Vacuum adsorber
InactiveCN101722483AImprove breathabilityAdsorption immobilizationWork holdersPulp and paper industryVacuum pump
The invention relates to a vacuum adsorber belonging to the technical field of an engraving machine. The vacuum adsorber of the invention comprises a workbench, wherein an adsorbing surface is arranged at the upper side of the workbench, and a ventilating plate is laid on the adsorbing surface of the workbench. In the engraving process, a workpiece is laid at the upper side of the ventilating plate; when a vacuum pump works, the ventilating plate is tightly adsorbed on the adsorbing surface of the workbench; and because the ventilating plate has better air permeability, the workpiece is also tightly adsorbed on the ventilating plate, thereby realizing the purpose of adsorbing and fixing the workpiece. Meanwhile, because the workpiece and the surface of the workbench are separated by the ventilating plate, the falling scraps generated by engraving the workpiece can not enter adsorbing holes, thereby ensuring the smooth operation of the engraving process.
