According to the performance characteristics of the basic structural elements of the paper tray and the environmental protection paper tray, the structure design of the paper tray can be carried out. The analysis of the design points is as follows, let's take a look with Baihua.
(1) Fixed supporting surface. This is a basic point in the design of the paper support structure. The fixed support surface can be determined according to the requirements of the packaged product, the external dimensions and the internal dimensions of the outer packaging. For example, to design a paper tray package for electrical products, the length, width and corresponding structure of the paper tray can be determined according to the external dimensions of the package and the internal dimensions of the outer packaging, and the fixed supporting surface of the paper tray can be determined accordingly. . At the same time, it is necessary to understand whether the focus of packaging is strength or cushioning. The packaging of some heavy and high-strength products focuses on strength, but as a cushioning package, its cushioning performance must also be maintained, and the packaging side of some valuable products The focus is on cushioning, and its packaging must also have a certain strength. In the design, the two should be properly combined, and the appropriate base points should be selected according to the shape and structure of the packaged product, the center of gravity and the strength, and then the fixed support surface should be determined by these base points.
(2) Cavity and stiffener. The cushioning effect of the paper tray is mainly realized by offsetting the external force by the elastic deformation of the paper wall when it is impacted. The elasticity of the paper tray material itself is not high, mainly depends on the product's stiffener design and the cushioning cavity formed. The design of the cavity and stiffeners plays a vital role in the elastic deformation of the paper tray, that is, the cushioning capacity. , And the basic basis for the design of the cavity and the ribs is the shape and purpose of the product itself.
In the paper support structure design, a cavity is provided to ensure the dynamic cushioning performance of the paper support, and the reinforcement ribs are provided to increase the strength of the paper support. Several cavities with simple shapes and good dynamic cushioning performance are evenly distributed in the paper support structure to buffer, stabilize and improve the strength. For large-area cavities, the structure of the paper support structure is unstable and the strength is reduced. Several or symmetrical reinforcement ribs can be installed to solve such problems. The cavity and reinforcement ribs should be set up to fully consider the problems of convenient production, simple processing, uniform distribution, and uniform distribution of the gravity of the product.
