When it comes to the material control structure of the open-mouth packaging machine, the following is a brief analysis and introduction of the common structures:
1.Spiral forced feeding: The spiral forced feeding structure pushes the materials into the packaging bags through the rotation of the spiral. The spiral structure has a stable material conveying capacity and is suitable for granular or powdery materials with good fluidity.
2. Horizontal or Vertical Impeller Feeding: The horizontal or vertical impeller feeding structure uses the rotating impeller to push the materials forward, achieving the transportation of the materials. The impeller structure is suitable for the transportation of granular or block-like materials, and the rotational speed and feeding volume of the impeller can be adjusted as needed.
3. Air-flow feeding: The air-flow feeding structure utilizes the force of the air to blow the materials into the packaging bags. The air-flow feeding structure can achieve rapid and continuous material transportation, and is suitable for lightweight materials or those requiring precise control in packaging.
4. Spiral and impeller mixed feeding: The spiral and impeller mixed feeding structure combines the advantages of both the spiral and the impeller, achieving more flexible and efficient material transportation. This structure is suitable for various types of materials and has good adaptability and stability.
5. Gravity feeding: The gravity feeding structure uses the gravitational force of the materials to direct them towards the packaging bags. This structure is simple and reliable, and is suitable for packaging granular or powdered materials, especially those with good fluidity.
The above is a simple analysis and introduction of several common material control structures for open-pocket packaging machines. The selection of the appropriate structure should be based on the characteristics and fluidity of the materials as well as the packaging requirements, in order to ensure accurate material measurement and a stable packaging process.
