Currently, for some commodities, especially those used as gifts, the packaging boxes used have a paper inner box and a face paper attached to the surface of the paper inner box to enhance the aesthetic feeling.

[0003] However, when processing and producing such packaging boxes, generally, crease lines are first imprinted on the long strip cardboard on the four sides, and then the frame is formed by surrounding. For example, in the "A Frame Surrounding Machine for Paper Boxes" with the application number 201721927888.9, through the transmission of a conveyor belt in cooperation with a first baffle, a second baffle, a pressing plate, and a hydraulic driving gas, the surrounding plate is turned upwards, so as to accurately fold the crease line of the cardboard surrounding frame. However, it only simply provides the function of surrounding the paper box, its function is too single, and it cannot well adapt to the surrounding frame forming products with face paper attached to the four sides. At the same time, after the cardboard adheres to the face paper and forms the surrounding frame, it is also necessary to carry out shaping and defoaming to eliminate the air bubbles existing between the paper inner box and the leather case. Moreover, the bottom plate also needs to be formed by other equipment;

[0004] Currently, the packaging box processing equipment on the market combines the processing equipment for various processes such as feeding, folding edges, attaching bottom cards, defoaming and forming, gluing, and discharging into a production line, and fails to integrate all processes on the same equipment, resulting in low production efficiency.

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0044] Such as Figure 1-12As shown in the figure, the present invention provides a defoaming and forming device for the bottom plate of a packaging box sticker, including a machine table and a working station turntable 10 provided on the machine table. Around the working station turntable 10, there are provided a hemming assembly 20 for hemming the face paper attached to the surface of the cardboard after forming the surrounding frame, a bottom card pasting assembly 30 for pasting the bottom card to complete the forming of the packaging box, and a defoaming assembly 40 for defoaming the formed packaging box; at least three workpiece trays 11 for carrying workpieces are provided on the working station turntable 10.

[0045] During specific implementation, as Figure 1 shown in the figure, a working station turntable 10 is provided on the machine table, and the working station turntable 10 is driven by a turntable drive mechanism provided below the working station turntable 10 to realize its rotation; the turntable drive mechanism includes a drive motor for providing driving force and a divider for controlling the rotation angle of the working station turntable 10; under the drive of the drive motor and the divider, the rotation angle of the working station turntable 10 each time can be controlled to correspond to the implementation of the equipment in each section around the working station turntable 10.

[0046] In this embodiment, the semi-finished paper box 80 entering the device can be a product as Figure 2 shown in the figure. The cardboard of the semi-finished paper box 80 has completed the four-sided surrounding frame. At the same time, among the attached face papers, the long sides 81 of the face papers on three sides have been completed and attached to the inner wall of the cardboard, while the short sides 82 of the face papers are in a state of being folded inward by 90°, and only the long sides 81 of the face papers on one side remain unfinished and attached to the inner wall of the cardboard.

[0047] The working station turntable 10 is provided with workpiece trays 11, and the workpiece trays 11 are used to carry the cardboard that has completed the four-sided surrounding frame; through the hemming assembly 20, the long sides 81 of the remaining face paper are folded inward to complete the attachment of the face paper to the inner wall of the cardboard.

[0048] Then, through the rotation of the working station turntable 10, it enters the section of the bottom card pasting assembly 30. Since the short sides 82 of the face paper are in a state of being folded inward by 90°, the bottom card can be directly placed into the semi-finished paper box 80 to complete the adhesion. Of course, if it is only a cardboard with a four-sided surrounding frame, the bottom card can be adhered to the cardboard with the surrounding frame formed by coating glue around the bottom card and other methods to realize the forming of the box body.

[0049] Finally, through the defoaming assembly 40 for defoaming the formed packaging box, the bubbles generated during the attachment of the face paper are removed, so as to realize the automatic forming and defoaming of the cardboard and the bottom plate after the surrounding frame is formed.

[0050] As a preferred solution, the hemming assembly 20 includes a positioning mechanism for positioning the cardboard, a flat folding mechanism for flat folding the attached face paper, a folding and attaching mechanism for folding the flat-folded face paper and attaching it to the inner surface of the cardboard, and a hemming drive mechanism for driving the cardboard positioning mechanism, the flat folding mechanism, and the folding and attaching mechanism to move;

[0051] During specific implementation, the incoming materials in the previous section are regularized through the positioning mechanism to facilitate the implementation of hemming. Then, through a flat folding mechanism in sequence, the face paper attached to the cardboard is folded 90° from parallel to the adhered paper surface into the box to be perpendicular to the cardboard. Then, through the folding and attaching mechanism, the face paper is further folded 90° into the box body and squeezed to firmly adhere to the inner surface of the corresponding cardboard.

[0052] Preferably, it further includes a feeding assembly 50 for transporting the semi-finished paper box 80 to the workpiece tray 11.

[0053] In order to further realize the automation of product production, in this exemplary embodiment, the packaging box forming and defoaming device further includes a feeding assembly 50 for transporting the semi-finished paper box 80 to the workpiece tray 11. As Figures 3-4 shown, the feeding assembly 50 is arranged above the station turntable 10 through a bracket, and the semi-finished paper box 80 to be processed is transported to the workpiece tray 11 through a feeding device such as a manipulator or a suction cup, so that it can enter the subsequent process section faster and more accurately;

[0054] Preferably, the feeding assembly 50 includes a cardboard feeding gripper 51 and a cardboard feeding drive mechanism 52 for driving the cardboard feeding gripper 51 to move.

[0055] As a preferred solution, as Figures 3-4 shown, the feeding assembly 50 includes a cardboard feeding gripper 51. The semi-finished paper box 80 can be more stably grasped and transferred to the workpiece tray 11 through the cardboard feeding gripper 51. The cardboard feeding gripper 51 is preferably set to 4. By simultaneously clamping the four corners of the semi-finished paper box 80, stable product transfer is achieved. At the same time, a cardboard feeding drive mechanism 52 is arranged above the cardboard feeding gripper 51 through a bracket. The cardboard feeding drive mechanism 52 includes a servo motor for driving the cardboard feeding gripper 51 to reciprocate between the cardboard supply process and the station turntable 10, and a cylinder for driving the cardboard feeding gripper 51 to move up and down. During actual operation, the grippers of the cardboard feeding gripper 51 are distributed on both sides of the cardboard, and the grippers are controlled to approach to clamp, so as to carry the cardboard to move, so as to realize the transfer of the cardboard into the workpiece tray 11.

[0056] Preferably, the feeding assembly 50 further includes a flipping mechanism 53, which is used to flip the semi-finished paper box 80 conveyed in the previous process, and the flipped semi-finished paper box 80 is transported to the workpiece tray 11 by the cardboard feeding gripper 51.

[0057] As an adaptable solution, as Figures 3-4 shown, the feeding assembly 50 may also be provided with a flipping mechanism 53, which is used to flip the semi-finished paper box 80 conveyed in the previous process, and the flipped semi-finished paper box 80 is transported to the workpiece tray 11 by the cardboard feeding gripper 51. On the one hand, flipping can facilitate the clamping by the cardboard feeding gripper 51. On the other hand, by flipping the product, the subsequent processes can be conveniently implemented.

[0058] Preferably, it further includes a discharging assembly 60 for transporting the packaging box out of the station turntable 10.

[0059] During specific implementation, in order to achieve fully automated production of the entire process, the packaging box forming and defoaming equipment further includes a discharging assembly 60 for transporting the packaging box out of the station turntable 10. The discharging assembly 60 is arranged around the station turntable 10. Through equipment such as a manipulator or a suction cup, the packaging box on the workpiece tray 11 is transported to the discharge port, enabling it to enter the subsequent process faster and more accurately.

[0060] Preferably, the discharging assembly 60 includes a discharging suction cup 61 and a discharging driving mechanism 62 for driving the discharging suction cup 61 to move.

[0061] As a preferred solution, the discharging assembly 60 includes a discharging suction cup 61, which adsorbs the packaging box with the bottom card attached and transfers it to the discharge port. The discharging suction cup 61 is preferably set to 4. By simultaneously adsorbing the product at the four corners, the product can be more stably transported to the discharge port. The discharging driving mechanism 62 includes a servo motor for driving the discharging suction cup 61 to reciprocate between the station turntable 10 and the subsequent process, and a cylinder for driving the discharging suction cup 61 to move up and down. During actual use, the cylinder controls the suction cup to suck the product, thereby enabling the movement of the packaging box to transport the packaging box out of the workpiece tray 11.

[0062] During specific implementation, as an exemplary implementation manner, as Figure 1 and 6 shown, the four sides of the workpiece tray 11 are movable clamping plates 111, preferably set to 4, and the clamping plate driving mechanism 112 can be a cylinder. The cylinder is used to control the movable clamping plates 111 to move back and forth. When discharging is required, the movable clamping plates 111 can move outwards to facilitate the discharging device to pick up the material, etc.

[0063] Preferably, it further includes a gluing assembly 70 for gluing the surface of the bottom board after the bottom board pasting operation is completed.

[0064] During specific implementation, in order to make full use of the space and operation advantages of the station turntable 10, such as Figure 1 and Figure 7 as shown, a gluing assembly 70 is further provided around the station turntable 10. The gluing assembly 70 is used for gluing the surface of the packaging box bottom board after the bottom board pasting operation is completed. The gluing method can be spray gluing, dot gluing, etc. This gluing process is a pre-set process for facilitating the subsequent process of attaching a decorative bottom board inside the paper box.

[0065] Preferably, the bottom card pasting assembly 30 includes a bottom card positioning mechanism 31, a bottom card loading suction cup 32, and a bottom card loading driving mechanism 33 for driving the movement of the bottom card loading suction cup 32;

[0066] The bottom card positioning mechanism 31 includes a positioning push plate 311 and a positioning fixing plate 312, and the positioning push plate 311 is pushed by a cylinder to move.

[0067] During specific implementation, as Figures 8-9 shown, the bottom card pasting assembly 30 includes a bottom card positioning mechanism 31. The bottom card positioning mechanism 31 includes a positioning push plate 311 and a positioning fixing plate 312. By cooperating with the positioning fixing plate 312 and the positioning push plates 311 arranged on the other three sides, the position of the bottom card sent to the bottom card positioning mechanism 31 is positioned, so that the bottom card loading suction cup 32 can place the bottom card more accurately on the cardboard formed by the inner frame of the workpiece tray 11 when sucking and transferring the bottom card, reducing multiple operations or defective products caused by inaccurate placement; among them, the bottom card loading driving mechanism 33 includes a servo motor for driving the bottom card loading suction cup 32 to reciprocate between the station turntable 10 and the bottom card positioning mechanism 31, and a cylinder for driving the bottom card loading suction cup 32 to move up and down. During actual use, the suction cup is controlled by the cylinder to suck the product, so as to realize the movement carrying the bottom card, so as to carry the bottom card out of the bottom card positioning mechanism 31 and place it inside the product on the workpiece tray 11.

[0068] Preferably, the defoaming assembly 40 includes a defoaming mold 41 located above the workpiece tray 11 and a defoaming driving mechanism 42 for driving the defoaming mold 41 to move up and down.

[0069] During specific implementation, the defoaming assembly 40 is used for defoaming the face paper attached to the surface of the packaging box, such as Figures 10-11As shown in the figure, the defoaming assembly 40 includes a defoaming mold 41 and a defoaming driving mechanism 42. The defoaming driving mechanism 42 is arranged above the station turntable 10 through a bracket. The defoaming mold 41 is connected to the output end of the defoaming driving mechanism 42. The defoaming mold 41 is integrally rectangular, and its size is adapted to the size inside the packaging box. Preferably, the defoaming driving mechanism 42 is a cylinder, and the defoaming mold 41 is made of POM material. When the defoaming driving mechanism 42 operates, it can drive the defoaming mold 41 to move up and down.

[0070] Preferably, the defoaming assembly 40 further includes a movable top block 43 arranged below the station turntable 10, and a movable top block driving mechanism 44 for controlling the movable top block 43 to push up the bottom surface of the workpiece tray 11 to cooperate with the defoaming mold 41 to extrude and defoam the product on the workpiece tray 11.

[0071] During specific implementation, as Figures 10-11 shown in the figure, the defoaming assembly 40 further includes a movable top block 43. The movable top block driving mechanism 44 is a double-stroke cylinder. By controlling the movable top block 43 to move upward, after passing through the station turntable 10, it contacts the bottom surface of the workpiece tray 11 and continues to push upward, so as to realize re-extrusion and defoaming of the product in cooperation with the defoaming mold 41, further strengthening the defoaming effect.

[0072] As a preferred solution, as Figures 10-11 shown in the figure, the defoaming assembly 40 includes a fixed platform 45. There is a through hole on the fixed platform 45 for the up and down movement of the movable top block 43. At the same time, two positioning protrusions 451 are arranged on the fixed platform 45. Push cylinders 452 are respectively arranged on the left and right sides below the fixed platform 45. The positioning protrusions 451 are adapted to the positioning grooves arranged below the station turntable 10. During specific implementation, the double-stroke cylinder and the push cylinders 452 are started at the same time. The push cylinders 452 push the fixed platform 45 upward so that the positioning protrusions 451 extend into the positioning grooves, enabling the fixed platform 45 to be aligned with the workpiece tray 11. Then the double-stroke cylinder continues to push the movable top block 43 to push up the bottom plate of the workpiece tray 11 for secondary extrusion and defoaming.

[0073] When the packaging box forming and defoaming equipment provided by the present invention is actually used, the feeding assembly 50 passes through Figure 2After the semi-finished paper box 80 shown is flipped to the appropriate orientation by the flipping mechanism 53, the cardboard loading drive mechanism 52 controls the cardboard loading gripper 51 to clamp the cardboard into the workpiece tray 11 on the station turntable 10. Under the combined action of the turntable drive structure and the divider, the workpiece tray 11 is moved to the next process, i.e., the edge folding assembly 20, through the rotation of the station turntable 10. The edge folding assembly 20 sequentially limits the position of the incoming material through the positioning mechanism, and then, through the flat folding mechanism and the flipping mechanism, the long side 81 of the face paper of the incoming material is attached to the inner wall of the cardboard, thereby forming a four-sided enclosure, and the long sides 81 of the face paper are all attached to the inner wall, while the short side 82 of the face paper is folded inward by 90°; then the station turntable 10 controls to rotate the workpiece tray 11 to the bottom card attaching assembly 30, and the bottom card loading suction cup 32 sucks and transfers the bottom card fixed by the bottom card positioning mechanism 31 into the bottom of the four-sided enclosed cardboard in the workpiece tray 11. Since the short side 82 of the face paper is folded inward by 90°, the bottom card just fits on the sticky side of the short side 82 of the face paper, realizing the combination of the bottom card and the four-sided enclosed cardboard. Then, the station turntable 10 rotates the workpiece tray 11 to the defoaming assembly 40. The defoaming mold 41 on the defoaming assembly 40 is controlled by a cylinder to move downward into the packaged box after the combination of the four-sided cardboard and the bottom card, and is pressed against the side wall of the workpiece tray 11. At the same time, the side wall of the workpiece tray 11 is set to be movable. After the defoaming mold 41 is pressed down, the side wall of the workpiece tray 11, i.e., the movable clamping plate 111, is controlled by a cylinder to press inward. Under the cooperation of the movable clamping plate 111 and the defoaming mold 41, defoaming is realized. Of course, defoaming can also be achieved by pressing upward on the bottom of the workpiece tray 11 to cooperate with the defoaming mold 41 for secondary extrusion defoaming. After defoaming is completed, the station turntable 10 continues to rotate to the gluing assembly 70, and glue is applied to the upper surface of the bottom card by spraying glue or dispensing glue, facilitating the adhesion of the inner decorative material on the bottom surface in the subsequent process section. Finally, through the station turntable 10, it rotates to the unloading assembly 60, and the unloading drive mechanism 62 controls the unloading suction cup 61 to take out the product from the workpiece tray 11 and send it to the subsequent process section.
