Analysis of the Development Prospects of Weighing Liquid Filling Machines
1、 Overview of past filling machinery
The so-called filling machinery usually refers to a machine that fills liquid products into packaging containers. The filling production line refers to the route formed by a series of production activities, including processing, transportation, assembly, and inspection, starting from the raw materials entering the packaging equipment. The filling production line has great flexibility and can be widely used in the production and processing of various products. However, in the past, due to limitations in technological level, the filling production line system had many shortcomings, such as expensive procurement costs, large equipment volume, difficult installation, and high maintenance costs. Therefore, for a long time, the filling machine production line was not given enough attention and was not widely promoted and applied.
2、 Analysis of the Development Prospects of China's Weighing Liquid Filling Machine Market
In the future, liquid filling machines will cooperate with the development trend of industrial automation, and move towards diversified mechanical functions, standardized structural design, intelligent machine control, and high-precision structure in technological development. The application of the new filling machine production line has achieved high-speed, large-scale, and high-quality production in modern processing industries such as food, medicine, and daily chemical enterprises.
In the liquid filling industry, gravity filling machines and volumetric filling machines are widely used based on their different working principles.
Volumetric filling machines include flow meter filling machines, plunger filling machines, etc. Taking the flowmeter filling machine as an example, it refers to installing a high-precision electronic flowmeter on the pipeline of each filling valve to achieve quantitative filling by measuring the volume of liquid filled. The advantage is that the equipment structure is simple, the filling valve design is simple, and there is no need to configure a buffer tank; Automatic cleaning is thorough and convenient, and the filling valve does not touch the bottle mouth during operation, ensuring cleanliness and hygiene; When the filling volume needs to be adjusted, simply modify the parameters without replacing any parts; By adjusting individual filling stations, the filling volume of each station can be highly consistent. This filling method has high accuracy for filling liquids of various viscosities without gas, and is widely used by domestic and foreign enterprises. However, due to the performance of the flowmeter itself, this filling method cannot handle materials without conductivity or containing gas. Because non-conductive liquids, such as edible oil, cannot be measured by flow meters. Materials containing gases can lead to increased measurement deviation and are therefore not suitable for use.
