Grinding and dust removal device for wood

Abstract

The invention relates to the technical field of building materials, and discloses a grinding and dust removal device for wood. The grinding and dust removal device comprises a rotary shaft, wherein afixed rotation part is fixedly connected to the outside of the rotary shaft; a grinding part is fixedly connected to the back face of the fixed rotation part; a fixed shell is movably connected to theouter side of the fixed rotation part; an annular groove is formed in the fixed shell; and limiting sliding blocks are movably connected to the top and the left side of the fixed rotation part. According to the grinding and dust removal device for the wood disclosed by the invention, a piston is driven through the fixed rotation part so as to be rotated, and then through cooperative application of an electromagnet and a magnetic block, when the fixed rotation part is rotated, the limiting sliding blocks contact with a movable contact point so as to drive the piston to be rotated, and a dielectric plate can gradually increase relative areas of a positive plate and a negative plate, and thus, the voltage of a circuit is gradually increased, and the magnetism of the electromagnet is gradually increased, so that the aim of controlling the magnetic block to stretch an air bag so as to absorb the gas is fulfilled, and a compressed spring plays a role in compressing the air bag, and thus, the effect of automatic dust absorption can be realized.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a wood grinding and dust removal device. Background technique [0002] Building materials are a general term for materials used in civil engineering and construction engineering. They can be divided into structural materials, decorative materials and some special materials. Structural materials include wood, stone, cement, composite materials, etc. Nowadays, wood plays a great role in human life. According to the purpose of wood processing and polishing, debris is prone to appear, causing dust to fly up and affecting the visual distance of processing. [0003] When grinding wood, it is easy to grind a lot of debris. If the debris is not disposed of in time, it will easily cause dust to fly, which will affect the sight of the operator and reduce the efficiency of the grinding work. Excessive debris will accumulate on the processing surface, which will affect Workers ju...
