Release Date:2018-12-22All paper barrel production factory Foshan Danqi Paper Products Co., Ltd. takes you to learn about the strength and deformation design of paper drums
fibre drum The strength of the paper barrel is not only related to the raw materials used, but also to the thickness of the paper barrel and the magnitude of the axial force acting on it. With a certain material and circumference, the vertical compression strength of the paper barrel should be greater than 8000N, the lateral compression strength should be greater than 4000N, and the puncture strength should be greater than 10N
The deformation of paper drums is related to their stiffness, that is, whether the stiffness coefficient during design is reasonable. The size of the deformation of the paper barrel is directly proportional to the lateral pressure and circumferential length of the paper barrel, and inversely proportional to the elastic modulus, thickness, and number of layers of the paper barrel. That is to say, the greater the lateral pressure acting on the paper barrel and the longer the circumference, the greater the deformation of the paper barrel; The high elastic modulus, number of layers, and thickness of paper drums result in minimal deformation. From this, it can be concluded that in order to reduce the stress on the paper drum, the number of layers in the drum and the thickness of the cardboard should be increased. The higher the stiffness coefficient of the paper bucket, the greater the stiffness of the paper bucket. The material should be selected from cardboard with high elastic modulus, multiple layers of paper thickness, and a relatively small diameter structure.
