Problems solved by technology

[0002] At present, domestic wood structure and wood product suppliers and manufacturers all use manual visual grading method when grading the strength of dimension lumber and glued wood laminates. The strength of wood is highly discrete, the grading is not accurate, and the speed of workers grading the strength is very slow. This speed sometimes even becomes a bottleneck restricting the processing capacity of the production line, seriously affecting the production speed.

Abstract

The invention discloses a device for wood intensity grading. The device is characterized in that to-be-detected wood is placed on outer rims of a plurality of transmission rollers, a rail support is fixedly arranged at the middle portion of the upper surface of a rigid pedestal, a hoisting mechanism is rotatably connected with the upper middle portion of the guide support and is connected to the upper end of a sling, the lower end of the sling is connected with a standard load hammer, a light screen sensor is fixedly arranged on the upper surface of the rigid pedestal, the light screen sensor is arranged on the left and right sides of the guide support, the hoisting mechanism and the rigid pedestal are connected through a support member therebetween, a protective sleeve sleeves the rigid pedestal, at least one moisture-content sensor bracket is fixedly arranged on the inner top face of the protective sleeve, the number of the moisture-content sensor brackets is identical to that of moisture-content sensors, and the moisture-content sensors are fixedly arranged on the moisture-content sensor brackets. The device is used for wood intensity grading.

Description

technical field [0001] The invention relates to a device for grading the strength of wood. Background technique [0002] At present, domestic wood structure and wood product suppliers and manufacturers all use manual visual grading method when grading the strength of dimension lumber and glued wood laminates. The strength of wood is discrete, the grading is not accurate, and the speed of workers grading the strength is very slow. This speed sometimes even becomes a bottleneck restricting the processing capacity of the production line, seriously affecting the production speed. Contents of the invention [0003] The object of the present invention is to provide a device for grading the strength of wood. The device adopts photoelectric measurement means and uses non-destructive testing technology to measure the elastic modulus of wood to carry out strength grading for wood. The equipment has a high level of automation and can be applied to different The specification lumber ...
