Description

Technical Field

[0001] This utility model relates to the field of book page processing technology, and mainly to a drop-type book page delivery structure. Background Technology

[0002] In the production of cardboard books, to improve page performance and facilitate gluing together to form the final book, a roller coating process using gluing rollers and pressure rollers is required to coat the page surface. In existing processes, the gluing roller and pressure roller rotate in opposite directions, clamping the pages. The pages must pass through the gap between the two rollers to transfer the adhesive layer. This physical clamping structure directly disrupts the continuous transport of the pages. This disruption damages the continuity of page transport, easily affecting alignment accuracy. To continue transporting after gluing, readjustment of the alignment position is often necessary to maintain continuity and alignment, impacting production efficiency. Therefore, it is necessary to propose a feeding structure that allows pages to be fed onto subsequent processing mechanisms after gluing, eliminating the need for adjustment. Thus, existing technology requires further improvement and development. Utility Model Content

[0005] As a further improvement to the above technical solution, the flag-pushing component includes: A first support rod and a second support rod are arranged side by side with a gap between them. The extension direction corresponds to the page conveying direction, and the gap width corresponds to the page width. Both the first support rod and the second support rod are located below the conveying gap and are used to support the page.

[0006] As a further improvement to the above technical solution, the flag-pushing component also includes: A bottom pusher flag, located between the first support rod and the second support rod, is used to abut against the end of the book page near the conveying gap; The bottom push flag drive mechanism is used to drive the bottom push flag to move and push the book pages.

[0007] As a further improvement to the above technical solution, the bottom push flag is provided with a protrusion that extends the working surface of the first support rod and the second support rod, and the bottom push flag abuts against the book page through the protrusion; The bottom flag pusher mechanism includes: A bottom-push flag vertical movement mechanism is used to drive the bottom-push flag to move vertically; A bottom pusher flag longitudinal movement mechanism is used to drive the bottom pusher flag to move along the page conveying direction.

[0008] As a further improvement to the above technical solution, the flag-pushing component also includes: The pusher flag, located above the first and second support rods, is used to abut against the end of the book page near the conveying gap; An upward push flag drive mechanism is used to drive the upward push flag to move along the page conveying direction.

[0009] As a further improvement to the above technical solution, the upward flag driving mechanism includes: A conveyor belt extends along the direction of book page transport and corresponds to the first support rod and the second support rod; The second drive mechanism is used to drive the conveyor belt to rotate; The upward-pushing flag is positioned on the conveyor belt.

[0010] As a further improvement to the above technical solution, the flag-pushing component also includes: A delivery conveyor belt is located between the first support rod and the second support rod, and the working surface height of the delivery conveyor belt corresponds to the conveying surface height of the book pages on the first support rod and the second support rod.

[0011] As a further improvement to the above technical solution, the flag-pushing component also includes: The third support rod is disposed between the first support rod and the second support rod, with its extension direction corresponding to the page conveying direction and its height corresponding to the working surfaces of the first support rod and the second support rod; The third support rod adjustment mechanism is used to adjust the position of the third support rod.

[0012] As a further improvement to the above technical solution, the flag-pushing component also includes: The number of adjusting blocks corresponds to the number of the first support rod and the second support rod, and the first support rod and the second support rod are respectively arranged on the two adjusting blocks; The number of adjusting screws corresponds to the number of adjusting blocks, and the adjusting blocks are threadedly engaged with the adjusting screws.

[0014] Beneficial effects: In this invention, by setting the conveyor roller and pressure roller to be rotatable, and with the pressure roller arranged side-by-side below according to the thickness of the book pages, a conveying gap can be formed between them to allow the book pages to pass through. After the book pages are fed into the conveying gap, the conveyor roller and pressure roller can clamp the book pages by abutting against each other. The first drive mechanism drives the conveyor roller to rotate, and the conveyor roller can transport the book pages out of the conveying gap by rotating (at which time the pressure roller rotates in the opposite direction). Since the pressure roller is located below the conveyor roller, the conveying direction of the conveying gap tends to be horizontal. After the book pages are separated from the conveying gap, they can fall relatively horizontally as a whole, ensuring docking accuracy and reducing adjustment steps. The pusher assembly can receive the book pages and push them away from the conveying gap, making it easy to put them into the subsequent book page processing mechanism. Attached Figure Description

Detailed Implementation

[0024] This utility model provides a drop-down page delivery structure. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following provides a more detailed description of this utility model. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit this utility model.

[0025] Reference Figures 1-8 This utility model provides a drop-type page delivery structure, wherein the drop-type page delivery structure includes: Conveyor roller 100 and pressure roller 200 are arranged side by side with intervals, and pressure roller 200 is located below conveyor roller 100; The first drive mechanism is used to drive the conveyor roller 100 to rotate in the opposite direction relative to the pressure roller 200; A conveying gap 110 is formed between the conveying roller 100 and the pressure roller 200 for the pages to abut and pass through. The rotation direction of the conveying roller 100 and the pressure roller 200 corresponds to the conveying direction of the pages. The pusher assembly 300 is located on one side of the output end of the conveying gap 110 and is used to receive the pages and push them away from the conveying gap 110.

[0026] The components of the drop-type page delivery mechanism of this invention can be mounted on the frame, facilitating connection and achieving positional coordination between them.

[0027] In this invention, the conveying roller 100 and the pressure roller 200 are rotatable. The pressure roller 200, positioned side-by-side below the book pages according to their thickness, forms a conveying gap 110 for the pages to pass through. After the pages are fed into the conveying gap 110, the conveying roller 100 and the pressure roller 200 clamp the pages together. The first driving mechanism drives the conveying roller 100 to rotate, allowing the pages to be conveyed out of the conveying gap 110 by rotation (while the pressure roller 200 rotates in the opposite direction). Because the pressure roller 200 is positioned below the conveying roller 100, the conveying direction of the conveying gap 110 is horizontal. After the pages detach from the conveying gap 110, they fall relatively horizontally, ensuring alignment accuracy and reducing adjustment steps. The pusher assembly 300 receives the pages and pushes them away from the conveying gap 110, facilitating their placement in the subsequent page processing mechanism.

[0028] The pressure roller 200 can be height-adjustable, and a separate drive mechanism can be used to drive the pressure roller 200 to move vertically, so as to adjust the interval distance of the conveying gap 110 and the roller pressure of the book pages. The interval distance of the conveying gap 110 can be set according to the thickness of the book pages to ensure that the book pages can pass through.

[0029] The pressure roller 200 can be configured to rotate passively or be driven by a separate drive mechanism. Preferably, the first drive mechanism simultaneously drives the conveyor roller 100 and the pressure roller 200 to rotate in opposite directions; a suitable transmission configuration is sufficient. Driven by the same drive mechanism, the transmission is timely, and the conveyor roller 100 and the pressure roller 200 rotate simultaneously in opposite directions. This results in a more uniform force distribution on the top and bottom surfaces of the book pages, which helps ensure a smooth release of the book pages from the output gap 110.

[0030] The conveyor roller 100 can also abut against a glue-applying roller (set above the conveyor roller 100). After the glue is conveyed to the glue-applying roller, the glue application begins. The conveyor roller 100 has a certain amount of glue on its surface by abutting and rotating. When the book page abuts and passes through the conveyor gap 110, it can pass through the glue through the conveyor roller 100 to achieve glue transfer.

[0031] The design of this invention can achieve a certain flattening effect while gluing the book pages, which helps to ensure the processing accuracy of the book pages.

[0032] In one specific embodiment of this utility model, the flag-pushing assembly 300 includes: The first support rod 310 and the second support rod 320 are arranged side by side with a gap between them. Their extension direction corresponds to the page conveying direction, and the gap width corresponds to the page width. Both the first support rod 310 and the second support rod 320 are located below the conveying gap 110 and are used to support the page.

[0033] The shapes of the first support rod 310 and the second support rod 320 are not limited, and they can contact the page lines or the surface. When in contact with the page, the top surfaces of the first support rod 310 and the second support rod 320 are plate-shaped. At this time, the working surfaces of the first support rod 310 and the second support rod 320 are on the same plane, which can ensure the support effect.

[0034] The first support rod 310 and the second support rod 320 may also be provided with limiting parts, which are respectively set on both sides in the width direction of the book page, which helps to ensure the conveying temperature of the book page and the alignment effect.

[0035] In this invention, by arranging first support rods 310 and second support rods 320 side by side at intervals, with the interval width corresponding to the book pages, the first support rods 310 and second support rods 320 can support both sides of the book pages in the width direction, corresponding to the smooth drop effect of the book pages and promptly carrying the book pages. During the drop, the air pressed down by the book pages can be discharged from the interval in time, and the book pages can easily and smoothly fall directly onto the first support rods 310 and second support rods 320, which helps to maintain the alignment effect. Moreover, the space left between the first support rods 310 and second support rods 320 also facilitates the installation of the push flag assembly 300. The push flag assembly 300 also has a low friction resistance effect when pushing the book pages, which facilitates the pushing and delivery of the book pages. The book pages can be directly placed onto the receiving platform of the subsequent processing mechanism, such as the mounting tray.

[0036] Reference Figures 1-4 In one specific embodiment of this utility model, the flag-pushing assembly 300 further includes: The bottom pusher 350 is located between the first support rod 310 and the second support rod 320, and is used to abut against the end of the book page near the conveying gap 110; Bottom push flag drive mechanism is used to drive the bottom push flag 350 to move and push the book pages.

[0037] In this invention, by setting a bottom pusher 350, after the bottom pusher 350 is raised to the same height as the book page, the bottom pusher 350 is driven by the bottom pusher drive mechanism to move along the conveying direction of the book page. The bottom pusher 350 can contact and push the book page after contact, so as to facilitate subsequent delivery.

[0038] Reference Figure 3 In one specific embodiment of this utility model, the bottom pusher 350 is provided with a protrusion 351 that can extend the working surface of the first support rod 310 and the second support rod 320, and the bottom pusher 350 abuts against the book page through the protrusion 351. The bottom flag pusher mechanism includes: The bottom flag pusher vertical movement mechanism is used to drive the bottom flag pusher 350 to move vertically; The bottom pusher flag longitudinal movement mechanism is used to drive the bottom pusher flag 350 to move along the page conveying direction.

[0039] The vertical direction generally aligns with the transport direction of the book pages. The bottom flag vertical movement mechanism and the bottom flag longitudinal movement mechanism can specifically utilize drive mechanisms such as pneumatic cylinders, hydraulic cylinders, or electric actuators.

[0040] Specifically, the bottom pusher 350 may include a connecting plate and a protrusion 351. The protrusion 351 pushes the book pages, and the connecting plate is driven to move by the bottom pusher drive mechanism. This makes it easy to control the protrusion 351 while taking up less space in the book page conveying channel.

[0041] Specifically, refer to Figure 2 and Figure 3 The number of bottom push flags 350 can be set in two columns corresponding to the first support rod 310 and the second support rod 320. They can be set on the first support rod 310 and the second support rod 320 respectively. The two bottom push flags 350 are set facing each other, and the protrusions 351 on both sides are aligned and contact the two ends of the page width direction respectively.

[0042] Specifically, refer to Figure 2 and Figure 3 The two bottom push flags 350 can be connected to the first support rod 310 and the second support rod 320 respectively by setting a connecting plate. A vertical guide rail is set on the connecting plate, and the bottom push flags 350 are slidably connected to the connecting plate through the vertical guide rail. A longitudinal guide rail is set on the first support rod 310 and the second support rod 320, and the connecting plate is slidably connected to the first support rod 310 and the second support rod 320 through the longitudinal guide rail, which is conducive to realizing the movement of the bottom push flags 350 in the vertical and longitudinal directions.

[0043] Specifically, refer to Figure 2 Furthermore, a longitudinal guide rail can be installed on the frame, through which the first support rod 310 and the second support rod 320 are slidably connected to the frame, further improving the adjustable range of the bottom push flag 350.

[0044] In this invention, after setting a suitable initial position, once the book pages fall onto the first support rod 310 and the second support rod 320, the protrusion 351 extends out of the working surface of the first support rod 310 and the second support rod 320 via the bottom pusher vertical movement mechanism. The protrusion 351 rises to the same height as the book pages, and the bottom pusher 350 moves along the conveying direction of the book pages via the bottom pusher longitudinal movement mechanism. After the protrusion 351 contacts and abuts against the book pages, it pushes the pages for subsequent delivery. After pushing is completed, the protrusion 351 resets, achieving a reciprocating pushing effect.

[0045] Specifically, in this utility model, the conveyor belt 340 and the bottom pusher flag longitudinal moving mechanism can be set with appropriate speeds. Specifically, the pages can be stably conveyed at a lower speed, or the pages can be thrown to the subsequent processing mechanism at a higher speed. The appropriate position and speed can be set to match.

[0046] Reference Figures 5-8 In one specific embodiment of this utility model, the flag-pushing assembly 300 further includes: The pusher flag 330 is located above the first support rod 310 and the second support rod 320, and is used to abut against the end of the book page near the conveying gap 110; The push-up flag drive mechanism is used to drive the push-up flag 330 to move along the page conveying direction.

[0047] In this invention, the push flag 330 is driven by the push flag drive mechanism to move along the conveying direction of the book page. After it comes into contact with one end of the book page near the conveying gap 110, it can be pushed away from the conveying gap 110 so that it can be placed into the subsequent processing mechanism.

[0048] In one specific embodiment of this utility model, the upward flag driving mechanism includes: Conveyor belt 340 extends along the conveying direction of the book pages and corresponds to the first support rod 310 and the second support rod 320; The second drive mechanism is used to drive the conveyor belt 340 to rotate. The upward-pushing flag 330 is set on the conveyor belt 340.

[0049] In this invention, a conveyor belt 340 drives the pusher flag 330 to rotate cyclically. The pusher flag 330, located at the bottom of the conveyor belt 340, can push the book pages through the movement of the conveyor belt 340. After pushing, the pusher flag 330 is reset to one end near the conveyor gap 110 by the conveyor belt 340. Specifically, after the book pages fall onto the first support rod 310 and the second support rod 320 through the conveyor gap 110, by setting appropriate position and conveyor speed, the pusher flag 330 descends to the same height as the book pages when it flips downwards by the conveyor belt 340. After being conveyed, it comes into contact with the book pages, which can effectively ensure conveying efficiency.

[0050] Specifically, the input end of the conveyor belt 340 is positioned close to the conveying gap 110. Multiple push flags 330 can be configured, arranged to correspond to the first support rod 310 and the second support rod 320, typically in two rows, with the push flags 330 in each row aligned to ensure smooth pushing. Within a row of push flags 330, each push flag needs to descend to the same height as the book page. The spacing between two adjacent push flags 330 is set according to the length of the book page to avoid jamming.

[0051] Specifically, both the top push flag 330 and the bottom push flag 350 in this utility model can push the book pages. When using them, one of them can be selected according to the actual situation in order to flexibly adapt to the required delivery effect.

[0052] In one specific embodiment of this utility model, the bottom push flag 330 and the top push flag 350 can be set simultaneously. After the book page falls onto the working surface of the first support rod 310 and the second support rod 320 through the conveying gap 110, the bottom push flag 350 is first driven to move by the bottom push flag driving mechanism. After the bottom push flag 350 pushes the book page to a suitable position, the bottom push flag vertical moving mechanism in the bottom push flag driving mechanism drives the bottom push flag 350 to move downward. The protrusion 351 does not exceed the working surface of the first support rod 310 and the second support rod 320. Then, the top push flag 330 is driven by the top push flag driving mechanism. The top push flag 330 contacts the book page and pushes it out.

[0053] Alternatively, the bottom pusher flag 350 can be driven by an additional circulating conveyor mechanism. This mechanism can be a chain or pulley system. By fixing the bottom pusher flag 350 to the circulating chain or belt, vertical and longitudinal movement of the bottom pusher flag 350 can be achieved. Vertical and longitudinal movement of the upper pusher flag 330 can also be achieved by a drive mechanism such as a cylinder, hydraulic cylinder, or electric actuator, without any particular limitation.

[0054] The upper push flag 330 and the lower push flag 350, as well as the related drive mechanism, can be arranged in two columns at both ends of the page width according to the first support rod 310 and the second support rod 320, and then connected to the first support rod 310 and the second support rod 320 respectively, so as to adjust simultaneously with the first support rod 310 and the second support rod 320 to ensure that the upper push flag 330 or the lower push flag 350 is aligned with the page.

[0055] In one specific embodiment of this utility model, the flag-pushing assembly 300 further includes: The delivery conveyor belt is located between the first support rod 310 and the second support rod 320, and the working surface height of the delivery conveyor belt corresponds to the conveying surface height of the book pages on the first support rod 310 and the second support rod 320.

[0056] Specifically, the working surface height of the delivery conveyor belt corresponds to the conveying surface height of the book pages on the first support rod 310 and the second support rod 320. The working surface height of the delivery conveyor belt is the same as or slightly higher than the working surface height of both the first support rod 310 and the second support rod 320.

[0057] In this invention, by setting up a delivery conveyor belt, when the book pages are pushed on the first support rod 310 and the second support rod 320 by the bottom push flag 350 or the top push flag 330, the working surface of the delivery conveyor belt is level with or slightly higher than the bottom surface of the book pages. After the book pages are pushed to the appropriate position, the bottom surface of the book pages comes into contact with the working surface of the delivery conveyor belt, and the delivery conveyor belt carries the book pages away through friction. After setting a high conveying speed, the delivery conveyor belt can quickly deliver the book pages.

[0058] In setting up the delivery conveyor belt, in a row of bottom push flags 350 or top push flags 330 corresponding to the first support rod 310 or the second support rod 320, the interval between two adjacent bottom push flags 350 or top push flags 330 is set according to the required delivery effect, so as to ensure that the book pages can be delivered through the delivery conveyor belt without obstruction, so as to be directly delivered to other processing mechanisms.

[0059] In one specific embodiment of this utility model, the flag-pushing assembly 300 further includes: The number of adjusting blocks 360 corresponds to the number of the first support rod 310 and the second support rod 320. The first support rod 310 and the second support rod 320 are respectively set on the two adjusting blocks 360. The number of adjusting screws 370 corresponds to the number of adjusting blocks 360, and the adjusting blocks 360 are threadedly engaged with the adjusting screws 370.

[0060] The adjusting screw 370 can be driven electrically, manually, or both simultaneously, as long as the adjustment accuracy is guaranteed.

[0061] In this invention, by setting a threaded adjusting block 360 and an adjusting screw 370, and by setting the first support rod 310 and the second support rod 320 on the corresponding adjusting block 360, the position of the adjusting block 360 can be controlled by driving the adjusting screw 370 to rotate, so as to control the gap width between the first support rod 310 and the second support rod 320. The first support rod 310 and the second support rod 320 are set in accordance with the width of the book pages, which helps to adapt to the conveying of book pages of different sizes and ensures the conveying effect.

[0062] In one specific embodiment of this utility model, the flag-pushing assembly 300 further includes: The third support rod 600 is located between the first support rod 310 and the second support rod 320, with its extension direction corresponding to the page conveying direction and its height corresponding to the working surfaces of the first support rod 310 and the second support rod 320. The third support rod adjustment mechanism 610 is used to adjust the position of the third support rod 600.

[0063] The third support rod 600 can be located in the middle of the space between the first support rod 310 and the second support rod 320, or it can be located elsewhere. The design can be adjusted according to the shape of the accessories that may be involved on the bottom surface of the book page. The number of third support rods 600 can be adjusted according to actual production needs. Specifically, it can be one, two, or three, as long as it can ensure that it can bear the load and does not adversely affect the conveying effect.

[0064] Specifically, the third support rod adjustment mechanism 610 may include a slide rail and a slider that are slidably connected. The guide rail can be set along the page conveying direction or at an angle to the page conveying direction. The third support rod 600 can be slidably connected to the slider, and the sliding direction of the third support rod 600 on the slider is not parallel to the sliding direction of the slider on the slide rail. With this setting, the height and position of the support rod can be easily adjusted to adapt to the conveying and bearing effect of different pages.

[0065] In this invention, the first support rod 310 and the second support rod 320 are set at both ends of the width direction of the book page according to the width of the book page. There may be a large space between them. By setting the third support rod 600, the book page can be supported to ensure the conveying and feeding effect. The book page is not easy to fall from the gap into the machine, which is conducive to ensuring the long-term working performance of the machine.

[0066] In one specific embodiment of this utility model, the drop-type page delivery structure further includes: The push flag 500 is located on one side of the input end of the conveying gap 110 and is used to abut against the end of the book page away from the conveying gap 110; The push-down flag drive mechanism 510 is used to drive the push-down flag 500 to move along the page conveying direction.

[0067] The drop-type page delivery structure may also include a tray, located on one side of the input end of the conveying gap 110, extending in a direction corresponding to the conveying direction of the pages. A space for the downward push flag 500 to move is provided in the middle of the tray. Limiting parts may be provided on both sides of the page width direction on the tray. By using a tray to support the pages, it is beneficial to ensure that the pages are aligned and enter the conveying gap 110, and also to facilitate a smooth pushing process.

[0068] Specifically, the push-flag drive mechanism 510 may include a chain and a drive sprocket for rotating the chain. The push-flag 500 is mounted on the chain, with the output end of the chain close to the input end of the conveying gap 110. By driving the push-flag 500 to rotate via the chain, the book pages can be cyclically pushed into the conveying gap 110.

[0069] Specifically, the push flag 500 and the chain can be set in two columns corresponding to the two sides of the page width direction, and the two chains are driven by the same drive sprocket.

[0070] In this invention, the book pages need to pass between the conveying roller 100 and the pressure roller 200, which creates some resistance during the feeding process. By setting a push-flag driving mechanism 510, the push-flag 500 is driven to move along the conveying direction of the book pages. The push-flag 500, by abutting against the end of the book page away from the output gap 110, helps to push the book page into the output gap 110. After entering the conveying gap 110, the book page is held by the conveying roller 100 and the pressure roller 200, and is conveyed out by rotation and detached from the push-flag 500, which helps to ensure the alignment accuracy of the book page processing process.

[0071] Specifically, the bottom push flag 500 can also be set on one side of the output end of the output gap 110 to push the pages with a similar effect to the bottom push flag 350.

[0072] In one specific embodiment of this utility model, the drop-type page delivery structure further includes: The page-lifting bar 400 is located on one side of the conveying end of the conveying gap 110, close to the conveying gap 110, and between the page and the conveying roller 100. It separates the page from the conveying roller 100 by abutting against the page.

[0073] In this invention, because the conveyor roller 100 and pressure roller 200 apply pressure to the book pages, the pages may stick to the conveyor roller 100 or pressure roller 200 during output and rotate with it, especially after being glued through the conveyor roller 100. By setting the page-lifting bar 400, the book pages can be separated from the conveyor roller 100 in time when they are sent out of the conveyor gap 110, avoiding continuous sticking. Since the side of the book pages facing the pressure roller 200 is generally not coated with glue, they can be separated in time, and the pusher flag assembly 300 will also receive the book pages in time to ensure the separation effect, which is beneficial to ensuring the accuracy of subsequent processing.

[0074] The drop-type page delivery mechanism of this utility model can be set between the page delivery mechanism and the mounting mechanism. After the glue is transferred through the conveyor roller 100, the page is delivered to the tray of the mounting mechanism.

[0075] The working principle of the drop-type page delivery structure of this utility model is as follows: Adjusting the adjusting screw 370 according to the width of the page, and controlling the position of the adjusting block 360, the positions of the first support rod 310 and the second support rod 320 are controlled in a suitable position to ensure they correspond to the conveying direction of the page. Adjusting the interval width ensures that it can support both ends of the page width direction. By adjusting the sliding position of the slider in the third support rod adjusting mechanism 610 on the slide rail, the sliding height of the third support rod 600 on the slider is adjusted, controlling the support rod to a suitable position, generally flush with the working surfaces of the first support rod 310 and the second support rod 320.

[0076] After preparation, the page is placed on the tray located on one side of the input end of the conveyor gap 110 by the page-laying mechanism. The push flag 500 is set on the chain, and the chain is driven to rotate by the drive sprocket. The push flag 500 contacts and pushes the end of the page away from the conveyor gap 110 until the page is pushed into the conveyor gap 110. After the page enters the conveyor gap 110, the page is rotated out by the counter-rotating conveyor roller 100 and pressure roller 200. At this time, the conveyor roller 100 transfers glue to the page. When the page passes through the conveyor gap 110, the protruding end is abutted by the page-lifting rod 400 and separated from the conveyor roller 100 to prevent it from following. After passing through the conveyor gap 110, the page falls onto the first support rod 310 and the second support rod 320, and is also supported by the third support rod 600 for subsequent conveying.

[0077] When conveying via the pusher flag 330, the second drive mechanism drives the conveyor belt 340 to rotate. The pusher flag 330 is set on the conveyor belt 340. When the conveyor belt 340 runs to one end near the conveying gap 110, it flips downward and descends to the same height as the book page. It contacts and abuts against the end of the book page near the output gap 110 and pushes or drops it. The pusher flag 330 is reset by the conveyor belt 340 and realizes the cyclic pushing action.

[0078] When conveying via the bottom pusher 350, the bottom pusher 350 is driven to move upward by the bottom pusher vertical movement mechanism. The protrusion 351 of the bottom pusher 350 extends out of the working surface of the first support rod 310 and the second support rod 320, and rises to the same height as the book page. The protrusion 351 is driven to move along the conveying direction of the book page by the bottom pusher longitudinal drive mechanism. The protrusion 351 contacts and pushes the book page. After being pushed to the appropriate position or thrown out from the first support rod 310 or the second support rod 320, the bottom pusher 350 is reset to the initial position by the bottom pusher longitudinal movement mechanism and the bottom pusher vertical movement mechanism to realize the cyclic pushing action.

[0079] The drop-type page delivery structure provided in this application is easily adaptable to pages of different sizes, facilitating the delivery of pages after gluing. Pages can be delivered to subsequent processing mechanisms such as laminating mechanisms via the upper push flag 330 or the bottom push flag 350, reducing transfer and adjustment processes. This helps to ensure conveying efficiency while improving docking accuracy and processing efficiency.

[0080] It should be understood that the application of this utility model is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of this utility model.
