Description

Technical Field

[0001] The invention relates to the technical field of wooden floor production, and in particular discloses a device and a method for detecting deformation of a wooden floor after absorbing water. Background Art

[0002] Water absorption and expansion deformation refers to the phenomenon that the volume of a material increases and expands after absorbing liquid. The smaller the expansion, the stronger the material's ability to resist deformation. Water absorption and expansion rate is an extremely important quality indicator of artificial boards. At present, in the production process of artificial wood flooring, quality inspection is one of the necessary processes, especially the detection of the deformation performance of wood flooring after water absorption. The existing process of detecting the deformation performance of wood flooring after water absorption is usually to cut a certain amount of wood board samples and immerse them in water. After immersion for a certain period of time, the ratio of the thickness difference before and after water absorption to the thickness before immersion is measured.

[0003] After searching, the invention patent with publication number CN117969330A discloses a detection method and device for testing the water absorption rate of floors, including a detection unit and a sample fixing device; by placing the floor specimen in the sample fixing device, ensuring that the surface of the specimen is perpendicular to the water surface, and the specimen is not restricted in all directions, it can fully absorb moisture and expand, simulate the water absorption state, reflect the water resistance of the floor, and provide efficient and reliable test results.

[0004] Based on the above search and in combination with the prior art, it is found that the prior art uses a direct immersion method to detect wooden floors. On the one hand, it is impossible to perform deformation detection processing on different types of wooden floors at the same time, and it is impossible to intuitively observe the water absorption and deformation performance of different types of wooden floors. On the other hand, after the wooden floor is soaked, it is necessary to use a weighing method to detect whether there is a weight change before and after, so as to detect whether the wooden floor absorbs water and expands and deforms. However, the above method cannot measure whether it finds expansion deformation in the first time. The entire detection process has a large degree of manual participation and a low degree of automation. Therefore, it is necessary to propose a device for detecting the deformation of wooden floors after water absorption and a detection method thereof to improve the above problems.
