Double-head liquid filling machine: efficient and accurate liquid filling solution

　　Liquid products are widely used in food, pharmaceutical, chemical, daily chemical and other industries, the quality of its packaging and production efficiency directly affects the market competitiveness of the product. The traditional manual or single-head filling method is often inefficient and difficult to meet the needs of modern production. The emergence of double-head liquid filling machine, greatly improving production efficiency and filling accuracy, has become an important equipment for liquid packaging in various industries.

　　First, the working principle of the double-head liquid filling machine

　　Double head liquid filling machine adopts double filling head synchronous operation, can fill two bottles at the same time, improve production efficiency. Its workflow is as follows:

　　1. Automatic feeding: the liquid enters the filling machine through the pipeline or liquid storage tank, and the liquid is delivered by negative pressure suction, pneumatic pressure push or piston pump metering.

　　2. Accurate filling: the equipment ensures accurate and consistent filling amount of each bottle of liquid through piston, flow meter or gravity filling methods.

　　3. Anti-drip control: Adopting anti-drip filling nozzle ensures no dripping during the filling process, keeps the bottle mouth clean and improves product quality.

　　4. Synchronized operation, improve efficiency: dual-head design can fill two bottles of liquid at the same time, compared with single-head filling efficiency doubled, suitable for small and medium-sized enterprises mass production.

　　5. Intelligent control system: PLC control system is adopted, equipped with touch screen operation interface, which can accurately set the filling parameters and realize fully automatic or semi-automatic operation mode.

　　6. Conveying and sealing (optional): after filling, the product can automatically enter the conveyor belt, and docking sealing, labeling, packaging and other subsequent processes to improve the level of production automation.

　　Second, the main features of double-head liquid filling machine

　　1. Efficient double-head filling, increase production capacity: double filling heads work synchronously, doubling the efficiency, suitable for medium-sized production needs.

　　2. Accurate filling, small error: the use of high-precision flow meter or piston metering system, filling error can be controlled within ± 1%, to ensure stable product quality.

　　3. Applicable to a variety of liquids: it can be applied to water, fruit juice, milk, edible oil, cosmetics, medicinal liquid, chemical reagent and other liquid products, with strong compatibility.

　　4. Intelligent operation, easy to adjust: Equipped with PLC control system and touch screen, it can adjust the filling speed and filling volume, and the operation is simple and intuitive.

　　5. Anti-drip and anti-foam design: Adopt anti-drip filling valve to ensure no dripping during the filling process, suitable for liquids with more foam (e.g. disinfectant, shampoo, etc.).

　　6. Stainless steel material, in line with health standards: most of the equipment is made of 304 or 316L stainless steel, corrosion-resistant, in line with the hygiene standards of food, pharmaceutical and other industries.

　　7. Strong flexibility and compatibility: adjustable filling range, adapt to different specifications of bottles, such as glass bottles, plastic bottles, metal containers.

　　8. Strong expandability: it can be matched with automatic bottle loading, capping, labeling, packaging and other subsequent equipment to form a fully automatic production line and improve the level of automation.

　　Application fields of double-head liquid filling machine

　　1. Food industry: it is suitable for precise filling of juice, milk, edible oil, honey, condiment (soy sauce, vinegar), beverage and other liquid food.

　　2. Pharmaceutical industry: It is used for aseptic filling of medical products such as medicine, disinfectant solution, saline, oral solution, etc. to ensure the safety of medicines.

　　3. Chemical industry: it is suitable for precise filling of paints, solvents, cleaning agents, lubricants, chemical reagents and other liquids, reducing waste and pollution.

　　4. Daily chemical industry: suitable for automated filling of shampoo, shower gel, hand soap, make-up, skin care products and other daily chemical products, to ensure the appearance of neat.

　　5. Agricultural industry: suitable for pesticides, liquid fertilizers, plant nutrient solution and other liquid packaging in agricultural production, improve filling safety.

　　Fourth, the future development trend

　　With the development trend of automation, intelligence, green environmental protection, double-head liquid filling machine will continue to optimize and upgrade, the main direction of future development include:

　　1. Intelligent and digital upgrading: combined with artificial intelligence (AI) and the Internet of Things (IoT), to achieve remote monitoring, intelligent maintenance and improve production efficiency. Adopt big data analysis to optimize filling parameters, improve accuracy and reduce waste.

　　2. High-precision and flexible production: Develop higher-precision flow meters or mass flow control systems to reduce errors and improve product consistency. In the future, the equipment will further support the rapid switching of multi-size bottles and liquid categories to improve production flexibility.

　　3. Environmental protection and energy saving technology: adopt low energy consumption drive system to reduce energy consumption and improve sustainability. Research and development of filling technology applicable to biodegradable environmental protection packaging, and promote the development of green packaging industry.

　　4. Automation integration: the future of the double-head liquid filling machine will be more integrated automatic bottling, capping, labeling, coding, packaging and other processes, the formation of unmanned production lines, reduce labor costs.

　　5. Stricter safety and health standards: for the food and pharmaceutical industries, the equipment will adopt aseptic filling technology, in line with GMP (Good Manufacturing Practice) standards to ensure product safety. Adopt explosion-proof design to ensure the safety of filling flammable and explosive liquids in chemical industry.

　　With the features of high efficiency, precision and intelligence, the double-head liquid filling machine has been widely used in many industries, such as food, medicine, chemical, daily chemical and so on. With the development of science and technology, the equipment will be upgraded in intelligence, energy saving and environmental protection, automation integration, etc., to provide strong support for enterprises to improve production efficiency, reduce costs and improve product quality. In the future, the double-head liquid filling machine will be driven by intelligent manufacturing, help the liquid packaging industry to move to a higher level of development, to create greater value for the enterprise.
