1. Filling principle of worm gear flowmeter can filling machine

The can enters the filling machine through the can inlet star wheel, reaches the predetermined center of the can table, and then the filling valve descends along the supporting cam to align the can and pre press and seal it. The sealing pressure is generated by a cylinder, in addition to the weight of the centering cover itself. The pressure inside the cylinder can be adjusted by the pressure reducing valve on the pneumatic control cabinet. The pressure is 0-40KPa (0-0.04MPa), and the magnitude of the pressure depends on the material of the hidden can. At the same time as opening the vacuum channel, the back pressure gas in the filling cylinder rushes into the can and flows into the vacuum channel. Vacuum pumping is used to implement CO2 flushing procedures to remove air from the tank. Through this process, the oxygen addition to the material during filling is minimized, and negative pressure is not generated in the tank. Therefore, even aluminum tanks with very thin walls can be flushed with CO2. For non vacuum filling, CO2 gas from the original vacuum channel can be directly used to flush the tank. After the vacuum valve is closed, equal pressure is established between the tank and the cylinder. The liquid valve is opened by a spring, and filling begins. The material flows down the tank wall through three inlet tanks, and the gas inside the tank returns to the filling cylinder through the gas valve. By changing the length of the return pipe, the height of the filling liquid level can be altered. When the liquid level of the material reaches the return pipe, the return gas is blocked, filling stops, and an overpressure is generated in the upper g

as part of the tank to prevent the material from continuing to flow down. Pull the fork to close the air valve and liquid valve, and exhaust through the exhaust valve to balance the pressure in the tank with atmospheric pressure. The exhaust channel is away from the liquid level to prevent liquid from being carried out during exhaust. During the exhaust period, the gas at the top of the tank expands, and the material in the return pipe falls back into the tank, emptying the return pipe. At the moment of releasing the congratulatory jar, the centering cover is lifted under the action of the cam, and under the action of the inner and outer protective plates, the jar leaves the jar platform and enters the jar conveyor chain of the capping machine, and is sent to the capping machine. If the liquid level in the cylinder is not stable, insufficient filling or foaming may occur during filling. Therefore, it is important to control the liquid level in the cylinder stably for normal filling. The entire liquid level control device consists of a reed switch type float liquid level sensor, a digital regulator, an eccentric rotary valve (including a valve positioner), etc. The liquid level in the cylinder is measured by a reed tube float level sensor 1 and converted into a 4-20mA current signal, which is then passed through a mercury rotary joint 2. Sent to digital regulator 3, after PID regulation, the output signal is sent to the electrical valve positioner of main inlet valve 4 to control the opening of the main inlet valve and achieve the purpose of controlling the liquid level of the filling cylinder. The liquid level in the filling cylinder can be set as needed on the digital regulator, and the entire liquid level control devic
