Description

Technical Field

[0001] The invention relates to the technical field of packaging, in particular to a vertical carton opening machine. Background Art

[0002] In the current automated packaging production line, the handling of packaging boxes is a complex and critical link, which involves many technical difficulties that need to be solved urgently. First of all, accurately unfolding the folded packaging box into an open box state faces a series of challenges. Since the materials, sizes and shapes of packaging boxes vary, how to ensure that the packaging box is not damaged during the opening process while being able to unfold it quickly and accurately is a major problem in current technology. Traditional manual operations are not only inefficient, but also difficult to ensure the consistency and accuracy of box opening, and cannot meet the needs of modern production lines.

[0003] At the same time, when the box is in the open state, how to effectively seal the three hinges at the bottom (two side hinges and the bottom cover hinge) is also a technical difficulty. The closure of these three hinges requires precise control and positioning to ensure the sealing and appearance quality of the box. However, due to the dynamic nature of the box during transportation and the flexibility of the hinge material, this step is difficult to automate and make efficient. In addition, the tongue connection of the bottom cover hinge is also a technical difficulty. It is necessary to ensure that the tongue can be accurately bent and inserted into the box to achieve a tight closure of the bottom cover.

[0004] Finally, in the process of processing the overall one-piece packaging box, how to ensure the smooth connection and efficient coordination between each process is also a problem that needs to be solved in current technology. From picking up materials, opening boxes, closing pages to conveying, each step requires precise control and positioning to ensure the stability and reliability of the entire production line. However, due to the diversity of packaging boxes and the complexity of production lines, the realization of this goal faces many challenges. Therefore, there is an urgent need for a vertical box opener that can automatically and efficiently complete the packaging box processing process to solve the above technical difficulties and improve production efficiency and product quality.

[0005] For this reason, we propose a vertical carton opener. Summary of the invention

[0013] The driving connecting rod comprises at least one connecting shaft connected to another sliding seat, and the connecting shaft is connected to the movable push rod through the first connecting rod assembly, and the rotation of the movable push rod is realized with the relative displacement of the two sliding seats.

[0014] The shifting rod is connected to a shifting rod cylinder via a second connecting rod assembly, and the shifting rod is rotated in a vertical direction by the extension and retraction of the shifting rod cylinder.

[0015] The page closing assembly also includes a fixed frame, which is L-shaped and includes a horizontal section and a vertical section. A fourth sliding seat that moves horizontally is provided on the horizontal section of the fixed frame. The fourth sliding seat is connected to the second telescopic drive and moves in a direction perpendicular to the side wall of the bracket. The plug plate is fixed to the fourth sliding seat through a bracket.

[0016] The closing assembly also includes a positioning device for intermittently positioning the packaging box, and the positioning device includes: The folding leaf clamping assembly is connected to the vertical section of the fixing frame by moving along the vertical direction through the bracket. The folding leaf clamping assembly includes two connecting pieces close to each other, and the two connecting pieces are expanded outwards close to the side of the packaging box to facilitate the clamping and positioning of the cover top fold of the packaging box; The clamping claw is connected to the fourth sliding seat through a bracket, and intermittently positions and clamps the packaging box as the fourth sliding seat moves.

[0021] Also includes: An ejector assembly is located at the end of the bracket, and its structure includes an ejector cylinder, and a feed port is provided on the side of the bracket opposite to the ejector cylinder; A workbench is used to carry the aforementioned components.

[0022] The beneficial effects of the present invention are as follows: The invention has a compact and reasonable structure and is easy to operate.

The equipment not only improves production efficiency and product quality, but also enhances the versatility and practicality of the equipment. At the same time, its compact and efficient structural design also makes the equipment have a wide range of application prospects in automated packaging production lines.

[0023] At the same time, the present invention also has the following advantages: The box opening assembly of the present invention realizes the precise clamping and unfolding of the packaging box through two sliding seats that can reciprocate in the same direction and can be relatively displaced, in conjunction with the design of a fixed push rod and a rotatable movable push rod. This design not only ensures the smoothness of the box opening process, but also effectively avoids damage to the packaging box during transportation. At the same time, the rotation design of the movable push rod makes the box opening action more flexible, can adapt to packaging boxes of different sizes and shapes, and improves the accuracy and stability of box opening. Compared with traditional manual operation, the box opening machine of the present invention greatly improves the box opening efficiency and ensures the continuity and efficiency of the production line.

[0024] The design of the push rod and the lever in the leaf closing assembly of the present invention are responsible for closing the lower end of the package box in the forward direction and the hinge on the other side, respectively, ensuring that the hinge can fit tightly. The inclined design of the push rod makes the hinge less likely to be damaged during the closing process, while the vertical rotation of the lever achieves accurate closing of the hinge on the other side. In addition, the introduction of the drag rod provides continuous support for the package box, ensuring the stability of the hinge after closing. This design not only improves the accuracy and reliability of the hinge closing, but also effectively prevents the deformation or damage of the package box during transportation.

[0025] The design of the first insert and the second insert in the insert assembly of the present invention realizes the precise control of the insert tongue of the bottom cover hinge of the packaging box. The first insert is responsible for bending the insert tongue of the bottom cover hinge, while the second insert is responsible for pushing the bottom cover hinge and the bent insert tongue into the packaging box together, thereby achieving the sealing of the bottom cover. This design not only improves the sealing of the packaging box, but also ensures the appearance quality of the product. At the same time, the cylinder drive and connecting rod transmission design of the insert assembly ensures the stable movement of the insert in the vertical direction, avoids damage to the packaging box, and improves work efficiency.

[0026] The positioning device in the closing assembly of the present invention includes a folding clamping assembly and a clamping claw, which realizes accurate positioning of the packaging box. The folding clamping assembly can firmly clamp the cover top fold of the packaging box to prevent the packaging box from moving left and right during the subsequent processing. The clamping claw uses the moving characteristics of the fourth sliding seat to intermittently position and clamp the packaging box, ensuring the stability of the packaging box when the insert plate is inserted into the bottom cover folding. This design not only improves the positioning accuracy of the packaging box, but also effectively prevents the displacement or deformation of the packaging box due to external force during the processing.

[0027] The vertical carton opener in the present invention has a compact overall structure, and each part works in coordination to ensure smooth and unimpeded operation from material collection to finished product output. The key components such as the material collection component, the carton opening component, the bracket and the closing component work closely together to achieve the automated processing of the packaging box. At the same time, the design of the ejection component and the workbench also provides strong support for the stable operation of the entire equipment. This compact and efficient structural design not only saves space, but also improves the overall production capacity and reliability of the production line. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0039] The invention provides a vertical box opening machine, which is used for automatically completing the processes of taking materials, opening boxes, closing pages and conveying folding packaging boxes, thereby improving production efficiency and product quality.

[0040] like Figure 1-Figure 2 As shown, the vertical carton opening machine in this embodiment mainly includes important components such as a material taking component 200, a box opening component 300, a bracket 400 and a leaf closing component 500, and is also equipped with an ejection component 600 and a workbench 800 to support the overall operation, aiming to replace traditional manual operations through mechanical automation to achieve fast and accurate box opening and packaging of packaging boxes. The overall structure is compact, and each part works together to ensure smooth and unimpeded operation from material taking to finished product output.

[0041] like Figure 1 and Figure 2 As shown, in this embodiment, it also includes an ejector assembly 600 and a workbench 800. The ejector assembly 600 is located at the end of the bracket 400, and its structure includes an ejector cylinder, and a discharge port is provided on the side of the bracket 400 opposite to the ejector cylinder. When the package box has completed all processing steps, the ejector cylinder is started under the command of the control system, and the package box is ejected from the bracket 400 and falls into the collection box or the conveyor belt through the discharge port.

[0042] The workbench 800 is used to carry the aforementioned components and provides a stable support platform for the entire vertical carton opener. The design of the workbench 800 takes into account the overall structure and layout of the equipment. Through reasonable size and shape design, the components can be closely matched together to form a complete and efficient production line.

[0043] like Figure 3 As shown, the material storage rack 100 in this embodiment includes a material rack 101, and the folded packaging boxes are distributed side by side on the material rack 101, and a sliding push plate 102 for pushing the packaging boxes to move is also provided on the material rack 101, and the sliding push plate 102 is driven by a rodless cylinder to realize one-by-one loading. The design of the material storage rack 100 fully considers the storage and material retrieval efficiency of the packaging boxes. As a storage carrier, the material rack 101 can accommodate a large number of packaging boxes in a folded state to meet the needs of continuous production. The design of the sliding push plate 102, driven by the rodless cylinder, realizes the automatic pushing of the packaging boxes, which not only ensures the accuracy of material retrieval, but also improves production efficiency. The one-by-one loading method avoids the accumulation and confusion of packaging boxes and ensures the smooth operation of the production line.

[0044] like Figure 3 As shown, the material picking assembly 200 in this embodiment includes a reciprocating suction cup assembly 203, which is used to transfer the folded packaging boxes on the storage rack 100. The material picking assembly 200 is the starting link of the box opening machine, and is responsible for accurately and quickly picking up the folded packaging boxes from the storage rack 100. The suction cup assembly 203 firmly grasps the packaging box through the vacuum adsorption principle to ensure that it will not fall or shift during the movement. The reciprocating design enables the suction cup assembly 203 to work continuously within a fixed stroke, thereby improving the material picking efficiency.

[0045] Specifically, the material picking assembly 200 includes a first sliding seat 202, which is slidably arranged on a slide rail and driven to move by a first telescopic drive 201, and a suction cup assembly 203 is fixed to the first sliding seat 202 by a connecting rod, and the suction cup assembly 203 includes at least one suction cup. The first sliding seat 202 serves as a mobile carrier, and realizes reciprocating movement within a fixed stroke through the cooperation of the slide rail and the first telescopic drive 201. The suction cup assembly 203 is fixed to the first sliding seat 202 by a connecting rod, ensuring the synchronous movement of the suction cup and the sliding seat. The number and layout of the suction cups can be adjusted according to actual needs to meet the material picking needs of packaging boxes of different sizes and shapes. This design is both flexible and practical, and greatly improves the adaptability and reliability of the material picking assembly 200.

[0046] The driving assembly 700 in this embodiment includes a rotary driving device, a driving pulley and a transmission belt, and the sliding seat is connected to the transmission belt through the first fixed clamping plate 313 for transmission. The rotary driving device serves as a power source, and the smooth movement of the sliding seat is achieved through the cooperation of the driving pulley and the transmission belt. The design of the first fixed clamping plate 313 ensures the close connection between the sliding seat and the transmission belt, and prevents sliding and falling off during the transmission process. This design is simple and practical, and effectively improves the transmission efficiency and stability of the box opening assembly 300.

[0047] like Figure 4 and Figure 5 As shown, the box opening component 300 in this embodiment overlaps with one end of the material taking component 200, and the structure includes two sliding seats (a second sliding seat 301 and a third sliding seat 302) which can reciprocate in the same direction and can be relatively displaced. One of the sliding seats is connected to a frame structure, and a fixed push rod 304 and a rotatable movable push rod 307 are provided on the frame. The other sliding seat is provided with a driving connecting rod for receiving, opening and conveying the packaging box.

[0048] The box opening assembly 300 is responsible for unfolding the folded packaging box and conveying it to the next process. The relative displacement design of the two sliding seats enables the fixed push rod 304 and the movable push rod 307 to cooperate closely, realizing the precise clamping and unfolding of the packaging box. The rotation design of the movable push rod 307 not only ensures the smooth opening action, but also avoids damage to the packaging box during the conveying process. The function of the driving connecting rod is to convert the relative displacement of the sliding seat into the rotational motion of the movable push rod 307, thereby realizing the box opening action.

[0049] Specifically, the two sliding seats are connected by the sliding shaft 312 to achieve reciprocating movement in the same direction. One of the sliding seats is fixedly connected to the driving assembly 700 and realizes autonomous movement driven by the driving assembly 700. The design that the moving direction of the sliding seat is at a 90-degree angle with the moving direction of the material picking assembly 200 enables the box opening assembly 300 to immediately open the box after the material picking assembly 200 completes the material picking, thereby improving the continuity and efficiency of the production line.

[0050] The frame structure in this embodiment includes a support member 303 and at least one connecting seat 306 arranged in parallel, and the support member 303 and the connecting seat 306 are connected to each other through at least one supporting shaft 305. The support member 303 is connected to a fixed push rod 304, and the connecting seat 306 is connected to a movable push rod 307. The minimum distance between the fixed push rod 304 and the movable push rod 307 is the same as the width of the clamped surface of the packaging box. The parallel arrangement of the support member 303 and the connecting seat 306 ensures stable support of the fixed push rod 304 and the movable push rod 307, and better clamps them on both sides of the packaging box.

[0051] The design that the minimum distance between the fixed push rod 304 and the movable push rod 307 is the same as the width of the clamped surface of the packaging box ensures the tightness and accuracy of clamping. When there are two movable push rods 307, the movable push rod 307 close to the fixed push rod 304 moves toward the fixed push rod 304 and cooperates with the fixed push rod 304 to unfold the folded packaging box, while the other movable push rod 307 is responsible for pushing the opened packaging box to the bracket 400. This design not only improves the opening efficiency, but also ensures the integrity and accuracy of the packaging box.

[0052] The driving connecting rod in this embodiment includes at least one connecting shaft (a first connecting shaft 308 and a second connecting shaft 309) connected to another sliding seat, and the connecting shaft is connected to the movable push rod 307 through the first connecting rod assembly 310, and the movable push rod 307 is rotated with the relative displacement of the two sliding seats.

[0053] In this embodiment, there are two connecting shafts, namely the first connecting shaft 308 and the second connecting shaft 309, which correspond to the two movable push rods 307 in this embodiment. The two connecting shafts are connected to the two corresponding movable push rods 307 through the first connecting rod assembly 310, ensuring that the relative displacement of the sliding seat can be converted into the rotational movement of the movable push rod 307. With the relative displacement of the two sliding seats, the driving connecting rod drives the movable push rod 307 to rotate toward the fixed push rod 304, thereby achieving the clamping and unfolding of the packaging box, and also achieving the transportation of the packaging box after opening. This design is simple and practical, and effectively improves the reliability and stability of the box opening assembly 300.

[0054] In addition, the fixed push rod 304 is designed with an avoidance hole for docking the suction cup assembly 203 to avoid mutual interference. After the suction cup assembly 203 clamps the material and moves to the position of the fixed push rod 304, the fixed push rod 304 can transport the packaging box to the next process.

[0055] like Figure 6-Figure 8 As shown, the bracket 400 in this embodiment is docked with the box opening component 300 to receive the package box after opening. The bracket 400 includes two groups of rollers 401, which are arranged at intervals. The package box is between the two groups of rollers 401 and connected by friction to prevent the package box from falling. The design of the bracket 400 takes into account the stability of the package box during transportation. The interval arrangement of the two groups of rollers 401 not only ensures that the package box can pass smoothly, but also provides the necessary support force through friction to prevent the package box from falling or tilting during transportation. This design is simple and practical, and effectively improves the reliability and stability of transportation.

[0056] like Figure 6-Figure 8As shown, the page closing assembly 500 in this embodiment is located on one side of the bracket 400 and extends to the upper and lower ends of the bracket 400, including a top rod 501, a lever 502, an insert plate 510 and an insert sheet assembly, which are used to close the hinge and bottom cover of the packaging box.

[0057] The closing assembly 500 is responsible for completely closing the package box after opening. The design of the top rod 501 and the lever 502 is responsible for closing the hinges at the lower end and the other side of the package box in the forward direction, respectively, to ensure that the hinges can fit tightly. The insert plate 510 and the insert sheet assembly are responsible for inserting the bottom cover hinge into the package box to achieve the sealing of the bottom cover. The entire closing process is highly automated, which greatly improves production efficiency and product quality.

[0058] The push rod 501 in this embodiment is arranged below the bracket 400 and parallel to the bracket 400, closing the lower end hinge of the packaging box in the forward direction, and the push rod 501 is provided with an inclined surface with an opening upward on the side facing the packaging box, so as to facilitate folding the corresponding hinge without damaging the surface of the packaging box; The lever 502 in this embodiment is arranged between the push rod 501 and the material taking assembly 200, and closes the folding leaf on the other side of the lower end of the packaging box by rotation; the lever 502 is connected to the lever cylinder 5022 through the second connecting rod assembly 5021, and the lever 502 is rotated in the vertical direction by the telescopic movement of the lever cylinder 5022, so as to close the folding leaf of the packaging box without affecting the movement of the packaging box. The lever 502 is connected to the lever cylinder 5022 through the second connecting rod assembly 5021, so as to ensure the rotation of the lever 502 in the vertical direction. The telescopic movement of the lever cylinder 5022 drives the rotation of the lever 502, so as to close the folding leaf on the other side of the packaging box. This design not only avoids the interference of the lever 502 with the packaging box when closing the folding leaf, but also improves the efficiency and accuracy of closing the leaf.

[0059] The page closing assembly 500 also includes a fixed frame 504, which includes an L-shaped horizontal section and a vertical section. A fourth sliding seat 509 that moves horizontally is provided on the horizontal section of the fixed frame 504. The fourth sliding seat 509 is connected to the second telescopic drive 5091 and moves in a direction perpendicular to the side wall of the bracket 400. The plug plate 510 is fixed to the fourth sliding seat 509 through a bracket.

[0060] The fixing frame 504 is an L-shaped support structure, which provides a horizontal section for installing the fourth sliding seat 509 and a vertical section for installing other closing components. The fourth sliding seat 509 is horizontally moved by the second telescopic drive 5091, ensuring that the plug plate 510 can accurately drive the bottom cover of the packaging box to fold and flip. The plug plate 510 is fixed to the fourth sliding seat 509 by a bracket, ensuring the synchronous movement and stability of the plug plate 510 and the fourth sliding seat 509. This design improves the reliability and stability of the closing assembly 500.

[0061] In another embodiment, the closing leaf assembly 500 also includes a positioning device for intermittently positioning the packaging box. Since the upper and lower ends of the bracket 400 are both open structures, if the packaging box is not positioned during the closing process, the subsequent positioning effect will be affected. The positioning device includes a folding leaf clamping assembly 505 and a clamping claw 5092. The folding leaf clamping assembly 505 is connected to the vertical section of the fixed frame 504 by moving in the vertical direction through the bracket, and includes two connecting pieces close to each other. The connecting pieces are consistent with the moving direction of the packaging box and correspond to the moving path of the top cover fold of the packaging box. The two connecting pieces are close to the side of the packaging box and expand outward to facilitate the clamping and positioning of the top cover fold of the packaging box. This design enables the folding leaf clamping assembly 505 to firmly clamp the top cover fold of the packaging box, avoiding the packaging box from moving left and right during the subsequent processing, thereby ensuring the positioning accuracy of the packaging box. At the same time, the vertical movement design of the folding leaf clamping assembly 505 is also convenient for adjustment according to packaging boxes of different sizes, improving the versatility of the equipment.

[0062] The clamping claw 5092 in this embodiment is connected to the fourth sliding seat 509 through a bracket, and intermittently positions and clamps the packaging box as the fourth sliding seat 509 moves. The clamping claw 5092 utilizes the mobile characteristics of the fourth sliding seat 509. When the fourth sliding seat 509 moves toward the bracket 400, the clamping claw 5092 can limit the movement of the packaging box in the forward direction, ensuring that the packaging box remains stable when the insert plate 510 is inserted into the bottom cover fold. When the fourth sliding seat 509 is retracted, the clamping claw 5092 releases the restriction on the packaging box, allowing the packaging box to continue to move forward and enter the next processing link. This intermittent positioning method not only ensures the stability of the packaging box during the processing, but also improves the processing efficiency of the equipment.

[0063] The positioning device ensures the accurate positioning of the packaging box during the processing, and provides strong support for the subsequent insertion of the plug plate 510, the folding and closing of the bottom cover, and other processes. The coordinated use of the folding clamping assembly 505 and the claws 5092 not only improves the positioning accuracy of the packaging box, but also effectively prevents the displacement or deformation of the packaging box due to external forces during the processing, thereby ensuring the processing quality of the product. In addition, the intermittent positioning method of the positioning device also enables the equipment to process the packaging box more efficiently, improving the overall production capacity of the production line.

[0064] In addition, in order to further improve the stability and reliability of the positioning device, a guide rail is also provided on the vertical section of the fixed frame 504 to guide the vertical movement of the folding clamping assembly 505. The design of the guide device not only ensures the movement accuracy of the folding clamping assembly 505, but also effectively prevents the shaking or deviation of the folding clamping assembly 505 during the movement, thereby improving the overall performance of the device.

[0065] The insert assembly in this embodiment includes a first insert 507 and a second insert 508. The first insert 507 and the second insert 508 are connected to the corresponding driving cylinders (specifically, the first insert driving cylinder 5072 and the second insert driving cylinder 5082) through connecting rods (specifically, the first connecting rod 5071 and the second connecting rod 5081), respectively. This design enables the insert to be telescopically moved in the vertical direction, thereby achieving precise control of the folding tongue of the bottom cover of the packaging box. The design of the insert assembly takes into account the need for precise control of the force and position during the bending and insertion process of the tongue of the bottom cover of the packaging box. Through cylinder drive and connecting rod transmission, the stable movement of the insert in the vertical direction can be ensured, avoiding damage to the packaging box and improving work efficiency.

[0066] The main function of the first insert 507 in this embodiment is to bend the insert tongue of the bottom cover hinge. When the packaging box is conveyed to the designated position, the first insert 507 moves downward under the drive of the cylinder, contacts the insert tongue of the bottom cover hinge, and applies a certain pressure to bend it to 90 degrees. This action is a key step in the sealing process of the bottom cover of the packaging box, and provides preparation for the subsequent insertion of the insert tongue. The shape and size of the first insert 507 are designed according to the specific shape of the insert tongue of the bottom cover hinge of the packaging box to ensure the smooth progress of the bending process. At the same time, the driving force and moving speed of the cylinder are also adjustable to adapt to packaging boxes of different materials and thicknesses, thereby improving the versatility of the equipment.

[0067] The second plug-in piece 508 in this embodiment is used to drive the bottom cover hinge and the plug-in tongue to move upward and seal the bottom of the packaging box. After the first plug-in piece 507 completes the bending of the plug-in tongue, the second plug-in piece 508 moves upward under the drive of the cylinder to push the bottom cover hinge and the bent plug-in tongue into the packaging box, thereby achieving the sealing of the bottom cover. The moving distance and speed of the second plug-in piece 508 are also precisely controlled to ensure that the bottom cover hinge and the plug-in tongue can be accurately inserted into the packaging box, while avoiding excessive pressure or damage to the packaging box. This design not only improves the sealing of the packaging box, but also ensures the appearance quality of the product.

[0068] The leaf closing assembly 500 includes not only components for clamping and pushing the packaging box, but also a drag rod 506. The drag rod 506 in this embodiment is connected to the transmission belt through a connecting rod and a second fixed clamping plate 5061. This connection mode enables the drag rod 506 to move with the movement of the transmission belt, thereby realizing intermittent support for the packaging box. The design of the drag rod 506 takes into account the stability of the packaging box during the transmission process. At the same time, when the lower end of the packaging box loses the supporting effect of the top rod 501 and the lever 502, the two folding pages under the packaging box will still open if there is no support, which affects the subsequent flipping of the bottom cover folding pages. Driven by the transmission belt, the drag rod 506 can move to the lower end of the packaging box at a specific time to provide support for it.

[0069] The longitudinal section of the pull rod 506 is a right triangle, and the hypotenuse faces the plug plate 510, that is, its upper end is at a right angle to the end close to the first plug piece 507, and the top continuously presses the two side pages at the lower end of the packaging box, thereby realizing the continuous closure of the hinges on both sides of the packaging box. At the same time, the lower end line of the pull rod 506 and the fold line of the plug tongue are on the same vertical plane, which makes it convenient for the first plug piece 507 to drive the plug tongue to bend, thereby ensuring the smooth bending and insertion of the plug tongue.

[0070] The first plug-in piece 507 is located on one side of the drag rod 506, and cooperates with the drag rod 506 to realize the bending of the plug-in tongue. When the plug-in plate 510 turns the bottom cover hinge of the packaging box to a certain height, the fold line of the plug-in tongue just overlaps with the lower end line of the drag rod 506, and the first plug-in piece 507 moves downward under the drive of the cylinder to bend the plug-in tongue of the bottom cover hinge to 90 degrees. After the bending is completed, since the drag rod 506 is connected to the transmission belt, the drag rod 506 moves away with the movement of the transmission belt, and the second plug-in piece 508 moves vertically under the drive of the cylinder, just inserting the bottom cover hinge into the packaging box. The first plug-in piece 507 and the drag rod 506 are used in conjunction to realize the continuous execution of the two actions of the plug-in tongue bending and the bottom cover insertion. This design not only improves the work efficiency, but also ensures the accuracy and stability of the action. At the same time, the removal of the drag rod 506 also provides enough space for the insertion of the second plug-in piece 508, avoiding interference between components.

[0071] In this embodiment, in order to save space, the first plug 507 and the second plug 508 are connected to the first tongue driving cylinder 5072 and the second tongue driving cylinder 5082 through the corresponding first connecting rod 5071 and the second connecting rod 5081, so that multiple cylinders are gathered together to facilitate subsequent driving.

[0072] In this embodiment, Figure 7 As shown, the leaf closing assembly 500 also includes a rotatable push plate 503. The push plate 503 is rotatably connected to the rotating shaft 5031, and the rotating shaft 5031 is connected to the fourth sliding seat 509 through the third connecting rod assembly 5032. This design allows the push plate 503 to rotate under the drive of the fourth sliding seat 509, thereby continuously pushing the packaging box to move. Through the movement of the fourth sliding seat 509 and the transmission of the third connecting rod assembly 5032, the push plate 503 can smoothly push the packaging box forward, avoiding stagnation or jamming of the packaging box during the transmission process.

[0073] As the fourth sliding seat 509 moves, the push plate 503 rotates and continuously pushes the packaging box to transport it to the next station. This design not only ensures the continuity of the production line, but also improves work efficiency. The rotation speed and pushing force of the push plate 503 are adjustable to adapt to packaging boxes of different sizes and weights. This flexibility enables the present invention to be applicable to various types of packaging box processing, thereby improving the versatility and practicality of the device.

[0074] The specific working principle is as follows: A folded packaging box is placed on the rack 101. Driven by the rodless cylinder, the sliding push plate 102 pushes the packaging box toward the material taking component 200, so that the material taking component 200 can grab the packaging box through the suction cup component 203 within its moving range. After the material taking component 200 grabs the packaging box, it moves toward the direction of the box opening component 300. After reaching the end of the stroke, the two sliding seats (specifically the second sliding seat 301 and the third sliding seat 302) clamp the packaging box through the fixed push rod 304 and the rotating push rod (composed of the connecting seat 306, the movable push rod 307, the first connecting shaft 308, the second connecting shaft 309 and the first connecting rod assembly 310) under relative displacement. In addition, since the minimum distance between the fixed push rod 304 and the rotating push rod is the width of the clamped surface of the packaging box, the packaging box will also be unfolded with the clamping effect of the rotating push rod and the fixed push rod 304, and the opened packaging box will be transported to the direction of the bracket 400 as the two sliding seats move synchronously. At this time, the lower hinge of the packaging box in the forward direction contacts the top rod 501, thereby achieving closure. Then, driven by the lever cylinder 5022, the lever 502 rotates on the vertical plane to drive the hinge on the other side of the packaging box to close. As the packaging box continues to move, the pull rod 506 is driven by the driving assembly 700 to move to the lower end of the packaging box to continuously close the hinges on both sides. As the packaging box continues to move, the folding leaf clamping assembly 505 in the positioning device can clamp the top cover folding leaf of the packaging box; at the same time, the fourth sliding seat 509 is driven to move by the second telescopic drive 5091, and the claw 5092 can also contact the packaging box, thereby performing double positioning on the packaging box; At the same time, the inserting plate 510 also drives the bottom cover hinge to flip along with the movement of the fourth sliding seat 509; The first inserting piece 507 moves in the vertical direction under the action of the first inserting piece driving cylinder 5072. At the same time, considering the shape of the drag rod 506 and the positional relationship between the drag rod 506 and the first inserting piece 507, the first inserting piece 507 bends the inserting tongue of the bottom cover hinge to 90 degrees. Subsequently, the pull rod 506 is driven by the driving assembly 700 to separate from the bottom cover hinge. At the same time, the second insert 508 is driven by the second insert driving cylinder 5082 to move in the vertical direction, and then the bottom cover side leaf is inserted into the packaging box, thereby sealing the bottom cover of the packaging box. After the above process is completed, the push plate 503 rotates with the movement of the fourth sliding seat 509 to move the packaging box to the ejection station, and driven by the ejection cylinder in the ejection assembly 600, the material is driven to leave.

[0075] The above description is an explanation of the present invention, not a limitation of the present invention. The scope of the present invention is defined in the claims. Any form of modification may be made within the scope of protection of the present invention.
