Description

Technical Field

[0001] The utility model relates to the field of corrugated paperboards, and particularly to an anti-staining and waterproof composite corrugated paperboard. Background Art

[0002] A corrugated paperboard is a material composed of multiple layers of adhesives, mainly consisting of a wavy core paper interlayer and paperboard. It has good mechanical strength and buffering performance, can effectively protect goods from collision and dropping during handling. It is light, space-saving, can be made into various shapes and sizes of packages, is not sensitive to temperature and humidity changes, and is suitable for various packaging needs. Corrugated paperboards are widely used in manufacturing cartons and other packaging materials, providing protection for product packaging and transportation, and are an indispensable important material in the packaging industry.

[0003] Currently widely used corrugated paperboards usually adopt a box structure for easy storage and accommodation of various items. However, during transportation and movement, the corners of corrugated cartons are often easily impacted by external objects, resulting in corner breakage or deformation, which may further damage the internal items. To solve this problem, we urgently need to design a corrugated paperboard with higher corner structural strength to cope with the complex and changeable handling environment and ensure the safety and integrity of items during transportation. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide an anti-staining and waterproof composite corrugated paperboard to solve the technical problem that the corners of corrugated cartons are easily collided by external objects during transportation and movement, resulting in breakage or deformation at the corners.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an anti-staining and waterproof composite corrugated paperboard, including a paperboard main body. The paperboard main body includes a first core layer and a second core layer. An intermediate layer and a reinforcement layer are arranged between the first core layer and the second core layer. A reinforcement mechanism is arranged on the surface of the paperboard main body. The reinforcement mechanism includes a first reinforcement plate and a second reinforcement plate. Plug blocks are arranged on the surface of the first reinforcement plate, and slots are formed on the surface of the second reinforcement plate.

[0006] By adopting the above technical solution, the tight insertion of the plug blocks and the slots firmly fixes the first reinforcement plate and the second reinforcement plate at the required positions. These two reinforcement plates provide solid support for the inner side of the right-angle bending structure, significantly enhancing the structural strength of the right-angle bending part of the corrugated carton.

[0007] Furthermore, the material of the reinforcement layer is stainless steel, which is used to provide the structural strength at the bending part of the paperboard main body.

[0008] By adopting the above technical solution, the reinforcement layer is made of stainless steel, significantly enhancing the structural strength at the bending part of the cardboard body. Due to its excellent compressive and tensile properties, stainless steel can effectively disperse forces when the cardboard body is subjected to external impacts or squeezes, protecting the corrugated cardboard box from being damaged or deformed at the bending part.

[0009] Furthermore, the first reinforcement plate and the second reinforcement plate form a right-angled triangle structure, and the first reinforcement plate and the second reinforcement plate are fixedly engaged through insertion blocks and slots.

[0010] By adopting the above technical solution, it can closely fit the right-angled bending part of the corrugated cardboard box, providing stable support. This structural design enhances the local strength of the bending part, helping to prevent the cardboard box from being deformed or damaged during handling.

[0011] Furthermore, the first reinforcement plate and the second reinforcement plate are both made of cardboard.

[0012] By adopting the above technical solution, this makes the reinforcement plate consistent with the main material of the corrugated cardboard box, enhancing the overall coordination. Using the same material helps to reduce the problem of stress concentration and avoid structural weaknesses caused by differences in material properties.

[0013] Furthermore, multiple reinforcement mechanisms are provided, and the multiple reinforcement mechanisms are arranged in an equidistant linear pattern along the height line of the cardboard body.

[0014] By adopting the above technical solution, this can provide a more comprehensive reinforcement effect. The multiple reinforcement mechanisms are arranged in an equidistant linear pattern along the height line of the cardboard body, ensuring that the corrugated cardboard box can be evenly supported and reinforced at each key part, thereby effectively improving the overall structural stability.

[0015] Furthermore, a sandwich layer is provided on the outer sides of the first core layer and the second core layer, and a face paper is provided on the outer side of the sandwich layer.

[0016] By adopting the above technical solution, the number of layers and the thickness of the corrugated cardboard are increased, thereby improving its heat insulation, sound insulation and buffering properties. The sandwich layer, as an additional structural support, helps to enhance the overall stability and load-bearing capacity of the cardboard.

[0017] Furthermore, a protective film layer is attached to the outer surface of the face paper, and the first core layer, the second core layer, the intermediate layer, the reinforcement layer, the sandwich layer, the face paper and the protective film layer are all adhered through an adhesive.

[0018] By adopting the above technical solution, attaching the protective film layer to the outer surface of the face paper significantly enhances the waterproof and anti-fouling capabilities of the corrugated cardboard. The protective film layer can effectively block moisture and stains, protecting the cardboard from moisture and pollution, thus maintaining the stability of its structure and the cleanliness of its appearance.

[0019] In summary, the utility model mainly has the following beneficial effects:

[0020] Through the reinforcement layer and the reinforcement mechanism, the first reinforcement plate and the second reinforcement plate can be fixed in position inside the right-angle bending structure of the corrugated cardboard box by inserting the insertion block into the slot, providing a stable support for it, significantly enhancing the structural strength of the right-angle bending part, making it more capable of withstanding external impacts. At the same time, the stainless steel reinforcement layer inside the cardboard body and the reinforcement plate form a double protection, jointly improving the compressive capacity of the corrugated cardboard at the bending part. This reinforcement method can effectively cope with the complex and changeable handling environment, significantly reducing the risk of corner breakage and deformation of the corrugated cardboard box during transportation and use, and ensuring the safety and integrity of the internal items.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the utility model. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the utility model and should not be construed as limiting the utility model.

[0027] The embodiments of the utility model will be described below according to its overall structure.

[0028] Embodiment 1:

[0029] An anti-fouling and waterproof composite corrugated cardboard, as Figures 1-4As shown, it includes a cardboard main body 1. The cardboard main body 1 includes a first core layer 101 and a second core layer 102. An intermediate layer 103 and a reinforcement layer 104 are arranged between the first core layer 101 and the second core layer 102. A reinforcement mechanism 2 is arranged on the surface of the cardboard main body 1. The reinforcement mechanism 2 includes a first reinforcement plate 201 and a second reinforcement plate 202. An insertion block 203 is arranged on the surface of the first reinforcement plate 201, and a slot 204 is opened on the surface of the second reinforcement plate 202. The insertion block 203 is tightly inserted into the slot 204, so that the first reinforcement plate 201 and the second reinforcement plate 202 are firmly fixed in the required positions. These two reinforcement plates provide a solid support for the inner side of the right-angle bending structure, significantly enhancing the structural strength of the right-angle bending part of the corrugated cardboard box. At the same time, combined with the reinforcement layer 104 made of stainless steel inside the cardboard main body 1, the stability of the corrugated cardboard at the bending part is further improved. This double reinforcement setting enables the corrugated cardboard to better cope with the complex and changeable handling and use environments, effectively reducing the risk of corner damage and deformation.

[0030] Refer to Figure 4 , the material of the reinforcement layer 104 is stainless steel, which is used to provide the structural strength at the bending part of the cardboard main body 1. The reinforcement layer 104 is made of stainless steel, significantly enhancing the structural strength at the bending part of the cardboard main body 1. Due to its excellent compressive and tensile properties, when the cardboard main body 1 is subjected to external impact or extrusion, stainless steel can effectively disperse the force, protecting the corrugated cardboard box from being damaged or deformed at the bending part. At the same time, the introduction of the stainless steel reinforcement layer 104 also greatly improves the durability and service life of the corrugated cardboard. The high corrosion resistance of stainless steel enables the cardboard main body 1 to better adapt to the humid and changeable environment and maintain its structural stability for a long time. It not only strengthens the load-bearing capacity of the corrugated cardboard box but also makes it show higher durability in various complex and changeable handling and use environments.

[0031] Refer to Figure 1 、 Figure 2 、 Figure 3 , the first reinforcement plate 201 and the second reinforcement plate 202 are in a right-angled triangle structure. The first reinforcement plate 201 and the second reinforcement plate 202 are inserted and fixed through the insertion block 203 and the slot 204, and can closely fit the right-angle bending part of the corrugated cardboard box to provide stable support. This structural design enhances the local strength of the bending part, helping to prevent the cardboard box from deforming or being damaged during handling. At the same time, the first reinforcement plate 201 and the second reinforcement plate 202 are inserted and fixed through the insertion block 203 and the slot 204. This connection method is simple and firm. The insertion setting is not only convenient for quick assembly but also ensures that the reinforcement plates always maintain a stable position during the use of the cardboard box, thus continuously and effectively enhancing the structural strength of the cardboard box.

[0032] Refer to Figure 1 、 Figure 2 、 Figure 3, The materials of the first reinforcement plate 201 and the second reinforcement plate 202 are both cardboard. This makes the reinforcement plates consistent with the main material of the corrugated cardboard box, enhancing the overall coordination. Using the same material helps reduce the problem of stress concentration and avoid structural weaknesses caused by differences in material properties. At the same time, the cardboard material is relatively light and will not significantly increase the overall weight of the corrugated cardboard box, which has a positive impact on energy efficiency and cost during transportation and handling. Cardboard has good plasticity and environmental friendliness, which is not only convenient for processing and forming but also meets the current requirements for the environmental friendliness of packaging materials.

[0033] Refer to Figure 1 , Figure 2 , Figure 3 , There are multiple reinforcement mechanisms 2. The multiple reinforcement mechanisms 2 are arranged linearly at equal intervals along the height line of the cardboard main body 1. This can provide a more comprehensive reinforcement effect. The multiple reinforcement mechanisms are arranged linearly at equal intervals along the height line of the cardboard main body 1, ensuring that the corrugated cardboard box can be evenly supported and reinforced at each key part, thus effectively improving the overall structural stability. At the same time, this arrangement of reinforcement mechanisms at equal intervals also optimizes the load-bearing distribution of the cardboard box, enabling the weight to be more evenly distributed among each reinforcement point, reducing the risk of excessive single-point stress. This layout not only improves the compressive strength of the cardboard box but also helps extend the service life of the cardboard box, making it more adaptable to the changing handling and use environments.

[0034] Embodiment 2:

[0035] Refer to Figure 1 , Figure 4 , There is a sandwich layer 105 on the outer sides of the first core layer 101 and the second core layer 102, and there is a face paper 106 on the outer side of the sandwich layer 105, increasing the number of layers and thickness of the corrugated cardboard, thereby enhancing its heat insulation, sound insulation and buffering performance. The sandwich layer 105 serves as an additional structural support, helping to enhance the overall stability and load-bearing capacity of the cardboard. At the same time, setting the face paper 106 on the outer side of the sandwich layer 105 not only improves the appearance quality of the corrugated cardboard, making it more beautiful, but also plays a certain protective role. The face paper 106 can resist slight friction and scratches, extending the service life of the corrugated cardboard. The face paper 106 can also be printed with various patterns and information as needed, enhancing the identification and information content of the cardboard.

[0036] Refer to Figure 1 , Figure 4, a protective film layer 107 is attached to the outer surface of the facial paper 106. The first core layer 101, the second core layer 102, the intermediate layer 103, the reinforcement layer 104, the sandwich layer 105, the facial paper 106 and the protective film layer 107 are adhered to each other through an adhesive. The attachment of the protective film layer 107 to the outer surface of the facial paper 106 significantly enhances the waterproof and anti-fouling capabilities of the corrugated board. The protective film layer 107 can effectively block moisture and stains, protecting the board from moisture and contamination, thereby maintaining the stability of its structure and the cleanliness of its appearance. At the same time, all levels of the structure, including the first core layer 101, the second core layer 102, the intermediate layer 103, the reinforcement layer 104, the sandwich layer 105, the facial paper 106 and the protective film layer 107, are tightly adhered to each other through an adhesive. This connection method ensures a firm combination between all levels, improves the integrity and structural strength of the board, enables it to better withstand external pressure, and extends its service life.

[0037] The implementation principle of the present utility model is as follows: First, the corrugated board is bent into a right-angle structure of a corrugated cardboard box. Subsequently, through the insertion of the insertion block 203 into the insertion slot 204, the first reinforcement plate 201 and the second reinforcement plate 202 are fixed in position to support the inner side of the right-angle bending structure, providing the structural strength of the right-angle bending structure of the corrugated cardboard box. At the same time, in cooperation with the reinforcement layer 104 made of stainless steel inside the cardboard body 1, the structural strength of the bending part of the corrugated board is jointly improved to cope with the changing handling and use environment, reducing the occurrence of corner breakage and deformation.

[0038] The reinforcement layer 104 only exists at the bending part of the corrugated board, which is beneficial to reducing the production cost of the corrugated board.

[0039] Parts not involved in the present utility model are the same as or can be implemented using the prior art, and will not be elaborated here.
