The weighing Filling machine adopts anti-drip nozzle and vacuum suction technology to eliminate the drawbacks of dripping oil after filling, and ensure that the packaged product is not polluted by the filling residue. The intelligent double flow rate control technology is used to use large flow rate in the early filling period and small flow rate in the later filling period to ensure that the filling medium does not overflow. Equipped with the automatic protection function of the top barrel, it is used to automatically lift the gun when the filling gun is not inserted into the barrel, and the filling is not performed; Unique anti-drip device to avoid material dripping on drums and scales, affecting packaging and rollers; Two filling modes of net weight and gross weight are used to meet the filling needs of different resin types.

Automatic filling machine When the liquid level in the liquid storage tank is at the lower liquid level (lower limit value) or below, the float pressure plate is released from the mechanical valve and the pneumatic butterfly valve, and the liquid material is transported to the liquid storage tank through the feed port. As the liquid level continues to rise, the float assembly rotates in the direction of the arrow, and when the liquid level in the liquid storage tank reaches the upper liquid level (upper limit value), The mechanical valve contact and the pneumatic butterfly valve are closed to stop conveying liquid materials to the liquid storage box. The Filling system is controlled by pneumatic valve, mechanical valve and pneumatic butterfly valve. Air control valve is normally open, mechanical valve, pneumatic butterfly valve is normally closed. When the air source is opened, the air directly opens the pneumatic butterfly valve through the air control valve, and the liquid is transported to the liquid storage box through the butterfly valve. When the liquid level in the liquid storage tank reaches the set maximum, the float pressure plate presses down the mechanical valve contact to replace the mechanical valve, and the pneumatic control valve is replaced through the mechanical valve to close the pneumatic butterfly valve, and the liquid transfer to the liquid storage tank is stopped. With the filling process, the liquid level in the liquid storage box continues to drop, when the liquid level in the liquid storage box reaches the set minimum value, the pressure plate leaves the mechanical valve contact, the mechanical valve and the air control valve are reset under the action of the spring, the pneumatic butterfly valve is opened again, and the liquid is transported to the liquid storage box again through the pneumatic butterfly valve. The cycle repeats.
