Can the granular filling machine accurately control the amount of material filled each time?

Granular filling machines can accurately control the amount of material filled each time, usually achieved through high-precision measuring systems. The following are several methods and technical points for precise control of filling volume:
1. Electronic measurement system
Working principle: Using an electronic weighing device, the weight of each filling is monitored in real-time through a weighing sensor. The weighing system is connected to the control system, which can make precise adjustments to the materials filled each time, ensuring the accuracy of the packaging.
Advantages: High precision, error range can be controlled within a few grams, suitable for industries with high granular size requirements.
2. Vibration feeding control
Working principle: Use a vibration feeding device to feed granular materials into the filling container, and control the flow rate of the materials by adjusting the vibration frequency and intensity. The vibration speed can be synchronized with the measuring system to ensure that the amount of material filled each time is consistent.
Advantages: Suitable for lightweight and uniform granular materials, it can accurately adjust the filling amount and has high adaptability.
3. Spiral feeding control
Working principle: Adopting a spiral conveying system, the feeding amount of granular materials is precisely controlled by adjusting the speed of the spiral or the stepping system. Every time the screw rotates, the material conveyed is controlled according to the set amount.
Advantages: Suitable for materials with relatively uniform granular shape and size, it can ensure high filling accuracy to a certain extent.
4. Pneumatic valve control
Working principle: granular filling machines often use pneumatic valves to control the feeding speed and flow rate. The opening and closing degree and opening time of pneumatic valves are precisely controlled to ensure the flow rate and filling volume of materials.
Advantages: This method is commonly used in situations where the filling speed is fast, while also maintaining good accuracy.
5. Quantitative control and automatic correction function
Working principle: Modern granule filling machines are usually equipped with automatic correction functions. Once a deviation is detected in each filling volume, the system will automatically adjust it. For example, if the actual filling volume is lower than the set value, the system will supplement by adjusting the speed of the spiral feeding or vibration device.
Advantages: It can avoid errors caused by external factors such as material viscosity, temperature changes, etc., and ensure the stability of filling volume.
6. Programmable Control System (PLC)
Working principle: The granule filling machine adopts a PLC control system, which can perform precise program programming to achieve precise control of filling volume, speed, time, etc. By adjusting the set values in the PLC, precise quantities can be achieved for each filling.
Advantages: Highly automated, capable of storing multiple set parameters and quickly adjusting according to different materials and requirements.
7. Adjustment of Material Characteristics
Working principle: The physical characteristics such as granular shape, size, and hardness directly affect the accuracy of filling. The filling machine can be specially adjusted according to the different characteristics of the material. For example, for materials that are prone to adhesion or fragility, filling machines can set special feeding speeds or control strategies.
Advantages: This intelligent adjustment enables the filling machine to adapt to a wider range of granular materials and improve overall accuracy.
8. Multi head filling system
Working principle: Multiple filling heads are used to work simultaneously, reducing the burden and errors during each filling process, and ensuring accurate overall filling volume through multiple allocations. The measuring system of each filling head is independently controlled, so even if one filling head has a problem, it will not affect the filling accuracy of other heads.
Advantages: It can improve production efficiency and maintain precise filling volume every time.
