Wood moisture content detection device in high-frequency vacuum wood drying process

Abstract

The invention discloses a wood moisture content detection device in a high-frequency vacuum wood drying process. The wood moisture content detection device comprises a fixed base, and two vertical plates which are vertically arranged are fixedly connected to the upper end of the fixed base. According to the wood moisture content detection device, a classification mechanism and a second driving mechanism are arranged, so that a weighing sensor is used for detecting the weight of wood, when the weight is larger than a specified threshold value, the weighing sensor drives an electric push rod topush the wood containing moisture on a first conveying belt to the upper end of an L-shaped plate, the wood is clamped by a clamping plate and meanwhile is conveyed to a second conveying belt, so thatthe wood containing the moisture and wood without the moisture are automatically classified, and the working efficiency is improved; and a detection mechanism is arranged, so that the wood containingthe moisture is conveyed into high-frequency vacuum drying equipment through the second conveying belt, and the circumstances that woods are mixed up, and the wood without the moisture also enters the high-frequency vacuum drying equipment are avoided.

Description

technical field [0001] The invention relates to the technical field of wood detection, in particular to a wood moisture detection device in a high-frequency vacuum wood drying process. Background technique [0002] According to different properties and characteristics of wood, people use them in different ways. Wood moisture content is one of the indicators selected for wood drying benchmarks, and it is also an evaluation standard for wood drying quality in different drying stages. Therefore, real-time and online automatic detection of wood moisture content is an important aspect of the wood drying process. [0003] In the prior art, the resistance method or weighing method is often used to detect the moisture content of wood, but the resistance method is not suitable for high-frequency vacuum drying due to the interference of the magnetic field when it is used, and the latter requires Manually transport the wood to the weighbridge, weigh the weight and then calculate.

[0003] In the prior art, the resistance method or weighing method is often used to detect the moisture content of wood, but the resistance method is not suitable for high-frequency vacuum drying due to the interference of the magnetic field when it is used, and the latter requires Manually transport the wood to the weighbridge, weigh the weight and then calculate. This method has a low level of mechanization and cannot quickly and effectively classify the wood. The work efficiency is low.
