Description

Technical Field

[0001] This invention belongs to the field of cargo packaging technology, specifically a supply chain cargo packaging mechanism. Background Technology

[0002] In modern supply chain logistics warehousing operations, packaging and sealing of goods is a core pre-process for the storage, transportation, turnover, and distribution of goods. It directly affects the integrity of the packaging, the safety of storage and transportation, and the overall efficiency of logistics operations. Currently, the mainstream packaging method in the industry is manual or semi-automatic packaging. This involves neatly packing the goods into a standard cardboard box, then manually folding the four cardboard pieces at the top of the box together, and finally wrapping and sealing the opening of the box with tape. This method is simple in structure and widely adaptable, and is widely used in various warehousing, e-commerce, and logistics sorting scenarios.

[0003] In conventional operations, relying solely on manual temporary folding of cardboard followed by direct application of adhesive can easily lead to issues such as springback, warping, and misalignment of the folded cardboard at the top of the carton. The four cardboard pieces cannot maintain a flat and aligned folded state, resulting in gaps or unevenness at the carton opening. Applying tape in this situation can easily result in loose tape, incomplete sealing, or partial leaks. This not only leads to insufficient carton sealing strength but also increases the risk of opening cracks, cargo spillage, and dust and moisture intrusion during subsequent warehousing, stacking, and transportation, causing damage to the goods. Furthermore, it severely impacts the standardization and consistency of batch packaging operations, significantly reducing the overall efficiency of supply chain cargo packaging and failing to meet the demands of modern logistics for high-speed, large-scale, and standardized packaging operations. Therefore, this invention provides a supply chain cargo packaging mechanism. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a supply chain cargo packaging mechanism of the present invention includes a roller conveyor for conveying cargo and a sealing machine for sealing the opening of a carton. The sealing machine is fixedly installed on the top of the roller conveyor, and a limiting member for limiting the carton is provided on the top of the roller conveyor. Limiting components include: Two upright plates are symmetrically fixedly installed on the top of the roller conveyor. A guide rail is fixedly installed between the two upright plates. Sliding blocks are symmetrically slidably installed in the inner cavity of the guide rail. A bidirectional threaded rod is rotatably installed in the inner cavity of the guide rail. Each of the two sliding blocks has a threaded hole on one side that matches the bidirectional threaded rod. Each of the two sliding blocks has a baffle fixedly installed at the end extending outside the guide rail to limit the sides of the carton. A drive motor for rotating the bidirectional threaded rod is fixedly installed at one end of the guide rail. A folding piece is provided between the two baffles for folding the cardboard in half.

[0006] Both baffles are designed with an L-shaped structure, and a square frame plate is fixedly installed on the end of each baffle away from the sliding block. An extension plate is provided on the end of each baffle away from the sliding block. A square groove that matches the square frame plate is opened at the edge of the extension plate near the baffle. The end of the square frame plate away from the baffle extends into the inner cavity of the square groove.

[0007] Hydraulic cylinders are fixedly installed on the outer walls of both baffles, and the power output end of the hydraulic cylinders is fixedly connected to the top of the extension plate. Guide ears are symmetrically fixedly installed on both sides of the two extension plates. Guide rods are slidably installed on one side of the multiple guide ears, and one end of each guide rod is fixedly connected to the outer wall of the baffle.

[0008] The bottom of the two baffles and the two extension plates are all fixedly installed with limiting plates for limiting the carton. The side of the limiting plate closest to the carton is flush with the side of the extension plate and the baffle.

[0009] The folding component includes multiple main rods and levers. The tops of the two baffles and two extension plates are rotatably mounted with main rods perpendicular to themselves. The tops of the multiple main rods are fixedly mounted with levers perpendicular to themselves. Both ends of the multiple levers are fixedly mounted with pressing strips for pressing the folded cardboard.

[0010] The bottom of multiple main rods is fixedly installed with transmission gears. The inside of the two extension plates and the two baffles are slidably installed with rack plates that engage with the transmission gears. One end of each rack plate is provided with a threaded groove that communicates with the other end of itself. The inner cavity of each threaded groove is provided with a drive threaded rod. The rack plate installed inside the baffle is provided with a threaded groove that communicates with the other end of itself. The inner cavity of the threaded groove is provided with a drive threaded rod. One end of each of the two drive threaded rods 2 is fixedly equipped with a transmission rod, and one end of each of the two drive threaded rods 1 is provided with a receiving hole that matches the transmission rod. The outer wall of the transmission rod and the inner wall of the receiving hole are both set as a "+" shaped structure. The threaded grooves opened on the outer walls of the drive threaded rods 1 and 2 are rotated in opposite directions. The interiors of the two baffles and the two extension plates are provided with movable chambers for the movement of the folding parts.

[0011] Limiting slide rails are fixedly installed inside the two baffles and the two extension plates. Sliding strips are slidably installed in the inner cavities of the multiple limiting slide rails. The multiple sliding strips extend to one side of the limiting slide rails and are fixedly connected to one side of the multiple rack plates respectively.

[0012] A fixed frame is provided between the two baffles. The top of the fixed frame is fixedly connected to the bottom of the guide slide rail. A drive tube is rotatably installed inside the fixed frame. Slide rods are slidably installed at both ends of the drive tube. A bevel gear 1 is fixedly installed at the ends of the two slide rods that are far apart from each other. A bevel gear 2 that meshes with bevel gear 1 is fixedly installed at the ends of the two drive threaded rods that extend to the outside of the baffle. A sealing box is sleeved on the outside of the meshing bevel gear 1 and bevel gear 2. One side of the sealing box is fixedly connected to one side of the baffle. Guide bars are fixedly installed on the outer walls of both slide rods along their own axis, and the inner wall of the drive tube is provided with grooves that are distributed in a ring shape and are adapted to the guide bars. A drive motor is fixedly installed inside the fixed frame. A bevel gear three is fixedly installed at the power output end of the drive motor. A bevel gear four, which meshes with the bevel gear three, is fixedly sleeved on the outer wall of the drive tube.

[0013] A top plate for lifting the cardboard is slidably installed directly below roller conveyor one, and part of the rollers of roller conveyor one are configured as a two-section structure. Roller conveyor two for conveying the packaged carton is fixedly installed at one end of roller conveyor one.

[0014] The beneficial effects of this invention are as follows: 1. By using a bidirectional threaded rod to drive the two side baffles to clamp and position synchronously, and in conjunction with a retractable extension plate and a limiting plate, the carton is omnidirectionally limited and fixed. This effectively solves the problems of unrestrained positioning and easy displacement and shaking of the carton during the tape sealing process in existing technologies. Through precise limiting by the mechanical structure, the carton maintains a stable posture at the sealing station, avoiding defects such as skewed tape adhesion, air pockets, and misalignment. This significantly improves the regularity and sealing accuracy of the carton seal, reduces waste of packaging materials, and effectively prevents goods from getting damp, scattering, or being damaged due to poor sealing. This significantly improves the packaging quality and storage and transportation safety of goods in the supply chain.

[0015] 2. By setting up a linkage folding mechanism, and using a gear rack and pinion system in conjunction with a multi-stage bevel gear transmission, the four surrounding paddles and pressing strips rotate synchronously. This automatically completes the folding, flattening, and pre-pressing of the four top packaging cardboard pieces of the carton, overcoming the drawbacks of traditional manual cardboard folding, such as easy springback, warping, and poor alignment. This structure enables standardized and automated pre-pressing and bonding of cardboard, providing a flat and stable working surface for tape sealing, ensuring a tight and secure carton seal. It also adapts to the packaging needs of cartons of different sizes and specifications, significantly reducing manual labor intensity, improving the automation and efficiency of cargo packaging operations, and meeting the needs of modern logistics for large-scale, standardized, and continuous packaging production.

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-7 As shown, an embodiment of the present invention provides a supply chain goods packaging mechanism, including a roller conveyor 1 for continuous transport of goods and a sealing machine 3 for tape sealing of the opening of a carton. The sealing machine 3 is fixedly installed on the top frame of the roller conveyor 1 and completes the transport and alignment sealing of the carton by relying on the roller conveyor 1. The top of the roller conveyor 1 is provided with a limiting component for limiting and fixing the carton during the carton sealing process, which can effectively prevent the carton from shifting and shaking during the sealing process and ensure the sealing accuracy.

[0021] Furthermore, such as Figure 1 As shown, the limiting component includes two symmetrically arranged vertical plates 7, which are fixedly installed on both sides of the top of the roller conveyor 1. A guide rail 4 is horizontally fixed between the two vertical plates 7. The guide rail 4 serves as a guiding and bearing structure for the limiting adjustment, ensuring the stability of the subsequent sliding adjustment of the limiting structure. Two sets of sliding blocks 6 are symmetrically slidably installed in the inner cavity of the guide rail 4. At the same time, a bidirectional threaded rod 14 is rotatably installed in the inner cavity of the guide rail 4. The threads at both ends of the bidirectional threaded rod 14 have opposite directions. The inner sides of the two sliding blocks 6 are provided with threaded holes that are compatible with the bidirectional threaded rod 14. When the bidirectional threaded rod 14 rotates, it can drive the two sliding blocks 6 to slide synchronously towards or away from each other.

[0022] Specifically, baffles 5 are fixedly installed at one end of each of the two sliding blocks 6 extending to the outside of the guide rail 4. The two baffles 5 are symmetrically arranged to clamp and limit the carton from both sides, preventing the carton from shaking or shifting during transportation or packaging. A drive motor is fixedly installed at one end of the guide rail 4. The output shaft of the drive motor is fixedly connected to the end of the bidirectional threaded rod 14, providing power for the rotation of the bidirectional threaded rod 14. At the same time, a folding component is provided between the two baffles 5, which can realize the automatic folding and pressing of the four packaging cardboards on the top of the carton, assisting in the standardized packaging operation of the carton.

[0023] Furthermore, such as Figure 4-5 As shown, both baffles 5 are designed with an L-shaped structure. The L-shaped structure can simultaneously adapt to the limiting requirements of the side and bottom edges of the carton, improving the limiting stability. A square frame plate 11 is fixedly installed at the end of each baffle 5 away from the sliding block 6. At the same time, a telescopic extension plate 10 is provided at the end of the baffle 5. A square groove 31 that matches the square frame plate 11 is opened at the edge of the extension plate 10 near the baffle 5. The end of the square frame plate 11 away from the baffle 5 slides and extends into the inner cavity of the square groove 31, so that the extension plate 10 can be stably extended and retracted along the direction of the square frame plate 11, realizing the adaptive adjustment of the limiting length and adapting to the limiting requirements of cartons of different sizes and specifications.

[0024] Specifically, such as Figure 3-4 As shown, hydraulic cylinders are fixedly installed on the outer walls of both baffles 5. The vertical power output end of the hydraulic cylinder is fixedly connected to the top of the extension plate 10. The extension plate 10 can be precisely driven to extend and retract up and down by the extension and retraction action of the hydraulic cylinder. At the same time, guide ears are symmetrically fixedly installed on both sides of the two extension plates 10. Guide rods 33 are slidably installed inside the multiple sets of guide ears. One end of all guide rods 33 is fixedly connected to the outer wall of the baffle 5. Through the sliding cooperation between the guide ears and the guide rods 33, the extension and retraction action of the extension plate 10 can be guided and limited to avoid the extension plate 10 from deviating or jamming during the extension and retraction process, thus ensuring the adjustment accuracy and operation stability.

[0025] Among them, such as Figure 4 As shown, a limiting plate 9 is fixedly installed at the bottom of each of the two baffles 5 and the two extension plates 10. The side of the limiting plate 9 closest to the carton is flush with the inner sidewall of the corresponding baffle 5 and extension plate 10. The limiting plate 9 can abut and limit the top edge of the carton, forming an all-round limiting structure with the baffles 5 and extension plates 10, further preventing the carton from shifting or tilting during tape sealing, and ensuring the overall posture of the carton is neat.

[0026] Furthermore, such as Figure 3-4 As shown, the folding component includes multiple main rods 13 and a lever 15. The tops of the two baffles 5 and the two extension plates 10 are each rotatably mounted with a main rod 13 perpendicular to itself. The multiple main rods 13 are distributed in a rectangular pattern around the top of the carton. The top of each main rod 13 is fixedly mounted with a lever 15 perpendicular to it. Each lever 15 has a pressing strip 16 fixedly mounted at both ends. When the main rods 13 rotate, they can drive the levers 15 to rotate synchronously. The pressing strip 16 flips, folds, and presses flat the four folded cardboard pieces on the top of the carton, making the cardboard pieces on the top of the carton tightly adhered and without warping or springback, providing a neat working surface for subsequent tape sealing.

[0027] Specifically, transmission gears 12 are fixedly installed at the bottom of multiple main rods 13. The transmission gears 12 rotate synchronously with the main rods 13. The interiors of the two baffles 5 and the two extension plates 10 are provided with movable chambers. A rack plate 17 that meshes with the transmission gears 12 is slidably installed inside the movable chamber. The linear sliding of the rack plate 17 can drive the transmission gears 12 to rotate, thereby driving the main rods 13 to rotate. One end of multiple rack plates 17 is provided with a through threaded groove. The inner cavity of the threaded groove is provided with a drive threaded rod 19. The end of the rack plate 17 installed inside the baffle 5 is also provided with a threaded groove. The inner cavity of the threaded groove is provided with a drive threaded rod 21.

[0028] Furthermore, such as Figure 5As shown, transmission rods 20 are fixedly installed on the outer ends of the two drive threaded rods 21. The corresponding ends of the two drive threaded rods 19 are provided with receiving holes adapted to the transmission rods 20. The outer wall of the transmission rod 20 and the inner wall of the receiving hole of the drive threaded rod 19 are both set as a "+" shaped mating structure, so that the transmission rod 20 can slide axially relative to the drive threaded rod 19, and can transmit torque synchronously to achieve linkage transmission. The outer wall threads of the drive threaded rod 19 and the drive threaded rod 21 have opposite directions, which can ensure that the rack plates 17 on both sides move synchronously in opposite directions, realize the synchronous opening and closing folding action of the four-sided paddle plates 15, and ensure the synchronicity and regularity of the folding of the carton cardboard.

[0029] Furthermore, limiting slide rails 18 are fixedly installed inside the two baffles 5 and the two extension plates 10. Sliding strips 32 are slidably installed in the inner cavity of the multiple limiting slide rails 18. The multiple sliding strips 32 extend out of the outer end face of the limiting slide rails 18 and are fixedly connected to the side wall of the corresponding rack plate 17. Through the sliding cooperation between the limiting slide rails 18 and the sliding strips 32, the movement trajectory of the rack plate 17 is precisely limited to prevent the rack plate 17 from deviating or jamming, thus ensuring the stability of the gear and rack transmission.

[0030] Specifically, such as Figure 3-6 As shown, a fixing frame 24 is provided between the two baffles 5. The top of the fixing frame 24 is fixedly connected to the bottom of the guide slide rail 4 to achieve a stable assembly of the overall structure. A horizontally arranged drive tube 23 is rotatably installed inside the fixing frame 24. Slide rods 28 are slidably installed inside both ends of the drive tube 23. A bevel gear 30 is fixedly installed at the ends of the two slide rods 28 that are far apart from each other. A bevel gear 29 that meshes with the bevel gear 30 is fixedly installed at the ends of the two drive threaded rods 21 that extend to the outside of the baffle 5. A sealing box 22 is sleeved on the outside of the meshing bevel gear 30 and bevel gear 29. The inner side of the sealing box 22 is fixedly connected to the outer wall of the baffle 5 to protect the meshing gears from dust and prevent impurities from affecting the transmission accuracy.

[0031] Furthermore, guide bars 27 are fixedly installed on the outer walls of the two slide rods 28 along their own axial direction. The inner wall of the drive tube 23 is provided with grooves that are evenly distributed in a ring shape and are adapted to the guide bars 27. The guide bars 27 slide in cooperation with the grooves, so that the slide rods 28 can extend and retract along the axial direction of the drive tube 23. At the same time, the drive tube 23 can drive the slide rods 28 to rotate synchronously through the guide bars 27, adapting to the transmission requirements of baffles 5 with different spacing and ensuring normal power transmission.

[0032] Furthermore, such as Figure 7As shown, a drive motor is fixedly installed inside the fixed frame 24. A bevel gear 3 26 is fixedly installed at the vertical power output end of the drive motor. A bevel gear 4 25 that meshes with the bevel gear 3 26 is fixedly sleeved on the outer wall of the drive tube 23. During operation, the drive motor drives the bevel gear 3 26 to rotate. Through gear meshing, the bevel gear 4 25 and the drive tube 23 rotate as a whole. In turn, the slide rod 28, the bevel gear 1 30, and the bevel gear 2 29 drive the drive threaded rod 21 to rotate, providing stable power for the overall folding mechanism.

[0033] Among them, such as Figure 1 As shown, a top plate 2 is slidably installed directly below the roller conveyor 1 to support the bottom of the cardboard. The rollers of the roller conveyor 1 corresponding to the sealing operation area are set as a two-section hollow clearance structure to provide clearance space for the lifting and lifting action of the top plate 2. The top plate 2 can support the bottom of the cardboard and, together with the top pressing structure, make the cardboard neat in all directions, avoiding the deformation of the cardboard under pressure. A roller conveyor 2 8 is fixedly installed at the discharge end of the roller conveyor 1. The sealed cardboard can be transported from the roller conveyor 1 to the roller conveyor 2 8 to realize automated continuous discharge and complete the entire packaging and sealing operation process.

[0034] The working principle of this invention is as follows: During operation, the cartons loaded with goods are conveyed to the sealing station directly below the sealing machine 3 via roller conveyor 1. The drive motor starts, driving the bidirectional threaded rod 14 to rotate, which in turn drives the sliding blocks 6 on both sides to move the baffles 5 in opposite directions, clamping and limiting the sides of the cartons. According to the height specifications of the cartons, the extension plate 10 is adjusted by the hydraulic cylinder, which works in conjunction with the limiting plate 9 to achieve precise limiting and fixing, preventing the cartons from shaking or shifting. Then, the transmission motor starts, which drives the drive threaded rod 19 and drive threaded rod 21 to rotate through multi-stage gear transmission, driving the rack plate 17 to slide, which drives the transmission gear 12 and the main rod 13 to rotate, causing the four surrounding deflector plates 15 and pressing strips 16 to rotate synchronously, folding and pressing the four folded cardboard pieces on the top of the cartons in sequence, and finally sealing them with tape by the sealing machine 3. After sealing, all mechanisms are reset, and the cartons are conveyed outward via roller conveyor 8, completing a single packaging operation. The entire process is highly automated, with precise limiting and stable sealing quality.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
