Description

Technical Field

[0001] The utility model belongs to the technical field of environmentally friendly packaging, and in particular relates to a molded buffer environmentally friendly base. Background Art

[0002] With the popularization of plastic ban and carbon emission requirements, the demand for environmentally friendly packaging for home appliances in the market is relatively high. At present, most of the environmentally friendly packaging on the market adopts honeycomb + corrugated or hollow board bottom box structure as a buffer packaging solution, and a few use EPE materials as a buffer structure. The former is limited by paper honeycomb materials and cannot withstand multiple impacts (honeycomb is crushed and cannot be restored after falling and impact). The latter is only used as a local buffer because of its high price and soft material. After long-term stacking, its deformation is large and there is a risk of box collapse. Both solutions require manual secondary pasting during production, and mechanical automation cannot be achieved. Both are prone to damage when impacted by sharp objects or forced dragging. Due to structural problems, home appliances have reinforcing rib structures at the bottom or are not on the same plane. Ordinary packaging protection is only a local buffer force, which cannot provide good protection for home appliances.

[0003] In order to solve the above technical problems, the utility model designs a molded buffering environmentally friendly base. Utility Model Content

[0004] The utility model provides a molded buffer environmental protection base, which aims to solve the problem that the existing environmental protection packaging base is easily damaged by impact or forced dragging and damages the carrier product.

[0007] Based on the above technical solution, the upper cover and the bottom shell are both formed by sawdust molded material.

[0008] Based on the above technical solution, the foaming buffer layer is made of polyurethane foaming material or airbag material.

[0009] Based on the above technical solution, the bottom corner groove is used as the bottom corner for placing the carrier product.

[0010] Based on the above technical solution, there is a gap between the upper cover and the bottom shell.

[0011] Preferably, the widths of the upper cover mounting groove and the strap mounting groove are consistent.

[0019] The utility model is further described below with reference to the accompanying drawings and examples:

[0020] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium.

[0023] See also Figure 1 The utility model provides a technical solution: a molded buffer environmental protection base, characterized in that it includes an upper cover 1, a bottom angle groove 2, a foam buffer layer 3, a bottom shell 4, an upper cover installation groove 5, a strapping belt installation groove 6 and a strapping belt;

[0024] The bottom shell 4 is provided with an inner cavity 41, the foaming buffer layer 3 is sprayed in the inner cavity 41, the upper cover 1 is buckled on the bottom shell 4, the four corners of the upper cover 1 are provided with bottom corner grooves 2, the surface of the upper cover 1 is provided with an upper cover mounting groove 5, the side and bottom surfaces of the bottom shell 4 are provided with strapping tape mounting grooves 6, and the strapping tape is embedded in the upper cover mounting groove 5 and the strapping tape mounting groove 6.

[0025] The upper cover 1 and the bottom shell 4 are formed by using wood chip molding material.

[0026] The foaming buffer layer 3 is made of polyurethane foaming material or airbag material.

[0027] The bottom corner groove 2 is used as the bottom corner for placing the carrier product.

[0028] There is a gap between the upper cover 1 and the bottom shell 4 .

[0029] The widths of the upper cover mounting groove 5 and the strap mounting groove 6 are consistent.

[0030] During the production process, the bottom shell 4 is first placed. The bottom shell 4 is formed by sawdust molding material. The foam buffer layer 3 is sprayed in the inner cavity 41. Then the upper cover 1 is installed immediately. The foam buffer layer 3 prevents overflow. When the bottom shell 4 is sprayed with the foam buffer layer 3, the upper cover 1 is instantly closed to prevent the foam buffer layer 3 from overflowing. Then the carrier product is placed on the upper cover 1, and the four corners of the carrier product are inserted into the bottom corner grooves 2. Finally, the strapping tape is inserted into the installation groove 5 and the strapping tape installation groove 6 to fix the carrier product to be placed. On the one hand, the strapping tape fixes the carrier product on the upper cover 1, and on the other hand, the foam buffer layer 3 plays a limiting role between the upper cover 1 and the bottom shell 4.

[0031] When the carrier product falls or receives an impact, the upper cover 1 and the carrier product together descend through the assembly gap space between the upper cover 1 and the bottom shell 4, squeezing the foam buffer layer 3, increasing the force-bearing area of ​​the carrier product when it falls, and converting local force into overall force. At the same time, the foam buffer layer 3 is a polyurethane foam material, which is used as a filling buffer layer. When the carrier product falls and is subjected to force, it can absorb energy and buffer.

[0032] The bottom shell 4 is made of molded wood chip bottom shell, which has high bending strength and can reduce the pulling of the strapping belt, the damage caused by the bottom dragging and the impact of sharp objects. The whole is tightened and fixed with strapping belt, which is convenient for disassembly, assembly and recycling after scrapping, and can realize automated production. Bolt connection or bayonet limiter can also be used to replace the strapping belt.

[0033] Alternatively, the foaming buffer layer 3 can use a polyurethane foam material filled with an airbag in the inner cavity 41 as a filling buffer layer, which can be used as an energy-absorbing buffer when the carrier product falls and is subjected to force. The polyurethane filling buffer material is environmentally friendly and meets the requirements of foreign plastic restrictions and carbon emissions.

[0034] The present invention is described above by way of examples, but the present invention is not limited to the above specific embodiments, and any changes or modifications based on the present invention belong to the scope of protection required by the present invention.
