[0021] In one embodiment, such as Figures 1-4As shown, a wet wipe packaging machine includes a feeding conveyor belt component 11 and a sliding support plate 24. The feeding conveyor belt component 11 is installed on the upper end of a first processing counter 12. A receiving platform 33 is fixedly provided on the upper end of the first processing counter 12 at one end of the feeding conveyor belt component 11. The sliding support plate 24 is slidably disposed inside a fixed frame. The fixed frame is fixedly disposed on the upper end of a second processing counter 31. The sliding support plate 24 is fixedly connected to the output end of a second cylinder 25, which is fixedly disposed on the fixed frame. A pusher 17 is provided on one side of the feeding conveyor belt component 11. The pusher 17 is fixedly disposed on one end of a fixed rod 18. A drive assembly for moving the fixed rod 18 is provided on the upper end of the first processing counter 12. The upper end of the 2 is provided with a pushing mechanism for pushing the material on the upper end of the receiving platform 33 to one end of the pusher head 17. The upper end of the fixed frame is provided with a storage bag box 22. The upper end of the second processing table 31 is provided with a tensioning mechanism for opening the packaging bag at one side of the sliding bearing plate 24. The upper end of the second processing table 31 is provided with a rear sealing component 27 at the other side of the sliding bearing plate 24. The rear sealing component 27 is provided with a discharge conveyor belt component 30 on one side. The pushing mechanism facilitates the material conveyed by the feeding conveyor belt component 11 to be pushed to one end of the pusher head 17 and sorted, so that the pusher head 17 can push the stacked material to the upper end of the sliding bearing plate 24. The tensioning mechanism facilitates the opening of one end of the packaging bag, making it easier to place the stacked wet wipes inside the packaging bag.
[0022] The drive assembly includes a sliding frame 19, with a fixed rod 18 fixedly mounted on one side of the sliding frame 19. A first guide rod is slidably mounted on the sliding frame 19, and the first guide rod is fixedly mounted on the upper end of the first processing counter 12. The sliding frame 19 is fixedly mounted on a transmission belt 20, with a drive wheel and a transmission wheel respectively fitted at both ends of the transmission belt 20. Both the drive wheel and the transmission wheel are rotatably mounted on the upper end of the first processing counter 12. The rotating shaft on one side of the drive wheel is fixedly connected to the output end of a motor 21, which is fixedly mounted on the upper end of the first processing counter 12. In use, when the push head 17 needs to move, the motor 21 is started, and the output end of the motor 21 drives the drive wheel to rotate. The drive wheel and the transmission wheel cooperate to make the transmission belt 20 rotate, and the transmission belt 20 drives the sliding frame 19 to slide along the length direction of the first guide rod. The sliding frame 19 drives the push head 17 to move through the fixed rod 18.
[0023] The pushing mechanism includes a pushing frame 14, which is closely attached to the upper end of the receiving platform 33. The pushing frame 14 is fixed on the output end of the first cylinder 15, which is fixed on the upper end of the first processing counter 12. A sorting rack 16 is provided above the first processing counter 12 at one end of the pushing frame 14. The sorting rack 16 is fixed on the output end of the fourth cylinder, which is fixed on the second mounting frame. The second mounting frame is fixed on the upper end of the first processing counter 12. The pushing frame 14 and the sorting rack 16 are respectively located on both sides of the pushing head 17. In use, when it is necessary to pack wet wipes into intermediate packages, multiple wet wipes are stacked on the upper end of the feeding conveyor belt component 11. The feeding conveyor 11 conveys the wet wipes. After the wet wipes move to one end of the feeding conveyor 11, they are conveyed to the upper end of the receiving platform 33. Then, the first cylinder 15 is activated. The output end of the first cylinder 15 pushes the wet wipes to move through the pusher 14. At the same time, the fourth cylinder is activated, causing the fourth cylinder to drive the sorting rack 16 to move. When one side of the wet wipe is in close contact with one side of the sorting rack 16, the output end of the first cylinder 15 drives the pusher 14 to move to the initial position. At the same time, the pusher 17 pushes the wet wipes below the sorting rack 16 to move a certain distance. Then, the feeding conveyor 11 conveys the same number of wet wipes again. The pusher 14 repeats the operation. After two conveyings, the wet wipes are conveyed to the bottom of the sorting rack 16, so that the wet wipes that need to be packaged are neatly arranged.
[0024] The tensioning mechanism includes a tensioning frame 23 and an offset push plate 26. The two tensioning frames 23 are symmetrically arranged. A fixed rod is fixedly mounted on one side of each tensioning frame 23. A sliding block is rotatably mounted at one end of each fixed rod. A second guide rod is slidably mounted at the bottom end of each sliding block. The second guide rods are fixedly mounted on the upper end of the second processing table 31. The two sliding blocks are respectively fixedly connected to the output ends of two fifth cylinders. The fifth cylinders are fixedly mounted on the upper end of the second processing table 31. A fixed block is fixedly mounted on each fixed rod. A connecting rod is hinged to the upper end of each fixed block. A rotating column is hinged to the other end of each connecting rod. The rotating columns are fixedly mounted on the upper end of the second processing table 31. The upper end of the sliding bearing plate 24 is connected to the storage bag. Several suction cup holes are provided at the corresponding positions of the box 22, and each suction cup hole is equipped with a suction cup. The upper end of the sliding support plate 24 is closely attached to the offset push plate 26, which is fixedly mounted on the output end of the sixth cylinder. The sixth cylinder is fixedly mounted on the upper end of the second processing table 31. In use, when it is necessary to package the wet wipes, the output end of the fifth cylinder drives the sliding block to move. Under the action of the connecting rod, the fixed rod drives the tension frame 23 to rotate, so that one end of the two tension frames 23 moves closer to each other, and the distance between the tension frames 23 and the side of the tension frame 23 closest to the sliding support plate 24 decreases. Then, the output end of the second cylinder 25 drives the sliding support plate 24 to slide, so that the sliding support plate 24 drives several suction cups to move. At the same time, the suction cups are connected to the first cylinder 24 through the hose. The vacuum component input end of the second processing cabinet 31 is connected. When the suction cup is in close contact with the packaging bag inside the storage bag box 22, the vacuum component fixes the packaging bag through the suction cup. Then, the output end of the second cylinder 25 drives the sliding support plate 24 to move, which pulls the packaging bag inside the storage bag box 22 and opens the packaging bag. The vacuum component then exhausts air, causing the suction cup to stop fixing the packaging bag. The sixth cylinder drives the offset push plate 26 to move, which pushes the packaging bag to one end of the two tensioning frames 23. Then, the fifth cylinder drives the sliding block to move to the initial position, so that one end of the tensioning frame 23 is inserted into the opening of the packaging bag, thus supporting the opening end of the packaging bag. Then, the transmission belt 20 rotates, driving the push head 17 to move. 7. Push the stacked tissues to move, so that the wet wipes pass through the middle of the two support frames 23 and then move into the inside of the packaging bag. Then, the fifth cylinder drives the sliding block to move again, so that the support frames 23 release the packaging bag from the fixation. The pusher 17 continues to push the wet wipes and packaging bag to the bottom of the rear sealing component 27, so that the opening of the packaging bag moves to the processing position of the rear sealing component 27. At the same time, one end of the pusher 17 is separated from the inside of the packaging bag. Then, the rear sealing component 27 seals the opening of the packaging bag. It is worth noting that the feeding conveyor belt component 11, the rear sealing component 27, the vacuuming component and the discharging conveyor belt component 30 in this application all use existing components and the technology is relatively mature, so they will not be described in detail here. Then, the pusher 17 pushes the middle pack of wet wipes to move again.
[0025] A positioning plate 28 is provided above the second processing cabinet 31. The positioning plate 28 is located above the discharge conveyor belt component 30. The positioning plate 28 is fixed on the output end of the third cylinder 29. The third cylinder 29 is fixed on the third mounting frame. The third mounting frame is fixed on the upper end of the second processing cabinet 31. In use, when the pusher 17 pushes the wet wipes to move below the rear sealing component 27 for sealing processing, the output end of the third cylinder 29 drives the positioning plate 28 to move. When the wet wipe package to be processed contacts one side of the positioning plate 28, the pusher 17 stops pushing the wet wipe package to move. After the rear sealing component 27 seals the packaging bag, the third cylinder 29 drives the positioning plate 28 back to the initial position. At the same time, the pusher 17 pushes the wet wipe package to move to the upper end of the discharge conveyor belt component 30. Then the discharge conveyor belt component 30 transports the wet wipe package.
[0026] The first processing counter 12 is provided with a support frame at the upper end, and a human-machine interface 32 is provided at one end of the support frame. When in use, the human-machine interface 32 is electrically connected to multiple electrical components in the device, so as to control them. The human-machine interface 32 uses existing components.
[0027] The above embodiment discloses a wet wipes packing machine. When packing wet wipes, multiple wet wipes are stacked on the upper end of the feeding conveyor belt component 11. The feeding conveyor belt component 11 conveys the wet wipes. After the wet wipes move to one end of the feeding conveyor belt component 11, they are conveyed to the upper end of the receiving platform 33. Then, the first cylinder 15 is activated. The output end of the first cylinder 15 pushes the wet wipes through the pusher frame 14. Simultaneously, the fourth cylinder is activated, causing the fourth cylinder to drive the sorting frame 16 to move. When one side of the wet wipes is in close contact with one side of the sorting frame 16, the output end of the first cylinder 15 drives the pusher frame 14 to move to the initial position. At the same time, the pusher head 17 pushes the wet wipes below the sorting frame 16 a certain distance. Then, the feeding conveyor belt component 11 conveys the same number of wet wipes again. The wet wipes are repeatedly conveyed by the pusher 14. After two conveying operations, the wet wipes are conveyed to the bottom of the sorting rack 16. The output end of the fifth cylinder drives the sliding block to move. Under the action of the connecting rod, the fixed rod drives the tension frame 23 to rotate, so that one end of the two tension frames 23 moves closer to each other, and the distance between the tension frames 23 and the side of the sliding support plate 24 decreases. Then, the output end of the second cylinder 25 drives the sliding support plate 24 to slide, so that the sliding support plate 24 drives several suction cups to move. At the same time, the suction cups are connected to the input end of the vacuum component inside the second processing cabinet 31 through the hose. When the suction cups are in close contact with the packaging bags inside the storage bag box 22, the vacuum component fixes the packaging bags through the suction cups. Then, the output end of the second cylinder 25 drives the sliding support plate 24 to move, so that the storage bag box 22 is pulled. 2. The inner packaging bag moves, simultaneously opening the bag. The vacuum component releases air, causing the suction cup to stop fixing the bag. The sixth cylinder drives the offset push plate 26 to move, pushing the bag to one end of the two support frames 23. Then, the fifth cylinder drives the sliding block to its initial position, inserting one end of the support frame 23 into the opening of the bag, thus supporting the opening. The motor 21 is started, and its output drives the drive wheel to rotate. The drive wheel and transmission wheel work together to rotate the transmission belt 20. The transmission belt 20 drives the sliding frame 19 to slide along the length of the first guide rail. The sliding frame 19 drives the push head 17 to move via the fixed rod 18. The push head 17 pushes the stacked tissues, causing the wet wipes to pass through the two supports. The tensioner 23 moves to the middle and then into the packaging bag. Then, the fifth cylinder drives the sliding block to move again, causing the tensioner 23 to release the packaging bag from its fixation. At the same time, the output end of the third cylinder 29 drives the positioning plate 28 to move. When the wet wipe package to be processed contacts one side of the positioning plate 28, the pusher 17 stops pushing the wet wipe package. After the opening of the packaging bag moves to the processing position of the rear sealing component 27, one end of the pusher 17 disengages from the packaging bag. Then, the rear sealing component 27 seals the opening of the packaging bag. After the rear sealing component 27 seals the packaging bag, the third cylinder 29 drives the positioning plate 28 back to the initial position. At the same time, the pusher 17 pushes the wet wipe package to the upper end of the discharge conveyor belt component 30. Then, the discharge conveyor belt component 30 transports the wet wipe package.
