Description

TECHNICAL FIELD

[0001] The utility model relates to the field of filling technology, more particularly to a quantitative cylinder and a filling quantitative system for filling materials. BACKGROUND

[0002] In current filling technology, many filling devices use filling heads that directly participate in the quantitative filling of materials. Common filling methods include piston type, flow type, gravity type, and pressure type, etc. Among them, the filling head usually realizes quantitative control by directly controlling the flow or volume of the material, which leads to problems such as inaccurate quantitative, poor adaptability, etc. in the filling process.

[0003] Inaccurate quantitative: When the filling head directly participates in the quantitative filling, due to the influence of material rheological properties (such as viscosity, fluidity) and filling environmental factors (such as temperature, pressure), it is easy to cause the fluctuation of filling quantity. For example, for high-viscosity materials or liquids with foam, overfilling or underfilling may occur during the quantitative filling process. In addition, aging, wear and tear or contamination of the equipment may also cause quantitative errors, affecting the consistency in the production process.

[0004] Poor adaptability: Most traditional filling devices are designed for specific types of materials, lacking strong adaptability. Especially when different specifications or different types of materials need to be frequently switched during the production process, the adjustment of traditional devices is difficult and inefficient. The design of the filling head often cannot quickly adapt to different material properties, resulting in low equipment operation efficiency and prolonged production cycle.

[0005] In summary, the existing filling technology still has many shortcomings in realizing accurate quantitative and improving adaptability. These problems not only affect production efficiency and product quality, but also may bring high production cost. Therefore, a new technical solution is urgently needed to overcome the defects in the existing technology and improve the precision, efficiency and reliability of the filling process.
