Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to an automatic paper ream packaging device. Background Art

[0002] Traditional packaging methods for paper reams usually involve multiple processes, including the feeding and cutting of packaging paper, and the processes of wrapping, corner folding, and edge folding the packaging paper around the paper ream, that is, including multiple steps. Traditionally, each step process is processed by a separate machine. This decentralized processing method not only results in a large floor area for the entire production line, but also increases the equipment investment cost and maintenance complexity.

[0003] In order to reduce the space occupied by equipment and improve production efficiency, some improved designs integrate different packaging processes on the same device. For example, Patent CN201921073800.0 discloses an A4 paper double rotary knife paper ream production line, which realizes a compact design by integrating multiple processes. Although such integrated production lines have improved in terms of space utilization compared to traditional decentralized production lines, due to the lack of tight connection between processes, multiple driving devices are still required to support the operation of different processes, and the driving methods include many non-linear drives, which not only increases the energy consumption of the equipment, but also may lead to an increase in maintenance costs due to complex mechanical structures. In addition, although such production lines can achieve high yields, they still need to be optimized in terms of energy consumption and overall operating costs. Summary of the Invention

Detailed implementation manner

[0035] For the convenience of understanding by those skilled in the art, the present utility model will be further described below in conjunction with embodiments and the accompanying drawings. The content mentioned in the implementation manner does not limit the present utility model. The present utility model will be described in detail below with reference to the accompanying drawings.

[0036] An automatic sheet packaging device provided in this embodiment, such as Figures 1 to 9 , includes a frame, and also includes a loading device 37, a packaging paper loading and cutting device 38, a sheet feeding mechanism 1, a paper wrapping mechanism, a corner folding mechanism, a sealing edge mechanism, a gluing mechanism 5, and an unloading device 39 installed on the frame; among them, the loading device 37, the packaging paper loading and cutting device 38, and the unloading device 39 are all prior arts. The loading device 37 is used to transfer the sheets to be packaged to the sheet feeding mechanism 1, and the conveyor belt transmission method can be adopted. The packaging paper loading and cutting device 38 is used to transfer the packaging paper. As shown in the figure, the packaging paper is transferred and cut into a predetermined size and then transferred to the packaging space 4 of the packaging mechanism. Then, packaging can be carried out by Figure 2 way. The unloading device 39 can also adopt common unloading methods such as conveyor belts and conveyor rollers to transfer the packaged sheets away. The specific structure will not be elaborated in this embodiment.

[0037] Among them, the wrapping paper mechanism of this embodiment includes a left folding mechanism and a right folding mechanism. There is a packaging space 4 between the left folding mechanism and the right folding mechanism. The packaging space 4 is provided with wrapping paper 33 for wrapping reams of paper. The ream paper conveying mechanism 1 is used to convey reams of paper to the packaging space 4. The left folding mechanism and the right folding mechanism respectively fold and wrap the wrapping paper 33 around the outer periphery of the reams of paper; the corner folding mechanism includes a movable corner folding component and a fixed corner folding component. The movable corner is located above the left folding mechanism, and the fixed corner folding component is located above the right folding mechanism; the edge sealing mechanism includes a folding edge component. The fixed corner folding component is located between the movable corner folding component and the folding edge component. Specifically, after the wrapping paper 33 is wrapped around the outer periphery of the reams of paper, the movable corner folding component folds the two top corners on one side of the wrapping paper 33, causing the reams of paper to move towards the folding edge component. While the reams of paper are moving, the fixed corner folding component folds the two top corners on the other side of the wrapping paper 33; the gluing mechanism 5 is used to apply glue to the upper side or the lower side of the wrapping paper 33 after corner folding, and the folding edge component is used to fold and bond the upper side and the lower side of the wrapping paper 33.

[0038] As Figure 2 shown, it is the packaging method of reams of paper. The flat wrapping paper 33 is first wrapped around the reams of paper, and then the two ends of the wrapping paper 33 are folded at the corners and the edges, thus completing the packaging production of reams of paper. Furthermore, in order to improve the compactness of the connection between each production process in this embodiment, on the one hand, it can improve production efficiency and reduce the occupied space of the production device, and on the other hand, it can reduce the number of driving devices, which can reduce production costs to a certain extent.

[0039] More specifically, the working process of this embodiment is as follows:

[0040] 1. Wrapping: The ream paper conveying mechanism 1 is a prior art. Driven by the ream paper conveying mechanism 1, the reams of paper rise from below the packaging space 4 and gradually rise to the packaging space 4 between the left folding mechanism and the right folding mechanism. There is flat wrapping paper 33 above the reams of paper. The two ends of the wrapping paper 33 are respectively located below the left folding mechanism and the right folding mechanism. While the reams of paper are rising, the wrapping paper 33 can be lifted from the middle. When the reams of paper move to the packaging space 4, the left folding mechanism and the right folding mechanism act, pushing and folding the wrapping paper 33 along the lower direction of the reams of paper towards the middle, thus wrapping the flat wrapping paper 33 around the reams of paper;

[0041] 2. Corner folding: After the left folding mechanism and the right folding mechanism complete the pushing and folding actions, the movable corner folding component located above the left folding mechanism starts to fold the top corner on the left side of the wrapping paper 33. After completing the corner folding action on the left side, the reams of paper are moved towards Figure 5 the right side, and during the moving process, the fixed corner folding component folds the top corner on the right side of the wrapping paper 33;

[0042] 3. Hemming: After the paper sheet moves to the right to complete the right-angled folding action, the paper sheet continues to move to the right. The hemming assembly includes a lower hemming unit and an upper hemming unit. During the movement of the paper sheet, the gluing mechanism 5 applies glue to the lower side first, then continues to move, and the lower hemming unit folds the lower side of the wrapping paper 33 upward, and then the upper hemming assembly folds the upper side downward so that the upper side fits and adheres to the lower side, thereby completing the wrapping work of the wrapping paper 33. Then, the paper sheet with the completed wrapping is discharged.

[0043] The paper wrapping mechanism provided in this embodiment is as Figure 2 , Figure 4 and Figure 5 shown. Its left paper folding mechanism includes a left paper folding board 8 and a left paper folding driving assembly for driving the movement of the left paper folding board 8. The right paper folding mechanism includes a right paper folding board 9 and a right paper folding driving assembly for driving the movement of the right paper folding board 9. Both the left paper folding board 8 and the right paper folding board 9 can be slidably installed on the frame. Among them, the left paper folding driving assembly includes a left paper folding driver 10, a left driving rod 11 and a left driving arm 12. The left paper folding driver 10 is fixed to the frame. The output end of the left paper folding driver 10 is drivingly connected to one end of the left driving rod 11. One end of the left driving arm 12 is hinged to the left driving rod 11, and the other end of the left driving arm 12 is hinged to the left paper folding board 8. The right paper folding driving assembly includes a right paper folding driver 13, a right driving rod 14 and a right driving arm 15. The right paper folding driver 13 is fixed to the frame. The output end of the right paper folding driver 13 is drivingly connected to one end of the right driving rod 14. The other end of the right driving rod 14 is hinged to one end of the right driving arm 15, and the other end of the right driving arm 15 is hinged to the right paper folding board 9.

[0044] Specifically, as Figure 5 shown, both the left paper folding driver 10 and the right paper folding driver 13 are prior arts. A servo motor can be optionally used for driving. When the paper sheet moves to the packaging space 4, the left paper folding driver 10 drives the left driving rod 11 to rotate. The left driving rod 11 drives the left paper folding board 8 to move towards the center of the packaging space 4 through the left driving arm 12. The left paper folding board 8 can be slidably installed on the frame. The working principle of the right paper folding driving assembly is the same as that of the left paper folding driving assembly. The right paper folding board 9 is driven to move through the right paper folding driver 13. When both the left paper folding board 8 and the right paper folding board 9 move towards the middle, the wrapping paper 33 can be pushed and folded to cover the outer periphery of the paper sheet, forming the state as Figure 2 shown. Among them, both the left paper folding board 8 and the right paper folding board 9 can be provided with vacuum channels and corresponding air holes. The vacuum channels are connected to an external vacuum pumping device. Therefore, when the wrapping paper 33 is laid flat, the wrapping paper 33 can be assisted to be sucked by the air holes, thereby ensuring the stability of the wrapping paper 33 and avoiding inaccurate packaging caused by the movement of the wrapping paper 33.

[0045] Furthermore, the paper wrapping mechanism further includes a packaging fixing assembly located above the packaging space 4, asFigure 2 and Figure 5 As shown in Figure 5 , the packaging fixing component includes a packaging pressing driver 16 and a pressing fixed plate 17. The output end of the packaging pressing driver 16 is drivingly connected to the pressing fixed plate 17 and is used to control the lifting of the pressing fixed plate 17. The pressing fixed plate 17 is located above the wrapping paper 33. Among them, the pressing driver 16 is preferably driven by a cylinder.

[0046] Specifically, as Figure 2 shown, the pressing fixed plate 17 is located above the wrapping paper 33. By installing brackets at the corresponding positions on the frame, the pressing driver 16 is fixed to the brackets. While the paper rises to the packaging space 4, the pressing driver 16 drives the pressing fixed plate 17 to descend, so that the pressing fixed plate 17 is located above the wrapping paper 33. When the paper continues to rise and pushes the wrapping paper 33 upward, the pressing fixed plate 17 contacts the wrapping paper 33 and rises with the wrapping paper 33, so that the wrapping paper 33 can be kept in a state of being attached to the paper, ensuring the packaging accuracy of the wrapping paper 33 and reducing the occurrence of mistakes.

[0047] The corner folding mechanism of this embodiment is as Figures 4 to 8 shown. Among them, the movable corner folding component includes a corner folding driver 18, a corner folding driving plate 19 and a movable corner folding piece 20. The corner folding driver 18 is fixed to the left folding paper board 8. The output end of the corner folding driver 18 is drivingly connected to the corner folding driving plate 19. Movable corner folding pieces 20 are installed at both ends of the corner folding driving plate 19. The two movable corner folding pieces 20 are respectively located at both ends of the paper and are used to fold the two top corners on one side of the wrapping paper 33; the fixed corner folding component includes fixed corner folding pieces 21 located on both sides of the paper. The fixed corner folding pieces 21 are fixed to the frame. The right folding paper board 9 is located below the fixed corner folding pieces 21; a passage for the lower side edge of the wrapping paper 33 to be sealed is formed between the fixed corner folding pieces 21 and the right folding paper board 9. The gluing mechanism 5 is located below the passage and is used to glue the lower side edge of the wrapping paper 33. Among them, the shapes of the movable corner folding piece 20 and the fixed corner folding piece 21 are both L-shaped.

[0048] Specifically, as Figure 5 shown, the movable corner folding piece 20 is preferably arranged on the left folding paper board 8. The position of the movable corner folding piece 20 when not operating has a sufficient distance from the edge of the left folding paper board 8 to avoid affecting the paper folding action of the left folding paper board 8. After the left folding paper board 8 completes the pushing and folding action of the wrapping paper 33, as Figure 7At the position shown, at this time, the folding angle driver 18 pushes the two movable folding angle members 20 to move leftward through the folding angle driving plate 19, so that the movable folding angle members 20 fold the top corner on the left side of the wrapping paper 33 to complete the folding angle action. The folding angle driver 18 drives the movable folding angle members 20 to reset, and at the same time, the left folding cardboard 8 starts to reset. Then, it is necessary to control the command paper to move to the right. Since the command paper is located on the right folding cardboard 9 at this time, driving the right folding cardboard 9 to reset can drive the command paper to move to the right. At the same time, cooperating with the paper pushing mechanism to ensure that the command paper can be pushed to move to the right. When the command paper passes through the two fixed folding angle members 21, because the distance between the two fixed folding angle members 21 is the same as or slightly larger than the width of the command paper, when the command paper enters between the two fixed folding angle members 21, the top corner on the right side can be folded. In addition, there is a passage between the fixed folding angle member 21 and the right folding cardboard 9, as Figure 6 shown, that is, the fixed folding angle member 21 does not contact the right folding cardboard 9, ensuring that the lower side of the wrapping paper 33 can move into the passage when the command paper moves.

[0049] The hemming assembly of this embodiment is as Figure 5 , Figure 6 and Figure 8 shown, including a lower hemming unit and an upper hemming unit. The lower hemming unit includes lower hemming plates 24 located on both sides of the command paper. The lower hemming plates 24 are fixed to the frame. The lower hemming plates 24 and the fixed folding angle members 21 are in the same plane. The bottom of the lower hemming plates 24 is lower than the bottom of the fixed folding angle members 21. A hemming channel 25 is provided between the lower hemming plates 24 and the fixed folding angle members 21. The hemming channel 25 is inclined and the hemming channel 25 is used to fold the lower side of the wrapping paper 33 upward; upper hemming assemblies are provided at both ends of the command paper. The upper hemming assembly includes an upper hemming driver 26 and an upper hemming plate 27. The upper hemming plate 27 is located above the upper side of the wrapping paper 33. The upper hemming driver 26 is used to drive the upper hemming plate 27 to descend to fold the upper side so that the upper side fits with the lower side.

[0050] Specifically, as Figure 5, the frame is provided with a moving channel for the paper sheet. When the right folding cardboard 9 is not actuated, it is connected to the moving channel to ensure that the paper sheet can be accurately conveyed from the right folding cardboard 9 to the moving channel. The two lower folding edge plates 24 of the lower folding edge unit are located on both sides of the moving channel and are connected to the fixed folding angle member 21, that is, the distance between the two lower folding edge plates 24 is the same as the distance between the two fixed folding angle members 21. During actual operation, the gluing mechanism 5 can be arranged at the channel opening of the folding edge channel 25. When the lower side enters the folding edge channel 25, an appropriate amount of glue will be sprayed on the surface of the lower side by the gluing mechanism 5 first. Since the bottom of the lower folding edge plate 24 is lower than that of the fixed folding angle member 21, and preferably the bottom of the lower folding edge plate 24 is in contact with the moving channel, when the lower side of the wrapping paper 33 moves to the folding edge channel 25, it will enter the folding edge channel 25 and move due to the blockage of the lower folding edge plate 24. The folding edge channel 25 is inclined, such as Figure 6 shown in the direction from the lower left to the upper right, so that the lower side can be folded upward along the folding edge channel 25. The paper sheet continues to move to the right. When it moves below the upper folding edge unit, the paper sheet stops moving. At this time, the upper folding edge driver 26 drives the upper folding edge plate 27 to move downward, and the upper folding edge plate 27 pushes the upper side downward to fold. Since the outer side of the lower side is coated with glue, the upper side can be pasted to the lower side through the glue after folding. Further, to ensure that the upper side and the lower side can fit better, a pressing component is also provided in this embodiment, such as Figure 8 shown. The upper folding edge plate 27 folds the upper side, and at the same time, the pressing driver 28 controls the pressing plate 29 to move to fit the paper sheet, that is, presses the upper side against the lower side, so that the glue fully adheres the upper side and the lower side tightly, ensuring the integrity and stability of the packaging.

[0051] In this embodiment, the paper sheet is driven to move by a paper pushing mechanism, such as Figure 5 shown. The paper pushing mechanism includes a push plate 30, a push plate lifting driver 31, and a push plate moving drive assembly 32. The push plate 30 is located above the paper sheet. The push plate lifting driver 31 is used to control the lifting of the push plate 30, and the push plate moving drive assembly 32 is used to drive the push plate 30 to translate to push the paper sheet to move.

[0052] Specifically, the push plate 30 can be lifted and translated. When no operation is required, the push plate 30 is located above the paper sheet. When it is necessary to control the movement of the paper sheet, the push plate lifting driver 31 controls the push plate 30 to descend, and then the push plate moving drive assembly 32 controls the push plate lifting driver 31 and the push plate 30 to translate. Among them, the structure of the push plate moving drive assembly 32 is as Figure 5 shown. Optionally, the movement of the push plate 30 can be controlled by the structure of a servo motor and a synchronous belt. This is prior art and will not be elaborated here.

[0053] In this embodiment, in the movable folding component and the fixed folding component of the folding mechanism, only the driving structure needs to be arranged on the movable folding component. In the upper folding component and the lower folding component of the edge folding mechanism, only the driving structure needs to be arranged on the upper folding component. In the paper wrapping mechanism, although driving structures are arranged on both the left paper folding mechanism and the right paper folding mechanism, the driving structure of the left paper folding mechanism is also used to drive the movable folding component to move, and the driving structure of the right paper folding mechanism is also used to drive the paper sheet to move. Therefore, while the structure of this embodiment is compact, the number of driving structures used is also small, and most of the driving structures adopt the linear driving method, that is, a cylinder can be used for driving. Therefore, the energy consumption during the production of this embodiment can be reduced, and high-efficiency operation can also be achieved. For example, the folding and edge folding operations can be completed during the movement of the paper sheet, so the operation time can be shortened, and the practicability is high.

[0054] As mentioned above, the above is only a preferred embodiment of the present invention, and it does not impose any form of limitation on the present invention. Although the present invention is disclosed above in a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art, without departing from the scope of the technical solution of the present invention, when making some changes or modifications using the above-disclosed technical content as equivalent change equivalent embodiments, but as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical meaning of the present invention shall fall within the scope of the technical solution of the present invention.
