As the demand of the food industry continues to diversify, in order to meet these needs and to gain a place in the international competition, packaging machinery companies are gradually realizing that the new and more automated packaging models will gradually replace the tradition into the mainstream of the future. This is an effective way for packaging machinery companies to achieve sustainable development and is also the goal of their technological reform.
Under the joint effect of labor cost, environmental cost and resource depletion cost, the economic development has entered a high-cost era, which has also promoted the development of industrial automation as an irreversible development trend. At the same time, packaging equipment should also follow the trend. After the automation of the machine, the possibility of the operator touching the dangerous parts of the machine can be greatly reduced, and the safety performance will be significantly improved. In addition, the modified equipment will greatly improve the production efficiency and reduce the efficiency. The labor intensity of laborers saves labor and brings huge economic benefits to enterprises.
Today, as the packaging industry continues to grow, market demand continues to diversify. In order to promote the development of the entire industry, automated packaging machinery has become an enterprise.
Under the stimulus of the economy, China's packaging industry has continued to develop and has become the second largest packaging country in the world. However, the development of functional components and numerical control systems is still lagging behind. The manufacturing technology of packaging machinery enterprises is uneven, and the manufacturing capacity is relatively biased. weak.
In the process of die-cutting, each new product needs to have a special die-cutting machine to make the corresponding template according to the graphics and size. It is necessary to replace the template once, which is not only time-consuming and laborious, but also increases. Made in this book, but this molding technology has been successfully applied in the sheet metal industry for many years, such as CNC punching, he only needs to input the parameters such as graphics and size, and set the corresponding production quantity, it is easy to change the order, and can support the column. Array order, why is the existing mature technology not used in the packaging industry? It can be seen that China's packaging machinery industry still has a large development space compared with the international advanced level in terms of product quality stability and reliability. Excessive technological dependence leads to the lack of high-tech support in the industry, which lags behind the independent innovation of the industry.
China's packaging machinery industry has great potential for development. Whether it can seize these opportunities will be the key to the future development of packaging manufacturers. With the continuous development and advancement of technology, future microelectronics, computers, industrial robots, image sensing technology and new materials will be more and more widely used in packaging machinery. Enterprises need to learn and introduce new technologies. It is marching into packaging equipment with high production efficiency, high degree of automation, good reliability, flexibility and high technical content. To create a new type of packaging machinery, packaging machinery to the direction of integration, chemical, intelligent and other development.
The control system plays an important role. From the market competition of various enterprises, the cycle of product renewal is becoming shorter and shorter, which has high requirements for the automation and flexibility of packaging machinery, that is, the life of packaging machinery is far greater. In the life cycle of the product. Only in this way can we meet the economic requirements of product production. This led us to begin to examine the connotation of the concept of flexibility, namely the flexibility of quantity, the flexibility of construction and the flexibility of supply. The flexibility of supply also involves the motion control system of the packaging machine.
Specifically, in order to make the packaging machinery have good automation and flexibility, and to improve the degree of automation, it is necessary to adopt microcomputer technology, functional module technology, and monitor the work of multiple robots at the same time, so that the requirements for product changes can be transferred only by the program. .
In the process of industrialization of the packaging industry, manufacturing technology has completed scale and diversification, and the demand for diversification and even individualization has further intensified market competition. In order to reduce production costs, packaging companies have considered constructing flexible production lines, and it is indispensable to complete flexible manufacturing. The servo control system provides support. Control and integrated products/technologies play an increasingly important role in the development of packaging production lines.
In order to complete the flexible production, it is required that the various process sections in the packaging production line are closely coupled with each other, and the packaging production line is required to be linked with other production lines. Because different controllers control different process segments or production pipelines separately, this brings about different problems between controllers. Therefore, the International Packaging Association User Organization (OMAC/PACML) has stated the structured, standardized machine state management functions of object packaging. Accordingly, the control system integrated with this function can ensure that users complete the entire line with less time and cost. And even the synergy of the whole plant production.
The structure of China's packaging industry has been continuously adjusted with the development of the automation industry. At the same time, technological progress has accelerated the transformation of the new industrialization road of sustainable development. The development of the packaging industry requires a close combination of packaging technology and automation, and accelerates the development of automated control systems for packaging machinery. Throughout China's packaging market, the packaging machinery industry has a very large space for development. Enterprises continue to look for gaps, learn new technologies, and update technology to integrate them into traditional mechanical manufacturing technologies, so that soft power and hard power can be integrated. To ensure the development of social support.

Spunbond fabrics are produced by depositing extruded, spun filaments onto a collecting belt in a uniform random manner followed by bonding the fibers. The fibers are separated during the web laying process by air jets or electrostatic charges. The collecting surface is usually perforated to prevent the air stream from deflecting and carrying the fibers in an uncontrolled manner. Bonding imparts strength and integrity to the web by applying heated rolls or hot needles to partially melt the polymer and fuse the fibers together. Since molecular orientation increases the melting point, fibers that are not highly drawn can be used as thermal binding fibers. Spunbond products are employed in carpet backing, geotextiles, and disposable medical/hygiene products. Since the fabric production is combined with fiber production, the process is generally more economical than when using staple fiber to make nonwoven fabrics.
Isotactic polypropylene is the most widely used polymer for spunbond nonwovens production. It provides the highest yield (fiber per kilogram) and covering power at the lowest cost because of its low density. Considerable advances have been made in the manufacture of polypropylene resins and additives since the first spunbond polypropylene fabrics were commercialized in the 1960s. Although unstabilized polypropylene is rapidly degraded by UV light, improved stabilizers permit several years of outdoor exposure before fiber properties deteriorate. To reduce cost, scrap or polypropylene fibers of inferior quality may be repelletized and then blended in small amounts with fresh polymer to produce first grade spunbond fabrics. This is very advantageous and important in a highly competitive industry.
Spunbond polyester fabrics typically have more uniform properties than other structures of nonwoven. They are produced using medium to coarse dpf continous filament fibers.
