Description

Technical Field

[0001] This invention relates to the field of packaging technology, and in particular to vertical carton openers. Background Technology

[0002] In current automated packaging production lines, the handling of packaging boxes is a complex and crucial step, involving several technical challenges that urgently need to be addressed. Firstly, accurately unfolding a folded packaging box into its open state presents a series of challenges. Due to the varying materials, sizes, and shapes of packaging boxes, ensuring that they are not damaged during the opening process while simultaneously unfolding them quickly and accurately is a major technological hurdle. Traditional manual operations are not only inefficient but also struggle to guarantee consistency and accuracy in opening boxes, failing to meet the demands of modern production lines.

[0003] Meanwhile, effectively sealing the three bottom flaps (two side flaps and the bottom flap) when the box is open presents a significant technical challenge. Closing these three flaps requires precise control and positioning to ensure the box's airtightness and appearance. However, the dynamic nature of the box during transport and the flexibility of the flap material make this step difficult to automate and optimize. Furthermore, the latch connection of the bottom flap is another technical challenge, requiring accurate bending and insertion into the box to achieve a tight seal.

[0004] Finally, ensuring smooth transitions and efficient coordination between various processes during the processing of integrally molded packaging boxes is a problem that current technology needs to solve. From material handling, box opening, and flap closing 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, achieving this goal faces many challenges. Therefore, there is an urgent need for a vertical box opening machine that can automate and efficiently complete the packaging box processing process to solve the above-mentioned technical difficulties and improve production efficiency and product quality.

[0005] Therefore, we propose a vertical box-opening machine. Summary of the Invention

[0006] In response to the shortcomings of the existing production technology, the applicant provides a vertical box opening machine. By optimizing the design of key components such as the box opening assembly, the closing assembly, and the positioning device, the machine achieves automated and efficient processing of packaging boxes.

[0007] The technical solution adopted in this invention is as follows: Vertical box opener, including: The material handling assembly includes a reciprocating suction cup assembly for transferring folded packaging boxes on a storage rack; The box opening assembly overlaps with the material handling assembly at one end. Its structure includes two sliding seats that reciprocate in the same direction and can be displaced relative to each other. One sliding seat is connected to a frame structure, with a fixed push rod and a rotatable movable push rod on the frame. The other sliding seat is equipped with a drive linkage, and under the relative displacement of the two sliding seats, the movable push rod is driven to rotate toward the side of the fixed push rod, which is used for receiving, opening and conveying the packaging box. The tray connects to the box-opening component to receive the box. as well as, The closing assembly, located on one side of the bracket and extending to the upper and lower ends of the bracket, comprises the following structure: Top rod, which is located below the bracket and parallel to the bracket, closes the lower hinge in the forward direction of the packaging box; A lever is located between the top rod and the material handling assembly, and can be rotated to close the hinge on the other side of the bottom of the packaging box; The insert plate is located below one side of the bracket and moves horizontally back and forth to close the bottom cover flap of the packaging box; The insert assembly, located at the lower end of the bracket, moves vertically back and forth to insert the bottom cover flap into the packaging box.

[0008] Its further features are: The storage rack includes a rack on which folded packaging boxes are arranged side by side. A sliding pusher is also provided on the rack to move the packaging boxes. The sliding pusher is driven by a rodless cylinder to load the boxes one by one.

[0009] The material handling assembly includes a first sliding seat, which is slidably mounted on a slide rail and displaced by a first telescopic drive. The suction cup assembly is fixed to the first sliding seat by a connecting rod, and the suction cup assembly includes at least one suction cup.

[0010] The two sliding seats are connected by a sliding shaft, and one of the sliding seats is fixedly connected to the drive component to achieve autonomous movement. The moving direction of the sliding seat is at a 90-degree angle to the moving direction of the material picking component.

[0011] The drive assembly includes a rotary drive device, a drive pulley, and a transmission belt. The sliding seat is connected to the transmission belt for transmission via a first fixed clamping plate.

[0012] The frame structure includes a support member and at least one connecting seat arranged in parallel, and the support member and the connecting seat are connected to each other by at least one support shaft. A fixed push rod is connected to the support member, and a movable push rod is connected to the connecting seat. The minimum distance between the fixed push rod and the movable push rod is the same as the width of the clamped surface of the packaging box. When there are two movable push rods, the two movable push rods rotate in opposite directions, and the movable push rod closer to the fixed push rod moves towards the fixed push rod and cooperates with the fixed push rod to unfold the folded packaging box.

[0013] The drive linkage includes at least one connecting shaft connected to another sliding seat, and the connecting shaft is connected to a movable push rod of the first linkage assembly, and the movable push rod rotates with the relative displacement of the two sliding seats.

[0014] The lever is connected to a lever cylinder via a second linkage assembly, and the lever rotates in the vertical direction by extending and retracting the lever cylinder.

[0015] The closing assembly also includes a fixing frame, which is L-shaped and includes a horizontal section and a vertical section. A horizontally movable fourth sliding seat is provided on the horizontal section of the fixing 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 insert plate is fixed on the fourth sliding seat by a bracket.

[0016] The closing component also includes a positioning device for intermittently positioning the packaging box, the positioning device comprising: The folding clamping assembly is connected to the vertical section of the fixed frame via a bracket that moves vertically in the vertical direction. The folding clamping assembly includes two connecting pieces that are close to each other, and the two connecting pieces expand outward on the side of the packaging box that is close to the box to facilitate clamping and positioning of the top fold of the packaging box. The claw is connected to the fourth sliding seat via a bracket, and positions and engages the packaging box intermittently as the fourth sliding seat moves.

[0017] The insert assembly includes a first insert and a second insert. The first insert and the second insert are respectively connected to the corresponding drive cylinders via connecting rods to achieve vertical telescopic movement. The first insert is used to bend the tab of the bottom cover flap, and the second insert is used to drive the bottom cover flap and the tab to move upward and seal the bottom of the packaging box.

[0018] The closing assembly also includes a drag bar, which is connected to the transmission belt via a connecting rod and a second fixing plate, and the other end of the drag bar extends to the lower end of the bracket to provide intermittent support for the packaging box.

[0019] The longitudinal section of the tow rod is a right-angled triangle with the hypotenuse facing the insert plate. The lower end line of the tow rod and the fold line of the insert tongue are on the same vertical plane. The first insert plate is located on one side of the tow rod and works with the tow rod to bend the insert tongue.

[0020] The closing assembly also includes a rotatable push plate, which is rotatably connected to a rotating shaft. The rotating shaft is connected to a fourth sliding seat via a third linkage assembly. As the fourth sliding seat moves, it drives the rotating plate to rotate, thereby continuously pushing the packaging box to move.

[0021] Also includes: An ejection assembly, located at the end of a bracket, includes an ejection cylinder and a discharge port is provided on the side of the bracket opposite the ejection cylinder. The workbench is used to support the aforementioned components.

[0022] The beneficial effects of this invention are as follows: This invention features a compact and rational structure, and is easy to operate. By optimizing the design of key components such as the box-opening assembly, the closing assembly, and the positioning device, it achieves automated and efficient processing of packaging boxes. This equipment not only improves production efficiency and product quality but also enhances its versatility and practicality. Furthermore, its compact and efficient structural design makes it a promising candidate for use in automated packaging production lines.

[0023] In addition, the present invention also has the following advantages: The box-opening assembly of this invention utilizes two reciprocating sliding seats that move in the same direction and are relatively displaceable, along with a fixed push rod and a rotatable movable push rod, to achieve precise clamping and unfolding of the packaging box. This design not only ensures the smoothness of the box-opening process but also effectively prevents damage to the packaging box during transport. Simultaneously, the rotating design of the movable push rod makes the box-opening action more flexible, adapting to packaging boxes of different sizes and shapes, thus improving the accuracy and stability of the opening process. Compared to traditional manual operation, the box-opening machine of this invention significantly improves box-opening efficiency, ensuring the continuity and high efficiency of the production line.

[0024] The top rod and lever design in the closing assembly of this invention are responsible for closing the lower end and the other side of the folds in the forward direction of the packaging box, respectively, ensuring a tight fit. The beveled design of the top rod makes the folds less prone to damage during closing, while the vertical rotation of the lever ensures accurate closing of the other side of the folds. In addition, the introduction of the drag bar provides continuous support for the packaging box, ensuring the stability of the folds after closing. This design not only improves the accuracy and reliability of fold closing but also effectively prevents deformation or damage to the packaging box during transportation.

[0025] The first and second inserts in the insert assembly of this invention enable precise control of the flap latch on the bottom cover of the packaging box. The first insert bends the flap latch, while the second insert pushes the bottom cover flap and the bent flap together into the packaging box, thus sealing the bottom cover. This design not only improves the sealing performance of the packaging box but also ensures the appearance quality of the product. Simultaneously, the cylinder-driven and linkage transmission design of the insert assembly ensures stable vertical movement of the inserts, preventing damage to the packaging box and improving work efficiency.

[0026] The positioning device in the hinge assembly of this invention includes a hinge clamping component and a claw, achieving accurate positioning of the packaging box. The hinge clamping component firmly clamps the top hinge of the packaging box, preventing the packaging box from moving left or right during subsequent processing. The claw utilizes the movement characteristics of the fourth sliding seat to intermittently position and engage the packaging box, ensuring its stability when the insert plate is inserted into the bottom hinge. This design not only improves the positioning accuracy of the packaging box but also effectively prevents displacement or deformation of the packaging box due to external forces during processing.

[0027] The vertical carton opening machine of this invention features a compact overall structure, with all parts working in concert to ensure a smooth and unobstructed process from material handling to finished product output. Key components such as the material handling assembly, carton opening assembly, tray, and closing assembly work closely together to automate the processing of packaging boxes. Meanwhile, the design of the ejection assembly and worktable provides strong support for the stable operation of the entire machine. This compact and efficient structural design not only saves space but also improves the overall capacity and reliability of the production line. Attached Figure Description

[0038] The specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0039] This invention provides a vertical box-opening machine for automatically completing the processes of picking up, opening, closing and conveying folded packaging boxes, thereby improving production efficiency and product quality.

[0040] like Figures 1-2 As shown, the vertical box-opening machine in this embodiment mainly includes important components such as a material handling component 200, a box-opening component 300, a bracket 400, and a closing component 500. It is also equipped with an ejector component 600 and a worktable 800 to support overall operation. The aim is to replace traditional manual operation with mechanical automation, achieving rapid and accurate box opening and sealing. The overall structure is compact, and all parts work together to ensure a smooth and unobstructed process from material handling to finished product output.

[0041] like Figure 1 and Figure 2 As shown, this embodiment also includes an ejector assembly 600 and a worktable 800. The ejector assembly 600 is located at the end of the bracket 400, and its structure includes an ejector cylinder, with a discharge port provided on the side of the bracket 400 opposite to the ejector cylinder. After the packaging box completes all processing steps, the ejector cylinder is activated under the instruction of the control system to eject the packaging box from the bracket 400 and drop it into a collection box or conveyor belt through the discharge port.

[0042] The workbench 800 is used to support the aforementioned components, providing a stable support platform for the entire vertical carton opening machine. 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 to form a complete and efficient production line.

[0043] like Figure 3 As shown, the storage rack 100 in this embodiment includes a rack 101 on which folded packaging boxes are arranged side-by-side. A sliding pusher 102 is also provided on the rack 101 to move the packaging boxes. The sliding pusher 102 is driven by a rodless cylinder to achieve sequential loading. The design of the storage rack 100 fully considers the storage and retrieval efficiency of the packaging boxes. The rack 101, as a storage carrier, can accommodate a large number of folded packaging boxes, meeting the needs of continuous production. The sliding pusher 102, driven by a rodless cylinder, achieves automatic pushing of the packaging boxes, ensuring both accurate retrieval and improved production efficiency. The sequential loading method avoids the accumulation and disorder of packaging boxes, ensuring the smooth operation of the production line.

[0044] like Figure 3 As shown, the material-picking component 200 in this embodiment includes a reciprocating suction cup component 203 for transferring folded packaging boxes from the storage rack 100. The material-picking component 200 is the starting point of the carton opener, responsible for accurately and quickly picking up folded packaging boxes from the storage rack 100. The suction cup component 203 firmly grips the packaging boxes using vacuum adsorption, ensuring they do not fall or shift during movement. The reciprocating design allows the suction cup component 203 to work continuously within a fixed stroke, improving material-picking efficiency.

[0045] Specifically, the material-grabbing assembly 200 includes a first sliding seat 202, which is slidably mounted on a slide rail and displaced by a first telescopic drive 201. A suction cup assembly 203 is fixed to the first sliding seat 202 via a connecting rod, and the suction cup assembly 203 includes at least one suction cup. The first sliding seat 202, acting as a moving carrier, reciprocates within a fixed stroke through the cooperation of the slide rail and the first telescopic drive 201. The suction cup assembly 203, fixed to the first sliding seat 202 via the connecting rod, ensures 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-grabbing requirements of packaging boxes of different sizes and shapes. This design is both flexible and practical, greatly improving the adaptability and reliability of the material-grabbing assembly 200.

[0046] The drive assembly 700 in this embodiment includes a rotary drive device, a drive pulley, and a transmission belt. The sliding seat is connected to the transmission belt via a first fixed clamping plate 313. The rotary drive device, as a power source, enables smooth movement of the sliding seat through the cooperation of the drive pulley and the transmission belt. The design of the first fixed clamping plate 313 ensures a tight connection between the sliding seat and the transmission belt, preventing slippage and detachment during transmission. This design is both simple and practical, effectively improving 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 the material taking component 200 at one end. The structure includes two sliding seats (second sliding seat 301 and third sliding seat 302) that reciprocate in the same direction and can be displaced relative to each other. One sliding seat is connected to a frame structure, and the frame has a fixed push rod 304 and a rotatable push rod 307. The other sliding seat is provided with a drive linkage 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 allows the fixed push rod 304 and the movable push rod 307 to work closely together, achieving precise clamping and unfolding of the packaging box. The rotational design of the movable push rod 307 ensures smooth box-opening action while preventing damage to the packaging box during conveying. The drive linkage converts the relative displacement of the sliding seats 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 a sliding shaft 312, enabling reciprocating movement in the same direction. One of the sliding seats is fixedly connected to the drive assembly 700, and moves autonomously by the drive assembly 700. The design of the sliding seat's movement direction forming a 90-degree angle with the material picking assembly 200's movement direction allows the box opening assembly 300 to immediately perform the box opening operation after the material picking assembly 200 completes the material picking, 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. The support member 303 and the connecting seat 306 are connected to each other by at least one support shaft 305. A fixed push rod 304 is connected to the support member 303, and a movable push rod 307 is connected to the connecting seat 306. The minimum distance between the fixed push rod 304 and the movable push rod 307 is the same as the width of the clamping surface of the packaging box. The parallel arrangement of the support member 303 and the connecting seat 306 ensures stable support for the fixed push rod 304 and the movable push rod 307, while also better clamping the packaging box to both sides.

[0051] 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, ensuring tightness and accuracy of clamping. When there are two movable push rods 307, the movable push rod 307 closer to the fixed push rod 304 moves towards 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 towards the tray 400. This design improves the opening efficiency and ensures the integrity and accuracy of the packaging box.

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

[0053] In this embodiment, there are two connecting shafts: a first connecting shaft 308 and a second connecting shaft 309, corresponding to the two movable push rods 307. The two connecting shafts are connected to the two corresponding movable push rods 307 via a first connecting rod assembly 310, ensuring that the relative displacement of the sliding seats can be converted into the rotational motion of the movable push rods 307. With the relative displacement of the two sliding seats, the driving connecting rod causes the movable push rods 307 to rotate towards the fixed push rod 304, thereby achieving the clamping and unfolding of the packaging box, and also enabling the conveying of the opened packaging box. This design is simple and practical, effectively improving the reliability and stability of the box-opening assembly 300.

[0054] In addition, the fixed push rod 304 is designed with a clearance hole for docking with 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 then transport the packaging box to the next process.

[0055] like Figures 6-8 As shown, in this embodiment, the bracket 400 docks with the box-opening assembly 300 to receive the opened packaging box. The bracket 400 includes two sets of rotating rollers 401, which are spaced apart. The packaging box is positioned between the two sets of rollers 401 and connected by friction to prevent it from falling. The design of the bracket 400 takes into account the stability of the packaging box during transport. The spaced arrangement of the two sets of rollers 401 ensures that the packaging box can pass smoothly and provides necessary support through friction to prevent the packaging box from falling or tilting during transport. This design is simple and practical, effectively improving the reliability and stability of transport.

[0056] like Figures 6-8As shown, the 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. It includes a top rod 501, a lever 502, an insert plate 510, and an insert assembly for closing the flaps and bottom cover of the packaging box.

[0057] The closing assembly 500 is responsible for completely sealing the packaging box after opening. The top rod 501 and the lever 502 are designed to close the lower and other folds of the packaging box in the forward direction, respectively, ensuring a tight fit. The insert plate 510 and the insert assembly are responsible for inserting the bottom cover fold into the packaging box, achieving a seal. The entire closing process is highly automated, greatly improving production efficiency and product quality.

[0058] In this embodiment, the top rod 501 is located below the bracket 400 and parallel to the bracket 400. It closes the lower end flap in the forward direction of the packaging box. The top rod 501 has an upward-facing inclined surface on the side facing the direction the packaging box is coming from, which makes it easy to fold the corresponding flap and does not easily damage the surface of the packaging box. In this embodiment, the lever 502 is positioned between the top rod 501 and the material-taking assembly 200, and its rotation closes the flap on the other side of the lower end of the packaging box. The lever 502 is connected to a lever cylinder 5022 via a second connecting rod assembly 5021. The extension and retraction of the lever cylinder 5022 enables the lever 502 to rotate vertically, closing the flap without affecting the movement of the packaging box. The connection between the lever 502 and the lever cylinder 5022 ensures the vertical rotation of the lever 502. The extension and retraction of the lever cylinder 5022 drives the rotation of the lever 502, thereby closing the flap on the other side of the packaging box. This design avoids interference with the packaging box when the lever 502 closes the flap and improves closing efficiency and accuracy.

[0059] The closing assembly 500 also includes a fixing frame 504, which is L-shaped and includes a horizontal section and a vertical section. A horizontally movable fourth sliding seat 509 is provided on the horizontal section of the fixing 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 insert plate 510 is fixed on the fourth sliding seat 509 by a bracket.

[0060] The mounting bracket 504, serving as a support structure, is L-shaped, providing both a horizontal section for mounting the fourth sliding seat 509 and a vertical section for mounting other closing components. The fourth sliding seat 509 moves horizontally via the second telescopic drive 5091, ensuring that the insert plate 510 accurately drives the bottom cover of the packaging box to fold and flip. The insert plate 510 is fixed to the fourth sliding seat 509 by a bracket, ensuring synchronous movement and stability between the insert 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 assembly 500 also includes a positioning device for intermittently positioning the packaging box. Since the upper and lower ends of the bracket 400 are open structures, if the packaging box is not positioned during the closing process, it will affect the subsequent positioning effect. The positioning device includes a folding clamping assembly 505 and a claw 5092. The folding clamping assembly 505 is connected to the vertical section of the fixed frame 504 via a bracket that moves vertically. It includes two adjacent connecting pieces. The connecting pieces are aligned with the moving direction of the packaging box and correspond to the moving path of the top fold of the packaging box. The two connecting pieces expand outward on the side closest to the packaging box to facilitate clamping and positioning the top fold of the packaging box. This design allows the folding clamping assembly 505 to firmly clamp the top fold of the packaging box, preventing the packaging box from moving left or right during subsequent processing, thereby ensuring the positioning accuracy of the packaging box. At the same time, the vertical movement design of the folding clamping assembly 505 also facilitates adjustment according to packaging boxes of different sizes, improving the versatility of the equipment.

[0062] In this embodiment, the claw 5092 is connected to the fourth sliding seat 509 via a bracket. It positions and engages the packaging box intermittently as the fourth sliding seat 509 moves. The claw 5092 utilizes the movement characteristics of the fourth sliding seat 509. When the fourth sliding seat 509 moves towards the bracket 400, the claw 5092 restricts the packaging box's movement in the forward direction, ensuring stability when the insert plate 510 is inserted into the bottom cover hinge. When the fourth sliding seat 509 retracts, the claw 5092 releases the restriction on the packaging box, allowing it to continue moving forward to the next processing stage. This intermittent positioning method ensures the stability of the packaging box during processing and improves the equipment's processing efficiency.

[0063] The positioning device ensures accurate positioning of the packaging box during processing, providing strong support for subsequent processes such as inserting the insert plate 510 and closing the bottom cover with hinges. The combined use of the hinge clamping assembly 505 and the jaws 5092 not only improves the positioning accuracy of the packaging box but also effectively prevents displacement or deformation caused by external forces during processing, thus ensuring product quality. Furthermore, the intermittent positioning method of the positioning device allows the equipment to process packaging boxes more efficiently, increasing the overall capacity of the production line.

[0064] Furthermore, to further improve the stability and reliability of the positioning device, a guide rail is installed on the vertical section of the fixed frame 504 to guide the vertical movement of the folding clamp assembly 505. The guide device design not only ensures the movement accuracy of the folding clamp assembly 505 but also effectively prevents it from swaying or shifting during movement, thereby improving the overall performance of the equipment.

[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 respectively connected to corresponding drive cylinders (specifically, the first insert drive cylinder 5072 and the second insert drive cylinder 5082) via connecting rods (specifically, the first connecting rod 5071 and the second connecting rod 5081). This design allows the inserts to extend and retract vertically, thereby achieving precise control of the flap of the packaging box bottom cover. The design of the insert assembly takes into account the need for precise control of force and position during the bending and insertion process of the packaging box bottom cover flap. Through cylinder drive and connecting rod transmission, stable vertical movement of the inserts can be ensured, avoiding damage to the packaging box and improving work efficiency.

[0066] In this embodiment, the primary function of the first insert 507 is to bend the latch 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 latch of the bottom cover hinge, and applies pressure to bend it to 90 degrees. This action is a crucial step in the sealing process of the bottom cover of the packaging box, preparing for the subsequent insertion of the latch. The shape and size of the first insert 507 are designed according to the specific shape of the latch of the bottom cover hinge of the packaging box to ensure the smooth 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, improving the versatility of the equipment.

[0067] In this embodiment, the second insert 508 is used to move the bottom cover hinge and the tongue upwards, sealing the bottom of the packaging box. After the first insert 507 completes the tongue bending, the second insert 508 moves upwards under the drive of the cylinder, pushing the bottom cover hinge and the bent tongue together into the packaging box, thereby achieving a seal on the bottom cover. The moving distance and speed of the second insert 508 are also precisely controlled to ensure that the bottom cover hinge and the 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 performance of the packaging box but also ensures the appearance quality of the product.

[0068] The closing assembly 500 includes not only components for clamping and pushing the packaging box, but also a drag bar 506. In this embodiment, the drag bar 506 is connected to the transmission belt via a connecting rod and a second fixed clamping plate 5061. This connection method allows the drag bar 506 to move with the movement of the transmission belt, achieving intermittent support for the packaging box. The design of the drag bar 506 takes into account the stability of the packaging box during the conveying process. Simultaneously, when the lower end of the packaging box loses the support of the top rod 501 and the lever 502, the two flaps at the bottom of the packaging box will remain open without support, affecting the subsequent flipping of the bottom cover flaps. Driven by the transmission belt, the drag bar 506 can move to the lower end of the packaging box at a specific time to provide support.

[0069] The longitudinal section of the drag bar 506 is a right triangle, with the hypotenuse facing the insert plate 510. That is, its upper end is at a right angle to the end near the first insert plate 507. The top continuously presses down on the two side panels at the bottom of the packaging box, thereby achieving continuous closure of the folds on both sides of the packaging box. At the same time, the lower end line of the drag bar 506 is on the same vertical plane as the fold line of the insert tongue, which facilitates the first insert plate 507 to drive the insert tongue to bend, ensuring the smooth bending and insertion of the insert tongue.

[0070] The first insert 507 is located on one side of the drag bar 506 and works with the drag bar 506 to bend the tab. When the insert plate 510 flips the bottom cover flap of the packaging box to a certain height, the fold line of the tab coincides with the lower end line of the drag bar 506. The first insert 507 moves downward under the drive of the cylinder, bending the tab of the bottom cover flap to 90 degrees. After bending, since the drag bar 506 is connected to the transmission belt, it moves away as the transmission belt moves. At this time, the second insert 508 moves vertically under the drive of the cylinder, inserting the bottom cover flap into the packaging box. The cooperation between the first insert 507 and the drag bar 506 enables the continuous operation of the tab bending and bottom cover insertion. This design not only improves work efficiency but also ensures the accuracy and stability of the operation. At the same time, the removal of the drag bar 506 provides sufficient space for the insertion of the second insert 508, avoiding interference between components.

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

[0072] In this embodiment, as Figure 7 As shown, the closing assembly 500 also includes a rotatable push plate 503. The push plate 503 is rotatably connected to a rotating shaft 5031, and the rotating shaft 5031 is connected to a fourth sliding seat 509 via a third linkage 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 linkage assembly 5032, the push plate 503 can smoothly push the packaging box forward, avoiding any stagnation or jamming during the conveying process.

[0073] As the fourth sliding seat 509 moves, the pusher plate 503 rotates and continuously pushes the packaging box, conveying it to the next workstation. This design not only ensures the continuity of the production line but also improves work efficiency. The rotation speed and pushing force of the pusher plate 503 are adjustable to accommodate packaging boxes of different sizes and weights. This flexibility allows the invention to be applied to the handling of various types of packaging boxes, improving the versatility and practicality of the equipment.

[0074] The specific working principle is as follows: A folded packaging box is placed on the material rack 101. Driven by the rodless cylinder, the sliding push plate 102 pushes the packaging box toward the material picking component 200, so that the material picking component 200 can pick up the packaging box through the suction cup component 203 within its moving stroke. After the material-grabbing component 200 picks up the packaging box, it moves towards the box-opening component 300. Upon reaching the end of its stroke, the two sliding seats (specifically the second sliding seat 301 and the third sliding seat 302) clamp the packaging box under relative displacement 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). 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 unfold as the rotating push rod and the fixed push rod 304 clamp it. With the synchronous movement of the two sliding seats, the opened packaging box is conveyed towards the bracket 400. At this time, the lower flap of the packaging box in the forward direction contacts the top rod 501, thereby closing it. Then, driven by the lever cylinder 5022, the lever 502 rotates on the vertical plane to close the flap on the other side of the packaging box. As the packaging box continues to move, the drag rod 506 moves to the lower end of the packaging box under the drive of the drive assembly 700 to continuously close the flaps on both sides. As the packaging box continues to move, the folding clamping component 505 in the positioning device can clamp the top cover fold of the packaging box; at the same time, the second telescopic drive 5091 drives the fourth sliding seat 509 to move, and the claw 5092 can also contact the packaging box, thereby performing dual positioning of the packaging box. At the same time, the insert plate 510 will also cause the bottom cover hinge to flip as the fourth sliding seat 509 moves; The first insert 507 moves vertically under the action of the first insert drive cylinder 5072. At the same time, combined with the shape of the drag bar 506 and the positional relationship between the drag bar 506 and the first insert 507, the first insert 507 bends the tongue of the bottom cover hinge to 90 degrees. Subsequently, the drag bar 506 disengages from the bottom cover hinge under the drive of the drive assembly 700. At the same time, the second insert 508 moves vertically under the drive of the second insert drive cylinder 5082, thereby inserting the bottom cover side panel into the packaging box and sealing the bottom cover of the packaging box. After the previous process is completed, the push plate 503 rotates along with the movement of the fourth sliding seat 509 to move the packaging box to the ejection station. Driven by the ejection cylinder in the ejection assembly 600, the material is driven away.
