This machine is especially suitable for the filling and sealing of cans in the beer industry. The secondary exhaust can be carried out in the filling valve to minimize the oxygen increase in the beer filling process.
Filling and can sealing for the overall design, using the principle of isobaric filling, pot through into the pot of the star wheel into the filling machine, reach the tank after booking center, and then filling valve along the bearing CAM down, place the pot on and preloading seal, seal pressure besides centering to cover its own weight, is produced by a cylinder pressure, the pressure inside the cylinder according to the material of POTS can be used on the control panel, to adjust the pressure reducing valve of the pressure of 0 ~ 40 KP (0 ~ 0.04 MPa), at the same time on the open air and the back pressure valve, in the low pressure ring opening at the same time, the back pressure in cylinder filling gas into the tank, and flow into the low pressure ring channel.
This process is used to implement the CO2 flushing procedure to remove the air in the tank. Through this procedure, the oxygen increase is reduced to the minimum during the filling process. No negative pressure is generated in the tank.
After the prefill valve is closed, equal pressure is established between the tank and the cylinder. The liquid valve is opened by the spring under the action of the operating valve stem, and then the filling begins. The material flows down the tank wall through three liquid inlets.
When the liquid level of the material reaches the return pipe, the filling is stopped by blocking the return gas, and an overpressure is generated in the upper part of the tank, thus preventing the material from continuing to flow down.
Material fork will be pulled out of the air valve, liquid valve closed, through the exhaust valve, exhaust so that the pressure in the tank and atmospheric pressure balance, exhaust away from the liquid level, so as to prevent the exhaust out of the liquid.
During the exhaust, the top gas in the tank expands, and the materials in the return pipe fall back into the tank to empty the return pipe.
At the moment of the pot, the centering cover is lifted under the action of the CAM. Under the action of the inner and outer guard plate, the pot leaves the pot platform and enters the canister transport chain of the capping machine and is sent to the capping machine.
This machine is the main electrical components adopt Siemens PLC, omron high-quality configuration, such as the proximity switch by senior electrical engineer design into the most reasonable configuration forms, the whole production rate can be in accordance with the requirements set by the touch screen, all common fault automatic alarm, and gives the corresponding failure reason, according to the severity of the fault, the PLC automatically determine whether the host can continue to run or stop.
