[0019] In the description of this utility model, unless otherwise explicitly defined, terms such as "set," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0020] The following is combined Figures 1 to 4 The embodiments of this utility model are described below.

[0021] This application provides a cardboard book processing unit, which includes: rack 100, on which are provided: The blackboard conveyor line 200 is provided with an inner page processing device 300, a paper separation processing device 400 and an accessory feeding device 500 in sequence along the conveying direction of the blackboard conveyor line 200. The inner page processing device 300 includes an inner page feeding mechanism 310 and a first gluing mechanism 320. The inner page feeding mechanism 310 is used to transfer the folded inner pages to the first gluing mechanism 320. The first gluing mechanism 320 is used to apply glue to the inner pages and transfer the glued inner pages to the blackboard conveyor line 200. The paper separation processing device 400 includes a paper separation feeding mechanism 410 and a second gluing mechanism 420. The paper separation feeding mechanism 410 is used to transfer stacked paper separations to the second gluing mechanism 420. The second gluing mechanism 420 is used to glue the paper separations and transfer the glued paper separations to the inner pages of the blackboard conveyor line 200. The accessory loading device 500 is used to transfer accessories onto the glued separator paper on the blackboard conveyor line 200.

[0022] In this way, the inner page feeding mechanism 310 transfers the folded inner pages to the first gluing mechanism 320, and after partial gluing, they are transferred to the blackboard conveyor line 200. The spacer feeding mechanism 410 transfers the spacers to the second gluing mechanism 420, and after gluing, they cover the surface of the inner pages on the conveyor line. Then, the accessory feeding device 500 transfers the accessories to the surface of the spacers, completing the sequential mounting of the inner pages, spacers, and accessories. The processing devices for inner pages, spacers, and accessories are connected in series along the conveyor line. The mechanical structure realizes automatic feeding, gluing, transfer, and stacking, replacing the manual mounting process and forming a continuous production line.

[0023] Therefore, by setting up an inner page processing device 300, a paper separating device 400, and an accessory processing device on the blackboard conveyor line 200, the sequential mounting and continuous assembly production of the blackboard inner pages, paper separating devices, and accessories are realized in a mechanized manner, thereby greatly improving production efficiency, effectively reducing assembly errors that are easily caused by manual operation, and improving product quality.

[0024] In some embodiments, the inner page feeding mechanism 310 includes a lower belt assembly 311, an upper belt assembly 312, and an angle assembly 313. The lower belt assembly 311 includes a lower paper clamping belt that swings up and down, and the upper belt assembly 312 includes an upper paper clamping belt that swings up and down. A clamping seam is formed between the lower and upper paper clamping belts for clamping the paperboard pages. The inner pages are generally without holes. The clamping force of the upper and lower belts can achieve stable feeding of the inner pages and avoid slippage or paper jams. The angle assembly 313 is used to adjust and lock the swing angle of the lower and upper paper clamping belts. The angle assembly can change the height of the output end to adapt to the stacking requirements of inner pages with different thicknesses or layers.

[0025] The lower belt assembly also includes a lower belt connecting arm, a first lower rotating shaft, and a second lower rotating shaft. One end of the lower belt connecting arm is hinged to the frame of the inner page feeding mechanism, and the other end is connected to the second lower rotating shaft. The first lower rotating shaft is rotatably mounted on the frame of the inner page feeding mechanism, and the two sides of the lower paper clamping belt wrap around the first and second lower rotating shafts. The upper belt assembly also includes a first upper rotating shaft and a second upper rotating shaft. The first upper rotating shaft is mounted on the frame of the inner page feeding mechanism, and the second upper rotating shaft is mounted on the lower belt connecting arm. The two sides of the lower paper clamping belt wrap around the first and second lower rotating shafts. Both the second lower rotating shaft and the second upper rotating shaft are mounted on the lower belt connecting arm. When the lower belt connecting arm is swung, the second lower rotating shaft and the second upper rotating shaft are simultaneously moved to change their height positions, thereby adjusting the exit height of the page clamping seam. This allows for flexible adaptation to the height requirements of different conveyor line positions and conveniently meets the height adjustment needs of the paper clamping and feeding structure.

[0026] Optionally, the included angle assembly includes a first swing arm hinged to the frame of the inner page feeding mechanism, a connecting shaft mounted on the lower belt connecting arm, a second swing arm hinged to the connecting shaft, and a locking structure. The first and second swing arms are slidably connected, and the locking structure is used to lock the first and second swing arms. Since the second swing arm and the first swing arm are respectively connected to the lower belt connecting arm and the frame of the inner page feeding mechanism, when the two slide relative to each other, the distance between the connecting shaft and the frame can be changed, thereby adjusting the position of the lower belt connecting arm, driving the second upper rotating shaft and the second lower rotating shaft to move synchronously, ultimately achieving the adjustment of the position of the lower belt connecting arm.

[0027] Therefore, the inner page feeding mechanism 310 forms a page seam by configuring the lower belt assembly 311 and the upper belt assembly 312, and quickly feeds out the cardboard in a clamping manner. It is also equipped with an angle assembly 313, which changes the angle of the lower and upper paper clamping belts, and can output the cardboard pages that have passed through the page seam to different height positions.

[0028] In some embodiments, the first gluing mechanism 320 includes a dispensing component 321, a pushing component 322, a gluing component 323, and an output component 324 arranged sequentially and connected to each other; the dispensing component is used to transfer the inner pages one by one to the pushing component 322; the pushing component 322 is used to push the flat inner pages to the gluing component 323, and the gluing component 323 is used to transfer glue to a local area of ​​the inner pages; the output component 324 is used to transfer the glued inner pages to the blackboard output line.

[0029] Specifically, the feeding component 321 conveys the inner pages one by one to the pushing component 322. At this time, the inner pages are horizontally unfolded. Then, the pusher on the pushing component 322 pushes the inner pages between the glue application roller and the support roller of the gluing component 323. The local gluing module on the glue application roller locally transfers the glue to the back of the inner page. Then, the glued inner pages are transferred to the conveyor belt of the conveying component. Similarly, the second gluing mechanism 420 can be configured in the same way, and will not be described in detail here.

[0030] In some embodiments, the paper feeding mechanism 410 includes a paper stacking mechanism 411 and a transfer mechanism 412. The paper stacking mechanism 411 includes a paper base 4111 for stacking multiple paper sheets in a front-back direction and at an angle. The paper base 4111 is disposed on the frame 100. The transfer mechanism 412 includes a moving component 4121 and a suction component 4122 disposed above the paper base 4111. The moving component 4121 includes a first guide structure that moves in a front-back direction and a second guide structure that moves in a vertical direction. The first guide structure is convexly connected to the second guide structure. The suction component 4122 is fixed on the second guide structure. For example, the suction component 4122 includes a suction cup; for pre-cut and framed separators, the separators are placed on the separator base 4111, and the separator base 4111 is tilted to stack the separators. The separator sheets usually have holes, which can easily cause paper jams when stacking and feeding. The tilted stacking setting reduces the risk of paper jams; the transfer mechanism 412 grabs the separators through the suction cup suction component 4122, and transfers them to the second gluing mechanism 420 through a first guide structure that moves back and forth and a second guide structure that moves up and down. The second gluing mechanism 420 is the same as the first gluing mechanism 320 in principle, and after partially gluing the separators, they are covered on the inner pages of the conveyor line.

[0031] In some embodiments, the paper-separating stacking mechanism 411 further includes a position adjustment component for adjusting the size of the paper-separating feeding position. The position adjustment component includes a first receiving plate, a second receiving plate, and an adjustment structure. The first receiving plate and the second receiving plate are disposed on the paper-separating base 4111, and a paper-separating groove is formed between the first receiving plate and the second receiving plate. The adjustment structure is used to move the first receiving plate and the second receiving plate away from or closer to each other to change the width of the paper-separating groove.

[0032] The first and second receiving plates form a relatively long paper-separating groove, which meets the needs of multiple processes in the production of the paper-separating groove. Thus, the distance between each of the first and second receiving plates can be adjusted by adjusting the structure, and the width of the paper-separating groove of the entire production line can be adjusted quickly and conveniently.

[0033] In some embodiments, the accessory feeding device 500 includes an accessory stacking mechanism 510, a dispensing mechanism 520, an accessory positioning mechanism 530, and a removal mechanism 540. The dispensing mechanism 520 includes a dispensing drive assembly mounted on the frame 100, a dispensing slide that slides left and right and up and down driven by the dispensing drive assembly, a claw adjusting structure mounted on the dispensing slide, and a dispensing claw mounted on the claw adjusting structure. The dispensing claw grips a single accessory and transfers it to the positioning mechanism. The claw adjusting structure is used to adjust the position of the dispensing claw. The removal mechanism 540 includes a removal drive structure mounted on the frame 100, a removal frame driven by the removal drive structure, a removal gripping adjusting structure mounted on the removal frame, and a removal claw mounted on the removal gripping adjusting structure. The removal gripping adjusting structure is used to adjust the position of the removal claw, and the removal claw is used to remove the accessory from the removal position and transfer the positioned accessory to the paper separator surface.

[0034] Specifically, the parts feeding device 500 is equipped with a storage mechanism, a parts positioning mechanism 530, and a removal mechanism 540, which are used to store, distribute, position, and remove parts, respectively. The storage mechanism is equipped with a claw adjustment structure to adjust the position of the distributing claw, and the removal mechanism 540 is equipped with a removal gripping adjustment structure to adjust the position of the removal claw. The positions of the distributing claw and the removal claw can be adjusted according to different parts in order to output parts.

[0035] In use, the parts can be placed directly on the storage mechanism. In the stored state, the parts are placed close together at an angle of 15-45 degrees, with the tilt direction opposite to the removal mechanism 540. Alternatively, the materials can be laid flat on the storage conveyor belt of the storage mechanism at intervals. After one part is removed by the dispensing claw, the storage conveyor belt on the storage platform starts, causing the materials on the storage platform 11 to move towards the removal claw, so that the removal claw can remove the remaining materials.

[0036] In some embodiments, the accessory feeding device 500 further includes a visual positioning mechanism 550, which includes a correction table, a first lateral movement component, a first longitudinal movement component, and a camera. The correction table is disposed on the whiteboard conveyor line 200. The first lateral movement component is used to drive the correction table to move laterally, and the first longitudinal movement component is used to drive the correction table to move longitudinally. The camera is disposed on the frame 100 and is positioned facing the correction table.

[0037] Specifically, the visual positioning mechanism 550, through the coordinated operation of a camera, a correction table, and first lateral and first longitudinal components, works as follows: after the paper is placed on the correction table, the camera captures images of the table and the paper. Based on the paper's position on the table, the first lateral and first longitudinal components move the correction table to adjust its position, ensuring the paper is accurately moved to the target location for further processing, such as precise positioning when placing accessories. This design ensures accurate positioning in subsequent processes, and the entire mechanism features simple operation and high positioning accuracy.

[0038] In some embodiments, the accessory stacking mechanism includes a base and a stacking assembly, wherein the stacking assembly includes a stacking base plate and a stacking rack for stacking accessories, and the stacking base plate is detachably mounted on the base. The stacking rack and the stacking base plate form an independent stacking module. By simply removing and installing the stacking base plate, stacking racks of different specifications can be quickly replaced, thereby flexibly adapting to various accessories; in addition, rapid replenishment can also be achieved by replacing the stacking rack, improving operational efficiency.

[0039] Furthermore, the accessory feeding device also includes a glue spraying mechanism for spraying glue onto the raw materials.

[0040] This application also provides a paperboard book production line, including a paperboard book processing unit as described in any of the above technical solutions. The paperboard book production line can be equipped with multiple paperboard book processing units, and the inner page processing device, the paper separating device, and the accessory feeding device can be combined to support customized production and meet the manufacturing needs of different paperboard books. Since this paperboard book production line uses the paperboard book processing unit disclosed in the embodiments of this utility model, it possesses the technical advantages of the paperboard book processing unit disclosed in the embodiments of this utility model, which will not be described in detail here.
