According to the performance characteristics of the basic structural elements of pulp molded products, the structural design of pulp molded products can be carried out, and the key design points are analyzed as follows.
(1) fix the support surface. This is the most basic point in the structural design. The fixed support surface can be determined according to the requirements of the packaged product, the external dimension and the internal dimension of the outer package. For example, to design a paper packaging for an electrical product, you can
The length, width, height and corresponding structural form of the paper mold products are determined according to the external dimension of the packaged products and the internal dimension of the outer package, and the fixed supporting surface of the paper mold products is determined accordingly. At the same time, we should understand that the key point of packaging is to
In terms of degree, it is still in buffering. Some products with large weight and high strength focus on strength, but as buffering packaging, its buffering performance must also be guaranteed. "While some valuable products focus on buffering, and its packaging must also be strong
Degree. In the design, the two should be properly combined, and the appropriate base points should be selected according to the shape structure, gravity center and strength of the packaged product, and then the fixed support surface should be determined by these base points.
(2) cavity and stiffener. The buffering effect of the paper mold packaging is mainly realized by using the elastic deformation of the paper wall to slow down and counteract the external force when it is impacted. The elasticity of the paper mold material itself is not high, which mainly depends on the design and formation of the stiffener of the product
The design of buffer cavity, cavity and stiffener plays an important role in the elastic deformation of paper mold packaging products, that is, buffer capacity. The basic basis for the design of cavity and stiffener is the shape and use of the product itself. Setting the type in the structure design of paper mould
The cavity ensures the dynamic buffering performance of the paper mold, while the stiffener is set to increase the strength of the paper mold itself. Several cavities with simple shape and good dynamic buffering performance are uniformly distributed in the paper mold structure, which plays the role of buffering, stabilizing and improving the strength
In order to solve the problems of structural instability and strength decline caused by large-area cavity to paper mold structure, several or symmetrical stiffeners can be set up. The layout of cavity and stiffeners should fully consider the convenience of production, simple processing, uniform distribution and production
The gravity of the product is evenly distributed.
