Description

Technical Field

[0001] The present invention relates to the technical field of packaging equipment, in particular to a cartoning machine. Background Art

[0002] In the prior art, for the packaging of snacks in small packets, it is usually necessary to use a packaging box for packaging. The above-mentioned packaging box is usually sealed in the form of a lower snap bottom and an upper inserted box. For the existing packaging boxes for sub-packaged snacks, the main cover of the upper inserted box is usually connected to the long side of the packaging box. Therefore, the current cartoning machine usually uses a push rod to push the main cover from bottom to top, and cooperates with other tongue folding structures to perform the box insertion process on the main cover. The above-mentioned box insertion process structure for the main cover is not applicable to the packaging box in which the main cover is connected to the short side of the packaging box. Since the long side of the main cover is relatively long, when the push rod is pushed upward, the main cover will be greatly bent, so that the tongue folding structure cannot fold the tongue well, resulting in poor processing ability of the cartoning machine for the packaging box in which the main cover is connected to the short side of the packaging box, and it is easy to cause phenomena such as box insertion failure of the packaging box. Summary of the Invention

Detailed implementation mode

[0052] The concept, specific structure and technical effects of the present invention will be clearly and completely described below in conjunction with the embodiments and the drawings, so as to fully understand the purpose, features and effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative efforts shall fall within the scope of protection of the present invention. In addition, all the connection / linkage relationships mentioned in the text do not simply refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the present invention can be combined interactively without conflicting with each other.

[0053] Referring to Figures 1 to 15 , the cartoning machine includes a frame 100, a packaging box placement rack 200, an opening mechanism 300, a cartoning machine inserting box assembly 500, a product transportation line 700 and a loading mechanism 800.

[0054] The cartoning machine has a processing direction, and the packaging box is driven to move along the processing direction. During the movement in the processing direction, different actions (such as bottom buckling, box inserting, product loading, etc.) will be performed when staying at multiple workstations.

[0055] Specifically, the cartoning machine is provided with an opening workstation, a flap folding workstation, a main cover folding workstation and a main cover tongue inserting workstation arranged in sequence along the processing direction.

[0056] The opening mechanism 300 is correspondingly arranged with the opening workstation. The opening mechanism 300 is provided with a packaging box placement area. After the packaging box is placed in the packaging box placement area, the opening mechanism 300 will perform the opening step to open the packaging box.

[0057] The packaging box placement rack 200 is arranged above the packaging box placement area (here, the above does not mean that the packaging box placement rack 200 is arranged directly above the packaging box placement area, but refers to the relative position of the packaging box placement rack 200 and the packaging box placement area in the vertical direction. The position relationship of each component below with respect to the packaging box placement area is also understood in the above way). The lower end of the packaging box placement rack 200 is provided with an opening for taking out the folded packaging box.

[0058] The unpacking mechanism 300 includes a second suction cup assembly 320 and a first suction cup assembly 310. The second suction cup assembly 320 and the first suction cup assembly 310 are arranged in the vertical direction. And the second suction cup assembly 320 and the first suction cup assembly 310 are respectively arranged on the upper and lower sides of the packaging box placement area (in other embodiments, according to the specific layout requirements of the case packing machine, the second suction cup assembly 320 and the first suction cup assembly 310 can also be respectively arranged on the left and right sides of the packaging box placement area). The first suction cup assembly 310 is arranged on the upper side of the second suction cup assembly 320. The second suction cup assembly 320 is arranged on the lower side of the packaging box placement rack 200.

[0059] The first suction cup assembly 310 includes a swing assembly, an adjustment structure 314 and a first suction cup structure 317. The swing assembly is provided with a swing shaft. The first suction cup structure 317 includes four suction cups arranged in a rectangle (in other embodiments, it may also include five, six, two, three or other numbers of suction cups, which can be set by those skilled in the art according to actual needs). The first suction cup structure 317 is fixedly installed on the adjustment structure 314. The first suction cup structure 317 and the adjustment structure 314 move in an arc around the swing shaft, and the first suction cup structure 317 always faces the packaging box placement area. Specifically, the swing assembly includes two first swing rods 311 arranged in parallel with each other (in other embodiments, the number of the first swing rods 311 can also be set to three, four or other numbers, and the specific number of the first swing rods 311 can be designed by those skilled in the art according to actual needs). One end of the first swing rod 311 is hinged to the frame 100, and the other end is hinged with a connecting member 313. The ends of the two first swing rods 311 are connected through the connecting member 313. The distances from the hinged ends of the two first swing rods 311 to the connecting member 313 are the same. By such setting, the two first swing rods 311 and a connecting member 313 form a parallelogram motion mechanism, so that the connecting member 313 can maintain the same posture and move in translation along an arc. One end of one of the first swing rods 311 connected to the frame 100 is connected to a swing driving device. The swing driving device is set as a rotating motor (in other embodiments, the swing driving device can also be set as a conventional rotating driving structure and component such as a rotating cylinder). A strip hole 312 is formed in the first swing rod 311.

[0060] The adjusting structure 314 includes an adjusting seat 315 and two hinge members 316. The number of the hinge members 316 is set to two, and both hinge members 316 are rotatably connected to the adjusting seat 315. The two hinge members 316 are respectively arranged corresponding to the two first swing rods 311. The hinge member 316 is provided with a guide groove 318, and the guide groove 318 is a linear groove body. The first swing rod 311 passes through the guide groove 318, and the first swing rod 311 is slidably connected to the guide groove 318. The cooperation between the guide groove 318 and the first swing rod 311 is used to guide the adjusting structure 314, so that the adjusting structure 314 can only slide along the side of the quadrilateral motion mechanism, so that the quadrilateral motion structure can maintain a quadrilateral to meet the characteristic requirements that the adjusting structure 314 needs to translate along an arc.

[0061] The hinge member 316 is connected with an adjusting member 319. The adjusting member 319 is set as a screw (in other embodiments, a member locked by pressing can also be used to replace the screw). The adjusting member 319 passes through the strip-shaped hole 312 on the first swing rod 311, and the adjusting member 319 is slidably connected to the strip-shaped hole 312. The tail of the adjusting member 319 is threadedly connected to the hinge member 316, and a rotating head is fixedly connected to the head of the adjusting member 319. The end face of the rotating head abuts against the end face of the first swing rod 311 to realize the locking of the adjusting seat 315 and the first swing rod 311, so as to fix the swing radius of the first suction cup assembly 310, so as to adapt to different sizes of packaging boxes.

[0062] In other embodiments, a single first swing rod 311 can also be used, and two gears are arranged at both ends of the first swing rod 311, and the two gears are linked by a gear belt to replace the parallelogram motion mechanism. The gear at one end of the first swing rod 311 is relatively fixed to the frame 100, and the gear at the other end of the first swing rod 311 is relatively fixed to the connecting member 313. When the first swing rod 311 is driven by a swing driving device to rotate, the gear relatively fixed to the frame 100 does not move, and one end of the first swing rod 311 rotates around the swing axis, so that the connecting member 313 relatively fixed to the connecting member 313 rotates relative to the first swing rod 311, so that the connecting member 313 makes an arc translation motion around the swing axis while maintaining a certain posture, so as to keep the first suction cup structure 317 always facing the packaging box placement area. And those skilled in the art can additionally add an adjusting structure 314 to the first swing rod 311 to adapt to the adjustable requirements.

[0063] An adsorption linear drive device and an adsorption sliding guiding structure 321 are provided between the second suction cup assembly 320 and the frame 100. The adsorption linear drive device drives the second suction cup assembly 320 to move in the processing direction. The adsorption linear drive device is set as a combination of a conveyor belt, a drive motor, and a gear (in other embodiments, a conventional linear drive device such as a linear cylinder or a linear motor can also be used). The adsorption linear drive device is used to enable the second suction cup assembly 320 to move back and forth below the packaging box placement rack 200 and below the first suction cup assembly 310, so as to move the packaging box from the packaging box placement rack 200 to the first suction cup assembly 310. The adsorption sliding guiding structure 321 (it should be understood that the adsorption sliding guiding structure 321 includes a guide rail structure and a sliding seat structure, and the guide rail structure and the sliding seat structure are respectively fixedly connected to the frame 100 and the second suction cup assembly 320) is used to guide the second suction cup assembly 320 to slide linearly, and the adsorption sliding guiding structure 321 can play a role in reducing the friction when the second suction cup assembly 320 moves.

[0064] The second suction cup assembly 320 includes a second box-taking driving member 322 and a second suction cup structure 323. The second box-taking driving member 322 is set as a linear cylinder (in other embodiments, the second box-taking driving member 322 can also be set as a conventional linear drive structure or component such as a linear cylinder). The second box-taking driving member 322 drives the second suction cup structure 323 to move in the up and down direction, so as to make the second suction cup structure 323 approach or move away from the packaging box placement rack 200 to realize the taking out of the packaging box.

[0065] The second suction cup structure 323 includes a secondary suction cup 325 and a main suction cup 324 (the secondary suction cup 325 and the main suction cup 324 are respectively Figure 5 the parts indicated by the two dashed boxes in). The secondary suction cup 325 and the main suction cup 324 are arranged in the processing direction. The secondary suction cup 325 and the main suction cup 324 are respectively used for vacuum-sucking two adjacent faces of the packaging box. The secondary suction cup 325 and the main suction cup 324 are respectively controlled by two groups of air sources. The two groups of air sources are independent of each other, so that the main suction cup 324 and the secondary suction cup 325 can be controlled separately. The end face of the packaging box adsorbed by the main suction cup 324 and the end face of the packaging box adsorbed by the first suction cup structure 317 are two relatively arranged end faces.

[0066] When picking up the box, the second box-picking driving member 322 drives the second suction cup structure 323 to approach the packaging box placement rack 200. Subsequently, the main suction cup 324 and the auxiliary suction cup 325 work simultaneously to suck the folded packaging box. After sucking the packaging box, the second box-picking driving member 322 drives the second suction cup structure 323 away from the packaging box placement rack 200. Subsequently, the adsorption linear driving device drives the second suction cup assembly 320 to move along the processing direction, so that the packaging box enters the packaging box placement area. After the packaging box enters the packaging box placement area, the first suction cup structure 317 and the second suction cup structure 323 respectively adsorb different end faces of the packaging box, and are ready to open the packaging box. When opening the box, the main suction cup 324 and the first suction cup structure 317 adsorb the two end faces of the packaging box, and the auxiliary suction cup 325 does not work, so as to avoid damage to the packaging box during the opening and closing process caused by the simultaneous work of the auxiliary suction cup 325.

[0067] The machine frame 100 is further provided with a guiding member 101. The guiding member 101 is set as a rod-shaped member, and the guiding member 101 is gradually inclined upward near the packaging box placement area. The guiding member 101 is used to guide the packaging box to prevent the end of the packaging box from bending downward due to its own gravity, and to prevent the situation that the bent packaging box contacts other structures of the machine frame 100 when entering the packaging box placement area, resulting in damage to the packaging box.

[0068] The product transportation line 700 includes a first transportation line 710, a second transportation line 720 and a product transportation mold 730. The transportation directions of the first transportation line 710 and the second transportation line 720 are perpendicular to each other. The transportation direction of the second transportation line 720 is parallel to the processing direction. The first transportation line 710 is arranged on one side of the second transportation line 720 away from the box-opening mechanism 300. The first transportation line 710 is set as a conventional belt conveyor line. The product transportation mold 730 is set as a "C"-shaped structure to prevent the stacked products from collapsing. The number of product transportation molds 730 is multiple, and multiple product transportation molds 730 are evenly installed on the second transportation line 720. The second transportation line 720 drives multiple product transportation molds 730 to move in a cycle through a conveyor belt.

[0069] The loading mechanism 800 includes a loading horizontal driving device 810, a loading vertical driving device 820, a pushing mounting frame 830, and a loading pushing assembly 840. The loading horizontal driving device 810 is fixedly installed on the machine frame 100. The loading horizontal driving device 810 is set as a driving structure that drives the slide by a belt. The pushing mounting frame 830 is fixedly connected to the slide of the loading horizontal driving device 810. And a guide rail and a guide rail seat are also provided between the pushing mounting frame 830 and the machine frame 100 to guide the pushing mounting frame 830. The loading vertical driving device 820 is fixedly installed at the lower end of the pushing mounting frame 830. The loading vertical driving device 820 is set as a linear cylinder (in other embodiments, the loading vertical driving device 820 can also be set as a linear motor). The loading pushing assembly 840 is installed at the driving end of the loading vertical driving device 820. The loading vertical driving device 820 drives the loading pushing assembly 840 to move up and down in the vertical direction. The loading pushing assembly 840 includes a loading pushing frame 841 and a loading pushing member 842. The loading pushing frame 841 is fixedly connected to the driving end of the loading vertical driving device 820. The loading pushing member 842 is arranged in an L shape, and the opening of the loading pushing member 842 faces downward. The loading pushing member 842 is slidably connected to the loading pushing frame 841. And the loading pushing member 842 is arranged on the side of the loading pushing frame 841 close to the cartridge inserting assembly 500 of the cartoning machine. A spring is provided between the loading pushing member 842 and the loading pushing frame 841. The spring makes the loading pushing member 842 always have a tendency to move away from the loading pushing frame 841. The spring is used to prevent the loading pushing member 842 from flattening the product.

[0070] The cartoning machine further includes a lifting and discharging assembly 910 and a front baffle assembly 920.

[0071] The lifting and discharging assembly 910 includes a lifting and discharging side baffle 911, a lifting and discharging member 912, and a lifting and discharging driving member 913.

The lifting and discharging member 912 is set as a plate-shaped member. The lifting and discharging member 912 is used to support the product. After a group of products are pushed by the loading pushing member 842 to the lifting and discharging member 912, the lifting and discharging driving member 913 drives the lifting and discharging member 912 to move downward. Then another group of products are pushed by the loading pushing member 842 above the lifting and discharging member 912 to realize the stacking of the products. When the products are stacked a certain number of times to meet the number of products to be cartoned, the lifting and discharging driving member 913 drives the lifting and discharging member 912 to move upward. Then the loading pushing member 842 pushes all the products above the lifting and discharging member 912 in the direction of the cartridge inserting assembly 500 of the cartoning machine, so that the products enter the packaging box to realize the cartoning of the products.

[0072] The front material baffle assembly 920 is arranged on the side of the lifting and discharging assembly 910 away from the product transportation line 700. The front material baffle assembly 920 includes a front material baffle 921 and a front material baffle driving member 922. The front material baffle driving member 922 is fixedly installed on the frame 100. The front material baffle driving member 922 drives the front material baffle 921 to move up and down in the vertical direction. The front material baffle 921 is used to limit the product to prevent the product from tipping towards the carton inserting assembly 500 of the cartoning machine due to inertia.

[0073] The carton inserting assembly 500 of the cartoning machine is provided with a folding area, a transportation area, and a first direction.

[0074] The carton inserting assembly 500 of the cartoning machine includes a main cover folding assembly, a carton inserting transportation line 520, a second swing cover folding assembly 540, and a first swing cover folding assembly 530.

[0075] The carton inserting transportation line 520 is arranged within the transportation area.

[0076] Both sides of the carton inserting transportation line 520 are respectively set as the carton bottom side and the folding side.

[0077] The carton inserting transportation line 520 includes two pushing transportation lines 521. The two pushing transportation lines 521 are arranged one above the other. The packaging box is located between the upper and lower pushing transportation lines 521, and the packaging box moves forward between the upper and lower pushing transportation lines 521.

[0078] The pushing transportation line 521 includes a transportation line frame 522, a transportation line driving assembly 523, and a pushing transportation member 524. Among them, the transportation line frame 522 of the pushing transportation line 521 located below is fixedly connected to the frame 100. The transportation line frame 522 of the pushing transportation line 521 located above is slidably connected to the frame 100 up and down. The height of the pushing transportation line 521 located above is adjusted through structures such as a threaded rod and a threaded seat (in other embodiments, a linear driving device such as a linear motor can also be set to directly drive the pushing transportation line 521 located above to move up and down directly). By adjusting the height of the pushing transportation line 521 located above, the distance between the two pushing transportation lines 521 is adjusted to adapt to packaging boxes with different long sides.

[0079] The transportation line driving assembly 523 is set as a sprocket and chain driving structure (in other embodiments, the transportation line driving assembly 523 can also be set as a pulley and belt driving structure). The number of pushing transportation members 524 is set to be multiple. It should be understood that the multiple pushing transportation members 524 are evenly arranged on the chain of the transportation line driving assembly 523. The transportation line driving assembly 523 can cooperate with a power source to realize the cyclic movement of the pushing transportation line 521.

[0080] The cartoning machine is also provided with a packaging box limiting component 550.

[0081] The packaging box limiting component 550 includes a packaging box limiting member 551 and a packaging box limiting driving member 552. The packaging box limiting driving member 552 is set as a linear cylinder (in other embodiments, a linear motor can also be used).

[0082] The packaging box limiting member 551 is driven by the packaging box limiting driving member 552 to move. The packaging box limiting member 551 is inserted between the two pushing transport lines 521 along the left and right sides of the pushing transport line 521.

[0083] A plurality of packaging box limiting members 551 are provided. In this embodiment, three packaging box limiting members 551 are provided (in other embodiments, the number of packaging box limiting members 551 can also be set to four, five, etc. to adapt to the number of workstations). The arrangement direction of the three packaging box limiting members 551 is parallel to the first direction. The plurality of packaging box limiting members 551 limit the packaging box to form a plurality of workstations, facilitating the execution of different processes.

[0084] The first flap folding assembly 530 includes a second flap folding driving member 533, a first flap folding member 531, and a first flap folding driving member 532.

[0085] The second flap folding driving member 533 is fixedly installed at the output end of the first flap folding driving member 532. The first flap folding driving member 532 drives the second flap folding driving member 533 to approach or move away from the transportation area.

[0086] The first flap folding member 531 is fixedly installed on the second flap folding driving member 533. The second flap folding driving member 533 drives the second flap folding driving member 533 to move in the front-rear direction.

[0087] When the packaging box is transported forward by the box inserting and transporting line 520 from the box opening mechanism, at this time, the first flap folding driving member 532 is in a contracted state. The second flap folding driving member 533 and the first flap folding member 531 are driven by the first flap folding driving member 532 to move away from the transportation area, so that the forward movement of the packaging box will not be hindered, ensuring the normal forward transportation of the packaging box.

[0088] When the packaging box is transported by the box inserting and transporting line 520 to the flap folding workstation, the second flap folding driving member 533 and the first flap folding member 531 are driven by the first flap folding driving member 532 to approach the transportation area. Subsequently, the second flap folding driving member 533 drives the first flap folding member 531 to move backward, so that the rear flap of the packaging box is folded, completing the folding operation of one of the flaps.

[0089] The first flap folding assembly 530 is disposed behind the second flap folding assembly 540. The second flap folding assembly 540 is disposed behind the main cover folding assembly. This cartoning machine folds two flaps simultaneously through the first flap folding assembly 530 and the second flap folding assembly 540.

[0090] The second flap folding assembly 540 includes a third flap folding driving member and a second flap folding member 542. The third flap folding driving member drives the second flap folding member 542 to move in the front-rear direction.

[0091] In this embodiment, the third flap folding driving member, the second flap folding driving member 533, and the first flap folding driving member 532 are all set as linear cylinders (in other embodiments, the third flap folding driving member, the second flap folding driving member 533, and the first flap folding driving member 532 can also be set as conventional linear driving devices such as linear motors).

[0092] There are also a main cover lifting plate 560 and a main cover pressing plate 570. The main cover lifting plate 560 and the main cover pressing plate 570 are respectively disposed on the front and rear sides of the folding area. The main cover pressing plate 570 is disposed behind the main cover lifting plate 560. The main cover pressing plate 570 is disposed below the first flap folding assembly 530, and the main cover lifting plate 560 is disposed below the second flap folding assembly 540. The main cover pressing plate 570 is provided with a pressing portion, and the height of the pressing portion gradually decreases from the rear to the front. The main cover lifting plate 560 is provided with a lifting portion, and the height of the lifting portion gradually increases from the rear to the front.

[0093] When the packaging box passes through the main cover pressing plate 570, the main cover of the packaging box will move downward due to contact with the pressing portion. Before folding the flaps, the packaging box will be loaded first. Since the main cover moves downward, the main cover will not block the products being loaded into the box during the loading process, making the loading process smoother and also avoiding damage to the main cover due to the influence of other components during the loading process. After loading and flap folding are completed, the carton inserting and transporting line 520 continues to transport the packaging box forward. During the process of the packaging box continuing to move forward, the main cover will contact the lifting portion of the main cover lifting plate 560. As the transportation proceeds, the main cover is gradually lifted until the main cover is lifted to the horizontal position, making preparations in advance for the next step of the operation.

[0094] The main cover folding assembly includes: a main cover flipping assembly 610, a main cover limiting assembly 620, a tongue inserting assembly 630, and a final cover inserting assembly 640.

[0095] The main cover flipping assembly 610 includes a main cover flipping plate 611 and a main cover flipping drive structure 612. The main cover flipping drive structure 612 is fixedly installed on the frame 100. The main cover flipping drive structure 612 includes a flipping linear drive device 613 and a second swing rod 614. The flipping linear drive device 613 is hinged to the frame 100. The second swing rod 614 is hinged to the output end of the flipping linear drive device 613. The second swing rod 614 is fixedly connected to a rotating shaft, and the above-mentioned rotating shaft is fixedly connected to the main cover flipping plate 611. The flipping linear drive device 613 drives the second swing rod 614 to rotate around the central axis of the rotating shaft, thereby driving the main cover flipping plate 611 to rotate around the insertion box flipping axis. The insertion box flipping axis is parallel to the first direction. The main cover flipping plate 611 is a plate-shaped member with a relatively long length.

[0096] Through the movement of the main cover flipping plate 611, the upward flipping of the main cover of the packaging box can be realized. And since the main cover flipping plate 611 is a plate-shaped structure, compared with the prior art solution of using a rod-shaped structure to push the main cover upward from the bottom to make the main cover flip and fold, it can better adapt to the main cover of a longer and softer packaging box, and can avoid the situation that the main cover of a longer and softer packaging box cannot insert the insertion tongue well into the inner side of the packaging box.

[0097] In other embodiments, the main cover flipping drive structure 612 can be directly set as a conventional rotary drive device such as a stepping motor to drive the main cover flipping plate 611 to rotate around the insertion box flipping axis.

[0098] The main cover limiting assembly 620 includes a main cover limiting member 621 and a main cover limiting drive member 622.

[0099] The main cover limiting drive member 622 is set as a linear cylinder. The main cover limiting drive member 622 drives the main cover limiting member 621 to enter or leave the folding area along the first direction. The main cover limiting member 621 is set as a rod-shaped member. The main cover limiting member 621 is driven by the main cover limiting drive member 622 to move to one end of the packaging box corresponding to the insertion tongue. The insertion tongue end of the main cover is separated from the packaging box by the main cover limiting member 621, so that the insertion tongue of the main cover is preliminarily inserted into the packaging box, preparing for the subsequent final insertion box step.

[0100] The main cover limiting drive member 622 and the third swing cover folding drive member are the same component (in other embodiments, the main cover limiting drive member 622 and the third swing cover folding drive member can also be respectively arranged as two different components and installed at appropriate positions according to the actual structure of the cartoning machine. The main cover limiting drive member 622 and the third swing cover folding drive member respectively drive the main cover limiting member 621 and the second swing cover folding member 542). By controlling different components through the same drive structure to realize the folding of the swing cover and the limiting of the main cover, the number of drive structures can be reduced to lower the production cost; and setting the main cover limiting drive member 622 and the third swing cover folding drive member as the same component can reduce the complexity of the control program.

[0101] The tongue inserting assembly 630 includes a tongue initial inserting member 631, a second tongue driving member 633, a first tongue driving member 632, and a tongue limiting piece 634.

[0102] The first tongue driving member 632 drives the tongue limiting piece 634 and the second tongue driving member 633 to approach or move away from the folding area, and the second tongue driving member 633 drives the tongue initial inserting member 631 to approach or move away from the folding area.

[0103] First, the tongue limiting piece 634 is driven by the first tongue driving member 632. The tongue limiting piece 634 approaches the folding area, causing the tongue of the main cover to be folded. After the tongue limiting piece 634 moves to its end and enters the packaging box, the first tongue driving member 632 stops driving; when the tongue of the main cover is folded, the main cover limiting drive member 622 drives the main cover limiting member 621 to move, causing the main cover limiting member 621 to withdraw from the folding area, so that the main cover limiting member 621 no longer plays a role in separating the box body and the main cover; subsequently, the tongue initial inserting member 631 is driven by the second tongue driving member 633. The tongue initial inserting member 631 approaches the transportation area. During the movement of the tongue initial inserting member 631, it will push the end of the main cover, causing the tongue of the main cover to be initially inserted into the box body, preparing for the subsequent final box inserting step.

[0104] The final cover inserting assembly 640 includes a final cover inserting member 641 and a final cover inserting drive member 642. The final cover inserting drive member 642 drives the final cover inserting member 641 to approach or move away from the transportation area. After the packaging box is processed by the tongue inserting assembly 630, it is transported to the final box inserting assembly by the transportation line 521. The final cover inserting drive member 642 drives the final cover inserting member 641 to approach the transportation area, and the final cover inserting member 641 pushes the main cover towards the inside of the packaging box, causing the tongue initially inserted into the packaging box by the tongue inserting assembly 630 to be pushed by the final cover inserting member 641, so that the tongue is completely inserted into the packaging box to complete the entire tongue inserting action.

[0105] The above has specifically described the preferred embodiments of the present invention. However, the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
