Do You Know How To Buy A Paste And Liquid Filling Machine?

In modern industrial production, filling machines, as important equipment in the packaging industry, are widely used in food, medicine, chemical industry, daily chemicals and other fields. Its main function is to accurately fill liquids, pastes or granular materials into various containers to ensure product quality and packaging standardization. With the continuous advancement of technology, the types and functions of filling machines are becoming increasingly rich, and can meet the needs of different industries and material characteristics.

Ⅰ. Piston filling machine

1. Working principle

The piston filling machine realizes quantitative filling of materials through the reciprocating motion of the piston. Its working process includes two stages: suction and filling. In the suction stage, the piston moves upward to form a negative pressure, sucking the material from the storage tank into the piston cylinder; in the filling stage, the piston moves downward to press the material from the piston cylinder into the container to be filled. The filling volume can be controlled by adjusting the stroke of the piston, thereby achieving high-precision filling.

2. Application areas

The piston filling machine is suitable for medium and high viscosity liquids and paste materials, such as toothpaste, ointment, cosmetic paste, ketchup, chili sauce, etc. Its advantages are high filling accuracy and strong adaptability, especially suitable for filling small and medium doses and high viscosity materials.

3. Advantages

• High precision: The piston filling machine can achieve high-precision filling to ensure consistent filling volume for each container.

• Wide range of application: It can handle a variety of materials from low viscosity liquids to high viscosity pastes.

• Economical: Compared with other complex equipment, the initial investment cost of the piston filling machine is lower, which is suitable for small and medium-scale production.

• Simple operation: The equipment structure is simple and easy to operate and maintain.

Ⅱ. Magnetic pump filling machine

1. Working principle

The magnetic pump filling machine uses magnetic force to drive the rotation of the pump, and the liquid is transported from the liquid storage tank to the filling head through the pump's impeller. Its working principle is based on magnetic coupling, and the magnetic force transmission of the outer magnetic rotor and the inner magnetic rotor drives the pump shaft to rotate, thereby realizing the delivery of liquid. This design avoids the mechanical sealing problem of traditional pumps and reduces the risk of leakage.

2. Application field

The magnetic pump filling machine is suitable for low-viscosity and medium-viscosity liquids, such as potions, perfumes, edible oils, lubricants, etc. It is characterized by compact structure, smooth operation, and high filling accuracy, especially suitable for industries with high requirements for hygiene and safety, such as medicine and food.

3. Advantages

• Leak-free design: The magnetic coupling design of the magnetic pump avoids the mechanical sealing problem of traditional pumps and reduces the risk of leakage.

• High-precision filling: It can achieve accurate liquid metering and ensure the consistency of filling volume.

• Strong adaptability: It can handle a variety of liquid materials, especially suitable for industries with high requirements for hygiene and safety.

• Smooth operation: compact structure, stable operation, suitable for continuous production.

Ⅲ. Peristaltic pump filling machine

1. Working principle

The peristaltic pump filling machine uses the roller to squeeze the hose to move the liquid in the tube, thereby achieving filling. Its working process is: when the roller rolls along the hose, the liquid in the hose is gradually pushed forward until it reaches the filling head and is injected into the container. The filling volume can be controlled by adjusting the speed of the roller and the inner diameter of the hose.

2. Application areas

The peristaltic pump filling machine is suitable for low-viscosity and medium-viscosity liquids, such as shampoo, conditioner, potion, juice, etc. Its advantages are simple operation, convenient maintenance, and low shear force on the material, which is suitable for filling sensitive liquids.

3. Advantages

• High-precision control: The peristaltic pump filling machine can achieve high-precision liquid metering and is suitable for refined filling needs.

• Pollution-free design: The liquid only contacts the hose, avoiding contact with other parts in the pump, ensuring the hygiene of the filling process.

• Low maintenance cost: simple structure, stable operation, and easy maintenance.

• Strong adaptability: It can handle a variety of liquid materials, especially suitable for sensitive liquids.

IV. Rotor pump filling machine

1. Working principle

The rotor pump filling machine relies on the rotational motion of the rotor to suck the liquid from the feed port and discharge it from the discharge port. Its working principle is based on volumetric filling, and the material is accurately delivered to the filling head through the chamber of the rotor. The filling volume can be controlled by adjusting the speed of the rotor and the volume of the chamber.

2. Application fields

Rotor pump filling machines are suitable for high-viscosity liquids and pastes, such as glue, sealant, lubricating oil, syrup, etc. It is characterized by high filling accuracy and strong adaptability, especially suitable for filling large doses and high-viscosity materials.

3. Advantages

• High-precision filling: It can achieve high-precision filling to ensure consistent filling volume for each container.

• Wide adaptability: It can handle high-viscosity materials and is suitable for a variety of production needs.

• High degree of automation: The equipment is controlled by PLC, which is simple to operate and suitable for large-scale production.

• Strong durability: Made of high-quality materials, the equipment has a long life and low maintenance cost.

V. Summary

Different types of liquid and paste filling machines are suitable for materials of different viscosities and properties according to their working principles and structural characteristics. Piston filling machines are suitable for high-viscosity pastes, magnetic pump filling machines are suitable for low-viscosity liquids, peristaltic pump filling machines are suitable for sensitive liquids, and rotor pump filling machines are suitable for high-viscosity liquids. Therefore, you need to consider factors such as material properties, filling accuracy requirements, production efficiency, and hygiene standards when choosing a suitable paste and liquid filling machine.
