With the continuous development of industrial automation and intelligent manufacturing technology, the packaging industry has also ushered in a huge change. As an important equipment in the modern packaging industry, the automatic quantitative packaging machine is widely used in many industries such as food, chemical and pharmaceutical by virtue of its high efficiency and accuracy. This kind of equipment can automatically complete the measurement of materials in the production process, filling, sealing and other links, not only to improve production efficiency, but also to ensure the stability of product quality. In this paper, we will discuss the working principle of automatic quantitative packaging machine, application areas, equipment features and the advantages it brings.

　　First, the working principle of automatic quantitative packaging machine

　　Automatic quantitative packaging machine workflow mainly includes material transportation, measurement, filling, sealing and output of several key steps. The specific working principle is as follows:

　　1. Material conveying: the material is sent to the packaging machine from the hopper or raw material warehouse through the automatic conveying system. According to different material characteristics, the commonly used conveying methods are vibration conveying, screw conveying, etc., to ensure that the material flows evenly.

　　2. Quantitative measurement: this is the core link of automatic quantitative packaging machine, the equipment usually adopts high-precision electronic measurement system (such as electronic weighing, volumetric measurement, etc.), according to the standard set to accurately measure the amount of material required in each bag. The measuring accuracy of the equipment directly affects the quality and consistency of packaging.

　　3. Automatic Filling: When the metering system determines the amount of material required, the equipment accurately conveys the material into the bag through the filling device. For liquid materials, liquid filling head may be used; for powder or granular materials, screw feeding device or vibrating feeding system is usually used.

　　4. Sealing and coding: after the filling is completed, the bags are sealed through the sealing device, common sealing methods such as heat sealing, pressure sealing. For products that need to trace information, the equipment is also equipped with a coding system, which can print the production date, batch number, barcode and other information on the bags.

　　5. Finished product output: Finally, the sealed bags are transferred to the next link through the conveyor belt, such as inspection, boxing, etc., forming a complete packaging process.

　　Second, the application field of automatic quantitative packaging machine

　　Automatic quantitative packaging machine is widely used, especially in the following industries is particularly prominent:

　　1. Food industry: the food industry has high requirements for packaging accuracy and hygiene. Fully automatic quantitative packaging machine is widely used in the packaging of rice, flour, sugar, milk powder, seasoning, nuts and other products. It can not only ensure the accurate quantity of materials in each bag, but also avoid material waste, reduce manual contact and improve food safety.

　　2. Chemical industry: Many materials in the chemical industry, such as pigments, additives, fertilizers, etc., are usually powder or granular materials, and have a certain degree of danger. Automatic quantitative packaging machine can ensure accurate measurement and avoid material leakage through the closed design, to enhance the safety of the production process and environmental protection.

　　3. Pharmaceutical industry: the pharmaceutical industry has very high requirements for packaging precision and safety. Automatic quantitative packaging machine in the packaging of drugs, health care products and medical devices, to ensure that the dose of each product is consistent, to avoid errors and pollution, in line with strict health standards.

　　4. Daily chemical industry: in the packaging of daily chemical products such as laundry detergent, cosmetics, skin care products, accurate quantitative packaging is particularly important. Full-automatic quantitative packaging machine can realize different specifications of packaging needs, enhance the appearance of the product and brand value.

　　Third, the automatic quantitative packaging machine equipment features

　　1. High-precision measurement system: automatic quantitative packaging machine is usually equipped with high-precision electronic weighing device, which can ensure that the weight or volume of each bag is accurate and consistent, to avoid over or under, reduce waste, and ensure that the economic benefits of production.

　　2. High degree of automation: the equipment is operated through PLC control system and touch screen interface, the staff can easily set the packaging parameters, equipment monitoring and adjustment, reducing human intervention and improving the automation level of the production line.

　　3. Flexible adaptability: automatic quantitative packaging machine can be adapted to a variety of packaging forms, such as bags, bottles, cans, etc., and at the same time be able to cope with the packaging needs of different materials, whether it is a liquid, powder, granules, the equipment is able to provide accurate packaging solutions.

　　4. Hygienic design: Many automatic quantitative packaging machines are made of food-grade stainless steel, in line with hygiene standards, especially for the food and pharmaceutical industries. In addition, equipment design is often considered easy to clean and maintain, reducing the risk of cross-contamination.

　　5. Energy saving and environmental protection: With the enhancement of environmental awareness, many automatic quantitative packaging machine in the design of energy-saving solutions to reduce energy consumption and optimize the production process, improve the overall effectiveness of the equipment.

　　Fourth, the advantages of automatic quantitative packaging machine

　　1. Improve production efficiency: automated packaging process does not require human intervention, the equipment can continue to quickly complete the packaging task, greatly improving the efficiency of the production line, suitable for mass production.

　　2. Reduce labor costs: the high degree of automation of the equipment reduces the dependence on manual operation and reduces the labor cost of enterprises. Especially in areas with high labor costs, automated equipment can help companies reduce production costs and improve profitability.

　　3. Ensure packaging accuracy: the precision metering system of automatic quantitative packaging machine can ensure the packaging accuracy, improve the consistency of the quality of each product and enhance customer satisfaction.

　　4. Enhance the competitiveness of enterprises: automatic quantitative packaging machine can reduce the production cycle, increase the market response speed of the product, enhance the production flexibility of enterprises, and enhance the competitiveness of enterprises in the market.

　　Automatic quantitative packaging machine with its high precision, high efficiency and high automation characteristics, has become an indispensable packaging equipment in various industries. It not only improves production efficiency and reduces labor costs, but also ensures packaging precision and quality consistency. With the advancement of intelligent manufacturing and the continuous upgrading of technology, the future automatic quantitative packaging machine will continue to develop in the direction of higher automation and intelligence to meet the needs of more industries and promote the innovation and progress of the global packaging industry.
