Working Principle
The grease filling machine with servo rotor pump rotates the rotor of the rotor pump driven by the servo motor, thus realizing the extraction and transportation of grease. During the filling process, the control system precisely controls the rotation speed and running time of the servo motor according to the preset filling volume and filling speed to ensure that the amount of grease filled each time is accurate without error.
Structural Composition
Electrical Part: It includes power supply, key control, touch instrument, sensor, servo controller, servo motor, etc., which are used to control the operation and parameter setting of the entire filling machine.
Oil Extraction System: It consists of oil inlet pipeline, cam rotor pump, oil outlet pipeline, anti-drip and anti-leakage nozzle, etc., and is responsible for the extraction, transportation of grease and prevention of dripping and leakage.
Frame and Shell: They are mostly made of high-quality stainless steel, with an elegant appearance and meeting the requirements of food hygiene. The pipelines in contact with materials are generally made of 304# stainless steel and plastic pipes, enabling CIP cleaning.
Filling System: It includes filling heads, anti-drip and anti-leakage devices, lifting and filling devices, etc., ensuring that the grease is accurately filled into containers and preventing dripping and stringing phenomena during the filling process.
Features and Advantages
High-Precision Filling: Adopting servo technology and an accurate metering system, it has a high filling accuracy, generally reaching ±0.5% or even higher, which can effectively ensure the quality and consistency of products.
Wide Applicability: It is suitable for filling various greases, including lubricating oil, edible oil, butter, petrolatum, etc., and can achieve good filling effects for greases with different viscosities. It can also be applied in multiple industries such as daily chemicals, medicine, food, beverages, and chemical engineering.
Flexible Adjustability: Both the filling volume and filling speed can be adjusted arbitrarily according to needs, which can meet the requirements of different production scales and production processes and improve production efficiency.
Energy Saving and Stability: The delicate servo motor is more energy-efficient while ensuring sufficient power, and it operates stably and reliably with a long service life, which can effectively reduce production costs and maintenance costs.
High Degree of Automation: Equipped with an advanced control system, such as PLC combined with human-machine interface (touch screen) control, the operation is simple and intuitive. It can automatically complete processes such as cap removal, vacuum extraction, quantitative filling, and cap pressing at the same station, reducing manual intervention and improving production efficiency and product quality.
Technical Parameters
Filling Accuracy: It is usually between ±0.5% and ±1%. Some high-precision filling machines can reach about ±0.2%.
Filling Volume Range: According to different models and specifications, the filling volume generally ranges from dozens of milliliters to hundreds of liters. For example, the filling volume of common small filling machines is 100 milliliters - 5 liters, and that of large filling machines can reach 200 liters or more.
Filling Speed: Affected by factors such as filling volume and grease viscosity, it is generally in the range of 10 - 100 barrels/hour or 100 - 500 bottles/hour. There are also some high-speed filling machines that can achieve higher filling speeds.
Power Requirement: Most of them are three-phase alternating current 380V 50Hz. Some small filling machines can also use 220V power supply.
Power: The power varies depending on the equipment model and configuration. The power of small filling machines is generally 1 - 3kW, and that of large filling machines may be above 5kW.
