Servo rotor pump powder filling machine is a kind of equipment used for powder filling material

Publication time:2025-02-22

Working Principle


  • Working Principle of the Rotor Pump: It mainly consists of a pair of synchronously rotating rotors. The rotors rotate within the pump body and transport the powder mass materials by periodically changing the volume of the pump cavity. When the rotors turn, the powder mass materials are sucked into the pump cavity. As the rotors continue to rotate, the materials are carried to the outlet and then extruded under pressure, thus achieving the transportation of the materials.

  • Principle of Servo Control: A servo motor is used to drive the rotor pump. The servo control system accurately controls the filling volume by regulating the rotational speed and rotation time of the servo motor. For example, through preset parameters, the control system can make the motor rotate a specific angle or number of turns within a specific time, ensuring that the amount of material output for each filling reaches the predetermined accurate value.

Structural Composition


  • Drive System: It includes components such as a servo motor, a speed reducer, and a drive chain. It is responsible for driving the various components of the filling machine, providing power to the rotor pump, and enabling it to rotate at a predetermined speed and in a specific manner.

  • Measurement System: Generally composed of a measuring container, a weighing sensor, etc., it is used for quantitatively measuring the powder mass materials to ensure that the amount of material in each package meets the specified requirements.

  • Filling System: It contains components such as a filling head and a filling valve, and is responsible for accurately filling the metered powder mass materials into the packaging containers.

  • Control System: Usually composed of a PLC, a touch screen, etc., it is the “brain” of the filling machine. It coordinates the work of various components, achieving functions such as automatic quantification, automatic filling, and automatic correction of measurement errors. It can also monitor the operating status of the equipment and diagnose faults.

  • Hopper: It is used to store a large amount of powder mass materials, providing a continuous supply of materials for the filling process. Generally, it has a certain capacity and structural design to ensure the smooth discharge of materials.

Characteristics


  • High - Precision Filling: It can achieve high - precision filling of powder mass materials. The measurement accuracy can be controlled within a small range, and the error is usually controllable within ±1%, meeting the requirements for the packaging weight accuracy of powder mass products.

  • Adaptability to Various Materials: It can handle powder mass materials with different viscosities and particle sizes, and has good adaptability to various powder mass materials, such as powdery materials in the form of masses like flour, starch, milk powder, and medicinal powder.

  • High Stability: The working process of the rotor pump is relatively stable. During long - term filling operations, it can maintain a stable flow rate and pressure, reducing equipment failures and filling quality problems, and improving production efficiency.

  • Easy to Operate: It is equipped with a user - friendly operation interface. Operators only need to simply set parameters, and the equipment can automatically complete a series of operations such as quantification and filling without the need for complex training or professional skills.

  • Convenient for Cleaning and Maintenance: The parts in contact with the materials are usually made of stainless steel, with a smooth surface and no sanitary dead - ends, which is convenient for cleaning and disinfection and can effectively prevent cross - contamination. At the same time, the equipment has a reasonable structural design, and each component is easy to disassemble and install, facilitating maintenance personnel to carry out daily maintenance and troubleshooting.

Application Fields


  • Food Industry: It can be used for the quantitative packaging of powder - mass - shaped foods such as milk powder, flour, starch, protein powder, and seasonings, ensuring the accuracy and hygiene of food packaging.

  • Pharmaceutical Industry: It is suitable for the filling of various powder - mass - shaped medicines such as medicinal powder and traditional Chinese medicine powder, ensuring that the dosage of the medicine packaging is accurate and meets the quality standards of pharmaceutical production.

  • Chemical Industry: It is also widely used for the packaging of chemical powder mass materials such as dyes, pigments, plastic particles, and rubber additives. It can adapt to the characteristics of different chemical materials and achieve accurate filling.
