Analysis of the status quo of rotary packing machine in China
With the improvement of people’s awareness of product packaging, the society’s demand for packaging machines has also increased significantly. At the same time, the requirements for food production and packaging quality, hygiene and safety are becoming more and more stringent, which requires us to design and manufacture an automation The rotary packing machine with high degree and good reliability can meet the market demand and user requirements of bagged food.

Since the industrial revolution, the mechanized production mode has gradually replaced the traditional manual production mode, and people’s packaging awareness has become higher and higher. The packaging industry has developed rapidly. For example, fully automatic bag packaging machines have replaced manual production modes and realized automated packaging. . The automatic production process is as follows: Put the packaging bag at the bag taking device, the robot will automatically follow the track to take the bag, and send it to the next station for bag clamping, coding, bag opening, blanking, vibration, exhaust, and sealing , Output and other operations. The bag-feeding packaging machine is mainly composed of PLC control system, bag opening guide device, coding machine, vibration device, dust removal device, solenoid valve, temperature controller, vacuum generator or vacuum pump, inverter, output system and other components; The optional configuration is material measuring filling machine, material elevator, vibrating feeder, working platform, weight sorting scale, finished product conveying elevator, etc.; the whole process of packaging machine operation does not require manual participation, which saves costs and reduces costs , It also improves production efficiency [2,3]. It has a wide range of applications. It can be used for paper-plastic composite, aluminum-plastic composite, plastic-plastic composite, PE composite and other film bags; in addition, it can also be used in one machine for multiple purposes. It can be equipped with corresponding metering devices according to material changes to achieve block, granule, powder Fully automated packaging of other products.

At present, the demand for packaging machines is growing at a rate of 12% each year, and my country's packaging machinery products are growing rapidly at an average annual rate of more than 30%. The renewal speed of packaging machinery is very fast. Continuous production requires packaging machinery operations to become an automated production line composed of a series of automated packaging machinery, conveyors, linkages, automatic storage and automatic detection devices. Mechanical automation is mainly to apply automation technology in the production process, optimize the production process and accelerate the processing exchange and flow speed of production, thereby improving the efficiency of packaging. The level of automation technology has a great impact on the development of the entire machinery manufacturing industry. For example, the use of fieldbus technology in the entire packaging process of medicines. A series of automated machinery replaces manual complex operations, making production accurate and reliable, and reducing resources Waste has improved production efficiency and accelerated industrial development.
