Description

Technical Field

[0001] This utility model relates to the field of case opener technology, and more specifically, to a high-speed case opener. Background Technology

[0002] A carton erector, also known as a carton forming machine, is an automated packaging equipment that integrates automatic carton opening, automatic bottom folding, and automatic sealing of the bottom of the carton. Its main function is to automatically open the folded cardboard boxes, fold the bottom according to a specific program, seal them with tape (or hot melt glue), and then transport them to the subsequent packing stage.

[0003] Currently, existing carton opening machines involve multiple steps of sequential folding when opening cartons. First, the machine moves to pick up the material to open the carton, then folds the front and back flaps, then the two side flaps, and finally seals the bottom by moving the machine to contact the sealing device. These multiple flap folding actions and the moving material picking and feeding are performed separately, resulting in low work efficiency. Utility Model Content

[0019] 3. Beneficial effects

[0020] Compared with existing technologies, the advantages of this utility model are:

[0021] (1) In this scheme, when opening the carton, the two feeding boxes feed the carton board through two lifting mechanisms. The drive mechanism drives the linkage mechanism to make the feeding rack reciprocate to pick up the material. The feeding rack and the rear pusher reciprocate in an alternating manner through the lower transmission component. After the feeding rack picks up the material, the rear pusher receives the material. During the picking up and receiving process, the linkage mechanism makes the opening mechanism, the rear folding mechanism and the lower folding plate work synchronously. The opening mechanism cooperates with the positioning mechanism to open the carton board. During the opening process, the rear folding mechanism folds the rear cover, the front folding mechanism cooperates with the rear folding mechanism to fold the front cover, and the upper folding mechanism folds the upper cover. After the cover is folded, the feeding rack and the rear pusher continue to move to pick up and receive the material, which will cause the two lower elastic pusher blocks to push the carton. The two upper elastic pusher blocks on the upper side follow the two through the synchronization mechanism respectively. The lower elastic pusher blocks push the cartons in an alternating pattern, feeding them out of the carton opener. During feeding, the cartons pass sequentially through the lower folding plate and the tape sealer. The lower folding plate reciprocates to fold the bottom cover of the carton, and with the help of the guide plate, the carton is kept in a stable folded state as it moves toward the tape sealer. The tape sealer is adjusted to the required height by the lifting mechanism to seal the bottom of the carton, thus completing the entire carton opening process. This high-speed carton opener uses a drive mechanism to drive a linkage mechanism, enabling the carton conveying, opening, folding the back cover, and folding the bottom cover to work in coordination. The opening steps are tightly connected, greatly improving the opening speed. Moreover, while opening the carton and folding the back cover, the front folding mechanism folds the front cover and the upper folding mechanism folds the top cover, further increasing the opening speed and effectively ensuring work efficiency.

A synchronization mechanism 21 is provided between one upper pusher 18 and the feeding rack 13. The synchronization mechanism 21 is used to drive one upper pusher 18 to move synchronously with the feeding rack 13. A lower fixed frame 22 is fixedly connected inside the frame 1. A positioning mechanism 23 is provided inside the lower fixed frame 22, and the positioning mechanism 23 and the folding cover fixing plate 12 are used for positioning during the carton opening process. The lower fixed frame 22 also has... The box opening mechanism 24 corresponds to the positioning mechanism 23. The box opening mechanism 24 is used to grip the carton board for opening. A front folding mechanism 25 is provided on the lower fixed frame 22, and the front folding mechanism 25 corresponds to the box opening mechanism 24. The front folding mechanism 25 is used to fold the front cover of the carton. A rear folding mechanism 26 is provided on the lower fixed frame 22, and the rear folding mechanism 26 corresponds to the front folding mechanism 25. The rear folding mechanism 26 is used to fold the rear cover of the carton. An upper folding mechanism 33 is provided on the upper baffle 10, and the upper folding mechanism 33 corresponds to the box opening mechanism 24. The upper folding mechanism 33 is used to fold the top cover of the carton. A lower folding plate 27 is movably hinged to one side of the cover fixing plate 12 via a hinge shaft. A guide plate 34 is fixedly connected to the upper baffle 10, and the guide plate 34 corresponds to the lower folding plate 27.A drive mechanism 28 is installed inside the frame 1, and a linkage mechanism 29 is installed on the lower fixed frame 22. The drive mechanism 28 drives the linkage mechanism 29 to operate the feeding frame 13, the rear push frame 15, the box opening mechanism 24, the rear folding mechanism 26, and the lower folding plate 27. A tape sealer 30 is installed inside the frame 1, and the tape sealer 30 corresponds to the lower folding plate 27. A lifting mechanism 31 is installed inside the frame 1 to adjust the position of the tape sealer 30 relative to the bottom of the carton.

[0041] Each lifting mechanism 8 includes an inner fixed frame 81, two lifting cylinders 82, two lifting rods 83, two telescopic cylinders 84, two sliding frames 85, and two sets of insert rod assemblies 86. The inner fixed frame 81 is fixedly connected to a feeding box 3. The two lifting cylinders 82 are fixedly connected to the inner fixed frame 81. The two lifting rods 83 are slidably connected to the inner fixed frame 81, and the output ends of the two lifting cylinders 82 are fixedly connected to the two lifting rods 83. The two telescopic cylinders 84 are fixedly connected to the two lifting rods 83. The two sliding frames 85 are fixedly connected to the output ends of the two telescopic cylinders 84. The two sets of insert rod assemblies 86 are fixedly connected to the two sliding frames 85, and the two sets of insert rod assemblies 86 slide through the two lifting rods 83 and move through to one side of a feeding box 3.

[0042] In this embodiment, the distance between the two feeding boxes 3 is adjusted by the screw drive adjusting component 2, allowing the two feeding boxes 3 to accommodate cardboard boxes of different sizes. Simultaneously, the long guide component 4 and the short guide slide 5 follow the adjustment of the two feeding boxes 3 to accommodate cardboard boxes of different sizes. By adjusting the position of the adjustable limiting component 7, which works in conjunction with the fixed limiting plate 6, cardboard boxes of different sizes are smoothly placed between the two feeding boxes 3. When opening the cardboard boxes, the fixed limiting plate 6 and the adjustable limiting component 7 place the stacked cardboard boxes between the two feeding boxes 3 on the long guide component 4 and the short guide slide 5. The lifting mechanism 8 inside each feeding box 3 controls the movement of four sliding frames 85 via four telescopic cylinders 84, and the four sliding frames 85 drive four sets of... The insertion rod assembly 86 slides through the two feeding boxes 3 within the four lifting rods 83. After passing through the two feeding boxes 3, the four sets of insertion rod assemblies 86 are inserted into the stacked cardboard boxes. The four lifting cylinders 82 pull the four lifting rods 83 to slide on the two inner fixing frames 81 respectively. The four lifting rods 83 drive the four sets of insertion rod assemblies 86 to lift the stacked upper cardboard boxes, so that the bottom cardboard box remains in the long guide assembly 4 and the short guide slide 5. The drive mechanism 28 drives the feeding rack 13 to slide back and forth in the frame 1 through the control linkage mechanism 29. The feeding rack 13 uses the first suction cup assembly 14 to repeatedly grab the bottom cardboard box, so that the cardboard box enters the frame 1 through the long guide assembly 4 and the short guide slide 5 and corresponds to the rear push frame 15. The crease at the bottom of the cardboard box is located at... On the folding and fixing plate 12, each time the feeding rack 13 reciprocates to grab the carton board, the lower transmission assembly 32 drives the rear pusher 15 to reciprocate in an alternating manner. The rear pusher 15 grabs the carton board fed by the receiving feeding rack 13 through the second suction cup assembly 16, causing the bottom cover of the carton board to move to correspond with the positioning mechanism 23. The positioning mechanism 23 adsorbs and fixes the bottom cover of the carton board. At the same time, the feeding rack 13 and the rear pusher 15 continue to reciprocate. The linkage mechanism 29 causes the opening mechanism 24 and the rear folding mechanism 26 to reciprocate. The opening mechanism 24 first opens the carton board, the rear folding mechanism 26 folds the rear cover of the carton, the front folding mechanism 25 folds the front cover of the carton, and the upper folding mechanism 33 folds the top cover of the carton. After the carton is opened and folded, the feeding rack 13 and the rear pusher 15 continue to move. The movement causes the two sets of elastic lower pusher blocks 17 to alternately push the carton across the flap fixing plate 12 and the long guide assembly 4. Additionally, the feeding frame 13 drives an upper pusher 18 via a synchronization mechanism 21. The two upper pushers 18, via the upper transmission assembly 20, follow the feeding frame 13 and the rear pusher 15 in an alternating reciprocating motion. This causes the two upper elastic pusher blocks 19 on the upper side to push the carton against the two lower elastic pusher blocks 17 on the lower side. The side baffle assembly 11 blocks the other end of the carton, ensuring smooth pushing. During the pushing process, the carton passes sequentially through the lower folding plate 27 and the tape sealer 30. The linkage mechanism 29 causes the lower folding plate 27 to reciprocate, folding the flap of the passing carton. Simultaneously, the guide plate 34 blocks the top flap of the carton.The entire unpacking process involves keeping all bottom flaps of the carton folded, then sealing the bottom with a tape sealer 30. The tape sealer 30 has a lifting mechanism 31 at its bottom, which adjusts its height to accommodate different carton sizes. The upper baffle 10, with its adjustable height via a screw-lift assembly 9, restricts the carton from above, ensuring stable transport of cartons of varying sizes. Both lower and upper elastic push blocks 17 and 19 are elastic; when moving forward, they are compressed by the inclined plane, preventing movement, and when moving backward, they are pushed by the plane, ensuring stable transport.

[0043] Specifically, the synchronization mechanism 21 includes a fixed slide plate 211 and a fixed column 212. The fixed slide plate 211 is fixedly connected to the feeding rack 13, and the fixed column 212 is fixedly connected to an upper push frame 18. The fixed column 212 is slidably connected to the outer surface of the fixed slide plate 211.

[0044] In this embodiment, the feeding rack 13 moves, driving the fixed slide plate 211 to move. The fixed slide plate 211 drives an upper pusher 18 to move via a fixed column 212. The two upper pushers 18 correspond to the feeding rack 13 and the rear pusher 15, respectively. The upper transmission assembly 20 can move synchronously with the rear pusher 15 and the feeding rack 13, respectively, so that the two upper elastic pusher blocks 19 push the carton from the top. The fixed column 212 is slidably connected to the fixed slide plate 211 and will not affect the height adjustment of the upper baffle 10.

[0045] Specifically, the positioning mechanism 23 includes a lifting cylinder 231 and a lower suction cup assembly 232. The lifting cylinder 231 is fixedly connected to the lower fixed frame 22, and the lower suction cup assembly 232 is fixedly connected to the output end of the lifting cylinder 231. The lower suction cup assembly 232 is located on one side of the folding cover fixing plate 12.

[0046] In this embodiment, the rear pusher 15 slides the carton board on the folding cover fixing plate 12 through the second suction cup assembly 16. When the lower cover of the carton board corresponds to the lower suction cup assembly 232 during the movement, the second suction cup assembly 16 cancels the suction of the carton board, and the lifting cylinder 231 controls the lower suction cup assembly 232 to rise, suction and hold the lower cover of the carton board, so that the carton board remains stable and easy to open.

[0047] Specifically, the unpacking mechanism 24 includes two parallel rotating rods 241, a connecting universal ball joint rod 242, and an upper suction cup assembly 243. The two parallel rotating rods 241 are rotatably connected to the lower fixed frame 22 and are arranged in parallel. The connecting universal ball joint rod 242 is movably hinged between the two parallel rotating rods 241.

[0058] In this embodiment, the output end of the drive motor 282 is fixedly connected to the sprocket and chain transmission assembly 2912. The sprocket and chain transmission assembly 2912 causes the cam rod 293 to rotate. The auxiliary rod 292 assists the transmission of the sprocket and chain transmission assembly 2912, ensuring the stability of the cam rod 293 when driven by the sprocket and chain transmission assembly 2912. When the cam rod 293 rotates, it causes the cam assembly 294 and the linkage arm 2913 to rotate. The linkage arm 2913 drives the reciprocating swing arm 2915 to reciprocate within the frame 1 via the reciprocating universal ball joint rod 2914. The reciprocating swing arm 2915 drives the feeding frame 13 to reciprocate within the frame 1 via the material-picking universal ball joint rod 2916. Simultaneously, three... Tension springs 298 respectively pull the lower folding arm 2917, the rear folding arm 295, and the box opening arm 296, causing three rollers 297 to press against the cam assembly 294.

The lower folding arm 2917, the rear folding arm 295, and the box opening arm 296 respectively cause the lower folding universal ball joint rod 2911, the box opening universal ball joint rod 299, and the rear folding universal ball joint rod 2910 to push and pull the lower folding plate 27, the eccentric arm 261, and a parallel rotating rod 241 to reciprocate, thereby causing the rear folding mechanism 26, the box opening mechanism 24, and the lower folding plate 27 to open the carton and fold the lid, respectively.

[0059] Specifically, the lifting mechanism 31 includes a fixed sliding sleeve assembly 311, a sliding rod assembly 312, a threaded sleeve 313, a threaded rod 314, an adjusting rod 315, a driving bevel gear 316, and a driven bevel gear 317.

The threaded sleeve 313 is fixedly connected to the frame 1. The threaded rod 314 is threadedly connected to the threaded sleeve 313, and the top end of the threaded rod 314 is rotatably connected to the bottom end of the tape sealer 30. The adjusting rod 315 is rotatably connected to the bottom of the tape sealer 30. The driving bevel gear 316 is fixedly connected to one end of the adjusting rod 315. The driven bevel gear 317 is fixedly connected to the circumferential surface of the threaded rod 314, and the driven bevel gear 317 meshes with the driving bevel gear 316.

[0060] In this embodiment, after the carton is folded, it passes through the tape sealer 30. The driving bevel gear 316 rotates via the adjusting rod 315. The driving bevel gear 316 causes the threaded rod 314 to rotate within the threaded sleeve 313 via the driven bevel gear 317. The threaded rod 314 adjusts the height of the tape sealer 30 by threading up and down within the threaded sleeve 313, allowing the tape sealer 30 to adapt to sealing cartons of different sizes. When the height of the tape sealer 30 is adjusted, it will drive the sliding rod assembly 312 to slide within the fixed sliding sleeve assembly 311 to ensure the stability of the adjustment.

[0061] Working principle: When opening the carton, the stacked cartons are placed between two loading boxes 3 on the long guide assembly 4 and the short guide slide 5 by the fixed limit plate 6 and the adjustable limit assembly 7. The two telescopic cylinders 84 in each loading box 3 control the movement of four sliding frames 85. The four sliding frames 85 drive four sets of insertion rod assemblies 86 to slide through the two loading boxes 3 in the four lifting rods 83. After passing through the two loading boxes 3, the four sets of insertion rod assemblies 86 are inserted into the stacked cartons. The four lifting cylinders 82 pull the four lifting rods 83 to slide on the two inner fixed frames 81 respectively. The four lifting rods 83 drive the four sets of insertion rod assemblies 86 to lift the upper layer of stacked cartons, so that the bottom carton remains in the long guide assembly 4 and the short guide slide. Inside frame 1, the output end of drive motor 282 is fixedly connected to sprocket and chain transmission assembly 2912. The sprocket and chain transmission assembly 2912 causes cam rod 293 to rotate. When cam rod 293 rotates, it causes cam assembly 294 and linkage arm 2913 to rotate. Linkage arm 2913 drives reciprocating swing arm 2915 to reciprocate within frame 1 via reciprocating universal ball joint 2914. Reciprocating swing arm 2915 drives feeding rack 13 to reciprocate within frame 1 via material picking universal ball joint 2916. Feeding rack 13 reciprocates by gripping the bottom cardboard board via first suction cup assembly 14, causing the cardboard board to enter frame 1 through long guide assembly 4 and short guide slide 5, corresponding to the rear push frame 15. The crease at the bottom of the cardboard board is located on the folding cover fixing plate. On step 12, each time the feeding rack 13 reciprocates to grab a cardboard box, the lower transmission assembly 32 drives the rear pusher 15 to reciprocate in an alternating manner. The rear pusher 15 grabs the cardboard box fed by the receiving feeding rack 13 through the second suction cup assembly 16, causing the lower cover of the cardboard box to move to correspond with the lower suction cup assembly 232. The second suction cup assembly 16 then releases its suction on the cardboard box, and the lifting cylinder 231 controls the lower suction cup assembly 232 to rise, holding the lower cover of the cardboard box in place to keep the cardboard box stable. At the same time, three tension springs 298 respectively pull the lower folding arm 2917, the rear folding arm 295, and the opening arm 296, causing the three rollers 297 to press against the cam assembly 294. The cam assembly 294, through the three rollers 297, causes the lower folding arm 2917 and the rear folding arm 296 to move in opposite directions. 5. The inner rotating rod 291 rotates, and the opening arm 296 rotates within the lower fixed frame 22. The lower folding arm 2917, the rear folding arm 295, and the opening arm 296 respectively cause the lower folding universal ball joint rod 2911, the opening universal ball joint rod 299, and the rear folding universal ball joint rod 2910 to push and pull the lower folding plate 27, the eccentric arm 261, and a parallel rotating rod 241 to reciprocate. Another parallel rotating rod 241 rotates parallel through a linkage universal ball joint rod 242. The two parallel rotating rods 241 rotate synchronously on the lower fixed frame 22, thereby driving the upper suction cup assembly 243 to rotate and lift in a horizontal state. During the lifting and lowering process of the upper suction cup assembly 243, it suctions and opens the carton. The eccentric arm 261 then reciprocates, driving the rotating rod 262 to reciprocate on the lower fixed frame 22.The rotating rod 262 causes the rear folding plate 264 to reciprocate via the synchronizing rod 263. The rear folding plate 264 folds the rear cover of the carton. The side push cylinder 251 pushes the front folding rod 252 to rotate on the lower fixed frame 22. The front folding rod 252 folds the front cover of the carton. The lower push cylinder 331 pushes the upper folding plate 332 to rotate downward on one side of the upper baffle 10. The upper folding plate 332 folds the top cover of the carton. After the carton is opened and folded, the feeding rack 13 and the rear push frame 15 continue to move, causing the two sets of elastic lower elastic pusher blocks 17 to alternately push the carton to slide on the folding fixing plate 12 and the long guide assembly 4. In addition, during the movement of the feeding rack 13, the fixed slide plate 211 moves. The fixed slide plate 211 is fixed by a fixed... Column 212 drives an upper pusher 18 to move. The two upper pushers 18 correspond to the feeding frame 13 and the rear pusher 15 respectively. Through the upper transmission assembly 20, they follow the feeding frame 13 and the rear pusher 15 in an alternating reciprocating motion, causing the two upper elastic pusher blocks 19 on the upper side to correspond to the two lower elastic pusher blocks 17 on the lower side, pushing the carton. The side baffle assembly 11 blocks the other end of the carton, keeping the pushing of the carton smooth. During the pushing process, the carton passes through the lower folding plate 27 and the tape sealer 30 in sequence. The lower folding plate 27 reciprocates to fold down the carton's lid, while the guide plate 34 blocks the top lid of the carton, keeping all the bottom lids of the carton in the folded state. Then, the tape sealer 30 seals the bottom, completing the entire opening process.
