The construction structure material of the machine is 304 stainless steel, accompanied by a material quality certificate. Pistons and dosing heads are meticulously crafted from 316L stainless steel, with corresponding material certificates. The piston gaskets are composed of non-corrosive material, carefully selected based on the nature of the liquid products.
In terms of robustness, the electrical installation and CPU are designed to be waterproof, ensuring durability and reliability. The pneumatic system is equipped with SMC or Festo as the main parts, renowned for their quality and performance.
The Human Machine Interface (HMI) is strategically positioned on the dosed product release side for user convenience. The machine is equipped with a minimum of three emergency stop buttons – one near the touch screen, another near the empty product insertion side, and one located at the back of the machine.
When it comes to components, the CPU and HMI boast brands from Europe, Japan, and China, ensuring a combination of advanced technology and reliability. Electrical components are sourced from Schneider, a trusted name in the industry.
The electric installation is meticulously organized, with each cable identified and documented through a single-line electrical diagram covering the entire system. Ball bearings and seals are sourced from SKF and other top-level Chinese brands, ensuring optimal performance.
The machine features servo-driven diving filling heads for precise dosing of liquids. Pneumatic shut-off and anti-drip filling nozzles enhance the accuracy of the dosing process. As a standard feature, a drip tray is incorporated, further ensuring a clean and efficient operation.
The operation of an automatic piston filling machine, such as the ones provided by Shanghai Npack, is both intuitive and efficient. This type of filling machine shares common features with others, incorporating essential components like pistons and advanced control systems including PLC (Programmable Logic Controller), frequency converters, and motors.
At the core of the piston filling machine is the volumetric filling mechanism, where precision is key. The pivotal components in this process are the piston and cylinder. The system operates on a straightforward stroke movement principle, facilitating the accurate measurement and dispensing of liquids into containers.
The operation begins with the pulling of the piston, allowing the liquid to enter the cylinder. Subsequently, the piston is pushed, transferring the precisely measured liquid into bottles. This systematic pull-and-push movement is reminiscent of a syringe, ensuring a reliable and efficient liquid filling process.
Here are some of the primary application fields for piston filling machines:
- Food and Beverage: These machines are ideal for filling viscous food products such as sauces, jams, honey, and condiments. They can also handle more fluid items like water, juices, and other beverages precisely without causing spillage or foam.
- Cosmetics and Personal Care: In the cosmetic industry, piston fillers are used for accurately dispensing creams, lotions, gels, and other skincare products. They can manage products with a wide range of consistencies, from watery toners to thick body butters.
- Pharmaceuticals: Piston filling machines are critical in the pharmaceutical sector for filling syrups, creams, pastes, and other medicinal preparations. The accuracy and hygiene provided by piston fillers are essential for adhering to stringent industry regulations.
- Chemicals: For chemical products like detergents, solvents, and lubricants, piston fillers can effectively handle both harsh and delicate chemical viscosities while ensuring that containers are filled to the precise level required.
- Household Products: These machines are also used for filling household goods such as cleaning agents, dishwashing liquids, and other household chemicals.
- Paints and Coatings: Piston filling technology can be utilized for filling various types of paints and coatings, which often require handling of thick, viscous materials.
