Description

Technical Field

DETAILED DESCRIPTION

[0023] To more clearly illustrate the technical solutions in the embodiments of the present invention, the above briefly describes the drawings required for describing the embodiments. Obviously, the drawings described only represent some embodiments of the present invention, not all embodiments. Those skilled in the art can also derive other design solutions and drawings based on these drawings without inventive effort.

[0024] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships mentioned in the text do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the present invention can be combined interchangeably without conflicting with each other.

[0025] The traditional laminating production line uses a manual screw to adjust the width adjustment mechanism 500, which has the problems of low adjustment efficiency and time-consuming manual calibration. The existing equipment lacks the ability to quickly change models and is difficult to adapt to the production needs of products of multiple specifications. In long-distance production lines, due to the complex mechanical linkage structure, the limit plates on both sides are prone to asynchronous displacement, resulting in page positioning deviation.

[0026] To this end, the present invention proposes a laminating production line, referring to Figures 1 to 6, which includes a frame 100 and a page pushing mechanism 200, a width adjusting mechanism 500, a paper discharging mechanism 300 and a glue spraying mechanism 400 all arranged on the frame 100; the page pushing mechanism 200 is used to push the pages to move; the paper discharging mechanism 300 is used to transfer the pages to the page pushing mechanism 200; the glue spraying mechanism 400, the paper discharging mechanism 300 is arranged downstream of the glue spraying mechanism 400, and the glue spraying mechanism 400 is used to glue the pages; the width adjusting mechanism 500 is used to limit the lateral position of the pages, and the width adjusting mechanism 500 includes a first The limiting member 510, the second limiting member 520, and the transmission shaft 530, the drive motor 540 and multiple width adjustment components 550 are all arranged on the frame 100. The drive motor 540 drives the transmission shaft 530 to rotate, and all the width adjustment components 550 are transmission connected to the transmission shaft 530. The first limiting member 510 and the second limiting member 520 are arranged on the width adjustment component 550, and the width adjustment component 550 is used to drive the first limiting member 510 and the second limiting member 520 to move along the width direction of the frame 100.

[0027] The page pushing mechanism 200 pushes the pages to move, ensuring that the pages reach each workstation smoothly; the paper discharging mechanism 300 transfers the pages to the page pushing mechanism 200, ensuring that the pages enter the processing flow in an orderly manner; the glue spraying mechanism 400 glues the pages to provide the necessary glue for laminating the pages; the first limiter 510 and the second limiter 520 limit the lateral position of the pages to ensure that the pages are accurately positioned in the width direction; the transmission shaft 530 rotates under the drive of the drive motor 540, transmitting power to multiple width adjustment components 550, so that each width adjustment component 550 can work together; the width adjustment component 550 is connected to the transmission shaft 530, driving the first limiter 510 and the second limiter 520 to move along the width direction of the frame 100, thereby adjusting the limit width to meet the limit requirements of pages of different specifications. When the production line is very long, multiple width adjustment components 550 are linked by a transmission shaft 530 to drive the first limit member 510 and the second limit member 520 to adjust the width limit synchronously, avoiding asynchronous displacement of the limit plates on both sides and ensuring accurate positioning of the pages in the horizontal position; at the same time, it makes adjusting the width limit more convenient and efficient, can quickly adapt to the production needs of products of different specifications, and reduces the time cost of manual calibration.

[0028] In actual production applications, multiple paper discharge mechanisms 300 and multiple glue spraying mechanisms 400 can be set, and the paper discharge mechanisms 300 and the glue spraying mechanisms 400 are sequentially spaced from upstream to downstream along the direction of book page conveyance; the book pages to be laminated are placed on the paper discharge mechanism 300, and the paper discharge mechanism 300 transfers the book pages to the page pushing mechanism 200. The page pushing mechanism 200 is driven by a driving device such as a motor to smoothly push the book pages to pass through the width adjustment mechanism 500 in sequence; when it is necessary to change to produce pages of different specifications, the driving motor 540 is controlled to start and stop. The transmission shaft 530 is driven to rotate according to parameters such as stop and rotation direction, thereby driving the width adjustment component 550 to move the first limit member 510 and the second limit member 520 to the appropriate width position, thereby accurately limiting the position of the book pages of the new specification; when the book page moves to the work station where the glue spraying mechanism 400 is located, the glue spraying mechanism 400 glues the book page according to the preset parameters; then the page moves to the work station of the second paper discharge mechanism 300, and the above operation is repeated to finally complete the book page mounting process; subsequently, subsequent processes such as pressing and collecting can be set according to actual needs to process the mounted book pages.

[0029] It should be noted that the specific structures and working principles of the page pushing mechanism 200, the paper discharging mechanism 300 and the glue spraying mechanism 400 are prior art and will not be described in detail here.

[0030] The transmission shaft 530 may deviate during prolonged operation or when subjected to external interference. Therefore, in one embodiment, the width adjustment mechanism 500 further includes at least two support seats 560, each of which is disposed on the frame 100. Each support seat 560 is provided with a first bearing 561, and the transmission shaft 530 is inserted into the interior of the first bearing 561. The transmission shaft 530 is fixedly connected to the inner ring of the first bearing 561 via a pre-tightening nut. The first bearing 561 can reduce the friction experienced by the transmission shaft 530 during rotation, while also providing a certain radial positioning function for the transmission shaft 530, thereby assisting it in maintaining a correct rotational posture. The pre-tightening nut is fixedly connected to the inner ring of the first bearing 561. By applying an appropriate pre-tightening force, the transmission shaft 530 can be firmly fixed to the inner ring of the first bearing 561, thereby preventing the transmission shaft 530 from axial movement during operation and ensuring a relatively stable position of the transmission shaft 530.

[0031] The traditional width adjustment method may be difficult to accurately ensure that the first limit member 510 and the second limit member 520 move synchronously, and it is easy for the two sides to adjust asynchronously, thereby affecting the accurate positioning of the book pages and adversely affecting the production quality. Therefore, in one embodiment, each of the width adjustment components 550 includes a first shaft sleeve 551, a second shaft sleeve 552 and a limit shaft 553, the first shaft sleeve 551 is fixedly connected to the first limit member 510, the second shaft sleeve 552 is fixedly connected to the second limit member 520, the limit shaft 553 and the frame 100 are relatively rotatable and are arranged on the frame 100, the limit shaft 553 is provided with a first thread segment and a second thread segment, the thread rotation directions of the first thread segment and the second thread segment are opposite, the first shaft sleeve 551 is threadedly connected to the first thread segment, and the second shaft sleeve 552 is threadedly connected to the second thread segment. When the spacing between the first and second limiting members 510, 520 needs to be adjusted to accommodate pages of different widths, an external force causes the limiting shaft 553 to begin rotating. Since the first and second threaded segments on the limiting shaft 553 have opposite threaded directions, and the first sleeve 551 is threadedly connected to the first threaded segment, and the second sleeve 552 is threadedly connected to the second threaded segment, according to the characteristics of the threaded transmission, when the limiting shaft 553 rotates, the first sleeve 551 moves in one direction along the first threaded segment, while the second sleeve 552 moves in the opposite direction along the second threaded segment, causing the first and second limiting members 510, 520 to move toward or away from each other synchronously. In this way, the spacing between the first and second limiting members 510, 520 can be precisely adjusted to achieve positional adaptation for pages of different widths. This allows for quick and precise adjustment of the spacing between the two, improving adaptability to pages of different widths and better meeting the needs of producing products with multiple specifications.

[0032] During the forward and reverse rotation of the limiting shaft 553, axial movement is likely to occur due to factors such as the axial force generated by the threaded transmission. Therefore, in one embodiment, a second bearing 554 is provided at both ends of the limiting shaft 553, the outer ring of the second bearing 554 is fixedly connected to the frame 100, and the inner ring of the second bearing 554 is fixedly connected to the limiting shaft 553. During the operation of the width adjustment component 550, when the limiting shaft 553 needs to rotate forward or reverse to adjust the distance between the first limiting member 510 and the second limiting member 520, the limiting shaft 553 will be subjected to an axial force, which will be transmitted to the bearing. The second bearing 554 is configured as a bidirectional thrust bearing to prevent the limiting shaft 553 from moving in the axial direction, so that the limiting shaft 553 can only rotate stably around its own axis, ensuring a smoother and more efficient production process, improving production efficiency and product quality, and extending the service life of the equipment.

[0033] The multiple width adjustment mechanisms 500 require multiple power sources along the width direction of the frame 100 to drive the limiting shaft 553 to rotate. Therefore, in one embodiment, the width adjustment mechanism 500 further includes multiple second bevel gears 555 and multiple first bevel gears 531. All of the first bevel gears 531 are coaxially arranged with the transmission shaft 530 for transmission, and the second bevel gears 555 are coaxially arranged with the limiting shaft 553 for transmission in a one-to-one correspondence. The first bevel gears 531 are meshed with the second bevel gears 555 in a one-to-one correspondence. When the width adjustment mechanism 500 of the laminating production line is in operation, the drive motor 540 drives the transmission shaft 530 to rotate, and the multiple first bevel gears 531 provided on the transmission shaft 530 rotate along with the transmission shaft 530; the second bevel gears 555 provided on the limiting shaft 553 mesh with the corresponding first bevel gears 531 one by one, and the first bevel gears 531 transmit power in a vertical direction to the second bevel gears 555 meshed with it. After receiving the power, the second bevel gears 555 drive the limiting shaft 553 coaxial with it to rotate, thereby driving the first limit member 510 and the second limit member 520 to move in the width direction of the frame 100, thereby achieving the limit adjustment of the horizontal position of the book page. The layout of the entire transmission system is more reasonable and compact, fully utilizing space, avoiding complex transmission path design, and improving the efficiency and accuracy of power transmission.

[0034] During the actual width adjustment process, the sleeve may experience radial offset due to various factors, which may cause the limiter connected to it to fail to move along the expected linear trajectory, affecting the accurate positioning of the horizontal position of the book page and reducing production quality. Therefore, in one embodiment, the width adjustment assembly 550 also includes a guide rod 556, which is arranged on the frame 100 parallel to the limit shaft 553. The first limiter 510 and the second limiter 520 are both provided with guide holes that slide with the guide rod 556. When the width adjustment assembly 550 is in operation, the limit shaft 553 rotates under power drive. Based on the threaded connection between the limit shaft 553 and the first sleeve 551 and the second sleeve 552, the sleeve begins to move. The guide rod 556, through cooperation with the guide hole, constrains the limiter, limiting the radial movement of the limiter so that the limiter can only slide along the axial direction of the guide rod 556. By setting a guide rod 556 parallel to the limit shaft 553 and making the limit member slide with it through the guide hole, the radial offset in the width adjustment process is effectively eliminated, and the linear accuracy of the limit member's moving trajectory is improved, so that the first limit member 510 and the second limit member 520 can adjust the spacing more accurately and stably, which helps to ensure the consistency of product quality and reduce the defective rate caused by inaccurate limiting.

[0035] The traditional integrated transmission shaft 530 structure can present numerous inconveniences during installation, maintenance, and adaptability to varying production scenarios. For example, the installation process requires extremely high overall precision, and if a component develops a problem, repair or replacement becomes cumbersome. Therefore, in one embodiment, the transmission shaft 530 includes multiple shafts 532 and multiple couplings 533 . The couplings 533 are positioned between each pair of adjacent shafts 532 to ensure coaxial transmission of all shafts 532 . During installation, each shaft body 532 can be installed and positioned separately and connected by means of a coupling 533, which reduces the requirements for the installation site and installation equipment, improves the convenience and efficiency of installation, and can easily complete the assembly of the transmission shaft 530 even in a long-distance production line; the transmission shaft 530 adopts a combination structure of multiple shaft bodies 532 and multiple couplings 533. When the first shaft body 532 rotates, power is transmitted to the adjacent second shaft body 532 through the coupling 533. The coupling 533 relies on its own connection and compensation functions to make the two shaft bodies 532 rotate coaxially as a whole. Even if there are certain axial and radial deviations between the two shaft bodies 532 during installation, the coupling 533 can ensure smooth transmission of power.

[0036] After the book pages have passed through the previous process, position deviation may occur. Especially during the long-distance production line operation, this deviation may be more obvious. If they directly enter the glue spraying mechanism 400, the glue spraying position will be inaccurate, affecting the mounting quality of the book pages. Therefore, in one embodiment, the mounting production line further includes a limiting mechanism 600, which is arranged upstream of the glue spraying mechanism 400. The limiting mechanism 600 includes a first mounting plate 610, a limiting guide rail 620, a limiting block 630 and a limiting motor 640. The first mounting plate 610 is fixedly connected to the first limiting member 510, the limiting guide rail 620 is arranged on the first mounting plate 610, the limiting motor 640 is slidably connected to the limiting guide rail 620, the limiting block 630 is arranged at the output end of the limiting motor 640, and the limiting motor 640 is used to drive the limiting block 630 to move up and down along the limiting guide rail 620. During the operation of the laminating production line, when the book page is about to enter the glue spraying mechanism 400, the limit motor 640 slides to the appropriate position along the limit guide rail 620, and the limit motor 640 starts, driving the limit block 630 at its output end to start moving downward. The edge of the book page moving on the page pushing mechanism 200 is against the limit block 630, so that the edge of the book page is aligned, ensuring that the subsequent gluing operation of the glue spraying mechanism 400 can be accurately performed on the correct position of the book page, thereby improving the quality and effect of laminating.

[0037] Aligning the book pages solely by the limiting mechanism 600 may have certain limitations, because the book pages may be uneven in multiple directions during the previous circulation process, and it is difficult to fully ensure the overall neatness of the book pages by aligning the book pages solely by the limiting mechanism 600. Therefore, in one embodiment, the laminating production line further includes an alignment mechanism 700, the limiting mechanism 600 is arranged upstream of the glue spraying mechanism 400, the alignment mechanism 700 includes an alignment block 730, an alignment rack 740, an alignment gear 750, a buffer 710 and an alignment motor 720, the alignment motor 720 is arranged on the first limiting member 510, the alignment rack 740 is arranged on the output end of the alignment motor 720, the buffer 710 is arranged on the first limiting member 510, one end of the buffer 710 is used to resist the alignment rack 740, the alignment block 730 is rotatably connected to the first limiting member 510, the alignment gear 750 is arranged at one end of the alignment block 730, the alignment gear 750 and the alignment block 730 are coaxially transmitted, and the alignment gear 750 is meshed with the alignment rack 740. When the book pages are aligned after passing through the limiting mechanism 600, the aligning motor 720 is started, and the aligning rack 740 at its output end begins to move linearly under the drive of the motor; during the movement of the aligning rack 740, one end is against the buffer 710, and the buffer 710 plays a buffering role to stabilize the movement of the rack; the aligning rack 740 is meshed with the aligning gear 750 on the aligning block 730, and as the aligning rack 740 moves linearly, the aligning gear 750 is driven to rotate; since the aligning gear 750 and the aligning block 730 are coaxially driven, the aligning block 730 rotates around the connection point with the first limiting member 510, and when the aligning block 730 rotates, it generates a slapping force on the edge of the book page away from the limiting mechanism 600. The limiting mechanism 600 and the aligning mechanism 700 simultaneously align the book pages, so that the pages can reach a better alignment state before entering the glue spraying mechanism 400, ensuring the smooth progress and quality of the glue spraying and subsequent mounting processes.

[0038] During the movement of the book pages, they may become loose and uneven. This can lead to uneven glue application and loose mounting during the gluing and laminating process, resulting in poor mounting quality and affecting the quality of the final product. Therefore, in one embodiment, the laminating production line further includes a pre-pressing bar 800 , which is disposed on the first stopper 510 and is arranged obliquely downward in the direction of travel of the book pages. The pre-pressing bar 800 is used to press the book pages. When the page pushing mechanism 200 pushes the book pages to move along the length direction of the frame 100, the book pages will pass through the pre-pressing strip 800 set on the first limit member 510; since the pre-pressing strip 800 is set to be inclined downward along the forward direction of the book pages, the book pages will contact the pre-pressing strip 800 during the movement, and the pre-pressing strip 800 will generate a downward pressure on the book pages; under this pressure and the guidance of the inclined structure of the pre-pressing strip 800, the book pages will gradually change their own state, and the unevenness, warping and other conditions that may have existed will be improved. The pages will be initially attached together along the inclined direction of the pre-pressing strip 800, making the relative positions between the book pages tighter and more regular, creating favorable conditions for the subsequent glue spraying mechanism 400 to accurately apply glue on the book pages and better realize the mounting operation.
