[0002] Packaging refers to the general term for containers, materials, and auxiliary materials used according to certain technical methods to protect products, facilitate storage and transportation, and promote sales during the distribution process. Depending on the process requirements, some product packaging boxes require further packing. For example, in the tobacco product packaging field, a typical packaging method is a two-stage "small box-carton" sealing structure: after packing cigarettes into rigid paper boxes, multiple small boxes are arranged in a specific way to form a larger carton. However, this two-stage sealing method requires operators to complete multiple grasping actions within a specified time. After continuous operation for a period of time, work efficiency will significantly decrease, leading to poor production line efficiency and wasting time and effort. Utility Model Content

[0035] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0036] It should be noted that although functional modules are divided in the device schematic diagram and a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first," "second," etc., in the specification, claims, and the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0038] Reference Figure 1 , Figure 2 as well as Figure 3 This application provides an automatic packaging filling device, including a base 1, and further including a feeding structure 2, a transport structure 3, a box opening structure 4, a material conveying structure 6, a packaging structure 7, a box closing structure 8, and a discharging structure 9 disposed on the base 1. The feeding structure 2 is located at one end of the length direction of the base 1, and the discharging structure 9 is located at the other end of the length direction of the base 1. The transport structure 3 and the material conveying structure 6 are laid and extended along the length direction of the base 1, and the box opening structure 4, the packaging structure 7, and the box closing structure 8 are arranged sequentially from the feeding structure 2 to the discharging structure 9.

[0039] When the automatic packaging and filling equipment is running, the carton is transported to one end of the base 1 along the length direction via the feeding structure 2 and then enters the transport structure 3. Driven by the transport structure 3, the carton sequentially enters the opening structure 4, the packing structure 7, and the closing structure 8. The carton is opened in the opening structure 4 and then enters the packing structure 7. The packing structure 7 takes small boxes from the feeding guide 61 and puts them into the carton to stack them into two layers of small box packaging. The carton containing the two layers of small box packaging enters the closing structure 8 for sealing and finally is transported out via the unloading structure 9. The entire packaging process does not require manual operation, can run stably for a long time, and ensures packaging efficiency and packaging quality.

[0040] Specifically, the feeding structure 2 is located at one end of the base 1 along its length. The feeding structure 2 includes a feeding component 21 and a limiting component 22 disposed on the feeding component 21. The feeding component 21 is used to feed the packaging boxes into the limiting component 22, which is used to limit and transfer the packaging boxes. The feeding component 21 includes several feeding rollers and a feeding belt rotatably connected to the base 1. The feeding rollers are horizontally arranged, and the feeding belt covers them. The feeding rollers are driven to rotate by a motor. The feeding belt has baffles on both sides, allowing stacked packaging boxes to be placed on it. Driven by the feeding rollers, the stacked packaging boxes are transported along the feeding belt.

[0041] The limiting component 22 is located on the side of the feeding component 21 near the positioning conveyor structure, and has a limiting channel communicating with the positioning conveyor structure. In this embodiment, the limiting component 22 includes a limiting connecting seat 221 fixedly connected to the feeding component 21. The upper part of the limiting connecting seat 221 communicates with the feeding belt, and the lower part of the limiting connecting seat 221 communicates with the positioning conveyor structure. The limiting connecting seat 221 has limiting side plates 2211 on both sides of its width. The limiting side plates 2211 have folded edges that block and limit the packaging boxes. The two limiting side plates 2211 together form a limiting channel. When stacked packaging boxes are transported to the limiting connecting seat 221, the packaging boxes fall along the limiting channel of the limiting connecting seat 221 to the positioning conveyor structure.

[0042] When stacked packaging boxes fall directly along the limiting channel, they are prone to misalignment, affecting subsequent processes. To ensure that the packaging boxes fall normally, the feeding structure 2 also includes a buffer component 23. In this embodiment, the buffer component 23 includes a buffer block 231 disposed below the limiting connecting seat 221 and a buffer driving component 232 for driving the buffer block 231. A through hole is provided below the limiting connecting seat 221, and the buffer block 231 passes through the through hole, so that the buffer block 231 is connected to the limiting channel and slidably connected to the limiting connecting seat 221. The buffer driving component 232 is a buffer cylinder. Under the drive of the buffer cylinder, the buffer block 231 can rise or fall within the limiting channel to support the stacked packaging boxes, allowing the packaging boxes to move to the bottom of the limiting channel with support. A pushing component is provided on the side of the limiting connecting seat 221 away from the positioning conveying structure. The pushing component includes a pushing cylinder and a pushing block. Driven by the pushing cylinder, the pushing block pushes the packaging box out from the bottom of the limiting channel and into the positioning conveying structure.

[0043] Reference Figure 4 , Figure 5 as well as Figure 6 The transport structure 3 includes a transport assembly 31 for transporting carton, a plurality of positioning components 32 disposed on the transport assembly 31, and a positioning drive assembly 33 for opening the positioning components 32. Specifically, to accommodate the installation of the transport assembly 31, the base 1 has a transport groove along its length. The transport assembly 31 includes a plurality of transport rollers 311 rotatably connected to the base 1 and a conveyor belt 312. The plurality of transport rollers 311 are located in the transport groove and are arranged along the length of the transport groove. The conveyor belt 312 covers the plurality of transport rollers 311. The transport rollers 311 are driven by a motor, and under the drive of the transport rollers 311, the conveyor belt 312 drives the plurality of positioning components 32 to move.

[0044] Several positioning components 32 are evenly arranged along the length of the conveyor belt 312. Each positioning component 32 includes a positioning fixture 321 for clamping and fixing the strip box, and a positioning drive component 33 faces the positioning component 32. Taking a single positioning fixture 321 as an example, a single positioning fixture 321 includes two fixture seats 3211, and there is a cavity between the two fixture seats 3211 for accommodating the strip box. It is understood that a single positioning fixture 321 has a cavity, and a single positioning fixture 321 can also cooperate with adjacent positioning fixtures 321 to form a cavity.

[0045] On opposite sides of adjacent fixture seats 3211, there are first limiting seats 32111 and second limiting seats 32112 to prevent the strip box from accidentally entering. The first limiting seat 32111 is fixed in position, and a first limiting block 3212 is slidably connected to the outside of the first limiting seat 32111. The second limiting seat 32112 is slidably connected to the fixture seat 3211 and is located at the four corners of the fixture seat 3211. A second limiting block 3213 is slidably connected to the inside of the second limiting seat 32112. The first limiting block 3212 and the second limiting block 3213 are slidably connected to the corresponding limiting seats by springs. The springs apply a force to the first limiting block 3212 and the second limiting block 3213 toward the other side. In the initial state, the first limiting block 3212 and the second limiting block 3213 extend under the action of the spring, blocking the packaging box from entering and preventing the packaging box from being pushed in by mistake. Subsequently, under the drive of the positioning drive component 33, the first limiting block 3212 and the second limiting block 3213 open to allow the packaging box to be sent in.

[0046] After the packaging box is fed in, the positioning fixture 321 clamps the packaging box under the drive of the positioning drive component 33, that is, the first limiting block 3212 and the second limiting block 3213 open, and the packaging box is fed between the two positioning fixtures 321. Specifically, the first limiting block 3212 is clamped at the middle position in the width direction of the packaging box, and the first limiting block 3212 is used to position and fix the overall position of the packaging box. The second limiting blocks 3213 are clamped on both sides in the width direction of the packaging box, one of which is the rotating side of the outer cover, so that one of the second limiting blocks 3213 can be used to restrict the rotation of the outer cover of the packaging box, so as to prevent the outer cover from being accidentally opened and affecting subsequent processes. It should be noted that the number and position of the limiting blocks can be adjusted according to actual needs.

[0047] The positioning drive assembly 33 includes a first positioning drive member 331 and a second positioning drive member 332. The first positioning drive member 331 is a cylinder. The first positioning drive member 331 is provided with a wedge 3311 facing the first limiting block 3212. The first limiting block 3212 has a first groove. The wedge 3311 contacts or disengages from the first groove. Under the drive of the cylinder, the wedge 3311 extends out and contacts the first groove. Under the drive of the wedge 3311, the two first limiting members move away from each other to open. Similarly, the second positioning drive 332 is a cylinder. The second positioning drive 332 is provided with a top block 3321 facing the second limiting block 3213. The second limiting block 3213 has a second groove. The top block 3321 contacts or disengages from the second groove. Under the drive of the cylinder, the top block 3321 extends out and contacts the second groove. Under the drive of the top block 3321, the two second limiting blocks 3213 and the corresponding second limiting seats 32112 move away from each other to open and release the limiting of the outer cover.

[0048] Reference Figure 7 After the packaging box is fed in, the first positioning drive 331 moves away from the corresponding groove, causing the first limiting block 3212 to clamp onto both sides of the packaging box; the second positioning drive 332 remains open, allowing the box opening structure 4 to open the outer cover of the packaging box. The box opening structure 4 opens the packaging box. Specifically, the box opening structure 4 includes a box opening support 41 disposed on the base 1, a box opening assembly 42, and a box opening drive 43 for driving the box opening assembly 42. The box opening support 41 is fixedly installed on the base 1 and is located on one side of the feeding structure 2. The box-opening assembly 42 includes a box-opening rotating arm 421 rotatably connected to the box-opening support base 41 and several box-opening suction cups 422 disposed on the box-opening rotating arm 421. The several box-opening suction cups 422 face the positioning assembly 32. In order to adapt to the installation of the box-opening rotating arm 421, the box-opening support base 41 has box-opening guide rails 411 on both sides. The box-opening guide rails 411 are arc-shaped and face the feeding structure 2. The box-opening guide rails 411 have guide rail grooves along their extension direction. Correspondingly, the box-opening rotating arm 421 is located between the two box-opening guide rails 411 and passes through the box-opening support base 41. One end of the box-opening rotating arm 421 has a swing arm slidably connected to the guide rail groove. The several box-opening suction cups 422 are disposed on the swing arm. The other end of the box-opening rotating arm 421 has a transmission arm. The swing arm and the transmission arm are hinged. The other end of the transmission arm has a rotating shaft, which is connected to the box opening drive component 43. The box opening drive component 43 is a motor. The rotating shaft is connected to the box opening drive component 43 through a coupling, so that the box opening assembly 42 forms a centerless box opening structure 4.

[0049] When the box-opening drive unit 43 is activated, it drives the transmission arm to rotate via the drive shaft. The rotating transmission arm drives the swing arm to slide along the box-opening guide rail 411, so that the swing arm carries the box-opening suction cup 422 along a preset path to approach the packaging box. After the box-opening suction cup 422 contacts the packaging box, it adheres to the outer cover of the packaging box. The box-opening drive unit 43 drives the swing arm to slide in the opposite direction, and the box-opening suction cup 422 drives the outer cover to open. After the outer cover is opened, the box-opening suction cup 422 releases its adhesion. At the same time, the second positioning drive unit 332 releases the limit on the second limiting block 3213. Since the outer cover is now open, the second limiting block 3213 located on one side of the outer cover will press against one side of the outer cover. The second limiting block 3213 located on the other side of the outer cover will cooperate with the first limiting block 3212 to position the packaging box. Subsequently, the conveying component 31 and the positioning component 32 move to drive the packaging box into the next structure.

[0050] Reference Figure 8 as well as Figure 9 To ensure the positional accuracy of the carton for proper alignment with the packaging structure 7, the automatic packaging filling equipment also includes a conveying and alignment structure 5. The conveying and alignment structure 5 includes a fixed base 51 mounted on the base 1, a lifting and alignment component 52 slidably connected to the fixed base 51, and an alignment drive component 53 for driving the lifting and alignment component 52. The lifting and alignment component 52 faces the positioning component 32. Specifically, the fixed base 51 is located below the base 1 and has several fixing posts 511. The fixing posts 511 are fixedly connected to the base 1 to fix the position of the fixed base 51.

[0051] The lifting and alignment assembly 52 includes a lifting plate 521 slidably connected to the fixed base 51. To accommodate the installation of the lifting plate 521, the fixed base 51 is provided with several guide slide seats, and the lifting plate 521 is provided with several guide slide columns 5211. The guide slide columns 5211 are slidably connected to the guide slide seats, and a return spring is provided between the guide slide columns 5211 and the guide slide seats. Driven by the alignment drive assembly 53, the lifting plate 521 rises and falls relative to the fixed base 51 under the guidance of the guide slide columns 5211. When the lifting plate 521 is lifted, it aligns with the positioning assembly 32. After alignment, the lifting plate 521 quickly returns to its original position under the action of the return spring to prepare for the next lifting operation.

[0052] To align the positioning component 32, the lifting plate 521 is provided with several alignment posts 522 passing through the base 1. The alignment posts 522 are located at the four corners of the lifting plate 521. The positioning component 32 has alignment holes 321121 for engaging with the alignment posts 522. The alignment posts 522 are either inserted into or disengaged from the alignment holes 321121. In this embodiment, the alignment holes 321121 are located in the second limiting seats 32112. When the lifting plate 521 is raised, the four alignment posts 522 will respectively pass into the alignment holes 321121 of the four second limiting seats 32112. At this time, the four second limiting seats 32112 will be aligned under the action of the alignment posts 522, thereby driving the packaging box to be aligned and ensuring the alignment accuracy of the packaging box.

[0053] The alignment drive assembly 53 includes an alignment drive motor 531 mounted on the fixed base 51 and an alignment shaft mounted on the alignment drive motor 531. The alignment shaft is provided with a plurality of alignment cams 532, which abut against the lifting plate 521 and the base 1. The alignment drive motor 531 is connected to the alignment shaft via a coupling. When the alignment drive motor 531 is started, it drives the alignment shaft to rotate. The rotating alignment shaft drives the plurality of alignment cams 532 to rotate, thereby driving the lifting plate 521 to move up and down.

[0054] Reference Figure 10 as well as Figure 11 The conveying structure 6 is located on one side of the packaging structure 7. The conveying structure 6 includes a conveying guide rail 61 for transporting small boxes. The conveying guide rail 61 extends along the length of the base 1 and is parallel to the conveyor belt 312 of the transport structure 3. In this embodiment, the conveying guide rail 61 can simultaneously transport two layers of small boxes. The conveying guide rail 61 has a bottom material belt 62, and side material belts 63 are also provided on both sides of the conveying guide rail 61. The bottom material belt 62 and the side material belts 63 surround each other to form a cavity that can accommodate two layers of small boxes. During material transport, the bottom material belt 62 and the side material belts 63 run synchronously with the same rotation speed. The bottom material belt 62 is used to drive the first layer of small boxes located below, and the side material belts 63 are used to drive the second layer of small boxes located above, thereby realizing the simultaneous material transport of two layers of small boxes.

[0055] Reference Figure 10 , Figure 12 as well as Figure 13The packaging structure 7 includes a first packaging component 71 and a second packaging component 72. The first packaging component 71 is used to load a first layer of small packages, and the second packaging component 72 is used to load a second layer of small packages. The first packaging component 71 includes a first packaging guide rail 711, a first material-picking component 712 disposed on the first packaging guide rail 711, and a first packaging drive component 713. The first packaging guide rail 711 is located above the transport structure 3. One end of the first packaging guide rail 711 in the length direction is located above the conveying guide rail 61, and the other end of the first packaging guide rail 711 in the length direction is located above the positioning fixture 321. The first material-picking component 712 faces the conveying structure 6. The first material-picking component 712 includes a first material-picking seat disposed on the first packaging guide rail 711. The first material-picking seat is driven by the first packaging drive component 713, which is a cylinder. The first material-picking seat is provided with a first material-picking suction cup, which faces the conveying structure 6. Driven by the first packaging guide rail 711, the first material picking seat moves to the material conveying guide rail 61. After the first material picking suction cup picks up several small boxes, the first packaging guide rail 711 drives the first material picking suction cup to place several small boxes on the first layer of the carton.

[0056] Similarly, the second packaging assembly 72 includes a second packaging guide rail 721 and a second material-picking component 722 disposed on the second packaging guide rail 721, the second material-picking component 722 facing the conveying structure 6. One end of the second packaging guide rail 721 in the length direction is located above the conveying guide rail 61, and the other end of the second packaging guide rail 721 in the length direction is located above the positioning fixture 321. The second material-picking component 722 includes a second material-picking seat 7221 disposed on the first packaging guide rail 711. In this embodiment, in order to adapt the second material-picking component 722 to different process requirements, the second material-picking seat 7221 is hinged with a rotating seat 7222. The rotating seat 7222 is driven to rotate by a cylinder. The rotating seat 7222 is provided with a second material-picking suction cup 7223, the second material-picking suction cup 7223 facing the conveying structure 6. By setting a rotating seat 7222, the rotating seat 7222 can rotate relative to the second picking seat 7221, thereby causing the material to flip and be placed on the open outer cover of the carton. That is, the second picking unit 722 can either place the material on the first layer of material for further stacking, or place the material on the open outer cover, thereby meeting different process requirements and increasing the applicability of the packaging box packing device.

[0057] Looking back Figure 8Furthermore, in this embodiment, to prevent the outer lid of the packaging box from closing during the packaging process, the base 1 is provided with several baffles 11 along the conveyor groove. The baffles 11 are horizontally positioned and located at the first packaging assembly 71 and the second packaging assembly 72. When the positioning assembly 32 moves the packaging box with its outer lid open to this position, the baffles 11 will be positioned between the outer lid and the packaging box, thereby preventing the outer lid from closing. After packaging is completed, the box moves to the closing structure 8, and the box disengages from the baffles 11 to release the restriction on the outer lid.

[0058] Reference Figure 14 as well as Figure 15 The closing box structure 8 includes a closing box guide rail 81, a closing box pusher 82 disposed on the closing box guide rail 81, and a closing box blocking seat 83 disposed on the base 1. The closing box blocking seat 83 is located on one side of the closing box pusher 82. In this embodiment, the closing box pusher 82 includes a closing box seat 821 disposed on the closing box guide rail 81. The closing box seat 821 is provided with a closing box tilting baffle 822, which faces the closing box blocking seat 83. The closing box blocking seat 83 has a closing box crossbar 831, which is horizontally disposed. The closing box tilting baffle 822 is close to or away from the closing box crossbar 831. Driven by the closing box guide rail 81, the closing box tilting baffle 822 abuts against the box and pushes the box. One side of the closing box tilting baffle 822 contacts the outer cover of the box and the small box placed on the outer cover, while the other side of the closing box tilting baffle 822 contacts the first layer of small boxes in the box.

[0059] Driven by the box-closing tilt baffle 822, the carton moves toward the box-closing crossbar 831. When the open outer cover of the carton touches the box-closing crossbar 831, the box-closing tilt baffle 822 reaches its limit stroke and begins to return. During this process, the outer cover contacts the box-closing crossbar 831 and begins to close. During the closing process, the outer cover leans against the returning box-closing tilt baffle 822 to prevent the small boxes filled in the outer cover from falling out, until the outer cover is closed.

[0060] To ensure the outer cover is closed, the closing structure 8 also includes a pressing assembly 84. The pressing assembly 84 includes a pressing seat 841 fixed to the base 1. The pressing seat 841 is provided with a pressing rod 842 and a pressing drive component 843 for driving the pressing rod 842. The pressing drive component 843 is a cylinder. The pressing rod 842 is L-shaped to fit the shape of the carton. When the outer cover is closed, the pressing drive component 843 drives the pressing rod 842 to press down, and the pressing rod 842 presses against the outer cover of the carton to ensure the outer cover is closed.

[0061] The unloading structure 9 includes an unloading seat, on which an unloading conveyor belt is installed. When the outer cover is closed, the carton with two layers of small boxes has been packaged. The unloading conveyor belt transports the carton to a designated location for storage or to the next process.
