A vacuum chuck capable of preventing a full material bag from deforming comprises a vacuum cavity 1, the upper end of the vacuum cavity 1 is communicated with a vacuum source, a sealing rubber ring 2 is arranged on the periphery of the lower end of the vacuum cavity 1, the hardness of the sealing rubber ring 2 is medium, the cross section of the sealing rubber ring 2 is rectangular, a pressing plate 3 is further arranged in the vacuum cavity 1, and the pressing plate 3 is connected with the vacuum cavity 1. The pressing plate 3 is provided with a plurality of through holes 5 arranged at intervals, the lower surface of the pressing plate 3 is further provided with a plurality of jacking columns 4 arranged at intervals, the through holes 5 and the jacking columns 4 are arranged in a staggered mode, and the lower end faces of the jacking columns 4 do not exceed the lower end face of the sealing rubber ring 2. The device can prevent a material bag below the vacuum chuck from protruding and deforming, and can be used for sucking and hanging a double-layer packaging material bag with separated inner and outer packaging bags.
