Description

Pulp molded buffer for flat panel display products

technical field

The utility model relates to a cushion for a package, in particular to a cushion molded with pulp and used for packaging flat panel display products, especially liquid crystal display products above 32 inches.

Background technique

With the rapid development of flat panel display technology, various large-size flat panel display products (such as liquid crystal displays, LCD TVs, plasma TVs, etc.) The bottom edge is narrow and long, and the force is relatively concentrated, which requires high cushioning capacity of the packaging. Therefore, it poses a challenge to the design of the cushioning packaging structure.

Foamed plastic is a common cushioning package. Ordinary foamed plastics have low density and insufficient strength to meet the packaging requirements of large-size LCD TVs. Currently, the cushioning parts used to package such LCD TVs above 32 inches EPP is used, which has high strength and certain toughness. After proper shape design, it can withstand large-sized LCD TVs. Although the EPP material can be recycled, it is difficult for users to distinguish it from ordinary foam materials, and it is difficult to recycle in the actual use process, and it is difficult to degrade in the natural environment, which will cause environmental pollution. High, making packaging costs high.

Pulp molded cushioning materials are easy to recycle and have no pollution to the environment. In recent years, as a substitute for foaming materials, they have been widely used in packaging cushioning parts, especially in small and medium-sized electronic products. In large-scale electronic products, still can't use on the flat display product packaging of large size, this is to be subjected to the limitation of the manufacturing process of pulp molding, with the pure pulp molding buffer strength (pulp molding thickness) in the prior art Limited) and buffer height (only 17CM-18CM) cannot meet the buffer requirements of heavier large-size flat panel display products. For a 32-inch LCD TV, the weight is about 38 kg. During transportation The impact force generated by stacking and falling requires the strength of the cushioning parts to far exceed the cushioning requirements of small and medium-sized electronic products, especially at the corners where the force is concentrated, problems such as compression or even cracking may occur due to insufficient strength , and then cause damage to the packaged product, and the cushioning effect cannot be realized.

Therefore, when packaging large-size flat-panel display products, EPP materials that are expensive and difficult to recycle are still used, while low-cost and non-polluting pulp molding materials cannot be used.

Contents of the invention

The purpose of the utility model is to provide a pulp molded buffer support which can be used in the packaging of large-size flat panel display products, which can reduce the packaging cost and is beneficial to environmental protection.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a pulp molded buffer bracket for flat panel display products, including a buffer body, and the body is provided with an accommodating cavity for matching the shape of a corner shell of the packaged body. Cavity, a plurality of reinforcing ribs are respectively provided around the cavity and the bottom of the body, the top of the body is provided with flanging, including a dustpan-shaped outer support wrapped around the bottom of the body, the The inner side of the outer support is provided with a cavity for accommodating the bottom of the main body, and the opening direction matches the opening direction of the main body. The outer wall surfaces of the outer support are in a plane that fits with the corresponding inner walls of the corners of the outer packaging carton.

In the above technical solution, the outer support is in the shape of a dustpan, and is generally surrounded by the bottom plate, left and right side plates and end side plates perpendicular to each other. The opening direction of the outer support matches the opening direction of the body, that is, according to the corner of the body The orientation determines the opening direction of the outer support (the opening direction of the main body matches the corner of the packaged body), which constitutes the wrapping of the outer support to the outside of the bottom of the main body. The outer support can usually be folded or spliced with paper materials such as corrugated cardboard or honeycomb board. Composition; when the corners of the outer packaging carton are squeezed, the impact force is transmitted from the carton to the outer support, and then transmitted from the outer support to the inner pulp molded body, which strengthens the impact strength of the pulp molded body; at the same time , the outer wall of the outer support is a plane that fits with the inner wall of the carton, and the force bearing area is much larger than the contact area between the ribs at the bottom of the body and the carton, and the impact force on the body in the outer support cavity is reduced by increasing the force bearing area, Avoid local pressure accumulation, prevent the cracking of the pulp molded body, and realize the cushioning packaging of pulp molded parts for large-size flat panel display products.

In the above technical solution, an adhesive layer is provided at the joint between the bottom of the body and the inner wall of the outer support, and the inner wall of the outer support is fixedly connected to the outer wall of the bottom of the body through the adhesive layer. Through the adhesive layer (generally composed of adhesive glue), the outer support and the main body are integrated to increase the compressive strength. At the same time, the adhesive layer can increase the toughness of the buffer (main body + outer support) and improve the anti-cracking ability of the main body.

Another technical solution is that the tops of the side walls constituting the outer bracket respectively extend into the flanges on the top of the main body to form a snap-fit connection between the outer bracket and the main body.

In the above technical solution, the outer support is formed by vertically folding the corrugated cardboard of the bottom plate, the left and right side plates and the end side plates, and the left and right side plates are respectively provided with inwardly folded edges at the ends of the end side plates. The folded edges on both sides are respectively fixedly connected with the end side panels. The fixed connection can be fixed by adhesive, or fixed by staples, so that the outer support forms a buffer structure similar to a double layer at the end, and improves the buffer strength of the corner of the main body.

Due to the use of the above technical solutions, the utility model has the following advantages compared with the prior art:

1. Because the utility model increases the outer support structure wrapped in the bottom of the pulp molding body, the impact resistance strength of the pulp molding body is enhanced, and at the same time, the outer wall surface of the outer support that fits and cooperates with the inner wall of the corner of the outer packing box , increase the load-bearing area of the buffer (body + outer support), avoid the accumulation of local pressure, and improve the ability to prevent the body from cracking; thus making the pulp molded buffer used in the buffer packaging of large-size flat panel display products, broadening the scope of pulp The scope of use of molded parts reduces the cost of product packaging and is conducive to environmental protection;

2. Through the setting of the adhesive layer, on the one hand, the body and the outer bracket are integrated to enhance the buffer strength of the entire buffer; deformation ability;

3. Wrap the bottom of the main body with the outer support with a flat surface, so that the surface of the entire buffer is smooth and the aesthetics is greatly improved. At the same time, when the surface of the outer packing box is pressed, the smooth surface of the outer support and the larger force-bearing surface (Compared with the area of the reinforcing rib at the bottom of the pulp molding in the past), it avoids indentation on the surface of the outer packaging box, and is more in line with the manufacturer's requirements for the appearance of the outer packaging surface.
