Description

Technical Field

[0001] This utility model relates to the field of food packaging technology, and in particular to a wear-resistant structure for food packaging paper. Background Technology

[0002] With the continuous advancement of technology, people's requirements for packaging materials are also getting higher and higher. Practical packaging materials alone can no longer satisfy consumers. They expect and pursue products with unique features. At present, traditional packaging paper is easily damaged by friction or impact during transportation.

[0003] In the prior art, although Chinese invention publications such as CN113897815A (a method and equipment for improving the bursting strength of food packaging paper) and CN103600916A (a wear-resistant and waterproof packaging paper) have disclosed solutions to the wear resistance problem of food packaging paper, they are basically improvements made to the material of the packaging paper and lack a specific structural design to improve the wear resistance of the packaging paper. Utility Model Content

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A wear-resistant structure for food packaging paper includes a paper shell, one end of which is fixedly connected to a card plate, and the other end of which has a card slot. Multiple cushioning structures are uniformly fixedly connected to the outer surface of the paper shell. A paper-inserting layer is provided inside the paper shell. Multiple honeycomb holes are uniformly opened in the paper-inserting layer. The hollow structure of the paper-inserting layer is a triangular hollow plate inserted between the honeycomb holes. A support layer is glued to one side of the paper-inserting layer. Multiple friction blocks are uniformly installed on the surface of the cushioning structure.

[0006] Preferably, the buffer structure includes an upper shell fixedly connected to the outer surface of the paper shell, a lower shell slidably engaged inside the upper shell, a plurality of first telescopic columns fixedly installed around the upper and lower shells, and a buffer assembly installed at the middle position of the lower shell.

[0007] Preferably, the buffer assembly includes a second telescopic column fixedly installed on the lower end shell. A top plate is fixedly connected to one end of the second telescopic column near the upper end shell. Rotating columns are fixedly installed on both sides of the top plate. A connecting frame is rotatably sleeved on the rotating column. A sliding column is rotatably connected to one end of the connecting frame away from the rotating column. Sliding grooves are provided on both sides of the second telescopic column in the inner wall of the lower end shell. Limiting grooves are provided on both sides of the sliding grooves. The sliding column is slidably connected to the limiting grooves.

[0008] Preferably, a spring is fitted on the outer side of the second telescopic column.

[0009] Preferably, the friction block is fixedly installed on the surface of the lower end shell away from the upper end shell.

[0010] Compared with the prior art, the advantages of this utility model are:

[0011] 1. In this application, by setting up paper interlayer and honeycomb holes, the hollow triangular honeycomb structure itself has good compressive strength characteristics. Its hexagonal honeycomb shape can evenly distribute the pressure to the entire structure. At the same time, the addition of the triangular plate slot structure, especially after the edges of the triangular plates are connected or cooperate with the edges of the honeycomb structure, can provide additional support and reinforcement for the honeycomb structure, further enhancing the overall compressive strength. The lower support layer structure can make the external support effect better.

[0012] 2. In this application, by setting up a buffer structure, when the lower end shell is impacted, the upper end shell will drive the first telescopic column and the second telescopic column to retract. At this time, the spring will also be under force, thereby achieving a certain degree of buffering of the impact force. At the same time, when the connecting frame opens, it will drive the sliding column to slide in the sliding groove, thereby further achieving the buffering of the impact force.

[0013] 3. In this application, friction blocks are provided on the outer surface of the lower shell to increase friction, so that the cardboard box will not slide too much, thus protecting the box body from excessive wear and making it more wear-resistant.

[0014] In summary, the design of the above-mentioned structure can effectively improve the cushioning effect of the cardboard box and enhance its wear resistance. Furthermore, the combination of these two aspects can further reduce the wear resistance of the cardboard box and prevent excessive wear caused by shaking or displacement.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1 to 5 A wear-resistant structure for food packaging paper includes a paper shell 1. One end of the paper shell 1 is fixedly connected to a card plate 17, and the other end is provided with a card slot 18. The width of the card plate 17 is the same as the internal width of the card slot 18, so that the card plate 17 can be embedded in the card slot 18. Multiple buffer structures are uniformly fixedly connected to the outer surface of the paper shell 1. A paper clamping layer 2 is provided inside the paper shell 1. Multiple honeycomb holes 3 are uniformly provided in the paper clamping layer 2. The hollow structure of the paper clamping layer 2 is a triangular hollow plate, which is inserted between the multiple honeycomb holes 3. A support layer 4 is glued to one side of the paper clamping layer 2, which can improve the external support effect. A relatively hard paper material is provided on the outer surface of the paper shell 1.

[0023] The buffer structure is fixedly connected to the upper shell 5 on the outer surface of the cardboard shell 1. The lower shell 6 is slidably engaged inside the upper shell 5. Multiple sets of first telescopic columns 8 are fixedly installed around the upper shell 5 and the lower shell 6. A second telescopic column 16 is fixedly installed in the middle of the lower shell 6. A spring 15 is sleeved on the outside of the second telescopic column 16. A top plate 14 is fixedly connected to the end of the second telescopic column 16 near the upper shell 5. Rotating columns 13 are fixedly installed on both sides of the top plate 14. A connecting frame 12 is rotatably sleeved on the rotating column 13. A sliding column 11 is rotatably connected to the end of the connecting frame 12 away from the rotating column 13. Sliding grooves 9 are provided on both sides of the second telescopic column 16 in the inner wall of the lower shell 6. Limiting grooves 10 are provided on both sides of the sliding grooves 9. The sliding column 11 is slidably connected to the limiting grooves 10.

[0024] Multiple friction blocks 7 are evenly installed on the side of the lower shell 6 away from the upper shell 5, so that the cardboard box will not slide too much.

[0025] The specific working principle of this utility model is as follows: First, the food packaging paper is spliced ​​together, and a card plate 17 is fixedly connected to one end of the cardboard shell 1 at the top. After the splicing is completed, the food is put into it, and then the protruding part of the card plate 17 is folded in half and inserted into the card slot 18 to seal it.

[0026] During transportation, when the cardboard box is subjected to wear and pressure, the lower shell 6 will be squeezed because it is engaged with the upper shell 5. The lower shell 6 and the upper shell 5 are connected by the first telescopic column 8. Therefore, when the lower shell 6 is impacted, the upper shell 5 will cause the first telescopic column 8 and the second telescopic column 16 to contract. At this time, the spring 15 will also be stressed, causing the connecting frames 12 on both sides of the top plate 14 to open. The connecting frames 12 are connected to the top plate 14 by the rotating column 13, allowing the connecting frames 12 to form a tension. When the connecting frame 12 opens, it will cause the sliding column 11 to slide in the sliding groove 9. Limiting grooves 10 are provided on both sides of the sliding groove 9 to prevent the sliding column 11 from sliding out of the sliding groove 9 due to the force of the connecting frame 12 opening. Friction blocks 7 are provided on the outer surface of the lower shell 6 to increase friction and prevent the cardboard box from sliding too much, thus protecting the box body from excessive wear and making it more wear-resistant. When it is placed firmly, the spring 15 will rebound and drive the upper shell 5 and the lower shell 6 to return to their original positions.

[0027] Honeycomb holes 3 are formed in the paper layer 2 of the cardboard shell 1. The hollow structure of the paper layer 2 is a triangular hollow plate, which is interspersed in the honeycomb structure. The hollow triangular honeycomb structure itself has good compressive strength, and its hexagonal honeycomb shape can evenly distribute the pressure to the entire structure. The addition of the triangular plate slot structure, especially after the edges of the triangular plates are connected or matched with the edges of the honeycomb structure, can provide additional support and reinforcement for the honeycomb structure, further enhancing the overall compressive strength. The support layer 4 at the lower end can improve the external support effect. A relatively hard paper material is set on the outer surface of the cardboard shell 1, which, together with the upper and lower shells, can have better wear resistance.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
