Description

Wood board polishing equipment
Technical Field
The invention belongs to the technical field of wood processing, and particularly relates to wood board polishing equipment.
Background
Because the surface of the wood board has the defects of burrs and the like, the wood board needs to be polished before being used for processing other products, otherwise, the surface of the wood board is very rough and does not meet the use requirement. When the wood board is polished, workers firstly adjust the height position of a polishing wheel of the polishing machine according to the height of the wood board, so that the wood board can smoothly pass through the lower part of the polishing wheel. Then the worker holds the wood by hand and drives the wood to move under the grinding wheel in a reciprocating manner, so that the polishing processing of the wood board is realized. By adopting the processing mode, the processing efficiency is lower, and when workers push the wood plate to do reciprocating motion under the polishing wheel, the workers easily touch the polishing wheel to be injured, so that the safety is also to be further improved.
