Major characteristics
1.This automatic weighing filling machine is suitable for liquid filling between10kg and 50kg. It is characterized by large productivity, high automation,weighing filling and high precision。
2.This machine is controlled by computer (PLC) and touch screen control panel,filling specifications of whole 10 heads can easily be changed by altering parameter on touch panel . Filling volume of each filling head can also be adjusted respectively .
3.The filling process consists of fast filling and slow filling, at the beginning of filling, the fast filling valve and slow filling valve both open to achieve fast filling, when the filling volume reach to the set value, the fast filling valve will be closed to achieve slow filling, to guarantee the filling accuracy, when the filling value reach to the target value, the slow filling valve will close automatically.the filling hopper is designed by pressure type, to increase the filling speed; adopts screw type feeding bottle, greatly shortened the time of bottle push in and out.
4.Adopt three-row filling mode, with front row as bottle inlet, middle row as filling by weighing ,and rear row as bottle outlet, greatly shortening the time of filling process .
Working Principle
The operation follows a fast, accurate, typically two-stage filling process:
Container Positioning: An empty square barrel is conveyed into the filling station. A clamping mechanism secures it in place, and the filling nozzle lowers to create a seal.
Gross Weight Taring: The load cell measures the weight of the empty barrel and automatically sets it to zero (tare).
Fast-Fill (Bulk) Stage: The feeding system (e.g., screw auger) operates at high speed, dispensing approximately 90-95% of the target product weight into the barrel.
Dribble-Fill (Topping) Stage: The system automatically switches to a slow, precise feeding mode to add the remaining 5-10%. This prevents overfilling and ensures high accuracy.
Weight Verification & Nozzle Retraction: The final weight is checked against the target. If it is within the preset tolerance, the filling nozzle retracts, and the container clamp releases.
Container Discharge: The filled square barrel is conveyed out of the station, and the next empty barrel moves in, repeating the cycle.
Features and Advantages
High Accuracy: Achieves filling accuracies of up to ±0.1% to ±0.2% of the target weight, reducing product giveaway.
Adaptability to Square Barrels: Specialized nozzles and clamping systems ensure a perfect fit, minimizing dust and spillage.
Speed: Capable of high-speed operation, with cycles ranging from 4 to 10+ barrels per minute, depending on product and target weight.
Dust Containment: The closed system with a retractable nozzle is ideal for dusty, hazardous, or sensitive products.
User-Friendly: Simple operation and recipe storage on the HMI allow for quick changeovers between different products and barrel sizes.
Hygienic Design: Automatic weighing filling machine with stainless steel construction and easy-clean surfaces meet hygiene standards for food, pharma, and chemical industries.
