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.
Claims7
An integrated supplying apparatus for gas and sizing, 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, a plunger and a linkage part;
- wherein, the valve seat has a plunger hole, and it also provided with a first via, a second via, a third via and a fourth via for connecting the inside and outside of the plunger hole;
- wherein the first via is connected with a gas outlet of the air compressor, the second via is connected with a filling nozzle, the third via is connected with the outlet for gas and sizing of the sizing barrel, and the fourth via is connected with the gas inlet of the sizing barrel;
- the plunger has a central hole extending axially throughout to one end of the plunger, and it has a first annular region, a second annular region and a third annular region on its outer diameter, wherein a first through hole and a second through hole are arranged in the plunger wall of the first and third annular regions respectively, and both ends of the respective first, second and third annular regions are provided with a leakage stop ring respectively;
- the plunger is combined to the plunger hole of the valve seat so that the plunger can move axially between a first stroke and a second stroke that are in the opposite direction relative to each other in the plunger hole;
- when the plunger has moved to the first stroke, the first via is connected to the second via through the second annular region, in which case the gas is directly output by the second via;
- when the plunger has moved to the second stroke, the first via is connected to the first through hole through the first annular region, the third via is connected to the second via through the second annular region, and the fourth via is connected to the second through hole through the third annular region, in which case the gas is eventually input into the sizing barrel through the fourth via, so that the sizing inside the sizing barrel is output by virtue of the third and second vias under the action of gas pressure;
- the linkage part is connected with the plunger so as to make the plunger move between the first and second stroke.
