The invention discloses a quick disassembling type key strip air expansion shaft. The quick disassembling type key strip air expansion shaft comprises an air expansion shaft head and a base shaft; theair expansion shaft head comprises a central spindle, a plurality of air bags, a plurality of rubber key strips, a plurality of first pressing sheets and a plurality of second pressing sheets; a plurality of strip-shaped fixing grooves are formed in the peripheral surface of the central spindle, and the rubber key strips and the air bags are inserted into the fixing grooves; the air bags correspond to the fixing grooves one to one, the first pressing sheets are in buckling connection with the fixing grooves in a one-to-one correspondence mode, and the second pressing sheets are in buckling connection with the fixing grooves in a one-to-one correspondence mode; and the first end of the base shaft is inserted into a first vent hole and detachably connected with the central spindle, and thesecond end of the base shaft is located outside the central spindle. The quick disassembling type key strip air expansion shaft has the advantages that the supporting force is uniform, a core windingdrum can not be deformed when the core winding drum is expanded, maintaining and assembling are convenient, and the production efficiency is high.
Description
technical field [0001] The invention relates to the technical field of air shafts, in particular to a quick-detachable key bar air shaft. Background technique [0002] The air shaft is a special winding and unwinding shaft, that is, the shaft whose surface can protrude after high-pressure inflation, and the shaft whose surface part retracts quickly after deflation is called the air shaft. It is a special winding and unwinding shaft, that is, the shaft whose surface can protrude after high-pressure inflation, and the shaft whose surface part retracts quickly after deflation is called an air expansion shaft. Its name is diversified, and it is also called pneumatic shaft, expansion shaft, air shaft, air shaft, air shaft, pressure shaft, air shaft, etc. The air shaft has a wide range of uses. All kinds of machines are applicable to the air shaft, even including the light metal industry. [0003] The air shaft is mainly suitable for printing equipment: drying board machine, fle...
