Abstract
The present invention discloses an integrated supplying apparatus for gas and sizing. It comprises a sizing barrel, a gas supply unit and a switching unit. The sizing barrel and the gas supply unit are both connected with the switching unit. When the switching unit is fixed in a first state by a safety cover, the gas supply unit can only output high pressure gas through the switching unit. When the switching unit is converted into a second state by releasing the safety cover, the gas supply unit in turn outputs some high pressure air into the sizing barrel through the switching unit, so that the sizing inside the sizing barrel is output under the action of the gas pressure and the gas inside the sizing barrel is then output when completing the output of the sizing.
