Liquid packaging machine is an integrated automatic equipment designed for the complete packaging process of liquid products, covering container feeding, liquid metering, filling, sealing, labeling, coding, and finished product collection, and is widely used in the cosmetics, food, beverage, medicine, chemical, and daily chemical industries for the packaging of various liquid products such as water, oil, lotion, essence, reagent, and detergent. Discus (Shenzhen) Technology Co., Ltd., founded in 2018 and specialized in the R&D, production, and installation of industrial packaging equipment, has developed a series of liquid packaging machines with high automation, high integration, and strong adaptability, complying with international quality standards such as CGMP, CE, FDA, and ISO 12100:2010, and can be customized according to the specific characteristics of customers’ liquid products and packaging requirements. The liquid packaging machine is composed of multiple functional modules that work closely together to form a complete packaging line. The container feeding module adopts an automatic bottle unscrambler or pouch feeding mechanism, which can automatically sort and convey empty containers (bottles, pouches) to the filling station, ensuring orderly and efficient feeding; the metering and filling module is the core of the equipment, adopting high-precision piston pumps, gear pumps, flow meters, or volumetric filling systems, with a filling precision controlled within ±0.5%, adapting to the filling of liquid products with different viscosities (low, medium, high) and properties (corrosive, foaming, sterile), and the filling volume can be steplessly adjusted according to the packaging specifications. The sealing module adopts corresponding sealing technologies according to the container type: for bottles, it uses screw capping, snap capping, induction sealing, or aluminum cap crimping technology, ensuring firm and leak-proof sealing; for pouches, it uses heat sealing, ultrasonic sealing, or three-side/four-side sealing technology, with adjustable sealing temperature and pressure, ensuring the sealing strength and appearance quality of the pouch. The labeling and coding module can realize the automatic labeling of product information (brand logo, specifications, ingredients) and the coding of production date, batch number, and shelf life, with high labeling precision and clear coding, facilitating product quality traceability and market management. The finished product collection module adopts a conveyor belt and sorting mechanism to automatically collect and sort the packaged finished products, improving the efficiency of subsequent storage and transportation. All parts in contact with liquid are made of food-grade 304/316 stainless steel and corrosion-resistant engineering plastics, meeting the hygiene and safety requirements of food, cosmetics, and pharmaceutical production, and the structural design of the equipment is closed and dustproof, preventing secondary pollution of the liquid product during the packaging process. The liquid packaging machine is equipped with a PLC control system and a large-size touch screen human-computer interaction interface, which can realize centralized control and real-time monitoring of the entire packaging line, store multiple sets of production recipes (up to 100 sets), realize quick switching between different products and different packaging specifications, and automatically record production data such as output, filling volume, and packaging speed, facilitating enterprise production management and quality control. The equipment has a high production efficiency, with a packaging speed of 30-2000 bottles per minute (for bottle packaging) or 50-500 pouches per minute (for pouch packaging), which can be adjusted according to the production needs, suitable for both small-batch customized production and large-scale mass production. In practical application scenarios, a large mineral water production enterprise in South China adopted the company’s liquid packaging machine for its 500ml and 1.5L PET bottle mineral water packaging line, configuring the bottle unscrambler, precision filling machine, screw capping machine, self-adhesive labeling machine, and carton packing machine, realizing a production capacity of 12000 bottles per hour, a product qualification rate of 99.95%, and a labor cost reduction of more than 80% compared with the traditional semi-automatic packaging line. A high-end cosmetic enterprise in Europe adopted the equipment for its facial essence and perfume packaging line, using glass bottles as containers, matching with sterile filling machines, ultrasonic capping machines, laser labeling machines, and shrink wrapping machines, ensuring the sterility and high-end quality of the products, with a production capacity of 3000 bottles per hour. The company can customize the liquid packaging machine according to the customer’s specific liquid product characteristics (viscosity, corrosivity, foaming property, sterility requirement), container type (bottle, pouch, can, barrel), packaging specifications, and production scale, such as adding a sterile packaging module for medical products, optimizing the degassing system for foaming liquids, and increasing the number of filling heads to improve production capacity, and provide one-stop solutions including equipment design, manufacturing, installation, commissioning, technical training, and after-sales maintenance.
