Simple fiberboard bending tester and testing method

Abstract

The invention discloses a simple fiberboard bending tester and a testing method. The tester comprises a support, a bench scale, a pressure mechanism and a sample loading carrier, wherein the sample loading carrier is placed on the bench scale, the sample loading carrier is provided with two support cross bars for supporting the two ends of a fiberboard, and the pressure mechanism is arranged above the sample loading carrier and is liftably arranged on the support. According to the invention, when the fiberboard is detected, the pressure mechanism goes down to apply pressure on the central portion of the fiberboard, the fiberboard generates a certain elastic deformation, the fiberboard restores the elasticity because of the interaction of power, the two support cross bars receive the pressure generated by the elasticity recovery of the fiberboard, the pressure is transmitted to the bench scale, and the bench scale displays the bending resistance data. The tester utilizes the pressure mechanism and the sample loading carrier to simulate the bending handle, and utilizes the display of the bench scale display screen to calibrate the result data, thus the bending resistance of the fiberboard can be simply detected, and the bending resistance of products can be calibrated accurately.

Description

technical field [0001] The invention relates to the technology in the field of bending test equipment, in particular to a simple fiberboard bending tester and a testing method. Background technique [0002] Fiberboard is a wood-based panel made by interweaving fibers and utilizing its inherent adhesive properties. Adhesives and (or) additives can be applied during the manufacturing process. Cellulose fiber or regenerated fiber can be used as the fiber raw material, and the fiberboard produced by regenerated fiber from plastic bottle flakes can realize the recycling of waste plastics, replace petroleum primary products, effectively reduce waste plastic pollution and reduce the consumption of petroleum primary products. [0003] Fiberboard is widely used in the fields of shoe materials, furniture, and construction: shoe materials are mainly used in the midsole, also known as fiber midsole, and the hardness of its products has a great impact on the comfort of shoes; furniture i...

Problems solved by technology

[0005] At present, there is no simple test standard and instrument for the bending performance of fiberboard that can be directly used in the workshop and inspection process. The bending performance of fiberboard is mostly confirmed by hand feeling, and the test is carried out through sample comparison and experience judgment. This method of hand feeling comparison and confirmation has the following disadvantages: in the process of sample comparison and sample transfer, due to factors such as damage and human judgment, the results are different, and it is difficult to standardize the structure
