Description

Technical Field

[0001] This invention relates to the field of paper box packaging technology, and in particular to an automatic packaging box sealing machine. Background Technology

[0002] Packaging boxes are boxes used to package products. They can be containers used to protect, display, and showcase products. Their main purpose is to protect the products during transportation. In the packaging of certain products, the products need to be individually packaged and then placed together. The main packaging method is box-in-box, where a single product is placed inside an inner box, and multiple inner boxes are placed sequentially inside an outer packaging box, making the packaging more aesthetically pleasing and protective.

[0003] Existing packaging boxes primarily use cardboard as the packaging material. After the cardboard is cut to a certain shape, creases are pre-pressed. For ease of transportation and storage, the cardboard boxes need to be stacked. Before sealing, both ends of the cardboard box are left open to facilitate product placement. During the sealing process, the folded cardboard box needs to be unfolded, and the two openings of the unfolded box are sequentially folded and sealed. During folding, the paper on both sides of the opening is bent and folded inwards, and the paper is secured using tongues or adhesive. When inserting tongues, the tongue paper needs to be inserted into the snap or the opening. Inside the box, a fixed hinge is used. After sealing one end of the box, which completes the bottom sealing action, the product is placed inside the box cavity through the other end of the box. Finally, the other end of the box is sealed, completing the sealing action and the finished product packaging is finished. In the existing process of sealing the box with hinges at both ends, the hinges on the left and right sides of the opening are folded towards the opening, and then the hinges are fixed to achieve the sealing effect. The tongue-and-groove fixing method eliminates the need for glue or tape, thus offering the advantages of convenience and low cost.

[0004] Referring to Chinese invention patent publication number "CN112278423A" entitled "A Paper Box Packaging Machine," the technical solution discloses "a paper box packaging machine. It includes: a first paper box conveyor line, a box opening mechanism, a paper box tail sealing mechanism, a paper box conveying mechanism, a second paper box conveyor line, a product placement station, a third paper box conveyor line, a folding machine, an instruction manual throwing mechanism, a paper box head sealing mechanism, and a labeling mechanism. The above-mentioned paper box packaging machine can automatically seal the paper box through the paper box tail sealing mechanism and the paper box head sealing mechanism. The instruction manual throwing mechanism can automatically put the instruction manual into the paper box. The labeling mechanism can automatically affix labels to the paper box." Although this technical solution can automate the packaging of paper boxes and instruction manuals, it cannot automatically stack multiple inner boxes neatly inside the outer box, resulting in low automation efficiency and limited applicability.

[0005] Therefore, how to automatically stack multiple inner boxes onto an outer box and seal them is a technical problem that engineers need to solve. Summary of the Invention

[0045] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0046] refer to Figures 1 to 15The system includes a feeding plane 1 for supplying inner boxes, an outer box guide strip 2, a bottom-fastening device 3, a sealing device 10, and a pushing device 9. A box-feeding rack 21 for supplying folded outer boxes is located at one end of the outer box guide strip 2, with the bottom-fastening device 3 positioned near the outside of the rack. A transport plane 22 for conveying finished products is located at the other end of the outer box guide strip 2. A box-retrieving device 4 is located directly below the box-feeding rack 21, with the bottom-fastening device 3 positioned near the outside of the box-retrieving device 4. A box-moving device 6 is located outside the bottom-fastening device 3, and an unfolding device 5 for unfolding the folded outer boxes is located between the box-moving device 6 and the bottom-fastening device 3. The folded outer boxes from the box-feeding rack 21 can be retrieved by the box-feeding device 4 and moved to the unfolding device 5. After the outer box is fully unfolded, the bottom-fastening device 3 fastens the unfolded outer box. During this process, the stacking device 7 can feed the outer boxes. After the inner boxes on plane 1 are stacked, they are placed inside the transfer chamber 82. The transfer chamber 82 is moved closer to the pusher 9 by the material conveying device 8. The outer box with the bottom closed is placed closer to the transfer device 6 by the box unfolding device 5. The transfer device 6 drives the outer box with the bottom closed to align with the pusher 9. The pusher 9 pushes the stacked inner boxes inside the transfer chamber 82 into the outer box with the bottom closed. The transfer device 6 then moves the outer box containing the inner boxes to the sealing device 10. The sealing device 10 automatically seals the outer box. After the finished product is sealed, the transfer device 6 moves the finished product to the transport plane 22 for unloading. This invention can realize the automatic placement of boxes within boxes. It can effectively realize the fully automatic stacking and sealing of multiple inner boxes inside the outer box, improving automation efficiency, thereby improving work efficiency and packaging quality.

[0047] In Example 1, to automate the stacking of inner boxes, after the product is packaged inside the inner box, multiple inner boxes need to be neatly stacked and aligned with the subsequent pushing device 9. This facilitates the pushing device 9 in placing the stacked inner boxes into the outer box. In this example: a stacking device 7 is provided at one end of the feeding plane 1, and the pushing device 9 is located near the outside of the stacking device 7. Furthermore, a conveying device 8 is provided outside the stacking device 7. The conveying device 8 includes a linear movement module 81 and a transfer chamber 82, enabling the transfer... The two ends of the transfer chamber 82 are close to the palletizing device 7 and the outer box guide strip 2, respectively. The linear motion module 81 can drive the transfer chamber 82 to move. When the opening of the transfer chamber 82 is aligned with the palletizing device 7, the stacked inner boxes can be transported into the transfer chamber 82 by the palletizing device 7. When the opening of the transfer chamber 82 is aligned with the pushing device 9, the pushing device 9 can push the stacked inner boxes into the outer box. The bottom of the transfer chamber 82 is fixed on the moving slider of the linear motion module 81, so that one end of the linear motion module 81 is close to the outer box of the palletizing device 7. Furthermore, the other end of the linear moving module 81 is positioned close to the outside of the pushing device 9. Both the pushing device 9 and the sealing device 10 are located near the outside of the outer box guide 2. Both the pushing device 9 and the sealing device 10 correspond to the box transfer device 6. The inner boxes can be stacked and placed inside the transfer chamber 82 by the stacking device 7. The pushing device 9 includes a reciprocating moving module 91 and a box-pushing plate 92. The top of the box-pushing plate 92 is positioned on the moving slider of the reciprocating moving module 91, and one side of the box-pushing plate 92 faces the outside of the outer box guide 2. The stacking device 7 can... After the inner boxes on the feeding plane 1 are stacked, they are placed inside the transfer chamber 82. The linear moving module 81 of the conveying device 8 moves the transfer chamber 82 closer to the pushing device 9, so that one end of the transfer chamber 82 is aligned with the box pushing plate 92. When the inlet opening of the outer box is aligned with the other end of the transfer chamber 82, the reciprocating moving module 91 of the pushing device 9 drives the box pushing plate 92 to push the stacked inner boxes of the transfer chamber 82 to the inside of the outer box. This effectively realizes the stacking of multiple inner boxes and places the stacked inner boxes inside the outer box.

[0048] It should be noted that, as Figures 9 to 13 As shown, in order to ensure that the tab at the inlet opening of the outer box does not block the insertion of the stacked inner box, a baffle plate 83 can be provided at the bottom of the transfer chamber 82 near the guide bar 2 of the outer box. When the linear moving module 81 drives the transfer chamber 82 to be between the pushing device 9 and the inlet opening of the outer box, the baffle plate 83 can block the tab of the outer box.

[0049] In this embodiment, it should be further explained that the palletizing device 7 includes a lateral moving module 71 and a lifting moving module 72. The lifting moving module 72 is mounted on the sliding block of the lateral moving module 71. A material-grabbing gripper 73 is provided on the sliding block of the lifting moving module 72. The lateral moving module 71 can be used to control the moving distance of the lifting moving module 72, and the lifting moving module 72 can also be used to control the lifting height of the material-grabbing gripper 73. During the inner box palletizing process, the inner boxes can be sequentially conveyed to the baffle plate assembly 74 via the feeding plane 1, so that both ends of the inner boxes correspond to the gripping surfaces of the material-grabbing gripper 73. At this time, the lifting moving module 72 can drive the material-grabbing gripper 73 to approach the inner box, completing the gripping of the inner box. The position of the picking claw 73 is adjusted by the horizontal moving module 71 so that the inner boxes can be placed side by side inside the picking claw. When the inner boxes are continuously conveyed to the baffle plate group 74 on the feeding plane 1, the lifting moving module 72 can drive the picking claw 73 to rise. The picking claw 73 lifts the holding inner box and then releases it, completing the effect of stacking the inner boxes. Repeat the above actions until the inner boxes are stacked to a certain number. Finally, the picking claw 73 picks up multiple stacked inner boxes and moves them into the transfer chamber 82 for placement. The transfer chamber 82 can keep the multiple stacked inner boxes parallel and move them to the pushing device 9. The pushing device 9 pushes the inner boxes in the transfer chamber 82 to drop them, so that the multiple stacked inner boxes neatly enter the outer box.

[0050] It should be noted that during the stacking process, in order to ensure that the two ends of the inner box are subjected to uniform force, a correction plate can be provided on both fingers of the picking claw 73. This will ensure that the two ends of the inner box remain flush when the picking claw 73 holds the inner box.

[0051] It should also be noted that a baffle plate group 74 corresponding to the picking claw 73 can be provided at one end of the feeding plane 1. The baffle plate group 74 includes two parallel baffle plates. The opposite side of the two baffle plates forms a leveling cavity with the clamping surface of the picking claw 73. The bottom of one baffle plate is close to the feeding plane 1 and has a strip opening for inserting the inner box. When the inner boxes are conveyed to the stacking device 7 in sequence on the feeding plane 1, the multiple inner boxes to be stacked can enter the leveling cavity in sequence through the strip opening, so that the picking claw 73 of the stacking device 7 can perform the clamping and stacking action on the inner boxes. In addition, during the stacking process of the stacking device 7, the baffle plate group 74 can limit the two sides of the inner box to ensure that the two sides of the inner box are flush, so that the inner box can be neatly placed inside the transfer chamber 82.

[0052] In addition to the above explanation, it should be added that, in order to ensure that the inner box will not be severely deformed during the stacking process, cushioning cotton can be provided on the opposite side of the two correction plates of the picking gripper 73. This ensures that when the inner box is clamped and stacked, the cushioning cotton plays a buffering role, thereby preventing the inner box from being severely deformed due to excessive clamping force.

[0053] To further supplement the above description, in order to ensure that the paper at the inlet opening of the outer box does not obstruct the neat entry of the inner box into the outer box when the pushing device 9 pushes the inner box stacked inside the transfer chamber 82 into the outer box, a unfolding mechanism can be provided at the ends of both the reciprocating moving module 91 and the transverse moving module 71. The unfolding mechanism is close to the outer box guide strip 2, and the distance between the two unfolding mechanisms is the same as the distance between the inlet opening of the outer box. The unfolding mechanism includes a driving cylinder and a baffle plate. The power output end of the driving cylinder is hinged to the top of the baffle plate. The driving cylinder can drive the baffle plate to move, so that the baffle plate can drive the side page at the inlet opening of the outer box to move outward. During the pushing process, it can prevent the side page of the inlet opening from moving inward and obstructing the neat entry of the inner box into the outer box.

[0054] It should be noted that a material blocking mechanism can be provided on the feeding plane 1. The material blocking mechanism includes an extension cylinder and a strip-shaped material blocking plate. One end of the strip-shaped material blocking plate is located at the top of the feeding plane 1, and the other end of the strip-shaped material blocking plate is connected to the power output end of the extension cylinder. During the stacking process, the extension cylinder can drive the strip-shaped material blocking plate to block the inner box from continuing to be fed, thereby achieving the function of controlling the number of stacked items.

[0055] In Example 2, to automate the sequential removal of folded outer boxes, ensure the flatness of the folded outer boxes, and automatically unfold the removed folded outer boxes, ensuring that the folded outer boxes can be fully unfolded, in this example: a box feeding rack 21 for supplying folded outer boxes is provided at one end of the outer box guide 2, and the bottom fastening device 3 is located near the outside of the box feeding rack 21. A transport plane 22 for conveying finished products is provided at the other end of the outer box guide 2. A box picking device 4 is provided directly below the box feeding rack 21, and the bottom fastening device 3 is located near the outside of the box picking device 4. A box moving device 6 is provided outside the bottom fastening device 3, and a box unfolding device 5 for unfolding the folded outer boxes is provided between the box moving device 6 and the bottom fastening device 3.

[0056] like Figure 1 and Figure 4As shown, the box-retrieving device 4 includes a linear drive module 41 and a lifting mechanism 42. The lifting mechanism 42 is located on the power output end of the linear drive module 41. A box-retrieving suction plate 43 is provided on the power output end of the lifting mechanism 42, so that one side of the box-retrieving suction plate 43 faces directly below the outer box guide strip 2. The two ends of the linear drive module 41 correspond to the box feeding rack 21 and the bottom fastening device 3, respectively.

[0057] During the outer box retrieval process, the linear drive module 41 can drive the lifting mechanism 42 to be directly below the box feeding rack 21, so that one side of the box retrieval suction plate 43 is aligned with the folded outer box at the bottom of the box feeding rack 21. The lifting mechanism 42 drives the box retrieval suction plate 43 to approach the folded outer box at the bottom of the box feeding rack 21 for adsorption. The lifting mechanism 42 then drives the box retrieval suction plate 43 to descend again, so that the adsorbed folded outer box can contact the top of the outer box guide strip 2. The linear drive module 41 then drives the box retrieval suction plate 43 to move towards the bottom fastening device 3. During the movement, the adsorbed folded outer box can slide along the top of the outer box guide strip 2 to ensure that there is no serious deformation during the removal of the folded outer box. The outer box guide strip 2 can also support the bottom of the folded outer box.

[0058] like Figure 5 As shown, the display box device 5 includes a linear motion module 51 and a lifting cylinder 52. The lifting cylinder 52 is mounted on the moving slider of the linear motion module 51. A connecting plate 53 is provided on the power output end of the lifting cylinder 52. A display box suction plate 54 and a box pushing cylinder 55 are respectively provided on the outside of the connecting plate 53. A box pushing side plate 56 is provided on the power output end of the box pushing cylinder 55, so that the end of the box pushing side plate 56 corresponds to the top of the outer box guide 2 and the end of the box pushing side plate 56 is inclined, so that one side of the display box suction plate 54 faces directly above the outer box guide 2.

[0059] The unfolding action of the folded outer box is as follows: When the linear drive module 41 drives the box-retrieving suction plate 43 to be directly below the unfolding device 5, the unfolding device 5 can move the unfolding suction plate 54 to align with the folded outer box through the moving mechanism of the unfolding device 5, and the lifting cylinder 52 drives the unfolding suction plate 54 to move towards the top of the folded outer box until the unfolding suction plate 54 adsorbs the top page of the folded outer box. Then the lifting cylinder 52 rises again. After rising to a certain height, since the box-retrieving suction plate 43 adsorbs the bottom page of the folded outer box, and the unfolding suction plate 54 adsorbs the top page of the folded outer box, the folded outer box can be unfolded during the rising process of the unfolding suction plate 54 until the unfolding suction plate 54 rises to a certain height, completing the unfolding action of the folded outer box.

[0060] In addition to the above, it should be noted that, to ensure that the folding outer box can be fully unfolded, the power output end of the push-box cylinder 55, which is set outside the connecting plate 53, can be extended. Since the push-box cylinder 55 is equipped with a push-box side plate 56, the end of the push-box side plate 56 corresponds to the top of the outer box guide strip 2. Then, the push-box cylinder 55 can drive the push-box side plate 56 to move towards the outer box guide strip 2. When the unfolding suction plate 54 adsorbs the folding outer box and unfolds it, the push-box side plate 56 can be used to push the side of the unfolded outer box downward to ensure that the folding outer box can be fully unfolded. The end of the push-box side plate 56 can also be set at an angle to prevent the push-box side plate 56 from directly breaking the surface of the outer box during the downward movement.

[0061] It should also be noted that when the folded outer box is fully unfolded, the box-removing suction plate 43 releases its suction and resets, the power output end of the box-pushing cylinder 55 retracts, causing the box-pushing side plate 56 to reset, and then the linear motion module 51 moves the box-unfolding suction plate 54 to directly above the bottom-fastening device 3, thereby aligning the unfolded outer box with the bottom-fastening station. Then, the lifting cylinder 52 moves the box-unfolding suction plate 54 down to approach the bottom-fastening station of the bottom-fastening device 3 until the bottom of the unfolded outer box contacts the outer box guide strip 2 again. At this time, the top of the unfolded outer box can be in the bottom-fastening station, which facilitates the subsequent bottom-fastening action of the bottom-fastening device 3 on the fully unfolded outer box. For the specific bottom-fastening action, please refer to the description in Embodiment 3.

[0062] It is worth noting that, in order to ensure that the paper on the top and bottom sides of the folded outer box can be adsorbed stably, several adsorption through holes can be provided on one side of the box-removing suction plate 43 and one side of the box-spreading suction plate 54. These adsorption through holes can be arranged to form a shape that fits the top and bottom sides of the folded outer box to ensure stable adsorption.

[0063] In Example 3, to automate the bottom-fastening action of the unfolded outer box, when placing the product inside the outer box, the bottom opening of the outer box needs to be fastened to ensure that the inner box will not fall out of the bottom opening when stacked inside the outer box. In this example, the bottom-fastening device 3 includes a fixed vertical plate 31 and a supporting plate 32, with the supporting plate 32 flush with the surface of the outer box guide strip 2. The supporting 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 provided at both ends of the fixed vertical plate 31. Side page pushing components 321 are also provided at both ends of the supporting plate 32. A latching component 323 is provided between the two side page pushing components 321, so that 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 strip 2.

[0064] like Figure 6 and Figure 7As shown, during the bottom sealing process, the pages around the bottom opening of the outer box need to be folded sequentially. The upper page pushing component 311, lower page pushing component 312, and side page pushing component 321 are all equipped with folding cylinders and folding ramps. The folding ramps are positioned on the power output end of the folding cylinders. The folding cylinders drive the folding ramps to move towards the side pages around the bottom opening of the outer box, causing all the side pages around the bottom opening to move into the bottom opening, completing the folding action. During the bottom sealing process, the upper page pushing component 311... The 11 and the lower page pusher 312 simultaneously fold the upper and lower pages of the bottom opening of the outer box, and the page with the bottom opening is folded by one of the side page pushers 321. The end of the bottom opening of the page is extended and protruded outward. The bottom opening of the page is folded by the other side page pusher 321. After the pages around the bottom opening of the outer box are folded in sequence, the latching tongue component 323 latches the page, thus completing the automatic bottom closing action of the outer box.

[0065] It should be noted that before the folding action, the outer box must be fully unfolded. This can be achieved by providing a box-supporting assembly 322 on the support plate 32. The box-supporting assembly 322 is positioned near the outside of the latching tongue assembly 323. The box-supporting assembly 322 includes a box-supporting cylinder and an arc-shaped plate. The arc-shaped plate is positioned on the power output end of the box-supporting cylinder, and the arc-shaped surface of the arc-shaped plate is close to the outside of the outer box guide strip 2. The box-supporting cylinder can drive the arc-shaped plate to be inserted into the outer box through the opening at the bottom of the outer box. During this process, the outer box can be fully unfolded by the arc-shaped plate to facilitate the subsequent bottom-fastening action, inner box placement, and sealing action.

[0066] In the above, it should be noted that the latching assembly 323 includes a latching cylinder and a latching vertical plate. The latching vertical plate is placed on the power output end of the latching cylinder, and the end of the latching vertical plate is 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 latching action is required, the latching cylinder of the latching assembly 323 can drive the latching vertical plate to move towards the extended protruding end of the bottom page, causing the extended protruding end to latch into the inside of the bottom opening. At this time, the push-out cylinder of the latching assembly 323 is reset, so that the extended protruding end of the bottom page abuts against the inner side of the bottom opening, completing the bottom latching action.

[0067] In Example 4, to achieve the alignment of the outer box after the bottom-fastening action, the pushing device 9 and the sealing device 10 are aligned sequentially. This allows the pushing device 9 to automatically place the neatly stacked inner boxes inside the outer box after the bottom-fastening action, and also facilitates the sealing device 10 in sealing the outer box containing the inner boxes. Furthermore, it ensures that the bottom of the outer box does not loosen during the movement of the outer box, placement of the inner box, and sealing process. In this example, a box-moving device 6 is provided. The box-moving device 6 includes a horizontal moving module 61 and a moving plate 62, allowing the horizontal moving module 61 to... One end of the horizontal moving module 61 is close to the display box device 5, and the other end of the horizontal moving module 61 is close to the top of the transport plane 22. The moving plate 62 is placed on the moving slider of the horizontal moving module 61. A baffle mechanism 63 is symmetrically arranged outside the moving plate 62, and a baffle plate 64 is also arranged between the two baffle mechanisms 63. One side of the baffle plate 64 is close to the outside of the outer box guide strip 2. The baffle mechanism 63 includes a top-moving cylinder 631 and a clamping plate 632. The power output end of the top-moving cylinder 631 is hinged to the top of the clamping plate 632. During installation, the horizontal moving module 61 can be horizontally positioned outside the outer box guide strip 2. The moving distance of the moving plate 62 can be controlled by the horizontal moving module 61. When the horizontal moving module 61 moves the moving plate 62 closer to the outer box on the outer box guide strip 2, the outer box on the outer box guide strip 2 is positioned between the two baffle mechanisms 63. The clamping plate 632 can be rotated by the push cylinder 631, so that one side of the two clamping plates 632 faces each other and abuts against the two outer sides of the outer box. The two baffle mechanisms 63 can then be used to move the outer box to the outside. The two sides of the box act as limiters until one side of the two clamping plates 632 faces each other. The opposite sides of the two clamping plates 632 form a clamping surface for clamping the outer box. During the process of the horizontal moving module 61 driving the moving plate 62 to move in the direction of the box transport plane, the outer box can be driven to slide on the outer box guide 2 in the direction of the box transport plane. During the clamping of the outer box, one side of the baffle plate 64 can provide a limiting support for the bottom position of the outer box. When clamping the moving outer box and inserting the inner box into the outer box, it can prevent the bottom paper of the outer box from coming loose.

[0068] During the process of the outer box sliding on the outer box guide strip 2 driven by the box transfer device 6, the outer box can be brought close to the pusher device 9 until the inlet of the outer box is aligned with the transfer chamber 82 on which the stacked inner boxes are placed, and then the movement stops. This allows the pusher device 9 to push the stacked inner boxes on the transfer chamber 82 into the outer box through the inlet of the outer box. After the stacked inner boxes are placed into the outer box, the box transfer device 6 again drives the outer box containing the inner boxes to the sealing device 10 for sealing. The specific sealing action can be referred to in Embodiment 4.

[0069] It should be added that, in order to ensure that the bottom of the outer box can be stably placed on the outer box guide strip 2 when the box transfer device 6 moves the outer box on the outer box guide strip 2, at least two outer box guide strips 2 can be provided, so that the two outer box guide strips 2 are parallel and correspond to the bottom sides of the outer box respectively, so as to stably support the outer box and ensure that the outer box will not fall off.

[0070] Example 5: To automate the sealing process of the outer box containing the inner box, after placing the stacked inner boxes into the outer box, the outer box's inlet opening needs to be sealed. Since the outer box's inlet opening has a tab, the tab needs to be folded during the sealing process, and its front end bent and inserted into the outer box opening so that its front end abuts against the top side of the outer box opening. In this example: Figure 14 and Figure 15 As shown, the sealing device 10 includes a supporting vertical plate 101, a tongue mechanism 102, and a closing mechanism 103. Both the tongue mechanism 102 and the closing mechanism 103 are located outside the supporting vertical plate 101. The tongue mechanism 102 includes a first push cylinder 1021 and a right-angled bend 1022. The right-angled bend 1022 is positioned on the power output end of the first push cylinder 1021, and one end of the right-angled bend 1022 is close to the outer box guide strip 2. The closing mechanism 103... 03 includes a second push cylinder 1031 and a mounting plate 1032. The mounting plate 1032 is mounted on the second push cylinder 1031. Telescopic cylinders 1033 are symmetrically arranged at the bottom of the mounting plate 1032, and each telescopic cylinder 1033 has a hinge block 1034 on its power output end. The bottom of the right-angle bent plate 1022 abuts against the top of the hinge block 1034, and one side of the two hinge blocks 1034 is flush.

[0071] It should be further explained that a sealing mechanism 99 can be provided outside the supporting vertical plate 101. The sealing mechanism 99 is located directly below the tongue insertion mechanism 102. The sealing mechanism 99 includes an ejector cylinder 991 and a sealing plate 992. The sealing plate 992 is also located on the power output end of the ejector cylinder 991, so that one side of the sealing plate 992 faces the outer box guide strip 2.

[0072] In addition to the above description, it is worth noting that a lifting assembly 100 is also provided directly below the sealing mechanism 99. The lifting assembly 100 includes a lifting cylinder 1001 and a lifting ramp 1002. The bottom of the lifting ramp 1002 is located on the power output end of the lifting cylinder 1001, so that the top of the lifting ramp 1002 is located directly below the tongue insertion mechanism 102, and the inclined surface of the lifting ramp 1002 faces the outer box guide strip 2.

[0073] Before the sealing process, the two sides of the feed opening need to be closed. The closing mechanism 103 can move the two sides of the feed opening inward. Then, the pushing component 100 can bring the tongue-shaped paper closer to the feed opening of the outer box. Finally, the tongue-shaped paper can be moved towards the feed opening by the tongue-shaped mechanism 102. Since the bottom of the right-angle bending plate 1022 abuts against the top of the closing inclined block 1034, the right-angle bending plate 1022 can be used to drive the top of the tongue-shaped paper to bend towards the feed opening, thereby completing the tongue action. Finally, the sealing mechanism 99 can be used to completely cover the feed opening with the tongue-shaped paper, so that the top of the tongue-shaped paper can be completely inserted into the inner top side of the feed opening, thus completing the sealing process.

[0074] The lifting cylinder 1001 can drive the lifting inclined plate 1002 to move upward. During the movement, the lifting inclined plate 1002 can drive the tongue paper to move towards the feeding opening of the outer box until one side of the tongue paper completely covers the feeding opening and then stops. The tongue mechanism 102 performs a tongue insertion action on the end of the tongue paper to complete the sealing action.

[0075] To ensure that the lifting ramp 1002 does not obstruct the sealing plate 992 from contacting the tongue paper when it pushes the tongue paper to block the feed opening, a slot can be provided in the center of the lifting ramp 1002. When the lifting ramp 1002 lifts and pushes the tongue paper to block the feed opening, the slot is aligned with one side of the sealing plate 992, which facilitates the sealing plate 992 to press the tongue paper tightly through the slot and complete the final sealing action.
