Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to a low - energy - consumption packaging device. Background Art

[0002] Daily - used papers, such as A4 papers, etc., need to be precisely packaged after production. Usually, a certain number of papers are bundled into a stack, called a "ream of paper". The packaging process of a ream of paper mainly includes cutting a special packaging paper into a suitable size, then covering it on the outside of the ream of paper, and completing necessary corner - folding and edge - folding operations to ensure that the packaging paper can completely and firmly wrap the ream of paper.

[0003] Traditional packaging methods usually involve multiple independent processes, and each process requires a dedicated machine to execute, such as cutting, covering, corner - folding, and edge - folding, etc. 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.

[0004] 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, the Chinese utility model patent CN201921073800.0 discloses a double - rotary - knife paper - cutting ream - of - paper production line for A4 papers. This production line realizes a compact design by integrating multiple processes. Although such an integrated production line has improvements in 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 operations of different processes. This not only increases the energy consumption of the equipment, but also may lead to an increase in maintenance costs due to the complex mechanical structure. In addition, although this production line can achieve a high output, there is still room for optimization in terms of energy consumption and overall operating costs. Summary of the Invention

Detailed implementation mode

[0032] For the convenience of understanding by those skilled in the art, the following further describes the present utility model in conjunction with embodiments and the accompanying drawings. The content mentioned in the implementation mode does not limit the present utility model. The following describes the present utility model in detail with reference to the accompanying drawings.

[0033] A low - energy - consumption packaging device provided in this embodiment is as Figures 1 to 8 , including a frame, and further including a sheet conveying mechanism 1, a paper wrapping mechanism, a corner folding mechanism, a hemming mechanism, and a gluing mechanism 5 installed on the frame;

[0034] Among them, the paper wrapping mechanism includes a left paper folding mechanism and a right paper folding mechanism. A packaging space 4 is arranged between the left paper folding mechanism and the right paper folding mechanism. The packaging space 4 is provided with a packaging paper 33 for packaging the sheet. The sheet conveying mechanism 1 is used to convey the sheet to the packaging space 4, and the left paper folding mechanism and the right paper folding mechanism are respectively used to fold and wrap the packaging paper 33 around the outer periphery of the sheet; the corner folding mechanism includes a movable corner folding assembly and a fixed corner folding assembly. The movable corner folding is located above the left paper folding mechanism, and the fixed corner folding assembly is located above the right paper folding mechanism; the hemming mechanism includes a hemming assembly. The fixed corner folding assembly is located between the movable corner folding assembly and the hemming assembly. Specifically, after the packaging paper 33 is wrapped around the outer periphery of the sheet, the movable corner folding assembly folds the two top corners on one side of the packaging paper 33, causing the sheet to move towards the hemming assembly. While the sheet is moving, the fixed corner folding assembly folds the two top corners on the other side of the packaging paper 33; the gluing mechanism 5 is used to apply glue to the upper side edge or the lower side edge of the packaging paper 33 after corner folding, and the hemming assembly is used to fold and bond the upper side edge and the lower side edge of the packaging paper 33.

[0035] As Figure 2As shown in the figure, it is the packaging method of the ream paper. First, the flat packaging paper 33 is wrapped around the ream paper, and then the two ends of the packaging paper 33 are folded at the corners and edges, thus completing the packaging production of the ream 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. On the other hand, it can reduce the number of driving devices and can reduce production costs to a certain extent.

[0036] More specifically, the working process of this embodiment is as follows:

[0037] 1. Wrapping: The ream paper conveying mechanism 1 is a prior art. Driven by the ream paper conveying mechanism 1, the ream paper rises from the lower part of the packaging space 4 and gradually rises to the packaging space 4 between the left folding mechanism and the right folding mechanism. The packaging paper 33 is laid flat above the ream paper, and the two ends of the packaging paper 33 are respectively located below the left folding mechanism and the right folding mechanism. While the ream paper is rising, the packaging paper 33 can be lifted from the middle of the packaging paper 33. When the ream paper moves to the packaging space 4, the left folding mechanism and the right folding mechanism act to push and fold the packaging paper 33 along the lower side of the ream paper towards the middle, thereby wrapping the flat packaging paper 33 around the ream paper;

[0038] 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 packaging paper 33. After completing the corner folding action on the left side, the ream paper is moved Figure 4 to the right, and during the moving process, the fixed corner folding component folds the top corner on the right side of the packaging paper 33;

[0039] 3. Edge folding: After the ream paper moves to the right to complete the corner folding action on the right side, the ream paper continues to move to the right. The edge folding component includes a lower edge folding unit and an upper edge folding unit. During the movement of the ream paper, first, the gluing mechanism 5 applies glue to the lower side, then continues to move and the lower edge folding unit folds the lower side of the packaging paper 33 upwards, and then the upper edge folding component folds the upper side downwards so that the upper side fits and adheres to the lower side, thereby completing the wrapping work of the packaging paper 33, and the wrapped ream paper can be discharged.

[0040] The paper wrapping mechanism provided in this embodiment is as Figure 2 、 Figure 3 and Figure 4As shown, its left paper folding mechanism includes a left paper folding board 8 and a left paper folding driving component 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 component 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 component 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 component 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.

[0041] Specifically, as Figure 4 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 is moved 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 component is the same as that of the left paper folding driving component. 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 packaging paper 33 can be pushed and folded to cover the outer periphery of the paper to be packaged, forming Figure 2 the state 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 communicated with an external vacuum pumping device. Therefore, when the packaging paper 33 is laid flat, the packaging paper 33 can be assisted to be sucked through the air holes, so as to ensure the stability of the packaging paper 33 and avoid inaccurate packaging caused by the movement of the packaging paper 33.

[0042] Furthermore, the paper wrapping mechanism further includes a packaging fixing component located above the packaging space 4. As Figure 2 and Figure 4 shown, 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 packaging paper 33. Among them, the pressing driver 16 preferably uses a cylinder for driving.

[0043] Specifically, as Figure 2, the lower pressing fixing plate 17 is located above the wrapping paper 33. By installing brackets at the corresponding positions on the frame, the lower pressing driver 16 is fixed to the brackets. While making the paper rise to the packaging space 4, the lower pressing driver 16 drives the lower pressing fixing plate 17 to descend, so that the lower pressing fixing plate 17 is located above the wrapping paper 33. When the paper continues to rise and pushes the wrapping paper 33 upward, the lower pressing fixing plate 17 contacts the wrapping paper 33 and rises with the wrapping paper 33, enabling the wrapping paper 33 to keep in a state of fitting with the paper, ensuring the packaging accuracy of the wrapping paper 33 and reducing the occurrence of mistakes.

[0044] The corner folding mechanism of this embodiment is as Figures 3 to 7 shown, in which the movable corner folding assembly includes a corner folding driver 18, a corner folding driving plate 19 and movable corner folding members 20. The corner folding driver 18 is fixed to the left folding cardboard 8, the output end of the corner folding driver 18 is drivingly connected to the corner folding driving plate 19, and movable corner folding members 20 are installed at both ends of the corner folding driving plate 19. The two movable corner folding members 20 are respectively located at both ends of the paper, and are used for folding the two top corners on one side of the wrapping paper 33; the fixed corner folding assembly includes fixed corner folding members 21 located on both sides of the paper, the fixed corner folding members 21 are fixed to the frame, and the right folding cardboard 9 is located below the fixed corner folding members 21; a passage for the lower side edge of the wrapping paper 33 to be sealed passes between the fixed corner folding members 21 and the right folding cardboard 9, and the gluing mechanism 5 is located below the passage and is used for gluing the lower side edge of the wrapping paper 33. Among them, the shapes of the movable corner folding members 20 and the fixed corner folding members 21 are both L-shaped.

[0045] Specifically, as Figure 4 shown, the movable corner folding member 20 is preferably arranged on the left folding cardboard 8, and there is a sufficient distance between the position of the movable corner folding member 20 when it is not actuated and the edge of the left folding cardboard 8 to avoid affecting the paper folding action of the left folding cardboard 8. When the left folding cardboard 8 completes the pushing and folding action of the wrapping paper 33, as Figure 6 shown in the position, at this time the corner folding driver 18 pushes the two movable corner folding members 20 to move leftward through the corner folding driving plate 19, so that the movable corner folding member 20 folds the top corner on the left side of the wrapping paper 33 to complete the corner folding action, and the corner folding driver 18 drives the movable corner folding member 20 to reset, and at the same time the left folding cardboard 8 starts to reset. Then it is necessary to control the paper to move rightward. Since the paper is located on the right folding cardboard 9 at this time, controlling the reset of the right folding cardboard 9 can drive the paper to move rightward at the same time, and cooperate with the paper pushing mechanism to ensure that the paper can be pushed to move rightward. When the paper passes between the two fixed corner folding members 21, because the distance between the two fixed corner folding members 21 is the same as or slightly larger than the width of the paper, when the paper enters between the two fixed corner folding members 21, the top corner on the right side can be folded. In addition, a passage is provided between the fixed corner folding member 21 and the right folding cardboard 9, as Figure 5As 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 aisle when the paper moves.

[0046] The hemming assembly of this embodiment is as Figure 4 , Figure 5 and Figure 7 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 paper. The lower hemming plates 24 are fixed to the frame. The lower hemming plates 24 and the fixed folding angle member 21 are in the same plane. The bottom of the lower hemming plates 24 is lower than the bottom of the fixed folding angle member 21. A hemming channel 25 is provided between the lower hemming plates 24 and the fixed folding angle member 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 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.

[0047] Specifically, as Figure 4 shown, the frame is provided with a moving channel for the paper. When the right folding cardboard 9 is not operating, it is connected to the moving channel, ensuring that the paper can be accurately conveyed from the right folding cardboard 9 to the moving channel. The two lower hemming plates 24 of the lower hemming 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 hemming 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 set at the channel opening of the hemming channel 25. Then, when the lower side enters the hemming 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 hemming plate 24 is lower than the fixed folding angle member 21 and preferably the bottom of the lower hemming plate 24 contacts the moving channel, when the lower side of the wrapping paper 33 moves to the hemming channel 25, it will enter the hemming channel 25 and move due to the blockage of the lower hemming plate 24. And the hemming channel 25 is inclined, as Figure 5 shown, inclined from the lower left to the upper right direction. Therefore, the lower side can be folded upward along the hemming channel 25. The paper continues to move to the right. When it moves below the upper hemming unit, the paper stops moving. At this time, the upper hemming driver 26 drives the upper hemming plate 27 to move downward. The upper hemming plate 27 pushes and folds the upper side downward. 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, this embodiment is also provided with a pressing assembly, as Figure 7 shown, the upper hemming plate 27 folds the upper side, and at the same time the pressing driver 28 controls the pressing plate 29 to move to fit with the paper, 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 package.

[0048] In this embodiment, the movement of the paper is driven by a paper pushing mechanism. As Figure 4 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. 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 to move.

[0049] Specifically, the push plate 30 can be lifted and translated. When no operation is required, the push plate 30 is located above the paper. When it is necessary to control the movement of the paper, 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 4 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 the prior art and will not be elaborated here.

[0050] In this embodiment, among the movable folding angle assembly and the fixed folding angle assembly of the folding angle mechanism, only a driving structure needs to be set in the movable folding angle assembly. Among the upper folding edge assembly and the lower folding edge assembly of the folding edge mechanism, only a driving structure needs to be set in the upper folding edge assembly. In the paper wrapping mechanism, although driving structures are set in 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 angle assembly to move, and the driving structure of the right paper folding mechanism is also used to drive the paper 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 a 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 be achieved. For example, the folding angle and folding edge operations can be completed during the movement of the paper, so the operation time can be shortened and the practicability is high.

[0051] The above is only a preferred embodiment of the present invention, and it is not intended to limit the present invention in any form. Although the present invention is disclosed above with 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 to the above-disclosed technical content to obtain an equivalent embodiment of equivalent changes, 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 embodiment according to the technical idea of the present invention shall fall within the scope of the technical solution of the present invention.
