[0040] 3. Beneficial effects

[0041] Compared with existing technologies, the advantages of this utility model are:

[0042] (1) In this scheme, when the carton is opened, the storage platform and the feeding mechanism work together to store and supply the carton board. The feeding mechanism uses two conveying methods to move the carton board at the same time, making the movement of the carton board smoother and improving the feeding efficiency of the carton board.

[0043] (2) In this solution, after the cardboard is conveyed, it corresponds to the suction cup module. The board picking mechanism moves the suction cup module to reciprocate by moving the sliding bracket to pick up the cardboard. During the process of the sliding bracket moving the suction cup module, the board picking mechanism moves the sliding bracket by swinging. Under the same moving distance, the board picking mechanism has a shorter stroke than the traditional linear push, which can effectively improve the picking efficiency.

[0044] (3) In this scheme, the board picking mechanism and the box pushing mechanism can adjust the initial position of the sliding bracket and the slide block respectively, so that the picking distance of the suction cup module can adapt to the cardboard of different sizes, and the pushing distance of the box pushing frame can adapt to the cardboard of different sizes. When opening the small cardboard box, the adjusted sliding bracket and the slide block will shorten the travel distance, which can improve the opening efficiency of the small cardboard box.

[0045] (4) In this scheme, after the bottom of the carton is sealed with hot melt adhesive, the two conveying devices will move the carton to the unloading seat and correspond to the pressure plate mechanism. The pressure plate mechanism will press down to make the carton bear force on the unloading seat, so that the bonding between the bottom cover of the carton through hot melt adhesive is more firm and the bonding effect is guaranteed.

[0074] The front cylinder folding module 14 is installed in the fixing frame 13 and corresponds to the rear cylinder folding module 10;

[0075] Height restriction bracket 15 is installed on the upper side of frame 1;

[0076] The baffle assembly 16 is fixedly connected to the height limiting baffle 15 and corresponds to the material storage platform 2;

[0077] The guide plate 17 is fixedly connected inside the frame 1, located on the lower side of the height limiting bracket 15, and corresponds to the fixed bracket 13;

[0078] Hot melt adhesive spraying device 18 is fixedly connected to guide plate 17;

[0079] Two conveying devices 19 are provided, both of which are slidably connected to the frame 1, located on the lower side of the height limiting frame 15 and respectively on both sides of the guide plate 17.

[0080] The base frame 20 has two parts, which are respectively fixedly connected to the bottom ends of the two conveying devices 19;

[0081] Two side cylinder folding cover modules 21 are provided, which are respectively set in two base frames 20 and correspond to the guide plate 17;

[0082] The unloading seat 22 is fixedly connected inside the frame 1, located between the lower side of the height limiting frame 15 and the two conveying devices 19, and corresponds to the guide plate 17;

[0083] Adjustment mechanism 23 is located between frame 1, storage platform 2, height limit frame 15 and two conveying devices 19, and is used to control the movement of storage platform 2, height limit frame 15 and two conveying devices 19;

[0084] The pressure plate mechanism 24 is set on the adjustment mechanism 23 and corresponds to the feeding seat 22, and is used to press down the carton on the feeding seat 22.

[0085] In this embodiment, when opening and sealing the carton, the carton board is first placed vertically on the storage platform 2 for storage. The baffle assembly 16 blocks the carton board, aligning it with the suction cup module 5. The board-grabbing mechanism 6 pushes the sliding bracket 41 to slide on the first fixed rod assembly 4. The sliding bracket 41 drives the suction cup module 5 to move and grasp the carton board. The suction cup module 5 grasps the carton board and moves it into the frame 1. At the same time, the feeding mechanism 3 drives subsequent carton boards to align with the baffle assembly 16. The suction cup module 5 moves into the frame 1 as it moves... During the process, the cardboard board contacts the arc-shaped opening rod 9. The cardboard board automatically unfolds through the arc of the arc-shaped opening rod 9 to form a carton and align with the fixing frame 13 and the slide 8. The rear cylinder folding module 10 at the bottom of the slide 8 folds the rear cover of the bottom of the carton, and the front cylinder folding module 14 in the fixing frame 13 folds the front cover of the bottom of the carton. Then, the pushing mechanism 12 controls the slide 8 to slide on the second fixing rod group 7. The slide 8 pushes the carton between the guide plate 17 and the height limit bracket 15 through the pushing frame 11. The symmetrical sides of the carton are respectively connected to two conveyors. The two conveying devices 19 contact each other, controlling the carton to be conveyed above the guide plate 17. During the conveying process on the guide plate 17, the folded front and rear flaps at the bottom of the carton correspond to the hot melt adhesive spraying device 18. The hot melt adhesive spraying device 18 sprays hot melt adhesive onto the bottom of the carton. Then the carton continues to move, so that the two bottom side flaps correspond to the two base frames 20 respectively. The height limiting bracket 15 restricts the top of the carton, so that the two side cylinder folding flap modules 21 in the two base frames 20 stably fold the two side flaps at the bottom of the carton respectively. The two side flaps pass through The hot melt adhesive sprayed by the hot melt adhesive spraying device 18 is bonded to the bottom of the front and rear covers, so that the bottom of the carton is sealed after it is opened. After the bottom of the carton is sealed, the two conveying devices 19 continue to move the carton, so that the carton is moved to the unloading seat 22 and corresponds to the pressure plate mechanism 24. The pressure plate mechanism 24 presses the carton to make the bonding between the bottom cover of the carton more secure and ensure the bonding effect. The adjusting mechanism 23 can adjust the height of the storage platform 2 and the height limit bracket 15 as well as the distance between the two conveying devices 19, so that the carton opener can adapt to cartons of different specifications.

[0086] Specifically, the feeding mechanism 3 includes a conveying device 31, a rodless cylinder module 32, a pusher frame 33, and a protrusion 34. The conveying device 31 is fixedly connected to the storage platform 2, the rodless cylinder module 32 is fixedly connected to the storage platform 2, the pusher frame 33 is disposed on the rodless cylinder module 32 and is slidably connected to the storage platform 2, and the protrusion 34 is fixedly connected to the storage platform 2 and corresponds to the stop rod assembly 16.

[0087] In this embodiment, when the cardboard is stored in the storage platform 2, it is located on the conveying device 31. The conveying device 31 can transport the cardboard into the frame 1. At the same time, the rodless cylinder module 32 controls the pusher frame 33 to move and push the cardboard, making the movement of the cardboard smoother. When the cardboard corresponds to the protrusion 34 and the stop rod assembly 16, it stops moving and the cardboard stays in the current position to facilitate the suction cup module 5 to grab it.

[0088] Specifically, the plate-taking mechanism 6 includes a first adjusting screw 61, a first cylinder 62, a connecting arm 63, a sliding port 64, and a roller 65. The first adjusting screw 61 is rotatably connected to the frame 1, and the sliding bracket 41 is threadedly connected to the circumferential surface of the first adjusting screw 61. The first cylinder 62 is movably hinged to the frame 1 via a hinge shaft. The connecting arm 63 is movably hinged to the sliding bracket 41 via a hinge shaft, and the output end of the first cylinder 62 is movably hinged to the connecting arm 63 via a hinge shaft. The sliding port 64 is opened on the connecting arm 63. The roller 65 is rotatably connected to the frame 1, and the roller 65 is slidably connected to the sliding port 64.

[0089] In this embodiment, when the suction cup module 5 grips the cardboard, the first cylinder 62 pushes the connecting arm 63. The connecting arm 63 swings through the sliding connection between the sliding port 64 and the roller 65, thereby driving the sliding bracket 41 to slide on the surface of the first fixed rod group 4. The sliding bracket 41 causes the suction cup module 5 to move and grip the cardboard on the storage platform 2. The initial position of the sliding bracket 41 can be adjusted by the first adjusting screw 61, so that the suction cup module 5 can stop at the required position after gripping the cardboard, which can adapt to the opening of cardboard boxes of different sizes. The first cylinder 62 controls the swing of the connecting arm 63 to move the sliding bracket 41. Compared with directly pushing the sliding bracket 41, the extension stroke of the first cylinder 62 is shorter when moving the same distance, which can improve the material picking efficiency.

[0090] Specifically, the pusher mechanism 12 includes a fixed base 121, a second adjusting screw 122, and a second cylinder 123. The fixed base 121 is slidably connected to the frame 1 and is also slidably connected to the second fixed rod group 7. The second adjusting screw 122 is rotatably connected to the frame 1 and the fixed base 121 is threadedly connected to the circumferential surface of the second adjusting screw 122. The second cylinder 123 is fixedly connected to the fixed base 121 and its output end is fixedly connected to the slide block 8.

[0091] In this embodiment, the suction cup module 5 grips the cardboard board and moves it between the slide 8 and the fixed frame 13. During the movement of the cardboard board, it first contacts the arc-shaped opening rod 9. The arc-shaped opening rod 9 causes the cardboard board to unfold and form a cardboard box when it moves between the slide 8 and the fixed frame 13. The rear cylinder folding module 10 and the front cylinder folding module 14 fold the front and rear covers of the bottom of the cardboard box, respectively. Then, the second cylinder 123 pushes the slide 8 on the fixed seat 121, causing the slide 8 to slide on the second fixed rod group 7. The slide 8 drives the pusher frame 11 to push the cardboard guide plate 17 to move. The position of the fixed seat 121 in the frame 1 can be adjusted by the second adjusting screw 122. The slide 8 can change the distance between itself and the fixed frame 13 by connecting to the output end of the second cylinder 123, thereby adapting to cardboard boxes of different sizes.

[0092] Specifically, the adjustment mechanism 23 includes a U-shaped lifting seat 231, a gantry lifting frame 232, and a bidirectional screw adjustment module 233. The U-shaped lifting seat 231 is located on one side of the frame 1, and the storage platform 2 is located inside the U-shaped lifting seat 231. The gantry lifting frame 232 is fixedly connected inside the frame 1, and the height limiting bracket 15 is located inside the gantry lifting frame 232. The bidirectional screw adjustment module 233 is rotatably connected inside the frame 1, and both conveying devices 19 are located on the bidirectional screw adjustment module 233.

[0093] In this embodiment, the height of the storage platform 2 can be adjusted by the U-shaped lifting seat 231, so that the storage platform 2 can adapt to the storage of cardboard boxes of different sizes. The height of the height limiting frame 15 can be adjusted by the gantry lifting frame 232, so that the height limiting frame 15 and the baffle assembly 16 can restrict cardboard boxes of different heights. The bidirectional screw adjustment module 233 is provided with threads in opposite directions. The two conveying devices 19 are respectively threaded to the threads in opposite directions on both sides of the bidirectional screw adjustment module 233. The distance between the two conveying devices 19 can be adjusted by the bidirectional screw adjustment module 233, so that the two conveying devices 19 can convey cardboard boxes of different sizes.

[0094] Specifically, the pressure plate mechanism 24 includes a fixed plate 241, a pressure cylinder module 242, and a pressure box plate assembly 243. The fixed plate 241 is fixedly connected to the gantry lifting frame 232, the pressure cylinder module 242 is fixedly connected to the fixed plate 241, and the pressure box plate assembly 243 is fixedly connected to the output end of the pressure cylinder module 242, and the pressure box plate assembly 243 corresponds to the unloading seat 22.

[0095] In this embodiment, the bottom cover of the carton is moved to the unloading seat 22 after being bonded with hot melt adhesive. The top of the carton corresponds to the pressing plate assembly 243. The pressure cylinder module 242 on the fixing plate 241 controls the pressing plate assembly 243 to press down, so that the carton is subjected to force, thereby improving the bonding effect of sealing the bottom of the carton.

[0096] Specifically, an auxiliary rod assembly 25 is fixedly connected to the pressure plate assembly 243, and the auxiliary rod assembly 25 moves through the fixed plate 241.

[0097] In this embodiment, the auxiliary rod assembly 25 is used to assist the up-and-down movement of the pressure plate assembly 243, so that the movement of the pressure plate assembly 243 remains stable.

[0098] Working principle: When opening and sealing the carton, the carton board is first placed vertically on the storage platform 2. The stop rod assembly 16 and the protrusion 34 cooperate to block the carton board, aligning it with the suction cup module 5. The first cylinder 62 pushes the connecting arm 63, which swings through the sliding connection between the sliding port 64 and the roller 65, thereby causing the sliding bracket 41 to slide on the surface of the first fixed rod assembly 4. The sliding bracket 41 causes the suction cup module 5 to move and grab the carton board on the storage platform 2. After the carton is grabbed, the first cylinder 62 pulls the connecting arm 63 to move the suction cup module 5 back into the frame 1 to reset. The rodless cylinder module 32 controls the pusher frame 33 to move and push the carton. The conveying device 31 transports the subsequent carton boards into the frame 1, making the movement of the carton boards smoother. When the carton board aligns with the protrusion 34 and the stop rod assembly 16 again, it stops moving and remains in its current position for the suction cup module 5 to grasp. As the suction cup module 5 moves into the frame 1, it brings the carton board into contact with the arc-shaped opening rod 9. The carton board automatically unfolds through the arc of the arc-shaped opening rod 9 to form a carton and align with the fixing frame 13 and the slide 8. The rear cylinder folding module 10 at the bottom of the slide 8 folds the rear cover at the bottom of the carton. The front cylinder folding module in the fixing frame 13 folds the rear cover. Group 14 folds the front cover of the bottom of the carton, and then the second cylinder 123 pushes the slide 8 on the fixed seat 121, causing the slide 8 to slide on the second fixed rod group 7. The slide 8 pushes the carton between the guide plate 17 and the height limit bracket 15 through the pusher frame 11. The symmetrical sides of the carton contact the two conveying devices 19 respectively. The two conveying devices 19 control the carton to be conveyed above the guide plate 17. During the conveying of the carton on the guide plate 17, the folded front and rear covers of the bottom of the carton correspond to the hot melt adhesive spraying device 18. The hot melt adhesive spraying device 18 sprays hot melt adhesive on the bottom of the carton. Then the carton continues to move, so that the two bottom side covers correspond to the two base frames 20 respectively. The height-limiting baffle 15 restricts the top of the carton, and the two side cylinder folding modules 21 in the two base frames 20 stably fold the two side covers at the bottom of the carton. The two side covers are bonded to the bottom of the front and rear covers by hot melt adhesive sprayed by the hot melt adhesive spraying device 18, so that the bottom of the carton is sealed after the carton is opened. After the bottom of the carton is sealed, the two conveying devices 19 continue to move the carton, so that the carton is moved to the unloading seat 22 and corresponds to the pressing plate assembly 243. The pressure cylinder module 242 on the fixing plate 241 controls the pressing plate assembly 243 to press down. The pressing plate assembly 243 presses the carton, making the bonding between the bottom covers of the carton more firm and ensuring the bonding effect.

[0099] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
