Liquid filling line

Abstract：This paper is mainly aimed at the Part design of liquid filling line. With the strong development of packaging machinery in China, more and more enterprises are engaging in this industry. They will choose appropriate method about the filling technology, and set by the product requirements. This design consist of three parts of quantitative cup filling body, plate conveying mechanism and PLC. Quantitative cup method has simple structure, abundant functional characteristics and high efficiency .Plate transportation agency is quite mature. Line layout is exquisite, flexible and strong carrying capacity. Transfer speed is very fast. Conveyor chain length is longer enough to be suitable for working conditions of long distance transport, so plate conveying mechanism widely used in the transportation industry. Science and technology brings us convenient, and also turns down labor. Automation control is one of our goals, PLC realize that the product produce orderly, at the same time, PLC could monitor the production process. Liquid filling line’s requirement is stable running, reliable, without doubt, we also hope that Liquid filling line is suitable for various occasions.

Keywords:  filling; line design ; control ; PLC
