fully dried by hot air.

[0036] Once the glue on the book block has dried to the preset requirements, the electric telescopic rod 6 shortens, causing components such as the fixing plate 7, connecting cylinder 8, connecting rod 9, and pressure plate 10 to move upward. The pressure plate 10 separates from the book block, releasing the positioning and fixing of the book block. At the same time, the stepper motor 22 runs, driving the threaded rod 23 to rotate, causing the T-shaped slider 5 to slide inside the connecting frame 4 and return to its initial position, preparing for the drying of the next book block.

[0037] Finally, conveyor belt 2 transports the dried book block from the positioning drying area, where staff can perform subsequent processing on the dried book block. This completes the entire workflow of applying glue and drying the side of a book block.

[0038] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
