Description

Technical Field

[0001] The present invention relates to the technical field of carton packaging, and particularly to an automatic integrated machine for packaging and sealing cartons. Background Art

[0002] A packaging box is a box used to package products. It can be a container for protecting, displaying, and exhibiting products. Its main purpose is to protect the safety of products during transportation. In the packaging process of specific products, the products need to be individually packaged and then placed together. The main packaging method used is the box-in-box method, that is, individual products are placed inside the inner box, and multiple inner boxes are sequentially placed inside the outer packaging box to make the packaging more aesthetic and protective.

[0003] Existing packaging boxes mainly use cardboard as the packaging material. After cutting the cardboard into a certain shape, pre-pressed creases are made. For easy transportation and storage, the carton bodies need to be stacked and placed. Before sealing, both ends of the carton body are left open. After placing the products, during the sealing process of the carton body, the folded carton needs to be unfolded, and the openings at both ends of the unfolded carton body are sequentially folded and sealed. During the folding process, the side papers on both sides of the opening are bent towards the inside of the opening and fixed by inserting tongues or gluing. When inserting the tongue, the tongue paper needs to be inserted into the buckle or the inner side of the opening to fix the folded page. After sealing one end opening of the carton, that is, after completing the bottom buckling action, the product is placed in the carton cavity through the other end opening of the carton, and finally the other end opening of the carton body is sealed. After completing the sealing action, the finished product packaging is completed. During the folding and sealing process of the openings at both ends of the existing carton body, mainly the folding pages on the left and right sides of the opening are folded towards the opening, and then the folding ears are fixed to achieve the sealing effect. The method of fixing with an inserted tongue does not require the use of glue or tape for fixing, and thus has the advantages of convenience and low cost.

[0004] Referring to the Chinese invention patent with the patent announcement number "CN112278423A" and the name "A Carton Packaging Machine", this technical solution discloses "A carton packaging machine, which includes: a first carton conveying line, an opening mechanism, a carton tail-end sealing mechanism, a carton conveying mechanism, a second carton conveying line, a product placement station, a third carton conveying line, a folding machine, an instruction throwing mechanism, a carton head-end sealing mechanism, and a labeling mechanism. The above carton packaging machine can achieve automatic sealing of cartons through the carton tail-end sealing mechanism and the carton head-end sealing mechanism. Through the instruction throwing mechanism, instructions can be automatically placed into the cartons. Through the labeling mechanism, labels can be automatically pasted on the cartons." Although this technical solution can achieve automated packaging of cartons and instructions, it cannot automatically stack multiple inner boxes neatly inside the outer box, with low automation efficiency and a narrow scope of application.

[0005] Therefore, how to automatically stack multiple inner boxes in an outer box and perform packaging is a technical problem that technicians need to solve at present. Summary of the Invention

[0042] The technical solutions of the embodiments of the present application will be described in detail below with reference to the drawings.

[0043] Reference Figures 1 to 15, by providing a feeding plane 1 for supplying inner boxes, an outer box guide bar 2, a bottom buckling device 3, a box sealing device 10 and a pushing device 9; also by providing a box supply rack 21 for supplying folded outer boxes at one end of the outer box guide bar 2, arranging the bottom buckling device 3 outside near the box supply rack 21, providing a transportation plane 22 for transporting finished products at the other end of the outer box guide bar 2, arranging a box picking device 4 directly below the box supply rack 21, arranging the bottom buckling device 3 outside near the box picking device 4, providing a box moving device 6 outside the bottom buckling device 3, and also providing a box unfolding device 5 for unfolding the folded outer box between the box moving device 6 and the bottom buckling device 3. The folded outer box on the box supply rack 21 can be picked up by the box picking device 4 and moved to the box unfolding device 5. After the outer box is fully unfolded, the bottom buckling device 3 performs a bottom buckling action on the unfolded outer box. During this process, the palletizing device 7 can palletize and stack the inner boxes on the feeding plane 1 and place them inside the transfer bin 82. The transfer bin 82 is moved close to the pushing device 9 by the material transporting device 8. The bottom-buckled outer box is placed close to the box moving device 6 again through the box unfolding device 5, and the box moving device 6 drives the bottom-buckled outer box to align with the pushing device 9. The pushing device 9 can push the palletized and stacked inner boxes inside the transfer bin 82 into the bottom-buckled outer box, and the box moving device 6 drives the outer box loaded with the inner box to move to the box sealing device 10 again. The box sealing device 10 performs an automatic box sealing action on the outer box. After the finished product is packaged, the box moving device 6 drives the finished product to move out on the transportation plane 22, and the automatic placement action of the inner box in the outer box can be realized. The present invention can effectively realize the fully automatic integrated action of stacking multiple inner boxes in the outer box and packaging, improve the automation efficiency, and further improve the work efficiency and the packaging quality of the packaging box.

[0044] Embodiment 1. To automatically stack and palletize inner boxes, after the products are packaged inside the inner boxes, multiple inner boxes need to be neatly stacked and palletized, and the stacked inner boxes are moved and aligned with the subsequent pusher device 9, facilitating the pusher device 9 to push the stacked inner boxes into the outer box. In this embodiment: A palletizing device 7 is provided at one end of the feeding plane 1, the pusher device 9 is arranged outside near the palletizing device 7, and a material transporting device 8 is also provided outside the palletizing device 7. The material transporting device 8 includes a linear moving module 81 and a transfer bin body 82, such that both ends of the transfer bin body 82 are respectively close to the palletizing device 7 and the outer box guide bar 2. The transfer bin body 82 can be driven to move by the linear moving module 81. When the opening of the transfer bin body 82 is aligned with the palletizing device 7, the palletizing device 7 can transport the stacked inner boxes into the transfer bin body 82. When the opening of the transfer bin body 82 is aligned with the pusher device 9, the pusher device 9 can push the stacked inner boxes into the outer box. The bottom of the transfer bin body 82 is fixed on the moving slider of the linear moving module 81, one end of the linear moving module 81 is close to the outside of the palletizing device 7, and the other end of the linear moving module 81 is close to the outside of the pusher device 9. Both the pusher device 9 and the box sealing device 10 are arranged outside near the outer box guide bar 2. Both the pusher device 9 and the box sealing device 10 correspond to the box moving device 6. The palletizing device 7 can stack the inner boxes on the feeding plane 1 and then place them inside the transfer bin body 82. The pusher device 9 includes a reciprocating moving module 91 and a box pushing flat plate 92. The top of the box pushing flat plate 92 is arranged on the moving slider of the reciprocating moving module 91, and one side of the box pushing flat plate 92 faces the outside of the outer box guide bar 2. The palletizing device 7 can stack the inner boxes on the feeding plane 1 and then place them inside the transfer bin body 82. The linear moving module 81 of the material transporting device 8 moves the transfer bin body 82 close to the pusher device 9, aligning one end of the transfer bin body 82 with the box pushing flat plate 92. When the feeding opening of the outer box is aligned with the other end of the transfer bin body 82, the reciprocating moving module 91 of the pusher device 9 drives the box pushing flat plate 92 to push the stacked inner boxes in the transfer bin body 82 to translate into the outer box, effectively realizing the stacking and palletizing of multiple inner boxes and placing the stacked and palletized inner boxes inside the outer box.

[0045] It should be noted that as Figures 9 to 13 shown, to ensure that the tongue leaf paper at the feeding opening of the outer box does not block the stacked inner boxes from being placed, a baffle bottom plate 83 can be provided at the bottom of the end of the transfer bin body 82 close to the outer box guide bar 2. When the linear moving module 81 drives the transfer bin body 82 to be between the pusher device 9 and the feeding opening of the outer box, the baffle bottom plate 83 can block the tongue leaf paper of the outer box.

[0046] In this embodiment, it should be supplemented that the stacking device 7 includes a transverse moving module 71 and a lifting and moving module 72. The lifting and moving module 72 is arranged on the moving slider of the transverse moving module 71. By arranging a material picking clamp 73 on the moving slider of the lifting and moving module 72, the transverse moving module 71 can be used to control the moving distance of the lifting and moving module 72, and the lifting and moving module 72 can also be used to control the lifting height of the material picking clamp 73. During the stacking process of the inner boxes, the inner boxes can be transported to the inside of the baffle plate group 74 in sequence through the feeding plane 1, so that the two ends of the inner boxes can correspond to the clamping surfaces of the material picking clamp 73. At this time, the lifting and moving module 72 can be used to drive the material picking clamp 73 to approach the inner box to complete the grabbing of the inner box and The trolley assembly 72 is used to move the inner boxes to the upper and lower surfaces of the packaging, and the packaging is moved to the upper and lower surfaces of the packaging. It is particularly noted that during the palletizing process, in order to ensure that both ends of the inner box are evenly stressed, correction plates can be provided on both clamping fingers of the material taking clamp 73 to ensure that both ends of the inner box remain flush when the inner box is clamped by the material taking clamp 73.

[0047] It should also be noted that a baffle plate group 74 corresponding to the material picking clamp 73 can be provided at one end of the feeding plane 1, and the baffle plate group 74 includes two parallel baffle plates, and the opposite sides of the two baffle plates form a flattening cavity with the clamping surface of the material picking clamp 73, and the bottom of one of the baffle plates is close to the feeding plane 1 and is provided with a strip opening for the inner box to be placed. When the feeding plane 1 transports the inner boxes in sequence to the stacking device 7, multiple inner boxes to be stacked can enter the flattening cavity in sequence through the strip opening, so that the material picking clamp 73 of the stacking device 7 can clamp and stack the inner boxes; and in the process of stacking the inner boxes by the stacking device 7, the baffle plate group 74 can limit the two sides of the outside of the inner box to ensure that the two sides of the inner box are flush, so that the inner boxes can be neatly placed inside the transfer bin 82.

[0048] Regarding the above description, it should also be supplemented that in order to ensure that the inner box will not be severely deformed during the palletizing process, buffer cotton can be provided on the opposite sides of the two correction flat plates of the material-taking gripper 73, so as to ensure that when gripping the inner box for palletizing, the buffer cotton plays a buffering role, thereby preventing the inner box from being severely deformed due to excessive gripping force.

[0049] Regarding the above description, a further supplement is that in order to ensure that when the pushing device 9 pushes the inner boxes stacked inside the transfer bin 82 into the outer box, the end page paper of the feeding opening of the outer box will not block the inner boxes from neatly entering the outer box, a page unfolding mechanism can also be provided at the ends of the reciprocating movement module 91 and the lateral movement module 71, so that the page unfolding mechanism is close to the outer box guide bar 2, and the distance between the two page unfolding mechanisms is the same as the size of the feeding opening spacing of the outer box. The page unfolding mechanism includes a driving cylinder and a page blocking flat plate. The power output end of the driving cylinder is hinged to the top of the page blocking flat plate, and the driving cylinder can be used to drive the page blocking flat plate to move, so that the page blocking flat plate can drive the side pages at the feeding opening of the outer box to move outward. During the pushing process, it can prevent the side pages of the feeding opening from moving toward the inside of the opening and blocking the inner boxes from neatly entering the outer box.

[0050] It should be particularly supplemented that a material blocking mechanism can be provided on the feeding plane 1. The material blocking mechanism includes a protruding cylinder and a strip-shaped material blocking plate member. One end of the strip-shaped material blocking plate member is located at the top of the feeding plane 1, and the other end of the strip-shaped material blocking plate member is connected to the power output end of the protruding cylinder. During the palletizing process, the protruding cylinder can be used to drive the strip-shaped material blocking plate member to block the continuous feeding of the inner boxes, thereby achieving the function of controlling the palletizing quantity.

[0051] In the second embodiment, in order to automatically take out the folded outer boxes in sequence, ensure the flatness of the folded outer boxes, and perform an automatic unfolding action on the folded outer boxes taken out and ensure that the folded outer boxes can be completely unfolded. In this embodiment: a box supply rack 21 for supplying folded outer boxes is provided at one end of the outer box guide bar 2, the bottom closing device 3 is arranged outside near the box supply rack 21, a transportation plane 22 for transporting finished products is provided at the other end of the outer box guide bar 2, a box taking device 4 is provided directly below the box supply rack 21, the bottom closing device 3 is arranged outside near the box taking device 4, a box moving device 6 is arranged outside the bottom closing device 3, and a box unfolding device 5 for unfolding the folded outer boxes is arranged between the box moving device 6 and the bottom closing device 3; As Figure 1 and Figure 4As shown in the figure, the box taking device 4 includes a linear drive module 41 and a lifting mechanism 42. The lifting mechanism 42 is arranged at the power output end of the linear drive module 41. By providing a box taking suction plate 43 at the power output end of the lifting mechanism 42, one side of the box taking suction plate 43 faces directly below the outer box guide bar 2. Also, both ends of the linear drive module 41 respectively correspond to the box supply rack 21 and the bottom buckling device 3; During the process of taking the outer box, the linear drive module 41 can drive the lifting mechanism 42 to be directly below the box supply rack 21, align one side of the box taking suction plate 43 with the folded outer box at the bottom of the box supply rack 21, and drive the box taking suction plate 43 to approach the folded outer box at the bottom of the box supply rack 21 for adsorption through the lifting mechanism 42. Then, drive the box taking suction plate 43 to descend again through the lifting mechanism 42, so that the adsorbed folded outer box can contact the top of the outer box guide bar 2. Then, drive the box taking suction plate 43 to move towards the bottom buckling device 3 again through the linear drive module 41. During the movement, the adsorbed folded outer box can slide along the top of the outer box guide bar 2, ensuring that the folded outer box will not be severely deformed during the process of taking out the material, and the outer box guide bar 2 can play a supporting role for the bottom of the folded outer box.

[0052] As Figure 5 shown in the figure, the box unfolding device 5 includes a linear motion module 51 and a lifting cylinder 52. The lifting cylinder 52 is arranged on the moving slider of the linear motion module 51. By providing a connecting plate member 53 at the power output end of the lifting cylinder 52, and respectively providing a box unfolding suction plate 54 and a box pushing cylinder 55 outside the connecting plate member 53, and providing a box pushing side plate 56 at the power output end of the box pushing cylinder 55, the end of the box pushing side plate 56 corresponds to the top of the outer box guide bar 2, and the end of the box pushing side plate 56 is inclined. One side of the box unfolding suction plate 54 faces directly above the outer box guide bar 2; The unfolding action of the folded outer box is as follows: When the linear drive module 41 drives the box taking suction plate 43 to be directly below the box unfolding device 5, the box unfolding device 5 moving mechanism can drive the box unfolding suction plate 54 to align with the folded outer box, and drive the box unfolding suction plate 54 to move towards the top of the folded outer box through the lifting cylinder 52. Until the box unfolding suction plate 54 adsorbs the top sheet of the folded outer box, the lifting cylinder 52 rises again. After rising to a certain height, since the box taking suction plate 43 adsorbs the bottom sheet of the folded outer box and the box unfolding suction plate 54 adsorbs the top sheet of the folded outer box, during the rising process of the box unfolding suction plate 54, it can drive the folded outer box to perform the unfolding work until the box unfolding suction plate 54 rises to a certain height, and the unfolding action of the folded outer box is completed.

[0053] Regarding the above, it should be added that to ensure that the folding outer box can be fully unfolded, the power output end of the box-pushing cylinder 55 arranged outside the connecting plate member 53 can be extended. Since the box-pushing side plate 56 is arranged on the power output end of the box-pushing cylinder 55, the end of the box-pushing side plate 56 corresponds to the top of the outer box guide bar 2. Then, the box-pushing side plate 56 can be driven by the box-pushing cylinder 55 to move towards the outer box guide bar 2. When the box-unfolding suction plate 54 adsorbs the folding outer box for unfolding, the side of the unfolded outer box can be pushed downward by the box-pushing side plate 56 to ensure that the folding outer box can be fully unfolded. The end of the box-pushing side plate 56 can also be arranged obliquely to prevent the situation that the box-pushing side plate 56 directly pierces the surface of the outer box during the downward movement.

[0054] It should also be added that after the folding outer box is fully unfolded, at this time, the box-taking suction plate 43 cancels adsorption and resets. The power output end of the box-pushing cylinder 55 retracts to drive the box-pushing side plate 56 to reset, and the linear motion module 51 drives the box-unfolding suction plate 54 to move above the bottom-closing device 3 again. Then, the unfolded outer box can be driven to align with the bottom-closing station, and the lifting cylinder 52 drives the box-unfolding suction plate 54 to descend close to the bottom-closing station of the bottom-closing device 3 until the bottom of the unfolded outer box touches the outer box guide bar 2 again. At this time, the top of the outer box of the box-unfolding outer box can be at the bottom-closing station, which is convenient for the subsequent bottom-closing device 3 to perform the bottom-closing action on the fully unfolded outer box. The specific bottom-closing action can refer to the description in Embodiment III.

[0055] It should be particularly added that to ensure stable adsorption of the upper and lower paper sheets of the folding outer box, a number of adsorption through holes can be arranged on one side of the box-taking suction plate 43 and one side of the box-unfolding suction plate 54, and the number of adsorption through holes can be surrounded to form a shape adapted to the upper and lower surfaces of the folding outer box to ensure stable adsorption.

[0056] Embodiment III: To automatically perform the bottom-closing action on the bottom of the unfolded outer box, when placing the product into the outer box, the bottom opening of the outer box needs to be bottom-closed to ensure that when the inner boxes are stacked and placed inside the outer box, the inner boxes will not fall out from the bottom opening. In this embodiment: The bottom-closing device 3 includes a fixed vertical plate 31 and a supporting flat plate 32, making the supporting flat plate 32 flush with the surface of the outer box guide bar 2. The supporting flat plate 32 is located at the center of the fixed vertical plate 31. An upper page pushing component 311 and a lower page pushing component 312 are respectively arranged at both ends of the fixed vertical plate 31. Side page pushing components 321 are arranged at both ends of the supporting flat plate 32, and a buckle tongue component 323 is arranged between the two side page pushing components 321. The upper page pushing component 311, the lower page pushing component 312, and the side page pushing component 321 all face the outer box guide bar 2; Such as Figure 6 and Figure 7As shown, when the back is sealed, the pages around the bottom opening of the outer box need to be folded in sequence. The upper page pushing component 311, the lower page pushing component 312 and the side page pushing component 321 can be provided with a folding cylinder and a folding inclined plate. The folding inclined plate is arranged on the power output end of the folding cylinder. The folding inclined plate can be driven by the folding cylinder to move toward the side pages of the bottom opening of the outer box, so that the side pages around the bottom opening of the outer box are moved toward the bottom opening of the outer box to complete the folding action. In the process of sealing the back, the upper page pushing component 311, the lower page pushing component 312 and the side page pushing component 321 can be provided with a folding cylinder and a folding inclined plate. The folding inclined plate is arranged on the power output end of the folding cylinder. The folding inclined plate can be driven by the folding cylinder to move toward the side pages of the bottom opening of the outer box, so that the side pages around the bottom opening of the outer box are moved toward the bottom opening of the outer box to complete the folding action. 11 and the lower page pushing assembly 312 fold the upper and lower side pages of the bottom opening of the outer box synchronously, and fold the pages of paper with a buckled bottom opening through one of the side page pushing assemblies 321, the end of the buckled bottom page of paper is extended and convex, and the buckled bottom page of paper is folded through another side page pushing assembly 321. After the pages of paper around the bottom opening of the outer box are folded in sequence, the buckle tongue assembly 323 performs the buckle tongue action to complete the automatic buckle bottom action of the outer box.

[0057] It should be noted that before the folding action, it is necessary to ensure that the outer box is in a fully expanded state. A box supporting assembly 322 is also provided on the supporting plate 32. The box supporting assembly 322 is arranged outside the buckle tongue assembly 323. The box supporting assembly 322 includes a box supporting cylinder and an arc-shaped plate. The arc-shaped plate is arranged on the power output end of the box supporting cylinder. The arc-shaped surface of the arc-shaped plate is close to the outside of the outer box guide strip 2. The arc-shaped plate can be driven by the box supporting cylinder to be placed into the outer box through the opening at the bottom of the outer box. In this process, the outer box can be fully opened by the arc-shaped plate to facilitate the subsequent bottom buckling action, inner box placement and box sealing action of the outer box.

[0058] In the above, it should be noted that the tongue-locking assembly 323 includes a tongue-locking cylinder and a tongue-locking vertical plate. The tongue-locking vertical plate is arranged on the power output end of the tongue-locking cylinder, and the end of the tongue-locking vertical plate is also placed close to the outer box guide strip 2. After the pages around the bottom opening of the outer box are folded in sequence, when the tongue-locking action is required, the tongue-locking cylinder of the tongue-locking assembly 323 can drive the tongue-locking vertical plate to move toward the extended outer convex end of the bottom page paper, and drive the extended outer convex end to buckle into the interior of the bottom opening. At this time, the pushing cylinder of the tongue-locking assembly 323 is reset, so that the extended outer convex end of the bottom page paper is abutted against the inner side surface of the bottom opening, thereby completing the bottom buckling action.

[0059] Embodiment 4: The outer box that realizes the bottom buckling action during movement is aligned with the pushing device 9 and the box sealing device 10 in sequence, so as to facilitate the pushing device 9 to automatically place the neatly stacked inner boxes inside the outer box with the bottom buckling completed, and also facilitate the box sealing device 10 to perform the packaging action on the outer box loaded with the inner box, and ensure that the bottom of the outer box will not become loose during the processes of moving the outer box, placing the inner box, and sealing the box. In this embodiment: A box moving device 6 is provided. The box moving device 6 includes a horizontal moving module 61 and a moving flat plate 62. One end of the horizontal moving module 61 is close to the box unfolding device 5, and the other end of the horizontal moving module 61 is close to directly above the transportation plane 22. The moving flat plate 62 is arranged on the moving slider of the horizontal moving module 61. By symmetrically arranging a baffle mechanism 63 outside the moving flat plate 62, a box baffle bent plate 64 is further arranged between the two baffle mechanisms 63. One side of the box baffle bent plate 64 is close to the outside of the outer box guide bar 2. The baffle mechanism 63 includes a jacking cylinder 631 and a clamping flat plate 632. The power output end of the jacking cylinder 631 is hinged to the top of the clamping flat plate 632. During installation, the horizontal moving module 61 can be horizontally arranged outside the outer box guide bar 2, and the moving distance of the moving flat plate 62 can be controlled by the horizontal moving module 61. When the horizontal moving module 61 drives the moving flat plate 62 to approach the outer box on the outer box guide bar 2, the outer box on the outer box guide bar 2 is located between the two baffle mechanisms 63. The jacking cylinder 631 can be driven to drive the clamping flat plate 632 to rotate, so that one side of the two clamping flat plates 632 faces each other, and one side of the clamping flat plate 632 abuts against the outer sides of the outer box. The two baffle mechanisms 63 can play a limiting role on both sides of the outer box. Until one side of the two clamping flat plates 632 faces each other, the opposite side of the two clamping flat plates 632 forms a clamping surface for clamping the outer box. During the process of the horizontal moving module 61 driving the moving flat plate 62 to move towards the box transportation plane direction, the outer box can be driven to slide on the outer box guide bar 2 towards the box transportation plane direction. During the process of clamping the outer box, the bottom buckling position of the outer box can be limited and supported by one side of the box baffle bent plate 64. When clamping and moving the outer box and placing the inner box into the outer box, the situation where the bottom buckling page paper of the outer box becomes loose can be prevented; During the process of the box moving device 6 driving the outer box to slide on the outer box guide bar 2, the outer box can be made to approach the pushing device 9 until the feeding port of the outer box is aligned with the transfer bin body 82 where the palletized inner boxes are placed, and then the movement stops, so as to facilitate the pushing device 9 to push the palletized inner boxes on the transfer bin body 82 into the outer box through the feeding opening of the outer box. After the action of placing the palletized inner boxes into the outer box is completed, the box moving device 6 drives the outer box loaded with the inner box to the box sealing device 10 again for the box sealing action. The specific box sealing action can refer to Embodiment 4.

[0060] It should be added that to ensure that when the box transfer device 6 drives the outer box to slide on the outer box guide bar 2, the bottom of the outer box can be stably positioned on the outer box guide bar 2, at least two outer box guide bars 2 can be provided. The two outer box guide bars 2 are made flush with each other, and the two outer box guide bars 2 respectively correspond to both sides of the bottom of the outer box, so as to achieve stable support for the outer box and ensure that the outer box will not fall.

[0061] Embodiment 5. To realize the automatic sealing operation of the outer box loaded with the inner box, after placing the stacked and palletized inner boxes into the outer box, the feeding opening of the outer box needs to be sealed. Since the feeding opening of the outer box is provided with a tongue inserting page paper, during the sealing process, the tongue inserting page paper needs to be folded, and the front end of the tongue inserting page paper is bent and inserted into the inside of the outer box opening, so that its front end abuts against the inner top side of the outer box opening. In this embodiment: As Figure 14 and Figure 15 shown, the box sealing device 10 includes a supporting vertical plate 101, a tongue inserting mechanism 102 and a page closing mechanism 103. The tongue inserting mechanism 102 and the page closing mechanism 103 are both arranged outside the supporting vertical plate 101. The tongue inserting mechanism 102 includes a first pushing cylinder 1021 and a right-angled bent plate 1022. The right-angled bent plate 1022 is arranged on the power output end of the first pushing cylinder 1021, and one end of the right-angled bent plate 1022 is close to the outer box guide bar 2. The page closing mechanism 103 includes a second pushing cylinder 1031 and a mounting plate member 1032. The mounting plate member 1032 is arranged on the second pushing cylinder 1031. By symmetrically arranging telescopic cylinders 1033 at the bottom of the mounting plate member 1032, page closing inclined blocks 1034 are arranged on the power output ends of the two telescopic cylinders 1033. The bottom of the right-angled bent plate 1022 abuts against the top of the page closing inclined blocks 1034, and one side of the two page closing inclined blocks 1034 is flush. It should be further explained that a sealing mechanism 99 can be arranged outside the supporting vertical plate 101. The sealing mechanism 99 is located directly below the tongue inserting mechanism 102. The sealing mechanism 99 includes a jacking cylinder 991 and a sealing flat plate 992. The sealing flat plate 992 is also arranged on the power output end of the jacking cylinder 991, and one side of the sealing flat plate 992 faces the outer box guide bar 2.

[0062] In particular, it should be added that a lifting assembly 100 is also arranged directly below the sealing mechanism 99. The lifting assembly 100 includes a lifting cylinder 1001 and a lifting inclined plate 1002. The bottom of the lifting inclined plate 1002 is arranged on the power output end of the lifting cylinder 1001. The top of the lifting inclined plate 1002 is located directly below the tongue inserting mechanism 102, and the inclined surface of the lifting inclined plate 1002 faces the outer box guide bar 2.

[0063] Before the carton sealing process, the two side papers of the feeding opening need to be closed. The closing mechanism 103 can be used to move the two side papers towards the inside of the feeding opening. Then, the pushing and lifting assembly 100 can be used to move the tongue paper closer to the feeding opening of the outer carton. Finally, the tongue mechanism 102 can be used to move the top end of the tongue paper towards the feeding opening. Since the bottom of the right-angle bent plate 1022 abuts against the top of the closing inclined block 1034, the top end of the tongue paper can be bent towards the feeding opening by driving the right-angle bent plate 1022, thus completing the tongue insertion action. Finally, the sealing mechanism 99 drives the tongue paper to completely block the feeding opening, so that the top end of the tongue paper completely enters the inner top side of the feeding opening, completing the carton sealing action; The pushing and lifting cylinder 1001 can be used to drive the lifting inclined plate 1002 to move upward. During the movement, the lifting inclined plate 1002 can be used to drive the tongue paper towards the feeding opening of the outer carton until one side of the tongue paper completely blocks the feeding opening and then stops. Cooperating with the tongue mechanism 102 to perform the tongue insertion action on the end of the tongue paper, the sealing action is completed; To ensure that when the lifting inclined plate 1002 drives the tongue paper to block the feeding opening, the lifting inclined plate 1002 will not block the sealing flat plate 992 from contacting the tongue paper, a notch can be opened at the center of the lifting inclined plate 1002. When the lifting inclined plate 1002 lifts and pushes the tongue paper to block the feeding opening, the notch corresponds to one side of the sealing flat plate 992, thus facilitating the sealing flat plate 992 to press tightly against the tongue paper through the notch to complete the final sealing action.
