Small liquid packaging machine package quantity control device

The utility model relates to a small-sized liquid packaging machine packaging quantity control device, which mainly comprises a first time delay driver, a second time delay driver, a liquid level detection sensor, a liquid leakage detection sensor, a driver and an automatic stop relay. The signal input ends of the first and second time-delay drivers and drivers are connected to the parking position signal of the brake cam of the packaging machine; the signal output end of the first time delay driver is connected in series with the power supply circuit of the edge sealing motor and the sealing motor through the switch and the control seal. The start of the edge motor and the sealing motor; the signal input terminal of the second time delay driver is also connected with the signal output end of the liquid level and the leakage detection sensor; the signal output end is connected with the water pump control end; and the signal output end of the driver is used The packaging machine that controls the sealing motor and the sealing motor stops is automatically connected to the relay. The utility model controls the rotation time of the edge sealing motor or the sealing motor through the first and the second time delay drivers, and the time of injecting the liquid medicine by the water pump; thereby changing the packaging volume of the packaging bag.
