Description

Technical Field

[0001] This utility model relates to the field of packaging equipment manufacturing technology, and in particular to an automatic boxing machine for square cans. Background Technology

[0002] Canned food is a type of packaged food made in a sealable container using sheet metal, glass, plastic, or a combination of these materials. After specific processing to achieve commercial sterility, it can be kept at room temperature for an extended period without spoiling. Cans made from sheet metal are mostly square or cylindrical in shape.

[0003] These canned goods require multiple cans to be packed into boxes, sealed, stored, and transported during the sales process. Traditionally, boxing and packing are done manually, which is labor-intensive, inefficient, and costly. To solve the boxing problem, people began to design machinery for boxing.

[0004] For example, a Chinese invention patent application with patent number 201811357221.9, entitled "An Automatic Canning Machine for Fruits and Vegetables," was published on April 5, 2019. This invention includes a can conveying device, a boxing device, and a box conveying device. A support is welded to the upper side of the base, and the can conveying device is mounted on the upper side of the support. A motor is installed on the side of the can conveying device, and a conveyor belt is installed inside the can conveying device. A baffle is installed inside the can conveying device, and a counter is installed on the upper side of the can conveying device. Cans are placed on the upper side of the conveyor belt, and an adsorption rod is installed at one end of each can. One end of the adsorption rod is connected to a telescopic rod, which is connected to a movable base. The boxing device is embedded in the left side of the movable base, and the box conveying device is located on the left side of the can conveying device. This invention provides an automatic canning machine for fruits and vegetables, which improves work efficiency by replacing manual boxing with an automatic boxing device. However, this type of box packing machine uses a row-by-row packing method. Each row of boxes requires multiple moving parts, such as suction rods, telescopic rods, and moving seats, to work together. On the one hand, the packing efficiency is relatively low, and it is difficult to form multi-layer packing. On the other hand, if there is a misalignment between adjacent rows of cans, or if the packaging box is not positioned accurately, packing failure is likely to occur, resulting in low reliability. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an automatic boxing machine for square cans, which has high boxing efficiency and high operational reliability.

[0006] To achieve the above objectives, the technical solution of this utility model is: an automatic boxing machine for square cans, including a frame, a can conveying mechanism, and a box conveying mechanism. A sorting platform is provided in the middle of the frame. The cans move horizontally into the sorting platform under the drive of the can conveying mechanism. A can blocking component is provided on the top of the sorting platform. The can blocking component is fixedly connected to the frame. The blocking surface of the can blocking component is perpendicular to the input direction of the cans. The input direction of the cans is the conveying direction in which the can conveying mechanism drives the cans to move. The cans at the front end are blocked by the can blocking component, so that multiple cans are placed close together in the middle of the sorting platform.

[0007] The material handling platform is equipped with rotatable support plates on both sides. The support plates can rotate back and forth under the drive of the first drive mechanism. After the support plates rotate downwards to the position, they form the discharge port.

[0008] A first pushing component is provided on the material handling platform. Driven by the second driving mechanism, the first pushing component moves back and forth along the horizontal and perpendicular input direction of the cans. The first pushing component pushes multiple cans onto the material receiving plates on both sides of the material handling platform.

[0009] The material support plate is equipped with a first suction cup bracket, which has multiple first suction cups with downward-facing suction nozzles. The first suction cup bracket can move up and down under the drive of the third drive mechanism.

[0010] The packaging box is conveyed to the bottom of the support plate by the packaging box conveying mechanism, and the opening at the top of the packaging box corresponds to the discharge port; multiple first suction cups pick up multiple cans on the support plate and move them downward through the discharge port to load multiple cans into the packaging box.

[0011] Preferably, the material handling platform has two material support plates on each side. These two plates can rotate back and forth in opposite directions under the drive of the first driving mechanism. Each pair of material support plates rotates downwards to their designated positions, forming a discharge port. This allows for smaller material support plates, reducing space requirements and resulting in a more compact structure.

[0012] Furthermore, the first driving mechanism preferably includes two first rotating shafts fixedly connected to one side of the material receiving plate, the two first rotating shafts being pivotally connected to the frame, and the axial directions of the two first rotating shafts being parallel to the input direction of the can. Each of the two first rotating shafts is fixedly connected to a first cylindrical gear. A first cylinder is mounted on the frame, and the first cylinder simultaneously drives two first racks to move up and down, with each of the two first racks meshing with one of the two first cylindrical gears. After the two material receiving plates rotate downwards to their designated positions, they can prevent the two upper cover plates of the packaging box from converging towards the center. This allows the two material receiving plates to rotate synchronously and avoids the can being loaded into the packaging box due to the packaging box cover plates bending towards the center, further improving the reliability of the packing operation.

[0013] Further improvements include lever mechanisms mounted on both sides of the frame beneath the material handling platform. Each lever mechanism comprises two parallel second rotating shafts pivotally connected to the frame. The axis of each second rotating shaft is perpendicular to the input direction of the cans. Each second rotating shaft is fixedly connected to a lever and a second cylindrical gear. A second cylinder is mounted on the frame, which simultaneously drives two second racks to move up and down. The two second racks mesh with the two second cylindrical gears, thereby driving the two second rotating shafts to rotate in opposite directions. When the two levers rotate downwards, they can respectively actuate one of the cover plates on the packaging box and prevent the two cover plates from bending towards the middle. This prevents the packaging box cover plates from bending towards the middle and affecting the loading of the cans into the packaging box, thus improving the reliability of the packing operation.

[0014] Further improvements include a guard plate on the feeding platform, which is fixedly connected to the frame and parallel to the feeding platform. The distance between the guard plate and the feeding platform is greater than the height of the can. The guard plate prevents the can from detaching from the feeding platform. The first pushing member has a clearance hole through which the guard plate passes. Preventing the can from detaching from the feeding platform with the guard plate further improves packing reliability and ensures continuous operation of the equipment.

[0015] In a further improvement, two positioning cylinders are installed at intervals under the material handling platform. Each positioning cylinder drives a positioning component to move up and down. The positioning component has a positioning part parallel to the input direction of the cans. The material handling platform has two elongated through holes corresponding to the two positioning components. When the positioning component moves upward, the positioning part passes through one of the elongated through holes and protrudes upward from the top of the material handling platform to perform initial positioning on one side of multiple cans. When the positioning component moves downward, the upper end of the positioning part is level with or lower than the upper surface of the material handling platform.

[0016] This initial positioning of multiple cans by the positioning part of the positioning component facilitates the subsequent movement of multiple rows of cans into the receiving plate by the first pusher, avoiding the need for the first and second rows of cans to be pushed a long distance, reducing the total movement distance of the first pusher, further saving the time required for the process, and effectively improving the packing efficiency.

[0017] Further improvements include can positioning mechanisms on both sides of the material handling platform. Multiple cans are positioned by these mechanisms before being picked up by multiple suction cups. A packaging box positioning mechanism is also provided below the material receiving plate. The packaging box is positioned so that its upper opening aligns with the feeding port. This ensures that multiple cans can be smoothly loaded into the packaging box, improving the reliability of the packing process.

[0018] Preferably, each of the can positioning mechanisms includes a first limiting rod and a second limiting rod disposed on the feeding platform. The first limiting rod is parallel to the input direction of the can, and the second limiting rod is perpendicular to the input direction of the can. The first limiting rod, the second limiting rod, the can blocking component, and the feeding plate together position multiple cans.

[0019] The packaging box positioning mechanism includes a third limiting rod, a fourth limiting rod, a push plate, and multiple second suction cups. The third limiting rod is perpendicular to the input direction of the can, and the fourth limiting rod is parallel to the input direction of the can. The push plate, driven by the third cylinder, drives one side of the packaging box to move towards the third limiting rod. The multiple second suction cups are mounted on a second suction cup bracket. The second suction cup bracket, driven by the fourth cylinder, moves back and forth in a direction perpendicular to the input direction of the can. The multiple second suction cups hold the other side of the packaging box, causing the other side of the packaging box to move towards the fourth limiting rod.

[0020] A further improvement involves a calibration plate located beneath the first suction cup support. This calibration plate is fixedly connected to the first suction cup support and has multiple clearance holes. Each clearance hole allows a portion of the first suction cup to pass through, with the suction nozzle positioned below the calibration plate. When multiple first suction cups simultaneously pick up multiple cans, the lower surface of the calibration plate contacts the upper ends of all the cans. This not only ensures that the cans are packed evenly but also better protects both the cans and the first suction cups.

[0021] In a further improvement, the can conveying mechanism includes a first belt conveyor with two parallel guide rods on it. The two guide rods guide the movement of the cans, and a guard rod is provided between the two guide rods to prevent the cans from jumping off the first belt conveyor.

[0022] The packaging box conveying mechanism includes a second belt conveyor, a third belt conveyor, and a fourth belt conveyor. The second belt conveyor is located below the first belt conveyor. The second, third, and fourth belt conveyors are arranged in parallel to each other. The third and fourth belt conveyors are located below the material support plates on both sides of the material handling platform.

[0023] A second pushing member is provided on the second belt conveyor. Driven by the fourth driving mechanism, the second pushing member moves back and forth horizontally and perpendicular to the input direction of the cans. When the second pushing member moves to one side, it pushes a package onto the third belt conveyor. When the second pushing member moves to the other side, it pushes a package onto the fourth belt conveyor. A transition plate is provided between the second belt conveyor and the third belt conveyor to allow the package to move. A limit rod is provided on the second pushing member perpendicular to the input direction of the cans. The limit rod restricts the movement of the package along the conveying direction.

[0024] The output ends of the third and fourth belt conveyors are connected to a roller conveyor, and the output end of the roller conveyor is connected to a fifth belt conveyor. A third pushing member is mounted on one side of the roller conveyor. Driven by a fifth drive mechanism, the third pushing member moves back and forth horizontally and perpendicular to the input direction of the cans, pushing the packaging boxes delivered from the third belt conveyor to the middle of the roller conveyor. A fourth pushing member is mounted on the other side of the roller conveyor. Driven by a sixth drive mechanism, the fourth pushing member moves back and forth horizontally and perpendicular to the input direction of the cans, pushing the packaging boxes delivered from the fourth belt conveyor to the middle of the roller conveyor, which then pushes the packaging boxes to the fifth belt conveyor. This mechanism not only ensures that the cans entering the sorting platform are arranged closely together and regularly, but also improves the conveying efficiency of the packaging boxes.

[0025] Preferably, the second drive mechanism includes a servo motor and a transmission mechanism. The servo motor drives the first pusher to move back and forth along a horizontal direction that is perpendicular to the input direction of the can through the transmission mechanism.

[0026] The third driving mechanism includes a servo motor and a transmission mechanism. The servo motor drives the first suction cup bracket to move up and down through the transmission mechanism.

[0027] This invention features a material handling platform in the middle of the frame. Cans, driven by a can conveying mechanism, move horizontally into the platform. The cans at the front are blocked by a can blocking component, causing multiple cans to be placed close together in the middle of the platform. Rotatable support plates are located on both sides of the platform, rotating back and forth under the drive of a first driving mechanism. After rotating downwards, the support plates form a discharge port. A first pushing component is located on the platform, moving horizontally and perpendicular to the can input direction under the drive of a second driving mechanism. The first pushing component pushes multiple cans onto the support plates on both sides of the platform.

[0028] In this design, the first pushing component moves back and forth, pushing multiple cans onto the receiving plate on one side of the material handling platform according to the process design requirements. Simultaneously, the receiving plate is equipped with a first suction cup bracket, which holds multiple downward-facing suction cups. This bracket can move up and down under the drive of the third driving mechanism. While the first pushing component pushes multiple cans onto the receiving plate on one side of the material handling platform, the multiple suction cups on the other side can hold multiple cans on the receiving plate and move them downwards through the discharge port, loading them into the packaging box. Material preparation and boxing can be performed simultaneously, effectively saving time and facilitating multi-layer boxing of cans, resulting in high boxing efficiency. Furthermore, this boxing structure offers high reliability throughout the entire boxing process, and the overall structure is relatively compact.

[0029] This invention can be used not only for the automatic packing of square canned goods, but also for the automatic packing of materials similar to square canned goods. Attached Figure Description

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0038] Figures 1 to 7 As shown, an automatic boxing machine for square cans includes a frame 1, a can conveying mechanism 2, and a box conveying mechanism 3. The cans 10 are generally rectangular. A sorting platform 4 is provided in the middle of the frame 1. The cans 10 move horizontally into the sorting platform 4 under the drive of the can conveying mechanism 2. A can blocking member 21 is provided on the top of the sorting platform 4. The can blocking member 21 is fixed to the frame 1. The blocking surface of the can blocking member 21 is perpendicular to the input direction of the cans 10. The input direction of the cans 10 is the conveying direction in which the can conveying mechanism 2 drives the cans 10 to move. Figure 1 , Figure 2 Arrow e indicates the direction; the cans 10 at the foremost position are blocked by the can blocking member 21, so that multiple cans 10 are placed close together in the middle of the material handling platform 4.

[0039] The material handling platform 4 has two rotatable material support plates 41 on both sides. The two material support plates 41 can rotate back and forth in opposite directions under the drive of the first drive mechanism 5. After each pair of material support plates 41 rotates downward into position, a discharge port 42 is formed. The first drive mechanism 5 includes two first rotating shafts 51 that are fixed to one side of the lower part of the material support plates 41. The two first rotating shafts 51 are pivotally connected to the frame 1. The axial direction of the two first rotating shafts 51 is parallel to the input direction of the can 10. Each of the two first rotating shafts 51 is fixed to a first cylindrical gear 52. The frame 1 is equipped with a first cylinder 53. The first cylinder 53 drives two first racks 54 to move up and down at the same time. The two first racks 54 mesh with the two first cylindrical gears 52 respectively. After the two material support plates 41 rotate downward into position, the two cover plates 201 on the upper part of the packaging box 20 are restricted to bend and move closer to the middle. The packaging box 20 is a common rectangular shape, and the upper part of the packaging box 20 has 4 bendable cover plates 201.

[0040] A first pushing member 43 is provided on the material handling platform 4. The first pushing member 43 moves back and forth along the horizontal and perpendicular input direction of the cans 10 under the drive of the second driving mechanism 44. When the first pushing member 43 moves to one side, it can push multiple cans 10 onto the material support plate 41 on one side of the material handling platform 4. When the first pushing member 43 moves to the other side, it can push multiple cans 10 onto the material support plate 41 on the other side of the material handling platform 4. The second driving mechanism 44 includes a servo motor and a transmission mechanism. The servo motor drives the first pushing member 43 to move back and forth along the horizontal and perpendicular input direction of the cans 10 through the transmission mechanism.

[0041] Each pair of material support plates 41 is provided with a first suction cup bracket 6, which is equipped with ten first suction cups 61 with their nozzles facing downwards. The first suction cup bracket 6 can move up and down under the drive of the third drive mechanism 62. The packaging box 20 is delivered to the bottom of the material support plate 41 under the drive of the packaging box conveying mechanism 3. The upper opening of the packaging box 20 corresponds to the discharge port 42. The ten first suction cups 61 suck up the ten cans 10 on the material support plate 41 and move downwards through the discharge port 42 to put the ten cans 10 into the packaging box 20. The third drive mechanism 62 includes a servo motor and a transmission mechanism. The servo motor drives the first suction cup bracket 6 to move up and down through the transmission mechanism.

[0042] By moving the first suction cup bracket 6 up and down multiple times, multiple layers of canned food 10 can be loaded into the packaging box 20.

[0043] A calibration plate 63 is provided below the first suction cup bracket 6, and the calibration plate 63 is fixedly connected to the first suction cup bracket 6. The calibration plate 63 has ten clearance holes 64, each clearance hole 64 allowing a portion of a first suction cup 61 to pass through. The suction nozzle of the first suction cup 61 is located below the calibration plate 63. When multiple first suction cups 61 simultaneously pick up ten cans 10, the lower end face of the calibration plate 63 simultaneously contacts the upper ends of the ten cans 10. This not only ensures that the multiple cans 10 are flat when packed, but also better protects the cans 10 and the first suction cups 61.

[0044] Both sides of the frame 1 below the material handling platform 4 are equipped with lever mechanisms 40. Each lever mechanism 40 includes two parallel second rotating shafts 45 pivotally connected to the frame 1. The axial direction of each second rotating shaft 45 is perpendicular to the input direction of the can 10. Each second rotating shaft 45 is fixedly connected to a lever 46. The ends of the two second rotating shafts 45 are respectively fixedly connected to a second cylindrical gear 47. A second cylinder 48 is mounted on the frame 1. The second cylinder 48 simultaneously drives two second racks 49 to move up and down. The two second racks 49 mesh with the two second cylindrical gears 47 respectively, thereby driving the two second rotating shafts 45 to rotate in opposite directions. When the two levers 46 rotate downward, they can respectively move one cover plate 201 on the packaging box 20 and restrict the two cover plates 201 to bend and move closer to the middle.

[0045] Both sides of the material handling platform 4 are equipped with can positioning mechanisms 7, and multiple cans 10 are positioned by the can positioning mechanisms 7; a packaging box positioning mechanism 8 is also provided under the material receiving plate 41, and the packaging box 20 is positioned by the packaging box positioning mechanism 8 so that the upper opening of the packaging box 20 corresponds to the discharge port 42.

[0046] Each of the can positioning mechanisms 7 includes a first limiting rod 71 and a second limiting rod 72 disposed on the feeding platform 4. The first limiting rod 71 is parallel to the input direction of the can 10, and the second limiting rod 72 is perpendicular to the input direction of the can 10. The first limiting rod 71, the second limiting rod 72, the can blocking member 21 and the feeding plate 41 together position multiple cans 10.

[0047] The packaging box positioning mechanism 8 includes a third limiting rod 81, a fourth limiting rod 82, a push plate 83, and two second suction cups 84. The third limiting rod 81 is perpendicular to the input direction of the can 10, and the fourth limiting rod 82 is parallel to the input direction of the can 10. The push plate 83, driven by the third cylinder 85, drives one side of the packaging box 20 to move towards the third limiting rod 81. The two second suction cups 84 are mounted on a second suction cup bracket 86. The second suction cup bracket 86, driven by the fourth cylinder 87, moves back and forth in a direction perpendicular to the input direction of the can 10. The two second suction cups 84 suck up the other side of the packaging box 20, causing the other side of the packaging box 20 to move towards the fourth limiting rod 82.

[0048] The feeding platform 4 is equipped with a guard plate 11, which is fixedly connected to the frame 1. The guard plate 11 is parallel to the feeding platform 4, and the distance between the guard plate 11 and the feeding platform 4 is greater than the height of the can 10. The guard plate 11 is used to prevent the can 10 from falling off the feeding platform 4. The first pushing member 43 is provided with a clearance through hole 431, through which the guard plate 11 passes. The guard plate 11 is also provided with multiple observation and maintenance through holes 111 to facilitate observation of the displacement of the can 10 and to facilitate maintenance in case of abnormalities.

[0049] Two positioning cylinders 12 are installed at intervals under the material handling platform 4. The housing of the positioning cylinder 12 can be fixedly connected to the frame 1. Each positioning cylinder 12 drives a positioning component 13 to move up and down. The positioning component 13 is provided with a positioning part 131 parallel to the input direction of the cans 10. The material handling platform is provided with two elongated through holes 14 corresponding to the two positioning components 13. When the positioning component 13 moves upward, the positioning part 131 passes through one of the elongated through holes 14 and protrudes upward from the top of the material handling platform 4 to perform initial positioning on one side of the multiple cans 10. When the positioning component 13 moves downward, the upper end of the positioning part 131 is level with or lower than the upper end surface of the material handling platform 4. In this way, the positioning part 131 initially positions multiple cans 10, which makes it easier for the first pusher 43 to subsequently push multiple rows of cans 10 onto the receiving plate 41. This avoids the need for the first row of cans 10 and the second row of cans 10 to be pushed a long distance, reduces the total moving distance of the first pusher 43, further saves the time required for the process, and improves the packing efficiency.

[0050] The can conveying mechanism 2 includes a first belt conveyor. Two parallel guide rods 22 are provided on the first belt conveyor outside the frame 1. The two guide rods 22 guide the movement of the cans 10. A guard rod 23 is provided between the two guide rods 22 to prevent the cans 10 from jumping off the first belt conveyor.

[0051] The packaging box conveying mechanism 3 includes a second belt conveyor 31, a third belt conveyor 32 and a fourth belt conveyor 33. The second belt conveyor 31 is located below the first belt conveyor. The second belt conveyor 31, the third belt conveyor 32 and the fourth belt conveyor 33 are arranged in parallel to each other. The third belt conveyor 32 and the fourth belt conveyor 33 are respectively located below the material support plates 41 on both sides of the material handling platform 4.

[0052] A second pusher 34 is provided on the second belt conveyor 31. The second pusher 34 moves back and forth along the horizontal and perpendicular input direction of the can 10 under the drive of the fourth drive mechanism 35. When the second pusher 34 moves to one side, it pushes a package 20 onto the third belt conveyor 32. When the second pusher 34 moves to the other side, it pushes a package 20 onto the fourth belt conveyor 33. A transition plate 36 is provided between the second belt conveyor 31 and the third belt conveyor 32 to allow the package 20 to move. A transition plate 36 is provided between the second belt conveyor 31 and the fourth belt conveyor 33 to allow the package 20 to move. The second pusher 34 is provided with a limiting rod perpendicular to the input direction of the can 10. The limiting rod can be designed as an integral part of the third limiting rod 81. The limiting rod restricts the movement of the package 20 along the conveying direction. Preferably, the fourth drive mechanism 35 is a cylinder.

[0053] The output ends of the third belt conveyor 32 and the fourth belt conveyor 33 are connected to a roller conveyor 9. A fifth belt conveyor 91 is connected to the middle of the output end of the roller conveyor 9. A third pusher 92 is mounted on one side of the roller conveyor 9. Driven by a fifth drive mechanism 93, the third pusher 92 moves back and forth horizontally and perpendicularly to the input direction of the cans 10, pushing the packaging boxes 20 delivered from the third belt conveyor 32 to the middle of the roller conveyor 9. A fourth pusher 94 is mounted on the other side of the roller conveyor 9. Driven by a sixth drive mechanism 95, the fourth pusher 94 moves back and forth horizontally and perpendicularly to the input direction of the cans 10, pushing the packaging boxes 20 delivered from the fourth belt conveyor 33 to the middle of the roller conveyor 9. The roller conveyor 9 then pushes the packaging boxes 20 onto the fifth belt conveyor 91. Both the fifth drive mechanism 93 and the sixth drive mechanism 95 are cylinders.

[0054] The front two sides of the roller conveyor 9 are also equipped with blocking brackets 96, which block the packaging box 10 to prevent the packaging box 10 from falling out of the output end of the roller conveyor 9.

[0055] The front end of the can conveying mechanism 2 can also be connected to a screening component 30. The screening component 30 is provided with a screening hole 301 so that cans 10 with incorrect orientation fall out through the screening hole 301, and cans 10 with incorrect orientation are rejected, so as to ensure that the cans 10 entering the can conveying mechanism 2 are all in the same direction.

[0056] In this embodiment, the can 10 moves horizontally into the material handling platform 4 under the drive of the can conveying mechanism 2. The can 10 at the front end is blocked by the can blocking member 21, so that multiple cans 10 are placed close together in the middle of the material handling platform 4.

[0057] The first pusher 43 moves back and forth along the horizontal and perpendicular input direction of the cans 10 under the drive of the second drive mechanism 44. When the first pusher 43 moves to one side, it first pushes five cans 10 to one side of the feeding platform 4 and then obtains initial positioning through the positioning part 131 of the upward-moving positioning member 13. When the first pusher 43 moves to the other side, it pushes five cans 10 to the other side of the feeding platform 4 and obtains initial positioning through the positioning part 131 of the upward-moving positioning member 13 on the other side. Then the first pusher 43 moves back and forth once more. When the first pusher 43 moves to one side again, it pushes two rows of a total of 10 cans 10 onto the two supporting plates 41 on one side of the feeding platform 4 (at this time, the positioning part 131 of the positioning member 13 on that side moves downward back to its original position). When the first pusher 43 moves to the other side again, it also pushes two rows of a total of 10 cans 10 onto the two supporting plates 41 on the other side of the feeding platform 4 (at this time, the positioning part 131 of the positioning member 13 on the other side moves downward back to its original position).

[0058] When there are ten cans 10 on the two support plates 41 on one side of the material handling platform 4, the first suction cup brackets 6 on the two support plates 41 on that side move downward under the drive of the third drive mechanism 62, and the ten first suction cups 61 suck up the ten cans 10 on the two support plates 41; at the same time, the packaging box 20 is fed in by the second belt conveyor 31, and then the second pusher 34 pushes the packaging box 20 onto the third belt conveyor 32 or the fourth belt conveyor 33, so that the packaging box 20 is under the two support plates 41, and the packaging box 20 can be positioned by the packaging box positioning mechanism 8 so that the upper opening of the packaging box 20 corresponds to the discharge port 42;

[0059] Next, the two second rotating shafts 45 rotate in opposite directions, and the two levers 46 respectively move one of the cover plates 201 on the packaging box 20, restricting the two cover plates 201 from bending and converging towards the middle; then, the two material-bearing plates 41 rotate downward in opposite directions and move the other two cover plates 201 on the upper part of the packaging box 20, restricting the other two cover plates 201 from bending and converging towards the middle; then, the first suction cup bracket 6 moves downward again under the drive of the third drive mechanism 62, and the ten first suction cups 61 put the ten cans 10 into the packaging box, and then the first suction cup bracket 6 moves upward back to its original position; then the two material-bearing plates 41 rotate downward in opposite directions, restricting the other two cover plates 201 from bending and converging towards the middle; then, the two material-bearing plates 41 rotate downward in opposite directions, and the other two cover plates 40 move downward in opposite directions, restricting the other two cover plates 201 from bending and converging towards the middle; then, the first suction cup bracket 6 moves downward again under the drive of the third drive mechanism 62, and the ten first suction cups 61 put the ten cans 10 into the packaging box, and then the first suction cup bracket 6 moves upward back to its original position; then the two material-bearing plates 41 move downward in opposite directions, restricting the other two cover plates 201 from bending and converging towards the middle; then, the two material-bearing plates 41 rotate downward in opposite directions, and the other two cover plates 40 ... Plate 41 returns to its original position to receive the next ten cans 10. After repeating the action, the ten first suction cups 61 put the other ten cans 10 into the packaging box 20 to form a second layer. After completion, the packaging box positioning mechanism 8 releases the positioning of the packaging box 20. The packaging box 20 containing multiple layers of cans 10 is then sent to the roller conveyor 9 by the third belt conveyor 32 or the fourth belt conveyor 33. Then, the third pusher 92 or the fourth pusher 94 pushes the packaging box 20 to the middle of the roller conveyor 9. The roller conveyor 9 then pushes the packaging box 20 onto the fifth belt conveyor 91 for delivery.
