Equipment and method for detecting performance of artificial board

Abstract

The invention provides equipment for detecting performance of an artificial board, and a detection method using the equipment. The equipment comprises a rectangular framework, a supporting system, a movable supporting frame and a data acquisition system, wherein a base plate is arranged on the lower bottom surface of the rectangular framework; a guide rail is arranged on the upward surface or outer side surface of the rectangular framework; the base plate closes the lower bottom surface of the rectangular framework, and is provided with an air suction hole; the supporting system comprises a plurality of supporting battens which are arranged on the base plate in a dismountable mode; the movable supporting frame comprises two supporting rods and a cross beam; the lower ends of the two supporting rods are embedded in guide rails which are arranged on two opposite framework rods on the rectangular framework, and the upper ends of the two supporting rods are fixedly connected with two ends of the cross beam; a guide rail is arranged on the cross beam, and is vertical to the guide rail on the rectangular framework; and the data acquisition system comprises a displacement sensor which is arranged on a guide rail arranged on the movable supporting frame. By the equipment and the method provided by the invention, a board to be detected can be conveniently arranged, and the mechanical properties of the artificial board can be detected under the action of measurement equally-distributed loads and the like.

Description

technical field [0001] The invention relates to the technical field of wood-based panel detection for structures, relates to performance testing equipment for wood-based panels for structures, and also provides a detection method for testing the performance of wood-based panels using the detection equipment. technical background [0002] Structural wood-based panels are an important part of wood-based panels, mainly including plywood and laminated veneer lumber with veneer as the base material, and oriented strand board with shavings as the base material. Compared with ordinary wood-based panels, in addition to requiring good appearance properties, physical properties, surface properties, durability (aging performance), and processing properties, structural wood-based panels have newly added mechanical properties such as uniform loads, concentrated static loads, and impact loads. The test of performance indicators also puts forward higher requirements for mechanical performa...

AI Technical Summary

Problems solved by technology

The existing uniform load testing device is very inconvenient for installation, fixing and testing of plates of various specifications. Difficult to adapt; most of the tests of concentrated static load and impact load use the mechanical testing machine to record the load value, and then record the plate deformation by manually reading the value of the thousands gauge. Due to the limitation of the test range of the standard mechanical testing machine, the size of the plate to be tested It can only meet the test requirements of small test pieces, and it needs to cooperate with special fixtures

In order to meet the test of large-size plates, a standard mechanical testing machine with a higher tonnage is used. In this way, not only the test accuracy is low, but the test cost is too high, which will cause the phenomenon of big horses and small carts

[0007] In addition, there is no multifunctional testing equipment in the prior art that can simultaneously test the uniform load, concentrated load and impact load of the plate
