Detection apparatus for wane defect of rectangular bamboo splint

Abstract

The invention specifically relates to a detection apparatus for a wane defect of a rectangular bamboo splint and provides a simple high-efficient detection scheme for the wane defect of the rectangular bamboo splint. The detection apparatus comprises a front baffle plate and a rear baffle plate; the front baffle plate and the rear baffle plate are both provided with rectangular holes; an upper horizontal guide bar, a lower horizontal guide bar and a leftward-and-rightward guide block are fixedly arranged between the front baffle plate and the rear baffle plate; four support ears are respectively installed at four corners of the horizontal guide bars and separately hinged with detection levers; a detection roller is supported in a central groove of each detection lever via a rotating shaft, and the other end of the detection lever is provided with reel; and tightening springs and steel wire ropes of pull sensors are wound on different parts of the reels. According to the invention, whether any edge of the rectangular bamboo splint has a wane can be integrally discriminated through ingenious structure design; the detection apparatus is simple and highly efficient; and since the detection apparatus mainly employs a mechanical detection manner, the detection apparatus has the advantages of few external interference factors, more stable work performance, detection precision of 1 mm and low cost compared with a photoelectric detection manner.

Description

technical field [0001] The invention relates to bamboo chip processing and testing equipment in the agriculture and forestry industry, in particular to a rectangular bamboo chip chip edge defect detection device. Background technique [0002] my country is the most important bamboo-producing country in the world, and its bamboo resources, bamboo forest area, bamboo stock and output all rank first in the world. In addition to ecological significance, bamboo industry also has important economic and social value. There are dozens of bamboo wood-based panel products, the main products are bamboo woven plywood, bamboo plywood, bamboo laminated board, bamboo mat and bamboo curtain plywood, bamboo fiberboard and bamboo particleboard. The main products processed, it is mainly used for engineering structural materials and decorative materials. As the main semi-finished raw material of bamboo wood-based panels, bamboo chips will have different colors due to different origins and hea...
