Description

Technical Field

[0001] This utility model relates to the technical field of children's book production equipment, and in particular to a book core alignment and pressing device for a children's book production line. Background Technology

[0002] Children's book production equipment includes major processes such as cover feeding, cover printing, book block mounting, cover flipping, and flat pressing. At the crucial mounting station, the cover with glue is transported to its position by a conveyor device, while the book block feeding mechanism above it feeds the book block into the conveyor channel via a belt conveyor. The conveyor channel usually consists of two adjustable-spaced vertical plates, and a bottom conveyor belt is typically provided along the path to stably support the book block.

[0003] When the book block reaches the end of the transport channel and is ready to fall and join the cover, a buffer adjustment mechanism is typically installed on one of the uprights to prevent premature slippage and stabilize its position. These mechanisms generally use spring clips as side clamping components. For example, Chinese Patent Publication No. CN111922748A discloses a user-friendly, indentation-free spring clip structure, which includes a lifting device and a spring clip body mounted on the device. The front end of the spring clip body has a resilient, arc-shaped support. The height of the spring clip can be adjusted as a whole using the lifting device.

[0004] However, this type of spring structure with an arc-shaped abutment has significant drawbacks. Because the abutment only forms a linear contact with the side of the book block, the contact area is very limited, causing the book block to easily slip off and resulting in poor clamping performance. More seriously, the localized pressure from the linear contact is high, easily causing dents on the side of the book block, affecting product quality. Furthermore, relying solely on the cushioning effect created by the bending of the spring itself, as the spring deforms over time, it cannot effectively maintain a continuous and stable balanced cushioning and force-relieving effect.

[0005] Therefore, the above problems urgently need to be solved. Utility Model Content

Detailed Implementation

[0046] This utility model provides a book block alignment and pressing device for a children's book production line. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0047] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0048] Please refer to Figures 1 to 5 This embodiment discloses a book block alignment and pressing device for a children's book production line, including a cover conveying mechanism, a book block feeding mechanism 20, a pressing mechanism and a buffer adjustment mechanism 40; the cover conveying mechanism includes a first conveying device 10 that conveys the cover along the X direction.

[0049] Please refer to Figure 1 The book block feeding mechanism 20 includes a second conveying device 21 located above the first conveying device 10 and conveying the book block along the y direction, an inclined guide device 22 located at the discharge end of the second conveying device 21, and a book block feeding device 23 located at the discharge end of the inclined guide device 22. The book block feeding device 23 includes two upright plates 231 mounted above the first conveying device 10 and a conveying channel 232 formed between the two upright plates 231 with an adjustable spacing.

[0050] Please refer to Figure 2 The pressing mechanism includes two pressing devices 30 respectively disposed on two upright plates 231; the pressing device 30 includes a mounting plate 31 fixed to the upright plate 231, a first driver 32 fixed to the mounting plate 31, and a pressing plate 33 connected to the output end of the first driver 32 and used to press the book core in the conveying channel 232 along the z direction to the upper end of the cover conveyed by the first conveying device 10.

[0051] Please refer to Figure 2 The buffer adjustment mechanism 40 includes a second driver 41 fixed to a mounting plate 31 of one of the pressing devices 30 and driven along the Z direction, a sliding seat 42 connected to the output end of the second driver 41, a lower extension arm 43 fixed to the lower end of the sliding seat 42, a mounting rod 44 provided on the lower extension arm 43, and a plurality of buffer members 45 arranged at intervals along the y direction on the mounting rod 44; the buffer member 45 includes a connecting plate 451 fixed to the mounting rod 44, an elastic arm 452 connected to the connecting plate 451, and a contact plate 453 connected to one end of the elastic arm 452 and disposed facing the conveying channel 232; wherein, one side of the book core in the conveying channel 232 abuts against the contact plate 453.

[0052] The production process of this application is as follows: After the cover printed with adhesive is precisely transported to the laminating station by the first conveyor device 10 and positioned at rest, the book block is fed from the upper book block feeding mechanism 20 into the conveying channel 232 between the two upright plates 231. The book block moves along the conveying channel 232 to the end, ready to be bonded to the cover at rest below. At this time, the pressing device 30 starts to operate, and the pressing plate 33 moves vertically downward under the drive of the driver 32, pressing the book block smoothly onto the area of ​​the cover pre-covered with adhesive. Under precise pressure, the two achieve tight bonding and complete the adhesion.

[0053] During the brief, critical phase from when the book block moves to the end of the transport channel 232 until the pressing action of the pressure plate 33 begins, the buffer adjustment mechanism 40 plays a crucial stabilizing role. Its contact plate 453 immediately and gently adheres to the side of the book block upon reaching the end, providing a stable, elastic clamping force through surface contact. This ensures that the book block does not slip or tilt in its pre-positioned state, maintaining the correct posture on the pressing path at all times. This provides the necessary support and positioning for precise and effective pressing and mounting, while simultaneously preventing indentations.

[0054] Please refer to Figures 3 to 5 The buffer adjustment mechanism 40 also includes a pressure adjustment module 46. The pressure adjustment module 46 includes a guide groove 461 located on the lower extension arm 43, a guide rail 462 located on the mounting rod 44 and slidingly engaged with the guide groove 461, a side plate 463 fixed to the lower extension arm 43 and having a screw hole, and an adjustment screw 464 passing through the screw hole and abutting against the mounting rod 44. By turning the adjustment screw 464, the position of the mounting rod 44 along the x-direction (perpendicular to the book block transport direction) can be directly pushed or pulled back, thereby changing the initial contact force between the contact plate 453 and the side of the book block in all buffer components 45. This direct adjustment method, which eliminates the need for disassembly, saves the tedious operation of replacing or adjusting individual buffer components, making it convenient and efficient. More importantly, it can fine-tune the contact pressure in real time for book block products with different thicknesses, hardness, or material requirements. This ensures that it provides sufficient friction and elastic clamping force to prevent the book block from slipping out accidentally, while also avoiding deformation or damage to the book block caused by excessive pressure. This significantly improves the equipment's versatility (compatible with different specifications of book blocks) and the stability of product mounting quality, while reducing debugging time costs and product defect rates.

[0055] Please refer to Figure 1 The second conveying device 21 is a belt conveyor; the inclined guide device 22 includes a first inclined slide 221 located below the discharge end of the second conveying device 21 and connected to the conveying channel 232, and a pushing device 222 located on one side of the first inclined slide 221 for pushing the book block into the conveying channel 232 along the y-direction. The book block delivered by the belt conveyor 21 first falls into the first inclined slide 221 for natural posture adjustment and buffering, and then the pushing device 222 pushes the book block into the conveying channel 232 along the y-direction, realizing automated book block conveying and improving production efficiency.

[0056] Please refer to Figure 1The book block feeding mechanism 20 also includes a translation component 24 for adjusting one of the upright plates 231 along the x-direction. The translation component 24 includes a rack 241 located on the y-direction side of the first conveying device 10, a gear meshing with the rack 241, a connecting rod 242 coaxially driven with the gear, a third driver 243 for driving the connecting rod 242 to rotate, and a bearing 244 fixed to the upright plate 231 and sleeved on the connecting rod 242. By driving the third driver 243 to rotate the connecting rod 242, the gear coaxial with it rotates along the fixed rack 241. The rotational motion of the gear is converted into linear displacement along the rack 241 (i.e., the x-direction), which drives the upright plate 231 connected to it via the bearing 244 to move synchronously. With this structure, precise position adjustment of the upright plate 231 on one side along the x-direction can be achieved, thereby flexibly changing the width of the conveying channel 232. It effectively solves the equipment compatibility problem, enabling the same device to quickly and stably adapt to the conveying needs of book block products of different sizes (especially width differences), significantly improving the flexibility and production efficiency of the production line.

[0057] Please refer to Figure 1 The translation component 24 also includes a first slide rail 245 arranged along the x-direction, with a first slider 246 mounted on the first slide rail 245. A gear is rotated on the first slider 246. The third driver 243 can be a handle connected to one end of the connecting rod 242. When adjustment is needed, the operator can rotate the handle 243, which drives the connecting rod 242 to rotate, causing the gear to roll along the rack 241. Simultaneously, it drives the first slider 246 to move smoothly along the first slide rail 245, ultimately causing the upright plate 231 to slide and adjust precisely. Through manual operation, under the rigid guidance of the slide rail, the width of the conveying channel 232 can be adjusted steplessly and stably, ensuring compatibility and positioning accuracy for different book block sizes.

[0058] Please refer to Figure 2 and Figure 4 The book block loading mechanism 20 also includes a blocking and limiting component 25. The blocking and limiting component 25 includes a second slide rail 251 fixed to the mounting plate 31, a second slider 252 that slides along the second slide rail 251 to adjust its position, a spring 253 fixed to the second slider 252, and a slanted stop 254 connected to one end of the spring 253. The slanted stop 254 is located at the end of the conveying channel 232. When the book block moves to the end of the conveying channel 232, it impacts the inclined surface of the slanted stop 254. The impact force causes the slanted stop 254 to move backward (buffered and absorbed by the spring 253 mounted on it), while its slanted structure guides the book block to slide smoothly and straighten its posture. Finally, under the elastic support provided by the spring 253 and the limiting effect of the slanted stop 254, the book block is stably stopped at a precise position directly opposite the cover below. This component effectively prevents the book block from accidentally slipping due to inertia and avoids rigid collision damage through buffer contact, ensuring the stability and positioning accuracy of the book block before it falls.

Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of this invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this invention.
