AI Technical Summary
Existing gravity-flow filling machines suffer from insufficient pressure and low flow rate when the water level in the container tank is too low, resulting in filling weight deviation. Upgrading to container-type or weighing-type filling machines will increase production and time costs.
By adding structures such as water pumps, transition tanks, reflux holes, and isolation plates, a constant pressure liquid level in the filling tank is maintained to ensure filling stability. Pneumatic valves are used to control the liquid levels in the raw material tank, transition tank, and filling tank. The reflux hole is used to handle raw materials that overflow above the liquid level, so that liquid is supplied when the level is low and stopped when the level is high.
By adding only a few structural elements to the existing device, a stable liquid level and hydraulic pressure in the filling tank were achieved, avoiding weight deviations and saving costs and time.
