Description

Technical Field

[0001] This invention relates to the field of case opener technology, and in particular to a universal intelligent case opener with centered output. Background Technology

[0002] A carton erector, also known as a carton board opening device, is an essential piece of equipment in the product packaging process. The working process of a carton erector is to first open the carton board, then close the bottom cover and convey it to the sealing area for applying tape to the bottom of the carton.

[0003] With the development of cardboard box design technology, its forming has become simpler and simpler. It only requires opening a plate-shaped cardboard box. Since its bottom is composed of four pieces of paper that interlock with each other in sequence, when the cardboard box is opened, the four pieces of paper interlock in sequence to form the bottom of the cardboard box.

[0004] Current carton erecting machines typically only handle one type of carton. When the carton size needs to be changed, manual adjustments are required to the carton compartment, positioning mechanism, bottom closing mechanism, and sealing mechanism. However, packaging companies cannot package only a single product. Changing products necessitates machine adjustments, significantly reducing the company's production efficiency. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a universal intelligent box opener with centered output.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a universal intelligent box opener with central output, including a frame, and further comprising...

[0007] The cardboard box mechanism, located on one side of the frame, is used to hold cardboard boxes;

[0008] The box retrieval mechanism includes two side plates arranged perpendicular to the box storage mechanism and spaced apart. A box retrieval plate is slidably arranged on the side plates, and a number of suction cups are arranged on the side plate of the box retrieval plate adjacent to the box storage mechanism.

[0009] The carton clamping mechanism is located on the side of the frame opposite to the carton storage mechanism. It is used to clamp the carton board into shape and hold the carton tightly.

[0010] A bottom-folding mechanism is located at the middle of the bottom of the frame and is used to close the bottom plate of the carton. The bottom-folding mechanism includes a bottom plate, a first bottom-folding mechanism is fixedly provided on one side of the bottom plate, a second slide rail is provided on the other side of the bottom plate, a second bottom-folding mechanism is slidably provided on the second slide rail, and a third bottom-folding mechanism is provided on the upper sides of both sides of the bottom plate.

[0011] The carton transfer mechanism is used to drive the carton clamping mechanism to move and transport the carton forward.

[0012] The sealing mechanism is used to seal the bottom joint of the carton.

[0013] By adopting the above technical solution, a box storage mechanism, a box retrieval mechanism, a box clamping mechanism, a box moving mechanism, a sealing mechanism, and an adjustable bottom closing mechanism are set. This allows for free adjustment according to the size of different cartons, eliminating the need for manual adjustment. Parameters can be set according to the size of different cartons to achieve the opening of cartons of different sizes.

[0014] Furthermore, the container mechanism includes an inclined container frame. A fixed guide plate is fixedly installed on one side of the container frame, and two first lead screws are rotatably installed on the other side. One end of the two first lead screws is connected by a transmission belt, and the other end of one of the first lead screws is connected to a first motor. First nuts are screwed onto the two first lead screws, and sliding guide plates are installed on the two first nuts. The sliding guide plates are parallel to the fixed guide plate, and a container loading baffle is slidably installed on the container frame along the length direction of the fixed guide plate.

[0015] By adopting the above technical solution, a sliding guide plate is set up, and the first motor drives the first lead screw to rotate, thereby moving the sliding guide plate and adjusting the distance between the sliding guide plate and the fixed guide plate, so as to place cardboard boxes of different sizes.

[0016] Furthermore, two first columns are provided on the side of the frame near the container mechanism. A second lead screw is rotatably installed inside the first column. The bottom ends of the two second lead screws are connected by a transmission belt. A second motor is connected to the top of one of the second lead screws. A second nut is screwed onto the two second lead screws. The bottom sides of the container frame are fixedly connected to the two second nuts respectively.

[0017] By adopting the above technical solution, a first column, a second lead screw, a second motor, and a second nut are set up. The second motor drives the second lead screw to rotate, thereby moving the box rack up and down, thus adjusting the height of the box rack, and then adjusting the height of the cardboard boxes according to different sizes of cardboard boxes.

[0018] Furthermore, a first slide rail is arranged on each of the two side plates, and a sliding frame is slidably mounted on the first slide rail. The two ends of the box-retrieving plate are respectively fixedly connected to the top of the two sliding frames. A third lead screw is rotatably mounted on one side plate. A third motor is connected to one end of the third lead screw, and a third nut is screwed onto the third lead screw. The third nut is fixedly connected to the corresponding sliding frame.

[0019] By adopting the above technical solution, a first slide rail, a sliding frame, a third lead screw, a third motor, and a third nut are set up. The third motor drives the third lead screw to rotate, causing the sliding frame to slide on the first slide rail, thereby driving the box-retrieving plate to move and retrieve the box.

[0020] Furthermore, the first folding mechanism includes a first bracket, on which a first folding bottom plate is hinged via a first hinge axis. A first driving cylinder is disposed within the first bracket, with the cylinder body hinged to the bottom of the first bracket and the end of the telescopic rod hinged to the first folding bottom plate. The first driving cylinder drives the first folding bottom plate to rotate around the first hinge axis. The second folding mechanism includes a second bracket, on which a fourth lead screw is rotatably disposed. One end of the fourth lead screw is connected to a fourth motor. The bottom of the second bracket is helically connected to the fourth lead screw. A second folding bottom plate is hinged on the second bracket via a second hinge axis. A second driving cylinder is disposed within the second bracket, with the cylinder body hinged to the bottom of the second bracket and the end of the telescopic rod hinged to the second folding bottom plate. The second driving cylinder drives the second folding bottom plate to rotate around the second hinge axis. When the first and second folding bottom plates rotate to the horizontal plane, the height of the upper plate edges is the same.

[0021] By adopting the above technical solution, the first folding bottom plate and the second folding bottom plate are driven to rotate around the first hinge axis and the second hinge axis respectively by the first driving cylinder and the second driving cylinder, thereby pushing the two side plates at the bottom of the carton to the middle and closing them together.

[0022] Furthermore, the third folding bottom mechanism includes a base spanning the base plate, on which a third folding bottom plate is hinged via two third hinge shafts. The two third folding bottom plates are symmetrically arranged along the surface of the first folding bottom plate. A third driving cylinder is located inside the base on the outside of the third folding bottom plate. The cylinder body of the third driving cylinder is hinged inside the base, and the end of the telescopic rod is hinged to the third folding bottom plate. A folding bottom tube is provided at the free end of the third folding bottom plate, and the length direction of the folding bottom tube is consistent with the length direction of the base.

[0023] By adopting the above technical solution, two third fold bottom plates are set up. The third drive cylinder drives the third fold bottom plates to rotate around the third hinge axis and close them in the middle, thus completing the bottom closing of the carton.

[0024] Furthermore, the box-moving mechanism includes a mounting plate disposed on the side of the frame opposite to the box-holding mechanism. The mounting plate is provided with a third slide rail and a synchronous belt arranged in the same direction. The length direction of the third slide rail is parallel to the box-holding mechanism. The box-clamping mechanism is slidably disposed on the third slide rail and fixedly connected to the synchronous belt.

[0025] By adopting the above technical solution, a third slide rail and a synchronous belt are set on the mounting plate. By driving the synchronous belt to rotate, the carton clamping frame slides along the third slide rail, thereby conveying the carton out.

[0026] Furthermore, the clamping mechanism includes a sliding seat slidably mounted on a third slide rail, a fourth slide rail mounted on the sliding seat, the length direction of the fourth slide rail being consistent with that of the third slide rail, a first clamping mechanism and a second clamping mechanism slidably mounted on the fourth slide rail, a fifth lead screw rotatably mounted on the sliding seat, one end of the fifth lead screw being connected to a fifth motor, the first clamping mechanism and the second clamping mechanism being helically connected to the fifth lead screw, the first clamping mechanism including a first plate slidably mounted on the fourth slide rail and parallel to the mounting plate, a second plate hinged to the outer side of the first plate, a fourth drive cylinder mounted on the rear side of the first plate, the cylinder body of the fourth drive cylinder being hinged to the rear side of the first plate, and the end of the telescopic rod being connected to the second... The plates are hinged together. The fourth driving cylinder drives the second plate to rotate so that it is parallel or perpendicular to the first plate. The second clamping mechanism includes a sliding bracket slidably mounted on the fourth slide rail. A fifth slide rail perpendicular to the fourth slide rail and a rotatably mounted sixth lead screw are provided on the rear side of the sliding bracket. One end of the sixth lead screw is connected to a sixth motor via a transmission belt. A third plate is slidably mounted on the fifth slide rail. The third plate is helically connected to the sixth lead screw. A fourth plate is hinged to the outer edge of the third plate. A fifth driving cylinder is provided on the rear side of the third plate. The cylinder body of the fifth driving cylinder is hinged to the rear side of the third plate, and the end of the telescopic rod is hinged to the fourth plate. The fifth driving cylinder drives the fourth plate to rotate so that it is parallel or perpendicular to the third plate.

[0027] By adopting the above technical solution and setting up a sliding first clamping mechanism and a second clamping mechanism, it can be used to clamp cartons of different sizes, making it highly adaptable.

[0028] Furthermore, a fixing plate is provided on the outer side of the mounting plate, and a plurality of guide sleeves are provided on the fixing plate. A plurality of guide posts are correspondingly provided on the outer side of the mounting plate. The guide posts and guide sleeves form a sliding guide fit. A drive post is also provided on the outer side of the mounting plate. A drive rod and a drive motor are provided on the fixing plate. The drive rod and the drive post are connected by a transmission mechanism.

[0029] By adopting the above technical solution, a guide sleeve, guide column, drive column, drive rod and drive motor are set, so that the position of the mounting plate can be adjusted, thereby adjusting the position of the carton, so that the bottom seam of the carton is always directly above the bottom closing mechanism.

[0030] Furthermore, it also includes a top limiting mechanism, which includes two second columns mounted on the frame. A seventh lead screw is rotatably mounted inside the second columns. One end of the two seventh lead screws is connected by a transmission belt. The bottom end of one of the seventh lead screws is connected to a seventh motor. A lifting crossbar is mounted between the two second columns. The two ends of the lifting crossbar are respectively helically connected to the two seventh lead screws. A limiting plate is fixedly connected to the bottom of the lifting crossbar. The limiting plate extends towards the bottom closing mechanism.

[0031] By adopting the above technical solution, a top limiting mechanism is set to limit the top of the carton. The seventh motor drives the seventh lead screw to rotate, thereby moving the lifting crossbar up and down to adjust the height of the limiting plate to adapt to cartons of different heights.

[0032] In summary, the present invention has the following beneficial effects: In this application, by setting a box storage mechanism, a box picking mechanism, a box clamping mechanism, a bottom closing mechanism, a box moving mechanism, and a sealing mechanism, wherein the box storage mechanism, the box clamping mechanism, the bottom closing mechanism, and the box moving mechanism are all automatically adjustable structures, so in production, only the size of the carton to be opened needs to be input in advance, and no manual adjustment of the equipment is required. It can be used for cartons of different sizes, has high applicability, and only one machine is needed to meet the customer's opening needs, which greatly reduces the production cost.

[0041] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0042] like Figure 1-9As shown in the figure, this application discloses a universal intelligent carton opener with central output, including a frame 10. The frame 10 is equipped with a carton storage mechanism 20, a carton picking mechanism 30, a carton clamping mechanism 40, a bottom closing mechanism 50, a carton moving mechanism 60, a sealing mechanism 70, and a top limiting mechanism 80. The carton storage mechanism 20 is located on one side of the frame 10 and is used to place cardboard boxes. The carton picking mechanism 30 is used to pick up the cardboard boxes from the carton storage mechanism 20 and move them into the frame 10. The carton clamping mechanism 40 is located on the side of the frame 10 opposite to the carton storage mechanism 20 and is used to clamp the cardboard boxes and hold them tightly. The bottom closing mechanism 50 is located at the middle of the bottom of the frame 10 and is used to close the bottom plate 51 of the carton. The top limiting mechanism 80 is used to limit the top of the carton. The carton moving mechanism 60 is used to drive the carton clamping mechanism 40 to move and transport the carton forward. The sealing mechanism 70 is used to seal the bottom joint of the carton.

[0043] Specifically, the container mechanism 20 includes an inclined container frame 21. A fixed guide plate 22 is fixedly mounted on one side of the container frame 21, and two first lead screws 23 are rotatably mounted on the other side. One end of each first lead screw 23 is connected via a transmission belt 24. The other end of one of the first lead screws 23 is connected to a first motor 25. First nuts 26 are screwed onto both first lead screws 23, and sliding guide plates 27 are mounted on the two first nuts 26, parallel to the fixed guide plate 22. Driving the first lead screws 23 to rotate via the first motor 25 causes the sliding guide plates 27 to move along the direction of the first lead screws 23, thereby adjusting the distance between the sliding guide plates 27 and the fixed guide plate 22. This allows for the placement of cardboard boxes of different lengths and widths. A box-loading baffle 28 is slidably mounted on the container frame 21 along the length of the fixed guide plate 22.

[0044] Since the height of cartons varies depending on their size, two first columns 11 are installed on the side of the frame 10 near the carton storage mechanism 20. A second lead screw 111 is rotatably mounted inside each first column 11. The bottom ends of the two second lead screws 111 are connected via a transmission belt 24. A second motor 112 is connected to the top of one of the second lead screws 111. Second nuts 113 are screwed onto both second lead screws 111. The bottom sides of the carton storage frame 21 are fixedly connected to the two second nuts 113. By driving the second lead screws 111 to rotate via the second motor 112, the carton storage frame 21 can move up and down, thus adjusting the height of the placed cartons to accommodate different sizes.

[0045] The box-retrieving mechanism 30 includes two side plates 31 arranged perpendicularly to the box storage mechanism 20 and spaced apart. A box-retrieving plate 32 is slidably mounted on each side plate 31. Several suction cups are provided on the side plate 31 adjacent to the box storage mechanism 20 on each box-retrieving plate 32, used to hold the cardboard boxes. The two side plates 31 are respectively arranged on both sides of the bottom-closing mechanism 50. A first slide rail 33 is arranged on each side plate 31, and a sliding frame 34 is slidably mounted on the first slide rail 33. Both ends of the box-retrieving plate 32 are fixedly connected to the tops of the two sliding frames 34. A third lead screw 35 is rotatably mounted on one side plate 31. One end of the third lead screw 35 is connected to a third motor 36, and a third nut 37 is screwed onto the third lead screw 35. The third nut 37 is fixedly connected to the corresponding sliding frame 34. The third motor 36 drives the third lead screw 35 to rotate, causing the sliding frame 34 and the box-retrieving plate 32 to move along the first slide rail 33, thereby holding the cardboard boxes on the box storage frame 21 and moving them into the frame 10 for opening.

[0046] The bottom-folding mechanism 50 is an integral structure, fixedly installed at the middle of the bottom of the frame 10. It includes a bottom plate 51, and a first bottom-folding mechanism 52 is fixedly installed on one side of the bottom plate 51. The first bottom-folding mechanism 52 includes a first bracket 521. A first bottom-folding plate 523 is hinged to the first bracket 521 through a first hinge shaft 522. A first driving cylinder 524 is installed inside the first bracket 521. The cylinder body of the first driving cylinder 524 is hinged to the bottom of the first bracket 521, and the end of the telescopic rod is hinged to the first bottom-folding plate 523. The first driving cylinder 524 drives the first bottom-folding plate 523 to rotate around the first hinge shaft 522, pushing the bottom plate 51 of the carton at the bottom of the carton from the vertical direction to the horizontal direction.

[0047] A second slide rail 53 is provided on the other side of the base plate 51. The length direction of the second slide rail 53 is parallel to the box storage mechanism 20. A second bottom folding mechanism 54 is slidably mounted on the second slide rail 53. Specifically, the second bottom folding mechanism 54 includes a second bracket 541. A fourth lead screw 55 is rotatably mounted on the base plate 51. One end of the fourth lead screw 55 is connected to a fourth motor 56. The bottom of the second bracket 541 is screwed to the fourth lead screw 55. By driving the fourth lead screw 55 to rotate through the fourth motor 56, the second bracket 541 can slide along the second slide rail 53, thereby adjusting the position of the second bottom folding mechanism 54 to accommodate cartons of different sizes. A second folding bottom plate 543 is hinged to the second bracket 541 via a second hinge shaft 542. A second driving cylinder 544 is installed inside the second bracket 541. The cylinder body of the second driving cylinder 544 is hinged to the bottom of the second bracket 541, and the end of the telescopic rod is hinged to the second folding bottom plate 543. The second driving cylinder 544 drives the second folding bottom plate 543 to rotate around the second hinge shaft 542, pushing the bottom plate 51 of the carton, which is located in the vertical direction, to the horizontal direction. When the first folding bottom plate 523 and the second folding bottom plate 543 rotate to the horizontal plane, the height of the upper plate edges is the same, thereby ensuring that the bottom of the carton is on the same plane.

[0048] The bottom-closing mechanism 50 also includes a third bottom-folding mechanism 57. The third bottom-folding mechanism 57 includes a base 571 spanning the bottom plate 51. A third bottom-folding plate 573 is hinged to the base 571 via two third hinge shafts 572. The two third bottom-folding plates 573 are symmetrically arranged along the surface of the first bottom-folding plate 523. A third driving cylinder 574 is located inside the base 571 outside the third bottom-folding plate 573. The cylinder body of the third driving cylinder 574 is hinged inside the base 571, and the end of the telescopic rod is hinged to the third bottom-folding plate 573. The third driving cylinder 574 drives the third bottom-folding plate 573 to rotate around the third hinge shafts 572, pushing the bottom plate 51 of the carton from the vertical direction to the horizontal direction. A folding tube 575 is provided at the free end of the third folding bottom plate 573. The length direction of the folding tube 575 is consistent with the length direction of the base 571. The folding tube 575 contacts the carton bottom plate 51 and folds it to the horizontal plane, which can avoid damage to the carton bottom plate 51.

[0049] The first folding mechanism 52 and the second folding mechanism 54 both use plate-shaped first folding plate 523 and second folding plate 543, while the third folding mechanism 57 uses two folding tubes 575. This ensures that there will be no interference during the folding process and guarantees the smooth closing of the bottom.

[0050] The top limiting mechanism 80 includes two second columns 81 mounted on the frame 10. A seventh lead screw 82 is rotatably mounted inside each second column 81. One end of each seventh lead screw 82 is connected via a transmission belt 24. The bottom end of one of the seventh lead screws 82 is connected to a seventh motor 83. A lifting crossbar 84 is positioned between the two second columns 81. Both ends of the lifting crossbar 84 are helically connected to the two seventh lead screws 82. A limiting plate 85 is fixedly connected to the bottom of the lifting crossbar 84, extending towards the bottom closing mechanism 50. The seventh motor 83 drives the seventh lead screw 82 to rotate, causing the lifting crossbar 84 to move up and down, thereby adjusting the height of the limiting plate 85 to accommodate cartons of different sizes. The carton transfer mechanism 60 includes a mounting plate 61 disposed on the side of the frame 10 opposite to the carton storage mechanism 20. A third slide rail 62 and a synchronous belt 63 arranged in the same direction are mounted on the mounting plate 61. The length direction of the third slide rail 62 is parallel to the carton storage mechanism 20. A carton clamping mechanism 40 is slidably mounted on the third slide rail 62 and fixedly connected to the synchronous belt 63. Rotation of the synchronous belt 63 drives the carton clamping mechanism 40 to slide along the third slide rail 62, thereby conveying the opened carton. A fixing plate 12 is disposed on the outer side of the mounting plate 61. Several guide sleeves 121 are disposed on the fixing plate 12, and several guide posts 611 are correspondingly disposed on the outer surface of the mounting plate 61. The guide posts 611 and guide sleeves 121 form a sliding guide engagement. A drive post 612 is also disposed on the outer surface of the mounting plate 61. A drive rod 122 and a drive motor 123 are disposed on the fixing plate 12. The drive rod 122 and the drive post 612 are connected by a transmission mechanism. The drive rod 122 is driven to rotate by the drive motor 123, and the drive column 612 is driven to move by the transmission mechanism, thereby adjusting the position of the mounting plate 61 relative to the fixed plate 12. This allows the position of the carton moving mechanism 60 to be adjusted to accommodate cartons of different sizes.

[0051] The carton clamping mechanism 40 includes a sliding seat 41 slidably mounted on a third slide rail 62. A fourth slide rail 42 is mounted on the sliding seat 41, with its length aligned with that of the third slide rail 62. A first clamping mechanism 43 and a second clamping mechanism 44 are slidably mounted on the fourth slide rail 42. A fifth lead screw 45 is also rotatably mounted on the sliding seat 41. One end of the fifth lead screw 45 is connected to a fifth motor 46. Both the first clamping mechanism 43 and the second clamping mechanism 44 are helically connected to the fifth lead screw 45. The fifth motor 46 drives the fifth lead screw 45 to rotate, thereby moving the first clamping mechanism 43 and the second clamping mechanism 44 to clamp the carton after it has been opened.

[0052] Specifically, the first clamping mechanism 43 includes a first plate 431 slidably mounted on the fourth slide rail 42 and parallel to the mounting plate 61. A second plate 432 is hinged to the outer side of the first plate 431. A fourth driving cylinder 433 is located on the rear side of the first plate 431. The cylinder body of the fourth driving cylinder 433 is hinged to the rear side of the first plate 431, and the end of the telescopic rod is hinged to the second plate 432. The fourth driving cylinder 433 drives the second plate 432 to rotate parallel or perpendicular to the first plate 431. That is, in the initial state, the second plate 432 and the first plate 431 are parallel. After the carton picking mechanism 30 picks up the carton board, it moves the carton board into the frame 10 until the carton board is in contact with the first plate 431. Then, the fourth driving cylinder 433 drives the second plate 432 to rotate perpendicular to the first plate 431, forming a right angle, so that it can fit a corner of the carton.

[0053] The second clamping mechanism 44 includes a sliding bracket 441 slidably mounted on a fourth slide rail 42. A fifth slide rail 442, perpendicular to the fourth slide rail 42, is mounted on the rear side of the sliding bracket 441, along with a rotatably mounted sixth lead screw 443. One end of the sixth lead screw 443 is connected to a sixth motor 444 via a transmission belt 24. A third plate 445 is slidably mounted on the fifth slide rail 442 and is helically connected to the sixth lead screw 443. The sixth motor 444 drives the sixth lead screw 443 to rotate, causing the third plate 445 to slide along the fifth slide rail 442, thereby adjusting the position of the third plate 445. A fourth plate 446 is hinged to the outer edge of the third plate 445. A fifth drive cylinder 447 is mounted on the rear side of the third plate 445. The cylinder body of the fifth drive cylinder 447 is hinged to the rear side of the third plate 445, and the end of the telescopic rod is hinged to the fourth plate 446. The fifth drive cylinder 447 drives the fourth plate 446 to rotate, making it parallel or perpendicular to the third plate 445. In the initial state, the fourth plate 446 and the third plate 445 are parallel. After the carton picking mechanism 30 picks up the carton board, it moves the carton board into the frame 10 until the carton board is in contact with the first plate 431. Then, the fifth drive cylinder 447 drives the fourth plate 446 to rotate so that it is perpendicular to the third plate 445, forming a right angle, thus allowing it to fit a corner of the carton. The right angle formed by the second plate 432 and the first plate 431 is diagonally arranged with the right angle formed by the fourth plate 446 and the third plate 445. In this way, during the inward movement of the two sets of right angles, the carton can be opened and locked in place.

[0054] The operating principle of a general-purpose intelligent carton opener with centered output in this embodiment is as follows: First, the size of the carton to be opened is set, and the positions of each mechanism are adjusted according to the size of the carton. Specifically, the first motor 25 in the carton compartment mechanism 20 drives the first lead screw 23 to rotate and adjust the distance between the sliding guide plate 27 and the fixed guide plate 22; the second motor 112 drives the second lead screw 111 to rotate and adjust the height of the carton compartment frame 21. The fourth motor 56 in the bottom closing mechanism 50 drives the fourth lead screw 55 to rotate and adjust the position of the second bottom folding mechanism 54. The seventh motor 83 in the top limiting mechanism 80 drives the seventh lead screw 82 to rotate and adjust the height of the limiting plate 85. The drive motor 123 in the carton moving mechanism 60 drives the drive rod 122 to rotate and adjust the position of the mounting plate 61. The sixth motor in the carton clamping mechanism 40 drives the sixth lead screw 443 to rotate and adjust the position of the third plate 445. The above adjustments make the machine fit the set carton size perfectly, and the carton is positioned directly above the bottom closing mechanism 50. This eliminates the need to adjust the bottom closing mechanism 50 and the sealing mechanism 70, ensuring that the carton is always output in the center and facilitating connection with subsequent production equipment.

[0055] Then, the cardboard boxes are stacked on the box rack 21. The cardboard box 32 is moved towards the box rack 21, attracting the top cardboard box and then returning to its original position, so that the cardboard box adheres to the first plate 431. The fourth drive cylinder 433 drives the second plate 432 to rotate until it is perpendicular to the first plate 431, blocking the front of the cardboard box. Then, the fifth motor 46 drives the fifth lead screw 45 to rotate, causing the first clamping mechanism 43 and the second clamping mechanism 44 to move towards the center, squeezing the cardboard box towards the center, thus opening the cardboard box to form a carton. Next, the fifth drive cylinder 447 drives the fourth plate 446 to rotate until it is perpendicular to the third plate 445, forming a right angle. At this point, the right angle formed by the second plate 432 and the first plate 431, and the right angle formed by the fourth plate 446 and the third plate 445, tightly hold the carton. Next, the first folding mechanism 52, the second folding mechanism 54, and the third folding mechanism 57 of the bottom-closing mechanism 50 begin to operate, closing the four bottom plates 51 of the carton. The synchronous belt 63 of the carton moving mechanism 60 rotates, which drives the carton clamping mechanism 40 to clamp the carton and move it outward. When the bottom of the carton passes through the sealing mechanism 70, the sealing mechanism 70 sticks tape to the seam at the bottom of the carton, thus completing the opening of a carton.
