Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of a compression resistance detection mechanism for a high-strength anti-deformation corrugated paper box, and in particular to a compression resistance detection mechanism for a high-strength anti-deformation corrugated paper box. Background Art
[0002] Corrugated boxes are mainly made of corrugated cardboard, which includes face paper, corrugated core paper and lining paper.
[0003] In the existing technology, the stress conditions of cartons in actual stacking storage or transportation environments are complex and multi-dimensional. Not only do they have to withstand the vertical gravity pressure brought by the cartons directly above, but at the same time, the surrounding areas and four corners will also receive supporting reaction forces from adjacent cartons. The interaction of such multi-directional forces significantly increases the pressure value that the entire carton can withstand compared to the single-direction stress condition, thereby ensuring that the carton has sufficient stability and pressure resistance during actual application, so as to effectively protect the items loaded inside from damage.
[0004] However, most of the existing cardboard compressive strength testing devices have certain limitations. When conducting tests, they usually only use the method of squeezing the cardboard downward to perform the test operation, focusing only on the mechanical performance of the cardboard in a single dimension: vertical compression. The compressive strength data obtained by this test method is difficult to accurately and comprehensively reflect the actual pressure that the cardboard can withstand in actual use scenarios. This leads to a significant difference between the test results and the actual compressive strength of the cardboard. It cannot provide a sufficiently accurate and reliable technical basis for the quality assessment, design optimization and practical application of the cardboard, thereby affecting the overall development of the carton industry and the advancement of technological progress to a certain extent.
