The vertical packaging machine with servo rotor pump is an automatic packaging equipment used for packaging various materials such as fluids, semi - fluids, and pastes. The following is a detailed introduction:
1. **Working Principle**:
- **Material Supply**: The material to be packaged is first transported to the servo rotor pump. The rotor pump forms a closed working chamber within the pump casing through the rotating rotor, sucking the material from the inlet and pushing it to the outlet, thus achieving stable material transportation.
- **Metering and Filling**: The servo motor precisely controls the rotation speed and angle of the rotor pump to ensure that the amount of material output each time is accurate and stable, meeting the preset metering requirements. The metered material is then transported to the bag - making former part of the vertical packaging machine.
- **Bag - making and Packaging**: The packaging film is formed into the shape of a bag through the bag - making former, and at the same time, the material is injected into the bag. Subsequently, the packaging machine performs sealing operations such as longitudinal sealing and transverse sealing to seal the material inside the bag, completing the bag - making and packaging process.
2. **Main Structure**:
- **Servo Rotor Pump**: This is the core component of the packaging machine. The design and processing precision of its rotor and pump casing directly affect the material transportation accuracy and stability. High - quality rotor pumps have characteristics such as wear resistance, corrosion resistance, and good sealing performance, and can adapt to materials of different properties.
- **Vertical Packaging Machine Part**: It includes a bag - making former, a film - pulling device, a sealing device, a cutting device, a control system, etc. The bag - making former determines the shape and size of the bag; the film - pulling device is responsible for pulling the packaging film smoothly through the machine; the sealing device seals the bag; the cutting device cuts and separates the packaged bags one by one; and the control system precisely controls and monitors the entire packaging process.
3. **Application Range**:
- **Food Industry**: It can be used to package various sauces, condiments, and liquid foods such as hot pot base materials, jams, ketchup, salad dressings, honey, and milk.
- **Pharmaceutical Industry**: It is suitable for packaging traditional Chinese medicine liquids, oral liquids, eye drops, and other pharmaceutical preparations.
- **Chemical Industry**: It can package chemical products such as hand sanitizers, laundry detergents, disinfectants, foliar fertilizers, and cosmetic samples.
4. **Advantageous Features**:
- **High Metering Accuracy**: The precise control of the servo motor combined with the stable transportation of the rotor pump results in high metering accuracy of the packaging machine, which can meet the packaging requirements of products with strict metering requirements.
- **Fast Packaging Speed**: The automated operation process and efficient mechanical structure ensure that the packaging machine has a high packaging speed and can meet the needs of large - scale production.
- **Wide Applicability**: For materials of different viscosities and properties, such as high - viscosity sauces and liquids with good fluidity, the vertical packaging machine with servo rotor pump can adapt well.
- **Convenient Operation and Maintenance**: The control system of the packaging machine usually adopts touch - screen operation with a user - friendly interface, making it easy to set and adjust packaging parameters. At the same time, the equipment's structural design is reasonable, facilitating daily maintenance.
