Description

Technical Field

[0001] The utility model relates to the technical field of plate surface carving, in particular to a packaging plate surface carving processing center. Background Art

[0002] The surface engraving of packaging boards is to use an engraving processing center to engrave the relevant information of the packaging products on the surface of the board. Using an engraving processing center to engrave information on the surface of the packaging board can avoid the loss of product information and help improve the retention effect of packaging product information.

[0003] When the engraving processing center is engraving on the surface of the board, a large amount of sawdust will be generated. The traditional engraving processing center installs a vacuum duct on the side of the engraving head, and uses suction to suck the sawdust into the duct and collect it centrally. However, some sawdust will adhere to the grooves carved by the engraving head. The suction force generated by the vacuum duct is not enough to suck away the sawdust adhered to the grooves, and the sawdust cleaning effect is not good. Therefore, after the engraving processing on the surface of the packaging board is completed, the staff needs to continue to clean the sawdust on the surface of the board for a second time, which will affect the efficiency of the board engraving processing.

[0055] When the engraving head 21 is engraving the plate, the corresponding motor device is used to drive the turntable box 5 to rotate, and the corresponding motor device is used to drive the conical disk 9 to rotate.
