Liquid filling systems are a set of highly integrated and customizable intelligent production systems that integrate liquid storage, metering, filling, conveying, detection, and control functions, designed to meet the automated filling needs of liquid products in various industries such as cosmetics, food, medicine, chemical, and daily chemical, and can be seamlessly connected with other production equipment to form a complete automatic production line. Discus (Shenzhen) Technology Co., Ltd., founded in 2018 and specialized in the R&D, production, and installation of industrial filling equipment, has developed a series of liquid filling systems with strong scalability, high automation, and good compatibility, which are independently designed and developed with multiple utility model patents for core components, complying with CGMP, CE, FDA, and ISO 12100:2010 international standards, and can be customized according to the actual production needs of customers. The liquid filling system is composed of six core functional units: a closed liquid storage unit, a high-precision metering unit, a multi-station filling unit, a synchronous conveying unit, an intelligent detection unit, and a central control unit, with each unit adopting a modular design, which can be flexibly combined, added, or reduced according to the customer's product characteristics, production scale, and workshop layout, realizing personalized customization of the filling system. The closed liquid storage unit is equipped with a stirring, heating, and insulation device, suitable for the storage of liquid products with different viscosities, and the sealed structure prevents liquid volatilization and contamination; the high-precision metering unit is available in multiple types such as volumetric metering, mass metering, and flow metering, with a metering precision of up to ±0.1%, meeting the filling precision requirements of different liquid products. The multi-station filling unit can be configured with 2-32 filling heads according to the production capacity, and the filling heads are independently controlled, which can realize simultaneous filling of multiple packaging containers, and the filling mode can be switched between gravity filling, pressure filling, vacuum filling, and piston filling to adapt to the filling of low, medium, and high viscosity liquids. The synchronous conveying unit adopts a high-precision servo conveyor belt and a bottle/pouch positioning device, ensuring the orderly conveying and accurate positioning of packaging containers, and the conveying speed is synchronized with the filling speed to realize efficient and coordinated production. The intelligent detection unit is equipped with high-precision sensors, vision inspection systems, and weight detection systems, which can realize real-time detection of filling volume, packaging container integrity, and liquid leakage, and automatically remove unqualified products, ensuring the qualification rate of finished products. The central control unit is based on a PLC control system and a touch screen human-computer interaction interface, which can realize centralized control of the entire filling system, store multiple sets of production recipes, realize quick switching between different products, and automatically record production data such as filling volume, production quantity, and production time, facilitating enterprise production management and product quality traceability. The liquid filling system has strong compatibility and can be seamlessly connected with capping machines, labeling machines, coding machines, and packaging machines to form a complete automatic production line from liquid filling to finished product packaging. In practical application scenarios, a high-end cosmetic production enterprise in South China adopted the company’s liquid filling system for its facial toner, lotion, and essence production line, configuring 16 filling heads and realizing a production capacity of 6000 bottles per hour, with a product qualification rate of 99.95% and a labor cost reduction of more than 70% compared with the traditional semi-automatic filling mode. The company has a professional R&D and design team composed of mechanical engineers, electrical engineers, and industrial designers, which can provide one-stop solutions for customers including system design, equipment manufacturing, installation, commissioning, technical training, and after-sales maintenance, and provide timely technical support and spare parts supply during the use of the system. With advanced technology, strong scalability, and reliable performance, the liquid filling systems of Discus (Shenzhen) Technology Co., Ltd. have become an important guarantee for enterprises in various industries to realize the intelligent and automated upgrading of liquid product production.
