What is a pneumatic liquid filling machine?
A pneumatic filling machine uses compressed air to fill liquid or cream, widely used in medicine, chemicals, food industries. This machine is the ideal paste and viscosity fluid filling equipment.
In modern industrial production, the application of filling machines has become crucial. Various filling machines are available in the market, including manual, semi-automatic, and fully automatic models. The semi-automatic vertical pneumatic machine has won the favor of many enterprises due to its unique advantages and characteristics. Today, let’s discuss semi-automatic vertical pneumatic filling machines and why they are so popular.
Working principle of pneumatic filling machine
Choosing suitable filling equipment is necessary for environments with high explosion-proof requirements in modern industrial production. The fully pneumatic semi-automatic piston filling machine has become the ideal choice for such environments.
This piston filler replaces traditional electrical control circuits with pneumatic components, ensuring safety. It mainly relies on the cylinder’s forward and backward motion to drive the piston in the filling cylinder to move back and forth.
When the cylinder moves forward, it pulls the piston backward, creating negative pressure in the front chamber of the material cylinder. And push the material in the feeding hopper into the feeding hose by atmospheric pressure. It enters the material cylinder through the three-way valve for feeding and discharging.
When the cylinder moves backward, it drives the piston forward, squeezing the material. The material enters the discharge hose through the discharge one-way valve. Finally, it enters the empty bottle through the filling head, completing one filling cycle.
This piston filling method ensures high filling accuracy and stability for each filling, whether for regular or irregular containers.
Characteristics of the Fully Pneumatic Filling Machine:
1. Controlled by compressed air, This filling machinery is suitable for explosion-proof environments. This design avoids potential safety hazards associated with electrical control.
2. The equipment operates without generating static electricity or numbness. It eliminates the need for grounding and enhances safety during use.
3. The filling accuracy is high because of pneumatic control and hard positioning.
4. The piston will automatically go back to the initial position when close the pneumatic switch. The machine will stop the filling process immediately. It can enhance the flexibility and safety of the equipment operation.
5. The filling system has manual mode and automatic filling mode.
When the machine is in the “automatic” mode, the machine will automatically fill materials according to the setup speed. When the machine is in “manual” mode, the operator needs to step on the pedal to initiate filling. The machine will change to automatic mode if keep stamping on the pedal switch.
Application range:
Semi-automatic pneumatic filling machines are widely used in various industries, including but not limited to:
Food and Beverage Industry: Used for filling water, fruit juice, oil, sauces, and other liquid food products.
Cosmetics and Personal Care Products Industry: Used for filling shampoo, shower gel, skincare products, and various liquid cosmetics.
Chemical Industry: Used for filling cleaners, lubricants, pigments, liquid fertilizers, and various chemical products.
Medical Industry: Used for filling oral liquids, liquid medications, medical alcohol, and other medical products.
In short, pneumatic filling machines are vital in modern industry. They offer essential support to enterprises because of their efficiency, precision, flexibility, and reliability.
