Description

Technical Field

[0001] The utility model relates to the technical field of wood board numerical control engraving machines, in particular to a numerical control engraving machine used for wood board processing. Background Art

[0002] Wood board processing and carving is a craft with unique characteristics and artistic value. It requires selecting suitable wood boards, such as wood with moderate hardness and beautiful texture. According to needs and creativity, draw the pattern to be carved on paper or with the help of design software, and use appropriate carving tools. After carving, use sandpaper and other tools to carefully polish the carving surface and the surrounding area to make it smooth. Paint, oil and other surface treatments are performed as needed to protect the wood and enhance its beauty. At present, in order to increase the speed of wood board carving, CNC engraving machines for wood board processing are generally used for carving. The working area of ​​existing CNC engraving machines for wood board processing is generally open, and the operator needs to place the wood board to be carved on the bottom of the carving knife by himself. During carving, the top of the CNC engraving machine for wood board processing lacks a protective structure, which makes it inconvenient to automatically complete the feeding and discharging of the wood board. Flying chips may cause certain harm to the human body during carving, which is not conducive to improving the safety during processing. Utility Model Content
