In the actual process of engraving the raw material plate, the raw material plate is first placed on the workbench, and the columns in the engraving machine are moved longitudinally and the engraving mechanism is moved horizontally and up and down by CNC, so that the engraving head can engrave the raw material plate on the workbench.

[0004] During operation, the engraving machine in the prior art generates a large amount of heat due to the friction between the cutter head and the wood due to the rapid rotation. If the temperature is not reduced in time, it is easy to cause damage to the cutter head and the engraved wood. In addition, during the wood engraving process in the prior art, the movement of the engraving mechanism will cause the engraving cutter head to drive the wood to move, which will affect the engraving effect. The prior art lacks a method for limiting and fixing the wood near the engraving cutter head, so improvement is needed. Utility Model Content
