Abstract:
1. An integrated supplying apparatus for gas and sizing, wherein comprising: a sizing barrel provided with at least one gas inlet and at least one outlet for gas and sizing; wherein the sizing barrel is loaded with sizing; a gas supply unit comprising an air compressor; a switching unit comprising a valve seat and a rotary component; the valve seat is provided with a first through hole, a second through hole, a third through hole and a fourth through hole; it is also provided with a first channel and a second channel that are not interconnected; wherein the first through hole is connected to the first channel and further connected with a gas outlet of the air compressor, the second through hole is connected to the second channel and further connected with a filling nozzle, the third through hole is connected with the gas inlet of the sizing barrel and the fourth through hole is connected with the outlet for gas and sizing of the sizing barrel; the rotary component has a third channel and a fourth channel that are not interconnected; the rotary component is flexibly combined with the valve seat so that it can rotate with respect to the valve seat and its third channel is maintained to be connected to the first channel constantly; when the rotary component is located in a first position relative to the valve seat, the third channel is connected to the second channel so as to make the gas from the first through hole be output via the second through hole directly; when the rotary component is located in a second position relative to the valve seat, the third channel is connected to the third through hole instead of the second channel, and the fourth channel is connected to the fourth through hole, in which case the gas from the first through hole is finally input into the sizing barrel by passing through the third through hole, so that the sizing inside the sizing barrel is output via the fourth and second through holes under the action of gas pressure.
