The tape opening mechanism is installed on the feeding mechanism 2, and is used to cut the tapes at the upper and lower sealing ports of the carton conveyed on the feeding mechanism 2. Specifically, the feeding mechanism 2 includes a first feeder, and the first feeder can be a roller conveyor. The tape opening mechanism includes two clamping conveyor belts 22 and two cutting knives 23. The two clamping conveyor belts 22 are horizontally symmetrically installed on both sides of the first feeder. When the carton filled with materials is conveyed on the first feeder, the clamping conveyor belts 22 on both sides can clamp the two sides of the carton and convey it forward, providing sufficient power for the carton tape opening. The two cutting knives 23 are fixedly installed on the first feeder symmetrically up and down and correspond to the tapes at the upper and lower sealing ports of the carton. Specifically, the upper cutting knife 23 is fixed in the middle of the roller conveyor through a portal frame, and the lower cutting knife 23 is fixed in the middle of the roller conveyor.

[0022] The cartons containing materials are placed on the first conveyor 21 and arranged with the sealed openings of the tape in the front-to-back direction. When the first conveyor 21 feeds the materials, the left and right clamping conveyor belts 22 clamp the cartons and convey them forward. The tapes at the sealed openings on the upper and lower surfaces of the cartons will be cut by the upper and lower cutting knives 23, thereby realizing the rapid cutting operation of the tape.

[0023] The feeding mechanism 2 is connected to the cover opening mechanism 3, and the cover opening mechanism 3 is used to open the carton cover at the top of the carton. Figure 4 As shown, the cover opening mechanism 3 includes a second feeder, a lifting drive mechanism 32 and a cover opening assembly. The table 11 of the machine body 1 is provided with a material port 110. The second feeder is arranged below the material port 110 and is movable up and down. The second feeder is horizontally connected to the tail of the first feeder. The second feeder can also adopt a roller conveyor structure. The second feeder is installed on the lifting part of the lifting drive mechanism 32. The lifting drive mechanism 32 can adopt the structure of the motor driving the chain to drive up and down in the prior art. The second feeder is installed on a vertical slide rail and then fixedly connected to the chain. The second conveyor 31 can be lifted and lowered by the chain action.

[0024] The opening of the carton is generally a four-sided folding structure, and the front and rear folded edges are folded toward the middle and then the left and right folded edges are folded to achieve the sealing of the opening, and the left and right folded edges are in the upper layer, and the front and rear folded edges are in the lower layer. The cover opening assembly of the device is installed at the upper material opening 110, and the cover opening assembly includes two first cover openers 33 and two second cover openers 34. The two first cover openers 33 are symmetrically arranged on the left and right sides of the material opening 110, and are used to open the two folding covers on the upper layer of the carton. The two second cover openers 34 are symmetrically arranged on the front and rear sides of the material opening 110, and are used to open the two folding rods on the lower layer of the carton.

[0025] Specifically, Figure 5 As shown, the first cover opener 33 includes a moving plate 331, a first telescopic cylinder 337, a first movable plate 332, and a first negative pressure suction nozzle 333. The moving plate 331 is horizontally slidably installed on the table 11. The table 11 is provided with a first horizontal driving component for driving the moving plate 331 to move horizontally. The first horizontal driving component includes a lead screw 35 driven by a motor. The lead screw 35 is horizontally installed on the table 11. The moving plates 331 of the two first cover openers 33 are respectively threadedly sleeved on the positive and negative threads on both sides of the lead screw 35. The first negative pressure suction nozzle 333 is mounted on the first movable plate 332 and connected to the external negative pressure source. One end of the first connecting rod 334 is vertically fixedly connected to the lower front and rear sides of the first movable plate 332. The other end of the first connecting rod 334 is vertically fixedly connected to a rotating shaft 335. The rotating shaft 335 is horizontally rotatably mounted on the movable plate 331. One end of the second connecting rod 336 is also vertically fixedly connected to one of the rotating shafts 335. The other end of the second connecting rod 336 is rotatably connected to the piston rod of the first telescopic cylinder 337. The tail of the first telescopic cylinder 337 is rotatably connected to the movable plate 331. The first telescopic cylinder 337 adopts a cylinder structure.

[0026] When the left and right first cover openers 33 are in action, the lead screw 35 rotates to drive the two movable plates 331 sleeved on the positive and negative threads to move synchronously close to the material opening 110, and then the first telescopic cylinder 337 extends, and the second connecting rod 336 drives the rotating shaft 335, the first connecting rod 334 and the first movable plate 332 to flip, so that the first negative pressure suction nozzles 333 on the two first movable plates 332 are driven by negative pressure to suck the left and right folded edges above the carton respectively; the first telescopic cylinder 337 is driven to contract, driving the rotating shaft 335, the first connecting rod 334 and the first movable plate 332 to reset in the opposite direction, so that the left and right folded edges of the carton can be opened, thereby realizing the rapid opening operation of the carton.

[0027] like Figure 6 As shown, the second cover opener 34 includes a horizontal telescopic cylinder 341, a vertical telescopic cylinder 343, a fixed plate 342, a second movable plate 344, a third connecting rod 345 and a second negative pressure suction nozzle 346. The horizontal telescopic cylinder 341 is horizontally installed at the material inlet 110, the fixed plate 342 is fixedly connected to the piston rod of the horizontal telescopic cylinder 341, the vertical telescopic cylinder 343 is vertically installed on the fixed plate 342, and the second negative pressure suction nozzle 346 connected to the external negative pressure source is installed on the second movable plate 344. The lower part of the second movable plate 344 is rotatably connected to the piston rod of the vertical telescopic cylinder 343, and the two ends of the third connecting rod 345 are rotatably connected to the middle part of the second movable plate 344 and the upper part of the fixed plate 342. The horizontal telescopic cylinder 341 and the vertical telescopic cylinder 343 both adopt a cylinder structure.

[0028] When the front and rear second cover openers 34 are in motion, the horizontal telescopic cylinder 341 extends, driving the vertical telescopic cylinder 343, the fixed plate 342, the second movable plate 344, etc. to approach the front and rear side walls of the carton, and then drives the vertical telescopic cylinder 343 to extend upward. Under the pulling action of the third connecting rod 345, the second movable plate 344 will flip toward the side of the carton, so that the two second negative pressure suction nozzles 346 are driven by negative pressure to suck the front and rear folded edges of the lower layer at the upper opening of the carton. By utilizing the contraction of the vertical telescopic cylinder 343, the second movable plate 344, the third connecting rod 345 and the second negative pressure suction nozzle 346 are driven to flip and reset in the opposite direction, so that the front and rear folded edges can be flipped open, thereby realizing the rapid opening operation of the carton.

[0029] like Figure 7 As shown, the feeding mechanism is installed above the machine body 1, and is used to take out the materials in the carton and send them to the unloading mechanism 6, and send the empty carton after taking out the materials to the carton folding mechanism 5. Specifically, the feeding mechanism includes a synchronous belt truss 4 and a material grabbing suction cup 41, the synchronous belt truss 4 is installed above the machine body 1, and the material grabbing suction cup 41 is installed at the bottom of the manipulator below the synchronous belt truss 4.

[0030] The synchronous belt truss 4 can move horizontally on the machine body 1 along the X-axis and Y-axis directions, and the movement in the z-axis direction can realize the vertical lifting of the manipulator. Its structural principle is the existing technology and will not be repeated here. The material grabbing suction cup 41 can adopt the sponge suction cup structure in the existing technology, which can realize the stable grabbing of materials.

[0031] After the cover opening mechanism 3 opens the cover on the top of the carton, the synchronous belt truss 4 drives the material grabbing suction cup 41 to take out the materials in the carton layer by layer and place them on the unloading mechanism 6 (which can adopt a chain plate conveyor belt structure) on one side of the machine body 1, and then send them to the next process by the unloading mechanism 6. When all the materials in the carton are taken out, the material grabbing suction cup 41 is also used to extend into the carton to suck the bottom surface of the carton and grab the carton to send it to the carton folding mechanism 5. This device can realize the rapid transportation of materials and empty cartons by the action of the feeding mechanism, which significantly improves the material transmission efficiency.

[0032] like Figure 8-10As shown, the carton folding mechanism 5 is used to fold and store empty cartons. The carton folding mechanism 5 is arranged in the carton storage area on the machine body 1. The carton folding mechanism 5 includes a third movable plate 51, a second telescopic cylinder 56, a push plate 52 and a second horizontal driving assembly 53. The third movable plate 51 and the push plate 52 are arranged on one side of the carton storage area in a vertical state when not in operation. The edge of the third movable plate 51 is rotatably connected to the machine body 1, and the tail of the second telescopic cylinder 56 is rotatably connected to the machine body 1. The piston rod of the second telescopic cylinder 56 is rotatably connected to the middle part of the third movable plate 51, which is used to drive the third movable plate 51 to flip in the horizontal direction toward the push plate 52 side. The second horizontal driving assembly 53 is horizontally installed perpendicular to the push plate 52, and the push plate 52 is connected to the action end of the second horizontal driving assembly 53. A material unloading station is provided on the side of the carton storage area 12 away from the third movable plate 51, which is used to take out the stacked empty carton pieces.

[0033] The third negative pressure nozzle 55 connected to the external negative pressure source is installed on the movable plate and the push plate 52. The second telescopic cylinder 56 can adopt a cylinder structure, and the second horizontal drive assembly 53 can adopt the same structure as the above-mentioned lifting drive mechanism 32, that is, a structure in which the motor drives the chain transmission to drive the push plate 52 to move horizontally. A limit plate 54 is also horizontally provided on the body 1 above the carton storage area, which is used to limit the push plate 52 when it pushes the carton sheet to move.

[0034] When the carton folding mechanism 5 is operating, the material grabbing suction cup 41 on the synchronous belt truss 4 sucks the bottom of the empty carton and places the empty carton between the third movable plate 51 and the push plate 52 at a certain height from the bottom of the carton storage area, and the carton is sucked by the third negative pressure suction nozzle 55 on the movable plate and the push plate 52. Then, the material grabbing suction cup 41 on the synchronous belt truss 4 continues to move downward, and after the four folded edges at the bottom of the carton are poked downward, the material grabbing suction cup 41 is reset upward; then the second telescopic cylinder 56 extends, driving the third movable plate 51 to flip toward the push plate 52 side, thereby squeezing the carton into a sheet. After the second telescopic cylinder 56 drives the third movable plate 51 to reset in the opposite direction, the second horizontal drive assembly 53 drives the push plate 52 to move to the side of the unloading station, thereby pushing the sheet-like cartons to the unloading station for stacking and storage, which is convenient for the subsequent centralized recycling of empty cartons.

[0035] When the device is used, the carton containing materials is placed on the first feeder for transportation. Under the clamping and conveying of the clamping conveyor belt 22, the tapes at the upper and lower sealing openings of the carton will be cut by the cutter 23; then the carton is transported to the second conveyor 31, and the lifting drive mechanism 32 lifts the carton on the second conveyor 31 to the material opening 110; the lead screw 35 is driven to rotate, so that the two first cover openers 33 approach the left and right sides of the carton and then move to open the left and right folds of the opening above the carton; then the two second cover openers 34 are moved to open the front and rear folds of the carton opening; the synchronous belt truss 4 is used to drive the movement of the material grabbing suction cup 41 to take out the materials in the carton layer by layer and place them for unloading On the mechanism 6; when all the materials in the carton are taken out, the grabbing suction cup 41 sucks the inner bottom surface of the carton to grab the carton and place it between the third movable plate 51 and the push plate 52, and is fixed by the third negative pressure suction nozzle 55. Then the grabbing suction cup 41 on the synchronous belt truss 4 continues to move downward to poke the four folded edges at the bottom of the carton open and reset; the second telescopic cylinder 56 drives the third movable plate 51 to flip, and after squeezing the carton into a sheet, the second telescopic cylinder 56 drives the third movable plate 51 to reset; the second horizontal drive assembly 53 drives the push plate 52 to move toward the side of the unloading station, and pushes the sheet-like cartons to the unloading station for stacking and storage, which is convenient for the subsequent centralized recycling of empty cartons.
