The invention discloses a label taking machine which comprises an installation plate, a rotating device, label taking shafts, air seal sleeve sets, bearing seats and a synchronous device. The rotatingdevice and the bear seats are fixed to the installation plate. The installation plate and the label taking shafts vertically and rotationally penetrate the installation plate. The label taking shaftsare sleeved with the bearing seats. The upper ends of the label taking shafts are in transmission connection with the rotating device through the synchronous device. Suckers are arranged at the lowerends of the label taking shafts, and the air seat sleeve sets are arranged between the label taking shafts and the bearing seats. Each air seal sleeve set comprises an air seal inner sleeve and an air seal outer sleeve. The air seal inner sleeves are arranged outside the label taking shafts in a sleeving manner, and the air seal inner sleeves are sleeved with the air seal outer sleeves. The labeltaking machine has the beneficial effects that higher durability is achieved, and the gas tightness is good.
