In modern industrial production, the degree of packaging automation directly affects the production efficiency and market competitiveness of enterprises. Traditional packaging methods are not only inefficient, and prone to uneven packaging, sealing is not firm and other problems, can not meet the market demand for high-quality packaging. The emergence of automatic vertical packaging machine has completely changed the status quo. It combines automatic bag making, weighing, filling, sealing, marking, cutting and other functions in one, greatly improving production efficiency, widely used in food, medicine, chemical, hardware, daily chemical and other industries.

　　First, the working principle of automatic vertical packaging machine

　　Full-automatic vertical packaging machine mainly relies on advanced PLC intelligent control system to complete the packaging process through automatic feeding, measuring, bag making, filling, sealing and finished product output and other steps. Its workflow is as follows:

　　1. Automatic feeding: adopt screw conveyor, vibrating feeder or belt conveyor to convey the materials to the measuring device.

　　2. Accurate weighing and metering: through electronic weighing sensor, volumetric metering or screw metering to ensure that the weight of each bag is accurate.

　　3. Bag making and molding: Adopting automatic bag making technology, the packaging film is shaped into bags by unfolding the rolled film, pulling the film, and folding it by the molding machine.

　　4. Filling materials: the equipment adopts different filling methods according to the product characteristics, such as screw discharging, piston pump filling, gravity filling and so on.

　　5. Sealing and cutting: adopting hot sealing, cold sealing or ultrasonic sealing technology to ensure that the bags are sealed firmly and beautifully. After sealing, the bag is cut off to complete a complete packaging process.

　　6. Automatic coding and output: the equipment can be equipped with code printer, labeling machine and other functions, print the production date, batch number and other information, and automatically convey the finished product.

　　Second, the main features of automatic vertical packaging machine

　　1. High-efficiency automation, improve production efficiency: the equipment can run continuously at high speed, packaging speed up to 30120 packages / minute, significantly improving production efficiency.

　　2. Compatible with a variety of packaging materials: suitable for plastic film, composite film, aluminum foil bags, kraft paper bags and other packaging materials, to meet the needs of different products.

　　3. Accurate measurement, small error: adopting high precision measuring device, the error can be controlled within ±1%, to ensure that the weight of each bag of products is accurate.

　　4. Suitable for a variety of materials: can pack different materials such as powder, granule, liquid, paste, etc., suitable for food, pharmaceutical, chemical and other industries.

　　5. Intelligent control, convenient operation: PLC + touch screen operating system, free to set parameters, real-time monitoring of production conditions, simple and intuitive operation.

　　6. Firm sealing, beautiful packaging: adopting high temperature heat sealing or ultrasonic sealing technology to ensure that the bag sealing is smooth, beautiful and pressure-resistant.

　　7. Dustproof and anti-pollution, hygiene and safety: the equipment can be equipped with dust cover, de-static device, airflow cleaning system, to ensure the hygiene standard of food and pharmaceutical industry.

　　8. Strong expandability and compatibility with automatic production line: it can be linked with automatic loading machine, conveyor belt, coding machine, metal detecting machine and other equipments to form a full-automatic packaging production line.

　　Application fields of automatic vertical packaging machine

　　1. Food industry: it is suitable for packing rice, nuts, candy, potato chips, flour, milk powder, seasoning, coffee powder, instant drink powder and other food products.

　　2. Pharmaceutical industry: It is suitable for packaging of Chinese medicine powder, health care granules, punch, oral liquid, tablets and other pharmaceutical products to ensure accurate quantitative and hygienic safety.

　　3. Chemical industry: It is suitable for sealing packaging of washing powder, pesticide powder, plastic granule, dye powder and other chemical products to prevent moisture and pollution.

　　4. Daily chemical industry: It is suitable for the packaging of liquid or cream products such as laundry detergent, shower gel, shampoo, toothpaste and skin care products.

　　5. Hardware industry: It is suitable for the packaging of screws, nails, electronic components, plastic parts and other small hardware products to ensure accurate quantity.

　　Fourth, the future development trend

　　With the advancement of intelligent manufacturing and industry 4.0, the automatic vertical packaging machine is developing in the direction of smarter, more environmentally friendly and more efficient, the main trends include:

　　1. Intelligent and digital upgrading: combining AI artificial intelligence, big data, and Internet of Things (IoT) technology to realize remote monitoring, intelligent maintenance, automatic fault diagnosis, and improve production management efficiency.

　　2. Multi-functional integrated design: future equipment will integrate more functions, such as automatic detection, dust removal, vacuum nitrogen filling, anti-static, etc., to improve packaging quality.

　　3. Flexible production, improve adaptability: the equipment will support a key to switch the packaging specifications, to adapt to different sizes and materials of the bag, improve production flexibility.

　　4. Environmental protection and energy-saving technology: adopting energy-saving drive system to reduce energy consumption, and compatible with biodegradable and environmentally friendly packaging materials to help green production.

　　5. Intelligent anti-counterfeiting and traceability system: the future equipment will be equipped with two-dimensional code spraying, RFID traceability system to ensure product quality and safety, to meet the traceability needs of the food and pharmaceutical industries.

　　With the features of high efficiency, precision and intelligence, the automatic vertical packaging machine has become an indispensable packaging equipment for food, pharmaceutical, chemical, hardware, daily chemical and other industries. It not only improves production efficiency and reduces labor costs, but also improves the quality and aesthetics of product packaging. In the future, with the development trend of intelligence, environmental protection and flexibility, the automatic vertical packaging machine will be constantly upgraded to bring higher production benefits for enterprises and help the packaging industry to move towards a higher level of development.
