[0002] This disclosure claims priority to Chinese patent application No. 202520199616.X, entitled "Paper Sticker", filed on February 8, 2025, with the China National Intellectual Property Administration, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of packaging technology, and more particularly to a paper gluing machine. Background Technology

[0004] After the tiles are processed, they need to be packaged to reduce the chance of breakage and scratches during transportation and storage.

[0005] In related technologies, a paper-adhesive mechanism is embedded in a tile packaging machine. The tile packaging machine includes a paper-adhesive mechanism, a conveying mechanism, and a folding mechanism. The paper-adhesive mechanism glues multiple cardboard sheets together to form a carton board. The conveying mechanism transports the tiles to the carton board at the packaging position. The folding mechanism bends the carton board to form a carton, thereby covering at least four side areas of the tile.

[0006] However, the gluing mechanism's operating speed needs to be adjusted according to the folding mechanism's packaging speed. Since the folding mechanism has many packaging actions, the gluing mechanism has long downtime and low efficiency.

Detailed Implementation

[0077] After the tiles are processed, they need to be packaged to reduce the chance of breakage and scratches during transportation and storage.

[0078] In related technologies, a paper-adhesive mechanism is embedded in a tile packaging machine. The tile packaging machine includes a paper-adhesive mechanism, a conveying mechanism, and a folding mechanism. The paper-adhesive mechanism glues multiple cardboard sheets together to form a cardboard box. The conveying mechanism transports the tiles to the cardboard box at the packaging position. The folding mechanism folds the cardboard box to form a carton, thus covering at least four sides of the tile. However, the operating speed of the paper-adhesive mechanism needs to be adjusted according to the packaging speed of the folding mechanism. Since the folding mechanism involves numerous packaging actions, the paper-adhesive mechanism experiences long downtimes and low efficiency.

[0079] Furthermore, the paper trays of the gluing mechanism are located on both sides of the conveying direction of the packaging production line. The gluing mechanism needs to pick up paper from both sides, taking a total of four pieces of cardboard; then move and glue them to form a rectangular carton. The paper picking mechanism of the gluing mechanism is complex. For example, a robotic arm can be used to pick up the paper. As a result, the gluing mechanism is inefficient.

[0080] In addition, since the adhesive paper structure is embedded in the tile packaging machine, the entire packaging production line needs to be shut down when the adhesive paper machine malfunctions, which affects production efficiency; and the adhesive paper mechanism is located inside the packaging production line, making maintenance inconvenient.

[0081] In view of this, this disclosure provides a paper gluing machine that is set up independently of the ceramic tile packaging machine. Because the paper gluing machine is independent of the folding mechanism of the packaging machine, it is not affected by the packaging cycle time of the packaging machine. The paper gluing machine in this embodiment is used to assemble cardboard boxes with a centrally cut-out section. The gluing machine is used to produce cardboard boxes for packaging ceramic tiles. The machine has paper bins in multiple locations, each with a separate paper-feeding mechanism to retrieve paper from these bins. This simplifies the paper-feeding process. Paper is fed from multiple directions (vertically (Z-axis direction) perpendicular to the plane defined by the first and second directions, and vertically opposite directions) to the gluing position. Four pieces of cardboard are then glued together to form a cardboard box. The machine utilizes step-by-step paper feeding in the first and second directions, as well as rapid horizontal paper feeding, and vertically opposite paper feeding for shorter travel distances, improving gluing efficiency. Furthermore, the rapid paper feeding and gluing position adjustment in multiple directions allows for the combination of cardboard boxes of different sizes, increasing applicability and reducing the paper-feeding travel path. This not only simplifies the paper-feeding mechanism structure but also improves paper feeding speed and gluing efficiency.

[0082] Moreover, paper bins are set up in multiple directions, which can store a large amount of paper, reduce the frequency of paper replenishment, and help reduce labor intensity.

[0083] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0084] First, referring to Figure 1, the unfolded state of the carton formed by the paper gluing machine in the embodiment of this disclosure is described.

[0085] As shown in Figure 1, the cardboard box is a cardboard board 10 when unfolded. The cardboard board 10 is folded up and wrapped around the edge of the tile to form the cardboard box.

[0086] The cardboard board includes two first cardboard 11 and two second cardboard 12, which are glued together and enclosed to form a cardboard board 10 with a rectangular opening.

[0087] The first cardboard 11 and the second cardboard 12 are rectangular, and the two ends of the first cardboard 11 overlap at least partially with the ends of the two second cardboards 12 to form an adhesive area 13. An adhesive, such as glue, is provided in the adhesive area 13 to bond the first cardboard 11 and the second cardboard 12 together and form a cardboard box 10 with a hollow center.

[0088] Referring to Figure 2, this embodiment of the present disclosure provides a paper gluing machine, which is set up independently of the packaging machine, for assembling cardboard boxes with a hollow center. It includes a frame 920, which provides installation positions for the installation of other components. The frame 920 may include multiple transverse beams, multiple longitudinal beams, and multiple vertical beams, which are connected to form a truss structure.

[0089] The adhesive paper machine of this embodiment further includes a control cabinet 910, which is used to control the working state of the adhesive paper machine. The control cabinet 910 may include a cabinet body and control devices disposed within the cabinet body, including but not limited to electrical components such as controllers, memory, and processors.

[0090] Referring again to FIG2, the adhesive paper machine of this embodiment further includes a conveying mechanism 100, which can be mounted on the frame 920. The conveying mechanism 100 is configured to convey the carton board 10 along a first direction.

[0091] Optionally, the conveying mechanism 100 is configured to convey the carton board 10 along the X-axis direction.

[0092] Optionally, the conveying mechanism 100 can be a belt drive structure, which provides smooth and low-noise conveying of cardboard boxes; moreover, the belt drive structure is simple and easy to install and maintain. Furthermore, using a belt drive mechanism to convey cardboard boxes not only allows for long conveying distances but also provides high transmission efficiency, thereby improving the processing efficiency of the gluing machine.

[0093] Optionally, the conveying mechanism 100 includes a conveyor belt, a drive motor, a drive pulley, and a driven pulley. The drive pulley and the driven pulley are spaced apart along a first direction. The conveyor belt is wound around the drive pulley and the driven pulley. The drive motor drives the drive pulley to rotate, thereby causing the portion of the conveyor belt above the pulley to move along the first direction. The conveyor belt receives cardboard boxes and conveys the cardboard boxes out of the gluing machine along the first direction.

[0094] The drive motor can be mounted on the frame 920. The driving pulley and driven pulley are rotatably mounted on the frame 920 to ensure the stability of the conveying mechanism 100 structure.

[0095] The gluing machine of this disclosure also includes a paper bin for storing cardboard for assembling carton boards.

[0096] There can be two paper bins, which are used to hold the first paperboard and the second paperboard respectively. One paper bin can be arranged on one side of the conveying mechanism 100 along the first direction, and the other paper bin can be arranged on one side of the conveying mechanism 100 along the second direction.

[0097] There can be four paper bins, which are arranged in four directions of the conveying mechanism 100. Specifically, two paper bins are arranged on both sides of the conveying mechanism 100 along the first direction and are used to hold the first paperboard; two paper bins are arranged on both sides of the conveying mechanism 100 along the second direction and are used to hold the second paperboard.

[0098] The second direction intersects the first direction; for example, the second direction is perpendicular to the first direction. Referring to Figure 2, the first direction can be the X-axis direction in Figure 2, and the second direction can be the Y-axis direction in Figure 2.

[0099] Optionally, the adhesive paper machine includes a first paper tray 200, which is configured to receive a first paperboard.

[0100] Optionally, two first paper bins 200 are provided, with the two first paper bins 200 respectively located on both sides of the conveying mechanism 100 along the second direction. Both first paper bins 200 are located above the conveying mechanism 100.

[0101] The top of the first paper tray 200 can form a first paper dispensing port, which facilitates paper dispensing from the top of the first paper tray 200. The first paper dispensing port can also serve as a first paper feeding port, used to replenish paper from the top of the first paper tray 200, thereby realizing paper dispensing from top to bottom.

[0102] Alternatively, a first paper dispensing port can be formed at the bottom of the first paper tray 200 to facilitate paper dispensing from the bottom of the first paper tray 200.

[0103] The top of the first paper tray 200 can form a first paper feeding port, which facilitates paper replenishment from the top of the first paper tray 200. With this configuration, paper replenishment from the top of the first paper tray 200 does not affect paper retrieval from the bottom of the first paper tray 200; that is, paper replenishment can be carried out without stopping the gluing machine, and paper replenishment does not affect the operation of the gluing machine, which helps to improve the working efficiency of the gluing machine.

[0104] The adhesive press may also include a second paper tray 300, which is configured to receive a second paperboard.

[0105] Optionally, two second paper bins 300 may be provided, with the two second paper bins 300 respectively located on both sides of the conveying mechanism 100 along the first direction; the two second paper bins 300 are located above the conveying mechanism 100.

[0106] The top of the second paper tray 300 can form a second paper dispensing port, which facilitates paper dispensing from the top of the second paper tray 300. The second paper dispensing port can also serve as a second paper feeding port for replenishing paper from the top of the second paper tray 300, thereby realizing paper dispensing from top to bottom.

[0107] Alternatively, a second paper dispensing port can be formed at the bottom of the second paper compartment 300 to facilitate paper dispensing from the bottom of the second paper compartment 300.

[0108] The top of the second paper tray 300 can form a second paper feeding port, facilitating paper replenishment from the top of the second paper tray 300. With this configuration, replenishing paper from the top of the second paper tray 300 does not affect paper retrieval from the bottom of the second paper tray 300; that is, paper replenishment can be performed without stopping the gluing machine, and paper replenishment does not affect the operation of the gluing machine, which helps to improve the working efficiency of the gluing machine.

[0109] The paper gluing machine of this embodiment stores four pieces of cardboard for a carton by setting two first paper bins 200 and two second paper bins 300. Paper is taken from the four paper bins respectively, which can realize the assembly of the carton. This simplifies the structure of the paper taking mechanism, thereby simplifying the action and path of the paper taking mechanism, and thus improving the assembly efficiency of the carton.

[0110] Optionally, referring to Figure 3, multiple first paper bins 200 located on the same side of the conveying mechanism 100 can be provided, and the multiple first paper bins 200 located on the same side of the conveying mechanism 100 are arranged sequentially along the second direction (corresponding to the Y-axis direction in the figure).

[0111] Optionally, a plurality of first paper trays 200 are provided on the side of the conveying mechanism 100 facing the positive Y-axis, and the plurality of first paper trays 200 are arranged sequentially along the second direction; for example, two first paper trays 200 are provided on the side of the conveying mechanism 100 facing the positive Y-axis, paper is taken from the first paper tray 200 closer to the conveying mechanism 100, and the other first paper tray 200 serves as a spare paper tray. And / or, a plurality of first paper trays 200 are provided on the side of the conveying mechanism 100 facing the negative Y-axis, and the plurality of first paper trays 200 are arranged sequentially along the second direction. The number of first paper trays 200 on both sides of the conveying mechanism 100 along the Y-axis direction can be the same or different. For example, two first paper trays 200 are provided on the side of the conveying mechanism 100 facing the negative Y-axis, paper is taken from the first paper tray 200 closer to the conveying mechanism 100, and the other first paper tray 200 serves as a spare paper tray.

[0112] This embodiment of the invention increases the paper storage space, reduces the frequency of paper replenishment, and lowers labor intensity by setting multiple first paper bins 200 on the same side of the conveying mechanism 100.

[0113] Optionally, referring to Figure 5, multiple second paper bins 300 are provided on the same side of the conveying mechanism 100, and the multiple second paper bins 300 on the same side of the conveying mechanism 100 are arranged sequentially along the first direction (corresponding to the X-axis direction in the figure).

[0114] Optionally, a plurality of second paper trays 300 are provided on the side of the conveying mechanism 100 facing the positive X-axis, and the plurality of second paper trays 300 are arranged sequentially along the first direction X; for example, two second paper trays 300 are provided on the side of the conveying mechanism 100 facing the positive X-axis, paper is taken from the second paper tray 300 closer to the conveying mechanism 100, and the other second paper tray 300 serves as a spare paper tray. And / or, a plurality of second paper trays 300 are provided on the side of the conveying mechanism 100 facing the negative X-axis, and the plurality of second paper trays 300 are arranged sequentially along the first direction. The number of second paper trays 300 on both sides of the conveying mechanism 100 along the X-axis can be the same or different. For example, two second paper trays 300 are provided on the side of the conveying mechanism 100 facing the negative X-axis, paper is taken from the second paper tray 300 closer to the conveying mechanism 100, and the other second paper tray 300 serves as a spare paper tray.

[0115] This embodiment of the invention increases the paper storage space, reduces the frequency of paper replenishment, and lowers labor intensity by providing multiple second paper bins 300 on the same side of the conveying mechanism 100.

[0116] Typically, tiles come in various sizes and require packaging with cardboard boxes of different sizes. For this purpose, at least one of the first and second cardboard boxes needs to be of different sizes.

[0117] Optionally, at least one of the first paper tray 200 and the second paper tray 300 is an adjustable paper tray, which is configured to be adjustable in at least one of its dimensions in a first direction and its dimensions in a second direction to accommodate paperboard of different sizes.

[0118] Optionally, both the first paper tray 200 and the second paper tray 300 can have their length and width dimensions adjusted to accommodate different sizes of cardboard. Referring to the orientation in the accompanying drawings, the dimensions of both the first paper tray 200 and the second paper tray 300 are adjustable along both the first and second directions. The following description uses the second paper tray 300 as an example to illustrate the specific structure by which the first paper tray 200 and the second paper tray 300 achieve dimensional adjustment.

[0119] Referring to Figures 2 and 4, optionally, the second paper compartment 300 includes a first adjusting mechanism 330, a second adjusting mechanism 340, two first paper guides 310, and two second paper guides 320.

[0120] Two first paper stoppers 310 are spaced apart along a first direction, and at least one of the two first paper stoppers 310 is connected to a first adjustment mechanism 330 to adjust the spacing between the two first paper stoppers 310 along the first direction.

[0121] Optionally, the first paper stop 310 includes two limiting posts 311 spaced apart along the first direction. Thus, the two first paper stop 310s have four limiting posts 311, which helps to limit the insertion of the second cardboard 12 and reduces the possibility of the cardboard board 10 being misaligned due to the second cardboard 12 being skewed.

[0122] The first adjustment mechanism 330 is electrically connected to the control cabinet 910. Under the action of the control cabinet 910, the first adjustment mechanism 330 is configured to drive the first paper stop 310 to move along the second direction, thereby adjusting the size of the second paper tray 300 along the second direction (corresponding to the Y-axis direction in Figure 3).

[0123] Optionally, one of the first paper stoppers 310 can be fixed in place, while the other first paper stopper 310 is connected to the output end of the first adjustment mechanism 330 and moves along the second direction under the drive of the first adjustment mechanism 330, thereby adjusting the size of the two first paper stoppers 310 along the second direction. This configuration makes the structure of the first adjustment mechanism 330 simple and easy to maintain.

[0124] Optionally, the first adjusting mechanism 330 can be connected to two first paper stoppers 310 simultaneously, and the first adjusting mechanism 330 is configured to drive the two first paper stoppers 310 to move towards each other or away from each other along the second direction, thereby adjusting the size of the two first paper stoppers 310 along the second direction. This configuration allows for rapid size adjustment between the two first paper stoppers 310.

[0125] Optionally, the first adjustment mechanism 330 may include a linear actuator such as a cylinder or a hydraulic cylinder, the linear actuator being fixed on the frame 920; the output end of the linear actuator is connected to the first paper stop 310, and the linear actuator drives the first paper stop 310 to move along the second direction.

[0126] Optionally, the first adjusting mechanism 330 may include a first adjusting motor and a first transmission component, the first transmission component being configured to convert the rotation of the first adjusting motor into linear movement along a second direction. For example, the first transmission component may include a gear and a rack; another example is that the first transmission component may include a lead screw and a nut; yet another example is that the first transmission component may be a belt drive component.

[0127] Optionally, the first adjusting mechanism 330 includes a first adjusting motor, a first lead screw, a first nut, a second lead screw, and a second nut, wherein the first adjusting motor is fixed to the frame 920. The first adjusting motor may be located on the side of one of the first paper stoppers 310 opposite to the other first paper stopper 310. The first adjusting motor is connected to the first lead screw and drives the first lead screw to rotate. The first lead screw extends along a second direction. The first nut is fixedly connected to one of the first paper stoppers 310 and is threadedly connected to the first lead screw. When the first adjusting motor drives the first lead screw to rotate, the first paper stopper 310 is moved along the second direction via the first nut. The second lead screw is connected to the first lead screw, for example, the second lead screw is connected to the first lead screw via a coupling. The second lead screw is threadedly connected to the second nut, and the second nut is fixedly connected to the other first paper stopper 310. The thread direction of the second lead screw is different from that of the first lead screw. Thus, when the first adjusting motor drives the second lead screw to rotate through the first lead screw, the two first paper stoppers 310 are driven to move towards each other or away from each other in the second direction through the first nut and the second nut.

[0128] Two second paper stoppers 320 are spaced apart along a first direction, and at least one of the two second paper stoppers 320 is connected to a second adjustment mechanism 340 to adjust the spacing between the two second paper stoppers 320 along the first direction.

[0129] The second adjustment mechanism 340 is electrically connected to the control cabinet 910. Under the action of the control cabinet 910, the second adjustment mechanism 340 is configured to drive the second paper stop 320 to move along the first direction, thereby adjusting the size of the second paper tray 300 along the first direction (corresponding to the X-axis direction in the attached figure).

[0130] Optionally, one of the second paper stoppers 320 can be fixed, while the other second paper stopper 320 is connected to the output end of the second adjustment mechanism 340 and moves along the first direction under the drive of the second adjustment mechanism 340, thereby adjusting the size of the two second paper stoppers 320 along the first direction. This configuration makes the structure of the second adjustment mechanism 340 simple and easy to maintain.

[0131] Optionally, the second adjustment mechanism 340 can be connected to two second paper stoppers 320 simultaneously, and the second adjustment mechanism 340 is configured to drive the two second paper stoppers 320 to move towards each other or away from each other along a first direction, thereby adjusting the size of the two second paper stoppers 320 along the first direction. This configuration allows for rapid size adjustment between the two second paper stoppers 320.

[0132] Optionally, the second adjustment mechanism 340 may include a linear actuator such as a cylinder or a hydraulic cylinder, the linear actuator being fixed on the frame 920; the output end of the linear actuator is connected to the second paper stop 320, and the linear actuator drives the second paper stop 320 to move along the first direction.

[0133] Optionally, the second adjusting mechanism 340 may include a second adjusting motor and a second transmission component, the second transmission component being configured to convert the rotation of the second adjusting motor into linear movement along a first direction. For example, the second transmission component may include a gear and a rack; another example is that the second transmission component may include a lead screw and a nut; yet another example is that the second transmission component may be a belt drive component.

[0134] Optionally, the second adjustment mechanism 340 may include a second adjustment motor, a gear assembly, and a rack. The second adjustment motor may be fixed to the frame 920. The gear assembly includes a gear shaft and two gears mounted on the gear shaft. The gear shaft extends along a second direction, and the gears are fixed to both ends of the gear shaft. The gear shaft is drively connected to the output end of the second adjustment motor. The rack extends along a first direction. Two racks are provided, spaced apart along the second direction. The two racks mesh with the two gears respectively. The rack is connected to one of the second paper stoppers 320. The second adjustment motor drives the gear assembly to rotate, thereby causing the rack to move along the first direction, thus realizing the dimensional adjustment of the two second paper stoppers 320 along the first direction.

[0135] This embodiment of the present disclosure improves the reliability and accuracy of the movement of the second paper stop 320 along the first direction by setting two toothed racks, and reduces the impact of the second paper stop 320 being skewed on the placement of the second cardboard.

[0136] Optionally, a first guide rail pair can be provided between the frame 920 and the rack, allowing the rack and frame 920 to be slidably connected via the first guide rail pair. The first guide rail pair may include a first guide rail and a first slider. The first guide rail can extend along a first direction and can be connected to the frame 920; the first slider can slide on the first guide rail and can be connected to the rack. The first guide rail pair has high linear motion accuracy, which helps to improve the accuracy of the rack and the second paper stop 320 moving along the first direction.

[0137] Referring again to FIG2, the adhesive paper machine of this embodiment may include a first transfer member 20, which is configured to remove a first paperboard from a first paper tray 200 and convey the first paperboard to the bonding position in a second direction.

[0138] Optionally, the first transfer component 20 is configured to remove the first paperboard from the first paper feed port and convey the first paperboard to the bonding position in the second direction.

[0139] The adhesive paper machine of this disclosure embodiment may further include a second transfer component 30, which may be configured to remove a second paperboard from a second paper tray 300 and convey the second paperboard to the bonding position along a first direction.

[0140] Optionally, the second transfer member 30 is configured to remove the second paperboard from the second paper outlet and convey the second paperboard to the bonding position along the first direction.

[0141] Thus, compared to the paper-gluing structure inside the packaging machine, which is affected by the folding mechanism and has a large distance between the paper tray and the gluing position, resulting in a large travel distance and low efficiency when feeding the cardboard by the robotic arm, the paper-gluing in this embodiment involves the first transfer component 20 and the second transfer component 30 picking up paper from the second direction and the first direction respectively and feeding the cardboard. By feeding the paper towards each other from different directions (vertical direction perpendicular to the plane determined by the first direction and the second direction, and vertically opposite directions) to the gluing position, and then gluing the four pieces of cardboard together to form a carton, the vertically opposite feeding and gluing can shorten the paper-feeding stroke, increase the conveying and transfer speed of the cardboard, and improve the paper-gluing efficiency of the gluing machine.

[0142] It should be noted that, referring to Figure 1, before and / or at the bonding position, a portion of the second cardboard 12 and a portion of the first cardboard 11 are vertically conveyed by the first transfer member 20 and / or the second transfer member 30, and then vertically overlap and contact at the bonding position to achieve bonding. The overlapping area of ​​the first cardboard 11 and the second cardboard 12 is the bonding area 13.

[0143] At the bonding position, portions of the first cardboard 11 and the second cardboard 12 are bonded together. Thus, when the first transfer member 20 transfers the first cardboard to the bonding position, and the second transfer member 30 transfers the second cardboard to the bonding position, the first cardboard and the second cardboard are facing each other and in contact.

[0144] Optionally, when the first transfer member 20 transfers the first cardboard to the bonding position, the first transfer member 20 is configured to fix the first cardboard upwards, such that the first cardboard is above the fixed end of the first transfer member 20, i.e., the bonding surface of the first cardboard faces upwards. At the same time, when the second transfer member 30 transfers the second cardboard to the bonding position, the second transfer member 30 is configured to fix the second cardboard downwards, such that the second cardboard is below the fixed end of the second transfer member 30, i.e., the bonding surface of the second cardboard faces downwards. Thus, the first and second cardboards are vertically aligned and in contact.

[0145] Optionally, when the first transfer member 20 transfers the first cardboard to the bonding position, the first transfer member 20 is configured to fix the first cardboard downwards, such that the first cardboard is below the fixed end of the first transfer member 20, i.e., the bonding surface of the first cardboard faces downwards. At the same time, when the second transfer member 30 transfers the second cardboard to the bonding position, the second transfer member 30 is configured to fix the second cardboard upwards, such that the second cardboard is above the fixed end of the second transfer member 30, i.e., the bonding surface of the second cardboard faces upwards. Thus, the first and second cardboards are vertically aligned and in contact.

[0146] Optionally, when the first transfer member 20 transfers the first cardboard to the bonding position, the first transfer member 20 is configured to fix the first cardboard facing upwards; when the second transfer member 30 transfers the second cardboard to the bonding position, the second transfer member 30 is configured to fix the second cardboard facing upwards, such that the bonding surfaces of the first cardboard and the second cardboard are arranged opposite each other to achieve bonding between the first cardboard and the second cardboard. Alternatively, when the first transfer member 20 transfers the first cardboard to the bonding position, the first transfer member 20 is configured to fix the first cardboard facing downwards; when the second transfer member 30 transfers the second cardboard to the bonding position, the second transfer member 30 is configured to fix the second cardboard facing downwards, such that the bonding surfaces of the first cardboard and the second cardboard are arranged opposite each other to achieve bonding between the first cardboard and the second cardboard.

[0147] The embodiments disclosed herein provide a first transfer component 20 and a second transfer component 30 so that the first paperboard and the second paperboard are opposite to and in contact, which facilitates the bonding of the first paperboard and the second paperboard and improves the paper bonding efficiency.

[0148] Referring again to FIG2, optionally, the first transfer component 20 includes: a first paper picking structure 400, the first paper picking structure 400 being configured to pick up a first paperboard from the first paper tray 200, fix the first paperboard upward, and convey the first paperboard in a second direction.

[0149] The first paper-feeding structure 400 can be positioned below the first paper tray 200 to facilitate the removal of the first paperboard from the first paper-feeding port. Compared to methods such as a robotic arm with suction cups that pick up paperboard from the top of the paper tray, which cannot achieve continuous paper feeding and discharging, the layout of the first paper tray 200 above the first paper-feeding structure 400 allows the process of paperboard being placed into the paper tray and being conveyed from the bottom of the paper tray to occur simultaneously, thereby improving efficiency.

[0150] When the conveying mechanism 100 is provided with first paper bins 200 on both sides along the second direction, the first paper picking structure 400 is configured to pick up the first paperboard from the two first paper picking ports and convey the first paperboard along the second direction.

[0151] The first paperboard is located above the fixed end of the first paper-taking structure 400. The fixed end of the first paper-taking structure 400 is used to fix the first paperboard, and when the fixed end of the first paper-taking structure 400 fixes the first paperboard, the first paperboard is located above the fixed end of the first paper-taking structure 400.

[0152] It should be noted that the area of ​​the first paperboard is larger than the area of ​​the first paper dispensing opening, so that while the first paperboard passes through the exposed portion of the first paper dispensing opening, it is confined within the first paper tray 200. When the first paper dispensing structure 400 connects with the bottommost first paperboard, the first paper dispensing structure 400 causes the first paperboard to deform and detach from the first paper dispensing opening.

[0153] The first paper-taking structure 400 is configured to convey the first cardboard towards the conveying mechanism 100 along the second direction, and to convey the first cardboard to both sides of the conveying mechanism 100 along the second direction. The bonding position of the first cardboard and the second cardboard is located above the conveying mechanism 100, which facilitates the direct drop of the cardboard onto the conveying mechanism 100 after bonding, without the need for an additional transfer mechanism.

[0154] Therefore, the first transfer component 20 in this embodiment may further include a paper feeding structure 500, which is configured to take out the first paperboard from the first paper taking structure 400, fix the first paperboard downward, and transport the first paperboard to the bonding position in the second direction.

[0155] The paper feeding structure 500 can be located on the side of the first paper taking structure 400 away from the first paper tray 200. In other words, the paper feeding structure 500 is closer to the conveying mechanism 100 than the first paper taking structure 400.

[0156] The paper feeding structure 500 is configured to take out the first paperboard from the first paper taking structure 400 and convey the first paperboard in a second direction.

[0157] The first paperboard is located below the fixed end of the paper feeding structure 500. The fixed end of the paper feeding structure 500 is used to fix the first paperboard, and when the fixed end of the paper feeding structure 500 fixes the first paperboard, the first paperboard is located below the fixed end of the paper feeding structure 500.

[0158] Thus, the paper feeding structure 500 can not only transport the first paperboard taken out by the first paper taking structure 400 along the second direction to the top of the conveying mechanism 100, but also transfer the top-mounted first paperboard to the bottom side of the paper feeding structure 500, which facilitates the bonding of the first paperboard and the second paperboard.

[0159] In this embodiment, the first paperboard in the first paper bin 200 is conveyed to the top of the conveying mechanism 100 and to the bonding position via the first paper-picking structure 400 and the paper-feeding structure 500, awaiting bonding with the second paperboard. Furthermore, the first paper-picking structure 400 is used to pick up paper from the bottom, and the paper-feeding structure 500 transfers the first paperboard located at the top of the first paper-picking structure 400 to the bottom of the paper-feeding structure 500, facilitating bonding with the bottom-placed second paperboard. Compared to the bonding structure inside the packaging machine, which is affected by the folding mechanism and has a large distance between the paper bin and the bonding position, the paperboard is fed by a robotic arm. The cardboard travel is long and inefficient. In this embodiment, the first paper tray 200 is located above the first paper feeding structure 400, allowing the first cardboard to be directly fed out from the top of the first paper feeding structure 400. The paper feeding structure 500 is also located above the first paper feeding structure 400. The paper tray 200 and the paper feeding structure 500 are arranged close together, resulting in a compact structure and shortened travel. The upper position allows the cardboard topped by the first paper feeding structure 400 to be directly absorbed from the bottom, thus achieving positioning of the cardboard at the upper position of the second cardboard. The cardboard then travels through the first paper feeding structure 400 and the paper feeding structure 500... The transfer mechanism enables paperboard to enter from the top and exit from the bottom of the paper bin. After the first paper-picking structure 400 at the bottom tops and conveys the paperboard, the paperboard is then received by the lower part of the paper-feeding structure 500 at the top. This allows the first paperboard to be transferred to the top of the second paperboard via a U-shaped path through multiple devices for bonding. This process makes the conveying of the first paperboard simple and fast, eliminating the need for an additional flipping structure. This simplifies the structure of the gluing machine, and the processes of paper feeding, paper picking, horizontal conveying, and the transfer of the first paperboard from the bottom to the top are achieved without interference. At least partially, paper feeding and bottom picking can be integrated. The paper feeding process is carried out simultaneously. During the translational conveying process, the first paper picking structure 400 can independently achieve the relative rise of the first paperboard, and the paper feeding structure 500 can independently achieve the corresponding translational and lifting actions to the receiving position. There is no need to gradually achieve the above-mentioned related actions, which helps to reduce paper feeding actions and greatly reduce the total time to achieve the above-mentioned related actions, thereby improving efficiency. The first paper picking structure 400 and the paper feeding structure 500 directly connect to convey the first paperboard. The two can reduce the paper feeding path and reduce the lifting and conveying time of the paperboard by moving towards each other, thereby improving the working efficiency of the gluing machine.

[0160] Referring again to FIG2, the second transfer component 30 of this embodiment may include a second paper picking structure 600, which is configured to pick up a second paperboard from the second paper tray 300, fix the second paperboard upward, and convey the second paperboard to the bonding position along a first direction.

[0161] The second paper-feeding structure 600 can be positioned below the second paper tray 300, facilitating the removal of the second paperboard from the second paper-feeding port. Compared to methods such as a robotic arm with suction cups that pick up paperboard from the top of the paper tray, which cannot achieve continuous paperboard loading and unloading, the layout of the second paper tray 300 above the second paper-feeding structure 600 allows for simultaneous loading of paperboard into the paper tray and conveying of paperboard from the bottom of the paper tray, saving downtime for paperboard loading and thus improving efficiency.

[0162] When the conveying mechanism 100 is provided with second paper bins 300 on both sides along the first direction, the second paper picking structure 600 is configured to pick up the second paperboard from the two second paper picking ports respectively, and convey the second paperboard to the bonding position along the first direction, and bond the second paperboard to the first paperboard.

[0163] The second cardboard is positioned above the fixed end of the second paper-taking structure 600. The fixed end of the second paper-taking structure 600 is used to fix the second cardboard, and when the fixed end of the second paper-taking structure 600 fixes the second cardboard, the second cardboard is positioned above the fixed end of the second paper-taking structure 600. The second cardboard only needs to be placed on top of the second paper-taking structure 600 and then directly moved horizontally to below the first cardboard at the adhesive position. This eliminates the need for multiple components to handle the second cardboard, greatly simplifying the conveying process compared to the first cardboard, thus significantly simplifying the overall adhesive process and improving adhesive efficiency.

[0164] In this way, the second cardboard fixed at the fixed end of the second paper-taking structure 600 is bonded to the first cardboard fixed at the fixed end of the paper-feeding structure 500 without the need for flipping, which simplifies the paper-gluing operation.

[0165] It should be noted that the area of ​​the second paperboard is larger than the area of ​​the second paper dispensing opening, so that while the second paperboard passes through the exposed portion of the second paper dispensing opening, it is confined within the second paper tray 300. When the second paper dispensing structure 600 connects with the bottommost second paperboard, the second paper dispensing structure 600 causes the second paperboard to deform and detach from the second paper dispensing opening.

[0166] Optionally, the second transfer component 30 further includes a second paper feeding structure; the second paper feeding structure is configured to remove the second paperboard 12 from the second paper taking structure, fix the second paperboard 12 downward, and convey the second paperboard 12 to the bonding position along the first direction.

[0167] Optionally, the second paper feeding structure is configured to move the second paperboard 12 vertically and in the first direction.

[0168] Optionally, the second transfer component 30 includes a second paper-picking structure and a second paper-feeding structure; the second paper-picking structure is configured to pick up the second paperboard 12 from the second paper tray, fix the second paperboard 12 upwards, and convey the second paperboard 12 along a first direction; the second paper-feeding structure is configured to pick up the second paperboard 12 from the second paper-picking structure, fix the second paperboard 12 downwards, and convey the second paperboard 12 to the bonding position along the first direction. Optionally, the second paper-picking structure is configured to drive the second paperboard 12 to move vertically and along the first direction; the second paper-feeding structure is configured to drive the second paperboard 12 to move vertically and along the first direction.

[0169] That is, the structure of the second transfer component 30 provided in this embodiment can be the same as that of the first transfer component 20. Its specific construction has been fully explained based on the detailed description of the first transfer component 20, so the second transfer component 30 will not be described again.

[0170] Referring again to FIG2, the adhesive machine of this embodiment may further include an adhesive applicator 700, which is configured to output adhesive to both ends of the first or second paperboard when the first paperboard and the second paperboard are moving.

[0171] The adhesive applicator 700 is configured to deliver adhesive to both ends of the first or second paperboard during its movement from the paper tray to the bonding position, so that the first and second paperboards can be bonded at the bonding position.

[0172] Optionally, as the second paperboard moves along the first direction, the gluing mechanism 700 is configured to dispense adhesive to both ends of the second paperboard. Thus, during the process from when the second paper-taking structure 600 removes the second paperboard from the second paper tray 300 to when it moves along the first direction below the paper-feeding structure 500, the gluing mechanism 700 is configured to dispense adhesive to both ends of the second paperboard.

[0173] Optionally, when the paper feeding structure 500 conveys the first paperboard in the second direction, the glue application mechanism 700 is configured to output adhesive to both ends of the first paperboard to facilitate the bonding of the first paperboard and the second paperboard.

[0174] Optionally, the glue application mechanism 700 includes a glue dispensing machine 710 and a glue gun 720, which can be fixed to the frame 920 respectively. The glue gun 720 can be positioned on the movement path of the second cardboard along the first direction. Optionally, the glue gun 720 is located between the second paper tray 300 and the bonding position. The glue gun 720 can also be positioned in other locations, which are not limited here.

[0175] Thus, under the control of the control cabinet 910, the dispensing machine 710 outputs adhesive to the glue gun 720, causing the glue gun 720 to output adhesive onto the second cardboard.

[0176] Optionally, four glue guns 720 are provided, arranged in a rectangular matrix, so as to simultaneously output adhesive at both ends of the two second cardboards, reduce the glue application time, and thus improve the efficiency of the gluer.

[0177] Optionally, referring to Figure 6, two glue guns 720 are fixed to the side of the second paper tray 300 facing the other second paper tray 300, and the two glue guns 720 are spaced apart along the second direction, so as to simultaneously apply glue to both ends of the second paperboard along the second direction. Two other glue guns 720 are fixed to the side of another second paper tray 300 facing the first second paper tray 300, so as to simultaneously apply glue to both ends of another second paperboard along the second direction.

[0178] Referring to Figures 2 and 3, optionally, the first paper-grabbing structure 400 is configured to drive the first cardboard to move vertically and in the second direction. Through the independent vertical and second-direction movement of the first paper-grabbing structure 400, paper grabbing and the position adjustment of the first cardboard in the vertical and second directions are achieved. Understandably, this can be performed simultaneously or sequentially with the position adjustment of the paper feeding structure 500. The vertical movement of the first paper-grabbing structure 400 can also shorten the paper-grabbing and placing stroke of a single device. When performed simultaneously with the position adjustment of the paper feeding structure 500, their coordinated operation helps to shorten the component travel distance, reduce the total time of related actions, and improve paper-sticking efficiency.

[0179] Optionally, the first paper-taking structure 400 may include a first driving mechanism, two first lifting mechanisms 420 and two first suction mechanisms 430.

[0180] The output end of the first drive mechanism is connected to two first lifting mechanisms 420, and the first drive mechanism is configured to drive the two first lifting mechanisms 420 to move along the second direction.

[0181] The output of each first lifting mechanism 420 is connected to a first adsorption mechanism 430, and the first lifting mechanism 420 is configured to drive the first adsorption mechanism 430 to move vertically; wherein, the vertical direction, the first direction, and the second direction are perpendicular to each other. The vertical direction corresponds to the Z-axis direction in the attached figure.

[0182] The first lifting mechanism 420 may include a first cylinder, the output end of which is connected to the first adsorption mechanism 430. The first cylinder is electrically connected to the control cabinet 910, so that the first cylinder drives the first adsorption mechanism 430 to move vertically under the control of the control cabinet 910.

[0183] Multiple first cylinders can be provided, and the multiple first cylinders are arranged at intervals along the first direction, thereby improving the reliability and stability of the first lifting mechanism 420 driving the first adsorption mechanism 430 to move up and down.

[0184] Optionally, the first lifting mechanism 420 further includes a first mounting base, which is fixed to the output end of the first drive mechanism, and the first cylinder is mounted on the first mounting base. The first mounting base provides space for the installation of the first cylinder and connects the first cylinder to the output end of the first drive mechanism.

[0185] Optionally, a second guide rail pair is provided between the first mounting base and the output end of the first cylinder to guide the vertical movement of the output end of the first cylinder. The second guide rail pair may include a second guide rail and a second slider, with the second slider slidably mounted on the second guide rail, which extends vertically. One of the second guide rail and the second slider is fixed to the first mounting base, and the other is fixed to the output end of the first cylinder or to the first adsorption mechanism 430. The second guide rail pair has high linear motion accuracy, which helps to improve the accuracy of the vertical movement of the first adsorption mechanism 430.

[0186] Both first adsorption mechanisms 430 extend along a first direction, and the two first adsorption mechanisms 430 are configured to adsorb the first paperboard from the two first paper dispensing ports respectively, and release the first paperboard at a preset position.

[0187] Optionally, the first adsorption mechanism 430 includes a plurality of first suction cups, which are spaced apart along a first direction to improve the reliability and stability of the first adsorption mechanism 430 in adsorbing the first cardboard.

[0188] The openings of the multiple first suction cups face upwards, which facilitates paper retrieval from the bottom of the first paper tray 200 and positions the first cardboard at the top of the first suction cups.

[0189] The first adsorption mechanism 430 may further include a first mounting plate extending along a first direction. The first mounting plate may be fixed to the output end of the first lifting mechanism 420. Multiple first suction cups may be mounted on the first mounting plate.

[0190] An airflow channel can also be formed inside the first mounting plate. The airflow channel is connected to the first suction cup to enable air intake and exhaust of the first suction cup.

[0191] The first adsorption mechanism 430 may further include a first air pump configured to draw air into the first suction cup through an air tube and an airflow channel, thereby adsorbing the first cardboard onto the first suction cup; the first air pump is also configured to release air from the first suction cup through the air tube and the airflow channel, thereby causing the first cardboard to fall off the first suction cup.

[0192] In this embodiment, the first paper-taking structure 400 adsorbs and releases the first cardboard through the first adsorption mechanism 430, simplifying the connection and release structure between the first adsorption mechanism 430 and the first cardboard. The first lifting mechanism 420 vertically elevates the first adsorption mechanism 430, thus moving the first cardboard vertically. A first driving mechanism drives the first lifting mechanism 420 and the first adsorption mechanism 430 to move along a second direction, thereby moving the first cardboard along that direction. Thus, this embodiment achieves paper taking and position adjustment of the first cardboard along the vertical and second directions through the first driving mechanism, the first lifting mechanism 420, and the first adsorption mechanism 430, simplifying the paper-taking structure and the paper-taking and feeding actions, thereby improving paper-adhesion efficiency.

[0193] Optionally, the first driving mechanism includes two drivers, each connected to one of the two first lifting mechanisms 420 via two transmission components, thereby driving the two first lifting mechanisms 420 to move towards or away from each other along the second direction. This arrangement allows for independent control of the movement of the two first cardboard pieces along the first direction, resulting in higher precision and more flexible control.

[0194] In the embodiments of this disclosure, when the two components move toward each other, the two components move towards each other and the distance between the two components decreases; when the two components move away from each other, the two components move away from each other and the distance between the two components increases.

[0195] Optionally, the first drive mechanism may include a first motor and a first transmission assembly 412. The first motor is connected to two first lifting mechanisms 420 through the first transmission assembly 412, that is, the movement of two first cardboard pieces along a first direction is achieved by using one first motor. In this way, the equipment cost can be reduced and the control logic can be relatively simple; it can also make the first drive mechanism 410 compact and occupy less installation space.

[0196] Referring again to Figure 3, optionally, the first transmission assembly 412 may include a first transmission belt 4122 and two first transmission pulleys 4121 spaced apart along a second direction. The first transmission belt 4122 is wound around the two first transmission pulleys 4121. A first motor is configured to drive one of the first transmission pulleys 4121 to rotate. The first motor is connected to one of the first transmission pulleys 4121, thereby driving the first transmission pulley 4121 to rotate. This first transmission pulley 4121 is the driving pulley; the other first transmission pulley 4121 is the driven pulley.

[0197] The first transmission belt 4122 includes a first upper translation belt portion and a first lower translation belt portion that are vertically opposite to each other and spaced apart. The first upper translation belt portion is located above the two first transmission wheels 4121 and is suspended relative to the first transmission wheels 4121; the first lower translation belt portion is located below the two first transmission wheels 4121 and is suspended relative to the first transmission wheels 4121.

[0198] One of the first lifting mechanisms 420 is fixed to the first upper transmission belt 41221, and the other first lifting mechanism 420 is fixed to the first lower transmission belt 41222, so that the first motor drives the two first lifting mechanisms 420 to move towards each other or away from each other in the second direction.

[0199] When the first motor rotates in a certain direction, it drives the first transmission belt 4122 to move via the first transmission wheel 4121. As shown in Figure 3, the first upper translation belt moves in the positive direction of the second direction (i.e., the positive direction of the Y-axis in the figure), and the first lower translation belt moves in the negative direction of the second direction (i.e., the negative direction of the Y-axis in the figure), thereby causing the two first lifting mechanisms 420 and the two first adsorption mechanisms 430 to move towards each other.

[0200] When the first motor rotates in the opposite direction of a certain direction, it drives the first transmission belt 4122 to move through the first transmission wheel 4121. As shown in Figure 3, the first upper translation belt moves in the negative direction of the second direction (i.e., the negative direction of the Y-axis in the figure), and the first lower translation belt moves in the positive direction of the second direction (i.e., the positive direction of the Y-axis in the figure), thereby causing the two first lifting mechanisms 420 and the two first adsorption mechanisms 430 to move in opposite directions.

[0201] Optionally, two first transmission components 412 are provided, spaced apart along a first direction. One first transmission component 412 is connected to the first motor, and the other first transmission component 412 serves as a driven component. The first lifting mechanism 420 is connected to the two first transmission components 412, and the first drive mechanism 410 supports the reliability and stability of the first lifting mechanism 420 and the first adsorption mechanism 430.

[0202] The first drive mechanism 410 of this embodiment uses a belt drive mechanism to realize the opposite and backward movement of the two first lifting mechanisms 420 along the second direction. The structure is simple and easy to install and maintain. Moreover, the belt drive structure conveys the first cardboard smoothly and with low noise.

[0203] Referring to Figures 2 and 4, optionally, the paper feeding structure 500 can be configured to move the first cardboard vertically and in the second direction. Through the independent vertical and second-direction movement of the paper feeding structure 500, the position of the first cardboard can be quickly adjusted to facilitate cooperation with the first paper picking structure 400, enabling the switching of the first cardboard from top to bottom position and the transfer of paper to the adhesive position. Understandably, the position adjustment with the first paper picking structure 400 can be performed simultaneously or sequentially. The vertical movement of the paper feeding structure 500 can also shorten the paper picking and placing stroke of a single device. When the position adjustment of the first paper picking structure 400 is performed simultaneously, the coordinated movement helps to shorten the relative travel of components, reduce the total time of related actions, and improve adhesive efficiency.

[0204] Optionally, the paper feeding structure 500 may include: a second drive mechanism 510, two second lifting mechanisms 520 and two second suction mechanisms 530.

[0205] The output end of the second drive mechanism 510 is connected to the two second lifting mechanisms 520, and the second drive mechanism 510 is configured to drive the two second lifting mechanisms 520 to move along the second direction.

[0206] The output of each second lifting mechanism 520 is connected to a second adsorption mechanism 530, and the second lifting mechanism 520 is configured to drive the second adsorption mechanism 530 to move vertically.

[0207] The second lifting mechanism 520 may include a second cylinder, the output end of which is connected to the second adsorption mechanism 530. The second cylinder is electrically connected to the control cabinet 910, so that the second cylinder drives the second adsorption mechanism 530 to move vertically under the control of the control cabinet 910.

[0208] Multiple second cylinders can be provided, and the multiple second cylinders are arranged at intervals along the first direction, thereby improving the reliability and stability of the second lifting mechanism 520 driving the second adsorption mechanism 530 to move up and down.

[0209] Optionally, the second lifting mechanism 520 may further include a second mounting base, which is fixed to the output end of the second drive mechanism 510, and the second cylinder is mounted on the second mounting base. The second mounting base provides space for the installation of the second cylinder and connects the second cylinder to the output end of the second drive mechanism 510.

[0210] Optionally, a third guide rail pair is provided between the second mounting base and the output end of the second cylinder to guide the vertical movement of the output end of the second cylinder. The third guide rail pair may include a third guide rail and a third slider, with the third slider slidably mounted on the third guide rail, which extends vertically. One of the third guide rail and the third slider is fixed to the second mounting base, and the other is fixed to the output end of the second cylinder or to the second adsorption mechanism 530. The third guide rail pair has high linear motion accuracy, which helps to improve the accuracy of the vertical movement of the second adsorption mechanism 530.

[0211] Both second adsorption mechanisms 530 extend along the first direction, and the two second adsorption mechanisms 530 are configured to adsorb the first paperboard from the two first paper-taking structures 400 respectively.

[0212] Optionally, the second adsorption mechanism 530 may include a plurality of second suction cups, which are spaced apart along the first direction to improve the reliability and stability of the second adsorption mechanism 530 in adsorbing the first cardboard.

[0213] The openings of the multiple second suction cups face downwards, which facilitates the picking up of the first paperboard from the first paper-picking mechanism and allows the first paperboard to switch from a top-down position to a bottom position, making it easier to bond with the second paperboard.

[0214] The second adsorption mechanism 530 may further include a second mounting plate extending along the first direction. The second mounting plate may be fixed to the output end of the second lifting mechanism 520. Multiple second suction cups may be mounted on the second mounting plate.

[0215] An airflow channel can also be formed inside the second mounting plate. The airflow channel is connected to the second suction cup to enable air intake and exhaust of the second suction cup.

[0216] The second adsorption mechanism 530 may further include a second air pump configured to draw air into the second suction cup through an air tube and an airflow channel, thereby adsorbing the first cardboard onto the second suction cup; the second air pump is also configured to release air from the second suction cup through the air tube and the airflow channel, thereby causing the first cardboard to fall off the second suction cup.

[0217] In this embodiment, the paper feeding structure 500 uses a second adsorption mechanism 530 to adsorb and release the first cardboard, simplifying the connection and release structure between the second adsorption mechanism 530 and the first cardboard. A second lifting mechanism 520 enables the second adsorption mechanism 530 to move vertically, thereby moving the first cardboard vertically. A second driving mechanism 510 drives the second lifting mechanism 520 and the second adsorption mechanism 530 to move in a second direction, thus moving the first cardboard in that direction. Therefore, this embodiment uses the second driving mechanism 510, the second lifting mechanism 520, and the second adsorption mechanism 530 to achieve paper picking and position adjustment of the first cardboard in both the vertical and second directions. This simplifies the paper feeding structure 500, making the paper picking and feeding actions simple and improving paper adhesion efficiency.

[0218] Optionally, the second drive mechanism 510 may include two drivers, each connected to a second lifting mechanism 520 via two transmission components, thereby driving the two second lifting mechanisms 520 to move towards or away from each other along the second direction. This arrangement allows for independent control of the movement of the two first cardboard pieces along the first direction, resulting in higher precision and more flexible control.

[0219] Optionally, the second drive mechanism 510 includes a second motor and a second transmission assembly. The second motor is connected to two second lifting mechanisms 520 via the second transmission assembly, meaning that one second motor is used to move the two first cardboard pieces along a first direction. This reduces equipment costs and simplifies the control logic; it also makes the second drive mechanism 510 compact and requires less installation space.

[0220] Referring again to Figure 4, optionally, the second transmission assembly may include a second transmission belt and two second transmission pulleys spaced apart along a second direction, with the second transmission belt wound around the two second transmission pulleys; a second motor is configured to drive one of the second transmission pulleys to rotate. The second motor is connected to one of the second transmission pulleys, thereby driving that second transmission pulley to rotate; this second transmission pulley is the driving pulley; the other second transmission pulley is the driven pulley.

[0221] The second transmission belt may include a second upper translation belt portion and a second lower translation belt portion that are vertically opposite to each other and spaced apart. The second upper translation belt portion is located above the two second transmission wheels and suspended relative to the second transmission wheels; the second lower translation belt portion is located below the two second transmission wheels and suspended relative to the second transmission wheels.

[0222] One of the second lifting mechanisms 520 is fixed to the second upper transmission belt section, and the other second lifting mechanism 520 is fixed to the second lower transmission belt section, so that the second motor drives the two second lifting mechanisms 520 to move towards each other or away from each other in the second direction.

[0223] When the second motor rotates in a certain direction, it drives the second transmission belt to move via the second transmission wheel. As shown in Figure 4, the second upper translation belt moves in the positive direction of the second direction (i.e., the positive direction of the Y-axis in the figure), and the second lower translation belt moves in the negative direction of the second direction (i.e., the negative direction of the Y-axis in the figure), thereby causing the two second lifting mechanisms 520 and the two second suction mechanisms 530 to move towards each other. Understandably, the relevant structures of the second upper and lower translation belts are not explicitly shown in Figure 4; their specific structures and operating methods are shown in the relevant structures and operating methods of the first transmission assembly 412 in Figures 3 and 4.

[0224] When the second motor rotates in the opposite direction of a certain direction, it drives the second transmission belt to move via the second transmission wheel. As shown in Figure 4, the second upper translation belt moves in the negative direction of the second direction (i.e., the negative direction of the Y-axis in the figure), and the second lower translation belt moves in the positive direction of the second direction (i.e., the positive direction of the Y-axis in the figure), thereby causing the two second lifting mechanisms 520 and the two second adsorption mechanisms 530 to move in opposite directions.

[0225] Optionally, two second transmission components are provided, spaced apart along the first direction. One second transmission component is connected to the second motor, and the other serves as a driven component. The second lifting mechanism 520 is connected to the two second transmission components, and the second drive mechanism 510 supports the second lifting mechanism 520 and the second adsorption mechanism 530 with reliability and stability.

[0226] The second drive mechanism 510 of this embodiment uses a belt drive mechanism to realize the opposite and backward movement of the two second lifting mechanisms 520 along the second direction. The structure is simple and easy to install and maintain. Moreover, the belt drive structure conveys the first cardboard smoothly and with low noise.

[0227] Referring to Figures 2 and 5, optionally, the second paper-taking structure 600 is configured to move the second paperboard vertically and in the first direction.

[0228] The second paper-taking structure 600 can move independently in the vertical and first directions, allowing the second paperboard to be quickly adjusted in position along these directions to facilitate coordination with the paper-feeding structure 500. When the first paperboard switches from a top-to-bottom position or is moved to the adhesive position, the second paperboard moves from the top position to the adhesive position via the second paper-taking structure 600, thus achieving adhesive bonding between the first and second paperboards. Understandably, the position adjustment of the second paper-taking structure 600 and the paper-feeding structure 500 can be performed simultaneously or sequentially. The vertical movement of the second paper-taking structure 600 can also shorten the paper-taking and dispensing stroke of a single device. When the position adjustment of the paper-feeding structure 500 is performed simultaneously, their coordinated operation helps to shorten the relative travel distance of components, reduce the total time of related actions, and improve adhesive bonding efficiency.

[0229] Optionally, the second paper-taking structure 600 may include a third driving mechanism 610, two third lifting mechanisms 620, and two third suction mechanisms 630.

[0230] The output end of the third drive mechanism 610 is connected to the two third lifting mechanisms 620, and the third drive mechanism 610 is configured to drive the two third lifting mechanisms 620 to move along the first direction.

[0231] The output of each third lifting mechanism 620 is connected to a third adsorption mechanism 630, and the third lifting mechanism 620 is configured to drive the third adsorption mechanism 630 to move vertically.

[0232] The third lifting mechanism 620 may include a third cylinder, the output end of which is connected to the third adsorption mechanism 630. The third cylinder is electrically connected to the control cabinet 910, thus, under the control of the control cabinet 910, the third cylinder drives the third adsorption mechanism 630 to move vertically.

[0233] Multiple third cylinders can be provided, and the multiple third cylinders are arranged at intervals along the first direction, thereby improving the reliability and stability of the third lifting mechanism 620 driving the third adsorption mechanism 630 to move up and down.

[0234] Optionally, the third lifting mechanism 620 may further include a third mounting base, which is fixed to the output end of the third drive mechanism 610, and the third cylinder is mounted on the third mounting base. The third mounting base provides space for the installation of the third cylinder and connects the third cylinder to the output end of the third drive mechanism 610.

[0235] Optionally, a fourth guide rail pair is provided between the third mounting base and the output end of the third cylinder to guide the vertical movement of the output end of the third cylinder. The fourth guide rail pair may include a fourth guide rail and a fourth slider, with the fourth slider slidably mounted on the fourth guide rail, which extends vertically. One of the fourth guide rail and the fourth slider is fixed to the third mounting base, and the other is fixed to the output end of the third cylinder, or to the third adsorption mechanism 630. The fourth guide rail pair has high linear motion accuracy, which helps improve the accuracy of the vertical movement of the third adsorption mechanism 630.

[0236] Both third adsorption mechanisms 630 extend along the second direction, and the two third adsorption mechanisms 630 are configured to adsorb the second paperboard from the two second paper dispensing ports respectively, and release the second paperboard at the bonding position.

[0237] Optionally, the third adsorption mechanism 630 may include a plurality of third suction cups, which are spaced apart along the second direction to improve the reliability and stability of the adsorption of the second cardboard by the third adsorption mechanism 630.

[0238] The openings of the multiple third suction cups face upwards, which facilitates paper retrieval from the bottom of the second paper tray 300 and positions the second cardboard at the top of the third suction cups.

[0239] The third suction mechanism 630 may further include a third mounting plate extending along the second direction. The third mounting plate may be fixed to the output end of the third lifting mechanism 620. Multiple third suction cups may be mounted on the third mounting plate.

[0240] An airflow channel can also be constructed within the third mounting plate, which is connected to the third suction cup to enable air intake and exhaust from the third suction cup.

[0241] The third adsorption mechanism 630 may also include a third air pump configured to draw air into the third suction cup through an air tube and an airflow channel, thereby adsorbing the second cardboard onto the third suction cup; the third air pump is also configured to release air from the third suction cup through the air tube and the airflow channel, thereby causing the second cardboard to fall off the third suction cup.

[0242] In this embodiment, the second paper-taking structure 600 adsorbs and releases the second cardboard through the third adsorption mechanism 630, simplifying the connection and release structure between the third adsorption mechanism 630 and the second cardboard. The third lifting mechanism 620 vertically elevates the third adsorption mechanism 630, enabling vertical movement of the second cardboard. The third driving mechanism 610 drives the third lifting mechanism 620 and the third adsorption mechanism 630 along a first direction, thus moving the second cardboard along that direction. Therefore, this embodiment achieves paper taking and position adjustment of the second cardboard along the vertical and first directions through the third driving mechanism 610, the third lifting mechanism 620, and the third adsorption mechanism 630, simplifying the paper-taking structure and the paper-taking and feeding actions, thereby improving paper-adhesion efficiency.

[0243] Optionally, the third drive mechanism 610 may include two drivers, each connected to two third lifting mechanisms 620 via two transmission components, thereby driving the two third lifting mechanisms 620 to move towards or away from each other along the first direction. This arrangement allows for independent control of the movement of the two second cardboard pieces along the first direction, resulting in higher precision and more flexible control.

[0244] Optionally, the third drive mechanism 610 includes a third motor and a third transmission assembly. The third motor is connected to two third lifting mechanisms 620 via the third transmission assembly, meaning that one third motor is used to move the two second cardboard pieces along the first direction. This reduces equipment costs and simplifies the control logic; it also makes the third drive mechanism 610 compact and requires less installation space.

[0245] Referring again to Figure 3, optionally, the third transmission assembly may include a third transmission belt and two third transmission pulleys spaced apart along a first direction, with the third transmission belt wound around the two third transmission pulleys; a third motor is configured to drive one of the third transmission pulleys to rotate. The third motor is connected to one of the third transmission pulleys, thereby driving the third transmission pulley to rotate, and the third transmission pulley is the driving pulley; the other third transmission pulley is the driven pulley.

[0246] The third transmission belt may include a third upper translation belt portion and a third lower translation belt portion that are vertically opposite and spaced apart. The third upper translation belt portion is located above the two third transmission wheels and suspended relative to the third transmission wheels; the third lower translation belt portion is located below the two third transmission wheels and suspended relative to the third transmission wheels.

[0247] One of the third lifting mechanisms 620 is fixed to the third upper transmission belt section, and the other third lifting mechanism 620 is fixed to the third lower transmission belt section, so that the third motor drives the two third lifting mechanisms 620 to move towards each other or away from each other in the first direction.

[0248] When the third motor rotates in a certain direction, it drives the third transmission belt to move via the third transmission wheel. As shown in Figure 5, the third upper translation belt moves along the positive direction of the first direction (i.e., the positive direction of the X-axis in the figure), and the third lower translation belt moves along the negative direction of the first direction (i.e., the negative direction of the X-axis in the figure), thereby causing the two third lifting mechanisms 620 and the two third adsorption mechanisms 630 to move towards each other. Understandably, the relevant structures of the third upper and lower translation belts are not explicitly shown in Figure 5; their specific structures and operating methods are shown in the relevant structures and operating methods of the first transmission assembly 412 in Figures 3 and 4.

[0249] When the third motor rotates in the opposite direction of a certain direction, it drives the third transmission belt to move through the third transmission wheel. As shown in Figure 5, the third upper translation belt moves in the negative direction of the first direction (i.e., the negative direction of the X-axis in the figure), and the third lower translation belt moves in the positive direction of the first direction (i.e., the positive direction of the X-axis in the figure), thereby causing the two third lifting mechanisms 620 and the two third adsorption mechanisms 630 to move in opposite directions.

[0250] Optionally, two third transmission components are provided, spaced apart along the first direction. One third transmission component is connected to the third motor, and the other serves as a driven component. The third lifting mechanism 620 is connected to the two third transmission components, and the third drive mechanism 610 supports the reliability and stability of the third lifting mechanism 620 and the third adsorption mechanism 630.

[0251] The third drive mechanism 610 of this embodiment uses a belt drive mechanism to realize the opposite and backward movement of the two third lifting mechanisms 620 along the first direction. The structure is simple and easy to install and maintain. Moreover, the belt drive structure transports the second cardboard smoothly and with low noise.

[0252] Referring to Figures 2, 5 and 6, optionally, the adhesive press also includes a support structure 800, which is configured to support at least the overlapping portion of the first and second paperboards at the adhesive position.

[0253] Optionally, when the first cardboard and the second cardboard are bonded, the support structure 800 is configured to support the second cardboard, so that the bonding between the first cardboard and the second cardboard is more stable and reliable.

[0254] Optionally, the support structure 800 may include a support plate 820 for supporting at least the overlapping portion of the first cardboard and the second cardboard; the support plate 820 is configured to move along a first direction to support at least the overlapping portion of the first cardboard and the second cardboard, or to detach from the overlapping portion of the first cardboard and the second cardboard so that the bonded first cardboard and the second cardboard fall into the conveying mechanism 100.

[0255] Optionally, the support structure 800 includes a fourth drive mechanism 810, which is connected to the support plate 820 to drive the support plate 820 to move along a first direction.

[0256] Optionally, two support plates 820 are provided, and the two support plates 820 are located above the conveying mechanism 100. The fourth drive mechanism 810 is connected to the two support plates 820 respectively to drive the two support plates 820 to move towards each other or away from each other along the first direction.

[0257] Two support plates 820 extend along a second direction and are spaced apart along a first direction.

[0258] The second paper-feeding structure 600 is configured to convey the second paperboard along a first direction until at least a portion of the second paperboard is located on the support plate 820; then, the paper-feeding structure 500 is configured to drive the first paperboard to contact and bond with the second paperboard.

[0259] The support structure 800 of this embodiment drives two support plates 820 to move towards each other via a fourth driving mechanism 810. This allows the two support plates 820 to move along a first direction to the bonding position, so that at least a portion of the second paperboard conveyed by the second paper-taking structure 600 is located on the support plates 820, providing support for the second paperboard. The fourth driving mechanism 810 can also drive the two support plates 820 to move away from each other, thereby widening the gap between the two support plates 820 along the first direction. This allows the bonded carton board 10 to fall from between the two support plates 820 onto the conveying mechanism 100. This configuration improves the reliability and stability of the bonding operation between the first and second paperboards and allows the bonded carton board 10 to fall from between the two support plates 820 onto the conveying mechanism 100, realizing the conveying of the carton board 10 from the bonding position to the conveying mechanism 100 without the need for an additional transfer structure, thus simplifying the structure of the gluing machine.

[0260] Optionally, the fourth drive mechanism 810 includes a fourth motor and a fourth transmission assembly. The fourth motor is connected to the two support plates 820 via the fourth transmission assembly, meaning that one fourth motor is used to move the two support plates 820 along the first direction. This reduces equipment costs and simplifies the control logic; it also makes the fourth drive mechanism 810 compact and requires less installation space.

[0261] The fourth transmission component can be located outside the third transmission component.

[0262] Referring again to Figure 2, optionally, the fourth transmission assembly may include a fourth transmission belt and two fourth transmission pulleys spaced apart along a first direction, with the fourth transmission belt wound around the two fourth transmission pulleys; a fourth motor is configured to drive one of the fourth transmission pulleys to rotate. The fourth motor is connected to one of the fourth transmission pulleys, thereby driving that fourth transmission pulley to rotate; this fourth transmission pulley is the driving pulley; the other fourth transmission pulley is the driven pulley.

[0263] The fourth transmission belt may include a fourth upper translation belt portion and a fourth lower translation belt portion that are vertically opposite to each other and spaced apart. The fourth upper translation belt portion is located above the two fourth transmission pulleys and is suspended relative to the fourth transmission pulleys; the fourth lower translation belt portion is located below the two fourth transmission pulleys and is suspended relative to the fourth transmission pulleys.

[0264] One of the support plates 820 is fixed to the fourth upper transmission belt section, and the other support plate 820 is fixed to the fourth lower transmission belt section, so that the fourth motor drives the two support plates 820 to move towards each other or away from each other in the first direction.

[0265] When the fourth motor rotates in a certain direction, it drives the fourth transmission belt to move via the fourth transmission wheel. As shown in Figure 2, the fourth upper translation belt moves in the positive direction of the first direction (i.e., the positive direction of the X-axis in the figure), and the fourth lower translation belt moves in the negative direction of the first direction (i.e., the negative direction of the X-axis in the figure), thereby causing the two support plates 820 and the two fourth adsorption mechanisms to move towards each other.

[0266] When the fourth motor rotates in the opposite direction of a certain direction, it drives the fourth transmission belt to move via the fourth transmission wheel. As shown in Figure 2, the fourth upper translation belt moves in the negative direction of the first direction (i.e., the negative direction of the X-axis in the figure), and the fourth lower translation belt moves in the positive direction of the first direction (i.e., the positive direction of the X-axis in the figure), thereby causing the two support plates 820 and the two fourth adsorption mechanisms to move in opposite directions.

[0267] Optionally, two fourth transmission components are provided, spaced apart along the first direction. One fourth transmission component is connected to the fourth motor, and the other serves as a driven component. The support plate 820 is connected to the two fourth transmission components, and the fourth drive mechanism 810 ensures the reliability and stability of the support plate 820 and the fourth adsorption mechanism.

[0268] The fourth drive mechanism 810 of this embodiment uses a belt drive mechanism to realize the opposite and opposite movement of the two support plates 820 along the first direction. It has a simple structure and is easy to install and maintain. Moreover, the belt drive structure transports the second cardboard smoothly and with low noise.

[0269] Alternatively, the adhesive paper machine provided in this embodiment may not have a support structure 800, and the adhesive position may be directly set on the conveying mechanism 100.

[0270] This disclosure also provides a gluing machine, independent of the packaging machine, for assembling a cardboard box 10 with a central cutout, comprising: a conveying mechanism 100, a first paper bin 200, a second paper bin 300, a first transfer component 20, and a second transfer component 30; the conveying mechanism 100 is configured to convey the cardboard box 10 along a first direction; wherein the cardboard box 10 includes a first paperboard 11 and a second paperboard 12; the first paper bin 200 is configured to receive the first paperboard 11; the second paper bin 300 is configured to receive the second paperboard 300; the first transfer component 20 is configured to transfer from the first paper bin... 200 removes the first cardboard 11 and conveys it along the second direction to the bonding position; wherein the second direction intersects the first direction; the second transfer member 30 is configured to remove the second cardboard 12 from the second paper tray 300 and convey it along the first direction to the bonding position; before and / or at the bonding position, a portion of the second cardboard 12 and a portion of the first cardboard 11 are conveyed vertically by the first transfer member 20 and / or the second transfer member 30, and are vertically overlapped and bonded at the bonding position; wherein the vertical direction is perpendicular to the plane defined by the first direction and the second direction.

[0271] Optionally, the adhesive applicator also includes an adhesive applicator 700, which is configured to dispense adhesive to both ends of the first cardboard 11 or the second cardboard 12, thereby bonding the first cardboard 11 and the second cardboard 12 at the bonding positions. That is, the adhesive applicator 700 can apply adhesive while the first cardboard 11 and the second cardboard 12 are moving, or when the first cardboard 11 and the second cardboard 12 are stationary; this is not limited to this. More specifically, the adhesive applicator 700 can apply adhesive during the conveying of the first cardboard 11 and the second cardboard 12, or when the first transfer member 20 and the second transfer member 30 have stopped moving and the first cardboard 11 and the second cardboard 12 are stationary. The adhesive applicator 700 has the same structure as described above and will not be repeated here.

[0272] Optionally, the gluing mechanism 700 may not be provided. Instead, an adhesive component, such as glue, may be provided at the bonding area of ​​the first cardboard 11 and the second cardboard 12 to bond the first cardboard 11 and the second cardboard 12 together to form a cardboard box 10 with a hollow center.

[0273] The adhesive paper machine provided in this disclosure may also include all other structures of the adhesive paper machine in the foregoing embodiments. The relevant details have been fully described above and will not be repeated here to avoid redundancy.

[0274] The following describes the paper-sticking process of the paper-sticking machine according to an embodiment of the present disclosure.

[0275] After the paper gluing machine is started, the control cabinet 910 controls the operation of the conveying mechanism 100, the first paper picking structure 400, the paper feeding structure 500, the second paper picking structure 600, and the support structure 800.

[0276] Specifically, the control cabinet 910 controls the first drive mechanism 410 to drive the two first lifting mechanisms 420 and the two first suction mechanisms 430 to move in opposite directions along a second direction; and controls the first suction mechanism 430 to suction the first paperboard through the first paper dispensing port; and controls the first lifting mechanism 420 to drive the first suction mechanism 430 and the first paperboard to descend, thereby causing the first paperboard to detach from the first paper tray 200. Then, the control cabinet 910 controls the first drive mechanism 410 to drive the two first lifting mechanisms 420 to move towards each other along the second direction.

[0277] Then, the control cabinet 910 controls the second drive mechanism 510 to drive the two second lifting mechanisms 520 and the two second adsorption mechanisms 530 to move in opposite directions along the second direction, so that the second adsorption mechanism 530 is above the first adsorption mechanism 430; the control cabinet 910 controls the second lifting mechanism 520 to drive the second adsorption mechanism 530 to descend, and / or controls the first lifting mechanism 420 to drive the first adsorption mechanism 430 to descend, so that the second adsorption mechanism 530 contacts the first cardboard on the first adsorption mechanism 430; and controls the second adsorption mechanism 530 to adsorb the first cardboard and the first adsorption mechanism 430 to release the first cardboard; then, by controlling the second lifting mechanism 520 to drive the second adsorption mechanism 530 and the first cardboard to rise and move in opposite directions along the second direction, the first cardboard is conveyed to the bonding position above the conveying mechanism 100.

[0278] During the paper feeding and delivery process of the first cardboard, the control cabinet 910 also controls the third drive mechanism 610 to drive the two third lifting mechanisms 620 and the two third suction mechanisms 630 to move in opposite directions along the first direction; and controls the third suction mechanism 630 to suction the second cardboard through the second paper feeding port; and controls the third lifting mechanism 620 to drive the first suction mechanism 430 and the second cardboard to descend, thereby causing the second cardboard to detach from the second paper tray 300. Then, the control cabinet 910 controls the third drive mechanism 610 to drive the two third lifting mechanisms 620 to move towards each other along the first direction, thereby conveying the second cardboard to the bonding position.

[0279] During the process of the second cardboard moving from the second paper tray 300 to the bonding position along the first direction, the control cabinet 910 also controls the dispensing machine 710 to output adhesive to the glue gun 720, and the glue gun 720 sprays it to both ends of the second cardboard.

[0280] Meanwhile, before the second cardboard moves to the bonding position, the control cabinet 910 also controls the fourth drive mechanism 810 to drive the two support plates 820 to move towards each other in the first direction, so that when the second cardboard moves to the bonding position, part of the second cardboard is located on the support plate 820.

[0281] At the bonding position, the second cardboard is located below the first cardboard. The control cabinet 910 drives the second adsorption mechanism 530 and the first cardboard to descend to contact with and bond with the second cardboard by controlling the first lifting mechanism 520.

[0282] Then, control cabinet 910 controls the second adsorption mechanism 530 and the third adsorption mechanism 630 to release air, thereby causing the second paperboard to detach from the third adsorption mechanism 630 and the first paperboard to detach from the second adsorption mechanism 530. It also controls the paper feeding structure 500 and the second paper picking structure 600 to perform the next paperboard feeding.

[0283] The control cabinet 910 controls the fourth drive mechanism 810 to drive the two support plates 820 to move in opposite directions along the first direction, thereby widening the gap between the two support plates 820 along the first direction, so that the carton board 10 falls from between the two support plates 820 onto the conveying mechanism 100. In this way, the carton board 10 is output from the conveying mechanism 100.

[0284] The gluing machine using this embodiment can achieve a speed of 15 sheets / minute, improving its processing efficiency. Furthermore, the gluing machine of this embodiment produces cartons offline, independently of the packaging machine, which not only reduces the probability of packaging machine failure but also ensures that carton assembly is unaffected by the packaging machine's cycle time.
